Inter-Facility Transport on Extracorporeal Life Support: Clinical Outcomes and Comparative Analysis with In-house Patients

BACKGROUND: Extracorporeal life support (ECLS) is widely used in refractory heart or lung failure, and the demand for inter-facility transportation on ECLS is expanding. However, little is known about post-transportation outcomes, the clinical safety of such transportation, or the characteristics of the transported patients. METHODS: This was a retrospective review of a 3-year, single-institution experience with inter-facility ECLS transport, as well as a comparative analysis of clinical outcomes with those of in-house patients. We also analyzed the risk factors for hospital mortality in the entire ECLS population using univariate and multivariate analyses to investigate the effects of transport. RESULTS: All 44 patients were safely transported without adverse events. The average travel distance was 178.7 km, with an average travel time of 74.0 minutes. Early survival of the transported group seemed to be better than that of the in-house group, but the difference was not statistically significant (70.5% vs. 56.6%, p=0.096). The incidence of complications was similar between the 2 groups, except for critical limb ischemia, which was significantly more common in the transported group than in the in-house group (25.0% vs. 8.1%, p=0.017). After adjusting for confounders, being part of the transported group was not a predictor of early death (adjusted odds ratio, 0.689; p=0.397). CONCLUSION: Transportation of patients on ECLS is relatively safe, and the clinical outcomes of transported patients are comparable to those of in-house ECLS patients. Although matched studies are required, our study demonstrates that transporting patients on ECLS did not increase their risk of hospital mortality after adjustment for other factors.

Surgical Treatment of Anastomotic Recurrence after Gastrectomy for Gastric Cancer

BACKGROUND: The purpose of this study was to evaluate the outcome of reoperation with curative intent for the treatment of anastomotic recurrent gastric cancer. METHODS: Ten patients with anastomotic recurrence of gastric cancer who underwent reoperation from November 1995 to February 2011 were analyzed retrospectively. The time interval between the first operation and reoperation, recurrence pattern, type of surgery, survival, and postoperative outcome were analyzed. RESULTS: The average time to recurrence after initial surgery was 48.8 months (median, 23.5 months). Of the ten patients, eight (80.0%) had recurrence at the esophagojejunostomy, one (10.0%) at the esophagogastrostomy, and two (20.0%) at the esophagus. Among these patients, five had combined metastasis or invasion to major organs in addition to anastomotic recurrence. Complete resection was achieved in five patients (50.0%), and incomplete resection or bypass surgery was performed in the remaining five patients (50.0%). The overall median survival time was 7.0 months (range, 2.2 to 105.5 months). The median survival time following complete resection and palliative surgery (incomplete resection or bypass surgery) was 28.1 months (range, 4.2 to 105.5 months) and 5.5 months (range, 2.2 to 7.5 months), respectively. CONCLUSION: Surgical resection of anastomotic recurrent gastric cancer should be implemented only in selected patients in whom complete resection is possible.

Technique of Coronary Transfer for TGA with Single Coronary Artery

An eight-day-old neonate was diagnosed with dextro-transposition of the great arteries, atrial septal defect, patent ductus arteriosus, and a single sinus origin of the coronary arteries. The single coronary artery originated from the left sinus (sinus 2), had a proximal left circumflex arterial branch, and passed anteriorly to the right side of the aorta, further branching into the right coronary and left anterior descending arteries. We successfully performed an arterial switch operation and coronary transfer by tube graft reconstruction with autologous aortic tissue to treat the dextro-transposition of the great arteries and atrial septal defect with a single-sinus origin of the coronary arteries.

Cardiac Resynchronization Therapy Using a Dual Chamber Pacemaker in Patients with Severe Left Ventricular Dysfunction and a Left Bundle Branch Block

Through the use of a dual chamber (DDD) pacemaker, we achieved a cardiac resynchronization effect in a 51-year-old female patient who was transferred to our hospital from another hospital for an operation for three-vessel coronary artery disease. Her electrocardiogram showed a left bundle branch block (LBBB) and a prolonged QRS interval of 166 milliseconds. Severe left ventricle (LV) dysfunction was diagnosed via echocardiography. Coronary artery bypass grafting (CABG) was then performed. In order to accelerate left atrial activation and reduce the conduction defect, DDD pacing using right atrial and left and right ventricular pacing wires was initiated postoperatively. The cardiac output was measured immediately, and one and twelve hours after arrival in the intensive care unit. The cardiac output changed from 2.8, 2.4, and 3.6 L/min without pacing to 3.5, 3.4, and 3.5 L/min on initiation of pacing. The biventricular synchronization using DDD pacing was turned off 18 hours after surgery. She was transferred to a general ward with a cardiac output of 3.9 L/min. In patients with coronary artery disease, severe LV dysfunction, and LBBB, cardiac resynchronization therapy can be achieved through DDD pacing after CABG.

Bridge to Transplantation with a Left Ventricular Assist Device

A 61-year-old female patient was diagnosed with dilated cardiomyopathy with severe left ventricle dysfunction. Two days after admission, continuous renal replacement therapy was performed due to oliguria and lactic acidosis. On the fifth day, an intra-aortic balloon pump was inserted due to low cardiac output syndrome. Beginning 4 days after admission, she was supported for 15 days thereafter with an extracorporeal left ventricular assist device (LVAD) because of heart failure with multi-organ failure. A heart transplant was performed while the patient was stabilized with the LVAD. She developed several complications after the surgery, such as cytomegalovirus pneumonia, pulmonary tuberculosis, wound dehiscence, and H1N1 infection. On postoperative day 19, she was discharged from the hospital with close follow-up and treatment for infection. She received follow-up care for 10 months without any immune rejection reaction.
