Synaptophysin, or p38, a polypeptide of molecular weight 38 kD, is a calcium-binding membrane protein found in synaptic vesicles of neurons and smooth surfaced vesicles of neuroendocrine cells. Six human neonatal and infant temporal bones were fixed in paraformaldehyde and glutaraldehyde, decalcified in EDTA and were than immunoreacted for synaptophysin(More)
PURPOSE This study aimed to compare the learning curves and early postoperative outcomes for conventional laparoscopic (CL) and single incision laparoscopic (SIL) right hemicolectomy (RHC). METHODS This retrospective study included the initial 35 cases in each group. Learning curves were evaluated by the moving average of operative time, mean operative(More)
The lengths of the surgical rectum and peritoneal reflection were important factors in treatment modality of rectal tumor. To evaluate the surgical length of rectum, we measured the length of the peritoneal reflections, sacral promontory and termination of the taenia coli from the anal verge by rigid sigmoidoscope in 23 male and 23 females during operation.(More)
PURPOSE Oxaliplatin-induced chronic peripheral neurotoxicity (OXCPN) manifests as a loss of sensation and dysesthesia in the distal extremities, which may impair daily activities and increase in incidence with the amount of oxaliplatin delivered. The variation in the reported incidence and severity of OXCPN may be a consequence of differences in the(More)
PURPOSE Although anemia is considered to be a contributor to intra-tumoral hypoxia and tumor resistance to ionizing radiation in cancer patients, the impact of pretreatment anemia on local control after neoadjuvant concurrent chemoradiotherapy (NACRT) and surgery for rectal cancer remains unclear. MATERIALS AND METHODS We reviewed the records of 247(More)
PURPOSE Recently, an increase in well-differentiated rectal neuroendocrine tumors (WRNETs) has been noted. We aimed to evaluate transanal endoscopic microsurgery (TEM) for the treatment of WRNETs. METHODS Between December 1995 and August 2009, 109 patients with WRNETs underwent TEM. TEM was performed for patients with tumors sizes of up to 20 mm and(More)
PURPOSE An anorectal melanoma (AM) is a very rare tumor. However, sufficient data supporting effective surgical options for the disease do not exist. This retrospective review aimed to analyze treatment outcomes for an AM. METHODS From June 1999 to December 2008, we retrospectively reviewed a prospectively collected consecutive series of 19 patients who(More)
Mucinous adenocarcinoma (MAC) is a histological subtype of colorectal cancer. The oncologic behavior of MAC differs from nonmucinous adenocarcinoma (non-MAC). Our aim in this study was to characterize patients with colorectal MAC through evaluation of a large, institutional-based cohort with long-term follow-up. A total of 6475 patients with stages I to III(More)
OBJECTIVES Autologous costal cartilage is a promising alternative for mastoid obliteration. However, donor-site morbidities of the chest wall limit the use of this graft. To address this issue, we have developed a minimally-invasive technique of harvesting costal cartilage and report donor site morbidity associated with the procedure. METHODS Donor site(More)
