Total robotic lateral pancreaticojejunostomy and modified Frey's procedure for chronic calcific pancreatitis.

BACKGROUND

Surgical intervention has been shown to have good post-operative outcomes in patients with chronic pancreatitis with pain refractory to oral analgesics. We present our initial experience with robotic lateral pancreaticojejunostomy (LPJ) and modified Frey's procedure (MFP).

METHODOLOGY: Patients with chronic calcific pancreatitis were evaluated with routine biochemical and radiological investigations. The indication of surgery was intractable pain which was recorded by an Intensity Frequency, Consequence (IFC) pain score. The patient was placed in a reverse Trendelenburg position with four 8-mm robotic ports and one 12-mm assistant port. Robotic ultrasound was utilized to identify the pancreatic duct. After retrieving all the calculi, which was confirmed by pancreatoscopy with the help of a video choledochoscope and performing the head coring in particular cases, the Roux-en-Y LPJ was performed.

RESULTS

Among five patients (4 males, one female), robotic LPJ was performed in 2 and MFP in 3 patients. The cohort's median age was 32 (interquartile range (IQR), 28, 40) years, and the median (IQR) pancreatic duct size was 9 (9, 13) mm. The median (IQR) duration of the procedure was 385 (380, 405) minutes, with a median (IQR) blood loss of 100 (50-100) ml, and the patients were discharged on median post-operative day 5. The patients continue to do well at a median follow-up of 3-30 months without the requirement of oral analgesics.

CONCLUSION

Robotic LPJ and MFP are feasible in experienced hands with good post-operative outcomes and enhanced quality of life. Intra-operative pancreatoscopy with the help of a choledochoscope can be utilized to ascertain the complete clearance of pancreatic duct stones and the consequent pain relief.
