Stretta is a minimally invasive endoscopic procedure for the treatment of gastroesophageal reflux disease (GERD) that delivers radiofrequency energy in the form of electromagnetic waves through electrodes at the end of a catheter to the lower esophageal sphincter (LES) and the gastric cardia – the region of the stomach just below the LES.
The principal objective is to remove the esophagus, a part of the gastrointestinal tract. This procedure is usually done for patients with esophageal cancer. It is normally done when esophageal cancer is detected early, before it has spread to other parts of the body. Esophagectomy of early-stage cancer represents the best chance of a cure.
EndoStim therapy directly targets the weak lower esophageal sphincter (LES) muscle, without altering anatomy or using mechanical constraints. EndoStim's proprietary technology uses functional electrical stimulation (a type of neuromodulation) to restore esophageal function, thereby reducing GERD symptoms. Tiny pulses of electric current are ...
SEMS are used to treat additional complications of cancer, such as tracheoesophageal fistulas from esophageal cancer, [8] and gastric outlet obstruction from stomach, duodenal, or pancreatic cancer. [9] SEMS and self-expanding plastic stents have also been used for non-malignant conditions that cause narrowing or leaks of the esophagus or colon.
Esophageal endoscopic ultrasound can provide staging information regarding the level of tumor invasion, and possible spread to regional lymph nodes. The location of the tumor is generally measured by the distance from the teeth. The esophagus (25 cm or 10 in long) is commonly divided into three parts for purposes of determining the location.
For example, gastroesophageal reflux disease (GERD) with reflux esophagitis is treated with proton pump inhibitors. Esophageal rings or strictures may be treated with esophageal dilation. Simple observation may be considered, [5] especially if symptoms are minimal or absent. If symptoms are severe or persistent, peroral endoscopic myotomy (POEM ...

Heller myotomy is a surgical procedure [1] in which the muscles of the cardia (lower esophageal sphincter or LES) are cut, allowing food and liquids to pass to the stomach.It is used to treat achalasia, a disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to reach the stomach.
