Introduction Perianal fistulas are a common problem. Video-assisted anal fistula treatment is a new technique for the management of this difficult condition. We describe our initial experience with the technique to facilitate the treatment of established perianal fistulas. Methods We reviewed a prospectively maintained database relating to consecutive patients undergoing video-assisted anal fistula treatment in a single unit. Results Seventy-eight consecutive patients had their perianal fistulas treated with video-assistance from November 2014 to June 2016. Complete follow-up data were available in 74 patients, with median follow-up of 14 months (interquartile range 7-19 months). There were no complications and all patients were treated as day cases. Most patients had recurrent disease, with 57 (77%) having had previous fistula surgery. At follow-up, 60 (81%) patients reported themselves 'cured' (asymptomatic) including 5 patients with Crohn's disease and one who had undergone 10 previous surgical procedures. Logistical stepwise regression did not demonstrate any statistically significant factors that may have been considered to affect outcome (age, gender, diabetes, previous I&D, Crohn's disease, smoking, type of fistula). Conclusions Our data have shown that video-assisted anal fistula treatment is safe and effective in the management of perianal fistulas in our patients and this suggests it may be applied to all patients regardless of comorbidity, underlying pathology or type of fistula.
Conventional radical surgery for pelvic malignancies often will result in debilitating functional problems. As advances in surgical techniques and management options become more available, patients can have better functional outcomes, specifically in the lower urinary tract. Nerve-sparing techniques as well as vascular preservation are becoming more important to preserve function as patient survival is improving. Additionally, newer methods are being explored, such as nerve stimulation for those who are unable to empty adequately. This article also addresses different management options for specific voiding dysfunction that may result from pelvic surgery. Preventative strategies such as nerve preservation during surgery are an important concept to prevent urinary dysfunction. The goal to good functional outcomes includes maintaining reservoir compliance and capacity as well as allowing proper outlet for voiding. We discuss different modalities to help achieve a functional lower urinary tract for patients with lower urinary tract dysfunction after pelvic surgery.
Methylene blue is an intravenously administered agent that may potentiate serotonin syndrome. The usage of methylene blue to evaluate ureters for injuries and patency during urological surgeries is recognized as common practice. However, there is no mention of serotonin syndrome caused by methylene blue in urological literature or for urological surgery. We report the first urological case in order to raise awareness of the risk for serotonin toxicity with utilizing methylene blue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
