Functional results of laparoscopic resection rectopexy for symptomatic rectal intussusception.

PURPOSE: This study was designed to assess the role of laparoscopic resection rectopexy for symptomatic rectal intussusception in patients who failed medical treatment. The functional outcomes of laparoscopic resection rectopexy were evaluated. METHODS: Patients who underwent laparoscopic resection rectopexy for rectal intussusception between July 1998 and November 2004 were identified. All patients with obstructed defecation failing medical treatment were included. Data were prospectively collected for the perioperative period. A follow-up questionnaire was used to assess functional outcome. RESULTS: Between 1998 and 2004, a total of 56 patients (53 females (95 percent); age range, 23-83 years) underwent laparoscopic resection rectopexy for rectal intussusception. The median operative time was 123 minutes. Morbidity was 7 percent, and there was no mortality. Fifty-two patients were available for follow-up, and of these 33 (63 percent) reported an overall improvement in their function after surgery. Of 28 patients suffering constipation, 15 (53 percent) reported an improvement in bowel frequency. Sixty-seven percent of patients incontinent before surgery improved. Symptoms of incomplete evacuation resolved in 38 percent of affected patients. Thirty-six percent of patients needing to strain at stool did not have this problem after surgery. Median follow-up was 44 (range, 15-92) months. CONCLUSIONS: The management of patients with rectal intussusception and obstructed defecation failing medical treatment is challenging. Laparoscopic resection rectopexy is an option that might offer symptomatic relief and improved function. Further studies are required to define the selection criteria to optimize the outcome in this patient group.

Laparoscopically-assisted resection rectopexy for rectal prolapse: ten years' experience.

PURPOSE: This study has been undertaken to audit a single-center experience with laparoscopically-assisted resection rectopexy for full-thickness rectal prolapse. The clinical outcomes and long-term results were evaluated. METHODS: The data were prospectively collected for the duration of the operation, time to passage of flatus postoperatively, hospital stay, morbidity, and mortality. For follow-up, patients received a questionnaire or were contacted. The data were divided into quartiles over the study period, and the differences in operating time and length of hospital stay were tested using the Kruskal-Wallis test. RESULTS: Between March 1992 and October 2003, a total of 117 patients underwent laparoscopic resection rectopexy for rectal prolapse. The median operating time during the first quartile (representing the early experience) was 180 minutes compared with 110 minutes for the fourth quartile (Kruskal-Wallis test for operating time = 35.523, 3 df, P < 0.0001). Overall morbidity was 9 percent (ten patients), with one death (<1 percent). One patient had a ureteric injury requiring conversion. One minor anastomotic leak occurred, necessitating laparoscopic evacuation of a pelvic abscess. Altogether, 77 patients were available for follow-up. The median follow-up was 62 months. Eighty percent of the patients reported alleviation of their symptoms after the operation. Sixty-nine percent of the constipated patients experienced an improvement in bowel frequency. No patient had new or worsening symptoms of constipation after surgery. Two (2.5 percent) patients had full-thickness rectal prolapse recurrence. Mucosal prolapse recurred in 14 (18 percent) patients. Anastomotic dilation was performed for stricture in five (4 percent) patients. CONCLUSIONS: Laparoscopically-assisted resection rectopexy for rectal prolapse provides a favorable functional outcome and low recurrence rate. Shorter operating time is achieved with experience. The minimally invasive technique benefits should be considered when offering rectal prolapse patients a transabdominal approach for repair, and emphasis should now be on advanced training in the laparoscopic approach.
