ObjectiveTo evaluate whether laparoscopic repair for perforated peptic ulcer o ers elderly patients an improved outcome compared with conventional open surgery. MethodsFrom May 2008 to December 2013, clinical data of 163 elderly patients ( ≥ 60 years) who underwent laparoscopic or open repair of perforated peptic ulcer disease were analyzed retrospectively in our hospital. Ninety-one patients received laparoscopic repair and 72 received conventional open repair. The primary end points that were evaluated were total operative time, searching time, nasogastric tube utilization, intravenous fluid requirement, total time of abdominal drainage and urinary catheter usage, time taken to return to normal gastrointestinal motility, percentage of intravenous/intramuscular opiate use, off-bed time, and total in-patient hospital stay. The second end points were morbidity. ResultsThere was a significant diTherence in total operative time in patients who had undergone laparoscopic repair and open repair [(67.9±3.6) minutes vs. (97.8±5.2) minutes]. There was a significant decrease in the time that the nasogastric tube (2.1 days vs. 3.1 days), urinary catheter (2.3 days vs. 3.7 days) and abdominal drain (2.2 days vs. 3.8 days) were required during the postoperative period. Patients who had undergone laparoscopic repair also required less intravenous fluids (2.4 days vs. 4.1 days) and returned to normal gastrointestinal motility [(32.1±1.5) hours vs. (58.4±4.8) hours] and off-bed time significantly earlier than those who had undergone open repair (2.1 days vs. 3.5 days). There was significantly less requirement for intravenous/intramuscular opiate analgesia in patients who had undergone laparoscopic repair (4.7% vs. 45.6%). In addition, patients who had undergone laparoscopic repair required a shorter in-patient hospital stay (4.1 days vs. 5.3 days). Moreover, morbidity of laparoscopic repair was much lower than open repair (3.3% vs. 16.7%). ConclusionLaparoscopic repair is a viable and safe surgical option for elderly patients with perforated peptic ulcer disease and should be considered for all patients.
ObjectiveTo analyze the common reasons of anastomotic leakage following sphincter preservation for rectal cancer, and to explore the better prevention and treatment strategies. MethodThe related literatures of the definition, common causes, and prevention and treatment status of anastomotic leakage were reviewed. ResultsCurrently rectal cancer was one of common malignant tumors, including about 2/3 low rectal cancer.Recently, sphincter preserving surgery had become the preferred surgical procedure.However, the incidence of anastomotic leakage keeping in higher was still the most serious and common complications.Through improving the general condition of the patients, improving surgical techniques, and standardized treatment could effectively reduce the incidence of anastomotic leakage. ConclusionReasonable preoperative assessment for the basic situation of patients with rectal cancer, standardized and individualized treatments, contribute to reduce incidence of anastomotic leakage and improve clinical outcomes in patients with low rectal cancer.
ObjectiveTo study the clinical application of enteral microecopharmaceutics immunonutrition in the peroperation of colorectal cancer. MethodsLiteratures about enteral microecopharmaceutics immunonutrition published in China and abroad were collected and reviewed. ResultsEarly clinical application of enteral microecopharmaceutics immunonutrition in the perioperation can greatly improve the nutritional status of patients with colorectal cancer, increase the patients' immune function, reconstruct the intestinal flora, and reduce the incidence of complications. ConclusionsThe clinical application of enteral microecopharmaceutics immunonutrition in the perioperation of colorectal cancer can obviously improve patients' nutritional status and immune function, reduce the stress response, and improve its prognosis, but the use of best dose still need further study.
Objectives To analyze risk factors associated with conversion to open surgery of laparoscopic repair for perforated peptic ulcer. Methods From January 2009 to December 2014, 235 patients underwent laparoscopic repair for perforated peptic ulcer in the Chengdu 5th Hospital, were enrolled in this study. These patients were divided into laparoscopic repair group (n=207) and conversion to open surgery group (n=28). The characteristics, clinical outcomes, and prognosis factors were compared between these two groups. The receiver operating characteristic (ROC) curve was used to determine the critical cutoff value for diameter and duration of perforation for predicting conversion to open surgery. Results There were no significant differences of the age, gender, body mass index, comorbidity, history of ulcer, smoking history, history of nonsteroidal antiinflammatory drugs or steroids use, history of alcohol use, American Society of Anesthesiologists classification on admission, white blood cell count on admission, C reaction protein on admission, surgeons, suture method, and location of perforation between these two groups (P>0.05). The patients in the conversion to open surgery group had a higher procalcitonin (PCT) level on admission (P=0.040), longer duration of peroration (P<0.001), larger diameter of peroration (P<0.001), longer hospital stay (P=0.002), higher proportion of patients with Clavien-Dindo classification Ⅰ and Ⅱ (P<0.001), longer gastrointestinal function recovery time (P=0.003), longer analgesics use time (P<0.001), and longer off-bed time (P=0.001) as compared with the laparoscopic repair group. The results of logistic regression analysis showed that the peroration duration on admission〔OR: 2.104, 95%CI (1.124, 3.012),P=0.020〕and peroration diameter on admission〔OR: 2.475, 95%CI (1.341, 6.396),P=0.013〕were two predictors of conversion to open surgery. For the diameter of perforation, 8.0 mm was the critical cutoff value for predicting conversion to open surgery by ROC curve analysis, the sensitivity was 76%, the specificity was 93%, and the area under the curve (AUC) was 0.912. For the duration of perforation, 14 h was the critical cutoff value to predict conversion to open surgery, the sensitivity was 86%, the specificity was 71%, and theAUC was 0.909. Conclusions The preliminary results in this study show that diameter of perforation of 8 mm and duration of perforation of 14 h are two reliable risk factors associated with conversion to open surgery for perforated peptic ulcer. Also, PCT level would mightbe considered as a helpful risk factor for it.
Objective To research the effect of ω-3 polyunsaturated fatty acid (PUFA) on inflammatory response and nutritional condition after operation for patients with gastrointestinal malignancies. Methods Forty patients with gastrointestinal malignancies were included in this study from February 1st, 2009 to June 1st, 2009. Forty cases were randomly allocated to experimental group (20 cases) and control group (20 cases). Parenteral nutrition was conducted in continuous 7 days after operation. Comparing with control group, a dose of 10 g of ω-3 PUFA was given to experimental group every day in 7 days after operation in addition. Blood samples were gained before operation, the 2nd and 8th day after operation respectively to measure relative indexes about inflammatory response (WBC, neutrophilic granulocyte and C-reaction protein) and nutrition (total protein, albumin, prealbumin, siderophilin and lymphocyte). Reduction of body mass was also recorded. Results The baseline between experimental group and control group was comparable (Pgt;0.05). The levels of indexes about inflammatory response (WBC, neutrophilic granulocytem and C-reaction protein) and nutrition (total protein, albumin, prealbumin, siderophilin and lymphocyte) between experimental and control group did not reach statistically significant difference in the 2nd day after operation (Pgt;0.05). The levels of neutrophilic granulocyte and C-reaction protein in experimental group were lower than those of control group, and the level of lymphocyte in experimental group was higher than that of control group in the 8th day after operation, and all of them reached statistical significance (Plt;0.05). There was no statistical different in reduction of body mass between experimentalgroupandcontrolgroup.Conclusion ω-3 PUFA can depress the excessively inflammatory reaction and improve the nutritional condition of patients with gastrointestinal malignancies after operation.
T lymphocyte acid α-naphthl acetate esterase (Tc-ANAE) activity was measured in 23 pathologically proved gastric cancer patients before and after surgical intervention. The result showed that interventional treatment obviously decreased the Tc-ANAE activity in patients with gastric cancer (Ｐ＜0.01), especially decreased the immune function in late stage cases (stage Ⅳ) (Ｐ＜0.01), the more advanced the cancer was, the more impaired the immune function was. Interventional treatment had no influence on immune function in earlier stages (Ｐ＞0.05).
Objective To explore the postoperative influence of intra-abdominal implantation of sustained-releasing 5fluorouracil on the hepato-renal function, immune function, nutritional state and complications in patients with gastric and colorectal cancer. Methods Sixty-five patients with gastric or colorectal cancer were included into this study from January to June 2009. The patients (35 cases of gastric cancer, 18 cases of colon cancer and 12 cases of rectal cancer) were randomly divided into experimental group (n=25) and control group (n=40). In experimental group, 400 mg sustained-releasing 5-fluorouracil was used. Blood samples were gained before operation, the second day and the seventh day after operation to examine the indexes of hepato-renal function, immune function and nutritional state. Complications， venting time and length of stay after operation were also recorded. Results There was no statistical significance for distribution of tumor stages and patients’ gender between experimental group and control group (Pgt;0.05). Preoperative indexes of hepato-renal function, immune function and nutritional state were also not reached statistical significance between two groups (Pgt;0.05). Compared with control group, the indexes of total protein and transferrin were decreased and urea nitrogen and IgM were increased in the second day after operation in experimental group (Plt;0.05). The number of lymphocyte was increased, while CD4, Alb, total protein and IgA were decreased in the seventh day after operation in experimental group, respectively. The time of passage of gas of experimental group was longer than that of control group (Plt;0.05).Conclusion Intra-abdominal implantation of sustained-releasing 5-fluorouracil is safe and feasible, which does not increase the complications and the time of length stay after operation. However, there is a little influence on immune function and gastrointestinal function after operation for intra-abdominal implantation of sustained-releasing 5-fluorouracil.
