Which of the following is not done in carcinoma esophagus?

pH - metry/monitoring. ***pH - metry/monitoring*** - **pH metry/monitoring** is primarily used to diagnose **gastroesophageal reflux disease (GERD)**, which is not a direct diagnostic tool for esophageal carcinoma itself. - While GERD is a risk factor for **Barrett's esophagus** and subsequently adenocarcinoma of the esophagus, pH monitoring does not directly identify or stage the cancer. *CT chest* - **CT (Computed Tomography) chest** is routinely performed in esophageal carcinoma to assess the **local extent** of the tumor and identify potential **lymph node involvement** or **metastasis** to other organs. - It is crucial for **staging** the disease and guiding treatment decisions such as resectability. *PET scan* - A **PET (Positron Emission Tomography) scan** is highly useful for detecting **distant metastases** and identifying **occult disease** not visible on CT, especially in cases of suspected advanced esophageal carcinoma. - It helps in **accurate staging** and avoiding futile surgery in patients with metastatic disease. *Biopsy* - **Biopsy**, typically performed during endoscopy, is the **gold standard** for confirming the diagnosis of esophageal carcinoma by obtaining tissue for **histopathological examination**. - It identifies the cell type (e.g., adenocarcinoma, squamous cell carcinoma) and grade of the tumor, which is essential for treatment planning.
