Abstract:
Objective:To analyze the clinical characteristics of long-stalked pedicle polyp(polyp whose pedicle length is larger than width，and a large head >10 mm) of digestive tract,and to compare the effect and safety of removing long-stalked pedicle polyp by ESD and EMR.Methods:The clinical features,endoscopic findings,pathological findings and complications of different treatment methods of long-stalked pedicle polyp in our hospital from January 2021 to December 2022 were retrospectively analyzed.Results:Fifty-seven patients were included in the study,including 24 males and 33 females,and a total of 61 of long-stalked pedicle polyp with an average age of 55.33±14.99 years old.The average head diameter,pedicle length and pedicle width of long-stalked pedicle polyp were （17.30±9.65）mm,（14.16±11.11）mm and（6.30±2.58）mm.85.25% of long-stalked pedicle polyp are found in the colorectum,more commonly in the left half of the colon,accounting for 65.38% of the total colorectal population.In terms of pathological types,adenomatous polyp accounted for 50.82%,hyperplastic polyp 19.67% and traditional serrated adenoma 8.20%.Inflammatory polyp and hyperplastic polyp were the main polyp in the stomach,while adenomatous polyp were more common in the intestine.A total of 2 polyp became cancerous,all in the intestine.The 51 surgical methods were divided into EMR group and ESD group.In the EMR group,with 7 could not evaluate the incisal margin.In the ESD group with 10,all could evaluate the incisal margin well.There was no statistical difference between the two groups in the excision integrity(P>0.05).In terms of adverse events,there was no delayed bleeding in the two groups,and 1 of perforation in the ESD group underwent surgical repair,and there was no statistical difference between the two groups(P>0.05).The mean EMR resection time was (9.08±4.81)min,and the mean ESD resection time was (31.20±10.56)min (including wound closure time),and there was statistical difference between the two groups(P<0.05).Conclusion:As a type of polyp,long-stalked pedicle polyp is more common in the intestine,and the pathological type is mainly adenomatous polyp.As one of the treatment methods of polyp,ESD can achieve overall resection without major complications,especially for large pedicled polyp or suspected cancer.
