Gastroenterology is the branch of medicine which deals with the study of digestive system and diseases of the related organs. It involves detailed understanding of the physiology and functioning of the gastrointestinal organs. Diseases affecting gastrointestinal tract are the major focus of Gastroenterology. Hepatology is the study of liver, pancreas and biliary tract are considered as sub-specialty in this study.
Digestive system or Alimentary system:
The digestive system or alimentary system consists of accessory organs of digestion from mouth to anus along the alimentary canal and gastrointestinal tract. Digestive organs include esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts and liver. Digestive systems’ main function is digestion and absorption of food. The gastrointestinal tract is responsible for mechanical breakdown of food into small molecules that starts in mouth and continues into stomach and chemical digestion by enzymes helps to absorb the nutrients into the body which continues in the intestines.
Hepatology is the sub specialty in Gastroenterology which deals with the study, analysis, prevention and administration of ailments that influence Liver. Liver is the vital organ which plays a major role in metabolism. Liver is highly specialized and regulates a wide range of high volume biochemical reactions. Liver weighs about 1.44-1.66 kgs located at upper right quadrant of abdominal cavity and rests below diaphragm to the right of the stomach and overlies the gallbladder.
Liver diseases are also termed as hepatic disease. Most commonly found liver disease includes Hepatitis, Jaundice, Cirrhosis, Alcoholic Liver Disease, Non-Alcoholic Fatty Liver and Liver Abscesses. Liver disease rarely results in pain, portal hypertension and immunosuppression.
The esophagus also known as gullet which consists of muscular tube through which the food passes to stomach. The average length is 25 cm and varies with height. High amounts of food is passed over time in the esophagus and so it protected by a mucous membrane of epithelium and acts as a smooth surface.
Esophageal disorders are often associated with swallowing disorders where prolonged swallowing time is observed. Other disorders of Esophagus include Gastroesophageal Reflux normally called as Heartburn, Barrett’s Esophagus, Esophageal Cancer, Esophageal Motility Disorder and Esophageal Dysphagia which can prevent the food passage leading to difficulty in swallowing and can completely block the esophagus.
Stomach is a vital organ of the body which plays an important role in digestion. The stomach is a J shaped organ but it varies in size and connected to esophagus to its upper end and small intestine at its lower end. Gastric juice produced by the stomach plays an important role in digestion. To protect the stomach from the acid, mucus is produced which acts as a protective layer. Diseases of stomach are often caused by the infection of Helicobacter pylori such as Ulcers, Stomach Cancer and Gastritis.
The lower gastrointestinal tract consists of small intestine and large intestine. It starts with the sphincter of stomach and ends at the anus. The cecum imparts the small and large intestine. Most of the food digestion takes part in small intestine and in the large intestine the water is absorbed and the remaining waste is stored as feces before defecation.
Generally inflammation of intestines is found which leads to several disease conditions such as Enterocolitis, Inflammatory Bowel Disease and Intestinal Ischaemia.
Rectal and Anal diseases:
The rectum is the final straight portion of the large intestine and is followed by anal canal. Rectum acts as a temporary storage site for feces. The anal canal is the terminal part of the large intestine. In humans it is approximately 2.5 to 4 cm long.
Rectal and Anal diseases may be asymptomatic or may present with pain, a feeling of incomplete emptying or pencil thin stool and these diseases are commonly seen in elderly people.
The pancreas is a glandular organ in the digestive system. It is located in the abdominal cavity behind the stomach and produces many hormones as it is an endocrine gland. Pancreas secretes fluid that has enzymes, into the duodenum which helps in breakdown of carbohydrates, proteins and lipids.
There are a variety of disorders of the pancreas including Pancreatitis due to inflammation of pancreas, Hereditary Pancreatitis and Pancreatic cancer. Pancreatic diseases results in abdominal pain, vomiting and nausea.
The biliary system refers to liver, biliary tract and gall bladder. Bile is secreted by liver into small ducts that joins to form common hepatic duct. The secreted bile is stored in the gall bladder which is a small organ where the stored bile is concentrated before it is released it into small intestine. Bile helps in absorption of vitamin k from the diet. The hepatobiliary system affects the biliary tract to secrete bile in order to aid the digestion of fats.
Diseases of the biliary tract (gallbladder and bile ducts) are common and result in significant morbidity and mortality. Diseases such as Cholangitis and Cholecytitis are due to inflammation of bile duct and gall bladder respectively.
To undergo diagnosis for digestive disorders patient has to undergo an extensive diagnostic evaluation prior to which thorough and accurate medical history is taken and on studying the symptoms the affected individual may have to give lab tests and imaging tests.
Fecal Occult Blood Test: A fecal occult blood test looks for the hidden blood in the stool. A small amount of stool is placed on the card and checked.
Stool Culture: A small sample of stool is collected and checked for the presence of abnormal bacteria in the digestive tract which may cause diarrhea.
Renal Function Test: Patients with reduced kidney function or renal failure undergo kidney function tests prior to imaging tests. These tests include blood creatinine test and creatinine clearance tests, blood urea test, urinalysis, urea clearance test and eGFR (estimated glomerular filtration rate).
Barium Meal Test: The patient eats a meal containing barium his allows the radiologist to watch the stomach as it digests the meal. The amount of time it takes for the barium meal to be digested and leave the stomach gives the healthcare provider an idea of how well the stomach is working and helps to find emptying problems that may not show up on the liquid barium X-ray.
Colorectal Transit Study: This test shows how well food moves through the colon. The patient swallows capsules containing small markers which are visible on X-ray. The patient follows a high-fiber diet during the course of the test. The movement of the markers through the colon is monitored with abdominal X-rays taken several times 3 to 7 days after the capsule is swallowed.
Computed Tomography Scan (CT or CAT Scan): This is an imaging test that uses X-ray and a computer to make detailed images of the bones, muscles, fat and organs.
Defecography: Defecography is an X-ray of the anorectal area that evaluates completeness of stool elimination, identifies anorectalabnormalities, and evaluates rectal muscle contractions and relaxation.The patient's rectum is filled with a soft paste that is the same consistency as stool. The patient then sits on a toilet positioned inside an X-ray machine, and squeezes and relaxes the anus to expel the solution. The radiologist studies the X-rays to determine if anorectal problems happened while the patient was emptying the paste from the rectum.
Magnetic Resonance Imaging (MRI): MRI is a diagnostic test that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. The patient lies on a bed that moves into the cylindrical MRI machine. The machine takes a series of pictures inside of the body using a magnetic field and radio waves. The computer enhances the pictures produced.
Ultrasound: Ultrasound is a diagnostic imaging technique that uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs. Ultrasounds are used to view internal organs as they function, and to assess blood flow through various vessels. Gel is applied to the area of the body being studied, such as the abdomen, and a wand called a transducer is placed on the skin. The transducer sends sound waves into the body that bounce off organs and return to the ultrasound machine, producing an image on the monitor.
Colonoscopy: Colonoscopy helps to view the entire length of the large intestine (colon). It can often help identify abnormal growths, inflamed tissue, ulcers, and bleeding. It involves inserting a colonoscope, a long, flexible, lighted tube, in through the rectum up into the colon.
Endoscopic Retrograde Cholangio-Pancreatography (ERCP): ERCP is a procedure that allows diagnosing and treating problems in the liver, gallbladder, bile ducts, and pancreas. The procedure combines X-ray and the use of an endoscope. This is a long, flexible, lighted tube. The scope is guided through the patient's mouth and throat, then through the esophagus, stomach, and duodenum (the first part of the small intestine). The healthcare provider can examine the inside of these organs and detect any abnormalities. A tube is then passed through the scope, and a dye is injected that will allow the internal organs to appear on an X-ray.
Capsule Endoscopy: A capsule endoscopy helps to examine the small intestine. This procedure is helpful in identifying causes of bleeding, detecting polyps, inflammatory bowel disease, ulcers, and tumors of the small intestine. A sensor device is placed on a patient's abdomen and a PillCam is swallowed. The PillCam passes naturally through the digestive tract while transmitting video images to a data recorder. The data recorder is secured to a patient's waist by a belt for 8 hours. Images of the small bowel are downloaded onto a computer from the data recorder.
Esophageal pH Monitoring: An esophageal pH monitor measures the acidity inside of the esophagus. It is helpful in evaluating gastroesophageal reflux disease (GERD). A thin, plastic tube is placed into a nostril, guided down the throat, and then into the esophagus. The tube stops just above the lower esophageal sphincter. This is at the connection between the esophagus and the stomach. At the end of the tube inside the esophagus is a sensor that measures pH, or acidity. The other end of the tube outside the body is connected to a monitor that records the pH levels for a 24 to 48 hour period. Normal activity is encouraged during the study, and a diary is kept of symptoms experienced, or activity that might be suspicious for reflux, such as gagging or coughing, and any food intake by the patient. It is also recommended to keep a record of the time, type, and amount of food eaten. The pH readings are evaluated and compared to the patient's activity for that time period.
Fast Editorial Execution and Review Process (FEE-Review Process):
Research and Reports in Gastroenterology is participating in the Fast Editorial Execution and Review Process (FEE-Review Process) with an additional prepayment of $99 apart from the regular article processing fee. Fast Editorial Execution and Review Process is a special service for the article that enables it to get a faster response in the pre-review stage from the handling editor as well as a review from the reviewer. An author can get a faster response of pre-review maximum in 3 days since submission, and a review process by the reviewer maximum in 5 days, followed by revision/publication in 2 days. If the article gets notified for revision by the handling editor, then it will take another 5 days for external review by the previous reviewer or alternative reviewer.
Acceptance of manuscripts is driven entirely by handling editorial team considerations and independent peer-review, ensuring the highest standards are maintained no matter the route to regular peer-reviewed publication or a fast editorial review process. The handling editor and the article contributor are responsible for adhering to scientific standards. The article FEE-Review process of $99 will not be refunded even if the article is rejected or withdrawn for publication.
The corresponding author or institution/organization is responsible for making the manuscript FEE-Review Process payment. The additional FEE-Review Process payment covers the fast review processing and quick editorial decisions, and regular article publication covers the preparation in various formats for online publication, securing full-text inclusion in a number of permanent archives like HTML, XML, and PDF, and feeding to different indexing agencies.
