Laparoscopic Surgery for Diverticular Disease Complicated by Fistulae

OBJECTIVES: Elective laparoscopic surgery for recurrent, uncomplicated diverticular disease is considered safe and effective; however, little data exist on complicated cases. We investigated laparoscopic sigmoid resection for diver-ticulitis complicated by fistulae. METHODS: We conducted a retrospective review of patients who underwent laparoscopic treatment of enteric fistulae complicating diverticular disease performed by 4 surgeons at the Mount Sinai Medical Center. RESULTS: From 1994 to 2004, 14 patients underwent elective laparoscopic sigmoid resections for diverticular disease complicated by enteric fistulae. Patients’ mean age was 62 and 4 were female. Multiple fistulae were present in 21%. Types of fistulae included 8 colovesical, 5 enterocolic, 2 colovaginal, 1 colosalpingal, and 1 colocutaneous. All patients successfully underwent sigmoidectomy, and 14% required additional bowel resections. No cases were proximally diverted. Conversion to open was necessary in 36% of cases, all due to dense adhesions and severe inflammation. The mean operative time was 209 minutes, and the mean blood loss was 326 mL. Two (14%) postoperative complications occurred, including one anastomotic bleed and one prolonged ileus. No anastomotic leaks or mortalities occurred. The mean postoperative stay was 6 days. CONCLUSION: Laparoscopic management of diverticular disease complicated by fistulae can be performed effectively and safely. The conversion rate is higher than traditionally accepted rates of uncomplicated cases of diver-ticulitis and is associated with severe adhesions and inflammation.
