Supports standardized observation, labs, and ultrasound in suspected appendicitis; leaves open whether gains are causal without randomized confirmation.
Do pre-operative investigations improve diagnostic accuracy in patients undergoing appendicectomy for suspected acute appendicitis?
A combination of active observation, standardized labs, and ultrasonography significantly improved diagnostic accuracy for acute appendicitis from 1986 to 1993 without increasing complications.
Styrud et al. (1999) studied this question.
