RESUMO
Despite the low morbidity and mortality of laparoscopic cholecystectomy, trauma and infection have been reported. Such complications can produce a misleading clinical picture, as in two cases we observed. Case 1. A symptomatic 56-year-old female patient underwent laparoscopic cholecystectomy. During the operation, the gall bladder ruptured and the contents had to be aspirated from the abdominal cavity. The patient complained of hepatalgia 2 weeks after the operation, then was not seen again for more than 1 year when fever and hepatalgia did not respond to symptomatic treatment. An inter-hepato-renal collection (6 cm in diameter) was punctured under echography. Aspirate culture yielded Pseudomonas aeruginosa. Adapted antibiotic therapy was unsuccessful and surgery was required to empty the abscess then remove a fibrous conjunctive tissue formation. Case 2. A 55-year-old female patient with a history of complete remission after mammectomy for breast cancer underwent laparoscopic cholecystectomy in 1991. Two days after the operation, fever (39 degrees C) was accompanied by abdominal defence. Biliary peritonitis due to imperfect suture of the bile duct was repaired followed by peritoneal lavage-drainage. Per-operative blood samples revealed type 6 Pseudomonas aeruginosa. Despite adapted parenteral antibiotics, fever persisted at 39 degrees C and intense jaundice was observed. A second laparoscopy 14 days later showed inflammatory narrowing of the main bile duct which was drained into a small bowel loop. Eight days later computed tomography revealed multiple abscess in the liver. Transparietal cholangiography was performed and showed that the contrast medium entered the abscesses via the biliary canals. The state of sepsis persisted, jaundice worsened and hepatic encephalopathy developed with obnubilation and flapping tremor. After 1 month of general antibiotherapy, no improvement was seen on computed tomography images and needle biopsy of an abscess led to the identification of resistant type 6 P. aeruginosa. Antibiotics were adapted and administered iv with no clinical improvement. Selective catheterism of the hepatic artery via the femoral access was performed to allow intra-hepatic antibiotic delivery. Three weeks later clinical situation remained unchanged when acute respiratory distress highly suggestive of pulmonary embolism led to death. Autopsy was not performed. In both of these rare cases of infectious complications due to P. aeruginosa after laparoscopic cholecystectomy, the source of contamination remained unknown. Nosocomial infection was suspected.
