ABSTRACT

Objective To estimate the success rate of emergency endoscopic treatment in patients with esophagogastric variceal bleeding using self-made gastroscope outer casing and to investigate bow to prevent complications. Methods A total of 11 patients with esophagogastric variceal bleeding underwent endoscopic treatment with self-made gastroscope outer casing, which consisted of a wire reinforced plastic casing (1.05 cm in inner diameter, 1.35 cm in outer diameter and 50 cm in length), a 3.8 cm×3.8 cm balloon fixed on the casing head and its cavity connected to the gas pipeline placed in casing tail, an anti-reflux pad in the insert entrance of the endoscope tail as well.as a flushing hole. The endoscopy was introduced to the esophagus or stomch together with outer casing to wash and pump the hematocele out from the side of flushing hole. In patients with hemorrhagic lesion in esophageal vein, the balloon was used to press bleeding vein and intravascular sclerotherapy was performed simutanously. In those with hemorrhagic lesion in gastric vein, the balloon was pressed on esophageal vein near to the cardia and intravascular sclerotherapy was performed. Results During the process of examination, the hemorrhagic lesion was fully exposed because of flushing, and bleeding was controlted in all patients after sclerotherapy. No complication such as aspiration or perforation was seen. Conclusions For emergency endoscopic treatment of esophagogastric variceal bleeding, gastroscope outer casing is helpful in removing intragastric hematocele and maintaining a clear field of vision. It can be effectively improving the efficacy of sclerot herapy.
