why are you having your sigmoid removed. I hope it is for real disease and not for a so called sigmoidocele that may be giving you issues with incomplete rectal emptying.
this is why i had mine and i went down a road worse than you can imagine. are you aware that they staple the ends of the colon together.
also any pelvic surgery can lead to small bowel adhesion obstruction. i got that.
if you do not have a disease or a twist of the sigmoid i would keep it if i were you.
if you have to have this done for disease get it done lapro with insuflow warmed humidified co2 insufflation gas as that does not dry your innards which can also give you small bowel adhesions.
not saying all this will happen to you even if you do have this surgery, but i ended up with a permanent ileostomy due to gut scarring< completely lost the use of my rectum due to a stricture at the join and almost died.
on review of the defecogram scan to assess why i wa having issue with incomplete rectal emptying it was not even a sigmoidocele in the first place! long story
then my ileostomy stoma that was great 4 years suddenly closed> a lap repair only lasted a month and now i just went thru a big major surgery to get a new stoma which so far i have to stay on a liquid diet to pass stuff tho the stoma is perfectly formed it cannot peristalse in and out. If you are having your sigmoid colon out for other than disease or twist think twice.
Good luck. Rosemary
