Current treatment options for esophageal diseases

Area of Science:

• Gastroenterology and Esophageal Surgery

Background:

• Esophageal diseases present significant therapeutic challenges, with refractory gastroesophageal reflux disease (GERD) and Barrett's esophagus requiring novel treatment strategies.
• Current management for distal esophageal spasm relies on pharmacologic and endoscopic interventions.
• Barrett's esophagus management, including proton pump inhibitors or antireflux surgery, is crucial due to its association with neoplastic progression.

Purpose of the Study:

• To review recent advancements in pharmacologic, endoscopic, and surgical treatments for various esophageal diseases.
• To highlight emerging therapeutic options for refractory GERD.
• To discuss the evolving standards of care for esophageal cancers, including early adenocarcinoma and squamous cell carcinoma.

Main Methods:

• Review of current literature on pharmacologic, endoscopic, and surgical interventions for esophageal diseases.
• Analysis of meta-analyses regarding treatment efficacy, such as for Barrett's esophagus.
• Description of novel techniques like endoscopic resection, radiofrequency ablation, endoscopic submucosal dissection, and robot-assisted esophagectomy.

Main Results:

• New therapeutic options show promise for refractory GERD.
• Proton pump inhibitors or antireflux surgery significantly reduce neoplastic progression risk in Barrett's esophagus.
• Endoscopic resection with radiofrequency ablation is standard for early esophageal adenocarcinoma; endoscopic submucosal dissection is preferred for mucosal squamous cancer.
• Robot-assisted esophagectomy offers a minimally invasive approach for upper esophageal cancer.
• Induction chemoradiotherapy is standard for advanced squamous cell carcinoma; neoadjuvant therapy for adenocarcinoma is debated.
• A system for perioperative complication assessment in esophagectomy has been developed.

Conclusions:

• Significant progress has been made in treating esophageal diseases through pharmacologic, endoscopic, and surgical innovations.
• Minimally invasive endoscopic and surgical techniques are increasingly important for managing esophageal cancers.
• Further research is needed to clarify the role of neoadjuvant therapy for esophageal adenocarcinoma and to identify predictors of perioperative complications.
