Mucosal Congestion on the First Day Following Endoscopy Predicts Anastomotic Stricture After Esophagectomy.

Background: Anastomotic stricture is a relatively common postoperative complication after esophagectomy. Previous studies have indicated that impaired perioperative blood perfusion at the anastomosis is associated with the occurrence of stricture. Therefore, we analyzed the association between endoscopically assessed blood perfusion during the early postoperative period and anastomotic stricture.

A feasibility study of mediastinoscopic radical esophagectomy for thoracic esophageal cancer from the viewpoint of the dissected mediastinal lymph nodes validated with thoracoscopic procedure: a prospective clinical trial.

Purpose: A prospective trial evaluated the feasibility and safety of "mediastinoscopic esophagectomy with lymph node dissection" (MELD).

Methods: Eligible patients had thoracic esophageal squamous cell carcinoma, excluding T4, a bulky primary lesion or distant metastasis. Ten patients were enrolled and treated between September 2015 and March 2018.

Detection of Second Primary Malignancies of the Esophagus and Hypophraynx in Oral Squamous Cell Carcinoma Patients.

Objective: To assess the usefulness of modified esophagogastroduodenoscopy (EGD) for the detection of second primary malignancies of the esophagus or hypopharynx in patients with oral squamous cell carcinoma and determine the association between the oral lesion subsite and esophageal or hypopharyngeal lesion occurrence.

Study Design: Retrospective review.

Methods: In total, 166 patients with oral squamous cell carcinoma without any established symptoms of esophageal or hypopharyngeal squamous cell carcinoma underwent modified EGD based on the Valsalva maneuver and U-turn method, image-enhanced endoscopy, and chromoendoscopy using Lugol's iodine for diagnosis.

Histological study of the thin membranous structure made of dense connective tissue around the esophagus in the upper mediastinum.

Background: The structure of the fascia in upper mediastinum has already been reported from gross anatomical viewpoints by Sarrazin. But it is necessary to understand meticulous anatomy for thoracoscopic or mediastinoscopic surgery. So herein, we investigate histologically the thin membranous structure made of dense connective tissues.

[Evaluation of Bevacizumab in Combination with Weekly Paclitaxel for Locally Advanced Breast Cancer].

Locally advanced breast cancer that exhibits bleeding, has a foul odor, and expresses an exudate often reduces the quality of life(QOL). Bevacizumab(Bv)in combination with weekly paclitaxel(PTX)therapy has a high response rate. To date, we have used this combination for 8 cases of locally advanced breast cancer in our hospital.

Visualization Method for Proprioceptive Drift on a 2D Plane Using Support Vector Machine.

Proprioceptive drift, which is a perceptual shift in body-part position from the unseen real body to a visible body-like image, has been measured as the behavioral correlate for the sense of ownership. Previously, the estimation of proprioceptive drift was limited to one spatial dimension, such as height, width, or depth. As the hand can move freely in 3D, measuring proprioceptive drift in only one dimension is not sufficient for the estimation of the drift in real life situations.

The mirror illusion: does proprioceptive drift go hand in hand with sense of agency?

Vection can be regarded as the illusion of "whole-body" position perception. In contrast, the mirror illusion is that of "body-part" position perception. When participants viewed their left hands in a mirror positioned along the midsaggital axis while moving both hands synchronously, they hardly noticed the spatial offset between the hand in the mirror and the obscured real right hand.
