To identify risk factors for recurrence and surgical site infection (SSI) after perineal hernia repair surgery in dogs.
Medical records of male dogs undergoing perineal herniorrhaphy from 2008 to 2023 at a single institution were retrospectively reviewed. Data pertinent to patient signalment, surgical repair methods, risk factors for SSI, and risk factors for recurrence were collected. Follow-up was obtained via referring veterinarian records and/or owner interviews. Dogs without 12 months of postoperative follow-up were excluded. Statistical analysis was performed with descriptive statistics and compared between groups by use of a combination of univariable analyses.
84 dogs were included in this study. Recurrence occurred in 13 cases (15%), and SSIs occurred in 6 cases (7%). Dogs neutered prior to surgical correction of a perineal hernia were 4.4 times as likely to have a recurrence of the hernia after surgery compared to dogs neutered at time of surgical correction, and dogs that developed fecal incontinence postoperatively were 3.4 times as likely to have a recurrence. There were no other significant associations between perineal hernia recurrence or the development of SSIs and the associated risk factors evaluated.
No risk factors for the development of SSI could be identified in this group. Dogs neutered prior to perineal herniorrhaphy compared to dogs neutered at time of surgical correction as well as dogs that developed fecal incontinence postoperatively may have both been at increased risk for recurrence after surgical hernia correction.
Owners of dogs undergoing perineal herniorrhaphy after a prior castration should be educated on the possible increased risk of hernia recurrence postoperatively, and owners of dogs that develop fecal incontinence postoperatively should be informed of the possible increased risk for hernia recurrence.
确定犬会阴疝修补术后复发及手术部位感染（SSI）的风险因素。
回顾性分析2008年至2023年在单一机构接受会阴疝修补术的雄性犬的病历。收集与患犬特征、手术修复方法、SSI风险因素及复发风险因素相关的数据。通过转诊兽医记录和/或主人访谈进行随访。未进行术后12个月随访的犬被排除。采用描述性统计进行统计分析，并通过单变量分析组合在组间进行比较。
本研究纳入84只犬。13例（15%）出现复发，6例（7%）发生SSI。与手术矫正时绝育的犬相比，会阴疝手术矫正前绝育的犬术后疝复发的可能性高4.4倍，术后出现大便失禁的犬复发可能性高3.4倍。会阴疝复发或SSI的发生与评估的相关风险因素之间无其他显著关联。
该组中未发现SSI发生的风险因素。与会阴疝修补术时绝育的犬相比，会阴疝修补术前绝育的犬以及术后出现大便失禁的犬在手术疝修补术后复发风险可能均增加。
应对先前已绝育后接受会阴疝修补术的犬主人进行术后疝复发风险可能增加的教育，对于术后出现大便失禁的犬主人，应告知其疝复发风险可能增加。
