ABSTRACT

Objective:To compare the prognosis of pancreatic head cancer, uncinate process cancer and pancreatic neck cancer patients after undergoing pancreatoduodenectomy.Methods:The clinical data and follow-up data of 71 pancreatic cancer patients undergoing pancreatoduodenectomy in the First Affiliated Hospital of Xinjiang Medical University were analyzed retrospectively, Kaplan Meier method was used to compare the survival of postoperative patients. COX proportional risk model was used to analyze the survival of three groups of tumor.Results:In pancreatic cancer patients, uncinate process cancer and pancreatic neck cancer had more frequent vascular invasion, higher lymph node metastasis rate and lower R 0 resection rate than pancreatic head cancer (all P<0.05). Multivariate COX suggested that vascular invasion ( P=0.018), lymph node metastasis ( P=0.001), tumor site ( P=0.022 in uncinate process, P=0.000 in pancreatic neck) and R 0 resection ( P=0.000) were independent risk factors for prognosis. For pancreatic head cancer the 1-year recurrence rate was 43.8%, 3-year survival rate was 28.1%, median survival time was 20.0 months (95% CI 15.565-24.435). For uncinate process cancer 1-year recurrence rate was 61.5%, 3-year survival rate was 15.4%, median survival time was 14.0 months (95% CI 9.003-18.997) respectively.That was 69.2%, 7.7% and 10.0 months (95% CI 5.303-14.697) respectively for pancreatic neck cancer. Conclusion:Compared with pancreatic head cancer, uncinate process cancer and pancreatic neck cancer are associated with poorer prognosis because of frequent early vascular invasion, low R 0 resection rate and early local recurrence.

ABSTRACT

Objective To investigate the effect of open surgical drainage approach for the treatment of walled-off pancreatic necrosis ( WOPN) in severe acute pancreatitis. Methods Clinical data of 154 WOPN patients admitted in the First Affiliated Hospital of Xinjiang Medical University from January 2005 to October 2016 were retrospectively analyzed. Traditional open debridement necrosectomy was performed in 83 patients from January 2005 to October 2012 ( debridement group) , and small abdominal incision with low-position open surgical drainage was performed in 71 patients from October 2012 to October 2016 ( drainage group ) . The clinical outcomes of two groups were analyzed and compared. Results 43 cases (51. 8%) in debridement group had postoperative intraperitoneal reinfection, while there were only 13 cases with postoperative intraperitoneal reinfection (18. 3%) in drainage group;18 cases (21. 7%) in debridement group had surgery-related digestive tract fistula, while there were only 4 cases with surgery-related digestive tract fistula (5. 6%) in drainage group; the differences were statistically significant (χ2 = 18. 55, P=0. 001; χ2 = 11. 35, P=0. 002). 15 patients (18. 1%) in debridement group and only 2 patients (2. 8%) in drainage group died. The mortality in drainage group were obviously lower than that in debridement group, and the difference was statistically significant (χ2 = 9. 07, P<0. 05 ). 62 cases ( 74. 7%) in debridement group and 55 cases (77. 5%) in drainage group were cured directly, respectively. No significant difference was found between two groups. However, 3 cases (3. 6%) in debridement group and 12 cases (16. 9%) in drainage group were cured by the way of small intestinal fistula in the late stage of intubation, and the latter was higher than the former with statistically significant(χ2 =5. 989,P=0. 014). Conclusions Compared with open debridement necrosectomy, the abdominal infection rate, digestive tract fistula rate and mortality of open surgical drainage were all significantly reduced , which may be a better treatment for WOPN.

ABSTRACT

Objective To evaluate the safety and effectiveness of endovascular balloon dilatation in removing incarcerated tunnel cuffed catheter (TCC) . Methods The clinical data and the imaging materials of 4 hemodialysis patients with incarcerated TCC, who received endovascular balloon dilatation at Taizhou Hospital of Zhejiang Province, China, during the period from January 2017 to March 2018, were retrospectively analyzed. After the treatment, the patient's vital signs were monitored, and the procedure-related complications such as hemopneumothorax, subcutaneous hematoma, arrhythmia, etc. were documented. Results The mean age of the 4 patients was (73.3±6.4) years. The average indwelling time of TCC was 5.5 years (4-8 years) . Successful treatment of incarcerated TCC was achieved in all 4 patients. In one patient, both 5-mm and 6-mm balloons were used to simultaneously dilate the dual cavities of TCC.Temporary arrhythmia occurred in one patient during operation. No serious postoperative complications occurred. Conclusion For the remove of long-term indwelling incarcerated TCC, endovascular balloon dilatation is minimally-invasive, safe and effective, although more researches are needed to further confirm its safety and reliability.

ABSTRACT

Objective@#To investigate the diagnosis and treatment for enterocutaneous fistula (ECF) in China, and to explore the prognostic factors of ECF.@*Methods@#A multi-center cross-sectional study was conducted based on the Registration System of Chinese Gastrointestinal Fistula and Intra-Abdominal Infections to collect the clinical data of ECF patients from 54 medical centers in 22 provinces/municipalities from January 1, 2018 to December 31, 2018. The clinical data included patient gender, age, length of hospital stay, intensive care unit (ICU) admission, underlying diseases, primary diseases, direct causes of ECF, location and type of ECF, complications, treatment and outcomes. All medical records were carefully filled in by the attending physicians, and then re-examined by more than two specialists. The diagnosis of ECF was based on the clinical manifestations, laboratory/imaging findings and intraoperative exploration.@*Results@#A total of 1521 patients with ECF were enrolled, including 1099 males and 422 females, with a median age of 55 years. The top three primary diseases of ECF were malignant tumors in 626 cases (41.2%, including 540 gastrointestinal tumors, accounting for 86.3% of malignant tumors), gastrointestinal ulcers and perforations in 202 cases (13.3%), and trauma in 157 cases (10.3%). The direct causes of ECF were mainly surgical operation in 1194 cases (78.5%), followed by trauma in 156 (10.3%), spontaneous fistula due to Crohn′s disease in 92 (6.0%), radiation intestinal injury in 41 (2.7%), severe pancreatitis in 20 (1.3%), endoscopic treatment in 13 (0.9%) and 5 cases (0.3%) of unknown reasons. All the patients were divided into three groups: 1350 cases (88.7%) with simple ECF, 150 (9.9%) with multiple ECF, and 21 (1.4%) with combined internal fistula. Among the patients with simple ECF, 438 cases (28.8%) were jejuno-ileal fistula, 313 (20.6%) colon fistula, 170 (11.2%) rectal fistula, 111 (7.3%) duodenal fistula, 76 (5.0%) ileocecal fistula, 65 (4.3%) ileocolic anastomotic fistula, 55 (3.6%) duodenal stump fistula, 36 (2.4%) gastrointestinal anastomotic fistula, 36 (2.4%) esophagogastric/esophagojejunal anastomotic fistula, 29 (1.9%) gastric fistula and 21 (1.4%) cholangiopancreatiointestinal. Among all the simple ECF patients, 991 were tubular fistula and 359 were labial fistula. A total of 1146 patients finished the treatment, of whom 1061 (92.6%) were healed (586 by surgery and 475 self-healing) and 85 (7.4%) died. A total of 1043 patients (91.0%) received nutritional support therapy, and 77 (6.7%) received fistuloclysis. Infectious source control procedures were applied to 1042 patients, including 711 (62.0%) with active lavage and drainage and 331 (28.9%) with passive drainage. Among them, 841 patients (73.4%) underwent minimally invasive procedures of infectious source control (replacement of drainage tube through sinus tract, puncture drainage, etc.), 201 (17.5%) underwent laparotomy drainage, while 104 (9.1%) did not undergo any drainage measures. A total of 610 patients (53.2%) received definitive operation, 24 patients died within postoperative 30-day with mortality of 3.9% (24/610), 69 (11.3%) developed surgical site infection (SSI), and 24 (3.9%) had a relapse of fistula. The highest cure rate was achieved in ileocecal fistula (100%), followed by rectal fistula (96.2%, 128/133) and duodenal stump fistula (95.7%,44/46). The highest mortality was found in combined internal fistula (3/12) and no death in ileocecal fistula. Univariate prognostic analysis showed that primary diseases as Crohn′s disease (χ2=6.570, P=0.010) and appendicitis/appendiceal abscess (P=0.012), intestinal fistula combining with internal fistula (χ2=5.460, P=0.019), multiple ECF (χ2=7.135, P=0.008), esophagogastric / esophagojejunal anastomotic fistula (χ2=9.501, P=0.002), ECF at ileocecal junction (P=0.012), non-drainage/passive drainage before the diagnosis of intestinal fistula (χ2=9.688, P=0.008), non-drainage/passive drainage after the diagnosis of intestinal fistula (χ2=9.711, P=0.008), complicating with multiple organ dysfunction syndrome (MODS) (χ2=179.699, P<0.001), sepsis (χ2=211.851, P<0.001), hemorrhage (χ2=85.300, P<0.001), pulmonary infection (χ2=60.096, P<0.001), catheter-associated infection (χ2=10.617, P=0.001) and malnutrition (χ2=21.199, P<0.001) were associated with mortality. Multivariate prognostic analysis cofirmed that sepsis (OR=7.103, 95%CI:3.694-13.657, P<0.001), complicating with MODS (OR=5.018, 95%CI:2.170-11.604, P<0.001), and hemorrhage (OR=4.703, 95%CI: 2.300-9.618, P<0.001) were independent risk factors of the death for ECF patients. Meanwhile, active lavage and drainage after the definite ECF diagnosis was the protective factor (OR=0.223, 95%CI: 0.067-0.745, P=0.015).@*Conclusions@#The overall mortality of ECF is still high. Surgical operation is the most common cause of ECF. Complications e.g. sepsis, MODS, hemorrhage, and catheter-associated infection, are the main causes of death. Active lavage and drainage is important to improve the prognosis of ECF.

Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary.@*RESULTS@#A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001).@*CONCLUSIONS@#The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.

ABSTRACT

Objective The risk of current pancreaticojejunostomy is carefully considered from the perspective of the morphology of remnant pancreas,and we aimed to discuss the clinical outcomes of selecting different pancreaticojejunostomy techniques based on pancreatic morphology.Methods This was a prospective cohort study.The histopathology of remnant pancreatic tissues was categorized into four types based on preoperative radiological images and intraoperative palpation:Type Ⅰ:pancreas with hard texture in palpation,pancreatic atrophy,dilated pancreatic duct larger than 5 mm and remnant pancreatic surface <3 cm;Type Ⅱ:pancreas with hard texture in palpation,pancreatic atrophy and mild dilatation of pancreatic duct with the diameter of 3-5 mm and remnant pancreatic surface <3 cm;Type Ⅲ:pancreas with slightly hard texture,no atrophy,and normal or slightly dilated pancreatic duct with the diameter of 3-5 mm and remnant pancreatic surface ≥3 cm;Type Ⅳ:pancreas with soft texture,normal morphology and pancreatic duct.Results From January 2008 to August 2017,116 consecutive patients underwent pancreaticoduodenectomy in our center.Among them,10 patients with type Ⅰ underwent classic pancreatic ductal mucosa to mucosa anastomosis.19 patients with type Ⅱ underwent classic end to end invaginated pancreaticojejunostomy.45 patients with type Ⅲ underwent classic end to end invaginated pancreaticojejunostomy with overlapping U sutures;42 patients with type Ⅵ underwent total invaginated pancreaticojejunostomy.The post-operative pancreatic fistula occurred in 6 patients (5.2%) with one patient died.Postoperative bleeding occurred in 10 patients (8.6%),and gastroparesis occurred in 22 patients (19.0%).Overall complication rate was 33.6%.Conclusions Classification of pancreatic morphology based on preoperative radiological images and intraoperative palpation and the selection of corresponding pancreaticojejunostomy technique is theoretically rational and has the advantage of potentially reducing the risk of remnant pancreatic tissue.

ABSTRACT

Objective To explore the inhibitory effects of sulfated oligosaccharides PI-88 on the heparanase protein expression of human esophageal squamous cancer cell (ESCC) line TE-13, and to explore the effects of growth, angiogenesis and heparanase protein expression on ESCC xenografts of nude mice. Methods TE-13 cells were cultured and divided into three groups:group A (control group), group B (15 mg/L PI-88) and group C (30 mg/L PI-88). Heparanase protein expression of TE-13 cells was measured by Western blot assay after being cultured for 36 h. The ESCC suspension was injected subcutaneously in 10 BALB/c/nu mice to build up ESCC xenograft model. The model mice were divided randomly into observation group and control group (5 mice per group). The mice in observation group received 40 mg/(kg·d) PI-88. The mice in control group only received the same volume of saline at the same time. Both PI-88 and saline were daily administrated for 14 days. Every 2 days,the volume of xeongrafts were measured and the mice were executed at the 14th day. CD34 immunohistochemical staining was used to detect the micro vessel density (MVD) of xenografts. Western blot assay and immunohistochemical staining were used to detect the heparanase protein expression of xenografts. Results The heparanase protein expressions of TE-13 cells were significantly decreased in group B and group C than those of group A (P<0.001), with a kind of PI-88 dose-dependent manner. The volume, MVD and heparanase protein expression of xenografts were significantly lower in observation group than those of control group (P<0.05). Conclusion The heparanase protein expression in TE-13 cells can be inhibited by PI-88 in vitro and vivo. Furthermore, the growth and angiogenesis of ESCC xenografts were also inhibited by PI-88.
