A multicenter retrospective case-cohort study on the prevalence of incisional morbidities in late pregnant mares following exploratory celiotomy (2014-2019): 579 cases.

Abstract: 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.

This research study investigates the frequency and risk factors of surgical incision complications in late pregnant mares who have undergone abdominal (colic) surgery, comparing them with comparable non-pregnant or early pregnant control horses.

Study Overview

  • The study is a multicenter, retrospective, cohort study, performed from January 2014 to December 2019, involving two university teaching hospitals and a private referral center. It analyzes cases of 579 fillies and mares. Among these mares, 54 were late pregnant(more than 240 days into gestation), and were compared to 525 control mares who also underwent abdominal surgery.

Results

  • The study found that the rates of surgical incision complications were not significantly different between pregnant mares and non-pregnant control mares undergoing colic surgery, with 56% of pregnant mares and 51% of control mares reporting at least one such morbidity.
  • The most common complication reported was incisional swelling, which was linked with shorter hospital stays. In contrast, cases of fluids oozing from the incision were associated with longer hospital stays and the use of abdominal bandages.
  • Hernias were linked with high carbon dioxide levels during anesthesia, previous abdominal surgery, and the use of abdominal bandages. The breaking open of the surgical incision was also associated with longer hospital stays.
  • The study found higher instances of death in pregnant mares (13%) compared to the control mares (5%). This difference was statistically significant.

Conclusions

  • The study concluded that the occurrence of complications from surgical incisions did not vary significantly between pregnant and control mares undergoing abdominal surgery.
  • Several factors significantly increased the chances of surgical incision complications, including the length of surgery and anesthesia, specific anesthetic variables, the use of abdominal bandages, previous ventral abdominal surgery, and an extended duration of hospitalization.
