Table 1
The variables and definitions of complication and outcome.
Complications/outcome
Definition
PPOI
Resolution of POI is defined as passage of feces with good toleration of solid food for at least 24 hours. PPOI is diagnosed if POI is not resolved after postoperative day 5; recurrent POI occurring after an apparent resolution of POI was also defined as PPOI [17, 19].
Anastomotic leakage
Defect of the bowel wall integrity at the anastomotic site. A pelvic abscess close to the anastomosis is also considered as anastomotic leakage. The diagnosed leakage were Grade B or C according to classification of Rahbari et al. [18].
Surgical site infection (SSI)
Erythema requiring initiation of antibiotic treatment or a wound requiring partial or complete opening for drainage of a purulent collection.
Pneumonia
Presentation of clinical symptoms including cough, fever, and dyspnoea or consolidation on chest radiography requiring antibiotic treatment with or without a positive sputum culture.
Urinary tract infection
Presents of clinical symptoms, for example, fever, polyuria, and stranguria requiring antibiotic treatment.
Fascia defect
Dehiscence of the abdominal wall with or without the need for reoperation.
Reoperation
During hospital stay, within 30 days postoperative, or during readmission within 30 days after initial discharge.
Length of hospital stay
Day of admission till the day a patient is ready for discharge; this means patient tolerate solid food and had passage of feces, and pain is adequately in control with oral analgesics.
Readmission
Admission within 30 days after discharge for more than 24 hours.
Mortality
