Gastric sleeve (sleeve gastrectomy) is a bariatric surgery procedure that takes about 1-1.5 hours on average when performed with a laparoscopic (keyhole) technique. However, the "duration" patients wonder about often covers not just the time on the operating table, but the entire process, including preparation, anesthesia, hospital stay, and recovery. In this article, we explain each of these timeframes step by step.
How long does the surgery itself take?
The surgical part of a laparoscopic gastric sleeve procedure is usually completed within 1-1.5 hours. This time can be shorter or longer depending on the patient's anatomy, previous abdominal surgeries, and overall health. When anesthesia preparation and the recovery period are added, the total time spent in the operating room is somewhat longer.
Factors that affect the surgery duration
| Factor | Effect on duration |
|---|---|
| Patient's anatomy | Intra-abdominal structure and level of fat can affect the duration. |
| Previous abdominal surgeries | Adhesions may extend the procedure somewhat. |
| Additional health conditions | Anesthesia and surgical planning are adjusted accordingly. |
| Experience of the surgical team | Process planning and flow are related to experience. |
How long does the preparation before surgery take?
Before the day of surgery, there is a preparation process that includes blood tests, endoscopy, imaging, and any necessary consultations. These assessments are usually completed in the days before surgery and are essential for a safe operation.
How long is the hospital stay?
After gastric sleeve surgery, patients are generally kept under observation in the hospital for 2-3 days. During this time, fluid intake, movement, and overall condition are monitored. The time of discharge is determined by the physician based on how quickly the patient recovers.
How long does recovery and the return to daily life take?
- First days: a mostly liquid diet and gradual movement.
- First weeks: a gradual transition from puréed to solid foods, with dietitian follow-up. For details, you can see our nutrition guide.
- Return to daily/work life: this varies with how physically demanding the job is and is planned on your physician's advice.
Recovery time varies from person to person; it is important to wait for your physician's recommendations before returning to strenuous physical activity.
A typical timeline on the day of surgery
- Hospital admission and final preparations.
- General anesthesia and the laparoscopic operation (about 1-1.5 hours).
- Recovery room, followed by transfer to the ward/room.
- 2-3 days of observation and discharge.
