The video demonstrates a direct drive endoscopic system for endoluminal and NOTES applications. The unit consists of a rail platform in a three channel, variably stiffening guide sheeth that accepts a pediatric endoscope and two 4 mm instruments. The drive handles glide on the rail platform transmitting hand motion to the instrument tip, imparting [...]

Other – Bilateral Tubal Ligation via Natural Orifice Transgastric Endoscopic Surgery

Anthony Kalloo, M.D., Johns Hopkins Medical Center

This is a demonstration of the experimental procedure, flexible transgastric fallopian tube ligation, using natural orifice transgastric endoscopic surgery or NOTES. This procedure has only performed in a laboratory setting under sterile conditions and has not been sanctioned for human use. First a hysterosalpingogram is performed demonstrating pat [...]

Other – Natural Orifice Transgastric Endoscopic Surgery – NOTES

Anthony Kalloo, M.D., Johns Hopkins Medical Center

This is a demonstration of the experimental procedure, flexible transgastric peritoneoscopy, now known as natural orifice transgastric endoscopic surgery or NOTES. This procedure has only performed in a laboratory setting and has not been sanctioned for human use. Here you can see an incision being made in a gastric wall using a standard needle kni [...]

Other – EUS with FNA of Malignant Celiac Lymph Node

Brenna C. Bounds, M.D., Harvard Medical School, Massachusetts General Hospital

The echoendoscope is in the stomach just beyond the GE junction. We can see a large, hypoechoic, homogenous structure representing a lymph node. This is a malignant celiac lymph node. The node is slightly lobulated. A fine needle aspiration is performed to document the presence of malignancy. [...]

Other – EUS Guided Celiac Plexus Neurolysis

Brenna C. Bounds, M.D., Harvard Medical School, Massachusetts General Hospital

We are looking at the celiac space from the stomach. The echoendoscope is just below the GEJ and we have placed a small needle through the posterior aspect of the gastric wall. The tip of the needle is positioned in the celiac space. The celiac artery on the left, the aorta below and the gastric wall above defines the celiac space. A celiac neu [...]

Ascites – Malignant Ascites EUS FNA

Brenna C. Bounds, M.D., Harvard Medical School, Massachusetts General Hospital

When ascites is seen in the context of malignancy, it is important to perform fine needle aspiration. FNA of ascites for cytology provides useful information, which is used for staging of malignancy. In this example, you see a fine needle passing through the gastric wall and aspirating a small pocket of fluid adjacent to the liver. [...]

Mediastinum – EUS of Pericardial Cyst

Brenna C. Bounds, M.D., Harvard Medical School, Massachusetts General Hospital

This patient was referred for evaluation of a large mediastinal mass identified on CT scan. Using endoscopic ultrasound we determine that this large, complex cystic structure, directly adjacent to the left atrium, is a pericardial cyst. [...]
