Abstract

Purpose: The purpose of this study is to describe modification of the lateral enucleation technique without ligation or clamping of the optic nerve, document the incidence of complications, estimate intraoperative blood loss and identify possible risk factors for the developments of complications.

Methods: Medical records of dogs, cats, and rabbits undergoing lateral enucleation without clamping of the optic nerve were identified and retrospectively reviewed for post-operative complications (2000-2022). The significance of possible risk factors for the development of complications, including species, sex, age, eye, surgeon, presumed ocular surface infection, cultures, follow-up, antibiotics, NSAIDs, complications and diabetes mellitus was examined in a subset of these patients (2019-2022). As a prospective study, intraoperative blood loss was estimated by gravimetric analysis in an additional subset.

Results: Records of 1296 enucleations were retrospectively reviewed and detailed evaluation regarding potential risk factors was performed in 446 enucleations. The overall complication rate and surgical site infection rate was 2.31% and 2.08% respectively. Only Pseudomonas spp. bacterial culture was associated with development of complications. Estimated relative intraoperative blood loss was 2.2% and 4.1% in 43 dogs and 29 cats respectively.

Conclusions: The modified lateral enucleation technique is a safe and fast procedure with minimal risk of postoperative complications in dogs, cats, and rabbits. Based on the anatomy of the orbital vasculature ligation or clamping of the optic nerve and surrounding tissue is contraindicated.

改良的侧切去核术--无需结扎或钳夹视神经的手术:伴侣动物的技术描述、并发症发生率和风险因素以及术中失血量估算。
目的:本研究旨在描述不结扎或夹闭视神经的侧切去核术的改良技术,记录并发症的发生率,估算术中失血量,并确定并发症发生的可能风险因素:方法:对接受不夹闭视神经侧切术的狗、猫和兔的病历进行鉴定,并对术后并发症进行回顾性审查(2000-2022 年)。在这些患者的一个子集(2019-2022 年)中研究了可能导致并发症发生的危险因素,包括物种、性别、年龄、眼睛、外科医生、推测的眼表感染、培养、随访、抗生素、非甾体抗炎药、并发症和糖尿病。作为一项前瞻性研究,还对另外一个子集的术中失血量进行了重力分析估算:回顾性审查了 1296 例去核手术的记录,并对 446 例去核手术的潜在风险因素进行了详细评估。总体并发症发生率和手术部位感染率分别为 2.31% 和 2.08%。只有假单胞菌属细菌培养与并发症的发生有关。43只狗和29只猫的术中相对失血量估计分别为2.2%和4.1%:改良的外侧去核术是一种安全、快速的手术,在狗、猫和兔中术后并发症的风险极低。根据眼眶血管的解剖结构,禁忌结扎或夹闭视神经和周围组织。
