Sleeve gastrectomy as a bridge to maternity in a patient with obesity, infertility and tetraplegia. A case report.

Traumatic spinal cord injury (SCI) is a major cause of severe and permanent disability in young adults. Overweight and obesity are commonly observed among patients affected with SCI, with reports of a prevalence of over 60 and 30% respectively. Case report: A 34 year-old woman suffering from tetraplegia after sustaining a traumatic injury to C5-C6 at age 23 as a result of a motor vehicle accident was presented to our hospital's multidisciplinary bariatric team due to class II obesity. At the time of presentation to the team, eleven years after the accident, her BMI was calculated to be 39 Kg/m2 (weight 97 kg, height 1.57 meters). She was diagnosed with infertility while seeking pregnancy, and referred to our bariatric unit for weight loss. In addition, she had overcome the physical limitations of her injury, had a regular job and was engaged in regular physical activities such as swimming. In May 2017, she underwent laparoscopic sleeve gastrectomy (LSG) without complications and was discharged on postoperative day 2. 17 months following LSG, with a normal BMI, she became naturally pregnant. She had emergency cesarean at 35 weeks due to pneumonia but both patient and child recovered without sequelae. Currently, 4 years after surgery she maintains 37.11% total weight loss (weight 61 kg). She reports having a better quality of life with fewer medical intercurrencies. Conclusions: Patients with SCI and obesity, particularly women seeking to conceive, may be benefited by being referred to bariatric teams for assessment and treatment to improve results associated with sustained weight reduction.

ESTUDIO METAGENÓMICO DE LA MICROBIOTA INTESTINAL EN PACIENTES CON OBESIDAD MÓRBIDA SOMETIDOS A CIRUGÍA BARIÁTRICA / METAGENOMIC STUDY OF THE INTESTINAL MICROBIOTA IN PATIENTS WITH MORBID OBESITY UNDERGOING BARIATRIC SURGERY

Introducción: La cirugía bariátrica (CB) es un tratamiento quirúrgico de la obesidad, cuyo objetivo es lograr el descenso de peso, de masa grasa y alcanzar un impacto metabólico a largo plazo. Se ha observado que ciertos pacientes no responden tan efectivamente a la cirugía, teniendo un descenso de peso inefectivo o recuperando peso tardíamente, y los mecanismos por lo que esto ocurre aún no están bien caracterizados. La microbiota intestinal tiene un rol esencial en varios de los procesos metabólicos asociados a la obesidad. El objetivo de este estudio fue caracterizar el metagenoma intestinal de pacientes candidatos para CB y otros que fueron operados, así como también evaluar las diferencias entre aquellos pacientes que tuvieron un resultado exitoso de la CB y los que no. Material y método: Se extrajo el ADN de 200 mg de heces de pacientes que cumplen criterios de CB, divididos en 3 grupos, basal (preoperatorio), 12 meses y más de 24 meses postoperatorios, con el fin de estudiar y comparar el perfil taxonómico de las comunidades bacterianas de la microbiota intestinal. Resultados: Mientras que la riqueza específica de los grupos de estudio no presentó diferencias significativas, la diversidad beta, que considera las abundancias relativas de los miembros de las comunidades bacterianas estudiadas, evidenció una composición global significativamente diferente entre los grupos de estudio. Sin embargo, nuestro análisis no identificó taxones específicos que pudieran dar explicación a la distinta evolución postoperatoria de los pacientes. Discusión: En la estructura de las comunidades microbianas, se observaron diferencias numéricas entre los grupos en cuanto a la riqueza y abundancia de taxones así como la comparación cuanti y cualitativa. Esta última presentó significativa disimilitud. Los resultados muestran que la principal diferencia entre los grupos de estudio se basó en la abundancia relativa de los gérmenes, cuyo estudio integral podría revelar patrones más consistentes y significativos vinculados a los mecanismos de respuesta terapéutica en sujetos sometidos a CB

Introduction: Bariatric surgery (BS) is a surgical treatment of obesity, which aims to achieve weight loss, fat mass loss and achieve a long-term metabolic impact. It has been observed that certain patients do not respond as effectively to surgery, having ineffective weight loss or regaining weight late, and the mechanisms by which this occurs are not yet well characterized. The intestinal microbiota plays an essential role in several of the metabolic processes associated with obesity. The objective of our study was to characterize the intestinal metagenome of candidate patients for CB and others who underwent surgery, as well as evaluate the differences between those patients who had a successful outcome from CB and those who did not. Material and method: DNA was extracted from 200 mg of feces from patients who met the criteria for surgical indication divided into 3 groups, baseline (preoperative), 12 months and more than 24 months postoperatively, in order to analyze and compare the taxonomic profile of the bacterial communities of the intestinal microbiota. Results: While the specific richness of the study groups did not present significant differences, beta diversity, which considers the relative abundances of the members of the bacterial communities studied, showed a significantly different global composition between the study groups. Nevertheless, our study did not identify specific taxa that could explain the different postoperative evolution of the patients. Discussion: In the structure of the microbial communities, numerical differences were observed between the groups in terms of the richness and abundance of taxa as well as the quantitative and qualitative comparison. The latter evidenced significant dissimilarity. The results show that the main difference between the study groups was based on the relative abundance of the germs, whose comprehensive study could reveal more consistent and significant patterns linked to the therapeutic response mechanisms in subjects subjected to CB. Bariatric surgery (BS) is a surgical treatment of obesity, whose objective is to achieve weight loss, fat mass and achieve a longterm metabolic impact. However, it has been observed that certain patients do not respond as effectively to surgery, having ineffective weight loss or late weight regain, and the mechanisms by which this occurs are not yet well characterized. The intestinal microbiota plays an essential role in several of the metabolic processes associated with obesity. The aim of this study was to characterize the intestinal metagenome of patients who will and who underwent BS, as well as to assess the differences between those patients who had a successful BS outcome and those who did not. Our results did not identify specific taxa that could explain the different evolution of the patients. While the specific richness of the study groups did not present significant differences, the beta diversity, which considers the relative abundances of the members of the studied bacterial communities, showed a significantly different global composition between the study groups

Primary lymphoma of the entire esophagus diagnosed by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA).

Primary esophageal lymphoma is extremely rare, with fewer than 30 cases reported in the literature. Presentation is nonspecific with multiple radiological and endoscopic appearances, posing its diagnosis a challenge. We report a case of a primary esophageal lymphoma diagnosed by endoscopic ultrasound-fine needle aspiration in a 68-year-old woman referred to our hospital for evaluation of a submucosal tumor spreading all over the esophageal wall. We describe its clinical and imaging features and stand out the importance of having a specific preoperatory diagnosis in order to avoid a major surgery.

Laparoscopic Conversion of Gastric Plication to Roux-en-Y Gastric Bypass.

PURPOSE: Laparoscopic gastric plication (LGP) is a relative new bariatric procedure with a high revision rate, mostly to sleeve gastrectomy. There are few reported cases of conversion to Roux-en-Y gastric bypass (RYGB). The purpose of this video was to show the feasibility and safety, as well as the main technical aspects, of a laparoscopic conversion of gastric plication to RYGB. MATERIALS AND METHODS: A 40-year-old morbidly obese woman with a previous LGP, consulted for insufficient weight loss, weight regain, and gastroesophageal reflux disease (GERD) symptoms, and was converted to RYGB. RESULTS: Surgical technique included lysis of adhesions between the stomach and the greater omentum, take down of the plication, partial gastrectomy of the devascularized fundus and body and conversion to RYGB. At 30 months, she has achieved a total weight loss (TWL) of 42.43% with no GERD symptoms recurrence. CONCLUSION: Conversion to RYGB is a safe and effective option to treat weight recidivism and GERD after LGP.

Laparoscopic transcystic common bile duct exploration as treatment for choledocholithiasis after Roux-en-Y gastric bypass.

BACKGROUND: Treatment of choledocholithiasis after Roux-en-Y gastric bypass (RYGB) is a therapeutic challenge given the altered anatomy. To overcome this technical difficulty, different modified endoscopic approaches have been described but significant morbidity accompanies these procedures. The aim of the present study is to report our experience with laparoscopic transcystic common bile duct exploration (LTCBDE) as treatment of choledocholithiasis after RYGB. METHODS: This is a retrospective cohort study of 854 consecutive patients with RYGB at a single institution between January 2007 and December 2019. Our study population focused on patients who developed biliary events after RYGB. Demographic data and perioperative parameters were compared between patients who underwent laparoscopic cholecystectomy (LC) after RYGB with (defined as Group A) and without (defined as Group B) LTCBDE. RESULTS: Fifty-seven (8.93%) patients developed a biliary event after RYGB that led to LC. Of those, 11 (19.2%) presented choledocholithiasis during intraoperative cholangiogram and were simultaneously treated with LTCBDE (Group A). Choledocholithiasis was unsuspected in the preoperative setting in 7 (63.6%) of the 11 patients. The procedure was successful in 90.9% (n = 10). Comparing Group A and B, no statistically significant differences were found regarding age, gender, length of hospital stay, and morbidity (p > 0.05). Mean operative time of Group A was 113.1 min, adding, on average, 35 min to LC (113.1 min vs 77.9 min, p = 0.004). CONCLUSIONS: LTCBDE offers an effective approach for common bile duct stones in patients who underwent RYGB. This procedure did not add significant length of hospital stay nor morbidity to laparoscopic cholecystectomy.

Laparoscopic Removal of Eroded Non-Adjustable Gastric Band and Conversion to Roux-en-Y Gastric Bypass.

This video shows the case of a 64-year-old morbidly obese woman, with a non-adjustable gastric band, who consulted for weight regain and gastroesophageal reflux disease (GERD) symptoms and was converted to Roux-en-Y gastric bypass (RYGB). The operative technique included extensive lysis of adhesions, complete band dissection, partial gastrectomy of the fundus and body due to band erosion and conversion to RYGB.

Pneumo-PET-CT: Initial Results of This Novel Technique on the Evaluation of Esophageal and Gastric Tumors with Anatomic-Surgical Correlation.

We present the initial results of a novel hybrid scanning-based technique that combines pneumo-computed tomography (PNCT) with positron emission tomography (PET) using 2-(fluorine-18) fluoro-2-deoxy-D-glucose (FDG). We denominate it pneumo-PET-CT. The focus of our discussion will be on the description of the pneumo-PET-CT technique and the interpretation criteria with emphasis on its benefits and applications in the presurgical and postneoadjuvant therapy evaluation of esophageal, esophagogastric junction (EGJ), and gastric tumors.

Laparoscopic revisional surgery for an unusual complication of Roux-en-Y gastric bypass.

With the worldwide epidemic of obesity, there has been an increase in the numbers of primary and revisional procedures of bariatric surgery such as the Roux-en-Y gastric bypass (RYGBP). Nevertheless, this type of surgery is not exempt from complications. An excessive length of non-functional Roux limb proximal to the jejunojejunostomy can cause abnormal upper gastrointestinal symptoms after laparoscopic RYGBP. We present the case of a female patient who presented these unspecific abdominal symptoms after laparoscopic RYGBP who underwent laparoscopic resection in order to reduce the length of the dilated blind loop responsible for the symptoms.
