This 15-year single-referral-center study describes a consecutive series of 215 patients with diaphragmatic endometriosis treated using laparoscopy and, when needed, videothoracoscopy (VATS), with lesions classified as foci, plaques, or nodules and managed using a proposed standardized surgical algorithm. Most lesions were on the right hemidiaphragm (91%), with 62% foci, 11% plaques, and 27% nodules; when pleural involvement, diaphragmatic hernia, or thoracic-side lesions were present, VATS was performed alone or combined with laparoscopy, totaling 26 thoracic-related procedures. The authors report that surgical techniques were matched to lesion type, including argon beam coagulation/diathermocoagulation for foci, peritoneal stripping for plaques, and nodulectomy or full-thickness resection for nodules. The paper’s main limitation is that it is a retrospective single-center experience without an explicit comparison group, and it frames standardization as a way to reduce under- or overtreatment and complications rather than directly measuring outcomes against alternatives. This paper is centrally about endometriosis — it focuses on minimally invasive surgical management of diaphragmatic endometriosis and standardizing treatment by lesion type.

Abstract

BackgroundDiaphragmatic endometriosis (DE) is a rare and often misdiagnosed condition. Most of the times it is asymptomatic and due to the low accuracy of diagnostic tests, it is almost always detected during surgery for pelvic endometriosis. Its management is challenging and, until now, there are not guidelines about its treatment.MethodsWe describe a consecutive series of patients with DE managed by laparoscopy and videothoracoscopy (VATS) in our referral center in a period of 15 years. We developed a flow-chart classifying DE implants in foci, plaques and nodules and proposing an algorithm with the aim of standardizing the surgical approach.Results215 patients were treated for DE. Lesions were almost always localized on the right hemidiaphragm (91%), and the endometriotic implants were distributed as: foci in 133 (62%), plaques in 24 (11%) and nodules in 58 patients (27%), respectively. In all cases of isolated pleural involvement, concomitant diaphragmatic hernia or lesions of the thoracic side of the diaphragm VATS was performed, alone or combined with laparoscopy, resulting in a total of 26 procedures. Following the proposed algorithm, specific surgical techniques were identified as the better approaches for the different types of the lesion, such as Argon Beam Coagulation and diathermocoagulation for diaphragmatic foci, peritoneal stripping for plaques, and nodulectomy or full-thickness resection of diaphragm for nodules.ConclusionsIt is crucial to standardize the surgical approach of DE, according to the type of lesion, thus reducing the rate of under- or over-treatments and intra or postoperative complications. This kind of surgery should be performed in a Referral Center by a gynecologic surgeon with oncogynecologic expertise and skills, with the eventual support of a laparoscopic general surgeon, a specialized thoracic surgeon and a trained anesthesiologist.

Abstract

Background Diaphragmatic endometriosis (DE) is a rare and often misdiagnosed condition. Most of the times it is asymptomatic and due to the low accuracy of diagnostic tests, it is almost always detected during surgery for pelvic endometriosis. Its management is challenging and, until now, there are not guidelines about its treatment.

Methods

We describe a consecutive series of patients with DE managed by laparoscopy and videothoracoscopy (VATS) in our referral center in a period of 15 years. We developed a flow-chart classifying DE implants in foci, plaques and nodules and proposing an algorithm with the aim of standardizing the surgical approach.

Results

215 patients were treated for DE. Lesions were almost always localized on the right hemidiaphragm (91%), and the endometriotic implants were distributed as: foci in 133 (62%), plaques in 24 (11%) and nodules in 58 patients (27%), respectively. In all cases of isolated pleural involvement, concomitant diaphragmatic hernia or lesions of the thoracic side of the diaphragm VATS was performed, alone or combined with laparoscopy, resulting in a total of 26 procedures. Following the proposed algorithm, specific surgical techniques were identified as the better approaches for the different types of the lesion, such as Argon Beam Coagulation and diathermocoagulation for diaphragmatic foci, peritoneal stripping for plaques, and nodulectomy or full-thickness resection of diaphragm for nodules.

Conclusions

It is crucial to standardize the surgical approach of DE, according to the type of lesion, thus reducing the rate of under- or over-treatments and intra or postoperative complications. This kind of surgery should be performed in a Referral Center by a gynecologic surgeon with oncogynecologic expertise and skills, with the eventual support of a laparoscopic general surgeon, a specialized thoracic surgeon and a trained anesthesiologist.
