ABSTRACT
Objective To explore the curative effect of day care unit on the efficacy,safety and satisfaction of elderly patients who underwent a cold snare polypectomy for the treatment colorectal polyps.Methods Clinical data from 454 elderly patients with 824 colorectal polyps(Diameter 4～10 mm)who received a polypectomy from Mar 2020 to Mar 2021 were collected.These patients were classified into three groups.The cold snare polypectomy group and hot snare polypectomy group in day care unit,and the cold snare polypectomy group in general wards.The clinical characteristics,adverse events,recurrence,hospitalization time,and expenses,were compared among three groups.Additionally,the patients'hospitalization satisfaction was investigated and analyzed.Results There were no significant differences in clinical characteristics,histopathology,and rates of postoperative bleeding,perforation,and recurrence among the 3 groups(P＞0.05),but the probability of immediate bleeding was higher in the cold snare polypectomy group.Moreover,coagulation syndrome was unique to the hot snare polypectomy group.The hot snare polypectomy group used the highest amount of endoclips,while the cold snare polypectomy group in the general wards used the least.Furthermore,the hospitalization time and expenses in the day care unit group were significantly lower than in the general wards group.However,the patients'satisfaction survey showed that the day care unit group scored lower than the general wards group(P＜0.05).Conclusions It is safe,cost-effective and effective for elderly patients with colorectal polyps using cold snare polypectomy technique under the day care unit mode,but the lack of communication with the patient's condition in a short period of time rather leads to a decrease in hospital satisfaction.
