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.
