Background: Extension of a single incision for the purpose of specimen extraction in single-port laparoscopic surgery (SPLS) can undermine the merits of SPLS, either by hurting cosmesis or by increasing wound morbidity.
Methods: We retrospectively analyzed the clinical outcomes of patients undergoing SPLS sigmoidectomy, either with transanal specimen extraction (TASE, n = 15) or transumbilical specimen extraction (TUSE, n = 68), for colorectal cancer between March 2009 and March 2013. The inclusion criterion was a tumor diameter of <= 5 cm. The median follow-up was 93 months (range 13 - 149).
Results: Most of intraoperative and postoperative variables were comparable between the two groups, except for lengthening of operation time in TASE (287 +/- 87 min vs. 226 +/- 78 min, P = 0.011). TUSE did not lengthen the duration of postoperative recovery, hospital stay, or pain, or increase the incidence of postoperative complications. Whereas TUSE showed 8.8% (6/68) of wound-related complications, TASE did not show wound-related complications during follow-up period (P = 0.586).
Conclusion: With the exception of a prolonged operation time, TASE showed equivalent surgical outcomes as TUSE in SPLS sigmoidectomy. Thus, the implement of TASE is expected to provide one way of reducing wound-related complications in SPLS in patients with a tumor diameter of <= 5 cm.
