Abstract
Em uma égua, submetida à laparotomia para correção de vólvulo do cólon maior, realizou-se enterectomia próximo ao ligamento cecocólico seguida de enteroanastomose término-terminal. Nas primeiras 24 horas do período pós-operatório, houve piora dos sinais clínicos, com ocorrência de dor, refluxo enterogástrico e agravamento do quadro de endotoxemia. Frente ao prognóstico desfavorável, optou-se pela eutanásia. Durante a necropsia, não foram constatadas falhas na enteroanastomose ou sinais de peritonite séptica. Observou-se encarceramento de uma alça de jejuno, que se apresentava justaposta à extremidade livre da prega cecocólica e comprimida entre o corpo do ceco e o cólon ventral direito remanescente, caracterizando obstrução do tipo estrangulada. Esse achado foi compatível com o agravamento do quadro clínico observado no pós-operatório. Essa ocorrência sugere a necessidade de uma adaptação na técnica de ressecção do cólon maior, de forma a reduzir o espaço cecocólico e evitar um possível encarceramento de alças de intestino delgado.
A mare subjected to laparotomy to treat a large colon volvulus had the large colon transected close to the cecocolic ligament followed by anastomosis using end-to-end technique. Despite intensive care, worsening of the clinical signs occurred during the first 24 hours after surgery including pain, enterogastric reflux and grievance of the endotoxemia symptoms. Euthanasia was performed. During necropsy, no signs of failure of the anastomosis and peritonitis were found but a strangulated segment of jejunum was observed adjacent to the cecocolic fold and compressed by the body of the cecum and the reminiscent rigth ventral colon. This finding was associated with the worsening of the clinical signs during the post-operative period. This report indicates that an adaptation in the large colon resection technique reducing the cecocolic space may be beneficial in avoiding such complication.
