Comparative study on laparoscopic vaginoplasty using pedicled ileal and sigmoid colon segment transfer / 中华妇产科杂志

ABSTRACT

Objective To study the clinical effect of laparoscopic vaginoplasty using pedicled ileal and sigmoid colon segment.Methods From January 2004 to December 2009,105 cases undergoing laparoscope-assisted vaginoplasty using a vascularized pedicled intestinal flap were studied retrospectively.Operation time,blood loss in operating,bowel movement after operation,postoperation hospital duration,side effect,and artificial vagina were compared between two surgical management.Results The vaginoplasty were preformed successfully in all 105 cases.There were 48 patients treated by aparoscopeassisted ileal vaginoplasty and 57 patients treated by laparoscope-assisted sigmoid colon vaginoplasty.The values of the operation time [(141 ±22) minutes versus (159 ± 18) minutes,P =0.000],blood loss in operating [(42 ±6) ml versus (83 ± 14) ml,P =0.000],bowel movement after operation (36 ±9) hours versus (68 ±8)hours(P =0.000),and postoperation hospital duration [(9.8 ±2.0) days versus (11.1 ± 1.3) days,P =0.004] in the sigmoid colon vaginoplasty group were longer or higher than those in ileal vaginoplasty group (P ＜ 0.05).No intraoprative complication occurred.There were four postoperative complications2 cases with intestinal obstruction in sigmoid colon vaginoplasty group,1 case with urethral orifice stenosis and 1 case with vaginal-rectal fistula in ileal vaginoplasty group.At follow-up of 6-62 months,all artificial vaginas had a capacity of over two fingers in wideness and 12-15 cm in length.Vaginal discharges resembled a milky white water or mucus without odour.Fifty-five patients with sexual intercourse reported satisfactory results.Six patients complained vaginal stenosis5 patients in ileal vaginoplasty group and 1 patient in sigmoid colon vaginoplasty group.Conclusions Laparoscope-assisted vaginoplasty using pedicled ileum or sigmoid colon segment are both the effective ways in forming vagina.The latter management takes more time and blood loss while operating,yet the incidence of vaginal opening contracture appeared to be decreasing trend.
