Abstract：
OBJECTIVE: To report the prevalence and risk factors for incisional morbidities in late pregnant and nonpregnant/early pregnant control mares following colic surgery.
METHODS: Multicenter, retrospective, cohort study from January 2014 to December 2019.
METHODS: Two university teaching hospitals and 1 private referral center.
METHODS: Five hundred and seventy-nine fillies and mares ≥2 years old that underwent celiotomy. Pregnant mares (n = 54) were >240 days in gestation from the last known breeding date and were compared to control females (n = 525) undergoing colic surgery.
METHODS: None.
RESULTS: Morbidity rates were not different between mare groups with 56% of pregnant mares and 51% of control mares reporting at least 1 morbidity. Incisional swelling was the most common reported complication in both groups. Incisional swelling was associated with shorter hospital stays (odds ratio [OR], 0.18; P < 0.01), and drainage was associated with a longer hospital stay (OR, 1.27; P ≤ 0.01) and with use of an abdominal bandage (OR, 4.4; P < 0.01). Herniation was associated with hypercapnia under anesthesia (OR, 1.1; P = 0.048), previous abdominal surgery (OR, 8.3; P = 0.003), and with use of an abdominal bandage (OR, 56; P = 0.006). Body wall dehiscence was associated with longer hospital stay (OR, 1.2; P < 0.01). Nonsurvival was higher in pregnant mares (13%) compared to control mares (5%; P = 0.02).
CONCLUSIONS: The prevalence of incisional morbidities did not differ between pregnant and control mares undergoing colic surgery. Several factors were associated with incisional morbidities, including the duration of surgery and anesthesia, anesthetic variables, abdominal bandage use, previous ventral abdominal incision, and longer duration of hospitalization.

摘要：
目的：报告妊娠晚期和非妊娠/早期妊娠对照手术后切口发病率和危险因素。
方法：多中心，回顾性,2014年1月至2019年12月的队列研究。
方法：两所大学教学医院和1个私立转诊中心。
方法：接受开腹手术的五十九只母马和≥2岁的母马。从最后一个已知的繁殖日期开始，妊娠母马（n=54）的妊娠时间>240天，并与接受绞痛手术的对照母马（n=525）进行了比较。
方法：无。
结果：母马组之间的发病率没有差异，56％的妊娠母马和51％的对照母马报告至少有1例发病率。切口肿胀是两组中最常见的并发症。切口肿胀与住院时间较短相关(比值比[OR]，0.18；P<0.01），引流与更长的住院时间(或，1.27;P≤0.01)，并使用腹部绷带(OR，4.4；P<0.01）。疝与麻醉下的高碳酸血症相关(OR，1.1；P=0.048），以前的腹部手术（或，8.3；P=0.003），并使用腹部绷带（或，56；P=0.006）。体壁开裂与住院时间延长有关(或，1.2；P<0.01）。与对照母马（5％；P=0.02）相比，妊娠母马（13％）的非存活率更高。
结论：接受绞痛手术的孕妇和对照组母马的切口发病率没有差异。几个因素与切口发病率有关，包括手术和麻醉的持续时间，麻醉变量，腹部绷带的使用，先前腹侧切口，住院时间更长。
