ObjectiveTo analyze risk factors of postoperative complications associated with reversal of defunctioning ileostomy in patients with rectal cancer undergoing sphincter preservation surgery. MethodData were collected retrospectively for consecutive patients undergoing defunctioning ileostomy following sphincter preservation surgery for rectal cancer, from January 2014 to December 2014. ResultsOne hundred and thirty patients were included (median time to reversal 132 d, range 39-692 d), of whom 35 patients (26.92%) had postoperative complications after stoma reversal. The main complications included 23 cases of diarrhea, 6 cases of bowel obstruction, 9 cases of incision infection, and 4 cases of perianal eczema. The results of univariate analysis showed that the distant of tumor from anal verge <5 cm (P=0.010), postoperative adjuvant chemotherapy (P=0.002), and time to reversal (P=0.025) were related to the postoperative complications associated with reversal of defunctioning ileostomy in patients with rectal cancer undergoing sphincter preservation surgery. The result of multivariate analysis by using a logistic regression model showed that the time to reversal (OR=1.006, P=0.021) was a significant independent risk factor for it. ConclusionDelay reversal of defunctiong ileostomy might increase risk of postoperative complications associated with reversal of defunctioning ileostomy in patients with rectal cancer undergoing sphincter preservation surgery.
Pulmonary arterial hypertension (PAH) is a severe, progressive disease leading to right ventricular failure and finally death. Lung transplantation is recommended for PAH patients who do not respond to targeted drug combination therapy or World Health Organization functional class (WHO FC) Ⅲ or Ⅳ. However, only 3% of PAH patients can recieve the lung transplantation. A novel implantable interatrial shunt device (ISD) can create a relatively fixed right-to-left shunt established by balloon atrial septostomy (BAS). The device may decompress the right sided chambers, facilitate left heart filling, improve organ perfusion and reduce the likelihood of syncope, acute pulmonary hypertensive crisis and death. The systemic oxygen transport improves despite hypoxemia. Implantation is simple, feasible and safe, and the X-ray time and operation time are short. There is no severe complication or thrombosis during the mid-term follow-up of the clinical studies and the device remained patent. The syncope symptoms, six-minute walk distance, cardiac index and systemic oxygen transport improve significantly in the patients. ISD may be currently the last alternative treatment to improve symptoms and prolong survival in currently drug-resistant patients with severe PAH.
Objective To investigate the risk factors associated with the formation of parastomal hernia after Miles operation, and to provide scientific evidence for the prevention of parastomal hernia. Methods The clinical data of 218 patients with rectal cancer who undergoing Miles operation in the Affiliated Hospital of Xuzhou Medical University between May 2011 and May 2015 were analyzed retrospectively. Fifteen possible factors affecting the occurrence of parastomal hernia were selected. The fifteen related factors were analyzed by single factor analysis and two elements logistic regression analysis. Results A total of 55 patients with parostomy hernia occurred in 218 patients during follow-up period, and the incidence of parastomal hernia was 25.23%. Univariate analysis showed that age, thickness of subcutaneous fat in abdomen, BMI, stoma pathway, and hypertension were related to the formation of parastomal hernia after Miles operation (P<0.05). Further two elements logistic regression analysis showed that, advanced age, thickness of subcutaneous fat in abdomen, BMI>25 kg/m2, and transperitoneal were independent risk factors for the formation of parastomal hernia after Miles operation (P<0.05). Conclusion For patients with risk factors, it is very important to choose optimum stoma pathway during Miles operation to avoid the occurrence of formation of parastomal hernia after Miles operation.
ObjectiveTo explore the causes of colon-anal anastomotic stenosis in patients with low rectal cancer after prophylactic ileostomy under complete laparoscopy. MethodsA total of 194 patients with low rectal cancer who received complete laparoscopic radical resection of rectal cancer combined with preventive ileostomy in our hospital from January 2020 to December 2020 were selected as the study objects, and were divided into non-stenosis group (n=136) and stenosis group (n=58) according to postoperative colon-anal anastomosis stenosis. The clinical data of the two groups were compared. Univariate and multivariate logistic regression were used to analyze the factors affecting postoperative colon-anal anastomotic stenosis, and stepwise regression was used to evaluate the importance of each factor. The risk prediction model of postoperative colon-anal anastomotic stenosis was constructed and evaluated. ResultsIn the stenosis group, the proportion of males, tumor diameter ＞3 cm, NRS2002 score >3 points, manual anastomosis, left colic artery not preserved, anastomotic leakage, pelvic infection and patients undergoing neoadjuvant radiotherapy and neoadjuvant chemotherapy were higher than those in the non-stenosis group (P<0.05). The results of univariate logistic analysis showed that female and preserving the left colonic artery were the protective factors for postoperative colon-anal anastomotic stenosis (P<0.05), and the tumor diameter >3 cm, NRS2002 score >3 points, manual anastomosis, anastomotic leakage, pelvic infection, neoadjuvant radiotherapy and neoadjuvant chemotherapy were the risk factors for postoperative colon-anal anastomotic stenosis (P<0.05). Multivariate logistic regression analysis showed that gender, tumor diameter, NRS 2002 score, anastomotic mode, anastomotic leakage, and pelvic infection were independent influencing factors for postoperative colon-anal anastomotic stenosis (P<0.05). Stepwise regression analysis showed that the top three factors affecting postoperative colon-anal anastomotic stenosis were NRS 2002 score, gender and anastomotic leakage. Multivariate Cox risk proportional model analysis showed that the multivariate model composed of NRS 2002 score, gender and anastomotic leakage had a good consistency in the risk assessment of postoperative colon-anal anastomotic stenosis. Based on this, a risk prediction model for postoperative colon-anal anastomotic stenosis was constructed. The results of strong influence point analysis show that there are no data points in the modeling data that have a strong influence on the model parameter estimation (Cook distance <1). Receiver operating characteristic curve results showed that the model had good differentiation ability, the area under curve was 0.917, 95%CI was (0.891, 0.942). The calibration curve was approximately a diagonal line, showing that the model has good predictive power (Brier value was 0.097). The results of the clinical decision curve showed that better clinical benefits can be obtained by using the predictive model to identify the corresponding risk population and implement clinical intervention. ConclusionThe prediction model based on NRS 2002 score, gender and anastomotic fistula can effectively evaluate the risk of colon-anal anastomotic stenosis after preventive ileostomy in patients with low rectal cancer under complete laparoscopy.
ObjectiveTo investigate the effects of health education pathway intervention on self-care agency and health lifestyle promotion in colostomy patients. MethodsEighty-eight rectal cancer patients who had undergone colostomy were randomly divided into control group and intervention group (with 44 patients in each) between March 2012 and September 2013. The control group received conventional nursing only, while the intervention group were given health education pathway intervention besides conventional nursing. The self-care agency and health lifestyle promotion in the two groups under pre-colostomy state, one week after colostomy and two weeks after colostomy were surveyed and compared based on the exercise of self-care agency scale and the health promotion lifestyle profile. ResultsAfter health education pathway intervention, the scores of self-care agency and health lifestyle promotion in the intervention group were significantly higher than those in the control group (P<0.05), and the hospitalization expenditure was also obviously lower. Furthermore, the satisfaction degree on nursing service was significantly higher than that of the control group (P<0.05). ConclusionThe health education pathway intervention can greatly improve self-care agency and quality of life in rectal cancer patients who have undergone colostomy.
ObjectiveTo analyze the characteristics of colorectal cancer surgery in the current version of Database from Colorectal Cancer (DACCA).MethodsThe DACCA version selected for this data analysis was the updated version on April 16th, 2020. The data items included timing of operation, types of operative procedure, radical resection level of operation, patient’s wish of anus-reserving, types of stomy, date of stoma closure, surgical approaches, extended resection, and type of intersphincteric resection (ISR). The data item interval of stoma closure was added, and the selected data items were statistically analyzed.ResultsThe total number of medical records (data rows) that met the criteria was 11 757, including 2 729 valid data on the timing of operation (23.2%), 11 389 valid data on the types of operative procedure (96.9%), 4 255 valid data on the radical resection level of operation (36.2%), 3 803 valid data on patient’s wish of anus-reserving (32.3%), 4 377 valid data on types of stomy (37.2%), 989 valid data on date of stoma closure (8.4%), 4 418 valid data on surgical approaches (37.6%), 3 941 valid data on extended resection (33.5%), and 1 156 valid data on type of ISR (9.8%). In the timing of operation, the most cases were performed immediately after discovery or neoadjuvant completion (915, 33.5%). In types of operative procedure, ultra low anterior resection (ULAR), right hemicolectomy (RHC), and low anterior resection (LAR) were the most, including 1 986 (17.4%), 1 412 (12.4%), and 1 041 (9.1%) lines. Respectively in the colon and rectal cancer surgery, the proportion of RHC (50.0%) and ULAR (26.0%) was the highest, with 172 (26.1%) and 815 (27.9%) extended resection. In ISR surgery the majority was ISR-2 (741, 64.1%). In radical resection level of operation, the number of R0 was the largest with 2 575 (60.5%) lines. In patient’s wish of anus-reserving, positive and rational were the most with 1 811 (47.6%) and 1 440 (37.9%) lines, respectively. And in types of stomy, there were 2 628 lines (60.0%) without stoma and 1 749 cases (40.0%) with stoma, among which the most lines were right lower ileum stoma (612, 35.0%). The minimum value, maximum value, and median value of interval of stoma closure were 0 d, 2 678 d and 112 d. The linear regression prediction of date of stoma closure by year was \begin{document}${\hat {y}} $\end{document}=9.234 3x+22.394 (R2=0.2928, P=0.07). In the surgical approaches, the majority was standard with 3 182 (72.0%) lines.ConclusionsIn the DACCA, rectal cancer surgery is still the majority, and ULAR is the most type. The application of extended resection in both colon and rectal cancer has important significance. The data related to stoma are diversified and need to be further studied.
ObjectiveThis study aimed to discuss the risk factors associated with the delay reversal ileostomy following sphincter-preserving surgery for rectal cancer.MethodsClinical data were collected retrospectively on 130 consecutive patients undergoing defunctioning ileostomy following sphincter-preserving surgery for rectal cancer, between January 2014 and December 2014 in the Sixth Affiliated Hospital of Sun Yat-sen University. According to the reversal time of ileostomy, the patients were divided into two groups, including the delay reversal ileostomy group (≥120 d, n=72) and the normal ileostomy group (<120 d, n=58).ResultsOne hundred and thirty patients were studied (median time to reversal 132 d, range 39–692 d). Logistic regression model showed that adjuvant chemotherapy (OR=14.106, P=0.002), distance of tumor from the anal verge (OR=0.019, P=0.002), and anastomotic leakage (OR=32.440, P=0.001) were significant independent risk factors for delayed reversal. Time to reversal was significantly longer in those patients who had adjuvant chemotherapy, anastomotic leakage, and short distance of tumor from the anal verge.ConclusionAdjuvant chemotherapy, short distance of tumor from the anal verge, and anastomotic leakage are the independent risk factors for delay reversal ileostomy following sphincter-preserving surgery for rectal cancer.
