  • Liver cancer
  • Pancreatic cancer
  • Colon cancer
  • Anal cancer
  • Rectal cancer

Causes and risk factors for gastrointestinal cancer

The causes of many types of gastrointestinal cancer are unclear, but known risk factors are listed below, which vary depending on the type of cancer (please note that there are many other disease-specific risk factors):

  • Smoking
  • Excessive alcohol consumption
  • Increasing age
  • Diet high in animal fat
  • Diet high in salted, cured or poorly preserved foods
  • Chronic pancreatitis
  • Obesity

Symptoms of gastrointestinal cancer

  • Abdominal pain, tenderness or discomfort
  • Change in bowel habits, such as frequency, consistency or shape
  • Rectal bleeding or blood in stool
  • Bloating
  • Loss of appetite
  • Nausea or vomiting
  • Unintentional weight loss
  • Fatigue


  • Biliary bypass
  • Cholangioscopy and laser ablation therapy for intra-biliary lesions
  • Colonoscopy/polypectomy
  • Colorectal surgery
  • Endoscopic diagnostic and ablative techniques for Barrett's esophagus (including high-grade dysplasia) using endoscopic mucosal resection (EMR)
  • EMR for diagnosis and removal of precancerous lesions and early cancers
  • Endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (FNA) for diagnosis and staging of esophageal, gastric, pancreatic, mediastinal and rectal lesions and tumors
  • High-frequency mini-probes for staging early esophageal and gastric cancer
  • Liver resection
  • Medical oncology services
  • Minimally invasive placement of feeding tubes in the stomach or jejunum
  • Pancreatic surgery
  • Stents for esophageal, duodenal, biliary and colorectal obstructions
  • Surgeries of the esophagus, stomach and small intestine
  • Surgical management of endocrine tumors

We are offers a wide range of diagnostic and therapeutic services for patients with motility disorders, gastroesophageal reflux disease (GERD), inflammatory bowel diseases (ulcerative colitis and Crohn's disease) and pelvic diseases, such as female incontinence.

Endoscopic diagnosis and treatments for GERD and esophageal motility are successfully performed on an outpatient basis. These include:

  • 48-hour wireless pH capsule
  • Wireless largyngopharyngeal reflux monitor
  • High-definition esophageal impedence
  • Chromoendoscopy and endomicroscopy
  • Botulinum toxin for achalasia
  • Laparoscopic Heller myotomy
  • Endoscopic gastroplication
  • Laparoscopic fundoplication

Advanced laparoscopic therapy completes the entire spectrum of the latest modalities. Treatments for patients with pelvic diseases, such as female fecal incontinence, are a major focus.
