Reservations aside, the reader is invited to try the inching technique and make an individual assessment of its potential utility in his or her own situation. This might include the following steps:

  • After performing the inching technique, report to the prospective surgeon where you think the blockage might be with respect to anatomic landmarks

  • Make it clear that this is a tentative assessment (ie, done to the best of your ability but not to be taken as definite)

  • Ask the surgeon to tell you where the blockage actually seemed to be after surgery was performed

  • Keep track of your own findings compared with surgical findings, and draw your own conclusions about how accurate the inching method is in your own hands

Even if the inching technique does not yield the exact localization of the lesion, the attempt to use it may be helpful in and of itself insofar as it makes the clinician more conscious of the anatomy.
