COMPARATIVE RETROSPECTIVE STUDY OF PATIENTS WHO HAVE UNDERGONE END TO END VERSUS SIDE TO SIDE BOWEL ANASTOMOSIS

Abstract

Bowel anastomoses are frequently done procedures in both elective and emergency general surgery. Our purpose was to compare the two widely used methods of anastomoses i.e. End to End anastomoses and Side to Side anastomoses and the complications associated with both the methods. In our study of 21 cases 14 were end to end type of bowel anastomoses out of which none developed complications whereas out of total 7 cases of side to side anastomosis 5 patients developed complications like minor leak from the anastomotic site ,distention and vomiting  ,delayed passage of flatus  and wound infection, which is a significant number (p value = 0.001) Out of 14 end to end anastomosis patients, all passed flatus in less than three days or on the third post-operative day whereas out of total 7 patients of side to side anastomosis 5 patients took more than  3 post-operative days to pass flatus.(p-value=0.001)It is observed that 13 out of 14 patients of end to end anastomosis started oral feeding before post-operative day 6 and tolerated well, while all the 7 patients started oral feeding after post-operative day 6.(Chi square value=17.063, p-value=0.000) It is concluded that the patients who have undergone side to side anastomosis show poor outcomes than patients who have undergone end to end anastomosis, as the patients with end to end anastomosis develop peristalsis earlier than patients with side to side anastomosis.
