Sometimes insertion is difficult due to kinking, resistance, bulging and not advancing in the right spot requiring re introduction, help from a colleague, or change to the thick silicone type. When tube is changed during insertion to the silicone type the method insertion is compared with the previous approach.~A note is made of the problem encountered, how long it took to place it correctly ( time from insertion till first staple), what was done to solve the problem, if a new identical tube was used or another and what type was used. If another tube how log did it take to get first stapler done.~some demographic and procedure information is recorded: gender, age, BMI, procedure planned, first bariatric procedure or second after ...
