Home intravenous versus oral antibiotics following appendectomy for perforated appendicitis in children: a randomized controlled trial.

PURPOSE: To compare the effect of home intravenous (IV) versus oral antibiotic therapy on complication rates and resource utilization following appendectomy for perforated appendicitis. METHODS: This was a randomized controlled trial of patients aged 4-17 with surgically treated perforated appendicitis from January 2011 to November 2013. Perforation was defined intraoperatively and divided into three grades: I-contained perforation, II-localized contamination to right gutter/pelvis, and III-diffuse contamination. Patients were randomized to complete a ten-day course of home antibiotic therapy with either IV ertapenem or oral amoxicillin-clavulanate. Thirty-day postoperative complication rates including abscess, readmission, wound infection, and charges were compared. RESULTS: Eighty-two patients were enrolled. Forty four (54%) were randomized to the IV group and 38 (46%) to the oral group. IV patients were older (12.3 ± 3.6 versus 10.1 ± 3.6, p < 0.05) with higher BMI (20.9 ± 5.8 versus 17.9 ± 3.5, p < 0.05). There were no differences in gender, comorbidities, or perforation grade (I-20.4% vs. 26.3%, II-36.4% vs. 34.2%, III-43.2% vs. 39.5%, all p > 0.05). Comparing IV to oral, there was no difference in length of stay (4.4 ± 1.5 versus 4.4 ± 2.0 days, p > 0.05), postoperative abscess rate (11.6% vs. 8.1%, p > 0.05), or readmission rate (14.0% vs. 16.2%, p > 0.05). Hospital and outpatient charges were higher in the IV group (p < 0.0001). CONCLUSION: Oral antibiotics had equivalent outcomes and incurred fewer charges than IV antibiotics following appendectomy for perforated appendicitis.

Quality of life following component separation versus standard open ventral hernia repair for large hernias.

INTRODUCTION: Component separation (CS) has become a viable alternative to repair large ventral defects when the fascia cannot be reapproximated. However, the impact of transecting the external oblique to facilitate closure of the abdomen on quality of life (QOL) has yet to be investigated. The study goal was to investigate QOL and outcomes after standard open ventral hernia repair (OVHR) versus CS for large ventral hernias. STUDY DESIGN: Prospective data for all CSs were reviewed and compared with matched OVHR controls. All defects were 100 to 1000 cm2 in size and repaired with mesh. Comorbidities, complications, outcomes, and Carolinas Comfort Scale (CCS) scores, were reviewed. RESULTS: Seventy-four CS patients were compared with 154 patients undergoing standard OVHR with similar defect sizes. Age (56.7±13.0 vs. 54.7 ± 12.3 years, P = .26), defect sizes (299 ± 160 vs. 304 ± 210 cm2, P = .87), and BMI (32.7 ± 6.9 vs. 34.2 ± 9.0 kg/m2, P = .26) were similar in both groups, respectively. There were no differences in major postoperative complications (P = .22), mesh infections (P = 1.00), wound infections (P = .07), or hernia recurrence (P = .09), but wound breakdown increased after CS (10% vs. 1%, P < .001) as did seroma interventions (15% vs. 4%, P = .005). Postoperative CCS scores were similar at 1 month (P = .82) and 1 year (P = .14). CONCLUSIONS: In the first comparative study of its kind, it is found that patient undergoing CS with mesh reinforcement had equal short- and long-term QOL outcomes compared with similar patients who underwent standard OVHR. Whereas wound breakdown and seroma formation are higher, the overall complication, mesh infection, and recurrence rates are similar.

Locum Tenens and Pediatric Surgery: A Position Statement and Practice Guidelines From the American Pediatric Surgical Association (APSA).

The American Pediatric Surgical Association (APSA) Practice Committee endorsed by the Board of Governors presents a Position Statement on the role of locum tenens in the practice of pediatric surgery. The Practice Committee also presents a set of guidelines for locum tenens practice. These recommendations highlight safe practice and quality care that protects the patient as well as the pediatric surgeon by offering best practice standards, defining optimal resources and establishing parameters by which hospitals and locum tenens agencies should abide. These guidelines are intended to foster discussion and contract negotiation as well as inform decision making for a) pediatric surgeons considering locum tenens opportunities, b) host organizations (hospitals and practices) seeking the coverage of a pediatric surgeon, and c) locum tenens companies vetting both surgeons and hospitals for appropriateness of such coverage. This Position Statement and foundational set of guidelines align with APSA's Vision (all children receive the highest quality surgical care) and Mission (to provide the best surgical care to our patients and families by supporting an inclusive community through education, discovery and advocacy).

A review of factors that affect mortality following colectomy.

BACKGROUND: The tightening focus on optimizing surgical outcomes has pushed tracking perioperative mortality to the forefront of interest. The goal of this study is to analyze factors affecting mortality after colorectal resection at a single tertiary care center. MATERIALS AND METHODS: Data were collected from a prospective database for all patients undergoing a colorectal resection at our institution over a 12-y period. Data points included patient demographics, comorbidities, operative details, clinical presentation, postoperative complications, and mortality. RESULTS: A total of 1245 patients were evaluated with 41 deaths (3.3%). Our population was 51% male with an average age of 60.1 ± 15.2 y, mean BMI of 27.5 ± 6.4 kg/m(2), average ASA score of 2.6 ± 0.9, and average of 2.2 ± 1.9 comorbidities. Preoperative factors associated with increased mortality included age, high ASA score, emergent surgery, and the presence of bowel perforation or obstruction (P < 0.05). Intra- and postoperative factors including the transfusion of blood products, length of resection, subtotal colectomy, open versus laparoscopic procedures, the need for reoperation, diagnosis and postoperative complications negatively impact survival (P < 0.05). Stepwise logistic regression demonstrated that high ASA score, emergent procedure, subtotal colectomy, age, obstruction, and open resection as the independent predictors of mortality in a stepwise logistic regression model (P < 0.10). CONCLUSION: Preoperative ASA, emergent procedure, age, open procedure, subtotal colectomy, and obstruction were the independent predictors of mortality in our review. Preoperative optimization and counseling of elderly patients with a high ASA score and/or those requiring an emergency operation should be utilized by surgeons in an effort to improve surgical mortality and patient education.

Prospective, comparative study of postoperative quality of life in TEP, TAPP, and modified Lichtenstein repairs.

INTRODUCTION: The purpose of this study was to compare postoperative quality of life (QOL) in patients undergoing laparoscopic totally extraperitoneal (TEP), transabdominal preperitoneal (TAPP), or modified Lichtenstein (ML) hernia repairs. METHODS: The International Hernia Mesh Registry (2007-2010) was interrogated. 2086 patients who underwent 2499 inguinal hernia repairs were identified. A Carolinas Comfort Score was self-reported at 1-, 6-, 12-months and results were compared. Subgroups analysis and logistic regression were used to identify confounders and to control for significant variables. RESULTS: One hundred seventy-two patients met the exclusion criteria. The distribution of unilateral procedures was TEP (n = 217), TAPP (n = 331), and ML (n = 953). Average follow-up was 12 months. Use of >10 tacks, lack of prostate pathology, recurrent hernia repairs, and bilateral hernia repairs were significant predictors of postoperative pain. One month after surgery 8.9%, 16.6%, and 16.5% were symptomatic for TEP (P = 0.038 vs. ML), TAPP and ML, respectively. At 6 months and 1 year no differences were observed. The number of tacks used varied significantly, with 18.1% of TAPP and 2.3% of TEP with >10 tacks (P = 0.005). The incidence of hernia recurrences were equivalent: TEP (0.42%), TAPP (1.34%), and ML (1.27%). The number or type of tacks utilized did not impact recurrence rates. CONCLUSION: Use of >10 tacks doubles the incidence of early postoperative pain while having no effect on rates of recurrence. There was no difference in chronic postoperative pain comparing ML, TEP, and TAPP including when controlled for tack use.

The addition of lysostaphin dramatically improves survival, protects porcine biomesh from infection, and improves graft tensile shear strength.

BACKGROUND: Lysostaphin (LS), a naturally occurring Staphylococcal endopeptidase, has the ability to penetrate biofilm, and has been identified as a potential antimicrobial to prevent mesh infection. The goals of this study were to determine if LS adhered to porcine mesh (PM) can impact host survival, reduce the risk of long-term PM infection, and to analyze lysostaphin bound PM (LS-PM) mesh-fascial interface in an infected field. METHODS: Abdominal onlay PMs measuring 3×3 cm were implanted in select groups of rats (n=75). Group assignments were based on bacterial inoculum and presence of LS on mesh. Explantation occurred at 60 d. Bacterial growth and mesh-fascial interface tensile strength were analyzed. Standard statistical analysis was performed. RESULTS: Only one out of 30 rats with bacterial inoculum not treated with LS survived. All 30 LS treated rats survived and had normal appearing mesh, including 20 rats with a bacterial inoculum (10(6) and 10(8) CFU). Mean tensile strength for controls and LS and no inoculum samples was 3.47±0.86 N versus 5.0±1.0 N (P=0.008). LS groups inoculated with 10(6) and 10(8) CFU exhibited mean tensile strengths of 4.9±1.5 N and 6.7±1.6 N, respectively (P=0.019 and P<0.001 compared with controls). CONCLUSION: Rats inoculated with S. aureus and not treated with LS had a mortality of 97%. By comparison, LS treated animals completely cleared S. aureus when challenged with bacterial concentrations of 1×10(6) and 1×10(8) with maintenance of mesh integrity at 60 d. These findings strongly suggest the clinical use of LS-treated porcine mesh in contaminated fields may translate into more durable hernia repair.

Ileocolic and Jejunal Intussusceptions Requiring Surgical Intervention in a Pediatric Patient with Posttransplant Lymphoproliferative Disorder.

Posttransplant lymphoproliferative disorder (PTLD) is not uncommon in pediatrics. This case report describes a case of intestinal intussusception that occurred secondary to lymphoid hyperplasia in a child with PTLD following a cardiac transplant. This case was unique in its presentation with multiple areas of intussusception and with need for surgical intervention. The diagnosis of intussusception secondary to lead points from PTLD should be strongly considered in pediatric transplant patients presenting with abdominal complaints.

Endovascular graft repair for blunt traumatic disruption of the thoracic aorta: experience at a nonuniversity hospital.

Blunt thoracic aortic injury (BAI) represents the second leading cause of death from blunt trauma. Admission rates for BAI are extremely low because instant fatality occurs in nearly 75 per cent of patients. Management strategies have transitioned from the more invasive immediate thoracotomy to delayed endograft repair with strict hemodynamic management. In this study, we assess outcomes and complications of open versus endograft repair for BAI at a nonuniversity hospital. Retrospective chart review was conducted on 49 patients admitted to a Level I trauma center who incurred BAI from 2004 to 2011. Collected data points included demographics, mortality, complication rates, and intensive care unit and hospital length of stay (LOS). Twenty-one patients underwent open thoracotomy (OPEN), whereas 28 patients were managed with thoracic endovascular aortic repair (TEVAR). The overall 30-day mortality rate was significantly lower comparing TEVAR to OPEN (7.1 vs 50%, P = 0.028); seven deaths occurred in the OPEN group versus two with TEVAR. Overall complications, including mortality, acute respiratory distress syndrome, renal failure, pneumonia, pulmonary embolism, and cardiac arrest, were fewer after TEVAR (32.1 vs 81.0%, P < 0.001) despite similar injury severity. Survivor hospital LOS (26.0 ± 15.3 vs 27.7 ± 18.7 days, P = 0.79), intensive care unit LOS (13.5 ± 10.9 vs 12.7 ± 8.8 days, P = 0.94), and ventilator days (11.4 ± 13.4 vs 16.4 ± 14.5 days, P = 0.25) were similar. Early nonoperative management with TEVAR for BAIs is a feasible and effective management strategy. Improved patient outcomes over traditional open thoracotomy in the presence of similar injury severity can be seen after TEVAR in the nonuniversity hospital setting.

The green operating room: simple changes to reduce cost and our carbon footprint.

Generating over four billion pounds of waste each year, the healthcare system in the United States is the second largest contributor of trash with one-third produced by operating rooms. Our objective is to assess improvement in waste reduction and recycling after implementation of a Green Operating Room Committee (GORC) at our institution. A surgeon and nurse-initiated GORC was formed with members from corporate leadership, nursing, anesthesia, and OR staff. Initiatives for recycling opportunities, reduction of energy and water use as well as solid waste were implemented and the results were recorded. Since formation of GORC in 2008, our OR has diverted 6.5 tons of medical waste. An effort to recycle all single-use devices was implemented with annual solid waste reduction of approximately 12,860 lbs. Disposable OR foam padding was replaced with reusable gel pads at greater than $50,000 per year savings. Over 500 lbs of previously discarded batteries were salvaged from the OR and donated to charity or redistributed in the hospital ($9,000 annual savings). A "Power Down" initiative to turn off all anesthesia and OR lights and equipment not in use resulted in saving $33,000 and 234.3 metric tons of CO2 emissions reduced per year. Converting from soap to alcohol-based waterless scrub demonstrated a potential saving of 2.7 million liters of water annually. Formation of an OR committee dedicated to ecological initiatives can provide a significant opportunity to improve health care's impact on the environment and save money.

Application of subcutaneous talc after axillary dissection in a porcine model safely reduces drain duration and prevents seromas.

BACKGROUND: Talc, the most common pleurodesis agent, has recently been shown to prevent seromas and decrease drain duration when placed subcutaneously after large subcutaneous dissection accompanying open ventral hernia repair. We hypothesized that talc would decrease drain duration and prevent seromas after axillary dissection without local or systemic side effects. STUDY DESIGN: Six pigs underwent full, bilateral axillary dissection (n 12 dissections). Three animals each had aerosolized small particle (SP) talc and large particle (LP) talc sprayed unilaterally (TALC) before closure, with the contralateral axillary dissection serving as the control (NOTALC). Functional status, wound complications, and drain duration were recorded. Local neurovascular structures and systemic organs were harvested at 28 days, processed with hematoxylin and eosin, and examined under normal and polarized light microscopy by blinded physicians. RESULTS: All pigs were back to baseline functional status by 72 hours. Two seromas (33%) were noted in the NOTALC dissections vs 0 in the TALC group (0%). Drain duration was significantly decreased in TALC vs NOTALC dissections (8.3 ± 2.7 vs 12.0 ± 3.2 days, p = 0.03), as was total drain volume (222.5 ± 127.1 mL vs 334.2 ± 137.9 mL, p = 0.02). Gross and histologic evaluation revealed neurovascular structures to be intact. Minimal splenic deposition of talc within macrophages without evidence of injury was identified in all specimens, with fewer deposits in the large particle talc group. Serum laboratory examination at time of harvest revealed all animals to have normal values. CONCLUSIONS: Direct application of talc throughout the wound after axillary dissection in pigs decreased drain duration and drain volume and prevented seroma formation. Gross, histologic, and serum laboratory evaluation demonstrated no talc-related local or systemic complications. Aerosolized talc is an effective and safe pretreatment to prevent seromas and hasten drain removal after axillary dissection.

Full-scale regional exercises: closing the gaps in disaster preparedness.

BACKGROUND: Man-made (9/11) and natural (Hurricane Katrina) disasters have enlightened the medical community regarding the importance of disaster preparedness. In response to Joint Commission requirements, medical centers should have established protocols in place to respond to such events. We examined a full-scale regional exercise (FSRE) to identify gaps in logistics and operations during a simulated mass casualty incident. METHODS: A multiagency, multijurisdictional, multidisciplinary exercise (FSRE) included 16 area hospitals and one American College of Surgeons-verified Level I trauma center (TC). The scenario simulated a train derailment and chemical spill 20 miles from the TC using 281 moulaged volunteers. Third-party contracted evaluators assessed each hospital in five areas: communications, command structure, decontamination, staffing, and patient tracking. Further analysis examined logistic and operational deficiencies. RESULTS: None of the 16 hospitals were compliant in all five areas. Mean hospital compliance was 1.9 (± 0.9 SD) areas. One hospital, unable to participate because of an air conditioner outage, was deemed 0% compliant. The most common deficiency was communications (15 of 16 hospitals [94%]; State Medical Asset Resource Tracking Tool system deficiencies, lack of working knowledge of Voice Interoperability Plan for Emergency Responders radio system) followed by deficient decontamination in 12 (75%). Other deficiencies included inadequate staffing based on predetermined protocols in 10 hospitals (63%), suboptimal command structure in 9 (56%), and patient tracking deficiencies in 5 (31%). An additional 11 operational and 5 logistic failures were identified. The TC showed an appropriate command structure but was deficient in four of five categories, with understaffing and a decontamination leak into the emergency department, which required diversion of 70 patients. CONCLUSION: Communication remains a significant gap in the mass casualty scenario 10 years after 9/11. Our findings demonstrate that tabletop exercises are inadequate to expose operational and logistic gaps in disaster response. FSREs should be routinely performed to adequately prepare for catastrophic events.

Application of subcutaneous talc in hernia repair and wide subcutaneous dissection dramatically reduces seroma formation and postoperative wound complications.

Wound complications after large ventral hernia repairs when combined with wide subcutaneous dissection (OVHR/WSD) are common (33 to 66%). We evaluate a novel technique of applying talc to wound subcutaneous tissues to decrease wound complications. We accessed our prospectively collected surgical outcomes database for OVHR/WSD procedures performed. Patients were divided into those that did and did not receive subcutaneous talc (TALC vs NOTALC). Demographics intraoperative and outcomes data were collected and analyzed. The study included 180 patients (n = 74 TALC, n = 106 NOTALC). Demographics were all similar, but hernias were larger in the TALC group. TALC patients had their drains removed earlier (14.6 vs 25.6 days; P < 0.001) with dramatic reduction in postoperative seromas requiring intervention (20.8 to 2.7%; P < 0.001) and cellulitis (39.0 to 20.6%; P = 0.007). Short-term follow-up demonstrates significantly higher recurrence rates in the NOTALC group with each recurrence related to infection. The use of talc in the subcutaneous space of OVHR/WSD results in significantly earlier removal of subcutaneous drains, fewer wound complications, and a decrease in early hernia recurrence. Use of talc in the subcutaneous space at the time of wound closure is an excellent technique to decrease wound complications in large subcutaneous dissections.
