A 73-year-old man with short segmental Barrett's esophagus underwent esophagoscopy, and a slightly depressed, discolored lesion was found on the anterior wall of the lower esophagus. Under a provisional diagnosis of differentiated adenocarcinoma without local lymph node metastasis, endoscopic submucosal dissection (ESD) was carried out. En bloc resection with tumor-free lateral/basal margins wa...

The last three years thirty children with esophageal foreign bodies were admitted Gaziantep SSK Hospital Pediatric Surgery Clinic. mean age 3. 72 in this group. admission time was found to be 36 hours. Coins the most frequently encountered and of at uppcıt esophagus. Esophagoscopy performed all patients as an emergency procedure under general anesthesia.

introduction & objective: foreign body ingestion is a common and important condition that can be life threatening if not diagnosed and treated properly. diagnosis is especially difficult in patients with unusual symptoms. this study was performed to determine the incidence and complications of foreign body ingestion in the patients referred to shiraz khalili hospital. materials & methods: in th...

BACKGROUND High-resolution transnasal esophagoscopy (TNE) allows comprehensive, in-office examination of the esophagus without sedation. OBJECTIVE To compare the authors' present experience using TNE with our initial, previously reported experience. METHODOLOGY Retrospective review of 611 consecutive patients undergoing TNE was compared with 100 consecutive patients previously reported. R...

This paper gives a method to construct rigid spaces, which is similar to the method used to construct toric schemes.

Tensegrity frameworks are defined on a set of points in Rd and consist of bars, cables, and struts, which provide upper and/or lower bounds for the distance between their endpoints. The graph of the framework, in which edges are labeled as bars, cables, and struts, is called a tensegrity graph. It is said to be strongly rigid in Rd if every generic realization in Rd as a tensegrity framework is...

A direction-length framework is a pair (G, p), where G = (V ;D,L) is a ‘mixed’ graph whose edges are labeled as ‘direction’ or ‘length’ edges, and p is a map from V to R for some d. The label of an edge uv represents a direction or length constraint between p(u) and p(v). Let G be obtained from G by adding, for each length edge e of G, a direction edge with the same end vertices as e. We show t...

BACKGROUND There is debate about the optimal voice restoration method and technique for patients who have undergone total laryngopharyngectomy, esophagectomy, and gastric pull-up. The purpose of this study was to report a series of patients who underwent awake, secondary tracheoesophageal puncture (TEP) after this procedure. METHODS A retrospective chart review was performed at a tertiary ref...

An ideal I on a cardinal κ is called rigid if all automorphisms of P (κ)/I are trivial. An ideal is called μ-minimal if whenever G ⊆ P (κ)/I is generic and X ∈ P (μ)V [G] \ V , it follows that V [X] = V [G]. We prove that the existence of a rigid saturated μ-minimal ideal on μ+, where μ is a regular cardinal, is consistent relative to the existence of large cardinals. The existence of such an i...
