Abstract
Elevated cellular proliferation in the vicinity of an anastomosis may explain the enhanced susceptibility to carcinogens. The aim of this study was to determine whether anastomotic cellular proliferation was altered by different suture materials and whether a rise in cell turnover also occurred after a "sutureless" closure. A transverse descending colon enterotomy was repaired with interrupted sutures of 5/0 silk (n = 20), stainless steel (n = 20), or Vicryl (Ethicon, Inc., Somerville, NJ) (n = 20) or by a sutureless technique (n = 20). Using a stathmokinetic technique, crypt cell production rates (CCPR) were calculated at the anastomosis and in the adjacent colon at varying intervals between one week and six months after treatment. Overall colonic cellular proliferation appeared to be elevated at a sutured colotomy for at least three months (P < 0.05). In contrast, no significant elevation in cellular proliferation was observed at sutureless anastomoses. The duration of elevated proliferative response varied among the sutures.
