For patients with BMI of However, we have self-pay options for those individuals who have struggled with obesity for a long time, especially those with obesity related health problems.

Obesity is a worldwide epidemic. Obese patients develop obesity-related comorbidities including type 2 diabetes mellitus T2DM , hypertension, dyslipidemia, coronary artery disease, certain types of cancer, and gastroesophageal reflux disease GERD [ 2 — 6 ]. Healthcare providers must consider a treatment's effect on weight loss, as well as its impact on obesity-related comorbidities. Bariatric surgery, in conjunction with intensive lifestyle interventions and medical treatments, has been shown to produce marked weight loss and improvement in many obesity-related comorbidities [ 7 ].

The Montreal Classification defines GERD as a condition that develops when reflux of stomach contents in the esophagus causes troublesome symptoms or complications [ 10 ]. Symptoms associated with GERD include heartburn, regurgitation, dysphagia, laryngitis, and chronic cough. Prolonged acid exposure within the esophagus can lead to histopathologic and structural changes such as peptic stricture and Barrett's esophagus. The fundamental inciting event in GERD is the retrograde movement of gastric contents into the esophagus [ 11 ].

A number of physiological factors increase the likelihood of this event, namely: transient lower esophageal sphincter relaxations [ 12 — 14 ], a hypotensive or relatively hypotensive lower esophageal sphincter LES [ 15 ], and anatomic disruption of the gastroesophageal junction e.

The interplay between these elements has not been well elucidated, although it has been suggested that transient lower esophageal sphincter relaxations are responsible for mild symptoms, and more severe symptoms are due to the other two factors [ 19 ].

Transient lower esophageal sphincter relaxations, a hypotensive LES, and hiatal hernia are associated with obesity. Ayazi et al. Wu et al. The diagnosis of GERD is imprecise as there is no gold standard [ 22 ]. Recently published practice guidelines state that a diagnosis of GERD can be established in the setting of typical symptoms [ 23 ]. Given the lack of gold standard in GERD diagnosis, evaluation of GERD includes a variety of modalities including hour esophageal pH monitoring, esophageal manometry, endoscopy, and symptom reporting [ 24 , 25 ].

Studies assessing GERD often use symptom reporting as a primary endpoint, though others focus on more objective measures such as esophageal pH monitoring.

SG was developed in as the initial procedure in a staged approach to patients with morbid obesity [ 26 ]. It was described as an isolated procedure in by Johnston et al. SG has gained popularity since then as a definitive bariatric surgical procedure [ 29 , 30 ].

SG involves resection of the greater curvature of the stomach and preservation of the pyloric valve and gastroesophageal junction. This maintains patency of the proximal alimentary tract and provides a restrictive and biochemical impetus for weight loss [ 31 — 33 ].

An advantage of SG compared to other bariatric procedures is that it does not involve an anastomosis. SG was initially considered a purely restrictive weight-loss procedure but there is newer evidence that alteration in gastrointestinal hormones plays a role. These changes are manifested by a decrease in endogenous ghrelin a hormone associated with hunger production [ 34 ] and decreased gastric and small bowel transit times [ 35 ]. The measured increase in GERD prevalence ranged from 2.

There was marked heterogeneity between the studies in regard to a number of factors including preoperative BMI, method of evaluating GERD, exclusion criteria, length of follow-up, and operative technique. Two studies, Arias et al. Arias et al. Braghetto et al.

Followup was not clearly reported and it is not stated whether the study was conducted prospectively. It is reasonable to assume that the modest 2. The Both works of Carter et al.

Carter et al. Data for GERD was presented in two categories: early symptoms occurring in the first 30 days and late symptoms occurring after 30 days. Howard et al. Himpens et al. An initial increase at one year, followed by a decrease at three years, and an increase at six years. Other studies lack the follow-up necessary to assess for this third phase.

For example, Melissas et al. The work of Nocca et al. The work of Tai et al. Preoperative BMI was the lowest among all presented studies at This corresponded with a The work of Lakdawala et al. Volume and pressure assessments performed by Yehoshua et al. Increased gastric pressure leads to a relative hypotension of the LES and may lead to increased reflux. Neofundus formation refers to the dilation of the sleeve to an extent where normal physiological compliance is exceeded.

The dilation of the neofundus effectively creates a mid-stomach stenosis in SG patients. This may lead to gastric stasis and increased acid production.
