The motility change after per-oral endoscopic myotomy (POEM) in achalasia is currently focused on lower esophageal sphincter (LES). This study aims to investigate the correlation of motility response between distal and proximal esophagus after POEM.

Diagnosis of esophageal diseases is often hampered by sampling errors that are inherent in endoscopic biopsy, the standard of care. Spectrally encoded confocal microscopy (SECM) is a high-speed reflectance confocal endomicroscopy technology that has the potential to visualize cellular features from large regions of the esophagus, greatly decreasing the likelihood of sampling error. In this paper, we report results from a pilot clinical study imaging the human esophagus in vivo with a prototype SECM endoscopic probe.

Cervical esophageal cancer (CEC) is a less common form of cancer and often locally advanced at the time of diagnosis; thus, survival rates for patients with CEC remain poor. However, no reports exist on results of endoscopic submucosal dissection (ESD) for superficial cancer at the cervical esophagus. The aim of this retrospective study was to elucidate the clinicopathological features and clinical outcomes of ESD for superficial CEC.

The survival of the patients with esophageal atresia an tracheo esophageal fistula is believed to be an epitome of the success of the neonatal surgery. Restoring the continuty of the food pipe by esophagus to esophagus anastomosis is the best option. Preservation of natural esophagus by delayed repair in a wide gap esophageal atresia is a preferred technique worldwide, however such a management required prolonged hospitalization and dedicated nursing care, which is often not available in most of the centres in India. Esophageal substitutes in wide gap requires multiple operations and have long term problems, so remains the last option. I use the technique of oblique anastomosis which had distrinct advantage over circular anastomosis in the management of esophageal atresia1. This techniqe helps in bridging wide gap to some extent & minimal stricture formation.

Giant fibrovascular esophageal polyps are rare benign intraluminal tumors that originate from the submucosa of the cervical esophagus [Owens et al. (JAMA 103: 838-842, 1994), Totten et al. (JAMA 25:606-622, 1953)]. Due to their indolent course, these tumors tend to reach enormous proportions before patients develop symptoms. Accurately diagnosing these tumors is difficult, as endoscopy may miss 25% of these lesions because these polyps exhibit normal intact esophageal mucosa [Levine et al. (JAMA 166: 781-787, 1996)].

The indications of esophageal replacement (ER) in pediatric patients include long gap esophageal atresia (LGEA), intractable post-corrosive esophageal strictures (PCES), and some rare esophageal diseases. Various conduits and procedures are currently used worldwide with a lack of consensus regarding the ideal substitute to replace the esophagus replacement. The short-term outcomes of these advanced procedures are well known; there are few data available describing long-term functional outcomes of these patients with long life expectancy.

Peroral endoscopic myotomy (POEM) is a new efficacious treatment option for achalasia. We propose to define “esophageal remodeling” as the functional restoration of the esophagus that involves decreased lower esophageal sphincter (LES) pressure, recovery of esophageal body peristalsis, and reduction of luminal diameter. The aim of this study was to investigate “esophageal remodeling” after POEM for achalasia.

Current methods of obtaining esophageal cytology include brush biopsy and blind balloon sampling, among others. These methods can be time-consuming if performed in accordance with acknowledged standards. Further, exact site localization can prove to be difficult. We describe a novel device for esophageal sampling using an esophageal balloon with debriding strips contained within the pleats of the balloon. Inflation brings the latter in contact with the surface to be sampled. Cell capture was compared with the commonly used brush technique in a pig model.

Self-expandable metallic stent (SEMS) placement is effective for dysphagia that results from malignant obstruction of the esophagus or gastric cardia; however, stent-related complications may be life-threatening. Thus, the goal of this study was to identify risk factors associated with complications following esophageal stenting.
