Abstract

Background Obese patients are generally believed to be at a higher risk for surgery than those who are not obese, although convincing data are lacking.Methods We prospectively investigated a cohort of 6336 patients undergoing general elective surgery at our institution to assess whether obesity affects the outcome of surgery. Exclusion criteria were emergency, vascular, thoracic, and bariatric operations; transplantation procedures; patients under immunosuppression; and operations done under local anaesthesia. Postoperative morbidity was analysed for non-obese and obese patients (body-mass index <30 kg/m(2) vs >or=30 kg/m(2)). Obesity was further stratified into mild obesity (30.0-34.9 kg/m(2)) and severe obesity (>or=35 kg/m(2)). Risk factors were analysed with univariate and multivariate models.Findings The cohort consisted of 6336 patients, of whom 808 (13%) were obese, 569 (9%) were mildly obese, and 239 (4%) had severe obesity. The morbidity rates in patients who were obese compared with those who were not were much the same (122 [15.1%] of 808 vs 901 [16.3%] of 5528; p=0.26), with the exception of an increased incidence of wound infections after open surgery in patients who were obese (17 [4%] of 431 vs 92 [3%] of 3555, p=0.03). Incidence of complications did not differ between patients who were mildly obese (91 [16.0%] of 569), severely obese (36 [15.1%] of 239), and non-obese (901 [16.3%] of 5528; p=0.19). In multivariate regression analyses, obesity was not a risk factor for development of postoperative complications. Of note, the additional medical resource use as estimated by a new classification of complications showed no differences between patients who were and were not obese.Interpretation Obesity alone is not a risk factor for postoperative complications. The regressive attitude towards general surgery in obese patients is no longer justified.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
