Hi Kathleen, I don't want to overstep your word, however, they do BOTH "partial" AND "total" colectomies.For colonic inertia patients - most have their ENTIRE colon removed - only a few have a couple of feet removed, however, they later end up having to have the rest of the colon removed (within a year or two).Also, each surgeon has his/her own preference of performing the TOTAL COLECTOMY "open" or "laparoscopic" - surgeons who do "laparoscopic" MUST undergo a certain amount of hours of study and assistance in the actual procedure before they're board certified to practice "laparoscopic"You are correct in saying this type of surgery does nothing for pelvic floor problems - that's a totally different issue.Also, the "partial" colectomy is more for people that have severe diverticular problems and the "total" colectomy is more for Colonic Inertia.
