Case: The patient, a man in his 60s, underwent laparoscopic abdominoperineal resection for lower rectal cancer at another hospital. Thirty months after the surgery, he was referred to our department for surgery for a recurrent tumor in the pelvis. Magnetic resonance imaging showed a tumor on the dorsal prostate that was suspected to have invaded a seminal vesicle. Surgical findings: After incision in the previous perineal surgical wound, a subcutaneous incision was made and a GelPOINT mini was attached. Airflow was applied with the AirSeal system, and the surgery was performed laparoscopically. To accurately identify the dissection layers and avoid urethral injury, intraoperative urethrography was performed as necessary, and dissection was performed with an electrocautery and ultrasonic coagulation incision device while confirming the position of the urethra and forceps. The prostate was safely identified by urethrography and separated from the firm tumor. After dissecting the fatty tissue surrounding the tumor, the affected seminal vesicle was partially resected. The dorsal side of the tumor was dissected using the coccygeal bone and the levator ani muscle as guides, and the tumor was removed. Conclusion: In select cases, the TaTME technique may allow minimally invasive surgery using only a transanal or transperineal approach. Introduction Pelvic recurrence of rectal cancer often requires invasive surgery, such as total pelvic visceral excision, that can lead to problems, such as adhesions associated with reoperation, increased operation time and blood loss, and functional impairment caused by the combined resection of other organs. The two-team approach with transanal total mesorectal excision (TaTME) for recurrent tumors is useful and provides a good visual field unaffected by previous surgery and shortens the operative time (1–3). We have previously reported that urethrography in TaTME is useful to determine the appropriate dissection line (4). In this report, we describe a case of pelvic recurrence of rectal cancer invading a seminal vesicle after abdominoperineal resection, which was removed only by a transperineal approach with the addition of urethrography. Case The patient, a man in his 60s, underwent laparoscopic abdominoperineal resection for lower rectal cancer at another hospital. Thirty months after the surgery, he was referred to our department for surgery for a recurrent tumor in the pelvis. Magnetic resonance imaging showed a tumor on the dorsal prostate that was suspected to have invaded a seminal vesicle. The tumor shrunk after chemotherapy with FOLFIRI (irinotecan 180 mg/m 2 , leucovorin 200 mg/m 2 intravenously, bolus 5-fluorouracil 400 mg/m 2 , and 5-fluorouracil infusion at 2400 mg/m 2 /46 h) + panitumumab. Because the small intestine had dropped into the pelvis and extensive adhesions were expected in the abdominal cavity, a transperineal approach was planned, and the affected seminal vesicle was scheduled for partial combined resection. Surgical findings After incision in the previous perineal surgical wound, a subcutaneous incision was made and a GelPOINT mini (Applied Medical Japan Headquarters, Tokyo, Japan) was attached. Airflow was applied with the AirSeal system (Conmed, Utica, NY, USA), and the surgery was performed laparoscopically. First, ventral dissection was initiated. To accurately identify the dissection layers and avoid urethral injury, intraoperative urethrography was performed as necessary, and dissection was performed with an electrocautery and ultrasonic coagulation incision device while confirming the position of the urethra and forceps. The prostate was safely identified by urethrography and separated from the firm tumor. After dissecting the fatty tissue surrounding the tumor, the affected seminal vesicle was partially resected. The dorsal side of the tumor was dissected using the coccygeal bone and the levator ani muscle as guides, and the tumor was removed. A drain was inserted through the gluteal region into the pelvic floor, and the skin was sutured closed. There was no intraoperative injury to other organs, such as the small intestine, and the surgery was completed using only a transperineal approach. The surgery time was 134 minutes, with only 5 ml of blood loss. There were no postoperative complications, and the patient was discharged 8 days after the surgery. Histopathological examination indicated negative circumferential resection margins, and no local recurrence was observed 18 months after surgery. Discussion In surgery for recurrent tumors of rectal cancer, a transanal or transperineal endoscopic approach provides a good surgical view that is less affected by previous surgery. The TaTME technique allows for a deep pelvic approach without laparotomy, making it possible to perform minimally invasive surgery in patients with expected intraperitoneal adhesions or poor general condition. However, a transanal or transperineal approach requires an understanding of the unique anatomy, which may be even more difficult in reoperation. In male patients, the use of intraoperative urethrography reduces the risk of urethral injury because the position of the forceps can be determined in real time. However, there are limitations to this approach. In post-abdominoperineal resection case s, care must be taken if the small intestine has dropped to the deepest pelvic region, as adhesion of the small intestine may be a problem even with a transperineal approach. Additionally, owing to the limited extent of resection, care must be taken to ensure negative circumferential resection margins. In conclusion, in select cases, the TaTME technique may allow minimally invasive surgery using only a transanal or transperineal approach.

Thirty months after the surgery, he was referred to our department for surgery for a recurrent tumor in the pelvis. Magnetic resonance imaging showed a tumor on the dorsal prostate that was suspected to have invaded a seminal vesicle.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eSurgical findings:\u003c/strong\u003e After incision in the previous perineal surgical wound, a subcutaneous incision was made and a GelPOINT mini was attached. Airflow was applied with the AirSeal system, and the surgery was performed laparoscopically. To accurately identify the dissection layers and avoid urethral injury, intraoperative urethrography was performed as necessary, and dissection was performed with an electrocautery and ultrasonic coagulation incision device while confirming the position of the urethra and forceps. The prostate was safely identified by urethrography and separated from the firm tumor. After dissecting the fatty tissue surrounding the tumor, the affected seminal vesicle was partially resected. The dorsal side of the tumor was dissected using the coccygeal bone and the levator ani muscle as guides, and the tumor was removed.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusion: \u003c/strong\u003eIn select cases, the TaTME technique may allow minimally invasive surgery using only a transanal or transperineal approach.\u003c/p\u003e","manuscriptTitle":"Transperineal approach alone as minimally invasive surgery for pelvic recurrence of rectal cancer after abdominoperineal resection","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-12-19 09:11:11","doi":"10.21203/rs.3.rs-5653986/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-02-11T18:24:59+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-01-30T20:41:20+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-01-24T08:35:15+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"68356039920759738621940862170532387118","date":"2025-01-20T15:27:59+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"229726538802114822761307074202473244769","date":"2025-01-07T17:19:58+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-01-07T11:28:38+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2024-12-23T17:11:25+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2024-12-17T12:07:44+00:00","index":"","fulltext":""},{"type":"submitted","content":"Techniques in Coloproctology","date":"2024-12-16T12:45:23+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
