Pancreatitis and Colon Cancer Quiz

Altered Elimination GI Focus

• Altered stool elimination includes obstruction and peritonitis
• Appendicitis involves inflammation of the appendix, often due to infection or blockage
• Diverticular disease is characterized by pouches (diverticula) in the colon wall
• Gallbladder disease involves the gallbladder, potentially including gallstones (cholelithiasis) and inflammation (cholecystitis)
• Acute and chronic pancreatitis are inflammatory conditions of the pancreas
• Pancreatic cancer is a type of cancer that develops in the pancreas
• Colon polyps and colon cancer are conditions related to the colon
• Additional cancers to consider include kidney, bladder, and colon cancer

Stool Elimination Process-Review

• Fecal matter enters the cecum through the ileocecal valve
• Peristalsis is the major process for moving food; it involves sequential muscle contractions
• Segmentation is the mixing of chyme and digestive juices within the small intestine to propelling
• Water and electrolyte removal is a critical function in the colon
• Rectal sphincter relaxation is part of stool evacuation

General Manifestations of Altered Bowel Elimination

• Assessing altered stool volume, stool characteristics, and bleeding (e.g., melena, hematochezia) are crucial
• Pain and abdominal distension are common symptoms
• Anorexia, nausea, and vomiting, and fever may also accompany altered bowel function

Altered Bowel Elimination

• 1. Altered motility affects water and vitamin absorption, storage time, and risk of obstruction potentially leading to diarrhea or constipation
• 2. Altered perfusion (global or focal) causes ischemia and infarction, hence resulting in painful consequences
• 3. Intestinal bowel obstruction involves a blockage in the gut (e.g., tumors, hernias)

Bowel Obstruction Etiology and Clinical Manifestations

• Mechanical causes include adhesions, radiation, surgery, fecal impaction, hernias, intussusception, trauma, or tumors
• Functional causes include inflammation (diverticulitis), medication effects (e.g., anticholinergics, opioids), and neurological or autonomic disorders
• Common symptoms include abdominal pain, swelling, lack of appetite, profuse vomiting in small bowel obstruction, decreased bowel sounds without gas, and no bowel sounds or constipation

Treatment of Bowel Obstruction

• NPO (nothing by mouth)
• Nasogastric tube (NG) placement
• Colon resection (if necessary)
• Colostomy or stoma formation (if necessary)

Bowel Obstruction Complications

• Small bowel obstruction can lead to fluid and electrolyte imbalance, impaired mobility, ischemia (tissue death), distention, perforation (tearing), and potentially peritonitis leading to infection; treatment is urgent
• Large bowel obstruction mainly causes distention, cramping, and constipation, also potentially life threatening complications

A Bowel Obstruction Complication: Peritonitis

• Peritonitis is an inflammation of the peritoneum membrane, a potential, and serious complication of a bowel obstruction
• Causes include ascites, ruptured organs, trauma, peritoneal dialysis contamination, bowel obstruction, and infection
• Clinical manifestations may include fever, abdominal distention, rebound tenderness, and absent or decreased bowel sounds.
• Treatment requires fluids, electrolytes, NG tube for bowel rest, antibiotics, and possible surgery

Obstruction can lead to sepsis and shock!

• Obstruction results in potentially life threatening issues like no bowel sound distally to the obstruction, increased abdominal contraction and pressure, nausea, and vomiting.
• Obstruction can lead to sepsis and shock as a result of peritonitis, perforation and other complications

Appendicitis

• Inflammation of the appendix can lead to infections from fecal contents
• Signs include elevated WBCs
• Symptoms typically start with abdominal pain that migrates to the right lower quadrant (RLQ), nausea, vomiting, and even fever
• Treatment involves surgical removal; early intervention is often preferred

Diverticulum/Diverticulitis

• Diverticulum are small sacs or pouches that can form in the lining of the colon
• Diverticulosis, presence of diverticula without inflammation
• Diverticulitis is an inflammation of these pouches often related to fecal material accumulation which causes inflammation and infection.
• Risks include chronic constipation, and prolonged pressure on the colon walls altering structure and function
• Diagnosis includes a physical exam, history of symptoms and abdominal tenderness or distension

Diverticular Disease Clinical Manifestations and Diagnosis

• Diverticular disease typically causes symptoms in the left lower quadrant
• Consequences can include decreased gut motility, obstruction, impaired perfusion, perforation, or hemorrhage.
• Diagnosis involves symptom history, physical exam, and assessing for abdominal tenderness and distention

Diverticular Disease Diagnostics and Treatment

• Labwork (stool analysis, complete blood count)
• Imaging modalities like ultrasound, MRI, or CT to assess for inflammation or rupture
• Endoscopy (colon or sigmoidoscopy) to visualize the affected area
• Treatment involves management of symptoms and bowel rest, antibiotics if infection is present, and occasionally surgical intervention for perforated diverticula

Gallbladder Diseases (Cholelithiasis, Cholecystitis)

• Cholelithiasis: presence of gallstones within the gallbladder or bile ducts
• Cholecystitis: inflammation of the gallbladder itself, usually secondary to gallstones obstructing the bile duct
• Risk factors include Female, Fair complexion, Fat (obese), Fertile or has children, and Forty years of age+
• Symptoms typically include pain in the right upper quadrant, nausea, vomiting, or sometimes jaundice
• Treatment includes extracorporeal shockwave lithotripsy (removing the gallstones using vibrations) or cholecystectomy
• Cholecystogram or ultrasound can be utilized for diagnostics

Acute Pancreatitis Pathophysiology and Clinical Manifestations

• Pancreatitis involves inflammation of the pancreas, potentially acute or chronic; a possible and serious consequence of bile duct blockage or excessive alcohol use
• Pancreatic injury damages acinar cells (amylase and lipase production) and protective digestive feedback mechanisms, leading to inflammation
• Clinical manifestations often include upper abdominal pain, sudden onset, intensifying pain, dull ache radiating to the back, nausea, vomiting, anorexia, and diarrhea.

Acute Pancreatitis Diagnostic Criteria

• Elevated lipase and amylase levels: crucial indicators for diagnosis
• Liver function tests (LFTS), assessment of alcohol use, checking triglyceride levels, abdominal pain evaluation, abdominal imaging (x-ray, CT scan) is used
• Clinical examination and elevated amylase and lipase levels

Acute Pancreatitis Treatment

• Intravenous hydration, NPO, and analgesics are common initial treatments
• Endoscopy may be needed
• Cholecystectomy if gallstones are the culprit
• Symptomatic treatment for idiopathic pancreatitis
• If alcohol is the cause, interventions often include interventions, palliative care, and quitting alcohol

Pancreatic Cancer

• Pancreatic cancer, often adenocarcinoma, commonly develops in the head of the pancreas
• Causes include idiopathic origins, smoking, chemical exposure, and high-fat diets
• Symptoms may include abdominal and back pain, nausea/vomiting, loss of appetite, weakness/fatigue, and jaundice
• Diagnosis typically involves biopsy
• Treatment commonly includes surgery (Whipple procedure), radiation therapy, and chemotherapy.

Colon Polyps and Colon Cancer

• Colon polyps are growths inside the colon. Benign or pre-cancerous ones can develop into adenocarcinomas.
• Colon polyps formation and progression can be caused by inflammation and/or neoplasms.
• Colonoscopy or sigmoidoscopy can be utilized for diagnostics
• Suspicious or cancerous polyps are often removed
• Risk factors include genetics, age, low fiber diet, smoking, and some inflammatory conditions

Colon Cancer

• Colon cancer exhibits DNA mutation in the colon wall
• Risk factors include genetics, older age, low fiber diet, smoking, excessive alcohol consumption, and certain inflammatory conditions (Crohn's or ulcerative colitis)
• Clinical manifestations are evident through constipation, abdominal fullness, rectal bleeding, occult blood in stool, back pain, and weight loss.
• Colonoscopy with biopsy is frequently used for diagnosis
• Treatment often involves colon resection, chemotherapy, or radiation therapy.
