Bariatric Metabolic Surgery Might be More of a Benefit than a Risk During a Pandemic Outbreak.

This report aimed to analyze the outcomes of patients with obesity who were on a bariatric program during the SARS-Cov-2 pandemic outbreak and compare those who received surgery with the ones who were not operated on. This was a retrospective study between 2020 and 2021. Patients were divided into two groups: those who underwent surgery (O) and those who were not operated (NO).

Sleeve Gastrectomy Reduces Oxidative Stress and Reverses Mitochondrial Dysfunction Associated with Metabolic Syndrome.

Introduction: Previous studies have detected mitochondrial alterations in tissues of individuals with obesity and type 2 diabetes mellitus (T2DM). Metabolic surgery could be an effective treatment to improve mitochondrial morphology and reduce oxidative stress (OS).

Methods: An experimental study was carried out using 48 male Wistar rats, divided into 6 groups (n = 8): control (C), induced Metabolic Syndrome (MS); intervention with sleeve gastrectomy (SG), MS + SG with 6 weeks postoperatively (MS + SG6), MS + SG with 12 weeks postoperatively (MS + SG12), and MS + SG with 24 weeks postoperatively (MS + SG24).

Development and Implementation of an Enhanced Recovery Protocol for Bariatric Patients in a Third World Environment.

An applicable and reproducible enhanced recovery protocol was developed and implemented to improve our outcomes in a third-world environment. We compared the results obtained prospectively. The group treated before the application of the enhanced recovery protocol was called usual care (UC) and included all bariatric surgeries operated on between 2014 and 2017.

Pregnancy After Sleeve Gastrectomy: Time Matters?

Purpose: Obesity has an especial implication for women of childbearing age because of a higher risk of adverse outcomes during pregnancy and labor. This report aimed to analyze complications of pregnancy after sleeve gastrectomy (SG) concerning the time after surgery.

Methods: A retrospective descriptive-analytical study was conducted including women of childbearing age who underwent sleeve gastrectomy (SG) from 2006 to 2017.

Impact of Gastric Bypass on Erosive Esophagitis and Barret's Esophagus.

Background: The association between gastroesophageal reflux disease (GERD) and obesity is clearly defined. The incidence of erosive esophagitis (EE) and Barrett's esophagus (BE) are as high as 26 and 6%, respectively. Gastric bypass (GBP) is considered the gold standard for obese patients with GERD.

Esophagitis evolution after sleeve gastrectomy or gastric bypass in consecutive cases.

Background: Erosive esophagitis (EE) is related to esophageal mucosal damage caused by GERD and is implicated in the development of Barret´s esophagus and adenocarcinoma, which incidence is rising in association with obesity. It is known that the correlation between symptoms and endoscopic findings is relatively poor, with a predictive value of only 40%. The objective of this study is to report the incidence of EE 1 year after sleeve gastrectomy (SG) and gastric bypass (GBP) in consecutive patients in order to obtain an objective parameter of the impact of the two most popular bariatric procedures on esophageal mucosa.

Risk factors for surgical site infection in colon surgery in our population.

Background: Surgical site infection (SSI) is the most common nosocomial infection in surgical patients with an incidence that varies between 5-30%.

Objective: Identify the risk factors for SSI in colonic surgery in our population. The secondary aims are to determine the incidence and type of SSI, as well as the incidence of an anastomotic leakage (AL).

Obese Patients with Type 2 Diabetes: Outcomes After Laparoscopic Sleeve Gastrectomy.

Bariatric surgery is superior to medical treatment for type 2 diabetes mellitus (T2DM) control in obese patients. Reports in the literature have been mainly based on Roux-en-Y gastric bypass (RYGB) or adjustable gastric band. The aim of this study was to analyze mid- and long-term metabolic results after laparoscopic sleeve gastrectomy (LSG).

Gastroesophageal reflux disease and morbid obesity: evaluation and treatment.

Gastroesophageal reflux disease (GERD) is markedly increased among the obese population being recognized as one of the many obesity-related comorbidities. This concept should raise awareness, making physicians investigate more profoundly about this disease in this kind of patients. Currently, bariatric surgery is considered the gold standard treatment for morbid obesity.

Impact on Dyslipidemia After Laparoscopic Sleeve Gastrectomy.

Background: Improvement of dyslipidemia is an important benefit of bariatric surgery. The benefits of laparoscopic sleeve gastrectomy (LSG) among dyslipidemia are still a matter of debate.

Methods: We conducted a retrospective descriptive study between 2010 and 2013.

Long-Term Relationship Between Tobacco Use and Weight Loss after Sleeve Gastrectomy.

Background: Smoking cessation had been typically associated with weight gain. We have reported that there is no relationship between tobacco use and weight loss after bariatric surgery in the short term. The objective of this study was to establish the relationship between weight loss and the smoking habit in patients undergoing bariatric surgery and to analyze weight loss on severe smokers and on those patients who stopped smoking during the long-term postoperative period.

Sleeve Gastrectomy after Renal Transplantation.

Background: Obesity induces or accelerates diabetes (DBT), hypertension (HT), and dyslipidemia (DSL), which are the main causes of renal failure. Obesity exacerbates in patients after renal transplantation (RT), and it has been associated with increased mortality rate, postoperative complications, and graft loss. We hypothesize that bariatric surgery might have a positive effect on obese patients with history of previous RT.

Laparoscopic Sleeve Gastrectomy: Endoscopic Findings and Gastroesophageal Reflux Symptoms at 18-Month Follow-Up.

Introduction: Laparoscopic sleeve gastrectomy (LSG) has shown excellent results in terms of weight loss and resolution of comorbidities. Despite that, the effect of LSG on gastroesophageal reflux disease (GERD) is still a controversial topic. Our objective was to evaluate the presence of gastroesophageal reflux symptoms, erosive esophagitis (EE), and hiatal hernia (HH) in obese patients undergoing LSG.

[Laparoscopic atypical gastrectomy in the treatment of gastric GIST. Short-term and medium-term outcomes].

Gastrointestinal stromal tumors are the most common mesenchymal neoplasms of the gastrointestinal tract. Recently, many studies have addressed the laparoscopic management of these tumors. The aim of this study was to evaluate the safety and efficacy of laparoscopic atypical gastrectomy in the resolution of these neoplasms.

Iatrogenic injury of the intrathoracic oesophagus with bougie during sleeve gastrectomy.

One of the most popular procedures amongst obesity surgery is the sleeve gastrectomy. There is international consensus regarding the usage of bougie for sleeve gastrectomy calibration. Nevertheless, there is a dissociation between the number of oesophageal perforations reported for any other oesophageal/gastric operation that requires bougie (e.

Incidental Finding of Gastrointestinal Stromal Tumors during Laparoscopic Sleeve Gastrectomy in Obese Patients.

Introduction: The frequency of incidental pathology found during laparoscopic bariatric surgery has been estimated to be 2%. Gastrointestinal stromal tumors (GISTs) are infrequent lesions and account for less than 1% of all digestive tract tumors. The reported incidence of this type of tumors during bariatric surgery is around 0.

Laparoscopic Repair of Giant Bochdalek Hernia in Adults.

Introduction: Bochdalek hernia is a congenital diaphragmatic defect that results from improper fusion of the septum transversum and the pleuroperitoneal folds. It rarely persists asymptomatic until adulthood. The reported incidence is as low as 0.

Sweet Eating Habit: Does This Affect the Results After Sleeve Gastrectomy?

Background: It is commonly believed that eating habits, specially the sweet eating habit, can predict results after bariatric surgery; for this reason, it is considered one of the selection criteria when deciding the surgical technique. However, there is not enough evidence of its impact on the results after sleeve gastrectomy (SG).

Objective: To evaluate the relationship between the sweet eating habit and weight loss after SG.

Relationship Between Tobacco Use and Weight Loss After Bariatric Surgery.

Background: Smoking cessation had been typically associated with weight gain. So far, there are no reports documenting the relationship between weight loss after bariatric surgery and smoking habit. The objective of the study was to establish the relationship between weight loss and smoking habit in patients undergoing bariatric surgery and to analyze weight loss on severe smokers and on those patients who stopped smoking during the postoperative period.

Esophageal metalic stent migration. Case report of a dislodged stent retrieval.

Background: Metallic stent placing is the first choice in the treatment of malign or benign strictures of the esophagus. Stent migration is a well-known complication of this procedure. We report a case of stent migration in which surgical laparoscopic intervention was used to retrieve it.

[Celiac trunk compression syndrome by the median arcuate ligament. Laparoscopic approach].

Median arcuate ligament syndrome (MALS), or celiac trunk compression syndrome, is caused by extrinsic compression of median arcuate ligament, prominent fibrous bands and periaortic nodal tissue. In many cases is asymptomatic, but it may manifests with symptoms such as postprandial abdominal pain or during exercise, nauseas, vomiting and weight loss. Trough less invasive diagnostic techniques, such as doppler ultrasound for screening and preoperative angiotomograhpy, it is possible to obtain good results, comparable to those with arteriography.

[Morgagni's hernia: Report of a case treated by videolaparoscopy].

Morgagni's hernia is a rare congenital disorder, usually asymptomatic, but may cause respiratory or gastrointestinal symptoms. We reviewed the clinical findings of a patient with a Morgagni's hernia, diagnosed and treated in our department. The Morgagni's hernia caused various symptoms in our patient and surgery was performed via laparoscopy.

[Omental hernia through esophageal hiatus simulates mediastinal lipomatous tumor].

Omental hernia through the esophageal hiatus is extemely infrequent. Paraesophageal hiatal hernia with omentum in the herniary sac mimics a mediastinal lipomatous tumor and differential diagnosis should be made. This diagnosis requires experience and knowledge of the differences between these two pathologies.
