Fissurectomy combined with anoplasty and injection of botulinum toxin in treatment of anterior chronic anal fissure with hypertonia of internal anal …

2010

Abstract BACKGROUND: In patients affected by anterior chronic anal fissure (CAAF) with hypertonia of the internal anal sphincter (IAS), the role of IAS hypertonia remains unclear. The aim of this study was to evaluate the efficacy of fissurectomy combined with advancement flap and IAS injection of botulinum toxin in healing the CAAF with hypertonia of IAS resistant to medical therapy. METHODS: Ten consecutive patients were enrolled. Anorectal manometry was performed preoperatively and at 6 months. CAAF with hypertonia was defined as those associated with maximum resting pressure (MRP) values higher than 85 mmHg. All patients underwent fissurectomy and anoplasty with advancement skin flap co…

Advancement flap in the management of chronic anal fissure: A prospective study

2012

Lateral internal sphincterotomy is the surgical treatment of choice of chronic anal fissure after failure of conservative measures. Several randomized trials identified an overall risk of incontinence of 10 % mostly for flatus. Fissurectomy is the most commonly used procedure to preserve the integrity of the anal sphincters. However, a possible complication is keyhole defect that may lead to faecal soiling. In this study, chronic anal fissure (CAF) was treated by fissurectomy and anal advancement flap to preserve the anatomo-functional integrity of sphincters and to reduce healing time and the risk of anal stenosis. In patients with hypertonia, surgical treatment was combined with chemical …

Long-term follow-up (42 months) of chronic anal fissure after healing with botulinum toxin.

2002

Abstract Background & Aims: Botulinum toxin is an effective treatment in idiopathic chronic anal fissure, but the long-term outcome after healing is not well documented. We analyzed the long-term outcome of patients in whom an anal fissure had healed after botulinum toxin injection and the factors contributing to recurrence. Methods: Fifty-seven patients who had completely healed 6 months after injection of botulinum toxin were reassessed every 6 months. The follow-up was 42 months in all patients. Clinical and manometric differences between the permanently healed and the relapsed group were statistically analyzed. Results: Four patients were lost to follow-up. A fissure recurrence was show…

Improvement of wound healing after hemorrhoidectomy: a double-blind, randomized study of botulinum toxin injection.

2005

PURPOSE: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play in important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemaorrhoidectomy in reducing the maximum testing pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward ill all patients un…

Botulinum toxin A (Botox) and sweating-dose efficacy and comparison to other BoNT preparations.

2004

Abstract Background Botulinum toxin type A (BoNT/A) is 20–50 times more effective than Botulinum toxin type B (BoNT/B) concerning the treatment of muscular hypercontractions [Sloop, R.R., Cole, B.A., Escutin, R.O., 1997. Human response to botulinum toxin injection: type B compared with type A. Neurology 49, 189–194]. Botulinum toxins block motor nerves as well as autonomic fibres [Rand, M.J., Whaler, B.C., 1965. Impairment of sympathetic transmission by botulinum toxin. Nature 206, 588–591]. Objective Purpose of this study was to analyse the dose dependent reduction of sweating using the BoNT/A preparation Botox® and to compare the results with our earlier results analysing Dysport® [Braune…

Pathophysiologic quantities of endotoxin-induced tumor necrosis factor-alpha release in whole blood from patients with chronic heart failure.

2002

Bacterial endotoxin activity is elevated in patients with decompensated chronic heart failure (HF) and acts as a potent stimulus for immune activation. We sought to determine whether endotoxin, at an activity level seen in vivo (around 0.6 EU/ml), is sufficient to stimulate the secretion of tumor necrosis factor-alpha (TNF-alpha) and TNF-alpha soluble receptor (sTNFR2) in ex vivo whole blood from patients with HF. We studied 15 patients with HF (aged 65 +/- 1.9 years, New York Heart Association class 2.1 +/- 0.3, left ventricular ejection fraction 31 +/- 5%; mean +/- SEM), of whom 5 had cardiac cachexia, and 7 healthy control subjects (59 +/- 5 years, p = NS). Reference endotoxin was added …

Botulinum toxin to avoid component separation in midline large hernias.

2020

Abstract Background The goal of our study was to compare results in patients with large midline incisional hernia using modified anterior component separation versus preoperative botulinum toxin and following Rives repair, with a focus on surgical site occurrences, possibility of fascial closure, duration of hospital stay, and hernia recurrence rate. Methods From to March 2016 to June 2019, a prospective comparative study was performed in 80 consecutive patients with large midline incisional hernias and hernia transverse diameters between 11 and 17 cm under elective hernia repair at our tertiary center. Two groups were analyzed prospectively: 40 patients with preoperative botulinum toxin ad…

Botulinum toxin vs. topical glyceryl trinitrate ointment for pain control in patients undergoing hemorrhoidectomy: a randomized trial.

2007

PURPOSE: The maximum resting pressure in the anal canal is greatly raised after hemorrhoidectomy. This increase is likely to be the cause of postoperative pain, which is still the most troublesome early problem after hemorrhoidectomy. This study was designed to compare, after hemorrhoidectomy, the effects of intrasphincter injection of botulinum toxin vs. application of glyceryl trinitrate ointment in improving wound heating and reducing postoperative pain at rest or during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 40 days after hemorrhoi…
