Gastric sleeve surgery is a widely performed restrictive bariatric procedure that aids in weight loss by permanently reducing the size of the stomach. Surgeons remove about 75% to 80% of the stomach, leaving behind a narrow, tube-like “sleeve.” This smaller capacity limits food intake and affects gut hormones that regulate hunger and fullness. Understanding the time logistics involved in the surgical process is a common concern for those considering the operation.
Duration of the Procedure Itself
The actual time the patient spends under general anesthesia while the surgeon is actively performing the sleeve gastrectomy is relatively brief. This laparoscopic procedure typically takes between 60 to 90 minutes from the initial incision to the final closure. This time frame represents the core surgical activity, which includes inflating the abdomen, dividing and stapling the stomach tissue, and removing the excised portion.
Advancements in minimally invasive techniques have helped keep this operating time short compared to older, open surgical methods. The laparoscopic approach contributes to a faster recovery and less pain compared to traditional, larger incisions. The surgical team focuses on precision and safety, ensuring the new stomach sleeve is properly formed and sealed before concluding the operation.
Total Time Commitment on Surgery Day
The total time commitment on the day of surgery extends far beyond the 60 to 90 minutes of the procedure itself. The timeline begins with the pre-operative preparation phase, which can take several hours. This involves hospital check-in, placement of intravenous lines, meeting with the nursing staff, and a final consultation with the anesthesiologist and surgeon.
Once in the operating room, the anesthesia induction phase begins, followed by the core surgical procedure. Afterward, the patient is moved to the Post-Anesthesia Care Unit (PACU) for immediate monitoring. This PACU stay typically lasts one to two hours while a specialized team monitors vital signs as the patient stabilizes. The entire process, from arrival at the hospital to transfer out of the PACU, frequently spans an estimated four to six hours.
Variables Affecting Operating Room Duration
The 60 to 90-minute surgical time is an average, and several specific patient and surgical factors can cause this duration to fluctuate. A primary variable is the patient’s Body Mass Index (BMI), as a higher BMI is often associated with increased technical difficulty. Greater visceral fat can make accessing the organs more challenging and may lengthen the time required for the procedure.
Previous Surgeries and Scar Tissue
The presence of scar tissue from previous abdominal surgeries, such as a C-section or gallbladder removal, can also increase the operating room time. Scar tissue may obscure the surgical field and require careful dissection, slowing the surgeon’s progress.
Surgeon Experience and Concurrent Procedures
The surgeon’s experience level and the efficiency of the surgical team are influential, as a well-coordinated team can perform the procedure more rapidly. Another element is the need for any concurrent procedures, such as a hiatal hernia repair, which will directly add to the overall duration of the operation.
