Abstract:
Objective:To evaluate the value of endoscopic cutting transnal local resection stapler in the treatment of middle and low rectal tumors.Methods:Twenty-four patients with middle and low rectal tumors were included in this study.They underwent transanal local resection of rectal tumors with endoscopic cutting stapler,to summarize and analyze the clinical and pathological data and imaging diagnosis of the patients,and to observe the safety and feasibility of the operation.Results:14 of the 24 patients were positive for occult blood in stool.The main symptoms were hematochezia.The tumor was mainly located in the anterior wall.With the increase of tumor diameter,the diagnostic accuracy of enhanced CT,MRI and EUS also increased.The accuracy of the combined evaluation of enhanced CT,MRI and EUS was higher than that of the three evaluation results alone.The postoperative pathological results showed that 4 cases were subepithelial tumors,3 cases were located in the submucosa and 1 case was located in the musculi propria.In the 20 of cases epithelial tumors,9 cases were benign tumors of epithelial origin,which were low grade tubular adenomas or low grade mixed adenomas,2 cases of high-grade intraepithelial neoplasia.9 cases of rectal cancer,including 1 case of mucosa invasion,3 cases of submucosa invasion,4 cases of muscle invasion,and 1 case of whole layer invasion.In 24 cases,the complete resection rate was 100%,and the complete operation rate was 100%.No conversion to laparoscopy or laparotomy was performed.The mean time of operation,mean blood loss,mean time of first exhaust and mean days of hospitalization were (29.25±6.42)min,(15.04±4.12)mL,(35.38±5.94)h,(3.17±0.92)day,respectively.WBC reactivity was increased in 7 patients after operation and recovered to normal at 2~4 days after operation.RBC and HGB counts were decreased in all patients,but they were in the normal range,all patients had no postoperative complications.Conclusion:Transanal resection of middle and low rectal tumor with endoscopic cutting stapler has the advantages of short operation time,less side-injury,low stress reaction and quick recovery.This method has a wide range of clinical application prospects.
