		                        			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.

		                        			OBJECTIVE:
		                        			To compare the effectiveness between the posterolateral approach and the posterolateral combined posteromedial approaches in the treatment of Mason type 2B posterior malleolar fracture.
		                        		
		                        			METHODS:
		                        			A retrospective analysis was performed on the clinical data of 79 patients with posterior ankle fracture who met the selection criteria between January 2015 and January 2022. There were 62 cases of Mason 2B Pilon subtype and 17 cases of avulsion subtype. Among Mason 2B Pilon subtype patients, 35 were treated with posterolateral approach (group A), 27 patients were treated with combined approach (group B). There was no significant difference in gender, age, injured side, cause of injury, time from injury to operation, preoperative hospital stay, preoperative visualanalogue scale (VAS) score, and intraoperative internal fixation between the two groups ( P>0.05). All patients with Mason 2B avulsion subtype were treated by posterolateral approach, including 7 males and 10 females, aged from 25 to 68 years, with an average of 46.1 years. The operation time, intraoperative blood loss, postoperative hospital stay, and complications were recorded. The reduction quality was evaluated by Ovadia deals radiographic score, and the ankle function and pain were evaluated by VAS score, American Orthopaedic Foot and Ankle Society (AOFAS) score, and ankle range of motion.
		                        		
		                        			RESULTS:
		                        			Mason 2B Pilon subtype: There was no significant difference in operation time, intraoperative blood loss, postoperative hospital stay, and follow-up time between the two groups ( P>0.05). The radiological evaluation of Ovadia deals in group A was significantly worse than that in group B ( P<0.05). The VAS score in the two groups significantly improved at each time point after operation, and the VAS score and AOFAS score further improved with the extension of time after operation, and the differences were significant ( P<0.05). Except that the AOFAS score of group A was significantly lower than that of group B at last follow-up ( P<0.05), there was no significant difference in VAS score and AOFAS score between the two groups at other time points ( P>0.05). At last follow-up, the ankle range of motion in group A was significantly less than that in group B ( P<0.05). There was no significant difference in the incidence of sural nerve injury, deep tissue infection, limitation of toe movement, and traumatic ankle arthritis between the two groups ( P>0.05). Mason 2B avulsion subtype: The operation time was (119.47±20.61) minutes and the intraoperative blood loss was 50 (35, 55) mL. Seventeen patients were followed up 13-25 months, with an average of 18 months. The Ovadia deals score was excellent in 10 cases, good in 6 cases, and poor in 1 case at 1 week after operation, and the excellent and good rate was 94.1%. All fractures healed in 8-18 weeks with an average of 12.35 weeks. There were 1 case of sural nerve injury and 3 cases of traumatic ankle arthritis after operation. No deep tissue infection or limitation of toe movement occurred. The VAS score decreased significantly and AOFAS score increased significantly with time, and the differences were significant between different time points before and after operation ( P<0.05). The ankle range of motion at last follow-up was (56.71±2.47)°.
		                        		
		                        			CONCLUSION
		                        			Compared with the posterolateral approach, the combined approach is a better choice for the treatment of Mason 2B Pilon subtype. If the posteromedial bone block does not affect the reduction of the medial malleolus, the posterolateral approach can achieve good effectiveness for Mason 2B avulsion subtype.

Chinese Journal of Contemporary Pediatrics 2023;25(10):1001-1007
		                        		
		                        			OBJECTIVES:
		                        			To investigate the risk factors and prognosis of hypotension within 72 hours after birth in extremely preterm infants.
		                        		
		                        			METHODS:
		                        			A retrospective analysis was conducted on clinical data of extremely preterm infants admitted to the Children's Hospital of Zhejiang University School of Medicine from January 2019 to April 2022. Based on the presence of hypotension within 72 hours after birth, the eligible infants were divided into a hypotension group (41 cases) and a normotension group (82 cases). The clinical characteristics, echocardiographic parameters within 72 hours after birth, and early complications were compared between the two groups. Multivariate logistic regression analysis was used to explore the risk factors for hypotension within 72 hours after birth, and receiver operating characteristic curve analysis was performed to evaluate the predictive value of relevant indicators for the occurrence of hypotension within 72 hours after birth in the preterm infants.
		                        		
		                        			RESULTS:
		                        			The proportion of infants who required medication or surgical closure of patent ductus arteriosus (PDA), the proportions of infants with intraventricular hemorrhage ≥ grade III and severe pulmonary hemorrhage, and the mortality rate within 7 days in the hypotension group were significantly higher than those in the normotension group (P<0.05). Multivariate logistic regression analysis showed that lower birth weight, larger PDA diameter, and hemodynamically significant PDA were risk factors for the occurrence of hypotension within 72 hours after birth in extremely preterm infants (P<0.05). The receiver operating characteristic curve analysis showed that the combination of birth weight, PDA diameter, and hemodynamically significant PDA had an area under the curve of 0.873 (95%CI: 0.802-0.944, P<0.05) for predicting hypotension within 72 hours after birth, with a sensitivity of 73.2% and specificity of 91.5%.
		                        		
		                        			CONCLUSIONS
		                        			Hypotension within 72 hours after birth is closely related to birth weight and PDA, and increases the risk of early severe complications and mortality in extremely preterm infants.

		                        			OBJECTIVE:
		                        			To investigate and analyze the risk factors of massive hemorrhage in patients with renal cell carcinoma and venous tumor thrombus undergoing radical nephrectomy and removal of venous tumor thrombus.
		                        		
		                        			METHODS:
		                        			From January 2014 to June 2020, 241 patients with renal cancer and tumor thrombus in a single center of urology at Peking University Third Hospital were retrospectively analyzed. All patients underwent radical nephrectomy and removal of venous tumor thrombus. The relevant preoperative indicators, intraoperative conditions, and postoperative data were statistically analyzed by using statistical software of SPSS 18.0. The main end point of the study was intraoperative bleeding volume greater than 2 000 mL. Logistic regression analysis was used to determine the relevant influencing factors. First, single factor Logistic regression was used for preliminary screening of influencing factors, and variables with single factor Logistic regression analysis P < 0.05 were included in multivariate Logistic regression. In all statistical analyses, P < 0.05 is considered statistically significant.
		                        		
		                        			RESULTS:
		                        			Among the 241 patients included, there were 60 cases of massive hemorrhage, 48 males and 12 females, with a median age of 62 years. The number of non-massive hemorrhage was 181. There were 136 males and 45 females, with a median age of 59 years. Univariate analysis showed that the clinical symptoms (both systemic and local symptoms, OR 2.794, 95%CI 1.087-7.181, P=0.033), surgical approach (open surgery, OR 9.365, 95%CI 4.447-19.72, P < 0.001), Mayo grade (Mayo 3-4, OR 5.257, 95%CI 2.806-10.886, P < 0.001), American Society of Anesthesiologists (ASA) score (ASA level 3, OR 2.842, 95%CI 1.338-6.036, P=0.007), preoperative hemoglobin (OR 0.978, 95%CI 0.965-0.991, P=0.001), preoperative platelet count (OR 0.996, 95%CI 0.992-1.000, P=0.037), maximum tumor thrombus width (OR 1.061, 95%CI 1.033-1.091, P < 0.001), Complicated with bland thrombus (OR 4.493, 95%CI 2.264-8.915, P < 0.001), adrenalectomy (OR 3.101, 95%CI 1.614-5.958, P=0.001), segmental resection of the inferior vena cava (OR 2.857, 95%CI 1.395-5.852, P=0.004). There was a statistically significant difference in these aspects(P < 0.05). Multivariate Logistic regression analysis showed that there was a statistically significant difference in surgical approach (open surgery, OR 6.730, 95%CI 2.947-15.368;P < 0.001), Mayo grade (Mayo 3-4, OR 2.294, 95%CI 1.064-4.948, P=0.034), Complicated with bland thrombus (OR 3.236, 95%CI 1.492-7.020, P=0.003).
		                        		
		                        			CONCLUSION
		                        			Combining the results of univariate and multivariate Logistic regression analysis, the surgical approach, Mayo grade, and tumor thrombus combined with conventional thrombus were associated risk factors for massive hemorrhage during surgery for renal cell carcinoma with tumor thrombus. Patients who undergo open surgery, high Mayo grade, and tumor thrombus combined with conventional thrombus are at a relatively higher risk of massive hemorrhage.

		                        			Although the treatment strategy of esophageal and gastric varices bleeding in portal hypertension has been diversified and multidisciplinary now,the surgical treatment represented by pericardial devascularization operation will still play an important and irreplaceable role in China. In order to standardize the surgical procedure,guide clinical practice and improve the level of surgical treatment of portal hypertension,Chinese Society of Spleen and Portal Hypertension Surgery,Chinese Surgical Society,Chinese Medical Association organized Chinese experts to formulate this consensus. The main contents include:the position of surgical treatment,surgical indications and contraindications,preoperative evaluation,key points and precautions of surgical procedure,perioperative treatment,prevention and treatment of postoperative complications. The consensus emphasizes the standardization of surgical treatment of portal hypertension,pay attention to the prevention and treatment of postoperative portal vein thrombosis,and expect to provide surgeons with clinical guidance.

Methods Electronic databases including PubMed, Embase, Ovid, WANFANG, VIP and CNKI were searched to identify all case reports of HS patients undergoing AVR surgery, using different combinations of search terms "Heyde syndrome", "gastrointestinal bleeding", "aortic stenosis", and "surgery". Three authors independently extracted the clinical data including the patients' characteristics, aortic stenosis severity, gastrointestinal bleeding sites, surgical treatments and prognosis. Results Finally, 46 case reports with 55 patients aging from 46 to 87 years, were determined eligible and included. Of them, 1 patient had mild aortic stenosis, 1 had moderate aortic stenosis, 42 had severe aortic stenosis, and 11 were not mentioned.

		                        			In recent years, in the absence of venous component, dilated, overlapping, and tortuous arteries forming a mass of arterial loops with a coil-like appearance have been defined as pure arterial malformation (PAM). It is extremely rare, and its etiology and treatment have not yet been fully elucidated. Here, we reported 2 cases of PAM with associated aneurysmal subarachnoid hemorrhage in this paper. Both patients had severe headache as the first symptom. Subarachnoid hemorrhage was found by CT and computed tomography angiography (CTA) and PAM with associated aneurysm was found by digital subtraction angiography (DSA). In view of the distribution of blood and the location of aneurysms, the aneurysm rupture was the most likely to be considered. Based on the involvement of the lesion in the distal blood supply, only the aneurysm was clamped during the operation. It used to be consider that PAM is safety, because of the presentation and natural history of previously reported cases. Through the cases we reported, we have doubted about "the benign natural history" and discussed its treatment. PAM can promote the formation of aneurysms and should be reviewed regularly. The surgical indications for PAM patients with aneurysm formation need to be further clarified. Management of PAM patients with ruptured aneurysm is the same as that of ruptured aneurysm. Whether there are indications needed to treat simple arterial malformations remains to be further elucidated with the multicenter, randomized controlled studies on this disease.

		                        			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.

		                        			Bronchogenic cyst occurring in the diaphragm is rare and thoracoscopic cyst resection is mainly effective treatment. The coronary artery bleeding after video-assisted thoracoscopic surgery (VATS) has never been described; here we report a case of left coronary artery injury after thoracoscopic itradiaphragmatic bronchogenic cyst resection, which may be caused by metallic troca or chest tube.

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.
