Diagnosis and therapy of ulcerative colitis--results of an evidence-based consensus conference of the German Society of Digestive and Metabolic Diseases

Abstract

This study was performed to assess the role of additional diagnostic laparoscopy in the preoperative staging of patients with gastric cancer and pancreatic cancer prior to intended curative surgery. Furthermore patients with ascites of unknown origin were evaluated. 127 patients with primary solid abdominal tumors were eligible for evaluation; of those 66 patients had a gastric cancer and 61 a pancreatic cancer. Patients without histologically proven metastases proceeded to laparotomy. Ascites of unknown origin was the indication for performing a diagnostic laparoscopy in 23 patients. Metastases were detectable laparoscopically in 13 of 66 patients (20%) with gastric cancer. Intraoperatively metastases were evident in further 7 cases. In 14 of 61 patients (23%) with pancreatic cancer metastases were detected by laparoscopy and in further 5 patients intraoperatively. A peritoneal carcinosis was diagnosed laparoscopically in 17 of 23 patients with ascites of unknown origin. Preoperative staging by additional diagnostic laparoscopy proved effective in patients with gastric- and pancreatic cancer.
