Abstract

Background

In laparoscopic upper-gastrointestinal (GI) surgery, an adequate retraction of the liver is crucial. Especially in single-port surgery and obese patients, problems may occur during liver retraction. The current study seeks to evaluate the efficacy and safety of the LiVac trocar-free liver retractor in laparoscopic upper-GI surgery.

One-Anastomosis Jejunal Interposition with Gastric Remnant Resection (Branco-Zorron Switch) for Severe Recurrent Hyperinsulinemic Hypoglycemia after Gastric Bypass for Morbid Obesity

Zorron, R., Branco, A., Sampaio, J. et al. OBES SURG (2016). doi:10.1007/s11695-016-2410-y

Abstract

Background

The anatomical and physiological changes after Roux-en-Y gastric bypass for morbid obesity can lead to severe hyperinsulinemic hypoglycemia with neuroglycopenia in a small percentage of patients. The exact physiologic mechanism is not completely understood. Surgical reversal to the original anatomy and distal or total pancreatectomy are current therapeutic options to reverse the hypoglycemic effect, with substantial associated morbidity. Our group reports a pilot clinical series of a novel surgical technique using one-anastomosis jejunal interposition with gastric remnant resection (Branco-Zorron Switch).

Intraabdominal Trocar-Free Vacuum Liver Retractor for Laparoscopic Sleeve Gastrectomy

Benzing, C., Krenzien, F., Junghans, T. et al. OBES SURG (2016) 26: 1654. doi:10.1007/s11695-016-2245-6

Abstract

Purpose

Retraction of the liver is essential in laparoscopic sleeve gastrectomy. Recently, a new internal liver retractor, the LiVac® device, has been introduced. The current video report (run-time 7:26 min) seeks to demonstrate the efficacy and safety of the LiVac® trocar-free liver retractor in laparoscopic sleeve gastrectomy.

LiVac Study – Germany & Austria

Dr. Philip Gan attended EAES in Amsterdam this week and upon review of the program was pleasantly surprised to find another video session that focused on independent surgeon experience with the LiVac retractor in Germany and Austria.

The study describes the application of the LiVac retractor in over 20 cases, in which the LiVac was used as the sole device for liver retraction across a range of surgical procedures. In all cases the LiVac Retractor System was “easy to apply and provided good exposure of the operative field”.
