SIGMOIDITEMulticenter Randomized Study Comparing Morbidity and Quality of Life Associated in the Treatment by Surgical Resection and the Conservative Treatment, After Favorable Evolution of Purulent Peritonitis That Originates From Diverticulitis Treated by Mini-invasive Surgery.

Sigmoid diverticular diseases is a pathologie frequent in patients above 60 years old. A person with diverticulosis may have few or no symptoms. When a diverticulum ruptures and infection sets in around the diverticulum the condition is called diverticulitis. An individual suffering from diverticulitis may have abdominal pain, abdominal tenderness, and fever. Bleeding originates from a diverticulum, it is called diverticular bleeding. Frequent hospitalisations as a result of the evolution of purulent peritonitis that originates from diverticulitis treated by mini-invasive surgery results. Radiological percutaneous drainage and washing of the abdominal cavity during laparoscopic generalized purulent peritonitis of diverticular origin have been identified as therapeutic options by HAS (French health authorities), followed by second stage resection-anastomosis under elective surgery. It has been observed in patients that if only drainage and washing are performed (without resection), then the morbidity (10%) and mortality (1.5%) rates are much lower than usual rates (after resection) respectively 20-40% and 10-30%. Furthermore this reduces the risks of postoperatory complications. Some studies have shown that the attitude of non-distance resection of the acute episode was associated with a recurrence rate of diverticulitis less than 5% recurrence without gravity. In addition, the morbidity associated with intervention sigmoid resection is around 30%. The question arises in our daily practice, or not to propose systematic resection of sigmoid diverticulitis after an acute episode of severe purulent peritonitis or abscess types supported initially by minimally invasive. The primary objective of the study is to determine, after clinical improvement linked to conservative treatment of perforated diverticulitis Hinchey peritonitis stage II and III, if a conservative approach reduces morbidity compared with a cold sigmoid resection attitude as currently recommended. The secondary objective of the study is to determine if conservative treatment reduces mortality, length of hospital stay compared with cumulative sigmoid diverticular disease and improves quality of life.
