RESUMO
BACKGROUND/AIMS: Proximal biliary plastic stent migration (PSM) remains a challenging complication. The study aims at determining the PSM rate, retrieval outcomes and factors associated with PSM. METHODS: Endoscopy database was analyzed from January 2016 to January 2021 to identify 1137 patients, who underwent stent removal or repeat endoscopic retrograde cholangiopancreatography (ERCP). Demography, methods of stent retrieval, outcomes and complications were noted. Logistic regression was performed to determine risk factors for PSM. Propensity score matching was done in a 1:1 manner using age, sex, comorbidities and indication to assess endoscopy-related factors. Clinical trial registration done (CTRI/2022/02/040516). RESULTS: PSM was noted in 74 (6.5%) cases. Stent retrieval was successful in 94.59% (70/74) of cases. A balloon catheter (46/74) was commonly used. Technical failure was due to an impacted stent (2) and stent above the stricture (2). Complications were seen in 2.7% of cases. On multi-variate regression, sphincteroplasty at index ERCP (Odds ratio [OR] = 5.68, 95% confidence interval [CI] = 2.7-11.89), stent length < 10 cm (OR = 8.53, 95% CI = 3.2-22.47), 7-Fr stent (OR = 18.25, 95% CI = 6.5-50.64), dilated bile duct (mean diameter- 9.2 ± 3.94 mm) (OR = 0.384, 95% CI = 0.18-0.72) and delayed ERCP by > 3 months from index ERCP (OR = 15.28, 95% CI = 8.1-28.49). After performing propensity score matching for age, sex, comorbidities and indication to determine endoscopy-related factors, 7-Fr stent size (OR 3.495; 95% CI-1.23-9.93) and duration of indwelling stent for more than three months (OR-3.37; 95% CI-1.646-6.76) were significantly associated with proximal stent migration. CONCLUSION: Proximally migrated straight stents can be successfully retrieved using standard accessories. The use of 7-Fr size stent, stents indwelling for more than three months, sphincteroplasty at index ERCP, stent length < 10 cm and dilated bile duct were associated with increased risk of proximal migration of straight biliary plastic stents. After propensity score matching, the use of 7-Fr size stents and stent indwelling for over three months were endoscopy-related factors associated with proximal migration.
RESUMO
BACKGROUND AND AIMS: Budd Chiari syndrome (BCS) commonly affects adolescents and adults. With improved survival, important quality-of-life parameters such as sexual life and fertility become more relevant. This study was aimed to assess the gonadal function in male patients with BCS and the effect of treatment on gonadal function. METHODS: Thirty male patients with newly diagnosed BCS were prospectively assessed for the presence of gonadal dysfunction. Erectile function was assessed using standardized International Index of Erectile Function questionnaire (IIEF). Follicular stimulating hormone (FSH), luteinizing hormone (LH), sex hormone-binding globulin (SHBG), estradiol, total testosterone (TT), calculated free testosterone (cFT), calculated bioavailable testosterone (cBT), sperm count, and sperm motility were compared at baseline and at 6 months of treatment for the assessment of gonadal function. RESULTS: Sixteen (53.3%) out of 30 patients were sexually active at the time of study and 5/16 (31%) had erectile dysfunction. Hypogonadotropic hypogonadism (HH) was the most common pattern seen in 50% cases followed by hypergonadotropic hypogonadism (HyH) in 23% cases. 27% patients had eugonadism. At 6 months of treatment, 60% of patients in HH group became eugonadal as compared to only 14% in HyH group. Proportion of patients with erectile dysfunction reduced (5/16 vs 1/16) after 6 months of therapy. The improvement in sperm count and sperm motility was not significant. CONCLUSION: Gonadal dysfunction is common in male patients with BCS. HH remains the most common type of hypogonadism BCS and the type which improves significantly after treatment.
