Curative Resection of Transverse Colon Cancer via Minilaparotomy

Minilaparotomy has been reported to be a minimally invasive alternative to laparoscopically assisted surgery. We retrospectively evaluated the usefulness of minilaparotomy for the resection of transverse colon cancer, which has generally been considered difficult to resect laparoscopically. Patients for whom curative resection was attempted for transverse colon cancer (n = 21) or sigmoid colon cancer (n = 81) via minilaparotomy (skin incision, ≤ 7cm) were analyzed. The 2 groups did not significantly differ in terms of success rate of minilaparotomy (90.5% versus 97.5%), age, sex, pathologic stage, body mass index, operative time (mean, 133.5 minutes versus 122.5 minutes), blood loss (119.7 mL versus 92.4 mL), number of lymph nodes harvested, incidence of postoperative complications (9.5% versus 12.3%), postoperative length of stay, and 5-year disease-free survival rate (86.6% versus 79.6%). Minilaparotomy is feasible, safe, and favorable in terms of early oncologic outcome in patients with transverse colon cancer as well as those with sigmoid colon cancer.
