26
Q

What is proctalgia fugax?

A

Intermittent sharp pain in the rectum or anus lasting for seconds to minutes.

27
Q

What are the different types of functional anorectal pain syndromes?

A

28
Q

What is dyssynergic defecation?

A

Dyssynergic defecation is a functional defecation disorder characterized by
- incomplete evacuation,
- incomplete contraction of the pelvic muscles,
- incomplete sphincter relaxation.

29
Q

What is diverticulosis?

A

Bulging of mucosa, submucosa and muscularis externa through the muscular layer of the colon

30
Q

What is the difference between a pseudodiverticulum and a diverticulum in diverticular disease?

A

Pseudodiverticulum is bulging of mucosa and submucosa through the muscular layer, while diverticulum is bulging of every layer.

31
Q

What is the pathophysiology of diverticular disease?

A
  • Oral obstruction of the diverticulum,
  • irritation of food residues,
  • mucosal injury,
  • local bacterial overgrowth leading to inflammation.
32
Q

What is the triad of symptoms in diverticulitis?

A

Left LQ pain, fever, leukocytosis.

33
Q

How is diverticulitis diagnosed?

A
  • History,
  • physical examination,
  • lab tests (WE, CRP, leukocytosis),
  • imaging (US, CT - gold standard).
  • Colonoscopy
34
Q

What is the therapy for symptomatic, uncomplicated diverticulosis?

A
  • Diet and lifestyle changes,
  • ensuring proper fiber intake,
  • and antibiotic rifaximin.
35
Q

What is the therapy for acute diverticulitis?

A
  • Broad-spectrum antibiotic for 7-10 days or observation (ampicillin-sulfabactam / ciprofloxacin-metronidazole)
  • might need hospitalisation (if risk population)
36
Q

What is the recommended therapy for diverticular bleeding?

A
  • Angiographic embolisation : vasopressin
  • Endoscopic therapy : cauterisation, clips
37
Q

What is the recommended therapy for diverticular abscess?

A

<4cm
- Parentéral feeding

> 4cm
- US or CT guided drainage

Fistulas
- Resection of affected intestinal tract

38

  • perforation
44
Q

45
Q

What is ischemic colitis?

A

Ischemic colitis is a condition where there is inadequate blood supply to the colon, leading to decreased bowel motility, abdominal pain, and bloody stools.

46
Q

What are the causes of ischemic colitis?

A
  • constriction or embolization of the superior and inferior mesenteric arteries
  • in some cases, no specific cause can be identified.
47
Q

What are the symptoms of ischemic colitis?

A
  1. hyperactive phase (severe abdominal pain and bloody stools),
  2. paralytic phase (widespread abdominal pain, decreased bowel motility, bloating, and no further bloody stools),
  3. shock phase (leaky gut, dehydration, low BP, metabolic acidosis, tachycardia, and confusion).
48
Q

What is the therapy for ischemic colitis?

A
  • IV fluid,
  • bowel rest,
  • antibiotics covering aerobic and anaerobic bacteria,
  • surgical intervention if necessary.
49
Q

What is chronic idiopathic nausea ?

A
  • Nausea more than once a week

  • Negative pan endoscopy
50
Q

What drugs can be given for IBS?

A
  • spasmolytic Ca antagonists (pinaverin),
  • laxatives,
  • TCA
  • SSRI
  • rifaximin
51
Q

A

Meckel’s diverticulum

52
Q

Which drugs can be used to lower NSAID complications?

  • nitrogen monoxide
  • H2S-producing NSAIDs.
53
Q

How to differentiate ischemic colitis and mesenteric ischemia?

A

Mesenteric ischemia has weight loss, nausea and vomiting, and not always bloody stool
