BACKGROUND: A retrospective review of the surgical treatment of refractory chest tumors involving the heart or large vessels with cardiopulmonary bypass (CPB). METHODS: To summarize 11 cases of chest tumor patients who had undergone cardiopulmonary bypass surgery from January 2008 to May 2017 in our hospital, and analyze the general condition, clinical characteristics, treatment methods, postoperative hospitalization time, complications and follow-up results of all patients. RESULTS: All 11 patients were operated with cardiopulmonary bypass. Total resection of tumors in 8 cases and most of the excision in 3 cases. 1 case of left atrial metastatic leiomyosarcoma were excised in the left atrium, and then the right lung resection was performed. 1 case of left lung central lung cancer resection through the median sternum incision. 2 cases underwent pulmonary artery repair at the same time, 3 cases underwent partial pericardiectomy and 3 cases underwent pulmonary wedge resection at the same time. All the patients were effectively relieved after the operation. No death rate in hospital and 30 days after operation. 3 cases of postoperative pulmonary infection were recovered after the treatment of antibiotics. 1 case of lymphoma relapsed 6 months after surgery and died one year later. 1 case of pericardial fibrosarcoma had local recurrence and extensive metastasis at 13 months after operation, and died after 15 months. 1 case of pulmonary leiomyosarcoma were found to have local recurrence 15 months after the operation and were relieved after chemotherapy. The remaining 8 patients survived, and no obvious recurrence and distant metastasis were found in the computed tomography (CT) examination. CONCLUSIONS The CPB assisted surgical treatment can be performed for patient of refractory chest tumors involving the heart or large vessels. It can improve the surgical resection rate of refractory chest tumors, effectively alleviate the effects on respiratory and circulatory functions, and significantly prolong the survival period of these patients.

OBJECTIVETo analyze the change in postoperative complication rate after gastric cancer surgery registered in the Peking University Cancer Hospital in recent 11 years and the learning curve of complication registration, and to investigate how to improve the complication registration and evaluation in gastric cancer surgery.

METHODSPatients who underwent open or laparoscopic gastric cancer surgery between April 14, 2005 and February 15, 2016 in our institution were included in the study, and those without essential clinical and administrative data were excluded. Data were biennially collected, and linear regression was performed to investigate the changes of the following parameters, including overall complication rate, severe complication proportion (proportion of complications with Clavien-Dindo score ≥III(a in the total registered complications), re-operation rate and the major complication rate.

RESULTSA total of 5 666 patients were included in the analysis, with 4 111 males (72.56%) and 1 555 females (27.44%). The average age was (58.87±11.50) years and average BMI was(23.15±3.30) kg/m. There were 305 patients included in the 2005-2006 interval, 810 patients in 2007-2008, 957 patients in 2009-2010, 1 163 patients in 2011-2012, 1 421 patients in 2013-2014, and 1 010 patients in 2015-2016, respectively. The overall re-operation rate was 2.34%(133/5 666), postoperative mortality was 0.41%(23/5 666), registered complication rate was 19.66%(1 114/5 666), severe complication proportion was 32.28%(338/1 047), and the proportion of complication missing the Clavien-Dindo score was 6.01%(67/1 114). The linear regression showed the re-operation rate (r=0.13, P=0.801) and postoperative mortality (r=0.58, P=0.231) remained low (< 4% and < 1% respectively) since 2005, and showed no statistical significance. The registered complication rate showed evident increase from 3.93%(12/305) to 29.13%(414/1 421) between 2005 and 2014 (r=0.92, P=0.010), and slight decrease to 22.77%(230/1 010) in 2015-2016. The severe complication proportion significantly decreased from 6/9 in 2005-2006 to 22.73%(50/220) in 2015-2016 (r=0.90, P=0.014). The proportion of complication missing the Clavien-Dindo score significantly decreased from 25.00%(3/12) in 2005-2006 to 4.35%(10/230) in 2015-2016(r=0.82, P=0.044). The most common complications were infection (9.12%, 517 cases), effusions (6.26%, 355 patients), gastrointestinal motility disorder (4.45%, 252 cases), anastomotic leakage (3.19%, 181 cases) and bleeding (2.31%, 131 cases). The registered rates of these complications all increased since 2005, and the rates of leakage and effusions decreased since 2012 while the others decreased after 2014.

CONCLUSIONSAccording to the data from our institution in the recent 11 years, a learning curve exists in our institution for complication registration in gastric cancer surgery. The administrative data appears to be more reliable than registered complication data in quality and safety evaluation during the learning period. A detailed classification with the Clavien-Dindo score aids to the use of complication data for the quality and safety measurement.

Incidence of gastric cancer is high in China and standard radical operation is currently the main treatment for gastric cancer. Postoperative complications, especially some special complications, can directly affect the prognosis of patients, even result in the increase of mortality. But the incidences of these special complications are low, so these complications are often misdiagnosed and delayed in treatment owing to insufficient recognition of medical staff. These special complications include (1) Peterson hernia: It is an abdominal hernia developed in the space between Roux loop and transverse colon mesentery after Roux-Y reconstruction of digestive tract. Peterson hernia is rare and can quickly result in gangrenous ileus. Because of low incidence and without specific clinical symptoms, this hernia does not attract enough attention in clinical practice, so the outcome will be very serious. Once the diagnosis is made, an emergent operation must be performed immediately. Peterson space should be closed routinely in order to avoid the development of hernia. (2) Lymphatic leakage: It is also called chyle leakage. Cisterna chylus is formed by gradual concentration of extensive lymphatic net to diaphragm angle within abdominal cavity. Lymphadenectomy during operation may easily damage lymphatic net and result in leakage. The use of ultrasonic scalpel can decrease the risk of lymphatic leakage in certain degree. If lymphatic leakage is found during operation, transfixion should be performed in time. Treatment includes total parenteral nutrition, maintenance of internal environment, supplement of protein, and observation by clamp as an attempt. (3)Duodenal stump leakage: It is one of serious complications affecting the recovery and leading to death after subtotal gastrectomy. Correct management of duodenal stump during operation is one of key points of the prevention of duodenal stump leakage. Routine purse embedding of duodenal stump is recommend during operation. The key treatment of this complication is to promt diagnosis and effective hemostasis.(4) Blood supply disorder of Roux-Y intestinal loop: Main preventive principle of this complication is to pay attention to the blood supply of vascular arch in intestinal edge. (5) Anastomotic obstruction by big purse of jejunal stump: When Roux-en-Y anastomosis is performed after distal radical operation for gastric cancer, anvil is placed in the remnant stomach and anastomat from distal jejunal stump is placed to make gastrojejunal anastomosis, and the stump is closed with big purse embedding. The embedding jejunal stump may enter gastric cavity leading to internal hernia and anastomotic obstruction. We suggest that application of interruptable and interlocking suture and fixation of stump on the gastric wall can avoid the development of this complication.

OBJECTIVETo analyze the perioperative clinical data of children with congenital heart disease complicated by acute kidney injury (AKI) after cardiopulmonary bypass (CPB) surgery, and to explore potential factors influencing the prognosis.

METHODSA retrospective analysis was performed among 118 children with congenital heart disease who developed AKI within 48 hours after CPB surgery.

RESULTSIn the 118 patients, 18 died after 48 hours of surgery. Compared with the survivors, the dead children had significantly higher incidence of cyanotic disease and Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1) scores before surgery; during surgery, the dead children had significantly longer CPB time and aortic cross-clamping time, a significantly higher proportion of patients receiving crystalloid solution for myocardial protection, and a significantly higher mean blood glucose level. Within 48 hours after surgery, the dead children had significantly higher positive inotropic drug scores, significantly higher creatinine values, a significantly higher incidence of stage 3 AKI, a significantly higher proportion of patients receiving renal replacement the, and significantly higher usage of blood products (P<0.05). The mortality rate of the patients increased with increased intraoperative blood glucose levels (P<0.05). Patients with intraoperative blood glucose levels >8.3 mmol/L had a significantly lower postoperative cumulative survival rate and a significantly shorter mean survival time than those with blood glucose levels ≤ 8.3 mmol/L (P<0.05).

CONCLUSIONSIntraoperative blood glucose levels are associated with the prognosis in children with congenital heart disease complicated by AKI after CPB surgery. Maintaining good intraoperative blood glucose control can improve the prognosis of the children.

BACKGROUNDBalanced adjustment of the portal vein shunt volume during a transjugular intrahepatic portosystemic shunt (TIPS) is critical for maintaining liver perfusion and decreasing the incidence of liver insufficiency. A stent-graft is proved to be superior to a bare metal stent (BMS) for the construction of a TIPS. However, the clinical results of the combination application of stents and stent-grafts have not been determined. This study aimed to compare the technique of using a combination of stents and stent-grafts with using a single stent-graft to construct a TIPS.

METHODSFrom April 2011 to November 2014, a total of fifty patients were randomly assigned to a stents-combination group (Group I, n = 28) or a stent-graft group (Group II, n = 22). Primary patency rates were calculated. Clinical data, including the technical success rate, bleeding control results, incidence of encephalopathy, liver function preservation, and survival rate, were assessed.

RESULTSTechnically, the success rate was 100% for both groups. The primary patency rates at 1, 2, and 3 years for Group I were 96%, 84%, and 77%, respectively; for Group II, they were 90%, 90%, and 78%, respectively. The survival rates at 1, 2, and 3 years for Group I were 79%, 74%, and 68%, respectively; for Group II, they were 82%, 82%, and 74%, respectively. The incidence of hepatic encephalopathy was 14.3% for Group I and 13.6% for Group II. The Child-Pugh score in Group I was stable at the end of the follow-up but had significantly increased in Group II (t = -2.474, P = 0.022).

CONCLUSIONSThe construction of a TIPS with either the single stent-graft or BMS/stent-graft combination is effective for controlling variceal bleeding. The BMS/stent-graft combination technique is superior to the stent-graft technique in terms of hepatic function preservation indicated by the Child-Pugh score. However, considering the clinical results of the TIPS, the two techniques are comparable in their primary shunt patency, incidence of encephalopathy and patient survival during the long-term follow-up.

BACKGROUNDGastrojejunostomy (GJJ) and endoscopic stenting (ES) are palliative treatments for gastric outlet obstruction (GOO) caused by gastric cancer. We compared the outcomes of GJJ with ES by performing a meta-analysis.

METHODSClinical trials that compared GJJ with ES for the treatment of GOO in gastric cancer were included in the meta-analysis. Procedure time, time to resumption of oral intake, duration of hospital stay, patency duration, and overall survival days were compared using weighted mean differences (WMDs). Technical success, clinical success, procedure-related mortality, complications, the rate of re-obstruction, postoperative chemotherapy, and reintervention were compared using odds ratios (OR s).

RESULTSNine studies were included in the analysis. Technical success and clinical success were not significantly different between the ES and GJJ groups. The ES group had a shorter procedure time (WMD = -80.89 min, 95% confidence interval [CI] = -93.99 to -67.78,P < 0.001), faster resumption of oral intake (WMD = -3.45 days, 95% CI = -5.25 to -1.65,P < 0.001), and shorter duration of hospital stay (WMD = -7.67 days, 95% CI = -11.02 to -4.33,P < 0.001). The rate of minor complications was significantly higher in the GJJ group (OR = 0.13, 95% CI = 0.04-0.40,P < 0.001). However, the rates of major complications (OR = 6.91, 95% CI = 3.90-12.25,P < 0.001), re-obstruction (OR= 7.75, 95% CI = 4.06-14.78,P < 0.001), and reintervention (OR= 6.27, 95% CI = 3.36-11.68,P < 0.001) were significantly lower in the GJJ group than that in the ES group. Moreover, GJJ was significantly associated with a longer patency duration (WMD = -167.16 days, 95% CI = -254.01 to -89.31,P < 0.001) and overall survival (WMD = -103.20 days, 95% CI = -161.49 to -44.91, P= 0.001).

CONCLUSIONSBoth GJJ and ES are effective procedures for the treatment of GOO caused by gastric cancer. ES is associated with better short-term outcomes. GJJ is preferable to ES in terms of its lower rate of stent-related complications, re-obstruction, and reintervention. GJJ should be considered a treatment option for patients with a long life expectancy and good performance status.

OBJECTIVETo compare the short-term efficacy and long-term survival between Sweet and Ivor-Lewis esophagectomy for patients with middle-lower esophageal squamous cell carcinoma.

METHODSClinicopathologic data of 1 308 patients with middle-lower esophageal squamous cell carcinoma undergoing Sweet or Ivor-Lewis procedures in our department from January 2007 to December 2014 were retrospectively analyzed, including 1 021 patients of Sweet operation (Sweet group) and 287 patients of Ivor-Lewis operation(Ivor-lewis group). Lymph node clearance, lymphatic metastasis, postoperative complication morbidity and long-term survival were compared between the two groups.

RESULTSThere were no significant differences in baseline data between the two groups(all P>0.05). There were more lymph nodes resected during the Ivor-Lewis procedure compared with the Sweet procedure (20.8 vs.19.3, P=0.030). Compared with Ivor-Lewis group, the incidence of wound infection in Sweet group was significantly lower[(3.2%(33/1 021) vs. 8.0%(23/287), P=0.000]. Sweet group had a significantly lower rate of delayed gastric emptying[1.9%(19/1 021) vs. 5.2%(15/287), P=0.002] and significantly shorter hospital stay (14.7 days vs. 17.2 days, P=0.029). With respect to other postoperative complications, such as pulmonary complications, cardiac events, anastomotic leakage, vocal cord palsy, chylothorax and pyothorax, the differences between the two groups were not statistically significant. The 5-year survival rate was not significantly different between the two group (54.0% vs. 56.9%, P=0.873). Stratified analysis based on TNM staging showed that no significant difference of 5-year survival rate was found between the two groups in stageI( and stageIII( patients (P>0.05), while the 5-year survival rate of stageII( patients in Sweet group was significantly lower than that in Ivor-Lewis group (56.4%% vs. 70.4%, P=0.039).

CONCLUSIONSFor patients with middle-lower esophageal squamous cell carcinoma, Sweet procedure has certain superiority regarding the incidence of wound infection and delayed gastric emptying compared with the Ivor-Lewis procedure. Ivor-Lewis esophagectomy can harvest more lymph nodes. The 5-year survival rate of these two procedures is similar. Sweet procedure is still valuable in clinical practice, especially for stageI( and stageIII( patients, while it requires thorough considerations for stageII( patients.

OBJECTIVETo investigate the clinical value of Physiologic Ability and Surgical Stress (E-PASS) and modified Estimation of Physiologic Ability and Surgical Stress (mE-PASS) scoring systems in predicting the mortality and surgical risk of gastric cancer patients, and to analyze the relationship between the parameters of E-PASS and early postoperative complications.

METHODSClinical data of 778 gastric cancer patients who underwent elective surgical resection in Tianjin Medical University General Hospital from Jan. 2010 to Jan. 2014 were analyzed retrospectively. E-PASS and mE-PASS scoring systems were used to predict the mortality of gastric cancer patients, respectively. Univariate and unconditioned logistic regression analyses were performed to assess the relationships between nine parameters of E-PASS system and early postoperative complications.

RESULTSE-PASS and mE-PASS systems were used to predict the mortality in the death group and non-death group. The Z value was -5.067 and -4.492, respectively, showing a significant difference between the two groups (P<0.05). AUCs of mortality predicted by E-PASS and mE-PASS were 0.926 and 0.878 (P>0.05), and the prediction calibration of postoperative mortality showed statistically non-significant difference (P>0.05) between the E-PASS and mE-PASS prediction and actual mortality. Univariate analysis showed that age, operation time, severe heart disease, severe lung disease, diabetes mellitus, physical state index and ASA classification score are related to postoperative complications (P<0.05 for all). Unconditioned logistic regression analysis showed that severe lung disease, diabetes mellitus, ASA classification score and operation time are risk factors for early postoperative complications (P<0.05 for all).

CONCLUSIONSBoth mE-PASS and E-PASS scoring system have good consistency in the predicting postoperative mortality and actual mortality, and both are suitable for clinical application. Moreover, the mE-PASS scoring system is clinically more simple and convenient than E-PASS scoring system. Preoperative severe lung disease, diabetes mellitus, ASA classification score and operation time are independent factors affecting the early postoperative complications.

OBJECTIVETo summarize the clinical characteristics, early diagnosis, comprehensive treatment and prognosis of 6 cases of children with post-transplantation lymphoproliferative disorder (PTLD) after liver transplantation.

METHODData of 6 cases with PTLD seen between January 2011 and December 2013 were retrospectively analyzed. The anti-rejection drug dose adjustments, the effect of rituximab, antiviral therapy and comprehensive treatment program after surgery were explored.

RESULT(1) The diagnosis of PTLD was confirmed by histologic findings. Six cases of PTLD including 3 males and 3 females were diagnosed as congenital biliary atresia and underwent split liver transplantation. The occurrence rate of PTLD was 2.9%. (2) The median time to the development of PTLD was less than 6 months. The initial symptom of PTLD in all patients was fever and clinical manifestations of PTLD were non-specific, depending on the involving organs. Five cases of PTLD developed gastrointestinal symptoms, including diarrhea, abdominal pain, and abdominal distension. One case developed respiratory symptoms, including cough and tachypnea. Three cases had lymph node involvement. In 2 cases pathophysiology involved polymorphic lymphocyte proliferation and in 4 cases B lymphocyte proliferation. (3) Two cases died, in whom EBV DNA was not detected and were diagnosed as PTLD by surgical pathology before death. Four survived cases had high EBV-DNA load and then were diagnosed as PTLD by biopsy pathology. (4) Of the 6 cases of PTLD, 2 cases died and 4 cases survived. The overall mortality was 33%. The dead cases were only treated with laparotomy because of intestinal obstruction or perforation and the survived cases were treated with tacrolimus at reduced doses or discontinuation and rituximab. In 2 cases antiviral therapy (acyclovir) was continued, including 1 cases of intestinal obstruction treated with surgical repair. All the survived patients were followed up for 4 months to 1 year and no evidence has been found.

CONCLUSIONEBV infection is the high risk factor for PTLD after liver transplantation. Close clinical surveillance of EBV DNA for pediatric liver transplantation was important for the early diagnosis of PTLD. Reducing doses of immunosuppressive agents and rituximab is the initial therapy for PTLD. A reduction in the dose of tacrolimus is suggested. Operation therapy can also play a role in the management of local complications.
