Laparoscopic predictive index value to determine disease distribution

	Score = 2	Score = 0
Peritoneal carcinomatosis	Unresectable massive peritoneal involvement + miliary pattern of distribution	Carcinomatosis involving a limited area surgically removable by peritonectomy
Diaphragmatic disease	Wide spread infiltrating carcinomatosis or confluent nodules to most part of the diaphragmatic surface	Isolated diaphragmatic disease
Mesenteric disease	Large infiltrating nodules or involvement of the root of the mesentery supposed by limited movements of various intestinal segments	Small nodules potentially treatable with argon beam coagulation
Omental disease	Tumor diffusion up to the large curvature of the stomach	Isolated omental disease
Bowel infiltration	Bowel resection assumed to be required or miliary carcinomatosis on the mesenteric junction
Stomach infiltration	Obvious neoplastic involvement of the gastric wall
Liver metastasis	Any surface lesions
