Suture and Suture Patterns Flashcards
Two broad Classification of Suture Pattern
Interrupted and Continuous
6 Categories of Sutures
- Apposition Suture
- Inversion
- Eversion
- Purse-string Suture
- Relaxation/ Tension Sutures
- Miscellaneous Sutures
Each suture is a separate entity, and can be individually positioned and tightened as needed
Interrupted Suture
Knots only at the beginning and end of pattern, and is better at providing an air, and water tight closure.
Continuous suture
Anatomically opposes the edges of the incision. This also enables to have the fastest healing and gives the most cosmetic result
Appositional
Turns incision edges inward, away from surgeon. Desirable when closing hollow organs
Inverting
Turns incision edges outwards, towards surgeon. This results in delayed healing and is rarely indicated
Everting Suture pattern
Examples of Apposition Sutures
Simple continuous
Simple Interrupted
Continuous lock-stitch (Ford-interlocking)
Subcuticular
Cross mattress or Interrupted cruciate
Example of Inversion Suture
- Lambert Suture
- Jobert;s Suture
- Cushing Suture
- Connel Suture
Suture Passes through serous and muscular layers not the mucosal layer. Needle bites are at right angles/ perpendicular to suture line
Lambert suture
Same Like lambert Suture but it penetrates mucosal Also.
Jobert’s Suture
Similar to Lambert except that bite is parallel to incision line
Cushing suture
Same as cushing but needle penetrates all layers including mucosa
Connel suture
Examples for Eversion Sutures
Horizontal Mattress Suture
Vertical Mattress Suture
Suture: Applied on the hernial ring where one side of the tissue overlaps on the other side. Combination of Lambert and horizontal mattress sutures
Overlapping (Vest over Pant) suture
