Background: With the aim of resolving the current controversy over the diagnosis and treatment of diverticular disease, this consensus development conference set out to summarize the actual state of the art. Methods: A multidisciplinary panel of international experts (n= 16) was selected to take part in the consensus process. Prior to the conference, all experts were asked to answer a series of questions on diverticular disease. The consensus statement compiled out of these evaluations was modified during a joint meeting of the panel members, then presented for discussion in a public session, and finally revised by the expert panel. The finalized statement was mailed to all panel members for approval (Delphi method). Results: Asymptomatic diverticulosis, diverticular disease (with actual or recurrent symptoms), and complicated diverticular disease were defined separately. No agreement was reached on whether barium enema or colonoscopy is the better choice as an initial diagnostic tool in uncomplicated cases. In complicated cases, computed tomography is recommended for diagnosis. After two attacks of diverticular disease, elective resection should be considered. For patients in whom a concomitant carcinoma cannot be excluded and those with chronic complications (fistula, stenosis, or bleeding) surgery is also indicated. Laparoscopic sigmoid colectomy is recommended only for uncomplicated and, after percutaneous drainage of abscesses, Hinchey stage I and II cases. Conclusions: Laparoscopic surgery has already begun to influence the management of diverticular disease, but the randomized controlled trials needed to support therapy decisions are largely missing.

Background: Resection of diverticular disease may be quite challenging; the acute inflammatory process, thick sigmoid mesentery, and any associated fistula or abscess can make this procedure technically demanding. The aim of this study was to compare the results between laparoscopic and laparotomy-type resections stratified by disease severity and thereby predict outcome and possibly a subset of patients who may benefit from a laparoscopic approach. Methods: From August 1991 to December 1995, all patients with diverticular disease were classified according to a modified Hinchey classification system. The laparoscopic group included 18 patients who underwent a laparoscopic assisted colectomy, one with a loop ileostomy. The identical procedures were performed in 18 patients by laparotomy. The mean age of the two groups were 62.8 and 67.1 years, respectively (p= NS). Results: Seven of 18 patients in whom laparoscopy was attempted (38.9%) had conversion to laparotomy. Six of seven (85.7%) conversions were directly related to the intense inflammatory process. Laparoscopic treated patients with Hinchey IIa or IIb disease had a morbidity rate of 33.3% and a conversion rate of 50% while all patients with Hinchey I disease were successfully completed without morbidity or conversions to laparotomy. However, after the first four cases, the intraoperative morbidity and postoperative morbidity rates were zero and 14.3% and after ten cases they were zero and zero, respectively. Furthermore, the median length of hospitalization for Hinchey I patients after laparoscopy was 5.0 days vs 7 days after laparotomy (p < 0.05). In Hinchey IIa and IIb patients, the median length of hospitalization was almost 50% shorter with a laparoscopic approach (6 days vs 10 days, p < 0.05). Conclusion: In conclusion, laparoscopic resection of diverticulitis can be performed without additional morbidity particularly in Hinchey I patients and with a reduced length of hospitalization in patients with class I or II disease. Patients with class I disease, and after initial experience even those with class II disease, can benefit from the reduced morbidity and length of hospitalization associated with laparoscopic treatment.

This study was designed to compare laparoscopic peritoneal lavage and drainage (LLD) with laparoscopic Hartmann’s procedure (LHP) in the management of perforated diverticulitis and to investigate a safer and more effective laparoscopic method for managing acute perforated diverticulitis with generalized peritonitis. A consecutive series of patients who underwent emergent LHP or LLD for perforated diverticulitis were identified from a prospectively designed database. All procedure-related information was collected and analyzed. P
