Complete Laparoscopic Type C2 Radical Surgery for Cervical Stump Cancer: No-Look and No-Touch Techniques

Due to previous surgical history and subsequent adhesions between pelvic organs, surgery for cervical stump cancer (CSC) is technically more challenging than surgery for cervical cancer with an intact uterus.¹ We aimed to illustrate the related anatomy, surgical steps and techniques of complete laparoscopic type C2 radical surgery (CLRS) for early-stage CSC.

CLRS for six patients with CSC was performed from January 2021 to January 2022. We demonstrated the detailed skills of parametrial management during CLRS for CSC in case 5 by means of a video. A 58-year-old woman diagnosed with International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IIA1 CSC received CLRS through five operative ports (Fig. 1).

The magnetic resonance imaging (MRI) scans and gross appearance of the specimen are shown in Fig. 2. The median age and body mass index (BMI) of the six patients were 53 years and 23.8, respectively. The median blood loss was 275 mL; the median time of operation was 218 min; the median length of hospitalization was 15 days; and the median time to recover urinary function was 12 days. One patient underwent postoperative radiation for pathologically proven adenocarcinoma with deep stromal invasion,² while the other five did not. After a median follow-up of 24 months, no patients experienced complications, recurrence, or death (Table 1).

This study details the skills of CLRS for CSC, especially space development and the 'no-look, no-touch' tumor-free principle. It is helpful for clinicians to perform safe and standardized surgery on patients with early-stage CSC. Fig. 1 Trocar placement of complete laparoscopic type C2 radical surgery for early-stage CSC.
