A 75-year-old man previously presented with gastric outlet obstruction caused by a pyloric peptic stricture, which did not respond to balloon dilation. He required surgical treatment with a Roux-en-Y reconstruction in 2011. Four years later, he presented an episode of cholecystitis, and an open partial cholecystectomy was performed after discovery of gallbladder empyema. Postoperative biliary l...

Mirizzi's syndrome (MS) is a rare complication of the inveterate biliary lithiasis. Diagnostic and therapeutic standardization is still missing, especially since laparoscopic cholecystectomy has become the gold standard approach for symptomatic cholelithiasis. Our study is a retrospective analysis based on a case-series. It considered 370 cholecystectomies performed from 2006 to 2011. We select...

BACKGROUND Breast surgical site infections (SSIs) are major sources of postoperative morbidity and mortality, and it's established that surveillance of risk factors is effective in reducing hospital-acquired infections. However, studies about risk factors for breast SSIs were still under controversy because of limited data, contradictory results and lack of uniformity. MATERIALS AND METHODS W...

OBJECTIVE The aim of this study is to perform a comprehensive evaluation of 5 years of experience with the technique of isolated pancreatic anastomosis reconstruction after pancreatoduodenectomy from the perspective of safety and surgical efficacy using a prospective database. METHODS The study included all consecutive patients undergoing pancreatoduodenectomy from April 2009 to April 2014 at...

Magnetic compression anastomosis (MCA) has been developed as a non-surgical alternative treatment for biliary obstruction without serious complications. A 70-year-old woman who had undergone pancreaticoduodenectomy with modified Child reconstruction for pancreatic head cancer suffered from obstructed choledochojejunostomy with no recurrent findings 4 months after the operation. Cholangiography ...

Superior vena cava (SVC) syndrome is a group of clinical signs caused by the obstruction or compression of SVC and characterized by edema of the head, neck, and upper extremities, shortness of breath, and headaches. The syndrome may be caused by benign causes but most of the cases are caused by lung or mediastinal malignant tumors. Stenting of SVC has become widely accepted as the palliative tr...

OBJECTIVE We present our experience in the reconstruction of cerebrospinal fluid (CSF) leaks according to their size and location. MATERIAL AND METHODS Fifty-four patients who underwent advanced skull base surgery (large defects) and 62 patients with CSF leaks of different origin (small and medium-sized defects) were included. Large defects were reconstructed with a nasoseptal pedicled flap p...

INTRODUCTION When recipient veins for free-flap breast reconstruction are unavailable or inadequate, vein grafts or cephalic vein transposition (CVT) an option to provide alternate venous outflow. There are no comparative data to elucidate the indications and outcomes for each. We hypothesize that the CVT is as reliable as vein grafts when indicated. METHODS All consecutive cases where a CVT ...

The research in the fields of irrigation and drainage network in the province Hamidieh to evaluate the performance of drainage was done in the land. For this purpose, three drainage server farm at intervals of 50, 70 and 80 meters in the area was selected. Blank observation on three drain pipes at intervals of 0.3,0.8,1.5,2.5 and 15 meters of lateral drains in the middle of the line in four row...

The Multiscale Finite-Volume (MSFV) method has been recently developed and tested for multiphase-flow problems with simplified physics (i.e. incompressible flow without gravity and capillary effects) and proved robust, accurate and efficient. However, applications to practical problems necessitate extensions that enable the method to deal with more complex processes. In this paper we present a ...
