    Study Notes

    Radiography and Gastrointestinal Disorders Summary

    • Closed loop obstruction can result from volvulus or adynamic ileus, causing uniformly dilated intestines that resolve within 36 to 48 hours.
    • Sigmoid volvulus involves the sigmoid colon twisting on itself, forming an inverted "U" shape and losing its normal haustral markings, leading to a sausage or balloon-like appearance.
    • Cecal volvulus involves the cecum twisting around its mesentery, becoming distended and shifting up and to the left within the abdomen.
    • Pneumoperitoneum, with air or gas in the peritoneal cavity, can be revealed by an upright chest radiograph.
    • Barium enema for evaluating the colon involves a low residue diet, clear fluid diet, laxative colonic lavage if necessary, and specific positions for tube insertion.
    • Different radiographic projections and positions are used to demonstrate specific aspects of the colon, such as the right colic flexure, ascending colon, left colic flexure, and other areas.
    • Various gastrointestinal disorders, including Crohn's disease, ulcerative colitis, malabsorption syndrome, diverticular disease, Meckel's diverticulum, intussusception, and different types of polyps, are discussed.
    • Predisposing factors for colon cancer include ulcerative colitis, familial polyposis, and genetic factors, with 75% of cases occurring in the recto-sigmoid region.
    • Peritonitis, Hirschsprung's disease, and imperforate anus are mentioned as other gastrointestinal conditions.
    • Cholecystography, cholangiogram, choleography, cholecystocholangiogram, percutaneous transhepatic cholangiography, laparoscopic cholecystectomy, operative cholangiography, T-tube cholangiography, and endoscopic retrograde cholangiopancreatography are described as diagnostic and treatment procedures for gallbladder and biliary disorders.
    • Pancreatitis, cholecystitis/cholelithiasis, cirrhosis of the liver, and hepatocellular carcinoma are detailed as liver and pancreatic disorders.
    • The text also mentions the most common type of pancreatic cancer, pancreatic ductal adenocarcinoma, and its origin in the pancreatic ducts.
