A case study of an acute internal hernia: The complex diagnostic challenges of Roux-en-Y gastric bypass complications

Obesity remains a global health challenge linked to several comorbidities, such as obstructive sleep apnea, hypertension, hyperlipidemia, and diabetes. The prevalence of bariatric surgeries being performed is steadily increasing because it is a highly effective surgical tool used to achieve significant permanent weight loss. However, with all weight loss surgeries, several complications may not present for months to years after the initial procedure. In particular, the anatomical changes that occur after the Roux-en-Y gastric bypass (RNYGB) make the risk of internal hernias high. This particular complication is rare but lethal if unrecognized and not treated promptly. This clinical case study aims to provide readers with an overview of diagnosing and recognizing an internal hernia in the setting of previous laparoscopic RNYGB surgical history. Because of the sheer increase in the volume of patients undergoing bariatric surgery worldwide, health care providers must be well educated on the insidious presentations of this late complication and be prepared to act quickly to diagnose and treat these acute abdomen scenarios.
