Hernioplasty
80
Onlay repair
If mesh is kept above the rectus sheath
between skin, subcutaneous tissue and anterior rectus sheath.

83
• Preperitoneal/ sublay repair
If the mesh is kept between the peritoneum and sheath.
84
Intraperitoneal repair
Called as IPOM /Intraperitoneal placement of mesh. used in laparoscopic repair. To prevent fecal fistula and adhesion (bowel-mesh adherance) PTFE meshes are used.
85
IPOM Procedure
ventral hernia defect is dissected -> content of the hernia (preperitoneal fat globule) is pulled down -> defect visualized -> mesh placed after adequate dissection -> Covering atleast 4-5cm across the defect -> to avoid mesh shrinkage. mesh is anchored to the abdominal wall using tackers or staplers to prevent movement of mesh.
86
What is remirez component separation technique
Done in complex incisional hernias . where incisional hernia volume is >25% of abdominal volume
87

91
High rate of obstruction and strangulation seen in which kind of hernia
Paraumbilical hernia
92
Which hernia is more common in premature babies
Umbilical hernia
93
Management of umbilical hernia in children
Conservative management wait for 2 to 3 years of age if defect does not close by itself do mesh repair surgery after 2 to 3 years
94
Management of paraumbilical hernia
Open laparoscopic hernioplasty
95
What is omphalocele
Defect through the umbilicus in which bowel fails to return inside during embryogenesis, covered with peritoneal sac. Liver can also herniate .
96
Omphalocele is associated with
Associated with Beckwith weidmann syndrome (wilms tumor), trisomy 13, 18, 21.
97
Management of omphalocele and gastroschisis
management is done after ruling out other congenital abnormalities.
Pushing bowel inside the abdomen can cause abdominal compartment syndrome.
Silo/cylinder is created using mesh -> defect covered
Child reviewed periodically -> reduce the height of silo -> gradually push bowel into abdomen across multiple visits.
Once it reaches the level of rectus sheath, the contents are pushed inside and abdomen is closed..
98

103
spigelian hernia / Intra-parietal hernia comes out through
It comes out through spigelian fascia (modification of fascia tranversalis).
104
MC location of Spigelian hernia / Intra-parietal hernia
Below the umbilicus but above the arcuate line (midpoint between umbilicus and pubic symphysis) along the outer border of rectus.
Below the arcuate line, posterior rectus sheath is absent.
105
What is Intraparietal hemia
Sac lies at the outer border of rectus and in between the muscle layers (invisible). usually detected when obstruction or strangulation occurs.
It is a small defect in young children, whereas in adults it is large defect.
106
What is obturator hernia / french hernia
Little old lady's hernia.
common in elderly, multiparous woman.
It comes out through narrow defect/obturator canal, hence prone to obstruction and strangulation.
They can also develop Richter's hernia
107
What is Howship Romberg sign.
Shooting pain along obturator nerve during abduction and medial rotation of hip.
108
What is Hannington Kiff sign
Absent adductor reflex in "the presence of a positive patellar reflex because of obturator nerve compression. Swelling is usually not felt, and so diagnosed late.
109
What is Ritchter’s hernia
There is a very narrow defect resulting in herniation of only a portion of bowel wall, while the rest of the bowel lumen continuity is maintained -> no features of obstruction like vomiting/distension/obstipation-> vigorous bowel contractions -> early presentation is gastroenteritis -> peritonitis/ strangulation.
110
Hernias with narrow defect can give rise to Richter's hernia. They are
• Femoral hemia.
• Paraumbilical hernia.
• Obturator hernia.
Early repair is mandated in thse hernias.
111
What is Maydl’s hernia
Defect is very wide, multiple loops of bowel can go through causing a W' shaped hernia.
If strangulation is to occur, it occurs in the intraperitoneal portion.
Significance: Intra-abdominal strangulation may be missed as normal bowel is seen upon incision.

Transverse colon usually herniates.
115
Most common cause of death in CDH patient

121
What is Peterson's hernia
Behind the roux limb after sure
122
What is Left paraduodenal hernia
Through fossa of Landzert, due to defective fusion of descending colon mesentery. As descending colon is supplied by inferiormesenteric vessels, the hernia lies behind the inferior mesenteric vessels.
123
What is Right duodenojejunal hernia
: This is due to defective fusion of ascending colon mesentery. As ascending colon is supplied by superior mesenteric vessels, the hernia lies behind the superior mesenteric vessels.
124
