Acute Pancreatitis in the Postoperative Course after Esophagectomy: A Major Complication Described in 4 Patients

BACKGROUND: Postoperative pancreatitis is a rare but devastating complication after esophageal surgery. It has been described in connection with abdominal surgery but the etiology in connection with esophageal surgery has never been evaluated. The present study describes 4 cases of postoperative pancreatitis, and a hypothesis about the etiology is formed. METHODS: We performed a search for patients with postoperative pancreatitis after esophagectomy using our prospective database including all patients that underwent esophageal resection at our institution between 1993 and 2008. Pancreatitis was described as abdominal pain, hyperamylasemia, signs of pancreatitis on CT scan or findings during laparotomy or autopsy. RESULTS: A total of 950 patients underwent esophagectomy at our institution, 4 patients developed postoperative pancreatitis (incidence 0.4%). Two out of four patients died. Discussion: Pancreatitis following esophageal surgery is a serious, potentially lethal complication. Diagnosis can be difficult as clear clinical or laboratory findings might be lacking. Peroperative manipulation of the pancreas, mobilization of the duodenum or compromized vascularization have been suggested as etiological factors; although in the described patients, none of these factors were identified as the cause of pancreatitis. In conclusion, pancreatitis following esophageal surgery is a serious but rare complication that should always be considered in patients who deteriorate postoperatively.
