Study on the factors influencing the prognosis after perianal abscess surgery

Abstract

Objective To study the influence of clinical characteristics and diagnosis and treatment methods of perianal abscess on postoperative recurrence or formation of anal fistula to provide a basis for selecting appropriate surgical and inspection methods for clinical treatment of perianal abscess in the future. Methods The clinical data of 394 patients with perianal abscesses were collected, the influencing factors were investigated, and univariate analysis and multivariate logistic regression analysis were performed to further determine the risk factors affecting the prognosis of perianal abscess. Results The results showed that the rate of preoperative blood routine results in the uncured group was higher (51.16%) than in the cured group (35.61%); the rate of high abscess space in the uncured group (23.26%) was higher than in the cured group (9.11%); the proportion of patients in the uncured group who underwent magnetic resonance imaging (MRI) before surgery (27.90%) was lower than in the cured group (45.30%); the proportion of patients in the uncured group who underwent simple drainage (51.16%) was higher than in the cured group (28.49%). The two groups had significant differences in perineal MRI examination, surgical method, preoperative blood routine, and abscess space (p = 0.030, p = 0.002, p = 0.047 and p = 0.010, respectively). Based on the results of univariate analysis and multivariate logistic regression analysis, the extent of the abscess cavity (OR = 2.544, 95%CI = 1.087–5.954, p = 0.031) and the surgical method (OR = 2.180, 95%CI = 1.091–4.357, p = 0.027) were independent influencing factors for postoperative recurrence of perianal abscess or anal fistula. Conclusion Preoperative assessment of the abscess range and precise intraoperative methods to resolve the infection of the abscess glands in the internal mouth can effectively improve the cure rate.

Associations of Obesity with the Risk of Anal Fistula: A Mendelian Randomization Study

“…D Wang and G Yang conducted a case-control study and illustrated that obesity was a signi cant risk factor for anal stula 16 . S Dong and B Chen completed an observational study and found that obesity (BMI) was not associated with the occurrence of anal stula after perianal abscess surgery 17 . However, obesity is subject to various confounding factors, including socioeconomic status, dietary patterns, and daily lifestyle habits.…”
