Abstract:
Objective:To explore the validity and safety of flat-tipped injection needle and conical catheter these 2 instruments in the hydrodynamic releasing treatment of fecal calculus incarceration in the colonic diverticulum.Methods:From 1 May 2022 to 31 July 2023, 77 patients with fecal calculus incarceration in colonic diverticulum detected by colonscopy at the Endoscope Center of Shantou Central Hospital were prospectively selected. According to the random number table method, 77 patients were randomly divided into the flat-tipped injection needle group (39 cases, 51 fecal stone embedded) and the conical catheter group (38 cases, 49 fecal stone embedded). The successful rate of fecal stone releasing, operation time and complications of 2 groups were observed. Independent samples t test and chi-square test were used for statistical analysis. Results:The successful rate of fecalith releasing of flat-tipped injection needle group was higher than that of the conical catheter group (100.0%, 51/51 vs. 83.7%, 41/49), and the difference was statistically significant ( χ2=9.05, P=0.002). There was no significant difference in the operation time of successful cases between the flat-tipped injection needle group and the conical catheter group ((5.7±1.2) s vs. (5.9±0.8) s, P>0.05). There were no cases of intraoperative or postoperative bleeding or perforation in the process of fecal stone releasing in both groups. Missed submucosal injection occurred in 4 cases of the flat-tipped injection needle group and occurred in three cases of the conical catheter group, and there was no significant difference in the incidence of complications between the 2 groups ( P>0.05). Conclusion:Both instruments are effective and safe in the hydrodynamic releasing treatment of fecal calculus incarceration in the colonic diverticulum, and the success rate of flat-tipped injection needle is higher than that of conical catheter.
