Internal reconstruction of an extended full‐thickness duodenal mesenteric laceration through an antimesenteric duodenotomy in a dog

A 4‐year‐old English setter was presented for acute vomiting secondary to suspected consumption of a foreign body. Unusually extensive full‐thickness lacerations along the mesenteric border of the descending duodenum were present in association with devitalisation of portions of the ascending duodenum. To preserve the duodenum, total duodenectomy with associated biliary tract diversion was not considered. Ascending duodenectomy was performed. The descending duodenal mesenteric lacerations were managed using an internal primary closure technique through an antimesenteric duodenotomy. This particular technique is described, and its potential complications are discussed in this case report. While the outcome of this case report was excellent, more studies are needed before recommending this technique as part of the instrumentarium of duodenal repair.
