ABSTRACT
Objective:To investigate the efficacy of endoscopic histoacryl injection in cirrhotic patients with newly-developed esophagogastric varices (EGV) who have previously undergone splenectomy combined with pericardial devascularization.Methods:From January 2015 to January 2020, 125 cirrhotic patients with EGV treated with endoscopic histoacryl injection at the Department of Gastroenterology, Jinling Hospital, Medical School of Nanjing University, were included in the retrospective analysis. There were 45 patients in the group of splenectomy combined with pericardial devascularization (splenectomy group for short) and 80 patients in the non-splenectomy group. The efficacy of endoscopic treatment, postoperative variceal improvement, rebleeding rate, and complications were analyzed between the two groups.Results:Endoscopic histoacryl injection was successfully completed in all 125 patients, and the median volume of histoacryl was 4.5 mL. The overall effective rate in splenectomy and non-splenectomy group was 80.0% (36/45) and 57.5% (46/80), respectively. The difference in the number of significantly effective, effective, and ineffective cases between the two groups was statistically significant (16, 20, 9 cases, and 20, 26, 34 cases, respectively, χ 2=6.469, P=0.039). Two and 14 patients developed rebleeding in the splenectomy group and non-splenectomy group, respectively; and the difference in the rebleeding rate between the two groups was statistically significant (4.4% VS 17.5%, Log-rank P=0.039). No patient died within 1 year in either group, and no serious complications such as ectopic embolism occurred. Conclusion:After splenectomy combined with pericardial devascularization in cirrhotic patients with EGV and hypersplenism, the application of histoacryl has better short-term efficacy and can significantly reduce the rebleeding rate compared with the non-splenectomy group.
ABSTRACT
Objective:To study the risk factors of early postoperative portal vein thrombosis (PVT) after salvage devascularization for failed endoscopic therapy.Methods:A retrospective analysis was conducted on the clinical data of 525 cirrhotic patients who underwent pericardial devascularization for portal hypertension and esophagogastric variceal bleeding at the Department of General Surgery, Beijing Ditan Hospital, Capital Medical University from January 2012 to January 2022. There were 435 males and 90 females, aged 47(37, 58) years old. These patients were divided into two groups based on whether PVT occurred after devascularization: the PVT group ( n=225) and the non-PVT group ( n=300). Clinical data including gender, age, portal vein diameter and postoperative platelet elevation level (PPEL) were studied and the related factors of PVT were analyzed by univariate analysis. Factors with statistically significant differences were included in logistic regression analysis. Results:Univariate analysis showed that the significant risk factors of PVT were the scores of the model of end-stage liver disease, platelets, portal vein diameter, endoscopic therapy, operation duration, surgical bleeding volume, intraoperative blood transfusion and PPEL on the first and third postoperative days (all P<0.05). Multivariate analysis showed that portal vein diameter ≥13 mm ( OR=6.000, 95% CI: 3.418-10.533), endoscopic injection ( OR=1.894, 95% CI: 1.196-2.998), operation duration ≥ 180 min ( OR=8.520, 95% CI: 5.333-13.554), PPEL ≥ 20×10 9/L on the first postoperative day ( OR=2.125, 95% CI: 1.306-3.456) and PPEL≥50×10 9/L on the third postoperative day ( OR=1.925, 95% CI: 1.192-3.109) increased the risk of PVT (all P<0.05). Conclusion:The diameter of portal vein, endoscopic treatment, operation duration and PPEL on the first and third days after operation were independent risk factors of early postoperative PVT development.
ABSTRACT
Objective To investigate the characteristics of hemodynamics of proper hepatic artery and portal vein after splenectomy and devascularization. Methods The clinical data of 103 patients with portal hypertension who underwent splenectomy and devascularization in the Capital Medical University-Affiliated You'an Hospital from April 2014 to February 2019 were retrospectively analyzed. Their hemodynamics of the proper hepatic artery and portal vein were recorded before and 1 week-, and 1-, 3-, 6-, 12-, and 24-months after surgery and then statistically analyzed. Continuous data with normal distribution were compared using paired-samples t test. Results Compared with the before surgery data, the portal vein diameter, portal vein flow, maximum velocity, and average velocity of the portal vein were all significantly decreased 1-week-, 1-, 3-, 6-, 12-, and 24-months after splenectomy and devascularization (all P < 0.05). The blood flow and velocity of the proper hepatic artery was significantly increased 1 week and 1 month after surgery (all P < 0.05); however, there was no statistically significant difference at 3-, 6-, 12-, and 24-months after surgery. Conclusion The diameter, flow, and flow velocity of the portal vein after splenectomy and devascularization were significantly lower than those before surgery, whereas the proper hepatic artery flow and flow velocity were increased within 1 month after surgery and then returned back to the pre-surgery levels 3 months after surgery.
ABSTRACT
Objective:To investigate the computed tomography (CT) examination anato-mical features and clinical significance of paraesophageal vein (PEV) in portal hypertension.Methods:The retrospective and descriptive study was conducted. The clinical data of 173 patients with portal hypertension who were admitted to the People's Hospital of Ningxia Hui Autonomous Region from January 2018 to June 2021 were collected. There were 124 males and 49 females, aged from 22 to 71 years, with a median age of 47 years. Observation indicators: (1) preoperative CT examinations; (2) surgical situations; (3) follow-up. Follow-up was conducted using outpatient examination to detect surgical effects once every 3 months within postoperative 6 months and once every 6 months after postoperative 6 months. The follow-up was up to June 2021. Measurement data with skewed distribution were represented as M(range) and count data were described as absolute numbers. Results:(1) Preoperative CT examinations. The CT detection rate of PEV in the 173 portal hyper-tension patients was 52.60%(91/173). Of 173 patients, 82 cases were negative with PEV and 91 cases were positive with PEV. Of the 91 patients who were positive with PEV, there were 46 cases with paraesophageal varices, 24 cases with thick PEV, 21 cases with thin PEV, 8 cases without esophageal varices and 83 cases accompanied with esophageal varices. Of the 83 patients who were accom-panied with esophageal varices, there were 44 cases with PEV converged alone with azygos vein or semiazygos vein, 39 cases with paraesophageal varices formed above the diaphragm confluent with esophageal varices into azygos vein. (2) Surgical situations. All the 173 patients underwent surgery successfully, including 8 cases undergoing splenectomy, 86 cases undergoing splenectomy combined with modified complete devascularization, 35 cases undergoing splenectomy combined with spontaneous gastrorenal shunt reconstructing devascularization, 41 cases undergoing splenectomy combined with PEV preserving devascularization and 3 cases undergoing splenectomy combined with PEV ring constriction. None of 173 patients had surgical relative death, 67 cases had complica-tions, including 3 cases undergoing splenectomy, 29 cases undergoing splenectomy combined with modified complete devascularization, 11 cases undergoing splenectomy combined with spontaneous gastrorenal shunt reconstructing devascularization, 23 cases undergoing splenectomy combined with PEV preserving devascularization and 1 case undergoing splenectomy combined with PEV ring constriction underwent complications. (3) Follow-up. Of the 173 patients, 159 cases were followed up for 6 to 42 months, with a median follow-up time of 28 months. In the 7 cases undergoing splenectomy who were followed up, there were 6 cases without esophageal varices and 1 case with recurrence of esophageal varices. In the 79 cases undergoing splenectomy combined with modified complete devascularization who were followed up, there were 5 cases without esophageal varices, 67 cases with mild to moderate residual of esophageal varices, 5 cases with severe residual of esophageal varices, 1 case with recurrence of esophageal varices and 1 case with recurrence of esophageal varices hemorrhage. In the 34 cases undergoing splenectomy combined with sponta-neous gastrorenal shunt reconstructing devascularization who were followed up, there were 7 cases without esophageal varices and 27 cases with mild to moderate residual of esophageal varices. In the 36 cases undergoing splenectomy combined with PEV preserving devascularization who were followed up, there were 4 cases without esophageal varices, 21 cases with mild to moderate residual of esophageal varices, 5 cases with severe residual of esophageal varices, 4 cases with recurrence of esophageal varices and 2 cases with recurrence of esophageal varices hemorrhage. In the 3 cases undergoing splenectomy combined with PEV ring constriction who were followed up, there were 2 cases with mild to moderate residual of esophageal varices, 1 case with severe residual of esophageal varices.Conclusions:The CT detection rate of PEV in portal hypertension patients is >50% and the internal diameter and distribution of blood vessels are different in patients. CT examination anatomical features of PEV can be used to guide the formula-tion of surgical methods.
ABSTRACT
Objective:To compare the clinical efficacy of splenorenal shunt and traditional devascularization in the treatment of portal hypertension.Method:The clinical data of 109 patients with portal hypertension due to hepatitis B cirrhosis undergoing splenorenal shunt and traditional devascularization at Affiliated Hospital of Nantong University from Jan 2012 to Nov 2021 were retrospectively analyzed.Results:The operation time (208±43) min in shunt group was longer than that of (172±53) min in devascularization group ( t=-3.677, P<0.05). The intraoperative blood loss of (131±89) ml and postoperative hospital stay (21±6) d in shunt group were not significantly different from those of (164±109) ml and (21±8) d in devascularization group ( t=1.621, P>0.05; t=-0.403, P>0.05). There was no significant difference in the incidence of moderate to severe ascites, intraabdominal hemorrhage and hepatic encephalopathy between the two groups ( χ2=0.973, 0.830, 0.095, all P>0.05). The rebleeding rate in shunt group (5%) was lower than that in devascularization group (28%) ( χ2=5.280, P<0.05). The operation method was an independent predictor of rebleeding. The 1-, 2-, 3-, and 5-year cumulative survival rates in the shunt group were 95%, 94%, 91% and 88%, and in devascularization group were 95%, 88%, 85% and 73%. Rebleeding was an independent risk factor affecting the survival rate, and the risk of death in patients with postoperative rebleeding. Conclusion:Compared with devascularization, splenorenal shunt has obvious advantages in reducing postoperative rebleeding rate and prolonging survival time.
ABSTRACT
Objective:To investigate the clinical value of totally laparoscopic exclusion of splenic artery aneurysm combined with pericardial devascularization for portal hypertension com-plicated with splenic aneurysm.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 17 patients with portal hypertension complicated with splenic aneurysm who were admitted to 2 medical centers (15 cases in Shenzhen University General Hospital and 2 cases in Wuhan First Hospital) from January 2013 to May 2020 were collected. There were 7 males and 10 females, aged (59±14)years. All patients underwent totally laparoscopic exoclusion of splenic artery aneurysm combined with pericardial devascularization. Observation indicators : (1) surgical and postoperative conditions; (2) complications; (3) follow-up. Follow-up was conducted by out-patient examiantion and telephone interview to detect the effect of exclusion of arterial tumor, and blood re-flow, portal vein thrombosis and survival of patients 3 months after operation. The follow-up was up to December 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Results:(1) Surgical and postoperative conditions. All 17 patients successfully completed the operation, without perioperative death. The operation time, volume of intraoperative blood loss of 17 patients were (181±30)minutes, 187(range, 90?420)mL. The white blood cell count, red blood cell count, hemoglobin, serum albumin were (9±4)×10 9/L, (3.5±0.9)×10 12/L, (86±17)g/L, (36±7)g/L on the postoperative day 3. Time to postoperative abdominal drainage tube removal and duration of post-operative hospital stay were (7±4)days and (11±4)days. (2) Complications. All 17 patients had ascites after surgery, which were improved after oral treatment with diuretics. There was no complication such as intra-abdominal hemorrhage, gastrointestinal fistula, pleural effusion, infection, abscess formation, fever and vascular embolism. (3) Follow-up. All the 17 patients were followed up for 28.6(range, 7.0?84.0)months. During the follow-up, the splenic aneurysm cavity of all patients was completely isolated, no blood re-flow and no portal vein thrombosis was observed, and no patient died.

ABSTRACT
Portal vein thrombosis is a common complication after esophagogastric devascularization and splenectomy (EDS), with concealment and potential risks, which limited the therapeutic effect. The patients undergoing EDS are often accompanied by severe liver cirrhosis, whose abnormal hemostasis poses a dilemma for antithrombotic therapy. This article reviewed on the research progress of hemostasis of these patients, and risk factors, mechanism, prevention, therapy of post-EDS portal vein thrombosis.
ABSTRACT
Objective:To study the impact of anticoagulant therapy starting at different platelet levels on the incidences of portal vein thrombosis (PVT) after splenectomy and devascularization.Methods:From January 2014 to January 2017, 125 patients with liver cirrhosis and portal hypertension underwent splenectomy and pericardial devascularization in Beijing Ditan Hospital, Capital Medical University. All patients routinely received anticoagulant therapy. There were 85 patients who had a platelet count greater than >100×10 9/L (the study group) and 40 patients who had a platelet count greater than >300×10 9/L (the control group). The incidence of PVT was compared between the two groups. Results:A total of 125 patients were included in the study, including 91 males and 34 females, aged 20-59 years. Age, gender, preoperative platelet level, preoperative splenic vein and portal vein width, preoperative coagulation function, preoperative liver function (Child classification), preoperative esophageal and gastric varices, operation time, preoperative bleeding time, preoperative venous blood flow velocity, coagulation function 1 week and 2 weeks after operation between the two groups were not significantly different (all P>0.05). Of 125 patients undergoing splenectomy and pericardial devascularization, PVT was not found in all patients before operation. The incidence of PVT was 39.2% (49/125) within one month after operation. Among the 85 patients in the study group, 28 patients developed PVT, and the incidence of thrombosis was 32.9% (28/85). In the control group, 21 patients developed PVT, and the thrombosis rate was 52.5% (21/40). The difference was significant (χ 2=4.366, P=0.037). After anticoagulant therapy, the incidence of bleeding in the study group was 4.7% (4/85), and that in the control group was 5.0% (2/40), the difference was no significant ( P>0.05). Conclusion:Early anticoagulation (platelet >100×10 9/L) does not increase the risk of postoperative bleeding, but can reduce the incidence of PVT.
ABSTRACT
Objective:To determine the clinical efficacy of selective decongestive devascularization of gastrosplenic (SDD-GSR) and splenectomy combined with pericardial vascularization in the treatment of portal hypertension in cirrhosis.Methods:A total of 134 patients with cirrhosis portal hypertension admitted to the First Affiliated Hospital of Wenzhou Medical University were enrolled in the study, including 102 males and 32 females, with an average age of 51 years. Of 61 cases of SDD-GSR were included in the SDD-GSR group, and 73 cases of splenectomy combined with pericardial vascularization were included in the control group. Preoperative and postoperative white blood cell count, platelet count, Child-Pugh grade of liver function, free portal pressure (FPP) and postoperation tomplication were analyzed in the two groups. Operation time, intraoperative blood loss, free portal pressure (FPP), Child-Pugh grade of liver function, preoperative and postoperative white blood cell count, platelet count, and postoperative complications were analyzedin the two groups.Results:The operation time and intraoperative blood loss of SDD-GSR group were 165 (110, 198) min and 280 (100, 650) ml, which were lower than those of control group [190 (135, 605) min and 895 (300, 3 500) ml], the differences were statistically significant ( P<0.05). Postoperative FPP of SDD-GSR group and control group was 39 (35, 44) cmH 2O (1 cmH 2O=0.098 kPa) and 38 (34, 44) cmH 2O, respectively, which were lower than those before operation, with statistical significance (both P<0.05). Postoperative platelet count and white blood cell count in SDD-GSR group were lower than those in control group, and the differences were statistically significant (all P<0.05). The Child-Pugh grading of recent postoperative liver function in SDD-GSR group was better than that in control group, with statistical significance ( P<0.05). The complication rate (abdominal infection and portal vein thrombosis) of control group was higher than SDD-GSR group. Conclusion:SDD-GSR is better than splenectomy combined with pericardial vascularization since it has less intraoperative bleeding, obvious improvement of liver function and fewer complications, and it may be an effective surgical option for the treatment of portal hypertension of cirrhosis.
ABSTRACT
Objective:To investigate the clinical application and efficacy of laparoscopic splenectomy combined with disconnection in megalosplenia and portal hypertension.Methods:The clinical data of 58 patients with splenomegaly of portal hypertension treated in the Department of Hepatobiliary and Pancreatic Surgery of Huangshi Central Hospital of Eastern Hubei Medical Group from January 2016 to January 2020 were analyzed retrospectively, they were divided into laparoscopy group ( n=34) and laparotomy group ( n=24), Laparoscopic splenectomy combined with devascularization was performed in the laparoscopic group, and open splenectomy combined with devascularization was performed in the open group.The general data, operation time, intraoperative bleeding, postoperative exhaust time, postoperative hospital stay and the incidence of postoperative complications (abdominal bleeding, B/C pancreatic leakage, abdominal infection, etc.) were compared between the two groups. The measurement data obeying normal distribution was expressed by mean±standard deviation ( Mean± SD), and the t test was used comparison between groups, and the chi-square test or Fisher exact probability was used comparison between enumeration data. Results:The surgery was successful in both two groups. 2 cases in the laparoscopic group were converted to laparotomy, There was no death in perioperative period.The operation time of laparoscopy group was (205.3±28.6) min and that of laparotomy group was (156.4±20.7) min, which was significantly longer than that of laparotomy group ( P=0.012). The intraoperative bleeding volume of laparotomy group was (327.2±39.5) mL, which was significantly higher than that of laparoscopy group (246.5±32.3) mL. there was significant difference between the two groups ( P<0.05). The postoperative exhaust time and postoperative hospital stay in the laparoscopic group were (2.6±1.4) d and (9.7±2.3) d, the laparotomy group were (3.8±1.5) d and (12.9±2.7) d respectively. The laparoscopy group was shorter than the laparotomy group. The difference between the two groups was statistically significant ( P<0.05). There were 0 case of abdominal bleeding, 2 cases of B/C pancreatic leakage and 3 cases of abdominal infection in the laparoscopic group, 1 case of abdominal bleeding, 2 cases of B/C pancreatic leakage and 5 cases of abdominal infection in the open group. The incidence of postoperative complications in the laparoscopic group was lower than that in the open group, but there was no significant difference between the two groups( χ2=2.807, P=0.088). Conclusions:Laparoscopic splenectomy combined with devasculation is safe and feasible, with advantages such as little trauma, quick recovery of postoperative intestinal function and short hospital stay, which benefit patients. However, the operation is difficult and requires high technical and psychological quality of surgeons.

ABSTRACT
ObjectiveTo investigate the clinical effect of laparoscopic splenectomy and pericardial devascularization (LSPD) in patients with portal hypertension and the long-term effect of LSPD. MethodsA total of 40 portal hypertension patients with Child-Pugh A/B liver function who received LSPD in The First Hospital of Jilin University from August to December 2017 were enrolled as surgical group, and 44 portal hypertension patients with Child-Pugh A/B liver function who received conservative treatment during the same period of time was enrolled as internal medicine group. The patients were followed up to June 30, 2019, and liver function parameters, upper gastrointestinal bleeding, and portal vein thrombosis were recorded for all patients at each time point. The t-test was used for comparison of normally distributed continuous data between two groups; an analysis of variance was used for comparison between multiple groups, and the Bonferroni test was used for further comparison between two groups. The Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution; between multiple groups, and the Mann-Whitney U test was used for further comparison between two groups. The chi-square test was used for comparison of categorical data between groups. ResultsAt 6, 12, and 24 months after discharge, compared with the internal medicine group, the surgical group had a significantly higher level of cholinesterase (t=3.527, 3.849, and 5.555, all P＜0.05) and a significantly lower Child-Pugh score (t=2.498, 2.138, and 2.081, all P＜0.05). Compared with the internal medicine group at 12 and 24 months after discharge, the surgical group had a significantly higher level of albumin (t=3.120 and 2.587, both P＜0.05) and a significantly lower incidence rate of upper gastrointestinal bleeding (χ2=4.947 and 5.155, both P＜0.05). At 24 months after discharge, the surgical group had a significantly lower number of patients who had a significant increase in alpha-fetoprotein level than the internal medicine group (χ2=4.648, P=0.031). At 12 months after discharge, the surgical group had a significantly higher incidence rate of portal vein thrombosis than the internal medicine group (χ2=4.395, P=0.036). The surgical group had significant improvements in albumin (F=2.959, P=0.013), cholinesterase (F=11.022, P＜0001), prothrombin time (H=94.100, P＜0.001), and Child-Pugh score (F=3.742, P=0.003) from admission to 12 and 24 months after surgery. ConclusionIn portal hypertension patients with Child-Pugh A/B liver function, LSPD can improve liver function and reduce the incidence rate of upper gastrointestinal bleeding, and the high incidence rate of portal vein thrombosis can be effectively reduced by oral aspirin and rivaroxaban.
ABSTRACT
Gastroesophageal variceal bleeding and hypersplenism caused by portal hypertension seriously threaten the life of patients with liver cirrhosis. At present, devascularization is still one of the important surgical procedures for the treatment of portal hypertension; however, the development of the treatment methods such as drugs, endoscopy, and interventional treatment has caused the controversies over the role, surgical indications, and surgical timing of devascularization in the treatment of portal hypertension, as well as whether splenectomy is needed. This article reviews the role of devascularization and related controversies and points out that devascularization is still irreplaceable. Individualized, comprehensive, and minimally invasive treatment regimens should be developed for portal hypertension, so as to bring maximum benefits to patients with minimal invasiveness.
ABSTRACT
Background: Liver cirrhosis complicated with esophageal and gastric variceal bleeding is a commonly seen critical illness. Gastrointestinal endoscopy is widely applied for bleeding control and prevention of rebleeding. Aims: To investigate the timing of re-treatment of endoscopic selective varices devascularization (ESVD) for treatment of esophageal and gastric varices presenting as Sarin type GOV1 and GOV2. Methods: Forty-eight cirrhotic patients with GOV1 or GOV2 varices and a history of bleeding admitted from October 2018 to September 2019 at Jinhua Municipal Central Hospital were enrolled and underwent ESVD therapy for secondary prevention. After the first ESVD procedure, patients were randomly allocated into two groups, and received the re-treatment 2 weeks (Group A) and 4 weeks (Group B) later, respectively. All patients were followed up for 6 months and the efficacy of ESVD, as well as the rebleeding rate and the mortality rate were compared between the two groups. Results: There was no significant difference in devascularization of varicose veins between Group A and Group B (76.9% vs. 81.8%, P>0.05). The incidence of rebleeding in Group A was significantly lower than that in Group B during the 6-month follow-up (11.5% vs. 36.4%, P<0.05). No death occurred in both groups. Conclusions: ESVD is effective for secondary prevention of GOV1 and GOV2 variceal bleeding. With regard to the timing of re-treatment, short-term (2 weeks postoperatively) re-treatment might reduce the probability of rebleeding because it could deal with the high risk and vulnerable bleeding vessels earlier.
ABSTRACT
Describimos un caso de teratoma sacro-coxígeo gigante diagnosticado a las 21 semanas de gestación. Debido a los signos de robo vascular y de insuficiencia cardíaca fetal a las 24 semanas de gestación, se planteó la esclerosis del vaso nutricio por medio de laser Diodo. El procedimiento se realizó mediante punción percutánea guiada por ecografía en tres oportunidades, a las 25 semanas, a las 27 y a las 30 semanas. No hubo efecto secundario inmediato post tratamiento. La desvascularización fue parcial, debido a la híper-vascularización periférica de la masa. Los signos de insuficiencia cardíaca fetal se normalizaron después de 1 semana con disminución de crecimiento del tumor. El parto se realizó por cesárea a las 34 semanas, por rotura prematura de membranas y trabajo de parto avanzado en presentación pelviana. Tras 6 horas posteriores a su nacimiento se realizó cirugía de exceresis tumoral por técnica convencional, donde se extirpó por completo el teratoma sacrocoxígeo con un peso total de 630 gramos, material que se envió a anatomía patológica, cuyo diagnóstico final fue teratoma inmaduro grado III. Conclusión: La cirugía mínimamente invasiva con esclerosis del vaso nutricio parece mejorar el resultado perinatal en casos de teratoma sacro-coxígeo (TSC) fetal de alto riesgo. La identificación y el tratamiento temprano nos pueden dar resultado exitoso
We describe a case of giant sacrococcygeal teratoma (SCT) diagnosed at 21 weeks of gestation. Due to the signs of vascular steal and fetal heart failure at 24 weeks of gestation, sclerosis of the nutrient vessel was proposed by a laser diode. The procedure was performed by percutaneous puncture guided by ultrasound on three occasions, at 25 weeks, at 27 and at 30 weeks. There was no immediate side effect after treatment. The devascularization was partial, due to the peripheral hypervascularization of the mass. Signs of fetal heart failure normalized after 1 week with decreased tumor growth. Delivery was performed by cesarean at 34 weeks, due to premature rupture of the membranes and advanced labor in pelvic presentation. Six hours after birth, tumor excision was performed using a conventional technique, in which SCT with a total weight of 630 grs was completely removed, material that was sent to the pathological anatomy. Final diagnosis was immature teratoma grade III. Conclusions: Minimally invasive surgery with sclerosis of the nutrient vessel seems to improve the perinatal outcome in cases of high-risk fetal SCT. Identification and early treatment can give us a successful outcome

conversion to open surgery,and cases with emergency operation for bleeding were (187±46) minutes,150 mL (range,50-1 300 mL),2,2,1 for patients of early period,(164±22)minutes,50 mL (range,30-100 mL),1,1,1 for patients of mature technology period,and (150± 18)minutes,50 mL (range,10-300 mL),0,0,0 for patients of technology innovation period,respectively.There were significant differences in the operation time and volume of intraoperative blood loss between the three groups (F=55.482,x2 =94.620,P＜0.05).There was no significant difference in the cases with intraoperative blood transfusion,cases with conversion to open surgery,or cases with emergency operation between the three groups (P＞0.05).(2) Postoperative situations:425 patients had oral aspirin enteric-coated tablets for prevention of thrombus,with no perioperative death.Duration of postoperative hospital stay,cases with portal vein thrombosis at postoperative 7 days,cases with pancreatic fistula,cases with pulmonary infection,and cases with abdominal infection were (11.0±2.9) days,46,2,1,0 for patients of early period,(9.9±.1.7)days,81,3,0,0 for patients of mature technology period,and (8.8±1.3)days,83,2,1,1 for patients of technology innovation period,respectively.There was a significant difference in the duration of postoperative hospital stay between the three groups (F =39.836,P ＜ 0.05),between patients of mature technology and patients of early period (t =3.329,P＜0.05),between patients of mature technology period and patients of technology innovation (t =6.502,P＜0.05).There was no significant difference in the cases with portal vein thrombosis at postoperative 7 days between the three groups (x2 =0.865,P ＞ 0.05) and no significant difference in the cases with pancreatic fistula,cases with pulmonary infection,or cases with abdominal infection between the three groups (P＞0.05).Patients with portal vein thrombosis at postoperative 7 days had oral aspirin enteric-coated tablets or warfarin for treatment.Patients with pancreatic fistula,pulmonary infection,and abdominal infection were cured and discharged after conservative treatment.(3) Follow-up:all the 425 patients were followed up for 1-72 months,with a median follow-up of 36 months.Of the 425 patients,261 underwent postoperative sequential therapy of EVL,including 133 patients of mature technology period and 128 patients of technology innovation period.The incidence rate of upper digestive rebleeding was 3.83％ (10/261) of the 261 patients undergoing postoperative sequential therapy of EVL and 17.68％ (29/164) of 164 patients without postoperative sequential therapy of EVL,showing a significant difference between them (x2 =23.185,P＜0.05).The incidence rates of gastric retention and diarrhea were 96.24％ (128/133) and 61.65％ (82/133) for 133 patients undergoing sequential therapy of EVL in mature technology period,and 1.56％ (2/128) and 3.91％(5/128) for 128 patients undergoing sequential therapy of EVL in technology innovation period,showing significant differences between them (x2 =233.876,97.883,P＜0.05).Conclusions It is safe and feasible of laparoscopic splenectomy combined with pericardial devascularization for patients with cirrhotic portal hypertension,and intraoperative vagus nerve-preserving can reduce volume of intraoperative blood loss and incidence of postoperative complications.
ABSTRACT
Objective To study the impact of surgical teamwork in totally laparoscopic splenectomy and pericardial devascularization (LSPD) in the treatment of portal hypertension,and advice on technical hints.Methods A retrospective study was conducted on the clinical features of eighty-four patients who underwent totally laparoscopic splenectomy and pericardial devascularization in the Second Affiliated Hospital of Kun Ming Medical University from January,2014 to December,2017.Results Totally laparoscopic procedures were performed successfully in 80 patients.The procedure was converted to hand-assisted laparoscopic splenectomy and pericardial devascularization in 3 patients because of uncontrollable bleeding.One patient who initially underwent laparoscopic cholecystectomy developed an intraoperative blood loss of 1 500 ml.The surgery was terminated and was continued one week later after stabilization of the patient.Of the 80 patients who underwent totally LSPD,the operation time ranged from 116.0 to 243.0 (146.0 ± 33.0) min.The intraoperative blood loss ranged from 60.0 to 600.0 (214.0 ± 31.0) ml.Routine coagulation function and portal vein color Doppler ultrasound examination carried out within 3 months after surgery detected postoperative portal vein thrombosis in four patients.They responded successfully to antiplatelet and anticoagulant therapy.There were no perioperative deaths,variceal bleeding,gastrointestinal fistula and infection.Conclusions With proper surgical steps and skilled laparoscopic technique carried out by an experienced team of surgeons,totally laparoscopic splenectomy and pericardial devascularization was safe and effective in treating portal hypertension.Strict perioperative management provided a guarantee for the safe operation.
ABSTRACT
At present,splenectomy and extensive esophagogastric devascularization is one of the effective treatments for relieving hypersplenism in patients with cirrhosis,relieving portal hypertension,and reducing upper gastrointestinal bleeding caused by rupture of esophagogastric varices.However,portal vein thrombosis is one of the most common serious complications of splenectomy and devascularization in patients with cirrhosis.Because of its high incidence and mortality of PVT,it has become the focus of disputes in the surgical field.In recent years,with the improvement of medical technology,many domestic and foreign scholars have conducted high-quality researches on the prevention of PVT in the perioperative period of splenectomy and devascularization.This paper summarized the research progress during recent years in combination with relevant literature.
ABSTRACT
Objective To investigate the efficacy and safety of preventive anticoagulant therapy at different time windows on formation of portal vein thrombosis after laparoscopic splenectomy and pericardial devascularization.Methods The study was performed as a randomized,prospective trial.83 patients with portal hypertension who underwent laparoscopic splenectomy and pericardial devascularization were divided into four groups:the non preventive anticoagulant group (n =21),the prophylactic anticoagulant group (n =23),the 24 hours of preventive anticoagulant group (n =19) and the 48 hours of preventive anticoagulant group (n =20).The incidences of postoperative portal vein thrombosis,the Yerdel grading,platelet count,APTT,and bleeding complications were studied.Results The incidences of portal vein thrombosis in the four groups were 100％,39.1％,47.3％,55％,respectively,and the difference among the 4 groups was significantly different (P ＜ 0.05).The incidences of portal vein thrombosis between the prophylactic anticoagulant group and the 24 hours of preventive anticoagulant group showed no significant difference (P ＞0.05),but the incidences of portal vein thrombosis after 48 hours of preventive anticoagulant group was significantly higher than the prophylactic anticoagulant group and the 24 hours of preventive anticoagulant group,respectively (P ＜ 0.05).Postoperative bleeding complications,platelet count and APTT after the operations showed no significant differences (P ＞ 0.05).However,the plasma level of D-dimer in the non preventive anticoagulant group was significantly higher than the preventive anticoagulant group (P ＜ 0.05).Conclusion Preventive anticoagulant therapy effectively reduced the incidence of portal vein thrombosis after laparoscopic splenectomy and pericardial devascularization,but it did not significantly increase the risk of postoperative bleeding complications.
