Robotic Totally Extraperitoneal Hernia Repair: An Initial Experience with Cambridge Medical Robotics Versius.

Background: Total extraperitoneal approach for laparoscopic inguinal hernia repair (L-TEP) allows for better dissection, lesser chance of bowel injury, and quicker operating time. However robotic groin hernia repair is currently performed only through transabdominal route as it allows for more mobility of the arms. This study is aimed at studying the feasibility and outcomes of robotic totally extraperitoneal (R-TEP). Methods: A prospective nonrandomized comparative study was conducted to compare R-TEP with L-TEP. Out of a total of 88 patients with inguinal hernia, 44 patients underwent R-TEP and other 44 patients underwent L-TEP over a period of 15 months. All R-TEP were performed with Cambridge Medical Robotics (CMR) Versius. The outcomes were analyzed over a minimum follow-up period of 6 months. Results: All patients were males with a mean age of 45.9 years. Average body mass index was 28.7. Mean docking time for R-TEP was 12.7 minutes. Overall time taken for R-TEP (mean 60.47 minutes) was significantly higher (P < .001) than L-TEP (mean 38.45 minutes). When the console time of R-TEP and overall time of L-TEP were compared, there was no significant difference (P = .053). A RCT (RIVAL Trial) conducted by Prabhu et al. showed their robotic transabdominal preperitoneal (R-TAPP) time of median 75.5 (59.0-93.8) minutes. Kimberly et al. had their overall time of 77.5 minutes and Andre Luiz et al. had a console time of 58 minutes. When we compared the data, the overall time of R-TEP is lesser compared with R-TAPP. Postoperative pain on POD-1 showed that the robotic group had significantly lower pain. There were no recurrences noted in the study period. Conclusion: With our study, we have shown that R-TEP performed using the principle of laparoscopic triangulation technique with CMR Versius is feasible and reproducible. Although the overall time is significantly more in R-TEP when compared with L-TEP, console times of R-TEP and overall times of L-TEP were very similar. Console times of R-TEP are much lesser compared with other studies on R-TAPP. R-TEP can be a better alternative to R-TAPP and can be considered at par with L-TEP. A systematic RCT would provide a better picture.

Laparoscopic posterior rectopexy for complete rectal prolapse: Is it the ideal procedure for males?

Background: Rectal prolapse is more common in elderly women worldwide, but in India, it predominantly occurs in young- and middle-aged males. While ventral mesh rectopexy is proposed as the preferred procedure in females, the debate on the best procedure in men is still wide open. Methods: A retrospective review of all adult male patients operated for external rectal prolapse (ERP) between January 2005 and December 2019 was performed. Patients either underwent modified laparoscopic posterior mesh rectopexy (LPMR) or laparoscopic resection rectopexy (LRR). The outcome was analysed in terms of recurrence, post-operative constipation, sexual dysfunction and other complications. Results: A total of 118 male patients were included (LPMR: 106, LRR: 12). The mean age was 46.2 years (standard deviation [SD] 11.8, range: 21-88). The mean operating time was 108 min (SD: 24). The mean length of hospital stay was 4.8 days (SD: 1.4, range: 3-11 days). There was no anastomotic leak in the LRR group. Other complications included wound infection (n = 2), mesh infection with sigmoid colon perforation (n = 1), constipation (n = 4), sexual dysfunction (n = 2), urinary urgency (n = 3) and retention of urine (n = 4). There was no mortality in both the groups. During a mean follow-up of 5.2 years, recurrent ERP was noted in one patient and partial mucosal prolapse was seen in three patients. Conclusion: LPMR/LRR is a safe and effective treatment for ERP in men with very low recurrence rates. Randomised trials comparing modified LPMR with LVMR are needed to establish the better procedure in males.

Laparoscopic anterior resection: Analysis of technique over 1000 cases.

PURPOSE: Laparoscopic rectal surgery has moved from being experimental to getting established as a mainstream procedure. We aimed at analysing how rectal cancer surgery has evolved at our institute. METHODS: A retrospective review of 1000 consecutive patients who underwent laparoscopic anterior resection for rectal adenocarcinoma over a period of 15 years (January 2005 to December 2019) was performed. Technical modifications were made with splenic flexure mobilisation, intersphincteric dissection and anastomotic technique. The data collected included type of surgery, duration of surgery, conversion to open, anastomotic leak, defunctioning stoma and duration of hospital stay. The first 500 and the next 500 cases were compared. RESULTS: The study patients were predominantly males comprising 68% (n = 680). The mean age of the patients was 58.3 years (range: 28-92 years). Majority of the procedures performed were high anterior resection (n = 402) and low anterior resection (LAR) (n = 341) followed by ultra-LAR (ULAR) (n = 208) and ULAR + colo-anal anastomosis (n = 49). A total of 42 patients who were planned for laparoscopic surgery needed conversion to open procedure. Forty-one patients (4.1%) had an anastomotic leak. The mean duration of stay was 5.3 + 2.8 days. The rate of conversion to open procedure had reduced from 5.4% to 3.0%. The rate of defunctioning stoma had reduced by >50% in the recent group. The anastomotic leak rate had reduced from 5.0% to 3.2%. The average duration of stay had reduced from 5.8 days to 4.9 days. CONCLUSION: This is one of the largest single-centre experiences of laparoscopic anterior resection. We have shown the progressive benefits of an evolving approach to laparoscopic anterior resection.

Modified laparoscopic keyhole plus repair to manage a parastomal hernia: A single-center experience.

INTRODUCTION: Parastomal hernia (PH) is a common late complication of stoma formation for which laparoscopic repair is a well-accepted modality of treatment. Keyhole repair has been frequently reported with recurrence, but our modification in surgical technique have lesser and acceptable recurrence rates. The present study aimed to assess the results of modified laparoscopic keyhole plus repair in the treatment of symptomatic PH. METHODS: We reviewed our prospectively maintained database to search for patients who had undergone laparoscopic modified keyhole repair between January 2008 and April 2018. All 23 symptomatic patients who had undergone this procedure were included in the present study. RESULTS: A total of 23 patients were studied. The median age was 37 years (range, 22-54 years). Two patients with large PHs underwent open excision of the redundant skin and then laparoscopic modified keyhole repair. There was one conversion to open repair because of dense adhesions. The mean operative time was 112 ± 37 minutes. The mean postoperative hospital stay was 3 ± 2 days. There were no significant intraoperative or postoperative complications. During follow-up, three patients had a seroma, which was managed conservatively. One morbidly obese patient who had an ileal conduit-related stomal hernia had a symptomatic recurrence 3 years after surgery. CONCLUSION: The modified laparoscopic keyhole plus repair is a safe, feasible, and effective technique for PH repair; it has an acceptable recurrence rate and offers good cosmesis and functional outcomes.
