Trends in the surgical management of diverticulitis.

ABSTRACT: Sigmoid diverticulitis is an increasingly common Western disease associated with a high morbidity and cost of treatment. Improvement in the understanding of the disease process, along with advances in the diagnosis and medical management has led to recent changes in treatment recommendations. The natural history of diverticulitis is more benign than previously thought, and current trends favor more conservative, less invasive management. Despite current recommendations of more restrictive indications for surgery, practice trends indicate an increase in elective operations being performed for the treatment of diverticulitis. Due to diversity in disease presentation, in many cases, optimal surgical treatment of acute diverticulitis remains unclear with regard to patient selection, timing, and technical approach in both elective and urgent settings. As a result, data is limited to mostly retrospective and non-randomized studies. This review addresses the current treatment recommendations for surgical management of diverticulitis, highlighting technical aspects and patterns of care.

Project description:Diverticulitis is a common diagnosis in the emergency department (ED). Outpatient management of diverticulitis is safe in selected patients, yet the rates of admission and surgical procedures following ED visits for diverticulitis are unknown, as are the predictive patient characteristics. Our goal is to describe trends in admission and surgical procedures following ED visits for diverticulitis, and to determine which patient characteristics predict admission.: We performed a cross-sectional descriptive analysis using data on ED visits from 2006-2011 to determine change in admission and surgical patterns over time. The Nationwide Emergency Department Sample database, a nationally representative administrative claims dataset, was used to analyze ED visits for diverticulitis. We included patients with a principal diagnosis of diverticulitis (ICD-9 codes 562.11, 562.13). We analyzed the rate of admission and surgery in all admitted patients and in low-risk patients, defined as age <50 with no comorbidities (Elixhauser). We used hierarchical multivariate logistic regression to identify patient characteristics associated with admission for diverticulitis.Fryom 2006 to 2011 ED visits for diverticulitis increased by 21.3% from 238,248 to 302,612, while the admission rate decreased from 55.7% to 48.5% (-7.2%, 95% CI [-7.78 to -6.62]; p<0.001 for trend). The admission rate among low-risk patients decreased from 35.2% in 2006 to 26.8% in 2011 (-8.4%, 95% CI [-9.6 to -7.2]; p<0.001 for trend). Admission for diverticulitis was independently associated with male gender, comorbid illnesses, higher income and commercial health insurance. The surgical rate decreased from 6.5% in 2006 to 4.7% in 2011 (-1.8%, 95% CI [-2.1 to -1.5]; p<0.001 for trend), and among low-risk patients decreased from 4.0% to 2.2% (-1.8%, 95% CI [-4.5 to -1.7]; p<0.001 for trend).From 2006 to 2011 ED visits for diverticulitis increased, while ED admission rates and surgical rates declined, with comorbidity, sociodemographic factors predicting hospitalization. Future work should focus on determining if these differences reflect increased disease prevalence, increased diagnosis, or changes in management.

Project description:Optimal surgical management of anterior shoulder instability remains controversial. There is a need to assess the most recent trends for primary and revision shoulder stabilization surgery using a national database significantly larger than those previously utilized.Most shoulder stabilization procedures are performed arthroscopically. Examining revision procedures, we hypothesized that open procedures would result in decreased revision stabilizations compared with arthroscopic procedures and that most revision procedures would be open Bankart or bone transfer procedures regardless of the index procedure technique.Descriptive epidemiology study.The MarketScan Database was searched using International Classification of Diseases-Ninth Revision (ICD-9) and Current Procedural Terminology (CPT) codes to identify patients who underwent any shoulder stabilization procedure between 2008 and 2012. Regression analysis was used to evaluate trends between patient groups. The Cochran-Armitage trend test was used to identify differences in trends seen yearly. Odds ratios (ORs) were calculated to compare the likelihood of undergoing a revision stabilization procedure.A total of 66,564 shoulder stabilization procedures were identified from 2008 through 2012: 60,248 arthroscopic stabilization procedures (90.5%) and 6316 open stabilization procedures (9.5%), including 1623 bone block procedures. Arthroscopic stabilization procedures increased in total number and percentage of all procedures in each year of the study. Bone block procedures increased in number each year, although other open procedures decreased during the study period. Males underwent more stabilization procedures, while patients between the ages of 10 and 19 years were most likely to undergo any procedure. Patients who underwent bone block stabilization were significantly less likely to undergo a second stabilization procedure during the study period when compared with open Bankart repair (OR, 0.582; 95% CI, 0.405-0.836; P < .05) and arthroscopic Bankart repair (OR, 0.587; 95% CI, 0.418-0.824; P < .05). No statistically significant difference in revision stabilization was seen when comparing arthroscopic versus open Bankart repair (OR, 0.934; 95% CI, 0.863-1.139).Although the number of arthroscopic shoulder stabilization surgeries continues to increase, our data show a consistent increase, not seen in prior studies, in the number of bone block procedures. Contrary to some studies, there was no significant difference in the likelihood of a second procedure between patients initially undergoing arthroscopic compared with open Bankart repair.

Project description:ImportanceSurgery after initial lumpectomy to obtain more widely clear margins is common and may lead to mastectomy.ObjectiveTo describe surgeons' approach to surgical margins for invasive breast cancer, and changes in postlumpectomy surgery rates, and final surgical treatment following a 2014 consensus statement endorsing a margin of "no ink on tumor."Design, setting, and participantsThis was a population-based cohort survey study of 7303 eligible women ages 20 to 79 years with stage I and II breast cancer diagnosed in 2013 to 2015 and identified from the Georgia and Los Angeles County, California, Surveillance, Epidemiology, and End Results registries. A total of 5080 (70%) returned a survey. Those with bilateral disease, missing stage or treatment data, and with ductal carcinoma in situ were excluded, leaving 3729 patients in the analytic sample; 98% of these identified their attending surgeon. Between April 2015 and May 2016, 488 surgeons were surveyed regarding lumpectomy margins; 342 (70%) responded completely. Pathology reports of all patients having a second surgery and a 30% sample of those with 1 surgery were reviewed. Time trends were analyzed with multinomial regression models.Main outcomes and measuresRates of final surgical procedure (lumpectomy, unilateral mastectomy, bilateral mastectomy) and rates of additional surgery after initial lumpectomy over time, and surgeon attitudes toward an adequate lumpectomy margin.ResultsThe 67% rate of initial lumpectomy in the 3729 patient analytic sample was unchanged during the study. The rate of final lumpectomy increased by 13% from 2013 to 2015, accompanied by a decrease in unilateral and bilateral mastectomy (P = .002). Surgery after initial lumpectomy declined by 16% (P < .001). Pathology review documented no significant association between date of treatment and positive margins. Of 342 responding surgeons, 69% endorsed a margin of no ink on tumor to avoid reexcision in estrogen receptor-positive progesterone receptor-positive cancer and 63% for estrogen receptor-negative progesterone- receptor-negative cancer. Surgeons treating more than 50 breast cancers annually were significantly more likely to report this margin as adequate (85%; n = 105) compared with those treating 20 cases or fewer (55%; n = 131) (P < .001).Conclusions and relevanceAdditional surgery after initial lumpectomy decreased markedly from 2013 to 2015 concomitant with dissemination of clinical guidelines endorsing a minimal negative margin. These findings suggest that surgeon-led initiatives to address potential overtreatment can reduce the burden of surgical management in patients with cancer.
