Proximal selective vagotomy without pyloroplasty. A randomized clinical study

Area of Science:

• Gastroenterology
• Surgical Research
• Clinical Medicine

Background:

• Duodenal ulcer disease is a common gastrointestinal condition.
• Surgical interventions like vagotomy and pyloroplasty have been used for treatment.
• The necessity of pyloroplasty in conjunction with proximal selective vagotomy requires further investigation.

Purpose of the Study:

• To evaluate the efficacy of proximal selective vagotomy in treating duodenal ulcer disease.
• To determine if the addition of pyloroplasty offers any significant clinical advantage.
• To compare the outcomes of vagotomy with and without pyloroplasty in patients without pyloric stenosis.

Main Methods:

• Elective proximal selective vagotomy was performed on 50 male patients with duodenal ulcers.
• Patients were randomized into two groups: one with pyloroplasty and one without.
• Follow-up included clinical assessment, pentagastrin tests, Hollander tests, and gastrin analysis over 1-3 years.

Main Results:

• No duodenal ulcer recurrences were observed in either group during the 1-3 year follow-up period.
• Only two patients reported major complaints (Visich grade 3).
• No significant differences were found between the vagotomy-only group and the vagotomy with pyloroplasty group across all assessed parameters.

Conclusions:

• Proximal selective vagotomy alone is sufficient for treating duodenal ulcer disease in patients without pyloric stenosis.
• Pyloroplasty is not necessary when performing proximal selective vagotomy, as it does not improve clinical outcomes.
• The study demonstrates that even incomplete vagotomy, as indicated by the Hollander test, can be clinically sufficient.
