Plain English summary of protocol
Background and study aims
Weight loss surgery, also called bariatric or metabolic surgery, is sometimes used as a treatment for people who are very obese. It can lead to significant weight loss and help improve many obesity-related conditions, such as type 2 diabetes or high blood pressure. But it's a major operation and in most cases should only be considered after trying to lose weight through a healthy diet and exercise.
This study aims to test the safety of a new procedure that combines elements of existing procedures.
Who can participate?
Patients aged over 18 and below 65 years with BMI over 40 kg/m² (without comorbidity related to morbid obesity) or 35 kg/m² (with comorbidity related to morbid obesity, especially glucose metabolism)
What does the study involve?
Patient assessment, performing surgery, and follow up at 1, 3, 6 and 12 months postoperatively.
What are the possible benefits and risks of participating?
Favourable weight loss management is expected due to reducing stomach volume and duodeno-jejunal exclusion but operations may have some risks (gastric wall prolapse, leakage, stricture, bleeding, bile reflux, vomiting, diarrhea, hair loss, nutrient deficiency, hypoproteinaemia and anaemia due to malabsorption)
Where is the study run from?
Kanizsai Dorottya Hospital (Hungary)
When is the study starting and how long is it expected to run for?
October 2018 to October 2020
Who is funding the study?
Kanizsai Dorottya Hospital (Hungary)

| Scientific title | LAparoscopic Single-Anastomosis duodeno-ileal bypass with Gastric plication (SADI-GP) in the maNagEment of morbid obesity (LASAGNE) |
| Study acronym | LASAGNE |
| Study objectives | Laparoscopic single-anastomosis duodeno-ileal bypass with gastric plication is expected to be a safe procedure and have low complication rates and favourable weight loss outcomes. |
| Ethics approval(s) | Approved 05/07/2019, Kanizsai Dorottya Hospital (Hospital of Nagykanizsa) Institutional Review Board (8800, Nagykanizsa, Szekeres, J.u. 2-8, Hungary; +36 93502092; titkarsag@nkkorhaz), ref: KDK-2071-2/2019 |
| Health condition(s) or problem(s) studied | Laparoscopic surgery for severe obesity and related metabolic disorders |
| Intervention | Patients were operated on to perform laparoscopic single anastomosis duodeno-ileal bypass with gastric plication. Follow-ups were at 1, 3 and 6 months and are planned at 12 months. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure(s) |
Postoperative complications (gastric wall prolapse, leakage, stricture, bleeding, bile reflux, vomiting, diarrhea, hair loss, nutrient deficiency, hypoproteinaemia and anaemia due to malabsorption, venous thromboembolism, pulmonary and cardiovascular events, 30-day hospital readmission) were classified by Clavien-Dindo |
| Key secondary outcome measure(s) |
At follow up visits (1,3,6 and 12 months), patients were assessed again by physical examination, blood tests (blood count, ionogram, serum protein, glucose, HgbA1C, iron binding capacity, lipid profile, kidney and liver function, hemostasis) and BAROS-Moorehead-Ardelt II and Weiner et al. questionnaires. Weight, BMI adjusted to age-gender-ethnics, ideal weight (at BMI: 25), excess of weight, excess of BMI, weight loss, EWL% and TWL% were measured as weight loss outcomes |
