Hydrostatic anorectal injury caused by fall from jet-ski.

A 14-year-old girl, a rear seat passenger on a jet-ski not wearing suitable protective gear, was 'jumping' waves at a low velocity when she was ejected backwards off the vehicle, suffering a complex and unusual hydrostatic perineal injury as a result of the high-pressure water stream propelling the jet-ski. She presented to the emergency room with rectal bleeding and perineal and abdominal pain. Initial investigations revealed signs of anorectal injury and both intraperitoneal and extraperitoneal free air and fluid, suggesting a possible rectal perforation. Proctoscopy confirmed the primary diagnosis and exploratory laparotomy revealed an intraperitoneal tear in the rectal wall. The tear was repaired, and protective loop colostomy was performed. Initial results of anal manometry, transrectal ultrasound and anal electromyography were unfavourable. However, 17 months after pelvic floor physiotherapy and biofeedback, the colostomy was reversed, and her continence has returned to her normal (preinjury) state.

Unlimited-Length Proctocolectomy Utilizing Sequential Intussusception and Pull-Through: Novel Clean Endolumenal NOTE-Assisted Technique With Transanal Natural Orifice Specimen Extraction Without Rectal Stump Opening in a Porcine Model.

Transanal, hybrid natural orifice translumenal endoscopic surgery (NOTES) and NOTES-assisted natural orifice specimen extraction techniques hold promise as leaders in the field of natural orifice surgery. We report the feasibility of a novel NOTES assisted technique for unlimited length, clean, endolumenal proctocolectomy in a porcine model. This technique is a modification of a transanal intussusception and pull-through procedure recently published by our group. Rectal mobilization was achieved laparoscopically; this was followed by a transanal recto-rectal intussusception and pull-through (IPT). IPT was established in a stepwise fashion. First, the proximal margin of resection was attached laparoscopically to the shaft of the anvil of an end-to-end circular stapler with a ligature around the rectum. Second, this complex was pulled transanally to produce IPT. To achieve an unlimited-length proctocolectomy, the IPT step was repeated several times prior to bowel resection. This was facilitated by removing the ligature applied in the first step of this procedure. Once sequential IPT established the desired length of bowel to be resected, a second ligature was placed around the rectum approximating the proximal and distal resection margins. The specimen was resected and extracted by making a full-thickness incision through the 2 bowel walls. The anastomosis was achieved by deploying the stapler. The technique was found to be feasible. Peritoneal samples, collected after transanal specimen extraction, did not demonstrate bacterial growth. The minimally invasive nature of this evolving technique as well as its aseptic bowel manipulation has the potential to limit the complications associated with abdominal wall incision and surgical site infection.

Repeated transanal endoscopic microsurgery is feasible and safe.

BACKGROUND: The benefits of transanal endoscopic microsurgery (TEM) for the excision of benign and low-grade malignant lesions in the low and middle rectum are well recognized. This study examined the feasibility and safety of a repeated TEM procedure. PATIENTS AND METHODS: Patients who underwent a repeat TEM for excision of rectal lesions, either for involved resection margins or for local recurrence, between the years 2000 and 2010, were identified. Rectal lesion characteristics were retrieved. Mean operative times, length of hospital stay, and intra- and postoperative complications were compared between primary and repeated procedures. The postoperative histopathology reports were reviewed, and the adequacy of resection was determined. All patients completed a questionnaire based on the Wexner score for anal sphincter function evaluation. RESULTS: Fourteen patients (3 female, 11 male) underwent a repeat TEM operation during the study period. All procedures were completed endoscopically. Indications for repeated TEM were involved margins in 12 patients and recurrence of benign tumor in 2. Mean operative time, mean length of hospital stay, and rate of postoperative complications were similar for primary and repeated TEM procedures (62.5 ± 17 versus 55 ± 23 minutes, P=.181; 1.7 ± 1.3 versus 1.7 ± 1.12 days, P=.99; and 35.7% versus 21.4%, P=.66, respectively). The Wexner score was comparable at baseline and after the first and the second TEM procedures (1.5 ± 2.3, 1.5 ± 2.3, and 3.3 ± 3.1, respectively; P=.188). No cases of fecal incontinence following a repeat TEM were documented. CONCLUSIONS: Repeated TEM is feasible and safe and may be appropriate for selected patients.
