Objective To evaluate the clinical value of endoscopic release therapy for fecal impaction in the colorectal diverticulum. Methods Data of patients with fecal impaction in the colorectal diverticulum who received endoscopy in Shantou Central Hospital from January 2018 to September 2020 were included in this study. Among them, 85 patients treated with endoscopic release therapy were assigned to the observation group (2 patients were excluded from the observation group due to acute appendicitis), and 43 patients receiving no treatment were assigned to the control group. The relief of abdominal symptoms was used as an index to evaluate the clinical value of endoscopic release therapy for fecal impaction in the colorectal diverticulum. Results In the observation group, 42.2% (35/83) were successfully released at one time. The successful comprehensive measures accounted for 25.0% (12/48) of the first release failure, and the total success rate was 56.6% (47/83). There were no complications related to endoscopy in the observation group. One week after the treatment, patients in the observation group were followed up by telephone. Among the 45 patients who were successfully released, positive symptoms of 30 patients disappeared or significantly improved with the effective rate of 90.9% (30/33). Among the 38 patients who failed to release the fecal impaction, 19 had positive symptoms and 16 improved in varying degrees with the effective rate of 55.2% (16/29). The overall effective rate of the observation group was higher than that of the control group [55.4% (46/83) VS 7.0% (3/43)], showing significant difference(χ2=23.354,P<0.01). The effective rate were significant differences in the successful release group [65.2% (30/46)], unsuccessful release group [29.7% (11/37)] and the control group [7.0% (3/43), χ2=33.792,P<0.01]. By pairwise comparison, the effective rate of the successful release group was the highest, followed by the unsuccessful release group, and that of the control group was the lowest with significant difference (P<0.017). Conclusion The endoscopic release therapy for fecal impaction in the colorectal diverticulum is relatively simple, which can relieve and reduce related symptoms, avoid complications, missed diagnosis and misdiagnosis, and show definite curative effects. When colorectal diverticulum with fecal impaction is found in the process of endoscopy, it is of great practical significance to release the incarcerated feces by means of different methods.
