OBJECTIVE
To compare critically by meta-analysis the postoperative outcomes after truncal vagotomy and pyloroplasty (TVP) and after highly selective vagotomy (HSV).
DATA SOURCES
A search was conducted on MEDLINE with the keywords "peptic ulcer" and "vagotomy". Bibliographics of the articles retrieved and review articles pertaining to the subject were scanned further.
STUDY SELECTION
Included were only published prospective, randomized controlled trials comparing TVP and HSV in the English-language literature up to April 1991. Twelve studies were found.
DATA EXTRACTION
Two authors, working independently, abstracted raw data on mortality, recurrence, dumping, diarrhea and postoperative Visick grading.
DATA SYNTHESIS
A ratio greater than 1.0 indicates a higher proportion occurring with TVP and less than 1.0 a higher proportion with HSV. [Table: See Text]
CONCLUSION
The results suggest that the likelihood of adverse long-term sequelae is higher with TVP whereas the likelihood of recurrence is higher with HSV.
