BACKGROUND Due to the complexity and numerous comorbidities associated with Crohn’s disease(CD),the incidence of postoperative complications is high,significantly impacting the recovery and prognosis of patients.Consequently,additional stu-dies are required to precisely predict short-term major complications following intestinal resection(IR),aiding surgical decision-making and optimizing patient care.AIM To construct novel models based on machine learning(ML)to predict short-term major postoperative complications in patients with CD following IR.METHODS A retrospective analysis was performed on clinical data derived from a patient cohort that underwent IR for CD from January 2017 to December 2022.The study participants were randomly allocated to either a training cohort or a validation cohort.The logistic regression and random forest(RF)were applied to construct models in the training cohort,with model discrimination evaluated using the area under the curves(AUC).The validation cohort assessed the performance of the constructed models.RESULTS Out of the 259 patients encompassed in the study,5.0%encountered major postoperative complications(Clavien-Dindo≥III)within 30 d following IR for CD.The AUC for the logistic model was 0.916,significantly lower than the AUC of 0.965 for the RF model.The logistic model incorporated a preoperative CD activity index(CDAI)of≥220,a diminished preoperative serum albumin level,conversion to laparotomy surgery,and an extended operation time.A nomogram for the logistic model was plotted.Except for the surgical approach,the other three variables ranked among the top four important variables in the novel ML model.CONCLUSION Both the nomogram and RF exhibited good performance in predicting short-term major postoperative complic-ations in patients with CD,with the RF model showing more superiority.A preoperative CDAI of≥220,a di-minished preoperative serum albumin level,and an extended operation time might be the most crucial variables.The findings of this study can assist clinicians in identifying patients at a higher risk for complications and offering personalized perioperative management to enhance patient outcomes. 展开更多

AIM: To investigate the effectiveness of combinationtherapy with transzonular triamcinolone-moxifloxacin andconventional perioperative drops in reducing postoperativecomplications of cataract surgery. METHODS: Electronic medical records of cataractsurgery patients (single surgeon) were reviewed fromJanuary 2018 to September 2021. The rate of postoperativecomplications including prolonged and/or recurrentpostoperative inflammation, endophthalmitis, cystoid macularedema (CME), and intraocular pressure (IOP) was comparedbetween the patients receiving combinative therapy andpatients receiving drops only. RESULTS: Totally 596 patients and 1057 eyes(Combinative-Therapy group 493 and Drop-Only group 564)were included in this study. Using combination therapyreduced the relative risk of postoperative inflammationby 26.9% (16.6% Combinative-Therapy vs 22.7% Drop-Only, P=0.013). The incidence of endophthalmitis was 0in Combinative-Therapy group vs 0.5% in Drop-Only group(relative risk reduction 100%), although not statisticallysignificant (P=0.10). The incidence of severe IOP spikeswas not significantly different between Combinative-Therapy (2.4%) and Drop-Only (1.6%) groups (P=0.33).The relative risk of postoperative CME was 51.4% less inthree months follow up visit in Combinative-Therapy group,although not statistically significant (P=0.07). The visualoutcome 1-month postop. (best corrected visual acuity) wassignificantly better in Combinative-Therapy (logMAR 0.10)compared to Drop-Only (logMAR 0.14) groups (P=0.02) whilethe baseline visual acuity was not significantly different. CONCLUSION: The combinative approach oftranszonular triamcinolone-moxifloxacin plus perioperativeeyedrops is an effective method to minimize postoperativeinflammation, with better visual outcomes. It couldpotentially reduce the risk of postoperative endophthalmitisand CME (near-significant P-values;larger studies couldanalyze better considering low incidence). 展开更多

The routine introduction of novel anti-inflammatory therapies into the mana-gement algorithms of patients with Crohn’s disease over the last 2 decades has not substantially changed the likelihood of ultimate surgery.Rather it has delayed the operative need and altered the presentation phenotype.The prospect of complic-ations continues to remain high in this modern era but depending upon the cohort assessed,it remains difficult to make strict comparisons between individual spe-cialist centres.Those patients who present rather late after their diagnosis with a septic complication like an intra-abdominal abscess and a penetrating/fistulizing pattern of disease are more likely to have a complicated course particularly if they have clinical features such as difficult percutaneous access to the collection or multilocularity both of which can make preoperative drainage unsuccessful.Eq-ually,those cases with extensive adhesions where an initial laparoscopic approach needs open conversion and where there is an extended operative time,unsur-prisingly will suffer more significant complications that impact their length of hospital stay.The need for a protective stoma also introduces its own derivative costs,utilizing a range of health resources as well as resulting in important alte-rations in quality of life outcomes.Having established the parameters of the pro-blem can the statistical analysis of the available data identify high-risk cases,promote the notion of centralization of specialist services or improve the allo-cation of disease-specific health expenditure? 展开更多

Background: Thyroid diseases are among the leading endocrine disorders affecting a large proportion of people worldwide and show geographical variation in incidence and histopathological pattern related to age, sex, dietary and environmental factors. Histopathological patterns of surgically treated thyroid diseases play an important role in early diagnosis and management of these diseases. There is, however, limited published data regarding histopathological reports on thyroid disease in our local setting. This study aimed to determine the histopathological patterns and highlight early postoperative complications among patients with surgically treated thyroid diseases at Bugando Medical Centre (BMC). Methods: This was a longitudinal study involving all patients with surgically treated thyroid diseases seen at BMC over a period of 6 months from October 2019 to March 2020. Results: A total of 84 patients were studied. Females outnumbered males by a female to male ratio of 11:1. The median age of patients was 44 [IQR, 35 - 54] years old, the youngest was 14 years old and the oldest was 76 years old. Colloid goiter was the most common non-neoplastic lesion accounting for 34 (44.7%) patients. Among the neoplastic lesions, follicular adenoma was the most commonly encountered benign pathologies (n = 16;21.1%), while papillary carcinoma was the most commonly encountered malignancy (n = 4;50%). Following thyroidectomy, 12 (14.3%) patients developed early complications, of which hemorrhage sometimes requiring blood transfusion was the leading intra/postoperative complications accounting for 4 (33.3%) patients. Other complications include temporary recurrent laryngeal nerve palsy 2 (16.7%), surgical site infection 2 (16.7%) and tracheomalacia, bronchospasm, thyroid abscess and respiratory obstruction in 1 (8.3%) patient each, respectively. In this study, malignant thyroid lesion (p Conclusion: This study demonstrated that colloid goiter was the most common non-neoplastic lesion, and on the neoplastic category, follicular adenoma was the most common benign lesion, while papillary carcinoma was the most frequent malignant lesion. 展开更多

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. 展开更多

BACKGROUND Few studies have addressed the question of which drain types are more beneficial for patients with pancreatic trauma(PT).AIM To investigate whether sustained low negative pressure irrigation(NPI)suction drainage is superior to closed passive gravity(PG)drainage in PT patients.METHODS PT patients who underwent pancreatic surgery were enrolled consecutively at a referral trauma center from January 2009 to October 2021.The primary outcome was defined as the occurrence of severe complications(Clavien-Dindo grade≥Ⅲb).Multivariable logistic regression was used to model the primary outcome,and propensity score matching(PSM)was included in the regression-based sensitivity analysis.RESULTS In this study,146 patients underwent initial PG drainage,and 50 underwent initial NPI suction drainage.In the entire cohort,a multivariable logistic regression model showed that the adjusted risk for severe complications was decreased with NPI suction drainage[14/50(28.0%)vs 66/146(45.2%);odds ratio(OR),0.437;95%confidence interval(CI):0.203-0.940].After 1:1 PSM,44 matched pairs were identified.The proportion of each operative procedure performed for pancreatic injury-related and other intra-abdominal organ injury-related cases was comparable in the matched cohort.NPI suction drainage still showed a lower risk for severe complications[11/44(25.0%)vs 21/44(47.7%);OR,0.365;95%CI:0.148-0.901].A forest plot revealed that NPI suction drainage was associated with a lower risk of Clavien-Dindo severity in most subgroups.CONCLUSION This study,based on one of the largest PT populations in a single high-volume center,revealed that initial NPI suction drainage could be recommended as a safe and effective alternative for managing complex PT patients. 展开更多

AIM:To investigate the occurrence of postoperative complications of gastric cancer surgery,and analyze the potential causes of reoperation for early postoperative complications. METHODS:A total of 1639 patients who underwent radical or palliative gastrectomies for gastric cancer were included in the study.The study endpoint was the analysis of postoperative complications in inpatients. RESULTS:About 31%of patients had early postoperative complications,and complications of infection occurred most frequently.Intra-abdominal hemorrhage and anastomotic leak were the main causes of reoperation,which accounted for about 2.2%.Mortality was 11.1%in the reoperation group,but was only 0.8%in other patients.The duration of postoperative stay in hospital was significantly longer and the total expenditure was markedly higher in the patients who underwent reoperation(P<0.001).There was no significant association of any available factors in this study with the high rate of reoperation.CONCLUSION:Reoperation significantly increases the mortality rate and raises the burden of the surgical unit.More prospective studies are required to explore the potential risk factors. 展开更多

BACKGROUND: In spite of accurate selection of patients eligible for resection, and although advances in surgical techniques and perioperative management have greatly contributed to reducing the rate of perioperative deaths, stress must be placed on reducing the postoperative complication rates reported to be still as high as 50%. This study was designed to analyze the causes and foreseeable risk factors linked to postoperative morbidity on the grounds of data derived from a single-center surgical population. METHODS: From September 1989 to March 2005, 287 consecutive patients, affected either with HCC or liver metastasis, had liver resection at our department. Among the HCC series we recorded 98 patients (73.2%) in Child- Pugh class A, 32 (23.8%) in class B and 4 in class C (3%). In 104 colorectal metastases, 71% were due to colon cancer, 25% rectal, 3% sigmoid, and 1% anorectal. In 49 non-colorectal metastases, 22.4% were derived from breast cancer, 63.2% gastrointestinal tumors (excluding colon) and 14.4% other cancers. We performed 80 wedge resections, 77 bisegmentectomies and/or left lobectomies, 74 segmentectomies, 22 major hepatectomies, 20 left hepatectomies, and 14 trisegmentectomies. RESULTS: The in-hospital mortality rate in this series was 4.5%, and the morbidity rate was 47.7%, because of pleural effusion (30%), hepatic abscess (25%), hepatic insufficiency (19%), ascites (10%), hemoperitoneum (10%), or biliary fistula (6%). The variables associated with the technical aspects of the surgical procedure thatwere responsible for the complications were: a Pringle maneuver length more than 20 minutes (P=0.001); the type of liver resection procedure, including major hepatectomy (P=0.02), left hepatectomy (P=0.04), trisegmentectomy (P=0.04), bisegmentectomy and/or left lobectomy (P=0,04); and a blood transfusion of more than 600 ml (P=0.04). CONCLUSION: The evaluation of causes and foreseeable risk factors linked to postoperative morbidity during the planning of surgical treatment should play the same role as other factors weighed in the selection of patients eligible for liver resection. 展开更多

AIMTo identify simple and sensitive markers for postoperative complications after gastrectomy, the predictive values were compared among candidate preoperative factors.METHODSThree-hundred and twelve patients with previously untreated clinical T2-4 gastric cancer who underwent a D2 standard gastrectomy (distal gastrectomy or total gastrectomy) were included in the analysis. Correlations between 21 parameters that can be determined by preoperative routine blood tests and clinically relevant postoperative complications (grade II or higher according to the Clavien-Dindo classification) were evaluated. The optimal cutoff values and clinical significance of the selected markers were further evaluated by subgroup analyses according to age, body mass index, operative procedure and clinical disease stage.RESULTSSixty-six patients (21.1%) experienced grade II or higher postoperative complications. The platelet-lymphocyte ratio (PLR, total lymphocyte count/platelet count × 100) exhibited the highest area under the curve value (0.639) for predicting postoperative complications among the 21 parameters, and the optimal cutoff value was determined to be 0.71 (sensitivity = 70%, specificity = 56%). In the univariate analysis, the odds ratio of a low PLR for the occurrence of postoperative complications was 2.94 (95%CI: 1.66-5.35, P < 0.001), and a multivariate binomial logistic analysis involving other potential risk factors identified a low PLR as an independent risk factor for postoperative complications (OR = 3.32, 95%CI: 1.82-6.25, P < 0.001). In subgroups classified according to age, body mass index, operative procedure and clinical disease stage, the low PLR group exhibited an increased incidence of postoperative complications.CONCLUSIONThe preoperative PLR is a simple and useful predictor of complications after curative gastrectomy in patients with clinical T2-4 gastric cancer. 展开更多

AIM: To study the postoperative complications in patients with preoperative portal vein thrombosis (PVT) undergoing liver transplantation (LT) and to evaluate the complications with Doppler ultrasonography.METHODS: Retrospective studies were performed on 284 patients undergoing LT (286 LT) with respect to pre- and postoperative clinical data and Doppler ultrasonography. According to the presence and grade of preoperative PVT, 286 LTs were divided into three groups: complete PVT (c-PVT), partial PVT (p-PVT) and non-PVT, with 22, 30 and 234 LTs, respectively. Analyses were carried out to compare the incidence of early postoperative complications.RESULTS: PVT, inferior vena cava (IVC) thrombosis, hepatic artery thrombosis (HAT) and biliary complications were found postoperatively. All complications were detected by routine Doppler ultrasonography and diagnoses made by ultrasound were confirmed by clinical data or/and other imaging studies. Nine out of 286 LTs had postoperative PVT. The incidence of the c-Pv-r group was 22.7%, which was higher than that of the p-Pv-r group (3.3%, P 〈 0.05) and non- PVT group (1.3%, P 〈 0.005). No difference was found between the p-PVT and non-PVT groups (P 〉 0.25). Of the 9 cases with postoperative PVT, recanalizations were achieved in 7 cases after anticoagulation under the guidance of ultrasound, 1 case received portal vein thrombectomy and 1 case died of acute injection. Ten LTs had postoperative 1VC thrombosis. The c-PVT group had a higher incidence of IVC thrombosis than the non- PVT group (9.1% vs 2.6%, P 〈 0.05); no significant difference was found between either the c-PV-T and p-PVT groups (9.1% vs 6.7%, P 〉 0.5) or between the p-PVT and non-PVT groups (P 〉 0.25). Nine cases with IVC thrombosis were cured by anticoagulation under the guidance of ultrasound, and 1 case gained natural cure without any medical treatment after 2 mo. HAT was found in 2 non-PVT cases, giving a rate of 0.7% among 286 LTs. Biliary complications were seen in 12 LTs. The incidence of biliary complications in the c-PVT, p-PVT and non-PVT groups was 9.1%, 3.3% and 4.3%, respectively (P 〉 0.25 for all), among which 2 stenosis led retransplantations and others were controlled by relative therapy.CONCLUSION: C-PVT patients tend to have a higher incidence of PVT and IVC thrombosis than non- PVT patients after LT. The incidence of postoperative complications in p-PVT patients does not differ from that of non-PVT patients, A relatively low incidence of HAT was seen in our study, Doppler ultrasonography is a convenient and efficient method for detecting posttransplant complications and plays an important role in guiding treatment. 展开更多

BACKGROUND Carotid artery cross-clamping during carotid endarterectomy(CEA)may damage local cerebral perfusion and induce cerebral ischemia–reperfusion injury to activate local inflammatory responses.Neutrophil-to-lymphocyte ratio(NLR)is an indicator that reflects systemic inflammation.However,the correlation between NLR and complications after CEA remains unclear.AIM To investigate the association between NLR and major complications after surgery in patients undergoing CEA.METHODS This retrospective cohort study included patients who received CEA between January 2016 and July 2018 at Beijing Tiantan Hospital.Neutrophil and lymphocyte counts in whole blood within 24 h after CEA were collected.The primary outcome was the composite of major postoperative complications including neurological,pulmonary,cardiovascular and acute kidney injuries.The secondary outcomes included infections,fever,deep venous thrombosis,length of hospitalization and cost of hospitalization.Statistical analyses were performed using EmpowerStats software and R software.RESULTS A total of 224 patients who received CEA were screened for review and 206 were included in the statistical analyses;of whom,40(19.42%)developed major postoperative complications.NLR within 24 h after CEA was significantly correlated with major postoperative complications(P=0.026).After confounding factors were adjusted,the odds ratio was 1.15(95%CI:1.03–1.29,P=0.014).The incidence of major postoperative complications in the high NLR group was 8.47 times that in the low NLR group(P=0.002).CONCLUSION NLR is associated with major postoperative complications in patients undergoing CEA. 展开更多

Postoperative complications(PC)are a basic health outcome,but no surgery service in the world records and/or audits the PC associated with all the surgical procedures it performs.Most studies that have assessed the cost of PC suffer from poor quality and a lack of transparency and consistency.The payment system in place often rewards the volume of services provided rather than the quality of patients’clinical outcomes.Without a thorough registration of PC,the economic costs involved cannot be determined.An accurate,reliable appraisal would help identify areas for investment in order to reduce the incidence of PC,improve surgical results,and bring down the economic costs.This article describes how to quantify and classify PC using the Clavien-Dindo classification and the comprehensive complication index,discusses the perspectives from which economic evaluations are performed and the minimum postoperative follow-up established,and makes various recommendations.The availability of accurate and impartially audited data on PC will help reduce their incidence and bring down costs.Patients,the health authorities,and society as a whole are sure to benefit. 展开更多

AIM:To investigate the role of sex hormones in the early postoperative complications of gastrointestinal diseases. METHODS:A total of 65 patients who underwent operations for gastric and colorectal diseases(mainly malignant diseases)were included in the study. Peripheral venous blood samples were collected at different times for analysis of estradiol,testosterone and progesterone.The only study endpoint was analysis of postoperative complications. RESULTS:Patients of both sexes were uniform but postoperative complication rate was significantly higher in female patients(P=0.027).There was no significant association of estradiol and progesterone with postoperative complications.Testosterone levels in complicated patients were significantly lower than in uncomplicated patients(P<0.05).Area under the receiver operating characteristic curve showed that a lower value of testosterone was a predictor for higher complication rate(P<0.05),and a lower value oftestosterone at later times after surgery was a better predictor of complications. CONCLUSION:Patients with low testosterone level were prone to higher postoperative complications,which was evident in both sexes.However,further studies are necessary to support this result. 展开更多

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.AIM To develop a nomogram model 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),Type 2 diabetes(OR=1.05,95%CI:1.00-1.09),albumin(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,receive operating characteristic curve revealed that the model predicting postoperative complication in elderly patients with hipreplacement was the area under the curve of 0.8254 (95%CI: 0.78-0.87), the slope of the calibrationplot was close to 1 and the model passed Hosmer-Lemeshow goodness of fit test (χ^(2) = 10.16, P =0.4264), calibration in R E_(max) = 0.176, E_(avg) = 0.027, which all demonstrated that the model was ofgood accuracy.CONCLUSIONThe nomogram predicting postoperative complications in patients with total hip replacementconstructed based on age, type 2 diabetes, renal failure and ALB is of good discrimination andaccuracy, which was of clinical significance. 展开更多

BACKGROUND Fat embolism syndrome(FES)is a rare disease characterized by pulmonary distress,neurologic symptoms,and petechial rash and seriously threatens human life and health.It is still neglected clinically because of the lack of verifiable diagnostic criteria and atypical clinical symptoms.No studies on FES with pulmonary embolism(PE)and tympanic membrane perforation have been reported to date.Here,we report a rare case of concomitant FES,PE and tympanic membrane perforation after surgery in a patient with a tibiofibular fracture.CASE SUMMARY A 39-year-old man presented with right lower extremity pain due to a car accident while driving a motorbike on the road.X-ray and computed tomography scans revealed a fracture of the right mid-shaft tibia and proximal fibula categorized as a type A2 fracture according to the AO classification.A successful minimally invasive operation was performed 3 d after the injury.Postoperatively,the patient developed sudden symptoms of respiratory distress and hearing loss.Early diagnosis was made,and supportive treatments were used at the early stage of FES.Seven days after surgery,he presented a clear recovery from respiratory symptoms.The outcome of fracture healing was excellent,and his hearing of the left ear was mildly impaired at the last follow-up of 4 mo.CONCLUSION Concomitant FES,PE and tympanic membrane perforation are very rare but represent potentially fatal complications of trauma or orthopedic surgery and present with predominantly pulmonary symptoms.Early diagnosis and treatment can reduce the mortality of FES,and prevention is better than a cure. 展开更多

Objective: The aim of our study was to compare the risk of main postoperative complications of patients un- derwent total thyroidectomy (TT), near total thyroidectomy (NTT) and subtotal thyroidectomy (ST) for treating BMNG. Methods: Electronic databases including Cochrane Controlled Trials Register, EMbase, Medline, SCI Expanded-ISI, NTIS, SIGLE and CNKI were searched. Eligible studies were randomized controlled trials which compared the incidence of postoperative complications of TT with ST/NTT for treating BMNG. Data extraction was using predefined data fields and assessment of methodological quality with the GRADE approach. A ManteI-Haenszel random-effects model was used and the effect sizes were expressed by using relative risks and 95% confidence intervals. Results: Four studies including 881 participants that met inclusion criteria were analyzed. Compared with ST/NTT, TT was associated with increased risk of transient RLNI (recur- rent laryngeal nerve injuries) (relative risk 2.18, 95% confidence interval 1.08 to 4.42; P 〈 0.05) and transient hypocalcemia (3.79, 1.64 to 8.77; P 〈 0.05), but there were no statistically significant differences in permanent RLNI (1.36, 0.31 to 6.02; P 〉 0.05) and permanent hypocalcemia (2.37, 0.35 to 15.97; P 〉 0.05). The quality of evidence for each individual outcome was ultimately rated as moderate (permanent RLNI and permanent hypocalcemia), low (transient RLNI and transient hypocalce- mia). Conclusion: For treating BMNG with thyroidectomy, there were no statistically significant differences in postoperative complications between TT and ST/NTT on a long view. 展开更多
