AbstractThe presence of postoperative complications may have a significant impact on the outcome of the breast reconstruction. The aim of this study was to investigate early postoperative complications and the risk factors for their occurrence. A prospective analysis was carried out to evaluate surgical outcomes after breast reconstructive surgeries performed over a 2-year period. Procedures included expander/implant (TE/IMP), pedicle transverse rectus abdominis musculocutaneous (pTRAM), and latissimus dorsi (LD) techniques. All adverse events which occurred within 6 weeks of surgery were ranked according to severity based on the contracted Accordion grading system. Outcomes were assessed for their association with surgical, demographic, and clinical variables. Sixty-one consecutive breast reconstruction procedures were analyzed. The overall complication rate was 60.7% (n = 37), and 8 patients (13.1%) required reoperation. The lowest complication rate was observed in implant-based reconstructions (TE/IMP, 18.8%; pTRAM, 72.7%; LD, 78.3%; p = 0.008). Mild complications occurred significantly more often after LD reconstructions (LD, 60.9%; pTRAM, 22.7%; TE/IMP, 12.5%; p = 0.031), while severe complications were significantly more frequent after the pTRAM procedures (pTRAM, 27.3%; TE/IMP, 6.2%; LD, 8.7%; p = 0.047). Severe complications were associated with higher rehospitalization rate (p = 0.010) and longer hospital stay. Study revealed a significant impact of the operative method on the incidence and severity of early complications after breast reconstruction procedures with little effect from other demographic and clinical factors.

Abstract Background Postoperative complications are not rare in the elderly population after hepatectomy. However, predicting postoperative risk in elderly patients undergoing hepatectomy is not easy. We aimed to develop a new preoperative evaluation method to predict postoperative complications in patients above 65 years of age using biological impedance analysis (BIA). Methods Clinical data of 59 consecutive patients (aged 65 years or older) who underwent hepatectomy at our institution between 2017 and 2020 were retrospectively analyzed. Risk factors for postoperative complications (Clavien-Dindo ≥ III) were evaluated using multivariate regression analysis. Additionally, a new preoperative risk score was developed for predicting postoperative complications. Results Fifteen patients (25.4%) had postoperative complications, with biliary fistula being the most common complication. Abnormal skeletal muscle mass index from BIA and type of surgical procedure were found to be independent risk factors in the multivariate analysis. These two variables and preoperative serum albumin levels were used for developing the risk score. The postoperative complication rate was 0.0% with a risk score of ≤ 1 and 57.1% with a risk score of ≥ 4. The area under the receiver operating characteristic curve of the risk score was 0.810 (p = 0.001), which was better than that of other known surgical risk indexes. Conclusion Decreased skeletal muscle and the type of surgical procedure for hepatectomy were independent risk factors for postoperative complications after elective hepatectomy in elderly patients. The new preoperative risk score is simple, easy to perform, and will help in the detection of high-risk elderly patients undergoing elective hepatectomy.

Risk Factors For Survival

Abstract Purpose The incidence of intrahepatic cholangiocarcinoma is increasing worldwide. Despite advances in surgical and non-surgical treatment, reported outcomes are still poor and surgical resection remains to be the only chance for long-term survival of affected patients. The identification and validation of prognostic factors and scores, such as the recently introduced resection severity index, for postoperative morbidity and mortality are essential to facilitate optimal therapeutic regimens. Methods This is a retrospective analysis of 269 patients undergoing resection of histologically confirmed intrahepatic cholangiocarcinoma between February 1996 and September 2018 at a tertiary referral center for hepatobiliary surgery. Regression analyses were performed to evaluate potential prognostic factors, including the resection severity index. Results Median postoperative follow-up time was 22.93 (0.10–234.39) months. Severe postoperative complications (≥ Clavien-Dindo grade III) were observed in 94 (34.9%) patients. The body mass index (p = 0.035), the resection severity index (ASAT in U/l divided by Quick in % multiplied by the extent of liver resection graded in points; p = 0.006), additional hilar bile duct resection (p = 0.005), and number of packed red blood cells transfused during operation (p = 0.036) were independent risk factors for the onset of severe postoperative complications. Median Kaplan-Meier survival after resection was 27.63 months. Preoperative leukocytosis (p = 0.003), the resection severity index (p = 0.005), multivisceral resection (p = 0.001), and T stage ≥ 3 (p = 0.013) were identified as independent risk factors for survival. Conclusion Preoperative leukocytosis and the resection severity index are useful variables for preoperative risk stratification since they were identified as significant predictors for postoperative morbidity and mortality, respectively.

The Impact

446 Background: We investigated the impact of postoperative complications on pancreatic cancer survival and recurrence after curative surgery. Methods: This study included 164 patients who underwent curative surgery for pancreatic cancer between 2005 and 2014. The patients were classified into those with postoperative complications (C group) and those without postoperative complications (NC group). The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. Results: Postoperative complications were found in 61 of the 164 patients (37.2%). The RFS rate at five years after surgery was 10.6% in the C group patients and was 21.0% in the NC group patients. The RFS tended to be worse in the C group than in the NC group (p=0.1756). The OS rate at five years after surgery was 7.4% in the C group and 22.8% in the NC group, which was significantly different (p=0.0189). The multivariate analysis demonstrated that postoperative complications and lymphatic invasion were significant independent risk factors for the RFS and OS. Conclusions: The development of postoperative complications was a risk factor for a decreased overall survival and for disease recurrence in patients who underwent curative surgery for pancreatic cancer. The surgical procedure, perioperative care and the surgical strategy should be carefully planned to avoid complications.

Abstract Background Ankle fractures are common operative indications in orthopedic surgery. Their incidence is increasing. Objectives To identify independent risk factors and to develop prognostic models for the prediction of prolonged length of hospital stay (LOS) and the onset of postoperative complications. Materials and Methods This is a single-center, retrospective, observational study analyzing data of 154 consecutive, isolated, surgically treated ankle fractures. Multivariate binary logistic regression analysis was applied to identify significant independent risk factors. The validity and clinical applicability of the developed prognostic models was assessed with ROC-curve analysis (ROC: Receiver Operating Characteristic). Internal validation of prognostic models was performed with randomized backwards bootstrapping. Results The median LOS was 7 days. 50 patients (33%) had a longer LOS. 13% of operated patients had a postoperative complication (n = 20). Independent preoperative risk factors for prolonged length of stay were leukocytosis (p = 0.020; OR: 1.211), an increased CRP-level (p = 0.005; OR: 1.901), as well as a bi- (p = 0.002; OR: 15.197) or trimalleolar (p = 0.001; OR: 10.678) fracture type. Immediate operative therapy was an independent beneficial factor (p < 0.001; OR: 0.070). The onset of complications was associated significantly with diabetes mellitus (p = 0.004; OR: 9.903) and an elevated ASA score (p = 0,004; OR: 3.574). The developed prognostic models for the prediction of prolonged LOS (AUROC: 0.736) and postoperative complications (AUROC: 0.724) had a good clinical validity and were internally validated. Conclusion The current data pronounce the importance of preoperative laboratory works. Furthermore, co-morbidities play a major role in the prognosis of outcome. The developed prognostic models are able to reliably predict the outcome and enable the preoperative identification of high-risk patients.

Abstract Background To evaluate the efficacy and safety of surgical treatment of tuberculosis destroyed lung (TDL), and the influence of chronic pulmonary aspergillosis (CPA) on the outcomes of surgical treatment of TDL. Methods We performed a retrospective analysis of 113 patients with TDL who underwent surgical treatment from January 2005 to December 2019. Among them, 30 of these cases were complicated with CPA. The patients were divided into two groups: TDL group and TDL + CPA group. We analyzed the effectiveness and safety of surgical treatment of TDL, and further compared the effectiveness and safety of surgical treatment of TDL with or withoutthe presence of CPA. Results The TDL + CPA group had a significantly higher age (P=0.003), symptoms of hemoptysis (P=0.000), and a higher proportion of patients with preoperative serum albumin <30 g/L (P=0.014) as compared with TDL group. For all enrolled patients, the incidence of severe postoperative complications was 12.4% (14/113) and the postoperative mortality within 30 days after discharge was 4.4% (5/113). 86.7% (98/113) of the patients recovered and discharged, the incidence of severe postoperative complications in the TDA + CPA group was higher than that of TDL group (23.3% vs 8.4%, P = 0.034), although there was no difference in mortality between the two groups (P = 1.000). A binary logistic regression analysis showed that the independent risk factors for severe postoperative complications were male (OR 25.24, 95% CI 2.31–275.64; P = 0.008) and age ≥ 40 years (OR 10.34, 95% CI 1.56–68.65; P = 0.016). Conclusion Surgical treatment for patients with TDL is effective with an acceptable mortality rate whether or not the disease is complicated with CPA. The independent risk factors identified for severe postoperative complications in patients with TDL were male and ≥ 40 years old. It implies that when treating patients with TDA + CPA, particular attention should be paid to these patients who have these independent risk factors to avoid a poor outcome.

Purpose: To determine the frequencies of complications and risk factors for complications following endovascular abdominal aortic aneurysm (AAA) repair (EVAR). Methods: Thirty-nine articles published between October 1995 and October 1999 in English, German, French, or Dutch were identified in electronic databases. All articles reported perioperative (30-day) complications on 2387 patients, while postoperative complications (>30 days) were reported on 1645 patients in 30 of 39 studies. Data were pooled and subjected to multivariable logistic regression analysis to identify risk factors for death, endoleak, rupture, conversion, and local and systemic complications. Effects of risk factors were expressed as odds ratios (OR) with 95% confidence interval (CI). Results: Mean follow-up was 13.9 months (range 4–29). The perioperative death rate (3.7%) was lower than postoperative mortality (5.0% per annum). The risks for both endoleak (13.1%) and conversion (5.0%) were higher in the perioperative period than postoperatively (5.4% and 1.4% per annum, respectively). Independent risk factors for perioperative complications were: general anesthesia (death: OR = 5.1, 95% CI 1.9–13.3); EVT graft (endoleak: OR = 3.0, 95% CI 1.3–7.0); female sex (rupture: OR = 2.8, 95% CI 1.4–5.8); hypertension (conversion: OR = 0.03, 95% CI 0.0–0.3); age >70 years (conversion: OR = 3.5, 95% CI 1.3–9.2); and team experience >30 patients (conversion: OR = 3.0, 95% CI 1.2–7.6). Independent risk factors for postoperative complications were: predischarge examination (death: OR = 0.2, 95% CI 0.0–0.7); follow-up 30 days after operation (death: OR = 0.3, 95% CI 0.1–1.0); and female sex (rupture: OR = 1.4, 95% CI 0.5–4.4; conversion: OR 6.8, 95% CI 2.0–23.4; and systemic complications: OR = 2.9, 95% CI 1.1–7.5). Conclusions: The risk of complications after EVAR is high, supporting the cautious use of EVAR. Both patient characteristics and procedural variables were independent risk factors for complications. To avoid the limitations of this study, the results of randomized clinical trials must determine if EVAR offers a safe and durable alternative to open AAA repair.

Abstract Background: By analyzing the risk factors of postoperative complications in elderly patients with hip replacement, We aimed to develop a nomogram model based on preoperative and intraoperative variables and verified the sensitivity and specificity for risk stratification of postoperative complications in elderly with total hip replacement patients.Methods: A total of 414 elderly patients who underwent surgical treatment for total hip replacement hospitalized at the Affiliated Hospital of Guangdong Medical University from March 1, 2017 to August 31, 2019 were included into this study. Univariate and multivariate logistic regression were conducted to identify independent risk factors of postoperative complication in the 414 patients. A nomogram was developed by R software and validated to predict the risk of postoperative complications.Results: Multivariate logistic regression analysis revealed that age (OR=1.05, 95%CI: 1.00-1.09) , renal failure(OR=0.90, 95% CI: 0.83～0.97) , Type2 diabetes (OR=1.05, 95% CI: 1.00～1.09) , ALB (OR=0.91, 95% CI: 0.83～0.99) were independent risk factors of postoperative complication in elderly patients with hip replacement (P＜0.05) . For validation of the nomogram, ROC curve revealed that the model predicting postoperative complication in elderly patients with hip replacement was the area under the curve of 0.8254(95% CI: 0.78～0.87) , the slope of the calibration plot was close to 1 and the model passed Hosmer-Lemeshow goodness of fit test (x2 = 10.16, P=0.4264), calibration in R Emax=0.176, Eavg=0.027, which all demonstrated that the model was of good accuracy. Conclusion: The nomogram predicting postoperative complications in patients with total hip replacement constructed based on age, type 2 diabetes, renal failure and ALB is of good discrimination and accuracy, which was of clinical significance.

Background: paediatric patients are vulnerable to blood loss and even a small loss of blood can be associated with severe shock. In emergency situations, a red blood cell (RBC) transfusion may become unavoidable, although it is associated with various risks. The aim of this trial was to identify independent risk factors for perioperative RBC transfusion in children undergoing surgery. Methods: to identify independent risk factors for perioperative RBC transfusion in children undergoing surgery and to access RBC transfusion rates and in-hospital outcomes (e.g., length of stay, mortality, and typical postoperative complication rates), a monocentric, retrospective, and observational study was conducted. Descriptive, univariate, and multivariate analyses were performed. Results: between 1 January 2010 and 31 December 2019, data from n = 14,248 cases were identified at the centre. Analysis revealed an RBC transfusion rate of 10.1% (n = 1439) in the entire cohort. The independent predictors of RBC transfusion were the presence of preoperative anaemia (p < 0.001; OR = 15.10 with preoperative anaemia and OR = 2.40 without preoperative anaemia), younger age (p < 0.001; ORs between 0.14 and 0.28 for children older than 0 years), female gender (p = 0.036; OR = 1.19 compared to male gender), certain types of surgery (e.g., neuro surgery (p < 0.001; OR = 10.14), vascular surgery (p < 0.001; OR = 9.93), cardiac surgery (p < 0.001; OR = 4.79), gynaecology (p = 0.014; OR = 3.64), visceral surgery (p < 0.001; OR = 2.48), and the presence of postoperative complications (e.g., sepsis (p < 0.001; OR = 10.16), respiratory dysfunction (p < 0.001; OR = 7.56), cardiovascular dysfunction (p < 0.001; OR = 4.68), neurological dysfunction (p = 0.029; OR = 1.77), and renal dysfunction (p < 0.001; OR = 16.17)). Conclusion: preoperative anaemia, younger age, female gender, certain types of surgery, and postoperative complications are independent predictors for RBC transfusion in children undergoing surgery. Future prospective studies are urgently required to identify, in detail, the potential risk factors and impact of RBC transfusion in children.
