CMAJ • FEBRUARY 8, 2011 • 183(2) © 2011 Canadian Medical Association or its licensors E132 A61-year-old woman presented with intermittent abdominal discomfort, which had been present for several weeks. She reported sometimes feeling better in the supine position than in the erect position. She had no relevant medical or family history and she took no medications. Physical examination showed a d...

background: the gold standard of the management of rectal cancer in the middle and lower parts is low anterior resection with coloanal anastomosis. about 50% of the patients undergoing this procedure might experience some complications because of the low capacity of the neorectum. the aim of this study was to evaluate ileal j-pouch interposition as a neorectum between the anal canal and the rem...

Many reports have been published on complications related to middle cerebral artery (MCA) aneurysm surgical clipping procedures. We report an emergency intracranial in situ bypass surgery case which was performed as a rescue procedure after aneurysmal neck laceration during clipping of an MCA large aneurysm. In this case, we performed in situ M3-superficial temporal artery (STA) interposition g...

This report focuses on iatrogenic transmesocolic hernia causing small bowel obstruction following colonic interposition. Of 45 patients undergoing visceral esophageal substitution using colon, three developed small bowel obstruc. tion due to internal herniation of a loop of small boweI through a defect in the mesocolon. Awareness of this unique cause of small bowel obstruction following colonic...

A patient with friable hepatic artery and poor hepatic arterial inflow, portal vein thrombosis and serious gastroesophageal varices underwent modified piggyback liver transplantation. The hepatic artery was reconstructed by interposing donor’s iliac arterial conduit anastomosed to the infrarenal aorta, while the portal vein flow was ensured by the interposition of donor’s iliac venous graft. Th...

INTRODUCTION Cholesteatoma is traditionally diagnosed by otoscopic examination and treated by surgery. The necessity for imaging in an uncomplicated case is controversial. This study was planned to investigate the usefulness of a preoperative high-resolution computed tomography (HRCT) scan in depicting the status of middle ear structures in the presence of cholesteatoma and also to compare the ...

Introduction  Chronic otitis media can cause multiple middle ear pathogeneses. The surgeon should be aware of relation between ossicular chain erosion and other destructions because of the possibility of complications. Objective  This study aimed to investigate the rates of ossicular erosion in cases of patients with and without facial nerve canal destruction, who had undergone mastoidectomy du...

The aim of the study was to describe ossicle resorption in chronic otitis with cholesteatoma and correlate it with clinical parameters such as age, contralateral ear condition, tympanic membrane aspect, cholesteatoma pathogenesis and extension, associated lesions and hearing threshold. Preoperative clinical data were collected for 140 patients with chronic otitis with cholesteatoma, whose ossic...

The use of genetically modified mice can accelerate progress in auditory research. However, the fundamental profile of mouse hearing has not been thoroughly documented. In the current study, we explored mouse middle ear transmission by measuring sound-evoked vibrations at several key points along the ossicular chain using a laser-Doppler vibrometer. Observations were made through an opening in ...

Introduction The human auditory system includes the hearing and balance organs, and can be divided into three main elements: outer ear, middle ear and inner ear. The auditory ossicles are three very small bones: the malleus, incus and stapes, confined in the middle ear and coupled in chain. Their main function is to transmit sound energy from the tympanic membrane to the fluid-filled cochlea. A...
