The secondary anastomotic stenosis is often occured from the repair and reconstructive operation of the injured bile duct. It is difficult to treat and the outcome is serious. In order to prevent this complication, the fibrin glue instead of traditional suturing technique combined with inner support was used. Fifty-four hybrid dogs were divided into 3 groups. Group A received Roux-en-y choledochojejunostomy with fibrin glue; group B received Roux-en-y choledochojejunostomy, with a fibrin glue combined support left permanently in the bile duct and group C received Roux-en-y choledocholejejunostomy with fibrin glue combined a support left temporarily in the bile duct. The amount of collagen in the scar was measured at 3/4, 3, 6, 9, 12 months respectively after operation. The results showed: 1. the mature period of scar was shortened from 12 months to 9 months when fibrin glue instead of suture was used in choledochojejunostomy; 2. the mature period of scar was further shortened from 9 months to 6 months when fibrin glue combined with inner support instead of fibrin glue was used in choledochojejunostomy. The conclusions were as follows: 1. fibrin glue could facilitate the healing of wound by inhibiting the formation of scar and accelerrate the maturation of scar; 2. when the inner support was used with fibrin glue in the operation, the mature period of scar could be further shortened; 3. the mechanism of action of the fibrin glue included minimizing the injury, avoiding foreign-body reaction, modifying organization of hematoma, preventing formation of biliary fistular and enhancing intergration and cross-linkage of collagen.
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 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.
The antireflux spur-valvewas originally designed for the Roux-Y cholenterostomy. It is made by plication of the two upper limbs of the "Y" after the removal of the seromusculature from the biliary limb, so that the conjoined wall-in-between will he compassed deviating to the biliary, side to form a spur value. It could successfully stop the reflux due to normal peristalsis or intestinal distension. This value was primarily used in choledochal cyst and biliary atresia for more than 100 cases, and also applielied to many other operations for perventing reflux, including: gastroesophageal refluk-Nissen fundoplication, colon replacement of esophagus, side to side shert-circuit of intestinal obstruction, and Kock scontinent ileoslomny. The detailed procedures were described.
ObjectiveTo summarize the application and the complications of pancreaticogastrostomy (PG) after pancreaticoduodenectomy(PD). MethodThe domestic and international publications involving the theory, methods, and clinical application of PG were retrieved and reviewed. ResultsPG was gradually concerned on the choice of the method of the digestive tract reconstruction after PD, in view of its advantages in theory and operation. The literatures about PG were increased in recent years. But the discussion of decreasing complications of PG after PD had yet to be unified. ConclusionsPG is one of the important operations of digestive tract reconstruction after PD. The factors of operator and patient should be comprehensively considered in the choice of PG.
Objective To investigate the influence of preoperative enteral nutrition with dietary fiber on the nutritional status of patients with colon colostomy diaplasis, and discuss its safety. Methods Forty preoperative colon colostomy diaplasis patients from West China Hospital treated between September 2013 and June 2014 were randomly assigned into trial group and control group with 20 in each. The baseline of the two groups was the same (all P > 0.05). The trial group was given enteral nutrition with dietary fiber before operation for seven days, while control group was given homogenate diet with equal quantity of energy and nitrogen content for the same period of time. All patients were being tested for nutritional indexes on the day of admission and on the fifth day after surgery. Meanwhile, other indexes such as the first time of flatus and defecation, abdominal distension, bellyache, and other adverse reactions were recorded too. Results There was no statistical difference in nutritional indexes on the day of admission and on the fifth day after surgery between two groups (P > 0.05). Patients with dietary fiber had significantly higher incidence of abdominal distension than the control subjects (P < 0.05), but other adverse reactions had no statistical differences between the two groups (P > 0.05). No anastomotic leakage occurred in both the two groups. Patients with dietary fiber had significantly earlier time of flatus than the control group (P < 0.05). Patients with dietary fiber had significantly lower incidence of diarrhea than the control subjects (P < 0.05). Conclusions The study suggests that it is safe and feasible to use enteral nutrition with dietary fiber for preoperative colon colostomy diaplasis patients. Using dietary fiber is helpful for intestinal function recovery and reduction of the occurrence of adverse reactions after surgery.
Objective To investigate the new method of pancreaticoenterostomy and decrease the probability of complications like pancreatic fistula etc. Methods By using the absorbable bandage and ear-brain glue, modified sutureless pancreaticoenteromy was made in 10 swines. Experimental data includes： routine analysis of blood, levels of amylase in blood and abdominal drainage and lipase in blood and abdominal drainage. The tissues in anastomosis were taken for pathology examination in 1 month after operation. Results The average operative time was （35±10） min.Nine of ten animals had no pancreatic fistula and survived. The levels of amylase and lipase in abdominal drainage were both normal. One swine had a evident abdominal distensile on 2 days after operation, the level of amylase was 10 000u/L,then died on 10 days after operation. Pancreatic fistula and infection were found because of the loss of stent in pancreatic duct. Conclusions Comparison with traditional operation, the modified sutureless pancreaticoenteromy can also control the probability of pancreatic fistula. And this method can be hoped to be one of the routine operations of pancreaticoenterostomy because of its simplicity and practicality.
Objective To assess the effectiveness and safety of hand-suture vs. stapling anastomosis in esophagogastrostomy. Methods The following databases such as CBM (1978 to February 2012), VIP (1989 to February 2012), CNKI (1994 to February 2012), WanFang Data (1980 to February 2012), The Cochrane Library, PubMed (1966 to February 2012), EMbase (1974 to February 2012), and relevant webs of clinical trials were searched to collect the randomized controlled trials (RCTs) and quasi-RCTs about hand-suture vs. stapling anastomosis in the incidence of anastomotic leakage following esophagogastrostomy. Moreover, relevant references and grey literature were retrieved on web engines including Google Scholar and Medical Martix, and the Chinese periodicals e.g. Chinese Journal of Oncology were also handsearched. According to the inclusion and exclusion criteria, the literature, was screened, the data were extracted, and the quality of the included studies was assessed. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 9 RCTs involving 2 202 patients were included. The result of meta-analysis was as follows: the incidence of anastomotic leakage in the stapling anastomosis group was lower than that in the hand-suture anastomosis group (OR=0.43, 95%CI 0.26 to 0.71, Plt;0.01). Conclusion Stapling anastomosis is superior to hand-suture anastomosis in reducing the incidence of anastomotic leakage following esophagogastrostomy. For the limited quality and quantity of the included studies, this conclusion has to be further proved by more high-quality studies.
Objective To explore primary surgical treatment experience of typeⅣ hilar cholangiocarcinoma. Methods From April 2008 to April 2011，20 patients with type Ⅳ hilar cholangiocarcinoma were enrolled into the same surgical group in Department of Hepatobiliary and Pancreatic Surgery of West China Hospital of Sichuan University.The intra- and post-operative results were analyzed.Results The total resection rate was 75%，which was consisted of 10 cases of radical excision and 5 cases of non-radical excision.Seven patients received left hepatic trisegmentectomy and caudate lobe resection including anterior and posterior right hepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy.Six patients received enlarged left hepatic trisegmentectomy and caudate lobe resection including left intrahepatic and extrahepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy. Two patients received quadrate lobe resection including two cholangioenterostomies after anterior and posterior right hepatic duct reconstruction，and left intrahepatic and extrahepatic duct reconstruction.After percutaneous transhepatic cholangial drainage （PTCD） and portal vein embolization （PVE），two patients with total bilirubins ＞400 mmol/L received radical excision and non-radical excision，respectively.Three patients only received PTCD during operation due to wide liver and distant metastasis，and two patients received T tube drainage during operation and postoperative PTCD due to left and right portal vein involvement. All 15 patients who received lesion resection survived more than one year， whereas another five patients whose lesions can not been resec ted only survived from 3 to 6 months with the mean of 4.2 months.No death occurred during the perioperative period. Conclusions For patients with type Ⅳ hilar cholangiocarcinoma， preoperative evaluation and tumor resection shall conducted so as to relieve obstruction of biliary tract，otherwise PTCD and PVE prior to the final lesion resection shall be performed.
