Enteral feeding patients with gastric outlet obstruction.

Patients with upper gastrointestinal obstructions were previously managed with gastric decompression and parenteral feeding. The authors present their experience in 50 patients with obstructions chiefly due to complicated severe acute (n = 31) or chronic cystic pancreatitis (n = 11) using a double-lumen nasogastric decompression and jejunal feeding tube system (NGJ) held in place with a nasal bridle that passes through the obstructed gastroduodenal segments, allowing distal jejunal feeding, and at the same time decompresses the stomach to prevent vomiting and aspiration. The tip of the jejunal tube was placed approximately 40 cm down the jejunum to maintain pancreatic rest. Duration of feeding ranged from 1-145 days (median 25 days); 19 patients were discharged home with tube feeds. Only 1 patient could not tolerate feeding and needed to be converted to parenteral feeding. Average tube life was 14 days, with replacement being needed most commonly for kinking or clogging of the jejunal tube (56%) or accidental dislodgement (24%). The obstruction resolved spontaneously in 60%, allowing resumption of normal eating. Of the patients with severe acute pancreatitis or pancreatic pseudocysts, pancreatic rest resulted in resolution of the disease without surgery in 87%, and need for surgery in the remainder was put off for 31-76 days. Seven patients died predominantly of complications of acute pancreatitis between 1 and 31 days. In conclusion, NGJ feeding provides a relatively safe conservative management for critically ill patients with upper gastrointestinal obstructions, reducing the need for surgery and parenteral feeding.
