Avaliação da eficiência da laparotomia pelo flanco para obtenção de biópsias intestinais em equinos

Abstract

Este estudo teve por objetivo avaliar a eficiência da laparotomia pelo flanco para obtenção de biópsias intestinais em equinos, bem como a ocorrência de complicações associadas ao procedimento. Foram utilizados 16 equinos adultos hígidos, sem raça definida, quatro machos e 12 fêmeas, com idade variando entre quatro e 14 anos e peso corporal médio de 248,40 + 2,28 kg. Todos os animais foram submetidos a duas laparotomias pelo flanco para coleta de biopsias intestinais, jejuno e cólon maior, com intervalo de 144 horas entre as coletas. Complicações incisionais foram observadas em 90% dos animais incluindo seroma/infecção da linha incisional e deiscência da linha de sutura. Apesar da ocorrência de complicações, o procedimento demonstrou-se de fácil realização e adequado para obtenção de biopsias intestinais.

Effects of total parenteral nutrition associated with glutamine, enteral fluid therapy, with or without glutamine, and fluid therapy on the lipidogram of horses subjected to starvation after laparotomy

“…Regarding the surgical procedure, no complications were observed in phase 1 of the experiment, except for the development of edema or seroma/infection in the incisional line, regardless of the group, as described by Melo et al (2022a). Protopapas (2000 observed that complications affecting the incision in horses treated surgically for the treatment of gastrointestinal disorders were closely associated with negative energy balance in the horse (Naylor et al, 1980), metabolic alteration invariably associated with absence or low food intake.…”

“…This study was part of a larger experiment developed with the purpose of evaluating the metabolic and gastrointestinal mucosal response of horses subjected to starvation after exploratory laparotomy, and some results were previously published (Melo et al, 2021;2022a, 2022bFerreira et al, 2022;Melo et al, 2022ab). Kidney and liver function parameters remained constant throughout the experimental period, with only fasting hyperbilirubinemia being observed in animals from the ENTFL, ENTGL and PARFL groups.…”

“…Zootec., v.75, n.5, p.807-820, 2023 exteriorization of the large intestine was adopted as a standard procedure, avoiding -if excessive manipulation of the handles. After the collection of intestinal biopsies and entero-anastomosis, the intestinal segment was returned to the abdominal cavity and laparotomy was performed (Melo et al, 2022a). Each laparotomy performed lasted an average of 60 minutes.…”
