Comparison of the experimental intestinal anastomoses performed by different surgeons.
OBJECTIVE
This study was designed to determine the effects of different surgeons on the experimental anastomosis studied in rats.


METHODS
Sixteen Wistar-albino rats were equally separated into two groups. The rats operated on by the first surgeon were coded Group 1 and operated on by the other surgeon were coded Group 2. Both surgeons were trained on the gastrointestinal surgery. The procedure of the study were standardized and dictated to the surgeons. Bursting pressure and tissue hydroxyproline content were determined as parameters of the anastomotic strength and healing on the seventh day postoperatively.


RESULTS
The bursting pressures were measured with a digital manometer and anastomotic lines were removed to measure tissue hydroxyproline level. While hydroxyproline value in the first group was 105.60 +/- 9.43 microg/mg dry tissue, it was found to be 104.02 +/- 17.26 microg/mg dry tissue in the second group and this difference was not statistically significant (p=0.521). The bursting pressure was determined as 240.71 +/- 11.65 mmHg in the first group, 190.75 +/- 14.09 mmHg in the second group and the difference was statistically significant (p=0.002). The anastomotic resistances to intraluminal pressure were found statistically different whereas tissue hydroxyproline levels were normal between the groups.


CONCLUSIONS
These results make us to consider mechanical differences occur related to the surgeons in the studies performed with the same technical detail.
