Complicated Sleeve Gastrectomy in Turkey
Specialist gastric sleeve for patients with complex medical histories or previous abdominal procedures, from £3,045.
A complicated sleeve gastrectomy is a gastric sleeve procedure performed on patients whose anatomy, medical history, or previous surgical procedures make the standard approach more technically demanding. This might include patients with significant internal scar tissue (adhesions) from prior abdominal surgery, those with a very high BMI, or patients with anatomical variations that require additional surgical expertise.
The outcome is the same as a standard gastric sleeve, approximately 80% of the stomach is removed, leaving a narrow sleeve that reduces both the amount you can eat and the hormones that drive hunger. The difference is in the complexity of the procedure itself, which requires more time, greater surgical skill, and a longer hospital stay for monitoring.
If you have been told by other clinics that your case is "too complex" or that you are not suitable for a gastric sleeve, it is worth seeking a second opinion. The surgical teams in The Health Store Turkey's network have extensive experience with complicated cases and regularly operate on patients that other providers have turned away.
Your all-inclusive package covers the procedure in a government-licensed hospital, 4 nights of hospital care, 5-star hotel accommodation, private airport transfers, a personal translator, and 12 months of dedicated aftercare. From £3,000, fully inclusive.
What Is Complicated Sleeve Gastrectomy?
What Makes a Sleeve "Complicated"?
A gastric sleeve is classified as complicated when there are factors that increase the technical difficulty of the procedure. These include:
Previous abdominal surgery: If you have had prior operations (such as a previous bariatric procedure, gallbladder removal, hernia repair, or caesarean section), internal scar tissue (adhesions) may have formed. These adhesions can make it harder for the surgeon to access the stomach and require careful dissection before the sleeve can be created.
Very high BMI: Patients with a BMI above 50-55 present additional challenges, including a larger, fattier liver that can obscure the surgical field, and thicker abdominal walls that make laparoscopic access more difficult.
Anatomical variations: Some patients have unusual stomach shapes, enlarged spleens, or other anatomical features that require the surgeon to adapt their approach.
Failed previous bariatric procedure: Patients converting from a gastric band or revising a previous sleeve may have altered anatomy that adds complexity.
The Procedure Itself
The procedure follows the same principles as a standard gastric sleeve, performed laparoscopically under general anaesthesia, approximately 80% of the stomach is removed using a surgical stapler. However, a complicated sleeve typically takes longer (60-90 minutes compared to 45-60 minutes for a standard sleeve) and may require additional steps such as adhesion removal, liver retraction, or modified port placement.
The weight loss results are equivalent to a standard sleeve. Most patients lose 60-70% of their excess body weight within 12-18 months.
Am I Suitable?
A complicated sleeve gastrectomy may be appropriate if:
- Your BMI is 30 or above and you have factors that make a standard sleeve more technically challenging
- You have had previous abdominal surgery that may have caused internal adhesions
- You have a very high BMI (50+) that requires specialist surgical planning
- You have been turned away by other providers due to the complexity of your case
- You are committed to long-term lifestyle changes after the procedure
You may not be suitable if you have active infections, unmanaged heart or lung conditions that make prolonged general anaesthesia unsafe, or if your medical team determines that an alternative procedure would be safer for your specific situation.
Your free consultation includes a thorough review of your surgical history, current health, and any imaging or records from previous procedures. Your surgical team will assess whether a complicated sleeve is safe and appropriate, or whether a different approach might be recommended.
What Happens During the Procedure?
Before Your Procedure
Your consultation is more detailed than for a standard sleeve. Your patient coordinator collects your full surgical history, previous operative reports (if available), and any recent imaging. This information helps your surgical team plan the safest approach for your individual anatomy.
You receive the same preparation guidance as for a standard sleeve, including a 2-week liver-shrinking diet that is particularly important for complicated cases, as reducing liver size gives your surgeon better access.
On the Day
Pre-operative checks include comprehensive blood tests, imaging, and consultations with your surgeon and anaesthetist. Your surgeon discusses the planned approach, including any additional steps that may be needed.
The procedure takes 60-90 minutes under general anaesthesia. Your surgeon works laparoscopically, carefully navigating any adhesions or anatomical challenges before creating the sleeve. In rare cases, conversion to an open procedure may be necessary for safety, your surgeon will discuss this possibility during your pre-operative consultation.
After Your Procedure
You spend 3-4 nights in hospital, one night longer than a standard sleeve to allow for more thorough monitoring. Your medical team checks for any complications, manages pain, and ensures you tolerate fluids. Walking is encouraged from the first day.
Once discharged, you recover at your 5-star hotel before your airport transfer. Your aftercare team provides the same comprehensive 12-month support as for any gastric sleeve patient.
Recovery & Aftercare
What to Expect During Recovery
Recovery from a complicated sleeve follows a similar timeline to a standard gastric sleeve, though the slightly longer hospital stay reflects the additional monitoring needed.
Days 1-4 (Hospital): Close observation, clear liquids, and gradual progression to protein drinks. Pain is managed with medication. Walking is encouraged from day 1, this is essential for preventing blood clots and aiding recovery.
Week 1-2 (Home): Liquid diet continues. Some patients experience slightly more discomfort than after a standard sleeve, particularly if adhesion removal was part of the procedure. Rest when you need to, but keep up light walking.
Week 2-4: Soft, pureed foods are introduced. Energy levels improve. Most patients return to desk-based work within 2-3 weeks. More physical roles may require 3-4 weeks.
Month 2-12: Gradual transition to normal foods in smaller portions. Weight loss follows the same trajectory as a standard sleeve, 60-70% of excess body weight lost within 12-18 months. Your 12-month aftercare programme supports you with dietary guidance, progress reviews, and direct access to your care team.
Vitamin Supplementation
As with any gastric sleeve, you will need daily multivitamins and specific supplements (B12, iron, calcium, vitamin D). Your aftercare team monitors your levels through regular blood tests.
Risks & Considerations
A complicated sleeve carries the same general risks as a standard gastric sleeve, with some additional considerations due to the complexity of the procedure.
Standard Sleeve Risks
- Nausea and discomfort in the first few days (managed with medication)
- Staple line leak (rare, approximately 1-2%, monitored during your hospital stay)
- Infection at incision sites (minimised by hospital hygiene protocols)
- Blood clots (reduced by early mobilisation and compression stockings)
- Nutritional deficiencies (managed with supplements and regular blood tests)
Additional Risks for Complicated Cases
- Longer procedure time increases general anaesthesia exposure slightly
- Higher chance of conversion to open surgery if laparoscopic access is not safe (this is a precaution, not a complication)
- Adhesion-related bleeding if significant scar tissue is present
- Slightly higher overall complication rate compared to straightforward cases (your surgical team factors this into their planning)
How Your Risk Is Managed
The additional hospital night in your package is specifically for enhanced monitoring. Your surgical team has experience with complex cases and adjusts their approach based on your individual anatomy. Pre-operative imaging and blood work help identify potential challenges before you reach the operating theatre.

Frequently Asked Questions
A sleeve is classified as complicated when factors such as previous abdominal surgery, a very high BMI, adhesions, or unusual anatomy make the procedure more technically demanding. This does not mean the procedure is unsafe, it means your surgical team needs additional expertise and planning. The outcome (weight loss, recovery) is the same as a standard sleeve. The "complicated" classification ensures your surgeon allocates extra time and resources for your specific case.
Yes. The weight loss results from a complicated sleeve are equivalent to a standard sleeve. Most patients lose 60-70% of their excess body weight within 12-18 months. The "complicated" classification refers to the surgical approach, not the outcome. Your smaller stomach will restrict your portions and reduce hunger hormones in exactly the same way. Your long-term results depend on following the dietary and lifestyle guidance from your aftercare team.
Potentially, yes. The surgical teams in The Health Store Turkey's network regularly operate on patients whose cases have been considered too complex by other providers. This includes patients with very high BMIs, multiple previous abdominal surgeries, or unusual anatomical features. Your free consultation includes a thorough assessment of your specific situation. If a gastric sleeve is not safe for you, your team will be honest about this and discuss alternative options.
The recovery timeline is similar to a standard sleeve, though you may spend an additional night in hospital for monitoring. Some patients who required adhesion removal or had a longer procedure experience slightly more discomfort in the first week. Overall, most patients feel ready for light activities within 7-10 days and return to work within 2-3 weeks. Your aftercare team provides personalised guidance based on the specifics of your procedure.
The higher cost reflects the additional surgical time, specialist expertise, and the extra night of hospital care included in your package. Complicated cases require more detailed pre-operative planning, longer theatre time, and enhanced post-operative monitoring. Despite the higher cost, the price remains significantly lower than in the UK, where complicated bariatric procedures can cost £10,000-£15,000 privately.
