Selection Of Optimal Approach To Diagnosis Of Anal Canal Stenosis
Keywords:
Post-operative stenosis of the anal canal, clinical presentation, diagnosisAbstract
This study included 102 patients with PSAC. The distribution of all patients with postoperative anus narrowing by degree showed that the total number of patients with grade II PSAC reached 84 (82.3%) cases. Grade III postoperative anus narrowing was recorded in 18 (17.6%) patients. Patients with the cutaneous form of anus stricture occupied a dominant position, accounting for 62 (60.8%) cases. One of the main reasons for the development of the muscular form of PSAC was anal sphincter pectinosis combined with rectal fistulas, which accounted for 13 (12.7%) cases. The distribution of all patients with postoperative anus narrowing according to the frequency of concomitant chronic surgical pathologies of the anal canal showed that the majority—57 (55.9%) cases—were patients with chronic anal fissures. The use of ultrasound and MRI with 92.4% and 100% informativeness, respectively, allows for the identification of the degree and nature of inflammatory pathological changes in the anal canal mucosa, pararectal tissue, and anal sphincter, which optimizes preparation for surgical correction.
