Analysis of survival and clinicopathological characteristics in patients after liver resection for colorectal liver metastases according to resection margin.

Background: Criteria for resectability of colorectal liver metastases (CRLM) have been expanded over the last decade along with the improvement in chemotherapy.

Objective: Analyze the differences in several clinicopathological characteristics and overall survival (OS) between patients who underwent an R0 (tumour margin > 1 mm) or R1 (margin < 1 mm) resection.

Method: Retrospective study including 144 patients with CRLM who underwent a potentially curative liver surgery between 2010 and 2018.

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.

Prognostic Factors for Morbimortality in Sleeve Gastrectomy. The Importance of the Learning Curve. A Spanish-Portuguese Multicenter Study.

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.

Metabolic syndrome after bariatric surgery. Results depending on the technique performed.

Background: There is a lack of long-term studies for metabolic syndrome after bariatric surgery. Our aim is to show the evolution of the parameters that define the metabolic syndrome after bariatric surgery, up to 10 years of follow-up, in order to clarify what technique gets better results with fewer complications.

Methods: The IDF definition of the metabolic syndrome was used for this study.

[Prevalence of anal diseases after Scopinaro's biliopancreatic bypass for super-obese patients].

Introduction: Biliopancreatic diversion by Scopinaro (BD) is a mixed (malabsortive and restrictive) bariatric technique that is successful in achieving long lasting weight lost in super obese patients. In fact, the diarrhoea (steatorrhea) that is expected after any malabsortive technique can sometimes cause significant nutritional changes and anal disease: these patients are frequently referred to our coloproctology outpatient clinic due to haemorrhoids, fissures, anal sepsis and fistula basically due to changes in quality and quantity of their faeces. The aim of this paper is to find out not only the prevalence of anal disease in our series of super obese surgical patients but also to compare the incidence between the two surgical techniques we perform in our department.
