title: Left-sided colon and colorectal anastomoses: Doppler ultrasound as an aid to assess bowel vascularization. A prospective evaluation of 200 consecutive elective cases.
abstract: Two hundred non-randomized left-sided colon and colorectal anastomoses were performed on 199 consecutive patients admitted over a 4-year period (107 men and 92 woman with a median age of 66 years). There were 117 high anastomoses (above the peritoneal reflection), 86 (74%) of which were hand sewn, and 83 low anastomoses, 78 (94%) stapled with an EEA instrument. Adequate blood supply was assessed with a Doppler ultrasound in all but 5 cases. In ten patients bowel edges to be anastomosed were recut because of a negative Doppler ultrasound reading. One hundred and eighty-nine anastomoses were radiologically controlled. In-hospital post-operative mortality was 2.5% and morbidity 20%. There were two (1%) clinical anastomotic leaks and three (1.5%) radiological leaks. Use of Doppler ultrasound is simple and safe to assess vascularization of the intestinal edges. It may have contributed to the low anastomotic complication rate observed in this series.
