  1. Traditional Hernia Repair Basic Format Herniorrhapy

  2. Objectives • Assess the anatomy, physiology, and pathophysiology of the abdomenal wall. • Analyze the diagnostic and surgical interventions for a patient undergoing a herniorrhapy. • Plan the intraoperative course for a patient undergoing inguinal herniorrhapy. • Assemble supplies, equipment, and instrumentation needed for the procedure.

  3. Objectives • Choose the appropriate patient position • Identify the incision used for the procedure • Analyze the procedural steps for inguinal herniorrhaphy. • Describe the care of the specimen • Discuss the postoperative considerations for a patient undergoing pt w/inguinal herniorrhaphy.

  4. Terms and Definitions • Hernioplasty or herniorrhaphy • Hesselbach’s Triangle • Transversalis fascia • Reducible hernia • Incarcerated hernia • Strangulated hernia

  5. Definition/Purpose of Procedure • Definition • A sac lined by peritoneum that protrudes thru a defect n the layers of the abdominal wall; congenital, acquired, traumatic; generally covered by tissues, a peritoneal sac, and any contained viscera • Purpose • To repair the defect and strengthen the supporting structures

  6. Relevant A & P: Tissue Layers • (STST p. 404 descending order) • Skin and subcutaneous • Scarpa’s fascia • Innominate fascia • Interparietal fascia • Internal oblique muscle • Transverse abdominal muscle • Transverse fascia • Cooper’s ligament • Rectus Abdominis muscle • Peritoneum

  7. Relevant A & P: Other structures • Superficial & inferior epigastric muscles • Iliofemoral vessels • Spermatic cord and blood supply • Ilioinguinal nerve • Lacunar ligament • Inguinal ligament (Poupart) • Conjoined ligament (Falx inguinalis) • Cremaster muscle & fascia • Hesselbach’s Triangle • Femoral canal • Iliopubic tract

  8. Pathophysiology • Protrusion of an organ or part of an organ through a defect in the supporting structures which normally contain it • Transverse fascia is the man focus of groin herniation and separates the abdominal musculature from the preperitoneal fat. It is a continuation of the fascia completely containing the abdominal cavity and is inherently weak in the area of Cooper’s Ligament and the iliopubic tract, lending to inguinal herniation.

  9. Abdominal Regions Where Hernias Occur

  10. What is a Direct Hernia? • Direct • Acquired weaknesses in transversalis fascia • Location: Hesselbach’s triangle • Causes • Emerge between the deep epigastric artery and rectus abdominus muscle and protrude into the inguinal canal but not into the spermatic cord • More difficult to repair • Men

  11. Direct

  12. What is an Indirect Hernia? • Congenital or acquired weaknesses in transversalis fascia • Location: lateral to deep epigastric vessels • Protrude through inguinal ring and pass with the spermatic cord structures down the inguinal canal; may descend into the scrotum • Men

  13. What is a pantaloon hernia?

  14. Femoral

  15. Diagnostics • Exams: asked to stand and cough during physical exam: can see outpouched area; fingertip palpation –can feel edges of external ring and or abd wall. Pt most likely will have pain; may be described as burning. Compare both sides for protrusions. • Preoperative Testing: Routine CBC, ECG or chest as applicable; can employ CT, herniography, & std radiography if dx not confirmed

  16. Surgical Intervention:Special Considerations • Patient Factors • Possibly in pain • Room Set-up : Routine

  17. Surgical Intervention: Anesthesia • Method: Various: General, Spinal, Epidural, Regional w/sedation, Local • *Surgeon may ask for pt to cooperate by coughing or bearing down • Equipment

  18. Surgical Intervention: Positioning • Position during procedure • Supine w/arm boards • Supplies and equipment • Special considerations: high risk areas

  19. Surgical Intervention: Skin Prep • Method of hair removal—at least on side of hernia down to groin—ask • Anatomic perimeters—table side to table side; upper abdomen to mid thigh • Solution options—Routine (Betadine vs Hibclens)

  20. Surgical Intervention: Draping/Incision • Types of drapes: Lap Sheet • Order of draping: 4 towels & sheet • Special considerations • State/Describe incision: Anterior Groin/oblique inguinal incision

  21. Surgical Intervention: Supplies • General • Lap pack, gowns, raytex, disposamag • Specific • Suture: Various (Mayo and Ferguson taper type needles) • After the hernia repair, finer sutures will be used for other layers of tissue • Examples: 3-0 silk ties, 2-0 silk SH (GI), 3-0 silk, 0 silk (GI needle); 3-0 vicryl ; Other possible: 2-0 Prolene SH, 0 Ethibond, 4-0 Vicryl undyed • For mesh: 0 Prolene CT-1 or CT-2 • Kittners • Blades: # 10 x 2 • 35 R stapler (hold)

  22. Surgical Intervention: Supplies cont’d • Medications on field (name & purpose) • For local: Example: Xylocaine .5% w/Marcaine .25% w/epi • 20 cc syringe, 25 g needle, possibly 22 g spinal needle • Catheters & Drains: A ½ in penrose drain is used to retract spermatic cord structures

  23. Surgical Intervention: Instruments • General • Minor set • Specific • A hemostat is placed on the penrose drain before passing to the surgeon • Med debakeys • Med rt angles • Gelpies x 2

  24. Surgical Intervention: Equipment • General: Standard • Specific

  25. Procedure Highlights • 1. Layers of the abdominal wall are incised • 2. The spermatic cord is identified & dissected free • 3. The hernia sac is identified • 4. The sac is ligated and removed. • 5. Layers of the wound are closed individually.

  26. Surgical Intervention: Procedure Steps • After prep, pt is draped with groin area exposed on affected side • Incision is made over hernia site and electrocautery used for hemostasis • Surgeon incises fascia lying over the spermatic cord and retracts w/several hemostats on the edge of the incised fascia • Surgeon identifies spermatic cord and separates it from the surrounding tissue • STSR mounts moistened Penrose drain on a med clamp & passes it to the surgeon, who passes it around the spermatic cord for retraction

  27. Surgical Intervention: Procedure Steps Cont’d • Dissection continues until hernia is located • Hernia repair • Direct • Surgeon sutures transversalis fascial defect using heavy interrupted sutures as STSR initiates first closing count • Surgeon closes external oblique fascia as SRST initiates second closing count

  28. Surgical Intervention: Procedure Steps Cont’d • Hernia repair • Indirect • Surgeon dissects sac away from the spermatic cord using Metzenbaum scissors • The sac is opened & edges grasped with hemostats • Surgeon pushes contents of sac back toward the abdomen w/ a finger or a small sponge on instrument

  29. Surgical Intervention: Procedure Steps Cont’d • Surgeon ligates small sac, uses purse-string suture, or oversews to close large sac as STSR initiates first closing count • Surgeon sutures transversalis fascial defect using heavy (0, 2-0) interrupted sutures as STSR initiates second closing count.

  30. Classic Procedures • Marcy repair • Closure of inguinal ring • Bassini or Bassini-Shouldice Repair • A new inguinal canal is made by uniting the edge of the internal oblique muscle to the inguinal ligament • McVay/Lotheissen • The transverse abdominis muscle & its associated fasciae (transverse layer) are sutured to the pectineal ligament (Cooper’s ligament repair)

  31. Summary for Hernias • Dissection: Identify the structures • Repair : Reduce the hernia; Repair the defect • Closure

  32. Counts • Initial • First closing • Final closing • Sponges • Sharps • Instruments The peritoneal cavity may be entered when the hernia sac is opened—Counts must be done!

  33. Dressing • Types & sizes • 2x2 or 4x4, ½ in steri strips, Small Tegaderm • Type of tape or method of securing • May use Mastisol or Benzoin

  34. Specimen & Care • Identified as Peritoneal hernia sac (Indirect) • Handled: Routine in formalin fixative

  35. Postoperative Care • Destination • PACU • Expected prognosis (Good)

  36. Postoperative Care • Potential complications • Hemorrhage • Infection • Other: Damage to…neural and vascular structures • Recurrence • Ischemic orchitis & testicular atrophy • Loss of bowel function • Surgical wound classification: 1
