Comparative Study
Does race influence outcomes after primary liver transplantation? A 23-year experience with 2,700 patients.
Data about the influence of race on survival after liver transplantation (LT) are limited and conflicting. This study was undertaken to evaluate longterm outcomes for LT in African-American (AA) recipients compared with recipients of other races and to determine factors responsible for any observed differences. ⋯ This is the first study to demonstrate equivalent longterm results after LT for AA and other races. Modern immunosuppression with tacrolimus substantially lowered rejection rates and improved graft and patient survival after LT.

To date, no study has evaluated the potential impact of supplemental restraint use on resource use at a Level I trauma center. We hypothesized that airbag use would be related to decreased injury severity of motor vehicle collision survivors admitted to a Level I trauma center, leading to a decrease in infectious morbidity and hospital resource use. ⋯ Airbags are associated with reduced in-hospital mortality. Airbags are also associated with decreased injury severity, substantial infectious morbidity, and resource use. Cost savings from reduced resource use associated with supplemental restraints could be tremendous.

Adjunctive direct peritoneal resuscitation (DPR) from hemorrhagic shock (HS) improves intestinal blood flow and abrogates postresuscitation edema. HS causes water shifts as a result of sodium redistribution and changes in transcapillary Starling forces. Conventional resuscitation (CR) with crystalloid aggravates water sequestration. We examined the compartment pattern of organ tissue water after HS and CR, and modulation of tissue edema by adjunctive DPR. ⋯ HS decreases IVV. HS-induced water shifts are organ-specific and prominent in gut, lung, and muscle. CR restores central hemodynamics, does not restore IVV, and alters organ-specific TTW distribution. Adjunctive DPR with IP dialysis fluid normalizes TTW and water compartment distribution and prevents edema. Combined effect of DPR and intravascular fluid replacement appears to prevent global tissue edema and improve outcomes from HS.

After completing general surgery residency, surgeons may seek focused additional education or fellowships. Longterm data describing the characteristics of residents selecting fellowships are lacking. Credible data could inform decisions about surgical education paradigms and workforce planning. ⋯ More general surgery residents are pursuing fellowships. The increase has originated disproportionately from resident and residency demographic subsets and has varied temporally across subgroups. The heterogeneity of change suggests a multifactorial etiology. Future directions in surgical education and workforce planning should reflect these findings.

The reported incidence of choledochal cyst (CC) disease varies greatly based on geography. Most large series on CC originate from East Asia. So our understanding of the presentation and natural history of CC disease in western societies is less well characterized. Recognition and surgical treatment are important because of the significant longterm risks of developing cholangiocarcinoma. We report here the largest single-institution western experience with CC disease. ⋯ Western CC disease has a similar demographic profile as that seen in Asia. CCs are more frequently found in adults and girls/women and are associated with a longterm risk of developing cholangiocarcinoma. Presentation differs between adults and children. After complete cyst excision, no patients developed cholangiocarcinoma.
