Factors influencing change of preoperative treatment intent in a gastrointestinal cancer practice

Table 1 Utilization for standard diagnostic procedures, by intraabdominal organ site

Organ site	CT	MRI	EUS	Laparoscopy
Esophagus (n = 10)	100	0	40	60
Stomach (n = 72)	93	10	28	56
Small bowel (n = 18)	83	6	6	33
Colon (n = 17)	88	12	0	6
Rectum (n = 19)	95	21	44	11
Liver (n = 84)	83	83	2	15
Bile ducts (n = 47)	96	43	13	53
Pancreas (n = 125)	95	32	40	76
Retroperitoneum (n = 12)	100	67	8	17
Soft tissues (n = 10)	80	40	10	10

Numbers reflect % (rounded) of patients within the disease group who had undergone the diagnostic test. The patient numbers within diagnostic sites do not add up to 406, since extraabdominal and hematologic diagnoses were excluded, and 75 patients carried combined diagnoses of different organ sites.
