Transumbilical single-incision laparoscopic sleeve gastrectomy.

Background: Sleeve gastrectomy has become an established primary bariatric surgical technique. Its relatively lower complexity has made it eligible to be performed by single-incision laparoscopy (single-incision laparoscopic sleeve gastrectomy, SILSG). The aim of this paper is to present our SILSG technique and surgical outcomes and demonstrate that SILSG is a safe and feasible procedure using conventional laparoscopic instruments.

Transumbilical sleeve gastrectomy with an accessory lateral port: surgical results in 237 patients and 1-year follow-up.

Background: The transumbilical approach has recently been shown to be safe for several surgical procedures. Case series of sleeve gastrectomy (SG) with a transumbilical approach (TUSG) has been reported with various techniques. The objective of this report is to present the technique, surgical results, and 1-year follow-up results of simplified TUSG using rigid instruments.

Transumbilical laparoscopic Roux-en-Y gastric bypass with hand-sewn gastrojejunal anastomosis.

Single-port laparoscopic surgery has undergone significant development over the past 5 years. Single port is used in various procedures, including bariatric surgery. The aim of this paper is to describe a surgical technique for gastric bypass with a transumbilical approach (transumbilical gastric bypass-TUGB) with hand-sewn gastrojejunostomy, in selected patients who may be benefited by a better cosmetic result.

Utility of transesophageal echocardiography during severe hypotension in non-cardiac surgery.

Background And Objectives: Severe and refractory hypotension is an infrequent perioperative situation during non-cardiac surgery, but determining its etiology is essential for successful management and therapy.

Methods: Adults undergoing non-cardiac surgery were prospectively enrolled in this study. Severe hypotension was defined as a drop from 30% of baseline systolic arterial pressure unresponsive to adequate fluids administration and to ephedrine, according to the anasthesiologist criteria.

Analgesic effects of a single preoperative dose of pregabalin after laparoscopic sleeve gastrectomy.

Background: The treatment of pain in obese patients is always a challenge. These patients have low pain thresholds, and the use of opioids can be especially harmful. Intraoperative nervous fiber section and the high temperatures of electrical scalpels probably contribute to the generation of postoperative neuropathic pain.
