Predictors of early withdrawal from follow-up visits after laparoscopic sleeve gastrectomy in a Japanese institution

Background and Aims: The aim of this study was to evaluate the long-term (5-year follow-up) results of laparoscopic sleeve gastrectomy in terms of weight loss and obesity-related comorbidities, as well as the risk factors associated with postoperative nutritional deficiencies. Material and Methods: The first 99 consecutive patients who underwent laparoscopic sleeve gastrectomy for the treatment of morbid obesity between October 2008 and August 2011 at Tartu University Hospital were followed prospectively in cohort study. The outpatient hospital follow-up visits were conducted at 3 months, 1 year, and 5 years postoperatively. At 5 years, the follow-up rate was 90.9%; 86 laparoscopic sleeve gastrectomy patients were included in final analysis. Results: The mean excess weight loss (%EWL) was 44.3% ± 13.0%, 75.8% ± 23.1%, and 61.0% ± 24.3% at 3 months, 1 year, and 5 years, respectively. A linear association between preoperative weight and weight at 5 years was found. Remission rates at 5-year follow-up for type 2 diabetes, hypertension, dyslipidemia, and obstructive sleep apnea were 68.8%, 32.7%, 27.4%, and 61.5%, respectively (all p < 0.05). There was a statistical difference (p < 0.05) in the dynamics of triglyceride, low-density lipoprotein, and high-density lipoprotein level at 5-year follow-up but the level of total cholesterol did not show significant improvement. The risk for cumulative iron, vitamin B12 deficiency, and anemia was 20%, 48%, and 28%, respectively. Conclusion: In conclusion, laparoscopic sleeve gastrectomy ensured long-term excess weight loss 61.0% at 5 years. Laparoscopic sleeve gastrectomy has a long-term effect on significant improvement in the median values of triglycerides, low-density lipoproteins, and high-density lipoproteins, but not on total cholesterol levels. There is a risk of postoperative vitamin B12 and iron deficiency.

Background: Currently, the two most common bariatric procedures are laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). Long-term data comparing the two interventions in terms of their effect on body composition and bone mass density (BMD) are scarce. Objective: The aim of this study was to assess body composition and BMD at least 5 years after LSG and LRYGB. Setting: Department of Endocrinology and Nutrition, St. Claraspital Basel and St. Clara Research Ltd., Basel, Switzerland. Methods:Bariatric patients at least 5 years after surgery (LSG or LRYGB) were recruited, and body composition and BMD were measured by means of dual-energy X-ray absorptiometry. Data from body composition before surgery were included in the analysis. Blood samples were taken for determination of plasma calcium, parathyroid hormone, vitamin D3, alkaline phosphatase, and C-terminal telopeptide, and the individual risk for osteoporotic fracture assessed by the Fracture Risk Assessment Tool score was calculated. After surgery, all patients received multivitamins, vitamin D3, and zinc. In addition, LRYGB patients were prescribed calcium. Results: A total of 142 patients were included, 72 LSG and 70 LRYGB, before surgery: median body mass index 43.1, median age 45.5 years, 62.7% females. Follow-up after a median of 6.7 years. For LRYGB, the percentage total weight loss at follow-up was 26.3% and for LSG 24.1% (p = 0.243). LRYGB led to a slightly lower fat percentage in body composition. At follow-up, 45% of both groups had a T score at the femoral neck below –1, indicating osteopenia. No clinically relevant difference in BMD was found between the groups. Conclusions:At 6.7 years after surgery, no difference in body composition and BMD between LRYGB and LSG was found. Deficiencies and bone loss remain an issue after both interventions and should be monitored.

Abstract Background The incidence of obesity has been constantly growing and bariatric procedures are considered to be the most effective treatment solution for morbidly obese patients. The results of laparoscopic sleeve gastrectomy (LSG) may differ depending on patient’s age, gender, preoperative body mass index (BMI) and physical activity. Methods The aim of this study was to evaluate age-related differences in the outcome of LSG in terms of weight loss parameters, lipid and carbohydrate profile. The retrospective analysis of 555 patients who had undergone LSG was performed to compare the metabolic outcomes of surgery in individuals < 45 and ≥ 45 years old. Evaluation of weight loss parameters along with selected laboratory data was performed to demonstrate the results of LSG in 2 years follow-up. Results Overall, 238 males and 317 females (43%/57%) with median age of 43 years and median preoperative BMI of 46.41 (42.06–51.02) kg/m2 were analyzed. Patients in both groups presented significant weight loss at 24 months after the surgery with comparable percentage of total weight loss (40.95% in < 45 years old group and 40.44% in ≥ 45 years old group). The percentage of excess weight loss (78.52% vs. 74.53%) and percentage of excess BMI loss (91.95% vs. 88.01%) were higher in patients < 45 years old. However, the differences were not statistically significant (p = 0.662, p = 0.788 respectively). Patients under 45 years old experienced faster decrease in fasting glucose level that was observed after only 3 months (109 mg/dl to 95 mg/dl in < 45 years old group vs. 103.5 mg/dl to 99.5 mg/dl in ≥ 45 years old group, p < 0.001). Both groups presented improvement of lipid parameters during the observation. However, patients < 45 years old achieved lower values of LDL at 3 and 12 months follow-up (115 mg/dl vs. 126 mg/dl, p = 0.010; 114.8 mg/dl vs. 122 mg/dl, p = 0.002). Younger group of patients also showed superior improvement of triglycerides level. Conclusions LSG results in significant weight loss in all patients regardless age. In turn, superior and faster improvement in lipid and carbohydrate profile is achieved in patients under 45 years old.

Bariatrische Operationen

In den letzten Jahren wurden die Ergebnisse randomisierter kontrollierter Studien publiziert, die im 5-Jahres-Verlauf die metabolischen Effekte der bariatrischen Chirurgie mit konventionellen Formen der Gewichtsreduktion vergleichen. Diese Studien zeigen unisono, dass die bariatrische Chirurgie hinsichtlich der Besserung der diabetischen Stoffwechsellage den konventionellen Behandlungsformen signifikant überlegen ist. Die Diabetesremissionsraten variieren abhängig von Ausgangsparametern, Operationsmethode und Follow-up-Dauer zwischen 95 und 23 %.Ist Diabetes heilbar durch bariatrische Chirurgie? Die klare Antwort muss lauten: Nein, aberInsofern ist die bariatrische Chirurgie in Form von Roux-en-Y Gastric Bypass (RYGB), Laparoscopic Sleeve Gastrectomy (LSG) und den neueren Verfahren wie Omega Loop Bypass („Mini-Bypass“) oder biliopankreatische Diversion (BPD) eine wirkungsvolle therapeutische Option in der Behandlung des Diabetes mellitus Typ 2 und verringert offenbar auch das Risiko des Auftretens von mikrovaskulären Diabetesfolgekomplikationen. Je früher im Krankheitsverlauf die bariatrische Chirurgie SSherangezogen wird, desto effektiver scheinen diese Verfahren zu sein.Welche der Operationen für Patienten mit Typ-2-Diabetes am besten geeignet ist, ist derzeit nicht definitiv entschieden. Der RYGB scheint etwas effektiver zu sein. Die Verfahren der bariatrischen Chirurgie gehören in das Spektrum der differenzialtherapeutischen Überlegungen insbesondere bei adipösen Patienten mit Typ-2-Diabetes mit einem BMI > 35 kg/m².Die Mechanismen der Verbesserung der diabetischen Stoffwechsellage durch bariatrische Operationen werden anhand der aktuellen Literatur detailliert beschrieben. Die Indikationen, Kontraindikationen, Komplikationen und Therapiealgorithmen der bariatrischen Chirurgie bei Typ-2-Diabetes sind in den entsprechenden Leitlinien ausführlich dargestellt und nicht Gegenstand dieser Publikation.
