Accidental rupture of gallbladder during laparoscopic cholecystectorny associated with escape of its content to intraabdominal space is a non-infrequent event. Surgeons worry about potential complications this event could trigger. lt has been reported abscess formation, infections, inflammation, fibrosis, adhesions, etc. We present a case of a feverish patient with malaise, leukocytosis and history of laparoscopic cholecystectorny. Preoperative diagnosis was mixed retroperitoneal mass vs. retroperitoneal abscess. During the surgery we confirmed the second suspection. We suggest surgeons should take precautions to remove all the gallstones from peritoneal space. Also, they should be alert about abdominal pain in patients with previous laparoscopic cholecystectorny.

OBJECTIVES: To design two different surgical patient groups with nonsimilar surgical risks one of them in normal range an the other in high risk. MATERIALS AND METHODS: Two groups of patients of a hundred cases each were evaluated. The first group of healthy kidney donors underwent unilateral nephrectomy, were thoroughly studied in accordance to a preestablished protocol. This protocol was analyzed and we established twelve types of surgical risks, having a risk scale that ranges from I to IV. In the second group of patients who underwent high risk major abdominal surgery we established a scoring method that allows us to determine the patient prognosis. RESULTS: The study demostrated differences in the preoperative assessments.In the fisrt group 99,75% of patients presented risk I, in the other group more than 40 % presented risk II to IV. The morbimortality had a significative differenc...

En 5 años operamos 507 hernias inguinocrurales y 36 recidivadas; la hernia inguinal indirecta fue la más frecuente; encontramos 2 grupos de edades con mayor incidencia de hernias entre los 20 a 29 años y entre los 60 a 69 años, la técnica mayormente utilizada fue la de McVay. De las 39 recidivas 12 fueron provenientes de otro hospital; el análisis de los factores de recidiva de los casos operados en el hospital, muestra que las recidivas son precoces en los primeros 2 años y tardías con más de 10 años de evolución. La intervención sobre la pared abdominal posterior a la hernioplastía es un factor de recidiva. Otra causa de recurrencia son las hernias operadas por cirujanos en entrenamiento. De los 507 pacientes operados y controlados recidivaron 11 casos dando una cifra real de 2.2 % de recidiva.
