Truncal vagotomy has been related to an enlargement of the resting volume and impaired contraction of the gallbladder, and an increased incidence of cholelithiasis, changes that are not reported in selective or highly selective vagotomy. We studied 12 patients, 7 with truncal vagotomy, 2 with selective, 1 with highly selective and 1 patient with subtotal gastrectomy alone. We measured the gallbladder volume and contraction sonographically and compared them with normal values. The patients with truncal vagotomy had an increased resting volume and an impaired gallbladder contraction. The patients with selective vagotomy had a normal resting volume but a decreased gallbladder contraction. We also found cholelithiasis in 2 of our patients with truncal vagotomy, for an incidence of 28%, similar to the ones reported by other authors.
迷走神经干切断术与胆囊静息容量增大、收缩功能受损以及胆结石发病率增加有关，而选择性或高选择性迷走神经切断术则未报告有这些变化。我们研究了12例患者，其中7例行迷走神经干切断术，2例行选择性迷走神经切断术，1例行高选择性迷走神经切断术，1例仅行胃次全切除术。我们通过超声测量了胆囊容积和收缩情况，并与正常值进行比较。行迷走神经干切断术的患者静息容量增加，胆囊收缩功能受损。行选择性迷走神经切断术的患者静息容量正常，但胆囊收缩功能下降。我们还在2例迷走神经干切断术患者中发现了胆结石，发病率为28%，与其他作者报告的发病率相似。
