The core-out technique causes a significant decrease in squeeze pressures, which reflects damage to the external anal sphincter. This could lead to incontinence in high-risk patients. Curettage is a simple technique that preserves the values of squeeze pressures without increasing recurrence rates.

Extensive local surgery of giant perianal condyloma with anoplastic reconstruction gives good results even in HIV-positive patients.

The aim of this study was to assess the evolution of sexual function over time after rectal cancer surgery and to identify risk factors that may have an impact on the deterioration of postoperative function. Method:This was a prospective cohort study of sexual function after rectal cancer surgery using the International Index of Erectile Function (IIEF) and Female Sexual Function Index (FSFI) preoperatively and at 6 and 12 months after surgery. Predictive factors of worsening were identified by univariate and multivariate analysis.Results: One hundred and one patients were included (56 men and 45 women). In men, the average IIEF showed decreased erectile function and intercourse satisfaction at 6 months (respectively 21.58 ± 7.18 to 16.60 ± 7.96, p = 0.002 and 10.87 ± 2.94, to 8.09 ± 4.45, p = 0.002) with recovery at 1 year. As a percentage, erectile dysfunction increased from the preoperative value to 6 months (64.5% vs 87.1%, p = 0.022) and was observed in 72% at 1 year. Patients with moderate to severe dysfunction increased from 22% preoperatively to 58% (p = 0.009) at 6 months and 44% at 1 year (p < 0.0001). Neoadjuvant chemoradiotherapy (OR 5.4, 95% CI 0.9-29.6; p = 0.041) and erectile worsening at 6 months (OR 20, 95% CI 1.6-238; p = 0.004) were independent factors for worse function at 6 or 12 months, respectively. No significant worsening of the FSFI was found, although there was an improvement in lubrication and orgasm. Conclusion:Temporary deterioration of erectile function in men is common at 6 months after surgery and chemoradiotherapy is the only predictive factor. Furthermore, patients who remain dysfunctional show an increase in the severity of symptoms in relation to the preoperative period.

Aim Transanal flap is an attractive technique for complex fistulas. The aim of this study was to identify factors associated with poor outcome, recurrence and incontinence. Method All patients who underwent an advancement flap for the treatment of a complex anal fistula between 1995 and 2019 were prospectively enrolled. The patient data obtained included age, sex, body mass index, comorbid conditions and smoking history. The fistula characteristics analysed included previous anal surgery, anatomy of the fistula according to Park's classification, horseshoe or supralevator extension and preoperative seton drainage. The postoperative data registered included complications, postoperative stay, recurrence and incontinence. Predictive factors for recurrence and incontinence were identified using univariate and multivariate analysis. Results One hundred and ninety patients were included; 134 (70.5%) were men and the mean patient age was 50 years. The median length of follow-up was 44.6 months. The fistula recurred in 14 patients (7.3%). Before surgery, 20 patients (10.5%) reported incontinence symptoms. In the continent patients a Wexner postoperative score of 0 was identified in 79.4%. Wexner scores between 1 and 3 were observed in 17% and scores of 4 or more in five patients (3%). Factors associated with recurrence included age < 50 years (OR = 4.8, P = 0.02, 95% CI 1.2-19), smoking (OR = 4.1, P = 0.03, 95% CI 1-16.5) and suprasphincteric fistula (OR = 0.5, P = 0.01, 95% CI 0.2-0.8) in multivariate log regression analysis. Major incontinence was influenced by female sex and previous anal surgery (OR = 7.5, P = 0.003, 95% CI 1.6-34 and OR = 0.1, P = 0.007, 95% CI 0.1-0.7, respectively). Conclusion Full-thickness transanal advancement flap is a good treatment for complex anal fistula repair. This study provides relevant information on risk factors for failure of therapy and incontinence, which can help in advising patients before surgery and planning a good treatment strategy.
