Although jejunostomy has been considered as a minor procedure by many surgeons, improperly constructed jejunostomy or improper replacement of feeding tube might cause undesired and annoying morbidity. A patient undergoing subtotal gastrectomy with Roux-en-Y reconstruction for perforated peptic ulcer a decade ago was noted to have inoperable esophageal cancer. Feeding jejunostomy was performed for nutritional support. One month later, feeding tube replacement was done for the obstructed, non-functional tube and the course was smooth. Unfortunately, the patient returned days later with prolapse of bowel loop through the stoma of jejunostomy. Despite successful reduction under sedation, the patient suffered a from this unexpected morbidity.
