To report the short-term and long-term outcomes of dogs that underwent the modified closed and traditional closed anal sacculectomy procedures for the treatment of anal sac neoplasia.
90 client-owned dogs.
The medical records of 2 tertiary referral hospitals were reviewed to identify dogs that underwent anal sacculectomy for treatment of anal sac neoplasia between January 2016 and December 2020. Data collected included signalment and preoperative diagnostic findings. The occurrence of intraoperative and postoperative complications, short-term outcomes, and long-term outcomes were also collected. Descriptive statistics were calculated to summarize dog signalment information, and recurrence, metastasis, and survival proportions were compared between techniques using Fisher exact tests.
35 and 55 dogs, respectively, underwent the modified or traditional closed anal sacculectomy procedure. Minor postoperative complications that resolved with minimal intervention occurred in 5 of 35 (14.3%) modified approach dogs and 12 of 55 (21.8%) traditional approach dogs. Tumor recurrence was confirmed in 8 of 35 (22.9%) modified and 8 of 55 (26.4%) traditional approach dogs and was suspected in 3 of 35 (8.6%) and 6 of 55 (13.2%; P = .68), respectively. Confirmed metastatic disease was identified in 8 of 35 (22.9%) and 14 of 53 (26.4%) modified and traditional approach dogs, respectively, and was suspected in 4 of 35 (11.4%) and 7 of 53 (13.2%). Sixty-three (70%) dogs survived to study conclusion.
No benefits in complication rate or local recurrence were identified in dogs following the modified approach as opposed to the traditional closed anal sacculectomy technique.
报告接受改良式封闭与传统封闭肛门囊切除术治疗肛门囊肿瘤的犬的短期和长期疗效。
90 只患犬。
回顾 2 家三级转诊医院的病历，以确定 2016 年 1 月至 2020 年 12 月期间接受肛门囊切除术治疗肛门囊肿瘤的犬。收集的资料包括品种和术前诊断结果。还收集了术中及术后并发症、短期结果和长期结果。使用描述性统计数据对犬的品种信息进行总结，并使用 Fisher 精确检验比较两种技术之间的复发、转移和存活率。
分别有 35 只和 55 只犬接受改良式或传统封闭肛门囊切除术。5 只（14.3%）改良法犬和 12 只（21.8%）传统法犬出现轻微的术后并发症，经轻微干预后痊愈。8 只（22.9%）改良法犬和 8 只（26.4%）传统法犬确认肿瘤复发，3 只（8.6%）和 6 只（13.2%）改良法犬疑似复发（P =.68）。8 只（22.9%）改良法犬和 14 只（26.4%）传统法犬确认发生转移性疾病，4 只（11.4%）和 7 只（13.2%）改良法犬疑似发生转移性疾病。63 只（70%）犬存活至研究结束。
与传统封闭肛门囊切除术相比，改良式手术并未降低并发症发生率或局部复发率。
