RESUMO

OBJECTIVE: To evaluate the relationship between heart failure (HF), chronic obstructive pulmonary disease (COPD), and smoking with the development of urethral stricture (US) by examining the patients who underwent transurethral prostate resection procedure, with and without the development of US in their follow-ups. METHODS: Among the patients who underwent transurethral resection of the prostate, 50 patients who developed US during their follow-ups formed group 1, while a total of 50 patients who did not develop US and were selected by lot formed group 2. The relationship between the patients' data on HF, COPD and smoking status and the development of US was investigated. RESULTS: The mean number of cigarettes smoked was statistically significantly high in the group with stricture (p = 0.007). Furthermore, pulmonary function test parameters of patients such as forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and FEV1/FVC were found to be statistically significantly higher in Group 2 (p < 0.001, p < 0.001, and p = 0.008, respectively). In the logistic regression analysis, being a smoker was found to be the strongest predictor (p = 0.032). CONCLUSION: Our study concluded that smoking, HF, and COPD significantly increase the risk of developing stricture after transurethral resection of the prostate.

OBJETIVO: Evaluar la relación de la insuficiencia cardiaca, la enfermedad pulmonar obstructiva crónica y el tabaquismo con el desarrollo de estenosis de uretra en pacientes sometidos a resección transuretral de próstata con y sin desarrollo de estenosis de uretra en su seguimiento. MÉTODO: Cincuenta pacientes que desarrollaron estenosis de uretra durante su seguimiento formaron el grupo 1, y 50 pacientes que no desarrollaron estenosis de uretra y fueron seleccionados por lote formaron el grupo 2. Se investigó la relación de los datos de los pacientes sobre insuficiencia cardiaca, enfermedad pulmonar obstructiva crónica y tabaquismo con el desarrollo de estenosis uretral. RESULTADOS: La media de cigarrillos fumados fue significativamente más alta en el grupo con estenosis (p = 0.007). Además, se encontró que los parámetros de las pruebas de función pulmonar de los pacientes, como FEV1, FVC y FEV1/FVC, eran significativamente más altos en el grupo 2 (p < 0.001, p < 0.001 y p = 0.008, respectivamente). CONCLUSIONES: El tabaquismo, la insuficiencia cardiaca y la enfermedad pulmonar obstructiva crónica aumentan significativamente el riesgo de desarrollar estenosis después de una resección transuretral de próstata.

RESUMO

Primary gastrointestinal non-Hodgkin lymphoma, while rare, most often presents as diffuse large B-cell lymphoma located in the stomach or ileocecal region. Presenting symptoms include abdominal pain, gastrointestinal bleeding, weight loss, or obstructive symptoms. Imaging can reveal ileitis or obstruction. We report a case of a man from Honduras with latent tuberculosis and chronic hepatitis B who presented with features of Crohn's disease through clinical, radiologic, and endoscopic findings but was ultimately diagnosed with diffuse large B-cell lymphoma by histology. We emphasize the importance of maintaining a broad differential for ileitis and the importance of histologic sampling when evaluating ileitis.

RESUMO

ABSTRACT Introduction: Urethral stricture is a common, albeit complex, condition that predominantly affects men. The aim of this study was to translate, culturally adapt, and validate the Patient-Reported Outcome Measure questionnaire for patients undergoing urethroplasty (USS-PROM) into Brazilian Portuguese using validated psychometric criteria. Materials and Methods: The process involved translating and culturally adapting the original USS-PROM into Brazilian Portuguese (USS-PROMbr), synthesizing, back-translating, cross-culturally adapting, and analyzing the pre-final version with experts from our committee. This pre-version was administered to 10 patients who had undergone urethroplasty by the Reconstructive Urology team at the Hospital de Clínicas de Porto Alegre for face validation, linguistic, and semantic adjustments, resulting in the final USS-PROMbr version. Subsequently, well-established psychometric criteria, including content validity, internal consistency, and test-retest reproducibility, were assessed after administering the questionnaire to a total of 56 patients, with 50 of them responding to the test and retest. Results: Evaluation of the pre-final version identified 15 questions as clear, and only one question was considered somewhat unclear necessitating modifications based on patient suggestions and subsequent reassessment by the research team. Psychometric criteria demonstrated good content validity, with a content validity index exceeding 0.80 for all questions; good internal consistency, Cronbach's alpha of 0.77, ranging from 0.70 to 0.78 with the exclusion of any item, and item-total correlations ranging from 0.33 to 0.67. The test-retest intraclass correlation coefficient was 0.74 for the lower urinary tract symptoms construct (Q1-Q6). Conclusion: The USS-PROMbr demonstrated acceptable cross-cultural adaptation and psychometric properties, making it a valid and useful tool for evaluating patients undergoing urethroplasty.

RESUMO

Objective: To present a series of cases with our initial experience and short-term outcomes of a modified vaginal mucosal flap urethroplasty. Methods: Patients diagnosed with urethral stricture and operated by the same operative technique between January 2012 and January 2018 were followed for at least 6 months. Uroflowmetry and clinical outcomes were evaluated. Results: Nineteen patients were included with an average age of 56.4 years, mean preoperative Qmax of 5.3 ml/s, and PVR of 101.4 mL. After 6 months of the procedure, the mean Qmax improved to 14.7 mL/s (p<0.05), PVR decreased to 47.3 mL (p<0.05), and 84.2% of all patients reported improvement in clinical self-reported symptoms. There was an improvement in symptoms such as voiding effort in 84.2% of patients, weak stream (89.5%), and recurrent urinary tract infection (85.7%). The success rate (absence of symptoms and normal Qmax with no significant PVR) of the procedure was 84.2%. Conclusion: The described technique was considered effective for the treatment of female urethra stricture, with a high clinical success rate and an objective improvement of Qmax and decrease in PVR after 6 months of the procedure.

RESUMO

Point-of-care ultrasound (POCUS) refers to the use of ultrasound imaging through pocket-sized sonographic devices at the patient's bedside, to make a diagnosis or direct a procedure and immediately answer a clinical question. Its goal is to broaden the physical examination, not to replace conventional ultrasound studies. POCUS has evolved as a complement to physical examination and has been adopted by different medical specialties, including hepatology. A narrative synthesis of the evidence on the applications of POCUS in hepatology was carried out, describing its usefulness in the diagnosis of cirrhosis of the liver, metabolic dysfunction-associated steatotic liver disease (MASLD), decompensated cirrhosis, and portal hypertension. The review also encompasses more recent applications in the hemodynamic evaluation of the critically ill patient with cirrhosis of the liver, patients with other liver diseases, as well as in the ultrasound guidance of procedures. POCUS could make up part of the daily clinical practice of gastroenterologists and hepatologists, simplifying the initial evaluation of patients and optimizing clinical management. Its accessibility, ease of use, and low adverse event profile make POCUS a useful tool for the properly trained physician in the adequate clinical setting. The aim of this review was to describe the available evidence on the usefulness of POCUS in the daily clinical practice of gastroenterologists and hepatologists.

RESUMO

ABSTRACT Introduction: There is lack of papers dedicated to the laparoscopic buccal mucosa graft (BMG) ureteroplasty of the complex upper ureteral stricture. The aim of this study is to evaluate the results of laparoscopic BMG ureteroplasty in patients with complex proximal ureteral stricture. Material and methods: Twenty-four patients underwent laparoscopic ventral onlay BMG ureteroplasty for long or recurrent proximal ureteral stricture not amenable to uretero-ureteral anastomosis over 2019-2022. Patient demographics, operative time, estimated blood loss, length of stay, follow-up, intra- and postoperative complication rate and percentage of stricture-free at last visit were analyzed. Results: The mean stricture length was 3.6 cm. The mean operative time was 208.3 min, while mean blood loss was 75.8 mL. The length of hospital stay was 7.3 days. No intraoperative complications were observed. Postoperatively, seven patients developed complications (29.2%). Five patients experienced a Grade II (according to Clavien nomenclature). Two patients developed a Grade IIIa complication, which included leakage of the anastomosis site. The mean follow-up was on the 22 months with stricture free rate 87.5%. Conclusion: Patients with proximal ureteral strictures could be effectively treated by laparoscopic ventral onlay ureteroplasty with a buccal mucosa graft.

RESUMO

BACKGROUND: The length of conventional single-use cholangioscopes poses a challenge for percutaneous or laparoscopic approaches for direct visualization of the biliary tract. The aim of this retrospective observational clinical study was to assess the use of a dedicated percutaneous short single-operator cholangioscope (PSSOC) for diagnosis and treatment of benign or malignant biliary diseases. METHODS: Retrospective analysis of a prospectively maintained database including all consecutive patients undergoing percutaneous transhepatic cholangioscopy with the PSSOC between 06/2021 and 01/2023. RESULTS: Forty patients were included (22F/18 M, age 58.7 ± 16.7 years). The diagnostic and therapeutic management plan was based on procedural findings. Indications were bile duct obstruction associated with complex anatomy (n = 13), choledocholithiasis (n = 11), suspected malignant stenosis of the biliary tract (n = 11), biliary stent placement (n = 2) and removal (n = 1), and failed endoscopic retrograde cholangiopancreatography (n = 2). The cholangioscopies were diagnostic (n = 5), therapeutic (n = 20) or both simultaneously (n = 15). The most frequent procedures were electrohydraulic lithotripsy (n = 25) and biopsy sampling (n = 12). Complications occurred in 7 cases (17.5%), including cholangitis (n = 4, B2), pleural perforation (n = 1, B2), portal bleeding (n = 1, B3), and Tako-Tsubo syndrome (n = 1, B3), classified according to the Society of Interventional Radiology classification. Intraprocedural visual diagnosis was confirmed by the histopathologic result in 11/12 patients in which biopsies were performed (91.7%). PSSOC was relevant to avoid surgery in 2 patients (5%) with indeterminate strictures, allowing to rule out malignancy and treat the lithiasis. CONCLUSIONS: Direct visualization of the biliary tract enabled targeted biopsies for histopathological diagnosis. The visual and histopathological diagnoses were concordant in all but one case. Percutaneous cholangioscopy with a dedicated PSSOC allows to optimize identification and treatment of complex biliary disease including biliary lithiasis while assessing bile duct patency. The clinical use of the novel PSSOC system was safe and effective and could prevent surgical exploration in select patients.

RESUMO

Colorectal signet ring cell carcinoma is a rare type of colon cancer. Early diagnosis remains challenging because of nonspecific colonoscopy findings, such as diffuse circumferential thickening, stricture, and ulcerations, and the potential absence of typical pathological features in the initial biopsy sample. In this article, we report a 41-year-old man with ulcerating rectosigmoid stricture in the rectosigmoid colon with inconclusive histology. Subsequently, the patient developed small bowel obstruction and was diagnosed with stage 4 colorectal signet ring cell carcinoma with peritoneal carcinomatosis.
