Laparoscopic loop duodenaljejunal bypass with sleeve gastrectomy in type 2 diabetic patientsDiabetes is an epidemic disease and is estimated to affect >300 million people worldwide in 2025 . Type 2 diabetes (T2D) management is a combination of diet, lifestyle modifications, and drug therapy. Recently, many studies have shown remission of T2D in obese population [2–6]. Buchwald et al.  in his systemic review and meta-analysis showed that diabetes remission rates were 99% (95% confidence interval, 97%–100%) after biliopancreatic diversion, 84% (95% confidence interval, 77%–90%) after Roux-en-Y gastric bypass (RYGB), and 48% (95% confidence interval, 29%–67%) after gastric banding.
Hypopharyngeal perforation with mediastinal dissection during orogastric tube placement: a rare complication of bariatric surgeryAlthough currently considered the most successful treatment for morbid obesity, bariatric surgery is associated with certain complications. Placement of an orogastric tube or bougie has resulted in complications because of overstapling or suturing [1,2]. Iatrogenic upper aerodigestive tract perforation, such as hypopharyngeal or esophageal perforation, can occur during endotracheal intubation or esophagogastroduodenoscopy [3,4] and, by contrast, is extremely rare after placement of an orogastric tube or bougie in bariatric surgery [3–8].
