TH5 - ACUTE PERITONITIS Flashcards
ACUTE PERITONITIS
INFLAMMATION OF PERITONEAL CAVITY WHEN PERITONEAL FLUID INCREASE IN VOLUME WITH TRANSUDATE RICH IN LEUKOCYTE POLYMORPHS + FIBRIN
2 FORMS OF ACUTE PERITONITIS ACCORDING TO SOURCE OF INFECTION?
- PRIMARY - SPONTANEOUS
> infection de novo (new) within peritoneum - SECONDARY
> inflammatory process of peritoneum due to identifiable primary process
WHEN IS DIAGNOSIS OF PRIMARY PERITONITIS ACCEPTED?
> ONLY WHEN CAREFUL EXPLORATION OF PERITONEAL CAVITY DOESN’T ESTABLISH SOURCE OF INFECTION
> every case of acute peritonitis must be considered as secondary acute suppurative peritonitis - TX by operation
SOURCE OF INFECTION FOR ACUTE SECONDARY SUPPURATIVE PERITONITIS?
> GI perforation -MC source of infection
- perforated ulcer, appendix, diverticulum
> Transmural translocation - no perforation
- pancreatitis, ischemic bowel
> Exogenous contamination
- drains
- open surgery
- penetrating abdominal trauma
- female genital tract infection (pelvic inflammatory disease)
WHICH 2 SYNDROMES DEVELOP AS A RESULT OF MASSIVE ABSORPTION OF INFLAMMATORY MEDIATORS FROM PERITONEAL CAVITY IN CASE OF ACUTE SECONDARY SUPPURATIVE PERITONITIS?
- SYSTEMIC INFLAMMATORY RESPONSE SYNDROME (SIRS)
2. MULTI ORGAN DYSFUNCTION SYNDROME (MODS)
2 TYPES OF ACUTE PERITONITIS ACCORDING TO SPREAD OF INFLAMMATORY PROCESS?
- LOCALISED ACUTE PERITONITIS
2. GENERLISED ACUTE PERITONTIS
3 FLOORS OF PERITONEAL CAVITY?
UPPER - above mesocolon transversum (supra colic)
MIDDLE - btwn mesocolon transversum + linea inominata pelvis
LOWER - below linea inominata pelvis
TOTAL PERITONITIS?
Inflammatory process affecting 3 floors of peritoneal cavity
90-100% of peritoneal surface is affected
DIFFUSED PERITONITIS?
Inflammatory process passes outside 2 neighbouring peritoneal area but doesn’t affect more than 2 peritoneal floors
SUBTYPES OF LOCALISED PERITONITIS?
2 SUBTYPES: LOCALISED PERITONITIS
> LOCAL CONFINED PERITONITIS
- intraperitoneal abscess
> LOCAL NON-CONFINED PERITONITIS
- inflammatory process doesn’t pass outside of 2 neighbouring peritoneal floors
5 SUBTYPES OF INTRAPERITONEAL ABSCESS ACCORDING TO THEIR LOCATION?
- left subphrenic
- right subphrenic
- left sub hepatic
- right sub hepatic
- pelvic abscess
MOST COMMON SITE FOR INTRAPERITONEAL ABSCESS FORMATION?
PELVIS
- vermiform appendix often in pelvic position
- fallopian tube also MC site of infection
- pelvic abscess also occurs to any case of diffuse peritonitis + common after anastomotic leakage following colorectal surgery
ABDOMINAL
SIGNS OF INTRAPERITONEAL ABSCESS?
> LOCALISED GUARDING
REBOUND TENDERNESS
RIGIDITY
PHYSICAL SYMPS OF PELVIC ABSCESS?
> MARKED TENDERNESS
> BULGING OF ANTERIOR RECTAL WALL
FIRST CHOICE OF IMAGING METHOD TO SEE PRESENCE OF LOCALISATION OF INTRAPERITONEAL ABSCESS?
ABDOMINAL ULTRASOUND
