BACKGROUND
With the decreasing number of surgeons on surgical teams, reduced port surgery (RPS) operations have become popular. We herein present our initial experience with RPS, which wasâ€¦ (More)

BACKGROUND
It is unclear whether transumbilical incision for laparoscopic colectomy has a risk of incisional hernia at the extraction site similar to left lower incision.
