Is Cystogastrostomy a Definitive Operation for Pancreatitis Associated Pancreatic Fluid Collections?

Area of Science:

• Gastroenterology
• Surgical Oncology
• Pancreatic Diseases

Background:

• Pancreatic-enteric drainage is standard for symptomatic pancreatic pseudocysts and walled-off pancreatic necrosis.
• The necessity of pancreatic resection following recurrence after cyst-enteric drainage is not well-documented.
• This study evaluates recurrence rates and failure predictors after surgical cystogastrostomy.

Purpose of the Study:

• To determine the percentage of patients requiring pancreatic resection due to recurrence after surgical cystogastrostomy.
• To identify predictors of drainage failure in patients undergoing surgical cystogastrostomy.

Main Methods:

• Retrospective review of patients undergoing surgical cystogastrostomy (2012-2020).
• Analysis of demographic, disease, and treatment characteristics.
• Definition of drainage failure as the need for subsequent pancreatic resection due to recurrence.

Main Results:

• 12.5% of patients (3/24) required distal pancreatectomy after initial drainage.
• No significant differences in comorbidities between drainage success and failure groups.
• A trend suggested larger cyst size (15.2 cm) was associated with successful drainage, while smaller cysts (10.3 cm) trended towards failure (P=0.05).

Conclusions:

• Surgical pancreatic drainage is successful for initial management of pancreatic fluid collections.
• No definitive predictors of initial drainage failure were identified.
• Smaller cyst size may be a potential indicator of cystogastrostomy failure, reserving resection for refractory cases.
