Endoscopic Submucosal Dissection (ESD) in Okeechobee, FL

Endoscopic submucosal dissection, or ESD, is an advanced endoscopic technique that removes large, flat lesions and early cancers from the lining of the digestive tract in one piece. Using specialized knives passed through an endoscope, the endoscopist carefully dissects beneath the lining to free the entire lesion, rather than removing it in fragments. The result is a single, intact specimen — called an en bloc resection — that the pathologist can examine in full. ESD is performed by an advanced endoscopist and is used when the size, shape, or location of a lesion makes standard removal techniques unsuitable. ESD requires specialized training and equipment, and it is offered by only a small number of endoscopists.

ESD is used for large, flat lesions in the colon, stomach, and esophagus, and for early cancers that are limited to the inner lining of the digestive tract. When a cancer is confined to the innermost layer, removing it in one piece matters for staging: the pathologist can confirm that the entire lesion was removed and measure exactly how deeply it extends. That information determines whether endoscopic removal was curative or whether additional treatment, such as surgery, is needed. ESD can also remove large benign growths that would otherwise require a surgical operation. It is also considered when a lesion has recurred after a previous removal attempt, or when scarring from a prior procedure makes standard techniques difficult.

The key advantage of ESD over removing a lesion in pieces is precision. When a lesion is removed in one piece, the pathologist can examine its edges and depth reliably, which gives a clear answer about completeness. If a lesion is removed in fragments, the edges are harder to judge and it is more difficult to be certain that nothing was left behind. For early cancers, that certainty is essential, because it guides whether further treatment is required and how closely follow-up surveillance should be done. This precision is also why ESD is preferred for lesions where the distinction between a benign growth and an early cancer cannot be made until the whole specimen is examined.

ESD is performed at the hospital, where anesthesia and full support are available. Because ESD is a longer and more complex procedure than a routine endoscopy, it is done under anesthesia in the hospital setting, with the monitoring and resources that setting provides. Patients schedule a consultation at our office first, where Dr. Tarugu reviews your case, your prior endoscopy and pathology findings, and whether ESD is the right approach for your lesion. You will receive instructions about preparation, which is similar to the preparation for the underlying endoscopy, and about what to expect on the day of the procedure. After the procedure, the removed tissue goes to pathology, and follow-up surveillance is arranged to check the treated area and watch for recurrence. The length of the hospital stay and the recovery plan depend on the size and location of the lesion, and our office will confirm the specifics for your case.
