BACKGROUND: Robotic assisted pancreaticoduodenectomy (RPD) is reported to be safe and feasible. Internal hernia (IH) after RPD is a serious but rarely reported complication.
MATERIAL AND METHODS: We retrospectively reviewed data of 231 patients who underwent RPD from October 2010 to December 2016. The incidence, symptoms, time of presentation, and outcome were investigated.
RESULTS: Five patients (2.6%) were diagnosed with IH. Significant correlation (P<0.001) between IH and transverse mesocolon defect was confirmed. In patients without defect closure, the incidence of IH was 62.5%, while patients who received defect closure experienced no IH. The median time between initial surgery and occurrence of IH was 76 days. The main symptoms were abdominal pain, nausea, and vomiting. All patients received abdominal computed tomography (CT) and were suspected to have IH according to imaging and symptoms. All patients underwent reoperation (2 laparoscopic and 3 open surgery). The median length of hospital stay was 13 days. No patient experienced a relapse after treatment.
CONCLUSIONS: Abdominal pain, nausea, and vomiting were common symptoms in our study patients who underwent RPD. IH should be suspected if there is a positive finding on CT.

Timely reoperation is necessary because IH may cause intestinal ischemia. Meticulous closure of the mesenteric defect is vital to avoid IH.essary because IH may cause intestinal ischemia.
