Quality of Life in Patients Undergoing Colorectal Resection for Deep Infiltrating Endometriosis

Pre-post colorectal-resection-and-anastomosis evaluation (mean difference or percentage variation) of anxiety, depression, positivity and well-being, self control, general health and vitality, through the administration of the PGWBI (Psychological General Well-Being Index) to patients. The PGWBI is a brief self-administered questionnaire which contains 20 items rated on a six-point scale, where a higher score indicates a better quality of life and measures six mood states (anxiety, depressed mood, positive well-being, self-control, general health, vitality). The six mood states are scored as follows: 25 for anxiety, 20 for positive well-being and vitality and 15 for remaining

Pre-post colorectal-resection-and-anastomosis evaluation (mean difference or percentage variation) of the coping ability of daily living, through the administration of the GSE (General Self-Efficacy Scale) to patients.

The GSE consists of 10 items, with a 4-point Likert scale ranging from 1 (I Completely Disagree) to 4 (I Completely Agree), aimed at identifying, as expressed in the introduction, self-efficacy beliefs in view of difficult situations

Pre-post colorectal-resection-and-anastomosis evaluation (mean difference or percentage variation) of the ability to "thrive in the face of adversity", through the administration of the CD-RISC (Connor-Davidson Resilience Scale) to patients.

The CD-RISC contains 25 items, all of which carry a 5-point range of responses, as follows: not true at all (0), rarely true (1), sometimes true (2), often true (3), and true nearly all of the time (4). The scale is rated based on how the subject has felt over the past month. The total score ranges from 0-100, with higher scores reflecting greater resilience

Pre-post colorectal resection-and-anastomosis evaluation of the effects that endometriosis can have on women's lives (work and family life, sexual life, fertility issues), through the administration of the EHP-30(Endometriosis Health Profile questionnaire).The EHP-30 consists of a 30-item core questionnaire, covers five subscales (11 items on pain, 6 on control and powerlessness, 6 on emotions, 4 on social support, 3 on self-image), and a second 23-item modular questionnaire contains six subscales (5 items on work life, 2 on relationship with children, 5 on sexual intercourse, 4 on medical profession, 3 on treatment and 4 on infertility). Response categories are rated on a five-point Likert scale (0-4), and items within each subscale are summed to create a raw-score.Each raw scale is translated into a score ranging from 0(best possible health status) to 100 by dividing the total raw scores in each subscale by the maximum possible raw-score within the subscale and multiplying it by 100

Pre-post colorectal-resection-and-anastomosis evaluation (mean difference or percentage variation) of the menstrual pain, through the administration of the VAS (Visual Analogic Scale) to patients. The VAS using a 10-cm line represented the continuum of the patient's opinion of the degree of pain. One extremity of the line represented "unbearable pain," and the other extremity represented "no pain at all." The participants were asked to rate the degree of pain by making a mark on the line. The scores received from the scale were classified into mild dysmenorrhea if it was between 1 and 3 points moderate between 4 and 7 points, and severe between 8 and 10 points

Perioperative and post-operative complications were collected using the Extended Clavien-Dindo classification of surgical complications divided in early (within 30 days after surgery onset) and late (over 30 days after surgery onset). Major complications were defined as those requiring surgical, endoscopic, or radiological intervention (grade III or higher according to the Clavien-Dindo classification), and include rectovaginal fistulae, bowel leakage, pelvic abscesses, and postoperative bleeding after surgery. Minor complications were defined as those that could be solved with a conservative approach (Clavien-Dindo grade I and II)
