Gastroesophageal Reflux Disease in Obesity: Bariatric Surgery as Both the Cause and the Cure in the Morbidly Obese Population.

Gastrointestinal reflux disease (GERD) is a chronic, highly prevalent condition in the United States. GERD can significantly impact quality of life and lead to complications including aspiration pneumonia, esophageal stricture, Barrett's esophagus (BE) and esophageal cancer. Obesity is a risk factor for GERD, which often improves with weight loss and bariatric surgery. Though the incidence of bariatric surgery, in particular, minimally invasive sleeve gastrectomy, has risen in recent years, emerging data has revealed that the severity or new onset of GERD may follow bariatric surgery. We performed a literature review to provide a detailed analysis of GERD with an emphasis on bariatric surgery as both the cure and the cause for GERD in the morbidly obese population. We also describe the pathophysiological mechanisms, management approach and treatment strategies of GERD following bariatric surgery.

Bariatric surgery-what the ophthalmologist needs to know.

The incidence of bariatric surgery is increasing due to obesity being one of our top public health challenges. As such, bariatric-related ophthalmic changes are a potentially new clinical area of knowledge, with increasing published evidence on post-bariatric complications experienced by patients and identified by clinicians. We reviewed the available literature and summarised the different complications and potential recommendations. A search strategy was conducted with PubMed, Cochrane, Medline, Embase, Allied and Complementary Medicine and DH-DATA databases to look for papers answering our research question: “What are the ophthalmological complications for patients after bariatric surgery?”. Our search gave a total of 59 relevant papers. Bariatric surgery, particularly subtypes that cause direct bypass of nutrients from the stomach, lead to nutritional deficiencies. Vitamin A, crucial for proper functioning of body systems and specialised cells, manifests ophthalmologically as corneal ulceration, nyctalopia, conjunctival xerosis and more. Thiamine levels are also depleted, leading to Wernicke’s Encephalopathy. Pre-existing diabetic retinopathy is also noted to worsen sub acutely, although evidence is conflicting. Patients undergoing surgery to treat idiopathic intracranial hypertension would have reduced IOP and resolving papilloedema. Other comorbidities of obesity like HBA1C levels, obstructive sleep apnoea, and metabolic syndrome also resolve post-surgery. History taking remains the cornerstone of medical practice. From the evidence, we suggest consideration of pre-surgery screening for ophthalmic pathology and post-operative monitoring of disease progression. Real-world data needs to continuously be analysed to create definitive management pathways that can help clinicians recognise ophthalmic complications early, improving patient outcomes.

Care of Pregnant Women With a History of Bariatric Surgery

In recent years, the incidence of bariatric surgery has increased among women of reproductive age. Health care providers should be knowledgeable about the impact bariatric surgery has on women and developing fetuses to effectively provide care from preconception through postpartum. Although pregnancy in women with normal weight or with excess weight after bariatric surgery has better outcomes when compared to pregnancy complicated by obesity, it is associated with complications such as nutritional deficiencies, low birth weight, and fetal growth restriction. Consequently, a multidisciplinary approach is recommended to ensure adequate nutrition, counseling, and screening before and during pregnancy. This article summarizes evidence regarding pregnancy complications that may occur in women with a history of bariatric surgery and presents a nursing, advanced practice nursing, and midwifery plan of care for these women before, during, and after pregnancy.

Endoscopic approach for the treatment of bariatric surgery complications

The incidence of bariatric surgery is increasing exponentially. The number of bariatric surgeries performed in the United States has significantly increased in the past decades. Complications of bariatric surgery can present days to years postoperatively. Advances in endoscopic procedures and technology has made it possible to address many complications endoscopically. We describe the most common complications after bariatric surgery and the endoscopic treatment options available to date.

Pregnancy Management After Bariatric Surgery.

Obesity is a source of major morbidity and mortality and is a growing concern worldwide. Maternal obesity is associated with increased maternal and fetal risks during pregnancy. Bariatric surgery has emerged as one of the most sustainable treatments for severe obesity and its comorbidities. Patients who have undergone bariatric surgery often experience drastic improvements in hypertension and diabetes. It is not surprising, therefore, that the incidence of bariatric surgery is increasing, particularly in women of childbearing age. In fact, many women undergoing bariatric surgery plan to become pregnant in the future. Bariatric surgery may have a beneficial effect on rates of fetal macrosomia, gestational diabetes, hypertension, and preeclampsia. Conversely, studies have showed that bariatric surgery may increase the risk of small for gestational age infants and preterm birth. Given its rising incidence, it is important that physicians be able to thoroughly and accurately counsel and treat patients who plan to, or do, become pregnant after bariatric surgery.

Wernicke Encephalopathy

Introduction and PurposeThis paper reviews the complaints and associated symptoms/consequences of lacking essential nutrients and vitamins in our central and peripheral nervous systems. This has become important as there has been a rise in malnutrition following the increasing incidence of bariatric surgery for obesity.MethodsA case report example involving review of the clinical presentation and treatment.ResultsA 30-year-old Caucasian woman who had gastric sleeve surgery did not take the recommended capsules as they were too large to swallow. She noted diplopia and oscillopsia 2 months later, which led her to have full orthoptic and neuro-ophthalmic evaluations. After being treated with chewable vitamins with thiamine, she noted a tremendous improvement in her symptoms.ConclusionWernicke encephalopathy is a disease that was seen more in the 1940s and 1950s, following war times and mostly in underdeveloped countries. However, with the increasing utilization of bariatric surgery for obesity, neurological offices are seeing more patients with neurological impairments. We recommend inquiring about any obesity surgery in one's history and including Wernicke encephalopathy in possible differential diagnoses in those patients who have a recent onset of strabismus or nystagmus, altered mental status, and/or gait ataxia.

Incidence of bariatric surgery and postoperative outcomes: a population‐based analysis in Western Australia

To investigate the incidence of bariatric surgery and postoperative outcomes in a population-based cohort of patients in Western Australia over a 17-year period. A population-based incidence study of all bariatric procedures (n=1403) performed in WA hospitals over the period 1988-2004, based on hospital morbidity and death data from the WA Data Linkage System. Changes in incidence of bariatric procedures over time; mortality and complications within 30 days after surgery; survival rates after surgery relative to age-, sex-, and period-matched survival rates in the general population; factors predictive of re-admission to hospital. The incidence of bariatric surgery increased from 1.2 procedures per 100,000 person-years in 1988 to 24.2 procedures per 100,000 person-years in 2004. Although some of this was ascribed to a rising prevalence of obesity generally, there was a 13-fold increase in the bariatric procedure rate within the obese population itself. At 5 years, the relative survival rate in bariatric patients was the same as the survival rate in the general population. Within the 30-day postoperative period, mortality was low (0.07%) and 9.6% of patients experienced complications. Those who had bypass-type procedures were more likely to be re-admitted within 30 days than those who had gastric reduction procedures (adjusted hazard ratio, 5.80 [95% CI, 3.42-9.84]). The use of bariatric surgery increased 20-fold over the study period. Relative survival after surgery was in line with population norms. The observed low mortality rates and moderate level of complications are similar to findings in other studies in which the proportion of reduction procedures has been high.
