Disadvantages of mechanical spacing and why
Answers
Answer:
The merits of mechanical versus manual anastomosis were evaluated in a prospective study of 48 patients undergoing resection of colonic or rectal cancer. The analyzed factors included the time required for construction of the anastomosis, the length of hospital stay, the cost/benefit ratio and complications. The anastomosis was manually performed with monolayer polyglactin 910 sutures in 24 cases and mechanically with an E.E.A. stapler in 24. The anastomosis time averaged 14 min in the suture group and 14.3 min in the stapling group, and the respective hospitalization times were 16 and 17 days. The mean cost was 48,000 lire in the manual, and 200,000 lire in the mechanical group. Four complications occurred in each group. Apart from the cost, no intergroup difference was statistically significant.
