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.
ObjectiveTo summarize experiences of diagnosis and treatment of intraperitoneal mass after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in treatment of hepatocellular carcinoma (HCC).MethodThe clinicopathologic data of a 40 years old case of HCC with intraperitoneal mass after ALPPS in the First Affiliated Hospital of Guangxi Medical University were retrospectively analyzed.ResultsThe patient was admitted to this hospital because of abdominal pain and abdominal distension for 5 d. The intraperitoneal mass was found and its nature was not clear on year 1 after ALPPS on admission. After discussion of multidisciplinary team (MDT), the exploratory laparotomy and abdominal tumor resection were planned to perform. The intraperitoneal mass and appendix were removed, the resected tissues were diagnosed as chronic inflammation and retroperitoneal abscess caused by perforation of suppurative appendicitis, respectively. The anti-infection and symptomatic support treatment were strengthened to perform after operation, the patient discharged after recovery. The patient was followed up so far, the general condition was good, and there was no clinical recurrence.ConclusionsFor patient underwent ALPPS, regular follow-up should be paid attention to. If intraperitoneal mass is found and nature is not clear, MDT discussion should be performed so as to make a more reasonable treatment plan. After exclusion of contraindications, surgical treatment should be carried out to furthest benefit patients.
ObjectiveTo analyze and compare the perioperative efficacy difference between full-port Da Vinci robotic surgery and thoracoscopic surgery in patients with mediastinal tumor resection. MethodsThe data of 232 patients with mediastinal tumors treated by the same operator in the Department of Thoracic Surgery of the Second Affiliated Hospital of Harbin Medical University were included. There were 103 (44.4%) males and 129 (55.6%) females, with an average age of 49.7 years. According to the surgical methods, they were divided into a robot-assisted thoracic surgery (RATS) group (n=113) and a video-assisted thoracoscopic surgery (VATS) group (n=119). After 1 : 1 propensity score matching, 57 patients in the RATS group and 57 patients in the VATS group were obtained. ResultsThe RATS group was better than the VATS group in the visual analogue scale pain score on the first day after the surgery [3.0 (2.0, 4.0) points vs. 4.0 (3.0, 5.0) points], postoperative hospital stay time [4.0 (3.0, 5.5) d vs. 6.0 (5.0, 7.0) d] and postoperative catheterization time [2.0 (2.0, 3.0) d vs. 3.0 (3.0, 4.0) d] (all P<0.05). There was no statistical difference between the two groups in terms of intraoperative blood loss, postoperative complications, postoperative thoracic closed drainage catheter placement rate or postoperative total drainage volume (all P>0.05). The total hospitalization costs [51 271.0 (44 166.0, 57 152.0) yuan vs. 35 814.0 (33 418.0, 39 312.0) yuan], operation costs [37 659.0 (32 217.0, 41 511.0) yuan vs. 19 640.0 (17 008.0, 21 421.0) yuan], anesthesia costs [3 307.0 (2 530.0, 3 823.0) yuan vs. 2 059.0 (1 577.0, 2 887.0) yuan] and drug and examination costs [9 241.0 (7 987.0, 12 332.0) yuan vs. 14 143.0 (11 620.0, 16 750.0) yuan] in the RATS group was higher than those in the VATS group (all P<0.05). ConclusionRobotic surgery and thoracoscopic surgery can be done safely and effectively. Compared with thoracoscopic surgery, robotic surgery has less postoperative pain, shorter tube-carrying time, and less postoperative hospital stay, which can significantly speed up the postoperative recovery of patients. However, the cost of robotic surgery is higher than that of thoracoscopic surgery, which increases the economic burden of patients and is also one of the main reasons for preventing the popularization of robotic surgery.
Objective To analyze the feasibility of totally no tube (TNT) in da Vinci robotic mediastinal mass surgery and its significance for fast track surgery. Methods A total of 79 patients receiving robotic mediastinal TNT surgery in the General Hospital of Shenyang Military Command from January 2016 to December 2017 were enrolled as a TNT group; 35 patients receiving robotic mediastinal surgery in General Hospital of Shenyang Military Command from January 2014 to December 2017 and 54 patients receiving thoracoscopic mediastinal surgery during the same period were enrolled as a non-TNT group and a video-assisted thoracoscopic surgery (VATS) group. The muscle relaxation and tracheal intubation/laryngeal masking time, operation time, intraoperative blood loss, postoperative ICU stay, postoperative hospital stay, postoperative visual analogue scale (VAS), hospitalization costs and postoperative complications and other related indicators were retrospectively analyzed among the three groups. Results Surgeries were successfully completed in 168 patients with no transfer to thoracotomy, serious complications (postoperative complications in 9 patients) or death during the perioperative period. All patients were discharged. Compared with the non-TNT group, the TNT group had significantly less muscle relaxation-tracheal intubation/laryngeal masking time, operation time, intraoperative blood loss, VAS pain score, ICU stay, postoperative hospital stay (P<0.01); there was no significant difference in the total cost of hospitalization between the two groups (P>0.05). Between the non-TNT group and the VATS group, there was no significant difference in time of muscle relaxation and tracheal intubation, operation time and ICU stay (P>0.05). The non-TNT group was superior to the VATS group in terms of intraoperative blood loss, VAS pain scores on the following day after operation, chest drainage volume 1-3 days postoperatively, postoperative catheterization time and postoperative hospital stay (P<0.05); but the cost of hospitalization in the non-TNT group was significantly higher (P=0.000). Conclusion The da Vinci robot is safe and feasible for the treatment of mediastinal masses. At the same time, TNT is also safe and reliable on the basis of robotic surgery which has many advantages such as better comfort, less pain, ICU stay and hospital stay as well as faster recovery.

ObjectiveTo discuss the safety, feasibility and short-term clinical efficacy of thoracoscopic anterior mediastinal mass resection in lithotomy position via subxiphoid approach or lateral position via transthoracic approach.MethodsA total of 44 patients suffering anterior mediastinal tumor enrolled, including 21 patients (10 males and 11 females as a trial group) with an average age of 43.6±11.8 years who have been performed thoracoscopic anterior mediastinal tumor resection in lithotomy position via subxiphoid approach and 23 patients (13 males and 10 females as a control group) with an average age of 45.3±10.8 years who have been performed thoracoscopic anterior mediastinal tumor resection in lateral position via transthoracic approach. The clinical efficacy of the two groups was compared.ResultsPostoperative chest drainage time (3.8±1.3 d vs. 5.0±1.8 d, P=0.017), postoperative drainage volume (238.8±66.2 mL vs. 467.2±120.0 mL, P=0.000), postoperative mean visual analogue score at 24 h (2.5±0.9 point vs. 4.9±1.0 point, P=0.000), times of self-pressure analgesic pump (3.7±0.9 vs. 8.4±2.0, P=0.000), duration of postoperative hospital stay (4.7±1.3 d vs. 7.4±3.1 d, P=0.000) and hospitalization cost (34±8 kyaun vs. 44±11 kyuan P=0.001) in the trial group were all better than those in the control group. There was no significant difference between the two groups in surgical duration (59.0±18.1 min vs. 60.4±16.4 min) (P>0.05). During follow-up, no recurrence or metastasis occurred in either group.ConclusionCompared with the lateral position through the transthoracic approach, the lithotomy position through subxiphoid approach of thoracoscopic anterior mediastinal mass resection is safe and feasible, and has certain advantages.
With the adoption of the surgical principles emphasizing minimally invasive, precise, and individualized procedures, the sternum elevation via the subxiphoid approach for thoracoscopic surgery has become an important technique for the resection of anterior mediastinal masses. This method offers significant advantages in terms of increasing surgical field exposure, reducing surgical trauma, alleviating postoperative pain, and improving cosmetic outcomes. To establish a standardized surgical system and promote the consistent implementation of this technique, this consensus integrates the practical experiences of multiple thoracic surgery centers in China and relevant literature reports. It addresses core clinical issues such as surgical indications, preoperative assessment, anesthesia and intraoperative cooperation, key surgical techniques, postoperative management, prevention and treatment of complications, as well as training and quality control systems. The aim is to provide a safer and more effective minimally invasive solution for patients with anterior mediastinal masses and to facilitate the innovation of minimally invasive surgical modalities for the anterior mediastinum.
