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 analyze the reasons for misdiagnosis of gastrointestinal metastatic ovarian cancer, in order to increase the rate of correct diagnosis and treatment, and to investigate the prognostic factors. MethodsWe retrospectively analyzed the clinical features, pathological features and prognostic factors of 43 cases of metastatic ovarian carcinoma from gastrointestinal tract treated between 2004 and 2014. ResultsGastrointestinal metastatic ovarian cancer was characterized by the diversity of clinical manifestations and lack of specific symptoms. The common initial symptom was pelvic mass, frequently accompanied with gastrointestinal symptoms of ascites, anemia or weight loss, abdominal pain, bloating, gastrointestinal obstruction and bleeding. Signs and symptoms of primary and secondary tumor sites often coexisted with each other, leading to misdiagnosis. Univariate analysis showed that primary site, histological type, surgical treatment, the residual tumor debulking size, lymph node metastasis, tumor invasion and standard chemotherapy had significant impacts on the prognosis (P < 0.05). ConclusionsGastrointestinal metastatic ovarian cancer occurs in premenopausal women, often with ascites, abdominal pelvic masses as the first symptom. Primary tumor site is often ignored, and the initial correct diagnosis rate is low. Metastasis from stomach cancer is the most common, followed by colorectal cancer and esophageal cancer. Prognosis is correlated with the primary site, histological type, degree of differentiation, depth of invasion, lymph node metastasis and other factors. Radical surgery and chemotherapy can improve survival.
Objectives To summarize the regulation of glucagon-like peptide-1（GLP-1） level by metabolism of gastrointestinal nutrients. Methods Domestic and international publications online involving regulation of GLP-1 level by metabolism of gastrointestinal nutrients in recent years were collected and reviewed. Results GLP-1 influenced insulin secretion and sensitivity， and played a leading role in recovery of glucose metabolism. Metabolism of gastrointestinal nutrients regulated GLP-1 level. Studies had shown that GLP-1 was a candidate mediator of the effects of gastric bypass （GBP） for type 2 diabetes mellitus（T2DM）. Conclusions It plays an important role in anti-T2DM effects of GBP that metabolism of gastrointestinal nutrients regulated GLP-1 level. The corresponding studies can provide a novel clinical field to treat T2DM.

CT was the preferred imaging method. Functional magnetic resonance imaging, such as diffusion weighted imaging (DWI), had made some progress. The main criteria for evaluating the efficacy of GIST targeted therapy were RECIST 1.1 and Choi criteria.ConclusionCT and MRI play an important role in evaluating the efficacy of targeted therapy for GIST.
Objective To evaluate the role of CT in diagnosis of the gastrointestinal tract rupture after blunt abdominal trauma. MethodsTwenty preoperative CT scans and clinical data were obtained in 20 patients who subsequently had bowel ruptures verified surgically. CT findings were analyzed retrospectively in these patients. Retrospective interpretation was made by consensus of at least two radiologists. ResultsTwenty cases of CT scan showed intraperitoneal fluid (18 cases), pneumoperitoneum (18 cases), extravasations of gastrointestinal tract contents (2 cases), bowel wall findings (14 cases) and mesenteric injury (15 cases). Conclusion CT is fast, sensitive and noninvasive in diagnosis of the gastrointestinal tract rupture after blunt abdominal trauma.
目的 调查胃肠道疾病患者围手术期的疼痛状况，为建立无痛病房，优化医疗和护理服务提供依据。 方法 对2011年12月5日－2012年1月14日胃肠外科所有的新住院患者共227例，采用《四川大学华西医院住院病人疼痛现状调查问卷》进行调查，并同期调查胃肠外科27名主管医师对疼痛药物了解状况。 结果 有明确行为能力的216例患者完成调查问卷，其中有195例（90.28%）接受手术治疗，全身麻醉患者193例（占手术患者98.97%），诊断为胃肠道肿瘤163例（占手术人数的83.59%），手术等级为三级146例（占手术人数的74.87%）。有168例（86.15%）患者术后镇痛，在术后镇痛过程中使用镇痛泵156例（92.86%），其中75例（48.08%）认为镇痛泵镇痛“基本有效”，30例（19.23%）认为“无效”。39例术后未使用镇痛泵，其中20例（51.28%）认为“未使用术后镇痛泵”最主要原因为“不了解镇痛泵”。受调查的主管医师了解的疼痛药物仅占罗列药物52种的（20 ± 5.36）种。 结论 疼痛现象在胃肠道疾病围手术期患者中属普遍现象，由于不断增强镇痛意识和镇痛需求与相关知识缺乏的矛盾存在，及较少的医疗护理干预，导致镇痛效果不佳，影响了疼痛管理长效机制的建立和无痛病房的建设。

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.
