A 22-year-old male presented with confusion and jaundice. Laboratory results showed abnormal liver function tests and coagulopathy consistent with acute liver failure (ALF). The differential diagnosis for ALF includes drug toxicity, viral hepatitis, and other conditions. The most likely cause in this patient is isoniazid toxicity from his recent tuberculosis treatment, as 1-2% of patients can develop severe liver injury from isoniazid. Management involves supportive care, investigating the underlying cause, and consideration of liver transplantation if criteria are met.

This PPT presentation is Image Based Questions of Hepato-Biliary-Pancreatic pathologies. This is useful as self-assessment and review of the subject. This is also useful for USMLE and NEET exams
This 47-year-old male presented with abdominal pain and fever and was found to have a contained perforated duodenal ulcer. He had a history of diabetes, hypertension, cholecystectomy, and pancreatitis. Imaging revealed distention of the left colon, air fluid levels, and stranding around the pancreas. He underwent laparotomy which showed a contained anterior duodenal ulcer perforation resulting in a large left subphrenic abscess. The abscess was drained and the perforated ulcer was sutured. Diabetics are at higher risk for complications of peptic ulcer disease such as perforation due to reduced pain sensitivity.
This document contains 30 multiple choice questions related to gastrointestinal disorders. The questions cover topics like upper GI bleeding, peptic ulcer disease, inflammatory bowel disease, diverticulitis, hemorrhoids, and anorectal disorders. Each question is followed by 5 possible answer choices, with the correct answer listed at the end in bold. This assessment tests knowledge of the clinical presentations, diagnostic tools, treatments, and complications associated with various GI conditions.
1) A 65-year-old man presented with spontaneous hemoperitoneum and required multiple surgeries including small bowel resection.
2) He developed complications including an ileus, myocardial infarction, and anastomotic leak, preventing enteral nutrition.
3) After 11 days without adequate nutrition, the patient was started on total parenteral nutrition (TPN) which was advanced cautiously due to his risk for refeeding syndrome.
4) TPN met his nutritional needs and supported wound healing and recovery.
The document describes the rules and proceedings of a gastroenterology quiz being conducted. It provides details of the different rounds in the quiz - a passing round with direct questions, a second round requiring logical thinking, a third round being a flag round, and a final rapid fire round. It then presents the questions asked in each round, along with the answers provided by the participating teams within the given time limits. The rounds assess the teams' knowledge of topics like diseases, investigations, anatomy and complications related to gastroenterology.
Laparoscopic cholecystectomy is considered the most cost-effective treatment for symptomatic gallstones. It has advantages over open cholecystectomy such as less postoperative pain, shorter hospital stays, and faster recovery times. While watchful waiting can be adopted for asymptomatic gallstones, symptomatic patients with biliary pain or complications like acute cholecystitis or gallstone pancreatitis generally require early cholecystectomy to alleviate symptoms and reduce risks. Ultrasound is the initial test to diagnose gallstones but HIDA scans may help diagnose biliary dyskinesia when gallstones are not found.
Acute appendicitis and Acute Abdominal Painchaliter
The document discusses a case of a 9-year-old female diagnosed with acute appendicitis. It provides background on appendicitis including that it is the most common acute surgical condition in children, with a peak incidence between ages 10-18. The patient presented with 8 days of hypogastric pain and intermittent fever. Exams showed guarding and tenderness, and tests confirmed leukocytosis. She underwent an emergency appendectomy, was treated with antibiotics, and recovered well.
Necrotizing enterocolitis (NEC) is a devastating disease that primarily affects premature infants. It was first described in the 1960s but the incidence and associated mortality have not changed significantly despite advances in neonatal care. NEC can cause pneumatosis intestinalis, portal venous gas, intestinal perforation, and systemic complications. It remains difficult to prevent and treat. Differential diagnoses include conditions seen in term infants associated with drug use or anomalies, and spontaneous intestinal perforations seen in very preterm infants without feeding. NEC costs over $500 million annually in the US due to increased hospitalization time and risk of short bowel syndrome requiring long-term care.
This document discusses functional constipation. It provides the Rome IV diagnostic criteria for functional constipation which includes symptoms like straining, hard stools, sensation of incomplete evacuation occurring in over 25% of bowel movements. It notes that loose stools are rarely present without laxative use. Therapeutic options for functional constipation are discussed including fiber, PEG, linaclotide, prucalopride, and lubiprostone. A diagnostic and therapeutic algorithm is proposed. Risk factors for anorectal pathology after pregnancy are also discussed.
This document discusses obscure gastrointestinal bleeding (OGIB), which constitutes about 5% of GI bleeding cases and can have significant morbidity and mortality. OGIB is bleeding of unknown origin after an initial negative endoscopic evaluation. It may present as recurrent iron deficiency anemia, fecal occult blood tests, melena, or hematochezia. Evaluation tools include video capsule endoscopy (VCE), push enteroscopy, double balloon enteroscopy, single balloon enteroscopy, intra-operative enteroscopy, and imaging. VCE has a high sensitivity of 89-92% and specificity of 95% for detecting small bowel lesions that may have been missed on previous endoscopies. Common VCE findings in cases of OGIB
An 85-year-old man presented with 5 days of abdominal pain and worsening mental status. On exam, he had a suprapubic mass. Labs showed elevated creatinine. A renal ultrasound found right hydronephrosis. Inserting a Foley catheter drained 2500cc of urine and resolved the mass. He was diagnosed with urinary retention from an enlarged prostate and treated with catheterization, hydration, and medications for his prostate and urinary symptoms.
A 48-year-old Bangladeshi man presented with abdominal pain and vomiting. Laboratory tests found eosinophilia. Imaging showed distal ileal inflammation. Endoscopy revealed eosinophilic gastroenteritis, a condition where the stomach and intestines become inflamed due to an abnormal buildup of white blood cells called eosinophils. The patient was treated with an empirical regimen for gastroenteritis and parasites, but did not improve, leading to the endoscopy diagnosis of eosinophilic gastroenteritis.
The document summarizes key points about the diagnosis and management of GERD. It finds that the prevalence of GERD is 10-20% in Western countries and less than 5% in Asia. A therapeutic trial using a high-dose PPI is the standard initial approach to diagnosis. Lifestyle modifications like weight loss and elevating the head of the bed can help symptoms. Endoscopy is recommended when symptoms persist despite PPI treatment or if there are alarm features to rule out complications. The take home message is that GERD diagnosis is typically symptom-based initially with a PPI trial, while endoscopy is used when necessary to investigate atypical symptoms or risk factors for Barrett's esophagus.
This document contains 47 multiple choice questions related to gastroenterology and the liver. The questions cover topics such as the classification of different types of jaundice, hepatitis viruses, investigations for liver diseases, complications of cirrhosis such as portal hypertension and ascites, and treatment of conditions like hepatic encephalopathy and spontaneous bacterial peritonitis.

Neonatal necrotizing enterocolitis
NEC is the most common life-threatening emergency of the gastrointestinal tract in the newborn period. The disease is characterized by various degrees of mucosal or transmural necrosis of the intestine. The cause of NEC remains unclear but is most likely multifactorial. The incidence of NEC is 1-5% of infants in neonatal intensive care units (NICUs). Both incidence and case fatality rates increase with decreasing birthweight and gestational age. Because very small, ill preterm infants are particularly susceptible to NEC, a rising incidence may reflect improved survival of this high-risk group of patients.
Clinical Manifestations
Infants with NEC have a variety of signs and symptoms and may have an insidious or sudden catastrophic onset (Table 96-1). The onset of NEC is usually in the 2nd or 3rd week of life but can be as late as 3 mo in VLBW infants. Age of onset is inversely related to gestational age. The 1st signs of impending disease may be nonspecific, including lethargy and temperature instability, or related to gastrointestinal pathology, such as abdominal distention and gastric retention. Obvious bloody stools are seen in 25% of patients. Because of nonspecific signs, sepsis may be suspected before NEC. The spectrum of illness is broad, ranging from mild disease with only guaiac-positive stools to severe illness with bowel perforation, peritonitis, systemic inflammatory response syndrome, shock, and death. Progression may be rapid, but it is unusual for the disease to progress from mild to severe after 72 hr.
Diagnosis
A very high index of suspicion in treating preterm at-risk infants is crucial. Plain abdominal radiographs are essential to make a diagnosis of NEC. The finding of pneumatosis intestinalis (air in the bowel wall) confirms the clinical suspicion of NEC and is diagnostic; 50-75% of patients have pneumatosis when treatment is started (Fig. 96-4). Portal venous gas is a sign of severe disease, and pneumoperitoneum indicates a perforation (Figs. 96-4 and 96-5). Hepatic ultrasonography may detect portal venous gas despite normal abdominal roentgenograms .
This document summarizes the diagnosis, etiology, management, and treatment of acute pancreatitis based on guidelines from the American College of Gastroenterology. It presents a case study of a 47-year-old female diagnosed with gallstone pancreatitis based on abdominal pain, elevated lipase, and ultrasound findings of cholelithiasis. Her case is used to illustrate the guidelines, including IV fluid hydration, no antibiotics given due to mild symptoms resolving in 48 hours, and cholecystectomy before discharge due to gallstone etiology.
The document discusses a case of acute abdominal pain in a 24-year-old male. It provides details of the patient's history, physical exam findings, and differential diagnosis. The document then reviews approaches to evaluating abdominal pain, including types of pain, history taking, physical exam maneuvers, potential diagnoses, appropriate tests, and disposition planning.
A 19-year-old female presented with dysphagia and odynophagia for a few days without weight loss or other symptoms. Examination found normal vital signs and no other abnormalities. Endoscopy initially showed an upper esophageal lesion of unclear etiology. Narrow band imaging revealed the lesion to be inflammatory and ulcerative rather than cancerous. Further history revealed the patient was taking tetracycline with only sips of water while lying down, confirming the diagnosis of pill esophagitis. No local endotherapy was needed at this time unless a benign stricture develops.
This case presentation discusses a 47-year old male patient who was referred for abdominal pain, nausea, vomiting and significant weight loss. Investigations revealed jejunization of the ileum on CT scan and villous atrophy on biopsy. The patient was initially treated for Crohn's disease but did not improve. Further histopathology found a thick collagenous band suggestive of collagenous sprue. The patient was started on a gluten-free diet, steroids, total parenteral nutrition, and anti-TNF therapy, leading to improved symptoms. Collagenous sprue is a rare malabsorptive disorder characterized by villous atrophy and thick subepithelial collagen deposits. Treatment is challenging but may include steroids
A 17-year-old boy presented with 6 weeks of abdominal pain and unintended weight loss. Imaging showed irregular narrowing in the cecum and peritoneal implants throughout the abdomen. During his hospitalization, the patient developed a fever and CT scans showed a mediastinal mass and multiple lung nodules. Biopsies of the mediastinal mass and peritoneal implants were performed to determine the cause of the patient's symptoms and abnormal imaging findings.

The correct answers are not provided.
The patient is a 45-year-old female presenting with sudden abdominal pain for 3 hours in her epigastric and right upper quadrant areas. She reports one episode of vomiting and a subjective fever. Her vital signs show elevated blood pressure, heart rate, and temperature. Physical exam reveals tenderness in the epigastric and right upper quadrants. Based on her history and exam findings, she is suspected to have acute cholecystitis.
Case presentation on AUTOIMMUNE HEP final.pptxZairaHussain6
This document describes a case of an 11-year-old female child presenting with abdominal distension and blood in stool. Various tests were performed and findings were consistent with cirrhosis of the liver with portal hypertension. Further workup revealed positive ANA and ASMA antibodies, consistent with a diagnosis of autoimmune hepatitis. Autoimmune hepatitis is a chronic disease of unknown cause characterized by liver inflammation and necrosis that can progress to cirrhosis. It has two main types and is diagnosed based on elevated enzymes, antibodies, and histopathology. Treatment involves immunosuppression with steroids and medications, with the goal of achieving remission though relapse is common.
1. Diarrhea is defined as an increased frequency, fluidity, and volume of stool. It can be acute (<14 days), persistent (14-30 days), or chronic (>30 days).
2. The document discusses the pathophysiology, etiology, indications for referral to a gastroenterologist, initial evaluation, and recommendations for evaluating patients with chronic diarrhea.
3. The differential diagnosis and workup of inflammatory bowel diseases like Crohn's disease and ulcerative colitis are outlined, including relevant history, physical exam findings, diagnostic studies, endoscopy, histopathology, and radiology findings.
This document contains multiple questions about diagnosis and management of gastrointestinal conditions. Question 14 describes a case of a young Hispanic man with early satiety and weight loss found to have extensive thickening of the stomach wall and signet ring cell adenocarcinoma. His two brothers also had early-onset gastric cancer. The underlying genetic defect in this family is a CDH1 gene mutation which causes hereditary diffuse gastric cancer. Question 15 describes a woman with hepatitis C, anemia, and melena found to have findings in her stomach antrum. Biopsy revealed reactive gastropathy and dilated capillaries containing fibrin thrombi. The most appropriate management is proton pump inhibitor therapy.
This document discusses primary biliary cirrhosis (PBC), a chronic disease that slowly destroys bile ducts in the liver. It begins by describing a 45-year-old patient presenting with fatigue, itching, jaundice, and an enlarged spleen. Test results and liver biopsy are needed to diagnose PBC, which is characterized by antibodies and inflammation of bile ducts. Ursodeoxycholic acid is the standard treatment and improves liver tests, though transplantation may be needed for advanced cases.

Case-Based Approach To Crohn’s Disease.pptxMohamed Wifi
Mona, a 22-year-old girl, presented with a 6-week history of non-bloody diarrhea and abdominal pain. Tests revealed anemia, elevated inflammatory markers, and red blood cells in her stool. Colonoscopy showed inflammation consistent with Crohn's disease. Her Crohn's disease activity index score was 377, indicating severe disease. Guidelines recommend induction therapy with corticosteroids for moderate-to-severe Crohn's, or biologics for cases refractory to other treatments. Ongoing management involves assessing disease severity, selecting targeted therapies, and achieving mucosal healing to prevent complications.
Inflammatory Bowel Disease Case Study The patien.docxcarliotwaycave
Inflammatory Bowel Disease
Case Study
The patient is an 11-year-old girl who has been complaining of intermittent right lower
quadrant pain and diarrhea for the past year. She is small for her age. Her physical
examination indicates some mild right lower quadrant tenderness and fullness.
Studies Results
Hemoglobin (Hgb), 8.6 g/dL (normal: >12 g/dL)
Hematocrit (Hct), 28% (normal: 31%-43%)
Vitamin B12 level, 68 pg/mL (normal: 100-700 pg/mL)
Meckel scan, No evidence of Meckel diverticulum
D-Xylose absorption, 60 min: 8 mg/dL (normal: >15-20 mg/dL)
120 min: 6 mg/dL (normal: >20 mg/dL)
Lactose tolerance, No change in glucose level (normal: >20 mg/dL rise in
glucose)
Small bowel series, Constriction of multiple segments of the small intestine
Diagnostic Analysis
The child's small bowel series is compatible with Crohn disease of the small intestine.
Intestinal absorption is diminished, as indicated by the abnormal D-xylose and lactose
tolerance tests. Absorption is so bad that she cannot absorb vitamin B12. As a result, she has
vitamin B12 deficiency anemia. She was placed on an aggressive immunosuppressive
regimen, and her condition improved significantly. Unfortunately, 2 years later she
experienced unremitting obstructive symptoms and required surgery. One year after surgery,
her gastrointestinal function was normal, and her anemia had resolved. Her growth status
matched her age group. Her absorption tests were normal, as were her B12 levels. Her
immunosuppressive drugs were discontinued, and she is doing well.
Critical Thinking Questions
1. Why was this patient placed on immunosuppressive therapy?
2. Why was the Meckel scan ordered for this patient?
3. What are the clinical differences and treatment options for Ulcerative Colitis and Crohn’s
Disease? (always on boards)
4. What is prognosis for patients with IBD and what are the follow up recommendations for
managing disease?

The document provides an overview of esophageal disorders, including their symptoms, diagnosis, and management. Key points include:
- Dysphagia can be caused by obstructive lesions like cancer/strictures or motility disorders. Diagnosis involves barium swallow, endoscopy, and manometry.
- Odynophagia can be due to conditions like GERD, infections, pill esophagitis, or radiation esophagitis.
- Barrett's esophagus develops in some with longstanding GERD and requires surveillance due to cancer risk.
- H. pylori testing is recommended if treating, for persistent dyspepsia, or lymphoma risk. Endoscopy is considered
cholecystitis and other gall bladder disorders 1.pdfAmanyireDickson1
The document presents a case of a 38-year-old female presenting with abdominal pain and is assessed for acute cholecystitis. It outlines the anatomy, epidemiology, clinical features, diagnosis and treatment of acute cholecystitis. The diagnosis of acute cholecystitis is considered based on the patient's history, physical exam findings, and diagnostic imaging and lab tests showing signs of gallbladder inflammation.
Acute biliary pancreatitis is caused by gallstones obstructing the common bile duct, which causes bile to reflux into the pancreas and induce inflammation. ERCP with sphincterotomy can effectively treat the obstruction but may benefit only patients with severe disease. While same-admission cholecystectomy is recommended after ERCP/sphincterotomy, further studies are needed to determine the optimal timing of cholecystectomy for mild versus severe cases of acute biliary pancreatitis.
Gastrointestinal bleeding can occur in the upper or lower GI tract. The most common causes of upper GI bleeding are peptic ulcer disease and esophageal/gastric varices, while hemorrhoids and diverticulosis are leading causes of lower GI bleeding. Colonoscopy is both diagnostic and therapeutic for GI bleeding and more accurate than other tests. Treatment involves fluid resuscitation, stopping ulcer-causing agents, acid suppression with PPIs, and antibiotics if H. pylori is detected to prevent ulcer recurrence.

The patient presented with symptoms of intestinal obstruction including abdominal pain, nausea, vomiting and abdominal distension. Physical exam revealed abdominal tenderness and laboratory tests showed signs of dehydration and inflammation. Radiographic imaging confirmed multiple dilated loops of small bowel consistent with mechanical intestinal obstruction. The obstruction was determined to be complete based on symptoms. The patient's history of previous appendectomy suggested the underlying cause was likely adhesive obstruction. Treatment involved fluid resuscitation, gastrointestinal decompression and antibiotics, with potential for surgical lysis of adhesions if symptoms did not improve.

Viral hepatitis can be acute or chronic depending on whether symptoms last less than or more than six months. The main causes are infectious hepatitis viruses like hepatitis A, B, C, D, and E. Hepatitis A spreads through the fecal-oral route while hepatitis B, C, and D spread through blood and body fluids. Many people infected with hepatitis B or C do not show symptoms but can develop chronic liver disease and cancer over time. Vaccines exist for hepatitis A and B but not for C, D, and E. Treatment focuses on managing symptoms for acute cases and antiviral drugs for chronic cases.
Infective Hepatitis can be acute or chronic depending on duration. Acute hepatitis may resolve on its own or progress to chronic hepatitis or rarely acute liver failure. Chronic hepatitis can progress to cirrhosis, liver failure, or cancer. Hepatitis is commonly caused by viral infections including hepatitis A, B, C, D, and E. Hepatitis A spreads through the fecal-oral route while hepatitis B, C, and D spread through blood and bodily fluids. Symptoms vary but often include fatigue, jaundice, abdominal pain, and nausea. Treatment depends on the type of hepatitis.

B) Creon (Correct)
C) Metronidazole
D) Octreotide
E) Praziquantel
5. Q 11
Answer feedback;
Correct answer – B
The x-ray shows calcification in the area of the pancreas, which would support a
diagnosis of diarrhoea secondary to chronic pancreatitis with pancreatic insufficiency.
Hence, the most suitable treatment is CREON, pancreatic enzymes which prevent the
malabsorption associated with pancreatic insufficiency.
Co-amoxiclav therapy would be useful for treating bacterial overgrowth. Metronidazole
can use for the treatment of pseudomembranous colitis caused by Clostridium difficile.
Octreotide (a long-acting synthetic somatostatin analogue) can use in the treatment of
carcinoid syndrome which may present with secretory diarrhoea (in about 83% of
cases).
Praziquantel is the treatment of choice for schistosomiasis. Continuing infection with
Schistosoma may cause granulomatous reactions and fibrosis in the affected organs,
which may result in many clinical manifestations.

B) Irritable bowel syndrome

8. Q 12
Answer feedback;
Correct answer – A
Distal intestinal obstruction syndrome occurs in 10-20% of patients with cystic
fibrosis and incidence increases with age, where about 80% of cases present for
the first time in adults. The pathogenesis is partially due to loss of CFTR function
in the intestine which results in deregulation of chloride secretion from the
crypts, bicarbonate secretion from Brunner's glands and sodium transport, which
leads to the accumulation of viscous mucus and faecal material in the terminal
ileum, caecum and ascending colon. The investigation should include a plain
abdominal radiograph which classically shows faecal loading in the right iliac
fossa, dilatation of the ileum and an empty distal colon. Ultrasound may help
identify an obstructive mass but cannot be relied upon to exclude other causes of
pain and bowel obstruction. However, CT can help with diagnosis and shows
dilated small bowel and proximal colon with or without intestinal wall swelling.
9. Q 12
Answer feedback;
Correct answer – A
Treatment for mild and moderate episodes is initially with hydration and full dietetic
review to ensure that the pancreatic enzyme dose correctly titrated to fat intake. As
a part of treatment, regular laxatives should be given, for example, senna and
lactulose. In addition, N-acetylcysteine can use in moderate episodes which loosens
and softens the plugs, presumably by 'opening' the disulphide bonds in the
abnormal intestinal mucus and maintains luminal patency. Severe episodes can treat
with gastrografin or with regularly Klean-Prep enema. If there are signs of peritoneal
irritation or complete bowel obstruction, a surgical review should take. Surgeons will
often treat initially with intravenous fluids and an NG tube while keeping the patient
nil by mouth. In that case, N-acetylcysteine can insert through the NG tube. In
resistant cases, phosphate or gastrograffin enemas can use, or colonoscopy with the
installation of gastrografin.
10. Q 13
An 88-year-old gentleman has brought to the A & E with a 12-hour history of
abdominal pain of sudden onset. On examination, he was pale, cold and clammy. At
that time his pulse was 110bpm and irregular along with blood pressure of 95/64
mmHg. Further, the abdomen was soft and mildly tender; bowel sounds were
absent. The patient's son has mentioned that his father has had three episodes of
passing plum coloured motions during the day. As a part of the diagnosis procedure,
arterial blood gas analysis was performed, which revealed the pH of 7.18 and base
deficit of -16.
Based on the above clinical scenario, what is the most likely diagnosis?
A) Acute pancreatitis
B) Ischaemic bowel
C) Pseudomembranous colitis
D) Ruptured abdominal aortic aneurysm

D) Ruptured abdominal aortic aneurysm
E) Sigmoid volvulus
12. Q 13
Answer feedback;
Correct answer – B
Above clinical scenario is fitting with ischaemic bowel disease, also known as mesenteric
infarction. As we all aware, there are three main blood vessels to supply the gut.
Although any the branches (coeliac, superior and the inferior mesenteric vessels) may
occlude, occlusion of the superior mesenteric artery is more common than the other two.
Though collateral vessels are there to SMA, they may not be able to dilate sufficiently
and quickly to overcome the acute occlusion. The occlusion may be due to a thrombus, or
an embolus which is common in elderly patients who are mainly in atrial fibrillation.
Dissecting aneurysm and vasculitis are other rare causes of infarction. The clinical
features include persistent, severe and generalised abdominal pain. Characteristically, the
pain is out of proportion. Sudden severe pain accompanied by a forceful intestinal
evacuation strongly suggests an acute arterial occlusion.
13. Q 13
Answer feedback;
Correct answer – B
The ischaemic bowel may shed the non-viable mucosa, which mixed with mucus
results in the appearance of plum coloured stools.
The inflammatory markers may elevate, and the blood gas may reveal a metabolic
acidosis like in the above case.
This condition is a surgical emergency as the patient rapidly becomes toxic and may
die from septic shock unless removing the infarcted bowel. Patients those who are
unfit for surgery must be managed with supportive measures such as resting the gut,
intravenous fluids and antibiotics, and monitoring of vital signs in a high dependency
unit.
Unfortunately, the outcome is not that satisfactory in conservative management
without surgical intervention.

The clinical picture of the patient mentioned above is going with the
diagnosis of acute mesenteric ischaemia most probably as a result of an
embolic occlusion of the superior mesenteric artery as a complication of
atrial fibrillation that has not diagnosed previously.
17. Q 15
An older man around 60 years of age has presented to gastroenterology clinic with a six-
month history of a burning type central chest discomfort, frequently occurred at night and
was associated with an acidic taste in the mouth.
He has had some relief by taking over-the-counter antacid tablets and had seen his GP
who prescribed a two-month course of omeprazole.
However, the patient has been still getting the symptoms.
His GP had also sent blood for Helicobacter pylori serology which was found to be
negative.
He was otherwise well and did not give a history of any weight loss, vomiting or dysphagia.
There was no other past medical history noted.
On examination, he looked well, not clinically anaemic; pulse was 80bpm and regular
along with a blood pressure of 135/70 mmHg.
His heart sounds were normal, and the chest was clear.
His abdomen was soft and non-tender with no palpable organomegaly or masses. A rectal
examination was unremarkable and normal stool was noted on the examination glove.
An outpatient upper gastrointestinal endoscopy revealed a 10 cm area of non-inflamed
Barrett's epithelium at the lower oesophagus; & multiple biopsies has taken.
The histology came as columnar-lined mucosa with intestinal metaplasia, and dysplasia
was not there.

20. Q 15
Answer feedback;
Correct answer – C
Unfortunately, Barrett's oesophagus is a serious complication of GERD. Anyhow, about
10% of people with chronic symptoms of GERD develop Barrett's oesophagus. Please note,
the risks of adenocarcinoma are relatively high (30 × normal), yet the absolute risk is low
as 1% per year to develop adenocarcinoma. This patient has no dysplasia and so at
present, we would start a PPI and re-scope in two years. This management is appropriate
in an otherwise healthy person; the merits of surveillance need to assess on a patient to
patient basis. However, low-grade dysplasia needs six monthly endoscopies & biopsy. On
the other hand, high-grade dysplasia needs further intervention; radiofrequency ablation
(RFA), photodynamic therapy (PDT), cryotherapy, endoscopic mucosal resection (EMR) or
oesophagectomy.
