ObjectiveTo investigate the reason, prevention, and treatment measures of gastrointestinal unplanned reoperation. MethodsClinical data of 21 patients who carried out gastrointestinal unplanned reoperation for various reasons from Jun. 2012 to Jun. 2013 in our hospital were retrospectively analyzed. ResultsTwenty-one of 2 492 patients with gastrointestinal tract surgery carried out gastrointestinal unplanned reoperation, and the incidence of reoperation was 0.8%. The causes of reoperation were intra-abdominal hemorrhage in 10 cases, gastrointestinal fistula in 7 cases, inflammatory intestinal obstruction with peritonitis in 1 case, and incision dehiscence in 3 cases. After undergoing suture hemostasis, colostomy, anastomotic fistula repair, debridement, and suture,20 cases were cured or improved, and 1 case died. The median of hospitalization expense was 76 000 yuan(46 000-116 000 yuan), and the median of hospital stay was 25-day(16-49 days). ConclusionsGastrointestinal unplanned reoperation can cause more serious economic and emotional burden to patients, standardizing surgical procedure and enhancing perioperative monitoring can reduce the incidence of unplanned reoperation. In addition, grasp legitimately the indications of reoperation, implement timely, and effective reoperation can avoid further deterioration of the disease.
Objective To investigate the changes of gastrointestinal hormone and body composition in patients with gastric cancer after gastrectomy. Methods Thirty-eight patients with gastric cancer were divided into three groups: distal gastrectomy group, proximal gastrectomy group and total gastrectomy group and 9 volunteers as control group. The nutrition status and gastrointestinal function were evaluated by four times. The time of postoperative first anal exsufflation and defacation, hospital stay and complications were recorded, and the pre-meal and the post-meal level of gastrointestinal hormones 1 month after operation were detected. Results Compared with control group, the basic levels of somatostatin (SS), cholecystokinin (CCK) and motilin (MTL) of distal gastrectomy group, proximal gastrectomy group and total gastrectomy group significantly increased (Plt;0.01). The post-meal level of gastrointestinal hormones significantly increased as compared with the pre-meal level in each group (Plt;0.01). The CCK in proximal gastrectomy group was lower than that of distal gastrectomy group and total gastrectomy group (Plt;0.01). The postoperative body weight and body composition in each group decreased. One month after operation, patients of total gastrectomy group got the lowest body weight (Plt;0.01). The decreasing level of fat free mass (FFM) was listed by total gastrectomy group, proximal gastrectomy group and distal gastrectomy group. The edema index had significant difference in distal gastrectomy group, proximal gastrectomy group and total gastrectomy group (Plt;0.01), and total gastrectomy group was the most obvious. The postoperative passing flatus and defecation time and average hospital stay in total gastrectomy group were significantly prolonged (Plt;0.05). The gastrointestinal symptoms score among three groups was significantly different (Plt;0.05). Conclusion There are different changes of gastrointestinal hormone and body composition in patients with gastric cancer after different gastrectomy, the basic levels of SS, CCK and MTL of distal gastrectomy group, proximal gastrectomy group and total gastrectomy group are higher than those of control group. The CCK of proximal gastrectomy group is lower than that of distal gastrectomy group and total gastrectomy group. Patients received total gastrectomy lose much body weight and FFM and get higher edema index.
Objective To investigate the safety and efficiency of a blood glucose control method in diabetic patients with gastrointestinal neoplasm who were subjected to postoperative early enteral nutrition (EEN). Methods Thirty-seven diabetic patients with gastrointestinal neoplasm received enteral nutriment——Glucerna SR through nasojejunal tubes 24 hours after operation. The blood glucose level was safely controlled through injecting insulin intravenously and subcutaneously. Meanwhile, any change of blood and urine glucose level was monitored and the indexes representing the levels of nutrition, biochemistry and immunity were measured before the implementation of EN, 5 d and 8 d of EN after operation, respectively. Results All the patients were able to bear EEN and there was no severe complications occurred. Significant increase of serum levels of albumin, prealbumin and transferrin were observed after EEN support （P＜0.05）, as well as the serum levels of IgG， IgA and IgM （P＜0.01）. However, body weight， HGB and the serum levels of ALT and TBIL showed no significant changes （Pgt;0.05）. There were 81.1%（30/37） of patients whose blood glucose levels were controlled steadily within the range of (7.8±1.1) mmol/L. Conclusion Injecting insulin intravenously and subcutaneously after operation may be a safe and effective method to control blood glucose level. And the postoperative implementation of EEN can be considered as the first choice of nutrition support for diabetic patients with gastrointestinal neoplasm.
ObjectiveTo summarize the pathogenesis and epidemiology features of gastrointestinal stromal tumor(GIST), explore its diagnosis and therapy, and analyze its prognosis. MethodThe pertinent literatures about the pathogenesis, epidemiology features, diagnosis, therapy, and prognosis of GIST in recent years were reviewed. ResultsGIST was non-epithelial tumor which derived from interstitial cells of Cajal, was the most common mesenchymal tumor about accounting for 1%-3% in the digestive tract tumor. The median onset age of patients with GIST was 40-60 years. The gastric stromal tumor was about 60% in all the digestive tract tumor. The current consensus statement was that there was a relation between the pathogenesis of the GIST and proto-oncogene c-kit or platelet-derived growth factor receptor alpha(PDGFRα)gene mutation. But the mutations of PDGFRαand c-kit gene did not emerge at the same time in the same patient. The clinical manifestations of GIST were not specific, and the diagnosis mainly depended on endoscope and image technology, the correct diagnosis depended on pathological examination. The treatment of GIST was given priority of surgery and molecular targeted drug therapy, and the prognosis was closely related to risk assessment stratify of GIST. ConclusionsGISTs are mesenchymal tumors that has a potential of malignant transformation, the risk classification criteria for aggressive clinical course of primary GIST is an important indication for guiding the clinical therapy and prognostic evaluation. Further research would be needed in prevention, diagnosis, treatment, and relapse prevention of GIST.
Objective To observe the effect of fresh orange peel flavor inhalation on the improvement of gastrointestinal reactions such as nausea and vomiting in tumor patients during chemotherapy. Methods Ninety-one inpatients undergoing chemotherapy with PF and TP regimens between May 2012 and September 2013 were included in this study. The patients were randomly divided into orange group (n=45) and control group (n=46). Patients in the control group received conventional care, while those in the orange group were treated with fresh orange peel flavor inhalation during chemotherapy. We observed the effect of orange peel flavor inhalation on such gastrointestinal reactions as nausea and vomiting in tumor patients during chemotherapy. Results All the patients completed each cycle of chemotherapy. At the fifth day during chemotherapy, compared with the control group, the incidence rates of grade Ⅲ-Ⅳ gastrointestinal reactions (nausea and vomiting) in the orange group were significantly lower (P=0.023). At the fourth day, when gastrointestinal reactions were the most significant, the food intake of patients in the orange group was significantly higher than that in the control group (P=0.012). During chemotherapy, the addition rate of antiemetic drugs in the orange group was significantly lower than that in the control group (P=0.038). In the orange group, 80.0% of the patients had good self-feeling after orange peel flavor inhalation. Conclusions The study results have shown that fresh orange peel flavor inhalation can effectively improve the gastrointestinal reactions (such as nausea and vomiting), appetite, and degree of comfort in tumor patients during chemotherapy, and reduce the use of antiemetic drugs. This study is of great significance to guide the future research on how to reduce the discomfort of on-chemotherapy patients and provide more comfortable care.
Objective To review the relationship between histone modifications and gastrointestinal cancer. Methods Literatures on histone modifications and the relationship between histone modifications and gastrointestinal cancer were collected and reviewed. Results Histone modifications played an important role in the establishment of gene silencing during tumorgenesis. DNA methylation and histone modifications might interact with each other and form a complex network to establish and maintain gene silencing. Restoring gene function silenced by epigenetic changes in cancer had the potential of ‘normalizing’ cancer cells, which was named epigenetic therapy. Epigenetic therapy was very promising in prevention and treatment of gastrointestinal cancer, but many unsolved issues remain which need to be addressed in future studies. Conclusion Histone modifications are associated with the pathogenesis of gastrointestinal cancer. Restoring gene function silenced by epigenetic changes may have a great role in the prevention and treatment of gastrointestinal cancer.
【Abstract】ObjectiveTo study the diagnosis and the treatment of gastrointestinal stromal tumor (GIST). Methods In this retrospective study, tissue slices, including immunohistochemical examinations, of 48 patients with GIST from January 1999 to December 2004 were collected. All of their clinical symptoms, pathologic characters, and surgical treatment and other information were also analyzed. ResultsTwenty-seven males and 21 females with a mean age of 68 were included in this report. All patients received tumor resections. Tumors were located in the stomach in the 29 cases (60.4%), and 11 cases (22.9%) were in the small intestine. The main clinical manifestations were alimentary tract hemorrhage (52.1%) and abdominal mass (35.4%). Immunohistochemical examination showed the positive rate of CD117 was 83.3%(40/48), and CD34 was 77.1%(37/48). Conclusion GIST mostly occurs at stomach and small intestine in aged people with clinical manifestations of alimentary tract hemorrhage and abdominal mass. The diameter of the mass is an important clinical index to distinguish malignant and benign tumors. The diagnosis of GIST depends on the combination of pathological and immunohistochemistry examinations. Complete regional resection of the tumor may be the most effective treatment.
ObjectiveTo investigate the specific CT findings of high-risk gastrointestinal stromal tumors (GISTs). MethodsCT findings of 24 patients with high-risk GISTs from August 2009 to March 2014 proved by surgery and pathology were retrospectively reviewed. ResultsTwelve of the high-risk GISTs were from the stomach, 11 from the small intestine (5 from duodenum, 4 from jejunum, and 2 from ileum), and 1 from the rectum. The biggest transverse diameter of the tumor was between 2.5 and 15.0 cm, and 2 were less than 5 cm and 22 of them were over 5 cm. The tumors appeared as irregular in 20 cases, and with indefinite boundary in 21 cases. Twenty-four tumors showed different levels of necrosis and cystic change, 15 showed ulcer, 2 showed perforation with effusion and pneumatosis, and 3 showed calcification. The enhancement of lesion was mostly moderately to markedly inhomogeneous. High-risk small intestinal stromal tumors had more significant enhancement and vessels. Hepatic metastasis in 3 cases was detected. ConclusionCT features of HRGISTs can be found with certain characteristics, which may contribute to the diagnosis.
ObjectiveTo systematically review the effect and influence of gum chewing on the recovery of gastrointestinal function in gynecological patients after operation. MethodsEBSCO, MEDLINE, Web of Science, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials of gum chewing on gastrointestinal function recovery in patients after gynecological surgery from inception to September 30th, 2020. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies. RevMan 5.3 software was then used to perform the meta-analysis. ResultsA total of 9 studies were included, involving 962 patients. Meta-analysis results showed that the time of first flatus (MD=–8.34, 95%CI –10.72 to –5.95, P<0.000 01), the time of first defecation (MD=–14.97, 95%CI –29.28 to –0.66, P<0.04), and the recovery time of bowel sounds (MD=–5.83, 95%CI –10.15 to –1.51, P=0.008) of gum chewing group was significantly shorter than that of the control group, and the incidence of abdominal distension was decreased after gynecological surgery (RR=0.24, 95%CI 0.08 to 0.74, P=0.01). According to the results of subgroup analysis, the time of first flatus of the gum chewing group was significantly shorter than that of the control group in laparoscopy (MD=–5.43, 95%CI –7.12 to –3.73, P<0.000 01), laparotomy (MD=–10.46, 95%CI –13.56 to –7.97, P<0.000 01) and abdominal surgery (MD=–10.64, 95%CI –13.01 to –8.26, P<0.000 01); the first defecation time after laparotomy (MD=–29.18, 95%CI –46.03 to –12.33, P=0.000 7), and abdominal surgery (MD=–14.24, 95%CI –24.27 to –4.21, P=0.005) in chewing gum group was significantly shorter than that in the control group; however, there was no significant difference in the laparoscopy group (MD=–2.97, 95%CI –12.94 to 7.00, P=0.56). ConclusionsThe systematic review and meta-analysis shows that gum chewing after gynecological surgery can shorten the time of first flatus, first defecation, and first bowel movement, and reduce the incidence of abdominal distension. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.
ObjectiveTo sum up the diagnosis and treatment of adult ileal duplication with clinical cases from Peking Union Medical College Hospital (PUMCH). MethodsSix cases of adult ileal duplication admitted in our hospital from February 1996 to December 2010 were analyzed. Different assistant investigations were supposed to different patients due to the chief complaints including gastroscope, colonoscopy, abdominal CT scan, arteriography, 99Tcm radionuclide imaging, and double-balloon intestinal endoscope. None was made a definite diagnosis before operation with only one uncertain case. All cases received operation and pathological examination. Results All cases admitted were male. The chief complaints included intestinal bleeding, abdominalgia, intestinal obstruction, and abdominal mass. Five out of six patients received gastroscope, colonoscopy, and abdominal CT scan while three received mesenteric arteriography, but none was found any suggestion for ileal duplication. Even 99Tcm radionuclide imaging pointed out only two with abnormal abdominal bleeding. Three received doubleballoon intestinal endoscope, paying attention that only one discovered with ileal duplication. In a concluding, none was made a definite diagnosis before operation with only one uncertain case. All the cases received operation. The duplications of ileum in the length of 6-25 cm were found at the site of 11-100 cm proximal to ileocecum during the operation. Pathological report confirmed the clinical diagnosis of all cases with adult ileal duplications． Two cases were found with ectopic gastric mucosa, another two with diverticulum, and one with ectopic pancreas， in addition the remaining with inflammatory fibrous pseudotumor. Prognosis were good for all after operation. ConclusionsIleal duplications are rarely seen in adults, gender prefer male． Without specific clinical symptoms and inspections, definite diagnosis before operation is hard to make. But maybe doubleballoon intestinal endoscope and 99Tcm radionuclide imaging can give out positive result. Surgeons should be aware of this condition when performing abdominal exploration. Once discovered, resection is necessary.
