Abstract Background and Aim Idiopathic achalasia is a rare esophageal motor disorder. The disease state manifests local systemic inflammation, it appears that an autoimmune component specific autoantibodies participate in the pathogenesis. study aims to determine prevalence of chronic inflammatory diseases patients with compare results those from gastroesophageal reflux (GERD). Methods It was cross‐sectional included 114 idiopathic age‐matched sex‐matched control GERD. Data on presence...

Idiopathic achalasia is a relatively infrequent esophageal motor disorder for which major histocompatibility complex (MHC) genes are well-identified risk factors. However, no information about HLA-achalasia susceptibility in Mexicans has previously been reported. We studied group of 91 patients diagnosed with and 234 healthy controls Mexican admixed ancestry. HLA alleles conserved extended haplotypes were analyzed using high-resolution typing based on Sanger next-generation sequencing...

Long-term dietary and pharmacological treatments for obesity have been questioned, particularly in individuals with severe obesity, so a new approach may involve adipose tissue transplants, autologous transplants. Thus, the aim of this study was to evaluate metabolic effects subcutaneous (SAT) transplants into two specific intraabdominal cavity sites (omental retroperitoneal) after 90 days. The performed using different diet-induced (DIO) rat models: one high-fat diet (HFD) other...

The aim of the study was to characterize presence diverse CD4 and CD8 T cell subsets regulatory cells in peripheral blood lower oesophageal sphincter (LES) from a young patient with BE/achalasia without treatment versus achalasia group. In order circulating this patient, cytometric analysis performed. LES tissue evaluated by double-immunostaining procedure. Five healthy donors, 5 type patients, oesophagus samples (gastrooesophageal junction) transplant donors were included as control groups....

De-novo malignancies carry an incidence ranging between 3%-26% after transplant and account for the second highest cause of post-transplant mortality behind cardiovascular disease. While majority de-novo usually consist skin cancers, there has been increasing rate solid tumor cancers over last 15 years. Although, recurrence hepatocellular carcinoma (HCC) is well understood among patients transplanted HCC, are reports HCC in those a non-HCC indication. The proposed pathophysiology these cases...

Introduction: Achalasia is a chronic motility disorder of the esophagus with difficult to manage symptoms. Despite multi-modal therapies, some patients progress end-stage disease requiring esophagectomy. Quality life (QOL) has not been fully described in this population. Methods: A cross-sectional QOL study was performed on cohort achalasia who underwent an esophagectomy (2010-2020). Patients met inclusion criteria were contacted by phone 2021 complete GIQLI and OES-18 questionnaires....

Background: Surgical outcomes after minimally invasive esophagectomy (MIE) for patients with end-stage achalasia are limited. This study presents a case series of who underwent MIE at high-volume institution and review the literature. Methods: We conducted retrospective single academic from 2010 to 2019. Patients were included. Descriptive statistics demographics as well 90-day surgical (length stay, readmission, reoperation, overall complications, mortality) Results: A total 16 during...
