This study describes the purse-string
suture technique using a mini-Pfannenstiel incision for the surgical treatment of large ovarian
dermoid cysts. We investigated intra and postoperative outcomes in 24 patients who underwent removal of large ovarian
dermoid cysts through a mini-Pfannenstiel incision using the purse-string
suture technique. The
surgical procedure was performed by two experienced surgeons. The mean diameter of the
cysts was 11.9 cm. The mean operation time was 46 min and the intraoperative
rupture rate was 8.3%. No patient developed chemical
peritonitis. The length of hospitalisation was 36 h. The recurrence rate was 8.3% in the same ovary at 1-year follow-up. In conclusion, ovarian
dermoid cysts measuring >8 cm in diameter can be effectively treated through a mini-Pfannenstiel incision using the purse-string
suture technique.Impact StatementWhat is already known on this subject?
Dermoid cysts are the most common ovarian germ cell tumours occurring in the second and third decades of life, and these tumours are usually treated surgically. There is a lack of consensus among gynaecologists regarding the optimal surgical treatment modalities for ovarian
dermoid cysts; however, laparoscopic
cystectomy is the gold standard for the surgical treatment of
dermoid cysts. Notably, aspiration of dense cystic contents may be difficult during laparoscopic
cystectomy.What do the results of this study add? Our technique enables easy removal of dense cystic materials including hair and bone fragments. The short operation time, low recurrence rate and the minimal incisional
scar serve as advantages of our novel method.What are the implications of these findings for clinical practice and/or further research? This surgical technique can be successfully used in clinical settings with limited facilities for laparoscopic surgery.
