Pancreatic Resection Tumor Surgery

A surgical procedure known as pancreatic resection involves removing all or a portion of the pancreas, usually as a result of tumours, either benign or malignant. The location, kind, and stage of the tumour determine how much surgery is required.

Typical Pancreatic Cancers That Need to Be Removed

1. The most prevalent malignant tumour, pancreatic adenocarcinoma, frequently occurs in the pancreatic head.
2. Neuroendocrine tumours (PNETs) can be either non-functional or functional, and they are less aggressive.
3. Cystic Neoplasms (like serous cystadenoma and IPMN; some need to be removed if they are precancerous).
4. Rarely, tumours from the kidney, colon, or melanoma can spread.

Types of Surgery for Pancreatic Resection

1. Whipple Procedure (duodenectomy of the pancreas)

• Removes the duodenum, gallbladder, head of the pancreas, a portion of the bile duct, and occasionally the stomach.
• Usage: For tumours in the periampullary or pancreatic head.
• Reconstruction: The pancreas, stomach, and bile duct are all joined to the intestine.

2. Pancreatomies distal

• The pancreatic body and tail (sometimes with spleen) are removed.
• For: Pancreatic tumours on the left side (e.g., PNETs, cysts).

3. Whole Pancreatectomy

• Removes the gallbladder, spleen, entire pancreas, and a portion of the stomach and intestines.
• For: Multifactorial diseases or large tumours.
• Insulin dependence (diabetes) and replacement of digestive enzymes are the results.

4. Laparoscopic/Robotic Minimally Invasive Resection

• Selected tumours (benign cysts, small PNETs) with this.
• Quicker recovery, though not appropriate for all types of cancer.

Symptoms Leading to Pancreatic Resection

Early Symptoms (Often Vague)

• Jaundice (yellow skin/eyes) – Due to bile duct obstruction (head tumors).
• Unexplained weight loss & loss of appetite.
• Abdominal pain (radiating to the back).
• New-onset diabetes (in some cases).

Advanced Symptoms

• Clay-colored stools & dark urine (biliary blockage).
• Nausea/vomiting (if tumor compresses stomach).
• Fatigue & weakness (from anemia or malnutrition).
