National trends of 3- versus 2-stage restorative proctocolectomy for chronic ulcerative colitis.

BACKGROUND: Patients undergoing surgical treatment of chronic ulcerative colitis usually undergo a staged approach to IPAA. OBJECTIVE: The purpose of this work was to identify the national trends in approach to IPAA for chronic ulcerative colitis and to evaluate 30-day outcomes using the American College of Surgeons National Surgical Quality Improvement Program. DESIGN: This was a retrospective review study SETTINGS: This study was conducted at a tertiary care cancer center. PATIENTS: Patients with chronic ulcerative colitis who underwent IPAA from 2005 to 2011 were identified. Those who underwent colectomy with pouch procedure were placed in a 2-stage cohort, and those without simultaneous colectomy were part of a 3-stage cohort. Emergent operations were excluded. MAIN OUTCOME MEASURES: Trends in procedure mix, preoperative characteristics, and postoperative 30-day outcomes were compared. Multivariate analysis was used to identify independent risk factors for postoperative infection. RESULTS: Of 2002 patients who underwent IPAA, 1452 (72.5%) underwent 2-stage and 550 (27.5%) underwent 3-stage surgery. Since 2007, the distribution of 2- versus 3-stage procedures has not changed (p = 0.66). At the time of pouch surgery, patients who had undergone 3-stage surgery were less likely to have preoperative corticosteroid therapy, albumin <3 mg/dL, preoperative sepsis, and weight loss (all p < 0.05). Superficial surgical site infection was more common after 3-stage surgery (11.5% vs 7.3%; p < 0.01). After controlling for preoperative factors, wound classification was the only independent predictor of deep incisional or organ space infection (p < 0.01; OR, 1.76; 95% CI, 1.23–2.53). LIMITATIONS: This was a retrospective study. CONCLUSIONS: National trends of 2- versus 3-stage IPAA have remained stable over the last 5 years. Patients who underwent a 3-stage approach were healthier at the time of pouch surgery, with decreased corticosteroid use, hypoalbuminemia, and weight loss. Mixed results were seen for infectious complications with either approach. Prospective research is needed to determine the best approach to IPAA for chronic ulcerative colitis.

Benchmarks for splenectomy in pediatric trauma: How are we doing?☆☆☆★★★

BACKGROUND/PURPOSE Following publication of American Pediatric Surgical Association (APSA) hospital benchmarks for the operative management of blunt splenic trauma in specialized centers, it was found that most hospitals exceeded these benchmarks. We sought to determine if benchmarks were being met a decade later and to identify factors associated with splenectomy in injured children. METHODS Rates of splenic procedures were calculated for children≤19 with a blunt splenic injury (ICD-9 865) using the 2010-2011 National Trauma Data Bank. Multivariable analysis was performed to determine independent predictors of splenectomy. RESULTS Of 8597 children, 24.3% received care at pediatric trauma centers (PTC), 34.6% at adult trauma centers (ATC), and the remaining 41.2% at other centers (OTC). The overall operative rate was 9.2% (3.9% if age≤14, 6.7% if ≤17). Operative rates were higher in children treated at ATC and OTC when compared to PTC. On multivariable analysis, age>14, coexisting injuries, severity of splenic injury, and care at ATC or OTC were predictive of undergoing operative treatment. CONCLUSIONS Operative rates for splenic injuries meet APSA benchmarks at PTC yet remain high at other centers. Care at an ATC or OTC is associated with greater odds of operative management after adjustment for age and injury severity.

Long-term outcomes of ileal pouch-anal anastomosis for pediatric chronic ulcerative colitis.

BACKGROUND Ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for patients with chronic ulcerative colitis (CUC). In the pediatric population, short-term outcomes of IPAA are excellent but long-term data limited. The purpose of this study is to report long-term functional and quality of life outcomes of IPAA in pediatric patients. METHODS Functional outcomes and quality of life (QoL) following IPAA in patients ≤ 18 years of age were prospectively assessed by survey over a 30 year period. Preoperative information, chronic pouchitis and pouch loss were retrospectively reviewed. RESULTS Over 30 years, 202 children with CUC underwent IPAA. Questionnaires were returned by 87% and median (range) survey follow-up was 181.5 (7.8-378.5) months. Postoperative day and night-time stool frequency did not increase over time though incontinence increased slightly. Quality of life (QoL) was generally excellent and stable over time. Crohns disease (CD) was diagnosed in 33 (16%) patients during the follow-up period. Chronic pouchitis occurred in 22 patients and pouch failure in 13 patients. Kaplan Meier estimates of pouch survival at 20 years were 61% for patients with CD and 92% for CUC. CONCLUSIONS Ileal pouch-anal anastomosis has long-term durability as a cure for pediatric chronic ulcerative colitis, with most patients reporting stable bowel function and QoL. Chronic pouchitis and pouch failure affect a minority of patients and require further study.

A simple algorithm reduces computed tomography use in the diagnosis of appendicitis in children

BACKGROUND A diagnostic algorithm for appendicitis in children was created to reduce computed tomography (CT) use owing to the risk of cancer from radiation exposure and cost of CT. This study evaluates the impact of the algorithm on CT use and diagnostic accuracy of appendicitis. METHODS Patients ≤18 years who underwent appendectomy for suspected appendicitis after presenting to the emergency department for 2 years before and 3 years after algorithm implementation were identified. Clinical characteristics and outcomes, including use of CT and negative appendectomy rate, were compared between the pre- and post-implementation periods. Multivariable analysis was used to determine the impact of CT on negative appendectomy. RESULTS We identified 331 patients-41% in the pre- and 59% in the post-implementation period. CT utilization decreased from 39% to 18% (P < .001) after implementation. The negative appendectomy rate increased from 9% to 11% (P = .59). Use of CT did not impact the risk of negative appendectomy (P = .64). CONCLUSION Utilization of CT was significantly reduced after implementation of a diagnostic algorithm for appendicitis without impacting diagnostic accuracy. Given the concern for increased risk of cancer after CT, these results support use of an algorithm in children with suspected appendicitis.

A comparison of two quality measurement tools in pediatric surgery—The American College of Surgeons National Surgical Quality Improvement Program-Pediatric versus the Agency for Healthcare Research and Quality Pediatric Quality Indicators

BACKGROUND/PURPOSE Identifying quality in pediatric surgery can be difficult given the low frequency of postoperative complications. We compared postoperative events following pediatric surgical procedures at a single institution identified by ACS-NSQIP Pediatric (ACS NSQIP-P) methodology and AHRQ Pediatric Quality Indicators (AHRQ PDIs), an administrative tool. METHODS AHRQ PDI algorithms were run on inpatient hospital discharge abstracts for 1257 children in the 2010 to 2013 ACS NSQIP-P at our institution. Four events-pulmonary complications, postoperative sepsis, wound dehiscence and bleeding-were matched between ACS NSQIP-P and AHRQ PDI. RESULTS Events were identified by ACS NSQIP-P in 7.9% of children and by AHRQ PDI in 8.0%. The four matched events were identified in 5.5% and 3.7%, respectively. Specificities of AHRQ PDI ranged from 97% to 100% and sensitivities from 0 to 2%. The largest discrepancy was in bleeding, where AHRQ PDI captured 1 of the 54 events identified by ACS NSQIP-P. None of the 41 pulmonary, sepsis, and wound dehiscence events identified by AHRQ PDI were clinically relevant according to ACS NSQIP-P. CONCLUSIONS Adverse events following pediatric surgery are infrequent; thus, additional measures of quality to supplement postoperative adverse events are needed. AHRQ PDIs are inadequate for assessing quality in pediatric surgery.

Intussusception in adults and the role of evolving computed tomography technology

BACKGROUND The purpose of this study was to describe a single institutions experience with adult intussusception and determine how this was influenced by evolving computed tomography (CT) technology. METHODS Adults treated between 1978 and 2013 for intussusception were reviewed. CT utilization and utilization of multislice technology over time were determined. Sensitivity of CT was calculated. RESULTS A total of 318 patients were identified. CT utilization was 72% and it increased over time. The number of channels ranged from 1 to 128. CT sensitivity was greater than 85% for single and multislice scanners. A lead point was identified in 69% of patients and a malignancy in 40%. Surgical exploration was required in 60% of patients and 40% were managed nonoperatively. CONCLUSIONS The diagnosis of intussusception in adults is increasing over time, particularly idiopathic intussusception. This is associated with increased utilization of highly sensitive CT technology, which facilitates the safe nonoperative management in many patients.

Increased anatomic severity in appendicitis is associated with outcomes in a South African population.

BACKGROUND Severity of emergency general surgery (EGS) diseases has not been standardized until recently. The American Association for the Surgery of Trauma (AAST) proposed an anatomic severity grading system for EGS diseases to facilitate communication and quality comparisons between providers and hospitals. Previous work has demonstrated validity of the system for appendicitis in the United States. To demonstrate generalizability, we aim to externally validate this grading system in South African patients with appendicitis. METHODS Patients with acute appendicitis during 2010 to 2016 were identified at multi-institutional sites within South Africa. Baseline demographics and procedure types were recorded, and AAST grades were assigned based on intraoperative findings. Outcomes included duration of stay, mortality, and Clavien-Dindo complications. Summary statistical univariate and nominal logistic regression analyses were performed to compare AAST grade and outcomes. RESULTS A total of 1,415 patients with a median (interquartile range) age of 19 years (14–28 years) were included (55% men). One hundred percent underwent appendectomy: 63.5% completed via midline laparotomy, 36.5% via limited incision (31.8% via McBurney incision and 4.7% via laparoscopy). Overall, 30-day mortality rate was 1.4% with an overall complication rate of 44%. Most common complications included surgical site infection (n = 147, 10.4%), pneumonia (n = 105, 7.4%), and renal failure (n = 64, 4.5%). Distribution of AAST grade is as follows: Grade 0 (10, 0.7%), Grade 1 (247, 17.4%), Grade 2 (280, 19.8%), Grade 3 (158, 11.3%), Grade 4 (179, 12.6%), and Grade 5 (541, 38.2%). Increased median (interquartile range) AAST grades were recorded in patients with complications, 5 (3–5) compared with those without (2 [1–3], p = 0.001). Duration of stay was increased for patients with higher AAST grades: 4 and 5 (10.6 ± 5.9 days) versus I and II (3.6 ± 4.3 days; p = 0.001). Area under the receiver operating characteristic analysis to predict presence of any complication based on AAST grade was 0.90. CONCLUSION The AAST EGS grading system is valid to predict important clinical outcomes in a South African population with an increased degree of severity on presentation. These results support generalizability of the AAST EGS grading system for appendicitis in a developing nation. LEVEL OF EVIDENCE Prognostic, level II.

Urinary tract infection in elderly trauma patients: review of the Trauma Quality Improvement Program identifies the population at risk.

BACKGROUND Elderly trauma patients are at high risk for urinary tract infection (UTI). Despite this, UTI has been deemed a potentially preventable problem and therefore not reimbursable by the Centers for Medicare and Medicaid Services. Early identification of UTI in these patients should lead to prompt treatment, improved outcomes, and cost savings. Risk factors for UTI development in this population must be elucidated to realize these goals. METHODS The Trauma Quality Improvement Program (TQIP) database was used to analyze elderly patients (≥65 years) admitted as a result of injury during 2011. Patients with genitourinary injuries or undergoing dialysis before admission were excluded. Multivariable logistic regression analysis was conducted to identify UTI risk factors. Mean cost of UTI was calculated based on the assumption of

1,007 per UTI. RESULTS In total, 33,257 patients were identified; 1,492 developed UTI (4.5%). Multiple significant risk factors were identified, including age greater than 75 years, female sex, ascites, moderate head injury, impaired sensorium, congestive heart failure, and duration of hospital stay (all p < 0.05). Assuming that UTIs diagnosed on hospital Day 1 were preexisting, the cost of UTI to TQIP hospitals ranged from
