Safety and efficacy of the treatment of chronic anal fissure by lateral internal sphincterotomy: A retrospective cohort study.

ABSTRACT: Background:An anal fissure is one of the most common anorectal diseases resulting from a longitudinal tear in anoderm under the dentate line. It causes severe pain during defecation, and the resulting emotional stress leads to a reduction in the overall quality of life of a person. There are several medical and surgical treatment procedures that are employed to treat anal fissures. In the present retrospective study, we aimed to evaluate the safety and efficacy of lateral internal sphincterotomy (LIS) surgical procedure for the treatment of chronic anal fissure. Additionally, we also analyzed the complications arising after the surgery and the factors affecting the complications. Methods:The present study is a retrospective study that included 691 patients treated for chronic anal fissure in a private sector setting, by a single Saudi female surgeon, starting from April 2004 to April 2020. Results:Out of the 691 patients included in the study, all the patients were female, with an average age of 45.77 years (ranging from 17 to 82 years). Major complaints of the patients were as follows: pain, bleeding, constipation, pruritus, perianal discharge. Recurrence was reported in 2 patients (0.3%) while, 3 patients (0.4%) developed gas incontinence.The complaints of all patients with gas incontinence regressed over a period of time. Conclusion:This study reports that lateral internal sphincterotomy (LIS) is a safe surgical treatment for chronic anal fissure, leading to a reduction in recurrence, incontinence rate and substantially improves symptoms, especially pain.

Project description:Chronic anal fissure (CAF) is a painful tear or crack which occurs in the anoderm. The optimal algorithm of therapy for CAF is still debated. Lateral internal sphincterotomy (LIS) is a surgical treatment, considered as the 'gold standard' therapy for CAF. It relieves CAF symptoms with a high rate of healing. Chemical sphincterotomy (CS) with nitrates, calcium blockers or botulinum toxin (BTX) is safe, with the rapid relief of pain, mild side-effects and no risk of surgery or anesthesia, but is a statistically less effective therapy for CAF than LIS. This article considers if aggressive treatment should only be offered to patients who fail pharmacological sphincterotomy. Aspects of anal fissure etiology, epidemiology and pathophysiology are considered with their meaning for further management of CAF. A molecular model of chemical interdependence significant for the chemistry of CAF healing is examined. Its application may influence the development of optimal therapy for CAF. BTX is currently considered the most effective type of CS and discussion in this article scrutinizes this method specifically. Although the effectiveness of BTX vs. LIS has been discussed, the essential focus of the article concerns identifying the best therapy application for anal fissure. Elements are presented which may help us to predict CAF healing. They provide rationale for the expansion of the CAF therapy algorithm. Ethical and economic factors are also considered in brief. As long as the patient is willing to accept the potential risk of fecal incontinence, we have grounds for the 'gold standard' (LIS) as the first-line treatment for CAF. The author concludes that, when the diagnosis of the anal fissure is established, CS should be considered for both ethical and economic reasons. He is convinced that a greater understanding and recognition of benign anal disorders by the GP and a proactive involvement at the point of initial diagnosis would facilitate the consideration of CS at an earlier, more practical stage with improved outcomes for the patient.

Project description:IntroductionChronic internal carotid artery occlusion (CICAO) is a common cause of stroke and ischemia recurrence. An increasing number of reports have highlighted the potential of hybrid surgery for treating CICAO. There are few studies, specifically nonrandomized controlled trials, on the safety and effectiveness of hybrid surgery for the treatment of CICAO, so in this study, we hypothesized that hybrid surgery would be safe, have an acceptable complication rate and a high success rate.MethodsMEDLINE, Embase, Cochrane Library, and Web of Science databases were searched for relevant studies published up to January 30, 2023. The primary endpoint was recanalization rates of occluded vessels, and the secondary endpoint was perioperative death and procedure-related complications. Subgroup analysis focused on the recanalization rates of endovascular intervention (EI) and hybrid surgery, as well as the rates of recanalization below the clinoid segment and at the clinoid segment and beyond. The follow-up visit was conducted at least 3 months after surgery, and stenosis or occlusion recurrence was confirmed by review of CTA or DSA scan.ResultsThe databases were searched and 1,709 records were identified, of which 16 articles were used in the meta-analysis, and 464 CICAO patients with complete data who underwent hybrid surgery were enrolled. Hybrid surgery was associated with higher success rates (RD = 0.87, 95% CI [0.84-0.91], p < 0.00001) than EI (OR = 4.71, 95% CI [2.32-9.56], p < 0.0001). The procedural success rate in the below-clinoid segment group was significantly higher than that in the clinoid segment and beyond group (OR = 13.76, 95% CI [5.31-35.66], p < 0.00001). The total periprocedural complication rate was low (RD = 0.11, 95% CI [0.07-0.15], p < 0.00001 and RD = 0.04, 95% CI [0.00-0.07], p = 0.03). Target vessel restenosis or reocclusion occurred in 35 patients (8%) during the follow-up period (RD = 0.08, 95% CI [0.04-0.12], p < 0.0001).ConclusionHybrid surgery is the combination of the advantages of open surgery and EI, has a high success rate and a low risk of recurrence of stenosis and occlusion in the long term. Randomized controlled trials on hybrid surgery for internal carotid artery occlusion are necessary.

Project description:BackgroundTraditional ureteral stricture balloon dilation was performed with fluoroscopic assistance. The use of a C-arm X-ray machine delivered hazardous radiation to both surgeons and patients. In attempt to eliminate the radiation hazard, we developed a F4.5/6.5 ureteroscope assisted intraoperative X-ray free balloon dilation surgical approach to treat ureteral stricture and to verify its safety and efficacy. Specifically, this method had not been previously reported in the literature.MethodsWe demonstrated an intraoperative X-ray free balloon dilation with detailed step-by-step procedures description and video illustration. Clinical data of patients undergoing minimally invasive endourological treatment for ureteral stricture between February 2015 and November 2019 were retrospectively analyzed. All steps of X-ray free balloon dilation were carried out under direct vision of a ureteroscope, and two indwelling F7 ureteral stents were used for 3 months postoperatively. Preoperative, intraoperative, and postoperative clinical data were evaluated, and follow-up results were reported. Successful outcome was defined as disappearance of preoperative symptoms, relief of hydronephrosis and stable of renal function. Univariate and multivariate prognostic analyses were performed.ResultsWe identified 109 patients who received endourological treatment for ureteral stricture in our hospital's medical database. After excluding patients undergone simple catheter dilation, endoureterotomy and other treatment method, 76 patients received balloon dilation without intraoperative fluoroscopic guidance were included in our study. 4/76 patients report a grade II complication (urinary tract infections, UTIs) according to Clavien Dindo classification. In the 22.5 months median follow-up time, the one-year cumulative success rate and two-year cumulative success rate were 85.9% and 80.2% (61/76), respectively, and the majority (13/15, 86.7%) recurrence of ureteral stricture or hydronephrosis deterioration were found within two years after surgery. The longer stenotic lesion length (>5 mm) or multiple ureter stenosis and compromised blood supply of ureter were significantly associated with postoperative stenosis recurrence.ConclusionsX-ray free endoscopic balloon dilation is a safe and effective procedure that could be performed on patients with ureteral stenosis.

Project description:Although there are several reports of the significant efficacy of zolpidem for treating dystonia, zolpidem is still considered an anecdotal treatment. Here, we evaluated the efficacy and safety of zolpidem for treating residual dystonia in patients who previously received various neurosurgical treatments majorly including deep brain stimulation and radiofrequency ablation. We retrospectively reviewed medical records from January 2021 to September 2021 to identify patients with dystonia who had been prescribed zolpidem after undergoing neurosurgery. Twenty patients were enrolled in this study, including those with blepharospasm (two), tongue dystonia (four), mouth dystonia (one), spasmodic dysphonia (two), cervical dystonia (six), focal hand dystonia (three), hemidystonia (two), blepharospasm with cervical dystonia (one), and mouth dystonia with cervical dystonia (one). Single doses of zolpidem ranged between 2.5 and 10 mg, while daily dosages ranged from 10 to 30 mg. The zolpidem dose prescribed was 5-10 mg, with single and daily doses of 7 ± 2.9 and 14.5 ± 6.0 mg, respectively. With zolpidem administration, the participants' Burke-Fahn-Marsden Dystonia Rating Scale-Movement Scale score significantly improved from 8.1 ± 6.7 to 3.7 ± 2.5 (50.6% improvement, p < 0.0001). Improvements in arm dystonia, blepharospasm, and spasmodic dysphonia were observed using the Arm Dystonia Disability Scale, Jankovic Rating Scale, and Voice Handicap Index, respectively. No improvements were observed in cervical dystonia on the Toronto Western Spasmodic Torticollis Rating Scale. Drowsiness, including three cases each of mild and moderate drowsiness, was the most frequent adverse effect (30%), which persisted for 2-3 h. Transient amnesia and rapid eye movement sleep behavior disorder occurred in two patients and one patient, respectively. Although our findings suggest that zolpidem can be a valuable treatment option for patients with residual dystonia after neurosurgical treatments, the beneficial effects for cervical dystonia were limited.

Project description:BackgroundThe impact of aortoiliac occlusive disease on kidney transplantation remains unclear. This study aims to investigate the clinical outcomes of kidney transplant patients with aortoiliac atherosclerotic stenosis.MethodsRetrospective data from our transplant center were used to identify patients undergoing kidney transplantation between January 2010 and December 2020. Aortoiliac atherosclerotic stenosis was screened and stratified by the Trans-Atlantic Inter-Society Consensus (TASC) II classification. The primary outcome was patient survival. Secondary outcomes were 90-day mortality, death-censored graft survival, graft function, and arterial complications. Propensity score matching was used to match all patients in the stenosis group with patients without stenosis sharing similar characteristics.ResultsThe analysis included 655 patients, 524 without stenosis and 131 with aortoiliac stenosis (95 with TASC A/B stenosis and 36 with TASC C/D stenosis). Recipient age [median (IQR), 66 (60-70) vs. 66 (59-71) years; P =0.47], sex [male: 87 (66%) vs. 355 (68%), P =0.85], and comorbidities were comparable between the stenosis and no-stenosis groups. Forty-six (35%) patients with stenosis were symptomatic. Patient survival was significantly lower in the stenosis group compared with the no-stenosis group (TASC A/B: 30.6% vs. no-stenosis: 44.1%, P =0.013; TASC C/D: 11.4% vs. no-stenosis: 44.1%, P <0.001). The incidence rates of artery dissection, lower extremity ischemia, and acute thrombosis were significantly higher in the stenosis group ( P <0.001). However, death-censored graft survival (TASC A/B: 73.6% vs. no-stenosis: 72.9%, P =0.62; TASC C/D: 58.1% vs. no-stenosis: 72.9%, P =0.16) and graft function were comparable between the groups.ConclusionsAortoiliac atherosclerotic stenosis significantly impacts patient survival but not graft survival. Our analyses suggest that patients with TASC A/B stenosis have prolonged survival and enhanced quality of life through kidney transplantation. However, for patients with TASC C/D stenosis, kidney transplantation improves quality of life without bringing survival benefits.
