OBJECTIVETo investigate the types and therapies of malignancies in renal allograft recipients.
METHODSWe retrospectively analyzed the occurrence, types, and therapies of malignancies in 498 renal allograft recipients who had received operations in Peking Union Medical College Hospital from May 1986 to October 2008.
RESULTSAmong 498 renal allograft recipients, 18 patients (3.6% ) were diagnosed with malignancies, which included bladder cancer (n = 5), renal pyloric cancer or ureteric cancer (n = 4), leukemia or lymphoma (n = 3), hepatic cancer (n = 2), skin cancer, rectum carcinoma, pulmonary carcinoma and thymoma (n = 1 each). Surgical operations were performed in 10 cases, 6 of whom survived with normal renal function and had no rejection of transplanted kidneys. Three patients with bladder cancer and one patient with ureteric cancer experienced recurrences 7 to 15 months after operations; among them one bladder cancer patient died. One hepatic carcinoma patient died of pulmonary metastasis 8 months after operation. One non-Hodgkin's lymphoma patient died 11 months after chemotherapy. Five cases with advanced unresectable malignancies died 8 to 17 months after the diagnosis.
CONCLUSIONSThe incidences of malignancies, especially urological epithelial carcinoma, are high in renal allograft recipients. Radical surgery of the solid malignancies is a preferred option.

BACKGROUNDThe effectiveness of chemoradiotherapy followed by surgery (CRTS) in patients with resectable esophageal carcinoma remains controversial. We performed a systematic review of the literature with meta-analysis.
METHODSElectronic databases were used to identify published studies between January 1992 and April 2012. Pooled relative risk (RR) with 95% confidence interval (95% CI) was utilized to estimate the strength of the association between CRTS and surgery alone (SA) survival of the resectable esophageal carcinoma patients. Heterogeneity and publication bias were also assessed in the present study.
RESULTSThe final analysis of 2755 resectable esophageal carcinoma cases from 21 randomized controlled trials (RCTs) are presented. Compared to the SA group, the 1, 3- and 5-year survival rates were significantly higher in the CRTS group (all P < 0.05); the 3- and 5-year survival rates for the Eastern patients, Western patients, patients undergoing concurrent chemoradiotherapy, patients with squamous cell carcinoma, patients undergoing High-dose radiotherapy (≥ 40 Gy), and patients given either "cisplatin + Fluorouracil" or "cisplatin + paclitaxel" chemotherapy were significantly higher in the CRTS group (all P < 0.05). There were no statistical significances in the 3- and 5-year survival rates for patients undergoing sequential chemoradiotherapy or patients with adenocarcinoma between the two groups (all P > 0.05). Compared to the RCTS group, the surgery rate in the SA group was higher (P < 0.05), while the CRTS group had significantly higher radical resection rate, R0 resection rate and lower postoperative local recurrence rate (all P < 0.05). The differences in postoperative complication incidence, post-operative distant metastasis and postoperative mortality rate were not statistically significant between the two groups (all P > 0.05).
CONCLUSIONCRTS can significantly improve the survival and surgical conditions of patients with resectable esophageal carcinoma.

Objective Although goal-directed fluid therapy (GDFT) has been proven to be effective in reducing the incidence of postoperative complications, the underlying mechanisms remain unknown. The aim of this study was to examine the mediating role of intraoperative hemodynamic lability in the association between GDFT and the incidence of postoperative complications. We further tested the role of this mediation effect using mean arterial pressure, a hemodynamic indicator. Methods This secondary analysis used the dataset of a completed nonrandomized controlled study to investigate the effect of GDFT on the incidence of postoperative complications in patients undergoing posterior spine arthrodesis. We used a simple mediation model to test whether there was a mediation effect of average real variability between the association of GDFT and postoperative complications. We conducted mediation analysis using the mediation package in R (version 3.1.2), based on 5,000 bootstrapped samples, adjusting for covariates. Results Among the 300 patients in the study, 40% (120/300) developed postoperative complications within 30 days. GDFT was associated with fewer 30-day postoperative complications after adjustment for confounders (odds ratio: 0.460, 95% CI: 0.278, 0.761; P = 0.003). The total effect of GDFT on postoperative complications was -0.18 (95% CI: -0.28, -0.07; P < 0.01). The average causal mediation effect was -0.08 (95% CI: -0.15, -0.04; P < 0.01). The average direct effect was -0.09 (95% CI: -0.20, 0.03; P = 0.17). The proportion mediated was 49.9% (95% CI: 18.3%, 140.0%). Conclusions The intraoperative blood pressure lability mediates the relationship between GDFT and the incidence of postoperative complications. Future research is needed to clarify whether actively reducing intraoperative blood pressure lability can prevent postoperative complications.

OBJECTIVETo investigate clinical features and treatments of cervical spinal injury in aged patients.
METHODSFrom July 2006 to October 2011, 27 patients with cervical spinal cord injury were divided into experiment group, including 20 males and 7 females with an average age of 69 years old (ranged 65 to 78 years old). The other 22 patients with the same degree of cervical spianl cord injury and the same period hospitalization were chosen to regard as control group, including 16 males and 6 females with an average age of 47 years old (ranged 38 to 65 years old). All of them had clear history of trauma, and were admitted to hospital within one week. Clinical data and result of follow up were evaluated between two group. The function of the spinal cord was measured by Frankel classification at admission and final follow-up.
RESULTSAll patients were followed up for 1 year except 6 died in aged group, among which 3 paients with complications were died during hospitalization and others were out of hospital. Twenty-three cases had accompanied diseases and 24 cases occurred complications in aged group. Contrast to control group, this difference was statistically significant. At the final follow-up, there were 2 cases at Frankel grade E in aged group and 6 cases in control group.
CONCLUSIONIn comparison with control group, there are more accompany diseases and higher complications and mortality rates in aged group, while poor improvement of spinal cord function. This patients were mainly treated with operation, but operation method should simplify and mainly focus on effective decompression and reconstuction stability and avoid expansion operation. It's nesscerry to pay more attention to prevent and treatment of respiratory complication.

PURPOSE: Compared with warfarin, novel oral anticoagulants (NOACs) are convenient to use, although they require a blanking period immediately before radiofrequency catheter ablation for atrial fibrillation (AF). We compared NOACs and uninterrupted warfarin in the peri-procedural period of AF ablation. MATERIALS AND METHODS: We compared 141 patients treated with peri-procedural NOACs (72% men; 58+/-11 years old; 71% with paroxysmal AF) and 281 age-, sex-, AF type-, and history of stroke-matched patients treated with uninterrupted warfarin. NOACs were stopped 24 hours before the procedure and restarted on the same procedure day after hemostasis was achieved. RESULTS: We found no difference in the CHA2DS2-VASc (p=0.376) and HAS-BLED scores (p=0.175) between the groups. The preprocedural anticoagulation duration was significantly shorter in the NOAC group (76.3+/-110.7 days) than in the warfarin group (274.7+/-582.7 days, p<0.001). The intra-procedural total heparin requirement was higher (p<0.001), although mean activated clotting time was shorter (350.0+/-25.0 s vs. 367.4+/-42.9 s, p<0.001), in the NOAC group than in the warfarin group. There was no significant difference in thromboembolic events (1.4% vs. 0%, p=0.111) or major bleeding (1.4% vs. 3.9%, p=0.235) between the NOAC and warfarin groups. Minor stroke occurred in two cases within 10 hours of the procedure (underlying CHA2DS2-VASc scores 0 and 1) in the NOAC group. CONCLUSION: Pre-procedural anticoagulation duration was shorter and intra-procedural heparin requirement was higher with NOAC than with uninterrupted warfarin during AF ablation. Although the peri-procedural thromboembolism and bleeding incidences did not differ, minor stroke occurred in two cases in the NOAC group.

PURPOSETo evaluate the clinical outcomes of locking calcaneal plate in treating calcaneal fracture (Sanders II-III) in elderly patients.
METHODSFrom October 2012 to December 2013, 23 elderly patients suffering from calcaneal fracture (Sanders II-III) were treated and followed up. There were 15 males and 8 females with the mean age of 68.5 years (range: 65-79 years). According to Sander's classification, 16 cases (16 feet) were type II fractures and 7 cases (7 feet) were type III fractures. Anteroposterior, lateral and axial views of X-ray were taken to detect the calcaneum. CT scan was done to assess the amount of comminution and articular depression. Radiological assessment was performed using Bohler's angle and Gissane's angle. Functional outcome was assessed using the Maryland foot score.
RESULTSAll the patients were followed up for 13.7 months on average (10-20 months). The mean time of bone union was 3.2 months (3-4 months). The mean time of complete weight bearing was 3.2 months (3.1-4.0 months). The soft tissue necrosis was found in 1 case. The mean Bohler's angle and Gissane's angle were 25.31° and 117.5°respectively. The overall excellent to good rate was 82.6%.
CONCLUSIONOpen reduction and internal fixation with locking calcaneal plate can obtain good functional outcome for Sanders II-III calcaneal fractures in elderly patients.

BACKGROUND: Femoral neck fractures are rare injuries in children, but the high incidence of long term complications make it an important clinical entity. The aim of this retrospective study was to analyze the clinical outcomes of pediatric femur neck fractures that we managed over a 10 year period. METHODS: The study included 36 children (20 boys and 16 girls) who sustained femoral neck fractures and completed a minimum follow-up of one year. The children were treated either conservatively, or by open reduction and internal fixation (ORIF), or closed reduction and internal fixation (CRIF). The outcomes were analyzed using Ratliff criteria and a detailed record of complications was kept for all patients. RESULTS: The mean age of included patients was 10 years (range, 3 to 16 years) and the average follow-up was 3.2 years (range, 1.1 to 8.5 years). Based on Delbet's classification system, there were 0 type I (transepiphyseal), 16 type II, 11 type III, and 9 type IV fractures. There were 8 undisplaced fractures, 4 of which later displaced after being managed initially in a hip spica. A satisfactory outcome was obtained in 27 (75%) children. Avascular necrosis (AVN) was the most common complication. It was seen in 7 of our patients, all of whom had an unsatisfactory outcome. Other complications included three cases each of coxa vara, non-union, and arthritic changes; and one case each of infection, primary screw perforation of head, and premature epiphyseal closure. Complications were lowest in the group treated by ORIF. Only 2 patients managed exclusively by conservative treatment ultimately achieved a satisfactory outcome. CONCLUSIONS: We believe that internal fixation of pediatric femoral neck fractures is preferred whenever feasible because conservative treatment carries a high risk of failure of reduction. Aggressive operative treatments aimed at anatomical reduction should be the goal and there should be no hesitation in choosing ORIF over CRIF. Outcome of patients is influenced primarily by development of AVN which occurs as an independent entity without much relation to the mode of treatment carried out.

The medical records of six cases of nesidioblastosis were examined to determine the diagnostic approach, treatment, and neurologic sequelae. All six patients were male, and their ages at the onset of the disease ranged from one day to six months (mean 3.36 +/- 2.5 mo.). Initial clinical features were seizure, cyanosis, poor feeding, and apnea. Other subsequent symptoms were developmental delay, hyperactivity, and cold sweating. The Birth weight of the neonatal onset group was heavier than the postneonatal onset group (4.4 +/- 0.3 vs 3.26 +/- 0.04 kg). Before the diagnosis of hyperinsulinism, steroids of ACTH proved effective for seizure control. Initially, hyperinsulinemia (serum insulin greater than 10 microU/ml) was detected in four cases, but another two cases also showed hyperinsulinism by insulin/glucose(I/G) ratio greater than 0.3 during the fasting test. The glucagon response performed in 2 cases, showed normal and partial responses. Euglycemia was obtained by near total pancreatectomy (95% pancreatic resection)without malabsorption or persistent diabetes. In one case, nesidioblastoma coexisted with nesidioblastosis. Developmental delay was noted in three cases. In this group, the mean duration between symptom onset and operation was longer than the group without developmental delay (1.25 +/- 0.47 vs 0.38 +/- 0.19 yr).

Chinese Journal of Gastrointestinal Surgery 2017;20(3):300-303
OBJECTIVETo compared the clinical efficacy of laparoscopic repair (LR) versus open repair (OR) for perforated peptic ulcers.
METHODSFrom January 2010 to June 2014, in Shanghai Tongji Hospital, 119 patients who were diagnosed as perforated peptic ulcers and planned to receive operation were prospectively enrolled. Patients were randomly divided into LR (58 patients) and OR(61 patients) group by computer. Intra-operative and postoperative parameters were compared between two groups. This study was registered as a randomized controlled trial by the China Clinical Trials Registry (registration No.ChiCTR-TRC-11001607).
RESULTSThere was no significant difference in baseline data between two groups (all P>0.05). No significant differences of operation time, morbidity of postoperative complication, mortality, reoperation probability, decompression time, fluid diet recovery time and hospitalization cost were found between two groups (all P>0.05). As compared to OR group, LR group required less postoperative fentanyl [(0.74±0.33) mg vs. (1.04±0.39) mg, t=-4.519, P=0.000] and had shorter hospital stay [median 7(5 to 9) days vs. 8(7 to 10) days, U=-2.090, P=0.001]. In LR group, 3 patients(5.2%) had leakage in perforation site after surgery. One case received laparotomy on the second day after surgery for diffuse peritonitis. The other two received conservative treatment (total parenteral nutrition and enteral nutrition). There was no recurrence of perforation in OR group. One patient of each group died of multiple organ dysfunction syndrome (MODS) 22 days after surgery.
CONCLUSIONLR may be preferable for treating perforated peptic ulcers than OR, however preventive measures during LR should be taken to avoid postopertive leak in perforation site.
