To report intraoperative and immediate postoperative complications associated with removal of metastatic iliosacral lymph nodes in dogs with apocrine gland anal sac adenocarcinoma.
There were 136 client-owned dogs in the study.
Retrospective multi-institutional study. The database of collaborating institutions was searched for dogs with metastatic apocrine gland anal sac adenocarcinoma that underwent lymphadenectomy for removal of one or more iliosacral lymph nodes. Information of signalment, hematological abnormalities, abdominal computed tomography or ultrasound findings, number and size of enlarged lymph nodes, intraoperative and postoperative complications, treatment and outcome were collected.
The overall complication rate associated with metastatic iliosacral lymphadenectomy was 26.1%. The only intraoperative complication recorded was hemorrhage and was reported in 24 (17.6%) surgeries, 11 (45.8%) of which received a blood transfusion. Postoperative complications were reported in 10.4% of surgeries, and included edema formation ( = 4, 2.6%), unilateral or bilateral paraparesis ( = 4, 2.6%), hypotension ( = 3, 2.0%), surgical site infection ( = 2, 1.3%), abdominal incision dehiscence ( = 1, 0.6%), urinary incontinence ( = 1, 0.6%), and death ( = 1, 0.6%). The size of the iliosacral lymph nodes was significantly associated with a greater risk of complications, hemorrhage, and the need of transfusion during lymphadenectomy for metastatic apocrine gland anal sac adenocarcinoma.
Complications associated with iliosacral lymphadenectomy for metastatic apocrine gland anal sac adenocarcinoma are relatively common and mostly relate to hemorrhage. These complications are significantly associated with the size of the extirpated metastatic lymph nodes.
This retrospective study provides information for the clinician regarding the potential surgical complications for extirpation of metastatic iliosacral lymph nodes. These complications, although not common, can be severe and should be discussed with owners before surgery.
报告与犬阿波卡隆氏腺肛门囊腺癌转移性髂骨淋巴结切除相关的术中及术后即刻并发症。
本研究共涉及 136 只患犬。
回顾性多机构研究。对合作机构的数据库进行检索，以寻找患有转移性阿波卡隆氏腺肛门囊腺癌并接受淋巴结切除术以切除一个或多个髂骨淋巴结的犬。收集了有关其一般信息、血液学异常、腹部计算机断层扫描或超声结果、增大淋巴结的数量和大小、术中及术后并发症、治疗和预后的信息。
与转移性髂骨淋巴结切除术相关的总体并发症发生率为 26.1%。唯一记录的术中并发症是出血，在 24 例（17.6%）手术中出现，其中 11 例（45.8%）接受了输血。10.4%的手术出现了术后并发症，包括水肿形成（=4，2.6%）、单侧或双侧后肢轻瘫（=4，2.6%）、低血压（=3，2.0%）、手术部位感染（=2，1.3%）、腹部切口裂开（=1，0.6%）、尿失禁（=1，0.6%）和死亡（=1，0.6%）。髂骨淋巴结的大小与并发症、出血的风险以及淋巴结切除术时输血的需求显著相关，这与转移性阿波卡隆氏腺肛门囊腺癌的淋巴结转移有关。
与转移性阿波卡隆氏腺肛门囊腺癌的髂骨淋巴结切除术相关的并发症相对常见，主要与出血有关。这些并发症与切除的转移性淋巴结的大小显著相关。
本回顾性研究为临床医生提供了关于切除转移性髂骨淋巴结的潜在手术并发症的信息。这些并发症虽然不常见，但可能很严重，应在手术前与主人讨论。
