Objective To explore the influencing factors for pulmonary infection after radical resection of colon cancer. Methods A cohort study included 56 patients who underwent radical resection of colon cancer in People’s Hospital of Daye City from Oct. 2014 to Oct. 2016 were followed-up prospectively, to observe the occurrence of pulmonary infection, and collectting the related factors for pulmonary infection in addition. Results The clinical data of 53 patients were finalized and the clinical data of these patients were complete. Among them, 13 patients suffered from pulmonary infection after radical resection of colon cancer, and 40 patients had no obvious exacerbation and no complicated pulmonary infection. Results of logistic regression showed that, value of forced expiratory volume in1 second/forced vital capacity (OR=1.174, P=0.033), operative time (OR=1.638, P=0.012), levels of postoperative copeptin (OR=1.328, P=0.032), and procalcitonin (OR=1.465, P=0.042) were risk factors for pulmonary infection after radical resection of colon cancer. Receiver operating characteristic curve (ROC) showed that, operative time was 6.207-hour, postoperative copeptin level was 10.420 pmol/L, and the postoperative procalcitonin level was 3.676 ng/mL, which had the best predictive effect on predicting pulmonary infection after radical resection of colon cancer. Conclusions Value of forced expiratory volume in 1 second/forced vital capacity, operative time, levels of copeptin and procalcitonin after operation are the independent influencing factors for pulmonary infection after radical resection of colon cancer, and it has best prognostic outcome when the operative time is 6.207-hour, postoperative copeptin level is 10.420 pmol/L, and the postoperative procalcitonin level is 3.676 ng/mL.
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.
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.
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 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.
Patients with locally advanced thyroid cancer often face challenges in achieving radical surgery during initial diagnosis. This has become a significant hurdle in the treatment of thyroid cancer. With the continuous development of systemic therapy for thyroid cancer, several studies have demonstrated that neoadjuvant therapy can shrink tumors in some patients, thereby increasing the chances of complete resection and improving prognosis. Targeted therapy plays a crucial role as a core component of neoadjuvant treatment. Simultaneously, the potential efficacy of immunotherapy has gained attention, showing promising prospects. We aim to summarize the research progress and existing issues regarding neoadjuvant therapy for locally advanced thyroid cancer. We look forward to more high-quality clinical studies providing robust evidence for neoadjuvant therapy in locally advanced thyroid cancer, expanding the breadth of treatment options.
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 investigate the strategy of treatment and prevention of hemorrhage after radical resection of hilar cholangiocarcinoma. Method Reviewing the related literatures at home and abroad in recent years, to summarize the progress of treatment and prevention of hemorrhage after radical resection of hilar cholangiocarcinoma. Results We should clear the postoperative bleeding time, extent, cause, and location, to help the clinician to choose the appropriate timing of intervention and treatment. The patients with early hemorrhage and mild degree hemorrhage could be treated conservatively. If patients with severe hemorrhage and hemodynamic disorders, surgical intervention must be decisive. Patients with late hemorrhage would have serious consequences, and these patients should receive interventional or surgical treatment as early as possible. Conclusions For patients with hilar cholangiocarcinoma after radical resection, doctors need to do accurate preoperative evaluation, meticulous operation, and intensive management after operation, to reduce the incidence of hemorrhage after radical resection of hilar cholangiocarcinoma. If the postoperative hemorrhage occurs, the cause, location, time, and degree of hemorrhage should be clearly defined to facilitate clinicians to make rapid clinical decisions and to develop treatment programs.
ObjectiveTo investigate the feasibility, safety and clinical effect of total laparoscopic radical resection of hilar cholangiocarcinoma.MethodsRetrospectively summarized the 14 patients with hilar cholangiocarcinoma, who underwent total laparoscopic radical resection of hilar cholangiocarcinoma in the Affiliated Hospital of Xuzhou Medical University from April 2016 to June 2018. Collected the clinical data of those patients, including 7 cases of Bismuth type Ⅰ, 5 cases of Bismuth type Ⅱ, and 2 cases of Bismuth type Ⅲb.ResultsTotal laparoscopic radical resection of hilar cholangiocarcinoma were performed successfully in all 14 patients. The operative time was 190–400 min (median time of 285 min) and the amount of intraoperative blood loss was 100–500 mL (median amount of 175 mL). There was no death case during the perioperative period. Postoperative pathological results showed that all cases accorded with bile duct adenocarcinoma, resection margins of them were negative, amount of lymph node was detected 6–15 per case (median amount of 8 per case), and 3 patients were inspected with peritumoral lymph node metastasis. Two patients were combined with postoperative bile leakage, one of whom was complicated with an abdominal infection, and both were cured and discharged after conservative treatment. All patients were followed-up regularly within 3–24 months (median followed-up period of 16 months). One of them recurred within 12 months after the operation. The remaining patients have survived well so far.ConclusionUnder the operation of the experienced surgeon, total laparoscopic radical resection of hilar cholangiocarcinoma is safe, feasible and effective in the short term.
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.
