Chlorhexidine with isopropyl alcohol versus iodine povacrylex with isopropyl alcohol and alcohol- versus nonalcohol-based skin preparations: the incidence of and readmissions for surgical site infections after colorectal operations.
Surgical site infections are a major cause of morbidity and mortality after colorectal operations. Preparation of the surgical site with antiseptic solutions is an essential part of wound infection prevention. To date, there is no universal consensus regarding which preparation is most efficacious. ⋯ The use of 2.0% chlorhexidine with 70.0% isopropyl alcohol versus 0.7% iodine povacrylex with 74.0% isopropyl alcohol or alcohol-based versus nonalcohol-based skin preparations does not significantly influence the incidence of surgical site infections or readmission within 30 days for surgical site infection after clean-contaminated colorectal operations.

Colorectal endoscopic submucosal dissection has gained popularity as a minimally invasive technique for the treatment of colorectal neoplasms in many countries, including Japan. However, most previous studies of endoscopic submucosal dissection had relatively small sample sizes and only included patients treated at specialized centers. Associations between hospital volume and complication rates after colorectal endoscopic submucosal dissection are still poorly understood. ⋯ The present study clearly showed a significant association between higher hospital volume and lower occurrence of severe postoperative bleeding.

Intraoperative fluorescence angiography is beneficial in several surgical settings to assess tissue perfusion. It is also used to assess bowel perfusion, but its role in improving outcomes in colorectal surgery has not been studied. ⋯ Intraoperative fluorescence angiography to assess the perfusion of the colon conduit for anastomosis was not associated with colorectal anastomotic leak. Perfusion is but one of multiple factors contributing to anastomotic leaks. Additional studies are necessary to determine whether this technology is beneficial for colorectal surgery.
