Gallbladder Polyps: When Is It Appropriate To Remove The Polyp While Preserving The Gallbladder

Gallbladder polyps come in various types, with cholesterol polyps often referred to as pseudo-polyps, and adenomatous polyps classified as true polyps. In standard medical practice, the general guideline for gallbladder removal has been when the polyp measures 10mm or larger. At this size, surgical removal is typically recommended due to an increased risk of malignancy. During the procedure, a rapid pathological examination is performed, and if cancerous changes are detected, a more extensive radical surgery for gallbladder cancer may follow.

However, recent studies and evolving medical perspectives suggest that polyps larger than 5mm may also carry some risk of becoming cancerous. Despite this, immediate gallbladder removal is generally not advised for smaller polyps because the likelihood of malignancy remains low, and the potential complications from surgery may outweigh the benefits. Instead, doctors often recommend regular monitoring through ultrasound scans to observe any changes in size or structure.

Once a gallbladder polyp reaches or exceeds 10mm in size, the risk of malignancy significantly increases. At this stage, surgical intervention becomes more critical, and the most effective treatment is cholecystectomy — the removal of the gallbladder. This is because the risk of leaving a potentially cancerous polyp untreated surpasses the risks associated with the surgery itself.

On the other hand, removing the gallbladder for a 5mm polyp may not always be necessary. An alternative approach gaining attention is the preservation of the gallbladder while removing only the polyp. This method, known as "polyp-only removal," allows the patient to retain their gallbladder function while eliminating the potential threat of a precancerous lesion.

For patients with polyps measuring over 5mm, the "gallbladder-preserving polyp removal" technique can be a viable and less invasive option. This procedure focuses on extracting the polyp while leaving the gallbladder intact, reducing the long-term digestive issues that can sometimes follow a full gallbladder removal.

In conclusion, while gallbladder removal remains the gold standard for polyps 10mm or larger, newer approaches are being explored for smaller polyps, especially those between 5mm and 10mm. Patients should work closely with their physicians to evaluate the size, growth rate, and characteristics of their polyps before deciding on the most appropriate treatment plan. Regular follow-ups and personalized medical advice are essential in managing gallbladder polyps effectively.
