Mesenteric rents in the ascending mesocolon as a cause of colic — A retrospective case series
The ventral and dorsal components of the ascending colon are adjoined by the ascending mesocolon, and few case reports have described congenital or acquired malformations of this structure. This case series reports the occurrence of large mesenteric rents of the ascending mesocolon (Hernia mesocolica coli ascendentis) in six adult horses diagnosed during exploratory laparotomy. Based on the history of the patients, the rents were most likely acquired. The rents were mainly located directly adjacent to the left dorsal colon, and without affecting the intestinal blood supply. The size of the defect varied between 20 and 80 cm, and in 5/6 cases it was a subacute or chronic rupture with rounded edges. Two different types of intestinal displacements in relation to the rent were found, with either a localised torsion of the dorsal colon or incarceration of the pelvic flexure in the rent. In all cases, the intestine could be repositioned, and the rent was sutured. Despite some minor postoperative complications, the short- and long-term outcomes were excellent. It was hypothesised that trauma elicited by an intrauterine foal or recurrent colon displacements may have been the cause of the rent in some of the cases.
期刊介绍:
Equine Veterinary Education (EVE) is the official journal of post-graduate education of both the British Equine Veterinary Association (BEVA) and the American Association of Equine Practitioners (AAEP).
Equine Veterinary Education is a monthly, peer-reviewed, subscription-based journal, integrating clinical research papers, review articles and case reports from international sources, covering all aspects of medicine and surgery relating to equids. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of equine medicine and surgery. The educational value of a submitted article is one of the most important criteria that are assessed when deciding whether to accept it for publication. Articles do not necessarily need to contain original or novel information but we welcome submission of this material. The educational value of an article may relate to articles published with it (e.g. a Case Report may not have direct educational value but an associated Clinical Commentary or Review Article published alongside it will enhance the educational value).
