ABSTRACT

Objective:To investigate the clinical efficacy of pancreaticoduodenectomy (PD) for periampullary diseases.Methods:The retrospective cohort study was conducted. The clinico-pathological data of 2 019 patients with periampullary diseases who underwent PD in the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2020 were collected. There were 1 193 males and 826 females, aged 63(15) years. Observation indicators: (1) surgical situations; (2) postoperative conditions; (3) postoperative pathological examinations; (4) prognosis of patients with periampullary carcinoma. Regular follow-up was conducted by telephone interview and outpatient examination once every 3 months within the postoperative first year and once every 6 months thereafter to detect the survival of patients with periampullary carcinoma. The follow-up was up to December 2021. Measurement data with skewed distribution were represented as M(IQR) or M(range), and comparison between groups was analyzed using the rank sum test. Count data were described as absolute numbers and (or) percentages, and comparison between groups was analyzed by the chi-square test or Fisher exact probability. Kaplan-Meier method was used to draw survival curves and calculate survival rates, and Log-Rank test was used to conduct survival analysis. Results:(1) Surgical situations: of 2 019 patients, 1 116 cases were admitted from 2016-2018 and 903 cases were admitted from 2019-2020. There were 1 866 cases undergoing open PD and 153 cases undergoing laparoscopic or robot-assisted PD. There were 1 049 cases under-going standard PD and 970 cases undergoing pylorus-preserved PD. There were 215 cases combined with portal mesenteric vein resection, 3 cases combined with arterial resection. The operation time of 2 019 patients was 255(104)minutes and the volume of intraoperative blood loss was 250(200)mL. The intraoperative blood transfusion rate was 31.401%(623/1 984), with the blood transfusion data of 35 cases missing. The proportions of pylorus-preservation, combination with portal mesenteric vein resection, intraoperative blood transfusion were 585 cases(52.419%), 97cases(8.692%), 384 cases(34.941%) for patients admitted in 2016-2018, versus 385 cases(42.636%), 118 cases(13.068%), 239 cases(27.006%) for patients admitted in 2019-2020, showing significant differences between them ( χ2=19.14,10.05,14.33, P<0.05). (2) Postoperative conditions: the duration of postoperative hospital stay of 2 019 patients was 13 (10) days. One of 2 019 patients lacked the data of postopera-tive complications. The overall postoperative complication rate was 45.292%(914/2 018), of which the incidence rate of grade B or C pancreatic fistula was 23.439%(473/2 018), the rate of grade B or C hemorrhage was 8.127%(164/2 018), the rate of grade B or C delayed gastric emptying was 15.312%(309/2 018), the rate of biliary fistula was 2.428%(49/2 018) and the rate of abdominal infection was 12.884%(260/2 018). The reoperation rate of 2 019 patients was 1.932%(39/2 019), the in-hospital mortality was 0.644%(13/2 019), the postoperative 30-day mortality was 1.238%(25/2 019), and the postoperative 90-day mortality was 2.675%(54/2 019). There were 541 cases(48.477%) with overall postoperative complications, 109 cases(9.767%) with grade B or C hemorr-hage, 208 cases(18.638%) with grade B or C delayed gastric emptying , 172 cases(15.412%) with abdominal infection, 39 cases(3.495%) with postoperative 90-day mortality of 1 116 patients admitted in 2016-2018. The above indicators were 373 cases(41.353%), 55 cases(6.098%), 101 cases(11.197%), 88 cases(9.756%), 15 cases(1.661%) of 902 patients admitted in 2019-2020, respectively. There were significant differences in the above indicators between them( χ2=10.22, 9.00, 21.30, 14.22, 6.45 , P<0.05). The in-hospital mortality occurred to 11 patients(0.986%) of 1 116 patients admitted in 2016-2018 and to 2 cases(0.221%) of 903 patients admitted in 2019-2020, showing a significant difference between them ( P<0.05).

The histological types of 411 patients with benign or low poten-tial malignancy included intraductal papillary mucinous neoplasm in 107 cases (26.034%), chronic or autoimmune inflammatory disease in 62 cases(15.085%), neuroendocrine tumor in 58 cases(14.112%), pancreatic serous cystadenoma in 52 cases(12.652%), pancreatic solid pseudopapillary tumor in 36 cases(8.759%), gastrointestinal stromal tumor in 29 cases(7.056%), villous ductal adenoma in 20 cases(4.866%), pancreatic mucinous cystadenoma in 2 cases(0.487%), pancreatic or duodenal trauma in 2 cases(0.487%) and other histological types in 43 cases(10.462%). (4) Prognosis of patients with periampullary carcinoma. Results of survival analysis of 1 590 patients with main locations of periampullary carcinoma showed that of 1 023 patients with pancreatic cancer, 969 cases were followed up for 3.0-69.6 months, with a median follow-up time of 30.9 months. The median overall survival time, 1-year, 3-year and 5-year survival rates of pancreatic cancer patients were 19.5 months [95% confidence interval ( CI) as 18.0-21.2 months], 74.28%, 29.22% and 17.92%. Of 225 patients with duodenal papillary cancer, 185 cases were followed up for 3.0-68.9 months, with a median follow-up time of 36.7 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were unreached, 94.92%, 78.87% and 66.94%. Of 156 patients with distal bile duct cancer, 110 cases were followed up for 3.0-69.5 months, with a median follow-up time of 25.9 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were 50.6 months (95% CI as 31.4 to not reached), 90.37%, 56.11% and 48.84%. Of 134 patients with ampullary cancer, 100 cases were followed up for 3.0-67.8 months, with a median follow-up time of 28.1 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were 62.4 months (95% CI as 37.8 months to not reached), 90.57%, 64.98% and 62.22%. Of 52 patients with duodenal cancer, 38 cases were followed up for 3.0-69.5 months, with a median follow-up time of 26.2 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were 52.0 months (95% CI as 30.6 months to not reached), 93.75%, 62.24% and 40.01%.There was a significant difference in overall survival after PD between patients with different locations of periampullary malignancies ( χ2=163.76, P<0.05). Conclusions:PD is safe and feasible in a high-volume pancreas center, but the incidence of overall postoperative complications remains high. With the increase of PD volume, the incidence of overall postoperative complications has significantly decreased. There is a significant difference in overall survival time after PD among patients with different locations of periampullary malignancies. The 5-year survival rate after PD for duodenal papillary cancer, ampullary cancer, duodenal cancer and distal bile duct cancer is relatively high, whereas for pancreatic cancer is low.

ABSTRACT

Objective:To investigate the current situation with regard to a sense of coherence in major caregivers of enterostomy patients and analyze its relationship with self-efficacy and perceived social support.Methods:From July to December 2019, a total of 118 major caregivers of enterostomy patients were investigated using a general information questionnaire, a self-efficacy scale, and a perceived social support scale.Results:The score of sense of coherence in major caregivers of enterostomy patients was 58.40±9.17, and the average scores of all dimensions, from high to low, were “controllable sense,” “understandable sense,”and “meaningful sense.” Sense of coherence was positively correlated with self-efficacy and perceived social support ( r=0.457, P<0.01; r=0.369, P<0.01). Hierarchical multiple regression analysis showed that self-efficacy and perceived social support had a positive predictive effect on sense of coherence and explained 35.2% of the variance ( R′ 2=0.352, F=25.639, P<0.001). Conclusions:The main caregivers of enterostomy patients had a low level of sense of coherence. Self-efficacy and perceived social support have a positive effect on sense of coherence. Medical staff should take targeted measures to help caregivers improve their self-efficacy and social support system in order to improve their sense of coherence.

ABSTRACT

Objective:To investigate the application value of TRIANGLE operation in radical resection of pancreatic cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 30 patients with pancreatic cancer who underwent TRIANGLE operation in the First Affiliated Hospital of Nanjing Medical University from March 2020 to July 2020 were collected. There were 18 females and 12 males, aged from 41 to 79 years, with a median age of 65 years. After assessment of the resectability and dissection of the hepatoduodenal ligament, the superior mesenteric artery, celiac axis, common hepatic artery, portal vein and superior mesenteric vein of patients were exposed. According to the location of tumor, patients were performed pancreaticoduodenectomy, distal pancreatectomy or total pancreatectomy combined with dissection of putatively tumor-infiltrated lymphatic and neural tissue from the triangular space. During the TRIANGLE operation, it required to at least finish the skeletonization of right semi-circumference of the superior mesenteric artery and celiac axis in cases of pancreatico-duodenectomy, whereas the left semi-circumference in cases of distal pancreatectomy. In principle, both of the superior mesenteric artery and celiac axis were circumferentially skeletonized for cases of total pancreatectomy. Lymphatic, neural and fibrous tissues between the superior mesenteric artery and the celiac artery were completely dissected in all patients. Observation indicators: (1) surgical conditions and postoperative histopathological examination; (2) postoperative recovery situations; (3) follow-up. Regular follow-up was conducted by telephone interview or outpatient examinations to understand tumor recurrence and metastasis of patients up to January 2021. Measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages, Fisher exact probability method was used for comparison between groups. Results:(1) Surgical conditions and postoperative histopathological examination: all patients underwent open operation, including 21 cases of pancreaticoduodenec-tomy, 6 cases of distal pancreatectomy, 2 cases of total pancreatectomy, 1 case of mid-segment preserving pancreatectomy. There were 16 cases combined with portal vein-superior mesenteric vein resection and 3 cases combined with left adrenal resection. For the dissection area of superior mesenteric artery-celiac axis, one cycle was conducted in 5 of 30 patients, one and a quarter cycle in 8 patients, one and a half cycle in 8 patients, one and three quarters?two cycles in 9 patients. There were 16 cases with left gastric vein dissection and 14 cases with left gastric vein preservation. The operative time of 30 patients was 287 minutes (range, 165?495 minutes) and the volume of intraoperative blood loss was 275 mL(range, 50?800 mL). Nine patients received intraoperative transfusion of red blood cells or frozen plasma. Postoperative histopathological examination showed that the tumor diameter was 3.4 cm (range, 1.2?7.3 cm), the number of harvested lymph nodes was 20 (range, 9?35), the number of positive lymph nodes was 2 (0?19). Of the 30 patients,20 cases had moderately differentiated tumor and 10 cases had poorly differentiated tumor. R 0 resection was achieved in 9 patients, 1 mm R 1 resection in 17 patients, and R 1 resection in 4 patients. Postoperative pathological T stages: 3 of 30 patents were in stage T1, 18 cases were in stage T2, 5 cases were in stage T3, and 4 cases were in stage T4. Postoperative pathological N stages: 9 of 30 patents were in stage N0, 13 cases were in stage N1, and 8 cases were in stage N2. Postoperative pathological TNM stages: 2 of 30 patents were in stage Ⅰa, 2 cases were in stage Ⅰb, 3 case were in stage Ⅱa, 11 cases were in stage Ⅱb, 12 cases were in stage Ⅲ. (2) Postoperative recovery situations: 20 of 30 patients had postoperative complications, including 6 cases of Clavien-Dindo grade I complications, 9 cases of grade Ⅱ complications, 3 cases of grade Ⅲa complications, 2 cases of grade V complications. The incidence of postoperative diarrhea was 0 in cases with one cycle dissection of tissues around superior mesenteric artery-celiac axis, 1/8 in cases with one and a quarter cycle dissection, 4/8 in cases with one and a half cycle dissection, 9/9 in cases in with one and three quarters-two cycles dissection, showing a significant difference between the four groups ( P<0.05). The incidence of delayed gastric emptying was 5/16 in patients with left gastric vein dissection, versus 1/14 in patients with left gastric vein preservation, showing no significant difference between the two groups ( P>0.05). Nineteen of 30 patients received adjuvant chemotherapy.Twenty-eight of 30 patients were successfully discharged from hospital, with the duration of postoperative hospital stay of 15 days(range, 8?68 days) and the rest of 2 patients died. Three patients had unplanned readmission within postoperative 90 days. (3) Follow-up: all the 28 patients discharged from hospital were followed up for 1.0?9.0 months, with the median follow-up time of 6.5 months. During the follow-up, one patient with locally advanced pancreatic cancer had local recurrence, 9 patients had liver metastasis (including 4 cases with resectable pancreatic cancer, 4 cases with borderline resectable pancreatic cancer, 1 case with borderline resectable pancreatic cancer), and 1 patient with borderline resectable pancreatic cancer had peritoneal metastasis. The rest of 17 patients survived without tumor recurrence. Conclusions:TRIANGLE operation in the radical resection of pancreatic cancer has high radicality and low postoperative local recurrence, but a slightly high morbidity and mortality rate. Its long-term efficacy needs to be further evaluated. It is recommend that this procedure should be performed for selected patients after neoadjuvant chemotherapy in high-volume pancreatic surgery centers.

ABSTRACT

Objective:To explore benefit finding and its influencing factors among enterostomy patients.Methods:A total of 120 enterostomy patients were investigated with general information questionnaire, Benefit Finding Scale, Simplified Scale of Resilience and Perceived Social Support Scale.Results:The score of benefit finding among enterostomy patients was 49.44±5.86. Multiple regression analysis showed that education level, self-care, complications, resilience, perceived social support were influencing factors of benefit finding, and explained 51.1% of the variance.Conclusions:The benefit finding among enterostomy patients was grim. It is suggested that clinical staff pay more attention to the patients with low education, poor self-care and complications of stoma, and also pay more attention to the positive psychology and the social support system of patients, guide patients to pay attention to the positive significance of the disease, so as to improve the level of benefit finding.

ABSTRACT

Objective@#To evaluate risk factors for delayed gastric emptying(DGE)following pancreaticoduodenectomy(PD).@*Methods@#There were 492 consecutive patients who underwent PD in Pancreas Center, the First Affiliated Hospital with Nanjing Medical University between January 2012 and December 2014 were identified from a prospective database.There were 315 male and 177 female patients with a median age of 60.5 years.Univariate and multivariate analyses were performed to investigate the independent risk factors for clinically relevant DGE(CR-DGE).@*Results@#The overall incidence of DGE was 29.5%, with Grade B and C occurring at 4.3% and 5.9%, respectively.In multivariate analysis, pancreatic duct diameter less than 3 mm(OR=1.888, P=0.042), pylorus-preserving pancreaticoduodenectomy(OR=2.627, P=0.005) and clinically relevant postoperative pancreatic fistula(OR=2.740, P=0.007) were independently associated with CR-DGE.Other main complications such as postoperative pancreatic fistula, pyoperitoneum, intraabdominal infection were also associated with the severity of DGE(χ2=21.360, 14.422, 14.378; P=0.011, 0.002, 0.002). DGE patients had a significantly prolonged postoperative length of stay(31(24-41)d vs. 13(11-17)d) and increased medical cost((122 367.5±66 068.3)yuan vs. (78 200.7±27 043.9)yuan)(both P<0.01).@*Conclusions@#Small pancreatic duct, underwent pylorus-preserving pancreaticoduodenectomy and suffered postoperative pancreatic fistula might indicate a high risk of CR-DGE.

ABSTRACT

Objective@#To explore the clinical effect of a novel artery first and uncinate process first approach for laparoscopic pancreaticoduodenectomy(LPD), emphasizing the left lateral and posterior dissection of uncinate process (UP) via Treitz ligament approach.@*Methods@#From April to November 2016, 18 patients received LPD with a novel approach in Pancreas Center of the First Affiliated Hospital with Nanjing Medical University. All patients were diagnosed as pancreatic head or peri-ampulla tumor, without major vessel invasion nor distant metastasis. For resection, routine caudal view was used in the first step, to dissect the anterior medial border between uncinate process and superior mesenteric vein(SMV). Lymphatic tissues were completely dissected form anterior surface of hepatoduodenal ligament. In the second step, left lateral view with camera from left para-umbilical trocar was used, Treitz ligament was incised, SMA root was exposed. After anticlockwise rotation and retraction of mesentery, the anatomic relationship between SMA trunk, inferior pancreaticoduodenal artery(IPDA), jejunal branch of SMV, and distal part of UP, could be perfectly exposed from left lateral view. SMA was dissected from its root until the position above the uncinate process and duodenum, IPDA was transected, distal part of UP was freed from SMA. In the third step, right lateral view and caudal view were alternatively used; proximal UP mesentery was completely dissected out from SMA root, CA root and posterior surface of hepatoduodenal ligament. Pancreaticoduodenectomy was completed in the forth step after transection of pancreatic neck and common hepatic duct.@*Results@#The SMA root and distal UP were successfully dissected out via Treitz ligament approach in all 18 patients, among them, distal UP was completely excised in 8 patients from left view. Postoperative pathology showed R0 resection rate in 69%. Postoperative complication included intra-abdominal hemorrhage in 1 patient, pancreatic fistula in 7 patients(6 cases with grade A and 1 case with grade B), delayed gastric emptying in 4 patients (2 cases with grade A, 2 cases with grade B). Average postoperative hospital stay was (15.5±6.8)days.@*Conclusion@#The novel artery first and uncinate process first approach through Treitz ligament could help surgeons to completely dissect the full length of meso-pancreas along celiac axis-SMA axis in LPD.

ABSTRACT

Objective:To investigate the expression levels of CXCR1,CXCR2 and their common ligand CXCL8 in peripheral blood mononuclear cells (PBMCs) and liver biopsy from the patients with hepatitis B related hepatocellular carcinoma and their clinical significances.Methods:Quantitative real time polymerase chain reaction (qRT-PCR) was used to detect the mRNA levels of CXCR1,CXCR2,CXCL8 in the peripheral blood mononuclear cells of thirty-six hepatitis B related hepatocellular carcinoma and the protein levels of CXCR1 and CXCR2 and CXCL8 in liver biopsy were detected by SP immunohistochemical method.The level of C-reactive protein in serum was determined by chemiluminescence immunoassay respectively.Then,the correlations between CRP and the mRNA of CXCR1,CXCR2 and CXCL8 were analyzed.Results:The mRNA levels of CXCR1 (0.952 7±0.197 2),CXCR2 (0.896 9±0.173 0),CXCL8 (1.771 9±0.248 9) in the PBMCs of hepatitis B related hepatocellular carcinoma were significantly higher than those in controls (P<0.01).And the protein levels of CXCR1,CXCR2 and CXCL8 were also obviously increased in liver biopsy of hepatitis B related hepatocellular carcinoma (P<0.05).In addition,there was positive correlations between the level of serum C-reactive protein and the mRNA expression of CXCR1 (r =0.54,P<0.01),CXCR2 (r =0.49,P<0.01),CXCL8 (r =0.63,P<0.01).Conclusion:The levels of CXCR1,CXCR2 and CXCL8 significantly increased in hepatitis B related hepatocellular carcinoma patients and positively correlated with serum CRP,suggesting that CXCR1,CXCR2 and their common ligand CXCL8 signal transduction process may play a key role in the pathological process of hepatitis B related hepatocellular carcinoma,which may provide a new direction for the immune intervention therapy of hepatocellular carcinoma.

ABSTRACT

BACKGROUND: At present, most of the literature on joint replacement focus on the causes and countermeasures of long-term complications, but seldom focuses on causes of postoperative short-term complications, such as wound exudation and delayed union. Whether the incidence of sustained exudation and delayed wound healing in patients with hypertension after hip replacement is higher than that in patients with normal blood pressure is not reported at present.OBJECTIVE: To identify the correlation of hypertension with persistent wound exudation and delayed wound healing in patients after femoral head replacement.METHODS: Data of 205 elderly patients with femoral neck fractures were retrospectively analyzed. All patients underwent femoral head replacement. In accordance with the hypertension diagnostic criteria of 2010 Chinese Guidelines for the Management of Hypertension, patients were divided into hypertension group and control group.Intraoperative blood loss, postoperative blood loss, the days of prolonged wound exudation, the wound dehiscence, and the prevalence of delayed wound healing were compared between the two groups. Then, we analyzed the relationship of hypertension with wound exudation and delayed wound healing.RESULTS AND CONCLUSION: (1) The average systolic blood pressures were 153.55 mmHg and 128.82 mmHg in the hypertension and control groups, respectively (P 0.05). (3) The time of persistent wound exudation was 4.03 days and 2.08 days in the hypertension group and control group, respectively (P < 0.05). (4) The prevalence of delayed wound healing was significantly higher in the hypertension group than that in the control group (P < 0.05). (5) Hypertensive patients had a higher risk of prolonged wound exudation and delayed healing than their normotensive counterparts, and the hypertension is one of the important influence factors for delayed wound healing.

Objective To investigate the expression and clinical significance of CXC chemokine receptors 1 and 2 (CXCR1 and CXCR2) and CXCL8 in peripheral blood mononuclear cells (PBMCs) and liver biopsy tissues from patients with primary hepatocellular carcinoma (PHC).Methods Serum specimens were collected from 36 patients with PHC, 30 patients with liver cirrhosis and 28 healthy subjects.Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to measure the expression of CXCR1, CXCR2 and CXCL8 at mRNA level in PBMCs.Streptavidin-perosidase (SP) immunohistochemistry was used to detect the expression of CXCR1, CXCR2 and CXCL8 at protein level in liver biopsy tissues.Levels of C-reactive protein (CRP), alpha-fetoprotein (AFP) and ferritin (FER) in the serum specimens were detected by chemiluminescence immunoassay.Then the correlations between these markers were analyzed.Results All of the results showed that the expression of CXCR1, CXCR2 and CXCL8 at mRNA level in PBMCs from the PHC group were higher than those of the healthy control group (P<0.01) as well as those of the liver cirrhosis group (P<0.05).Up-regulated expression of CXCR1, CXCR2 and CXCL8 in patients with PHC were associated with the depth of tumor invasion, lymph node or distant metastasis, clinical stage and levels of CRP, AFP and FER in serum (P<0.05).The expression of CXCR1, CXCR2 and CXCL8 at protein level in liver biopsy tissues were also significantly increased in the PHC group in comparison with those of the healthy control group as indicated by the result of SP immunohistochemistry (P<0.05).Conclusion Levels of CXCR1, CXCR2 and CXCL8 in the patients with PHC are significantly increased and positively correlated with the levels of AFP, FER and CRP in serum, suggesting that the signal transduction process mediated by CXCR1, CXCR2 and their common ligand CXCL8 may play a key role in the pathological process of PHC.This study may provide a potential new strategy for immune intervention in hepatocellular cancer.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of initiative and passive perioperative function exercises on hidden blood loss (HBL).</p><p><b>METHODS</b>Two hundreds and thirty elderly patients with hip fractures aging from 67 to 87 years (average age of 73.6 years) who underwent total hip replacement were included. By the intensity and the manner of perioperative function exercises, patients were divided into four groups: little initiative function exercises group (group A, n=51), little initiative and passive function exercises group (group B, n=54), normal initiative function exercises group (group C, n=65), normal initiative and passive function exercises group (group D, n=60). The true total blood loss, HBL and their proportion on the original blood volume and total blood loss was calculated depending on height, weight, intra-operative blood loss, post-operative blood loss, pre- and post-operative hematocrit, and blood transfused. According to the proportion of mean HBL on total blood loss, patients were divided into low HBL group and high HBL group. The data were analyzed by t test.</p><p><b>RESULTS</b>The mean HBL was 517 ml, 41.9% of the total blood loss. Thereinto, the mean HBL was 695 ml in group A, 49.3% of the total blood loss, the prevalence of high HBL was 66.7% (34/51); the mean HBL was 625 ml in group B, 46.9% of the total blood loss, the prevalence of high HBL was 59.3% (32/54); the mean HBL was 446 ml in group C, 38.4% of the total blood loss, the prevalence of high HBL was 30.8% (20/65); the mean HBL was 346 ml in group D, 32.3% of the total blood loss, the prevalence of high HBL was 20.0% (12/60). Mean HBL, mean HBL/total blood loss, prevalence of high HBL were lower in group C than that in group A and group B (all P<0.05); and were lower in group D than that in group C (all P<0.05). The prevalence was 57.4% (132 cases) in low HBL group, and 42.6% (98 cases) in high HBL. The proportion of little initiative function exercises patients in high HBL group was obviously higher than that in low HBL group (P<0.05).</p><p><b>CONCLUSIONS</b>The intensity and the manner of perioperative function exercises are strongly associated with the HBL in elderly patients with total hip replacement. The initiative combined with the passive function exercises could be effectively prevent and reduce the incidence of high HBL.</p>

ABSTRACT

Pancreatic neuroendocrine neoplasmas (PNENs) are classified into functioning & non-functioning tumors. The radical surgery is the only effective way for the cure & long-term survival. For the locoregional resectable tumors, the surgical resection is the first choice of treatment; the surgical procedures include local resection (enucleation) and standard resection. For the insulinomas and non-functioning tumors less than 2 cm, local resection (enucleation),distal pancreatectomy with spleen-preservation or segmental pancreatectomy are the commonly selected procedures. The radical resections with regional lymph nodes dissection, including pancreaticoduodenectomy, distal pancreatectomy and middle segmental pancreatectomy, should be applied for tumors more than 2 cm or malignant ones. For the locoregional advanced or unresectable functioning tumors, debulking surgery should be performed and more than 90% of the lesions including primary and metastatic tumors should be removed; for the non-functioning tumors, if complicated with biliary & digestive tract obstruction or hemorrhage, the primary tumors should be resected. The liver is the most frequent site of metastases for PNENs and three types of metastases are defined. For typeⅠmetastasis, patients are recommended for surgery if there are no contraindications; For type II metastasis, debulking surgery should be applied and at least 90% of metastatic lesions should be resected, and for patients with primary tumors removed and no extrahepatic metastases, or for patients with well-differentiated (G1/G2) tumors, liver transplantation may be indicated. For the unresectable type Ⅲ metastasis, multiple adjuvant therapies should be chosen.

ABSTRACT

BACKGROUND:Perioperative high hidden blood loss affects the recovery of joint function after total hip replacement. OBJECTIVE:To analyze the reliability of the Mini Nutritional Assessment on evaluating the nutritional status in elderly patients with femoral neck fracture on admission, and to investigate the effect of nutritional status variation on hidden blood loss after total hip replacement. METHODS:234 elderly patients with femoral neck fracture underwent total hip replacement. By using Mini Nutritional Assessment, patients were randomly divided into three groups:wel-nourishment group (n=52), malnourishment at risk group (n=92), and malnourishment group (n=90). The results were used to analyze the correlation of Mini Nutritional Assessment and serological nutrition indicators, and to hidden blood loss. RESULTS AND CONCLUSION:(1) Hidden blood loss:101 patients suffered from high hidden blood loss. Hidden blood loss, its proportion to total blood loss and incidence of high hidden blood loss gradual y increased with the deterioration of the nutritional status (P<0.05). (2) Mini Nutritional Assessment:Pre-operative Mini Nutritional Assessment score, and the incidence of hidden blood loss evaluated by albumin, prealbumin, transferrin, lymphocyte count, the percentage of lymphocytes and hemoglobin was significantly higher in patients with high hidden blood loss than those with low hidden blood loss (P<0.01). (3) Results of correlation analysis:High hidden blood loss was positively correlated with pre-operative Mini Nutritional Assessment, albumin, prealbumin, transferrin, the percentage of lymphocytes and hemoglobin (P<0.05). (4) These findings confirm that risk evaluation with Mini Nutritional Assessment is a reliable method to assess the nutritional status in elderly patients undergoing total hip replacement. Its combination with various serum nutrition indicators can determine high hidden blood loss and the prognosis.

ABSTRACT

BACKGROUND:The emergence of a large number of hidden blood loss during perioperative period of intertrochanteric fracture in the elderly not only increases the risk of perioperative period and complications, but also affects the postoperative recovery of joint function. At present, there is no relevant report about nutritional status and the hidden blood loss before surgery in and outside China. OBJECTIVE:To identify the effect of nutritional status on preoperative hidden blood loss in elderly patients with intertrochanteric fracture. METHODS:183 elderly patients with fresh and initial femoral intertrochanteric fracture were included. Laboratory serological examinations on admission and preoperation were completed. By mini nutritional assessment, patients were randomly divided into normal-nourishment group, malnourishment at risk group, and malnourishment group. The original blood volume and preoperative hidden blood loss were calculated depending on height, weight, hematocrit on admission and preoperation. According to the proportion of mean preoperative hidden blood loss on the original blood volume, patients were divided into low and high hidden blood loss groups. We compared preoperative hidden blood loss, and their proportion on the original blood volume and the preoperative incidence of high hidden blood loss, and analyzed the correlations between preoperative high hidden blood loss and preoperative nutritional status. RESULTS AND CONCLUSION:(1) The nutritional status of elderly intertrochanteric fracture patients measured by mini nutritional assessment score was that the number of patients was 48 cases (26%) in normal-nourishment group, 64 cases (35%) in the malnourishment at risk group, and 71 cases (39%) in the malnourishment group. There were no obvious differences in the preoperative complications between any two groups (P>0.05). (2) Thirty-eight cases affected high hidden blood loss. The mean preoperative hidden blood loss was 260.43 mL. The proportion of preoperative hidden blood loss to the original blood volume was 6%. (3) The preoperative hidden blood loss, their proportion on the original blood volume and the incidence of high hidden blood loss were significantly higher in the malnourishment at risk group and malnourishment group than in the normal-nourishment group. Paired comparison showed significant differences (P<0.05). (4) Results confirmed that preoperative hidden blood loss, their proportion on the original blood volume and the incidence of high hidden blood loss gradual y increased with deterioration of nutritional status. The nutritional status is an important factor influencing the occurrence of preoperative hidden blood loss, and can be used as an important index for judging the high hidden blood loss and prognosis in elderly patients with intertrochanteric fracture.

ABSTRACT

Objective To observe the effect of Ginkgo biloba extract (EGb) on intestinal function after spinal cord injury (SCI) in rats. Methods 36 Sprague-Dawley rats were randomly divided into group A (n=12), group B (n=12) and group C (n=12). SCI model was estab-lished with Allen's mode (10 g × 25 mm) at T10. 30 minutes later, group A was intraperitoneally injected with methylprednisolone 30 mg/kg every 24 hours;group B was injected with Shuxuening injection (EGb) 1.75 mg/kg every 24 hours;group C were injected with equal vol-ume of saline. The slow wave of intestinal smooth muscle was measured, the activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in serum were determined 1 day, 3 days and 7 days after modeling, while intestinal tissue was tested with HE stain-ing. Results The amplitude and frequency of the myoelectric slow wave increased in the groups A and B 3 and 7 days after modeling com-pared with those in the group C (P<0.05);meanwhile, the activity of SOD increased and content of MDA decreased in the groups A and B (P<0.05). The HE scores decreased in the groups A and B compared with those in the group C (P<0.05), which presented that the inflamma-tory exudation was mild, the hemorrhagic spot was few and the area was limited. The intestinal villous of the group C was blunt with large infiltration of inflammatory cells and inflammatory exudate on the mucosal surface. Conclusion EGb can improve the recovery of intestinal function in rats spinal cord injury through antioxidant.

ABSTRACT

Pancreaticoduodenectomy (PD) is the procedure for treating adenocarcinoma in periampullary region.This involves resection of multiple organs and complex reconstructions.The modern surgery has witnessed the dramatic improvement in outcomes after PD.Mortality has dropped to less than 4%,however,the complication rate remains high,making this procedure still a big challenge for most surgeons. PD is so complicated that even small mistakes could jeopardize the whole procedure and outcomes.With experiences of over 1000 PDs,we discuss the challenges of this procedure and strategies to deal with them.
