Abstract
BACKGROUND: Intestinal resection and a proximal stoma is the preferred surgical approach in patients with severe secondary peritonitis due to perforation of the small intestine. However, proximal stomas may result in significant nutritional problems and long-term parenteral nutrition. This study aimed to assess whether primary anastomosis or suturing of small intestine perforation is feasible and safe using the open abdomen principle with vacuum-assisted abdominal closure (VAC). METHODS: Between January 2005 and June 2018, we performed a retrospective chart review of 20 patients (> 18 years) with diffuse faecal peritonitis caused by small intestinal perforation and treated with primary anastomosis/suturing and subsequent open abdomen with VAC. RESULTS: The median age was 65 years (range: 23-90 years). Twelve patients were female (60%). Simple suturing of the small intestinal perforation was performed in three cases and intestinal resection with primary anastomosis in 17 cases. Four patients (20%) died within 90-days postoperatively. Leakage occurred in five cases (25%), and three patients developed an enteroatmospheric fistula (15%). Thirteen of 16 patients (83%) who survived were discharged without a stoma. The rest had a permanent stoma. CONCLUSIONS: Primary suturing or resection with anastomosis and open abdomen with VAC in small intestinal perforation with severe faecal peritonitis is associated with a high rate of leakage and enteroatmospheric fistula formation. TRIAL REGISTRATION: The study was approved by the Danish Patient Safety Authority (case number 3-3013-1555/1) and the Danish Data Protection Agency (file number 18/28,404). No funding was received.
