The aim of this study is to compare end to end anastomosis with omega suture versus end to anterior rectal wall in colorectal anastomosis as regard post operative anastomotic leakage, bowel function, operative time and intra operative blood loss.
Patients aged >18 years.
Both sexes.
Recto sigmoidal carcinoma.
Upper rectal cancer.
Patients younger than 18 years
Recurrent or non-resectable cancer
Complicated cancer (e.g., obstructed or perforated)
Previous left-sided colorectal surgery or anorectal surgeries
Parallel
End to end with Omega suture
Other interventionAfter the rectum was divided with a linear stapler, the circular stapler was placed allowing the anvil rod to penetrate the rectal stump near the linear stapler line. An omega suture including both ends of the linear stapler line was placed. The linear stapler line was approximated around the anvil rod of the circular stapler in an omega shape fashion as the omega suture was tied. This technique resulted in a complete resection of linear stapler line by the circular stapler.
End to anterior rectal wall
Other interventionA burse string suture was applied over the anvil of the circular stapler at the transection point of the descending colon using prolene 2/0. The circular stapler introduced though the anus and its rod directed toward the anterior rectal wall and colorectal anastomosis was performed.
Anastomotic leakage
Anastomotic leakage will be measured for 5 days after surgery
Operative time
Operative time will be measured from the start of surgery till the end of surgery.
Hospital stay
Hospital stay will be assessed from admission till discharge from hospital
Time of bowel function
Time of bowel function will be assessed
Wound complications
Wound complications will be recorded as bleeding and infection.
