Long-Term Follow-Up of Abdominal Wall Reconstruction after Planned Ventral Hernia: A 15-Year Experience

BACKGROUND Although damage control strategies and the open abdomen have improved survival, they present their own unique set of challenges in caring for the multiply injured trauma patient. We previously reported the technique of staged abdominal wall closure for the management of the open abdomen. The purpose of this study was to evaluate the efficacy of various techniques of abdominal wall reconstruction (final stage of management) on long-term outcomes after planned ventral hernia, and to better define risk factors for recurrence. STUDY DESIGN Patients undergoing abdominal wall reconstruction over a 15-year period were identified and stratified by gender, age, severity of shock, injury severity, and method of repair: secondary fascial closure +/- prosthetic, standard components separation (SCS) +/- prosthetic and modified components separation (MCS) +/- prosthetic. Long-term outcomes (recurrence) were determined using hospital records, telephone interview, and physical examination. Multivariable logistic regression analysis was performed to determine independent predictors of recurrence. RESULTS One hundred fifty-two patients were identified. Fourteen (9%) patients underwent secondary fascial closure +/- prosthetic, 47 (31%) underwent SCS +/- prosthetic, and 91 (60%) underwent MCS +/- prosthetic. Long-term follow-up (up to 14.6 years, mean 5.3 years) was obtained in 114 (75%) patients. Sixteen patients (14%) had a recurrence. Prosthetic use increased recurrence 4-fold. There were 2 known recurrences (5%) in patients with MCS without prosthetic. Logistic regression identified both female gender and body mass index as independent predictors of recurrence. CONCLUSIONS The MCS technique is the procedure of choice for repair of giant abdominal wall defects. This approach can avoid the need for prosthetics. In fact, MCS without prosthetic resulted in an acceptably low hernia recurrence rate (5%).

Right thoracotomy for mitral reoperation: analysis of technique and outcome

BACKGROUND This report describes technical details of the right thoracotomy approach for mitral surgery, and analyzes our experience with this procedure for patients with a prior sternotomy. Three methods for myocardial management (hypothermic cardioplegic arrest, beating heart, and fibrillating heart) are compared. METHODS Records were abstracted of patients who had a right thoracotomy between January 1, 1992 and July 1, 1999 for mitral surgery after at least one prior sternotomy. Demographic, operative, and outcome data were collected for analysis. Telephone follow-up was used to measure postoperative New York Heart Association functional status. RESULTS Eighty-four patients (mean age 60 +/- 15 years) had reoperative mitral surgery via a right thoracotomy. Myocardial management included ventricular fibrillation in 10 patients, operation on the beating heart in 58 patients, and hypothermic blood cardioplegia arrest in 16 patients. The mean time in the operating room was 185 +/- 73 minutes, and the mean duration of cardiopulmonary bypass was 63 +/- 56 minutes. There were no perioperative strokes and the prevalence of death for patients who received cardioplegic arrest was significantly higher than the prevalence of death for patients who had mitral surgery with perfused fibrillating or beating heart techniques (p = 0.007; Fishers exact test comparing risk-unadjusted mortality). CONCLUSIONS Right thoracotomy provides efficient exposure for reoperative mitral surgery. Mitral valve procedures on the fibrillating or beating heart are feasible in most patients and are at least as safe as surgery using cardioplegic arrest.

Complete repair of Ebstein anomaly in neonates and young infants: A 16-year follow-up

OBJECTIVE The purpose of this study was to review the long-term outcome of patients with Ebstein anomaly who underwent complete repair as neonates and young infants. METHODS Between March 1994 and May 2010, 32 patients (23 neonates and 9 young infants) underwent surgery for Ebstein anomaly. Mean weight was 3.9 ± 2.0 kg (range, 1.9-8.6 kg). The Great Ormond Street Echocardiography score was greater than 1.5 in 22 of the 23 neonates and greater than 1.0 in all infants. All associated cardiac defects were repaired including pulmonary atresia in 15 and ventricular septal defect in 4. Primary outcome measures included (1) early and late survival, (2) freedom from reoperation, (3) durability of tricuspid valve repair, and (4) functional status. RESULTS Early survival was 78.1% (25/32). There was 1 late death. Fifteen-year survival estimate was 74% ± 8%. For patients with pulmonary atresia, early and late survival was 60% ± 12% (9/15) versus 94.1% (16/17) (P < .05), respectively; for those without pulmonary atresia, early and late survival was 60% ± 12% versus 85% ± 10 (P = .06), respectively. The mean follow-up was 5.9 ± 4.5 years (0.1-16 years). A biventricular repair was achieved in 90.6% (29/32) patients. Median preoperative tricuspid regurgitation was 4/4 and at late follow-up, 1/4. Freedom from reoperation at 15 years was 74% ± 10% for patients undergoing biventricular repair. All survivors are in New York Heart Association class I or II. CONCLUSIONS Biventricular repair of Ebstein anomaly in symptomatic neonates is feasible with good early and late survival, especially in those without pulmonary atresia. Tricuspid valve repair is durable, and functional status is excellent.

Intestinal Malrotation Discovered at the Time of Laparoscopic Roux-en-Y Gastric Bypass

Four morbidly obese women who met the NIH criteria for bariatric surgery had laparoscopic Roux-en-Y gastric bypass. At operation, each was found to have intestinal malrotation. Two cases were completed laparoscopically, and two were converted to open operation because of difficulty defining the anatomy. All four operations were successful with no immediate complications and patients tolerated the procedures well. We present the four cases and offer recommendations should this unusual congenital defect be discovered at the time of laparoscopic gastric bypass.

Surgical Decision Making in Neonatal Ebstein's Anomaly: An Algorithmic Approach Based on 48 Consecutive Neonates.

Objective: There is currently no consensus of opinion regarding the optimal surgical management of Ebstein’s anomaly (EA) in neonates and young infants. Reported early mortality rates range from 25% to 100%. In this study, we present an algorithm for choosing the best management option for neonates with EA based on analysis of our experience. Patients and Methods: From 1994 to June, 2011, 48 neonates with a diagnosis of EA were managed by the same surgical team. Of these, two died before intervention; the remaining 46 either were managed medically initially (n = 20) or underwent surgical intervention during the neonatal period (n = 26) or early infancy (n = 9). Results: The mean weight was 3.6 ± 1.7 kg (1.9-8.6) and mean follow-up time was 6.3 ± 4.5 years (0.2-16). Of the 20 patients initially managed medically, 11 remain well without intervention and nine required complete repair in infancy, with 100% survival. Of the 26 neonatal operations, 23 (88%) were complete biventricular repairs, 1 Starnes’ palliation, and two Blalock–Taussig shunts (BTSs) ± pulmonary valvotomy. Among those having a two-ventricle repair, anatomic pulmonary atresia (APA) was a risk factor for early mortality (46.1%, 6 of 13) compared with those without pulmonary atresia (EA/no-PA; 10%, 1 of 10), P < .05. Conclusions: Most symptomatic neonates with EA will require early operation. For those with APA and mild tricuspid regurgitation (TR), a modified BTS and reduction atrioplasty may be the best initial option. For those with functional pulmonary atresia and severe TR and pulmonary regurgitation, ligation of the main pulmonary artery and placement of a BTS may provide the best initial palliation. For the rest, either a biventricular repair or a single-ventricle palliation is indicated.

Fungal infections in ventricular assist devices.

Device infections in patients supported by a mechanical circulatory support system remain an important problem, particularly as we enter the era of permanent device implantation. This article focuses on fungal infections that occur in patients with ventricular assist devices. The nature of fungal, especially Candida species, colonization and infection in severely ill, hospitalized patients will be described. Information regarding the effect of the artificial surface-blood interface on the immune systems ability to combat fungal organisms will also be presented. Basic aspects of the fungal-host interaction serve as the foundation for a discussion of clinical management protocols for preventing and treating fungal infections in patients supported by a ventricular assist device.

Surgical management of intrapericardial teratoma in the fetus.

Intrapericardial teratomas often present as life-threatening problems when diagnosed during fetal life. They are large lesions that compress the heart and lungs and can result in tamponade if not treated expeditiously. We present a case of a large teratoma that was managed by prenatal pericardiocentesis followed by surgical resection.

Components separation for abdominal wall reconstruction: The Memphis modification

Since the advent of damage control surgery, more patients are left with an open abdomen. Surgeons are then left with the challenge of how to restore continuity of the abdominal wall. Many different techniques have been utilized for reconstruction with widely variable recurrence rates, mainly depending on the length of follow-up. A modification of the components separation technique was developed in Memphis, Tennessee at the Presley Memorial Trauma Center. This modification greatly increased the length gained in the midline. Additionally, many patients can be reconstructed without the use of prosthetics, reducing the infectious complications. The purpose of this manuscript is to describe in detail how to perform a modification of the components separation technique that has been shown to have one of the lowest recurrence rates in the literature.

Current Trends in the Management of Neonates With Ebstein's Anomaly.

Background: The optimal management strategy for neonates with Ebsteins anomaly is unknown. This analysis was undertaken to assess current trends in the management and prognosis of neonates born with Ebsteins anomaly in the United States, as reflected in an administrative database. Methods: The Pediatric Health Information System database (40 children’s hospitals) was used to review the reported incidence and available data on neonates with Ebsteins anomaly treated in the United States between 2003 and 2007. Primary outcome was hospital survival. Of the 415 patients identified, 257 (62%) did not undergo initial surgical intervention as neonates. Aortopulmonary shunt only was done on 63 patients (15%), single-ventricle palliation on 36 (9%), two-ventricle repair on 16 (4%), heart transplantation in 3 (1%), and a catheter-based intervention or a hybrid palliative approach was applied in 40 (10%). Intergroup comparisons were done using chi-square analyses. Results: Mortality for the entire cohort was 24% (100 of 415). For medically treated patients, this was 22% (56 of 257). For surgically treated and hybrid patients, this was 30% and 23%, respectively (P = NS). Conclusions: The majority of patients born with Ebsteins anomaly currently do not undergo surgical intervention as neonates. Significant early mortality in this group suggests that certain subsets of patients may benefit from earlier surgical intervention. Among the severely symptomatic neonates who do undergo early surgical intervention, the mortality remains high, irrespective of the surgical approach taken. A multicenter trial may be appropriate to identify strategies to optimize care for these critically ill neonates. Further analysis of risk factors for early mortality is warranted.

Supravalvar aortic stenosis in infancy.

Supravalvar aortic stenosis (SVAS) is a rare anomaly of the aortic root caused by a genetically based deficiency in elastin production. Concomitant primary and secondary cardiovascular lesions complicate surgical management and impact early and late outcomes. Because SVAS is a rare lesion, surgical series are relatively small and span lengthy time periods. Consequently, risk factors that influence early and late outcomes are not well defined. Patients who come to surgery during infancy are particularly challenging, but little attention has been directed as to whether or not young age influences outcomes. This review suggests that complicating associated features of elastin arteriopathy are more prevalent in patients who require relief of SVAS during infancy, and that concomitant lesions significantly increase the difficulty and risk of treating younger patients with SVAS.
