Impact of prior abdominal surgery on curative resection of colon cancer via minilaparotomy

Abstract

To evaluate the impact of prior abdominal surgery on curative resection of colon cancer via a minilaparotomy approach. Feasibility, safety, and oncological outcomes were evaluated retrospectively in 263 patients scheduled to undergo curative resection of colon cancer via a minilaparotomy approach, defined as a skin incision of ≤ 7 cm, between September 2000 and March 2009. Abdominal adhesions were found in 59 (77.6%) of 76 patients who had undergone prior abdominal surgery (PAS group) and in 4 (2.1%) of 187 patients who had not (control group). The success rate of the minilaparotomy approach was 92.1% in the PAS group and 97.3% in the control group (P = 0.08). The incidence of extending the minilaparotomy wound for adhesiolysis was significantly higher in the PAS group than in the control group (6.6% vs 0.5%; P < 0.01). The two groups did not differ significantly in terms of the types of surgery, pathological stage, body mass index, operative time, blood loss, incidence of postoperative complications, length of postoperative hospital stay, and disease-free survival. These results suggest that prior abdominal surgery might require an extension of the minilaparotomy incision but that it does not seem to contraindicate a minilaparotomy approach for curative colectomy.
