What is diverticulosis?
Inflammation of colon pouches
Presence of colon pouches without inflammation
Bleeding from colon ulcers
Infection of hemorrhoids
Diverticulosis is defined as the presence of sac-like protrusions called diverticula in the colon without inflammation. It is often asymptomatic and discovered incidentally on imaging. High-fiber diets can help prevent progression.
Which part of the colon is most commonly affected by diverticulosis?
Ascending colon
Transverse colon
Sigmoid colon
Cecum
The sigmoid colon experiences the highest intraluminal pressure, making it the most common site for diverticula formation. This region is prone due to its narrower lumen. Recognition of this helps in diagnosis and imaging selection.
At what age does the prevalence of diverticulosis typically begin to rise markedly?
Before age 30
Age 30–40
Age 50–60
After age 80
Epidemiological studies show a sharp increase in diverticulosis prevalence after age 50. By age 60, up to 50% of individuals in Western countries have diverticula. Aging leads to structural changes in the colon wall that favor diverticula formation.
Which of the following is a hallmark symptom of hemorrhoids?
Painless rectal bleeding
Fever
Severe abdominal pain
Weight loss
Hemorrhoids often present with bright red, painless bleeding during defecation because they are vascular cushions under low pain sensitivity. This symptom differentiates them from other anorectal conditions. Proper history taking can identify bleeding patterns.
Internal hemorrhoids are located:
Below the dentate line
Above the dentate line
In the sigmoid colon
In the rectosigmoid junction
Internal hemorrhoids originate from the superior hemorrhoidal plexus above the dentate line, making them less painful. They can prolapse and bleed but often lack significant discomfort. Differentiation from external hemorrhoids guides treatment selection.
What dietary change is recommended to help prevent diverticulosis complications?
Low-fat diet
High-protein diet
High-fiber diet
Liquid-only diet
A high-fiber diet increases stool bulk, reducing colonic intraluminal pressure and the likelihood of diverticula formation or progression. Fiber intake is inversely associated with diverticular disease risk. Guidelines recommend 25–30 g of fiber daily.
Diverticulitis differs from diverticulosis in that it involves:
Presence of diverticula without symptoms
Bleeding only
Inflammation of diverticula
Cancerous changes in the colon
Diverticulitis occurs when one or more diverticula become inflamed or infected, often causing abdominal pain and fever. Diverticulosis describes the mere presence of diverticula. Correct distinction ensures appropriate management.
Which vessels become engorged in hemorrhoidal disease?
Arterial arcades
Superior rectal veins
Mesenteric veins
Iliac arteries
Hemorrhoids result from dilation of the superior rectal venous plexus (internal) and inferior rectal plexus (external). Venous engorgement leads to prolapse and bleeding. Identifying venous anatomy is critical for surgical planning.
A common precipitating factor for hemorrhoid flare-ups is:
High-fiber intake
Straining during defecation
Frequent exercise
Oral antibiotics
Straining at stool increases anorectal venous pressure, exacerbating hemorrhoidal dilation. Chronic constipation and low-fiber diets promote straining, worsening symptoms. Addressing bowel habits is first-line management.
Which of these is the mainstay of conservative treatment for both diverticulosis and hemorrhoids?
Antibiotics
High-fiber diet
Sitz baths
Topical steroids
High-fiber diets help maintain regular bowel movements and reduce intraluminal pressure in diverticulosis, while also reducing straining associated with hemorrhoids. Fiber supplements like psyllium are recommended. Lifestyle modification is essential for prevention and symptom relief.
What is the most common presentation of diverticular bleeding?
Painful bleeding
Painless hematochezia
Melena only
Rectal pain without bleeding
Diverticular bleeding typically presents as sudden, painless bright red or maroon rectal bleeding due to erosion of vasa recta at the diverticulum neck. The absence of pain helps differentiate it from diverticulitis. Endoscopic evaluation can localize the bleeding source.
Which statement about hemorrhoid grading is correct?
Grade I protrudes and requires manual reduction
Grade II requires surgical removal
Grade III prolapses and requires manual reduction
Grade IV is asymptomatic
Grade III hemorrhoids prolapse on defecation and must be manually reduced. Grade I do not prolapse, and Grade II reduce spontaneously. This classification informs treatment choices.
True or false: All colonic diverticula contain all layers of the bowel wall.
True
False
Most colonic diverticula are pseudodiverticula that include only mucosa and submucosa herniating through the muscular layer. True (or full-thickness) diverticula are rare and often congenital. Recognizing this aids surgical planning.
Which lifestyle modification is least likely to improve diverticulosis?
Increasing dietary fiber
Regular exercise
Heavy weight lifting
Adequate hydration
Heavy weight lifting can increase intra-abdominal pressure and may worsen diverticular disease. In contrast, fiber intake, hydration, and exercise help maintain healthy bowel function. Patients are advised to avoid straining.
Which of these symptoms would most likely prompt evaluation for diverticulitis rather than diverticulosis?
Left lower quadrant pain with fever
Painless rectal bleeding
Occasional constipation
No symptoms
Diverticulitis commonly presents with left lower quadrant pain, fever, and sometimes leukocytosis. Painless bleeding is more typical of uncomplicated diverticulosis. Recognizing acute signs guides urgent imaging and management.
A patient with grade IV hemorrhoids would most likely have:
Internal hemorrhoids only
Prolapsed hemorrhoids that cannot be reduced
Asymptomatic bulges
Painless bleeding only
Grade IV hemorrhoids are permanently prolapsed and cannot be manually reduced, often requiring surgical intervention. They may thrombose or ulcerate if untreated. Prompt referral is recommended.
What imaging modality is considered the gold standard for diagnosing acute diverticulitis?
Abdominal X-ray
Ultrasound
Contrast-enhanced CT scan
MRI
Contrast-enhanced CT scan accurately identifies pericolonic inflammation, abscesses, and complications of diverticulitis. It has high sensitivity and specificity and guides management decisions. Ultrasound may be used in pregnant patients or when CT is unavailable.
Which antibiotic regimen is first-line for uncomplicated diverticulitis in an outpatient setting?
Amoxicillin alone
Metronidazole plus ciprofloxacin
Vancomycin
Doxycycline
The combination of metronidazole plus a fluoroquinolone (e.g., ciprofloxacin) covers gram-negative and anaerobic organisms implicated in diverticulitis. Recent guidelines may allow monotherapy with certain broad-spectrum agents. Antibiotic choice depends on local resistance patterns.
Which factor most strongly increases risk for both hemorrhoids and diverticular disease?
Smoking
High-fiber diet
Chronic constipation
Female sex
Chronic constipation leads to increased straining and intraluminal pressure, promoting diverticula formation and exacerbating hemorrhoidal engorgement. Managing bowel habits is crucial to reduce risk. Other factors have less direct impact.
Which endoscopic finding is most consistent with diverticulosis?
Ulcerative lesions
Multiple outpouchings of mucosa
Continuous mucosal inflammation
Polyps only
Colonoscopy in diverticulosis shows multiple mucosal outpouchings most frequently in the sigmoid colon. Biopsies are not routinely required unless bleeding source is unclear. Inflamed diverticula are approached cautiously to avoid perforation.
What is the recommended follow-up colonoscopy interval after an episode of complicated diverticulitis?
1 month
6 weeks
1 year
No follow-up needed
A colonoscopy is typically performed 6–8 weeks after an episode of complicated diverticulitis to exclude malignancy or other pathology. Early endoscopy risks perforation, and very delayed evaluation may miss lesions. Timing balances safety and diagnostic yield.
Rubber band ligation is most appropriate for which grade of hemorrhoids?
Grade I
Grade II
Grade III
Grade IV
Rubber band ligation is the treatment of choice for symptomatic Grade II hemorrhoids and select Grade III hemorrhoids. It involves strangulating the hemorrhoidal tissue, causing it to slough off. It is minimally invasive with quick recovery.
Which complication is least common in diverticulosis?
Perforation
Bleeding
Fistula formation
Abscess
Fistula formation is more characteristic of complicated diverticulitis rather than diverticulosis. Bleeding, microperforation leading to abscess, and inflammation can occur when diverticula become complicated. Recognizing true complications differentiates management strategies.
Which proctologic procedure involves excision of hemorrhoidal tissue?
Sclerotherapy
Hemorrhoidectomy
Infrared coagulation
Rubber band ligation
Hemorrhoidectomy is the surgical removal of hemorrhoidal tissue and is indicated for Grade III–IV hemorrhoids or those refractory to office-based therapies. It provides definitive treatment but with longer recovery. Less invasive options may be considered first.
Which finding on CT scan suggests a diverticular abscess?
Localized fluid collection with rim enhancement
Diffuse colonic wall thickening only
Free air under diaphragm
Mesenteric lymphadenopathy
An abscess appears as a localized fluid collection with peripheral rim enhancement on contrast-enhanced CT. Wall thickening alone suggests simple inflammation. Free air indicates perforation. Identification guides percutaneous drainage.
Postoperative recurrence rates of hemorrhoids are highest after which procedure?
Stapled hemorrhoidopexy
Open hemorrhoidectomy
Closed hemorrhoidectomy
Rubber band ligation
Stapled hemorrhoidopexy has higher recurrence rates compared to conventional hemorrhoidectomy, especially for external components. It offers less postoperative pain, but patients may require reintervention. Procedure selection balances morbidity and durability.
Which laboratory finding is most likely in acute diverticulitis?
Leukopenia
Elevated C-reactive protein
Low ESR
Thrombocytopenia
Patients with acute diverticulitis often have elevated inflammatory markers such as CRP and leukocytosis. CRP correlates with severity and helps monitor response. Normal or low CRP argues against significant inflammation.
Which of the following is a contraindication to colonoscopy during acute diverticulitis?
Mild diverticulosis
Active perforation
Completed antibiotic therapy
No abdominal pain
Active perforation or abscess is a contraindication to endoscopy because of the risk of exacerbating perforation and peritonitis. Colonoscopy can be performed after resolution to exclude malignancy. Timing is crucial for patient safety.
Which genetic factor has been implicated in an increased risk of diverticular disease?
MTHFR mutation
ELN gene variants
BRCA1 mutation
HFE gene mutation
Variants in the elastin gene (ELN) have been linked to connective tissue changes that predispose to diverticula formation. Elastin deficiency can weaken the colonic wall. Genome-wide studies continue to uncover genetic associations.
Which cytokine profile is associated with complicated diverticulitis?
High IL-10 only
Elevated TNF-? and IL-6
Low IL-1? and IL-8
Isolated high IL-2
Complicated diverticulitis is associated with elevated proinflammatory cytokines TNF-? and IL-6, reflecting severe tissue inflammation. IL-6 levels correlate with abscess formation and perforation risk. Cytokine profiling may inform future therapeutic targets.
Which surgical approach has the lowest short-term morbidity for acute complicated diverticulitis?
Hartmann’s procedure
Primary resection with anastomosis and proximal diversion
Diverting colostomy only
Laparoscopic lavage
Primary resection with anastomosis and proximal diversion offers lower morbidity than a two-stage Hartmann’s procedure in selected patients with contained abscesses. Patient selection and surgical expertise are critical. It avoids permanent stoma in many cases.
Which advanced imaging feature suggests an enterocolic fistula in diverticular disease?
Air in the bladder
Oral contrast extravasation into adjacent loop of small bowel
Thickened bladder wall
Free intraperitoneal fluid only
Fistula formation can be seen as contrast from the colon tracking into adjacent small bowel loops on CT or barium studies. Early identification facilitates surgical planning. Other signs include inflammation across organ planes.
Which minimally invasive procedure for hemorrhoids preserves anoderm and reduces pain?
Rubber band ligation
Stapled hemorrhoidopexy
Open hemorrhoidectomy
Sclerotherapy
Stapled hemorrhoidopexy repositions prolapsed hemorrhoidal tissue using a circular stapler above the dentate line, sparing anoderm and reducing postoperative pain. It is effective for Grade III hemorrhoids. Long-term recurrence rates are higher than excisional methods.
Which microbiome alteration has been observed in patients with symptomatic uncomplicated diverticular disease?
Overgrowth of Bifidobacterium species
Reduced Firmicutes-to-Bacteroidetes ratio
Increased Lactobacillus species
Absence of E. coli
Studies show a reduced Firmicutes-to-Bacteroidetes ratio in symptomatic uncomplicated diverticular disease, suggesting dysbiosis. This imbalance may contribute to mucosal inflammation. Probiotic therapy is being investigated as treatment.
Which factor most influences the decision to perform a sigmoid colectomy after recurrent uncomplicated diverticulitis?
Number of episodes alone
Patient’s comorbidities and quality of life impact
Age under 40 always requires surgery
Presence of diverticula on imaging
Current guidelines recommend individualized decisions based on severity, frequency of episodes, patient comorbidities, and life impact rather than a fixed number of recurrences. Elective surgery after multiple uncomplicated attacks may be considered if quality of life is poor. Shared decision-making is essential.
What is the mechanism of action of infrared coagulation for hemorrhoids?
Sclerosing agent injection
Thermal coagulation of hemorrhoidal tissue
Mechanical banding
Cryotherapy
Infrared coagulation uses focused infrared light to induce superficial thermal injury, causing fibrosis and shrinking of hemorrhoidal cushions. It is effective for small grade I–II internal hemorrhoids. Complication rates are low.
Which surgical technique uses a circular stapler placed above the dentate line?
Milligan-Morgan hemorrhoidectomy
Stapled hemorrhoidopexy
Doppler-guided dearterialization
Closed hemorrhoidectomy
Stapled hemorrhoidopexy employs a circular stapler to excise a ring of prolapsed rectal mucosa and submucosa, lifting hemorrhoidal tissue back into the anal canal. It treats prolapse with less postoperative pain than conventional excision. Patient selection is key.
Which predictor is most associated with failure of outpatient management of diverticulitis?
Absence of fever on presentation
Elevated heart rate >90 bpm
White cell count <10,000/mm³
Age under 50
Tachycardia (heart rate >90 bpm) indicates systemic inflammation or sepsis and predicts poor response to outpatient antibiotics. Outpatient criteria also include absence of comorbidities and ability to tolerate oral intake. This triage improves safety.
Which anatomic variation increases risk of sigmoid diverticulosis?
Long, redundant sigmoid colon
Short mesenteric attachment
Wide rectosigmoid angle
Dilated ileocecal valve
A long, redundant sigmoid colon can increase intraluminal pressure and stasis, promoting diverticula formation. Colon length variants correlate with disease distribution. Imaging may reveal this trait.
What is the most effective nonsurgical therapy to reduce hemorrhoid bleeding episodes?
Phlebotonic agents (e.g., flavonoids)
Topical antibiotics
Oral steroids
Daily aspirin
Phlebotonic agents like flavonoids improve venous tone, reduce capillary permeability, and decrease hemorrhoidal bleeding. Meta-analyses support their benefit as adjunctive therapy. They are well tolerated.
Which molecular pathway is implicated in the pathogenesis of diverticular disease via extracellular matrix remodeling?
TGF-?/SMAD signaling
Wnt/?-catenin pathway
Notch signaling
Hedgehog pathway
TGF-? signaling via SMAD transcription factors regulates collagen deposition and extracellular matrix remodeling in the colon wall. Dysregulation contributes to diverticula formation and fibrosis. Research into inhibitors is ongoing.
Which novel endoscopic technique is under investigation for bleeding diverticula?
Over-the-scope clip (OTSC)
Radiofrequency ablation
Argon plasma coagulation
Cryoablation
OTSC provides a strong mechanical closure of bleeding diverticular defects, achieving hemostasis in difficult-to-reach sites. Early studies show promising control of recurrent bleeding. It may reduce need for surgery.
In which patient population is the prevalence of hemorrhoids paradoxically low?
Long-distance runners
Sedentary office workers
Pregnant women
Elderly bedbound patients
Long-distance runners often have more frequent bowel movements with less straining and improved pelvic floor tone, reducing hemorrhoid risk. This contrasts with sedentary individuals who may strain more. Data suggest exercise benefits anal vascular health.
Which quality metric predicts hospital readmission after an acute diverticulitis admission?
Length of stay >7 days
Inadequate discharge instructions on diet
Age <40 years
Use of IV antibiotics only
Studies show that incomplete discharge planning regarding diet and follow-up significantly increases readmission rates for diverticulitis patients. Ensuring patient education reduces recurrence. Institutional protocols aim to standardize discharge.
Which surgical anatomy landmark is critical to preserve continence during hemorrhoidectomy?
Anoderm 1 cm from dentate line
Pectinate line
Internal sphincter insertion
Submucosal plane 3 cm above dentate line
Preserving the anoderm starting about 1 cm distal to the dentate line prevents damage to sensory nerves critical for continence. Excision too low increases postoperative fecal incontinence risk. Anatomical knowledge guides safe excision margins.
What is the role of microRNA-145 in diverticular disease?
Promotes smooth muscle proliferation
Downregulates extracellular matrix genes
Enhances inflammatory cytokine release
Increases collagen cross-linking
MicroRNA-145 regulates genes involved in matrix remodeling by downregulating extracellular matrix components. Reduced miR-145 expression correlates with impaired collagen architecture in diverticular disease. It represents a potential biomarker.

Cheat Sheet

  1. Pathophysiology of diverticulosis hemorrhoids -

    Study the pathophysiology underlying diverticulosis hemorrhoids to appreciate distinct mechanisms: diverticula form from increased intraluminal pressure causing mucosal outpouchings, while hemorrhoids are swollen vascular cushions in the anal canal. Remember the mnemonic "DIVA" (Diverticula = Increased Valsalva Activity) to link straining with diverticular development. According to Mayo Clinic, connective-tissue weakness and chronic straining are central pathogenetic factors.

  2. Key Risk Factors & Prevention -

    Common risk factors include advanced age, low-fiber diets, obesity and sedentary lifestyle, all of which elevate intraluminal pressure and venous stasis. Use the mnemonic "FABO" (Fiber deficiency, Age, BMI high, Obstructive straining) to recall major triggers. Cleveland Clinic guidelines emphasize early dietary modification to prevent both diverticulosis and hemorrhoids.

  3. Clinical Presentation & Differentiation -

    A clear understanding of hemorrhoids diverticulosis presentations ensures accurate diagnosis: diverticulitis often presents with left lower quadrant pain and fever, whereas hemorrhoids typically cause bright-red rectal bleeding and anal pruritus. Distinguish between hemorrhoids or diverticulitis by noting systemic signs like fever or leukocytosis, per guidelines from the American Gastroenterological Association.

  4. Diagnostic Workup -

    A CT scan of the abdomen with contrast is the gold standard for diagnosing diverticulitis, while anoscopy or proctoscopy visualizes internal hemorrhoids. Recall the "CATCH" mnemonic (CT scan, Anoscopy, Colonoscopy judiciously, Tests for occult blood, History taking) to structure your workup per American Society of Colon and Rectal Surgeons recommendations. Always tailor imaging and endoscopic studies to clinical severity and patient stability.

  5. Management & Lifestyle Strategies -

    Management of diverticulosis and hemorrhoids emphasizes high-fiber diets (25 - 30 g daily) and adequate hydration to soften stool and reduce straining. For acute hemorrhoids, rubber-band ligation or sclerotherapy may be used, while uncomplicated diverticulitis often responds to outpatient antibiotics per AGA protocols. Remember the "FIRE" mnemonic (Fiber, Increase fluids, Regular exercise, Eliminate straining) to help patients recall key lifestyle modifications.
