ObjectiveTo summarize the clinical experience of 58 operations for biliary malignant tumor with da Vinci surgical system. MethodsFrom January 2009 to October 2010, 180 patients with hepatopancreaticobiliary and gastrointestinal disease underwent robotic surgeries by using da Vinci surgical system, including 58 patients with biliary malignant tumor. The case distribution, intra and postoperative data were analyzed. ResultsOf 58 patients, 3 patients with intrahepatic bile duct cystadenocarcinoma received wedge resections of liver. In 36 patients with hilar cholangiocarcinoma, anatomical left hemihepatectomies were performed in 3 cases, resection of extrahepatic duct and gallbladder bridge type biliary revascularization in 3 cases, resection of extrahepatic duct and biliary-enteric Roux-en-Y anastomosis in 14 cases, tumor resection and revascularization of hepatic portal bile duct in 1 case, palliative external drainage of intrahepatic bile duct in 5 cases, and Y-internal drainage of hepatic portal in 10 cases. In 10 patients with gallbladder carcinoma, resection of extrahepatic duct and gallbladder and biliaryenteric Roux-en-Y anastomosis in 2 cases, cholecystectmy in 3 cases, cholecystectmy and external drainage of intrahepatic bile duct in 1 case, cholecystectmy and Y-internal drainage by suspension of hepatic portal in 4 cases. A patient with middle bile duct cancer received radical resection of cholangiocarcinoma and biliary-enteric Roux-en-Y anastomosis. Of 8 patients with distal bile duct cancer, Whipple procedure were performed. Of 58 patients, 2 cases converted to hand-assistant procedure (3.4%). For all patients, operation time was (6.18±1.71) h, blood loss was (116.66±56.06) ml, blood transfusion was (85.55±38.28) ml, ambulation time was (9.10±2.91) h, feeding time was (14.95±4.35) h, and hospital stay was (12.81±4.29) d. Postoperative complications occurred in 8 cases (13.8%), including bile leakage (3 cases), wound bleeding (1 case), pancreatoenteric anastomotic leakage (2 cases), pulmonary infection (1 case), and renal failure (1 case). Of these 8 cases, 6 cases recovered smoothly and 2 cases die of severe pulmonary infection and renal failure after conservative treatment (3 or 4 weeks), therefore, the mortality of patients was 3.4%. In 36 patients with hilar cholangiocarcinoma, 19 cases died (on 2 monthes 4 cases, on 6 monthes 5 cases, on 10 monthes 8 cases, and on 12 monthes 2 cases after operation), 11 cases survival well (gt;26 monthes 4 cases, gt;22 monthes 3 cases, and gt;19 monthes 4 cases), and 6 cases required hospitalization. Of 10 patients with gallbladder carcinoma, 7 cases died (on 3 monthes 1 case, on 5 monthes 1 case, on 8 monthes 1 case, on 11 monthes 3 cases, and on 12 monthes 1 case after operation) and 3 cases survival (gt;17 monthes 2 cases, gt;13 monthes 1 case). In 8 cases undergoing pancreatoduodenectomy, 5 cases died (on 4 monthes 2 cases, on 6 monthes 2 cases, and 10 monthes 1 case after operation) and 3 cases survived well over 2 years. Three patients with intrahepatic bile duct cystadenocarcinoma survived over 1 year. Conclusionsda Vinci surgical system can carry out all kinds of surgery for biliary malignant tumor, especially prominent in the complicated surgeries for hepatic portal, which breaks through the restricted area of laparoscope in hepatobiliary malignant tumor.
This article reviews the development and progress in the field of limb salvage treatment, surgical techniques, and function reconstruction of pelvic malignant tumors in China in the past 30 years. Based on the surgical classification of pelvic tumor resection in different parts, the development of surgical techniques and bone defect repair and reconstruction methods were described in detail. In recent years, in view of the worldwide problem of biological reconstruction after pelvic tumor resection, Chinese researchers have systematically proposed the repair and reconstruction methods and prosthesis design for bone defects after resection of different parts for the first time in the world. In addition, a systematic surgical classification (Beijing classification) was first proposed for the difficult situation of pelvic tumors involving the sacrum, as well as the corresponding surgical plan and repair and reconstruction methods. Through unremitting efforts, the limb salvage rate of pelvic malignant tumors in China has reached more than 80%, which has preserved limbs and restored walking function for the majority of patients, greatly reduced surgical complications, and achieved internationally remarkable results.
A large amount of research evidence has shown a correlation between cerebral infarction and malignant tumors, and malignant-tumor-related embolic stroke is the main type of malignant-tumor-related cerebral infarction. Hypercoagulation is considered to be the main mechanism. However, due to the complexity of the pathogenesis, the optimal diagnosis, treatment, and prevention strategies remain unclear. This review summarizes the published literature on the concepts, mechanisms, clinical manifestations, laboratory and imaging examinations, treatment and prevention of malignant-tumor-related embolic cerebral infarction, to clearly understand this disease and provide ideas for early recognition, reasonable diagnosis and treatment, improvement of prognosis, and further research of this disease.
To evaluate effect of recombinant human growth hormone (rhGH) on immunologic function in patients with gastrointestinal malignant tumor (GIMT). Before and 3 weeks after surgical treatment and administration of rhGH, the amount of T lymphocyte subset (T-LS) and soluble interleukin 2 receptor (sIL-2R) level were measured in 12 patients with GIMT, which were compared with 20 cases of normal control and 18 cases of GIMT treated by surgery alone. Result: ①In all GIMT patients, the serum CD＋3, CD＋4 level and the ratio of CD＋4/CD＋8 were lower than normal control and the sIL2R level was much higher; ②After operation, the serum CD＋3, CD＋4 level and the ratio of CD＋4/CD＋8 of all patients increased, the serum sIL2R level decreased; ③In patients recieved rhGH, the serum CD＋3, CD＋4 level and the ratio of CD＋4/CD＋8 were much more increased and the serum sIL-2R level much more decreased than those of surgery alone group. Conclusion: rhGH can enhance the immunologic function of patients with GIMT.

The follow-up ranged from 7 to52 onths,with an average of 24.6 months. Postoperative complication included 1 case of pneumothorax, one case of shoulder incision skin part necrosis and 1 case of clavicle stump raising and pierce skin with shallow infection. No complication of postoperative incision deeply infection, nerve damage and prosthesis exposure or dislocation occurred. According to the scoring system of JOA(Japan orthopaedics association), the average score was 65 (60 to 72). The flexion and extension function of elbow joint recovered to normal. Conclusion The replacement of inverttype artificial total scapula and shoulder joint prosthesis is an efficacious method for the treatment of malignant tumor in shoulder. There are advantages of numerous adaption, wide range of motion and goodstability. It can not only reserve arm but also rehabilitate function.
ObjectiveTo investigate the effectiveness of free anterolateral thigh Kiss flap in repair of large scalp defect after malignant tumor resection.MethodsBetween December 2012 and December 2016, 18 patients with large scalp defect after malignant tumor resection were treated. There were 16 males and 2 females with an average age of 52.6 years (range, 43-62 years). There were 17 cases of squamous carcinoma and 1 case of dermatofibrilsarcoma protuberan. The size of scalp defect ranged from 15 cm×10 cm to 17 cm×12 cm after resection of tumors. The scalp defects were repaired with the free anterolateral thigh Kiss flap. And the size of flap ranged from 15 cm×6 cm to 20 cm×8 cm. The skull was completely resected in 2 cases, and repaired with Titanium mesh. The sizes of skull defects were 12 cm×10 cm and 10 cm×8 cm. The donor site was sutured directly.ResultsEighteen flaps survived with primary healing of wounds; and healing by first intention was obtained at the donor sites. One patient died because of intracranial metastasis at 5 months after operation, and no local recurrence occurred in the other 17 patients. The follow-up time ranged from 6 months to 4 years (mean, 26.6 months). The results of both appearance and function were satisfactory, without ulceration during follow-up. No obvious scar was found at donor sites and no obvious impairment was observed after harvesting free anterolateral thigh flap.ConclusionLarge scalp defects after malignant tumor resection can be effectively repaired by free anterolateral thigh Kiss flap. The donor site can be sutured directly, without skin grafting, thus avoiding the secondary donor site.
ObjectiveTo review the clinical experience and evaluate the results in patients who underwent caudate lobectomy for malignant tumor at caudate lobe of liver. MethodsClinicopathological characteristics of 51 patients who underwent caudate lobectomy because of malignant tumors at caudate lobe of liver in our hospital from May 2007 to December 2013 were reviewed retrospectively, and operative detail, complication rate, and survival rate were described. ResultsThe cancer were resected successfully in 51 patients with malignant tumors at caudate lobe of liver. Thirty patients were performed isolated caudate lobectomy and 21 patients performed combined lobectomy. Of the 51 patients, 9 patients were treated with retrograde caudate lobectomy. The operation time was 180.0-360.0 min, with the average value of 244.0 min. The bleeding volume was 400.0-1 000.0 mL, with the average value of 630.0 mL. In all patients, there was no perioperative death and no postoperative bleeding happened, and 17 patients who suffered from interrelated complications were cured or got better by conservative treatments. Fifty-one patients were followed up for 6-60 months, and the median survival time was 38.0 months. During the follow-up period, 29 patients dead, 21 patients suffered from recurrence, and 12 patients suffered from metastasis. The cumulative survival rates of 1-, 3-, and 5-year were 76.1%, 54.7%, and 31.8% respectively after caudate lobectomy. ConclusionThe caudate lobectomy in treatment of malignant tumor at caudate lobe of liver is effective and feasible.
Objective To summarize the treatment and prognosis of malignant tumors with hepatic metastasis. Methods Review and analysis of recent relevant literatures at home and abroad of malignant tumors with liver metastasis, according to the different treatments were summarized. Evaluation of the patients’ clinically curative effect and survival situation was performed under different treatments. Results With the development of imaging and surgical techniques, and deeply understanding of malignant tumor, many malignant tumors with liver metastasis could be found and treated, and previous concept of treatment for malignant tumors with liver metastasis was also fundamentally changed, and radical resection of the primary lesions and liver metastasis was the best way to get clinically curative effect for the patients with malignant tumors with liver metastasis. The treatments of malignant tumors with liver metastasis also included radio frequency ablation (RFA), transarterial chemoembolization (TACE), chemotherapy,125I seed implantation, cryotherapy, stereotactic body radiation therapy (SBRT), laser-induced interstitial thermotherapy (LITT), gene targeting therapy, and so on. Conclusion Now for malignant tumors with liver metastasis, positive surgery and (or) individualized comprehensive treatment are taken more often, and they play positive role to prolong the survival and improve the prognosis of malignant tumors patients with liver metastasis.
ObjectiveTo review the definition, incidence, risk factors, potential pathogenesis, biomarkers, and choice of follow-up treatment strategies of hyperprogressive disease (HPD).MethodDomestic and international literatures were collected to summarize the research progress of HPD in patients with malignant tumors who treated with immune checkpoint inhibitors (ICIs).ResultsThe research types of HPD were scattered, the sample size was limited, the definition standard was different, and there was lack of prospective validation studies. Therefore, the early warning assessment and molecular mechanism of HPD would become the next focus of the study of immunotherapy.ConclusionICIs can greatly improve the survival time of some patients with advanced malignant tumor, although some patients have HPD during treatment, but the incidence is relatively low.
ObjectiveTo summarize the experience in the treatment of infection after limb salvage surgery for malignant tumor around knee joint, and explore the risk factor related to infection after limb salvage surgery.MethodsA clinical data of 212 patients with malignant tumor around the knee joint underwent limb salvage surgery between January 2008 and December 2017 were retrospectively analyzed. Among them, 14 cases had infection after limb salvage surgery. Two cases of acute infection were treated with sensitive antibiotics; 12 cases of chronic infection were treated with debridement and antibiotic bone cement occupying device implantation in the first stage, and prosthesis revision (8 cases), knee joint fusion (2 cases), or amputation (2 cases) in the second stage after infection control. The age, gender, preoperative chemotherapy cycle, bone marrow suppression, serum albumin, hemoglobin, operation time, postoperative drainage time, and blood transfusion volume were analyzed to screen the risk factors related to infection after limb salvage surgery. The infection and tumor recurrence were observed, and the limb function was evaluated by Enneking scoring system.ResultsThe univariate analysis showed that the preoperative chemotherapy cycle, bone marrow suppression, operation time, and postoperative drainage time were the influencing factors of postoperative infection (P<0.05). Multivariate analysis showed that the operation time, preoperative chemotherapy cycle, and postoperative drainage time were risk factors of postoperative infection (P<0.05). Among the 14 patients, 1 patient died of traffic accident at 6 months after the second stage operation, and 13 patients were followed up 12.2-48.0 months (mean, 19.9 months). Two cases of acute infection cured. Among the 11 patients with chronic infection, 2 cases of subluxation of the antibiotic bone cement occupying device after the first stage operation occurred; 9 cases of infection cured and 2 cases recurred. At 12 months after operation, except 1 case died by accident, the Enneking scores of the other 13 patients were 12-26, with an average of 20. At last follow-up, 1 case of lung metastasis was still alive, and no tumor metastasis or recurrence was found in the rest.ConclusionThe time of limb salvage surgery, preoperative chemotherapy cycle, and drainage time after limb salvage surgery are the risk factors of infection after limb salvage surgery. Early etiological examination and drug sensitivity test is the key to the treatment of infection. One-stage debridement combined with antibiotic bone cement occupying device can effectively cure infection and save patients’ limbs.
