1. Introduction & Overview
Gastrointestinal (GI) oncology is systematically divided into Upper GI and Lower GI cancers, while Hepato-Pancreato-Biliary (HPB) cancers represent a dedicated specialized category.
Comprehensive surgical treatment options provided by Dr. Parveen Mendiratta include:
🩺 Upper GI Oncology (Esophagus, Stomach, Small Intestine & GIST)
- Esophageal Cancer Surgery: Transthoracic or transhiatal esophagectomy with precise gastric pull-up reconstructions.
- Stomach Cancer Surgery: Subtotal or total gastrectomy procedures with functional reconstruction of the digestive tract.
- Small Intestine & GIST Surgeries: Segmental resections and specialized clearances for small bowel tumors and Gastrointestinal Stromal Tumors (GIST).
🩺 Lower GI Oncology (Colon & Rectum)
- Colon Cancer Surgery: Precision resection of colon tumors with systematic clearance of regional lymph nodes.
- Rectal Cancer Surgery: High-precision sphincter-preserving surgeries (avoiding colostomy bags where possible).
The goal is accurate staging, negative margins, and optimal recovery outcomes.
2. Core Warning Signs
Early gastrointestinal warning signs can be subtle. Schedule a medical examination if you experience:
- Persistent difficulty swallowing (dysphagia) or frequent acid reflux.
- Unexplained weight loss and chronic abdominal discomfort or bloating.
- Persistent changes in bowel habits, black tarry stools, or rectal bleeding.
3. Diagnostic Protocol
Multi-dimensional screening ensures absolute staging precision:
- Upper GI Endoscopy & Colonoscopy: Direct visual examination and biopsy of suspect linings.
- High-Resolution Contrast CT Scans: Delineating exact tumor margins and assessing local vascular invasions.
- Endoscopic Ultrasound (EUS): Staging mucosal tumor depth with high precision.
4. Specialized Surgical Approaches
Dr. Parveen Mendiratta utilizes specialized surgical approaches tailored to the staging and location of the tumor. All of these surgical methods are performed using Open, Laparoscopic, and Robotic methods to ensure maximum precision and optimal healing:
🩺 Esophagectomies
- Access Routes: Performed via Cervical route, Transthoracic route, or Transhiatal (abdominal) route.
- Digestive Reconstruction: Re-establishing swallowing pathways using gastric and colonic pull-up techniques.
🩺 Gastrectomy
- Surgical Resections: Subtotal, total, and radical gastrectomies.
- Reconstruction: Meticulous reconstruction of the digestive tract to restore functional eating post-resection.
🩺 Colo-Rectal Surgeries
- Oncological Resections: Hemicolectomy and total colectomy.
- Sphincter-Preserving & Pelvic Clearance: Low anterior resection, anterior resection, and abdominoperineal resection (APR).
Note: Every esophagectomy, gastrectomy, and colorectal resection listed above is performed utilizing open, minimally invasive, laparoscopic or robotic assisted methods.
5. Post-Operative Clinical Recovery
Our post-surgical protocols prioritize rapid mobilization and specific nutritional progression plans. In close collaboration with specialized oncology nutritionists, we design progressive liquid-to-solid diet roadmaps to support optimal bowel recovery and physical healing.
