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.
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 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.
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.
ObjectiveTo contrastive the clinical results of intraperitoneal sigmoid colostomy and extraperitoneal sigmoid colostomy in abdominal perineal resection. MethodsThe clinical data of 172 patients who underwent abdominal perineal resection from March 2010 to March 2014 were retrospectively analyzed.Sixty cases were performed the intraperitoneal sigmoid colostomy (intraperitoneal group), seventy-six cases were performed the extraperitoneal sigmoid colostomy (extraperitoneal group), and thirty-six cases were performed the functional exercise after extraperitoneal sigmoid colostomy (functional exercise group). The operation situation, postoperative complications, and colostomy function of three groups of patients were compared. Results①Operation situation: The colostomy location selection, operative time, intraoperative blood loss, and postoperative hospital stay of the three groups had no statistically significant differences (P > 0.05). The postoperative first exhaust and defecate time of the intraperitoneal group and the functional exercise group were obviously earlier than the extraperitoneal group, the difference had statistical significance (P < 0.05).②The postoperative complications: The postoperative complications rates of the extraperitoneal group and functional exercise group were lower than the intraperitoneal group, had statistically significant difference (P < 0.05), the functional exercise group was lower than the extraperitoneal group, the difference had statistical significance (P < 0.05).③The colostomy function:The patient' proportion that > 30 s of appeared time of defecation signals in the extraperitoneal group was significantly higher than the intraperitoneal group, and the functional exercise group was higher than that in the extraperitoneal group, the difference were statistically significant (P < 0.05). The patient' proportion that > 2 min of autonomous control of defecation to discharge feces time after the bowel signal appears in the extraperitoneal group was significantly higher than the intraperitoneal group, and the functional exercise group was higher than that in the extraperitoneal group, the difference were statistically significant (P < 0.05). Conciusions The intraperitoneal sigmoid colostomy has less colostomy related complications than extraperitoneal sigmoid colostomy in abdominal perineal resection. The control, and defecate ability are better. Postoperative function exercise can further reduce the colostomy complications and improve the function of colostomy.
