OBJECTIVE: To investigate the effect of vasostomy on apoptosis in the male rat spermatogenic cells after vasoligation. METHODS: Model of vasoligation and vasostomy in male rat was established, and then terminal deoxynucleotidyl transferase-mediated dUTP nick labelling technique to detect the apoptosis of spermatogenic cells at 4, 8, 12, 16 weeks after vasostomy. RESULTS: The number of apoptotic cells in vasostomy group was significantly lower than that of vasoligation group since 8 weeks after vasostomy(P lt; 0.05). The number of apoptotic cells in 8 and 12 weeks after vasostomy were significantly higher than that in prevasoligation(P lt; 0.05). 16 weeks after vasostomy, the number of apoptotic cells restored to the level same as that in prevasoligation stage. CONCLUSION: Vasostomy can reverse the apoptosis of spermatogenic cells due to vasoligation.

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.
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 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 evaluate the linkage between the proxmal as well as long term outcome and choice of therapeutical modality for benign hilar stricture of bile duct prospectively. Methods 25 patients have been catergorized into 4 groups according to different pathogen and the proxmal as well as long term outcome after pathogen based management have been studied prospectively. Results The hepatic portal cholangio-jejunostomy applied for iatrogenic hilar stricture of bile duct has been proved to be effective and the incidence of refulux cholangitis is only 10%(1/10). Hepatic hilar plasty procedures keep the physiological entitity of bile duct and the vital, sufficient autologous repair materials as well as reliable operation design are needed. Resection of atrophic right liver lobe bearing hepatolithiasis combined hepatic hilar plasty has reached both elimination of liver focus and maintaining the physiological entitity of bile duct. The ballon dilation for mild ring-like hilar stricture of bile duct is valide but not for hilar tubular stricture of secondary sclerosing cholangitis.Conclusion The strategy of individualized management (pathogen based management) for benign hilar stricture of bile duct has proved to be reliable and effective.
ObjectiveTo explore the optimal surgical timing of sequential laparoscopic cholecystectomy (LC) following percutaneous cholecystostomy (PC) in the patients with acute cholecystitis, so as to provide a clinical reference. MethodsThe patients who underwent PC and then sequential LC in the Fifth Affiliated Hospital of Xinjiang Medical University from March 2021 to July 2023 were selected based on the inclusion and exclusion criteria, who were categorized into 3 groups: the short interval group (3–4 weeks), the intermediate interval group (5–8 weeks), and the long interval group (>8 weeks) based on the time interval between the PC and LC. The gallbladder wall thickness before LC, operative time, intraoperative blood loss, postoperative hospitalization time, total hospitalization time, time and cases of drainage tube placement, admission to intensive care unit, conversion to open surgery, occurrence of complications, and total hospitalization costs were compared among the 3 groups. ResultsA total of 99 patients were enrolled, including 25 in the short interval group, 41 in the intermediate interval group, and 33 in the long interval group. The data of patients among the 3 groups including demographic characteristics, blood routine, C-reactive protein, interleukin-6, fibrinogen, international standardized ratio, liver function indicators, and comorbidities had no statistical differences (P>0.05). The gallbladder wall thickness before LC and the operative time, intraoperative blood loss, postoperative hospitalization time, total hospitalization time, time and cases of drainage tube placement, admission to intensive care unit, conversion to open surgery, occurrence of complications, and total hospitalization costs during and after LC had statistical differences among the 3 groups (P<0.05). These indicators of the intermediate interval group were better than those of the other two groups by the multiple comparisons (P<0.05), but which had no statistical differences except total hospitalization costs (P=0.019) between the short interval group and the long interval group (P>0.05). ConclusionAccording to the results of this study, the optimal surgical timing of sequential LC following PC is 5–8 weeks, however, which needs to be further validated by large sample size and multicenter data.
ObjectiveTo compare the effectiveness of antecolic duodenojejunostomy (ADJ) and retrocolic duodenojejunostomy (RDJ) after pylorus-preserving pancreaticoduodenectomy (PPPD). MethodsRandomized controlled trials (RCTs) of ADJ versus RDJ after PPPD were searched in Cochrane Library, PubMed database, Embase database, Web of Science, Chinese biomedicine database, CNKI database, VIP database, and Wanfang database from inception to April 2014, as well as Google. After quality assessment of RCTs according to the Cochrane Handbook for Systematic Reviews of Interventions Version, Meta analysis was performed by RevMan 5.1 software. ResultsFour RCTs of 462 patients in total were included in this Meta-analysis. The results of Meta-analysis showed that, there were no significant differences in the operation time (MD=14.02, 95% CI:-41.42-69.46, P=0.62), incidence of postoperative complications (RR=1.09, 95% CI:0.81-1.48, P=0.56), incidence of delayed gastric emptying (RR=0.63, 95% CI:0.31-1.28, P=0.20), incidence of pancreatic fistula (RR=1.13, 95% CI:0.72-1.75, P=0.60), incidence of abdominal abscess (RR=0.92, 95% CI:0.54-1.58, P=0.77), and mortality (RR=0.61, 95% CI:0.24-1.60, P=0.32) between ADJ group and RDJ group. ConclusionsThe effectiveness of ADJ is similar with RDJ after PPPD, so the reconstruction way after PPPD can be routed according to the surgeon's preference.

Tracheostomy is conducive to airway management and offline extubation in patients assisted by long-term breathing, and promotes patient recovery and discharge through multidisciplinary collaborative rehabilitation nursing integrated case management.
Objective To evaluate the application effect of modified jejunostomy in thoracoscopic Ivor-Lewis esophagectomy. Methods A retrospective analysis of patients who underwent Ivor-Lewis esophagectomy for middle and lower esophageal cancer from 2017 to 2023 in our department was performed. The patients from 2017 to 2020 receiving "C+I" in the upper jejunum according to the "C+I" model, and fistula fixed with only two purse-string sutures and the abdominal wall were allocated into a group A. The patients from 2021 to 2023, on the basis of "C+I" suture, the jejunum and abdominal wall fixed with 3-0 absorbable thread for 1-2 needles at the proximal or distal end of the fistula 10-15 mm, and the upper jejunum and abdominal wall fixed into "curtain" were allocated into a group B. The operation time, jejunostomy time, postoperative pathological stage, and enteral nutrition-related complications such as the incidence of incomplete intestinal obstruction, closed loop intestinal obstruction and intestinal volvulus requiring secondary surgery, skin redness and swelling of intestinal fluid leakage, stoma tube blockage, and accidental extubation were compared between the two groups. Results All patients successfully completed Ivor-Lewis esophagectomy under thoracoscopy. There was no perioperative death. There were 118 patients in the group A, including 72 males and 46 females, with an average age of 64.58±6.30 years. There were 125 patients in the group B, including 76 males and 49 females, with an average age of 65.11±6.81 years. There was no statistical difference in operation time, jejunal fistula time, fistula blockage or accidental extubation rate between the two groups (P>0.05). There was a statistical difference in the incidence of incomplete intestinal obstruction (P=0.035), and closed loop intestinal obstruction requiring secondary surgery (P=0.017). There were 36 patients of eczema-like changes in the patients with severe intestinal leakage and redness in the group A, and 7 patients of intestinal leakage and redness in the group B (P<0.001). Conclusion The modified jejunostomy can significantly reduce the incomplete intestinal obstruction, closed loop intestinal obstruction and secondary operation rate after "C+I" jejunostomy, and significantly improve the leakage of intestinal fluid at the stoma and the injury of surrounding skin and soft tissue. Improvements in certain technologies reduce operational difficulties and is worthy of promotion and application in clinical practice.
