The authors report a case in which an 87-year-old woman underwent diagnostic laparoscopy for abdominal pain of unknown etiology. Jejunal diverticulosis was discovered with diverticulitis and perforation into the mesentery. Visualization of the appendix, ovaries, uterus, colon, and liver ruled out additional pathology. The disease was serious enough that resection of the involved jejunum was necessary. With the aid of the laparoscope, the incision was directed nearer to the area of the disease. A 5 cm left upper quadrant transverse incision was made, allowing removal of perforation and the diseased bowel. Primary resection and anastomosis were performed. This case sets a precedence for use of exploratory diagnostic laparoscopy and particularly small bowel resection for symptomatic diverticulitis. The authors believe that this technique results in less postoperative pain, allowing for a prompt recovery with minimal morbidity and mortality, particularly in the elderly population.
