Adhesion formation after laparoscopic anterior resection in a porcine model: a pilot study.

摘要: Although decreased adhesion formation is one of the accepted advantages laparoscopic colorectal surgery, no prospective studies have been done to support this claim. Therefore, we prospectively assessed following anterior resection rectum in a porcine model. Five domestic female pigs underwent procedure with double-stapled intracorporeal anastomosis. After completion procedure, 50 cm ileum was retrieved through right lower port site. Controlled serosal abrasion antimesenteric surface performed using fresh knife. The abraded loop returned into peritoneal cavity and fascia closed at all sites. All animals midline laparotomy 3 weeks later assess adhesions 0-3 score according density vascularity, extent adhesions. survived study period. mean level anastomosis 8 (range, 7-10) above anal verge; anastomoses were intact completely healed. None had anastomotic site free four animals, only animal (20%) grade 1 between urine horns Conversely, involving 60 40-75) bowel 7 4-9) abdominal wall (remote sites); other noted. In pilot study, small resulted severe However, same associated minimal insignificant Furthermore, unlike incisions, sites did not occur.
