RESUMEN
BACKGROUND: Anastomotic leakage is a severe complication after low anterior resection for rectal cancer. With a global increase in registration initiatives, adapting uniform definitions and grading systems is highly relevant. OBJECTIVE: This study aimed to provide clinical parameters to categorize anastomotic leakage into subcategories according to the International Study Group of Rectal Cancer. DESIGN: All of the patients who underwent a low anterior resection in the Netherlands with primary anastomosis were included using the population-based Dutch Surgical Colorectal Audit. SETTINGS: Data were derived from the Dutch Surgical Colorectal Audit. MAIN OUTCOME MEASURES: The development of grade B anastomotic leakage (requiring invasive treatment but no surgery) versus grade C anastomotic leakage (requiring reoperation) was measured. RESULTS: Overall, 4287 patients underwent low anterior resection with primary anastomosis. A total of 159 patients (4%) were diagnosed with grade B anastomotic leakage versus 259 (6%) with grade C. Hospital stay and intensive care unit visits were significantly higher in patients with grade C anastomotic leakage compared with patients with grade B leakage. Mortality in patients with grade C leakage was higher compared with grade B leakage, although nonsignificant (5.8% vs 2.5%; p = 0.12). Multivariate analysis showed that patients with diverting stomas (n = 2866) had a decreased risk of developing grade C leakage compared with grade B (OR = 0.17 (95% CI, 0.10-0.29)). Male patients had an increased risk of developing grade C anastomotic leakage, and patients receiving neoadjuvant treatment before surgery had an increased risk of developing grade B anastomotic leakage. LIMITATIONS: Some possibly relevant variables, such as smoking and nutritional status, were not recorded in the database. CONCLUSIONS: Anastomotic leakage after low anterior resection for rectal cancer was a frequent observed complication in this cohort. Differences in clinical outcome suggest that grade B and C leakage should be considered separate entities in future registrations. In patients with a diverting stoma, the chances of experiencing grade C anastomotic leakage were reduced. See Video Abstract at http://links.lww.com/DCR/A315.

The objective of this study was to identify risk factors for knee osteoarthritis (OA) development in a young to middle-aged population with sub-acute knee complaints. This, in order to define high risk patients who may benefit from early preventive or future disease modifying therapies. Knee OA development visible on radiographs and MR in 319 patients (mean age 41.5 years) 10 years after sub-acute knee complaints and subjective knee function (KOOS score) was studied. Associations between OA development and age, gender, activity level, BMI, meniscal or anterior cruciate ligament (ACL) lesions, OA in first-degree relatives and radiographic hand OA were determined using multivariable logistic regression analysis. OA on radiographs and MR in the TFC is associated with increased age (OR: 1.10, 95 % 1.04-1.16 and OR: 1.07, 95 % 1.02-1.13). TFC OA on radiographs only is associated with ACL and/or meniscal lesions (OR: 5.01, 95 % 2.14-11.73), presence of hand OA (OR: 4.69, 95 % 1.35-16.32) and higher Tegner activity scores at baseline before the complaints (OR: 1.20, 95 % 1.01-1.43). The presence of OA in the TFC diagnosed only on MRI is associated with a family history of OA (OR: 2.44, 95 % 1.18-5.06) and a higher BMI (OR: 1.13, 95 % 1.04-1.23). OA in the PFC diagnosed on both radiographs and MR is associated with an increased age (OR: 1.06, 95 % 1.02-1.12 and OR: 1.05, 95 % 1.00-1.09). PFC OA diagnosed on radiographs only is associated with a higher BMI (OR: 1.12, 95 % 1.02-1.22). The presence of OA in the PFC diagnosed on MR only is associated with the presence of hand OA (OR: 3.39, 95 % 1.10-10.50). Compared to normal reference values, the study population had significantly lower KOOS scores in the different subscales. These results show that knee OA development in young to middle aged patients with a history of sub-acute knee complaints is associated with the presence of known risk factors for knee OA. OA is already visible on radiographs and MRI after 10 years. These high risk patients may benefit from adequate OA management early in life.
