Introduction

The single anastomosis duodeno-ileostomy with sleeve gastrectomy (SADI-S) was introduced to avoid complications associated with Roux limb construction [1,2,3]. Internal hernias have not been reported with this procedure. This is a case of a Petersen’s internal hernia following primary LSADI-S with its surgical treatment.

Case Presentation

A 54-year-old woman with a BMI of 53 kg/m2 had a primary LSADI-S for morbid obesity. Eighteen months postoperatively, the patient experienced gastroesophageal reflux disease (GERD) and nocturnal regurgitation. An esophagogastroduodenoscopy (EGD) was performed that revealed the presence of bile without hiatal hernia (Fig. 1). The pylorus was wide open, and it seemed that the afferent limb intussuscepted up to the pylorus (Fig. 1). The gastrointestinal series showed that the contrast left the sleeve stomach and went into the afferent limb and dilated it up (Fig. 2). The contrast left the afferent limb, but some went into the stomach and then in the efferent limb [4]. We elected to perform an exploratory laparoscopy for chronic nausea and bile reflux (video).

The EGD demonstrates the presence of bile with no hiatal hernia. Also, it appears as though the small bowel is attempting to intussuscept through the pylorus

The UGI shows a contrast leaving the sleeve stomach, and going into the afferent limb and dilating it up. Small amounts of contrast passed into the efferent limb. b.

At surgery, we discovered a Petersen’s hernia defect, which was corrected by untwisting the bowel and sewing the space closed. We also performed a Braun enteroenterostomy to ensure bile reflux did not occur since the patient had complained of this prior to surgery, and we worried about an incompetent pylorus.

Conclusions

An internal hernia following LSADI-S is rare, despite the unclosed space behind the small bowel mesentery. If they occur, they can be fixed using a laparoscopic surgical approach.
