  • VideoAssisted Thoracoscopic Surgery for Posterior Mediastinal Tumors

    Abstract: Objective To discuss the security, effectiveness and risk factors of videoassisted thoracoscopic surgery for posterior mediastinal tumors. Methods We retrospectively analyzed the data of 59 patients including 36 men and 23 women who underwent thoracoscopic resection of posterior mediastinal tumors in People’s Hospital of Peking University from May 2001 to July 2009. Their age ranged from 6 to 73 years old with an average age of 40.6 years old. The average maximum diameter of the tumors was 4.86 cm. All procedures were performed under general anesthesia and tumors were cut out with three ports. The anterior port was extended to 6 to 10 cm when conversion to thoracotomy was needed. After mediastinal pleura were opened, the tumor was stripped out along the outside of peplos and the vascular pedicle nerves were managed respectively. Results All surgeries were carried out successfully. The surgical duration, perioperative blood loss, postoperative chest tube duration and postoperative stay in hospital were respectively 45-300 min(125.80±57.40 min), 10-1 000 ml(168.10±157.70 ml), 1-10 d(2.50±1.74 d), and 2-14 d(5.24±2.24 d). There were 6 cases of conversion to open thoracotomy with a conversion rate of 10.2%. Postoperative pathology showed that there were 46 cases of neurogenic tumors, 10 cases of cyst, 2 cases of teratoma, and 1 case of lipoma. Follow-up was done on 51 cases for a period of 7-108 months(55.0±24.0 months) and 8(13.6%) cases were missed out during the period. No recurrence or death occurred during the followup. Logistic multivariable analysis showed that maximum diameter of the tumor ≥6 cm was the independent risk factor for extending operative time (OR=1.932,P=0.004), increasing perioperative blood loss (OR=2.267,P=0.002), increasing conversion rate to thoracotomy (OR=3.123,P=0.004) and increasing postoperative complication rate (OR=1.778,P=0.013). Conclusion Videoassisted thoracoscopic surgery for posterior mediastinal tumor is safe and effective. Maximum diameter of the tumor ≥6 cm is an independent risk factor for increasing operation difficulty and risk.

  • ANATOMIC FEATURES OF POSTERIOR SEPTUM OF KNEE JOINT AND ITS APPLICATION IN POSTERIOR TRANS-SEPTAL PORTAL FOR ARTHROSCOPIC SURGERY

    Objective To summarize the anatomic features of the posterior septum of the knee joint and its application in posterior trans-septal portal for arthroscopic surgery. Methods The literature related to posterior septum of the knee joint and arthroscopic surgery was extensively reviewed and analyzed. Results The posterior septum of the knee joint has more mechanoreceptors and blood vessels in the upper part, which are close to arteria popliteal at the tibial plateau level; the posterior compartment is divided into wider posteromedial and narrower posterolateral compartments. A safe arthroscopic trans-septal portal is established, in the knee flexion of 90°, in a lateral-to-medial direction, and with an inserting location below the middle of posterior septum. Conclusion The establishment method of posterior trans-septal portal is not uniform and all the features of posterior septum should be considered to decrease the complications.

  • ARTHROSCOPIC RESECTION OF BENIGN TUMOR IN THE KNEE POSTERIOR SEPTUM

    ObjectiveTo explore the technique of arthroscopic resection of benign tumor in the knee posterior septum and to evaluate its clinical results. MethodsBetween June 2008 and June 2012, 12 cases of benign tumor in the knee posterior septum were treated by arthroscopic surgery. There were 8 males and 4 females with an average age of 36.5 years (range, 22-50 years). The average disease duration was 8.4 months (range, 3 months to 2 years). Of 12 cases, there were 2 cases of chronic synovitis, 5 cases of ganglion, 4 cases of tenosynovial giant cell tumor, and 1 case of synovial hemangioma; solitary tumor involved in the knee posterior septum in 10 cases, and in the posterior septum and other part of the knee in 2 cases. All the patients underwent tumor removal under arthroscope with routine anterolateral and anteromedial portal, additional posteromedial portal and/or posterolateral portal. Trans-septal approach was used in 6 cases because the tumors located in the middle of the posterior septum. ResultsAll wounds healed by first intention with no complications such as infection, haematoma in the knee, injury of vessels and nerves, deep vein thrombosis, osteofascial compartment syndrome, or cutaneous necrosis. All patients were followed up 12-46 months with an average of 18.5 months. All patients achieved relief of knee pain and improvement of knee movement. The range of motion of the knee was significantly improved from (57.08±12.52)° at pre-operation to (120.83±13.95)° at last follow-up (t=-12.84, P=0.00). The visual analogue scale (VAS) score was significantly reduced from 5.00±1.04 at pre-operation to 1.50±0.91 at last follow-up (t=-18.00, P=0.00). The Lysholm score was significantly improved from 49.50±9.07 at pre-operation to 84.58±6.82 at last follow-up (t=-8.04, P=0.00). ConclusionThe benign tumor in the knee posterior septum can be completely resected under arthroscope, and the procedure is minimally invasive and useful to the restore knee function.

  • The clinical efficacy of Da Vinci robot versus video-assisted thoracoscopic surgery in the treatment of posterior mediastinal tumors: A retrospective cohort study

    ObjectiveTo compare the short-term clinical effects of Da Vinci robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in the treatment of posterior mediastinal tumors, and to explore the advantages of RATS posterior mediastinal tumor resection. MethodsThe clinical data of patients who underwent posterior mediastinal tumors resection through the lateral chest approach admitted to the same medical group in the Department of Thoracic Surgery of the First Hospital of Lanzhou University between January 2019 to January 2023 were retrospectively analyzed. According to the different surgical methods, the patients were divided into a RATS group and a VATS group. The clinical data were compared between the two groups. ResultsA total of 85 patients were included in this study. There were 39 patients in the RATS group, including 25 females and 14 males, with an average age of 47.6±13.0 years, and 46 patients in the VATS group, including 14 males and 32 females, with an average age of 45.3±14.7 years. All patients completed the operation successfully. The hospitalization cost in the RATS group was significantly higher than that in the VATS group (P<0.001), and the white blood cell count and neutrophilic granulocyte percentage on the first day after operation in the RATS group were lower than those in the VATS group, and the differences were statistically significant (P<0.05). The operative time, intraoperative bleeding, postoperative hospital stay, white blood cell count and neutrophil percentage on the third postoperative day, visual analogue scale score on the first and third postoperative days, duration of analgesic pump use, postoperative 12 h oxygen saturation (no oxygen inhalation), postoperative down bed time, total thoracic drainage volume, duration of drainage tube retention, and postoperative complication rates were not statistically different between the two groups (P>0.05). There was no perioperative death, conversion to thoracotomy or serious perioperative complications in both groups. ConclusionRATS resection of posterior mediastinal tumor via lateral thoracic approach is safe and feasible, and its short-term effect is similar to that of VATS via lateral thoracic single-hole approach. It is worth further comparative study to explore its benefit and cost performance.
