About this study

Official title: Effect of Laparoscopic Sleeve Gastrectomy (LSG) Plus Uvulopalatopharyngoplasty and Adenoidectomy/Tonsillectomy on Severe Obstructive Sleep Apnea & Hyponea Syndromes in Moderate-to-severe Obese Patients: an Open-label Randomized Controlled Clinical Trial

This research is created for compare the difference of AHI variation between LSG and combined surgery on obstructive sleep apnea in obese patients , evaluate the risk of combined surgery and explore the correlative factor of the curative effect.

Read the detailed description

Obesity is one of the new health challenges in China and all over the world,Morbidly obesity (MO) is an important risk factor for metabolic diseases and obstructive sleep apnea(OSA), which can be effectively and lastingly reduced by bariatric surgery.

OSA is the most common type of sleep apnea and is caused by complete or partial obstructions of the upper airway. It is characterized by repetitive episodes of shallow or paused breathing during sleep, and is a potentially fatal disease. OSA has complex pathogenesis and numerous pathogeny, while morbidly obesity is one of the important risk factors of OSA. Previous research has shown that the incidence of OSA will rise by 1.14 % while body mass index(BMI) rise by 1%.Therefor, loseing weight is highly recommend for morbidly obese patients with OSA in clinical guideline for OSA both in USA and China, and bariatric surgery is effective for morbidly obese patients with OSA. Most yellow race morbidly obesity patients have abdominal obesity which is different from the white race,while Abdominal obesity is associated with greater incidence and more severely of OSA. There are maybe twenty million patients with OSA and 80% of them haven't been diagnosed.

At present,. Laparoscopic sleeve gastrectomy(LSG) and laparoscopic Roux-en-Y gastric bypass(LRYGB) are two of the main bariatric surgical procedures performed in China. They can performed as one stage each or multiple sessions(LSG-LRYGB) which is depend on the severity of obesity and its complications.

UPPP was first performed in 1981 by doctor Fujita and modified these years, it has been a standardized treatment for OSA. The effective rate of UPPP is less than 65% and is associated with the BMI and age of patients , younger and lower BMI means better effect. Consideration of the discontented outcome in obese patients, Simple UPPP is not recommended for OSA patients with morbidly obesity in clinical guidelines for OSA.

Although simple LSG has a sure prostecdtive efficacy for both OSA and morbidly obesity, patients still need CPAP during several months after surgery. So we chosed patients who conformed the surgical indications of both morbidly obesity and OSA,and performed an combined surgery (LSG+UPPP+adenoidectomy/tonsillectomy). We found that combined surgery has a better short-term efficacy than simple LSG, so the randomized clinical trial(RCT) was designed to explore the efficacy of combined surgery in the treatment of severe OSA in moderate-to-severe obese patients.

Being tested
Laparoscopic sleeve gastrectomy(LSG), Uvulopalatopharyngoplasty(UPPP) and Adenoidectomy/Tonsillectomy

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Laparoscopic sleeve gastrectomy(LSG)Procedure or surgery

    LSG:All these operations were performed by the same surgeon team. Dissect the greater omentum alongside the greater gastric curvature, make sure that the greater gastric curvature and fundus of stomach were completely made free from pancreas and spleen.Fully Exposed left and right diaphragm angle and taking care not to injure the esophagus. Resection was started 2 to 4 cm from pylorus and alongside a 40Fr tube up to the esophagogastric junction and created a 60 to 80ml gastric lumen, removed the fundus of stomach thoroughly and take care of the esophagus and preventriculus. Repaired the hiatal hernia if it was exsit.

  • Uvulopalatopharyngoplasty(UPPP) and Adenoidectomy/TonsillectomyProcedure or surgery

    UPPP:PPP is typically administered to patients with obstructive sleep apnea in isolation. It is administered as a stand-alone procedure in the hope that the tissue which obstructs the patient's airway is localized in the back of the throat. The rationale is that, by removing the tissue, the patient's airway will be wider and breathing will become easier.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The mean change in Apnoea-Hypopnoea Index (AHI)

    The mean change in AHI

    Measured: At the 6 month after surgery

Secondary outcomes (6)
  1. Time to response

    AHI reduse to 50% of the base line

    Measured: during 6 months after surgery

  2. Other PSG measures: average and lowest blood oxygen saturation at night

    in psg report

    Measured: At the 6 month after surgery

  3. Weight, BMI

    Measured: At the 6 month after surgery

  4. neck,chest,waist hip and biceps circumference

    Measured: At the 6 month after surgery

  5. Epworth Sleepiness Scale (ESS) scores

    Measured: At the 6 month after surgery

  6. Changes in the CT scan of upper airway and head radiography

    Measured: At the 6 month after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Laparoscopic sleeve gastrectomy(LSG) and Uvulopalatopharyngoplasty(UPPP) and Adenoidectomy/Tonsillectomy in people with To Compare the Difference of AHI Variation Between LSG and Combined Surgery, run by Bing Wang.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 24 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?

Contact Bing Wang, M.D. (+86-15821423382, wingping01@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The mean change in Apnoea-Hypopnoea Index (AHI) (time frame: At the 6 month after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
