The Management of 38 Anastomotic Leaks After 1,684 Intestinal Resections

Purpose This study was designed to evaluate the management of anastomotic leaks and assess the impact of outpatient leak presentation on clinical outcome. Methods Thirty-eight patients with clinical anastomotic leaks from 1,684 adult patients undergoing large and small intestinal anastomosis in a tertiary referral center between January 1, 2003 and September 1, 2005 were studied. All pediatric patients and adult patients with esophageal and gastric leaks were excluded. Charts were reviewed for information on anastomotic leak management, discharge status before leak presentation, length of stay, readmissions, and mortality. Results The overall leak rate was 2.3 percent. Eighty-seven percent of patients (n = 33) were managed operatively. Forty-two percent of patients (n = 16) were discharged after initial operation and presented as outpatients with anastomotic leak. The discharge and inpatient groups were comparable in respect to total length of stay (26.9 vs. 33.4 days) and number of readmissions (2 vs. 1.5). The overall mortality of 5 percent (n = 2) originated from the discharge group. A greater percentage of discharge patients required intensive care unit stays for more than two weeks (25 vs. 14 percent) and very long hospital admissions lasting more than two months (31 vs. 9 percent). A smaller percentage of the discharge group patients had their ostomies reversed (31 vs. 50 percent). Conclusions The primary management of clinical anastomotic leak remains intestinal diversion. Although length of stay was shorter in the discharge group, the number of patients who experienced significant intensive care unit stays and very long hospital stays was greater. Within the discharge group, mortality was higher and fewer patients had their ostomies reversed.
