This video demonstrate How to do Safe Upper and Lower GI Endoscopy - Lecture by Dr R K Mishra. Endoscopy is a procedure in which the gastro-intestinal tract is viewed through a lighted, flexible endoscope. Small samples of tissues cells (biopsy) can also be collected and sent for testing. There are two basic types of endoscopy. Upper endoscopy – The esophagus, stomach, and small intestines can be viewed by a thin flexible tube inserted through the mouth. Colonoscopy – The lining of the large intestine, colon and rectum can be viewed by a flexible tube inserted through the rectum. Preparation of the patient for endoscopy. Blood tests are sometimes required. Medications can be given by vein if needed. In case of upper GI endoscopy: No food or drink is allowed for six hours before the procedure. An empty stomach allows for the best view and safest exam. In case of Colonoscopy: Drink only clear liquids for at least 24 hours before the procedure. A laxative or special cleansing solution will be ordered by the physician to clear the bowel of stool so that the rectum/intestines can be seen.
How to Do Safe Upper and Lower GI Endoscopy – Lecture by Dr. R. K. Mishra at World Laparoscopy Hospital
Gastrointestinal endoscopy has become an essential diagnostic and therapeutic tool in modern medicine. Procedures such as upper GI endoscopy and lower GI endoscopy (colonoscopy) allow physicians to directly visualize the digestive tract, diagnose diseases early, and perform minimally invasive treatments. In a detailed educational lecture at World Laparoscopy Hospital, Dr. R. K. Mishra explained the principles, techniques, and safety measures required to perform safe and effective upper and lower GI endoscopy. His lecture emphasizes patient safety, proper technique, and systematic examination to minimize complications and improve diagnostic accuracy.
The first step in performing safe GI endoscopy is proper patient preparation. According to Dr. R. K. Mishra, careful patient selection and evaluation are critical. A detailed medical history must be taken to identify underlying conditions such as bleeding disorders, heart disease, or allergies to sedative medications. In upper GI endoscopy, patients are typically advised to fast for at least six hours before the procedure to ensure a clear view of the esophagus, stomach, and duodenum. For lower GI endoscopy, proper bowel preparation using laxatives is essential to cleanse the colon and allow accurate visualization of the intestinal lining.
During upper GI endoscopy, the endoscope is gently inserted through the mouth and advanced through the esophagus into the stomach and duodenum. The procedure requires patience, careful manipulation, and continuous visualization. Dr. R. K. Mishra highlights the importance of avoiding excessive force while advancing the endoscope, as this may cause injury to the mucosal lining or even perforation. The physician must carefully inspect anatomical landmarks such as the gastroesophageal junction, gastric body, pylorus, and duodenum. Any abnormalities like ulcers, inflammation, bleeding, or tumors should be documented and biopsied when necessary.
Lower GI endoscopy, commonly known as colonoscopy, involves examining the large intestine using a flexible colonoscope. The procedure begins with careful insertion of the scope through the rectum while maintaining proper insufflation and visualization. Dr. R. K. Mishra explains that maintaining correct scope orientation and minimizing looping are key technical skills for safe colonoscopy. The endoscopist must advance the instrument gradually through the rectum, sigmoid colon, descending colon, transverse colon, ascending colon, and finally reach the cecum. Adequate withdrawal time is equally important because many lesions, including polyps and early cancers, are detected during the withdrawal phase rather than insertion.
Safety during endoscopy also depends on proper monitoring and infection control. In his lecture at World Laparoscopy Hospital, Dr. R. K. Mishra stresses the importance of monitoring vital signs such as pulse, blood pressure, and oxygen saturation throughout the procedure. Endoscopy equipment must be thoroughly disinfected and sterilized according to international guidelines to prevent cross-infection. The use of personal protective equipment and strict adherence to sterilization protocols protects both the patient and healthcare staff.
Another important aspect discussed in the lecture is complication prevention and management. Although GI endoscopy is generally safe, potential complications include bleeding, perforation, infection, and adverse reactions to sedation. Early recognition of warning signs—such as severe abdominal pain, persistent bleeding, or sudden changes in vital signs—is essential. Prompt intervention and proper training help reduce the risk of serious outcomes.
The lecture by Dr. R. K. Mishra at World Laparoscopy Hospital highlights that mastering GI endoscopy requires both theoretical knowledge and practical experience. Surgeons and gastroenterologists must develop hand-eye coordination, understand gastrointestinal anatomy, and follow standardized protocols. Continuous training, simulation practice, and supervised procedures help medical professionals gain confidence and competence.
In conclusion, safe upper and lower GI endoscopy depends on proper patient preparation, gentle technique, careful visualization, strict infection control, and readiness to manage complications. The comprehensive lecture delivered by Dr. R. K. Mishra at World Laparoscopy Hospital provides valuable guidance for surgeons and trainees seeking to improve their endoscopic skills. By following these principles, healthcare professionals can ensure accurate diagnosis, effective treatment, and the highest level of patient safety in gastrointestinal endoscopic procedures.
