Robotic-assisted laparoscopic transanal total mesorectal excision for rectal cancer: a prospective pilot study.

Background: We performed a prospective pilot study of robotic-assisted laparoscopic transanal proctectomy with total mesorectal excision for the surgical treatment of rectal cancer. This study was to assess the feasibility and safety of robotic-assisted laparoscopic transanal total mesorectal excision.

Technique: All patients underwent robotic-assisted laparoscopic left colon mobilization, robotic-assisted laparoscopic transanal total mesorectal excision, ultralow mechanical colorectal or handsewn coloanal anastomosis, and a diverting loop ileostomy.

[Transanal endoscopic operations for rectal tumours].

Background: Transanal endoscopic operation (TEO) may be the technique of choice for the treatment of rectal lesions, both benign and selected malignant lesions, with similar survival rates to conventional surgery but with lower morbidity.

Methods: In this article we present a series of 70 patients operated on with this procedure (TEO) in our center. The indications were benign rectal lesions and malignant lesions at early stages (T1) 86%.

[Intraabdominal septic complications in laparoscopic appendectomy: description of a possible new intraabdominal septic complication specific to laparoscopic appendectomy].

Background: Controversies about laparoscopic appendectomy (LA) focus mainly on the high intraabdominal infection rate. In 2005, Serour et al described a distinct complication specific to LA, termed "postlaparoscopic appendectomy complication" (PLAC). This complication is an intraabdominal infection, without abscess formation, which develops after laparoscopic appendectomy for non-complicated appendicitis (simple, phlegmonous, or normal appendix) and is observed in patients discharged after an uneventful postoperative period.
