“…In the animals whose technical procedure was not observed, the enteric content quickly reaches the large intestine, so the episodes of diarrhea are frequent and intense along with early body weight loss. 4,5,7,8,9,13,14,15,16 Weight loss was common in both groups during the experiment. In animals (G1) with gastrojejunoduodenal interposition, weight was more stable and began to vary at 24 days, with a tendency to stability in the final four intervals.…”

“…It can also be made a correlation to the anastomosis in the pyloric antrum and the second portion of the duodenum, large dynamic sites with respect to gastric juice containing pepsin, rennin, lipase, hydrochloric acid and mucus; duodenal Brünner glands, bile and pancreatic juice; and factors such as hormones and adequate nutrition. 4,5,7,8,17,21,26,27,28,29 . The microbiota also interfered in both the gastrojejunoduodenal and gastrocoloduodenal interposition.…”

“…However, it can lead to changes that are to some extent, irreversible 5,8,14. From this study, it can be considered that jejunal interposition is effective and less complicated than colon interposition. 2,3,7,8 Intestinal interpositions are relevant in several operations on the digestive tract. However, they are not exempt from immediate and long-term complications, and may cause death.…”

“…1,2,7,11,13,14,15,16,21,24,25 The problems that interposition has increasingly presented are overcome by early monitoring of those who will undergo the operation. However, the satisfaction of patients undergoing repair, replacement or creation of an organ with the use of improved techniques using modified functional fabric, is varied.…”

“…In this procedure, disorders are frequent and when intense, can lead the patient into shock or even death. 5,7,8,9,14,16,22,26 In interpositions with partial or total exclusion of the digestive track, segmental bypasses have shown changes in tissue and the pattern of mucus. The modification of the mucosa has been reported in disorders affecting the gastrointestinal tract.…”

-Background -The intestinal interpositions are important in various operations of the digestive tract. However, they are capable to produce serious immediate and late complications. Aim -To compare clinical and surgical outcomes, as well as intestinal pathological findings, in dogs submitted to jejunum and colon interposition. Methods -Forty male mongreal dogs were immunized and dewormed, between 36 and 72 months old and weighting from 6 to 16 kg divided into two groups of 20 (G1=gastrojejunoduodenal and G2=gastrocoloduodenal). They were anesthetized and submitted to laparotomy with jejunum and colon interposition between the gastric antrum and the duodenum. On the 120 th postoperative day, a relaparotomy was performed with removal of the jejunun/colon segments for evaluation. The segments were processed using Bouin and tissue were stained with H&E for histological analysis. Clinical and surgical outcomes analyzed were weight, diarrhea, fistula, infection, suture dehiscence and incisional hernia. The pathological analysis involved neutrophilic infiltration, increase in number of goblet cells and villous and crypts hypotrophy. Mann-Whitney and Fisher Exact tests were used for groups comparisons. Results -Dogs that underwent gastrocoloduodenal interposition had a higher weight loss (p<0.05) and more diarrhea (p<0.001). Clinically, controlled fistula rates were 20% in G1 and 100% in G2. Complications occurred in 20% in G1 and in all animals in G2 (p<0.001). Pathological alterations were also more prevalent in G2 (p<0.001). Conclusion -There is a high morbidity and complication rates involving intestine interposition and higher in G2 where colon segments were used. RESUMO -Racional -As interposições intestinais são importantes em diversasoperações do tubo digestivo. Contudo, são passíveis de complicações imediatas e tardias. Objetivo -Comparar as interposições com segmentos de jejuno e de colo em cães, quanto à evolução clínica e cirúrgica e aspecto anatomopatológico dos segmentos interpostos. Métodos -Foram utilizados 40 cães sem raça definida, imunizados e vermifugados, machos, idade entre 36 e 72 meses, peso entre 6 e 16 kg distribuídos em dois grupos de 20 (G1=gastrojejunoduodenal e G2=gastrocoloduodenal). Submeteram-se à lapatoromia para interposição de jejuno e de colo entre o antro gástrico e o duodeno. Após 120 dias, foi realizada relaparotomia para remoção dos segmentos de jejuno e de colo e analisados pelo método Bouin e cortes histológicos corados por H&E para estudo anatomopatológico. Os resultados clínicos e cirúrgicos analisados foram peso, diarréia, fístulas, infecção, deiscência de sutura e hérnia incisional. A análise patológica envolveu infiltração de neutrófilos, aumento do número de células caliciformes e das vilosidades e hipotrofia de criptas. Os testes de Mann-Whitney e Exato de Fisher foram utilizados na comparação entre os grupos. Resultados -Os cães submetidos à interposição gastrocoloduodenal produziram mais perda de peso (p<0,05) e diarreia (p<0,001). A taxa de fístula clínica fo...
