ABS-SMART (Aortic Balloon Supporting for Superior Mesenteric Artery Recanalization Technique): A New Technical Option for Recanalization of Complete Superior Mesenteric Artery Occlusion in Chronic Mesenteric Ischemia.

OBJECTIVE: To report our experience with a new technique for recanalization of the superior mesenteric artery (SMA)/celiac trunk (CT) with complete occlusion at the origin. TECHNIQUE: We describe our ABS-SMART (Aortic Balloon Supporting for Superior Mesenteric Artery Recanalization Technique) for recanalization of the CT and SMA in cases of complete occlusion of these arteries with a short or inexistent stump, which usually corresponds to chronic lesions with important calcification of the ostium. CONCLUSION: The ABS-SMART is an alternative for the recanalization of visceral arteries in cases where other conventional techniques have failed. It is particularly useful in scenarios characterized by a short occlusion at the origin of the target vessel, with no entry stump or severe calcification at the origin. CLINICAL IMPACT: Catheterization and recanalization of visceral stenoses may pose a challenge in some cases, as for example in the presence of a very narrow angle between the root or origin of the vessel and the aorta, as well as in the case of long and calcified stenoses, or when arteriography is unable to visualize the origin of the vessel. The present study describes our experience with the endovascular revascularization of visceral vessels using an aortic balloon-supported recanalization technique not previously described in the literature, that may be an effective alternative for the treatment of lesions of difficult access, such as total occlusion at the origin of the target vessel, with no entry stump or severe calcification at the origin of the SMA and CT, by improving the chances for technical success.

A Case in Which a Urethral Catheter Could Be Indwelled by an Anterograde Approach After It Was Difficult to Indwell at the Start of Robot-Assisted Laparoscopic Radical Prostatectomy.

A case in which a urethral catheter could not be indwelled at the start of robot-assisted laparoscopic radical prostatectomy (RARP) is reported. A 64-year-old man was admitted to the hospital for RARP with a diagnosis of prostate cancer cT2aN0M0. At the start of RARP, a pseudo-urethra was formed by inserting a urethral catheter, so surgery was started with a transabdominal posterior approach without indwelling the urethral catheter. The urethra was opened during bladder neck resection, a guide wire was inserted anterogradely, the urethra was dilated retrogradely, and a urethral catheter was indwelled. After that, the procedure was performed as usual, and the operation was completed. When the urethral catheter could not be indwelled at the start of RARP, it was possible to do so using an anterograde approach during the operation.

PURPOSE: The purpose of this study was to investigate the clinical impact on the global function of the shoulder of the use of the anterolateral approach for nailing. MATERIAL AND METHODS: A retrospective cohort at the public sector of Centenario Hospital Miguel Hidalgo in Aguascalientes, Mexico between 2011 and 2016 was analysed. Inclusion criteria were: patients with anterolateral humeral nailing approach. Clinical assessment using the Constant-Murley score, shoulder range of motion and quick DASH questionnaire. RESULTS: Seventeen patients, 16 treated for humeral shaft fracture and one for humeral fibrous dyslasia were obtained. Mean score on Constant-Murley scale was 84.05 with 76.4% of patients achieving excellent result ( 75 points). One patient had a poor functional outcome. The mean quickDASH score was 17.5 points. CONCLUSIONS: The anterolateral approach for humeral nailing has good functional outcome in our series.

OBJETIVO: El propósito de este estudio es investigar el impacto clínico en la función global en el hombro intervenido para el abordaje anterolateral de enclavado centromedular de húmero. MATERIAL Y MÉTODOS: Se trata de una cohorte retrospectiva de casos tratados entre 2011 y 2016. Como criterio de inclusión se revisó todo paciente con antecedente de enclavado de húmero con abordaje anterolateral. Se realizó una evaluación con la escala funcional de Constant-Murley, arquimetría comparativa de ambos hombros y la aplicación de cuestionario quick DASH. RESULTADOS: Se obtuvieron 17 pacientes, 16 tratados para fracturas diafisarias de húmero y uno para displasia fibrosa de húmero. El puntaje promedio de la escala de Constant-Murley obtenido fue de 84.05, 76.4% de los pacientes obtuvieron excelentes resultados ( 75 puntos). Un paciente tuvo un resultado funcional deficiente. El puntaje promedio de quick DASH obtenido fue de 17.5 puntos. CONCLUSIONES: El abordaje anterolateral para enclavado centromedular de húmero tiene buen pronóstico funcional en nuestra serie de casos.

Endoscopic ultrasound-guided biliary intervention in patients with surgically altered anatomy.

AIM: To evaluate the efficacy of endoscopic ultrasound guided biliary drainage (EUS-BD) in patients with surgically altered anatomies. METHODS: We performed a search of the MEDLINE database for studies published between 2001 to July 2014 reporting on EUS-BD in patients with surgically altered anatomy using the terms "EUS drainage" and "altered anatomy". All relevant articles were accessed in full text. A manual search of the reference lists of relevant retrieved articles was also performed. Only full-text English papers were included. Data regarding age, gender, diagnosis, method of EUS-BD and intervention, type of altered anatomy, technical success, clinical success, and complications were extracted and collected. Anatomic alterations were categorized as: group 1, Billroth I; group 2, Billroth II; group 4, Roux-en-Y with gastric bypass; and group 3, all other types. RESULTS: Twenty three articles identified in the literature search, three reports were from the same group with different numbers of cases. In total, 101 cases of EUS-BD in patients with altered anatomy were identified. Twenty-seven cases had no information and were excluded. Seventy four cases were included for analysis. Data of EUS-BD in patients categorized as group 1, 2 and 4 were limited with 2, 3 and 6 cases with EUS-BD done respectively. Thirty four cases with EUS-BD were reported in group 3. The pooled technical success, clinical success, and complication rates of all reports with available data were 89.18%, 91.07% and 17.5%, respectively. The results are similar to the reported outcomes of EUS-BD in general, however, with limited data of EUS-BD in patients with altered anatomy rendered it difficult to draw a firm conclusion. CONCLUSION: EUS-BD may be an option for patients with altered anatomy after a failed endoscopic-retrograde-cholangiography in centers with expertise in EUS-BD procedures in a research setting.
