Peri-operative complications (gastrointestinal perforation, haemorrhage, or cardiopulmonary event) arose in 64 (11%) patients and were equally distributed between groups. The amount of blood loss and numbers of inserted drains were also equally distributed (data not shown). Approximation of subcutaneous tissue and method of skin closure did not di er between both groups (data not shown). Table 2 shows details of the suture techniques.
