#69 – Benign Breast Diseases



***LISTEN TO THE PODCAST HERE***



Anatomy and Physiology

  • Primary components of the breast are terminal duct lobular ubnits, lobular stroma, interlobular stroma, ducts, and lactiferous sinuses
    • Epithelium (terminal duct lobular units) is the most hormonally responsive
  • Natural hormonal changes of puberty, pregnancy, lactation, and menopause can lead to remodeling of these structures

Main Classifications

  • There are four main classifications of benign breast disorders that are based on the degree of cellular proliferations and atypia present
    • Nonproliferative
      • Characterized by acinar dilation and fibrosis
      • Generally, not associated with increased risk of cancer
    • Proliferative without atypia
      • Characterized by accumulation of luminal epithelial cells
      • Small increased risk of cancer (1.5-2x general population)
    • Atypical hyperplasia
      • Change in size, shape, or nuclear function of epithelial cells
      • High risk of cancer development
    • Miscellaneous

Epidemiology

  • 50% of women will experience a non-cancerous breast mass at some point in their lives
  • Age of diagnosis
    • Mean age of 51 years
      • Younger in proliferative
      • Older in atypical
  • Family History
    • Strongest in patients with atypical


NONPROLIFERATIVE DISORDERS

Breast Cysts

  • Most common
    • 25% of nonproliferative
    • 35-50 year olds
  • Fluid-filled, round mass originating from the terminal duct lobular unity
  • Patient Presentation
    • Painful or painless
    • Often solitary
  • Physical Examination
    • Smooth and firm to palpation with distinct border
  • Diagnostic Studies
    • Ultrasound
      • Simple
        • Anechoic throughout with posterior acoustic enhancement
      • Complicated
        • Homogenous low-level internal echoes with debris, thick walls, or thick septa
          • No solid components
      • Complex
        • Fluid and solid components without posterior wall enhancements
  • Management
    • Simple – no intervention required
    • Complicated – repeat imaging in 6 months
    • Complex – biopsy or FNA

Galactocele

  • Milk retention cysts usually caused by obstructed milk ducts
  • Physical Examination
    • Soft, cystic mass
  • Diagnostic Studies
    • Ultrasound
      • Complex echogenicity
  • Management
    • FNA reveals milky substance
    • No further intervention required

Hyperplasia of Usual Type

  • Increase in the number of epithelial cells within a duct that is more than two, but not more than four cells in depth and do not cross the lumen of the involved space

PROLIFERATIVE DISORDERS WITHOUT ATYPIA

Fibroadenoma

  • Most common benign tumor of the breast
    • 50% of all breast biopsies
    • 20% have multiple
  • Most common in younger women
    • 15-35 years of age
  • Likely hormonally driven
    • Persist through reproductive year’s, increase during pregnancy or with estrogen therapies, and decrease after menopause
  • Physical Examination
    • Well-defined, mobile mass on palpation
  • Diagnostic Studies
    • Ultrasound
      • Well-defined solid mass with isoechogenicity
  • Management
    • Biopsy is indicated to further stratify
      • Simple
        • Contains glandular and fibrous tissue
        • Watch vs excision vs cryoablation
          • If any change during observation, then excision is warranted
      • Complex
        • Contains duct epithelial hyperplasia or calcification
        • Observation vs excision

Intraductal Papilloma

  • Papillary cells that grown from the wall of a cyst into its lumen
  • Can hide areas of atypia or ductal carcinoma in situ
  • Two types
    • Solitary
      • Solid mass on examination or incidental imaging
      • Nipple discharge is common presenting sign
    • Multiple
      • Minimum of five papillomas within a localized segment of tissue
  • Diagnostic Studies
    • Often found on routine mammography, but ultrasound is recommended if there is a palpable mass
      • Will show a mass within a cystic space
  • Management
    • Solitary
      • Biopsy and excision if atypical cells present
    • Multiple
      • Excision of breast segment

Sclerosing Adenosis

  • Lobular lesions with increased fibrous tissue and interspersed glandular cells
  • Found on routine mammography
    • Architectural distortion with irregular borders and microcalcifications
  • No interventions needed outside of routine imaging

Radial Scar

  • Complex sclerosing lesions found on routine imaging AFTER biopsies or excisions have been performed
  • Pathologic by definition due to appearance
  • Diagnostic Studies
    • Mammography often shows low-intensity, spiculated masses that are indistinguishable from spiculated carcinomas
  • Management
    • Biopsy reveals fibroelastic cores with radiating ducts and lobules
    • Excision is recommended (though controversial) and is often definitive

PROLIFERATIVE LESIONS WITH ATYPIA

Atypical Ductal Hyperplasia (ADH)

  • Characterized by proliferation of uniform epithelial cells with monomorphic round nuclei filling the involved duct
    • Must be < 2mm or involving < 2 ducts
  • Can share cytologic and morphologic features of low-grade ductal carcinoma in-situ
  • Diagnosed by core needle biopsy
  • Management
    • Excisional breast biopsy with good margins

Atypical Lobular Hyperplasia (ALH)

  • Characterized by proliferation of monomorphic, evenly spaced, dyshesive cells filling the involved lobule
    • Generally found on incidental biopsy for other clinical reason
  • Can share cytologic and morphologic features of low-grade lobular carcinoma in-situ
  • Diagnosed by core needle biopsy
  • Management
    • Excisional breast biopsy with good margins

Lobular Carcinoma in-situ

  • Invasive lesion that arises from the lobules and terminal ducts of the breast
  • 80-90% of cases diagnosed in premenopausal women with a mean age of 45 year’s
  • Strong estrogen receptor positivity
  • Diagnosed by core needle biopsy on other incidental reason
    • LCIS is generally not diagnosed clinically, radiographically, or by gross pathologic examination
  • Three types
    • Classic
      • Solid proliferation of small cells with small, uniform round nuclei and variably distinct cell borders with cytologic dyshesion
      • Clear to lightly eosinophilic cytoplasm with possible signet ring cells and vacuoles
    • Pleomorphic
      • Larger cells with marked nuclear pleomorphism
    • Florid
      • Marked distension of the involved ducts and lobules that become mass-forming
      • Central necrosis with calcifications
  • Management
    • Excisional breast biopsy

Flat Epithelial Atypia

  • Characterized by neoplastic alteration of the terminal duct lobular units with replacement of the native epithelial cells with columnar cells
  • Diagnosed by core needle biopsy after mammographic evidence of microcalcifications
  • Management
    • Excisional breast biopsy

MISCELLANEOUS

Lipoma

  • Solitary mature fat tumors of the breast that do not contain histologic evidence of breast tissue
  • Physical Examination
    • Soft, non-tender, well-circumscribed mass
      • Difficulty to clinically differentiate from other conditions
  • Excisional biopsy is preferred

Fat Necrosis

  • Occurs as a result of breast trauma or surgical intervention
  • Can be confused with malignancy both clinically and radiographically
    • May see oil cysts on mammography or ultrasound
  • Biopsy is often needed to diagnose, but no further treatment is indicated

Diabetic Mastopathy

  • Seen in premenopausal women with long standing type 1 diabetes mellitus
  • Mammogram shows dense pattern
  • Diagnosed by core needle biopsy
    • Shows dense, keloid-like fibrosis with periductal, lobular, or perivascular lymphocytic infiltration
  • No further treatment after diagnosis

Hamartoma

  • Lesions containing varying amounts of glandular, adipose, or fibrous tissue
  • Present as discrete, encapsulated, painless masses found on incidental radiographic screening
  • FNA or CNB are not sufficient to make the diagnosis and excisional biopsy is preferred

Puestow Procedure

Other Known Aliases – Puestow-Gillesby procedure, lateral pancreaticojejunostomy

Definitionside-to-side anastomosis of the main pancreatic duct of Wirsung to the proximal jejunum

Clinical Significance this is a surgical management option for patients with chronic pancreatitis by simultaneously facilitating drainage and preserving physiologic function of the pancreas.

HistoryNamed after Charles Bernard Puestow (1902-1973), an American surgeon who recieved his medical doctorate from the University of Pennsylvania in 1925. He would serve as a military surgeon during the 2nd World War and commanded the 27th Evacuation Hospital providing surgical services to wounded soldiers in Europe and North Africa. His commitment to the veteran population would continue after the war when he established the first surgical residency program based in a veterans hospitals in the United States in 1946. It was at Hines Veterans Hospital in Illinois where he and his partner, William Gillesby, would publish their experience and outcomes on 21 patients with chronic pancreatitis in 1958, which would lead to the creation of his eponymonic surgical procedure.

Roux-en-Y Anastomosis

Other Known Aliasesend-to-end surgical anastomosis

Definitiongastrointestinal tract is divided into two limbs (proximal, Roux limb and a distal limb) and are re-anastomosed farther down the GI tract, typically in the jejunum

Clinical Significance this type of surgery is the traditional form of gastric bypass, where the proximal, Roux limb serves as the food reservoir and somach and the distal limb allows for physiologic drainage of gastric, hepatic, and pancreatic enzymes to aid in digestion. Other conditions it can be used is are chronic pancreatitis, alkaline gastritis, and various GI substitution procedures.

HistoryNamed after César Roux (1857-1934), who was a Swiss surgeon and received his medical doctorate from the University of Bern 1880. He would stay on at his alma mater and assist Theodor Kocher until 1887, when he became chief of surgery at cantonal hospital of Lausanne. He would go on to have a modest career in surgery notable for two historical accomplishments. In 1893, he performed his eponymous procedure on a patient with gastric strictures from peptic ulcer disease to alleviate his obstruction symptoms. In 1926, the year of his retirement, he was the first surgeon to successfully remove a pheochromocytoma….7 months before Charles Mayo performed the same operation in the United States. Harvey Cushing visited his clinic in 1900 and said “he is a rough diamond-looks like Kipling-does excellent work and comes nearer to being the kind of man I am looking for than anyone else I have seen”.

Whipple Procedure

Other Known Aliasespancreaticoduodenectomy

Definitionpancreaticoduodenectomy cholecystectomy, choledochojejunostomy, pancreaticojejunostomy, and gastrojejunostomy

Clinical Significance this type of surgery is performed to resect pancreatic head tumors. It generally performed at large, high-volume medical centers as this has been shown to reduce mortality to less than 5%. An experienced surgeon can complete this surgery in < 6 hours with < 500mL of blood loss. Barring any postoperative complications, most patients are discharged from the hospital in 7-10 days.

HistoryNamed after Allen Oldfather Whipple (1881-1963), who was an American surgeon and received his medical doctorate from Columbia University College of Physicians and Surgeons in 1908. He was appointed faculty at Columbia and Presbyterian Medical Centers before going on to become professor of surgery at his alma mater for the next 25 years. He published the report of his eponymous surgery in 1935 and only performed it 37 times in his lifetime. He also supervised Virginia Apgar and advised her to pursue a career in anesthesiology because he saw an “energy and ability to make significant contributions” that would advance both fields. Other notable accomplishments include helping establish the American Board of Surgery and establishing another eponymous diagnostic triad for insulinoma.

#61 – Cholelithiasis and Cholecystitis



***LISTEN TO THE PODCAST HERE***



Anatomy

  • 4 anatomic areas of gall bladder
    • Fundus
      • Rounded, blind end that extends 1-2 cm beyond the liver margin
      • Contains most of the smooth muscle
    • Body
      • Main storage area
      • Contains the elastic tissue allowing for distention
        • Normally holds 30-50mL and can stretch to 300mL
    • Infundibulum (Hartmann’s Pouch)
      • Mucosal outpouching at the junction of the neck and cystic duct
    • Neck
      • Lies in the deepest part of the fossa
  • Cystic Artery
    • Branch of the right hepatic artery
    • Found in the cystohepatic triangle
      • Cystic duct, common hepatic duct, superior/inferior margin of liver
      • Triangle of Calot
        • Cystic duct, common hepatic duct, cystic artery
        • Lymph node can be found in near the insertion of the cystic artery
          • Calot’s node (Lund’s or Mascagni’s)
  • Cystic duct
    • Spiral valves of Heister
      • Mucosal folds in the proximal cystic duct that make cannulation difficult
    • Joins the common hepatic duct to form the common bile duct
    • Highly variable anatomy

Physiology

  • 80% of bile is stored in the gall bladder
    • Infundibulum secretes glycoproteins to protect mucosa
  • Cholecystokinin released from neuroendocrine cells of the duodenum during meal
    • Stimulates release of bile from gallbladder
      • 50-70% over 30-40 minutes
    • Causes relaxation of Sphincter of Oddi
  • Vagal stimulation causes contraction of gallbladder

Stone Formation

  • Major solutes in bile are bilirubin, bile salts, phospholipids (lecithin), and cholesterol
  • 80% are cholesterol
    • Supersaturation of bile with cholesterol exceeds the ability of phospholipids and bile salts to maintain solubility

Pathogenesis of Cholecystitis

  • Phospholipid A (secreted by the gall bladder mucosa) released in response to gall bladder trauma (stone)
    • Catalyzes conversation of lecithin to lysolecithin
      • Leads to mucosal and luminal irritation and inflammation

Epidemiology and Risk Factors

  • 90-95% of patients with cholecystitis have stones
    • Only 20% of patients with stones with develop cholecystitis
    • 10-15% of patients have stones on autopsy
  • Risk Factors
    • High fat diet
    • Older age
    • Female > male
    • Higher BMI
      • Rapid weight loss
    • Pregnancy
    • Previous surgeries
      • Terminal ileum resection, gastric/duodenal surgery

Signs and Symptoms

  • History
    • Right upper quadrant abdominal pain
      • Steady, “boring” pain lasting hours
      • Worsened by fatty foods
    • Right scapular pain (Boas’ sign)
      • Hyperesthesia between 9th-11th rib
    • Fever, nausea, vomiting, anorexia
  • Physical Examination
    • Fever, tachycardia
    • Peritoneal signs
      • Pain with movement and percussion
    • Voluntary and involuntary guarding
    • +/- jaundice
    • Inspiratory arrest on deep RUQ palpation (Murphy’s sign)

Diagnostic Studies

  • Laboratory Studies
    • Leukocytosis with neutrophilic shift
    • LFTs generally normal, but may show:
      • Elevated direct (conjugated) bilirubin
      • Elevated alkaline phosphatase
      • Elevated GGT
  • Ultrasound is the initial test of choice
    • Length > 10 cm
    • Wall thickness > 3mm
    • Pericholecystic fluid
    • Sludge
  • Cholescintigraphy using 99m Tc-hepatic iminodiacetic acid (HIDA) Scan
    • Used if ultrasound is inconclusive
    • Intravenous injection of HIDA and visualization of dye in gallbladder, bile ducts, and small bowel within 30-60min
      • If not visualized after 1 hour, morphine can be given and waiting 3-4 hours
        • If no visualization = cholecystitis
  • Magnetic Resonance Cholangiopancreatography (MRCP)
    • Used if evidence of choledocolithiasis or elevated LFTs

Management

  • Admission
  • IV fluids
  • NSAIDs
    • Ketorolac 30-60mg IV/IM
  • Opioids
    • Meperidine NOT superior to morphine
  • Antibiotics
    • Low Risk
    • High Risk
  • Indication for Emergent Cholecystectomy
    • Necrosis
    • Perforation
    • Emphysematous cholecystitis
    • High fever
    • Hemodynamic instability
  • Interval Cholecystectomy (low risk)
    • Within 3 days of admission after therapies above and clinical improvement
    • Most can be discharged in 1-2 days postop
  • Gall bladder drainage (high risk)
    • Percutaneous cholecystostomy
      • Critically ill or septic
      • > 72 hours from symptom onset
      • Failure of antibiotic therapy
      • No coagulopathy
    • Endoscopic transpapillary/transmural drainage
      • Liver disease
      • Ascites
      • Coagulopathy
    • If improvement within 72 hours, proceed with laparoscopic cholecystectomy
      • If not, may need emergent open cholecystectomy
Percutaneous Cholecystostomy

Management Algorithm


Steps of Laparoscopic Cholecystectomy

  1. Dissect peritoneum overlying the cystic duct and artery
  2. Division and clipping of cystic duct close to gallbladder
    • Perform intraoperative cholangiogram to evaluate CBD
    • If clear, then two clips close to common bile duct and ligate
  3. Dissect cystic artery, one clip close distal and two clips proximal, and ligate
  4. Dissection of gall bladder from liver bed
  5. Cauterize, irrigate, suction, and obtain hemostasis of liver bed
  6. Remove gall bladder

Heller Myotomy

Other Known Aliasesnone

DefinitionLigation of the external muscle fibers of the lower esophageal sphincter

Clinical Significance this type of surgery can be open, laparoscopically, or endoscopically and is used to treat achalasia by relieving the constriction of the lower esophageal sphincter and allowing food to pass into the stomach. This is often combined with a Nissen fundoplication to prevent reflux after.

HistoryNamed after Ernst Heller (1877-1964), who was a German surgeon and received his medical doctorate from the University of Leipzig. He would serve as a military surgeon during the first World War from 1914-1918 before returning to Leipzig as chief surgeon of Saint George County Hospital. He had a fairly prestigous career in academic surgery, publishing over 80 scientific papers during his career and culminating as Professor of Surgery at the University of Leipzig in 1949. It was in 1913, as an assistant professor to Erwin Payr, that he performed his eponymous procedure on 39yo man with achalasia. He would publish this case report in 1914 and followed this patient for 7 years tracking his progression and documenting his now disease free condition.

Nissen Fundoplication

Other Known Aliasesnone

Definitionwrapping of the fundus of the stomach around the lower esophagus to re-enforce the LES and prevent esophageal sliding.

Clinical Significance this type of surgery can be performed open or laparoscopic to treat GERD with a hiatal hernia when medical management fails. Traditionally, a Nissen is a complete 360-degree wrap, and there are several variations of this procedure that involve incomplete wrapping on various sides of the esophagus.

HistoryNamed after Rudolph Nissen (1896-1981), who was a Jewish-German surgeon who received his medical doctorate from the University of Freiburg in 1921. His medical studies were interrupted by the first World War where he served on the front lines in a medical corp. It was during his service where he would suffer a gunshot to the lung, which would plague him for the rest of his life. He would go on to serve in various surgery departments in Munich, Berlin, and Istanbul where he would become the head of the surgery department in 1933. It was here that he resected an esophageal ulcer from a 28yo patient that required him to remove portion of the lower esophageal sphincter in the process. He decided to wrap a portion of the stomach around the lower esophagus to strengthen the sphincter and the patient reported greatly improved reflux symptoms. It wasn’t until 1955 when he reflected on this case and performed the procedure on two patients for reflux esophagitis and published the results in 1956. Of note, he also operated on Albert Einstein in 1948 to wrap his AAA with cellophane (which was the treatment at the time).
