    Pneumoperitoneum most probably due to perforation after this procedure

    :cool: bravooooo
    that is right ..although i wished to have many answers from other memberes...
    lets discuss the diagnosis a little bit


    pneumoperitoneum


    definition : presence of free air inside peritoneal cavity.

    causes:

    *Disruption of wall of hollow viscus

    *Blunt or penetrating trauma

    *Perforating foreign body

    *iatrogenic perforation
    Laparoscopy / laparotomy
    Absorbed in <7 days depending on initial amount of air introduced and body habitus
    Leaking surgical anastomosis
    Endoscopic perforation
    Diagnostic pneumoperitoneum
    Abdominal needle biopsy or catheter placement
    Mistaken thoracentesis or chest tube placement
    Endoscopic biopsy
    *Diseases of GI tract :
    Perforated gastric or duodenal ulcer
    Ingested foreign-body perforation
    Diverticulitis (though abscess is usually walled-off)
    Necrotizing enterocolitis with perforation
    Inflammatory bowel disease (e.g. toxic megacolon)
    Perforated appendix rarely causes a large amount of free air because appendiceal obstruction leaves only a few cc’s of air in appendix if it perforates
    Obstruction from neoplasm, imperforate anus, Hirschsprung’s disease, meconium ileus


    *Extension from:
    Dissection from pneumomediastinum
    Bronchopleural fistula
    Rupture of urinary bladder
    Penetrating abdominal injury

    *Intraperitoneal
    Gas forming peritonitis
    Rupture of abscess


    what do we find in X ray ?

    *Free air beneath diaphragm (crescent sign)
    *Visualization of both sides of the bowel wall
    "Rigler’s sign"
    Normally, only the inside of the bowel (the lumen) is visible unless free air outlines the outer surface of the wall
    *Visualization of the falciform ligament
    Long vertical line to the right of midline extending from ligamentum teres notch to umbilicus; most common structure outlined
    *"Football sign" = large pneumoperitoneum outlining entire abdominal cavity with “laces” representing falciform ligament
    .



    any addition???.....lets get some interactions before the 2nd case..
