study description:
PRIMARY OBJECTIVES: I. To report the experience of SILS procedure in the treatment of colorectal disease.
II. To standardize the SILS technique.
OUTLINE:
Patients undergo single incision laparoscopic surgery with GelPort® attachment.
After completion of study treatment, patients are followed up at 2 weeks, 3 and 6 months, and at 1 year.

primary outcomes:

• Operative time [ Time Frame: Up to 1 year ] [ Designated as safety issue: No ]
  Summarized using descriptive statistics (i.e. means, standard deviations, 95% confidence intervals for continuous variables, and frequencies for discrete data).
  
• Length of skin and fascial incisions [ Time Frame: Up to 1 year ] [ Designated as safety issue: No ]
  Summarized using descriptive statistics (i.e. means, standard deviations, 95% confidence intervals for continuous variables, and frequencies for discrete data).
  
• Estimated blood loss [ Time Frame: Up to 1 year ] [ Designated as safety issue: No ]
  Summarized using descriptive statistics (i.e. means, standard deviations, 95% confidence intervals for continuous variables, and frequencies for discrete data).
• Oncologic sample including size of specimen removed, number of lymph nodes (LN) removed, pathological type and staging, lymph node, vessel or perineural invasion, and status of margins [ Time Frame: Up to 1 year ] [ Designated as safety issue: No ]
  Summarized using descriptive statistics (i.e. means, standard deviations, 95% confidence intervals for continuous variables, and frequencies for discrete data).

secondary outcomes:

• Quality of life measured using the short form (SF)-12 health related quality of life scale (HQRL) scored using quality metric licensed software [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
  
• Quality of life measured using the SF-12 HQRL scored using quality metric licensed software [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
  
• Quality of life measured using the SF-12 HQRL scored using quality metric licensed software [ Time Frame: 3 months ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
• Quality of life measured using the SF-12 HQRL scored using quality metric licensed software [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
  
• Visual analogue pain scale scored on the scale from 0 to 10 where 0 is no pain, and 10 is the maximum pain [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
  
• Visual analogue pain scale scored on the scale from 0 to 10 where 0 is no pain, and 10 is the maximum pain [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
  
• Visual analogue pain scale scored on the scale from 0 to 10 where 0 is no pain, and 10 is the maximum pain [ Time Frame: 3 months ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
  
• Visual analogue pain scale scored on the scale from 0 to 10 where 0 is no pain, and 10 is the maximum pain [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
  
• Visual analogue cosmesis scale scored on the scale from 0 to 10 where 0 is "worst scar", and 10 is the "best scar" [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
  
• Visual analogue cosmesis scale scored on the scale from 0 to 10 where 0 is "worst scar", and 10 is the "best scar" [ Time Frame: 3 months ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.
  
• Visual analogue cosmesis scale scored on the scale from 0 to 10 where 0 is "worst scar", and 10 is the "best scar" [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  Linear mixed model will be applied with repeated measures considering the observations from the same patient are correlated.

inclusion criteria:

exclusion criteria:
