Abstract


Purpose: The purpose of this study is to compare postoperative complications for single-stage surgery after mechanical bowel preparation in patients who experienced obstruction and those who did not.

Methods: From 2000 to 2011, 1,224 patients underwent a single-stage operation for left colorectal cancer after bowel preparation. Nonobstruction (NOB) and obstruction (OB) colorectal cancer patients were 1,053 (86.0%) and 171 (14.0%), respectively. Postoperative morbidity and mortality were compared between groups.

Results: The OB group had poor preoperative conditions (age, white blood cell, hemoglobin, albumin level, and advanced tumor stage) compared with the NOB group (P < 0.05). Mean on-table lavage time for the OB group was 17.5 minutes (range, 14-60 minutes). Mean operation time for the OB group was statistically longer than that of the NOB group (OB: 210 minutes; range, 120-480 minutes vs. NOB: 180 minutes; range, 60-420 minutes; P < 0.001). Overall morbidity was similar between groups (NOB: 19.7% vs. OB: 23.4%, P = 0.259). Major morbidity was more common in the OB group than in the NOB group, but the difference was without significance (OB: 11.7% vs. NOB: 7.6%, P = 0.070). Postoperative death occurred in 16 patients (1.3%), and death in the OB group (n = 7) was significantly higher than it was in the NOB group (n = 9) (4.1% vs. 0.9%, P = 0.001). Twelve patients had surgical complications, which were the leading cause of postoperative death: postoperative bleeding in five patients and leakage in seven patients.

Conclusion: Postoperative morbidity for a single-stage operation for obstructive left colorectal cancer is comparable to that for NOB, regardless of poor conditions of the patient.
