Case report: Laparoscopic nissen-sleeve gastrectomy in a young adult with incidental finding of Morgagni-Larrey hernia

Laparoscopic sleeve Gastrectomy (LSG) is the most performed bariatric procedure worldwide but it is associated with an increased incidence of de-novo or recurrent GERD. Recently a new technique consisting in LSG with associated fundoplication has been described. Morgagni-Larrey hernia is very rare and there is a lack of evidences on its correct surgical treatment. There are only rare cases of a MLH incidental diagnosis in patients submitted to bariatric surgery. We present our experience of Morgagni-Larrey Hernia (MLH) incidentally found intraoperatively in a patient with Gastroesophageal Reflux Disease (GERD) with Hiatal Hernia (HH) undergoing a bariatric surgical procedure.

Automated summary

Laparoscopic sleeve Gastrectomy (LSG) is commonly used for weight loss, but it can increase the risk of de-novo or recurrent GERD. A new technique combining LSG with associated fundoplication has recently been introduced. Morgagni-Larrey hernia is rare, and there is limited evidence regarding its surgical treatment. Only a few cases of incidental diagnosis of Morgagni-Larrey hernia in patients undergoing bariatric surgery have been reported. Here, we present a case of incidentally found Morgagni-Larrey hernia during bariatric surgery in a patient with Gastroesophageal Reflux Disease (GERD) and Hiatal Hernia (HH).
