Approach to Abdominal Pain Dr. Margaret Gluszynski Dr. Shauna Bassel
Slide 2-

Why is this important? Abdominal pain is one of the most common reasons for outpatient and ER visits A lot can happen in the abdomen and you need an organized approach
Slide 3-

Just a few diagnoses to ponder… Esophagitis GERD Gastric ulcer Gastritis Duodenal ulcer Duodenitis Gastric outlet obstruction Bowel obstruction Intussusception Bowel perforation Cancer Hepatitis Splenic infarct Splenic abscess Mesenteric ischemia Somatization IBS Crohn’s disease Ulcerative colitis Gastroenteritis Familial Mediterranean fever Acute intermittent porphyria Appendicitis AAA rupture Esophageal spasm Diverticulitis Ectopic pregnancy Pelvic inflammatory disease Fitz-Hugh-Curtis HSV Abdominal epilepsy Endometriosis Vitamin D deficiency Adrenal insufficiency Pancreatitis Cholangitis Cholecystitis Choledocholithiasis Incarcerated hernia UTI Nephrolithiasis Abdominal migraine Celiac artery compression syndrome Uterine pathology HIV Hemophilia Sickle cell disease Trauma Pneumonia Subdiaphragmatic abscess Myocardial infarction Pericarditis Prostatitis Idiopathic inflammatory disorders Epiploic appendagitis Hereditary angioedema Painful rib syndrome Wandering spleen syndrome Abdominal wall pain Leukemia HSP Lead poisoning
Slide 4-

So how do we organize this? Location Acute v. chronic Type of pain

Slide 6-

Acute abdominal pain Generally present for less than a couple weeks Usually days to hours old Don’t forget about the chronic pain that has acutely worsened More immediate attention is required Surgical v. nonsurgical
Slide 7-

Chronic abdominal pain Generally present for months to years Generally not immediately life threatening Outpatient work-up is prudent
Slide 8-

Understanding the Types of Abdominal Pain Visceral Crampy, achy, diffuse Poorly localized Somatic Sharp, cutting, stabbing Well localized Referred Distant from site of generation Symptoms, but no signs
Slide 9-

Approach to the patient History is THE MOST IMPORTANT part of the diagnostic process Location, quality, severity, radiation, exacerbating or alleviating factors, associated symptoms Visceral v. peritoneal A good thorough medical history (including sexual and menstrual) A good thorough social history, including alcohol, drugs, domestic abuse, stressors, travel etc. Family history is important (IBD, cancers, etc) MEDICATION INVENTORY
Slide 10-

Approach to the patient Physical exam Vitals (incl postural), general appearance A good thorough medical exam Jaundice, signs of chronic liver disease, CVAT Abdominal exam Look, listen, feel Know a few tricks DRE Pelvic exam, GU MSK exam
Slide 11-

Approach to the patient Labs CBC, lytes, BUN, Cr, coags Amylase and lipase, LFTs UA bHCG Lactate Tox screen H. pylori serology FOBT
Slide 12-

Approach to the patient Imaging Plain films (KUB, UGI) CT Ultrasound MRI Angiography Endoscopy EGD Colonoscopy ERCP/EUS
Slide 13-

Surgical abdomen This is the first thing to be considered in acute abdominal pain Early identification is a must as prognosis worsens rapidly with delay in treatment Important to get surgeons involved early if this is even mildly suspected This is a clinical diagnosis
Slide 14-

Surgical abdomen Presentation is usually bad Fevers, tachycardia, hypotension VERY tender abdomen, possibly rigid Presentation can vary with other demographic and medical factors Advanced age Immunosuppression
Slide 15-

Surgical abdomen Peritonitis Often signals an intraabdominal catastrophe Perforation, big abscess, severe bleeding Patient usually appears ill Exam findings Rebound, rigidity, tender to percussion or light palpation, pain with shaking bed
Slide 16-

Surgical abdomen Work-up Start with stat labs Surgical abdominal series (plain films) Consider stat CT if readily available Sometimes patients go straight to surgery as initial step Again, get surgeons involved early for guidance and early intervention
Slide 17-

Constipation 1. Presence of >= 2 of the following for at least 3 months (with symptom onset at least 6 months prior to diagnosis): Straining for >25% of defecations Lumpy/hard stools >25% of defecations Sensation of incomplete evacuation >25% of defecations Sensation of anorectal obstruction/blockage >25% of defecations Manual maneuvers to facilitate >25% of defecations (eg, digital evacuation, support of the pelvic floor) < 3 defecations/week 2. Loose stools are rarely present without the use of laxatives 3. There are insufficient criteria for IBS.
Slide 18-

Etiology-Idiopathic Normal colonic transit (psychogenic) Colonic inertia Outlet delay Dyssynergic defecation Megacolon or megarectum
Slide 19-

Etiology – Secondary Causes (further investigation)
Slide 20-

Management Education Behaviour modification Dietary changes: fluids, fiber (20-35gm/d, dietary +/- supplements) Remove offending medications where possible Oral vs. suppository vs. enema Disimpaction (chemical, manual, surgical)
Slide 21-

Laxatives Bulk forming laxatives (eg psyllium) Absorb liquid in the intestines and swell to form a soft, bulky stool. The bowel is then stimulated normally by the presence of the bulky mass. Surfactants (softeners) (eg docusate) Encourage BMs by helping liquids mix into the stool and prevent dry, hard stool masses. Lubricants (mineral oil) Encourage BMs by coating the bowel and the stool mass with a waterproof film which keeps moisture in the stool. The stool remains soft and its passage is made easier. Osmotic agents (eg PEG 3350, lactulose, Mg, glycerin) Encourage BMs by drawing water into the bowel from surrounding body tissues. This provides a soft stool mass and increased bowel action. Stimulant laxatives (eg senna, bisacodyl) Increase the muscle contractions that move along the stool mass. Other (eg. Relistor)
Slide 22-

Dyspepsia Rome III criteria: >=1 of the following: Postprandial fullness Early satiation (inability to finish a normal sized meal) Epigastric pain or burning Differential: PUD, GERD, biliary, abdominal wall, malignancy, gastroparesis, pancreatitis, medications and substances, metabolic, ischemia, systemic (DM, thyroid, CTD)
Slide 23-

Red Flags (need for endoscopy) Symptom onset after age 50 (esp if male, Caucasian, smoker, >10 yrs symptoms re: Barrett’s) GI blood loss/anemia Weight loss Early satiety Dysphagia Persistent vomiting or symptoms refractory to standard therapy
Slide 24-

Investigation and Management Identify and eliminate aggravating factors (etoh, tobacco, ASA/NSAIDs, steroids, stress) Patient education re: diet and lifestyle factors Bloodwork (?H. pylori [vs urea breath or fecal antigen], ?celiac), imaging (double contrast UGI), endoscopy Treatment (PUD/GERD): H2RA, PPI, H. pylori eradication when positive
Slide 25-

Rectal Bleeding Melena vs. BRBPR Differential of BRBPR: hemorrhoids, anal fissures, polyps, proctitis, rectal ulcers, malignancy Red flags: new pain or change in nature of chronic pain, pain awakening at night, altered bowel function (frequency, caliber or consistency), constitutional symptoms, anemia, palpable lymphadenopathy, personal or family hx bowel disease
Slide 26-

Colon Cancer Check Screening Recommendations Average risk: recommend FIT q2 years for asymptomatic people 50-74 without a family hx of colorectal cancer. [Abnormal FIT: c-scope within 8 weeks]. Ages 50-74 without a family hx of colorectal cancer who choose to be screened with flex sigmoidoscopy should be screened q10 years. Increased risk: asymptomatic people get screened with c-scope if a family hx of colorectal cancer (1 or more first-degree relatives) beginning at 50 or 10 years earlier than the age their relative was diagnosed, whichever occurs first.
