ACUTE SURGICAL CONDITIONS Daniel J. Farrugia, MD PhD University of Florida, Department of SurgeryJune 24, 2014 New Resident Orientation
Pancreaticobiliary Service Acute cholecystitis Acute cholangitis Acute pancreatitis
Acute Cholecystitis Low grade fever, RUQ pain, oral intolerance Mild leukocytosis: 10-12 Key points RUQ US best test – stones, pericholecystic fluid, GB wall thickening >3 mm, CBD >6 mm Complicating features: diabetes, peritonitis, high leukocytosis, high-grade fever, jaundice/hyperbilirubinemia. Could indicate gangrenous cholecystitis, perforated cholecystitis, choledocholithiasis, cholangitis, pancreatitis.
Cholangitis Fever and leukocytosis Charcot’s Triad/Reynold’s Pentad Rapid progression to sepsis. Hyperbilirubinemia, dilated common bile duct Imaging: only indicated if diagnosis is not certain. No role for MRCP in clear-cut cholangitis. Treatment: emergent ERCP for stone extraction and sphincterotomy.
Acute Pancreatitis Acute onset epigastric pain radiating to the back Elevated amylase and lipase Possibly elevated transaminase and alk phos from impacted gallstone Common causes: alcohol, gallstone, metabolic, malignancy, drugs, hypertriglyceridemia Treatment depends on the underlying cause, supportive care
Acute Care Surgery/VA General Appendicitis Small bowel obstruction Incarcerated hernia Perforated gastric ulcer
Acute Appendicitis History and physical are the most important Acute onset peri-umbilical pain migrating to the right lower quadrant. Nausea and vomiting, subjective fevers, chills. Pain at McBurney’s point, peritonitis. Signs: Rovsing, Psoas, Obturator Imaging: CT with IV contrast is first line, ultrasound in children and pregnant women, MRI CT: enlarged appendix greater than 6 mm, contrast enhancement of the appendiceal wall, non-filling of appendix lumen with oral contrast, peri- appendiceal fat stranding Management: IV fluids, IV antibiotics (Unasyn or Cipro/Flagyl in adults, Ceftriaxone/Flagyl in pediatrics) Laparoscopic appendectomy in most cases Additional points: high fever or high leukocytosis often correlates with perforation.
CT of appendicitis
Small Bowel Obstruction Absence of flatus, bowel movements Nausea, vomiting, abdominal distention, abdominal pain CT scan Look for proximal dilatation, distal decompression, “transition point” Closed loop, Free fluid, mesenteric swirling Small bowel protocol after overnight decompression Most common cause are adhesions and hernias. History must include documentation of prior abdominal or pelvic surgeries. Must rule out incarcerated hernias, volvulus. Treatment for small bowel obstruction caused by adhesions is initial conservative management with NPO, NG tube, IV fluids.
Dilated promixal / Decompressed Distal
Incarcerated Hernias Reducible, incarcerated, strangulated Inguinal, umbilical, femoral, obturator, ventral. Femoral and operator hernias are difficult to diagnose on physical exam. CT scan is helpful Do not reduce a hernia in someone who is toxic Maneuvers to increase successful reduction Supine position, legs bent, deep constant pressure, Trendelenburg position, sedation Acutely irreducible hernia is an indication for surgery.
Inguinal hernia imaging
Perforated Gastric Ulcer Acute onset abdominal pain Peritonitis, rigid abdomen Free air under diaphragm on erect CXR or KUB H/o aspirin, NSAIDs, Goody powder Treatment: urgent laparotomy.
Air under the diaphragm
Treatment of Gastric Ulcer
Vascular and TCV Surgery Acute limb ischemia DVT/PE Ruptured AAA Acute dissection
Acute Limb Ischemia 6 Ps: pain, pulselessness, paralysis, pallor, paraesthesia, poikilothermia Obtain history about timing, irregular heart rhythm, chest pain suggestive of heart attack, history of aneurysms. Document good pulse exam Treatment: immediate anticoagulation with heparin infusion Embolectomy Fasciotomy Possible muscle weakness and sensory loss, inaudible arterial signal with intact venous signal
DVT Unilateral leg swelling, leg pain, worse with movement Homan’s sign is not useful Wells criteria Diagnosis: venous duplex ultrasound D-dimer is usually elevated postoperatively Rx: systemic anti-coagulation with therapeutic heparin GTT or Lovenox SQ
Pulmonary Embolism Tachypnea, tachycardia, pleuritic chest pain Assess for DVT CXR and EKG nonspecific (rule out other stuff) ABG: decreased CO2 (tachypnea) Radiology: PE protocol CT is expensive, requires heavy dye load, and is not appropriate for low suspicion V/Q scan, like all nuc med studies, are of limited value Same Rx as DVT Supplemental O2
Ruptured AAA Signs of shock Pulsatile abdominal mass Most common presentation is transfer from OSH with CT scan showing AAA rupture Call fellow on call immediately If stable, obtain CT scan for possible endovascular repair planning if not already done Operative & Blood Consent, T+C, Labs OR
Aortic Dissection Sudden onset tearing, ripping, 10/10 chest pain radiating to back Vitals: hypertension Work up: CT, Echo Treatment: beta blockers and BP control for Type B OR for type A
Aortic Dissection Stanford A/B: A = asc, B = arch + desc DeBakey I, II, III I asc + desc II asc + arch III desc distal to L SCA Determine LocationClassification
Colorectal Surgery Acute Diverticulitis Perforated Colon Cancer
Diverticulitis LLQ pain, hx of diverticulosis, past episodes Diagnosis by CT scan Uncomplicated – bowel thickening, localized tenderness Complicated – Hinchey Classification Hinchey I: pericolic abscess Hinchey II: larger mesenteric abscess, extension to pelvis Hinchey III: free perforation, purulent peritonitis Hinchey IV: feculent peritonitis Treatment: uncomplicated clear liquids, oral abx, ?outpatient management complicated Hinchey I/II: NPO, IV abx, percutaneous drainage for abscess >5cm Hinchey III: resection and primary anastomosis vs colostomy Hinchey IV: diverting colostomy
Burn Surgery Burns Necrotizing soft tissue infection
Burn Mechanism gas on trash, explosion, house fire, electrical, chemical Rule out inhalational injury History: enclosed space, smoke Physical: soot in mouth, singed facial hairs, hoarseness Labs: methemoglobin on ABG Bronchoscopy Resuscitate – Parkland Formula, LR, UOP Evaluate pulses for need for escharotomy / fasciotomy
Necrotizing soft tissue infection Risk factors: Diabetes, Immunosuppression Exam: tachycardia / tachypnea / altered mental status Tenderness / pain away from erythematous area Crepitus, paralysis, bullae Labs: LRINEC score Imaging: CT for gas in soft tissue / fascia MRI difficult to obtain quickly Diagnosis is CLINICAL Treatment: Urgent wide debridement IV Abx: Vancomycin, Zosyn, Clindamycin
Gastroschisis / Omphalocele Gastroschisis Defect of umbilical membrane near vein No coverage Need immediate coverage Omphalocele Incomplete closure of abdominal wall Associated with other abnormalities (VACTERL) Babygram (vertebral) Echocardiogram Usually covered by sac, sometimes ruptured
Midgut Volvulus Secondary to intestinal malrotation Bilious emesis Xray: gastric/duodenal distension UGI: oral contrast film corkscrew appearance of duodenum extrinsic compression by Ladd’s bands Small bowel on right, colon on left Duplex US: SMV is normally to right of SMA, flipped in volvulus
Intussusception Age 6 months to 2 years Hypertrophied Peyer’s patches Colicky abdominal pain, currant jelly stool Tx: air enema by radiology Operative reduction if enema unsuccessful
Pyloric Stenosis Risk factors: first born white male, erythromycin use in pregnancy Age: 2-6 weeks History: nonbilious projective vomiting shortly after feeds Physical: palpable “olive” epigastric area Labs: hypokalemic hypochloremic metabolic alkalosis Imaging: abdominal ultrasound Tx: resuscitation, correct electrolytes Operation only after medical stabilization
Necrotizing Enterocolitis Abdominal distension, intolerance to feeds, bilious emesis, bloody stools soon after enteral intake in premature infant Abdominal erythema, crepitus, or discoloration is ominous Tx: NPO, IV abx, NGT, resuscitation Urgent operation for: Pneumoperitoneum Portal venous gas, abd erythema, clinical deterioration
