Safety and long-term outcome of a new concept for surgical adhesion-reduction strategies (Prevadh): a prospective, multicenter study.

Background/aims: No agent has been consistently effective in preventing formation of peritoneal adhesions and postoperative bowel obstruction after abdominal surgery. The aim of this prospective multicenter study was to assess clinical safety and efficiency of a new adhesion-reduction barrier

Methodology: Between September 2000 and April 2001, Prevadh was used in 78 patients. Operative procedures included 25 hepatic resections, 7 cholecystectomies, 32 colonic resections, 7 protectomies, 3 colostomy or recovery of continuity, 1 gynaecologic surgery and 3 others.

Stents for palliation of obstructive metastatic colon cancer: impact on management and chemotherapy administration.

Hypothesis: The more rapid and less complicated recovery after palliative stent insertion compared with surgery may theoretically facilitate the early administration of chemotherapy.

Design: A retrospective study.

Setting: University tertiary care referral center.

Robot-assisted laparoscopic mesh repair of incisional hernias with exclusive intracorporeal suturing: a pilot study.

Background: The da Vinci robot laparoscopic incisional hernia repair with intracorporeal suturing may offer an alternative to transabdominal sutures and tackers.

Methods: From 2003 to 2005, 11 patients (median age, 71 years; median body mass index [BMI], 28) with small and medium-sized incisional hernias (median fascial defect, 19.6 cm2) were treated with the da Vinci robot system using intracorporeal mesh fixation with interrupted sutures.

Povidone-iodine vs sodium hypochlorite enema for mechanical preparation before elective open colonic or rectal resection with primary anastomosis: a multicenter randomized controlled trial.

Hypothesis: The anti-infective actions of povidone-iodine (PVI) and sodium hypochlorite enemas are different.

Design: Prospective, randomized, single-blind study.

Setting: Multicenter.
