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.

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 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 operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. ConclusionThe tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.
ObjectiveTo investigate effect of recurrent laryngeal nerve monitoring in video-assisted thyroidectomy for huge thyroid nodules. MethodsThe clinical data of 158 patients with huge thyroid nodules underwent videoassisted thyroidectomy from January 2013 to June 2015 were analyzed retrospectively, the recurrent laryngeal nerves were monitored in 79 cases (monitoring of recurrent laryngeal nerve group) while the recurrent laryngeal nerves were not monitored in the other patients (non-monitoring of recurrent laryngeal nerve group). The operative time, blood loss, postoperative drainage, postoperative hospital stay, and the incidences of transient and permanent recurrent laryngeal nerve injury were observed between these two groups. ResultsThe video-assisted miniincision thyroidectomy was successfully completed in these 158 cases. Compared with the non-monitoring of recurrent laryngeal nerve group, the operative time (min) was shorter (76.2±23.4 versus 89.2±29.8, P < 0.05), the blood loss and the postoperative drainage were less (16.3±13.6 versus 20.6±10.7, P < 0.05; 20.7±9.6 versus 25.5±9.1, P < 0.05) in the monitoring of recurrent laryngeal nerve group. But the postoperative hospital stay (d) had no significant difference between the monitoring of recurrent laryngeal nerve group and the non-monitoring of recurrent laryngeal nerve group (3.2±1.3 versus 3.3±1.9, P > 0.05). Eight weeks later, the incidence of transient recurrent laryngeal nerve injury in the monitoring of recurrent laryngeal nerve group was significantly lower than that in the non-monitoring of recurrent laryngeal nerve group [5.6% (5/90) versus 21.8% (17/78), P < 0.05], while the incidence of permanent nerve injury had no statistical difference between the monitoring of recurrent laryngeal nerve group and the non-monitoring of recurrent laryngeal nerve group [0(0/90) versus 1.3% (1/78), P > 0.05]. ConclusionRecurrent laryngeal nerve monitoring under video-assisted thyroidectomy for huge thyroid nodules could effectively reduce incidence of nerve injury and shorten operation time.
