Long-Term Self-Expandable Metal Stent (SEMS) for Esophageal Variceal Bleeding: A Picture of the Natural History.

Introduction: We aim to discuss the utility of self-expandable esophageal metal stent (SEMS) in variceal bleeding in challenging cases.

Methods: Case description, discussion on patient management and decision-making process in an uncommon situation, from a multidisciplinary point of view.

Results: We report a case of a cirrhotic patient with refractory variceal bleeding who underwent a SEMS placement, which remained in situ for 9 months.

Ambulatory seton placement followed by fistulotomy: efficacy and safety for perianal fistula treatment.

Purpose: To evaluate the efficacy and safety of ambulatory seton placement followed by superficial fistulotomy as treatment of perianal fistula.

Methods: Retrospective observational analysis of patients with cryptogenic perianal fistula aged 18-90 years, followed in a central hospital proctology consultation between 2006 and 2017. Data were obtained through clinical record's analysis.

Endoscopic Treatment of Early Gastric Obstruction After Sleeve Gastrectomy: Report of Two Cases.

Morbid obesity is an epidemic and complex disease which imposes a multidisciplinary approach. Laparoscopic sleeve gastrectomy has become a frequent procedure given its efficacy and safety compared to other surgical options. However, it isn't free from complications.

Endoscopic bilio-duodenal bypass: outcomes of primary and revision efficacy of combined metallic stents in malignant duodenal and biliary obstructions.

Background: Self-expandable metal stents (SEMSs) can be used for palliation of combined malignant biliary and duodenal obstructions. However, the results of the concomitant stent placement for the duration of the patients' lives, as well as the need for and efficacy of endoscopic revision, are unclear.

Aim: This study evaluated the clinical effectiveness of SEMS placement for combined biliary and duodenal obstructions throughout the patients' lives and the need for endoscopic revision.

[Prognostic value of the finding of blood/clots in the stomach at the emergency upper endoscopy].

Introduction: In the setting of upper endoscopy after upper gastrointestinal bleeding (UGIB), the presence of blood or clots in the gastric lumen precluding the complete mucosal examination is a frequent finding.

Aims: To define the prognostic value of this endoscopic finding and the need of a follow-up endoscopy.

Methods: Retrospective study of 100 consecutive patients with UGIB and the endoscopic finding of blood in the stomach (Group A) and 100 at the same conditions but without this endoscopic finding (Group B).
