  • Review of anatomy and physiology of gastrointestinal system and accessory organs

Anatomy and Physiology of the Gastrointestinal (GI) System and Accessory Organs


1. Overview of the Gastrointestinal System

The gastrointestinal (GI) system, also known as the digestive system, is responsible for the ingestion, digestion, absorption, and excretion of food and nutrients.


2. Anatomy of the GI Tract

A. Major Structures

  1. Mouth:
    • Function: Begins digestion through mastication (chewing) and mixing food with saliva.
    • Enzymes: Salivary amylase begins carbohydrate digestion.
  2. Pharynx and Esophagus:
    • Pharynx: Transports food from the mouth to the esophagus.
    • Esophagus: A muscular tube that propels food to the stomach via peristalsis.
  3. Stomach:
    • Anatomy: Includes the fundus, body, and pylorus.
    • Function: Stores and mixes food with gastric juices to form chyme.
    • Enzymes and Secretions:
      • Hydrochloric acid (HCl): Activates pepsinogen to pepsin.
      • Pepsin: Begins protein digestion.
      • Intrinsic factor: Required for vitamin B12 absorption.
  4. Small Intestine:
    • Sections: Duodenum, jejunum, ileum.
    • Function:
      • Duodenum: Continues digestion with bile and pancreatic enzymes.
      • Jejunum and Ileum: Absorb nutrients into the bloodstream.
    • Special Features:
      • Villi and microvilli increase the surface area for absorption.
  5. Large Intestine:
    • Sections: Cecum, colon (ascending, transverse, descending, sigmoid), rectum.
    • Function:
      • Absorbs water and electrolytes.
      • Forms and stores feces.
      • Houses beneficial gut bacteria that produce vitamins (e.g., vitamin K).
  6. Rectum and Anus:
    • Function: Excretes waste as feces through defecation.

3. Accessory Organs

These organs assist in digestion but are not part of the GI tract.

A. Salivary Glands

  • Types: Parotid, submandibular, sublingual.
  • Function: Secrete saliva containing salivary amylase to start carbohydrate digestion.

B. Liver

  • Anatomy: Largest gland in the body, located in the upper right abdomen.
  • Functions:
    1. Produces bile to emulsify fats.
    2. Detoxifies drugs and toxins.
    3. Stores glycogen, vitamins (A, D, E, K, B12), and iron.
    4. Synthesizes plasma proteins (e.g., albumin) and clotting factors.

C. Gallbladder

  • Function:
    • Stores and concentrates bile produced by the liver.
    • Releases bile into the duodenum via the common bile duct.

D. Pancreas

  • Anatomy: Lies posterior to the stomach.
  • Functions:
    1. Exocrine Function:
      • Produces digestive enzymes:
        • Amylase (carbohydrates), lipase (fats), proteases (proteins).
      • Secretes bicarbonate to neutralize stomach acid.
    2. Endocrine Function:
      • Produces insulin and glucagon to regulate blood sugar.

4. Physiology of the Digestive Process

A. Ingestion

  • Food enters the mouth, where it is mechanically broken down and mixed with saliva.

B. Digestion

  1. Mechanical Digestion:
    • Chewing in the mouth.
    • Churning in the stomach.
    • Segmentation in the small intestine.
  2. Chemical Digestion:
    • Enzymatic breakdown of macronutrients:
      • Carbohydrates → Monosaccharides.
      • Proteins → Amino acids.
      • Fats → Fatty acids and glycerol.

C. Absorption

  • Nutrients are absorbed primarily in the small intestine:
    • Carbohydrates and Proteins: Absorbed into the bloodstream.
    • Fats: Absorbed into the lymphatic system via lacteals.

D. Excretion

  • Indigestible substances and waste are excreted as feces through the rectum and anus.

5. Regulation of the Digestive System

A. Neural Regulation:

  1. Enteric Nervous System:
    • Controls local reflexes and GI motility.
    • Includes the myenteric (motility) and submucosal (secretion) plexuses.
  2. Autonomic Nervous System:
    • Parasympathetic stimulation increases digestion.
    • Sympathetic stimulation decreases digestion.

B. Hormonal Regulation:

  1. Gastrin:
    • Stimulates gastric acid secretion and motility.
  2. Secretin:
    • Stimulates bicarbonate secretion from the pancreas.
  3. Cholecystokinin (CCK):
    • Stimulates bile release from the gallbladder and enzyme release from the pancreas.
  4. Motilin:
    • Promotes intestinal motility.

6. Disorders Related to the GI and Accessory Organs

  1. GERD, peptic ulcers, IBS, IBD.
  2. Gallstones (cholelithiasis), liver diseases (cirrhosis, hepatitis).
  3. Pancreatitis, malabsorption syndromes.

Key Points for Nursing Management

  1. Assess: Monitor signs of GI dysfunction (pain, vomiting, stool changes).
  2. Interventions:
    • Provide nutritional support (e.g., specialized diets, enteral feeding).
    • Administer medications (antacids, antiemetics, enzymes).
  3. Education:
    • Teach patients about healthy eating habits.
    • Emphasize hydration and fiber intake for bowel health.
  • Pathophysiology, diagnostic procedures and management of G.I.Bleeding

Gastrointestinal (GI) Bleeding: Overview

Definition:
Gastrointestinal bleeding refers to any bleeding that occurs in the digestive tract, which can range from minor to life-threatening. It is classified based on the source of bleeding as upper GI bleeding (UGIB) or lower GI bleeding (LGIB).


Pathophysiology

  1. Upper GI Bleeding:
    • Originates from the esophagus, stomach, or duodenum.
    • Common Causes:
      • Peptic ulcer disease (gastric or duodenal ulcers).
      • Esophageal varices (due to portal hypertension).
      • Gastritis or esophagitis.
      • Mallory-Weiss tear (tear in the mucosa at the gastroesophageal junction).
      • Malignancies (gastric cancer).
  2. Lower GI Bleeding:
    • Originates from the small intestine, colon, rectum, or anus.
    • Common Causes:
      • Diverticulosis (pouches in the colon wall).
      • Colitis (inflammatory bowel disease, ischemic colitis, infectious colitis).
      • Hemorrhoids or anal fissures.
      • Colorectal cancer or polyps.
      • Angiodysplasia (abnormal blood vessels in the GI tract).

Pathological Mechanisms:

  • Inflammation, erosion, or ulceration of the GI mucosa leads to vessel damage and bleeding.
  • Increased pressure in veins (e.g., portal hypertension) causes rupture of fragile vessels (e.g., varices).
  • Trauma or mechanical tears disrupt mucosal integrity (e.g., Mallory-Weiss tear).

Clinical Presentation

  1. Upper GI Bleeding:
    • Hematemesis (vomiting blood; bright red or coffee-ground appearance).
    • Melena (black, tarry stools due to digested blood).
  2. Lower GI Bleeding:
    • Hematochezia (bright red or maroon blood in stools).
    • Occult bleeding (not visible but detected via tests).
  3. General Symptoms:
    • Fatigue, dizziness, or syncope (due to anemia or hypovolemia).
    • Hypotension, tachycardia (signs of significant blood loss).
    • Abdominal pain or discomfort (depending on the cause).

Diagnostic Procedures

  1. History and Physical Examination:
    • Detailed history of symptoms, medication use (e.g., NSAIDs), alcohol consumption, or previous GI diseases.
    • Physical examination for signs of anemia or shock.
  2. Laboratory Tests:
    • Complete Blood Count (CBC): Check hemoglobin, hematocrit, and platelet count.
    • Coagulation Profile: PT, INR, aPTT for bleeding disorders.
    • Liver Function Tests (LFTs): For suspected varices or liver disease.
    • Blood Type and Cross-Match: In case transfusion is needed.
  3. Endoscopy:
    • Esophagogastroduodenoscopy (EGD): Gold standard for diagnosing upper GI bleeding.
    • Colonoscopy: To diagnose lower GI bleeding.
    • Findings: Ulcers, varices, tumors, angiodysplasia.
  4. Imaging Studies:
    • Abdominal CT Angiography: For active bleeding in lower GI.
    • Radionuclide Scanning: To localize obscure GI bleeding.
  5. Occult Blood Tests:
    • Fecal Occult Blood Test (FOBT): Detects hidden blood in stool.
  6. Capsule Endoscopy:
    • Used for small bowel bleeding.

Management

A. Immediate Stabilization

  1. Airway and Breathing:
    • Ensure airway patency in patients with hematemesis.
    • Oxygen therapy if hypoxemia is present.
  2. Circulatory Support:
    • IV fluids (normal saline or Ringer’s lactate) to restore volume.
    • Blood transfusion for significant anemia or hypovolemia.
    • Monitor vital signs and urine output.

B. Pharmacological Management

  1. Proton Pump Inhibitors (PPIs):
    • Examples: Pantoprazole, Omeprazole.
    • Purpose: Reduce acid production and promote ulcer healing.
  2. Octreotide:
    • Reduces portal venous pressure in variceal bleeding.
  3. Antibiotics:
    • Used prophylactically in variceal bleeding to prevent infections (e.g., ceftriaxone).
  4. Vasopressin:
    • Used in acute variceal bleeding to constrict blood vessels.
  5. H2 Receptor Antagonists:
    • Examples: Ranitidine (less effective than PPIs).

C. Endoscopic Management

  1. For Upper GI Bleeding:
    • Endoscopic hemostasis using:
      • Injection therapy (epinephrine).
      • Thermal coagulation.
      • Mechanical methods (clips, bands).
    • Band ligation for varices.
  2. For Lower GI Bleeding:
    • Endoscopic polypectomy for polyps.
    • Coagulation or clipping for angiodysplasia.

D. Surgical Management

  • Indicated when endoscopic and medical therapy fail.
  • Procedures include resection of the bleeding segment or ligation of bleeding vessels.

E. Interventional Radiology

  1. Angiographic Embolization:
    • Used for persistent or recurrent bleeding when endoscopy is unsuccessful.
  2. Transjugular Intrahepatic Portosystemic Shunt (TIPS):
    • Used in variceal bleeding unresponsive to other treatments.

Nursing Management

  1. Assessment:
    • Monitor vital signs for hypovolemic shock (e.g., tachycardia, hypotension).
    • Observe for signs of continued bleeding (e.g., hematemesis, melena).
  2. Interventions:
    • Administer prescribed medications (PPIs, octreotide).
    • Prepare the patient for endoscopy or surgery.
    • Ensure IV access for fluids and blood transfusions.
  3. Education:
    • Teach the patient about dietary modifications (e.g., avoiding alcohol, spicy foods).
    • Emphasize adherence to medication regimens.
    • Educate on the importance of follow-up care to prevent recurrence.

Complications

  1. Hypovolemic shock.
  2. Anemia and related fatigue.
  3. Perforation of ulcers leading to peritonitis.
  4. Recurrent bleeding.
  5. Multi-organ failure in severe cases.
  • Peptic ulcer

Peptic Ulcer: Overview

Definition:
A peptic ulcer is a break or sore in the lining of the stomach, duodenum, or esophagus due to the corrosive action of stomach acid and pepsin. It occurs when the balance between protective factors (e.g., mucus, bicarbonate) and aggressive factors (e.g., acid, pepsin, Helicobacter pylori) is disrupted.


Types of Peptic Ulcers

  1. Gastric Ulcers:
    • Located in the stomach lining.
    • More common in older adults.
  2. Duodenal Ulcers:
    • Found in the first part of the small intestine (duodenum).
    • More common than gastric ulcers and usually occur in younger individuals.

Causes

  1. Helicobacter pylori (H. pylori) Infection:
    • The most common cause.
    • Damages the mucosal lining, making it vulnerable to acid.
  2. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs):
    • Examples: Aspirin, ibuprofen.
    • Reduce prostaglandin production, which is essential for mucosal protection.
  3. Hypersecretory Conditions:
    • Zollinger-Ellison syndrome (excessive acid production due to gastrin-secreting tumors).
  4. Lifestyle Factors:
    • Smoking, excessive alcohol use, stress.
  5. Others:
    • Genetic predisposition.
    • Radiation therapy to the stomach.

Pathophysiology

  1. Disruption of the protective mucosal barrier or increased acid production.
  2. Exposure of the stomach/duodenal lining to gastric acid and pepsin.
  3. Inflammation and erosion of the mucosa.
  4. If untreated, complications such as bleeding, perforation, or obstruction can occur.

Symptoms

  1. Common Symptoms:
    • Burning or gnawing abdominal pain.
    • Pain location:
      • Gastric ulcers: Pain worsens with eating.
      • Duodenal ulcers: Pain relieved by eating but worsens 2–3 hours after meals.
    • Nausea, bloating, or belching.
  2. Severe Symptoms (Complications):
    • Hematemesis (vomiting blood, coffee-ground appearance).
    • Melena (black, tarry stools).
    • Sudden severe pain (indicates perforation).

Diagnosis

  1. History and Physical Examination:
    • Assess symptoms, medication use (NSAIDs), and lifestyle habits.
  2. Endoscopy (EGD):
    • Gold standard for diagnosing ulcers.
    • Allows visualization and biopsy to rule out malignancy or H. pylori.
  3. Non-Invasive Tests for H. pylori:
    • Urea breath test.
    • Stool antigen test.
    • Serology for H. pylori antibodies (less specific).
  4. Imaging:
    • Barium swallow (used less frequently).
  5. Laboratory Tests:
    • Complete blood count (CBC) to assess for anemia.
    • Occult blood test for hidden blood in stool.

Management

A. Medical Management

  1. Eradication of H. pylori:
    • Triple therapy:
      • Proton pump inhibitor (PPI): Omeprazole or Pantoprazole.
      • Two antibiotics: Amoxicillin + Clarithromycin or Metronidazole.
    • Quadruple therapy (if resistance to triple therapy):
      • PPI + Bismuth subsalicylate + Metronidazole + Tetracycline.
  2. Acid Suppression:
    • Proton Pump Inhibitors (PPIs): Reduce gastric acid secretion.
    • H2-Receptor Blockers: Ranitidine, Famotidine.
    • Antacids: Neutralize stomach acid and provide symptomatic relief.
  3. Protective Agents:
    • Sucralfate: Forms a protective barrier over ulcers.
    • Misoprostol: Prostaglandin analog for patients on NSAIDs (contraindicated in pregnancy).
  4. Lifestyle Modifications:
    • Avoid NSAIDs, smoking, alcohol, and spicy foods.
    • Manage stress.

B. Surgical Management

  1. Indications:
    • Complications like perforation, obstruction, or recurrent bleeding.
    • Failure of medical therapy.
  2. Procedures:
    • Vagotomy: Cutting the vagus nerve to reduce acid secretion.
    • Partial gastrectomy: Removal of the ulcerated part of the stomach.
    • Pyloroplasty: Widening the pylorus to improve gastric emptying.

Complications

  1. Bleeding:
    • Symptoms: Hematemesis, melena, anemia.
    • Management: Endoscopic hemostasis, blood transfusion.
  2. Perforation:
    • Symptoms: Sudden, severe abdominal pain, peritonitis.
    • Management: Emergency surgery.
  3. Gastric Outlet Obstruction:
    • Symptoms: Vomiting, abdominal distension.
    • Management: Endoscopic dilation or surgery.
  4. Malignancy:
    • Rarely, chronic ulcers can lead to gastric cancer.

Nursing Management

Assessment:

  • Cholecystitis

Cholecystitis: Overview

Definition:
Cholecystitis refers to inflammation of the gallbladder, typically caused by obstruction of the cystic duct, often due to gallstones (cholelithiasis). It can be acute or chronic.


Types of Cholecystitis

  1. Acute Cholecystitis:
    • Sudden inflammation, usually due to gallstones.
    • May involve infection (e.g., E. coli, Klebsiella).
  2. Chronic Cholecystitis:
    • Repeated episodes of acute inflammation leading to gallbladder wall thickening and scarring.

Causes

  1. Gallstones (Cholelithiasis):
    • Block the cystic duct, leading to bile stasis and inflammation.
  2. Acalculous Cholecystitis:
    • Inflammation without gallstones, often in critically ill patients.
  3. Risk Factors:
    • Female gender, obesity, rapid weight loss, high-fat diet, pregnancy.
    • Certain medical conditions (e.g., diabetes, Crohn’s disease).

Pathophysiology

  1. Gallstones obstruct the cystic duct or gallbladder neck.
  2. Bile becomes trapped, leading to increased pressure and irritation of the gallbladder wall.
  3. Secondary infection by bacteria may occur.
  4. Chronic cases involve repeated injury and scarring of the gallbladder wall.

Symptoms

Hepatitis: Overview

Definition:
Hepatitis refers to inflammation of the liver, caused by viral infections, toxins, autoimmune conditions, or other factors. It can be acute (short-term) or chronic (lasting more than six months).


Types of Hepatitis

  1. Viral Hepatitis:
    • Hepatitis A: Fecal-oral transmission; acute.
    • Hepatitis B: Blood, body fluids, perinatal transmission; acute or chronic.
    • Hepatitis C: Bloodborne; commonly chronic.
    • Hepatitis D: Requires Hepatitis B co-infection; severe chronic disease.
    • Hepatitis E: Fecal-oral transmission; acute, severe in pregnancy.
  2. Non-Viral Hepatitis:
    • Alcoholic hepatitis.

Hepatic Coma (Hepatic Encephalopathy)


Definition:

Hepatic coma, also known as hepatic encephalopathy (HE), is a neuropsychiatric syndrome caused by liver dysfunction. It occurs due to the accumulation of toxins (primarily ammonia) in the bloodstream, affecting brain function.


Causes:

  1. Acute Liver Failure:
    • Viral hepatitis.
    • Drug toxicity (e.g., acetaminophen overdose).
  2. Chronic Liver Disease:
    • Cirrhosis is the most common underlying condition.
  3. Precipitating Factors:
    • Gastrointestinal bleeding.
    • Infections (e.g., spontaneous bacterial peritonitis).
    • Electrolyte imbalances (e.g., hypokalemia, alkalosis).
    • Excess protein intake or constipation.
    • Use of sedatives or diuretics.

Pathophysiology:

  1. Liver dysfunction leads to reduced clearance of ammonia and other neurotoxins.
  2. Ammonia crosses the blood-brain barrier, altering neurotransmitter levels.
  3. This results in impaired brain function and progressive neurological decline.

Symptoms:

  1. Early Stages (Mild HE):
    • Confusion, forgetfulness.
    • Personality changes.
    • Difficulty concentrating and handwriting changes (asterixis or “flapping tremor”).
  2. Advanced Stages:
    • Drowsiness, lethargy.
    • Stupor progressing to coma (hepatic coma).

Diagnosis:

  1. Clinical Assessment:
    • Presence of underlying liver disease.
    • Neurological evaluation.
  2. Laboratory Tests:
    • Elevated serum ammonia levels.
    • Abnormal liver function tests (elevated ALT, AST, bilirubin).
    • Prolonged PT/INR.
  3. Imaging:
    • CT or MRI to rule out structural brain abnormalities.

Management:

  1. Correct Precipitating Factors:
    • Treat infections with antibiotics.
    • Stop gastrointestinal bleeding.
    • Correct electrolyte imbalances.
  2. Medications:
    • Lactulose:
      • Reduces ammonia absorption by acidifying the colon and promoting bowel movements.
    • Rifaximin:
      • Antibiotic that reduces ammonia-producing gut bacteria.
    • Neomycin/Metronidazole:
      • Alternative antibiotics for ammonia control.
  3. Nutritional Support:
    • Protein restriction during acute episodes.
    • High-carbohydrate diet to maintain energy.
  4. Supportive Care:

  • ortal hypertension

Portal Hypertension: Overview

Definition:
Portal hypertension is an increase in blood pressure within the portal venous system, which consists of the portal vein and its branches. It occurs when blood flow through the liver is obstructed, leading to elevated pressure in the portal vein.


Causes of Portal Hypertension

  1. Prehepatic Causes (Before the Liver):
    • Portal vein thrombosis.
    • Splenic vein thrombosis.
  2. Intrahepatic Causes (Within the Liver):
    • Cirrhosis (most common cause).
    • Hepatitis.
    • Schistosomiasis.
    • Primary biliary cholangitis or sclerosing cholangitis.
  3. Posthepatic Causes (After the Liver):
    • Budd-Chiari syndrome (hepatic vein obstruction).
    • Constrictive pericarditis.
    • Right-sided heart failure.

Pathophysiology

  1. Obstruction or damage to the liver increases resistance to blood flow in the portal venous system.
  2. Blood reroutes through collateral vessels (e.g., esophageal, gastric, rectal veins), leading to varices.
  3. Increased pressure and collateral circulation result in complications such as ascites, variceal bleeding, and splenomegaly.

Symptoms

  1. Early Symptoms:
    • Fatigue.
    • Mild abdominal discomfort.
  2. Advanced Symptoms:
    • Ascites (abdominal fluid accumulation).
    • Esophageal or gastric varices (which may bleed).
    • Splenomegaly (enlarged spleen).
    • Caput medusae (dilated abdominal wall veins).
    • Rectal varices (leading to hemorrhoids).

Complications

  1. Variceal Bleeding:
    • Life-threatening gastrointestinal hemorrhage from ruptured varices.
  2. Ascites:
    • Fluid accumulation in the peritoneal cavity.
  3. Splenomegaly:
    • Leads to hypersplenism, causing thrombocytopenia, anemia, and leukopenia.
  4. Hepatic Encephalopathy:
    • Toxin accumulation leading to neurological symptoms.
  5. Hepatorenal Syndrome:
    • Renal failure due to reduced renal blood flow.

Diagnosis

  1. History and Physical Examination:
    • Symptoms of chronic liver disease.
    • Signs of portal hypertension (ascites, varices).
  2. Laboratory Tests:
    • Liver function tests: Elevated ALT, AST, bilirubin.
    • Coagulation profile: Prolonged PT/INR.
    • Complete blood count: Anemia, thrombocytopenia.
  3. Imaging:
    • Ultrasound with Doppler: Evaluates blood flow in the portal vein and detects splenomegaly or ascites.
    • CT/MRI: Visualizes varices, liver abnormalities, and vascular changes.
  4. Endoscopy:
    • Detects esophageal and gastric varices.
  5. Hepatic Venous Pressure Gradient (HVPG):
    • Confirms portal hypertension by measuring pressure differences between the portal vein and hepatic vein.

Management

A. Medical Management

  1. Reduce Portal Pressure:
    • Non-selective Beta-Blockers:
      • Examples: Propranolol, Nadolol.
      • Reduce portal blood flow and prevent variceal bleeding.

      • Example: Isosorbide mononitrate (used selectively).
  2. Prevent Variceal Bleeding:
    • Vasoactive Drugs:
      • Octreotide, Terlipressin: Reduce splanchnic blood flow.
    • Endoscopic Band Ligation (EBL):
      • Ties off varices to prevent bleeding.
  3. Control Ascites:
    • Sodium restriction and diuretics (e.g., Spironolactone, Furosemide).
    • Large-volume paracentesis for severe cases.
    • Albumin infusion to prevent complications after paracentesis.
  4. Antibiotics:
    • Used for spontaneous bacterial peritonitis (SBP) prophylaxis (e.g., Ciprofloxacin, Norfloxacin).

B. Surgical and Interventional Management

  • hernias,

Hernias: Overview

Definition:
A hernia occurs when an organ or tissue pushes through a weak spot or opening in the muscle or connective tissue that normally holds it in place. Hernias can occur in various parts of the body but are most common in the abdominal region.


Types of Hernias

  1. Inguinal Hernia (most common):
    • Occurs in the groin area.
    • Indirect Inguinal Hernia: Through the inguinal canal, common in infants and younger adults.
    • Direct Inguinal Hernia: Through a weak point in the abdominal wall, common in older adults.
  2. Femoral Hernia:
    • Bulge appears below the inguinal ligament in the upper thigh.
    • More common in women.
  3. Umbilical Hernia:
    • Occurs near the navel (umbilicus), often in infants or obese adults.
  4. Hiatal Hernia:
    • The upper part of the stomach protrudes into the chest through the diaphragm.
  5. Incisional Hernia:
    • Occurs at the site of a previous surgical incision.
  6. Epigastric Hernia:
    • Occurs in the upper abdomen, between the navel and the lower part of the ribcage.
  7. Obturator Hernia:
    • Rare hernia through the obturator canal, usually seen in elderly women.
  8. Spigelian Hernia:
    • Occurs along the edge of the rectus abdominis muscle.

Causes

  1. Increased Intra-abdominal Pressure:
    • Heavy lifting, chronic coughing, or straining during bowel movements.
    • Obesity, pregnancy, or ascites.
  2. Weakness in the Abdominal Wall:
    • Congenital defects.

  • fissures,

Fissures: Overview

Definition:
A fissure is a small tear or crack in the lining of the skin or mucosa, often causing pain and bleeding. The most common type is an anal fissure, which occurs in the lining of the anus.


Types of Fissures

  1. Anal Fissure:
    • Tear in the anal mucosa.
    • Can be acute (heals within 6 weeks) or chronic (persists beyond 6 weeks).
  2. Other Fissures:
    • Fissures in the lips (cheilitis).
    • Fissures in the tongue (glossitis).

Causes

  1. Common Causes:
    • Trauma from passing hard stools (constipation).
    • Chronic diarrhea.
    • Straining during defecation.
  2. Other Causes:
    • Anal sphincter hypertonia (increased tone of the anal muscles).
    • Inflammatory conditions (e.g., Crohn’s disease, ulcerative colitis).
    • Anal infections (e.g., sexually transmitted infections).
    • Trauma during childbirth or anal intercourse.

Pathophysiology

  1. A tear occurs in the mucosa due to trauma or strain.
  2. The internal anal sphincter contracts, reducing blood flow to the area.
  3. Reduced blood flow delays healing and exacerbates pain, leading to a vicious cycle.

Symptoms

  1. Pain:
    • Sharp, severe pain during and after bowel movements.
    • Lasts for minutes to hours.

  • hemorrhoids.

Hemorrhoids: Overview

Definition:
Hemorrhoids, also known as piles, are swollen and inflamed veins in the rectum and anus. They can cause discomfort, pain, and rectal bleeding and are classified into internal or external types based on their location.


Types of Hemorrhoids

  1. Internal Hemorrhoids:
    • Located inside the rectum.
    • Typically painless but may cause bleeding.
    • Classified into grades:
      • Grade I: No prolapse, just prominent blood vessels.
      • Grade II: Prolapse upon straining but spontaneously reduce.
      • Grade III: Prolapse and require manual reduction.
      • Grade IV: Prolapsed and cannot be manually reduced; may become thrombosed.
  2. External Hemorrhoids:
    • Located under the skin around the anus.
    • Often painful, especially if thrombosed.
  3. Mixed (Interno-External) Hemorrhoids:
    • Involves both internal and external components.

Causes

  1. Increased Pressure in Rectal Veins:
    • Chronic constipation or diarrhea.
    • Straining during bowel movements.
    • Prolonged sitting on the toilet.
  2. Lifestyle Factors:
    • Low-fiber diet.
    • Obesity.
    • Sedentary lifestyle.
  3. Other Factors:
    • Pregnancy (increased abdominal pressure and hormonal changes).
    • Aging (weakened rectal and anal tissues).
    • Family history of hemorrhoids.

Pathophysiology

  1. Increased pressure in the rectal veins leads to dilation and weakening of venous walls.
  2. This results in the formation of hemorrhoidal cushions, which may protrude or become thrombosed.

Symptoms

  1. Internal Hemorrhoids:
    • Painless rectal bleeding (bright red blood during defecation).
    • Mucous discharge or itching.
    • Prolapse in advanced stages.
  2. External Hemorrhoids:
    • Pain or discomfort around the anus.
    • Swelling and irritation.
    • Thrombosis (blood clot) causing severe pain and a hard lump.

Diagnosis

  1. History and Physical Examination:
    • Assess for rectal bleeding, pain, and prolapse.
  2. Digital Rectal Examination (DRE):
    • Detects lumps or abnormalities.
  3. Proctoscopy or Anoscopy:
    • Direct visualization of internal hemorrhoids.
  4. Colonoscopy or Sigmoidoscopy:
    • Rule out other causes of rectal bleeding (e.g., colorectal cancer, inflammatory bowel disease).

Management

A. Non-Surgical Management

  1. Lifestyle Modifications:
    • High-fiber diet to soften stools.

    • A rubber band is placed around the base of an internal hemorrhoid, cutting off blood flow and causing it to fall off.
  2. Sclerotherapy:
    • Injection of a chemical solution to shrink hemorrhoids.
  3. Infrared Coagulation:
    • Heat is used to coagulate blood vessels in internal hemorrhoids.
  4. Cryotherapy:
    • Freezing the hemorrhoids to cause tissue necrosis.

C. Surgical Management

  1. Hemorrhoidectomy:
    • Surgical removal of hemorrhoids.
    • Used for Grade III or IV hemorrhoids or when other treatments fail.
  2. Stapled Hemorrhoidopexy (PPH):
    • Uses a circular stapler to reposition prolapsed hemorrhoids and reduce blood flow.
  3. Thrombectomy:
    • Removal of a blood clot from thrombosed external hemorrhoids.

Complications

  1. Bleeding or infection after surgery.
  2. Stricture or narrowing of the anal canal.
