Background: Household air pollution (HAP) is a leading environmental risk factor accounting for about 1.6â million premature deaths mainly in low- and middle-income countries (LMICs). However, no multicounty randomized controlled trials have assessed the effect of liquefied petroleum gas (LPG) stove intervention on HAP and maternal and child health outcomes. The Household Air Pollution Intervention Network (HAPIN) was the first to assess this by implementing a common protocol in four LMICs. Objective: This manuscript describes the implementation of the HAPIN data management protocol via Research Electronic Data Capture (REDCap) used to collect over 50â million data points in more than 4000 variables from 80 case report forms (CRFs). Methods: We recruited 800 pregnant women in each study country (Guatemala, India, Peru, and Rwanda) who used biomass fuels in their households. Households were randomly assigned to receive LPG stoves and 18â months of free LPG supply (intervention) or to continue using biomass fuels (control). Households were followed for 18â months and assessed for primary health outcomes: low birth weight, severe pneumonia, and stunting. The HAPIN Data Management Core (DMC) implemented identical REDCap projects for each study site using shared variable names and timelines in local languages. Field staff collected data offline using tablets on the REDCap Mobile Application. Results: Utilizing the REDCap application allowed the HAPIN DMC to collect and store data securely, access data (near real-time), create reports, perform quality control, update questionnaires, and provide timely feedback to local data management teams. Additional REDCap functionalities (e.g. scheduling, data validation, and barcode scanning) supported the study. Conclusions: While the HAPIN trial experienced some challenges, REDCap effectively met HAPIN study goals, including quality data collection and timely reporting and analysis on this important global health trial, and supported more than 40 peer-reviewed scientific publications to date.

OBJECTIVES: The ribosomal protein S14 (RPS14) gene located at 5q33 codes for a protein involved in ribosomal biogenesis. The RPS14 gene has a length of 5.9 kb of DNA comprising 5 exons and 4 introns. It is possible that RPS14 is involved in the formation of pre-RNA 18s, an intermediate RNA that serves for the formation of the 40S small subunit of the ribosome. RPS14 haploinsufficiency (HI) produces alterations in intermediate RNA levels (pre-RNA 30S/18SE/18S), which are found in del(5q) MDS. In addition, RPS14 haploinsufficiency results in the formation of the MDM2 (double minute mouse E3 ubiquitin ligase)-RP (ribosomal protein) complex that prevents the MDM2-p53 interaction, generating an accumulation of p53 levels. This accumulation produces cell cycle arrest, impaired DNA repair, senescence, and apoptosis. RPS14 haploinsufficiency has been seen in MDS. Altered expression levels of RPS14 have also been reported in glioma, colorectal cancer, hepatocellular carcinoma, breast cancer, renal cell carcinoma, and primary myelofibrosis.

Domestic, or household-level, open burning of plastic waste is a source of air pollutants and greenhouse gases that are often neglected in emission inventories. Domestic open burning is a considerable concern in Guatemala due to the lack of access to waste collection services, particularly in rural areas. This paper offers the first attempt to estimate emissions from the domestic open burning of waste at the city and departmental levels in Guatemala. Data were collected from the Xalapán region of Jalapa, Guatemala and analyzed to determine the change in plastic waste generation over time as well as the socioeconomic factors that may affect the extent of plastic waste generation and burning. The annual per capita masses of plastic waste burned were used to estimate emissions from domestic open burning of plastic waste in the region of Xalapán, the cities of Jutiapa and Guatemala city, and all 22 departments in Guatemala. Our results show that rural areas burn more waste domestically, likely because of a lack of access to waste collection, and 30.4% of OC, 24.0% of BC, 23.6% of PM2.5, and 2.4% of CO2 emissions in Guatemala may not be accounted for by excluding open plastic burning as a source.

Introducción: El síndrome de túnel de carpo es una neuropatía del nervio mediano muy frecuente en la población. Para los usuarios de sillas de ruedas hay mayor riesgo biomecánico por utilizar reiteradamente la muñeca en la propulsión de este vehículo. Objetivo: Analizar los factores biomecánicos de la silla de ruedas que inciden en el desarrollo del síndrome de túnel del carpo. Métodos: Se realizó una revisión sistemática con términos Mesh en bases de datos como Embase, Pubmed, Google Acedemics, Scielo desde 1988 hasta 2021. Se revisaron más de 200 artículos y por su impacto clínico, se seleccionaron 52 para la revisión. Resultados: El 43 % de los usuarios de silla de ruedas presentan dolor en la muñeca y prevalece como diagnóstico el síndrome de túnel del carpo. La posición de la muñeca en la propulsión genera un aumento de presión en el túnel carpiano lo que condiciona la lesión del nervio mediano. Existen factores de riesgo como el género femenino, las pendientes, el terreno irregular, la vibración, la altura del asiento y el peso del paciente. Entender correctamente las fases de la autopropulsión con sus cuatro patrones, más una prescripción adecuada y los aditamentos necesarios para la silla de ruedas pueden disminuir el riesgo de padecer el síndrome de túnel del carpo. Conclusión: Es importante involucrar de manera activa a los profesionales de la salud en la implementación de estrategias para el entrenamiento, prescripción y uso correcto de la silla de ruedas y con ello prevenir el padecimiento de el síndrome de túnel carpiano.
Introduction: Carpal tunnel syndrome is a very common neuropathy of the median nerve in the population. For wheelchair users, there is a greater biomechanical risk for repeatedly using the wrist to propel this vehicle. Objective: To analyze the biomechanical factors of the wheelchair affecting the development of carpal tunnel syndrome. Methods: A systematic review with Mesh terms was carried out in databases such as Embase, Pubmed, Google Acedemics, Scielo from 1988 to 2021. More than 200 articles were reviewed and due to their clinical impact, 52 were selected for the review. Results: 43% of wheelchair users have wrist pain and carpal tunnel syndrome prevails as a diagnosis. The position of the wrist in the propulsion generates an increase in pressure in the carpal tunnel conditioning the injury of the median nerve. There are risk factors such as female gender, angles, uneven terrain, vibration, seat height and patient weight. Proper understanding the phases of self-propulsion with its four patterns, plus correct prescription and necessary wheelchair attachments can decrease the risk of carpal tunnel syndrome. Conclusion: It is important to actively involve health professionals in the implementation of strategies for training, prescription and correct use of the wheelchair and thereby prevent carpal tunnel syndrome.

INTRODUCCIÓN: El dolor lumbar es una condición de alta prevalencia en la población general. La gestación genera cambios fisiológicos que favorecen la aparición de síntomas dolorosos que pueden comprometer la calidad de vida. MÉTODO: Revisión de la literatura con términos MeSH en inglés y español en las bases de datos Embase, PubMed, Lilacs, Sage, Google Academics y Scielo desde el año 1994 hasta el año 2021. Se encontraron 74 artículos y fueron seleccionados 50, basados en su impacto clínico. RESULTADOS: El dolor lumbar afecta a más del 50% de las mujeres embarazadas. Existen antecedentes gineco-obstétricos que pueden intervenirse para disminuir el riego o la intensidad de los síntomas. El diagnóstico es clínico, pero puede asociarse a imágenes diagnósticas cuando se sospechan condiciones de riesgo. El tratamiento se basa en intervenciones no farmacológicas como ejercicio y terapia física, pero pueden utilizarse algunos medicamentos e intervenciones en dolor según su riesgo-beneficio materno y fetal. CONCLUSIONES: El dolor lumbar en el embarazo es muy frecuente y debe ser conocido, diagnosticado y tratado por los profesionales de la salud que atienden esta población, dentro de un equipo multidisciplinario de tratamiento.
INTRODUCTION: Low back pain is a condition of high prevalence in the general population. Gestation generates physiological changes that favor the appearance of painful symptoms that can compromise the quality of life. METHOD: Review of the literature with MeSH terms in English and Spanish in the databases Embase, PubMed, Lilacs, Sage, Google Academics and Scielo from the year 1994 to the year 2021. Seventy-four articles were found and 50 were selected based on their clinical impact. RESULTS: Low back pain affects more than 50% of pregnant women. There are gyneco-obstetric antecedents that can be intervened to reduce the risk or intensity of symptoms. The diagnosis of this entity is clinical, but it can be associated with diagnostic imaging when risk conditions are suspected. Treatment is based on non-pharmacological interventions such as exercise and physical therapy, but some medications and pain interventions can be used according to their risk of maternal and fetal benefit. CONCLUSIONS: Low back pain in pregnancy is very frequent, it should be known, diagnosed, and treated by health professionals who care for this population, based on a multidisciplinary treatment team.

OBJECTIVE: The mortality and morbidity pattern for respiratory diseases was determined in a cohort of 1752 Swedish foundry workers, particularly for respirable silica dust exposure. METHODS: The morbidity follow-up in the Swedish National Non-primary Outpatient Register covered 2001 to 2017 (NPR; specialist not in care patients), the mortality from the National Causes of Death Register covered 2001 to 2017. Cumulative exposures to silica and dust were determined. RESULTS: The morbidity in COPD showed significantly increased risk for all exposure groups, as did silicosis in the high exposure group, these cases corresponded to silica exposure levels below 0.05 mg/m3. The mortality of all causes and respiratory diseases was significantly increased by cumulative silica exposure in the high exposure group. CONCLUSIONS: Significantly increased morbidity for respiratory diseases and COPD was determined at silica exposure levels below the current Swedish OEL.

OBJECTIVE: The objective of this study is to evaluate the impact of high-deductible health plans on elective surgery (tonsillectomy) in the pediatric population. STUDY DESIGN: Cross-sectional study. SETTING: Health claims database from a third-party payer. METHODS: Data were reviewed for children up to 18 years of age who underwent tonsillectomy or arm fracture repair (nonelective control) from 2016 to 2019. Incidence of surgery by health plan deductible (high, low, or government insured) and met or unmet status of deductibles were compared. RESULTS: A total of 10,047 tonsillectomy claims and 9903 arm fracture repair claims met inclusion and exclusion criteria. The incidence of tonsillectomy was significantly different across deductible plan types. Patients with met deductibles were more likely to undergo tonsillectomy. In patients with deductibles ≥$4000, a 1.75-fold increase in tonsillectomy was observed in those who had met their deductible as compared with those who had not. These findings were not observed in controls (nonelective arm fracture). For those with met deductibles, those with high deductibles were much more likely to undergo tonsillectomy than those with low, moderate, and government deductibles. Unmet high deductibles were least likely to undergo tonsillectomy. CONCLUSIONS: Health insurance plan type influences the incidence of pediatric elective surgery such as tonsillectomy but not procedures such as nonelective repair of arm fracture. High deductibles may discourage elective surgery for those deductibles that are unmet, risking inappropriate care of vulnerable pediatric patients. However, meeting the deductible may increase incidence, raising the question of overutilization.

PURPOSE: To compare the effectiveness of COVID-19 mitigation strategies in two homeless shelters in Massachusetts during the pandemic. METHODS: We conducted a prospective cohort study that followed guests in two Massachusetts homeless shelters between March 30 and May 13, 2020, which adopted different depopulation strategies. One set up temporary tents in its parking lot, while the other decompressed its guests to a gym and a hotel. The outcome was assessed by comparing the odds ratios of positive SARS-CoV-2 RT-PCR assays. RESULTS: Guests residing at the shelter that used temporary tents had 6.21 times (95% CI = 1.86, 20.77) higher odds of testing positive for SARS-CoV-2 at follow-up after adjusting for loss to follow up, age, gender, and race. The daily COVID-19 symptoms checklist performed poorly in detecting positive infection. CONCLUSIONS: The study highlights the importance of depopulating shelter guests with stable and adequate indoor space to prevent SARS-CoV-2 transmission. Daily temperature and symptom checks should be combined with routine testing. With the rising homelessness due to mass unemployment and eviction crisis, our study supports further governmental assistance in decompressing homeless shelters during this pandemic.

OBJECTIVE: Understand opioid-prescribing patterns in otologic surgery and the difference in opioid use between transcanal and postauricular surgery. STUDY DESIGN: Prospective survey. SETTING: Multihospital network. PATIENTS: All patients undergoing otologic surgery from March 2017 to January 2019. INTERVENTION: Patients undergoing otologic surgery were surveyed regarding postoperative opioid use and their level of pain control. Patients were divided by surgical approach (transcanal vs. postauricular). Those who underwent mastoid drilling were excluded. Narcotic amounts were converted to milligram morphine equivalents (MME) for analysis. MAIN OUTCOME MEASURES: Amount of opioid was calculated and compared between the two groups. Mann-Whitney U test and Chi-square testing were used for analysis. RESULTS: Fifty-five patients were included in the analysis; of these 18 (33%) had a postauricular incision. There was no difference in age (pâ=â0.85) or gender (pâ=â0.5) between the two groups. The mean amount of opioid prescribed (MME) in the postauricular and transcanal groups was 206.4 and 143 (pâ=â0.038) while the mean amount used was 37.7 and 37.5 (pâ=â0.29) respectively. There was no difference in percentage of opioid used (pâ=â0.44) or in patient-reported level of pain control (pâ=â0.49) between the two groups. CONCLUSION: Patients in both the transcanal and postauricular groups used only a small portion of their prescribed opioid. There was no difference in the amount of opioid used or the patient's reported level of pain control based on the approach. Otologic surgeons should be aware of these factors to reduce narcotic diversion after ear surgery.

OBJECTIVE: Third-party payers advocate for prior authorization (PA) to reduce overutilization of health care resources. The impact of PA in elective surgery is understudied, especially in cases where evidence-based clinical practice guidelines define operative candidacy. The objective of this study is to investigate the impact of PA on the incidence of pediatric tonsillectomy. STUDY DESIGN: Cross-sectional study. SETTING: Health claims database from a third-party payer. METHODS: Any pediatric patient who had evaluation for tonsillectomy from 2016 to 2019 was eligible for inclusion. A time series analysis was used to evaluate the change in incidence of tonsillectomy before and after PA. Lag time from consultation to surgery before and after PA was compared with segmented regression. RESULTS: A total of 10,047 tonsillectomy claims met inclusion and exclusion criteria. Female patients made up 51% of claims, and the mean age was 7.9 years. Just 1.5% of claims were denied after PA implementation. There was no change in the incidence of tonsillectomy for all plan types (P = .1). Increased lag time from consultation to surgery was noted immediately after PA implementation by 2.38 days (95% CI, 0.23-4.54; P = .030); otherwise, there was no significant change over time (P = .98). CONCLUSION: A modest number of tonsillectomy claims were denied approval after implementation of PA. The value of PA for pediatric tonsillectomy is questionable, as it did not result in decreased incidence of tonsillectomy in this cohort.

BACKGROUND: There is variability in opioid prescription patterns among surgeons performing thyroidectomy. Thus, the aim of this study is to evaluate opioid prescription rates and opioid use among hemithyroidectomy (HT) and total thyroidectomy (TT) patients. DESIGN/METHOD: An electronic postoperative survey was distributed to assess opiate use among patients undergoing HT/TT. Groups were compared using t-tests, chi-square tests, and analysis of variance. RESULTS: A total of 142 opiate naïve patients were included, of which 75 (52.8%) underwent HT and 67 (47.1%) underwent TT. The mean number of tablets prescribed was 21.3 (HT = 22.1, TT = 20.4; P = 0.3), with a mean of 14.1 tablets unused after surgery (HT = 13.2 tablets, TT = 15.0 tablets; P = 0.44). The mean morphine milligram equivalent (MME) prescribed was 150.1 mg (HT = 159.0 mg, TT = 140.2 mg; P = 0.3), with a mean of 98.2 MME unused after surgery (HT = 93.7 mg, TT = 103.2 mg; P = 0.6). CONCLUSIONS: Opioids are overprescribed after thyroid surgery. Avoidance of overprescribing is vital in mitigating the current opioid crisis.

OBJECTIVES: The objective of this study was to evaluate surgeon-prescribing patterns and opioid use for patients undergoing common otolaryngology surgeries. We hypothesized that there was little consistency across surgeons in prescribing patterns and that surgeons prescribed significantly more opioids than consumed by patients. METHODS: E-mail-based surveys were sent to all postoperative patients across a 23-hospital system. The survey assessed quantity of opioids consumed postoperatively, patient-reported pain control, and methods of opioid disposal. We compared patient-reported opioid consumption to opioids prescribed based on data in the electronic data warehouse. RESULTS: There was wide variation in prescribing between providers both in the quantity and type of opioids prescribed. Patients used significantly less opioids than they were prescribed (10 vs. 30 tablets, P < 0.001) for both opioid-exposed and opioid-naïve patients. More than 75% of patients had excess opioids remaining. CONCLUSION: Opioids are consistently overprescribed following ambulatory head and neck surgery. Otolaryngologists have an important role in the setting of the national opioid epidemic and should be involved in efforts to reduce excess opioids in their community. LEVEL OF EVIDENCE: 4 Laryngoscope, 130: 1913-1921, 2020.

Introduction: Mentorship is essential for students considering a future in academic medicine. Mentoring is recognized as one of the most important factors in determining career success through enhancing trainees' goals and productivity. An effective mentoring relationship can drive trainees' goals to fruition by providing support so that opportunistic risk can be taken and failures can be reevaluated into learning experiences. Mentorship has such importance that it was deemed mandatory in education by the Liaison Committee on Medical Education and the Accreditation Council for Graduate Medical Education. Moreover, mentoring can play a significant role in helping to diversify the academic medicine workforce. Methods: This 60-minute workshop utilizes a didactic PowerPoint presentation and small-group role-play exercise to introduce participants to the importance of mentoring in the development of academic medicine careers and to provide instruction on establishing effective meetings with prospective mentors. Faculty facilitated the workshop at nine regional academic medicine conferences held across the country. Results: Eighty-seven diverse participants completed an evaluation form. In comparing pre- and postworkshop responses, there was a statistically significant increase in confidence to "Find a mentor for a career in academic medicine" (2.29 vs. 3.26, p < .001) and "Have a successful relationship with an academic medicine mentor" (2.52 vs. 3.38, p < .001). Moreover, more than 85% agreed or strongly agreed that the workshop's learning objectives were met. Discussion: Trainees from diverse backgrounds gained crucial insight into the importance of mentorship and techniques on how to establish and maintain mentors while pursuing an academic medicine career.

BACKGROUND: The measurement of adipose tissue (AT) depots in vivo requires expensive imaging methods not accessible to most clinicians and researchers. The study aim was to derive mathematical models to predict total AT (TAT) and subdepots from total body fat derived from a dual-energy X-ray absorptiometry (DXA) scan. METHODS: Models were developed to predict magnetic resonance imaging-derived TAT and subdepots subcutaneous AT, visceral AT, and intermuscular AT from DXA total body fat (Fat(DXA)) using cross-sectional data (time 0 (T0)) and validated results using 1 (T1) and 2 (T2) y follow-up data. Subjects were 176 multiethnic healthy children ages 5-17 y at T0. Twenty-two were measured at T1 and T2. TAT was compared with Fat(DXA). RESULTS: At T0, TAT was greater than Fat(DXA) (12.5 ± 8.4 vs.12.0 ± 9.4 kg; P < 0.0001), with a quadratic relationship between TAT and Fat(DXA) that varied by sex. Predicted mean TATs were not different from measured TATs: T1: (9.84 ± 4.45 kg vs. 9.50 ± 4.37 kg; P = 0.11); T2: (12.94 ± 6.75 kg vs. 12.89 ± 7.09 kg; P = 0.76). The quadratic relationship was not influenced by race or age. CONCLUSION: In general, the prediction equations for TAT and subdepots were consistent with the measured values using T1 and T2 data.

BACKGROUND: The aim of the present study was to report the outcomes of bariatric surgery in patients >70 years of age at a community hospital in the United States. METHODS: A retrospective review was performed of prospectively collected data from patients aged >70 years who had undergone bariatric surgery at a single institution from 2002 to 2008. The data analyzed included age, preoperative and postoperative weight and body mass index, postoperative complications, and co-morbidities. RESULTS: Of 42 patients aged >70 years who underwent bariatric surgery, 22 patients (52.4%) had undergone laparoscopic gastric banding, 12 patients (28.6%) laparoscopic sleeve gastrectomy, and 8 patients (19%) laparoscopic Roux-en-Y gastric bypass. The mean preoperative weight and body mass index was 127.4 ± 25.5 kg and 46.8 ± 9.3 kg/m(2), respectively. The mean postoperative weight and body mass index was 100.2 ± 17 kg and 35.5 ± 5.4 kg/m(2), respectively. The median length of follow-up was 12 months (range 1-66). The mean percentage of excess weight loss was 47.7% at 12 months, with 73.1% follow-up data. Complications included wound infections in 4 patients (9.5%), band removal in 3 patients (7.1%), anastomotic leak in 1 patient (2.3%), and megaesophagus in 1 patient (2.3%). No mortality occurred. The postoperative use of medications for hypertension, hyperlipidemia, diabetes mellitus, and degenerative joint disease were reduced by 56%, 54%, 53%, 66%, and 50%, respectively. CONCLUSION: Bariatric surgery in carefully screened patients aged >70 years can be performed safely and can achieve modest improvement in co-morbidities.

BACKGROUND: Laparoscopic sleeve gastrectomy is a viable option that is becoming common in the management of morbid obesity. The aim of this study was to examine the effectiveness and safety of laparoscopic sleeve gastrectomy as a primary step for rapid weight loss in patients who required a second non-bariatric procedure. METHODS: After Internal Review Board approval and with adherence to HIPAA guidelines, we conducted a retrospective review of a prospectively collected database of all patients who underwent laparoscopic sleeve gastrectomy as a primary procedure for a second non-bariatric operation from November 2004 to September 2008 at the Bariatric and Metabolic Institute at Cleveland Clinic Florida. The data was reviewed for age, gender, percentage of excess weight loss (%EWL), preoperative and postoperative body mass index (BMI), morbidity, and mortality. Mean follow-up time was 7 months (range, 2 weeks-12 months). RESULTS: Laparoscopic sleeve gastrectomy was performed in 18 patients who needed a second non-bariatric procedure such as knee replacement surgery, recurrent incisional hernia repair, laminectomy of the lumbar spine, kidney transplant, anterior cervical discectomy, and nephrectomy. Mean preoperative weight and BMI were 124.9 kg (range, 95.5-172.3 kg) and 44.87 kg/m2 (range, 33.36-58.87 kg/m2), respectively. Mean postoperative weight and BMI were 99.2 kg (range, 68.2-132.2 kg) and 35.79 kg/m2 (range, 23.46-48.97 kg/m2), respectively. There were no conversions to an open procedure in this series. There was no morbidity or mortality in this series. CONCLUSIONS: In this small group, laparoscopic sleeve gastrectomy appears to be an effective and safe first surgical approach for rapid weight loss in high-risk patients that require a second non-bariatric procedure.

A true chylous effusion is defined as the presence of ascitic fluid with high fat (triglyceride) content, usually higher than 110 mg/dl. We report a case of chyloperitoneum following laparoscopic Roux-en-Y gastric bypass (LRYGB) in a 40-year-old patient who was admitted for surgery on May 31, 2007. On August 2008 an abdominal CT with contrast was ordered for chronic abdominal pain showing diffuse ascites as well as mesenteric adenitis. On September 2008, the patient was admitted to the hospital. An elective diagnostic laparoscopy was scheduled. A large amount of chylous fluid was found. Microscopic analysis came back negative. The patient made an uneventful recovery after surgery. To our knowledge, this is the first reported case of chylous ascites following LRYGB. Chyloperitoneum should be considered as a possible cause of ascites in patients with chronic small bowel obstruction following a LRYGB.

BACKGROUND: Obstructive sleep apnea is a common condition in the morbidly obese population. Many patients undergoing bariatric surgery require postoperative continuous positive airway pressure (CPAP) therapy. Few data have been published evaluating gastrointestinal anastomotic morbidity in patients receiving CPAP therapy immediately after laparoscopic Roux-en-Y gastric bypass (LRYGB). The objective of the present study was to examine the short-term morbidity of postoperative CPAP in patients after LRYGB in a research setting. METHODS: We retrospectively reviewed a prospectively collected database of 310 patients who underwent LRYGB from June 2005 to August 2006. The hospital and office charts and respiratory treatment records were reviewed from the completion of surgery until the first postoperative visit at 2 weeks. The data collected included age, gender, body mass index, presence of obstructive sleep apnea, in-patient CPAP use, and perioperative complications. Patients were divided into 2 groups: those who used immediate postoperative CPAP therapy and those who did not. Patients requiring revisional surgery and other bariatric procedures were excluded from the present series. RESULTS: Postoperative CPAP was required by 91 patients (29.3%) and 219 did not use CPAP (70.7%). The mean patient age was 47.2 and 43.9 years (P <.01), and the average body mass index was 52 and 46.4 kg/m(2) in the groups that did and did not require CPAP postoperatively, respectively (P <.0001). No anastomotic leaks occurred in either group, and the most common in-hospital complication, seen in 7 patients (2.2%), was basal atelectasis (3 in the postoperative CPAP group; P >.05), followed by wound infection in 4 patients overall (1.2%; 3 patients in the postoperative CPAP group; P >.05) and gastrointestinal bleeding in 1 patient (.32%) in the group without postoperative CPAP. The difference in overall morbidity, unrelated to the integrity of the anastomosis, between those who used CPAP postoperatively and those who did not was not significant (4.5% versus 3.6%, respectively; P >.05). CONCLUSION: The use of CPAP after LRYGB did not result in increased the morbidity in our patient series.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) can impair esophageal peristalsis and can also cause a lack of relaxation of the lower esophageal sphincter, possibly leading to esophageal dilation. The aim of the present study was to determine the incidence of megaesophagus, the role of preoperative manometry in predicting its occurrence, and the management of megaesophagus after gastric banding in the setting of a research clinic. METHODS: We performed a retrospective review of a prospectively collected database. A total of 257 patients underwent LAGB from January 2002 to December 2006. The incidence of megaesophagus, its relationship to the preoperative esophageal manometry and upper gastrointestinal series findings, and the treatment of patients with this complication were analyzed. RESULTS: Of the 257 patients, 5 (1.9%) presented with megaesophagus after gastric banding. The mean interval to development was 32 months (range 24-36). The diagnosis was made using the symptoms, signs, and upper gastrointestinal series findings. The preoperative esophageal manometry findings were normal in 4 (80%) of these 5 patients, and 1 patient (20%) had a nonspecific motility disorder. The mean age was 54.5 years (range 30-76). The mean preoperative weight was 127.1 kg (range 112.7-145.9), and the body mass index was 43.2 kg/m2 (range 41-49). In all cases, the management of megaesophagus was gastric band removal. All the patients improved partially after band deflation but required band removal because of continued symptoms. CONCLUSION: Megaesophagus is a possible late complication after LAGB. The preoperative manometry results cannot predict for its occurrence. The management of megaesophagus caused by LAGB requires, in most cases, band removal.
