We reviewed the clinical studies on drug therapy for gallbladder cancer and expounded on the current situation of conversion therapy for gallbladder cancer. Gallbladder cancer was usually diagnosed late, with high malignancy, low surgical resection rate, and poor prognosis. With the development of conversion therapy, systemic therapy combined with radical resection had effectively improved the surgical resection rate and prognosis of gallbladder cancer patients. At present, most of the published conversion therapies for gallbladder cancer were mainly retrospective researches, lacking large multicenter prospective research, and the treatment plan was still based on chemotherapy, lacking the research of targeted therapy in combination with immunotherapy. It is expected that more high-quality clinical trials can be made first-line recommendations for the conversion therapy of gallbladder cancer.
Objective To analyze clinical value of early enteral nutrition following radical resection of gastric cancer. Methods Seventy-six patients with gastric cancer underwent radical resection from May 1, 2016 to July 1, 2016 in the West China Hospital of Sichuan University were included according to the inclusion criteria and exclusion criteria, then were randomly divided into observation group (36 cases) and control group (40 cases). The patients in the observation group received the enteral nutrition on day 2 following the surgery, in the control group received the conventional management. The gastrointestinal recovery and the adverse reaction were compared in these two groups. The preoperative and postoperative laboratory indicators and the body weight of the patients in both groups were analyzed. Results ① The general data such as age, gender, and body weight had no significant differences in these two groups (P>0.05). ② The first anus exhaust time and the first defecation time of the observation group were significantly shorter than those of the control group (P<0.05). ③ The adverse reaction rate of the observation group was significantly lower than that of the control group (P<0.05). ④ On admission, the serum albumin, urea nitrogen, creatinine, and lymphocyte count had no significant differences in these two groups (P>0.05). On day 5 after the operation, the serum albumin of the observation group was significantly higher than that of the control group (P<0.05). ⑤ The body weight had no significant difference in these two groups before the operation (P>0.05), which in the observation group was significantly heavier than that of the control group on day 30 after the operation (P<0.05). Conclusion Preliminary results of limited cases in this study show that early enteral nutrition following radical resection of gastric cancer is safe and effective, it could promote gastrointestinal function resumption and effectively improve nutritional status.
Objective To explore the feasibility and short-term effectiveness of the modified radical resection and reconstruction in the treatment of malignant proximal humerus tumor. Methods The relevant anatomic data from 30 normal adult shoulder joint MRI were measured to analyze the feasibility of modified radical resection and reconstruction surgery in the treatment of malignant proximal humerus tumor. Five patients with malignant proximal humerus tumor were treated by using the modified radical resection and reconstruction surgery between March 2012 and January 2016. There were 1 male and 4 females, aged from 9 to 69 years (median, 46 years). There were 4 cases of osteosarcoma (Enneking IIA in 2 cases and Enneking IIB in 2 cases) and 1 case of metastatic carcinoma (moderately differentiated adenocarcinoma). The disease duration was 7 to 12 months (mean, 9 months). Recurrence of tumor was observed after operation, and the shoulder function was assessed according to Enneking skeletal muscle tumor function scoring system. Results Radiographic results showed that modified radical resection and reconstruction surgery was feasible, which was in allowable range of the maximum longitudinal diameter ( < 29.8 mm) and depth ( < 4 mm). The operation was successfully completed in all 5 cases, and pathological examination suggested that purposes of radical resection had achieved. All patients were followed up 3 to 49 months (mean, 15.6 months). One patient had local recurrence at 12 months after operation, and a shoulder joint amputation was performed; the other 4 patients had good prosthesis survival. At last follow-up, the function of the shoulder joint was obviously recovered when compared with preoperative function; Enneking's skeletal muscle tumor function score was 25.8 points (range, 24 to 27 points). Conclusion Modified radical resection and reconstruction surgery is feasible for the treatment of proximal humerus tumor, and it can maintain a good early shoulder function.
ObjectiveTo explore the risk factors of perioperative severe complications (Clavien-Dindo grade Ⅲ and above) after laparoscopic radical resection of colorectal cancer (CRC). MethodsThe clinicopathologic data of CRC patients who met the inclusion and exclusion criteria treated in the Shaanxi Provincial People’s Hospital from January 2018 to December 2020 were retrospectively analyzed. The univariate and multivariate logistic analyses were used to explore the risk factors of perioperative severe complications after the laparoscopic radical resection of CRC. ResultsAtotal of 170 eligible patients were included in this study, and the postoperative complications occurred in 45 patients, 24 of whom were severe complications. The univariate analysis results showed that the age (P<0.001), body mass index (BMI, P=0.047), age adjusted Charlson complication index (aCCI) score (P=0.002), American Association of Anesthesiologists (ASA) classification (P<0.001), prognostic nutritional index (PNI, P=0.011), preoperative anemia (P=0.011), operation numbers of surgeon (P=0.003), and operation time (P=0.026) were related to the perioperative severe complications in the patients underwent the laparoscopic radical resection of CRC. The statistic indexes of univariate analysis (P<0.05) combined with indexes of clinical significance were included in the multivariate analysis, the results showed that the ASA classification Ⅲ– Ⅳ (OR=3.536, P=0.027), BMI ≥25 kg/m2 (OR=3.228, P=0.031), preoperative anemia (OR=2.876, P=0.049), operation numbers of surgeon <300 (OR=0.324, P=0.046), and the operation time ≥300 min (OR=3.480, P=0.020) increased the probability of perioperative severe complications in the patients underwent the laparoscopic radical resection of CRC. ConclusionsThe results of this study suggest that clinicians should pay attention to the perioperative management of patients with CRC, such as adequately evaluating the preoperative status of patients by ASA classification, PNI, and aCCI to adjust the malnutrition of patients; after operation, the patients with BMI ≥25 kg/m2 and operation time more than 300 min should be paid more attention. At the same time, the surgeon should continuously accumulate the operation numbers and improve the operation proficiency so as to reduce the occurrence of perioperative severe complications after laparoscopic radical resection of CRC.
Objective To evaluate the long-term efficacy of extended and standard surgery for carcinoma of head of pancreas by using meta-analysis. Methods Related articls （1990-2012） were searched in Pubmed， WOS， Embase， WanFang， SinoMed， and CNKI. Study on quality of these literatures were evaluated by using the Jadad score. The patients with pancreatic head carcinoma underwent extended radical resection and standard radical resection were classified to treatment group and control group， respectively. The mortality， morbidity， and survival rates of 1-， 3-， and 5-year after operation in the two groups were evaluated by using meta-analysis. Results A total of 11 studies fitted the selection crit-eria， including 744 patients. Among them 357 cases were in standard radical resection group and 387 cases in the extended radical resection group. The results of meta-analysis showed that： ①The morbidity after operation did not significantly differed between the extended radical resection group and standard radical resection group （OR=1.360， 95% CI=0.990-1.870， P=0.050）. ②The mortality of the two groups did not significantly differed （OR=0.870， 95% CI=0.430-1.760，P=0.700）. ③There were no significant differences in survival rates of 1-， 3-， and 5-year between the two groups （OR=0.880， 95% CI=0.450-1.720， P=0.710；OR=0.940， 95% CI=0.590-1.480，P=0.710；OR=1.000， 95% CI=0.600-1.67， P=1.000）. Conclusion Compared with standard radical resection， extended radical resection can not improve the survival rates of 1-， 3-， and 5-year after operation， and can’t reduce the mortality and morbidity after operation
Objective To summarize the application and progress of common autologous organ transplantation (AOT) techniques. Method A literature review and summary of previous and recent studies on common AOT was performed, including autologous liver transplantation, autologous kidney transplantation and intestinal autotransplantation techniques. Results AOT solved the issues of bleeding that cannot be controlled by in vivo resection of lesions, difficulties in vascular reconstruction, and the inability to radically resect lesions, and extended the indications for treatment of partially diseased conditions. Conclusions The AOT technique has an ameliorating effect on the tight donor situation in China, providing more potential donors. And the application of the AOT technique effectively avoids the usage of postoperative immunosuppressive drugs and the progression of lesions due to waiting for allogeneic organ transplantation. However, the clinical benefit in malignant tumors remains to be further investigated.
Objective To investigate the impact of conversion to open in laparoscopic rectal cancer radical resection (LRR) on postoperative recovery. Methods The data from Feb. 2003 to Feb. 2007 of 176 cases who were given LRR and 32 cases receiving conversion in LRR (CRR) were analyzed retrospectively, and were compared about operation time, hospitalization time, hospitalization expenses, intraoperative blood loss, recovery time of bowel movement and postoperative complications with 59 cases of open rectal cancer radical resection (ORR). Results There were no differences among LRR, CRR and ORR about operation time, hospitalization time, intraoperative blood loss and recovery time of bowel movement (Pgt;0.05). The hospitalization expenses of LRR and CRR were higher than that of ORR (P=0.001, P=0.001), there was no difference between CRR and LRR (P=0.843). But the postoperative complications rate of ORR was higher than those of LRR and CRR （P=0.023,P=0.004）. Conclusion Compared with ORR, LRR has relatively conversion rate, and then increases the hospitalization expenses.
ObjectiveTo explore the reasonable and feasible safe distance for radical resection of hepatic alveolar echinococcosis (HAE). MethodsLiver samples were collected prospectively from 20 HAE patients (from Jan. 2019 to Jun. 2019) undergoing liver resection in West China Hospital of Sichuan University. A total of three samples containing lesion and adjacent liver tissue were collected from each patient, which were divided into lesion group, 0 to0.5 cm liver tissue group (contained 0.5 cm), 0.5 to 1.0 cm liver tissue group (contained 1.0 cm), 1.0 to 1.5 cm liver tissue group (contained 1.5 cm), and 1.5 to 2.0 cm liver tissue group (contained 2.0 cm). Comparisons of the Cox1 expressionand the liver fibrosis area between HAE lesion and adjacent liver tissues were performed. ResultsBoth expression of Cox1 and fibrosis area in HAE lesion were significantly higher than those in the adjacent liver tissues (P<0.000 1). However, there was no significant difference among the four kinds of adjacent liver tissues (P>0.05). There was a significant positive correlation between the expression of Cox1 and the fibrosis area both in HAE lesion and adjacent liver tissues (P<0.05). ConclusionsBoth the expression of Cox1 and degree of the liver fibrosis are significant higher in HAE lesion comparing to adjacent liver tissues, however, no significant difference is found among adjacent liver tissues. Consequently, a safe distance of 0.5 cm may be reasonable and feasible on the basis of the criteria for sample collection in the study.
ObjectiveTo introduce the current study of the metastatic mode and operation methods in advanced gallbladder carcinoma. MethodsThe literatures about metastatic mode and operation methods of advanced gallbladder carcinoma in recent 5 years were reviewed.ResultsLymph node and hepatic invasion were the main mode of advanced gallbladder carcinoma. The Japanese Society of Biliary Surgery （JSBS） classification to gallbladder carcinoma was more reasonable than the UICC classification. The survival rate after radical resection was higher than that after cholecytectomy in patients with T2n1-2M0. In the patients that tumor extended adjacent organs but the lymph node metastatic localized within n2, extended radical resection provided a survival advantage. If the patients’ tumor was not resectable or who had lymph node metastasis beyond n3, the benefit of extended radical resection seemed limited.ConclusionIn the carefully selected patients, extended radical resection will improve the prognosis of advanced gallbladder carcinoma.
Objective To understand status of technical realization, present development, faced problems, and application prospects of reduced-port laparoscopic surgery for rectal cancer, and to analyze safety and feasibility so as to provide theoretical and practical basis for clinical application and promotion. Method By searching the databases such as Medline, Embase, and Wanfang, etc., the relevant literatures about reduced-port laparoscopic surgery for rectal cancer were collected and reviewed. Results At present, the most common reduced-port laparoscopic surgery was the 1-port laparoscopic surgery, 2-port laparoscopic surgery, and 3-port laparoscopic surgery. The 1-port laparoscopic surgery had the effects of minimal invasiveness and cosmesis, but it was difficult to perform. The 2-port laparoscopic surgery for rectal cancer preserved as far as possible the effect of minimal invasiveness, the difficulty of procedure was reduced greatly, which was easy to be learnt and promoted. The experience of the 3-port laparoscopic surgery for rectal cancer contributed to the technical development of the 1-port laparoscopic surgery, with no need for the assisted incision for intraoperative specimen. The reduced-port laparoscopic surgery for rectal cancer was technically feasible and safe, which possessed the equal or better short-term outcomes as compared with the conventional 5-port laparoscopic or open surgery beside the radical resection for rectal cancer. However, the stringent technique for the laparoscopic surgery was necessary and it needed to overcome the learning curve. Conclusions Reduced-port laparoscopic surgery has some obvious advantages in minimal invasiveness, cosmesis, and enhanced recovery. More large-sample, multi-center, randomized controlled trials are eager to further confirm safety, effectiveness, and feasibility of reduced-port laparoscopic surgery for rectal cancer.
