Zenker's Diverticulum Endoscopic Treatment Confusion

Having treated many patients with Zenker's Diverticulum using the endoscopic approach, I've had many confused patients ask me how the diverticulum is treated if it is not removed.

For those unfamiliar with this disorder, click here for more information.

The basic concept of treating this rare disorder is that there is a common wall that divides the esophagus from the diverticulum pouch. This common wall is endoscopically divided such that the pouch now becomes the new back wall of the esophagus. So when the patient swallows, food/liquids can no longer get "trapped" causing symptoms.

Still confused? Here are some picture illustrations...

When endoscopically exposed, the pouch is denoted by the arrow.

When looking through the scope placed into the mouth down into the throat, there is a common wall that is between the pouch (blue arrow) and esophagus (green arrow).

Endoscopically, whether using a stapler or laser, this wall is divided down the middle. This picture shown below is when a stapler is used.

Here is the side view before and after common wall division:

After the procedure, any food/liquid substances that are swallowed can't be trapped in the pouch. Therefore, even though nothing is surgically removed, the patient's swallowing symptoms completely disappear.

Hopefully, this explanation helps clear up any confusion of what exactly happens!

New Webpage on Cauliflower Ear/Auricular Hematoma

Tis the time of year when auricular hematoma is common with high school wrestling. Just in the past 3 weeks, our office had to treat 4 ear hematomas in order to prevent cauliflower ear formation. Given how common it is based on the season, a new webpage has been created describing this condition and how it can be treated.

Needle Biopsy of Thyroid Masses Misidentifies 50% of Thyroid Cancers!

In the July 2009 issue of Archives of Surgery, surgeons at the University of Wisconsin published a paper entitled "Accuracy of Fine-Needle Aspiration Biopsy for Predicting Neoplasm or Carcinoma in Thyroid Nodules 4 cm or Larger". They found that fine needle aspiration biopsy (FNAB) in 26 of 52 FNAB reported as benign (50.0%) turned out to be either neoplastic (22) or malignant (4) on final pathologic analysis after thyroidectomy. Among patients with nondiagnostic FNAB results, the risk of malignant neoplasms was 27.3%.

Even for smaller thyroid masses, FNAB is still not 100% accurate. Why is that?

Well, one must keep in mind that the FNAB samples (or removes) only a tiny tiny tiny part of the thyroid mass (think of a needle going into an apple and trying to hit the worm in the middle). Should the needle sample a part of the thyroid cancer mass where no cancer is present, it will come back normal, even if it is truly cancer.

What does this mean for a patient with a thyroid mass?

1) The ONLY way to know 100% whether a patient has thyroid cancer or not is to remove the thyroid.
2) IF the FNAB shows thyroid cancer, total thyroidectomy is recommended.
3) IF the FNAB does not show thyroid cancer, thyroid cancer can STILL be there; it's just that the FNAB was just plain wrong. Thyroid lobectomy should still be considered.

Of course, one needs to talk with your local surgeon on what the next step is.

Just keep in mind that the FNAB is not 100% accurate!
