Pretherapeutic assessment of resectability in patients with upper gastrointestinal tract cancer by using a combination of endoscopic ultrasonography (EUS) and laparoscopy.

An accurate pretherapeutic assessment of resectability in patients with upper gastrointestinal malignancies (UGIM) is mandatory in order to choose the optimal treatment strategy. Endoscopic ultrasonography (EUS) has significantly reduced the need for exploratory laparotomy in patients with UGIM, but the pretherapeutic evaluation in about 10% of the patients is incomplete due to certain limitations of the EUS. We prospectively evaluated the use and results of diagnostic laparoscopy in patients with UGIM selected for this procedure by EUS. In six patients with incomplete EUS, laparoscopy demonstrated nonresectability in five patients and a resectable tumor in one patient, and laparoscopy thus filled the informational gap in all cases. In addition, laparoscopy confirmed nonresectability in ten patients in whom EUS had suggested nonresectability. By employing the combinated use of EUS and laparoscopy it seems possible to avoid a great number of futile laparoscopies, and it should also reduce the need for explorative laparotomies. Larger prospective studies have been initiated and might be able to confirm this.
