RESUMEN
Objective:To analyze the value of laminin γ2 (LAMC2) in the diagnosis of hepatocellular carcinoma (HCC) and the difference in patients with different types of microvascular invasion (MVI).Methods:A cohort of 100 patients with HCC who underwent surgical treatment at the Faculty of Hepato-Pancreato-Biliary Surgery, Chinese PLA General Hospital from January 2021 to March 2022 were prospectively enrolled. There were 80 males and 20 females, aged (55.7±11.1) years. The data of 17 patients with hepatic hemangioma without cirrhosis who underwent operation at the same hospital during the study period were collected to serve as the control group (6 males, 11 females), aged (42.8±9.8) years. LAMC2 in serum was determined by enzyme linked immunosorbent assay. The levels of alpha-fetoprotein (AFP) and LAMC2 were compared between the two groups, and receiver operating characteristic (ROC) curves were drawn to compare these two markers in the diagnosis of HCC. The LAMC2 of different MVI patients were compared.Results:The levels of LAMC2 and AFP were 1 334.2(838.9, 2 656.0) pg/ml and 19.0(4.6, 778.6) μg/L in the HCC group, which were significantly higher than 375.2(221.2, 691.7)pg/ml and 3.3(2.5, 3.5) μg/L in the control group ( Z=-4.32, -4.63, both P<0.001). The areas under the ROC curve were 0.829(95% CI: 0.748-0.892) for LAMC2 and 0.852(95% CI: 0.769-0.910) for AFP, and was 0.949(95% CI: 0.911-0.988) for using both in the diagnoses. The diagnostic efficacy of combining LAMC2 and AFP was significantly better than that of LAMC2 alone and AFP alone (area under ROC: Z=3.15, 3.07, P=0.002, 0.002). When the patients were divided into the M0 group (61 patients), the M1 Group (25 patients) and the M2 Group (14 patients) based on MVIs, the concentrations of LAMC2 were 1 168.6(834.3, 2 521.4) pg/ml, 942.2(614.0, 2 056.6) pg/ml and 3 128.4(1 852.7, 7 191.3) pg/ml, respectively. The level of LAMC2 in the M2 group was significantly higher than that in the M0 and M1 groups ( Z=-3.46, -3.32, P=0.001, 0.004). Conclusion:The diagnostic efficacy of LAMC2 combined with AFP for HCC was significantly higher than that of either LAMC2 alone or AFP alone. Serum LAMC2 levels were significant different among the groups of HCC patients with different types of MVI.
RESUMEN
Objective:To evaluate the hemostatic effect of self-expanding polyurethane foam in an animal model of fatal hepatic trauma and hemorrhage.Methods:The fatal liver trauma hemorrhage model with swine was established. Then the damage-controlled resuscitation was performed. Thirty minutes after injury, the experimental animals were randomly divided into the gauze packing group (GP), foam packing group (FP) and blank control group (BC). The survival time, vital signs, the bleeding volume, coagulation function and other lab indicators were recorded for 48 h. Liver histopathological examination was performed after death or execution.Results:All the three groups had severe hemorrhagic shock after modeling. The 48-h survival rate of the FP group and the GP group was significantly higher than that of the BC group (6/6 vs 4/6 vs 0/6). The average survival time of the FP group was not statistically different from that of the GP group [48 h vs (44.58±5.53) h, P>0.05], and was significantly longer than that of the BC group [48 h vs (1.64±0.17) h, P<0.01]. The bleeding volume of the FP group was significantly less than the GP group and BC group [(19.2±7.3) g/kg vs (41.3±8.6) g/kg, (51.5±7.3) g/kg, both P<0.01]. Compared with the GP group and the BC group, the cardiac output of the FP group was significantly improved [(5.00±0.53) L/min vs (4.13±0.41) L/min, (2.38±0.48) L/min, both P<0.05]. The coagulation function, liver and kidney function and blood lactate level of the FP group and the GP group were better than those of the BC group; the intra-abdominal pressure of the FP group was significantly higher than that in the GP group [(18.83±3.25) cmH 2O vs (3.83±1.47) cmH 2O, P<0.05]. There was no abnormal increased in intra-abdominal pressure in the BC group. According to the histopathology examination, there was no obvious secondary damage in the FP group. Conclusions:The application of self-expanding polyurethane foam for intraperitoneal packing to stop bleeding can effectively reduce the amount of bleeding in the fatal liver trauma hemorrhage model, effectively maintain vital signs, and improve the short-term survival rate.

RESUMEN
Objective@#To evaluate the application of intestinal stomas in mesenteric ischemia (MI) according to the concept of damage control surgery.@*Methods@#Clinical data of 59 MI patients received intestinal stomas at Jinling Hospital, Nanjing University School of Medicine from January 2010 to June 2017 were analyzed retrospectively. There were 41 male and 18 female patients aging of (51±14) years (ranging from 20 to 86 years). All the patients were divided to two groups according to the degree of bowel ischemia: acute MI group (AMI, bowel necrosis, n=43) and chronic MI group (CMI, bowel stricture, n=16). The medium time from onset to consult of AMI was 7(12) days (M(QR)) and the time of CMI was 80(51) days. After the resection of irreversible ischemic intestine, ostomy was carried out for all 59 patients. Patients received oral anticoagulation, enteral nutrition and succus entericus reinfusion therapy for about 6 months after discharge. Then definite surgery to restore digestive tract was preferred.@*Results@#In AMI group, APACHEⅡ score in admission was (16±3). The length of infarcted intestine resected was (160±95) cm, normal bowel left was (220±106) cm. Twelve patients had complications during first post-operation period including sepsis (n=8), acute renal failure (n=4), acute respiratory distress syndrome (n=4), short bowel syndrome (n=4). 30-day mortality was 18.6%. Total 30 patients received operation to restore the continuity of intestinal tract after 202(42) days and APACHEⅡ score was 4±2. Two patients suffered from sepsis and were cured after anti-infection. In CMI group, APACHEⅡ score was 16±3 and NRS2002 score was more than 3. The length of infarcted intestine resected was (43±33) cm. All patients had restored the continuity of intestinal tract after 176 (47) days. No major complications occurred during the first and second post-operation period.@*Conclusions@#According to damage control surgery, after early revascularization, patients with acute intestinal necrosis should be treated with infarcted bowel resection and stomas. Besides, second operation to restore the continuity of intestinal tract should be conducted after nutritional support for 6 months. Patients with ischemic enteropathy who cannot be corrected with severe malnutrition should achieve stomas during first operation.
RESUMEN
Objective@#To investigate the effect of Gradient treatment for acute superior mesenteric venous thrombosis (ASMVT).@*Methods@#Clinic data of 68 patients of ASMVT admitted in Department of General Surgery, Jinling Hospital, Medical School of Nanjing University from January 2009 to December 2014 were analyzed retrospectively. There were 50 male and 18 female patients with a mean age of (45±12) years. These patients were conducted by the stepwise treatment model (endovascular treatment-damage control surgery-surgical intensive care-intestinal rehabilitation treatment). Clinical outcomes and complications were compared during the follow-up period. Differences about bowel resection length of endovascular treatment and surgical procedures were evaluated with t test.@*Results@#In the 68 cases, 24 cases were cured simply by endovascular treatment, 19 cases received surgical procedures alone (group surgery). Twenty-five patients received endovascular treatment combined with surgical procedures (group combined), including 6 cases temporary abdominal closure. The overall mortality rate was 2.9% (2/68) during hospitalization. The range of bowel resection of group combined significantly reduced compared with group surgery ((92±14) cm vs. (162±27) cm, t=-2.377, P=0.022). During 1-year follow-up period, 4 cases suffered from short bowel syndrome, whom underwent surgery alone.@*Conclusions@#Early diagnosis and treatment is the key to treatment of ASMVT, the rapid improvement of intestinal ischemia is particularly important for prognosis. Combination therapy significantly save more residual small intestine and avoid short bowel syndrome. The selection of early gradient treatment can significantly reduce the mortality and improve the prognosis of ASMVT patients.

BACKGROUND:Short-segment pedicle screw technology has been extensively used in the treatment and repair of thoracolumbar burst fractures in the clinic. However, it requires further investigations whether bone graft through unilateral pedicle channel has superiority. ＜br> OBJECTIVE:To observe the perioperative effects on thoracolumbar burst fractures posterior by bone graft through unilateral pedicle channel with short pedicle screw segment fixation. ＜br> METHODS:Clinical data of 57 cases of thoracolumbar burst fractures without neurological symptoms treated by short segment pedicle screw internal fixation therapeutic method at the Department of Orthopedics, The First People’s Hospital of Yinchuan City from January 2009 to December 2013 were retrospectively analyzed. According to therapeutic methods, they were divided into three groups:pedicle screw fixation through injured vertebrae (n=21), unilateral pedicle screw fixation with vertebrae pedicle screw (n=19), and the short segment pedicle screw fixation with unilateral pedicle screw fixation and bone graft through pedicle channel (n=17). We observed the changes in operation time, the blood loss volume in operation, postoperative drainage blood (at the period of removing the drainage tube), injured vertebrae height’s ratio, the Cobb’s angel of injured vertebrae sagittal plane, vertebral canal encroachment rate and visual analog scale. ＜br> RESULTS AND CONCLUSION:(1) The unilateral pedicle screw fixation and bone graft by pedicle channel could prolong operation time and increase postoperative drainage blood volume (P＜0.05). (2) Three operation methods improved vertebral body height. (3)There were no significant differences in Cobb’s angle postoperation among the three groups (P>0.05). These data suggested that the bone graft through pedicle channel was not the factors to improve the spine kyphosis. (4) Bone graft by pedical channel improved vertebrae channel value. (5) Bone graft through pedicle channel combined with screw implantation could improve pain after treatment. These findings indicated that the therapeutic technology of short pedicle screw fixation on thoracolumbar vertebral burst fracture with unilateral pedicle fixation and bone graft through pedicle channel is a safe reliable operation method.

Objective To determine the effect of different surgical modalities on hemodynamics,systemic major organ injury and survival rate following superior mesenteric artery (SMA) injury in an attempt to search a modality that conforms to principles of damage control surgery (DCS).Methods SMA was exposed in 30 domestic hybrid pigs,leaving the blood flow blocked using non-invasive vessel forceps.The animals were divided into control group,primary anastomosis group (anastomosis group) and temporary intravascular shunt (TIVS) group according to random number table.TIVS group was further divided into three subgroups:shunting for 6 hours group (TIVS-6 h group),9 hours group (TIVS-9 h group) and 12 hours group (TIVS-12 h group).At each time point,the angiography was performed for evaluation of shunt patency; hemodynamic parameters were detected,terminal ileum and SMA samples were harvested for pathological analysis.Results All groups suffered extreme physiological conditions including hypothermia,severe acidosis,hypotension,low cardiac output and low oxygen supply.Less requirement of resuscitation fluid,faster restoration of SMA blood flow,earlier clearance of lactate,milder intestinal ischemia-reperfusion injury and higher survival rate were observed in TIVS-6 h and TIVS-9 h groups,compared with anastomosis group.Patency rate in TIVS-6 h,9 h and 12 h groups was 100％,50％ and 0％ respectively.Pathologic outcome of intestine revealed diffuse intestinal necrosis in TIVS-12 h group and reversible intestinal ischemia-reperfusion injury in TIVS-6 h and 9 h groups.Conclusion For SMA injury in severe hemodynamic disarrangement and jeopardized condition,TIVS shortens intestinal ischemia time,maintains systemic hemodynamic stability,relieves intestinal injury,improves early survival rate and keeps long-term intestine patency when compared with primary vascular anastomosis.
RESUMEN
Objective Refractory constipation,when complicated with megacolon,is difficult to manage.This study aimed to compare the clinical outcomes of different preoperative nutritional therapies on refractory constipation patients complicated with megacolon.Methods Patients of refractory mixed constipation complicated with megacolon receiving surgical interventions between 2006 Jun and 2011 Jun were enrolled.Perioperafive nutrition support was evaluated in terms of postoperative recovery.Results 78 constipation patients received therapies of NPM,gastrointestinal decompression and total parenteral nutrition during the first 7-14 days.34 patients retained intestine patency and after 2 weeks of enteral nutrition therapy,they (enteral nutrition group) successfully received selective surgery.The other 44 patients (non-enteral nutrition group) received emergency surgery after correcting homeostasis.The surgical procedures included Jinling procedure (n =45),Jinling procedure plus ileostomy (n =6),total colectomy plus ileum-rectum side-to-side anastomosis (n =18) and total colectomy plus ileostomy (n =9).EN group patients had a significant low rate of pneumonia (0％ vs 11.4％),anastomotic leakage (0％ vs 11.4％),anastomotic bleeding (2.9％ vs 18.2％) and ostomy (0％ vs 34.1％),compared with N-EN group.At one month follow up,the nutrition status was significantly better in EN group than that in N-EN group.Condusions Refractory constipation complicated with megacolon required surgical intervention.Recovering the intestinal patency and receiving enteral nutritional support therapy preoperatively benefits patient's recovery.
