Cosmetic outcome of single-port versus multiple-port laparoscopic surgery in gynaecology

Objective: To compare single-port laparoscopic surgery (SPLS) with multiple-port laparoscopic surgery (MPLS) in terms of cosmetic outcome, operating time, and length of hospital stay. Methods: We retrospectively retrieved all SPLS cases performed in the gynaecology department at Queen Elizabeth Hospital during 2017 to 2018. Same number of matched MPLS cases performed within the same period was retrieved randomly for comparison. Patient satisfaction regarding surgical scar was assessed using the modified Patient Scar Assessment Questionnaire. Only the satisfaction rating was used. Score for each item ranges from 1 (least satisfied) to 4 (very satisfied). Results: 12 patients who underwent SPLS were compared with 12 randomly selected matched patients who underwent MPLS. Both SPLS and MPLS groups scored highly for the Patient Scar Assessment Questionnaire. SPLS group generally scored slightly higher than MPLS group and significantly higher in items: the colour of the wound associated with surrounding tissue, the height of the scar, overall appearance, and overall symptoms from the scar. 91.7% of SPLS patients and 58.3% of MPLS patients preferred the respective techniques if given a choice. Conclusion: Both SPLS and MPLS achieved exceptional cosmesis outcomes, but SPLS was superior to MPLS in some items. More patients may prefer SPLS if they are aware of the technology.
