Description of intervention(s) / exposure
Other interventions - Enhanced Recovery After Surgey for Sleeve Gastrectomy

Active Comparator: ERAS - The perioperative management of the patients in this arm will be according to a fast-track protocol designed by the investigators. The preoperative component of this program is the same as routine practice. Intraoperative and postoperative components which are different to routine practice are as described in the intervention section. This protocol is based on current literature regarding Enhanced Recovery After Surgery (ERAS).

No Intervention: non ERAS - The perioperative management of patients in this arm will be according to routine practice currently implemented at our institution.

Brief summary
The investigators wish to standardise and optimise perioperative care for consecutive
patients undergoing laparoscopic sleeve gastrectomy for weight loss. The investigators will
compare patients under a standardised perioperative care program to patients who undergo
routine perioperative in our hospital and determine whether patients who had optimised
perioperative care went home earlier and had fewer complications.
