Long-term results after low anterior stapled anastomosis.
In the period 01.01.1991-12.31.1996, 286 low anterior stapled resections of the rectum due to rectal carcinoma were performed at the First Surgical Clinic, the Third Department for Colorectal Surgery, Belgrade. There were 57% males and 43% females, median age 59.6 years. The most common localization of tumor was in the distal third of the rectum 181 (63%). In the middle third, there were 89 (31%) and in the upper, intraperitoneal third 16 (6%). Histopathological examination revealed adenocarcinoma in all cases. All operative specimens were examined by one pathologist and classified according to the Gunderson-Sosin modification of Dukes classification. There were 14 (4.9%) in stage A, 167 (58.4%) in stage B (B1,B2,B3), 89 (31.1%) stage C (C1,C2,C3) and 16 (5.6%) stage D. According to Broders classification, there were 129 (45%) well differentiated, 142 (50%) moderately and 15 (5%) poorly differentiated tumors. Anastomotic dehiscence was found in 17 patients (5.95%), mostly conservatively treated, except in 6 cases where spreading peritonitis developed requiring operative treatment. There were 9 (3.1%) postoperative deaths, a half of them with specifically operation related mortality. Recurrence of the disease was registered in 47 (18%) patients, out of 260 who were regularly followed up (26 were lost). Local recurrence alone was found in 21 (8.0%) patients, while distant spread was registered in 22 (8.46%) patients. Local and distant spread was found in 4 (1.5%) cases. At present, the median follow-up is at 54 months. Analysis by the Kaplan-Meier's test shows cumulative survival of 66% at 71 months of the follow-up. Seventy four percent of patients with curative operations exhibit no signs of recurrence at 5 years.
