Laparoscopic gastro-jejunal anastomosis using novel r2 deflectable instruments in an ex vivo model.

Objective: A novel 5 mm steerable instrument system (r2-DRIVE) was developed with active tip deflection and tip and shaft rotation. The feasibility and training effect of the r2 instruments were determined in a phantom model.

Material And Methods: Experienced laparoscopic surgeons and untrained novices performed laparoscopic gastro-jejunal anastomoses using porcine tissue and r2 DRIVE-instruments.

Acute and elective laparoscopic resection for complicated sigmoid diverticulitis: clinical and histological outcome.

Background: Surgical treatment of acute complicated sigmoid diverticulitis is still under debate while elective treatment of recurrent diverticulitis has proven benefits. The aim of this study was to evaluate the clinical and histological outcome of acute and elective laparoscopic sigmoid colectomy in patients with diverticulitis.

Methods: A retrospective review was conducted where 197 patients were analyzed undergoing laparoscopic sigmoid resection for acute complicated diverticulitis and recurrent diverticulitis.
