One of the trauma surgeons' daily challenges is the balancing act between negative laparotomy and missed abdominal injury. We opted to characterize the indications that prompted a negative trauma exploratory laparotomy and the rate of missed abdominal injuries in an effort to optimize patient selection for laparotomy. At the Los Angeles County + University of Southern California Medical Center, negative laparotomies and missed injuries are consecutively captured and reviewed at the weekly mortality + morbidity (MM) conferences. All written reports of the MM meetings from January 2003 to December 2008 were reviewed to identify all patients who underwent a negative laparotomy or a laparotomy as a result of an initially missed abdominal injury. Over the 6-year study period, a total of 1871 laparotomies were performed, of which 73 (3.9%) were negative. The rate of missed injuries requiring subsequent laparotomy was 1.3 per cent (25 of 1871). The negative laparotomy rate and the rate of missed injuries did not vary significantly during the study period (2.8 to 4.7%, P = 0.875, and 0.7 to 2.9%, P = 0.689). Penetrating mechanisms accounted for the majority of negative laparotomies (58.9%). The primary indication for negative laparotomy was peritonitis (54.8%) followed by hypotension (28.8%) and suspicious computed tomographic scan findings (27.4%). The complication rate after negative laparotomy was 14.5 per cent, and of these, 10.1 per cent were directly related to the procedure. A low but steady rate of negative laparotomies and missed abdominal injuries after trauma remains. Negative laparotomies and missed abdominal injuries when they occur are still associated with significant complication rates and a prolonged length of stay.

OBJECTIVE To evaluate oncological outcome trends over the last three decades in patients after radical cystectomy (RC) and extended pelvic lymph node (LN) dissection. PATIENTS AND METHODS Retrospective analysis of the University of Southern California (USC) RC cohort of patients (1488 patients) operated with intent to cure from 1980 to 2005 for biopsy confirmed muscle-invasive urothelial bladder cancer. To focus on outcomes of unexpected (cN0M0) LN-positive patients, the USC subset was extended with unexpected LN-positive patients from the University of Berne (UB) (combined subgroup 521 patients). Patients were grouped and compared according to decade of surgery (1980-1989/1990-1999/≥2000). Survival probabilities were calculated with Kaplan-Meier plots, log-rank tests compared outcomes according to decade of surgery, followed by multivariable verification. RESULTS The 10-year recurrence-free survival was 78-80% in patients with organ-confined, LN-negative disease, 53-60% in patients with extravesical, yet LN-negative disease and ≈30% in LN-positive patients. Although the number of patients receiving systemic chemotherapy increased, no survival improvement was noted in either the entire USC cohort, or in the combined LN-positive USC-UB cohort. In contrast, patient age at surgery increased progressively, suggesting a relative survival benefit. CONCLUSIONS Radical surgery remains the mainstay of therapy for muscle-invasive bladder cancer. Yet, our study reveals predictable outcomes but no survival improvement in patients undergoing RC over the last three decades. Any future survival improvements are likely to result from more effective systemic treatments and/or earlier detection of the disease.
