犬人造胃瘘管手术案例分析

目的] 满足犬食道摘除手术,或生理性实验犬的饲喂及采集样品需要,进行试验性犬人造胃瘘管手术。方法] 选取5只中等及大型犬,通过术前准备和检查,并做全身吸入麻醉。在腹底胃区切开皮肤,分离肌肉,拉出胃大弯,在无血管处切开胃壁,放入人造瘘管。对胃壁浆膜肌层进行双层荷包缝合。对腹壁肌肉进行结节对接缝合。术后使用聚维酮碘软膏或油剂注入肌肉与瘘管间隙,加速肉芽形成。手术6个月后对2只犬进行肉芽组织采样做病理切片。结果] 5只犬术后15~25 d创口均取得良好愈合,并可以适应流食饲喂;通过病理学观察发现,肉芽组织生长良好,均为成熟肉芽。结论] 该手术方法可为今后由于病理性原因进行造瘘术和生理实验手术提供实践依据。

Surgical Case Analysis of Canine Artificial Gastric Fistula

Objective]To meet the needs of surgical excision of esophagus,or feeding and sampling of dogs used in physiology experiments,an experimental operation of artificial gastric fistula was performed.Method]Five middle or large dogs were selected for the operation,and general anesthesia by inhalation was performed after preoperative preparation and examination.The abdominal skins in stomach area were cut,the muscular tissues were separated,the greater curvature of stomach was pulled out,the gastric wall was cut in the area without blood vessels,and the artificial gastric fistula was inserted.A double-layer purse-string suture was performed on the serosal muscular layer of gastric wall.The muscular tissues in abdominal wall were sutured tuberously.Povidone iodine ointment or oil was injected into the gap between muscle and fistula to accelerate granulation formation.After 6 months of operation,granulation tissue samples were taken from 2 dogs for preparing pathological section.Result]The wounds of all the 5 experimental dogs healed well and could be fed with the fluid diet 15-25 days after operation.The pathological observation showed that granulation tissues grew well and were mature granulation.Conclusion]This surgical method provides a practical basis for the fistulization of pathological reasons and physiological experiment operation.
