How I do the Hassan technique:
I make an incision as deeply as conveniently possible, then place the Hassan S retractors to expose deeper. When I see the fascia, I make an incision in it. I then Poke through the peritoneum at the umbilicus with my finger (fastest technique and it is almost always weak just below umbilicus).
I then place my sutures on either side of the fascia, usually as half purse string sutures (like you would use if you placed a pursestring suture around a bowel end to use the EEA type automatic stapler).
I then place the blunt trocar and wind the sutures around the suture wings. The new versions, of course, have adjustable olives (wide sleeves that help maintain the pneumoperitoneum) so you can slide the trocar up and down inside the olive without resetting the sutures (the original versions could not be moved in and out without removing and reattaching the sutures, which was a nuisance.
I always bring the gallbladder out my subxiphoid port, because it is quickest.
I have only once injured the small bowel with the open technique in a reasonably muscular young man (but this was before I started using the above technique)---I made the skin and subcu incision, placed sutures in the fascia (old technique) and cut throught between the sutures and found I had caught a loop of small bowel in the fascial sutures. I pulled the loop of small bowel up through the umbilical port incision, put a few sutures in it and completed a lap appy. I tried to keep him NPO and in the hospital, but he insisted on eating that evening and wanted to go home the next day (I did of course tell him what had happened). He did fine. The message here is that you can repair these injuries easily.
