Primary Mechanical Stapled Anastomosis in Surgery for Colorectal Emergencies

From May 91 to March 99 a consecutive series of 100 acute obstructions or perforations of the left colon or rectum were treated by primary resection with mechanical anastomosis using a double or triple stapling technique without proximal colostomy. There were 8 postoperative deaths (8%) due to sepsis, acute respiratory distress syndrome, pulmonary embolism, stroke, and cachexy. Complications occurred in 29% of surviving patients. Clinical anastomotic leaks were observed in 7%, respiratory infection in 8%, wound infection in 8% and major cardiovascular problems in 4% of patients. The median hospital stay was 19 days. The morbidity and mortality of this series did not exceed the cumulative morbidity and mortality that can be expected after staged surgery. Compared with staged surgery, immediate resection and anastomosis using an entirely mechanical suture, thereby avoiding the problems of colostomy and reducing the length of hospital stay, has significant advantages for patients.
