This document summarizes various complications related to ascites. It discusses ascitic fluid infections like spontaneous bacterial peritonitis. It also covers other complications such as hepatic hydrothorax, refractory ascites, and hepatorenal syndrome. For each complication, it provides details on pathogenesis, risk factors, diagnosis, and treatment approaches.
6. When to suspect…
Fever
Abdominal pain
Abdominal Tenderness
Rebound tenderness
Altered sensorium
Leucocytosis
7. Why to suspect….
Prevalence of SBP
33% of patients with SBP land up in renal
impairment
Untreated mortality is 90% which is reduced
to 20% with early diagnosis and prompt
treatment.
No survivors have been reported when
the diagnosis of SBP has been made
after Serum Creatinine is more than 4
mg/dl or after shock had developed
Prevalence
Outpatients 1.5 –3.5%
In hospital >10%
9. Diagnosis
Abdominal Paracentesis & Ascitic
fluid analysis
Ascitic fluid culture
Complete Blood count
Renal function tests
Blood culture
GI endoscopy
X ray abdomen erect
10. Ascitic fluid culture
Culture is positive in ~ 80% of cases
Most common pathogens include Gram-
negative bacteria (GNB), usually
Escherichia coli and Gram-positive cocci
Ascitic fluid culture methods:
◦ Conventional - chocolate agar and
thioglycolate broth
◦ Modified - inoculation of 10 ml of ascitic fluid
in a tryptic soy broth blood culture bottle at
the patient's bedside
11. Blood agar plate inoculated with the ascitic fluid
showing a growth of Klebsiella pneumonia
13. Pathogenesis
Bowel Flora
Bacteria in mesentric LN,
abdominal lymphatics
and thoracic duct
Bactremia
Bacteria in Hepatic
Lymph
Bacterascites
SBP CNNA Sterile Non
neutrocytic ascites
Respiratory tract
infection
Complement deficiency
Urinary tract infection
RE system dysfunction
Poor opsonic activity Good opsonic activity
Modr opsonic activity
14. Culture Negative Neutrocytic
Ascites
1. Ascitic fluid culture grows no
bacteria
2. Ascitic fluid PMN count is > or = 250
cells/mm3
3. No antibiotics has been prescribed
4. No other explanation for an elevated
ascitic PMN count
15. Monobacterial Non-neutrocytic
Bacterascites
1. Positive ascitic fluid culture for a
single organism
2. Ascitic fluid PMN count lower than
250 cells/mm3
3. No evidence of an intra abdominal
surgically treatable source of
infection
16. Polymicrobial Bacterascites
1. Multiple organisms are seen on gram
stain or cultured from the ascitic fluid
2. Ascitic fluid PMN count is lower than
250 cells per mm3
Associated with traumatic paracentesis
17. Secondary Bacterial
Peritonitis
1. Ascitic fluid culture is positive for
multiple organisms
2. Ascitic fluid PMN count more than
250 cells per mm3
3. Intrabdominal surgically treatable
primary source of infection
18. Spontaneous Bacterial Peritonitis
1. Positive ascitic fluid culture for a
single organism
2. Elevated ascitic fluid PMN count of
more than 250 cells/mm3
3. No evidence of surgically treatable
source of infection
19. Risk Factors for SBP
Cirrhosis
◦ Low ascitic fluid proteins
◦ Phagocytic dysfunction
GI bleed
◦ 40 % cumulative probablity of infection
◦ Risk peaks 48 hrs after bleed
Systemic infections

22. Indications for Empirical Antibiotic
Therapy of Suspected
Spontaneous Ascitic Fluid
Infection
•Ascitic fluid neutrophil count ≥
250/mm3 or positive “dipstick” test
•Convincing symptoms or signs of
infection
Inj. Cefotaxim 2 gm i/v q8h
23. Diagnosis Treatment
Monobacterial
Nonneutrocytic
bacterascites
Five days of intravenous antibiotic to
which the organism is highly susceptible
Culture negative
neutrocytic ascites
Five days of intravenous third
generation cephalosporin
Secondary bacterial
Peritonitis
Surgical intervention plus approx 2
weeks of intravenous cephalosporin
plus anti anaerobic drug (metronidazole)
Polymicrobial
Bacterascites
intravenous third generation
cephalosporin plus anti anaerobic drug
(metronidazole)
Spontaneous
Bacterial Peritonitis
Five days of intravenous antibiotic to
which the organism is highly susceptible
24. If preliminary cultures are negative,
paracentesis can be repeated after 48
hrs of therapy to assess the response of
PMN count to antibiotics
Patients with cirrhosis and ascites with
convincing features of infections should
be put on antibiotics even if ascitic fluid
PMN count is less than 250 cells/mm3
25. Treatment contd…
Injectable amoxicillin clavulanic
acid, oral ofloxacin, ciprofloxacin
may be used instead of cephalosporin
Intravenous albumin – 1.5 gm/kg on
the day of diagnosis, with a second
dose of 1.0 gm/kg on the day three.
26. Prognosis
SBP is an indication of End Stage
Liver Disease
33% of patients with SBP land up in
renal impairment
No survivors have been reported
when the diagnosis of SBP has been
made after Serum Creatinine is more
than 4 mg/dl or after shock had
developed
27. Prevention
Indications for preventive measures
◦ Ascitic fluid protein < 1.0 g/dl
◦ Variceal hemorhage
◦ Previous episode of SBP
28. Prior SBP
Cirrhosis with gastrointestinal
hemorrhage

until death or liver transplantation
66% Reduction in recurrence
Intervention
•Norfloxacin 400 mg orally twice daily x 7 days
•Ceftriaxone 1 g intravenously/day x 7 days
Outcome
•73% Reduction in infection
•67% Reduction in infection compared with
norfloxacin
29. Cirrhosis with ascitic fluid
◦ Total protein <1.5 g/dL and either
◦ Child-Turcotte-Pugh score ≥9 and total bilirubin
≥3 mg/dL, or
◦ Creatinine ≥1.2 mg/dL, or
◦ Blood urea nitrogen ≥25 mg/dL, or serum sodium
≤130 mEq/L

Outcome
•31% Reduction in infection
•30% Improvement in survival
31. Hepatic Hydrothorax
Hepatic hydrothorax develops in
approximately 5%–10% of patients with
cirrhosis,
Mechanism
◦ Hypoalbuminemia
◦ Azygous vein hypertension
◦ Leakage of ascitic fluid through
diaphragmatic defect
◦ Trans diaphragmatic migration of fluid via
lymphatics
Pleural effusion is right-sided in 85%,
left-sided in 13%, and bilateral in 2% of
32.
33. Refractory Ascites
Refractory ascites is defined as fluid
overload that is
I. Unresponsive to sodium-restricted diet
and high-dose diuretic treatment (400
mg/day spironolactone and 160 mg/day
furosemide) or
II. Recurs rapidly after therapeutic
paracentesis
34. Diuretic-resistant ascites
ascites that cannot be mobilized or the early
recurrence of which cannot be prevented
because of lack of response to dietary
sodium restriction and maximal doses of
diuretics
Diuretic-intractable ascites
ascites that cannot be mobilized or the early
recurrence of which cannot be prevented
because of the development of diuretic-
induced complications that preclude the use
of effective diuretic dosages.
35. Treatment duration
Patients must be on intensive diuretic therapy
(spironolactone 400 mg/d and
furosemide160mg/d) for at least 1 wk and on a
saltrestricted diet of less than 90 mmol/d
Lack of response
Mean weight loss of < 0.8 kg over 4 days and
urinary sodium output less than the sodium intake.
Early Ascites Recurrence
◦ There is an reappearance of grade 2 or 3 ascites
(clinically detectable) within 4 wk of initial
mobilization.
36. Management
a) Serial large volume therapeutic
paracentesis,
b) Liver transplantation,
c) Transjugular intrahepatic
portasystemic stent-shunt (TIPSS)
d) Peritoneovenous shunt
e) Experimental medical therapy
37. Hepatorenal Syndrome
Potentially reversible functional renal
failure in the setting of liver
dysfunction (cirrhosis with ascites,
acute liver failure and severe alcoholic
hepatitis), in the absence of intrinsic
renal disease.
