3. Tolerance to drugs
There are cases where for some reason the patient is used to take strong painkillers (narcotics) After Bariatric Surgery, or sedatives (benzodiazepines, etc.). If the Bariatric Surgery patient has taken them for a long period of time there is a chance that he/she has developed some tolerance, so the usual dose for postoperative pain control will not be enough for them.However this does not mean that pain cannot be controlled in these cases, but will require higher doses. Hence the importance that your surgeon gets to know in detail your particular case and that the patient provides him/her with information of the medications (or drugs) you take regularly.
4. Excessive manipulation during surgery
One of the reasons that we ask the Bariatric Surgery patient to undergo a preoperative diet before Bariatric Surgery, when the case warrants it, is to let the technique used in surgery become as “simple” as possible.Achieving certain preoperative weight loss makes it easier for your surgeon and this will translate in much less manipulation of your internal organs, more specifically your liver, stomach and its surroundings, along with less need of manipulation of the incisions on the abdominal wall.
5. The lack of experience of the surgeon in this procedure
We dare to make the observation that if Bariatric Surgery is being offered via conventional approach, meaning open surgery with a large incision from the sternum to near the navel, consider to look for more options because the only reason to start a gastric sleeve with the conventional technique would be because of lack the surgeon’s experience with the laparoscopic technique, which is fully established and indeed this is how the gastric sleeve was “born”, as a pure laparoscopic procedure.
