Peroral Endoscopic Myotomy in a Patient With Gastric Bypass, a Therapeutic Challenge in the Management of Postoperative Achalasia.

Achalasia is a rare esophageal motor disorder characterized by incomplete relaxation of the lower esophageal sphincter and ineffective contraction of the esophageal body. This condition is not often associated with obesity; however, in recent years, cases of achalasia after bariatric surgery have been described. We describe the case of a 30-year-old female patient with a history of gastric sleeve surgery in 2018, which, 4 years after the intervention, presented with dysphagia, regurgitation, and weight loss.

[E-VAC therapy as treatment of complications in gastrointestinal surgery in a gastroenterology reference center in Colombia: Case series].

Gastrointestinal postoperative anastomotic leaks and fistulas occur frequently and many are managed surgically; however, endoscopic interventions have shown to improve healing outcomes and length of hospital stay. The experience of vacuum-assisted closure therapy (E-VAC) is described, in complications such as fistulas and postoperative anastomotic leaks, in a gastrointestinal reference center in Colombia. A case series study was carried out in patients with anastomotic leaks and fistulas at different levels of the digestive tract, treated by E-VAC, by the Gastroenterology Service in Colombia, during a period from February 2019 to November 2021.

Multimodal Endoscopic Management of Esophageal Perforations as a Complication of Peroral Endoscopic Myotomy for a Zenker's Diverticulum.

Zenker's diverticulum develops because of a weakness in Killian's triangle, leading to a mucosal and submucosal herniation. Its treatment has evolved from morbid surgical interventions to safer endoscopic techniques such as peroral endoscopic myotomy (Z-POEM). Despite being a safe technique, Z-POEM is not free of complications such as perforations, bleeding, pneumoperitoneum, and pneumothorax, for which new endoscopic techniques have been developed.
