Argon plasma coagulation
Argon plasma coagulation (APC) is a non-contact monopolar electrosurgical technique that delivers current through ionized argon gas, used in the gastrointestinal tract and airways for hemostasis and ablation.
Cyanoacrylate injection
Cyanoacrylate injection is an endoscopic treatment in which medical-grade glue is injected into gastric varices to stop bleeding in portal hypertension, achieving hemostasis in about 90% of patients.
En bloc resection
En bloc resection is the removal of an entire tumor in a single piece so margins can be fully examined, chiefly done by endoscopic submucosal dissection.
Endoluminal vacuum therapy
Endoluminal vacuum therapy (EVT) is an endoscopic treatment in which an open-pore sponge applies continuous negative pressure to close gastrointestinal leaks and perforations, mainly anastomotic leaks after esophageal, gastric, or rectal surgery.
Endoscopic eradication therapy
Endoscopic eradication therapy (EET) treats Barrett's esophagus and related neoplasia by resecting visible dysplastic lesions and ablating remaining Barrett's mucosa, aiming to prevent esophageal adenocarcinoma.
Endoscopic hemostasis
Endoscopic hemostasis is the set of injection, thermal, mechanical, and topical techniques delivered through an endoscope to stop gastrointestinal bleeding, most often bleeding peptic ulcers.
Endoscopic mucosal resection
Endoscopic mucosal resection (EMR) is a minimally invasive endoscopic technique that removes flat or sessile gastrointestinal neoplasms by injecting fluid to lift the lesion, then cutting it off with a snare.
Endoscopic necrosectomy
Endoscopic necrosectomy is the endoscopic removal of infected or dead tissue from walled-off pancreatic necrosis through the gastric or duodenal wall, performed under endoscopic ultrasound guidance with sedation or anesthesia.
Endoscopic pyloromyotomy
Endoscopic pyloromyotomy, known as gastric peroral endoscopic myotomy (G-POEM), is a scarless endoscopic procedure that divides the pyloric muscle to treat refractory gastroparesis, first performed in 2013.
Endoscopic sleeve gastroplasty
Endoscopic sleeve gastroplasty is a minimally invasive bariatric procedure that reshapes the stomach into a narrow tube with endoscopic sutures, reducing its volume by about 70% to 80%.
Endoscopic vacuum therapy
Endoscopic vacuum therapy (EVT), also called endoluminal vacuum therapy or Endovac, is an endoscopic treatment that closes gastrointestinal leaks, perforations, and anastomotic dehiscence with a sponge under negative pressure.
Esophageal dilation
Esophageal dilation is an endoscopic procedure that widens a narrowed esophagus with bougies or balloons to relieve dysphagia from benign strictures, achalasia, or eosinophilic esophagitis.
Full-thickness resection
Full-thickness resection (FTR) is an endoscopic technique that removes a gastrointestinal lesion with all layers of the bowel or stomach wall, used for polyps and tumors that mucosal techniques cannot remove.
Functional lumen imaging probe
The functional lumen imaging probe (FLIP), marketed as EndoFLIP, is an endoscopic catheter that measures luminal distensibility during balloon distention, used to assess the esophagogastric junction and pylorus.
Hybrid argon plasma coagulation
Hybrid argon plasma coagulation (HAPC, also HybridAPC) is an endoscopic technique that combines submucosal saline injection with argon plasma coagulation through one catheter, mainly for Barrett's esophagus ablation.
LST trial
LST trial (NCT03498664), EMR-C vs EMR-S in colonic lateral spreading tumors: Italian randomized trial comparing cap-assisted with standard EMR for LSTs ≥30 mm; EMR-C gave lower residual disease (5.8% vs 31.4%) and fewer adverse events.
Mucosal ablation
Mucosal ablation is an endoscopic procedure that destroys abnormal mucosal tissue, most commonly precancerous Barrett's esophagus epithelium, using thermal methods like radiofrequency ablation and argon plasma coagulation, or nonthermal cryoablation.
Mucosectomy
Mucosectomy is an endoscopic procedure, known in the digestive tract as endoscopic mucosal resection (EMR), that removes a disk of mucosa to treat early cancers and precancerous lesions without surgery.
Natural orifice transluminal endoscopic surgery
Natural orifice transluminal endoscopic surgery (NOTES) is a minimally invasive technique operating on abdominal or thoracic organs through the mouth, anus, vagina, or bladder, with no abdominal-wall incision.
Per-oral endoscopic myotomy
Per-oral endoscopic myotomy (POEM) is an endoscopic procedure treating achalasia by dividing the lower esophageal sphincter muscle through a submucosal tunnel, with no skin incisions.
Peroral endoscopic myotomy
Peroral endoscopic myotomy (POEM) is an endoscopic operation that cuts the lower esophageal sphincter muscle to treat achalasia, performed through the mouth with no skin incision.
Polypectomy
Polypectomy is the endoscopic removal of polyps, most often from the colon during colonoscopy, using cold or hot snares; adenoma removal cuts colorectal cancer mortality by up to 50%.
RESECT-RGO trial
RESECT-RGO (NCT03357809), Endoscopic Resection in Gastro-Esophageal Reflux Disease, a French trial of endoscopic resection for GERD sponsored by Hospital St. Joseph, Marseille; suspended for lack of efficacy and poor tolerance, with no results posted.
SHORT-ESD trial
SHORT-ESD (NCT05347446) was a five-center US randomized trial comparing hybrid ESD, knife dissection plus snare resection, with conventional ESD for 20–50 mm nonpedunculated colorectal lesions: shorter procedure time (41.1 vs 54.3 min) but numerically lower en bloc and R0 rates.
Snare polypectomy
Snare polypectomy is an endoscopic procedure that removes gastrointestinal polyps with a wire loop tightened around the polyp, the standard method for colorectal polyps up to 19 mm.
Stricturotomy
Stricturotomy, or endoscopic stricturotomy, is an endoscopic technique that incises fibrotic gastrointestinal strictures with an electrosurgical knife to widen the lumen, used mainly for refractory Crohn's disease and benign anastomotic strictures.
Third space endoscopy
Third space endoscopy is a minimally invasive endoscopic technique that opens the submucosal layer as a working tunnel to reach lesions, best known for POEM, its myotomy for achalasia.
Transanal endoscopic microsurgery
Transanal endoscopic microsurgery (TEM) is a minimally invasive operation in which a rigid, sealed rectoscope is inserted through the anus to excise rectal tumors and close the defect, with no abdominal incision.
Transoral incisionless fundoplication
Transoral incisionless fundoplication (TIF) is an endoscopic antireflux procedure that rebuilds the gastroesophageal valve in chronic GERD patients using the EsophyX device, entirely through the mouth with no incisions.
Transoral outlet reduction
Transoral outlet reduction (TORe) is an outpatient endoscopic procedure, introduced in 2013, that narrows a dilated gastrojejunal anastomosis to treat weight regain or dumping syndrome after Roux-en-Y gastric bypass.
