Acute abdominal pain due to early postoperative elemental feeding by needle jejunostomy.

Early postlaparotomy needle jejunostomy feeding with an elemental diet resulted in a typical clinical entity in six of 160 patients (4 per cent). In all, an acute condition of the abdomen developed with a grossly distended intestine, filled with fluid and gas, and an empty stomach as confirmed roentgenographically or at a second laparotomy. This complication is presumably caused by carbohydrate hyperosmolarity of the elemental diet and carbon dioxide production by fermentation. The complication was seen predominantly in patients with a Roux-en-Y reconstructed pancreatectomy. In two patients, a negative second laparotomy was performed. In two others, a pancreaticojejunostomy suture line blowout followed, resulting in death. One patient died after aspiration of the gastric contents.
