BACKGROUND: The reconstruction of hepatic artery (HA) is most complex step in living donor liver transplantation (LDLT) due to smaller diameter of the artery and increased risk of HA related complications. Due to smaller diameter of the HA, many centres use microsurgical technique with interrupted sutures for arterial anastomosis. Aim of our study was to retrospectively investigate the outcomes after HA reconstruction performed under magnifying loupes using "parachute technique". MATERIALS AND METHODS: From August 2002 to 31(st) August 2016, LDLT was performed in 766 recipients...

BACKGROUND: Photochemical tissue bonding (PTB) is a sutureless, light-activated technique that produces a watertight, microvascular repair with minimal inflammation compared to standard microsurgery. However, it is practically limited by the need for a clinically viable luminal support system. The aim of this study was to evaluate a hollow biocompatible stent to provide adequate luminal support to facilitate vascular anastomosis using the PTB technique. METHODS: Forty rats underwent unilateral femoral artery transection...

Transanal endoscopic surgery (TES) techniques encompass a variety of approaches, including transanal endoscopic microsurgery and transanal minimally invasive surgery. These allow a surgeon to perform local excision of rectal lesions with minimal morbidity and the potential to spare the need for proctectomy. As understanding of the long-term outcomes from these procedures has evolved, so have the indications for TES. In this study, we review the development of TES, its early results, and the evolution of new surgical techniques...

Bench model hands-on learning may be more effective than traditional didactic practice in some surgical fields. However, this has not been reported for microsurgery. Our study objective was to demonstrate the efficacy of bench model hands-on learning in acquiring microsuturing skills. The secondary objective was to evaluate the aptitude for microsurgery based on personality assessment. Eighty-six medical students comprising 62 men and 24 women were randomly assigned to either 20 min of hands-on learning with a bench model simulator or 20 min of video-learning using an instructional video...

BACKGROUND: The endoscopic technique has been recognised as a viable and safe alternative to microsurgery for the treatment of third-ventricle colloid cyst. However, the standard precoronal endoscopic approach does not always provide an adequate visualisation of the attachment of the cyst to the velum interpositum. Using a more anterior approach, it is easier to reach the roof of the cyst and its possible adherences with the tela choroidea. METHOD: The authors describe step by step the anterior trans-frontal endoscopic approach for management of third ventricle colloid cyst...

The treatment of adult osteonecrosis of the femoral head (ONFH), with 8.12 million patients in China, remains a challenge to surgeons. To standardize and improve the efficacy of the treatment of ONFH, Chinese specialists updated the experts' suggestions in March 2015, and an experts' consensus was given to provide a current basis for the diagnosis, treatment and evaluation of ONFH. The current guideline provides recommendations for ONFH with respect to epidemiology, etiology, diagnostic criteria, differential diagnosis, staging, treatment, as well as rehabilitation...

PURPOSE OF REVIEW: To give an overview of the evolvement of transoral laser microsurgery (TLM) in the treatment of early glottic carcinoma and highlight the contribution of recent literature. RECENT FINDINGS: The indications and limits of TLM have been well specified. Effects on swallowing have been well documented. Introduction of narrow-band imaging (NBI) and diffusion-weighted magnetic resonance has been shown of additional value for outcome. The first reports on transoral robotic surgery show that it may be of added value in the future...

PURPOSE: In recent years, the indications of latissimus dorsi myocutaneous flap decreased in favor of its version preserving muscle: the thoracodorsal artery perforator flap (TDAP). The intramuscular dissection reduce donor site morbidity but also allows an extension of the pedicle compared to conventional latissimus dorsi flap pedicle. The purpose of this study was to quantify objectively elongation of the pedicle when the perforator is dissected through the muscle. METHOD: Sixteen TDAP flap were dissected in 9 cadavers...

We present two minimally invasive microsurgical techniques in rodents for specific drug delivery into the middle ear so that it may reach the inner ear. The first procedure consists of perforation of the tympanic bulla, termed bullostomy; the second one is a transtympanic injection. Both emulate human clinical intratympanic procedures. Chitosan-glycerophosphate (CGP) and Ringer´s Lactate buffer (RL) were used as biocompatible vehicles for local drug delivery. CGP is a nontoxic biodegradable polymer widely used in pharmaceutical applications...
