Apollo Hospitals successfully removes colon tumor using advanced technology

Apollo Speciality Hospitals, Teynampet, successfully performed a complex minimally invasive endoscopic procedure to remove a large 15 cm laterally spreading adenoma, a type of Polyp in the sigmoid colon of an 80-year-old woman using Advanced Endoscopic Submucosal Dissection. It is supported by Zoom scope technology, marking the first time this advanced technology has been used for such a, a type of procedure in Tamil Nadu.

The patient had presented with rectal bleeding and abdominal pain and was diagnosed with a large laterally spreading adenoma in the sigmoid colon, which carried a high risk of malignant transformation if left untreated. Given the size and location of the tumor, the case required advanced endoscopic expertise and precision.

The medical team successfully performed an en-bloc removal of the entire 15 cm lesion using Endoscopic Submucosal Dissection, a highly specialized therapeutic endoscopy technique that enables removal of complex gastrointestinal tumors without the need for open abdominal surgery. The procedure lasted approximately six hours and was supported by Zoom scope technology, which provided enhanced magnification and detailed visualization of tissue layers. This allowed accurate identification of tumor margins and precise dissection of submucosal planes, ensuring complete removal while preserving the organ.

By opting for this advanced endoscopic approach, the team avoided major colorectal surgery that would typically involve bowel resection and prolonged recovery. Histopathology results confirmed that the tumor was non-cancerous, effectively preventing potential progression to colorectal cancer. The minimally invasive nature of the procedure ensured significant benefits for the patient, including absence of abdominal incisions, reduced post-procedure pain, faster recovery, shorter hospital stay, and a lower risk of complications compared to conventional open surgery. The success of this case underscores the expanding role of advanced therapeutic endoscopy in managing large and complex gastrointestinal tumors, particularly in elderly patients who may not be ideal candidates for major surgery.

Dr. R. Ravi, Clinical Lead, Gastroenterology, Liver Disease & Advanced Endoscopy, Apollo Speciality Hospitals, Teynampet said, “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.”

Mr. Karan Puri, CEO, Apollo Speciality Hospitals, Teynampet and Apollo Proton Cancer Centre, Taramani 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 outcome of this complex case highlights how advanced endoscopic innovations are transforming the management of gastrointestinal tumors. By leveraging Endoscopic Submucosal Dissection supported by Zoom scope technology, the medical team was able to achieve complete tumor removal while preserving the patient’s colon and avoiding major surgery, offering safer treatment and improved quality of life.
