To compare the effects of electrodesiccation alone, electrocoagulation alone, and electrocoagulation-electrodesiccation on the efficacy of flat intestinal polyps with diameters of 5-10 mm and the incidence of adverse events.

A total of 221 patients with flat intestinal polyps with a diameter of 5-10 mm who attended the Fourth Medical Center of the Chinese People's Liberation Army General Hospital from March 2021 to March 2023 were prospectively enrolled, and 195 patients were finally included in the study after being screened by inclusion and exclusion criteria, while those who were unwilling to participate in the study and those who withdrew in the middle of the study were excluded. According to the randomized alphabetical method, all the patients were divided into electrodesiccation alone group, electrocoagulation alone group, and electrocoagulation-electrodesiccation group, with 65 patients in each group. The complete resection rate, polyp recurrence rate, operation and hospitalization, recovery time of gastrointestinal function, incidence of adverse events, and patient satisfaction of the three groups were compared.

Postoperatively, the complete resection rate in the electrocoagulation-electrodesiccation group was 96.92%, which was significantly higher than that in the electrodesiccation alone group (81.54%) and the electrocoagulation alone group (84.62%). Although the difference in polyp recurrence rate among the three groups was not significant, the incidence of adverse events in the electrocoagulation-electrodesiccation group was significantly lower than that of the other two groups, which was only 1.54%. In addition, the procedure, recovery and hospitalization times were also significantly shorter in the electrocoagulation-electrodesiccation group than that in the electrodesiccation alone group and electrocoagulation alone group, as well as better in terms of recovery time of gastrointestinal function and higher patient satisfaction.

Compared with electrodesiccation alone or electrocoagulation alone, electrocoagulation-electrodesiccation has better efficacy in the treatment of flat intestinal polyps with a diameter of 5-10 mm, promotes the recovery of gastrointestinal function more quickly, has a low incidence of adverse events, and has a high degree of patient satisfaction.
