Abstract
The objectives of this study were to refine the technique of laparoscopically assisted anterior resection (LAR) for diverticular disease and to analyze the morbidity and mortality rates, and longer term follow-up of the first 100 consecutive patients. Data were collected prospectively, and follow-up was performed by an independent assessor using a standardized questionnaire. The median duration of surgery was 180 minutes, the median time for passage of flatus was 2 days after surgery, and the median length of hospital stay was 4 days. Overall, the morbidity rate was 21%, and the wound infection rate was 5%. There were no deaths. Eight patients underwent open laparotomy. The rate of complications was significantly greater in the latter group of patients (75%) than in those who underwent laparoscopy (16%, p = 0.002). The comparison between the first 20 cases and the last 20 patients revealed a significantly shorter duration of surgery (median 225 min. vs. 150 min.; p < 0.0001) and decreased length of stay (6 days vs. 4 days, p < 0.0001). Apart from a nonsignificant increase in the length of surgery, there were no differences in other study parameters when comparisons were made between those patients who underwent LAR for complicated diverticular disease and those patients who underwent uncomplicated diverticular disease. Ninety patients were available for follow-up at a median time of 37 months. Ninety-three percent of the patients reported that the surgery had improved their symptoms. No patient required hospitalization, and no one was treated with antibiotics for recurrent symptoms. Laparoscopically assisted anterior resection for diverticular disease has acceptable morbidity and mortality rates and a median postoperative hospital stay of only 4 days. Follow-up investigations revealed no recurrence of diverticulitis, and patients reported satisfaction regarding cosmetic and functional results.
