Venous congestion progresses to ischemia and perforation if untreated
Obstructive phase represents surgical emergency
Therapeutic Considerations
Evidence base for surgical approach
All traumatic diaphragmatic ruptures require operative repair
No level I evidence for conservative management; expert consensus mandates repair
Laparotomy preferred in acute setting (WSES position paper recommendation)
Laparotomy vs. thoracotomy approach
Acute injury: laparotomy lower rate of additional exploration (9.1% vs. 56.2%)
Delayed injury: thoracotomy preferred for adhesion management
Minimally invasive surgery evidence
Laparoscopic repair feasible in hemodynamically stable patients
Thoracoscopic repair for penetrating injury with experienced teams
Mesh vs. primary repair
Primary suture repair acceptable for small defects under 3 cm
Recurrence rate up to 42% after primary repair without mesh
Non-absorbable monofilament sutures recommended
Mesh augmentation for large or high-tension defects
Biologic mesh preferred in contaminated field
Synthetic mesh (polypropylene) for clean elective repair
Damage control considerations
Indicated when lethal triad present (hypothermia, coagulopathy, acidosis)
Temporary closure allows physiologic restoration
Definitive repair in 24-48 hours when physiology normalized
Massive transfusion and TXA reduce mortality in hemorrhagic shock
1:1:1 resuscitation ratio supported by PROPPR trial
TXA within 3 hours of injury reduces mortality (CRASH-2 trial)
Patient Discharge Instructions
copy discharge instructions
Discharge instructions for diaphragmatic rupture
You have been treated for a tear in the diaphragm, the breathing muscle separating your chest from your abdomen
This injury required surgical repair during your hospital stay
Recovery depends on your other injuries and the surgical approach used
Activity restrictions after repair
No heavy lifting (more than 5 kg) for 6-8 weeks after open repair
No strenuous activity or contact sports until cleared by your surgeon
Driving restrictions apply while on opioid pain medications
Wound care instructions
Keep surgical incision clean and dry for 48-72 hours
Steri-strips or staples: do not remove; surgeon will remove at follow-up visit
Signs of infection: redness, swelling, warmth, discharge, or fever above 38 degrees C
Breathing exercises
Use incentive spirometer 10 times every hour while awake
Deep breathing and coughing exercises prevent pneumonia after surgery
Splint incision with pillow when coughing
Return to emergency department immediately if
Worsening shortness of breath or inability to breathe lying flat
New or worsening chest pain
Fever above 38.5 degrees C
Severe abdominal pain, nausea, or vomiting (possible bowel obstruction)
Inability to pass stool or gas for more than 48-72 hours
Abdominal distension worsening
Wound concerns
Significant bleeding or discharge from wound
Wound edges opening (dehiscence)
Increasing redness or warmth around incision
Follow-up appointments
Trauma surgery clinic within 2 weeks of discharge
Chest X-ray at discharge and at 2-4 week follow-up visit
CT scan if symptoms recur or new concerns arise
Important long-term information
Recurrence of diaphragmatic hernia is possible (up to 42% without mesh)
Any episode of chest or abdominal pain months to years after discharge should prompt medical evaluation
Delayed presentation of diaphragmatic hernia can occur weeks to years after injury
