Its in the autopsy, think he had cholecystectomy or something similar, (my laptop wont open links right now so running on my memory only so check it out)
It could have been appendix, right inguinal from what I recall, internal or external clips were still in situ, surgical wound, as far as I recall was described as recent, if indeed the clip sutures were external and still in situ it would suggest surgery had occurred within the previous week, 10 days max. Do check it tho' cos am runnin' on memory only
