BACKGROUND A right-sided hepatectomy with total caudate lobectomy is indicated for colorectal-cancer liver metastases (CLM) and hepatocellular carcinomas (HCC) located in the caudate lobe with extension to the right lobe of the liver. Caudate-lobe resection (i.e. segmentectomy 1 according to the Brisbane terminology) is one of the most difficult types of hepatectomy to carry out radically and s...

The recovery of soleus (SOL), gastrocnemius (GAS), and tibialis anterior (TA) electromyographic activity (EMG) after transection and surgical repair of the sciatic nerve was studied in Sprague-Dawley rats using chronically implanted stimulation and recording electrodes. Spontaneous EMG activity in SOL and GAS and direct muscle (M) responses to posterior tibial nerve stimulation persisted for < ...

Previous studies have shown that corticospinal tract (CST) transection, but not transection of other major spinal cord tracts, prevents down-conditioning of the H-reflex, the electrical analog of the spinal stretch reflex. This study set out to determine whether the loss of the capacity for H-reflex down-conditioning caused by CST transection is permanent. Female Sprague-Dawley rats received CS...

BACKGROUND The purpose of this study was to design and make a simple, inexpensive brain knife that could produce consistent results following transection in animal model. MATERIALS AND METHODS After testing various materials including commercially available products, microelectrode recording needles as used in deep brain stimulation (DBS) surgery were selected as ideal candidates. They were m...

Hair transplantation involving patients with tightly curled Afro-textured hair using follicular unit extraction (FUE) employing conventional rotary punches frequently leads to unacceptably high transection rates. These patients are unsuitable candidates for FUE hair transplantation. Transection rates were observed during FUE in a case series of 18 patients with tightly curled Afro-textured hair...

Background Ascending testis (AT) is one of the rare but serious complication that may occurs following inguinal hernia/hydrocele repair. We aimed to review our more than 7 years’ experience and discuss the possible mechanism through which the AT possibly occurs following inguinal hernia/hydrocele repair. Materials and Methods A retrospective analysis of 7,212 boys who had undergone inguinal her...

Background: Axotomy causes sensory neuronal loss. Reconnection of proximal and distal nerve ends by surgical repair improves neuronal survival. It is important to know the morphology of primary sensory neurons after the surgical repair of their peripheral processes. Methods: Animals (male Wistar rats) were exposed to models of sciatic nerve transection, direct epineurial suture repair of sciati...

Burroughs, A.K., Hamilton, G. Phillips, A., Mezzanotte, G., Mclntyre, N. and Hobbs, K.E.F. (1989) A comparison of sclerotherapy with staple transection of the esophagus for the emergency control of bleeding from esophagus varices. The New England Journal of Medicine; 321:857-862 We compared two procedures for the emergency treatment of bleeding esophageal varices in patients who did not respond...

BACKGROUND Retinal ganglion cells (RGCs) die in sight-threatening eye diseases. Imaging RGCs in humans is not currently possible and proof of principle in experimental models is fundamental for future development. Our objective was to quantify RGC density and retinal thickness following optic nerve transection in transgenic mice expressing cyan fluorescent protein (CFP) under control of the Thy...
