PURPOSE The authors evaluate the prevalence of malnutrition and its effect on the postoperative morbidity of patients after surgery for colorectal cancer. METHODS Three hundred fifty-two patients were enrolled prospectively. Nutritional risk screening 2002 (NRS 2002) score was calculated through interview with patient on admission. Clinical(More)
BACKGROUND The purpose of the study was to evaluate the safety and effects of single-incision laparoscopic anterior resection (SILAR) for sigmoid colon cancer by comparing it with conventional laparoscopic anterior resection (CLAR). METHODS Twenty-four patients who underwent SILAR between April 2010 and July 2011 were case matched 1:2 with patients who(More)
Purpose: Hypoxia-inducible factor-1 (HIF-1) primarily α α mediates the hypoxic response. HIF-1 induction by various α stimuli contributes to cell proliferation and survival. To investigate the effect of HIF-1 , we used small interfering RNA α (siRNA), and expected that cell apoptosis and sensitivity to chemotherapeutic drug increase, when we blocked the(More)
PURPOSE The Niti CAR 27 (ColonRing) uses compression to create an anastomosis. This study aimed to investigate the safety and the effectiveness of the anastomosis created with the Niti CAR 27 in a laparoscopic anterior resection for sigmoid colon cancer. METHODS In a single-center study, 157 consecutive patients who received an operation between March(More)
Accurate prediction of regional lymph node metastasis (LNM) in endoscopically resected T1-stage colorectal cancers (CRCs) can reduce unnecessary surgeries. To identify miRNA markers that can predict LNM in T1-stage CRCs, the study was conducted in two phases; (I) miRNA classifier construction by miRNA-array and quantitative reverse transcription PCR(More)
The developments in colon cancer treatment over the past two decades can be found largely in chemotherapy and laparoscopic surgery. Adjuvant chemotherapy increases survival in stage III and select stage II colon cancer patients [1, 2]. Reports in the literature have indicated that delaying the initiation of adjuvant chemother-apy for longer than eight weeks(More)
PURPOSE To investigate the efficacy and safety of the transanal tube (TAT) in preventing anastomotic leak (AL) in rectal cancer surgery. METHODS Clinical data of the patients who underwent curative surgery for mid rectal cancer from February 2010 to February 2014 were reviewed retrospectively. Rectal cancers arising 5 to 10 cm above the anal verge were(More)
tive study is necessary if the use of a patient's own blood as a tattooing method is to become widely accepted as the new standard technique. Furthermore, comparative studies with other new injection materials, such as a pure carbon suspension [8] or iodine-activated indocyanine green [9], may be necessary. This paper proposes a safe and simple method of(More)
Extranigral non-motor signs precede the first motor manifestations of Parkinson's disease by many years in some patients. The presence of α-synuclein deposition within colon tissues in patients with Parkinson's disease can aid in identifying early neuropathological changes prior to disease onset. In the present study, we evaluated the roles of non-motor(More)
