Its main objective is to evaluate the clinical outcome (including patient reported outcomes) and health economic assessment (HTA) of a new re-usable system for Single Port Laparoscopic Surgery - ENDOCONE SYSTEM developed by Prof Cuschieri by undertaking a randomised controlled prospective clinical trial (RCT) on specific operations performed (on a random allocation basis) by either the traditional multi-port laparoscopic approach or the Single Port- ENDOCONE system by Karl Storz. To this effect, 300 patients meeting the trial inclusion criteria will be randomised over a three year period to have the operation by either of the two approaches.

Primary Outcome Measures:
  • Conversion rate [ Time Frame: During the intervention ]
    1 = if the intervention is converted to open surgery 0 = if the intervention is completed using standard laparoscopy or single port

  • Morbidity [ Time Frame: 30 days ]
    1 = if the patient has surgical complications 0 = no complications

  • Mortality [ Time Frame: 30 days ]

Secondary Outcome Measures:
  • Postoperative course [ Time Frame: 1 week ]
    pain, measured using 1) visual linear analogue scale and 2) analgesic administration

  • Duration of hospital stay [ Time Frame: 6 days ]
    Date of the operation Date of hospital discharge

  • Return of bowel function [ Time Frame: 12, 24, 48 hours ]
    Passage of flatus and/or bowel motion

Estimated Enrollment: 300
