Objective: Retrospective case-matched comparison of magnetic liver retraction to a bedrail-mounted liver retractor in bariatric surgery specifically targeting short-term postoperative outcomes, including pain and resource utilization. Background: Retraction of the liver is essential to ensure appropriate visualization of the hiatus in bariatric surgery. Externally mounted retractors require a dedicated port or an additional incision. Magnetic devices provide effective liver retraction without the need of an incision. Methods: The sample consisted of primary and revisional bariatric surgery patients, including Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and biliopancreatic diversion with duodenal switch (BPD-DS) operations. Propensity score analysis was used to match patients with magnetic retraction to patients with a bedrail-mounted retractor with a 1:2 ratio using preoperative characteristics. Baseline characteristics and postprocedure outcomes were compared using two-sample t-tests or Wilcoxon rank sum tests and chi-square or Fisher's exact test as appropriate. Results: One hundred patients met inclusion criteria for the use of magnetic liver retraction (45 RYGB, 35 SG, 20 BPD-DS) with 196 suitable matched external retractor patients identified. Patients were matched and comparable for all preoperative characteristics except for transversus abdominus plane block (27% versus 47%). Patients in the magnet cohort had significantly decreased mean 12-hour postoperative pain scores (2.9 versus 4.2, P = .004) and decreased hospital length of stay (LOS) (1.5 versus 1.9 days, P = .005) while operating room supply were higher in the magnet cohort ($4600 versus $4213, P = .0001). Conclusions: Magnetic liver retraction in bariatric surgery is associated with decreased postoperative pain scores, decreased hospital LOS, and increased operating supply costs.

The abdominal wall and musculoskeletal tendons share many anatomic, physiologic, and functional characteristics. This review aims to highlight these similar characteristics and to present a rationale why the treatment principles of successful musculoskeletal tendon reconstruction, including principles of surgical technique and physical therapy, can be used in the treatment of complex abdominal wall reconstruction or ventral hernia repair. The MEDLINE/PubMed database was used to identify published literature relevant to the purpose of this review. There are several anatomical and functional similarities between the linea alba and musculoskeletal tendons. Because of this reason, many of the surgical principles for musculoskeletal tendon repair and ventral hernia repair overlap. Distribution of tension is the main driving principle for both procedures. Suture material and configuration are chosen to maximize tension distribution among the tissue edges, as seen in the standard of care multistrand repairs for musculoskeletal tendons, as well as in the small bites for laparotomy technique described in the STITCH trial. Physical therapy is also one of the mainstays of tendon repair, but surprisingly, is not routine in ventral hernia repair. The evidence surrounding physical therapy prehabilitation and rehabilitation protocols in other disciplines is significant. This review challenges the fact that these protocols are not routinely implemented for ventral hernia repair, and presents the rationale and feasibility for the routine practice of physical therapy in ventral hernia repair.

Background Racial disparities in postoperative complications have been demonstrated in bariatric surgery, yet the relationship of race to complication severity is unknown. Study Design Adult laparoscopic primary bariatric procedures were queried from the 2015 and 2016 MBSAQIP registry. Adjusted logistic and multinomial regressions were used to examine the relationships between race and 30-day complications categorized by the Clavien-Dindo grading system. Results A total of 212,970 patients were included in the regression analyses. For Black patients, readmissions were higher (OR = 1.39, p

Endoscopy is essential in the assessment and treatment of the bariatric patient, especially in the postoperative state. Since bariatric surgery is increasing exponentially, endoscopists should be familiar with the anatomy and how to manage possible complications. New less invasive therapeutic tools will have a major impact on the prognosis of these patients. Dreaded complications such as leaks, stenosis or weight regain can be successfully assessed and treated by endoscopy. Postoperative evaluation of symptoms requires the precise search of details that can change patient's management.

Background The DiaRem score has proven to be a reliable predictor tool for diabetes remission in Roux-en-Y gastric bypass (RYGB), as well as laparoscopic adjustable gastric band (LAGB) and laparoscopic sleeve gastrectomy (LSG). To our knowledge there are no studies that analyze DiaRem in patients undergoing biliopancreatic diversion with duodenal switch (BPD/DS). Objective To test the validity of the DiaRem score as a predictor of type 2 diabetes remission at 1 year post surgery in patients who underwent LABG, LSG, RYGB, and BPD/DS, as well as to develop and test a novel model that uses DiaRem to predict type 2 diabetes remission by procedure type (LABG, LSG, RYGB, and BPD/DS). Setting University Medical Center, United States. Methods A retrospective review of institutional records identified patients who underwent primary bariatric procedures (LAGB, LSG, RYGB, and BPD/DS) between January 1, 2000 to April 10, 2017, had a diagnosis of diabetes and had complete preoperative and 1-year postoperative follow-up information. A univariable logistic regression model was fit to assess the association between DiaRem score and diabetes remission. A multivariable logistic regression model was created, including procedure type and other preoperative characteristics. The area under the receiver operating curve (AUROC) was calculated to analyze the performance of both models for the entire cohort as well as a BPD/DS only subgroup. Results A total study cohort of 602 was obtained. The majority of patients underwent RYGB (456; 75.7%), followed by LSG (84; 14.0%), BPD/DS (35; 5.8%), and LAGB (27; 4.5%). The multivariable regression model with RYGB as the reference procedure, showed that BPD/DS results in higher odds of type 2 diabetes remission at 1 year post surgery (adjusted odds ratio [OR] 3.29, 95% confidence interval [CI] 1.27, 8.51), while LSG (adjusted OR .52, 95%CI .29, .93) and LAGB resulted in lower odds (adjusted OR.23, 95% CI.09,.60). The univariable DiaRem model and the novel model were determined to be moderately strong in classifying diabetes remission in the entire cohort (AUROC: .79, 95% CI: .75, .83 and .82, 95% CI: .79, .85, respectively) as well as in the BPD/DS sub-group (AUROC: .85, 95% CI: .70, .99 and .84, 95% CI .69, .99, respectively). Conclusion Our study shows that the DiaRem score is a reliable tool to predict diabetes remission, amongst a wide variety of different procedures as well as specifically those receiving BPD/DS. Our novel model, which takes into account procedure type, not only shows that BPD/DS patients have the highest odds of diabetes remission than other procedures, but also that this model performs significantly better at predicting diabetes remission than DiaRem alone.

This study aims to determine if cosmetic outcomes play an important role for patients undergoing bariatric surgery, when considering a surgical approach. A video-animation describing open, conventional laparoscopic, and reduced incision magnetic assisted surgery was shown. The patient's perceptions of the surgical approaches were recorded using an anonymous survey. Fifty-one patients completed the survey. The median age was 45 (IQR: 36-51), and 38 (74.5%) were women. Cosmesis was found to be an important factor (77%) for selecting a surgical approach. Ninety percent of the patients believe that reduced incision magnet-assisted surgery provides superior cosmesis. Cosmetic results may play a determinant role when choosing a surgical approach.

Background and study aims Sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure in the world. Leaks are the most feared complications after this procedure. Endoscopic septotomy has been described as a resolution technique that could be useful in the setting of late and chronic leaks. We present our experience in the management of gastric leaks with this advanced endoscopic technique. Patients and methods Retrospective review of patients who have been admitted to our hospital from January 2016 to December 2018. Results Five patients were found. All had their index surgery in outside hospitals. The average age was 51 years (range 40 – 69), and four patients were female. Mean time from LSG to leak presentation was 15 days (range 7 – 25). Mean time from leak presentation to septotomy procedure was 61 days (range 21 – 110). All patients were treated with sleeve dilatation before septotomy using endoscopic achalasia balloons. Mean procedure time was 79 minutes (range 55 – 125). Success was achieved in 80 % of patients, and no complications related to the procedure were identified. One patient underwent total gastrectomy for definitive management. Mean follow-up time was 14.25 months (range 6 – 26), and the average time for fistula closure was 60.25 days. Conclusion Endoscopic septotomy is safe and effective for management of chronic leaks after LSG. Associated non-selective dilatation may be a crucial step to allow distal patency and axis rectification for appropriate leak closure.

Background Vocal Cord Dysfunction (VCD) is a respiratory condition in which vocal cords restrict airflow by closing during inspiration. Symptoms include shortness of breath, coughing, chest tightness and wheezing. These symptoms are commonly reduced with breathing exercises to relax the chest and throat. VCD is often misdiagnosed as asthma and treated as such. Studies have shown that steroids used to treat asthma are not beneficial in the treatment of VCD, and are therefore unnecessary. Recent studies suggest that Botox injections to relax the thyroarythenoid muscles surrounding vocal cords resulting in an improvement in the patient's airflow. Methods We followed a 56-year-old female patient over the course of a year who had a history of upper espiratory infections, sinusitis, allergic rhinitis and asthma reporting an increase in the severity of respiratory symptoms even though successfully undergoing immunotherapy treatment and following a regimen of asthma medication. Her symptoms included shortness of breath, wheezing and trouble sleeping. Results Pulmonary function testing done elsewhere revealed that the patient had a reduced lung capacity. After a consult with a speech pathologist, VCD and Spastic Dysphonia (SD) were diagnosed. The symptoms where initially treated with speech therapy. Four months later the patient noted a slight improvement in her symptoms, but also attributed this to the fact that she had developed behavioral ways to cope with symptoms. The possibility of Botox injections was mentioned and the patient agreed to follow with this treatment. Two 2.5 unit injections of Botox were administered in the thyroarythenoid muscles via an EMG guided needle, without any complications. The results from the procedure were very favorable. All her symptoms improved significantly. Lung function tests appeared normal, and she was able to reduce the use of most asthma control medications. She received another dose of Botox injections 6 months following the first, and continues to do very well. Conclusions Botox injections in the thyroarythenoid muscles are a successful treatment option for VCD patients with dysphonia. With this treatment patients are able to minimize respiratory symptoms and inhaled steroid use. A larger, randomized study with patients diagnosed with VCD alone should be considered.
