Impact of tumor stage and neoadjuvant chemotherapy in fluorescence-guided lymphadenectomy during laparoscopic gastrectomy for gastric cancer: A propensity score-matched study in a western center.

Background: The use of indocyanine green fluorescence has been shown to be a safe and effective method for improving lymph node retrieval in patients with gastric cancer. However, previous studies have focused on early-stage tumors and/or the Asian population and excluded patients who received neoadjuvant treatment.

Methods: In this study, 142 patients with gastric adenocarcinoma underwent laparoscopic gastrectomy at a Spanish hospital between January 2017 and December 2022.

Implanted Closed-Loop Gastric Electrical Stimulation (CLGES) System with Sensor-Based Feedback Safely Limits Weight Regain at 24 Months.

Background: Weight regain following bariatric surgery is not uncommon. Safe, effective weight loss treatment up to 1 year has been reported with the closed-loop gastric electrical stimulation (CLGES) system. Continuous recording of eating and activity behavior by onboard sensors is one of the novel features of this closed-loop electrical stimulation therapy, and may provide improved long-term weight maintenance by enhancing aftercare.

New laparoscopic assisted percutaneous gastrostomy. Description and comparison with others gastrostomy types.

Introduction: Gastrostomy feeding tube insertion has become a common procedure as it enables patients who require long term enteral feeding. Conventional surgical gastrostomies were the only way of gaining enteral access in patients in which it is not possible to pass an endoscope or a nasogastric tube required for endoscopic or radiological gastrostomies, and in patients in which certain anatomical abnormalities contraindicate performing these techniques. As conventional surgical gastrostomies are associated with high morbidity, especially gastric leakage around the tube, percutaneous laparoscopic assisted gastrostomy (PLAG) may be a better way to gain enteral access.

Prognostic factors of weight loss after sleeve gastrectomy: Multi centre study in Spain and Portugal.

Introduction: Sleeve gastrectomy (SG) has become a technique in its own right although a selective or global indication remains controversial. The weight loss data at 5 years are heterogeneous. The aim of the study is to identify possible prognostic factors of insufficient weight loss after SG.

Post-implant Analysis of Epidemiologic and Eating Behavior Data Related to Weight Loss Effectiveness in Obese Patients Treated with Gastric Electrical Stimulation.

Objective: To determine possible preoperative predictors for obtaining clinically meaningful weight loss with gastric electrical stimulation (GES) using the "Three-Factor Eating Questionnaire" (TFEQ) as well as epidemiological data.

Methods: Ninety-seven obese participants in a prospective multicenter randomized study conducted in nine European centers were implanted laparoscopically with the abiliti® closed-loop GES system (CLGES). Five clinical variables and three preoperative TFEQ factor scores (F1-cognitive-restraint, F2-disinhibition, and F3-hunger) were analyzed in order to determine predictors of weight loss success defined as excess weight loss (EWL) > 30% and failure defined as EWL < 20% at 12 months post-surgery.
