Diabetic patients without signs of peripheral disease or neuropathy had significantly lower TcPo(2) values compared with age- and sex-matched nondiabetic patients. The influence of the examiner on the variance in TcPo(2) measurements was relatively small. We advocate the use of TcPo(2) measurement in diabetic patients to detect subclinical microvascular impairment as an additional tool to assess peripheral vascular disease.

The VSI and the WRI have equal validity in the correct categorization of ACC and adenomas. Furthermore, both indices show a correlation with survival for metastasizing ACC.

BackgroundMechanical bowel preparation (MBP) has been shown to have no influence on the incidence of anastomotic leakage in overall colorectal surgery. The role of MBP in elective surgery in combination with an inflammatory component such as diverticulitis is yet unclear. This study evaluates the effects of MBP on anastomotic leakage and other septic complications in 190 patients who underwent elective surgery for colonic diverticulitis.MethodsA subgroup analysis was performed in a prior multicenter (13 hospitals) randomized trial comparing clinical outcome of MBP versus no MBP in elective colorectal surgery. Primary endpoint was the occurrence of anastomotic leakage in patients operated on for diverticulitis, and secondary endpoints were septic complications and mortality.ResultsOut of a total of 1,354 patients, 190 underwent elective colorectal surgery (resection with primary anastomosis) for (recurrent or stenotic) diverticulitis. One hundred and three patients underwent MBP prior to surgery and 87 did not. Anastomotic leakage occurred in 7.8 % of patients treated with MBP and in 5.7 % of patients not treated with MBP (p = 0.79). There were no significant differences between the groups in septic complications and mortality.ConclusionMechanical bowel preparation has no influence on the incidence of anastomotic leakage, or other septic complications, and may be safely omitted in case of elective colorectal surgery for diverticulitis.
