Impact of Nasojejunal Feeding on Outcome of Patients with Walled Off Pancreatic Necrosis (WOPN) Presenting with Pain: a Pilot Study.

BACKGROUND

Drainage is usually recommended in symptomatic walled off pancreatic necrosis (WOPN). WOPN presenting with pain may get symptomatic relief if the pancreas is given rest by initiating nasojejunal (NJ) feed.

AIM: The aim of this was to prospectively study the efficacy of nasojejunal (NJ) feeding in patients of WOPN presenting with abdominal pain.

METHODS

Twenty-one patients (15 M; 35 ± 12 years) with WOPN (size 7-16 cm) presenting with pain underwent NJ tube placement under endoscopic guidance. Following this, pain relief and long-term outcome were studied.

RESULTS

Etiology of pancreatitis was alcohol in 12, gall stones in 6, and idiopathic in 3 patients. NJ tube was successfully placed in all patients and 17/21 (81%) patients had symptomatic relief in 1-4 days (mean 2 ± 1 days) following NJ feeding. NJ tube was removed after 7-10 days (mean 7 ± 1 days), and 14 (61%) patients remained pain free and follow-up imaging (1-8 months) revealed complete resolution or decrease in size of WOPN. Three patients had recurrence of pain and were successfully treated with endoscopic drainage.

CONCLUSIONS

NJ feeding improves pain in the majority of patients with WOPN and thus obviates or delays drainage. Majority of nonresponders had disconnected pancreatic duct syndrome (DPDS).
