Pancreatitis due to afferent loop obstruction.

A 70-year-old woman had undergone laparoscopy-assisted distal gastrectomy with Roux-en-Y anastomosis for gastric cancer four years before being admitted to our hospital complaining of abdominal pain. The laboratory findings showed an elevated serum amylase level and an increased white blood cell count. The serum amylase level was 2,012 IU/L. Computed tomography showed acute pancreatitis caused by afferent loop obstruction (Picture 1-3). She was managed with surgical treatment. The operation revealed an afferent loop obstruction due to an internal hernia. After surgical treatment, the laboratory findings normalized, and her symptoms were resolved. Acute pancreatitis caused by afferent loop obstruction is rare. Afferent obstructions have various causes: malignancy, inflammatory stricture, kinking at the anastomosis, intussusception and internal hernias are known causes (1, 2). If there is a suspicion of acute pancreatitis due to afferent loop obstruction, decompression of the dilated afferent loop is recommended.
