Experimental transperitoneal laparoscopic pyloroplasty.
Interest in laparoscopic abdominal surgery continues to grow, which has persuaded a number of centers to pursue actively laparoscopic techniques that will allow surgeons to perform additional operative procedures in a less invasive manner. Peptic ulcer surgery, because of the morbidity associated with gastric surgery as well as the pain and discomfort associated with any major abdominal operation, has been largely replaced by pharmacologic therapy. As a result, patients are often advised to continue drug therapy indefinitely. This form of therapy, however, often only partially relieves the symptoms associated with peptic ulcer disease and leaves the patient at risk to develop life-threatening complications such as bleeding and perforation. Therefore, the rapid advances occurring in the field of laparoscopic surgery provide a fertile area for the development of simple, safe, and effective procedures to treat peptic ulcer disease in selected patients. A variety of different peptic ulcer operations have already been successfully performed under laparoscopic guidance. This report describes an experimental technique of transperitoneal stapled laparoscopic pyloroplasty using a modified end-to-end anastomotic stapling device (EEA Stapler; United States Surgical Corporation, Norwalk, CT, U.S.A.). The feasibility of this procedure was documented by detailed histologic evaluation of the pyloroplasty and revealed that the pyloric musculature had been excised, resulting in a true gastroduodenostomy. Pyloroplasty, coupled with either transabdominal or transthoracic vagotomy, could be a simple alternative to more extensive open abdominal surgery. This procedure represents one additional step in providing the practicing surgeon with the ability to perform a variety of different ulcer operations in a minimally invasive (laparoscopic) fashion.
