HISTORY
The origins of surgery can be traced back many
centuries. Through the ages, practitioners have used a
wide range of materials and techniques for closing
tissue……..
1650 BC – 2000’s AD
28Training
In the tenth century BC, the ant was held over
the wound until it seized the wound edges in its
jaws. It was then decapitated and the ant's death
grip kept the wound closed.
AntsAnts
29Training
Thorns
The thorn, used by African tribes to close tissue,
was passed through the skin on either side of the wound.
A strip of vegetable fibre was then wound
around the edge in a figure eight.
30Training
Sterilised Catgut
The tough membrane of sheep intestine was provided
to the surgeon pre-sterilised and required threading
through the eye of the needle before use.
31Training
Swaged On Needles
Post World War II brought the swaged-on needle. The thread fits into the
hollow end of the needle, allowing it to pass through tissue without the
double loop of thread that exists with a conventional needle, reducing
tissue trauma.

Elongation / Elasticity
Elongation: stretching of thread
-If elastic: comes back to original length
- if not: deformation occurs (thinner- longer)
Skin closure: Elasticity = Less scar
Vascular anastomosis: No elongation to keep
anastomosis closed.
Training66
Elasticity
From less to most elastic:
• Stainless steel
• Linen,Silk,Braided Synthetic absorbables,Braided polyester
• Catgut
• Absorbable monofilaments
• Polypropylene
• Polyester monofilament
• Nylon
Training67
Capillarity
Capillarity means the action by which the surface of a
liquid where it is in contact with a solid
(as in a capillary tube) is elevated or depressed
depending on the relative attraction of the molecules
of the liquid for each other and for those of the solid.
This attraction of molecules means for sutures that
liquid like blood or even bacteria may by elevated /
transported through a suture thread.
Capillarity encourages infection causing suture
sinuses and abscesses.
Training68
Capillarity and Suture material
 No capillarity:
• Stainless steel
• Monofilaments (Synth. Absor., Polyester, Polypropylene and Polyamide)
 Not likely to have capillarity:
• PGA
• Coated polyester
• Catgut
• Coated silk
 Capillarity:
• Linen
• Braided polyester

PGA and Sterilization
As PGA is susceptible to degradation from moisture
and gamma rays:
Low humidity ethylene oxide gas sterilization
procedures are used and moisture-proof packaging.
Acceleration of in vivo degradation due to gamma
irradiation has been exploited to create devices where
early fragmentation is desired.
This is how we create I-COL FAST where we
accelerate the degradation profile of the suture, by
breaking down the molecules.

Manual
Hernia is a sac lined by peritoneum that protrudes through a defect in
the layers of the abdominal wall.
Generally, a hernia mass is composed of a peritoneal sac, into which
organs or other abdominal tissues can slip.
Most hernias occur in the abdominal cavity.
Although a hernia can develop on any part of the abdominal wall.
The areas near the natural openings in the groin areas (inguinal
hernias),
below the groin (femoral hernias),
through the naval (umbilical hernias)
through old surgical incisions (incisional hernias) are the most
common.

TYPES OF HERNIA
Inguinal Hernias-
Indirect Inguinal Hernias
This occurs due to a weakness in the abdominal wall present at birth.
In men, this weakness is caused by a space that is created as the testes
and spermatic cord descend by way of the inguinal canal (a / ½ inch
canal)
Direct Inguinal Hernia
They are most common in men and usually later in life, most often
after 40, Direct inguinal hernias are due to an acquired wear and tear
in the abdominal wall.
Training 117
Training 118
Training 119
Congenital Diaphragmatic Hernia is a birth defect in which abdominal organs
protrude up into the chest cavity.
Femoral Hernia is the protrusion of abdominal fat or part of the intestines
through the abdominal muscles into the upper thigh area.
Hiatal Hernia is the protrusion of a portion of the stomach through an opening
in the diaphragm called the hiatus. Hiatal hernia is also called a hiatus hernia.
Incisional Hernia is a hernia that develops through a previous surgical
incision. This can occur anywhere on the abdomen or back.
Inguinal Hernia is the protrusion of abdominal fat or part of the intestines
through the abdominal muscles into the groin area (also called the inguinal
canal). Inguinal hernia is the most common type of hernia.
Umbilical Hernia is the protrusion of part of the intestines or abdominal lining
through the abdominal wall around the belly button. It most often occurs in
infants ages six months and younger.
ENDOSCOPIC HERNIA REPAIR
(Minimally invasive surgery )
There are two forms of Endoscopic Hernia repairs:-
Trans-Abdominal Pre-Peritoneal (TAPP), this repair
involves entry into the abdominal cavity with peritoneal
incision and dissection, Hernia reduction,
Mesh placement, and Closing Peritoneum.
In Totally Extra-Peritoneal (TEP) Hernia repair the
abdominal cavity is not entered. The working space is
created by pre-peritoneal dissection.
Mesh is placed without peritoneal incision.

a. Midline The most commonly used incision, made
longitudinally in the center of the abdomen
along the linea alba nad between the muscles.
Can provide access to all quadrants,.
i.e: Gastrectomy.
b Right or Left
Paramedian
Vertical incision, lateral and parallel to the
midline. Used for specific surgical
procedures, e.g. Splenectomy.

Posterior
Fascia
(fascia on the posterior side of the muscle sheath) where it does
exist, is included in this layer.
Note: Where extreme obesity or stress is encountered,
surgeon will place retention sutures through all layers of the
abdomen for extra security. Most often, retention sutures are
put in prior to closure of the peritoneum.
Muscle Is frequently reflected rather than cut, and therefore does not
require closure. If muscles have been transected they may be
closed separately or together with the anterior fascia.
Fascia
(anterior)
Is relied upon to re-establish postoperative abdominal wall
strength. Therefore, anterior fascia closures are of extreme
importance. Care must be taken in approximating the fascia to
insure that there is sufficient distance from the incision line to
the closure bite, otherwise the fascia may tear before it is
healed from sudden stress such as a cough.

    HISTORY The origins ofsurgery can be traced back many centuries. Through the ages, practitioners have used a wide range of materials and techniques for closing tissue…….. 1650 BC – 2000’s AD 28Training

    In the tenthcentury BC, the ant was held over the wound until it seized the wound edges in its jaws. It was then decapitated and the ant's death grip kept the wound closed. AntsAnts 29Training

    Thorns The thorn, usedby African tribes to close tissue, was passed through the skin on either side of the wound. A strip of vegetable fibre was then wound around the edge in a figure eight. 30Training

    Sterilised Catgut The toughmembrane of sheep intestine was provided to the surgeon pre-sterilised and required threading through the eye of the needle before use. 31Training

    Swaged On Needles PostWorld War II brought the swaged-on needle. The thread fits into the hollow end of the needle, allowing it to pass through tissue without the double loop of thread that exists with a conventional needle, reducing tissue trauma. 32Training

    PGA and Sterilization AsPGA is susceptible to degradation from moisture and gamma rays: Low humidity ethylene oxide gas sterilization procedures are used and moisture-proof packaging. Acceleration of in vivo degradation due to gamma irradiation has been exploited to create devices where early fragmentation is desired. This is how we create I-COL FAST where we accelerate the degradation profile of the suture, by breaking down the molecules.

    Training Training Manual Hernia is asac lined by peritoneum that protrudes through a defect in the layers of the abdominal wall. Generally, a hernia mass is composed of a peritoneal sac, into which organs or other abdominal tissues can slip. Most hernias occur in the abdominal cavity. Although a hernia can develop on any part of the abdominal wall. The areas near the natural openings in the groin areas (inguinal hernias), below the groin (femoral hernias), through the naval (umbilical hernias) through old surgical incisions (incisional hernias) are the most common.

    TYPES OF HERNIA InguinalHernias- Indirect Inguinal Hernias This occurs due to a weakness in the abdominal wall present at birth. In men, this weakness is caused by a space that is created as the testes and spermatic cord descend by way of the inguinal canal (a / ½ inch canal) Direct Inguinal Hernia They are most common in men and usually later in life, most often after 40, Direct inguinal hernias are due to an acquired wear and tear in the abdominal wall.

    Training 119 Congenital DiaphragmaticHernia is a birth defect in which abdominal organs protrude up into the chest cavity. Femoral Hernia is the protrusion of abdominal fat or part of the intestines through the abdominal muscles into the upper thigh area. Hiatal Hernia is the protrusion of a portion of the stomach through an opening in the diaphragm called the hiatus. Hiatal hernia is also called a hiatus hernia. Incisional Hernia is a hernia that develops through a previous surgical incision. This can occur anywhere on the abdomen or back. Inguinal Hernia is the protrusion of abdominal fat or part of the intestines through the abdominal muscles into the groin area (also called the inguinal canal). Inguinal hernia is the most common type of hernia. Umbilical Hernia is the protrusion of part of the intestines or abdominal lining through the abdominal wall around the belly button. It most often occurs in infants ages six months and younger.

    ENDOSCOPIC HERNIA REPAIR (Minimallyinvasive surgery ) There are two forms of Endoscopic Hernia repairs:- Trans-Abdominal Pre-Peritoneal (TAPP), this repair involves entry into the abdominal cavity with peritoneal incision and dissection, Hernia reduction, Mesh placement, and Closing Peritoneum. In Totally Extra-Peritoneal (TEP) Hernia repair the abdominal cavity is not entered. The working space is created by pre-peritoneal dissection. Mesh is placed without peritoneal incision. Training 120

    Training Training Manual Posterior Fascia (fascia on theposterior side of the muscle sheath) where it does exist, is included in this layer. Note: Where extreme obesity or stress is encountered, surgeon will place retention sutures through all layers of the abdomen for extra security. Most often, retention sutures are put in prior to closure of the peritoneum. Muscle Is frequently reflected rather than cut, and therefore does not require closure. If muscles have been transected they may be closed separately or together with the anterior fascia. Fascia (anterior) Is relied upon to re-establish postoperative abdominal wall strength. Therefore, anterior fascia closures are of extreme importance. Care must be taken in approximating the fascia to insure that there is sufficient distance from the incision line to the closure bite, otherwise the fascia may tear before it is healed from sudden stress such as a cough.

Editor's Notes

  • #27 Presentation start - confirm contents.
  • #28 Indicate approx length of time for each section. Presentation = 30 mins Knot tying practical = 20 mins Suture Vid = 40 mins Instrument tying/Suture practical = 40 mins. Evaluation forms will be issued at the end. Demonstrate delegate bag contents (highlight the knot tying manual U-L12 and sutures and wound closure U-L6). Confirm quiz sheet also included and that a certificate will be issued at end.
  • #32 Many Surgeons used Catgut previously, it was a commonly used suture. Surgeon’s liked it’s handling characteristics. it was twisted and absorbed quickly. ‘Caprosyn’ is Tyco’s synthetically developed replacement. ‘Caprosyn’ is the fastest absorbing monofilament on the market which handles like a braid.
  • #33 Sutures used in the workshop are ‘swaged’ or ‘Atraumatic’. The majority of sutures used by Surgeons are swaged. Mention ‘D-tach’ (pop-off).
  • #38 Confirm that all sutures have a ‘source’, ‘structure’ and a ‘‘fate’. It is these categories that directly affect suture selection. Every suture is either natural or synthetic. Every suture is either a monofilament or braided. Every suture is either absorbable or non-absorbable. Provide an example such as Polysorb = a synthetic, braided absorbable suture.
  • #39 Confirm that, to conclude an ideal suture material would have the following characteristics ………… ie) absorption rate of Catcut was not consistant,Silk
  • #40 Re-iterate that 5 is very thick and that 11.0 is very very fine. Indicate that brochure U-L6 (sutures and wound closure techniques) are in the delegate bag includes this scale and examples of surgery.
  • #41 The picture illustrates that a braided suture is made from many strands of material unlike the monofilament. As a result of these structures there are various advantages and disadvantages, these may affect suture selection.
  • #44 Ask if ‘capillary’ is understood, confirm. Discuss ‘memory’. During the practical a monofilament (Monosof) and a braided suture (Polysorb) is provided so that the handling advantages and disadvantages are experienced.
  • #45 Ask what the two main performance characteristics of an absorbable suture are, confirm. Explain that tensile strength retention is an indication of the strength of a suture, in the body over a period of time. Confirm that time required to support a wound will vary according to tissue type (eg skin, muscle = days. Tendon and fascia = months. Vascular prosthesis require long term wound support). Highlight the examples of strength and absorption rates for I-COL, MONOCOL & STERICRYL.
  • #46 HERE WE LOOK AT THE ABSORPTION RATES & ALSO THE TENSILE STRENGTHS IN-VIVO OF ALL THE ABSORBABLE SUTURES.
  • #47 THIS SHOWS SOME PROPERTIES OF NON-ABSORBABLE SUTURES
  • #51 Encourage questions. Reassure that all info included in the presentation is covered in UL-6 ‘Suture and wound closure techniques’ booklet provided in delegate bag.
  • #98 Needle curvature is selected according to site accessibility. Confirm commonly used curvatures in general surgery. Explain needle stick injury risk with use of straight needle.
  • #134 These are rough guides, it’s really the Surgeon’s preference and no a strict rules apply.
