Chordomas of the upper cervical spine are rare and present unique surgical challenge. This study aimed to describe the clinical characteristics and surgical management of patients with chordomas of the upper cervical spine.Twenty-one patients with chordomas of the upper cervical spine who were treated in Peking University Third Hospital from January 1999 to October 2012 were retrospectively analyzed. Survival was calculated by the Kaplan-Meier method and was compared between groups using the log-rank test.The postoperative diagnosis was classical chordoma in 20 cases and chondroid chordoma in one case. The mean operative time was 9.5 hours (range 6-17 hours), and the mean blood loss was 2 812 ml (range 700-4 800 ml). There were two postoperative deaths. Unilateral vertebral artery ligation was performed in six patients, cervical nerve roots were cut in six patients, and the external branch of the superior laryngeal nerve was repaired after being cut in one case. Two patients developed postoperative velopharyngeal incompetence, and loosening of the occipitocervical screws was observed in one patient. The recurrence rate was 66.7% (10/15) after a mean follow-up period of 46.8 months (range 14-150 months). The 5- and 10- year overall survival rates were (39.8±13.1)% and (31.9±12.7)%, respectively. There was a significant difference in survival rate between patients who underwent surgery and those who did not.In spite of the high rates of recurrence and complications after surgical treatment of chordomas of the upper cervical spine, intralesional resection combined with adjuvant radiotherapy remains the optimal treatment to prolong survival.
- [Prevention of preterm birth by shirodkar cerclage - clinical results of a retrospective analysis]. [English Abstract, Journal Article]
- Z Geburtshilfe Neonatol 2014 Aug; 218(4):165-70.
In spite of the continuous progress in prenatal care, 1 out of 10 babies is born too early - tendency rising worldwide. As a consequence of the heterogeneous aetiology of preterm birth, there is still no single and efficient interventional therapy. Cerclage is one option for pregnancies with cervical insufficiency, whereas the clinical benefit is discussed controversially. We analyzed in a retrospective study with 120 patients the effect of a cerclage intervention regarding pregnancy prolongation. Patients with cervical incompetence and Shirodkar cerclage were compared to those undergoing conservative treatment. As expected, gestational age at delivery was significantly lower after emergency cerclage (31 weeks) compared to prophylactic (36 weeks) and therapeutic cerclage (35 weeks). Prolongation differs significantly between the prophylactic (18 weeks), therapeutic (14 weeks) and emergency cerclage (10 weeks) groups. Conservative management achieved 8 weeks prolongation. Of note, particularly emergency cerclage in cases with advanced cervical incompetence resulted in a substantially higher pregnancy prolonga-tion (10 weeks) compared to no intervention (one week). The efficiency of cerclage operations has to be assessed in a differentiated manner based on the clinical situation and indication. The clinical benefit depends strongly on proper patient selection.

Cervical incompetence complicates approximately 1 in 500 pregnancies and is the most common cause of second-trimester spontaneous abortion and preterm labor. No prospective or large retrospective studies have compared regional and general anesthesia for cervical cerclage.Following IRB approval, we performed a retrospective study in the two main medical centers over an 8-year period to assess the association of anesthesia choice with anesthetic and obstetric outcomes. Anesthetic and perioperative details were retrospectively collected from fails of all patients undergoing cervical cerclage from 01/01/2005 until 31/12/2012. Details included demographic data, anesthetic technique, PACU data and perioperative complications.We identified 487 cases of cervical cerclage in 327 women during the study period. The most commonly used anesthetic technique was general anesthesia (GA) (402/487; 82.5 %) compared with regional anesthesia (RA) (85/487; 17.5 %). When GA was performed, facemask was the most commonly used technique (275/402; 68.4 %), followed by intravenous deep sedation (61/402; 15.2 %); LMA (51/402; 12.7 %) and tracheal intubation (13/402; 3.2 %). There were no significant differences in demographic characteristics between women receiving general and regional anesthesia. Average duration of suturing the cervix among the GA group was 9.8 ± 1.6 and 10.6 ± 2.1 min in the RA group (p < 0.001). Average length of stay in the operating room in the GA group was 20.5 ± 3.9 and 23 ± 4.6 min in the RA group (p < 0.001). Patients receiving GA received in the PACU more opioids (6.2 versus 1.2 %; p < 0.05) and more non-opioids analgesics (36.8 versus 9.4 %; p < 0.001). Duration of PACU stay was shorter after GA (49.5 ± 18 min) than after RA (62.4 ± 28 min; p < 0.001). There were no other differences in anesthetic or perioperative outcome between groups. This study was not designed to provide evidence that RA reduces the risk of pulmonary aspiration, airway complications or adverse fetal neurological effects from maternal anesthetic exposure.Both regional and general anesthesia were safely used for the performance of cerclage. Patients after general anesthesia had a shorter recovery time but a higher demand for opioids and non-opioids analgesia.

Preterm delivery is the leading cause for infant mortality and morbidity. Cervical incompetence is a recognised cause for both extreme prematurity and second trimester loss. Use of cervical sutures may reduce these risks. We present an assessment of cervical suture use in a busy regional centre.Women who had an attempted cervical suture insertion were identified from theatre records from 2010-2013. Case notes were reviewed retrospectively and index pregnancy was identified as the first attempt to insert a cervical suture. Cervical sutures were categorised as "elective" when there was no evidence of cervical change, "semi-elective" when cervical sutures were attempted following shortening / funnelling of the cervix was identified on transvaginal ultrasound, "rescue" when cervical dilatation was said to have occurred.26 patients were identified. 25 sutures were attempted in singleton pregnancy and 1 in a DCDA twin pregnancy. 10/25 (40%) of women had a previous history of preterm birth. Elective cervical sutures were used in 11/26 (42.3%) cases, Semi-elective sutures in 7/26(26.9%) cases, Rescue sutures in 8/26 cases (30.8). 19/26 (73.1%) of pregnancies resulted in a live birth, of which 11/11 (100%) Elective sutures, 6/7 (85.7%) of Semi-elective sutures and only 2/8 (25%) Rescue sutures resulted in live birth (p 0.0005).Survival in the "rescue" cervical suture group was significantly poorer in comparison to both "elective" and "semi-elective" groups. This data supports the use of early cervical length screening in high risk cases. Further studies are required to identify optima timing of serial cervical length.

- Successful treatment of cervical incompetence using a modified laparoscopic cervical cerclage technique: a cohort study. [JOURNAL ARTICLE]

We introduce a modified surgical method for laparoscopic cervical cerclage (LCC) and compare the operative data and obstetric outcomes to those obtained by traditional vaginal cerclage (TVC).This is a prospective cohort study in a university-affiliated hospital from August 2008 through February 2013. Nineteen patients treated by LCC were prospectively monitored and the treatment outcomes were compared to a control group consisted of 25 patients that were retrospectively studied and treated with TVC using traditional McDonald suture. Laparoscopic cervical cerclage was performed with Mersilene tape and a modified surgical technique. Perioperative complications and obstetric outcomes were compared between LCC and TVC treatment groups.No perioperative complications occurred during LCC treatment. Of the 19 LCC patients, 15 (78.9%) became pregnant during the study period. The fetal salvage rate was 92.3% (12/13) and no adverse events were encountered. The mean gestational age in LCC group was 36.4 weeks, and it was 17.4 weeks longer than their previous pregnancy age, which was significantly higher than obtained by TVC.This modified technique for laparoscopic cervical cerclage demonstrates good obstetric outcomes with low risk of adverse events, which may provide a reasonable alternative to achieve pregnancy success in patients with cervical incompetence.
- Laparoscopic transabdominal cervical cerclage: Case report of a woman without exocervix at 11 weeks gestation. [Journal Article]

Cervical incompetence is characterized by painless dilatation of the incompetent cervix and results in miscarriages and preterm delivery during second trimester. We report a 25-year-old patient, gravid 2, para 1, at 11 weeks' gestation with the diagnosis of cervical incompetence, in whom transvaginal cerclage was not technically possible and laparoscopic cervical cerclage was performed successfully. There were no operative or immediate postoperative complications. A healthy infant was delivered at 35 weeks by cesarean section. Laparoscopic cervical cerclage during pregnancy can be safe and effective treatment for well-selected patients with cervical incompetence and eliminates the need for open laparotomy.
