Introduction
•One of the leading cause of death and disability.
•Identification of serious intra-abdominal injuries
is often challenging.
•Peak incidence of abdominal trauma is 15-30
years.
•Injury accounts for 15-20% of all trauma deaths.
•Uncontrolled haemorrhage - major cause of
death immediately after abdominal trauma.
•Most common delayed cause of mortality and
morbidity following abdominal trauma is sepsis.
Pre-hospital care
•Goal – deliver the patient to hospital for
definitive care as soon as possible.
Scoop and Run
•ABC & care of spinal cord
•Start IV line
•Communicate to medical control
•Rapid transport of patient to trauma centre
Primary Survey (ATLS protocol)
•Airway with cervical spine protection
•Breathing and ventilation
•Circulation with hemorrhage control
•Disability : neurologic status
•Exposure/Environment control
Secondary Survey (ATLS protocol)
•Head to toe evaluation
•Complete history and physical examination
•Reassessment of all vital signs
•Complete neurological examination
•Indicated x-rays are obtained
•Special procedures
•Tubes and fingers in every orifice
Secondary Survey (ATLS protocol)
AMPLE history
•Allergies
•Medications
•Past illness/Pregnancy
•Last meal
•Events/Environment related to injury
Solid Visceral Injury
•Splenic Injury
–most common (40-55%)
–20% occur due to left lower rib fracture
•Liver Injury
–2
nd
most common (35-45%)
–50% liver injury stop bleeding spontaneously by
the time of surgery
–Mortality 10%
Clinical Feature -Abdominal Injury
Gastrointestinal Injuries
•Incidence – 1-12%
•Perforation of stomach, small bowel and
colon.
•Gastric injuries cause chemical irritation.
•Small bowel and colonic injuries cause
suppurative peritonitis.
•Inflammation may take 6-7 hours to develop.
Clinical Feature - Abdominal Injury
Retroperitoneal Injuries
•Pancreatic Injuries
•4% of patient with abdominal trauma.
•No specific signs and symptoms.
•Mechanism of injury – rapid deceleration
•Duodenal injuries
•Relatively asymptomatic on presentation – small
hematomas may go undiagnosed.
•Gastric outlet obstruction
•Duodenal rupture – high velocity deceleration
Clinical Feature - Abdominal Injury
•Kidney injuries
– 10% patients with abdominal trauma
–Injuries consist of lacerations, avulsions and
hematomas to the kidney itself and renal pelvis
–Renal vascular injuries are uncommon
Renal Injury Scale
Grade Description
I Hematuria with normal anatomic studies (contusion) or subcapsular,
nonexpanding hematoma; no laceration
II Perirenal, nonexpanding hematoma or <1 cm renal cortex laceration
with no urinary extravasation
III >1 cm renal cortex laceration with no collecting system involvement
or urinary extravasation
IV Laceration through cortex and medulla and into collecting system or
segmental renal artery or vein injury with hematoma
V Shattered kidney or vascular injury to renal pedicle or avulsed
kidney
Clinical Feature - Abdominal Injury
•Ureteral Injury
–Isolated urethral injury is rare in trauma
–Penetrating trauma – 90% & blunt trauma 10%
–70% cases will have gross or microscopic
hematuria
Clinical Feature - Abdominal Injury
•Bladder Injury
–2% of blunt abdominal trauma
–70-97% associated with pelvic fracture
–Lower abdominal pain, tenderness and gross
hematuria
–Lower abdominal bruising, abdominal swelling from
urinary ascites, perineal or scrotal edema from
urinary extravasation, and inability to void
–secondary to penetrating trauma - injuries to the
rectum or buttocks.
Clinical Feature - Abdominal Injury
Urethral Injury – Anatomical Classification
•Posterior urethral injuries
–Major blunt force trauma- rapid deceleration
mechanism
–Triad of urinary retention, blood at the meatus
and high riding prostate.
–10% of patients with pelvic fractures.
•Anterior urethral injuries
–Direct perineal trauma – blunt / penetrating
–Straddle injury is classic mechanism
–Can also occur with penile fracture
Clinical Feature - Abdominal Injury
Diaphragmatic Injuries
•Diaphragm spasm – secondary to direct blow
to epigastrium.
•Diaphragmatic rupture – penetrating trauma
or blunt force mechanism.
•Failure to diagnose – delayed herniation or
strangulation hernia of abdominal contents.
Diagnosis
Abdominal injuries that need expanded evaluation
Prasence of pain, tenderness, distention and external signs of trauma
Mechanism of injury with a high likelihood of causing abdominal injury
Suspicious lower chest, back or pelvic injury.
Inability to tolerate of delayed diagnosis
Presence of distracting injuries
Altered consciousness/sensorium
X-ray Chest/Abdomen

CT SCAN
CT Scan – Normal Abdomen
CT Scan – liver injury involving
majority of right lobe
CT Scan – Liver laceration
CT Scan – Pancreas Injury
CT Scan – Splenic injury
CT shows a subcapsular hematoma with a splenic laceration extending from
the capsule to the hilum with an intraparenchymal hematoma (blue arrow)
CT Scan – Splenic injury
This CT shows Rupture of the anterior half of the spleen caused by blunt
trauma.Haemorrhage is seen within the splenic bed (arrow)
CT Scan – Kidney injury
Left kidney multiple lacerations
CECT Scan – Ureter injury
Right ureteric injury from penetrating rauma
Diagnosis in penetrating trauma
•USG – FAST
•CT SCAN
•DPL
•Local exploration
CT Scan Abdomen -evidence of bullet in intra-
abdominal (intrahepatic) topography

Ant. Abdominal wall injury with
hypotension
Injury to abdomen, back and flank with
hypotension
Abdominal wall disruption Abdominal tenderness
Peritonitis GI evisceration
Free air under diaphragm on cxrHigh suspicion of trans abdominal
trajectory after gunshot wound
Positive FAST/DPL in hemodynamically
unstable patient

Relative
Positive FAST/DPL in hemodynamically
stable patient
Positive local wound exploration after
stab wound.
Solid visceral injury in stable patient
Hemoperitoneum on CT without clear
source
Non-operative management of blunt
trauma
•Patient hemodynamically stable after initial
resuscitation.
•Continious patient monitoring for 48 hrs
•Surgical team immediately available.
•Adequate ICU support and transfusion
services available.
•Absence of peritonitis.
•Normal sensorium.
•Angioembolization may be an alternative to
surgery
