Patients
From August 1997 to December 2005, 3152 cancer patients underwent colon or gastric surgery under general anesthesia at our hospital. For the statistical analysis, 1675 patients (colon cancer: 801, gastric cancer: 874) who underwent sigmoidectomy, hemicolectomy, low anterior resection, or transverse colon surgery for colon cancer or local gastrectomy or pyloric gastrectomy for gastric cancer were enrolled. The remaining 1477 patients were excluded because the numbers of patients with other
Results
There were 1747 colon surgeries and 1405 gastric surgeries performed as inpatient procedures. The percentages of colon and gastric procedures performed laparoscopically were 37.5% (655/1747) and 12.0% (169/1405), respectively.
The overall SSI rates were 19.7% (129/655) for laparoscopic colon surgeries, 24.5% (267/1092) for open colon surgeries, 4.7% (8/169) for laparoscopic gastric surgeries, and 12.1% (150/1236) for open gastric surgeries (Table 1). For the statistical analysis, 1675 patients
Discussion
SSI rates with laparoscopic surgery were lower than that of open surgery in colon cases by 40% and in gastric cases by 60%. These results are the most important findings reported in this paper. The multivariate analysis identified the operative procedure (laparoscopic vs open surgery) as a risk factor for SSI, and laparoscopic surgery was associated with a significantly lower risk of SSI.
SSI after colon surgery (laparoscopic, 19.7%; open, 24.5%) was considerably higher in this study compared

2021, American Journal of SurgeryCitation Excerpt :Finally, we identified that BMI>30 kg/m2 was an independent predictor of TT complications. Obesity has previously been identified as a risk factor for post-surgical infectious complications following various operations.25,26 However, to our knowledge, there are no studies currently in the literature which identify BMI as a risk factor for TT complication.

2019, European Journal of Vascular and Endovascular SurgeryCitation Excerpt :Hence, it may be reasonable to extend the application time of CiNPT in order to maximise its potential benefits. While diabetes, renal failure, age, and obesity are known risk factors for wound infections,22,23 these confounding factors could not be accounted for by performing a meta-regression analysis, given the small number of studies. Recently, an international multidisciplinary consensus recommendation by Willy et al.21 recommended CiNPT for patients with one or more risk factors, or in those who has a significant history for developing surgical site complications.
