[Postoperative syndromes and recurrence in highly selective vagotomy]

Area of Science:

• Gastroenterology
• Surgical Research
• Peptic Ulcer Disease

Background:

• Proximal gastric vagotomy (PGV) is a surgical procedure for peptic ulcers.
• Understanding recurrence patterns after PGV is crucial for treatment optimization.
• Different ulcer types may respond differently to PGV.

Purpose of the Study:

• To investigate clinical outcomes and recurrence rates after PGV in various gastroduodenal ulcer types.
• To identify factors contributing to PGV failure in specific ulcer locations.
• To propose an improved surgical strategy for peptic ulcer treatment.

Main Methods:

• Prospective multicenter clinical trial.
• Analysis of clinical results and recurrence data following PGV.
• Comparison of recurrence rates across different gastroduodenal ulcer classifications (duodenal, gastric, pyloric, prepyloric).

Main Results:

• Pyloric and prepyloric ulcers demonstrated a significantly higher recurrence rate post-PGV compared to duodenal and gastric ulcers.
• Secretory patterns did not account for PGV failure in pyloric/prepyloric ulcers.
• Antropyloric dystrophy, an alteration of the muscular layer, is implicated in the failure of PGV for these ulcer types.
• Approximately 60% of recurrent ulcers after PGV were asymptomatic.

Conclusions:

• PGV is less effective for pyloric and prepyloric ulcers, potentially due to underlying antropyloric dystrophy.
• The high rate of asymptomatic recurrences necessitates careful post-operative monitoring.
• A refined surgical treatment concept is proposed to address the limitations of PGV in specific ulcer types.
