Prognosis of Reflux Symptom Resolution After Bariatric Surgery: How Can Preoperative Esophageal Testing Help?

PURPOSE: The incidence of unresolved postoperative reflux after bariatric surgery varies considerably. Consistent perioperative patient characteristics predictive of unresolved reflux remain unknown. We leverage our institution's comprehensive preoperative esophageal testing to identify predictors of postoperative reflux. MATERIALS AND METHODS: We performed a single-center retrospective review of adult patients with preoperative reflux symptoms who underwent either vertical sleeve gastrectomy (VSG) or Roux-en-Y gastric bypass (RYGB) from 2015 to 2021. All patients had pH and high-resolution manometry preoperatively. Predictors of postoperative unresolved reflux at 1 year were explored via Fisher's exact test, Kruskal Wallis test, and univariate logistic regression. RESULTS: Unresolved reflux was higher in patients undergoing VSG (n = 60/129,46.5%) vs. RYGB (n = 19/98, 19.4%). Median DeMeester scores were higher (22 vs. 13, p = .07) along with rates of ineffective esophageal motility (IEM) (31.6 vs. 8.9%, p = .01) in the 19 (19.3%) patients with unresolved postoperative reflux after RYGB compared to the resolved RYGB reflux cohort. Sixty (46.5%) of VSG patients had unresolved postoperative reflux. The VSG unresolved reflux cohort had similar median DeMeester and IEM incidence to the resolved VSG group but more preoperative dysphagia (13.3% vs. 2.9%, p = .04) and higher preoperative PPI use (56.7 vs. 39.1%, p = .05). In univariate analysis, only IEM was predictive of unresolved reflux after RYGB (OR 4.74, 95% CI 1.37, 16.4). CONCLUSION: Unresolved reflux was higher after VSG. Preoperative IEM predicted unresolved reflux symptoms after RYGB. In VSG patients, preoperative dysphagia symptoms and PPI use predicted unresolved reflux though lack of correlation to objective testing highlights the subjective nature of symptoms and the challenges in predicting postoperative symptomatology.

Laparoscopic Heller myotomy with Toupet fundoplication: revisiting GERD in treated achalasia.

INTRODUCTION: With the advent of the laparoscopic era in the 1990s, laparoscopic Heller myotomy replaced pneumatic dilation as the first-line treatment for achalasia. An advantage of this approach was the addition of a fundoplication to reduce gastroesophageal reflux disease (GERD). More recently, Peroral Endoscopic Myotomy has competed for first-line therapy, but the postoperative GERD may be a weakness. This study leverages our experience to characterize GERD following LHM with Toupet fundoplication (LHM+T ) so that other treatments can be appropriately compared. METHODS: A single-institution retrospective review of adult patients with achalasia who underwent LHM+T from January 2012 to April 2022 was performed. We obtained routine 6-month postoperative pH studies and patient symptom questionnaires. Differences in questionnaires and reflux symptoms in relation to pH study were explored via Kruskal-Wallis test or chi-square tests. RESULTS: Of 170 patients who underwent LHM+T , 51 (30%) had postoperative pH testing and clinical symptoms evaluation. Eleven (22%) had an abnormal pH study; however, upon manual review, 5 of these (45.5%) demonstrated low-frequency, long-duration reflux events, suggesting poor esophageal clearance of gastric refluxate and 6/11 (54.5%) had typical reflux episodes. Of the cohort, 7 (15.6%) patients reported GERD symptoms. The median [IQR] severity was 1/10 [0, 3] and median [IQR] frequency was 0.5/4 [0, 1]. Patients with abnormal pH reported more GERD symptoms than patients with a normal pH study (3/6, 50% vs 5/39, 12.8%, p = 0.033). Those with a poor esophageal clearance pattern (n = 5) reported no concurrent GERD symptoms. CONCLUSION: The incidence of GERD burden after LHM+T is relatively low; however, the nuances relevant to accurate diagnosis in treated achalasia patients must be considered. Symptom correlation to abnormal pH study is unreliable making objective postoperative testing important. Furthermore, manual review of abnormal pH studies is necessary to distinguish GERD from poor esophageal clearance.

Esophageal Motility Patterns in Paraesophageal Hernia Patients Compared to Sliding Hiatal Hernia: Bigger Is Not Better.

BACKGROUND: In patients with paraesophageal hernias (PEH), the course of the esophagus is often altered, which may affect esophageal motility. High-resolution manometry (HRM) is frequently used to evaluate esophageal motor function prior to PEH repair. This study was performed to characterize esophageal motility disorders in patients with PEH as compared to sliding hiatal hernia and to determine how these findings affect operative decision-making. METHODS: Patients referred for HRM to a single institution from 2015 to 2019 were included in a prospectively maintained database. HRM studies were analyzed for the appearance of any esophageal motility disorder using the Chicago classification. PEH patients had confirmation of their diagnosis at the time of surgery, and the type of fundoplication performed was recorded. They were case-matched based on sex, age, and BMI to patients with sliding hiatal hernia who were referred for HRM in the same period. RESULTS: There were 306 patients diagnosed with a PEH who underwent repair. When compared to case-matched sliding hiatal hernia patients, PEH patients had higher rates of ineffective esophageal motility (IEM) (p<.001) and lower rates of absent peristalsis (p=.048). Of those with ineffective motility (n=70), 41 (59%) had a partial or no fundoplication performed during PEH repair. CONCLUSION: PEH patients had higher rates of IEM compared to controls, possibly due to a chronically distorted esophageal lumen. Offering the appropriate operation hinges on understanding the involved anatomy and esophageal function of each individual. HRM is important to obtain preoperatively for optimizing patient and procedure selection in PEH repair.

Preoperative esophageal testing predicts postoperative reflux status in sleeve gastrectomy patients.

BACKGROUND: Patients who undergo vertical sleeve gastrectomy (VSG) are at risk of postoperative GERD. The reasons are multifactorial, but half of conversions to Roux-en Y gastric bypass are for intractable GERD. Our institution routinely performs preoperative pH and high-resolution manometry studies to aid in operative decision making. We hypothesize that abnormal pH studies in concert with ineffective esophageal motility would lead to higher rates of postoperative reflux after VSG. METHODS: A single institution retrospective review was conducted of adult patients who underwent preoperative pH and manometry testing and VSG between 2015 and 2021. Patients filled out a symptom questionnaire at the time of testing. Postoperative reflux was defined by patient-reported symptoms at 1-year follow-up. Univariate logistic regression was used to examine the relationship between esophageal tests and postoperative reflux. The Lui method was used to determine the cutpoint for pH and manometric variables maximizing sensitivity and specificity for postoperative reflux. RESULTS: Of 291 patients who underwent VSG, 66 (22.7%) had a named motility disorder and 67 (23%) had an abnormal DeMeester score. Preoperatively, reflux was reported by 122 patients (41.9%), of those, 69 (56.6%) had resolution. Preoperative pH and manometric abnormalities, and BMI reduction did not predict postoperative reflux status (p = ns). In a subgroup analysis of patients with an abnormal preoperative pH study, the Lui cutpoint to predict postoperative reflux was a DeMeester greater than 24.8. Postoperative reflux symptoms rates above and below this point were 41.9% versus 17.1%, respectively (p = 0.03). CONCLUSION: While manometry abnormalities did not predict postoperative reflux symptoms, GERD burden did. Patients with a mildly elevated DeMeester score had a low risk of postoperative reflux compared to patients with a more abnormal DeMeester score. A preoperative pH study may help guide operative decision-making and lead to better counseling of patients of their risk for reflux after VSG.

Type II hiatal hernias: do they exist or are they actually parahiatal hernias?

BACKGROUND: Type II hiatal hernias (HH) are characterized by a portion of the gastric fundus located above the esophageal hiatus adjacent to the esophagus while the gastroesophageal junction (GEJ) remains fixed below the esophageal hiatus. This type of HH has been called the "true" paraesophageal hernia (PEH) because the fundus appears to the side of the esophagus. In our experience, Type II HHs are occasionally identified on radiographic testing, however they are rarely, if ever, confirmed intraoperatively. This led to our question: Does Type II HH exist? METHODS: We searched for evidence of type II HH in three locations: 1. Retrospective review of all first-time PEH repairs (excluding Type I HHs and re-operative cases) performed at the University of Washington Medical Center from 1994 to 2021; 2. Operative videos available on YouTube and WebSurg websites; and 3. Abstracts from the SAGES annual meetings from 2005 to 2021. RESULTS: We found no evidence of Type II HH in any of our three searches. We performed 846 PEH repairs: 760 Type III, 75 Type IV, and 11 parahiatal. Upon website video review, we found only one possible type II hernia, though it too was likely a para-hiatal hernia. No video or case presentations of a type II HH were identified within SAGES annual meeting abstracts. CONCLUSION: Type II HHs do not exist as they are currently defined. Although uncommon, parahiatal hernia can easily be misinterpreted as Type II HH. We should consider changing the hiatal hernia classification system to prevent ongoing clinical confusion.

Cancer control funding in Nigeria: A case for universal health coverage.

Nigeria's health spending per capita remains relatively low, with an out-of-pocket expenditure on health estimated at three-quarters of the nation's health expenditure in 2018. A large percentage of the population cannot afford-and have limited access to-cancer treatment services. Our study was aimed at analyzing all cancer funding-related policies from 2010 to 2020. We used qualitative methods to contextualize the challenges of funding cancer control, and recommend steps in policy implementation needed to achieve universal health coverage (UHC) for cancer care in Nigeria. We found that cancer control is grossly underfunded, with a glaring lack of political will identified by most participants as the root cause of underfunding. Recommendations by the participants included mandatory enrollment in health insurance schemes, encouraging public-private partnerships and advocacy for increased taxation to democratize access to treatment. Additionally, channeling a portion of tax revenues from tobacco sales to cancer will reduce catastrophic health spending and move Nigeria closer toward achieving UHC for cancer.

Characteristics and outcomes of patients undergoing paraesophageal hernia repair with selective use of biologic mesh.

BACKGROUND: The use of biologic mesh in paraesophageal hernia repair (PEHR) has been associated with decreased short-term recurrence but no statistically significant difference in long-term recurrence. Because of this, we transitioned from routine to selective use of mesh for PEHR. The aim of this study was to examine our indications for selective mesh use and to evaluate patient outcomes in this population. METHODS: We queried a prospectively maintained database for patients who underwent laparoscopic PEHR with biologic mesh from October 2015 to October 2018, then performed a retrospective chart review. The decision to use mesh was made intraoperatively by the surgeon. Recurrence was defined as the presence of > 2 cm intrathoracic stomach on postoperative upper gastrointestinal (UGI) series. RESULTS: Mesh was used in 61/169 (36%) of first-time PEHRs, and in 47/82 (57%) of redo PEHRs. Among first-time PEHRs, the indications for mesh included hiatal tension (85%), poor crural tissue quality (11%), or both (5%). Radiographic recurrence occurred in 15% of first-time patients (symptomatic N = 2, asymptomatic N = 3). There were no reoperations for recurrence. Among redo PEHRs, the indication for mesh was most commonly the redo nature of the repair itself (55%), but also hiatal tension (51%), poor crural tissue quality (13%), or both (4%). Radiographic recurrence occurred in 21% of patients (symptomatic N = 4, asymptomatic N = 1). There was 1 reoperation for recurrence in the redo-repair group. CONCLUSIONS: We selectively use biologic mesh in a third of our first-time repair patients and in over half of our redo-repair patients when there is a perceived high risk of recurrence based on hiatal tension, poor tissue quality, or prior recurrence. Despite the high risk for radiologic recurrence, there was only 1 reoperation for recurrence in the entire cohort.

Characterization of tracheobronchomalacia in infants with hypophosphatasia.

BACKGROUND: Perinatal and infantile hypophosphatasia (HPP) are associated with respiratory failure and respiratory complications. Effective management of such complications is of key clinical importance. In some infants with HPP, severe tracheobronchomalacia (TBM) contributes to respiratory difficulties. The objective of this study is to characterize the clinical features, investigations and management in these patients. METHODS: We report a case series of five infants with perinatal HPP, with confirmed TBM, who were treated with asfotase alfa and observed for 3-7 years. Additionally, we reviewed respiratory function data in a subgroup of patients with perinatal and infantile HPP included in the clinical trials of asfotase alfa, who required high-pressure respiratory support (positive end-expiratory pressure [PEEP] ≥6 cm H2O and/or peak inspiratory pressure ≥18 cm H2O) during the studies. RESULTS: The case series showed that TBM contributed significantly to respiratory morbidity, and prolonged respiratory support with high PEEP was required. However, TBM improved over time, allowing weaning of all patients from ventilator use. The review of clinical trial data included 20 patients and found a high degree of heterogeneity in PEEP requirements across the cohort; median PEEP was 8 cm H2O at any time and some patients presented with high PEEP (≥8 cm H2O) over periods of more than 6 months. CONCLUSION: In infants with HPP presenting with persistent respiratory complications, it is important to screen for TBM and initiate appropriate respiratory support and treatment with asfotase alfa at an early stage.

Laparoscopic anti-reflux surgery for the treatment of idiopathic pulmonary fibrosis (WRAP-IPF): a multicentre, randomised, controlled phase 2 trial.

BACKGROUND: Abnormal acid gastro-oesophageal reflux (GER) is hypothesised to play a role in progression of idiopathic pulmonary fibrosis (IPF). We aimed to determine whether treatment of abnormal acid GER with laparoscopic anti-reflux surgery reduces the rate of disease progression. METHODS: The WRAP-IPF trial was a randomised controlled trial of laparoscopic anti-reflux surgery in patients with IPF and abnormal acid GER recruited from six academic centres in the USA. We enrolled patients with IPF, abnormal acid GER (DeMeester score of ≥14·7; measured by 24-h pH monitoring) and preserved forced vital capacity (FVC). We excluded patients with a FVC below 50% predicted, a FEV1/FVC ratio of less than 0·65, a history of acute respiratory illness in the past 12 weeks, a body-mass index greater than 35, and known severe pulmonary hypertension. Concomitant therapy with nintedanib and pirfenidone was allowed. The primary endpoint was change in FVC from randomisation to week 48, in the intention-to-treat population with mixed-effects models for repeated measures. This trial is registered with ClinicalTrials.gov, number NCT01982968. FINDINGS: Between June 1, 2014, and Sept 30, 2016, we screened 72 patients and randomly assigned 58 patients to receive surgery (n=29) or no surgery (n=29). 27 patients in the surgery group and 20 patients in the no surgery group had an FVC measurement at 48 weeks (p=0·041). Intention-to-treat analysis adjusted for baseline anti-fibrotic use demonstrated the adjusted rate of change in FVC over 48 weeks was -0·05 L (95% CI -0·15 to 0·05) in the surgery group and -0·13 L (-0·23 to -0·02) in the non-surgery group (p=0·28). Acute exacerbation, respiratory-related hospitalisation, and death was less common in the surgery group without statistical significance. Dysphagia (eight [29%] of 28) and abdominal distention (four [14%] of 28) were the most common adverse events after surgery. There was one death in the surgery group and four deaths in the non-surgery group. INTERPRETATION: Laparoscopic anti-reflux surgery in patients with IPF and abnormal acid GER is safe and well tolerated. A larger, well powered, randomised controlled study of anti-reflux surgery is needed in this population. FUNDING: US National Institutes of Health National Heart, Lung and Blood Institute.

Primary versus Staged Closure of Exomphalos Major: Cardiac Anomalies Do Not Affect Outcome.

AIM: The objective of the study is to describe management of exomphalos major and investigate the effect of congenital cardiac anomalies. METHODS: A single-center retrospective review (with audit approval) was performed of neonates with exomphalos major (fascial defect ≥ 5cm ± liver herniation) between 2004 and 2014.Demographic and operative data were collected and outcomes compared between infants who had primary or staged closure. Data, median (range), were analyzed appropriately. RESULTS: A total of 22 patients were included, 20 with liver herniation and 1 with pentalogy of Cantrell. Gestational age was 38 (30-40) weeks, birth weight 2.7 (1.4-4.6) kg, and 13 (60%) were male. Two were managed conservatively due to severe comorbidities, 5 underwent primary closure, and 15 had application of Prolene (Ethicon Inc) mesh silo and serial reduction. Five died, including two managed conservatively, none primarily of the exomphalos. Survivors were followed up for 38 months (2-71). Cardiac anomalies were present in 20 (91%) patients: 8 had minor and 12 major anomalies. Twelve (55%) patients had other anomalies. Primary closure was associated with shorter length of stay (13 vs. 85 days, p = 0.02), but infants had similar lengths of intensive care stay, duration of parenteral feeds, and time to full feeds. Infants with cardiac anomalies had shorter times to full closure (28 vs. 62 days, p = 0.03), but other outcomes were similar. CONCLUSION: Infants whose defect can be closed primarily have a shorter length of stay, but other outcomes are similar. Infants with more significant abdominovisceral disproportion are managed with staged closure; the presence of major cardiac anomalies does not affect surgical outcome.

DNAAF1 links heart laterality with the AAA+ ATPase RUVBL1 and ciliary intraflagellar transport.

DNAAF1 (LRRC50) is a cytoplasmic protein required for dynein heavy chain assembly and cilia motility, and DNAAF1 mutations cause primary ciliary dyskinesia (PCD; MIM 613193). We describe four families with DNAAF1 mutations and complex congenital heart disease (CHD). In three families, all affected individuals have typical PCD phenotypes. However, an additional family demonstrates isolated CHD (heterotaxy) in two affected siblings, but no clinical evidence of PCD. We identified a homozygous DNAAF1 missense mutation, p.Leu191Phe, as causative for heterotaxy in this family. Genetic complementation in dnaaf1-null zebrafish embryos demonstrated the rescue of normal heart looping with wild-type human DNAAF1, but not the p.Leu191Phe variant, supporting the conserved pathogenicity of this DNAAF1 missense mutation. This observation points to a phenotypic continuum between CHD and PCD, providing new insights into the pathogenesis of isolated CHD. In further investigations of the function of DNAAF1 in dynein arm assembly, we identified interactions with members of a putative dynein arm assembly complex. These include the ciliary intraflagellar transport protein IFT88 and the AAA+ (ATPases Associated with various cellular Activities) family proteins RUVBL1 (Pontin) and RUVBL2 (Reptin). Co-localization studies support these findings, with the loss of RUVBL1 perturbing the co-localization of DNAAF1 with IFT88. We show that RUVBL1 orthologues have an asymmetric left-sided distribution at both the mouse embryonic node and the Kupffer's vesicle in zebrafish embryos, with the latter asymmetry dependent on DNAAF1. These results suggest that DNAAF1-RUVBL1 biochemical and genetic interactions have a novel functional role in symmetry breaking and cardiac development.

Wound Morbidity in Minimally Invasive Anterior Component Separation Compared to Transversus Abdominis Release.

BACKGROUND: Transversus abdominis release is a novel approach for myofascial advancement in ventral hernia repair and has been hypothesized to have lower rates of wound complication than anterior component separation. METHODS: Patients who had a ventral hernia repair with either transversus abdominis release or minimally invasive anterior component separation from January of 2010 to January of 2016 were enrolled in this retrospective cohort study. Patient characteristics were collected through chart review. Primary outcomes were operative time and wound complications. Multiple linear/Poisson regression and Fisher's exact test were used to determine statistical significance. RESULTS: Of 142 patients analyzed, 75 subjects underwent Butler minimally invasive anterior component separation and 67 underwent transversus abdominis release. There were no differences in baseline characteristics between groups, except that the anterior component separation group had more immunosuppressed patients (35 percent versus 19 percent). Median operative time for anterior component separation was 6.3 hours versus 6.1 hours for transversus abdominis release (p = 0.6). Overall wound complications did not differ between the groups (p = 0.5). Compared with anterior component separation, transversus abdominis release had a similar incidence of seroma/hematoma (relative risk, 0.9; 95 percent CI, 0.5 to 1.7), wound infection (relative risk, 1.1; 95 percent CI, 0.5 to 2.2), and mesh infection (relative risk, 0.7; 95 percent CI, 0.2 to 3.4). Hernia recurrence was 12 percent for anterior component separation and 6 percent for transversus abdominis release (relative risk, 0.6; 95 percent CI, 0.2 to 1.7). Reoperation was required in 19 percent of anterior component separation and 12 percent of transversus abdominis release subjects (relative risk, 0.5; 95 percent CI, 0.2 to 1.2). CONCLUSIONS: Transversus abdominis release patients had similar operative times, wound complications, reoperations, and hernia recurrences compared with Butler minimally invasive anterior component separation patients. This contemporary comparison helps inform operative decisions for reconstructive surgeons. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

The impact of bariatric surgery on esophageal function.

Obesity is a worldwide epidemic. There is increasing evidence that obesity is associated with benign gastroesophageal disease, including gastroesophageal reflux disease (GERD) and esophageal dysmotility. Bariatric surgery-including sleeve gastrectomy, gastric bypass, and adjustable gastric band placement-can effectively result in weight loss and control of obesity-related conditions, including GERD. However, there is increasing evidence that bariatric surgery itself can have a deleterious effect on esophageal function. In this review, we address the effect of obesity and bariatric surgery on esophageal dysfunction.

Outcome of noncardiac surgery in children with congenital heart disease performed outside a cardiac center.

OBJECTIVE: The objective of this study was to review the outcome of children with congenital heart disease (CHD) undergoing noncardiac surgery requiring general anesthesia (GA) in a tertiary pediatric center between January 2010 and December 2012. STUDY DESIGN: A retrospective case note review of children <16years of age with confirmed CHD undergoing a surgical or interventional procedure requiring GA was performed. Patients were categorized into three risk groups according to White and Peyton's anesthetic risk classification of children with CHD undergoing noncardiac surgery [Critical Care and Pain 2012;12:17-22]. RESULTS: 117 children with CHD were identified with a total of 240 procedures conducted. 36 procedures were conducted in the high-risk group, 135 in the intermediate-risk group, and 69 in the low-risk group. 40% of these were major operations such as small bowel and colonic procedures. Overall mortality rate at 7days and 30days was 0% and 0.4%, respectively, with a 1% mortality rate in minor procedures and 0% mortality rate in major procedures. There were no unexpected deaths. 17% of procedures resulted in complications. A higher rate of complications was recorded in emergency procedures. 17% of these procedures required admission to the intensive care unit, with the highest admissions rate in the high-risk group. The median duration of hospital stay for the whole cohort was 1day (range of 0-71days). CONCLUSION: Our study shows that procedures requiring GA can be safely conducted on children from any of the three risk groups in a nonspecialist cardiac center provided that there is close liaison and careful planning between the different specialties.

The use of crural relaxing incisions with biologic mesh reinforcement during laparoscopic repair of complex hiatal hernias.

INTRODUCTION: Laparoscopic hiatal hernia repair has a better chance of success if the hiatus is closed without tension. This study attempts to answer the following questions: (1) What is the rate of hiatal hernia recurrence in patients who undergo hiatal closure with diaphragmatic relaxing incisions? (2) Can biologic mesh be safely substituted for synthetic mesh as coverage of the relaxing incisions? METHODS: We identified all patients who underwent laparoscopic hiatal hernia repair at our institution between 2007 and 2013 and reviewed their clinical records. Radiologic recurrence was identified by an experienced radiologist and defined as the presence of any abdominal contents located above the diaphragm on esophagram. Clinical recurrence was defined as little or no improvement in symptoms, the development of a new symptom, or the need for medical, endoscopic, or surgical treatment of postoperative symptoms. RESULTS: A minimum of 6 months of radiologic and clinical follow-up was available for 146 (40 %) patients, including 16 with relaxing incisions. There were 66 (45 %) recurrent hernias detected on esophagram. There was no difference in the rate of recurrent hiatal hernia among the three groups: Primary closure of the hiatus (21/36 [58 %]), primary closure with biologic mesh reinforcement (36/94 [38 %]), and relaxing incision with biologic mesh reinforcement (9/16 [56 %]; p = 0.428). Two reoperations were performed on patients who underwent left relaxing incisions and developed symptomatic diaphragmatic hernias through the left relaxing incisions. There were no complications associated with use of biologic mesh at the hiatus. CONCLUSIONS: Rate of recurrent hiatal hernia is similar between patients who undergo diaphragmatic relaxing incisions and patients who undergo primary hiatal closure. Relaxing incisions can be safely performed on either crus; however, biologic mesh should not be used to patch a left-sided relaxing incision due to the risk of developing a diaphragmatic hernia.

Politics and Universal Health Coverage--The Post-2015 Global Health Agenda.

What political, social, and economic factors allow a movement toward universal health coverage to take hold in some low- and middle-income countries? Can we use that knowledge to help other such countries achieve health care for all?

The management of conjoined twins: Cardiology assessment.

Structural cardiac defects occur in at least 1 twin in about 75% of conjoined twins with thoracic level fusion. Outcomes after surgical separation of thoracic level conjoined twins have been favorable when the hearts have been separate. However, even in this situation, the outlook is poor for an individual twin with an important cardiac defect. Arterial anastomosis between twin circulations is an important additional consideration, with poor outcomes for perfusion recipient twins. Surgical separation is contraindicated when ventricular level cardiac fusion exists. Cardiac assessment is a key component of prenatal counseling.

Surgical treatment of gastroesophageal reflux disease.

Operative treatment of GERD has become more common since the introduction of LARS. Careful patient selection based on symptoms, response to medical therapy, and preoperative testing will optimize the chances for effective and durable postoperative control of symptoms. Complications of the LARS are rare and generally can be managed without reoperation. When reoperation is necessary for failed antireflux surgery, it should be performed by high-volume gastroesophageal surgeons.
