Laparoscopic sleeve gastrectomy (LSG) is a restrictive procedure; the metabolic and endocrine effects of which remain unknown. Laboratories in North Dakota are certified as meeting the requirements of the Clinical Laboratory Improvement. We compared the effects of both procedures on glucose metabolism and fasting and meal-stimulated gut hormone levels.MethodsSeven patients were randomised to LRYGB and eight to LSG. Plasma levels of glucose, insulin, ghrelin, leptin, peptide YY (PYY), GLP-1 and pancreatic polypeptide were measured before and after 10 and 60A min of a standard test meal ingestion.ResultsAge, body mass index and preoperative hormone levels were similar in both groups. Moreover, a normalisation of homeostatic model assessment for insulin resistance value was also seen after both procedures.

In the LRYGB group, GLP-1 levels increased significantly after the test meal.ConclusionsLRYGB and LSG markedly improved glucose homeostasis.

All the studies were performed according to the principles of the Declaration of Helsinki and the Local Research and Ethics Committee at the Hospital del Mar approved the study. All patients provided written informed consent before enrolment.Preoperatively, the patients were allocated to LRYGB or LSG by computer-generated randomization.
Operations were performed by the same surgical team with experience in laparoscopic bariatric surgery. In LSG, a longitudinal resection of the stomach from 5A cm proximal to the pylorus to the angle of His was performed using a 36-French orogastric tube inserted along the lesser curvature.For the meal studies, subjects were admitted to our Clinical Trial Unit, IMIM-Hospital del Mar, before the operation, and at 3 and 12A months after surgery. On each occasion, an overnight fast of at least 12A h preceded insertion of an antecubital vein catheter for blood collection. After taking the fasting samples, a liquid test meal (EnsureA® containing 54% calories as carbohydrates, 16% as protein, and 30% as fat) was served to stimulate hormone release.
Drugs that could interfere with hormone assays, such as sitagliptine, vildagliptine, saxagliptine.
Plasma insulin concentrations were measured by radioimmunoassay (Linco Research Inc, St Charles, MO, USA). Clinical Laboratory Scientists are laboratory professionals who apply scientific skills and knowledge.
The intra-assay and inter-assay coefficients of variation were both less than 10%.GLP-1 was measured after extraction of plasma with ethanol using a commercially available kit (Linco Research, Inc, St Charles, MO, USA).

The antibody recognises shapes GLP7-36, GLP7-37, GLP9-36 amide, GLP9-37, GLP1 amide and GLP-1-36-37 amide, and binds specifically to the C-terminal portion of GLP-1 in both amidated and non-amidated forms. The sensitivity was 3 pM and the intra-assay and inter-assay coefficients of variation were 25 and 30%, respectively. There were no statistically significant differences in serum glucose levels between the two techniques at any study period. All four diabetic patients were able to withdraw antidiabetic drugs within the first 3A months postoperatively.Fig. 2Fasting plasma glucose (in milligrams per decilitre) a, insulin (microunits per millilitre) b and HOMA-IR index c in the two study groups [laparoscopic Roux-Y gastric bypass (LRYGB)a€”black and laparoscopic sleeve gastrectomy (LSG)a€”grey] before and 3 and 12A months after surgery.
Dashed line in c represents upper limit of normality in our population [12]No significant differences in preoperative fasting insulin levels and HOMA-IR index between the two groups were observed (Fig.A 2b, c). Postoperatively, fasting insulin levels were reduced significantly in both groups at 3A months after surgery. Preoperatively, ten patients fulfilled the criteria for insulin resistance (six patients in the LRYBP group and four patients in the LSG), and postoperatively all patients normalised their HOMA-IR values except one patient in the LSG group (Fig.A 2c). Although insulin plasma levels and HOMA-IR index were lower in the LRYGB, no significant differences between groups were detected.Gut Hormone LevelsPreoperative fasting ghrelin levels were similar in both groups (TableA 2).
After the test meal, although there was no statistically significance between groups, the pattern of ghrelin secretion was different. At 3A months, meal-stimulated levels were higher in the LRYGB without reaching statistical significance (TableA 2).
Some studies suggest that glycaemic control after LSG is achieved through a caloric restriction mechanism since the passage of nutrients through the proximal intestine is unchanged compared to LRYGB.This prospective randomised study provides preliminary evidence of the effects of laparoscopic RYGB and SG on glucose metabolism and gastrointestinal hormones comparing the response to a test meal before operation and 3 and 12A months postoperatively. In addition, HOMA-IR normalised in 14 of 15 patients at 3A months postoperatively with no differences between surgical procedures. Indeed, the two diabetic patients in the LSG group normalised blood glucose and insulin levels and being able to withdraw hypoglycaemic medication at 3A months, as happened with the two diabetic patients in the LRYGB group.
Other studies have demonstrated that LSG resulted in an early and dramatic improvement of glucose metabolism with superior glycaemic control than other restrictive techniques as adjustable gastric banding.21a€“23One possible explanation for these results could be as a consequence of limited caloric intake by small amounts of food eaten in the immediate postoperative period.
This would lead to a negative energetic balance conditioning, an improvement of glucose tolerance.
However, after surgery there is an increase in postprandial GLP-1 which cannot only be justified by caloric restriction since its secretion depends on the arrival of food into the distal small bowel.
Low levels of GLP-1 detected in obese patients may reflect the state of functional deficiency that contributes to poor glycaemic control in these patients.
An increase in postprandial GLP-1 level, in addition to its incretin effect, acts as a signal of satiety promoting weight loss.
The higher postprandial secretion of GLP-1 in LRYGB patients compared to the levels found after LSG could be explained by the earlier arrival of nutrients to the ileum in the first group. In obese patients, PYY levels are reduced and also have a lower response28 contributing to an increased appetite and impaired glucose tolerance.
Postoperative increased plasma PYY concentrations were detected in this study and may explain the weight loss and improved glycaemic control observed in our patients.
The normoglycaemia in these patients could be explained by the suppression of ghrelin production secondary to resection of gastric fundus. As it has been described by other authors,29, 31 there were significant differences between both techniques in the values of fasting ghrelin, with these levels being significantly lower in the LSG group at 3 and 12A months postoperatively.Leptin is an anorexigenic neuropeptide with considerable antagonistic satiating action of ghrelin and is mainly synthesised in adipose tissue.
This peptide increases after meals leading to gastric emptying, although it also inhibits the intestinal motility.43 In our study, the PP showed a similar pattern of secretion in both groups. Although the values of PP in patients undergoing LRYGB were higher than those of patients having LSG, the difference was not statistically significant.It should be noted that the present results, however, should be interpreted taking into account the small number of patients included in the study.


Further studies in a larger study population are needed to confirm these preliminary findings.
On the other hand, more pure nutrient sources or different volumes as well as solid foods were not tested, so that hormones responses to these challenges may be assessed in future studies.
Also, direction for further investigation would be to determine hormonal changes after longer postoperative periods.In summary, the present preliminary data suggest that LSG is more than a purely restrictive technique.
It has an antidiabetic effect in the early postoperative period as has been described by other authors.29, 31, 44 These results question the exclusion of the proximal intestine as an essential step to achieve improved glucose tolerance. Our study confirms that the postprandial response of ghrelin, GLP-1 and PYY is maintained in patients undergoing LSG, at least for 12A months after surgery similar to patients having LRYGB, and could explain the good results of surgery in relation to weight loss and glycaemic control.
