Bile duct injuries associated with laparoscopic and open cholecystectomy: an 11-year experience in one institute.

PURPOSE: Bile duct injury (BDI) represents the most serious complication of laparoscopic cholecystectomy (LC). The aim of this retrospective single-institution study was to evaluate the real incidence of BDI during laparoscopic and open cholecystectomy (OC) in a tertiary academic center in Athens, Greece. METHODS: Between January 1991 and December 2001, 3637 patients underwent cholecystectomy in our department; as LC in 2079 patients (LC group) and as OC in 1558 patients (OC group). All the LCs were performed or supervised by five staff surgeons and all the OCs were performed or supervised by another five staff surgeons. RESULTS: There were 13 BDIs associated with LC (0.62%) and 6 associated with OC (0.38%) (P = 0.317). There was one death associated with BDI after LC. Only two (15.4%) of the BDIs associated with LC occurred within the proposed learning curve limit of 50 LCs per individual surgeon. CONCLUSION: Laparoscopic cholecystectomy is safe and is not associated with a higher incidence of BDI than OC. Moreover, we did not find that the learning curve for LC affected BDI occurrence.

Staphylococcus aureus abscess of the spleen in a beta-thalassemia patient.

Splenic abscesses are rare among abdominal abscesses. We present a case of splenic abscess due to Staphylococcus aureus in a beta-thalassemia major patient. Such a complication may not be coincidental, as beta-thalassemia major patients have an increased susceptibility to infection, which is attributable to a number of immune abnormalities.

Clinical significance of soluble c-erbB-2 levels in the serum and urine of patients with gastric cancer.

BACKGROUND: Both tissue c-erbB-2 expression and serum levels the shed protein have been shown to correlate with tumour stage in a range of adenocarcinomas. This study measured serum and urinary c-erbB-2 levels in patients with gastric cancer, assessing their role in cancer-specific survival and the effects of resectional surgery. PATIENTS AND METHODS: Serum and urinary c-erbB-2 concentrations were measured with commercial enzyme-linked immunosorbent assay in 41 healthy controls and in 54 gastric cancer patients. Serum and urinary c-erbB-2 levels in cancer patients were determined before and 7 days following tumour surgery. RESULTS: Preoperative serum and urinary c-erbB-2 levels in gastric cancer patients were significantly higher than those in controls although there were no significant associations between these levels and tumour pathology. Serum c-erbB-2 levels decreased significantly after radical resection of the primary tumour and were an independent prognostic factor for survival, whereas there were no changes in urinary c-erbB-2 levels after surgery or an association with patient survival. CONCLUSION: Gastric cancer patients show higher serum and urinary c-erbB-2 levels compared to healthy controls. Preoperative serum c-erbB-2 concentration decreases significantly after radical resection of the primary tumour and is an independent prognostic factor for patient survival.
