Brief Summary

Obesity, which is defined as the accumulation of fat in the body to a degree that impairs health, is defined as a serious public health problem and it is estimated that 13% (approximately 650 million) of the entire world population is obese. There are different methods in the fight against obesity, one of these methods is bariatric interventions. Although bariatric surgery is the most effective of these procedures, the tendency to endoscopic methods is increasing due to the surgical risk. Gastric balloon is the most common endoscopic method. In addition, gastric botox is among the methods used. Health consequences of endoscopic interventions have been widely investigating and while gastric balloon recommended as safe and effective method, the situation for gastric botox is controversial. Although it seems as gastric balloon is an office procedure and safely performed, especially the first week is difficult process for patients. It can also end with abdominal pain, nausea, retching, and eventually a process leading to premature removal of the balloon. In Italian study, Genco et al. reported that out of 2515 patients 11 patients (0.44%) balloon removed due to psychological intolerance. While the reported rate of early gastric balloon removal generally ranges from 0.44% to 16%, De Castro ML. et al. reported the early removal rate as 20%. While the complications related to the gastric balloon are as stated, problems such as nausea, vomiting and cramps after the gastric botox procedure are either not reported or not seen at all. Therefore, we hypothesize that sequential endoscopic procedures (first botox application followed by gastric balloon placement) will reduce these early complications (abdominal pain, nausea, retching) and early removal of the gastric balloon. The only study we have reached regarding combined therapy was done in Turkey. Kanlıöz M et al. reported that combining botox and balloon was found to be more effective in losing weight, but it was stated that it had more side effects. In this study, we think that the side effects may already be related to the balloon. As James A et al. stated in their experimental work, the effectiveness of botox is time dependent. It has been stated that the efficacy is optimal after 6 hours in injections to the pyloric region.The fact that the balloon was inserted in the same session, without waiting for enough time after the botox procedure to be effective, may have reduced the possible protective effect of the botox.

Outcome Measures

Primary Outcomes (5)

  • Number of patients who develop intolerance and undergo balloon removal procedure

    Number of patients who develop intolerance and undergo balloon removal procedure

    First 6 months after intragastric balloon placement

  • Quality of life measured using SF-36 questionnaire

    The acute(1 week) time frame format of Short Form-36 questionnaire will be used to assess health-related quality of life

    The questionnaire will be taken 1 week after the balloon placement

  • Nausea-vomiting and retching measured using Rhodes index of nausea-vomiting-retching(RİNVR)

    The questionnaire will be taken 6 hours after intragastric balloon placement

  • Number of analgesics and muscle relaxants needed

    First week after intragastric balloon placement

  • Weight loss

    6 months after intragastric balloon placement

Study Arms (2)

Only gastric balloon

EXPERIMENTAL

After analgesia endoscopy will be performed. After diagnostic endoscopy if there is no any gastric pathology that would be contraindication for balloon placement a gastric balloon will be placed. For first day standard medication will be provided. Starting from first hour until 1 week, patient nausea -vomiting and retching scores, re-admission to hospital, quality of life scores will be documented. After analgesia endoscopy will be performed. After diagnostic endoscopy if there is not any gastric pathology that would be contraindication for balloon placement a gastric balloon will be placed. For first day standard medication will be provided. Starting from first hour until 1 week, patient nausea -vomiting and retching scores, re-admission to hospital, quality of life scores will be documented.

Procedure: gastric balloon implantation

sequential botulinum toxin A injection and then gastric balloon

EXPERIMENTAL

After analgesia endoscopy will be performed. After diagnostic endoscopy if there is not any gastric pathology that would be contraindication for Botox injection and balloon placement, 200 U of botulinum toxin A will be injected to the antrum and the fundus. After 24 hour or 1 week the second procedure (placement of gastric balloon) will be performed. And Starting from first hour until 1 week, patient's nausea-vomiting and retching scores, re-admission to hospital, quality of life scores will be documented.

Procedure: gastric balloon implantationProcedure: botulinum toxin A injection

Interventions

After diagnostic endoscopy if there is no any gastric pathology that would be contraindication for balloon placement a gastric balloon will be placed

Only gastric balloonsequential botulinum toxin A injection and then gastric balloon

After diagnostic endoscopy if there is no any gastric pathology that would be contraindication Botox injection and balloon placement, 200 U of Botox A will be injected to antrum and fundus. And 1 week later gastric balloon will be implanted

Also known as: Gastric balloon implantation 1 week after Botox injection
