37
What is the causes, management, symptoms of Haemorrhoids
SYMPTOMS • May have a change in bowel habits ie constipation preceding this • Uncomplicated haemorrhoids: Painless bleeding after defecation • May streak faeces or on the toilet paper • If copious it may splash into toilet bowel or cause iron deficiency anemia • Palpable lump • Sensation of prolapse after defecation • May cause perianal discomfort & discharge which can lead to pruritis CAUSES • Straining • Cirrhosis leading to portal caval anastomoses • Pregnancy MANAGEMENT • PR exam • Involves inserting a gloved finger with lubricant into the anus to look for any abnormalities such as ulceration, lumps, fissures, prostate • Gastro referral for colonoscopy (due to change in bowel habits, ? family history)
38
Differential diagnosis' for malaena
* Peptic Ulcer * Oesophageal cancer * Gastric cancer * Oesophageal varices

weight loss, anorexia, night sweats + dull aching abdominal pain
41
What other symptoms would you expect to see in Crohn's VERSUS UC
Crohn’s disease (diarrhoea, RLQ abdo pain), UC (mucous, blood)
42
What are some prehepatic causes of jaundice?
Unconjugated hyperbilirubinemia – light urine, pale stools Can develop kernicterus (brain damage) if unconjugated bilirubin crosses the BBB (toxic) • Haemolysis (decreased haptoglobin) - -->Intrinsic: RBC defects – spherocytosis, thalassemia, sickle cell anemia - -->Extrinsic: Mechanical (prosthetic valves, marching), immune
43
What are some hepatic causes of jaundice
May be conjugated or unconjugated hyperbilirubinemia depending on cause • Congenital – impaired conjugation o Lack of mature hepatic enzymes at birth o Genetic deficiency (Crigler Najjar Syndrome) o Gilbert’s Syndrome (AD, decreased UGT1A1 activity) • Traumatic – massive trauma • Infective – viral (EBV, CMV, hep A, B, C), bacterial (any), protozoa (malaria), fungi (candida) • Inflammatory – NASH, Primary Biliary Cirrhosis • Neoplastic – obstructive • Metabolic – glycogen storage disease • Endocrine – diabetes mellitus • Toxic – ETOH, CaCl- • Idiopathic
44
What are some post hepatic causes of jaundice
Conjugated hyperbilirubinemia, dark urine + pale stools + pruritis • Biliary Tree o Lymph node enlargement – mets/lymphoma o Post surgical strictures o Gallstones or parasite blockage – worms! • Pancreas: Head of pancreas tumour (painless jaundice + enlarged non-tender gallbladder)
45
In someone with abdominal distension, what clinical signs would you look for to determine if SBO or LBO?
o SBO = vomiting, distension, pain → Adhesions, hernia o LBO = constipation +- pain → Volvulus, cancer
46
INVESTIGATING GI SYMPTOMS | - what would you do in EXAMINATION?
Vital signs: Temperature, RR, pulse & BP Abdominal palpation & examination ->Guarding, rigidity (ruptured PUD) Resp – listen to lungs Cardio – chest sounds, ?ECG
47
INVESTIGATING GI SYMPTOMS | - what would you do in IMAGING?
Erect CXR – pneumoperitoneum, heart & lung pathology Abdominal USS ->Gallstones: in GB, dilated CBD in cholangitis, thickened gallbladder walls in cholecystitis - >AAA, pancreas (oedema), appendix, kidneys (inflammation), ovaries CT scan – gold standard for PANCREATITIS, contrast CT can help identify diverticulitis Abdominal Xray – signs of Crohn’s or UC, volvulus or bowel obstruction -> Bowel obstruction → Erect abdominal X-ray – air/fluid levels (>3), distended bowel loops (>3, 6, 9 cm) Colonoscopy – looking for polyps (can biopsy), bleeding in diverticular disease
48
INVESTIGATING GI SYMPTOMS | - what would you do in LAB INVESTIGATIONS?
FBC – WCC for inflammation/infection, Hb for blood loss LFTs – liver enzymes & bilirubin, albumin UECs – surgical & medication purposes + if vomiting/dehydrated, kidney function Lipase – pancreatitis Urine MSU & MCS Beta-hCG if considering ectopic pregnancy
49
What are the TWO MANAGEMENT options for biliary pathology
1. ERCP | 2. Laparoscopic Cholecystectomy
50
Explain an ERCP to a patiient
* Used in choledocolithiasis, cholangitis & gallstone pancreatitis * Remove stone using ERCP (endoscopic retrograde cholioangiopancreatography) – pass tube through stomach & through the sphincter of oddi into CBD & remove stone (may need a sphincterotomy or to dilate the sphincter with a balloon). If the stone cannot be removed may just put in a stent
51
Explain a lap choley to a patient
* Most cholecystectomy’s are done laparoscopically & are often done as inpatients without the need for an overnight stay in hospital. They usually take about 2 hours in uncomplicated cases. * The surgeon inflates stomach with air or CO2 to see clearly, then inserts a lighted scope attached to a video camera (laparoscope) into an incision near the belly button & uses this as a guide while inserting surgical instruments into other incisions to remove your GB. * Usually you will have 4 incisions; one at the navel, one epigastric, mid clavicular (under rib), and anterior axillary. * Lap cholecystectomy’s do not require the abdominal muscles to be cut, resulting in less pain, quicker healing & improved cosmetic results & fewer complications such as infection & adhesions. * Indicated for patients with symptoms deemed to be due to gallstones & asymptomatic patients with gallbladder stones who are at risk of complications - diabetics, porcelain gallbladder (15-20% a/w carcinoma), history of pancreatitis, long-term immunosuppression. * Risks: conversion to open operation (5-10%, usually secondary to unexpected inflammation, scar tissue, injury or bleedig), bile duct injury (<1%), bleeding (2%), bile leak (1%), risks of general anaesthesia. * Because they have removed the GB, you can no longer store bile between meals – in most people this has little or no effect on digestion
