Classification and management of perforations complicating endoscopic sphincterotomy

Area of Science:

• Gastroenterology
• Endoscopic procedures
• Surgical complications

Background:

• Management of perforations after endoscopic sphincterotomy (ES) remains controversial.
• Endoscopic sphincterotomy is a common procedure with a known risk of perforation.
• Understanding perforation types and outcomes is crucial for patient management.

Purpose of the Study:

• To analyze treatment strategies and outcomes for patients experiencing perforations following endoscopic sphincterotomy.
• To differentiate outcomes based on the type and timing of endoscopic sphincterotomy perforations.

Main Methods:

• Retrospective review of 40 patients with endoscopic sphincterotomy perforations identified from 2874 procedures (0.6%) between 1994 and 1998.
• Classification of perforations into guidewire (Group I), periampullary (Group II), and duodenal (Group III).
• Analysis of treatment modalities (medical, endoscopic drainage, surgical) and patient outcomes, including hospital stay and mortality.

Main Results:

• Guidewire perforations (n=14) were recognized early, treated medically, with a mean hospital stay of 3.5 days.
• Periampullary perforations (n=22): 90% treated with endoscopic drainage, no surgery required for early-diagnosed cases. Late diagnosis (2 patients) led to one surgery and death; mean stay 8.5 days.
• Duodenal perforations (n=4): Only 1 early diagnosis; all required surgery, one death; mean stay 19.5 days.

Conclusions:

• Endoscopic sphincterotomy perforations present as three distinct types: guidewire, periampullary, and duodenal.
• Early recognition and medical management are effective for guidewire perforations.
• Aggressive endoscopic drainage is successful for early-diagnosed periampullary perforations, while late-diagnosed duodenal perforations necessitate surgery with significant morbidity and mortality.
