OK...in French we say a 'B Flat'...your surgeon commited a B Flat meaning that he hit the wrong key and it made a really bad noise (a clunker or a big mistake)...Before throwing him out with the bathwater (to mix a few metaphores here) ask him why....
Sometimes (granted not that often) the rediculous things that some surgeons come up with can be related to real fears for your health and life...so before you give up completely on him please ask for clarification.
Too skinny? That may just be a problem...so ask if things can be done laproscopically...that would be a real life and time saver...What is the problem...blockages, strictures? Then yes, some surgeons can fix those without opening you up (most times...Do not forget that they never really know what they are going to find until they get in there).
My K pouch surgeon who is one of the last left standing of the original surgeons, never, ever considered laproscopic surgery on me (for good reason most of the time) but when geography and biology gave me no choice I went with a French expert who has done 6 or 7 procedures on me that way (after having had a stroll inside of me with open surgery while Dr C redid the whole k pouch +valve)...Dr C called that 'greatness'...working outside of the box...
So talk, ask questions, inquire and find out if there is not a Lap surgeon out there who can colaborate with your regular guy...
