INTRODUCTION: Incidence <10% all Trauma Abdominal injuries occur in 1/3 of patients with Severe Trauma Most common injuries affect: Liver, Spleen, Kidneys Mortality in up to 20% of trauma laparotomy Mechanism: Blunt or Penetrating Abdo assessed in Circulation in ATLS Primary survey Abdominal & pelvic injuries may be missed/ unrecognized ETOH/ intoxication, brain or spine injury, adjacent injuries (chest), retroperitoneal injury Significant blood loss w/o external signs
ANATOMY:
MECHANISMS OF INJURY:
ASSESSMENT:
EMERGENCY RESUSCITATION: IV Fluids- 1L Bolus crystalloid Blood transfusion – if unresponsive to IVI Control external bleeding Dressing wounds & eviscerated organs High-flow O 2 Patient warming Analgesia Immobilization/ pelvic binding Antibiotics *Tranexamic acid
Hx:
PHYSICAL EXAM:
CLINICAL SIGNS: Seat Belt sign: Bruising or ecchymosis around skin on seatbelt distribution Intra-abdominal injury- bowel, mesentery, solid organs Cullen’s sign: Bluish discolouration around umbilicus Blood in periumbilical tissues or falciform Hemoperitoneum, Retroperitoneal bleed, *severe pancreatitis Grey-turner’s sign: Bluish discolouration in flanks Retroperitoneal hematoma/ *hemorrhagic pancreatitis Kehr’s sign: Referred pain to Lt shoulder – diaphragmatic/ phrenic irritation (C3-5) Splenic rupture, Pneumoperitoneum, hemoperitoneum Balance sign: Dullness on percussion of LUQ Ruptured spleen
ADJUNCTS: Gastric tube insertion Urinary catheter FAST- *risk of false negative, >100mls blood/fluid CXR: exclude hemo /pneumothorax in penetrating injury above umbilicus, air under diaphragm CT scan
MANAGEMENT: Non-operative management Serial physical examination – 94% accuracy Serial Hct / Hb CT-scan IR – Liver, spleen, pelvis (contraindicated in hemodynamically unstable) Diagnostic laparoscopy Laparotomy: Blunt abd trauma + hypotension + evidence of intraperitoneal bleeding Penetrating abd trauma + hypotension/ or GI or GU tract bleeding Gunshot to abd Evisceration Peritonitis CT evidence of injury needing surgical intervention
GOAL OF LAPAROTOMY: Damage control surgery: Focus on restoration of physiology/ function Trauma triad of death: hypothermia, acidosis, coagulopathy Deferred definitive treatment Temporary abd closure Haemorrhage control Contamination control Definitive treatment + Anatomical repair
PELVIC INJURY: Hypotension + pelvic injury assoc with high mortality (upto 42%) Pelvic fracture: AP Compression Lateral Compression Vertical Shear Management: Hemorrhage control Fluid/ Blood resuscitation Pelvic stabilization - binders
CASE 1: B4521161 55M TRAUMA CALL TO ED Ambulance referral with self stab to abdomen Found covered in blood waist down, knife 4-5 cm long, 3cm laceration Bleeding had stopped Obs: A- clear, B- elevated RR, Sats-95%, C- HR -98, weak radial pulse, BP-67/37, CR 4sec D- GCS-14 Done: Bilat cannulation, fluids (saline), Tranexamic 1gm, O2-100% nasal cannula, , Bloods: Hb-134 (150s), Plt-375, Hct-0.41, Cr-256, Ur-7.7, eGFR-23 (>90)

CT IMAGES:
CT-ABD PELVIS: Conclusion: 1. Superficial penetrating injury supraumbilical abdominal wall. 2. No significant intra-abdominal trauma evident. 3. Incidental right renal cortical mass, suspicious of a T1b RCC. 4. No regional nodal or metastatic disease. 5. Small left lower pole renal calculus. 6. Minor basal atelectasis. 7. Small periumbilical abdominal wall hernia. -Suggest urology referral in due course.
CASE 2: G338175 97M Unwitnessed fall, long lie, coffee ground vomitus on side SH: care home, dementia, AF (on DOAC) Obs: R-18, Sat-98%, P-63, CR <2Sec, BP-113/ 62 (86/60), HR-84 irregular AF, GCS-14 Hx: Not forthcoming, some abd pain Bloods: WCC-14, Hb-142, Neu- 12.2, Leu-0.9, Lact- 5.0, CRP-12, Ur-9.0, Cr-136, eGFR-42(47)
CT IMAGES:
CT TRAUMA: Head: Old right parietal temporal infarct. Left frontal lobe hypoattenuation, more prominent than previous (CT 16/03/2024) -likely representing a matured area of infarction. No intracranial haemorrhage, new cortical infarction or mass lesion. Neck: No injury Thorax: No injury Abd/ Pelvis: Full-thickness laceration of the inferior pole of the spleen not involving the splenic hilum. Associated perisplenic haematoma extending into the left paracolic gutter.
