Improved tumor staging by diagnostic laparoscopy.

This study was performed to assess the role of additional diagnostic laparoscopy in the preoperative staging of patients with adenocarcinoma of the esophagus, gastric cancer and pancreatic cancer prior to intended curative surgery. 89 patients with primary solid abdominal tumors were eligible for evaluation; of those 49 patients had a gastric cancer, 33 a pancreatic cancer and seven an adenocarcinoma of the esophagus. Patients without histologically proven metastases proceeded to laparotomy. Metastases were detectable laparoscopically in nine of 49 patients (18.4%) with gastric cancer (peritoneum n = 5, omentum n = 2, liver n = 2). Intraoperatively metastases were evident in further five cases (liver n = 3, peritoneum n = 2). In eleven of 33 patients (33%) with pancreatic cancer metastases were detected by laparoscopy (liver n = 6, peritoneum n = 2, liver and peritoneum n = 3) and in further four patients intraoperatively (liver n = 2, peritoneum n = 2). One of seven patients with an adenocarcinoma of the esophagus had liver metastases detected by laparoscopy. Intraoperatively no metastases were evident in those patients. Laparotomies were avoidable in 21 of the 89 patients (23.6%) who had a diagnostic laparoscopy prior to intended curative resection. Preoperative staging by additional diagnostic laparoscopy proved effective in patients with gastric and pancreatic cancer.
