Colonoscopic Polypectomy
Surgical field — Colonoscopic view. This is the Colonoscopic view of a sessile sigmoid colon adenomatous polyp. Ingection of Methylene blue stained saline beneath the tumor to rise the mucosa from sub mucosa to facilitate safe snare resection.

Endoscopic Submucosal Disection via working chanells of surgical endoscopes.
Gastric Ulcer
Endoscopic field—Flexible Endoscopic view of a big gastric ulcer near the Pylorus. Gastric ulcer [asterisk]; Pylorus(arrow).
Endoscopic view of Nissen fundoplication
The is the forward and reflexed view (Retrovision maneuver)in a patient demonstrating Nissen fundoplication for a sliding hiatal hernia. Black arrows show the wraps that are sutured together.
Huge Sliding Hiatal Hernia
Example of hudge sliding hiatal(esophageal) hernia on Endoscopy.This is the forward and reflexed view (Retrovision maneuver)in a patient demonstrating sliding hiatal hernia.
Radiograph of a PEG with J-tube extension
Radiograph showing a percutaneous endoscopic gastrostomy tube with a jejunal tube extension. Note the clip anchoring the distal end of the J tube. The patient also has a closed suction drain from a prior operation.
Rotating wheels on the headpiece of the endoscope
Rotating wheels on the headpiece of the endoscope control tip deflection. Instruments may be passed through an access port, which is kept capped when not in use (to prevent loss of insufflation and splashing of fluids).
Assuring Internal Reflection
A. Internal reflection is assured by cladding each fiber with a coating of high refractive index. Virtually all light is reflected back and forth within the fiber with little loss. B. The image produced by a fiberoptic endoscope is composed of a multitude
