Study Notes
Implanted Materials Live Session
- Alison Livesey, October 2024
Case Study 1: George the Labrador
- One-year-old male
- Vomiting for one week
- Has not eaten anything in a week
- Frequently eats stones
- Admitted for radiographs showing a foreign body in the intestines
- Suspected exploratory laparotomy due to sharp object and potential perforation
- To be stabilized and taken to surgery following stabilization.
Suture Materials and Considerations
- Suitability of suture materials for enterotomy/enterectomy
- Neighbor- absorbable? Non-absorbable?
- Needle type and size
- Suture pattern (monofilament/multifilament)
Prolene-Polypropylene
- Synthetic material, non-absorbable
- Long-term strength retention
- Poor handling, high memory
- Not suitable for intestinal repair
- Reverse cutting needle not suitable
Vicryl/Polyglactin 910
- Synthetic braided/multifilament material, absorbable
- Absorption time: 56-70 days
- Loss of strength occurs over the time period of absorption
- Used for ligation/tissue approximation
- Braided structure is more likely to wick bacteria
- Reverse cutting needle not suitable
Chromic Cat Gut
- Natural material/absorbable
- From cattle/sheep mucosa & submucosa
- Excellent handling, but can elicit a foreign body reaction.
- Loss of strength occurs over the time period of absorption
- Full absorption occurs in 42 days
- Loses strength more rapidly if infection is present
- Not suitable for intestinal anastomosis
- Swaged needle needed for anastomosis
PDS Polydioxanone
- Synthetic absorbable monofilament
- Less wicking than multifilament
- High memory
- Useful where prolonged support required
- Predictable absorption time: 180 days
- 14-20% loss at 14 days, 41%-50% loss at 42 days, 86% loss at 56 days
- Round-bodied needle
Needle Evaluation
- Problematic needle examples shown on slides
- Requirements for proper needle shape and fixation (swaged needle)
Suture Patterns for Enterotomy/Enterectomy
- Simple interrupted or continuous patterns suitable for enterotomy/enterectomy.
Patient Considerations for Surgery
- Hypovolemia
- Hypoproteinaemia
- Hypothermia
- Break in asepsis
- Contaminated procedure and spillage
- Analgesia
- Halsted's principles (aseptic technique, preserving blood supply, minimized tension, accurate tissue apposition, minimized dead space, haemostasis)
Surgery on George
- Removal of sharp pebble (foreign body) and successful end-to-end resection performed.
Wound Classification
- Categories include clean, contaminated, and dirty. Different wound classifications.
Case Study 2: Two-year-old Female DSH Cat with Suture Issue
- Owner noted suture hanging from wound following midline spay.
- Simple continuous pattern was used in the linea alba during prior surgery.
- Potential patient factors (immune system, hydration, co-morbidities)
- Potential surgical factors influencing suture failure (wrong size/type of material, incorrect suture pattern, improper placement).
- Cat had fluid in the abdomen, suggesting another underlying cause for the issue.
Case Study 3: Three-year-old MN Shih Tzu
- Grade 3 patellar luxation surgery 4 weeks prior.
- Tibial tuberosity transposition.
- Swelling developed over stifle following the operation.
- Corrective measures needed.
Case Study 4: Four-year-old FN DSH Cat
- Urinary straining, hematuria, and presence of calcium oxalatecrystals.
- Radiographs reveal calculus in the bladder.
- Cystotomy procedures
Suture Material for Cystotomy
- Stay sutures to suspend the bladder and prevent abdominal contamination.
- Synthetic absorbable material (polydioxanone/polyglactin) 25/3/0 or 4/0 (1.5/2 metric).
- Two-layer closure recommended if possible.
- Inverting suture for water-tight closure.
Inverting Suture Patterns
- Lembert
- Connell
- Cushing
- Detailed techniques illustrated on images.
Polyglactin 25 (Monocryl) Sutures
- Synthetic absorbable
- Monofilament
- Rapid absorption: 91-119 days.
- Quicker loss of strength than polydioxanone.
- 30-50% strength loss at 7 days.
- Knot security less reliable than multifilaments.

- Important properties and considerations regarding suture selection.
Size Guides
- Conversion between metric and USP sutures
