Surgical Versus Nonsurgical Treatment of Acute Achilles Tendon Rupture: A Meta-Analysis of Randomized Trials

BACKGROUND Surgical repair is a common method of treatment of acute Achilles rupture in North America because, despite a higher risk of overall complications, it has been believed to offer a reduced risk of rerupture. However, more recent trials, particularly those using functional bracing with early range of motion, have challenged this belief. The aim of this meta-analysis was to compare surgical treatment and conservative treatment with regard to the rerupture rate, the overall rate of other complications, return to work, calf circumference, and functional outcomes, as well as to examine the effects of early range of motion on the rerupture rate. METHODS A literature search, data extraction, and quality assessment were conducted by two independent reviewers. Publication bias was assessed with use of the Egger and Begg tests. Heterogeneity was assessed with use of the I2 test, and fixed or random-effect models were used accordingly. Pooled results were expressed as risk ratios, risk differences, and weighted or standardized mean differences, as appropriate. Meta-regression was employed to identify causes of heterogeneity. Subgroup analysis was performed to assess the effect of early range of motion. RESULTS Ten studies met the inclusion criteria. If functional rehabilitation with early range of motion was employed, rerupture rates were equal for surgical and nonsurgical patients (risk difference = 1.7%, p = 0.45). If such early range of motion was not employed, the absolute risk reduction achieved by surgery was 8.8% (p = 0.001 in favor of surgery). Surgery was associated with an absolute risk increase of 15.8% (p = 0.016 in favor of nonoperative management) for complications other than rerupture. Surgical patients returned to work 19.16 days sooner (p = 0.0014). There was no significant difference between the two treatments with regard to calf circumference (p = 0.357), strength (p = 0.806), or functional outcomes (p = 0.226). CONCLUSIONS The results of the meta-analysis demonstrate that conservative treatment should be considered at centers using functional rehabilitation. This resulted in rerupture rates similar to those for surgical treatment while offering the advantage of a decrease in other complications. Surgical repair should be preferred at centers that do not employ early-range-of-motion protocols as it decreased the rerupture risk in such patients.

ACGME case logs: Surgery resident experience in operative trauma for two decades.

BACKGROUND Surgery resident education is based on experiential training, which is influenced by changes in clinical management strategies, technical and technologic advances, and administrative regulations. Trauma care has been exposed to each of these factors, prompting concerns about resident experience in operative trauma. The current study analyzed the reported volume of operative trauma for the last two decades; to our knowledge, this is the first evaluation of nationwide trends during such an extended time line. METHODS The Accreditation Council for Graduate Medical Education (ACGME) database of operative logs was queried from academic year (AY) 1989–1990 to 2009–2010 to identify shifts in trauma operative experience. Annual case log data for each cohort of graduating surgery residents were combined into approximately 5-year blocks, designated Period I (AY1989–1990 to AY1993–1994), Period II (AY1994–1995 to AY1998–1999), Period III (AY1999–2000 to AY2002–2003), and Period IV (AY2003–2004 to AY2009–2010). The latter two periods were delineated by the year in which duty hour restrictions were implemented. RESULTS Overall general surgery caseload increased from Period I to Period II (p < 0.001), remained stable from Period II to Period III, and decreased from Period III to Period IV (p < 0.001). However, for ACGME-designated trauma cases, there were significant declines from Period I to Period II (75.5 vs. 54.5 cases, p < 0.001) and Period II to Period III (54.5 vs. 39.3 cases, p < 0.001) but no difference between Period III and Period IV (39.3 vs. 39.4 cases). Graduating residents in Period I performed, on average, 31 intra-abdominal trauma operations, including approximately five spleen and four liver operations. Residents in Period IV performed 17 intra-abdominal trauma operations, including three spleen and approximately two liver operations. CONCLUSION Recent general surgery trainees perform fewer trauma operations than previous trainees. The majority of this decline occurred before implementation of work-hour restrictions. Although these changes reflect concurrent changes in management of trauma, surgical educators must meet the challenge of training residents in procedures less frequently performed. LEVEL OF EVIDENCE Epidemiologic study, level III; therapeutic study, level IV.

Pediatric appendicitis in New England: epidemiology and outcomes

BACKGROUND Acute appendicitis is among the most common indications for surgery in children in the Western world. The epidemiology of acute appendicitis in the United States has not been recently analyzed in a population-based cohort study. METHODS Here, we describe the epidemiology of acute appendicitis in the pediatric population in New England from 2000 to 2006. RESULTS Our results show that there is clustering of perforated and nonperforated appendicitis by hospital catchment area (Moran I index 0.01 and 0.03, respectively). The overall incidence of nonperforated appendicitis decreased over our study period by 9.7% (P < .05), the proportion of perforated appendicitis did not change significantly over our study period, and there was a 38% decrease in the proportion of negative appendectomies (P < .05). CONCLUSIONS There were trends toward increased operative volume for pediatric surgeons as well as sharp increases in the use of laparoscopy and early discharge with home health services. Our results demonstrate that the epidemiology, outcomes, and trends in treatment of acute appendicitis continue to change.

The ACGME case log: General surgery resident experience in pediatric surgery

BACKGROUND General surgery (GS) residents in ACGME programs log cases performed during their residency. We reviewed designated pediatric surgery (PS) cases to assess for changes in performed cases over time. METHODS The ACGME case logs for graduating GS residents were reviewed from academic year (AY) 1989-1990 to 2010-2011 for designated pediatric cases. Overall and designated PS cases were analyzed. Data were combined into five blocks: Period I (AY1989-90 to AY1993-94), Period II (AY1994-95 to AY1998-99), Period III (AY1999-00 to AY2002-03), Period IV (AY2003-04 to AY2006-07), and Period V (AY2007-08 to AY2010-11). Periods IV and V were delineated by implementation of duty hour restrictions. Student t-tests compared averages among the time periods with significance at P < .05. RESULTS Overall GS case load remained relatively stable. Of total cases, PS cases accounted for 5.4% in Period I and 3.7% in Period V. Designated pediatric cases declined for each period from an average of 47.7 in Period I to 33.8 in Period V. These changes are due to a decline in hernia repairs, which account for half of cases. All other cases contributed only minimally to the pediatric cases. The only laparoscopic cases in the database were anti-reflux procedures, which increased over time. CONCLUSIONS GS residents perform a diminishing number of designated PS cases. This decline occurred before the onset of work-hour restrictions. These changes have implications on the capabilities of the current graduating workforce. However, the case log does not reflect all cases trainees may be exposed to, so revision of this list is recommended.

Accreditation Council for Graduate Medical Education (ACGME) Surgery Resident Operative Logs: The Last Quarter Century

Study Objective: To describe secular trends in operative experience for surgical trainees across an extended period using the most comprehensive data available, the Accreditation Council for Graduate Medical Education (ACGME) case logs. Background: Some experts have expressed concern that current trainees are inadequately prepared for independent practice. One frequently mentioned factor is whether duty hours’ restrictions (DHR) implemented in 2003 and 2004 contributed by reducing time spent in the operating room. Methods: A dataset was generated from annual ACGME reports. Operative volume for total major cases (TMC), defined categories, and four index laparoscopic procedures was evaluated. Results: TMC dropped after implementation of DHR but rebounded after a transition period (949 vs 946 cases, P = nonsignificance). Abdominal cases increased from 22% of overall cases to 31%. Alimentary cases increased from 21% to 26%. Trauma and vascular surgery substantially decreased. For trauma, this drop took place well before DHR. The decrease in vascular surgery also began before DHR but continued afterward as well: 148 cases/resident in the late 1990s to 107 currently. Conclusions: Although total operative volume rebounded after implementation of DHR, diversity of operative experienced narrowed. The combined increase in alimentary and abdominal cases is nearly 13%, over a half-years worth of operating in 5-year training programs. Bedrock general surgery cases—trauma, vascular, pediatrics, and breast—decreased. Laparoscopic operations have steadily increased. If the competence of current graduates has, in fact, diminished. Our analysis suggests that operative volume is not the problem. Rather, changing disease processes, subspecialization, reductions in resident autonomy, and technical innovation challenge how todays general surgeons are trained.

Global Surgery Fellowship: A model for surgical care and education in resource-poor countries.

BACKGROUND/PURPOSE Surgical diseases have recently been shown to be a major cause of global morbidity and mortality. Effective methods to decrease the burden of surgical disease and provide care in resource-poor settings are unknown. An opportunity to meet this need exists through collaborative efforts to train local surgeons in specialty care, such as pediatric general surgery. METHODS We present a novel model for the provision of surgical care and education in a resource-poor setting via a collaborative Global Surgery Fellowship program. Through Partners in Health in Haiti, this program placed a fully trained pediatric surgeon at an established rural hospital, both to temporarily serve that community and to teach local surgeons pediatric surgical care. RESULTS The Global Surgery Fellow performed the cases presented here during his term, between July 2009 and June 2010. A total of 147 operative procedures were performed on 131 patients over the course of 12 weeks in Haiti. A total of 134 of the 147 total cases performed (91.2%) were educational cases, in which the Fellow operated with and trained one or more of the following: American medical students, American residents, Haitian residents, or Haitian staff surgeons. CONCLUSION The Global Surgery Fellowship model overcomes many of the traditional challenges to providing adequate surgical care in resource-poor countries. Specifically, it meets the challenge of providing a broad educational experience for many levels of local and foreign physicians, while working within an established locally run health care system. We believe that this model is generalizable to many resource-poor hospitals with permanent local staff that are open to collaboration.

Mesothelial cyst presenting as an irreducible inguinal mass

Inguinal hernias are common in the pediatric population. We describe a 10-year-old child who presented with signs and symptoms suggestive of an incarcerated inguinal hernia. Ultrasound examination demonstrated an aperistaltic multicystic inguinal mass of uncertain origin. The mass was resected, and the adjacent hernia was repaired. Histologic examination identified the mass as a mesothelial cyst. Mesothelial cysts are rare groin lesions in children that can masquerade as an incarcerated inguinal hernia in a child.

Noningested intraperitoneal foreign body causing chronic abdominal pain: a role for laparoscopy in the diagnosis

In this article, we present an unusual case of a young boy who presented with abdominal pain and was found to have a sewing needle that had migrated through the abdominal wall into the peritoneal space. After imaging and endoscopy, the needle was extracted laparoscopically without any evidence of intra-abdominal organ injury and with a good long-term outcome for the child. There are no other such reported cases in the literature. This case highlights the subtleties in management of intra-abdominal foreign bodies in children including rare causes such noningested foreign bodies.

Parenteral Nutrition Utilization After Implementation of Multidisciplinary Nutrition Support Team Oversight A Prospective Cohort Study

BACKGROUND Multidisciplinary nutrition teams can help guide the use of parenteral nutrition (PN), thereby reducing infectious risk, morbidity, and associated costs. Starting in 2007 at Harborview Medical Center, weekly multidisciplinary meetings were established to review all patients receiving PN. This study reports on observed changes in utilization from 2005-2010. MATERIALS AND METHODS All patients who received PN from 2005-2010 were followed prospectively. Clinical data and PN utilization data were recorded. Patients were grouped into cohorts based on exposure to weekly multidisciplinary nutrition team meetings (from 2005-2007 and from 2008-2010). Patients were also stratified by location, primary service, and ultimate disposition. RESULTS In total, 794 patients were included. After initiation of multidisciplinary nutrition meetings, the rate of patients who started PN decreased by 27% (relative risk [RR], 0.73; 95% confidence interval [CI], 0.63-0.84). A reduction in the number of patients receiving PN was observed in both the intensive care unit (ICU) and on the acute care floor (RR, 0.64; 95% CI, 0.53-0.77 and RR, 0.80; 95% CI, 0.64-0.99, respectively). The rate of patients with short-duration PN use (PN duration of <5 days) declined by 30% in the ICU (RR, 0.70; 95% CI, 0.51-0.97) and by 27% on acute care floors (RR, 0.73; 95% CI, 0.51-1.03). CONCLUSIONS Weekly multidisciplinary review of patients receiving PN was associated with reductions in the number of patients started on PN, total days that patients received PN, and number of patients who had short-duration (<5 days) PN use.

FT17. Factors Predicting Limb Salvage in Acute Limb Ischemia Treated at a Tertiary Referral Center

Objectives: In treating critical limb ischemia (CLI), bypass grafting to tibial or paramalleolar arteries plays pivotal role. Though the graft flow (GF) differs significantly among patients, the factors associated with GF are not well studied. Herein, we assessed the factors and developed the predictive equation of GF in tibial or paramalleolar bypass grafting. Methods: CLI patients treated in our institution from January 2012 to November 2016, with bypass to tibial or paramalleolar arteries, were enrolled. In the 137 bypass grafts, 43 grafts were excluded in which postoperative ultrasound imaging within 1 month detected flow-limiting abnormalities. A total of 94 normal grafts were finally enrolled and randomly allotted to two groups: development data set for GF equation (74 grafts) and equation validation data set (20 grafts). Multivariate analysis with stepwise selection was performed to assess and detect factors associated with GF and to obtain GF predictive equation. Analyzed variables were sex, age, runoff, hemodialysis (HD), diabetes mellitus (DM), graft quality (GQ), hypertension, dyslipidemia, smoking history, inflow site, body mass index, cerebrovascular disease, ischemic cardiac disease, and foot infection. Runoff was evaluated with intraoperative angiography, and graded according to Rutherford runoff scoring system; then, the runoff score was classified into three groups: good, fair, or poor. The estimated equation was validated by Bland-Altman method and Student t-test. Actual GF was measured intraoperatively with transit time flowmeter.
