There are three techniques
1- Intra peritoneal only mesh ( IPOM )
2- Trans abdominal pre peritoneal ( TAPP )
3- Totally extra peritoneal ( TEP )
In all techniques, three trocars are used.
3
IPOM TECHNIQUE
4
-
One from umbilicus
-
Other two trocars , lateral to rectus muscles
-
Mesh is placed to overlap the defect
-
Fixed with tacks, sutures or combination
-
It is not used in routine practice
TAPP TECHNIQUE
5
-
Trocar sites are same for IPOM
-
Periton is incised 2 cm above to hernia defect at the
medial umbilical ligament and peritoneal flaps are
created
-
Dissection of hernia sac
-
Placement of mesh
-
Closure of peritoneum
-
In TAPP and TEP, dissection area and mesh placement
area the same. Difference is “ to approach to the pre
peritoneal area”
TEP TECHNIQUE
Trocar position : There are two techniques
1.
-
Umbilicus ( 10 mm )
-
Above the pubic arch ( 5 mm )
-
Midway between two trocars ( 5 mm)
2.
-
Umbilicus ( 10 mm )
-
Above the pubic arch ( 5 mm )
-
Medial to anterior superior iliac spine or the side of hernia (5 mm )
6
TEP –CONT.
A- First trocar is applied in a plane between posterior surface of
rectus muscle and posterior rectus sheath and peritoneum with
balloon – preperitoneal retzius area are dissected
B- Second and third trocars are inserted
C1- First landmark is pubic bone and Cooper ligament
2- Medially direct hernia reduction
3- Laterally indirect hernia sac: superio-laterally from
spermatic vessels. Medially vas deferens is dissected.
7
TEP CONT.
-
Cord parietalization to a point that crosses iliac vessels
Preperitoneal dissection should be so big that “ When
preperitoneal area is closed, prosthesis should lie flat in the
preperitoneal space and should not roll up.”
D- Placement of mesh ( 12 x 15 cm polypropilen, polyester from
umbilical port )
E- Fixation with tacks, staples, biologic glue. Fixation should be
applied superior to iliopectineal ligament.

IN GENERAL
IPOM
Advantages
-Minimal dissection
-Minimal postoperative pain
Disadvantages
-Risk of bowel injury
-Adhesive complications or herniations
9
TAPP
Advantages
-
Easier to learn, anatomy is more familiar for the
surgen.
-
The work space is larger than TEP
-
Allows to see the hernia sac contents
Disadvantages
10
-
Potential intra abdominal injury risk
-
More time consuming than TEP
-
Potential adhesive complication at where peritoneum
has been closed
TEP
ADVANTAGES
-reduced risk of potential intra abdominal injury
-reduced risk of adhesive complications
-operation time is less than TAPP
DISADVANTAGES
-learning curve is longer than TAPP
-the working space is limited
- inadvertently peritoneum can be torn.
11
CASE SELECTION
TAPP preference
-
Recurrence after TEP
-
Patients in who had radical prostatectomy operation
-
Patients who has midline incision for major surgery
-
In the absence of this two conditions TEP is preferred
technique.
12
LAPAROSCOPY CONTRINDICATIONS
Absolute
-
Infection
-
Coagulopathy
-
In whom general anesthesia has increased risk
Relative
13
-
Previous surgery in Retzius space
-
Incarcerated sliding scrotal hernia
