Background Retained rectal foreign bodies are a common but incompletely studied problem. This study defined the epidemiology, injury severity, and outcomes after rectal injuries following foreign body insertion. Methods Twenty-two level I trauma centers retrospectively identified all patients sustaining a rectal injury in this AAST multi-institutional trial (2005-2014). Only patients injured by foreign body insertion were included in this secondary analysis. Exclusion criteria were death before rectal injury management or ≤48 h of admission. Demographics, clinical data, and outcomes were collected. Study groups were defined as partial thickness (AAST grade I) versus full thickness (AAST grades II-V) injuries. Subgroup analysis was performed by management strategy (nonoperative versus operative). Results After exclusions, 33 patients were identified. Mean age was 41 y (range 18-57), and 85% (n = 28) were male. Eleven (33%) had full thickness injuries and 22 (67%) had partial thickness injuries, of which 14 (64%) were managed nonoperatively and 8 (36%) operatively (proximal diversion alone [n = 3, 14%]; direct repair with proximal diversion [n = 2, 9%]; laparotomy without rectal intervention [n = 2, 9%]; and direct repair alone [n = 1, 5%]). Subgroup analysis of outcomes after partial thickness injury demonstrated significantly shorter hospital length of stay (2 ± 1; 2 [1-5] versus 5 ± 2; 4 [2-8] d, P = 0.0001) after nonoperative versus operative management. Conclusions Although partial thickness rectal injuries do not require intervention, difficulty excluding full thickness injuries led some surgeons in this series to manage partial thickness injuries operatively. This was associated with significantly longer hospital length of stay. Therefore, we recommend nonoperative management after a retained rectal foreign body unless full thickness injury is conclusively identified.

Purpose Percutaneous endovascular aortic repairs (pEVAR) are associated with access site complications. Two device technique using two Perclose devices has been well established. Combined Perclose and Angioseal technique has been described as well. We sought to determine whether a hybrid Perclose and Angioseal closure technique would safely and effectively establish hemostasis in large bore arteriotomies up to 20-Fr. Methods Patients were identified as candidates for percutaneous access based on pre-operative CT findings, peri-operative ultrasound of femoral vessels, or a combination of the two modalities. Prior to sheath insertion, one Perclose device was predeployed. At the end of pEVAR, device sheath and introducer were withdrawn over a 0.035″ wire, and partially deployed Perclose was fully deployed. The sheath and introducer were fully withdrawn and the arteriotomy was closed with a 6-Fr Angioseal VCD and completion deployment of the Perclose. Patients were followed at day 1 and day 30 and at least 1 year post-intervention. Results A composite endpoint of complications defined as an access site-related bleed or hematoma that required blood transfusion or an extended hospital stay, pseudoaneurysm, arteriovenous fistula, dissection, or retroperitoneal hematoma. The combined technique was initially successful in 44/45 arteriotomies (97.8%) in 24/25 patients (96.0%) with no conversions to cut down. Sheath sizes ranged from 10-Fr to 20-Fr outer diameter (OD), with an average of 15.89-Fr OD. The single device failure was caused by a failure of the footplate to catch during deployment in the Angioseal with a 20-FR arteriotomy. Consequently, that was the only patient in which this closure was attempted for an arteriotomy larger than 19-FR. There were no early or late complications in this series. Conclusions Large bore arteriotomies may be safely and effectively closed using a hybrid percutaneous closure technique for sheaths up to 19-Fr OD. Evaluation of this technique in closure of large bore arteriotomies is ongoing and further investigation is needed to assess the value of this closure in 20-Fr OD sheaths and above.

Severely injured trauma patients are at high risk of developing deep venous thrombosis and pulmonary emboli (PE), and may have contraindications to prophylactic or therapeutic anticoagulation. Retrievable inferior vena cava filters (rIVCFs) are used to act as a mechanical obstruction to prevent PE in high risk populations and those with deep venous thrombosis who cannot be anticoagulated. The removal rate of rIVCFs is variable in trauma centers, including our previous published rate of 50% to 89%/year. Indwelling filters carry a risk of significant morbidity and the success of retrieval decreases as the dwell time increases. We hypothesized that once patients could receive appropriate prophylactic or therapeutic anticoagulation, rIVCF could be removed before hospital discharge without impact on occurrence or recurrence of PE.All trauma patients with rIVCF placed and removed between January 2006 and August 2018 were reviewed. We collected data from record review from admission to 6 months postfilter removal, including demographics, filter indication, filter type, dwell time, placement and removal complications, antithrombosis medications, location of venous thromboembolism, complications, and discharge disposition. Exposure of interest was timing of filter removal: before (BEF) or after hospital discharge (AFT). The outcome of interest was whether the patient had a documented PE within 6 months of filter removal.A total of 281 rIVCFs were placed, 218 were eligible for removal, 72.4% (158/218) were retrieved with 63% (100/158) removed before discharge. Mean filter duration was 26 days and 103 days for the before and after groups, respectively. No differences (p0.05) were noted in the distribution of demographic and clinical factors except for filter indication (venous thromboembolism indication, 95% in AFT vs. 74% in BEF, p = 0.0043). Postremoval PE rates were 0% BEF and 1% AFT (Fisher's exact test, p = 1.000).Our results suggest that removal of rIVCFs before discharge once patients are appropriately anticoagulated is a safe strategy to improve retrieval rates.Therapeutic, level V.

Intestinal anastomoses are commonly performed in both elective and emergent operations. Even so, anastomotic leaks are a highly feared complications of colonic surgeries and can occur in up to 26% of surgical anastomoses, with mortality being up to 39% for patients with such a leak. Currently, there remains a paucity of data detailing the cellular mechanisms of anastomotic healing. Devising preventative strategies and treatment modalities for anastomotic leak could be greatly potentiated by a better understanding of appropriate anastomotic healing. A murine model is ideal as previous studies have shown that the murine anastomosis is the most clinically similar to the human case as compared with other animal models. We offer an easily reproducible murine model of colonic anastomosis in mice that will allow for further illustration of anastomotic healing.

To determine whether lack of insurance is a predictor of poor outcomes and increased healthcare expenditure for SCI patients.Retrospective cohort study of trauma patients admitted with an acute, severe (AIS ≥ 3) SCI and admission score of ASIA-A to a Level 1 trauma center (2012-2016). Patient characteristics and outcomes (LOS, complications) were compared between insured and uninsured patients. Multivariable adjustment was performed using linear regression.Of 76 patients who met eligibility, 44 had insurance and 32 were uninsured (NOINSUR). Despite having similar ventilator days (13 vs. 12.1) and ICU LOS (20.1 vs. 16.8), the NOINSUR group had more ventilator-free days (22.3 vs 6.6; p 0.0001), longer Stepdown Unit length of stay (10.2 vs 2.3; p = 0.0036), and a longer hospital length of stay (35.3 vs 18.7; p = 0.0062).Uninsured SCI patients face longer hospital LOS due to their insurance status and lack of funding for timely rehabilitation placement. This utilizes valuable hospital resources and puts them at risk for hospital related complications and further increased healthcare expenditures.

Background We present an interesting case of a 55-year-old male with a large left chest mass after significant cutaneous bleeding. Computed tomography angiogram of the chest revealed arteriovenous malformation with blood supply from sub-branches of the left subclavian artery, left internal mammary artery, and left external carotid artery. Measuring 5.0 × 14.0 × 10.8 cm, the mass extended superior to the clavicle and inferior to the third rib with medial and lateral borders at the level of the clavicular head and coracoid, respectively. Methods Arteriovenous malformations (AVMs) are characterized by abnormal connections between arteries and veins which bypass the capillary system. Often small and asymptomatic, large AVMs can be painful, prone to bleeding and, if large enough, interfere with activities of daily living. While described involving various parts of the body, most notably in the central nervous system, there is a paucity of literature involving chest wall AVMs. Results Using a staged, multidisciplinary approach, treatment began with an endovascular exclusion of the arterial blood supply, which involved a combination of coil embolization and stent exclusion of feeder vessels. Two days postembolization, the patient underwent an en bloc resection of affected portion of his chest wall. Reconstruction was completed with a combination rotational flap and split-thickness skin graft. Following the procedures, the patient had an uncomplicated recovery. Three years following procedure, he has no signs of recurrence of his AV malformation. Conclusion Surgical planning and indications for giant arteriovenous malformations remains a unique and difficult problem. The complex anatomy and extreme rarity of a chest wall AVM requires a multidisciplinary staged approach but can be treated with a multistage, multidisciplinary surgical approach with satisfactory and long-lasting results.
