The Colorectal Center

SAMITIVEJ SUKHUMVIT

Colorectal Center

Precision Colonoscopy with AI-Enhanced Detection. 
Coordinated Cancer Care in One Dedicated Center.

When choosing where to undergo a colonoscopy, expertise matters.

Samitivej Sukhumvit Colorectal Center is Bangkok's dedicated center focused specifically on colorectal diseases — particularly colon cancer screening and treatment, serving patients across Thailand and throughout Southeast Asia.

We were established separately from the Liver & Digestive Institute to provide specialized care with a strong focus on precision in colonoscopy and colorectal disease treatment.

Recognized as one of Samitivej Sukhumvit Hospital’s Centers of Excellence, the Colorectal Center reflects structured standards, specialist expertise, and measurable clinical outcomes in colorectal care.

Why a Dedicated Colorectal Center?

Colorectal cancer often develops silently. Detecting early abnormalities depends on careful technique, clinical experience, and consistent quality standards.
Our center focuses specifically on:

  • Advanced colonoscopy screening
  • Early detection and removal of precancerous polyps
  • Comprehensive colorectal cancer treatment

Our doctors combine extensive colonoscopy experience with AI-supported high-definition imaging to enhance early lesion detection.

Through international collaboration with Sano Hospital—a private institution in Japan recognized for its advanced expertise in gastrointestinal (GI) endoscopy—our doctors integrate refined endoscopic techniques into practice while upholding ASGE (American Society for Gastrointestinal Endoscopy) quality benchmarks—standards we have continuously monitored and maintained for over 8 years.

From screening to surgery to oncology care, patients receive coordinated treatment within one integrated team.

One diagnosis. One treatment plan. One journey.

Clinical Outcome Highlights

Measured Quality. Transparent Results.

We monitor colonoscopy performance in alignment with ASGE (American Society for Gastrointestinal Endoscopy) quality indicators, using these benchmarks to guide continuous quality improvement and transparent outcome reporting.

Colonoscopy Quality Indicators (ASGE Benchmarks for Reference)

  • Medically indicated procedures only: 100% | ASGE 80%
  • Adequate bowel preparation rate: 90% | ASGE 85%
  • Complete examination (Cecal Intubation Rate): 100% | ASGE 95%
  • Withdrawal time ≥ 6 minutes: 100% | ASGE 100%
  • Complete medical documentation: 100% | ASGE 95%

Outcome Indicators

  • Perforation rate: 0% | ASGE 0.1%
  • Post-polypectomy bleeding: 0.1% | ASGE 1%
  • Adenoma Detection Rate (ADR):*
    • Age 50+: 45% | ASGE 35%
    • All ages: 40% | ASGE 35%

Based on 27,687 cases at Samitivej Hospital (2017–2025).
*ADR is recognized as a key quality indicator in colorectal cancer prevention.

Colonoscopy: Where Precision Makes the Difference
A colonoscopy is not just a procedure—it is a skill.

  1. Clinical Expertise Refined by Experience
    With 27,687 colonoscopy procedures performed between 2017–2025, our gastroenterologists have developed substantial clinical experience in detecting both obvious and subtle lesions, further strengthened through ongoing clinical collaboration with SANO Hospital in Japan.
  2. AI-Supported Detection Precision
    We integrate AI-assisted imaging, including EndoBRAIN-EYE, during colonoscopy. Used alongside our gastroenterologists’ expertise and refined endoscopic techniques, AI enhances real-time lesion recognition—supporting greater precision in detecting small or subtle abnormalities.
  3. Strict Bowel Preparation Standards
    Clear visualization is essential for accurate detection. We follow standardized bowel preparation protocols to ensure optimal mucosal visibility. If preparation is inadequate, the procedure may be rescheduled to maintain diagnostic quality.
  4. Quality Monitored by International Benchmarks
    Our colonoscopy performance is continuously monitored according to ASGE (American Society for Gastrointestinal Endoscopy) quality indicators—ensuring consistency, completeness, and measurable standards of care.

Alongside diagnostic precision, patient safety is supported by anesthesiologist-supervised sedation. Board-certified anesthesiologists provide continuous monitoring to ensure stable vital signs throughout the procedure.

Conditions We Treat:

  • Hemorrhoids
  • Colon cancer
  • Colon polyps
  • Anal abscess
  • Anal fissure
  • Anal fistula/fistula-in-ano (LIFTS)
  • Chronic inflammatory bowel disease, Crohn's disease
  • Rectal prolapse
  • Rectal bleeding
  • Constipation, incomplete or difficult evacuation of the bowels
  • Fecal incontinence
  • Anal pain or discomfort
  • Anal growths or polyps
