Reconstruction of short bowel syndrome after internal hernia in a pregnant woman with previous bariatric surgery

INTRODUCTIONBariatric surgery is most often performed with the laparoscopic Roux-en-Y gastric bypass. A complication to the laparoscopic Roux-en-Y gastric bypass is internal hernia, which occurs in up to 16% of the patients. Since the laparoscopic Roux-en-Y gastric bypass is performed in women of fertile age, internal hernia may occur during pregnancy.PRESENTATION OF CASEA 22-year old woman with a history of laparoscopic Roux-en-Y gastric bypass suffered from massive internal hernia during pregnancy with widespread bowel necrosis. Extensive surgery was performed leaving the patient with an intact duodenum, 15 cm of jejunum, 35 cm of ileum and colon. Parenteral nutrition was initiated and ten months after the internal hernia, intestinal continuity was re-established. Ten weeks later the patient reached parenteral nutrition independence.DISCUSSIONInternal hernia after laparoscopic Roux-en-Y gastric bypass can be difficult to diagnose, especially during pregnancy and might be severe and life threatening for both mother and child.CONCLUSIONObstetricians and abdominal surgeons must be aware of this condition. Surgery should be performed on a wide indication. When bowel necrosis is found it should be resected and in case of extensive bowel resection the patient should be evaluated in centres specialized in intestinal failure.
