An endoscopic resecting apparatus views and resects a target tissue. The endoscopic resecting apparatus includes a sleeve, a compartmentalized tube, a visualizing device, an illuminating device, a first resecting mechanism, an irrigating apparatus, an aspirating apparatus, a gas insufflation apparatus, and an apparatus to instill a drug. The compartmentalized tube is disposed in the sleeve and has a first compartment of a first set of dimensions and a second compartment of a second set of dimensions larger than the first set of dimensions. A portion of the visualizing device is disposed in the first compartment so that it directly views the target tissue. A portion of the resecting mechanism is disposed in the second compartment so that it resects the target tissue. A portion of the irrigating apparatus is disposed in the first compartment. A portion of the aspirating apparatus is disposed in the second compartment so that it removes the resected target tissue. A portion of the gas insufflation apparatus and the apparatus to instill a drug are disposed in the sleeve. A transducer within the sleeve controls function of the gas insufflation apparatus. The drug instillation apparatus works in conjunction with the gas insufflation apparatus. The visualizing device, illuminating device, first resecting mechanism, irrigating apparatus, and aspirating apparatus are all contained within the same structure in order to function in an integrated and coordinated manner.
