Clinical Trial Summary

Obesity is a major public health problem worldwide. Bariatric surgery has proved to be the most effective treatment of morbid obesity in terms of weight reduction and remission of co-morbid conditions during long-term follow-up. Sleeve Gastrectomy (SG) has become the most performed intervention either worldwide or in France, where SG represents more than 60% of bariatric interventions and 114,817 patients operated between 2013 and 2016. Maximum Excess weight loss (%EWL) after SG is obtained at one-year post surgery. Then it has been largely reported in the literature that patients could present mild, moderate or important (notably in the super obese patients) weight regain associated with comorbidity relapse motivating redo surgery. Like in revisional surgery, operating super-obese patient (BMI ≥50 kg/m2) is a challenge. It has been shown that achieving significant weight loss was more difficult in patients with a BMI ≥ 50 compared to lower BMIs.


Description:

In these 2 populations of patients, more malabsorptive procedures like long limb One Anastomosis Gastric Bypass or Bilio-Pancreatic Diversion with Duodenal Switch could be more efficient but induce technical difficulties (high complication rate) and can be responsible for malnutrition (vitamin deficiencies, hypoalbuminemia…). That's why, in case of revisional surgery or for high BMI patients,laparoscopic Roux-en-Y gastric bypass (RYGBP) is still considered as the gold standard and is the most performed intervention. To obtain better weight loss safely,Santoro et al. promoted the sleeve gastrectomy with transit bipartition (SG+TB), a new intervention coupling a SG without interrupting pathway through the duodenum and preserving the pylorus and a long biliary limb RYGBP. Hypothesis: Because there is no duodenal and jejunal exclusion, malnutrition is expected to be less frequent after SG+TB compared to BPD/DS. Its anastomosis on the antrum makes SG+TB easier to perform in super-obese patient than standard RYGB but more efficient in term of weight loss. Compared to BPD/DS or SADI which involves dissection of the duodenum and the confection of a duodenojejunostomy, SG+TB is also expected to be easier then safer.

Intervention

Procedure:
sleeve gastrectomy with transit bipartition (SG +TB)
In case of a first intention procedure, a typical sleeve gastrectomy is performed, calibrated on a 36 French bougie, stapling starting 4 to 6 cm from the pylorus. Antecolic gastroileal anastomosis is performed 250 cm from the ileocecal transition, on the antrum using a linear stapler (45-mm gold cartridge) or hand-sewn (at least 3 cm wide on the stomach). Laterolateral enteroanastomosis is performed 120 cm from the ileocecal junction. Thus, alimentary limb is 130cm and common limb 120cm.
Roux-en-Y gastric bypass (RYGB)
A small gastric pouch (30 cc) is performed. Antecolic gastroileal anastomosis is performed 200 cm from the Treitz junction, using a linear stapler (45-mm gold cartridge) or hand-sewn (at least 3 cm wide on the stomach). Laterolateral enteroanastomosis is performed 50 cm from the Treitz junction. Thus, alimentary limb is 150cm and biliary limb 50cm.

Outcome

Type Measure Description Time frame Safety issue
Primary The Excess Weight Loss percentage (EWL%) The Excess Weight Loss percentage (EWL%) calculated with the following formula: ((weight at 2 years visit - initial weight (kg)) / (initial weight - ideal weight)) X 100 Ideal weight defined as the weight corresponding to a BMI = 25 kg/m2. Initial weight defined as preoperative weight at V1. All weights are expressed in kg at 2 years after surgery
Secondary Change nutritional status assessment Nutritional profil : Hemoglobin (g/l), albumin (g/l), prealbumin (g/l) from baseline (before surgery) to 24 months after surgery
Secondary Change in liver status assessment Liver parameters ( ALT AST GGT Alkaline phosphatases, Total bilirubin, prothrombin time, urea, creatininemia concentration) from baseline (before surgery) to 24 months after surgery
Secondary Change in vitamins status assessment vitamins profil (vitamin A B1, B6 B9, B12, C , D and E concentration) from baseline (before surgery) to 24 months after surgery
Secondary Change in mineral status assessment Mineral profil ( ferritin, potassium, calcium,iron, transferrin, magnesium, selenium, zinc phophore concentration) from baseline (before surgery) to 24 months after surgery
Secondary 24-hour steatorrhea quantified at 6 months 24-hour steatorrhea is assessed to evaluate denutrition, expressed in g of lipid/24hr At 6 months
Secondary Evolution of muscle mass assessed by bioelectrical impedance analysis muscle mass is assessed to evaluate denutrition. from baseline to 24 months after surgery

Secondary Evolution from baseline to 24 months after surgery of HbA1c level, HDL, LDL and triglycerides Evolution from baseline to 24 months after surgery of HbA1c level (expressed in %), fasting glycemia (expressed in mmol/l or g/l), HDL (expressed in mmol/l or g/l), LDL (expressed in mmol/l or g/l) and triglycerides (expressed in mmol/l) from baseline to 24 months after surgery
Secondary Evolution from baseline to 24 months of insulinoresistance defined by HOMA-IR calculated with fasting blood glucose and fasting insulinemia12 assessment of insulinoresistance from baseline to 24 months
Secondary Change of the GIQLI score This questionnaire consists of 36 items exploring 5 dimensions or subscales: symptoms, physical condition, emotions, social integration and the effect of any medical treatment. For each item, 5 responses will be proposed to patients and for each answer, a score is assigned, ranging from 0 to 4 (highest score = 144). A high score defines a more favorable health state from baseline to 24 months after surgery
Secondary Change of the SF36 scores This questionnaire taps eight health concepts: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. It also includes a single item that provides an indication of perceived change in health. from baseline to 24 months after surgery
Secondary Change in Sigstad questionnaire score (dumping syndrome). The Sigstad questionnaire allows the identification and diagnosis of postoperative hypoglycemia: a score > 7 suggests a dumping and a score <4 suggests another diagnosis.
Complementary questions regarding timing of dumping (<30 min or >1h30) will be asked if Sigstad score >7.
from baseline to 24 months after surgery
Secondary Change of food choices and preferences assessed by the Leeds Food Preference Questionnaire (LFPQ) score. The Leeds Food Preference Questionnaire provides measures of different components of food preference and food reward. Participants are presented with an array of pictures of individual food items common in the diet. Foods in the array are chosen by the experimenter from a validated database to be either predominantly high (>50% energy) or low (<20% energy) in fat but similar in familiarity, protein content, sweet or non-sweet taste and palatability. Outcome measured are explicit Liking, explicit wanting, implicit wanting and food choice.
Scores for explicit liking and explicit wanting range from 0-100 with a typical mean (±S.D.) of 60±18 Scores for Food Choice range from 0-48 and have a typical mean of 24±10 or for the appeal bias range from -48-48 with a typical mean of -5±15.
Scores for Implicit Wanting typically range from -100-100 (due to RT there is no fixed min-max value) and have a typical mean of ±10±25 or for the appeal bias a typical mean of -10±30.
from baseline to 24 months after surgery
Secondary Change of physical activity assessed by the International Physical Activity Index (IPAQ) score. The International Physical Activity Questionnaire assesses the types of intensity of physical activity and sitting time that people do as part of their daily lives to estimate total physical activity in MET-min/week and time spent sitting. from baseline to 24 months after surgery
