ABSTRACT

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.

ABSTRACT

Objective@#To examine the relative factors of transmural intestinal necrosis(TIN) during multidisciplinary stepwise management facilitating the decision making in patients with acute superior mesenteric vein thrombosis (ASMVT).@*Methods@#Clinical data of patients with ASMVT admitted to Department of General Surgery, Jinling Hospital from January 2009 to June 2017 were reviewed retrospectively. There were 52 males and 37 females, aging (45.9±12.6) years (range: 20 to 69 years). According to the postoperative pathological results and follow-up, the patients were divided into TIN group (n=31) and non-TIN group(n=58, including 18 cases of intestinal stricture). The related factors were compared between ASMVT patients with TIN and patients without TIN by univariate analysis using t test, U test and χ2 test accordingly, and factors with statistically significance were subsequently submitted to binary Logistic regression analysis. The predictive value and cut-off point of factors were evaluated by receiver operator characteristic(ROC) curve and area under the curve.@*Results@#In univariate analysis, smoking, hypertension, peritonitis, white blood cell count,haemoglobin, international normalized ratio, blood albumin, thrombosis of superior mesenteric branches vein, free intraperitoneal fluid, decrease of bowel wall enhancement and pneumatosis intestinalis were TIN risk factors (all P<0.05). According to the binary Logistic regression analysis, white blood cell count (OR=1.093, 95%CI: 1.010 to 1.182, P=0.027), thrombosis of the superior mesenteric branches vein (OR=11.519, 95%CI: 1.906 to 69.615, P=0.008), pneumatosis intestinalis (OR=11.140, 95%CI: 2.360 to 52.585, P=0.002) were independent relative factors of TIN in patients with AMI, and the area under the ROC curve of the above factors and predictive model was 0.759 (95%CI: 0.647 to 0.871), 0.745 (95%CI: 0.641 to 0.848), 0.737 (95%CI: 0.621 to 0.854), 0.909 (95%CI: 0.847 to 0.971), respectively. The cutoff value of white blood cell count was 18.1×109/L.@*Conclusion@#White blood cell levels, superior mesenteric vein branch thrombosis and pneumatosis intestinalis are independent predictors of TIN in ASMVT.

ABSTRACT

Gastric stem cells are adult stem cells found in the gastric tissues,which possess high self-renewal capability,proliferation rate and multiple differentiation capability.They can regenerate all the gastric mucosa epithelial cells.Gastric stem cells play an important role in the self-renewal and injury repair,making epithelium of gastric mucosa in the dynamic balance and maintaining the integrity of gastric mucosa.With the constant deepening of stem cell research,the application of gastric stem cells provides a new means for the study of gastric physiology and diseases.Since the first report by Barker in 2010,gastric organoids have soon become a model of interest and are highly desirable as tools for studying gastric diseases.As an optimal experimental model,gastric organoids are superior to animal model and conventional cell culture.Gastric organoids are comprised of all major types of gastric epithelial cells,represent the architecture and function remarkably similar to those of the gastric epithelium,faithfully recapitulating the functional gastric epithelium ex vivo.Especially gastric organoids derived from the human body,which allow the investigation of the function of human stomach in the ex vivo setting.In this review,research progresses of gastric stem cells and their application in establishment of gastric organoids are summarized.

ABSTRACT

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.

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the application of staged ileostomy and closure operation combined with nutritional support therapy in the treatment of chronic radiation intestinal injury(CRII).</p><p><b>METHODS</b>Clinical data of patients with definite radiation history and pathological diagnosis of CRII receiving treatment at Department of General Surgery, Jinling Hospital from January 2012 to December 2016 were retrospectively analyzed. Patients who were diagnosed with tumor recurrence during operation or by postoperative pathology were excluded. Patients undergoing stageI( ileostomy and stageII( closure operation combined with nutrition support therapy were enrolled to the cohort. Detailed scheme of stage I( ileostomy and therapeutic time were determined by clinical symptoms and nutritional status. While performing ileostomy, the removal of intestinal lesions depended on range and degree of intestinal injury. Nutritional support therapy and other symptom-relieving therapy were offered after surgery. Timing for stageII( closure operation was decided according to nutritional status of patients. Lesions of remaining intestine were determined during operation, then necessary intestinal resection and closure operation were performed. Adhesion classification of radiation intestinal injury (total five levels) proposed by our center was adopted to evaluate the level and range of intestinal lesions. Level 0 indicated no adhesion between injured intestinal loop and surrounding organs; level 1 indicated that the adhesion and fibrosis were limited to right pelvis; level 2 indicated that the adhesion included all pelvis and the adhesion was severe and difficult to divide; level 3 was the forward extension of level 2 adhesion, which was between injured intestinal loop and anterior pelvic wall; level 4 was the upward extension of level 3 adhesion, which was between injured intestinal loop and anterior abdominal wall. Clavien-Dindo classification (lower level means milder symptom) and complication comprehensive index(CCI, lower CCI means milder symptom) calculated by on-line program (http:∕∕www.assessurgery. com) were applied to estimate postoperative complications. Resected intestinal length, adhesion classification of radiation intestinal injury, postoperative complications and time to total enteral nutritional (TEN) of both surgeries and nutritional status (body mass index and serum albumin) were compared between stageI( ileostomy and stageII( closure operation.</p><p><b>RESULTS</b>Twenty-one patients were enrolled in the research with 2 males and 19 females. Primary tumor included 14 cervical cancers, 3 rectal cancers, 1 endometrial cancer, 1 ovarian carcinoma, 1 seminoma and 1 mixed germ cell tumor. Median interval between the end of radiation and radiation intestinal injury was 7(2 to 91) months and median interval between the incidence of radiation intestinal injury and ileostomy was 5(<1 to 75) months. Operative indications for ileostomy were obstruction in 14 cases (66.7%), intestinal internal fistula in 1 case (4.8%), intestinal outer fistula in 2 cases (9.5%), radiation proctitis in 3 cases (14.3%) and acute intestinal perforation in 1 case (4.8%). Average age of patients undergoing stageI( ileostomy was 48 (18 to 60) years with BMI (17.0±2.7) kg/m and serum albumin (36.8±5.2) g/L. Patients undergoing stageII( closure operation had significantly higher BMI [(18.4±2.0) kg/m, t=-2.747, P=0.013] and higher serum albumin [(40.8±3.6) g/L, t=-3.505, P=0.002]. Average interval between stageI( ileostomy and stageII( closure surgery was (197±77) days. Resected intestinal length of stageI( ileostomy was which was significantly longer than that of stageII( closure surgery [(74.0±56.1) cm vs. (15.5±10.4) cm, t=4.547, P= 0.000]. Abdominal adhesion classification of stageII( ileostomy plus closure operation was significantly better as compared to stage I( ileostomy(Z=-3.347, P=0.001). Morbidity of postoperative complications in stageI( ileostomy was 52.4% (11/21), which decreased to 19.0% (4/21) in stageII( operation with significant difference (χ²=5.081, P=0.024). Postoperative complication Clavien-Dindo classification and CCI scores in stageII( operation were significantly lower than those in stageI( operation (P=0.006 and P=0.002). Till June 2017, 17 of 21 patients(81.0%) were followed-up for (28±18) months. Except for 2 cases of relapse, 15 patients recovered to normal diet.</p><p><b>CONCLUSIONS</b>Application of staged ileostomy and closure operation combined with nutritional support therapy to CRII is in accordance with the principle of injury control surgery. Furthermore, this staged approach is safe and effective, can reduce the morbidity and the severity of complications, and can also be helpful to decide the margin for intestinal resection.</p>

ABSTRACT

The gut microbiota is mainly composed of a diverse population of commensal bacterial species and plays a pivotal role in the maintenance of intestinal homeostasis, immune modulation and metabolism. The influence of the gut microbiota on solid organ transplantation has recently been recognized. In fact, several studies indicated that acute and chronic allograft rejection in small bowel transplantation (SBT) is closely associated with the alterations in microbial patterns in the gut. In this review, we focused on the recent findings regarding alterations in the microbiota following SBTand the potential roles of these alterations in the development of acute and chronic allograft rejection. We also reviewed important advances with respect to the interplays between the microbiota and host immune systems in SBT. Furthermore, we explored the potential of the gut microbiota as a microbial marker and/or therapeutic target for the predication and intervention of allograft rejection and chronic dysfunction. Given that current research on the gut microbiota has become increasingly sophisticated and comprehensive, large cohort studies employing metagenomic analysis and multivariate linkage should be designed for the characterization of host-microbe interaction and causality between microbiota alterations and clinical outcomes in SBT. The findings are expected to provide valuable insights into the role of gut microbiota in the development of allograft rejection and other transplant-related complications and introduce novel therapeutic targets and treatment approaches in clinical practice.

ABSTRACT

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.

ABSTRACT

BACKGROUND/AIMS: Chronic intestinal pseudo-obstruction (CIPO) is a serious, life-threatening motility disorder that is often related to bacterial overgrowth. Fecal microbiota transplantation (FMT) results in restoration of the normal intestinal microbial community structure. We investigated the efficacy of FMT in the treatment of CIPO patients. METHODS: Nine patients (age 18–53 years) with CIPO were enrolled in this prospective, open-label study. Patients received FMT for 6 consecutive days through nasojejunal (NJ) tubes and were followed up for 8 weeks after treatment. We evaluated the rate of clinical improvement and remission, feeding tolerance of enteral nutrition, and CT imaging scores of intestinal obstructions. Lactulose hydrogen breath tests were performed before FMT and 8 weeks after FMT to evaluate for the presence small intestinal bacterial overgrowth (SIBO). RESULTS: FMT significantly alleviated bloating symptoms, and symptoms of pain were relieved 2 weeks after FMT. Enteral nutrition administered through a NJ tube after FMT was well-tolerated by 66.7% (6/9) of patients. CT scores of intestinal obstructions were significantly reduced after FMT (P = 0.014). SIBO was eliminated in 71.0% (5/7) of patients. CONCLUSIONS: This pilot study demonstrated the safety of using FMT. FMT may relieve symptoms in selected patients with CIPO. FMT may also improve patient tolerance of enteral nutrition delivered via a NJ tube.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the diagnostic value of preoperative CT enterography (CTE) on obstruction, fistula and abscess formation compared to intraoperative findings in patients undergoing surgery for Crohn's disease(CD), aiming to provide reference to clinical practice.</p><p><b>METHODS</b>Preoperative CTE data of 176 CD patients confirmed by clinic, endoscopy, imaging, operation and pathology at the Department of General Surgery in Nanjing Jinling Hospital from January 2013 to December 2015 were enrolled in retrospective cohort study. All the patients underwent enhanced full abdominal CT scan using SIMENS SOMATOM Definition Flash 64 row dual-source CT machine. CTE scans were performed from the dome of diaphragm to the symphysis pubis. The CT images in arterial and venous phase were reconstructed with 1.0 mm thin layer, and then processed in MMWP 4.0 workstation including multi-planar recombination, surface recombination and maximum density projection. The sensitivity, specificity, positive and negative predictive value, false negative rate and accuracy of preoperative CTE on obstruction, fistula and abscess were compared with intraoperative findings.</p><p><b>RESULTS</b>Among 176 patients, 122 were males and 54 were females with median age of 29 (18 to 65) years, median disease duration of 48 (1 to 240) months, median time interval from CT scan to operation of 16(1 to 30) days, and median body mass index of 17.8 (10.8 to 34.7) kg/m. Twenty-six cases (14.8%) had nutritional risk (NRS2002≥3); 23 cases (13.1%) had lesions limited to ileum; 19 cases (10.8%) had lesions limited to colon; 126 cases (71.6%) had simultaneous lesions of ileum and colon, and 8 cases (4.5%) had lesion in upper gastrointestinal tract. A total of 199 lesions of small intestine were identified by preoperative CTE, including 131 of obstruction (65.8%), 42 of fistula (21.1%), and 26 of abscess (13.1%), while 235 lesions were confirmed by operation, including 133 of obstruction (56.6%), 74 of fistula (31.5%), 28 of abscess (11.9%). The modification of planned surgical procedure due to unexpected intraoperative findings were found in 29(16.5%) patients. The sensitivity, specificity, positive predictive value and negative predictive value of preoperative CTE were 86.4%, 78.8%, 86.9% and 76.0% for obstruction; 83.8%, 79.1%, 67.5% and 90.4% for fistula; and 96.2%, 98.0%, 90.1% and 99.3 for abscess, respectively.</p><p><b>CONCLUSION</b>Preoperative CTE can effectively evaluate the lesions of intestinal obstruction, fistula and abscess in CD patients, with the highest accuracy of abscess, and has quite good consistency with intraoperative findings, which may be used as the first choice of imaging diagnosis of CD.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the efficacy of over-the-scope clip (OTSC) in the treatment of gastrointestinal fistula.</p><p><b>METHODS</b>Clinical data of 12 gastrointestinal fistula patients, including 3 internal fistula and 9 external fistula treated with OTSC in our institute from March 2015 to May 2016 were retrospectively analyzed. OTSC was performed when pus was drained thoroughly and intra-abdominal infection around gastrointestinal fistula was controlled, and each patient received one clip to close fistula.</p><p><b>RESULTS</b>There were 6 female and 6 male patients with mean age of (50.1±12.6) years. The successful rate of endoscopic closure was 100% without complications including bleeding and intestinal obstruction during and after OTSC treatment. According to comprehensive evaluation, including drainage without digestive juices, no recurrence of intra-abdominal infection, no overflow of contrast medium during digestive tract radiography, and CT examination without intra-abdominal abscess, clinical gastrointestinal fistula closure was 91.7%(11/12). There was no recurrence of gastrointestinal fistula during 3 months of follow-up in 11 patients. In the remaining 1 case, the gastric fistula after laparoscopic sleeve gastrectomy recurred one week after OTSC treatment because of intra-abdominal infection surrounding fistula, and was cured by surgery finally.</p><p><b>CONCLUSION</b>The endoscopic closure treatment of OTSC for gastrointestinal fistula is successful and effective, and control of intra-abdominal infection around fistula with adequate drainage is the key point.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effect of a clinical pathway for Crohn disease (CD) complicated with intestinal obstruction.</p><p><b>METHODS</b>CD patients complicated with intestinal obstruction in Inflammatory Bowel Disease(IBD) Center of Jinling Hospital were enrolled. One hundred and nineteen CD patients from March 2014 to September 2015 received treatment with the clinical pathway (CP), which was developed based on medical evidence and experience of the IBD center in February 2014, as CP group. The other 108 CD patients from September 2012 to February 2014 received treatment according to the management strategy made by individual attending physician as non-CP group. Rate of operation, rate of stoma, morbidity of surgical complications, hospital stay, hospital cost, and 6-month unplanned re-admission were compared between two groups.</p><p><b>RESULTS</b>The baseline data were similar between the two group (all P > 0.05). No significant differences were noted between these the two groups in terms of rate of operation (73.9% vs. 77.8%, P = 0.605), rate of stoma (15.9% vs. 25.0%, P = 0.197), and morbidity of surgical complications (23.9% vs. 27.4%, P = 0.724). However, the mean postoperative hospital stay was shorter (10.9 d vs. 13.2 d, P = 0.000), the mean hospital cost was less (78 325 Yuan vs. 85 310 Yuan, P = 0.031) and the rate of 6-month unplanned re-admission was lower(3.4% vs. 11.1%, P = 0.035) in CP group.</p><p><b>CONCLUSION</b>Treatment based on this CP for CD patients complicated with intestinal obstruction can reduce the rate of 6-month unplanned re-admission, shorten the postoperative hospital stay and decrease the hospital cost in patients requiring surgery.</p>

ABSTRACT

Objective Acute pancreatitis exhibits different clinical and ultrasonic features in patients complicated with acute acalculous cholecystitis ( AAC) at different stages .The aim of this study was to analyze the ultrasonic characteristics of acute pancreati-tis complicated with AAC at different stages . Methods We retrospectively analyzed the clinical data about 41 cases of acute pancrea-titis with moderate to severe AAC .According to whether AAC developed within or after 2 weeks of the onset of acute pancreatitis , we divided the patients into an early-stage group (n=18) and a late-stage group (n=23).We recorded the gallbladder size, gallbladder wall thickness , fluid around the gallbladder , biliary sludge deposition and the Murphy′s sign by ultrasonography , obtained AAC-related clinical and laboratory data concerning body temperature , Murphy′s sign, WBC count and C-reactive protein level , and analyzed the ultrasonic features of AAC at different stages in the acute pancreatitis patients. Results All the patients experienced a fever of >38.5℃, 38.89%with chills in the early onset group and 47.83%in the late onset group .Increases were observed in patients of the early-and late-stage groups in the WBC count ( 94.44%vs 82.61%) , the C-reactive protein level ( 100%vs 91.30%) , and the fluid volume around the gallbladder (94.44%vs 60.86%, P<0.05), but incidence rate of gallbladder wall thickening was significantly lower in the former than in the latter group (11.11%vs 78.26%, P<0.01). Conclusion AAC developing at different stages of acute pancreatitis has different ultrasonic features , with higher incidence rates of fluid around the gallbladder in the early stage and gallbladder wall thickening in the late stage.

ABSTRACT

Objective:To investigate the dynamic changes of the luminal microbiota in the jejunum following administration of proton pump inhibitors (PPIs) in a rat model.Methods:Rats were randomized into six groups (n =6 each group).A group of rats were sacrificed just after anesthesia as normal control (0 d) and,other five groups were continuously administered with omeprazole (10 mg/kg twice daily,intraperitoneally) and were euthanized at 5,9,14,21,28 days following the treatment,respectively.Total DNA in the luminal contents of jejunum was extracted and was used for polymerase chain reaction (PCR) amplification with the primer set targeted the hypervariable V3 region of 16S ribosomal RNA genes.Subsequently,the amplicons were separated by denaturing gradient gel electrophoresis (DGGE).After the gels were stained and photographed,the bands were cut out and sequenced to determine the closest bacterial relatives with the BLAST.The DGGE profiles were analyzed to evaluate the shifts of the microbiota composition and diversity following treatments.Results:Changes of the jejunal microbiotas in rats were observed at 5 and 9 days post PPI administration,as characterized by outgrowth of Streptococcus pneumonia,Clostridium saccharolyticum and Lactococcus garvieae compared to those of the controls (0 d).With time extension of PPI treatment,the mictobiotas significantly shifted toward dysbiotic state,in which the opportunistic pathogens,including Ertterococcus faecalis and Clostridium difficile,were strikingly expanded,especially 21 days later.However,the commensals such as Lactobacillus reuteri and Weissella koreensis were markedly declined in PPI-treated animals compared with the controls.The similarity of the jejunal microbiotas between PPI-treated animals and controls was markedly reduced following PPI treatment,reaching (56.1 ± 16.7) % at 28 days.Conclusion:Our data demonstrate that the gastric acid suppression could induce shifts of the jejuna microbiota in a rat model.More importantly,long-term use (> 14 d) of PPI could lead to the dysbiosis of the jejunal microbiota,which might be related causally to increased susceptibility to enteric infection.

ABSTRACT

Objective Up to the present time, no reports are seen at home or abroad on the clinical characteristics of severe acute pancreatitis (SAP) with persistent inflammation-immunosuppression-catabolism syndrome (PICS), and few studies have been conducted on the risk factors for PICS.This article summarizes the clinical characteristics of PICS in SAP patients and presents a multivariate regression analysis of its risk factors.Methods This is a retrospective study on the clinical data about 214 cases of SAP treated for over 14 days in the Surgical Intensive Care Unit (SICU) from January 1, 2014 to December 31, 2015.According to the diagnostic criteria of PICS, we divided the SAP patients into a PICS group (n=149) and a non-PICS group (n=65).We compared the systemic and pancreatitis-specific complications and mortality rates in the SICU and at 12 months after discharge.We also performed a multivariate regression analysis on the risk factors of PICS.Results The incidence rates of biliary SAP and multiple-organ dysfunction syndrome (MODS) were significantly higher in the PICS (44.3% and 93.3%) than in the non-PICS group (29.2% and 55.4%) (P=0.038).The results of multivariate regression analysis showed that the risk factors for PICS included obesity (OR=2.3;95% CI: 1.0-5.2), biliary causes (OR=4.2;95% CI: 1.4-13.0), and MODS (OR=4.4;95% CI: 1.3-14.4).The survival rate at 12 months after discharge was remarkably lower in the PICS than in the non-PICS group (88.5% vs 98.2%, P=0.036).Conclusion The incidence rate of PICS is high in SAP patients.Obesity, biliary causes and MODS are independent risk factors for PICS.The complication of PICS may be an important indicator of the poor prognosis of SAP.

ABSTRACT

Objective@#To study the value of three-dimensional(3D) visualization in the diagnosis and surgical treatment for pancreatic tumor.@*Methods@#From June to September 2016, 26 patients with pancreatic tumors in Jinling Hospital, Medical School of Nanjing University were involved. The study included 26 patients(8 females and 18 males) with mean age of (57±12)years (ranging from 23 to 77 years). And there were 20 malignant tumors and 6 benign tumors. All of them were examined with abdominal thin slice CT scanning and the CT images were imported into 3D visualization system for 3D visualization. The main elements examined by 3D visualization included tumor shape, size, and location; distribution and morphology of the peripancreatic lymph node; the relationships among neoplasms, organs and blood vessels.@*Results@#Among the 26 patients, there were 21 cases with pancreatic cancer, of which 15 cases successfully underwent standard pancreatectomy. All patients were operated underwent accurate assessment. The 3D model demonstrated the origination and bifurcations of blood vessels, and the relationships among neoplasms, organs and blood vessels efficiently. The 3D technique could facilitate to evaluate response of neiadjuvant chemotherapy in the pancreatic cancer patients (n=5).3D reconstruction could detect the lymph-node metastases accurately (n=12) in patients with pancreatic cancer. 3D reconstruction were applied to evaluate the the size and range of tumor on 5 cases.@*Conclusions@#3D reconstruction allows stereoscopic identification of the spatial relationships between physiologic and pathologic structures.The 3D technique could facilitate to evaluate distribution and morphology of the peripancreatic lymph node, and to evaluate the relationships among neoplasms, organs and blood vessels.
