Abstract

The intragastric balloon is an effective method for weight reduction in obese people. The common problem of intragastric balloon insertion is a blind performance. Practitioners cannot see the insertion from oral cavity to the stomach clearly. To overcome this point, side attachment method was developed. The introduction kit is attached to the shaft of the endoscope side by side, so the introduction kit does not cover the camera of an endoscope. Side attachment method provides clear field of vision during insertion from oral cavity to the stomach, same to diagnostic endoscopy.

Introduction

The intragastric balloon (IGB) technique has become an effective and safe method of achieving significant weight reduction in obese people. IGBs allow patients to feel fullness and finally decrease their food intake. IGBs replace gastric luminal volume and may distend the stomach, potentially inducing neurohormonal effects and changes in motility [-5]. Most IGBs are blindly inserted into the stomach without endoscopic guide, finger technique [6]. End-Ball® (Endalis, Brignais, France) uses endoscope as a guide for passage of the balloon into the stomach; however, the endoscopic view is nearly blind because an introduction kit covers the camera of an endoscope, front attachment method. The common problem of these procedures is a blind performance. If a practitioner can insert an introduction kit with diagnostic visual field, insertion procedure will be easier and safer; blind insertion can damage oral cavity and gastrointestinal tract involuntarily.

Side Attachment Method

Side Attachment Method (SAM) was developed to provide clear visual field during insertion. In SAM, the introduction kit is attached to the shaft of the endoscope side by side, so the introduction kit does not cover the camera of an endoscope. Additionally, SAM with J turn allows a practitioner to notice that an introduction kit is in the stomach. SAM with J turn also enables a practitioner to watch inflation process time to time [8].

Practice of Side Attachment Method

    i. A 3.5cm X1cm sized window is made at the distal part of the pouch for releasing a balloon before side attachment to an endoscope.

    ii.The endoscope was then connected to the introduction kit by side attachment method (Figure 1). The opposite side of the window is attached to the scope by 2.5cm width paper plaster, so the widow is placed at the opposite direction of attached side. The tip of the pouch is attached to the point 2cm distal to the end of the scope, and the catheter is attached to the points 20cm and 30cm distal to the end of the scope

    iii. Inserting the endoscope with introduction kit as a diagnostic endoscopy insertion. While passing through the oral cavity, the pyriform sinus, the esophagus, all structures were clearly observed as diagnostic endoscopy.

    iv. After inserting an introduction kit into the stomach, J turn is used to confirm whether the introduction kit is in the stomach (Figure 2a).

    v. The balloon begins to be filled. When 100 cc air and 150 cc saline were applied, the balloon was pushed out of the pouch; J turn also shows this process (Figure 2b) and filled with saline to its designated volume (600 cc) under endoscopic control.

    vi. After then, a feeding catheter was pulled up with an endoscope at the cardia, and the IGB was disconnect from the feeding catheter.

    vii. Finishing implantation, follow up endoscopy revealed that the IGB was well placed in the fundus (Figure 3).

Conclusion

SAM is a very useful technique for implanting IGB. Ordinary front visual field during insertion is a pivotal advantage of SAM. Conventional technique caused nearly blind insertion, so practitioners cannot but rely on tactile sensation instead of visual sensation. SAM is a reasonable choice for easy and safe IGB implantation.

A Modified Sequential Regimen of Helicobacterpylori Treatment Enforced by Bacillus clausii and Zinc Carnosine Complex Yields High Eradication Rates_Juniper Publishers

  ADVANCED RESEARCH IN GASTROENTEROLOGY & HEPATOLOGY JUNIPER PUBLISHERS   Authored by Dajani AI      Abstract Introduction: Over the past decade a worldwide trend of decline in the cure rates of Helicobacter pylori is observed. Current eradication rates achieved by the standard triple therapy are below 70%. Sequential therapy had provided a potential alternative that would compensate for the unmet performance of triple therapy. Despite its superiority to triple therapy, the excellent results reported initially were not reproduced by other investigators work. Adding adjuvant agents was also found to improve further the success rate of eradication. Probiotics emerged as a useful adjunct in treatment and prophylaxis of Helicobacter pylori infection. The nutritional supplement Zinc carnosine complex is another adjuvant which is believed to add value to the treatment. Patients and method: an open label randomized observational clinical study ...

Association between Nonalcoholic Fatty Liver Disease and Carotid Atherosclerosis-Juniper Publishers

JUNIPER PUBLISHERS-ADVANCED RESEARCH IN GASTROENTEROLOGY & HEPATOLOGY Abstract Aim/Background: Nonalcoholic fatty liver disease (NAFLD) frequently accompanies to the criteria of Metabolic Syndrome (MetS) like obesity, diabetes, and dyslipidemia. It is recently approved as a liver attaint of MetS. While MetS is a highly atherogenic condition we examined whether NAFLD was associated with atherosclerosis, as measured by ultrasound in the carotid arteries. Methods: Carotid intima-media thickness and cardiovascular risk factors were evaluated in 64 patients with an ultrasound diagnosis of primary NAFLD and 64 matched population controls. Metabolic syndrome was established according to WHO and ATP-III criteria. IMT values were evaluated according to protocols of standard measurements of carotid artery. Results: The metabolic syndrome and all its individual features were significantly (P<0.001) more frequent in NAFLD patients than in control subjects. P...

      ADVANCED RESEARCH IN GASTROENTEROLOGY & HEPATOLOGY JUNIPER PUBLISHERS     Authored by Nishant Shukla    Abstract Liver cancer has become the second largest cancer death rate in the world, and the prevention and treatment of liver diseases is extremely urgent. It has grown up to be a hot spot and focus of the world. With the development of medical imaging and the introduction of “precise surgery”, the development of preoperative planning system for liver diseases has become a research hotspot. Accurate preoperative planning system relies on the development of image processing technology, and the introduction and application of deep learning just improve the accuracy of image processing technology and promote the development process of liver preoperative planning system. This paper mainly expounds the main problems of today’s deep learning-based liver preoperative planning system and discusses the solution to the problem and th...
