Multimedia article. Laparoscopic ultralow anterior resection with colonic J-pouch-anal anastomosis.
Optimal treatment of mid to distal rectal cancers includes total mesorectal excision for oncologic clearance and, where reanastomosis is feasible, a colonic J-pouch-anal anastomosis improves bowel function. There is recent interest in performing an ultralow anterior resection laparoscopically. A technique is described that includes specimen extraction through the eventual routine defunctioning colostomy or ileostomy site. ⋯ Laparoscopic ultralow anterior resection could be offered routinely and completed safely in Western populations, where obesity and adhesions from previous abdominal surgery is common. A laparoscopic technique readily allowed visual identification of the autonomic nerves in the abdomen over the aorta, which could then be followed down into the pelvis. If the pelvis was deep, inversion of the 30 degrees laparoscope in the "upside down" position fascilited incision of Waldeyer's fascia. This brought the rectum proximally and anteriorly, aiding with the laparoscopic stapler transection of the distal rectum, especially if the cancer was distal, the patient was obese, and the pelvis was narrow. Extraction of the specimen at the eventual defunctioning stoma site reduced the incisions required. Preoperative chemoradiotherapy may have a role in postoperative male sexual dysfunction. Further randomized, controlled studies that include assessing five-year cancer survival/recurrence, pelvic nerve dysfunction, and bowel function are needed before laparoscopic ultralow anterior resection becomes widely accepted.

Case Reports
Significant rectal bleeding as a complication of a fecal collecting device: report of a case.
We report the case of 65-year-old man who developed massive rectal bleeding associated with the use of a fecal collecting device: the Flexi-Seal Fecal Management System. A colonoscopy showed an acute laceration of the anterior rectal wall mucosa, 6 cm from the anal verge, with active bleeding. ⋯ Massive transfusion was required, and surgical endoscopic treatment was necessary to ensure hemostasis. This is, to our knowledge, the first such case to be reported.

We sought to determine the nature and timing of complications after common anorectal operations by using a prospective quality tracking tool. ⋯ Complications after anorectal procedures are infrequent, typically minor, and occur after hospital discharge. Major complications reflect concomitant illness, not surgical quality. Meaningful outcome measures are needed to assess the quality of anorectal surgery.

The oblique rectus abdominal myocutaneous flap is a seldom used flap design based on perforating vessels exiting the rectus near the umbilicus. Compared to other flaps, the oblique rectus abdominal myocutaneous flap provides increased soft tissue to fill pelvic dead space, with the further advantage of intact skin to close perineal defects. Here we detail the oblique rectus abdominal myocutaneous flap in achieving closure of complex perineal wounds. ⋯ The treatment of complex pelvic wounds, especially following pelvic radiation, is facilitated by the oblique rectus abdominal myocutaneous flap. This technique provides ample tissue for large pelvic wounds, including skin for perineal defects. Comparing our results to existing literature, the oblique rectus abdominal myocutaneous flap displays a favorable morbidity profile, providing a safe means of delivering well-vascularized tissue to the pelvic cavity and perineal floor.

Comparative Study
Temporary sacral nerve stimulation for treatment of irritable bowel syndrome: a pilot study.
This study was designed to evaluate the effect of temporary sacral nerve stimulation in patients with diarrhea-predominant irritable bowel syndrome. ⋯ Temporary sacral nerve stimulation provides a significant reduction in diarrhea-predominant irritable bowel symptoms and improves quality of life. Further studies with permanent implantation and double-blind crossover ON-and-OFF-stimulation to evaluate the impact of placebo effect are needed.
