Objective: To investigate the clinical efficacy of laparoscopic splenectomy combined with pericardial devascularization in the treatment of cirrhotic patients with cirrhotic portal hypertension. Methods: The retrospective and descriptive study was conducted. The clinicopathological data of 425 patients with cirrhotic portal hypertension who were admitted to Northern Jiangsu People′s Hospital Affiliated to Yangzhou University were collected. There were 289 males and 136 females, aged (53±11)years, with a range from 21 to 79 years. All the patients were allocated into 3 periods according to the operation time, including 100 patients of early period from February 2012 to March 2014, 156 patients of mature technology period from April 2014 to August 2016, and 169 patients of technology innovation period from september 2016 to December 2018. The patients of early period and mature technology period underwent laparoscopic splenectomy combined with pericardial devascularization, and the patients of technology innovation period underwent vagus nerve-preserving laparoscopic splenectomy combined with pericardial devascularization. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Patients were followed up by outpatient examination to detect the upper digestive rebleeding, gastric retention, and diarrhea up to March 2019. Sequential therapy of endoscopic variceal ligation (EVL) was slectively performed on patients based on results of gastroscopy. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using ANOVA, and paired comparison was analyzed using the t test. Measurement data with skewed distribution were represented as M (range), and comparison between groups was anlyzed using the Kruskal-Wallis rank sum test, and paired comparison was analyzed using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test and Fisher exact probability. Results: (1) Surgical situations: the operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion, cases with 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, χ²=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 (χ²=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 (χ²=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 (χ²=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.

The Enhanced recovery after surgery applies a series of evidence-based perioperative measures to accelerate patients recovery by reducing acute injury and complication.It is easy to lead to metabolic disturbance during perioperative period of hepatectomy which usually brings some serious trauma and is assiociated with strong and lasting surgical stress.In order to enhance recovery,enhanced recovery after surgery applies a series of key measures to easy the inflammatory reaction,relieve surgical physical and mental stress,keep homeostasis,reduce the rate of postoperative complications and readmission,save medical expenses at the same time.

Objective:To investigate the value of liver fibrosis serum markers in predicting esophagogastric variceal re-bleeding (EGVR) after laparoscopic splenectomy and azygoportal discon-nection (LSD).Methods:The prospective study was conducted. The clinical data of 155 cirrhotic portal hypertension patients with EGVR after LSD in the Clinical Medical College of Yangzhou University from September 2014 to January 2017 were selected. Observation indicators: (1) grouping situations of the enrolled patients; (2) risk factors analysis for postoperative EGVR; (3) prediction of postoperative EGVR; (4) follow-up. Follow-up was conducted using telephone interview, outpatient examination and hospitalization. Patients were followed up once every 3 months after operation to detect occurrence of EGVR and survival of patient up to January 2018. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data wite skewed distribution were represented as M(range), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups were conducted using the chi-square test or Fisher exact probability. Logistic regression model was used for multivariate analysis. The area under curve (AUC) of receiver operating characteristic (ROC) curve was used to estimate the diagnostic efficiency. The Youden index was used to determine the optimal cut-off point. Results:(1) Grouping situations of the enrolled patients. A total of 155 patients were selected for eligibility. There were 106 males and 49 females, aged (53±11)years. Of the 155 patients, there were 21 cases with EGVR in the postoperative 1 year and 134 cases without EGVR in the postoperative 1 year. The protein expression of laminin and collagen Ⅳ were 100.3(range, 16.1?712.2)μg/L and 68.4(range, 35.0?198.8)μg/L in patients with EGVR, vs 35.5(range, 2.0?521.2)μg/L and 43.5(range, 4.3?150.4)μg/L in patients without EGVR, showing significant differences between them ( Z=?4.55, ?4.52, P<0.05). (2) Risk factors analysis for postoperative EGVR. According to the Youden index, the optimal cut-off point of protein expression of laminin and collagen Ⅳ were 64.0 μg/L and 65.0 μg/L, respec-tively. Results of multivariate analysis showed that the protein expression of laminin ≥64.0 μg/L and the protein expression of collagen Ⅳ ≥65.0 μg/L were independent risk factors for postoperative EGVR ( odds ratio=9.69, 8.16, 95 confidence intervals as 3.05?30.82, 2.65?25.15, P<0.05). (3) Prediction of postoperative EGVR. Results of ROC curve showed that the AUC of laminin and collagen Ⅳ in predicting postoperative EGVR was 0.79 (95% confidence interval as 0.66?0.92), with sensi-tivity as 0.62 and specificity as 0.96. (4) Follow-up. All the 155 patients were followed up for 12(range, 1?12)months. During the follow-up, there were 21 of the 155 patients (13.55%) with post-operative EGVR, including 3 cases died of EGVR. Of the 21 patients with postoperative EGVR, there were 6 cases with postoperative EGVR during the first month after operation including 2 cases died, 5 cases with postoperative EGVR at postoperative 1?3 month, 6 cases with postoperative EGVR more than 3 month and less than 6 month after operation and 4 cases with postoperative EGVR at postoperative 6?12 months including 1 case died at postoperative 12 month. Conclusions:Laminin and collagen Ⅳ show satisfactory ability to predict EGVR after LSD.

Thrombosis is a multifactorial process with complex mechanisms and thrombosis-related diseases are extremely risky.At present, traditional or new types of anticoagulant drugs cannot completely reduce the risk of thrombosis, and these anticoagulant drugs have certain limitations and cannot meet clinical needs.In recent years, studies have found that intestinal microecology is closely related to many diseases, and The results show that it is involved in the regulation of thrombosis as the largest and most complex microecological system in the human body.In this review, we retrospect the current status and progress about the mechanism of intestinal microecology in thrombosis.Therefore, it provides a new idea and theoretical basis for the clinical application of intestinal microecology-based diagnosis and treatment in thrombosis-related diseases.
