Primary reperfusion in acute right ventricular infarction: An observational study简

AIM: To investigate the impact of primary reperfusion therapy (RT) on early and late mortality in acute right ventricular infarction (RVI).METHODS: RVI patients (n = 679) were prospectively classified as without right ventricular failure (RVF) (class A, n = 425, 64%), with RVF (class B, n = 158, 24%) or with cardiogenic shock (CS) (class C, n = 96, 12%). Of the 679 patients, 148 (21.7%) were considered to be eligible for thrombolytic therapy (TT) and 351 (51.6%) for primary percutaneous coronary intervention (PPCI). TIMI 3-flow by TT was achieved for A, B and C RVI class in 65%, 64% and 0%, respectively and with PPCI in 93%, 91% and 87%, respectively.RESULTS: For class A without RT, the mortality rate was 7.9%, with TT was reduced to 4.4% (P < 0.01) and with PPCI to 3.2% (P < 0.01). Considering TT vs PPCI, PPCI was superior (P < 0.05). For class B without RT the mortality was 27%, decreased to 13% with TT (P < 0.01) and to 8.3% with PPCI (P < 0.01). In a TT and PPCI comparison, PPCI was superior (P < 0.01). For class C without RT the in-hospital mortality was 80%, with TT was 100% and with PPCI, the rate decreased to 44% (P < 0.01). At 8 years, the mortality rate without RT for class A was 32%, for class B was 48% and for class C was 85%. When PPCI was successful, the long-term mortality was lower than previously reported for the 3 RVI classes (A: 21%, B: 38%, C: 70%; P < 0.001).CONCLUSION: PPCI is superior to TT and reduces short/long-term mortality for all RVI categories. RVI CS patients should be encouraged to undergo PPCI at a specialized center.     

POSSUM and p-POSSUM overestimate morbidity and mortality in laparoscopic bariatric surgery

BackgroundDespite their wide use in surgical audit, the application of the Physiologic and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM) and the Portsmouth predictor of mortality (p-POSSUM) in bariatric surgery has been limited. The aim of this study was to evaluate the usefulness of POSSUM and p-POSSUM in bariatric comparative audit.MethodsData were retrospectively collected on consecutive patients who underwent laparoscopic gastric by-pass (LRYGB) and sleeve gastrectomy (SG) at a teaching institute. POSSUM and p-POSSUM equations were applied. The observed to expected ratios for morbidity and mortality were calculated. A Student’s t test was performed to assess if a relationship could be found between the observed and the predicted outcomes.ResultsBetween 2008 and 2013, 504 patients (370 female) with a mean (range) age of 46 (17–69) years underwent LRYGB (n = 383) and SG (n = 121). The operative morbidity was 10.9% and mortality was .2%. POSSUM overpredicted morbidity (30.56%), and no relationship between morbidity risk and the development of complications was found (P = .152). There was a grouping of patients in the low-risk mortality groups for both POSSUM and p-POSSUM. Both equations overpredicted mortality (5.95% and 1.62%, respectively).ConclusionBoth POSSUM and p-POSSUM equations overpredicted morbidity and mortality in this only study in the literature of modern bariatric practice that employed a large representative patient sample receiving the commonest procedures. A multicenter study is needed to address the low incidence of events and enable modification of those equations for use in bariatric surgical audit.     

MatriDerm Decreases Donor Site Morbidity After Radial Forearm Free Flap Harvest in Transgender Surgery

BackgroundPhalloplasty with the radial forearm free flap is associated with a large donor site defect.AimTo compare two methods of donor site closure for functional and cosmetic long-term results: full-thickness skin grafting vs split-thickness skin grafting with MatriDerm.MethodsThirty-seven transgender patients had a neophallus created from a radial forearm free flap, and all were operated on by the same senior surgeon. Eight patients had their donor site defect closed by total skin grafting and 29 patients, operated on after 2009, received a split-thickness skin graft with MatriDerm closure. All 37 patients were evaluated by questionnaire and by careful clinical examination. Pressure perception was assessed with the Semmes-Weinstein monofilament test. Sensory recovery, skin quality, and cosmetic result also were compared. The contralateral arm was used as the control.OutcomesPressure perception values showed better sensory return in the MatriDerm group. Split-thickness skin grafting with MatriDerm achieved superior results in skin sensibility, superficial radial nerve recovery, and cosmetic aspect.ResultsOur findings support the hypothesis that MatriDerm can be used to preserve sensory function and decrease morbidity of the donor site.Clinical ImplicationsThe use of a dermal substitute decreases the morbidity of the forearm free flap donor site.Strengths and LimitationsThe strength of this study is its retrospective nature conducted of a prospectively maintained database of 37 consecutive radial forearm free flaps with superimposable dimensions and location performed by the same surgeon, thus limiting biases. A limitation is its small sample (particularly for the control group).ConclusionOur experience showed that the combination of a split-thickness skin graft with MatriDerm substantially decreases postoperative complications at the donor site defect on the forearm of transgender patients.Watfa W, di Summa PG, Meuli J, et al.

Incidence,consequences, and risk factors for anastomotic dehiscence after colorectal surgery: a prospective monocentric study

Background Anastomotic dehiscence is the most severe surgical complication after large bowel resection. This study was designed to assess the incidence, to observe the consequences, and to identify the risk factors associated with anastomotic leakage after colorectal surgery. Materials and methods All procedures involving anastomoses of the colon or the rectum, which were performed between November 2002 and February 2006 in a single institution, were prospectively entered into a computerized database. Results One thousand eighteen colorectal resections and 811 anastomoses were performed over this 40-month period. The most frequent procedures were sigmoid (276) and right colectomies (217). The overall anastomotic leak rate was 3.8%. The mortality rate associated with anastomotic leak was 12.9%. In univariate analysis, the following parameters were associated with an increased risk for anastomotic dehiscence: (1) ASA score ≥ 3 (p = 0.004), (2) prolonged (>3 h) operative time (p = 0.02), (3) rectal location of the disease (p < 0.001), (4) and a body mass index > 25 (p = 0.04). In multivariate analysis, ASA score ≥ 3 (OR = 2.5; 95% CI 1.5–4.3, p < 0.001), operative time > 3 h [OR = 3.0; 95% CI 1.1–8.0, p = 0.02), and rectal location of the disease (OR = 3.75; 95% CI 1.5–9.0 (vs left colon), p = 0.003; OR = 7.69; 95% CI 2.2–27.3 (vs right colon), p = 0.001] were factors significantly associated with a higher risk of anastomotic dehiscence. Conclusions Three risk factors for anastomotic leak have been identified, one is patient-related (ASA score), one is disease-related (rectal location), the third being surgery-related (prolonged operative time). These factors should be considered in perioperative decision-making regarding defunctioning stoma formation.     

Relation entre la dysfonction diastolique du ventricule gauche et la présence d’atteintes coronaires chez le sujet diabétique type 2

IntroductionType 2 diabetes is associated with an increased risk of coronary disease and is the leading cause of morbidity and mortality in this population. The main objective of our work is to study the correlation of diastolic function of the left ventricle with coronary disease in type 2 diabetics.Material and methodsAnalytical cross-sectional, monocentric prospective-looking study of 703 type 2 diabetic patients performed at the Military Regional Hospital of Constantine over a period of 04 years (2016-2019). We excluded 338 patients who did not receive coronary angiography; thus 365 patients are ultimately analyzed. Evaluation of diastolic function was performed by two-dimensional transthoracic echocardiography with the search of coronary disease. The data was analyzed using the Epi Info 7.2.1.0 with study of the relationship of the diastolic function to coronary disease by multiple logistic regression.ResultsThe average age of our final cohort is 57,7 ± 6,5 years, an average of 7.4 ± 1.8% of glycated hemoglobin, an average of 5,8 ± 4,1 years of diabetes, a sex ratio to 1.27. 49.3% had diastolic dysfunction. The prevalence of coronary disease is 32,9%. In multivariate analysis; diastolic dysfunction is correlated with coronary involvement significantly (OR = 2.02, _95% CI [1.50 - 2.90], p = 0.02).ConclusionThe prevalence of diastolic dysfunction is high in type 2 diabetics and is significantly correlated with coronary heart disease.     

Neonatal Morbidities Associated with Histologic Chorioamnionitis Defined Based on the Site and Extent of Inflammation in Very Low Birth Weight Infants

Conflicting results on the influences of histologic chorioamnionitis (HC) on neonatal morbidities might be partly originated from using different definition of HC. The aim of this study was to determine the relationship between HC and neonatal morbidities using definition of HC that reflects the site and extent of inflammation. This was a retrospective cohort study of 261 very low birth weight (VLBW) infants admitted at a tertiary academic center. Based on the site of inflammation, HC was categorized: any HC; amnionitis; funisitis; amnionitis+funisitis. The extent of inflammation in each site was reflected by sub-defining high grade (HG). The incidences of morbidities in infants with and without HC were compared. The bronchopulmonary dysplasia (BPD) rate was significantly higher in infants with amnionitis and the severe retinopathy of prematurity (ROP) rate was significantly higher in infants with any HC and funisitis. After adjustment for both gestational age and birth weight, the respiratory distress syndrome (RDS) rate was significantly lower in infants with all categories of HC except for HG amnionitis and HG funisitis, which are not associated with lower RDS rate. HG amnionitis was significantly associated with increased BPD rate but the association of HC with severe ROP disappeared. In conclusion, HC is significantly associated with decreased RDS and HG amnionitis with increased BPD while lacking association with other neonatal morbidities in VLBW infants. The association with HC and neonatal morbidities differs by the site and extent of chorioamnionitis.
