Abstract: Intestinal volvulus complicated with intestinal obstruction is one of acute abdominal diseases in surgery. The
onset and progression of intestinal volvulus are rapid, and most of them are complicated with intestinal blood supply disorder. If not treated in time, intestinal perforation, intestinal necrosis and peritonitis often occur, which seriously endangers the life of patients. There are many cases of intestinal obstruction and necrosis caused by mesentery volvulus, however the lymphatic leakage caused by it is rarely reported. This article reports the diagnosis and treatment of an elderly patient with chylous leakage caused by multiple jejunum diverticulum combined with mesentery volulus and discusses the treatment of chylous leakage caused by small mesentery torsion.

Key words: jejunal diverticulum, mesentery volvulus, chylous leakage
