title: Use of preoperative visceral echo-color-Doppler in patients candidates to colonic surgery: preliminary report.
abstract: OBJECTIVE
  Postsurgical paralytic ileus is by definition an ileal paralysis longer than three days (72 hours) after a surgery on the gastrointestinal tract. At colorectal surgery we have performed on all candidates a visceral echo-color-Doppler to find a potential correlation with cardiovascular risk factors.
  
  
  METHODS
  We have tested patients undergone to colorectal surgical resection performed by laparoscopic and laparotomic surgery, looking for their atherosclerosis status using ultrasound scan, postsurgical complication, bowel digestive function, anastomotic leak. We have also analyzed for each case the value of glycemia, azotemia, creatinemia, cholesterolemia, triglyceridemia, leukocytemia, mean cell volume, hemoglobinemia, albuminemia and moreover age, disease, pathology localization, kind of surgery, weight and height, body mass index (BMI), ASA status (American Society of Anesthesiologists, electrocardiographic distortions, nicotine dependency, diabetes mellitus type I and II).
  
  
  RESULTS
  The study enrolled 23 patients, 10 male and 13 female. Middle age was 68.65 ± 11.85 years (range 39-90). In the female subgroup mean age was 69.48 years (range 39-90), while in the male subgroup it was 68 years (range 54-81). In 17 cases out of 23 (73.9%) there was a delay in digestive function, of over 72 hours, with a mean time duration of the paralytic ileus of 4.74 ± 1.60 days (range 3-9). Furthermore a statistically significant correlation between albuminemia and hemoglobinemia presurgery values and lower sierical albuminemia presurgery values in patients who were canalized too late (P=0.03; P=0.041) was found. The non-parametrical values analysis sec. Kruskal-Wallis emphasized a significant correlation between the canalization day, the elettrocardiographic evidence of the pathological situation (P=0.023) and the patient's smoking history (0.023). Another significant value was the creatininemia value: lower values of creatininemia were related to a delayed canalization (P=0.035).
  
  
  CONCLUSIONS
  The statistical analysis does not allow to highlight any correlation between the ultrasound diagnosis of atherosclerosis and the delayed canalization.
