Objective: To compare the safety and efficacy of transmesenteric vein extrahepatic portosystemic shunt (TEPS) and transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of cavernous transformation of the portal vein (CTPV). Methods: The clinical data of CTPV patients with patency or partial patency of the superior mesenteric vein treated with TIPS or TEPS treatment in the Department of Vascular Surgery of Henan Provincial People's Hospital from January 2019 to December 2021 were selected. The differences in baseline data, surgical success rate, complication rate, incidence rate of hepatic encephalopathy, and other related indicators between TIPS and TEPS group were statistically analyzed by independent sample t-test, Mann-Whitney U test, and Chi-square test. Kaplan-Meier survival curve was used to calculate the cumulative patency rate of the shunt and the recurrence rate of postoperative portal hypertension symptoms in both groups. Results: The surgical success rate (100% vs. 65.52%), surgical complication rate (6.67% vs. 36.84%), cumulative shunt patency rate (100% vs. 70.70%), and cumulative symptom recurrence rate (0% vs. 25.71%) of the TEPS group and TIPS group were statistically significantly different (P < 0.05). The time of establishing the shunt [28 (2141) min vs. 82 (51206) min], the number of stents used [1 (12) vs. 2 (15)], and the length of the shunt [10 (912) cm vs. 16 (1220) cm] were statistically significant between the two groups (t = -3.764, -4.059, -1.765, P < 0.05). The incidence of postoperative hepatic encephalopathy in the TEPS group and TIPS group was 6.67% and 15.79% respectively, with no statistically significant difference (Fisher's exact probability method, P = 0.613). The pressure of superior mesenteric vein decreased from (29.33 ± 1.99) mmHg to (14.60 ± 2.80) mmHg in the TEPS group and from (29.68 ± 2.31) mmHg to (15.79 ± 3.01) mmHg in TIPS group after surgery, and the difference was statistically significant (t = 16.625, 15.959, P < 0.01). Conclusion: The best indication of TEPS is in CTPV patients with patency or partial patency of the superior mesenteric vein. TEPS improves the accuracy and success rate of surgery and reduces the incidence of complications.

To explore the differences in biological characteristics for the small gastrointestinal stromal tumors and the incidence of complications and recurrence between the traditional surgical treatment and endoscopic treatment.
 Methods: We collected the relevant clinical and pathological data from patients who were diagnosed as gastrointestinal stromal tumors with the diameter less than 2 cm by the Department of Pathology of Xiangya Hospital from January 2009 to December 2015. The complications and recurrence after the surgical treatment were analyzed.
 Results: In patients with small gastrointestinal stromal tumors, the proportion of female was higher than that of male (male:female=1:1.69). The median age for patient with this disease was 49 years old and it was more common in middle-aged and elderly. Most lesions were found in the stomach, followed by the esophagus and the small intestine. The small gastrointestinal stromal tumors occurred in the colon and rectum were rare. There was 60.3% (47/78) patients with abdominal pain, 7.7% (6/78) patients with hematochezia or melena, and 98.7% (78/79) with small gastrointestinal stromal tumors' mitotic count ≤5/50 HPF. The positive rates for CD, CD34, DOG-1, actin-smooth, and S-100 were 98.7%, 86.1%, 82.3%, 31.6%, and 24.1%, respectively. Three patients occurred surgical complications, 2 suffered recurrence during the follow-up. There was no significant difference in the incidence of complications and recurrence between the traditional surgical treatment and endoscopic treatment (P>0.05).
 Conclusion: Small gastrointestinal stromal tumors' malignant potential is low, and the recurrence and metastasis rate is low. Its biological behavior tends to be benign. The traditional surgical treatment and endoscopic treatment are both safe and effective for small gastrointestinal stromal tumor. Endoscopic treatment has the advantages in lower cost, shorter hospitalization time, and small trauma. Therefore, endoscopic treatment could be the first choice for small GIST resection under the condition of mature endoscopic technology.

OBJECTIVETo compare clinically relevant postoperative complications after open, laparoscopic, and robotic gastrectomy for gastric cancer.

METHODSClinical data of patients with gastric cancer who underwent gastrectomy between January 1, 2014 and October 1, 2016 at Chinese People's Liberation Army General Hospital were analyzed retrospectively. All the patients were diagnosed by upper endoscopy and confirmed by biopsy without distant metastasis. They were confirmed with R0 resection by postoperative pathology. Patients with incomplete data were excluded. The complications among open group, laparoscopic group and robotic group were compared. The continuous variables were analyzed by one-way ANOVA, and categorical variables were analyzed by χtest or Fisher exact test.

RESULTSA total of 1 791 patients (1 320 males and 471 females) were included in the study, aged from 17 to 98 (59.0±11.6) years, comprising 922 open, 673 laparoscopic and 196 robotic gastrectomies. There were no significant differences among three groups in baseline data (gender, age, BMI, comorbidity, radiochemotherapy) and some of operative or postoperative data (blood transfusion, number of lymph node dissection, combined organ resection, resection site, N stage, postoperative hospital stay). The blood loss in laparoscopic and robotic groups was significantly lower than that in open group[(185.7±139.6) ml and (194.0±187.6) ml vs. (348.2±408.5) ml, F=59.924, P=0.000]. The postoperative complication occurred in 197 of 1 791(11.0%) patients. The Clavien-Dindo II(, III(a, III(b, IIII(a, and IIIII( complications were 5.5%, 4.0%, 1.2%, 0.1%, and 0.2% respectively. The anastomotic leakage (2.4%), intestinal obstruction(1.3%) and pulmonary infection(1.2%) were the three most common complications, followed by wound infection(0.8%), cardiovascular disease(0.7%), anastomotic bleeding (0.7%), delayed gastric emptying (0.6%), duodenal stump fistula(0.5%), intraperitoneal hemorrhage (0.5%), pancreatic fistula (0.3%), intra-abdominal infection(0.2%), chylous leakage (0.1%) and other complications(1.7%). There were no significant differences among three groups as the complication rates of open, laparoscopic and robotic gastrectomy were 10.6%(98/922), 10.8%(73/673) and 13.3%(26/196) respectively (χ=1.173, P=0.566). But anastomotic leakage occurred more common after laparoscopic and robotic gastrectomy compared to open gastrectomy [3.1%(21/673) and 5.1%(10/196) vs. 1.3%(12/922), χ=12.345, P=0.002]. The rate of cardiocerebral vascular diseases was higher in open group[1.3%(12/922) vs. 0.1%(1/673) and 0, χ=8.786, P=0.012]. And the rate of anastomotic bleeding was higher in robotic group [2.0%(4/196) vs. open 0.4%(4/922) and laparoscopic 0.6%(4/673), χ=6.365, P=0.041]. In view of Clavien-Dindo classification, III(a complications occurred more common in laparoscopic group [5.5%(37/673) vs. open 3.3%(30/922) and robotic 2.6%(5/196), χ=6.308, P=0.043] and III(b complications occurred more common in robotic group [3.1%(6/196) vs. open 1.1%(10/922) and laparoscopic 0.7%(5/673), χ=7.167, P=0.028].

CONCLUSIONSMorbidities of postoperative complications are comparable among open, laparoscopic and robotic gastrectomy for gastric cancer. However, in consideration of the high difficulty of anastomosis, the minimally invasive surgery should be performed by more experienced surgeons.

Endoscopy plays an important role in the diagnosis and treatment of postoperative complications of gastric cancer. Endoscopic intervention can avoid the second operation and has attracted wide attention. Early gastric anastomotic bleeding after gastrectomy is the most common. With the development of technology, emergency endoscopy and endoscopic hemostasis provide a new treatment approach. According to the specific circumstances, endoscopists can choose metal clamp to stop bleeding, electrocoagulation hemostasis, local injection of epinephrine or sclerotherapy agents, and spraying specific hemostatic agents. Anastomotic fistula is a serious postoperative complication. In addition to endoscopically placing the small intestine nutrition tube for early enteral nutrition support treatment, endoscopic treatment, including stent, metal clip, OTSC, and Over-stitch suture system, can be chosen to close fistula. For anastomotic obstruction or stricture, endoscopic balloon or probe expansion and stent placement can be chosen. For esophageal anastomotic intractable obstruction after gastroesophageal surgery, radial incision of obstruction by the hook knife or IT knife, a new method named ERI, is a good choice. Bile leakage caused by bile duct injury can be treated by placing the stent or nasal bile duct. In addition, endoscopic methods are widely used as follows: abdominal abscess can be treated by the direct intervention under endoscopy; adhesive ileus can be treated by placing the catheter under the guidance of endoscopy to attract pressure; alkaline reflux gastritis can be rapidly diagnosed by endoscopy; gastric outlet obstruction mainly caused by cancer recurrence can be relieved by metal stent placement and the combination of endoscopy and X-ray can increase success rate; pyloric dysfunction and spasm caused by the vagus nerve injury during proximal gastrectomy can be treated by endoscopic pyloromyotomy, a new method named G-POEM, and the short-term outcomes are significant. Endoscopic submucosal dissection (ESD) allows complete resection of residual gastric precancerous lesions, however it should be performed by the experienced endoscopists.

Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy. The treatment of pulmonary artery embolism includes remittance of pulmonary arterial hypertension, anticoagulation, thrombolysis, operative thrombectomy, interventional therapy and extracorporeal membrane oxygenation (ECMO). Hemorrhage is a rarely occurred but relatively serious complication after bariatric surgery. The primary cause of anastomotic bleeding after laparoscopic gastric bypass is incomplete hemostasis or weak laparoscopic repair. The common bleeding site in laparoscopic sleeve gastrectomy is gastric stump and close to partes pylorica, and the bleeding may be induced by malformation and weak repair technique. Patients with hemodynamic instability caused by active bleeding or excessive bleeding should timely received surgical treatment. Anastomotic fistula in gastric bypass can be divided into gastrointestinal anastomotic fistula and jejunum-jejunum anastomotic fistula. The treatment of postoperative anastomotic fistula should vary with each individual, and conservative treatment or operative treatment should be adopted. Anastomotic stenosis is mainly related to the operative techniques. Stenosis after sleeve gastrectomy often occurs in gastric angle, and the treatment methods include balloon dilatation and stent implantation, and surgical treatment should be performed when necessary. Marginal ulcer after gastric bypass is a kind of peptic ulcer occurring close to small intestine mucosa in the junction point of stomach and jejunum. Ulcer will also occur in the vestige stomach after laparoscopic sleeve gastrectomy, and the occurrence site locates mostly in the gastric antrum incisal margin. Preoperative anti-HP (helicobacter pylorus) therapy and postoperative continuous administration of proton pump inhibitor (PPI) for six months is the main means to prevent and treat marginal ulcer. For patients on whom conservative treatment is invalid, endoscopic repair or surgical repair should be considered. Different surgical procedures will generate different related operative complications. Fully understanding and effectively dealing with the complications of various surgical procedures through multidisciplinary cooperation is a guarantee for successful operation.

BACKGROUNDAngiogenesis is the formation of new blood vessels to supply nutrients to tumors. Vascular endothelial growth factor (VEGF) and cluster of differentiation 34 (CD34) are important signaling proteins involved in angiogenesis. Many studies have demonstrated that VEGF and CD34 are related to tumor progression. This study focused on the relationship between VEGF, CD34, and perioperative hemorrhage in patients with gastric cancer.

METHODSTo observe the relationship between VEGF and CD34, we tracked 112 patients with advanced gastric cancer for 5 years to assess factors related to hemorrhage, using immunohistochemistry. The results were subjected to statistical analysis using a 2 × 2 contingency table, logistic regression, and receiver operating characteristic (ROC) test.

RESULTSThe concentrations of VEGF and CD34 were critically correlated with perioperative hemorrhage and neural invasion in patients with gastric cancer (P < 0.05). Expression of VEGF and CD34 was related (P < 0.05, χ2 = 6.834). VEGF and CD34 co-expression strongly increased the risk of preoperative bleeding (area under the ROC curve >0.7, P < 0.05).

CONCLUSIONSExpression of VEGF and CD34 was critically correlated with perioperative hemorrhage in gastric cancer patients. Co-expression of VEGF and CD34 could be an effective indicator for evaluating the risk of perioperative bleeding in gastric cancer patients.

BACKGROUND/AIMS: Diverticular bleeding can occasionally cause massive bleeding that requires urgent colonoscopy (CS) and treatment. The aim of this study was to identify significant risk factors for colonic diverticular hemorrhage. METHODS: Between January 2009 and December 2012, 26,602 patients underwent CS at our institution. One hundred twenty-three patients underwent an urgent CS due to acute lower gastrointestinal hemorrhage. Seventy-two patients were diagnosed with colonic diverticular hemorrhage. One hundred forty-nine age- and sex-matched controls were selected from the patients with nonbleeding diverticula who underwent CS during the same period. The relationship of risk factors to diverticular bleeding was compared between the cases and controls. RESULTS: Uni- and multivariate conditional logistic regression analyses demonstrated that the use of nonsteroidal anti-inflammatory drugs (odds ratio [OR], 14.70; 95% confidence interval [CI], 3.89 to 55.80; p<0.0001), as well as the presence of cerebrovascular disease (OR, 8.66; 95% CI, 2.33 to 32.10; p=0.00126), and hyperuricemia (OR, 15.5; 95% CI, 1.74 to 138.00; p=0.014) remained statistically significant predictors of diverticular bleeding. CONCLUSIONS: Nonsteroidal anti-inflammatory drugs, cerebrovascular disease and hyperuricemia were significant risks for colonic diverticular hemorrhage. The knowledge obtained from this study may provide some insight into the diagnostic process for patients with lower gastrointestinal bleeding.

Periampullary diverticulum is commonly found during endoscopy and can occur at any age although its prevalence increases with age. Periampullary diverticular bleeding is a rare and difficult to diagnose during clinical practice because of its unique appearance and location. This often can lead to massive bleeding and interfere with adequate bleeding control. Endoscopic management on duodenal diverticular bleeding is limited compared to colonic diverticular bleeding due to lack of experience. Herein, we report a case of active bleeding from a periampullary diverticulum during bile duct stone extraction diagnosed by side-viewing endoscope and successfully controlled using hemoclips without any complications.
