Laparoscopic laterally extended endopelvic resection procedure for gynecological malignancies

2020

ObjectivesPelvic side wall infiltration by gynecological malignancies has been considered for a long time an absolute contraindication to curative resection. The development of the laterally extended endopelvic resection (LEER) has challenged this surgical paradigm. Although the LEER has been standardized in open surgery, only small studies have been published about its endoscopic feasibility. The objective of this study is to analyze the safety of LEER in patients with gynecological malignancies involving the pelvic side wall.MethodsWe retrospectively evaluated a consecutive series of patients who underwent a laparoscopically modified LEER between July 2014 and November 2018. This indicate…

Small-diameter hysteroscopy with Versapoint versus resectoscopy with a unipolar knife for the treatment of septate uterus: A prospective randomized s…

2007

Abstract Study objective To compare 2 procedures for metroplasty: resectoscopy with monopolar knife versus small-diameter hysteroscopy fitted with a Versapoint device. Design Prospective randomized study (Canadian Task Force classification I). Setting Endoscopic gynecology units at tertiary care university hospitals. Patients One hundred-sixty patients with septate uterus and a history of recurrent abortion or primary infertility undergoing hysteroscopic metroplasty from 2001 to 2005. Interventions Hysteroscopic resection of the uterine septum performed with either a 26F resectoscope with unipolar knife (80 women, group A) or a 5-mm diameter hysteroscope with Versapoint device (80 women, gr…

Biportal neuroendoscopic microsurgical approaches to the subarachnoid cisterns. A cadaver study.

1996

A preclinical cadaver study was performed to develop the technique of biportal neuroendoscopic dissection in the subarachnoid space of the basal cisterns and to test the feasibility, utility, and safety of this new technique. In 23 fresh post-mortem adult human cadavers and 2 formalin-fixed adult human head specimen a total of 33 biportal endomicrosurgical dissections into and within the basal cisterns were carried out. Following suction of cerebrospinal fluid from the subarachnoid space 0 degree-, 30 degrees-, and 70 degrees-lens-scopes (Aesculap AG, Tuttlingen, Germany) with outer diameters of 4.2 mm and trochars with outer diameters of 5 to 6.5 mm were introduced into the surgical field.…

Chimney and periscope grafts to facilitate endovascular treatment of aortic transection in a patient with aberrant right subclavian artery

2014

Purpose: To report the use of parallel grafts to extend the proximal landing zone for stentgraft repair of aortic transection involving an aberrant right subclavian artery (ARSA). Case Report: A 28-year-old patient was referred for treatment of traumatic aortic transection with contained rupture at the level of an ARSA. Immediate thoracic endovascular aortic repair (TEVAR) was planned because of hemodynamic instability. To achieve rapid sealing and maintain perfusion to both subclavian arteries, a chimney stent to the left subclavian artery (LSA) and a periscope stent-graft to the ARSA were deployed successfully. After surgical repair of all fractures, the patient was discharged 1 month aft…

Resectoscope versus small diameter hysteroscopy for endometrial polypectomy in patients with "unfavorable" cervix

2017

BACKGROUND: The aim of this study was to compare resectoscopic and small-diameter hysteroscopic techniques for endometrial polypectomy in patients with "unfavorable" cervix.METHODS: Eighty women with a single 2-4 cm sized endometrial polyp, with unfavorable cervical anatomical conditions were enrolled in the study. Forty patients were treated with a 26F resectoscope requiring cervical dilatation (group A), forty patients were treated with a 5-mm hysteroscope requiring vaginoscopic approach (group B). Operative time, fluid absorption, complications, instrument failure, postoperative pain, overnight stay were analyzed. Operative visualization, operative difficulty and overall surgeon's satisf…

Laparoscopic aortic lymphadenectomy in left-sided inferior vena cava

2020

Transposition of the inferior vena cava (IVC), also known as left-sided IVC (LS-IVC), is a rare congenital variant which results from regression of the right supracardinal vein and persistence of the left supracardinal vein in embryonic development.[1 2][1] LS-IVC occurs in 0.2–0.5% of the general

The flaring afterglow of GRB 050730

2006

We present a detailed spectral and temporal analysis of Swift and XMM-Newton observations of GRB 050730. The X-ray afterglow of GRB 050730 was found to decline with time with intense flaring activity superimposed. Evidence of flaring activity in the early UVOT optical afterglow, simultaneous with that observed in the X-ray band, was found. Strong spectral evolution in the X-ray energy band during the flaring activity was present.

The Catalonian Conflict : an Interpretive Structural Model

2019

The methodology ISM (Interpretive Structural Modeling) is used to study the conflict in Catalonia, listing a list of factors and the influences between them, building from them the Matrix of Influences and the Matrix of Scope, from which they classify the factors into levels and a flow diagram is drawn up, concluding what the possible paths of evolution of said conflict would be

Preferential localization of Lactococcus lactis cells entrapped in a caseinate/alginate phase separated system.

2013

International audience; This study aimed to entrap bioprotective lactic acid bacteria in a sodium caseinate/sodium alginate aqueous two-phase system. Phase diagram at pH = 7 showed that sodium alginate and sodium caseinate were not miscible when their concentrations exceeded 1% (w/w) and 6% (w/w), respectively. The stability of the caseinate/alginate two-phase system was also checked at pH values of 6.0 and 5.5. Lactococcus lactis subsp. lactis LAB3 cells were added in a 4% (w/w) caseinate/1.5% (w/w) alginate two-phase system at pH = 7. Fluorescence microscopy allowed to observe that the caseinate-rich phase formed droplets dispersed in a continuous alginate-rich phase. The distribution of …
