In a remarkable stride for minimally invasive gastrointestinal therapy, specialists at Apollo Speciality Hospitals, Teynampet have successfully excised a massive 15-cm laterally spreading adenoma from the sigmoid colon of an 80-year-old woman using Zoom-scope assisted Advanced Endoscopic Submucosal Dissection (ESD), marking the first such intervention in Tamil Nadu.

- Six-Hour Magnification-Guided Dissection Achieves Complete Tumor Removal Without Incision
- Scar-Free Intervention Prevents Cancer Risk, Enables Rapid Recovery for 80-Year-Old
- Milestone Reflects Expanding Frontiers of Therapeutic Endoscopy in Complex GI Care
The patient had presented with rectal bleeding and abdominal pain and was subsequently diagnosed with a large adenomatous growth with significant malignant potential. Considering the lesion’s size and anatomical complexity, standard treatment would ordinarily require open colorectal surgery involving bowel resection and prolonged recovery.
Defying these odds, the gastroenterology and advanced endoscopy team led by R Ravi undertook a demanding six-hour endoscopic procedure to achieve en-bloc removal of the entire tumor. The use of Zoom scope technology offered enhanced magnification and layered visualization, enabling precise identification of tumor margins and careful dissection along submucosal planes while preserving surrounding healthy tissue.
Histopathological evaluation later confirmed the lesion to be non-cancerous, effectively eliminating the threat of progression to colorectal cancer and reinforcing the preventive value of early, definitive intervention.
The minimally invasive approach translated into substantial patient benefits, including absence of abdominal incisions, minimal post-procedure pain, reduced complication risk, shorter hospital stay, and faster return to daily activities — advantages particularly critical for elderly individuals.
“Advanced Endoscopic Submucosal Dissection allows us to treat large and complex gastrointestinal tumors with remarkable precision while preserving the organ. The use of Zoom scope technology significantly enhanced our ability to visualize tissue layers and safely remove the lesion in a single piece. This case demonstrates how advanced endoscopy can prevent major surgery and significantly improve patient outcomes,” said Dr. R. Ravi, Clinical Lead, Gastroenterology, Liver Disease & Advanced Endoscopy, Apollo Speciality Hospitals, Teynampet.
Echoing the institution’s commitment to technology-led care delivery, Karan Puri, CEO, Apollo Speciality Hospitals, Teynampet and Apollo Proton Cancer Centre, said, ” Apollo Hospitals continues to invest in advanced technologies and specialized expertise that enable minimally invasive treatment options for complex conditions. This successful procedure reflects our commitment to innovation in gastrointestinal and cancer care, ensuring that patients receive safer treatments with faster recovery and better long-term outcomes.”
The successful management of this complex case underscores the transformative impact of advanced therapeutic endoscopy in contemporary gastrointestinal oncology. By leveraging precision imaging and refined endoscopic techniques, clinicians achieved complete tumor clearance while preserving organ function — offering elderly patients safer treatment pathways and renewed quality of life.
