Early Precancerous Lesions Detected Through Endoscopic Screening
Article Table of Contents
Through the effective combination of highly skilled physicians, extensive clinical experience, and advanced medical technology, Hoan My Vinh Hospital has successfully identified numerous gastrointestinal lesions at very early stages. Early detection not only improves treatment outcomes but also reduces healthcare costs and alleviates the psychological burden on patients.
Detecting Disease Early Despite Vague Symptoms
Clinical practice at Hoan My Vinh Hospital has shown that many serious gastrointestinal conditions develop silently and can easily go unnoticed unless individuals proactively undergo health screening.
One such case involved patient D.T. (50 years old, Vinh Phu ward, Nghe An province), who visited the hospital due to persistent belching. During endoscopic examination, physicians identified abnormalities in the esophageal mucosa. To further characterize the lesion, the medical team utilized Narrow Band Imaging (NBI) technology available on the advanced Pentax Inspira 8020 endoscopy system.
As suspected, the examination revealed abnormal microvascular patterns within the esophageal mucosa, suggesting an early neoplastic lesion. Histopathological analysis subsequently confirmed high-grade dysplasia, a precancerous condition with a significant risk of progression to invasive esophageal cancer if left untreated.


In another case, Mr. C.X.Q. (40 years old, Thanh Vinh ward, Nghe An province) was found to have two large colorectal polyps measuring 2–3 cm with irregular surface morphology during a routine health check-up. These characteristics are considered high-risk features for malignant transformation. Notably, the patient had experienced no symptoms prior to the examination.
Dr. Nguyen Van Hoa, Specialist Level I and the physician who performed the endoscopic procedures, shared:
“In clinical practice, we frequently detect colorectal polyps and precancerous lesions during screening examinations before patients develop any clinical symptoms. Early detection combined with timely intervention plays a decisive role in controlling disease progression and minimizing the risk of serious complications in the future.”
According to Dr. Hoa, these cases demonstrate that the timing of diagnosis is not solely dependent on the presence of symptoms but largely on an individual’s willingness to participate in regular screening programs.
Gastrointestinal cancers often progress silently, presenting with nonspecific symptoms or no symptoms at all during the early stages. Gastrointestinal endoscopy remains the gold standard for early detection. When performed at the appropriate time, endoscopy can identify precancerous lesions before they develop into invasive cancer, significantly improving prognosis and treatment outcomes.
Based on this evidence, physicians recommend that individuals undergo regular gastrointestinal screening, particularly those aged 40 years and older or those with risk factors such as smoking, excessive alcohol consumption, chronic gastritis, Helicobacter pylori infection, or a family history of gastrointestinal cancers. Even in the absence of symptoms, routine screening remains an effective strategy for long-term health protection.
Strengthening Core Capabilities to Enhance Clinical Outcomes
In addition to medical expertise, advanced technology plays a critical role in improving diagnostic accuracy and treatment effectiveness.
At Hoan My Vinh Hospital, the Pentax EPK-i8020 endoscopy system incorporates advanced imaging technologies, including Narrow Band Imaging (NBI) and Optical Enhancement (OE), which provide enhanced visualization of mucosal structures and microvascular patterns. These capabilities enable physicians to detect subtle lesions in the esophagus, stomach, and colorectum at an early stage, even before symptoms appear.
Importantly, colorectal polyps can often be identified and removed during the same endoscopic procedure, reducing the risk of cancer development, minimizing the need for additional interventions, and lowering the likelihood of related complications. This approach also offers greater convenience, time savings, and cost efficiency for patients.
Advances in sedation-assisted endoscopy have further improved patient safety and comfort, making procedures smoother, faster, and significantly less uncomfortable. Patients recover more quickly after the procedure, with fewer adverse effects, helping to reduce anxiety associated with endoscopic examinations and encouraging greater participation in routine screening programs.

Alongside technological investments, Hoan My Vinh Hospital has implemented a standardized, closed-loop clinical workflow encompassing consultation, endoscopy, biopsy, pathology evaluation, and result reporting. This integrated approach shortens diagnostic turnaround times and enhances overall treatment effectiveness.
These achievements reflect the long-term strategic investment of Hoan My Medical Corporation in both human resources and medical technology, with the goal of continuously improving clinical quality and optimizing patient experience.
Advancing Toward International Healthcare Standards
In 2025, Hoan My Vinh Hospital welcomed an assessment team from ACHSI, one of the internationally recognized healthcare accreditation organizations, for a comprehensive evaluation of the hospital’s operations.
Successfully completing the assessment marked an important milestone in aligning hospital processes with internationally recognized standards for patient safety, service quality, continuous improvement, and patient-centered care. This achievement not only validates the hospital’s clinical capabilities but also reflects its systematic and professional development strategy.
Building on this foundation, the hospital continues to invest in modern medical equipment, strengthen workforce capabilities, and refine operational processes in accordance with international best practices. The integration of advanced technology, skilled healthcare professionals, and robust quality management is steadily helping the hospital achieve higher healthcare standards, delivering safe, effective, and patient-centered medical services while continuously enhancing the patient experience across the North Central region of Vietnam.
