1 Hernia: Laparoscopic vs. Open Repair Michael R. Renfrow M.D., F.A.C.S. Clinical Assistant Professor, Dept. of Surgery, Florida International University Objectives Examine the anatomy and pathophysiology of a hernia Identify patients who are candidates for surgical intervention Evaluate current and emerging surgical options (open, laparoscopic, robotic) for patients with a hernia Hernia Abdominal wall composed of: -skin -subcutaneous tissue (fat) -muscle -fascia (hernia is a hole in the fascial layer) -peritoneum (hernia sac) A hernia is defined as sac formed by the lining of the abdominal cavity. The sac comes through a hole or weak area in the strong layer of the abdominal wall called the fascia. 1

5 Risk Factors Increased intra-abdominal pressure Obesity COPD Heavy lifting Tobacco/Smoking Genetic (Collagen) Previous abdominal surgery (Incisional hernia) Signs and Symptoms Pain (dull, worse on exertion) Bulge or mass Differential Dx Hernia Lymph Node (Reactive, Metastatic, Lymphoma) Soft tissue tumor (Lipoma, Sarcoma) Vascular (tumor, anuerysm) Cyst Desmoid, Endometrioma (female patient, hx of a gynecologic surgery, close to the scar) Hydroceale/Varicoceale Testicular Torsion Testicular Tumor 5

6 Diagnostic Imaging Ultrasound (Dynamic with Valsalva) CT scan MRI 6

7 Management Observation (Abdominal binder) Surgical Repair -Laparoscopic vs Open -Mesh Principles of Hernia Surgery Safely reduce hernia content (bowel, omentum, etc ) Excise hernia sac Close fascial defect Minimize tension on the repair Reinforce with mesh when indicated 7

8 Laparoscopic vs Open Hernia Surgery Which repair is better? What are the differences between the two? Laparoscopic vs Open Approach Open Anterior approach Traditional incision Laparoscopic Posterior approach Multiple small incisions Open Comparing Surgical Technique Open Repair is an anterior approach Laparoscopic Repair is a posterior approach 8

12 Inguinal Hernia Laparoscopic vs. open No significant difference in recurrance rate Data suggests less pain and numbness in laparoscopic repair Return to usual activities is faster in laparoscopic repair Operative times are longer with laparoscopic Higher risk of serious complication with laparoscopic approach, in particular bladder and vascular injury Cocharane Database Syst Rev 2003(1) Ventral/Incisional Hernia Laparoscopic vs. Open No difference in recurrence rate Reduced risk of wound infection in laparoscopic Shortened hospital stay Lower 30-day morbidity in laparoscopically repaired strangulated & recurrent hernias (4.7%vs8.1%) No difference in pain intensity -Cochrane Database Syst Rev 2011 Mar 16(3) -Ann Surg 2011 Oct;254(4):

13 Paraesophageal & Hiatal Hernia Protrusion (or herniation) of the upper part of the stomach into the posterior mediastinum via a disruption of the esophageal hiatus of the diaphragm Symptoms: Heartburn, Chest pain, Cough Management: Medical management (PPI) Surgery (Open, Laparoscopic, Robotic) 13
