Effect on gallbladder function subsequent to truncal vagotomy and gastrojejunostomy for chronic duodenal ulcer.
The effect of truncal vagotomy on gallbladder function and on the incidence of lithogenesis has remained controversial. A prospective and retrospective investigational study was undertaken to evaluate the effect of truncal vagotomy and gastrojejunostomy on gallbladder function. The study included a total of 76 patients and 77 controls. In Group I (Prospective group), 32 consecutive patients with chronic duodenal ulcer and gastric outlet obstruction undergoing truncal vagotomy and gastrojejunostomy were included. Group II included 25 age and gender matched controls (prospective group). Group III included 44 patients who had undergone truncal vagotomy and gastrojejunostomy 3 years or more prior to presentation (Retrospective group) and Group IV included 52 age and gender matched controls for the retrospective group. The patients in the prospective groups were followed up for a period of 1 year. An alkaline tide test was done in the prospective and retrospective group to assess for the completeness of vagotomy. Gallbladder contractile response to fatty meal and the presence of stones and sludge were noted in all the four groups by ultrasonography. There were 30 patients in the prospective group and 40 in the retrospective group after excluding patients with incomplete vagotomy. On ultrasound examination, there was no significant difference in the gallbladder volume and contractility of the study group when compared with the controls. Gallbladder sludge was found in 16 to 25% of patients in the prospective group (group I) during follow up, where as similar finding was documented in 8% of the matched control (group II (P>0.1). However, in the retrospective (group III) 10% (4 out of 40) had calculi and 20% of patients demonstrated sludge which was significantly higher when compared with the controls (p = 0.001). Truncal vagotomy and gastrojejunostomy did not affect gallbladder contractility, but it might predispose to the formation of sludge and subsequent calculi in a proportion of patients in long term.
