2. Research question
What are 30-day morbidity and mortality after laparoscopic sleeve gastrectomy in an Egyptian practice?
3. Study design and population
- Study design
- Case series / case report – Retrospective single-surgeon series with prospectively collected data
- Population
Patients undergoing LSG by one surgeon in Cairo
- Country
Egypt
- Period
July 2011-August 2022
- Sample size
892
- Inclusion and exclusion criteria
All LSG by the same surgeon
4. Methods and endpoints
- Exposure / intervention
Laparoscopic sleeve gastrectomy
- Comparator
None (risk-factor analysis)
- Endpoints
30-day morbidity, reoperation, mortality
- Statistical methods
Descriptive; regression for risk factors
5. Actual results
- Results
Early adverse events 16 (1.79%); transfusion 1.35%; ICU 0.22%; reoperation 0.9% (8); mortality 0.22% (2/892). BMI, hypertension and revisional surgery predicted morbidity.
- Absolute risks
30-day mortality 2/892 (0.22%).
- Authors' conclusion
Confirms short-term safety of LSG; BMI, hypertension and revisional surgery are risk factors.
6. Strengths
- Egyptian data
- Consecutive series over 11 years
7. Weaknesses
- Single surgeon, no control group
- Retrospective
- Short-term only
8. Risk of bias
- Orienting tool
- none applicable
- Type of assessment
- simplified assessment (abstract only)
- Full formal assessment
- no
- Overall risk of bias
- high
- Rationale
Case series; selection and reporting bias possible.
9. Assessment of the statistical interpretation
2/892 = 0.22%; higher than the pooled 0.05% for sleeve (I-BAR-103), but imprecise (2 events).
10. Relevance to the specific claim
Regional (Egyptian) estimate of early mortality after sleeve; deaths are rare but occur.
11. Independent contrary findings
Single centre; cannot represent all Egyptian practice.
12. Transferability to Germany and Europe
Egyptian setting; not EU.
13. Overall methodological judgement
Low-quality but regionally relevant confirmation that early death is rare.

14. Open questions
National Egyptian registry data are lacking.
15. Linked fact checks
- Sleeve gastrectomy (and bariatric surgery in general) is a lethal operation that kills patients / shortens life. – Studies with mixed or unclear results
