Comparing thermal welding instrument-assisted laparoscopic radical hysterectomy versus conventional radical hysterectomy in the management of FIGO IB1 squamous cell cervical carcinoma.

PURPOSE OF INVESTIGATION
The authors sought to evaluate the feasibility and acceptability of using the thermal welding technique with thermal ligating shear (TWT-TLS)-assisted laparoscopic radical hysterectomy (LRH) and systemic pelvic lymphadenectomy (SPL) in the management of Stage IB1 squamous cell carcinoma of the cervix.


MATERIALS AND METHODS
The authors compared operating time, blood loss, and other intra- and postoperative parameters and outcomes in 53 patients between May 2003 and April 2007.


RESULTS
Twenty-three patients were treated with TWT-TLS-assisted LRH and SPL (TWT-TLS group) and 30 patients with abdominal radical hysterectomy (ARH) and SPL (ARH group). The surgical time of the TWT-TLS group was significantly shorter than that of the ARH group (221.4 vs 264.6 min, p < 0.05). The blood loss of the TWT-TLS group was less than that of the ARH group (195.7 vs 1,214.7 ml, p < 0.001). The immediate postoperative recovery seemed to be rapid in the TWT-TLS group compared with the ARH group (1.4 vs 3.5 days for full diet, p < 0.001; 8.32 vs 12.14 days for hospital stay, p < 0.001). The recurrence rate between the two groups was similar during the median four-year follow-up (8.7% vs 13.3%).


CONCLUSIONS
TWT-TLS is a safe and efficient method for laparoscopic RH and SPL with reduction of morbidity for early-stage cervical cancer. A further study is needed to confirm the above observation.
