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.
Objective To summarize the surgical technique and the effectiveness of CK Parastomal patch in laparoscopic repair of parastomal hernia. Methods The cl inical data were retrospectively analysed from 24 patients who received laparoscopic repair of parastomal hernia using CK Parastomal patch between June 2006 and March 2010. There were 15 males and 9 females with a median age of 55 years (range, 47-80 years). Among them, 19 patients were with colon parastomalhernia in the left lower quadrant and 5 patients with ileum parastomal hernia in the right lower quadrant. The parastomal hernia duration was 1 to 4 years (mean, 2.4 years). The maximal diameter of the hernia ring was 3 to 7 cm (mean, 5.2 cm). All patients did not receive hernia repair. Results Laparoscopic repair of parastomal hernia was successfully performed in 18 cases, and open repair was used in 6 cases because of extensive adhesion. The average operating time was 121 minutes (range, 78 to 178 minutes). All wounds healed by first intention. Wound seroma occurred in 8 cases at 3 to 7 days after operation and disappeared by aspiration. Eleven patients complained of pain in the operative area within 1 month after operation and it disappeared without intervention. All patients were followed up 6 to 39 months (mean, 27 months). One recurrence occurred at 3 months after operation, and no recurrence occurred in the other patients. Conclusion Laparoscopic repair of parastomal hernia using CK Parastomal patch is a safe and feasible procedure with a satisfactory short-term effectiveness, but the long-term effectiveness should be further observed.
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.
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 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.
ObjectiveTo compare the clinical effects of enteral nutrition via stoma of jejunum or nasal-jejunum tube after Whipple procedure.
MethodsEighty-seven patients performed Whipple procedure were divided into nasaljejunum tube group(n=47)and stoma of jejunum group(n=40)according to the different enteral nutrition methods. The adverse reactions such as vomiting, abdominal distension, pharyngeal pain, and hypostatic pneumonia, anastomotic leakage, hospital stay, hospitalization expenses, and serum glucose and electrolyte(CL-, Na+, K+)on day 1, 3, 5 after operation were compared between two groups.
ResultsCompared with the nasal-jejunum tube group, the rates of adverse reactions and hypostatic pneumonia were more lower(P < 0.05), the hospitalization expense was more less (P < 0.05) in the nasal-jejunum tube group. The rate of anastomotic leakage and hospital stay had no significant differences between the nasal-jejunum tube group and stoma of jejunum group(P > 0.05). The differences of serum glucose and electrolyte(CL-, Na+, K+)on day 1, 3, 5 after operation were not statistically significant between two groups(P > 0.05).
ConclusionsEnteral nutrition via the stoma of jejunum after Whipple procedure has some better clinical effects in reducing adverse reactions such as vomiting, abdominal distension, pharyngeal pain, hypostatic pneumonia. The hospitalization expenses are decreased. There are no obvious effects on the hospital stay, blood glucose and electrolyte concentration on day 1, 3, 5 after operation.
