Arm Label

Sleeve gastrectomy

Roux-en-Y gastric bypass

Arm Description

200 obesity patients who undergo laparoscopic sleeve gastrectomy

200 obesity patients who undergo laparoscopic Roux-en-Y gastric bypass

Outcomes

Primary Outcome Measures

Obesity Cure Success Rate
Proportion of patients who reach BMI bellow 25
Body weight change rate
Decreased body weight proportion compare to preoperative body weight
Waist circumference change rate
Decreased waist circumference change proportion compare to preoperative waist circumference

Secondary Outcome Measures

Rate of morbid disease remission or partial remission
Remission rate or partial remission rate of morbid disease related to obesity such as hypertension, type 2 diabetes mellitus, hyperlipidemia after surgery
Postoperative complication rate and mortality rate
Number of participants surgical complications associate with the surgical technique or the operation field Number of participants mortality after operation associated with surgical complication or underlying disease
Micronutrient deficiency
Incidence of micronutrient deficiency rate such as vitamine, calcium, iron
Quality of life improvement rate and degree-1
Patients rate and quantitative analysis of the improved life quality using several survey EQ-5D-3L(EuroQol-5D) consists of 5 dimensions(mobility, self-care, usual activities, pain/discomfort and anxiety/depression). Each of which is scored as no/some/extreme problems. The dimension scores are converted into health utility scores ranging form 0(death) to 1(perfect health)
Quality of life improvement rate and degree-2
EQ-VAS(EuroQol-Visual Analogue scale) is a question scale ranging form 0 to 100. 0 indicated the worst and 100 indicated the best condition. EQ-VAS provides important, complementary information on patient's view about their own health.
Quality of life improvement rate and degree-3
Impact of Weight on QoL(IWQoL) has 5 dimensions and each dimension has several items. physical function : 11 items self-esteem : 7 items sexual life : 4 items public distress : 5 items work : 4 items Score range from 0 to 100 and 100 represents the best quality of life.
Quality of life improvement rate and degree-4
Moore-head-Ardelt QoL questionnaire II(MA-II) has 6 items(general self-esteem, physical activity, social contacts, satisfaction concerning work, pleasure related to sexuality and focus on eating behavior). All items are scored according to 10-level Likert scale(-0.5 to 0.5) and all have the same weight.
Quality of life improvement rate and degree-5
Obesity-related Psychosocial Problem scale(OP scale) consists of 8 items that measure the bothersome impact of body weight on given situations. (private gatherings in their own home, private gatherings at their friend or relative's home and going to restaurant)

5. Study Description

Brief Summary
Prospective, double-arm, multi-center cohort study on obese patients, for laparoscopic sleeve gastrectomy versus Roux-en Y gastric bypass
Detailed Description
This is prospective cohort study. Total 400 obese patients will be enrolled(Sleeve gastrectomy 200 patients, Roux-en-Y gastric bypass 200) The principal investigator or another clinical investigator in charge will individually inform the patients about the study, before operation at out patient clinic. At that time patient is selected to either sleeve gastrectomy group or Roux-en-Y gastric bypass group. All investigator report to clinical research center about patients BMI and operation method. About 30-35 obesity patients will be enrolled according to their BMI status. Patients' BMI status is classified into several parts by 2.5 gap started from 27.5. All patients will undergo periodically anthropometry, laboratory tests, bioelectrical impedance analysis, gastrofiberscopy, polysomnography and abdomen CT before and after surgery. Patients with hypertension will undergo echocardiography. Patients with polycystic ovary syndrome will be checked hormonal study. Patients with type 2 diabetes mellitus will be performed 75g oral glucose tolerance test test. Surgical complication include wound morbidities, gastrointestinal leakage or fistula, postoperative bleeding, intra-abdominal abscess, stricture , adhesive ileus, reflux esophagitis, marginal ulceration, dumping syndrome and internal hernia. Systemic complication which is not associated with the operation field include ling morbidities, heart morbidities, urinary morbidities and others. Hospital mortality is defined as postoperative death form any cause within 30 days after operation. All patients will be followed up post operative 1 month, 3 month, 6 month, 12 month, 18 month, 24 month. All patients' liver tissue, visceral fat and subcutaneous fat will be harvested during operation. All patients' blood sample will be collected at out patient clinic visit. All patients' urine and face will be collected at out patient clinic visit and will be analyzed to evaluate microbial change throughout pre and post operation period.
