Epidemiological profile of patients with fistula in ano

Abstract

Rationale There is a lack of consistent national data on the evaluation of the epidemiological profile of patients with anal fistula. Objective To evaluate the epidemiological profile of patients with anal fistula at a center specialized in coloproctology. Method A cross-sectional, retrospective study was carried out between 2016 and 2018 of patients who underwent surgical procedures for the treatment of fistula in ano by the Department of Coloproctology of the Regional Hospital of Mato Grosso do Sul. Age, gender, disease duration, number of procedures, association with Crohn's disease and other comorbidities were evaluated. The data were tabulated and submitted to statistical treatment considering p < 0.05. Results 93.2% of the patients were less than 60 years old, 66.7% were male, 88.9% had the disease less than one year, the most frequent procedures were fistulotomy (55.6%) and fistulectomy (36.8%), with a greater percentage of patients having undergone only one procedure (74.4%), 8.5% had Crohn’s disease, 7.7% systemic hypertension and 3.4% had diabetes mellitus. Conclusion In the studied group, there was a predominance of anal fistulae in men under 60 years old and without comorbidities, diagnosed for up to one year, most of them submitted to fistulotomy or fistulectomy at one time. Patients operated after one year of illness and also those with Crohn’s disease were submitted mainly to curettage + seton and multiple procedures.

Surgical Outcome of Dacrystorhinostomy in Fistulous Dacryocystitis

“…11 The values of the post-surgery outcomes vs. patients gender and age showed no significant association between the variables (p-value ranging from 0.195 to 0.935) and similar was observed in one such study where p-value were insignificant ranging from 0.193 to 0.895. 12 The complication rate of the surgical procedure observed in our population was 30%, i.e., only 9 cases out of 30 showed complications from intraoperative hemorrhage (16.7%), laceration of the nasal mucosa (13.3%). However, elsewhere, a negligible complication rate of 28 %.was noted by Rahman et al 13 Further to our findings, the success rate is seconded by the relief of epiphora and lacrimal patency at the end of the last follow-up in 87% of patients, while 13% showed recurrence.…”

Surgical laser therapy for cryptoglandular anal fistula: Protocol of a systematic review and meta-analysis

“…Anal fistula, also known as fistula-in-ano, is the natural progression of perianal abscess. In fact, the disease begins with suppurative inflammation of the anal crypts, and if left untreated, the inflammation can spread to the adjacent anorectal spaces, including pelvirectal space, retrorectal space, ischiorectal space, perianal space and transsphincter space [ 1 ]. At present, the theoretical basis for the pathogenesis of cryptoglandular perianal fistula is still controversial.…”

“…The laser fiber was first introduced to fistula surgery due to its good tissue penetration, and the laser beams were used to destroy and wipe out the fistula. One of its advantages is that it can be used to diagnose and treat disease in confined spaces [ 1 , 15 ]. Another significant advantage is that low laser power can coagulate diseased tissue without vaporizing it [ 16 ].…”

Characteristics and post-operative outcomes of surgery for fistula-in-ano managed at a tertiary care hospital in Sri Lanka: a retrospective study

“…8 Several international reports on the clinicopathological characteristics, classification, treatment, and outcomes of anal fistulae have been published, including studies from India. [9][10][11] In neighboring Sri Lanka, however, the patterns of anal fistulae have not been widely studied. Therefore, recent patterns of fistula-in-ano in Sri Lanka warrant investigation.…”
