Methods: Clinical data of patients who underwent inguinal hernia repair in the Department of Gastrointestinal Hernia Surgery of Nanchong Central Hospital from January 2020 to December 2023 were retrospectively collected. The patients were divided into three groups, ≥70 years old day surgery group, ≥70 years old inpatient surgery group and <70 years old day surgery group, according to the mode of admission and age, and the propensity score matching method was used to match the ≥70 years old day surgery group with the ≥70 years old inpatient surgery group, and the ≥70 years old daysurgerysurgery group with the <70 years old day surgery group, respectively, in a two-by-two study. The clinical indicators of postoperative recovery period between the two groups were compared after matching, respectively. Results: In this study, 230 patients ≥70 years old who underwent day surgery, 645 patients ≥70 years old who underwent inpatient surgery, and 570 patients <70 years old who underwent day surgery were included in this study. 230 patients were included in each of the two groups of ≥70 years old day surgery group and ≥70 years old inpatient surgery group as a comparative study after 1:1 propensity-matched study, and both groups were compared with each other in terms of Intraoperative bleeding, operative time, postoperative fever, vomiting, and urinary retention, VTE, seroma, incision healing, discharge VAS pain score, and recurrence were compared without significant differences (P>0.05). However, the two groups of patients were compared in terms of hospitalization cost (≥70 years old day surgery group (12990.42±3399.614 CNY), ≥70 years old inpatient surgery group (15006.84±3045.871 CNY), P<0.001) the cost of the inpatient surgery group was higher than the cost of the day surgery group, and the difference was statistically significant. Also after a 1:1 propensity matching study, 155 patients were included in each of the two groups of ≥70 years old day surgery group and <70 years old day surgery group as a comparative study, and it was found that there was no significant difference in the comparison between the two groups in terms of Intraoperative bleeding, operative time, inpatient costs, postoperative fever, vomiting, urinary retention, VTE, seromas, incision healing, discharge VAS pain, and recurrence (P>0.05). Conclusion: A retrospective study based on PSM matching has shown that it is safe and feasible to perform daytime hernia surgery in elderly patients over 70 years of age who are well assessed for anesthetic risk and who have underlying medical conditions that do not require complex multidisciplinary care. Health sciences/Medical research/Pre clinical studies Health sciences/Signs and symptoms/Digestive signs and symptoms Day surgery inguinal hernia repair 70 year old elderly patient Figures Figure 1 Introduction Inguinal hernia is one of the common underlying diseases in surgery, with over 20 million patients worldwide receiving surgical treatment each year[ 1 ]. With the aging of the population, the incidence rate of inguinal hernia gradually increases ,Inguinal hernia is common in elderly males, with an estimated incidence in patients older than 70 years of 15:1000. Whether it is open hernia repair or laparoscopic hernia repair, inguinal hernia surgery has the advantages of minimal trauma, fast recovery, and mild pain, making it suitable for day surgery[ 2 – 4 ]. Elderly patients often have a higher risk of adverse events during the perioperative period due to the presence of multiple underlying diseases, According to the guidelines for day surgery inguinal hernia, the age requirement for patient admission is not solely a limiting factor for day surgery, but is evaluated based on the patient's own condition, surgery, anesthesia, and severity of complications[ 5 ]. There are literature reports that ventral hernia repair can be performed reasonably safely and effectively even in this potentially risky cohort, even in patients over 70 years old[ 3 , 6 ]. However, there are only few studies on inguinal hernia repair as a day surgery for patients older than 70 years. In the International Guidelines, the current and future challenge is noted as the provision of more effective, less traumatic, and safer day surgery for elderly patients[ 7 ]. Therefore, we aimed to investigate the effectiveness and safety of inguinal hernia repair as a day surgery for patients older than 70 years by Retrospective study and analysis were conducted by collecting postoperative recovery outcome indicators of 70 year old patients who underwent day surgery, 70 year old patients who underwent inpatient surgery, and < 70 year old patients who underwent inguinal hernia repair surgery in the past two years at our center. Materials and methods Data source and ethics statement In Nanchong Central Hospital, we maintain a prospective database, including all inguinal hernia repairs performed in our department since January 2020. This study is a retrospective review of prospectively collected data from this database. Retrospective collection of clinical data of patients who underwent inguinal hernia repair surgery in the Department of Gastrointestinal Hernia Surgery at Nanchong Central Hospital from January 2020 to December 2023. This study has been approved by the Ethics Committee of Nanchong Central Hospital (number: 2021 review (017)). In addition, all methods were conducted in accordance with the guidelines and regulations of the Chinese Clinical Research Registration Center (ChiCTR2300074099) .Approval for this study did not require written informed consents from the enrolled patients, because it was a retrospective review of prospectively collected data. Patient selection Patients who were diagnosed based on history inquiry, physical examination, and ultrasound imaging were included. The decision to hospitalize or to perform day surgery is based on an assessment of the patient's condition. In the International groin hernia management guidelines, day surgery is defined as discharge on the same day of surgery after a period of medically supervised recovery. Surgical treatments are operated by well-established senior surgeons, and the choice of mesh type and mesh fixation method is a joint decision between the surgeon and the patient. Inclusion criteria: (1) Patient age ≥ 18 years old; (2) Simple or combined inguinal hernia (including unilateral or bilateral), inguinal hernia, inguinal hernia, femoral hernia, and simple recurrent hernia; (3) Patients with ASA scores of I, II, or III; (4) The patient has sufficient continuity of care at home; (5) The case files are complete and sound, and patients who have been followed up for at least one year. Exclusion criteria: (1) Pregnant or lactating women; (2) Hernia with strangulation, strangulation, or signs of infection; (3) Individuals with mental illnesses who are unable to cooperate. Data collection and follow‑up Baseline data: general patient information was collected through the inpatient medical record system, including: age, gender, BMI, disease duration, comorbidities (hypertension, diabetes, COPD, Cardiovascular events, BPO: benign prostatic obstruction, Uremia, Cirrhosis, Stroke history, Abdominal surgery history, Cancer of history, history of tobacco use, history of alcohol use disorder, anesthesia risk ASA risk assessment (I, II, III), Gibert hernia typing (I, II, III, IV, V, VI, VII), Laterality hernia(Unilateral ,Bilateral), anesthesia choice (general, Intravertebral, Epidural, local), and surgical modality (TEP, TAPP, Lichenstein, preperitoneal repair). Observation indicators: intraoperative bleeding, operative time, hospitalization cost, postoperative complications (fever, nausea, vomiting, urinary retention), discharge VAS pain score, VTE events, incidence of seroma, incision healing (well, swelling, fat liquefaction), and recurrence at 1 year postoperatively. Telephone follow-up interviews were conducted at 7 days,1 month, 3 months, 6 months, and 1 year after surgery. Statistical analysis SPSS 27.0 statistical software was applied for analysis. Measurement information that conformed to normal distribution was expressed as mean ± standard ( ¯x ± s), and group comparisons were made using the paired t-test. Data without repeated measurements were analyzed by ANOVA; count data were expressed as the number of cases (%), and group comparisons were made using the χ2 test or Fisher's exact probability method. p < 0.05 was considered a statistically significant difference. This study was a non-randomized study, in order to balance the baseline differences between groups, the nearest neighbor matching method was used to match the two groups with 1:1 propensityscore matching (PSM), with a caliper value of 0.02. Matching factors included in the model included the selection of variables based on the comparative differences in basic information. General information, complication rates and perioperative conditions were compared between the two groups of patients after matching. Stratified analysis of matched patients according to the hospitalization pattern was performed to compare the differences in postoperative complication rates and perioperative conditions between the two groups, respectively. Two-sided test, test level α = 0.05. Result 1.Selection and grouping of study participants (≥ 70 years day surgery group, ≥ 70 years inpatient surgery group and < 70 years day surgery group ) A total of 2026 patients were selected from the database for this study. A detailed flow chart of the process of selecting patients (including the inclusion and exclusion criteria used in the database) is shown in Fig. 1 . Excluding patients who were lost to follow-up and unplanned studies in the group (inpatients < 70 years of age undergoing inpatient surgery),Finally, 1,445 patients with inguinal hernia repair were screened, including 230 patients ≥ 70 years of age who underwent day surgery, 645 patients ≥ 70 years of age who underwent general inpatient surgery, and 570 patients < 70 years of age who underwent day surgery. 2.Comparison of baseline data before and after propensity score matching between patients in the ≥ 70-year-old day surgery group and the ≥ 70-year-old inpatient surgery group. In the data of the two groups of patients selected for this study, the first two groups of patients were compared and found that there were differences in the comparison between the ≥ 70-year-old day surgery group and the ≥ 70-year-old inpatient surgery group patients in age, diabetes, COPD, stroke history,history of cancer, anesthesia risk ASA score, hernia repair technique, and anesthesia choice(P < 0.05). The variables were first variables as covariates to establish a logistic regression model to analyze the correlation, and finally eight variables were chosen to be included as covariates to establish a regression model based on the results of the test of equilibrium, including age, diabetes, COPD, stroke history, history of cancer, anesthesia risk ASA score, hernia repair technique, and anesthesia choice. After matching, 230 pairs were successfully matched, totaling 460 cases. After statistical testing, the difference in baseline information between the matched ≥ 70 years old day surgery group and the ≥ 70 years old inpatient surgery group was not statistically significant(P > 0.05), and baseline comparability was good (Table 1 ).

After 1:1 matching of the two groups of patients, by comparing the intraoperative and postoperative clinical indexes, it was found that there was no significant difference between two groups of patients aged ≥ 70 years in the day surgery group and ≥ 70 years in the inpatient surgery group in the comparison of Intraoperative bleeding(7.77 ± 4.455 vs, 7.88 ± 4.666 ml), operation time(59.03 ± 27.866 vs59.30 ± 18.650min), postoperative fever(3(1.3%)vs1(0.4%)), vomiting (2(0.9%) vs 4(1.7%)), urinary retention(34(14.8%) vs 29(12.6%)), VTE events(2(0.9%) vs 1(0.4%)), seroma(30(13.0%) vs 30(13.0%)), Seroma fluid volume(5.13 ± 15.023 vs 6.10 ± 16.500 ml)), scrotal pain(3(1.3%) vs 4(1.7%)) ,incision healing(well: 226(98.3%) vs 222(96.5%), swelling: 4(1.7%) vs 6(2.6%), Fat liquefaction: 0(0%) vs 2(0.9%)), Postoperative VAS score(1day: 1.48 ± 1.407vs1.31 ± 1.158,3day: 0.80 ± 1.062 vs 0.68 ± 0.882, 7day: 0.22 ± 0.519 vs 0.18 ± 0.409), and no recurrence (P > 0.05). However, the two groups of patients in the hospitalization cost comparison( (≥ 70 years old day surgery group: (12990.42 ± 3399.614 CNY) vs ≥ 70 years old inpatient surgery group (15006.84 ± 3045.871 CNY), P < 0.001) )the cost of inpatient surgery group was higher than the cost of the day surgery group, and the difference was statistically significant (Table 2 ).

Comparison of baseline data before and after propensity score matching between patients in the ≥ 70-year-old day surgery group and the < 70-year-old day surgery group. In order to increase the rigor and scientific validity of the study, we further analyzed the data of patients with ≥ 70 years day surgery group versus < 70-year-old day surgery group patients retrospectively statistically. The data of the two groups of patients selected for this study were collected from the ≥ 70 years old day surgery group (n = 230) and the < 70 years old day surgery group (n = 570), and the statistical comparison between the two groups of patients in the first instance revealed that there was a difference between the two groups of patients in terms of hypertension, diabetes, COPD, cardiovascular disease, Uremia, Cancer of history, Abdominal surgery history, Tobacco use, alcohol use disorder, risk of anesthesia ASA score, Laterality(Unilateral, Bilateral), hernia repair technique and anesthesia choice. The variables were first variables as covariates to establish logistic regression models to analyze the correlation, and finally thirteen variables were chosen to be included as covariates to establish regression models based on the results of the test of equilibrium: hypertension, diabetes, COPD, cardiovascular disease, Uremia, Cancer of history, Abdominal surgery history, Tobacco use, alcohol use disorder, risk of anesthesia ASA score, Laterality(Unilateral, Bilateral), hernia repair technique and anesthesia choice. After PSM, 156 pairs were successfully matched, totaling 312 cases. After statistical testing, there was no statistically significant difference in baseline data between the matched ≥ 70 years old day surgery group and 0.05), implying that PSM effectively mitigated potential confounding factors, thereby enhancing the comparability of the two groups (Table 3 ).

Comparison of postoperative clinical indicators between two groups of patients in the day surgery group ≥ 70 years of age and the day surgery group < 70 years of age after propensity score matching. After 1:1 matching of the two groups of patients, by comparing the intraoperative and postoperative clinical indexes, it was found that there was no significant difference in the comparison between the day surgery group ≥ 70 years of age and the day surgery group < 70 years of age patients in terms of Intraoperative bleeding(7.75 ± 4.416 vs 7.43 ± 4.480 ml), operative time༈60.67 ± 25.655 Vs 61.22 ± 26.722༉, hospitalization cost༈12665.14 ± 2786.712 vs 13064.79 ± 8748.388༉, postoperative fever༈1(0.6%) vs 1(0.6%)༉, vomiting༈2(1.3%) vs 0(0.0%)༉, urinary retention༈14(9.0%) vs 12(7.7%)༉, VTE events (1(0.6%) vs 0(0.0%)), seroma(27(17.3%) vs 31(19.9%)), Seroma fluid volume (6.85 ± 17.102 vs 8.40 ± 18.573 ml), scrotal pain(3(1.9%)Vs 5(3.2%)),incision healing(well: 154(98.7%) vs 153(98.1%), swelling: 2(1.3%) vs 3(1.9%)), Postoperative VAS score(1day:1.47 ± 1.375vs1.55 ± 1.005,3day:0.78 ± 1.038vs 0.78 ± 0.947,7day:0.21 ± 0.478vs0.23 ± 0.519), and no recurrence (P > 0.05) (Table 4 ). Therefore, there is no significant difference in postoperative complications and other adverse effects of inguinal hernia in the elderly carried out in the day surgery mode, which is feasible.

This has stemmed from the recent rapid development in techniques, equipment and drugs used in surgery and anaesthesia[ 8 ]. Day surgery has the advantages of efficient utilization of medical resources, reduction of national social expenditures, shortening of preoperative waiting time, and reduction of patient costs, and its choice of surgical diseases has been increasing and its safety has been improving[ 9 ]. As one of the common surgical diseases, a large number of studies have confirmed that day surgery for inguinal hernia has the advantages of reducing patients' hospitalization queuing time, shortening hospitalization time, decreasing medical expenditures, decreasing the incidence of nosocomial infections, and accelerating patients' recovery compared to the traditional inpatient surgical model[ 10 – 12 ]. However, the ambulatory surgery model requires a high level of patient admission, and many ambulatory surgery centers remain cautious about ambulatory surgery admission of elderly patients, despite the fact that age is not a necessary condition for restriction according to the guidelines[ 13 , 14 ]. Inguinal hernia is a growing health care issue in rapidly aging societies, because the incidence of inguinal hernia increases drastically with advancing age[ 15 ]. But the rate of intentional inguinal hernia surgery in the elderly will further increase as inguinal hernia health education becomes more widespread and people demand a higher quality of life[ 16 ]. However, the elderly have more surgery related morbidity and mortality compared with the younger population. In addition, the elderly are especially vulnerable to several neurologic, cardiac, and pulmonary complications due to anesthesia, postoperative pain management, and medications after elective surgeries[ 17 , 18 ]. Several studies have focused on this issue to clarify the safety and feasibility of hernia repair in the elderly with an age limit of 65 years[ 19 ], and day surgical modalities are seldom implemented for patients over 70 years of age[ 20 ]. It has been reported in the literature after careful perioperative evaluation, Laparoscopic inguinal hernia repair as a 24-h day surgery was safe and effective for patients over 80 years old[ 21 ].Therefore, in order to confirm that day surgery is safe and feasible in elderly patients, a retrospective analysis of patients with inguinal hernia admitted in the past three years was performed at our center. In our study, In order to verify the feasibility of the ambulatory surgery model in elderly patients, Pairing study was conducted between the group undergoing day surgery at ≥ 70 years old and the group undergoing regular inpatient surgery at ≥ 70 years old, as well as between the group undergoing day surgery at ≥ 70 years old and the group undergoing day surgery at < 70 years old. As the study was retrospective, there were more confounders, not effectively controlled for baseline, and the intervening imbalance affected the veracity of some of the findings. Propensity score matching is a method to control confounders. It can effectively reduce confounding factors and equalize the differences between the baseline information of the experimental group and the control group, making the two comparable. After propensity score matching, there was no difference in the baseline comparisons between the two groups, making the postoperative clinical indicators comparable between the two groups[ 22 ]. There was no significant difference in intraoperative bleeding, operative time, postoperative fever, vomiting, urinary retention, VTE, seroma, incision healing, postoperative VAS pain, and recurrence follow-up in the comparison of the two groups of patients aged 70 years in the day surgery versus ≥ 70 years in the general inpatient hospitalization group. However, the cost of inpatient group was higher than the cost of ambulatory group in the ≥ 70 years old inpatient group, which may be caused by the long hospitalization time and the need for multidisciplinary diagnosis and treatment, which led to the increase in the cost, in conclusion, the prognosis of elderly patients who underwent the ambulatory surgery mode was consistent with that of inpatient mode after the operation. In order to further compare the elderly patients with younger patients for daytime comparisons with or without differences ≥ 70 years of age for daytime surgery versus < 70 years of age for daytime surgery after propensity score matching in both groups, No statistically significant difference was found in the incidence of postoperative complications between the two groups, even after we performed subgroup analyses for confounding factors. which further demonstrates the safety of daytime surgery in elderly patients. Therefore, the success of > 70years old day surgery as a day surgery is still significant for the perioperative experience and the improvement of quality of life of this group of patients. Although we proved that it is feasible to perform day surgery for elderly patients over 70 years old after propensity comparison, the risk of surgical anesthesia increases with the increase of patients' age and the increase of systemic conditions combined with underlying diseases[ 23 ]. after evaluating the risk of anesthesia for the patients, laparoscopic surgery or open surgery should be selected based on the needs of the condition, the patient's wishes, and the habit of the operator[ 24 ]. for the elderly patients who have more comorbidities and are unable to tolerate general anesthesia For elderly patients with more comorbidities who are unable to tolerate general anesthesia, open surgery should be chosen, which can even be completed under local anesthesia. ASA grades 3 and 4 patients can undergo day case inguinal hernia repair, with similar complication rates to ASA grades 1 and 2 patients, when surgery is performed under local anaesthesia [ 25 , 26 ].Elderly patients have high prevalence of hypertension, diabetes, pulmonary disease and cardiovascular disease, and should be invited to the relevant departments to give active intervention and regulation 1 week before day surgery, and then evaluate whether to prepare for day surgery. Postoperative urinary retention, nausea, vomiting, and pain are major risk factors for delayed discharge[ 27 , 28 ].After surgery, patients should be encouraged to get out of bed early, enter liquid diet, encourage early urination, defecation and other rehabilitation treatments, and even give medication to improve the condition, to avoid deep venous thrombosis, pulmonary infection, urinary retention etc[ 29 – 31 ]. Due to the short hospitalization time of daytime patients, postoperative observation time can be appropriately prolonged for elderly patients with potential postoperative risks, and those who have not experienced any abnormalities during the observation period can return home. Before discharge from the hospital according to the day surgery anesthesia PADS (postanesthesia discharge score) requirements for discharge[ 32 ]. after discharge in a timely manner to give remote guidance on postoperative recovery and outpatient follow-up, Seroma has been one of the most common complications after inguinal hernia repair and can be improved by self-absorption or puncture drainage[ 33 ]. follow-up patients postoperative incision healing, pain, etc., to avoid neglecting the occurrence of postoperative complications and delayed treatment time, if necessary, feasible community health care institutions, such as further rehabilitation treatment[ 34 , 35 ]. Conclusion In conclusion, elderly patients over 70 years of age after preoperative anesthesia risk assessment is good, there are underlying diseases, after the complex multidisciplinary cooperation does not require diagnosis and treatment of regulation, the reasonable development of day surgery is safe, feasible, in saving social resources, control of medical expenditures, reduce the cost of medical care of patients and their families have the advantage of, it is worthwhile to carry out the promotion of all levels of medical consultation and treatment centers. However, the limitations of this study was insufficient control of confounding factors, inadequate study scale, and incomplete outcome follow-up. Therefore, further in-depth discussion and supplement is needed. Declarations Ethical approval The study was approved by the Ethics Committee of Nanchong Central Hospital(NO: 2021 review (017)).

The data of the two groups of patients selected for this study were collected from the \u0026ge;\u0026thinsp;70 years old day surgery group (n\u0026thinsp;=\u0026thinsp;230) and the \u0026lt;\u0026thinsp;70 years old day surgery group (n\u0026thinsp;=\u0026thinsp;570), and the statistical comparison between the two groups of patients in the first instance revealed that there was a difference between the two groups of patients in terms of hypertension, diabetes, COPD, cardiovascular disease, Uremia, Cancer of history, Abdominal surgery history, Tobacco use, alcohol use disorder, risk of anesthesia ASA score, Laterality(Unilateral, Bilateral), hernia repair technique and anesthesia choice. The variables were first variables as covariates to establish logistic regression models to analyze the correlation, and finally thirteen variables were chosen to be included as covariates to establish regression models based on the results of the test of equilibrium: hypertension, diabetes, COPD, cardiovascular disease, Uremia, Cancer of history, Abdominal surgery history, Tobacco use, alcohol use disorder, risk of anesthesia ASA score, Laterality(Unilateral, Bilateral), hernia repair technique and anesthesia choice. After PSM, 156 pairs were successfully matched, totaling 312 cases. After statistical testing, there was no statistically significant difference in baseline data between the matched\u0026thinsp;\u0026ge;\u0026thinsp;70 years old day surgery group and \u0026lt;\u0026thinsp;70 years old day surgery group(P\u0026thinsp;\u0026gt;\u0026thinsp;0.05), implying that PSM effectively mitigated potential confounding factors, thereby enhancing the

However, the elderly have more surgery related morbidity and mortality compared with the younger population.

As the study was retrospective, there were more confounders, not effectively controlled for baseline, and the intervening imbalance affected the veracity of some of the findings. Propensity score matching is a method to control confounders. It can effectively reduce confounding factors and equalize the differences between the baseline information of the experimental group and the control group, making the two comparable. After propensity score matching, there was no difference in the baseline comparisons between the two groups, making the postoperative clinical indicators comparable between the two groups[\u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThere was no significant difference in intraoperative bleeding, operative time, postoperative fever, vomiting, urinary retention, VTE, seroma, incision healing, postoperative VAS pain, and recurrence follow-up in the comparison of the two groups of patients aged 70 years in the day surgery versus \u0026ge;\u0026thinsp;70 years in the general inpatient hospitalization group. However, the cost of inpatient group was higher than the cost of ambulatory group in the \u0026ge;\u0026thinsp;70 years old inpatient group, which may be caused by the long hospitalization time and the need for multidisciplinary diagnosis and treatment, which led to the increase in the cost, in conclusion, the prognosis of elderly patients who underwent the ambulatory surgery mode was consistent with that of inpatient mode after the operation.

The patients were divided into three groups, ≥70 years old day surgery group, ≥70 years old inpatient surgery group and \u0026lt;70 years old day surgery group, according to the mode of admission and age, and the propensity score matching method was used to match the ≥70 years old day surgery group with the ≥70 years old inpatient surgery group, and the ≥70 years old daysurgerysurgery group with the \u0026lt;70 years old day surgery group, respectively, in a two-by-two study.

However, the two groups of patients were compared in terms of hospitalization cost (≥70 years old day surgery group (12990.42±3399.614 CNY), ≥70 years old inpatient surgery group (15006.84±3045.871 CNY), P\u0026lt;0.001) the cost of the inpatient surgery group was higher than the cost of the day surgery group, and the difference was statistically significant. Also after a 1:1 propensity matching study, 155 patients were included in each of the two groups of ≥70 years old day surgery group and \u0026lt;70 years old day surgery group as a comparative study, and it was found that there was no significant difference in the comparison between the two groups in terms of Intraoperative bleeding, operative time, inpatient costs, postoperative fever, vomiting, urinary retention, VTE, seromas, incision healing, discharge VAS pain, and recurrence (P\u0026gt;0.05).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusion:\u003c/strong\u003e A retrospective study based on PSM matching has shown that it is safe and feasible to perform daytime hernia surgery in elderly patients over 70 years of age who are well assessed for anesthetic risk and who have underlying medical conditions that do not require complex multidisciplinary care.\u003c/p\u003e","manuscriptTitle":"A study to analyze the safety and feasibility of inguinal hernia repair in day surgery mode in elderly patients over 70 years old ： A propensity score- matched study","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-12-19 12:34:38","doi":"10.21203/rs.3.rs-5402644/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"b06ef913-0917-4d73-b284-b65239d804fb","owner":[],"postedDate":"December 19th, 2024","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[{"id":40953598,"name":"Health sciences/Medical research/Pre clinical studies"},{"id":40953599,"name":"Health sciences/Signs and symptoms/Digestive signs and symptoms"}],"tags":[],"updatedAt":"2025-09-16T15:38:48+00:00","versionOfRecord":[],"versionCreatedAt":"2024-12-19 12:34:38","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-5402644","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-5402644","identity":"rs-5402644","version":["v1"]},"buildId":"qtupq5eGEP_6zYnWcrvyt","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
