Development of the "OS-SEV90 Score" to Predict Severe Postoperative Complications at 90 Days Following Bariatric Surgery.

Background: Bariatric surgery may be associated with severe postoperative complications (SPC). Factors associated with the risk of SPC have not been fully investigated.

Objectives: This study aimed to identify preoperative risk factors of SPC within 90 days and to develop a risk prediction model based on these factors.

Does the Implementation of Enhanced Recovery After Surgery (ERAS) Guidelines Improve Outcomes of Bariatric Surgery? A Propensity Score Analysis in 464 Patients.

Background: The aim of this study was to investigate whether the implementation of enhanced recovery after surgery (ERAS) guidelines according to Thorell and co. in our tertiary referral bariatric center might improve post-operative outcomes.

Methods: ERAS program was introduced in our center since January 1, 2017.

Revisional Roux-en-Y Gastric Bypass: a Safe Surgical Opportunity? Results of a Case-Matched Study.

Objective: To evaluate the safety and efficacy of revisional Roux-en-Y gastric bypass (RYGB) after adjustable gastric banding (AGB) or sleeve gastrectomy (SG) compared with primary RYGB, in regard to early and late morbidity, weight, and resolution of obesity-related comorbidities.

Methods: The group of patients undergoing revisional RYGB was matched in a 1:1 ratio with control patient who underwent a primary RYGB, based on age, gender, American Society of Anesthesiologist (ASA) score, preoperative body mass index (BMI), and diabetes mellitus. Demographics, anthropometrics, preoperative work-up, and perioperative data were retrieved.

Esophagopericardial fistula: an unexpected dreaded complication of treatment of leak following revisional sleeve gastrectomy by endoscopic internal drainage.

Esophagopericardial fistula (EPF) is an uncommon but life-threatening complication of upper gastrointestinal tract surgery or endoscopy, which is related to anastomotic breakdown, chronic infection or esophageal traumatism. We first describe the first case of an EPF secondary to double pigtail drain migration: an endoscopic internal approach for the treatment of leak following revisional sleeve gastrectomy.

Impact of neoadjuvant chemoradiotherapy on postoperative outcomes after esophageal cancer resection: results of a European multicenter study.

Objectives: To assess the impact of neoadjuvant chemoradiotherapy (NCRT) on anastomotic leakage (AL) and other postoperative outcomes after esophageal cancer (EC) resection.

Background: Conflicting data have emerged from randomized studies regarding the impact of NCRT on AL.

Methods: Among 2944 consecutive patients operated on for EC between 2000 and 2010 in 30 European centers, patients treated by NCRT after surgery (n=593) were compared with those treated by primary surgery (n=1487).

Indications and mid-term results of conversion from sleeve gastrectomy to Roux-en-Y gastric bypass.

Sleeve gastrectomy (SG) is currently considered as a primary bariatric surgery. This is because of its relative simplicity and satisfactory results. As observed with other bariatric procedures, surgeons are confronted with insufficient weight loss or weight regain, insufficient resolution of metabolic disorders, and intractable severe reflux.
