Abstract
BACKGROUND Total pelvic exenteration, a surgical procedure for patients with highly advanced primary and recurrent rectal cancer, is technically demanding. IMPACT OF INNOVATION We report the utility of a transanal minimally invasive surgical approach to total pelvic exenteration. TECHNOLOGY MATERIALS AND METHODS A 2-team approach with a laparoscopic transabdominal approach and transanal minimally invasive surgery was adopted. During the transabdominal approach in the pelvis, dissection was performed to remove the pelvic organs and visceral branches of the internal iliac vessels. The dissection goal via the transabdominal approach is the levator ani. During the transperineal approach, dissection is performed along the levator ani, and the tendinous arch of the levator ani is penetrated at the lateral side to achieve rendezvous between the 2 approaches. The levator ani is then dissected circumferentially, with identification of the internal pudendal vessels passing through the levator ani at the 4 o'clock and 8 o'clock positions, known as Alcock's canal. The anterior wall of Alcock's canal is formed by the coccygeus muscle and sacrospinous ligament, which are dissected by the transperineal approach to open Alcock's canal, thus obtaining a clear view of the internal pudendal vessels. On the anterior side, the urethra is divided with a laparoscopic linear stapler via the transperineal approach. PRELIMINARY RESULTS Eight patients with rectal cancer underwent this procedure. The median (range) blood loss was 200 (120-1520) mL and operating time was 467 (321-833) minutes. Reoperation was performed in 1 internal hernia case; however, there were no mortalities, and there were no cases with severe complications or conversion to open surgery. CONCLUSIONS AND FUTURE DIRECTIONS When performing total pelvic exenteration, transanal minimally invasive surgery offers direct visualization behind the tumor from the anal side and shows the deep pelvic structures, including the retroperitoneal space of the pelvic sidewall.

Current status of transanal total mesorectal excision for rectal cancer and the expanding indications of the transanal approach for extended pelvic surgeries. Dig Endosc 2023; 35:243-254. [PMID: 36342054 DOI: 10.1111/den.14464] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Accepted: 11/04/2022] [Indexed: 11/09/2022]
Abstract
Transanal total mesorectal excision (taTME) has been rapidly accepted as a promising surgical approach to the distal rectum. The benefits include ease of access to the bottom of the deep pelvis linearly over a short distance in order to easily visualize the important anatomy. Furthermore, the distal resection margins can be secured under direct vision. Additionally, a two-team approach combining taTME with a transabdominal approach could decrease the operative time and conversion rate. Although taTME was expected to become more rapidly popularized worldwide, enthusiasm for it has stalled due to unfamiliar intraoperative complications, a lack of oncologic evidence from randomized trials, and the widespread use of robotic surgery. While international registries have reported favorable short- and medium-term outcomes from taTME, a Norwegian national study reported a high local recurrence rate of 9.5%. The characteristics of the recurrences included rapid, multifocal growth in the pelvis, which was quite different from recurrences following traditional transabdominal TME; thus, the Norwegian Colorectal Cancer Group reached a consensus for a temporary moratorium on the performance of taTME. To ensure acceptable baseline quality and patient safety, taTME should be performed by well-trained colorectal surgeons. Although the appropriate indications for taTME remain controversial, the transanal approach is extremely important as a means of goal setting in difficult TME cases and as an aid to the transabdominal approach in various types of extended pelvic surgeries. The benefits in transanal lateral lymph node dissection and pelvic exenteration are presented herein.

Abstract
BACKGROUND The American Joint Committee on Cancer tumor-node-metastasis staging system for rectal cancer defines lateral pelvic lymph nodes (LPLNs) only in the internal iliac region as regional. However, the Japanese Society for Cancer of the Colon and Rectum (JSCCR) staging system, also considers obturator lymph nodes (LNs) as regional. This retrospective cohort study evaluated the oncologic status of obturator LNs in low rectal cancer. METHODS The study identified 3487 patients with pT3-T4 low rectal cancer who had undergone curative resections without preoperative radiotherapy or chemotherapy between 2003 and 2011 in the JSCCR database and divided them into six groups. Overall survival (OS) and recurrence-free survival (RFS) were analyzed by groups. RESULTS Histologic LPLN metastases were identified in 8% (279/3487) of all the patients and in 18.2% (279/1530) of the patients who underwent lateral pelvic node dissection. The 5-year OS and RFS rates of the obturator-LPLN group (P = 0.095) were worse than those of the internal-LPLN group (P = 0.075), but the difference was not significant. The OS of the obturator-LPLN group was similar to that of the resectable liver metastasis group (P = 0.731), and the RFS of the obturator-LPLN group was significantly better than that of the other-LPLN group (P = 0.016). CONCLUSION The prognosis for obturator LN metastases in low rectal cancer was not significantly worse than for internal iliac LN metastases, defined as regional by the current American Joint Committee on Cancer staging system, and the oncologic status of obturator LNs warrants more studies.

A case report of the transanal lateral lymph node dissection with a combined abdominal assisted approach for the lower rectal cancer. Ann Med Surg (Lond) 2022; 73:103173. [PMID: 34976391 PMCID: PMC8683661 DOI: 10.1016/j.amsu.2021.103173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 12/06/2021] [Accepted: 12/06/2021] [Indexed: 11/30/2022] Open
Abstract
Introduction Low and mid rectal cancer cells have the tendency to spread in the lateral pelvic lymph node (LPLN). The Japanese guidelines recommend systematic lymph node dissection when a positive LPLN is suspected or in stages II–III rectal cancer. However, laparoscopic lymph node dissection is complex and challenging. We introduce transanal LPLN dissection using an abdominal approach. Presentation of case A 78-year-old man was diagnosed with advanced rectal cancer. Computed tomography and magnetic resonance imaging showed lower rectal wall thickening and bilateral lateral lymph node swelling. We performed laparoscopic abdominal peritoneal resection with combined bilateral LPLN dissection using abdominal and transanal approaches. He had an uneventful postoperative course with no signs of recurrence at the 5-month follow-up. Discussion LPLN metastases for low rectal cancer especially occur at the bottom of the deep pelvic spaces. As laparoscopic LPLND for low rectal cancer can be complicated, we adopted abdominal and transanal approaches, which provide the advantage of an anatomical view. This procedure may improve lateral pelvic anatomical structure viewing, and may offer advantages over laparoscopic abdominal approaches for visualizing and dissecting LPLNs. Conclusion Curative resection has become available for rectal cancer with transanal LPLN dissection. LPLN dissection with combined abdominal and transanal approaches is a feasible treatment for advanced rectal cancer. Laparoscopic lymph node dissection for low rectal cancer is complex and challenging. The surgical view around the distal internal lymph node (#263d) and the Alcock duct improved with the transanal approach. Ta-LPLND combined with abdominal dissection is feasible and effective for rectal cancer.

Abstract
INTRODUCTION Herein, we describe our novel technique for transecting the dorsal venous complex (DVC) and urethra using a linear stapler inserted through a perineal port during endoscopic pelvic exenteration for pelvic malignancies. MATERIALS AND SURGICAL TECHNIQUE First, a laparoscopic approach is made using a conventional 5-trocar pneumoperitoneum technique. When the Retzius and paravesical spaces are dissected to expose the tendinous arch of the levator ani muscle, the transperineal approach is synchronously begun. After the levator ani muscle and bilateral puboprostatic ligaments are dissected, the DVC and urethra are completely exposed. A linear stapler is inserted through the transperineal port along the dorsal side of the pubic body. The DVC and urethra are carefully compressed and transected with minimal bleeding. We describe four cases of laparoscopic total pelvic exenteration using this technique. Tumor size, operation time, and estimated blood loss ranged from 30-130 mm, 535-877 minutes, and 50-1520 mL, respectively. DISCUSSION Transperineal dissection of the DVC and urethra by linear staplers decreases both operation time and blood loss.

Abstract
Introduction Laparoscopic lateral lymph node dissection (LLND) is an important treatment for patients with lateral lymph node metastasis. Aim To assess the technical feasibility and investigate the surgical outcomes after LLND using the fascia space priority approach for patients with advanced middle and low rectal cancer. Material and methods Consecutive patients undergoing laparoscopic LLND using the fascia space priority approach from June 2017 to June 2020 were identified from 12 medical centres in mainland China. Three anatomic fascia spaces were dissected to establish the boundaries of the LLND, and the obturator and internal iliac lymph nodes were excised in an en bloc manner. Retrospective clinical data including patient characteristics, surgical details, and pathology were analysed. Results A total of 112 patients were identified. All surgeries were completed laparoscopically with no conversions. The mean operation time was 343.6 ±103.8 min for the entire procedure. The median blood loss was 100 ml (range: 100-700 ml). The median lymph node yield was 6 (range: 1-41), and lymph nodes were positive in 39.3% (44/112) of the patients. Sixteen (14.3%) patients had Clavien-Dindo I-II complications, no Clavien-Dindo III-IV complications were identified. The incidence of complications between the bilateral dissection group and the unilateral dissection group was not statistically different (p = 0.19). The complication rate between the "nCRT" group and the "no nCRT" group was not significantly different (p = 0.62) either. There were no perioperative deaths. Conclusions Laparoscopic LLND using the fascia space priority approach is feasible and safe for patients with lateral lymph node metastasis.

Abstract
BACKGROUND AND PURPOSE Total Mesorectal Excisions (TME) is the standard treatment of rectal cancer. It can be performed under laparoscopic, robotic or transanal approach. Inadvertent injury to surrounding structure like autonomic nerves is avoidable, no matter which approach is adopted. Lateral lymph node dissection (LLND) is a less commonly performed pelvic operation involving dissection in an unfamiliar area to most general surgeons. This article aims to clarify all the essential anatomy related to these procedures. METHODS We performed thorough literature search and revision on the pelvic anatomy. Our cases of TME and LLND, under either laparoscopic or transanal approach, were reviewed. We integrated the knowledge from literatures and our own experience. The result was presented in details, together with original figures and intra-operative photos. MAIN FINDINGS Anatomy of pelvic fascia, autonomic nerve system, anal canal and sphincter complex are core knowledge in performing TME and LLND. CONCLUSIONS Thorough understanding of the pelvic anatomy enables colorectal surgeons to master these procedures, avoid complication and perform extended resection. On the other hand, surgeons can appreciate the complex pelvic anatomy easier by seeing the pelvis in opposite angles (transabdominal and transaanal view).

Abstract
BACKGROUND The safe adoption of transanal total mesorectal excision (taTME) has occurred in Australasia as previously reported by the current authors. Planes beyond TME can be utilised in more advanced cases to achieve negative margins during transanal dissection. METHODS In this article we describe how taTME is used to perform an en-bloc partial vaginectomy and aid restore intestinal and vaginal continuity in a young female with a locally advanced rectal cancer and posterior vaginal wall involvement in the pre-treatment magnetic resonance imaging. RESULTS The transanal technique allowed the surgeons to remove a disc of vagina, ensure organ preservation and control the main R1 risk point. An R0 resection was achieved. CONCLUSION This technical note highlights that in experienced hands, taTME may be safely implemented to maintain restorative options in locally advanced rectal cancer requiring resection beyond the total mesorectal excision plane.

Abstract
BACKGROUND Transanal minimally invasive surgery is a combination of single-port surgery and transanal surgery and was initially developed as a treatment for rectal tumors. Recently, this approach has also been used for more advanced or extended pelvic surgery. METHODS We present a surgical video of combined laparoscopic and transperineal endoscopic total pelvic exenteration performed in a male patient with recurrent rectal cancer and discuss the pros and cons of this approach. RESULTS The operating time was 775 min and the operative blood loss was 485 ml. The pathology was recurrent adenocarcinoma invading the prostate and urethra with negative surgical margins. The postoperative course was uneventful except for a urinary tract infection that was treated with antibiotics. CONCLUSIONS The transanal/perineal endoscopic approach may have some benefits for extended pelvic surgery for recurrent rectal cancer.
