The median length of stay following a SG was 2 [2,3], this was
unaffected by: operation day (P=0.245) Table 1 , ASA grade
(p=0.143), a pre-operative diagnosis of diabetes (p=0.805) and BMI
(P=0.345) Table 2 . There was nil peri-operative mortality.
The median length of stay following a RNY was 2[2,3], this was
unaffected by: ASA grade (p=0.952) or the patient being diabetic
(P=0.366). However, day of the week significantly increased length of
stay (Table 3 ) with patients who underwent a RNY on Friday
staying on average 1 day more compared (p=0.002). Patient’s with a BMI
>60 who underwent a RNY stayed an average of 2 days more
than patients with a BMI between 30 and 59.9 (P=0.008) (Table
4 ).
Readmission rates (30 and 60-day) were similar between the two
operations. 30-day readmission rates were 6 SG patients and 7 RNY
patients. 60-day readmission rates were 6 and 9 respectively.
