Abdominal Onco Surgery is a specialized branch of surgery focused on the diagnosis and surgical treatment of cancers affecting the abdominal organs. These may include cancers of the liver, stomach, gallbladder, pancreas, bile ducts, colon, rectum, small intestine, and appendix. Early diagnosis and timely surgical intervention play a crucial role in improving survival and enhancing the quality of life for patients. Many abdominal cancers develop silently and may not cause symptoms in the early stages. As the disease progresses, patients may experience persistent abdominal pain, unexplained weight loss, loss of appetite, jaundice, changes in bowel habits, blood in the stool, abdominal swelling, nausea, vomiting, or fatigue. These warning signs should never be ignored and require prompt evaluation by a specialist. Diagnosis involves a detailed clinical assessment along with blood tests, tumor markers, ultrasound, CT scan, MRI, PET-CT (when indicated), endoscopy, colonoscopy, and biopsy to confirm the diagnosis and determine the stage of cancer. Accurate staging helps in planning the most effective treatment strategy. Surgery remains one of the most effective treatments for many abdominal cancers. Depending on the type and stage of the disease, procedures may include tumor removal, liver resection, gastrectomy, pancreatic surgery, colectomy, rectal cancer surgery, or gallbladder and bile duct surgery. In many cases, surgery is combined with chemotherapy, targeted therapy, immunotherapy, or radiotherapy as part of a multidisciplinary treatment approach to achieve the best possible outcomes.
