Summary
Intraoperative endoscopy is crucial for detecting secondary upper digestive tract tumors in patients with obstructive hypopharyngeal carcinoma when preoperative evaluation is impossible. This method aids in diagnosing missed synchronous cancers.
Area of Science:
- Gastroenterology
- Oncology
- Surgical Oncology
Background:
- Hypopharyngeal carcinoma can present with obstructive masses, complicating preoperative diagnosis of secondary tumors.
- Early detection of synchronous upper digestive tract tumors is vital for effective cancer management.
Purpose of the Study:
- To establish the necessity of intraoperative endoscopy for diagnosing secondary primary tumors in the upper digestive tract.
- To evaluate the utility of intraoperative endoscopy in patients with obstructive hypopharyngeal carcinoma.
Main Methods:
- A retrospective analysis of 31 patients with hypopharyngeal squamous cell carcinoma operated between 1978 and 2004.
- Intraoperative endoscopy was performed via cervical esophageal incision in 7 patients (22.6%) with obstructive tumors precluding preoperative evaluation.
Main Results:
- Synchronous foregut carcinomas were identified in 3 patients (9.7%).
- One patient with an obstructive hypopharyngeal carcinoma had a T2 esophageal carcinoma detected solely by intraoperative endoscopy, missed by preoperative barium swallow and CT scan.
- Preoperative endoscopy detected synchronous carcinomas in the other two patients.
Conclusions:
- Intraoperative endoscopy is a valuable and necessary diagnostic tool for secondary primary tumors in the upper digestive tract.
- It serves as a selective screening test for patients with obstructive hypopharyngeal carcinoma, improving diagnostic yield.

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
