AIM: To investigate preoperative factors associated with poor shore-term outcome after resection for multi- nodular hepatocellular carcinoma (HCC) and to assess the contraindication of patients for surgery, METHODS: We retrospectively analyzed 162 multi- nodular HCC patients with Child-Pugh A liver function who underwent surgical resection. The prognostic significance of preoperative factors was investigated by univariate analysis using the log-rank test and by multivariate analysis using the Cox proportional hazards model. Each independent risk factor was then assigned points to construct a scoring model to evaluate the in- dication for surgical intervention. A receiver operating characteristics (ROC) curve was constructed to assess the predictive ability of this system.RESULTS: The median overall survival was 38.3 mo (range: 3-80 too), while the median disease-free sur- vival was 18.6 mo (range: 1-79 too). The 1-year mor- tality was 14%. Independent prognostic risk factors of 1-year death included prealburnin 〈 170 rng/L [hazard ratio (HR): 5.531, P 〈 0.001], alkaline phosphatase 〉 129 U/L (HR: 3.252, P = 0.005), α fetoprotein 〉 20 μg/L (HR: 7.477, P = 0.011), total tumor size 〉 8 cm (HR: 10.543; P 〈 0.001), platelet count 〈 100×109/L (HR: 9.937, P 〈 0.001), and y-glutamyl transpeptidase 〉 64 U/L (HR: 3.791, P 〈 0.001). The scoring model had a strong ability to predict 1-year survival (area under ROC: 0.925, P 〈 0.001). Patients with a score ≥5 had significantly poorer short-term outcome than those with a score 〈 5 (1-year mortality: 62% vs 5%, P 〈 0.001; 1-year recurrence rate: 86% vs 33%, P 〈 0.001). Patients with score ≥5 had greater possibility of microvascular invasion (P 〈 0.001), poor tumor dif- ferentiation (P = 0.003), liver cirrhosis with small nod- ules (P 〈 0.001), and intraoperative blood transfusion (P = 0.010). CONCLUSION: A composite preoperative scoring model can be used as an indication of prognosis of HCC patients after surgical resection. Resection should be considered with caution in patients with a score ≥5, which indicates a contraindication for surgery. 展开更多

AIM:To investigate the proficiency level reached in laparoscopic splenectomy using the learning curve method.METHODS:All patients in need of splenectomy for benign causes in whom laparoscopic splenectomy was attempted by a single surgeon during a time period of 6 years were included in the study (n=33). Besides demographics, operation-related variables and the response to surgery were recorded. The patients were allocated to groups of five, ranked according to the date of the operation. Operation duration, complications, postoperative length of stay, conversion to laparotomy and splenic weight were then compared between these groups.RESULTS: There was a significant difference regarding operation times between the groups (P = 0.001). An improvement was observed after the first 5 cases. The learning curve was flat up to the 25th case. Following the 25th case the operation times decreased still further. There was no difference between the groups regarding the other parameters.CONCLUSION: Unlike the widely accepted "L" shape, the learning curve for laparoscopic splenectomy is a horizontal lazy "S" with two distinct slopes. Privileges may be granted after the first 5 cases. However proficiency seems to require 25 cases. 展开更多

It always combins with trunk imbalance in coronal and sagittal contour. Besides complex pathological changes, cardiopulmonary deficits and other concomitant diseases increase treatmental difficulties. So the treatment of severe scoliosis is always a great challenge to spine surgeon.Methods:Thirty-six patients with severe scoliosis received one stage posterior correction followed by anterior release during July 1997 to January 2003, including 9 males and 27 females. Mean age was 17.2 years. Of them, 33 was idiopathic scoliosis and 3 was neurofibromatosis scoliosis( Cobb angle: 85-116 degree); 20 cases were abnormal in sagital plane. Three-dimensional devised instrumentation were applied such as CD, CD-Horizon, TSRH or Isola in posterior procedure followed by anterior release during the same anesthesia. 31 cases of this group received thoracic plasty.Results: The correction in the frontal plane achieved an average of 48.5%. In the sagittal plane, the pathological shape of the spine was reduced and distinctly ameliorated. 80.6% of the patients maintained or achieved balance of sagittal plane. There were no complications of severe neurological deficit, hook displacement, rod broken, and deep infection at follow-up. One case occurred traumatic pleurisy after operation and another appeared pseudarthrosis 2 years later. One case demonstrated imbalance 11 months after operation. One patient was presented loss of correction more than 10 degree at one year follow-up and 5.2 degree in average.Conclusion:The study indicates that the one stage posterior correction combined with anterior release in treatment of severe scoliosis can achieve satisfactory correction. Appropriate choice of cases, preoperational detailed assessment and application of SEP and wake-up test during operation can possibly reduce severe complication. The long-term outcomes still need further observation. 展开更多

Objective: McKeown esophagectomy followed by cervical and abdominal procedures has been commonly used for invasive esophageal carcinoma. This minimally-invasive operative procedure in the lateral prone position has been considered to be the most appropriate method. We describe our experiences in minimally invasive McKeown esophagectomy (MIME) for esophageal cancer. Methods: Between March 2016 and February 2018, a total of 82 patients underwent MIME by a single group in our department (a single center). All procedure, operation, oncology, and complication data were reviewed. Results: All MIME procedures were completed successfully, with no conversions to open surgery. The median operative time was 260 min, and median blood loss was 100 ml. The average number of total harvested lymph nodes was 20.1 in the chest and 13.5 in the abdomen. There were no deaths within 30 postoperative days. Twenty cases (24.4%) developed postoperative complications, including anastomotic leak in 4 (4.9%), single lateral recurrent nerve palsy in 4 (4.9%), bilateral recurrent nerve palsy in 1 (1.2%), pulmonary problems in 3 (3.7%), chyle ~eak in 1 (1.2%), and other complications in 7 (including pleural effusions in 4, incomplete ileus in 2, and neck incision infection in 1; 8.54%). Average postoperative hospitalization time was 12 d. Blood loss, operation time, morbidity rate, and the number of harvested lymph nodes were analyzed by evaluating learning curves in different periods. Significant differences were found in operative time (P=-0.006), postoperative hospitalization days (P=0.015), total harvested lymph nodes (P=0.003), harvested thoracic lymph nodes (P=0.006), and harvested abdominal lymph nodes (P=0.022) among different periods. Conclusions: Surgical outcomes following MIME for esophageal cancer are safe and acceptable. The MIME procedure for stages I and II could be performed proficiently and reached an experience plateau after approximately 25 cases. 展开更多

Background:Early recurrence has been reported to be predictive of a poor prognosis for patients with perihilar cholangiocarcinoma(pCCA)after resection.The objective of our study was to construct a useful scoring system to predict early recurrence for Bismuth–Corlette type IV pCCA patients in clinic and to investigate the value of early recurrence in directing post-operative surveillance and adjuvant therapy.Methods:In total,244 patients who underwent radical resection for type IV pCCA were included.Data on clinicopathological characteristics,perioperative details and survival outcomes were analyzed.Survival curves were generated using the Kaplan–Meier method.Univariate and multivariate logistic-regression models were used to identify factors associated with early recurrence.Results:Twenty-one months was defined as the cutoff point to distinguish between early and late recurrence.Univariate and multivariate analysis revealed that CA19-9 level>200 U/mL,R1 resection margin,higher N category and positive lymphovascular invasion were independent predictors of early recurrence.The scoring system was constructed accordingly.The early-recurrence rates of patients with scores of 0,1,2,3,4,and 5 were 23.9%,38.7%,60.0%,78.6%,83.4%,and 100%,respectively.Adjuvant therapy was significantly associated with higher overall survival rate for patients with early recurrence,but not for those with late recurrence.Patients in the early-recurrence group with scores2 had better prognoses after adjuvant therapy.Conclusions:A simple scoring system using CA19-9 level,N category,resection margin and lymphovascular invasion status could predict early recurrence,and thus might direct post-operative surveillance and adjuvant therapy for patients with type IV pCCA. 展开更多
