Miniature surgical robot for laparoendoscopic single-incision colectomy.

Background: This study aimed to demonstrate the effectiveness of using a multifunctional miniature in vivo robotic platform to perform a single-incision colectomy. Standard laparoscopic techniques require multiple ports. A miniature robotic platform to be inserted completely into the peritoneal cavity through a single incision has been designed and built.

Comparison of perioperative outcomes in patients undergoing laparoscopic versus open abdominoperineal resection.

Background: The aim of this study was to retrospectively compare the outcomes of laparoscopic abdominoperineal resection (APR) and open APR.

Methods: A multicenter, retrospective analysis was performed. The University HealthSystem Consortium database was accessed and searched for International Classification of Diseases, Ninth Revision, codes between October 2008 and January 2010.

Miniature in vivo robot for laparoendoscopic single-site surgery.

Background: The aim of this study was to develop a multidexterous robot capable of generating the required forces and speeds to perform surgical tasks intra-abdominally. Current laparoscopic surgical robots are expensive, bulky, and fundamentally constrained by a small entry incision. A new approach to minimally invasive surgery places the robot completely within the patient.
