In recent years an adjusted method of performing an abdominoperineal excision (APE) - so called&#xd;
extralevator APE - has been developed and internationally spread. It has been proposed to decrease&#xd;
intraoperative perforations and non-radical surgery and therefor improve local cancer control and decrease&#xd;
rates of local recurrences as compared to standard APE. This thesis aims to investigate if the oncological&#xd;
outcome of ELAPE is superior to standard APE and to explore the association between patient reported&#xd;
intrusive thoughts and QoL as well as to type of surgery performed three years after surgery and to compare&#xd;
outcome to that found in a normative Swedish cohort.&#xd;
Data on all Swedish patients operated with any kind of APE in the years 2007-2009 were collected from the&#xd;
Swedish ColoRectal Cancer Registry and short-term oncological outcome was measured (i.e. perforations&#xd;
and non-radical surgery) as well as short-term complications and mortality. In order to be able to differ&#xd;
between APE and ELAPE, all patients’ operation notes were collected from the hospital charts where they&#xd;
had been operated, and analysed with regard to which operating technique had been used. When 3-years&#xd;
local recurrence data were available in the registry these data were also collected from the registry and&#xd;
analysed with regard to what operation had been performed. Furthermore, a special questionnaire was&#xd;
developed in order to be able to measure a number of health-related QoL parameters specific for this group&#xd;
of patients. The questionnaire was sent to all patients alive 3 years following surgery and data on QoL was&#xd;
compared to data from a Swedish normative population.&#xd;
Short-term oncological results were the same for both groups with regard to perforation and non-radical&#xd;
surgery. There were fewer intraoperative perforations for a subgroup of the most distal tumours in the&#xd;
ELAPE group but not for the entire group. There were more wound infections for the ELAPE-group.&#xd;
Local recurrences after 3 years were significantly more common in the ELAPE group as compared to&#xd;
standard APE but there was no difference between groups in overall survival. Intraoperative perforation was&#xd;
significantly associated with higher risk of local recurrence.&#xd;
A large proportion of survivors after abdominoperineal excision for rectal cancer have a quality of life&#xd;
comparable to a normative population, however many suffer from a symptom of stress, negative intrusive&#xd;
thoughts, which significantly decrease overall quality of life.&#xd;
Oncological outcome following ELAPE is not superior to standard APE. ELAPE is associated with more&#xd;
perineal wound complications. This method should be used in selected patients with high risk of&#xd;
intraoperative perforation.</dim:field>
