Randomized Controlled Trial Multicenter Study
Results of a prospective, randomized, controlled study of the use of carboxymethylcellulose sodium hyaluronate adhesion barrier in trauma open abdomens.
The open abdominal (OA) approach is a management strategy used in the most severely injured trauma patients. In addition to the morbidity and mortality, a major challenge is the gradual development of dense adhesions that make reoperations progressively more difficult. This randomized, prospective, proof-of-concept study was conducted to determine the effect of carboxymethylcellulose sodium hyaluronate adhesion barrier (CMHAB; Seprafilm, Genzyme Biosurgery, Bridgewater, NJ) on abdominal adhesions and wound characteristics in trauma open abdomens. ⋯ Although CMHAB did not eliminate adhesions in this proof-of-concept study, it limited their severity, particularly in abdomens left open >9 days or requiring ≥5 operations. There was no difference in wound sizes, overall or abdominal complications, or mortality between the groups. Further research is warranted to better delineate potential benefits of CMHAB, especially in the setting of reoperations in post-OA patients.

Resident operative autonomy and case volume is associated with posttraining confidence and practice plans. Accreditation Council for Graduate Medical Education requirements for graduating general surgery residents are four liver and three pancreas cases. We sought to evaluate trends in resident experience and autonomy for complex hepatopancreatobiliary (HPB) surgery over time. ⋯ Roughly one-half of GCR have performed fewer than 10 cases in each of the liver, pancreas, or biliary categories at time of completion of residency. Although the mean number of complex liver and pancreatic operations performed by GCR increased slightly, the median number remained low, and the number of TA cases was virtually zero. Most GCR are unlikely to be prepared to perform complex HPB operations.

Observational Study
Multifaceted interventions improve adherence to the surgical checklist.
Adherence to surgical safety checklists remains challenging. Our institution demonstrated acceptable rates of checklist utilization but poor adherence to all checkpoints. We hypothesized that stepwise, multifaceted interventions would improve checklist adherence. ⋯ A strategic, multifaceted approach to perioperative safety significantly improved checklist adherence over 2 years. Checklist content and process need to reflect local interests and operative flow to achieve high adherence rates. Successful checklist implementation requires efforts to change the safety culture, stakeholder buy-in, and sustained efforts over time.

An overproduction of corticosterone during severe sepsis results in increased apoptosis of immune cells, which may result in relative immunosuppression and an impaired ability to fight infections. We have previously demonstrated that administration of tubastatin A, a selective inhibitor of histone deacetylase-6 (HDAC6), improves survival in a lethal model of cecal ligation and puncture (CLP) in mice. The purpose of this study was to characterize the effects of this treatment on sepsis-induced stress responses and immune function. ⋯ Selective inhibition of HDAC6 in this lethal septic model was associated with a significant blunting of the stress responses, with attenuated thymic and bone marrow atrophy, and decreased splenic apoptosis. Our findings identify a novel mechanism behind the survival advantage seen with tubastatin A treatment.

Multicenter Study Clinical Trial
Time to first take-back operation predicts successful primary fascial closure in patients undergoing damage control laparotomy.
Failure to achieve primary fascial closure (PFC) after damage control laparotomy is costly and carries great morbidity. We hypothesized that time from the initial laparotomy to the first take-back operation would be predictive of successful PFC. ⋯ Data from this prospective, multicenter study demonstrate that delays in returning to the operating room after damage control laparotomy are associated with reductions in PFC. These findings suggest that emphasis should be placed on returning to the operating room within 24 hours after the initial laparotomy if possible (and no later than 48 hours).
