BACKGROUND The aim of this study is to compare the short-term results between robotic-assisted low anterior resection (R-LAR), using the da Vinci Surgical System, and standard laparoscopic low anterior resection (L-LAR) in rectal cancer patients. METHODS 113 patients were assigned to receive either R-LAR (n = 56) or L-LAR (n = 57) between April 2006 and(More)
BACKGROUND The purpose of this study is to review the clinical outcomes of patients who received extended lymph node dissection for radiologically diagnosed extramesenteric lymph node metastasis. PATIENTS AND METHODS The authors reviewed clinical characteristics, short-term operative outcomes, and long-term oncologic outcomes of 151 patients who had(More)
Parkinson's disease (PD) is the second most common progressive neurodegenerative disease. Several genes have been associated with familial type PD, providing tremendous insights into the pathogenesis of PD. Gathering evidence supports the view that these gene products may operate through common molecular pathways. Recent reports suggest that many(More)
We have introduced both electrophoretic and dynamic light scattering to evaluate the polydispersity, nanodispersity, and stability of single-walled carbon nanotubes (SWNTs) in distilled water with surfactants. By controlling the sodium dodecyl sulfate composition and some pretreatment by sonication, we were able to achieve nanodispersion (dispersion into(More)
PURPOSE To evaluate the predictive value of the early response of (18)F-flurodeoxyglucose positron emission tomography (FDG PET) during concurrent chemoradiotherapy (CCRT) for locally advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS FDG PET was performed before and during CCRT for 13 NSCLC patients. Maximum standardized uptake value(More)
PURPOSE The aim of this study was to determine the correlation between tumor volume changes assessed by three-dimensional (3D) magnetic resonance (MR) volumetry and the histopathologic tumor response in rectal cancer patients undergoing preoperative chemoradiation therapy (CRT). METHODS AND MATERIALS A total of 84 patients who underwent preoperative CRT(More)
BACKGROUND Few studies have focused on distribution of lymph node metastasis. The aim of this study is to evaluate the prognostic significance of the location of involved lymph nodes in patients with advanced mid or low rectal cancer. METHODS We defined proximal lymph node involvement (PLNp) as superior rectal and inferior mesenteric lymph node metastasis(More)
BACKGROUND The increase in drug-resistant bacteria and the ban on antibiotic growth promoters worldwide make the search for novel means of preventing bacterial infection and promoting growth performance imperative. In this sense, antimicrobial peptides are thought to be ideal candidates owing to their antimicrobial properties, broad spectrum of activity and(More)
BACKGROUND Laparoscopic rectal transection carries the risk of anastomotic leakage because of its technical difficulty and long staple line with an inadequate cutting angle. Our objective was to investigate the risk factors affecting anastomotic leakage after laparoscopic intracorporeal colorectal anastomosis with a double stapling technique. STUDY DESIGN(More)
BACKGROUND Self-expanding metallic stents (SEMS) have been used as a bridge to surgery in patients with obstruction by colorectal cancer, but the oncologic safety of this technique has not yet been established. The aim of the present study was to compare the outcomes of bridge to surgery after SEMS insertion and nonobstructing elective surgery. METHODS(More)
