A 15-year-old adolescent girl diagnosed of interaortocaval paraganglioma with a positive 123I-MIGB SPECT/CT and 1 unsuccessful prior surgery was operated on with the assistance of a handheld gamma camera. Once the lesion was located and removed, 2 images were taken, one of the surgical field (without 123I-MIGB uptake) and another of the tumor ex vivo (with high 123I-MIGB uptake), confirming that the lesion had been satisfactorily excised. This case highlights the use of a portable gamma camera as a useful tool to locate this rare tumor, with a SPECT/CT positive for 123I-MIGB and a difficult anatomical location suspected.

Introduction: after laparoscopic Roux-en-Y gastric bypass (LRYGBP) many patients complain of epigastric pain or food intolerance, leading to the performance of upper gastrointestinal (UGI) endoscopy. Objective: this study aims to assess which symptomatology as reported by LRYGBP patients during follow-up suggested correlation with pathological findings of endoscopy, and which factors might play a role, taking the timing of symptom presentation into account. Materials and methods: a retrospective cohort study was performed identifying LRYGBP patients presenting with food intolerance and/or epigastric pain who had undergone endoscopy.

Background: After Roux-en-Y gastric bypass (RYGB), up to 30% failures in weight loss have been reported. Among multiple solutions available, we report our experience with shortening of the common channel (SCC) by performing a limb distalization of the alimentary or the biliopancreatic limb.

Settings: University Hospital.

Introduction: Bariatric surgery is one of the most common surgical practices in Spain. However, this procedure currently has longest delay on surgical waiting lists (SWL). We have developed a special surgical program that aims to reduce this waiting list and to assess the economic and clinical repercussions in a high-volume bariatric surgery unit.

Introduction: Revisional surgery must be considered when insufficient weight loss is attained or weight is subsequently regained. This study aimed to investigate the value of Roux-en-Y gastric bypass (RYGB) as a revisional procedure after restrictive surgery.

Materials And Methods: An observational, retrospective study including patients initially operated on for morbid obesity with restrictive techniques (vertical-banded gastroplasty [VBG], adjustable gastric band [AGB], and sleeve gastrectomy) and reoperated with RYGB in our centre between December 1994 and January 2019.

Introduction: The aim of this study is to analyze weight evolution after the main bariatric surgical techniques (Roux-en-Y gastric bypass [RYGB] and sleeve gastrectomy [SG]) performed at a representative sample of Spanish hospitals in order to develop percentile charts for the percentage of total weight loss during the first 3 years after surgery.

Methods: A retrospective longitudinal cohort study was conducted based on the data provided by 9 Spanish hospitals. Weight data were analyzed both in % total weight loss and % excess weight lost corresponding to the RYGB (n=1,887) and SG (n=1,210).

Objectives: To evaluate the effectiveness of conversion surgery in a bariatric surgery unit with 25years of experience.

Method: Retrospective observational study of patients with typeII obesity or higher who were reoperated by means of conversion surgery due to weight regain, residual body mass index (BMI)>35kg/m or <50% of excess weight loss. The demographic and anthropometric data, comorbidities and perioperative data were analyzed in 5 periods of time: initial, post-surgery1, pre-surgery2, post-surgery2 and current.

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.

Background: Surgical strategies in patients with BMI > 55 kg/m are not well established.

Objectives: The objective of this study is to compare the long term results and complications of 1- vs. 2-stage laparoscopic "Roux-en-Y″ gastric bypass (LRYGB) for patients with BMI > 55 kg/m.

Background: Complications in sleeve gastrectomy (SG) can cast a shadow over the technique's good results and compromise its safety. The aim of this study is to identify risk factors for complications, and especially those that can potentially be modified to improve safety.

Methods: A retrospective multicenter cohort study was carried out, involving the participation of 29 hospitals.

The rate of choledocholithiasis at the time of elective surgery after mild acute biliary pancreatitis is still unclear because it decreases rapidly after the onset. The aims of this study are as follows: (1) To investigate whether the incidence of choledocholithiasis in mild biliary pancreatitis is higher than in patients with symptomatic cholelithiasis. (2) To evaluate the usefulness of intraoperative cholangiography in the diagnosis of unsuspected choledocholithiasis in mild pancreatitis.
