Define GORD How does GORD present?
Gastroesophageal reflux disease is the retrograde flow of gastric contents through an incompetent gastroesophageal junction Presentation: 1) !! Heartburn: Burning retrosternal or epigastric pain which worsens on bending, stooping!!!, lying or hot drinks 2) Water brash 3) Acid reflux 4) Nausea/vomiting 5) Nocturnal cough or wheeze 6) Recurrent chest infections
26
GORD and dyspepsia typically have normal examination. When asked in an exam to perform a focused examination on anything GI, what should you always check for?
Abdominal massess Sx of anaemia Epigastric mass/tenderness Hepatomegaly Lymph nodes in neck (most imp supraclavicular left -> Virchow's)
27
Define Waterbrash
Mouth filling with saliva (like when someone is going to throw up)
28
Why would a patient with GORD present with a cough or wheeze?
Aspiration of stomach acid at night (when lying flat) => recurrent chest infections
29
Give 5 RF for GORD
1) Environmental (Smoking, alcohol) 2) Diet (Coffee, fatty food, big meals) 3) Obesity 4) Hiatus Hernia 5) Pregnancy 6) Drugs: NSAIDs, SSRI, anticholinergics, TCA 7) Tight clothes
30
Define Hiatus Hernia There are 2 types of hiatus hernia. What are they? What is the main RF?
Hiatus hernia is the herniation of the proximal stomach through the diaphragmatic hiatus into the thorax. There are 2 types: 1) 80% Sliding Hernia: The Gastroesophageal junction slides into thorax 2) 20% Rolling Hernia: Bulge of stomach herniates into thorax but Gastroesophageal junction remains in abdomen Obesity is the main rf (a/w tight clothes, fatty food...)
31
List 5 complications of GORD
1) Oesophagitis 2) Oesophageal stricture 3) Barret's oesophagus 4) Oesophageal haemorrhage 5) Anaemia
32
What is another term for Gastro-oesophageal junction? (From a histologists POV)
Squamocolumnar junction
33
Define Barrett's Oesophagus What is the main RF/cause? What is the main complication? How is it managed along with the escalations?
Barrett's oesophagus or Intestinal metaplasia is where the squamous mucosa of the oesophagus becomes columnar => upward migration of the squamocolumnar junction (=> increased length of the squamocolumnar junction) Caused by chronic GORD Very high risk of adenocarcinoma a/w length of barret's oesophagus (or how much the squamocolumnar junction migrated upwards) Management: 1) Long term PPI (20mg) 2) Laser therapy 3) Resection
34
A patient presents with epigastric pain, acid reflux, and recurrent chest infections (but is currently well). What investigations should be performed for diagnosis?
Endoscopy referral or Barium study referral (best to assess dilatation and strictures - in general)
35
What is the medical management of GORD?
It is managed with the same escalations as Dyspepsia (Stop NSAIDs, bisphosphonates, SSRIs... -> PPI -> H2 receptor antagonist - Ranitidine) + If positive Endoscopy or evidence of dilatation on barium study, dosages for PPI would be full dose omeprazole (40mg) for 1 months and if severe, double dose (80mg) In Dyspepsia it was 1 month trial of 20mg omeprazole PRN/BD
36
What is the full management of GORD?
1) Lifestyle: Reduce weight Healthy diet avoiding precipitation by alcohol, coffee, chocolate, fatty foods. Smoking cessation Stop or reduce dosage of NSAIDs, Bisphosphonates (Ibandronate), steroids, SSRI.
37
can gastritis and peptic ulcers be used interchangeably? Define Acute Gastritis
nope theyre opposites Acute gastritis is mucosal inflammation of the stomach with NO ulcers
38
Acute gastritis is classified as Type A, B and C. What do each mean?
Type A - Entire stomach is affected Type B - Antrum + duodenum affected Type C - Inflammation due to irritants (NSAIDs, alcohol, bile reflux)
39
How does Acute gastritis present?
Just as dyspepsia Presents with: Epigastric pain Fullness bloating nausea/vomiting Heartburn Reflux Anaemia (+sx of anaemia)
40
What is the full management plan for Acute gastritis
Exactly the same as Dyspepsia. It presents the same way too 1) Lifestyle: Reduce weight Healthy diet avoiding precipitation by alcohol, coffee, chocolate, fatty foods. Smoking cessation Stop or reduce dosage of NSAIDs, Bisphosphonates (Ibandronate), steroids, SSRI. 2) Medical: a) PPI (20mg Omeprazole) for 1 month trial b) H2 receptor antagonist (Ranitidine) c) Prokinetic (Domperidone) d) Referral for endoscopy +PAC500 or PMC250 for H.pylori if confirmed
41
Go do PUD from med surg!!
Ya ttek
42
Differentiate between gastric and duodenal ulcers
Food: Gastric exacerbated by food, duodenum relieved Weight: Weight loss in gastric, weight gain in duodenal (makes sense) Nausea/vomiting, Fe anaemia more commonly and more severely occurs in gastric Duodenal ulcers mostly cause pain at night and early morning (when basically fasting) => sleep disturbance
43
What cell type(s) is/are most involved in oesophageal cancer Same for gastric
Oesophageal: 50% squamous cell and 50% adenocarcinoma Gastric: 95% adenocarcinoma
44
What is the presentation of oesophageal malignancy?
Rapidly progressive Dysphagia affecting solids first then liquids Weight loss Haematemesis Choking Cough/hoarseness => Aspiration => recurrent chest infections
45
You conduct barium swallow on a patient with dysphagia. There appears to be a stricture at the middle of the oesophagus. On OGD it is confirmed to be a carcinoma. You take a biopsy. What type of oesophageal carcinoma is it most likely? why?
As it occurs in the middle it is likely to be squamous cell carcinoma. Oesophagus is composed of squamous cells while the stomach is composed of columnar epithelium => in patients with GORD or acid reflux, barrett's oesophagus may occur leading to metaplasia. If the cancer is in the lower 1/3 it is likely to be adenocarcinoma. If the cancer is in the upper 2/3 it is likely to be
46
Give the strongest RF for Oesophageal malignancy and then give 4 others
Strongest = Barrett's oesophagus as part of chronic GORD Environmental (smoking, alcohol) Diet (obesity, low fruit intake) Mediastinal radiotherapy (hx of breast cancer or lymphoma) Plummer Vinson syndrome
47
What is Plummer Vinson Syndrome
Oesophageal web + Fe anaemia
48
What is the management of a patient with oesophageal carcinoma?

51
How would a patient with gastric carcinoma present?
Dyspepsia, weight loss, anorexia, early satiety Nausea/vomitting Anemia
52
How will you manage a patient presenting with gastrinoma?
Referral for endoscopy where it will be decided if the patient will undergo curative partial gastrectomy or palliative care (if late stage)
53
You refer a patient with a suspected gastric carcinoma for endoscopy. Results show a lesion that is curative via partial gastrectomy. What are the complications of partial gastrectomy
1) Abdominal fullness 2) Bilious vomiting/attack 3) Dumping (early/late) 4) Typical complications such as GA, VTE, haemorrhage, infection... 5) Diarrhoea 6) Anaemia 7) Gastric Ca recurrence (Partial gastrectomy itself is a RF for Gastric Ca, 7x risk)
54
What is abdominal fullness? What would you advise a patient post-gastrectomy to avoid this?
Feeling of early satiety +/- weight loss (basically like gastric sleeve). Advise the patient to have small but frequent meals
55
Intermittent sudden attacks of epigastric cramping pain after eating and is relieved by vomiting is consistent with? How would you resolve this?
Bilious vomiting as a complication of partial gastrectomy. Metoclopramide, surgical review if recurrent
56
Explain the concept of dumping as a complication of partial gastrectomy How is it generally managed?
Dumping is abdominal distension, colic, and vasomotor disturbance after meals. In english, this means that there is rapid gastric emptying into the duodenum Early dumping occurs directly after meals where rapid gastric emptying into duodenum activating chemo and baroreceptors to release large amounts of GI hormones. This leads to sweating, flushing, tachycardia, palpitations, nausea, and vomiting Late dumping occurs 1-3 hours after eating. Here it is due to the rapid absorption of glucose into bloodstream causing a spike. This causes insulin to respond, overcompensating leading to rebound hypoglycemia => faintness, tremor, sweating, and nausea Advise patients to have small, dry meals with restricted carb intake (refer to dietician)
57
Diarrhoea after partial gastrectomy is typically episodic and unpredictable. How would you manage this?
Loperamide
58
What type of anaemia typically occurs after a partial gastrectomy (assuming no haemorrhage)? How would you manage this?
Pernicious anaemia due to reduced B12 intrinsic factor (as we took off part of the stomach that produces it) => B12 injections and Fe supplements
59

61
Regarding an internal haemorrhoid, Define Haemorrhoid What is the lay word for haemorrhoid? How do haemorrhoids present? What examination should be performed? How would you manage this patient?
A haemorrhoid AKA pile is the distention of the submucosal plexus of veins in the anus, typically at 3 o clock, 7 o clock and 11 o clock (+4 each time) Presents with 1) Discomfort when sitting 2) Hematochezia with frank blood 3) Tenesmus 4) Mucous discharge 5) Pruritis Ani DRE should be performed to palpate and visualise the haemorrhoid and have it classified. Tx: 1) Treat constipation => Ispaghula Husk 2) Treat pain => Analgesia 3) Refer for surgical assessment if it does not settle
62
You conduct a DRE on a patient presenting with discomfort when sitting and hematochezia with frank blood. The patient complains of an itchy sensation as well. What is the most likely diagnosis? On examination nothing is palpable nor visible. Why would that be? What will you do next?
Haemorrhoids If nothing is visible or palpable on exam, it could be a 1st degree haemorrhoid!, poor examiner performance or alternate pathology => Refer for proctoscopy or sigmoidoscopy
63
What are the 2 main complications of haemorrhoids?
1) Strangulation (anal sphincter blocking vascular supply) 2) Thrombosis leading to perianal haematoma (or thrombosed external haemorrhoid) Both present with intense pain and anal sphincter spasm. If it does not settle with pain relief, icepacks and rest, admit.
64
A patient presents with discomfort and pruritis ani. You suspect haemorrhoids but on examination you note that there is none palpable or visible. The patient has no bleeding. What are alternate causes to this? What is the main complication associated with pruritis ani? what would you tell the patient to avoid this happening again?
1) Anus is soiled or moist due to poor hygiene, faecal incontinence, fistulas, fissures, tight underwear 2) Dermatological conditions such as Lichen Sclerosis and contact dermatitis Main complication: Threadworm infection which would appear as circular, well circumscribed erythematous lesions. Prevention: Encourage hygiene, loose underwear, avoid spicy food. Check for fistula or reason behind incontinence
65
What is a perianal haematoma? Define it How does it present?
It is a thrombosed external haemorrhoid due to ruptured superficial perianal vein causing a subcutaneous buildup of blood Just like a haemorrhoid but more acute and severe 1) Sudden onset Severe pain worse when sitting 2) Hematochezia with frank blood 3) Tenesmus 4) Mucous discharge 5) Pruritis Ani
66
A patient presents with sudden onset pain worse when sitting. They noted frank red blood on the tissue paper when wiping. They have a history of haemorrhoids. What is the most likely diagnosis? What examination findings would you expect to find for your most likely diagnosis? How would you manage?
Perianal haematoma (not the same as typical haemorrhoids but also called external thrombosed haemorrhoid) On exam, tender 2-4mm dark blueberry swelling under skin adjacent to anus GP: Pain => Analgesia Refer to hospital If <1 day old => small incision under local anaesthesia to evacuate haematoma
67
Rectal prolapse typically occurs wither in the very young or >60. What are the 2 types? If a 2 year old presents with their mother with evidence of rectal prolapse which type would it be and what would be the most likely cause? If a 65 year old woman presents with their mother with evidence of rectal prolapse which type would it be and what would be the most likely cause? If a 50 year old male presents with evidence of rectal prolapse which type would it be and what would be the most likely cause? In all of these cases, how would you manage?
2 types are: Mucosal: Bowel musculature not affected but the !redundant mucosa prolapses! Complete: Weak pelvic floor => descent of upper rectum into the lower anal canal causing !bowel wall prolapse! 2 year old => typically connective tissue disease such as Ehler danlos syndrome => complete due to weak pelvic floor 65 year old female => typically due to multiparity with large babies, prolonged straining, obesity, chronic cough, ace, smoking... or the most likely cause being menopause. In all cases, complete 50 year old male typically due to a !3rd degree haemorrhoid! => Mucosal In all cases, refer for surgery
68
A patient presents with pain on defecation, constipation and haematochezia. On examination, the anal mucosa appears to be torn on the posterior aspect. What is the most likely diagnosis? How would you manage this patient

Anal/perianal fistula Refer for surgical repair
72
There are 2 types of fistulas, high and low. Which type is more common? What are the causes of a high fistula? How would you determine if a fistula is considered high or low?
Low is more common High is rarer and caused by UC, Crohn's or a tumour Low and high are with respect to the deep external anal sphincter
73
A patient presents with a painful swelling on their very lower back. It is 2cm in diameter. It has a foul-smelling discharge which is sometimes blood-stained. What is the most likely diagnosis? What is the most likely cause of this? What is the most likely location of this? How is it managed
Pilonidal Sinus (pilonidus means hair-nest). Due to obstruction of hair follicle (in-grown hair) causing a foreign body reaction by immune system (may even form a fistula). Almost always occurs right above the tailbone. Based on severity either give antibiotics (practice) or refer for surgery (book)

Over 50% of patients are still symptomatic after 5 years despite management. How would you manage IBD in general?
1) Education: Explain that all investigations returned negative and that this is a diagnosis of exclusion. Also explain that it is very prevalent with over 20% of the population suffering from it. 2) Lifestyle changes a) Stress: Increased leisure time and regular physical activity (for both) b) Diet: Example here is for diarrhoea-dominant (use this to treat any diarrhoea rly unless infectious then do opposite) - Encourage patients to have regular meals and avoid missing meals or leaving long gaps between meals. - Ensure fluid intake is <8cups. Restrict caffeine, tea, fizzy drinks, and alcohol - Reduce intake of high-fibre foods - Reduce intake of resistant starch found in processed foods - Limit fresh fruit to 3 portions of 80g per day c) Food diary to identify foods that provoke symptoms d) dietician referral First it is important to note what type of IBS is present in order to give the correct advice. c) Specific measures: Constipation-predominant IBS - Fibre/bulking agents (Ispaghula Hulk) or laxatives (aboid lactulose) Diarrhoea-predominant - Loperamide (obv avoid weak opioids) Other therapies with evidence (just for your eyes to see): Probiotics, Antispasmodics (mebeverine or peppermint oil - try different ones as different preparations suit different people), FODMAP diet (dietitician), Low dose amitriptyline Psychotherapy
