The purpose of this study was to compare success rates for preputial surgery depending on the initial diagnosis, ability to extend the penis, use of sedation and local anesthesia versus general anesthesia for surgery, and surgical technique. Medical records of 51 bulls treated surgically for preputial injury were reviewed. The mean age of the bulls was 2.5 years ranging from 1 to 5 years. Bos taurus breeds (82.3%) were more often affected than Bos indicus breeds (17.7%). The most common breeds represented in this study were Angus (45.1%), Simmental (11.8%), and brangus (9.8%). The seasonal incidence of preputial injuries was higher during the period of May-July (52.9%) and November-February (33.3%). The overall success rate was 70%. Posthioplasty was more successful than circumcision (90% to 43%) (P < 0.05). The success rate for surgeries performed under inhalation anesthesia in the surgery suite was 100% compared with a success rate of 63% for those animals operated on with injectable and local anesthesia in a rotary chute (P < 0.05). The success rate was 88% if the penis could be extended before the surgery and 36% if extension was not achieved (P < 0.05).
本研究的目的是根据初始诊断、阴茎伸展能力、手术中镇静和局部麻醉与全身麻醉的使用情况以及手术技术，比较包皮手术的成功率。回顾了51头接受包皮损伤手术治疗的公牛的病历。公牛的平均年龄为2.5岁，范围在1至5岁之间。瘤牛品种（82.3%）比印度牛品种（17.7%）更常受到影响。本研究中最常见的品种是安格斯牛（45.1%）、西门塔尔牛（11.8%）和婆罗格斯牛（9.8%）。包皮损伤的季节性发病率在5月至7月期间较高（52.9%），在11月至2月期间为33.3%。总体成功率为70%。包皮成形术比包皮环切术更成功（90%对43%）（P<0.05）。在手术套房中采用吸入麻醉进行的手术成功率为100%，而在旋转通道中采用注射麻醉和局部麻醉进行手术的动物成功率为63%（P<0.05）。如果在手术前能够伸展阴茎，成功率为88%；如果无法伸展，则成功率为36%（P<0.05）。
