GI Oncosurgery

Introduction to GI Oncosurgery

Gastrointestinal Oncosurgery is a highly specialized surgical branch that focuses on diagnosing and surgically treating cancers within the digestive system. These cancers include malignancies of the esophagus, stomach, small intestine, colon, rectum, liver, pancreas, gallbladder, and bile ducts. GI cancers can be complex due to their location, vascularity, and tendency for late detection.

As a Consultant Surgical Gastroenterologist at Apollo Speciality Hospitals, Nellore, Dr. Nitesh Pagadala brings in-depth expertise in advanced cancer surgeries of the gastrointestinal tract, ensuring oncological clearance while preserving function and quality of life.

Why GI Oncosurgery Requires a Specialist

GI cancer surgeries are not just about tumor removal—they demand:

• Precise staging and localization

• Vascular control

• Multidisciplinary approach (oncologists, radiologists, nutritionists)

• Organ preservation and reconstruction

• Expertise in open, laparoscopic, and robotic-assisted techniques

Dr. Nitesh’s training in Surgical Gastroenterology (MCh) from SVIMS and fellowship in HepatoBiliary and Pancreatic Surgery at JIPMER makes him exceptionally qualified to handle these complexities.

Types of GI Cancers Treated Surgically

Dr. Nitesh offers surgical treatment for a wide range of gastrointestinal malignancies:

1. Esophageal Cancer

• Symptoms: Difficulty swallowing, weight loss, chest pain

• Surgeries: Transthoracic esophagectomy, minimally invasive esophagectomy (MIE)

2. Stomach (Gastric) Cancer

• Procedures: Total or subtotal gastrectomy, D2 lymphadenectomy

• Laparoscopic gastrectomies offered for early-stage cancers

3. Colorectal Cancer

• Surgeries: Right hemicolectomy, sigmoid colectomy, low anterior resection (LAR), abdominoperineal resection (APR)

• Expertise in sphincter-saving procedures wherever possible

4. Liver Tumors (Hepatocellular carcinoma, Cholangiocarcinoma)

• Resections: Left or right hepatectomy, segmentectomy

• Integrated pre-op imaging, intraoperative ultrasound for precision

5. Pancreatic Cancer

• Surgeries Offered: Whipple’s procedure (Pancreaticoduodenectomy), distal pancreatectomy

• One of the most complex GI oncological surgeries, performed with utmost expertise

6. Gallbladder and Bile Duct Cancers

• Procedures: Extended cholecystectomy, bile duct resection with hepaticojejunostomy

7. Small Bowel and Gastrointestinal Stromal Tumors (GIST)

• Segmental resections with negative margins and laparoscopic techniques

Surgical Techniques Employed

Depending on the tumor type, stage, and patient fitness, Dr. Nitesh uses:

• Open Surgical Techniques: For large or advanced tumors requiring wide exposure

• Advanced Laparoscopy: Minimally invasive, faster recovery, lesser pain

• Multivisceral Resections: When the tumor involves adjacent organs

• Neoadjuvant/Adjuvant Planning: Coordination with oncology teams for chemotherapy or radiotherapy before/after surgery

Pre-operative Evaluation

• Endoscopy, colonoscopy

• Contrast-enhanced CT (CECT), MRI, PET-CT

• Tumor markers (CEA, CA19.9, AFP)

• Biopsy and histopathological confirmation

• Staging laparoscopy in some cases

Postoperative Recovery and Rehabilitation

• ICU monitoring for complex surgeries

• Nutritional support with dietitians

• Physiotherapy and early mobilization

• Stoma care (for rectal cancers, if required)

• Psychological support and long-term follow-up

FAQs

Q: Are all GI cancers operable?
A: Not all. Operability depends on the stage, location, and metastasis. However, some non-resectable tumors can be managed palliatively or converted to operable after neoadjuvant therapy.

Q: Is chemotherapy mandatory after GI surgery?
A: It depends on the pathology report (tumor grade, margins, lymph nodes). Some cases require adjuvant chemotherapy or radiotherapy.

Q: Can laparoscopic surgery be used for cancer?
A: Yes, especially in early stages. Dr. Nitesh performs advanced laparoscopic resections for selected GI cancers.
