Most of the esophageal squamous cell carcinomas (ESCCs) and cancers head neck (H&N) region are diagnosed at later stages. To achieve better survival, early detection is necessary. We compared real-time diagnostic yield superficial cancer in these regions between conventional white light imaging (WLI) narrow band (NBI) high-risk patients.In a multicenter, prospective, randomized controlled trial, 320 patients with ESCC were randomly assigned to primary WLI followed by NBI (n = 162) or 158)...
Background: Endoscopic mucosal resection (EMR) is a recognized treatment for early gastric cancer (EGC). One‐piece considered to be gold standard of EMR, as it provides accurate histological assessment and reduces the risk local recurrence. submucosal dissection (ESD) new technique developed obtain one‐piece even large ulcerative lesions. The present study aims identify technical feasibility, operation time complications from consecutive series. Methods: We reviewed all patients with EGC who...

Some patients develop multiple squamous cell carcinomas (SCCs) in the upper aerodigestive tract, attributed to field cancerization; alcohol consumption has been associated with this process. We examined association between areas of dysplastic epithelium development SCC esophagus or head and neck cancer, as well smoking.We 331 early stage esophageal using Lugol chromoendoscopy evaluate esophagus. Patients then were assigned 3 groups, based on number Lugol-voiding lesions: A, no lesion; B, 1-9...
Background & AimsEsophagectomy is the standard treatment for stage I esophageal squamous cell carcinoma (ESCC). We conducted a single-arm prospective study to confirm efficacy and safety of selective chemoradiotherapy (CRT) based on findings from endoscopic resection (ER).MethodsWe performed patients with T1b (SM1–2) N0M0 thoracic ESCC December 2006 through July 2012; 176 underwent ER. Based ER, received following: no additional pT1a tumors negative margin lymphovascular invasion (group A);...
Background and Purpose— We sought to investigate cerebral mechanisms underlying locomotor recovery after stroke. Methods— measured cortical activities during hemiparetic gait on the treadmill before 2 months of inpatient rehabilitation in 8 patients with initial stroke (5 men, 3 women; 4 right left hemiparesis; aged 57 years; average), using an optical imaging system. Results— On evaluation, was associated increased oxygenated hemoglobin levels medial primary sensorimotor cortex (SMC) that...
We investigate whether the functional near-infrared spectroscopic (fNIRS) signal includes a from changing skin blood flow. During locomotor task on treadmill, changes in hemodynamic response front-parietal area of healthy human subjects are simultaneously recorded using an fNIRS imaging system and laser Doppler tissue flow meter. Independent component analysis (ICA) for signals is performed. The during tasks treadmill. activated spatial distribution one components separated by ICA reveals...
Abstract Cortical activation during hemiplegic gait was assessed in six nonambulatory patients with severe stroke (four men, two women; four right and left hemiplegia; 57 years old 3 months after on average), using a near‐infrared spectroscopic imaging system. Each patient performed tasks of treadmill walking (0.2km/hr), alternated rest every 30 seconds for repetitions, under partial body weight support, either mechanical assistance swinging the paretic leg control (CON) or facilitation...
<b>Background and study aims:</b> Compared with any other location in the gastrointestinal tract, duodenum presents most challenging site for endoscopic resection. The aim of this was to analyze clinical outcomes duodenal resection assess feasibility technique as a therapeutic procedure. <b>Patients methods:</b> A total 113 consecutive patients 121 nonampullary tumors underwent by submucosal dissection (ESD), mucosal (EMR), or polypectomy between January 2000 September 2013. Long-term were...
Intramucosal undifferentiated early gastric cancer (EGC) up to 2 cm in size without ulceration has been treated by endoscopic submucosal dissection (ESD) because the incidence of lymph node metastasis is negligible. The aim this retrospective study was clarify short-term and long-term outcomes ESD carried out treat EGC.Between January 1999 September 2011, 113 patients with poorly differentiated adenocarcinoma or signet ring cell carcinoma on preoperative biopsy underwent ESD. In 16 EGC had...
Background and Aim: There have been few previous reports on endoscopic submucosal dissection (ESD) learning curve for early gastric cancer (EGC) so we retrospectively assessed this subject based experience of our trainees. Methods: Trainees in center start performing ESDs lesions lower third stomach with hands‐on support by experts during first 10 cases then perform themselves primarily verbal guidance from experts. They are gradually assigned to middle upper thirds stomach. From January...
