Simulation-based care pathway approach (CPA) training is a novel approach in surgical education. The objective of the present study was to determine whether CPA was feasible for training surgical residents and could improve efficiency in patients’ management. A common disease was chosen: acute appendicitis.
MethodsAll five junior residents of our department were trained in CPA: preoperative CPA consisted in virtual patients (VPs) presenting with acute right iliac fossa pain; intraoperative CPA involved a virtual competency-based curriculum for laparoscopic appendectomy (LAPP); finally, post-operative VP were reviewed after LAPP. Thirty-eight patients undergoing appendectomy were prospectively included before (n = 21) and after (n = 17) the training. All demographic and perioperative data were prospectively collected from their medical records, and time taken from admission to management was measured.
ResultsAll residents had performed less than 10 LAPP as primary operator. Pre- and intraoperative data were comparable between pretraining and post-training patients. Times to liquid and solid diet were significantly reduced after training [7 h (2–20) vs. 4 (4–6); P = 0.004, and 17 h (4–48) vs. 6 (4–24); P = 0.005] without changing post-operative morbidity [4 (19%) vs. 0 (0); P = 0.11] and length of stay [48 h (30–264) vs. 44 (21–145); P = 0.22].
ConclusionsCPA training is feasible in abdominal surgery. In the current study, it improved patients’ management in terms of earlier oral intake.
相似文献Traumatic Spinal Injuries (TSI) often follow high velocity injuries and frequently accompanied by polytrauma. While most studies have focussed on outcomes of spinal cord injuries, the incidence and risk factors that predict morbidity and mortality after TSI has not been well-defined.
MethodsData of consecutive patients of TSI (n = 2065) treated over a 5-year-period were evaluated for demographics, injury mechanisms, neurological status, associated injuries, timing of surgery and co-morbidities. The thirty-day incidence and risk factors for complications, length of stay and mortality were analysed.
ResultsThe incidence of spinal trauma was 6.2%. Associated injuries were seen in 49.7% (n = 1028), and 33.5% (n = 692) patients had comorbidities. The 30-day mortality was 0.73% (n = 15). Associated chest injuries (p = 0.0001), cervical spine injury (p = 0.0001), ASIA-A neurology (p < 0.01) and ankylosing spondylitis (p = 0.01) correlated with higher mortality. Peri-operative morbidity was noted in 571 patients (27.7%) and were significantly associated with age > 60 (p = 0.043), ASIA-A neurology (p < 0.05), chest injuries (p = 0.042), cervical and thoracic spine injury (p < 0.0001). The mean length of stay in hospital was 8.87 days. Cervical spine injury (p < 0.0001), delay in surgery > 48 h (p = 0.011), Diabetes mellitus (p = 0.01), Ankylosing spondylitis (p = 0.009), associated injuries of chest, head, pelvis and face (p < 0.05) were independent risk factors for longer hospital stay.
ConclusionKey predictors of mortality after spinal trauma were cervical spine injury, complete neurological deficit, chest injuries and ankylosing spondylitis, while additionally higher age and thoracic injuries contributed to higher morbidity and prolonged hospitalisation. Notably multi-level injuries, higher age, co-morbidities and timing of surgery did not influence the mortality.
相似文献The aim of this study was to compare the outcomes of one-step multichannel percutaneous transhepatic cholangioscopic lithotripsy (PTCSL) with traditional PTCSL in the treatment of bilateral hepatolithiasis.
MethodsFrom February 2011 to June 2015, 156 patients with bilateral hepatolithiasis received surgical treatment in our department. Among these patients, 81 received one-step multichannel PTCSL (group A), and the remaining 75 received traditional PTCSL (group B).
ResultsCompared with group B, group A was characterized by a significantly shorter operation time (83.7 ± 28.5 min vs 118.1 ± 41.5 min; P = 0.000), hospital stay (11.1 ± 3.4 d vs 17.8 ± 5.6 d; P = 0.034), and postoperative hospital stay (6.9 ± 3.1 d vs 9.6 ± 4.5 d; P = 0.026). In addition, the immediate clearance (62.9% vs 45.3%, P = 0.027) and final clearance (90.1% vs 78.7%, P = 0.048) rates were higher in group A than in group B. During the follow-up period, stone recurrence was significantly less common in group A than in group B (13.6% vs 26.7%, P = 0.041). Multivariate Cox analysis showed that the PTCSL method (HR = 2.32, 95% confidence interval [CI] = 1.09–4.90, P = 0.028), bilateral biliary stricture (HR = 4.17, 95% CI = 1.73–10.03, P = 0.001), and stones located in segments I (HR = 7.75, 95% CI = 3.67–16.38, P = 0.000) were independent predictors of recurrence.
ConclusionsCompared with traditional PTCSL, one-step multichannel PTCSL was more efficient and effective in the treatment of bilateral hepatolithiasis.
相似文献In the UK, it is common practice to obtain full-length femur radiographs in patients admitted with neck of femur fractures (NOF) and co-existing malignancy. Limited literature exists studying this topic. Our aim was to identify whether full-length femur radiographs are of diagnostic and therapeutic value in this demographic.
MethodsA retrospective observational analysis of the patients admitted with a neck of femur fracture over a 5-year period (2015–2020) using the National Hip Fracture Database was performed at a major trauma centre. Electronic patient records were accessed to screen the NOF patients who had co-existing malignancy and subsequently underwent a full-length femur radiograph. In addition to patient demographics, we also identified the plan and whether it was affected by findings of the full-length radiograph, the operation performed, any additional investigations undertaken for malignancy, the type of cancer, complications and 1-year mortality.
ResultsOf the 2416 patients screened, 18% had a co-existing malignancy (n = 431). Of the 431 with underlying malignancy, 424 patients underwent a full-length femur radiograph while only seven of these radiographs identified lesions. From the seven patients with findings of metastatic deposits on full-length radiographs, none required an alternative operation to that which they normally would undergo. Furthermore, no patients required a longer stem arthroplasty or longer internal fixation. One in four fractures was associated with co-existing breast malignancy (26.5%, n = 114), followed by prostate cancer (14.8%, n = 64). Colorectal, lung, bladder and skin (squamous cell carcinoma) contributed 6–10% (n = 44, 40, 33, 29, respectively). Other malignancies contributed to the rest of the 25%.
ConclusionTo conclude, full-length radiographs had no diagnostic or therapeutic value in our cohort of patients regardless of the full-length femur findings.
相似文献Recent studies suggest that FGFR3 is a potential therapeutic target in urothelial carcinoma (UC). The purpose of this study was to evaluate the rates and types of FGFR3 aberrations in patients with muscle-invasive UC who received radical resection.
MethodsWe analyzed surgical tumor samples from 74 UC patients who had received radical cystectomy (n = 40) or ureteronephrectomy (n = 34). Ion AmpliSeq Cancer Hotspot Panel v2 and nCounter Copy Number Variation Assay were used to detect FGFR3 aberrations.
ResultsFifty-four patients (73%) had high-grade tumors, and 62% had lymph node involvement. Sixteen patients (22%) harbored FGFR3 alterations, the most common of which was FGFR3 mutations (n = 13): Y373C (n = 3), N532D (n = 3), R248C (n = 2), S249C (n = 1), G370C (n = 1), S657S (n = 1), A797P (n = 1), and 746_747insG (n = 1). Three additional patients had a FGFR3-TACC3 rearrangement. The frequency of FGFR3 aberrations was higher in bladder UC (25%) than in UC of the renal pelvis and ureter (18%) but the difference was not statistically significant (P = 0.444). Genes that were co-aberrant with FGFR3 included APC (88%), PDGFRA (81%), RET (69%), and TP53 (69%).
ConclusionsWe report the frequency and types of FGFR3 aberrations in Korean patients with UC. Patients with FGFR3 mutations or FGFR3-TACC3 fusion may constitute potential candidates for a novel FGFR-targeted therapy in the perioperative setting.
相似文献To compare high- versus low-viscosity bone cement on the clinical outcomes and complications in patients with Osteoporotic vertebral compression fractures (OVCFs) who underwent percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP).
MethodsPubMed, Embase, and the Cochrane Library were searched for papers published from inception up to February 2021 for potentially eligible studies comparing high- versus low-viscosity cement for PVP/PKP. The outcomes were the leakage rate, visual analog scale (VAS), and Oswestry Disability Index (ODI).
ResultsEight studies (558 patients; 279 in each group) were included. The meta-analysis showed that the leakage rate was lower with high-viscosity cement than with low-viscosity cement (OR = 0.23, 95%CI 0.14–0.39, P < 0.001; I2 = 43.5%, Pheterogeneity = 0.088); similar results were observed specifically for the disk space, paravertebral space, and peripheral vein, but there were no differences regarding the epidural space and intraspinal space. The VAS was decreased more significantly with high-viscosity cement than with low-viscosity cement (WMD = − 0.21, 95%CI − 0.38, − 0.04, P = 0.015; I2 = 0.0%, Pheterogeneity = 0.565). Regarding the ODI, there was no difference between high- and low-viscosity cement (WMD = − 0.88, 95%CI − 3.06, 1.29, P = 0.426; I2 = 78.3%, Pheterogeneity < 0.001).
ConclusionsThere were lower cement leakage rates in PVP/PKP with high-viscosity bone cement than low-viscosity bone cement. The two groups have similar results in ODI, but the VAS scores favor high-viscosity bone cement. Therefore, the administration of high-viscosity bone cement in PVP/ PKP could be a potential option for improving the complications of leakage in OVCFs, while the clinical efficacy of relieving pain is not certain.
相似文献The aim of this study was to assess safety and efficacy of vertebral body stenting (VBS) by analyzing (1) radiographic outcome, (2) clinical outcome, and (3) perioperative complications in patients with vertebral compression fractures treated with VBS at minimum 6-month follow-up.
MethodsIn this retrospective cohort study, 78 patients (61 ± 14 [21–90] years; 67% female) who have received a vertebral body stent due to a traumatic, osteoporotic or metastatic thoracolumbar compression fracture at our hospital between 2012 and 2020 were included. Median follow-up was 0.9 years with a minimum follow-up of 6 months. Radiographic and clinical outcome was analyzed directly, 6 weeks, 12 weeks, 6 months postoperatively, and at last follow-up.
ResultsAnterior vertebral body height of all patients improved significantly by mean 6.2 ± 4.8 mm directly postoperatively (p < 0.0001) and remained at 4.3 ± 5.1 mm at last follow-up compared to preoperatively (p < 0.0001). The fracture kyphosis angle of all patients improved significantly by mean 5.8 ± 6.9 degrees directly postoperatively (p < 0.0001) and remained at mean 4.9 ± 6.9 degrees at last follow-up compared to preoperatively (p < 0.0001). The segmental kyphosis angle of all patients improved significantly by mean 7.1 ± 7.6 degrees directly postoperatively (p < 0.0001) and remained at mean 2.8 ± 7.8 degrees at last follow-up compared to preoperatively (p = 0.03). Back pain was ameliorated from a preoperative median Numeric Rating Scale value of 6.5 to 3.0 directly postoperatively and further bettered to 1.0 six months postoperatively (p = 0.0001). Revision surgery was required in one patient after 0.4 years.
ConclusionVertebral body stenting is a safe and effective treatment option for osteoporotic, traumatic and metastatic compression fractures.
相似文献In the USA, most patients with clinical stage II/III rectal cancer receive neoadjuvant chemoradiation (chemo/XRT) over 5–6 weeks followed by a 6–10-week break before proctectomy. As chemotherapy is delivered at radio-sensitizing doses, there is essentially a 3-month window during which potential systemic disease is untreated. Evidence regarding the utility of restaging patients prior to proctectomy is limited.
MethodsPubMed, Scopus, Web of Science, and the Cochrane Library were searched for studies evaluating the utility of restaging patients with rectal cancer after completion of long-course chemo/XRT, and reporting associated changes in management. Studies that were non-English, included <50 patients, or examining the diagnostic accuracy of imaging modalities were excluded. Study quality was evaluated using the modified Newcastle Ottawa Scale.
ResultsEight studies were identified including a total of 1251 patients restaged between completion of chemo/XRT and proctectomy. All studies were retrospective. Restaging identified new metastatic disease in 72 (6.0%) patients, with 4 studies reporting specific sites: liver (n = 28), lung (n = 8), adrenal (n = 1), bone (n = 1), and multiple sites (n = 7). Overall progression (distant or local) was detected in 88 (7.0%) patients and resulted in a change in management in 77 (87.5%) of these patients. Tumor-related prognostic characteristics were inconsistently reported among studies, precluding meta-analysis.
ConclusionsAlthough restaging between completion of neoadjuvant chemo/XRT and proctectomy detects disease progression in only a small percentage of patients, findings alter the treatment plan in the vast majority of these patients. Multi-institutional collaboration with analysis of well-defined prognostic variables may better identify patients most likely to benefit from restaging.
相似文献Traumatic thoracolumbar (TL) fractures are the most common vertebral fractures. Although a consensus on the preferred treatment is missing, percutaneous pedicle screw fixation (PPSF) has been progressively accepted as treatment option, since it is related to lower soft tissues surgical-injury and perioperative complications rate. This study aims to evaluate the long-term clinical–radiological outcomes after PPSF for TL fractures at a single tertiary academic hospital.
MethodsThis is a retrospective cohort study. Back pain was obtained at preoperative, postoperative and final follow-up using Visual Analog Scale. Patient-reported outcomes, the Oswestry Disability Index and the 36-Item Short Form, were obtained to asses disability during follow-up. Radiological measures included Cobb angle, mid-sagittal index, sagittal index (SI) and vertebral body height loss. A multivariate regression analysis on preoperative radiological features was performed to investigate independent risk factors for implant failure.
ResultsA total of 296 patients with 368 TL fractures met inclusion criteria. Mean follow-up was 124.3 months. The clinical and radiological parameters significantly improved from preoperative to last follow-up measurements. The multivariate analysis showed that Cobb angle (OR = 1.3, p < 0.001), SI (OR = 1.5, p < 0.001) and number of fractures (OR = 1.1, p = 0.05), were independent risk factors for implant failure. The overall complication rate was 5.1%, while the reoperation rate for implant failure was 3.4%.
ConclusionsIn our case series, PPSF for TL injuries demonstrated good long-term clinical-radiological outcomes, along with low complication and reoperation rates. Accordingly, PPSF could be considered as a valuable treatment option for neurologically intact patients with TL fractures. Additionally, in this cohort, number of fractures ≥ 2, Cobb angle ≥ 15° and sagittal index ≥ 21° were independent risk factors for implant failure.
相似文献Clinical guidelines recommend epidural steroid injection (ESI) as a treatment option for severe disc-related sciatica, but there is considerable uncertainty about its effectiveness. Currently, we know very little about factors that might be associated with good or poor outcomes from ESI. The aim of this systematic review was to synthesise and appraise the evidence investigating prognostic factors associated with outcomes following ESI for patients with imaging confirmed disc-related sciatica.
MethodsThe search strategy involved the electronic databases Medline, Embase, CINAHL Plus, PsycINFO and reference lists of eligible studies. Selected papers were quality appraised independently by two reviewers using the Quality in Prognosis Studies tool. Between-study heterogeneity precluded statistical pooling of results.
Results3094 citations were identified; 15 studies were eligible. Overall study quality was low with all judged to have moderate or high risk of bias. Forty-two prognostic factors were identified but were measured inconsistently. The most commonly assessed prognostic factors were related to pain and function (n = 10 studies), imaging features (n = 8 studies), patient socio-demographics (n = 7 studies), health and lifestyle (n = 6 studies), clinical assessment findings (n = 4 studies) and injection level (n = 4 studies). No prognostic factor was found to be consistently associated with outcomes following ESI. Most studies found no association or results that conflicted with other studies.
ConclusionsThere is little, and low quality, evidence to guide practice in terms of factors that predict outcomes in patients following ESI for disc-related sciatica. The results can help inform some of the decisions about potential prognostic factors that should be assessed in future well-designed prospective cohort studies.
相似文献This updated meta-analysis aimed to compare single and dual growing rods, including both traditional growing rod and magnetically controlled growing rod (MCGR) used in the treatment of early-onset scoliosis (EOS) with regard to deformity correction, spinal growth, and complications.
MethodsThis meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using articles extracted from PubMed, EMBASE databases, and Cochrane Library databases. Only articles reporting the complications and the imaging parameters before and after growing rods in the patients diagnosed with EOS were included. We extracted and statistically analyzed the data deemed relevant for this study, and used the Newcastle–Ottawa Scale to assess the risk of bias in each study. Data synthesis and statistical analyses were performed using R software.
ResultsFifteen eligible articles containing 409 participants (n = 185, single growing rods; n = 224, dual growing rods) were identified. The meta-analysis found no significant differences in the preoperative and postoperative major Cobb angle, T1–S1 distance, thoracic kyphosis, and coronal balance between single and dual rods groups. The final follow-up major Cobb angle (P = 0.01; standardized mean difference, − 0.42 [95% confidence interval (CI), − 0.74 to − 0.10]; I2 = 23%) was significantly smaller in dual rods group than single-rod group. However, no significant differences in the correction rate of angle (major Cobb angle and kyphosis angle) and changes in the T1–S1 distance between the two groups were observed. Moreover, there were no significant differences in the metalwork failure, infection, or proximal junctional kyphosis between single and dual rods groups. However, total complications (P = 0.03; risk ratio (RR), 0.79 [95% CI, 0.63–0.98]; I2 = 29%) and distraction failure in MCGR (P = 0.04; RR, 0.38 [95% CI, 0.14–0.98]; I2 = 11%) were significantly lower in dual rods group than single-rod group.
ConclusionThis updated meta-analysis found that patients with dual growing rods had fewer complications, especially distraction failure in MCGR, than those with single growing rod. However, none of deformity correction, spinal growth, or other complications differed between single and dual growing rods. Therefore, we believe that dual growing rods do not provide strong advantages over single growing rod in the treatment of EOS.
相似文献Both erector spinae plane block and wound infiltration are used to improve analgesia following spinal fusion surgery. Herein, we compared the analgesic effect of bilateral erector spinae plane block with wound infiltration in this patient population.
MethodsIn this randomized trial, 60 patients scheduled for elective open posterior lumbar interbody fusion surgery were randomized to receive either ultrasound-guided bilateral erector spinae plane block before incision (n = 30) or wound infiltration at the end of surgery (n = 30). Both groups received standardized general anesthesia and postoperative analgesia, including patient-controlled analgesia with sufentanil and no background infusion. Opioid consumption and pain intensity were assessed at 2, 6, 12, 24, and 48 h after surgery. The primary outcome was cumulative opioid consumption within 24 h after surgery.
ResultsAll 60 patients were included in the intention-to-treat analysis. The equivalent dose of sufentanil consumption within 24 h was significantly lower in patients given erector spinae plane block (median 11 μg, interquartile range 5–16) than in those given wound infiltration (20 μg, 10 to 43; median difference − 10 μg, 95% CI − 18 to − 3, P = 0.007). The cumulative number of demanded PCA boluses was significantly lower with erector spinae plane block at 6 h (median difference − 2, 95% CI − 3 to 0, P = 0.006), 12 h (− 3, 95% CI − 6 to − 1, P = 0.002), and 24 h (− 5, 95% CI − 8 to − 2, P = 0.005) postoperatively. The proportion given rescue analgesia was also significantly lower in patients given erector spinae plane block group within 48 h (relative risk 0.27, 95% CI 0.07 to 0.96, P = 0.037). There were no statistical differences in pain intensity at any timepoints between groups. No procedure-related adverse events occurred.
ConclusionsCompared with wound infiltration, bilateral ultrasound-guided erector spinae plane block decreases short-term opioid consumption while providing similar analgesia in patients following lumbar spinal fusion surgery.

相似文献There is an increasing incidence of elderly patients requiring emergency laparotomy. Our study compares the outcomes of elderly patients undergoing emergency laparotomy against the outcomes of non-elderly patients.
MethodologyPatients who underwent emergency laparotomy between 2015 and 2017 from the National University Hospital, Singapore, were included. Apart from demographic data, indication of surgery and surgical procedure performed were collected. Prospectively collected nutritional scores were evaluated. Outcome measures included duration of surgery, length of ICU and total hospital stay, post-operative complications, and mortality indices. We performed multivariate Cox regression analysis to determine the contribution of various risk factors towards overall survival following emergency laparotomy.
ResultsA total of 170 emergency laparotomies were performed. Compared to non-elderly patients, elderly patients had a significantly longer mean stay in hospital (31.5 vs. 18.6 days, p = 0.006) and mean stay in ICU (13.1 vs. 5.3 days, p = 0.003). More elderly patients suffered from post-laparotomy complications compared with non-elderly patients (65.8% vs. 37.4%, p < 0.001). 30-day mortality (31.5% vs. 8.8%, p = 0.019) and 1-year mortality (27.9% vs. 14.3%, p = 0.023) were higher in elderly patients compared with non-elderly patients. Interestingly, there was no statistically significant difference between elderly and non-elderly groups in both the global 3-MinNS as well as the global SGA nutritional scores. ASA status (HR 2.61, 95% CI 1.05–6.45, p = 0.038) was an independent risk factor for decreased survival following emergency laparotomy. Notably, while age ≥ 65 demonstrated a significant correlation with survival on univariate analysis (HR 1.03 (1.01–1.05), p = 0.003), this effect was lost following multivariate regression (HR 1.01 (0.453–2.23), p = 0.989).
ConclusionElderly patients suffer worse morbidity and mortality following emergency laparotomy. This is likely contributed by comorbidities resulting in higher ASA status.
相似文献With the improvement in diagnostic imaging, perioperative care and surgical technique, the indications and complexity of liver resections have developed. However, the surgical indications remain controversial especially for some complex or advanced hepatocellular carcinomas. This study was designed to evaluate the concordance between hepatectomy recommendations proposed by Watson for Oncology, a cognitive technology providing decision support, and those determined by surgeons in our center for patients with hepatocellular carcinoma.
MethodsWe retrospectively reviewed 243 patients with hepatocellular carcinoma who were recommended for surgical treatment and received hepatectomy between 2008 and 2016 at the Zhujiang Hospital of Southern Medical University. Watson for Oncology classified the treatment options into three categories: recommended, for consideration and not recommended. Treatment recommendations were considered concordant if the hepatectomy recommendations were designated “recommended” or “for consideration” by Watson for Oncology. The factors potentially affecting concordance rate were also analyzed in our study.
ResultsThe hepatectomy recommendations of 174 patients were concordant. There were significant differences in the coincidence rate between concordant group and discordant group considering tumor numbers (P = 0.006), extension of hepatectomy (P = 0.009) and BCLC staging system (P < 0.001). Lower degrees of concordance were observed in patients with multiple tumors, major hepatectomy and portal hypertension by using logistic regression analysis (OR = 0.309, P = 0.004; OR = 0.384, P = 0.004; and OR = 0.376, P = 0.022, respectively).
ConclusionThe concordance between Watson for Oncology and surgeons’ hepatectomy recommendation for hepatocellular carcinoma was only 72%. Differences in practice patterns for HCC between the USA (where Watson for Oncology was calibrated) and China may be the major cause of discordance. Watson for Oncology still requires further improvement and localization to be widely applied in China.
相似文献Snake envenomation is associated with major morbidity especially in low- and middle-income countries and may require fasciotomy. We determined patient factors associated with the need for fasciotomy after venomous snake bites in children located in KwaZulu-Natal, South Africa.
MethodsSingle institutional review of historical data (2012–2017) for children (<18 years) sustaining snake envenomation was performed. Clinical data, management, and outcomes were abstracted. Syndromes after snake bite were classified according to Blaylock nomenclature: progressive painful swelling (PPS), progressive weakness (PW), or bleeding (B), as it is difficult to reliably identify the species of snake after a bite. Comparative and multivariable analyses to determine factors associated with fasciotomy were performed.
ResultsThere were 72 children; mean age was 7 (±3) years, 59% male. Feet were most commonly affected (n = 27, 38%) followed by legs (n = 18, 25%). Syndromes (according to Blaylock) included PPS (n = 63, 88%), PW (n = 5, 7%), and B (n = 4, 5%). Eighteen patients underwent fasciotomy, and one required above knee amputation. Nine patients received anti-venom. Few patients (15%) received prophylactic beta-lactam antibiotics. Hemoglobin < 11 mg/dL, leukocytosis, INR >1.2, and age-adjusted shock index were associated with fasciotomy. On regression, age-adjusted shock index and hemoglobin concentration < 11 mg/dL, presentation >24 h after snake bite, and INR >1.2 were independently associated with fasciotomy. Model sensitivity was 0.89 and demonstrated good fit.
ConclusionsPatient factors were associated with the fasciotomy. These factors, coupled with clinical examination, may identify those who need early operative intervention. Improving time to treatment and the appropriate administration of anti-venom will minimize the need for surgery.

相似文献As complete prevention of postoperative pancreatic fistula (POPF) after pancreatic surgery remains difficult, many risk factors for clinically relevant POPF (CR-POPF) have been reported. However, their clinical impact could be limited because all previous reports included patients without biochemical leakage (BL) that rarely developed to CR-POPF. Therefore, a new strategy for identifying high-risk patients who develop delayed complications from patients with confirmed BL and for implementing interventions for such patients in the early postoperative period is required. This study aimed to examine the role of fistulography in predicting CR-POPF from confirmed BL.
MethodsConsecutive patients diagnosed with BL on postoperative day 3 after pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) from January 2013 to June 2015 in our institution were included. Fistulography was performed 1 week after the operation, and the associations between findings on fistulography and delayed complications associated with POPF were evaluated.
ResultsEighty-four (37%) of 227 patients who underwent PD and 45 (48%) of 94 patients who underwent DP were included and divided to two groups according to fistulographic findings (simple type, n = 107, 83%; cavity type, n = 22, 17%). The latter finding was associated with a greater morbidity rate (Clavien–Dindo grade ≥ 2: 36% vs 59%, p = 0.018) and a worse final POPF grade (B/C 64% vs 95%, p = 0.003). In the multivariate analysis, cavity type on fistulography was a significant predictive factor for grade B/C POPF.
ConclusionsFistulography is a useful examination for identifying patients with a high risk of developing delayed complications associated with POPF.
相似文献Opioids are the primary analgesics used in patients undergoing spine surgery. Postoperative pain is common despite their liberal use and so are opioid-associated side effects. Non-opioid analgesics are gaining popularity as alternative to opioids in spine surgery.
MethodsThis systematic review evaluated current evidence regarding opioid and non-opioid intraoperative analgesia and their influence on immediate postoperative pain and adverse events in spine surgery.
ResultsA total of 10,459 records were obtained by searching Medline, EMBASE and Web of Science databases and six randomized controlled trials were included. Differences in postoperative pain scores between opioid and non-opioid groups were not significant at 1 h: 4 studies, mean difference (MD) = 0.65 units, 95% confidence intervals (CI) [−0.12 to 1.41], p = 0.10, but favored non-opioid at 24 h after surgery: 3 studies, MD = 0.75 units, 95%CI [0.03 to 1.46], p = 0.04. The time for first postoperative analgesic requirement was shorter (MD = −45.06 min, 95%CI [−72.50 to −17.62], p = 0.001), and morphine consumption during first 24 h after surgery was higher in opioid compared to non-opioid group (MD = 4.54 mg, 95%CI [3.26 to 5.82], p < 0.00001). Adverse effects of postoperative nausea and vomiting (Relative risk (RR) = 2.15, 95%CI [1.37 to 3.38], p = 0.0009) and shivering (RR = 2.52, 95%CI [1.08 to 5.89], p = 0.03) were higher and bradycardia was lower (RR = 0.35, 95%CI [0.17 to 0.71], p = 0.004) with opioid analgesia.
ConclusionThe certainty of evidence on GRADE assessment is low for studied outcomes. Available evidence supports intraoperative non-opioid analgesia for overall postoperative pain outcomes in spine surgery. More research is needed to find the best drug combination and dosing regimen.

相似文献Hungry bone syndrome is characterized by prolonged and severe hypocalcemia following parathyroidectomy. Previously, we reported that preoperative alkaline phosphatase is a major factor predicting prolonged hospital stay. Nonetheless, some patients with low alkaline phosphatase levels presented with hungry bone syndrome, suggesting that additional factors may play a role.
MethodsFrom September 2010 to December 2017, consecutive dialysis patients who underwent parathyroidectomy for secondary hyperparathyroidism were analyzed. Length of hospital stay was used as a surrogate marker for postoperative bone hunger.
ResultsA total of 260 patients were included in the study. The median postoperative hospital stay was 3 days, and 69 (27%) patients had a stay longer than 3 days. Multivariate logistic regression analysis revealed that alkaline phosphatase (odds ratio [OR] = 1.005), osteocalcin (OR = 1.001), and subtotal parathyroidectomy (OR = 0.061) were associated with prolonged hospital stay. Multivariate linear regression analysis indicated that age (β = − 0.170), alkaline phosphatase (β = 0.430), and osteocalcin (β = 0.166) were correlated with the length of stay. After surgery, the median osteocalcin level increased from 264 to 478 ng/mL (P < 0.001).
ConclusionsAlkaline phosphatase is the main predictor of hungry bone syndrome after parathyroidectomy, and preoperative osteocalcin is an additional independent predictor. Patients with a high osteocalcin level may prone to have a higher demand for calcium supplementation.
