At admission to labour room
Pulse rate 110 /mt, BP : 115/80 Temp : 37.20c
Vaginal examination :
Cervix 8 cm dilated . Vertex at -2
Artificial rupture of membranes - clear liquor.
Investigations at admission:
Hb: 12.9gm/dl ,WBC:10.6, P75%,L16%.
Platelet:158
After 1 hour :Fully dilated with vx at +1
Fetal heart decelerations
Vacuum extraction-male baby 4.410 Kg Apgar 7&8

After 3 hours
Abdominal pain and distension!
O/E :

No pallor,
 Pulse 118/mt. BP: 105/70,
 Temp: 37.90c
 SPO2:100% on room air,Respiratory rate:20-/mt.

Abdomen was distended with generalized
diffuse tenderness.

Investigations:
Hb: 11.6gm/dl, WBC: 17.4, P : 93%,L: 3%,
Platelet : 149

Ultrasound abdomen :
Significant amount of free fluid in hepatorenal and
lienorenal angles and in the pelvis .
Normal puerperal uterus and ovaries
Small hemangioma in the liver.

CT abdomen was planned



Abdominal pain increased in severity over
next 2 hours.
Diff.diagnosis
Ruptured uterus
other surgical emergencies
Decision for laparotomy

LAPAROTOMY –MIDLINE INCISION
◦ 500 ml turbid fluid in the peritoneal
cavity.
◦ Patches of cheesy material on the serosal
surface of all the viscera.
Uterus intact .

Normal appendix, liver, spleen, intestines

Few enlarged mesenteric nodes


Biopsy from the node and cheesy
material
Omental biopsy

Fluid for culture

Post op:
 IV ceftriaxone & metronidazole.
 Recovery was uneventful
Squamous epithelium surrounded
by acute inflammatory response.
Lanugo hair surrounded by
acute inflammatory response.
Histopathology:
◦ Peritoneal content and omentum :
VERNIX CASEOSA PERITONITIS
◦ Mesenteric lymph node
Nonspecific reactive changes


A very unusual complication
Due to inflammatory response to amniotic fluid
spilled into the maternal peritoneal cavity presenting
as acute abdomen

Only 24 cases have been reported

All are after uneventful caesarean section

3 cases had onset from the antenatal period.

Ours is the first case of VCP reported following
vaginal delivery.
Vernix caseosa:
 Cheesy white cutaneous material covering
the skin of the newborn

Sebaceous glandular secretions+ lanugo
hairs +desquamated squamous
cells.
Numerous squamous cells are present in the
amniotic fluid


Incomplete peritoneal lavage of spilled
amniotic fluid after Caesarean
Antenatal or intra partum leakage of
amniotic fluid
◦ ?? utero tubal reflux
◦ ?? unrecognized uterine perforation
Exact mechanism is unknown



Mechanical irritation by keratinised squamous
cells
(as in meconium peritonitis/ruptured keratinous
cysts)
? Hypersensitivity reaction
( in multipara or from an antenatal primary
event)
Concentration of vernix caseosa in the amniotic
fluid may have pathogenetic significance.
Acute abdomen
◦ Generalized severe abdominal pain,
◦ Pyrexia,
◦ Peritonism

Present in few days to weeks after an inciting
event.

Elevated white cell count
Inconclusive or normal imaging.

Other causes of peritonism should be excluded

Essential feature:
 White and yellow cheesy plaques within the
peritoneal cavity and on serosal surfaces in
the absence of inflamed organs

Histopathology confirms the diagnosis
Desquamated anucleate squamous cells
sorrounded by acute,chronic(granulomatous) or
mixed inflammatory infiltrate depending on the
duration of onset


Most are self limiting.
Resolves with conservative management
 post op antibiotic therapy
 adjuvant steroid therapy may be used
(mahmoudetal 1997)
Significant morbidities following the initial
diagnosis of VCP including bowel obstruction
also has been reported (stuart et al 2009)

Many cases had significant additional
procedures including cholecystectomy ,
appendectomy ,partial colectomy , total
hysterectomy and bilateral salpingectomy.
(stuartetal 2009, boothby et al1985,cummingsetal 2001,
Hertzetal1985,Mahmoudetal 1997)

Subsequent finding of normal histology in
the excised organs.

Role of preoperative CT and fine needle
aspiration cytology /guided biopsy?---( james etal2011)

not practical
Diagnostic laparoscopy with intraoperative
pathological examination is suggested
(Bailey etal2012)

Vernix Caseosa peritonitis is an infrequent cause
of puerperal peritonitis

Can occur even after vaginal delivery as the
inciting event can be antenatal or intra partum

Postpartum patients with acute abdomen—keep
in mind diff: diagnosis of VCP .

Characteristic intra op findings and intra op
involvement of pathologist help to resort to a
more conservative approach and prevent
unnecessary invasive procedures.
