Preoperative laparoscopy in management of patients with carcinoma of the esophagus and of the esophagogastric junction.

BACKGROUND AND

OBJECTIVES

Adequate preoperative staging of patients with esophageal and cardia carcinoma offers the potential for a rational choice of the therapy. The aim of this study was to assess the diagnostic value of laparoscopy compared to ultrasonography (US) and computed tomography (CT) in detecting intra-abdominal metastatic spread.

METHODS

Between November 1995 and December 1996, 36 patients with adenocarcinoma of the cardia and 14 patients with squamous cell carcinoma of the lower third of the esophagus were studied with CT scan and US, followed by laparoscopy performed at the same session of planned surgical resection. Mean operative time of laparoscopy was 20 minutes (range 15-55 min). There was no mortality nor morbidity related to the laparoscopic procedure.

RESULTS

Laparoscopy lead to a change of the therapeutic approach in five patients (10%): three patients with peritoneal carcinosis undetected at the imaging examinations, and one patient with advanced liver cirrhosis with signs of portal hypertension did not undergo resection; conversely, one patient with a liver hemangioma simulating a metastatic mass at CT/US underwent esophagogastric resection. Laparoscopy showed a higher sensitivity than US and CT in detecting peritoneal metastases (71% vs. 14% vs. 14%, respectively), macroscopic nodal metastases (78% vs. 11% vs. 55%), and liver metastases (86% vs. 71%).

CONCLUSIONS

Laparoscopy represents a safe and effective diagnostic procedure in the preoperative staging of esophageal and cardia carcinoma; it provides the potential to avoid unnecessary exploratory laparotomies and to select the most appropriate treatment.
