Can the use of an endoscopic Congo red test decrease the incidence of incomplete proximal gastric vagotomy?

Area of Science:

• Gastroenterology
• Surgical Innovation
• Diagnostic Tools

Background:

• Proximal gastric vagotomy is a surgical procedure to reduce stomach acid production.
• Ensuring complete vagotomy is crucial for surgical success and minimizing complications.
• Postoperative incomplete vagotomy can lead to treatment failure and recurrent symptoms.

Purpose of the Study:

• To evaluate the efficacy of the endoscopic Congo red test in assessing vagotomy completeness.
• To determine if the test can guide intraoperative adjustments to achieve complete vagotomy.
• To assess the feasibility and practicality of the endoscopic Congo red test in a clinical setting.

Main Methods:

• The study involved 44 patients undergoing proximal gastric vagotomy.
• The endoscopic Congo red test was employed to assess vagotomy completeness.
• The test results guided further operative maneuvers when incomplete vagotomy was detected.

Main Results:

• The endoscopic Congo red test identified evidence of incomplete vagotomy in over 95% of patients post-conventional operation.
• Subsequent testing after operative adjustments confirmed the abolition of incomplete vagotomy.
• The test proved to be easily performed, requiring no special equipment and allowing for repeat testing.

Conclusions:

• The endoscopic Congo red test is an accurate and rapid method for evaluating vagotomy completeness.
• The test serves as a valuable intraoperative tool to guide surgical maneuvers and improve outcomes.
• Wider adoption of the endoscopic Congo red test is recommended for verifying complete vagotomy.
