Intraoperative colonic lavage in nonelective surgery for diverticular disease.
BACKGROUND
Staged resection of the sigmoid colon has been the traditional strategy for treating patients who require nonelective surgery to manage complications of diverticular disease. Resection and primary anastomosis has not generally been recommended when the clinical setting is compromised by contiguous inflammation or inadequate mechanical cleansing of the colon because of concerns regarding the potential risk of anastomotic dehiscence. Although many reports have confirmed that intraoperative colonic lavage (ICL) is a safe method for relieving fecal loading of the colon to facilitate primary intestinal anastomosis in patients with mechanical obstruction of the distal colon, there is very limited experience with the use of this technique in treating acute inflammatory disorders of the colon. In this report, we present our results with ICL in the nonelective treatment of patients with complications of diverticulitis.


METHODS
Records of all patients undergoing urgent operations at the Lahey Clinic to treat complications of diverticular disease from July 1987 to January 1996 were reviewed.


RESULTS
Of 62 patients who required nonelective operations, 33 underwent ICL in an attempt to perform primary anastomosis. In five patients, the operation included creation of a colostomy. The indication for surgery was obstruction in 13 patients (39 percent), persistent abscess or phlegmon in 13 (39 percent), perforation in 6 patients (18 percent), and hemorrhage in 1 patient (3 percent). According to Hinchey's classification system, 18 patients had Stage I disease, 10 had Stage II, and 5 patients had Stage III disease. There were no patients with Stage IV disease. The single anastomotic complication in the series was responsible for the sole operative mortality. The morbidity rate of 42 percent, included three intraoperative complications (2 splenic injuries and 1 ureteral laceration), two intra-abdominal abscesses (6 percent), and six wound infections (18 percent).


CONCLUSIONS
In our experience, ICL has proven to be a safe method for accomplishing single-stage resection of the colon in selected patients with diverticulitis who require an urgent operation. When there is no evidence of diffuse purulent or feculent peritonitis, we believe this is the preferred method for treating patients who are hemodynamically stable.
