Laparoscopic lavage for perforated diverticulitis in the LapLav study: population-based registry study.

Diverticulitis comprises inflammation in pouches (diverticula) of the large intestine. In the most severe instances, this inflammation can cause perforation of the bowel with purulent or faecal peritonitis. If this happens, surgery is needed. The traditional method has been resection of the inflamed bowel with a stoma. A new technique has been proposed whereby the abdomen is rinsed with saline laparoscopically and a drain is placed (laparoscopic lavage). This study aimed to compare these two methods in terms of clinical short-term outcomes, with a focus on complications. It was found that laparoscopic lavage had fewer complications than resectional surgery and a shorter hospital stay. The new method was safe when used in Swedish routine care.
