Background Large bowel obstruction (LBO) after colorectal surgery draws wide differentials. Very few reports of LBO secondary to closed loop mucocele have been published. To our knowledge, LBO due to mucocele of the blind colonic limb of a side-to-end colorectal anastomosis has not been described. Case Details A 57-year-old man presented with pain, gradual abdominal distension and one week history of constipation. He had extensive surgical history – colo-vesical fistula takedown, sigmoid resection and Hartmann type end colostomy followed by reversal, and mesh repair of incisional ventral hernia among others. Notably, a side-to-end configuration was fashioned as a descending colo-rectal anastomosis. CT, followed by MRI scans, of the abdomen and pelvis respectively suggested a mucus-filled short blind colonic bowel segment compressing the anastomotic site as the cause of large bowel obstruction proximal to the site. On flexible sigmoidoscopy under general anaesthesia, external compression of the rectum with narrowing of the lumen was noted. Transrectal needle aspiration of the blind colonic segment yielded 145 mL of mucoid fluid and allowed proximal examination. Anastomotic site was of normal calibre. The patient's symptoms improved and he was discharged with scheduled outpatient follow-up. Gastrografin enema post-discharge demonstrated an end-to-side rectosigmoid anastomosis with local rectal stenosis and showed the blind loop had emptied. Conclusion This case highlights that blind colonic loop mucoceles in colorectal anastomosis can rarely cause obstruction and endoscopic management is feasible when accurate diagnosis is confirmed on imaging.
Aims To conduct a systematic review of the literature to identify the incidence and predictors of incisional hernia (IH) following robotic prostatectomy; and to provide recommendations to reduce the risk factors for IH development post-operatively. Methods The review was performed adhering to PRISMA guidelines, using search terms pertaining to robotic prostatectomy and incidence of IH via electronic databases (MEDLINE, EMBASE and Cochrane database). All original peer-reviewed articles in English were assessed for inclusion and quality by two independent reviewers. A quantitative analysis was conducted to evaluate methodologies, patient demographics, and the incidence of IH following robotic prostatectomy. Results We included 18 studies with a total of 17,965 patients. Average age of patients was 61.83 years and with an average BMI of 27.35. A transperitoneal, 6 port technique was the commonest robotic approach. Main sites of herniation included supraumbilical and lateral ports. The estimated incidence of IH was 1.49% (95% CI 1.28 to 4.25). Studies examining risk factors found age, high BMI, previous hernia repair and wound infections to be contributory to IH development. Only 6 studies reported surgical repair of IH with 3 patients requiring emergency operations. 5 studies reported reduction in IH following modifications in surgical technique. Conclusions Incisional hernias following robotic prostatectomy are a rare complication which can result in high patient morbidity. Our review demonstrated a variable incidence rate with increasing age and high BMI as common potential risk factors. Prevention strategies can result in reduction of IH; however, the studies were heterogenous with inconsistent data quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
