A medical method utilizes a tubular member. The method comprises inserting the tubular member through a patient's mouth into the patient's esophagus so that at least a portion of the tubular member is disposed in the patient's esophagus as a liner, and subsequently inserting flexible endoscopic surgical or diagnostic instruments through the patient's mouth and the tubular member in the esophagus into the patient's stomach. The tubular member is removed from the patient's esophagus after termination of the procedure. |
