Sydney's most trusted laparoscopic sleeve gastrectomy — 1,000+ successful procedures by Dr Oliver Florica FRACS.
Gastric sleeve surgery (sleeve gastrectomy) is a minimally invasive procedure that permanently reduces the size of the stomach by approximately 75–80%.
By reshaping the stomach into a narrow tube or "sleeve", the procedure reduces the amount you can eat at one time and significantly lowers levels of the hunger hormone ghrelin — leading to reduced appetite and significant, sustained weight loss.
All procedures are performed laparoscopically (keyhole surgery), meaning smaller incisions, less pain, and faster recovery compared to traditional open surgery.
Procedure time: 60–90 minutes | Hospital stay: 2–3 days | Return to work: 2–3 weeks
Most patients lose 60–70% of their excess body weight within 12–18 months, with many achieving a healthy BMI long-term.
Gastric sleeve often leads to remission or significant improvement of type 2 diabetes, hypertension, sleep apnoea, and joint pain.
No rerouting of the intestine — the sleeve is a single, straightforward procedure with a favourable risk profile and excellent outcomes.
Laparoscopic technique means most patients are walking the day after surgery and returning to normal activities within 2–3 weeks.
Removal of the fundus (where most ghrelin is produced) significantly reduces appetite, making it easier to maintain a healthy diet.
Medicare rebates are available for gastric sleeve surgery when performed by a qualified surgeon like Dr Florica FRACS. Private health insurance may cover hospital fees.
Gastric sleeve surgery is generally considered for adults who meet the following criteria:
The best way to determine if you're a suitable candidate is through a comprehensive consultation with Dr Keeley and Dr Florica. Every patient's situation is unique.
You will be fully asleep throughout the procedure.
Small incisions are made in the abdomen and a camera (laparoscope) is inserted.
Approximately 75–80% of the stomach is stapled and removed, leaving a sleeve-shaped pouch.
Incisions are closed. You'll be monitored in hospital for 2–3 nights before discharge.
