Minimal invasive coronary surgery is not associated with increased mortality or morbidity during the period of learning curve.

BACKGROUND: Minimally invasive procedures for coronary revascularization have been performed for over 20 years; however, their technical complexity, steep learning curves and absence of training programs explain the weak acceptance of these techniques. The aim of this study is to describe the step-by-step learning process on how to establish a minimally invasive coronary artery revascularization program. The short-term outcomes of our first 30 patients were compared to our left internal mammary artery (LIMA) to left anterior descending (LAD) artery off pump coronary artery bypass (OPCAB) cohort as a quality control baseline. METHODS: All patients who benefited from an endoscopic atraumatic coronary artery bypass (Endo-ACAB) in our hospital, from July 2018 to May 2020 (n = 30) were identified. Baseline demographics, peri, postoperative and laboratory data were extracted from each patient's medical records. These results were compared to our LIMA-LAD OPCAB cohort (n = 23). RESULTS: Twenty-eight patients were planned for a single LIMA-LAD Endo-ACAB. The remaining two had a T-graft double Endo-ACAB. Ten patients had a hybrid revascularization with the culprit lesion being treated first. Three patients were converted to sternotomy because of a LIMA lesion during thoracoscopic harvesting. We accounted three major adverse cardiovascular events (MACE). Demographic, peri and postoperative data showed no significant differences between the Endo-ACAB and the OPCAB group. CONCLUSION: Endo-ACAB is a technically demanding operation, however, it can safely be introduced in centers with no previous experience with no extra cost in terms of morbidity or mortality. Thoracoscopic LIMA harvesting is the most demanding surgical skill to acquire.

An asymptomatic Lima dissection after a programmed hybrid revascularization procedure turned to nightmare.

A 71-year-old female with symptomatic bitroncular coronary ischemic disease was admitted in our hospital for hybrid revascularization. She presented significant stenosis of the proximal and middle left anterior descending artery (LAD) and of the second segment of right coronary artery (RCA). She was scheduled for an Endoscopic Atraumatic Coronary Artery Bypass (EACAB) of the left internal mammary artery (LIMA) to LAD and staged percutaneous coronary intervention (PCI) to RCA after the EACAB. Control of LIMA permeability after RCA PCI showed LIMA dissection with TIMI 2 flow to LAD. Decision to stent a freshly implanted LIMA led to LIMA rupture. An emergent LAD revascularization with a saphenous vein graft and control of bleeding was successfully performed. Patient was discharged at day 10 from the hospital.

Impact of neoadjuvant chemoradiotherapy on postoperative outcomes after esophageal cancer resection: results of a European multicenter study.

OBJECTIVES: To assess the impact of neoadjuvant chemoradiotherapy (NCRT) on anastomotic leakage (AL) and other postoperative outcomes after esophageal cancer (EC) resection. BACKGROUND: Conflicting data have emerged from randomized studies regarding the impact of NCRT on AL. METHODS: Among 2944 consecutive patients operated on for EC between 2000 and 2010 in 30 European centers, patients treated by NCRT after surgery (n=593) were compared with those treated by primary surgery (n=1487). Multivariable analyses and propensity score matching were used to compensate for the differences in some baseline characteristics. RESULTS: Patients in the NCRT group were younger, with a higher prevalence of male sex, malnutrition, advanced tumor stage, squamous cell carcinoma, and surgery after 2005 when compared with the primary surgery group. Postoperative AL rates were 8.8% versus 10.6% (P=0.220), and 90-day postoperative mortality and morbidity rates were 9.3% versus 7.2% (P=0.110) and 33.4% versus 32.1% (P=0.564), respectively. Pulmonary complication rates did not differ between groups (24.6% vs 22.5%; P=0.291), whereas chylothorax (2.5% vs 1.2%; P=0.020), cardiovascular complications (8.6% vs 0.1%; P=0.037), and thromboembolic events (8.6% vs 6.0%; P=0.037) were higher in the NCRT group. After propensity score matching, AL rates were 8.8% versus 11.3% (P=0.228), with more chylothorax (2.5% vs 0.7%; P=0.030) and trend toward more cardiovascular and thromboembolic events in the NCRT group (P=0.069). Predictors of AL were high American Society of Anesthesiologists scores, supracarinal tumoral location, and cervical anastomosis, but not NCRT. CONCLUSIONS: Neoadjuvant chemoradiotherapy does not have an impact on the AL rate after EC resection (NCT 01927016).

Infectious Mononucleosis Resulting in Acute Necrotizing Mediastinitis: A Case Report and Literature Review.

The serological prevalence of Epstein-Barr virus (EBV) among young adults exceeds 90% worldwide. Even though EBV primary infection is usually benign, severe complications can occur in adolescents and young adults and so the disease must be promptly diagnosed. The development of an oropharyngeal abscess leading to a descending necrotizing mediastinitis (DNM) is exceptional and potentially lethal, so early diagnosis with a CT scan, appropriate antibiotics and surgery are essential. The authors present a case where DNM was associated with reactive hemophagocytic syndrome as a result of infectious mononucleosis, as well as a review of similar cases in the English literature. LEARNING POINTS: The incidence of serious complications in Epstein-Barr virus (EBV) primary infection increases with age.Respiratory symptoms (e.g., pleuritic pain, dyspnoea) and unusually prolonged fever (>10 days) in patients with infectious mononucleosis could be 'red flags' for life-threatening complications such as empyema and descending necrotizing mediastinitis.The threshold for performing cervical and chest computed tomography in septic patients with infectious mononucleosis should be low.

A successful transdiaphragmatic shunting for a late and recurrent pericardial effusion following coronary bypass.

Although pericardial effusion (PE) is common after cardiac surgery, late and recurrent cardiac tamponade that occurs more than 5-7 days after coronary artery bypass grafting is an infrequent complication. Moreover, the treatment of PE resistant to medical therapy, percutaneous drainage and pleuro-pericardial window remains a therapeutic challenge. We report the case of a recalcitrant PE with high-daily volume outflow drainage, finally treated with success, with a transdiaphragmatic pleuro-peritoneal shunting by laparoscopic approach.

Totally endoscopic lobectomy and segmentectomy for congenital bronchial atresia.

Congenital bronchial atresia is a congenital obliteration of a segmental or lobar bronchus resulting in an inflation of the correspondent parenchyma. It may lead to infectious complications and in the long-term to alteration of the adjacent lung parenchyma. As it usually occurs in young and healthy patients with normal lungs, this disorder is particularly suitable for a full endoscopic pulmonary resection. We report our recent experience of two lobectomies and one segmentectomy in three patients.
