Single-incision laparoscopic surgery for cholecystectomy: a retrospective comparison with 4-port laparoscopic cholecystectomy.

Objectives: To report our experience with single-incision laparoscopic surgery (SILS) for cholecystectomy and to perform a retrospective comparison with conventional 4-port laparoscopic cholecystectomy.

Design, Setting, And Patients: Data were prospectively collected for all patients undergoing SILS for cholecystectomy at St Mary's Hospital, Imperial College NHS Trust, London, England (n = 41 patients between June 13, 2008, and June 30, 2009) and compared with data for those who had undergone conventional 4-port laparoscopic cholecystectomy in the preceding year (n = 58 patients between June 26, 2007, and May 30, 2008). This included patient demographic data and intraoperative and postoperative outcomes.

Secondary chronic venous disease progresses faster than primary.

Purpose: To compare the progression rate of primary with secondary chronic venous disease (CVD).

Methods: Patients with a first episode of proximal deep vein thrombosis (DVT), diagnosed by duplex ultrasound (DU) were included in group A - secondary CVD (41 patients, 46 limbs). DU was performed at least once, 1 year after the diagnosis, and repeated at 5 years.
