After analyzing our data, we neither support nor reject the recommendation that all Meckel diverticula found incidentally should be removed, although the procedure today has little risk. If a selective approach is taken, we recommend removing all incidental Meckel diverticula that have any of the 4 features most commonly associated with symptomatic Meckel diverticulum.

BACKGROUND:The authors evaluated sarcopenia as a predictor of cancer-specific survival (CSS) and overall survival (OS) among patients with urothelial cancer of the bladder undergoing radical cystectomy (RC). METHODS: The lumbar skeletal muscle index (SMI) of 205 patients treated with RC for urothelial cancer between 2000 and 2007 was measured. Sarcopenia was classified according to international consensus definitions (SMI of < 55 cm 2 /m 2 for men and < 39 cm 2 /m 2 for women). The CSS and OS were estimated using the Kaplan-Meier method and compared with the log-rank test. Variables associated with CSS and all-cause mortality were summarized with hazard ratios (HRs). RESULTS: Of 205 patients, 141 (68.8%) were sarcopenic. Patients with sarcopenia were older, but were otherwise similar to patients without sarcopenia with respect to sex, Charlson comorbidity index, American Society of Anesthesiologists score, Eastern Cooperative Oncology Group performance status, receipt of neoadjuvant chemotherapy, TNM stage of disease, and tumor grade (P >.05 for all). The median follow-up was 6.7 years, during which time 135 patients died, including 91 who died of bladder cancer. Sarcopenic patients had significantly worse 5-year CSS (49% vs 72%; P 5.003) and OS (39% vs 70%; P 5.003) compared with patients without sarcopenia. Moreover, sarcopenia was found to be independently associated with both increased CSS (HR, 2.14; P 5.007) and all-cause mortality (HR, 1.93; P 5.004) on multivariable analysis. CONCLUSIONS: The presence of sarcopenia was found to significantly increase a patient's risk of CSS and all-cause mortality after undergoing RC for bladder cancer.

Conduit urinary diversion is associated with a high overall complication rate but a low reoperation rate. Long-term followup of these patients is necessary to closely monitor for potential complications from the urinary diversion that can occur decades later.

Decreased renal function is noted in most patients during long-term followup after radical cystectomy. Postoperative hydronephrosis, pyelonephritis and ureteroenteric stricture represent potentially modifiable factors associated with a decrease. Choice of urinary diversion was not independently associated with decreased renal function.
