Feasibility and Safety Study of the Use of a New Robot (Maestro™) for Laparoscopic Surgery.

BACKGROUND: In laparoscopic surgery, telerobotic systems such as Da Vinci™ were developed, among other things, to give back exposure and vision control to the operating surgeon. However, new limitations such as the separation of the operating surgeon from the operating table, cost, and size were unveiled. A new device, Maestro™, appears promising in addressing these limitations. The current work evaluates the feasibility, safety, and surgeon satisfaction with the assistance provided by the Maestro System. METHODS: Non-consecutive patients who were candidates for laparoscopic digestive surgery were enrolled in a descriptive prospective, monocentric study. Case selection was solely based on the availability of the device, but not on the patient's characteristics. Surgery was performed by a leading surgeon with the help of one less experienced surgeon. Feasibility was defined by the maintenance of the initial surgical plan. Safety was assessed by the absence of serious adverse events related to the device and surgeon satisfaction was evaluated by a questionnaire following the intervention. RESULTS: All 50 procedures were completed without conversion in laparotomy and without adjustment of the surgical team. Four complications were recorded during the study; however, none related to the use of the Maestro System. In 92% of the cases, the surgeon was satisfied with the assistance provided by the Maestro System. CONCLUSIONS: In standard elective digestive procedures by laparoscopy, the use of the Maestro System is feasible and safe. It is beneficial to the surgeon and operative room organization by limiting the size of the surgical team.

Sleeve gastrectomy with duodenoileal bipartition using linear magnets: feasibility and safety at 1-year follow-up.

BACKGROUND: Single-anastomosis metabolic/bariatric surgery procedures may lessen the incidence of anastomotic complications. This study aimed to evaluate the feasibility and safety of performing side-to-side duodenoileal (DI) bipartition using magnetic compression anastomosis (MCA). In addition, preliminary efficacy, quality of life (QoL), and distribution of food through the DI bipartition were evaluated. METHODS: Patients with a body mass index (BMI) of ≥35.0 to 50.0 kg/m2 underwent side-to-side DI bipartition with the magnet anastomosis system (MS) with sleeve gastrectomy (SG). By endoscopic positioning, a distal magnet (250 cm proximal to the ileocecal valve) and a proximal magnet (first part of the duodenum) were aligned with laparoscopic assistance to inaugurate MCA. An isotopic study assessed transit through the bipartition. RESULTS: Between March 14, 2022 to June 1, 2022, 10 patients (BMI of 44.2 ± 1.3 kg/m2) underwent side-to-side MS DI. In 9 of 10 patients, an SG was performed concurrently. The median operative time was 161.0 minutes (IQR, 108.0-236.0), and the median hospital stay was 3 days (IQR, 2-40). Paired magnets were expelled at a median of 43 days (IQR, 21-87). There was no device-related serious advanced event within 1 year. All anastomoses were patent with satisfactory diameters after magnet expulsion and at 1 year. Respective BMI, BMI reduction, and total weight loss were 28.9 ± 1.8 kg/m2, 15.2 ± 1.8 kg/m2, and 34.2% ± 4.1%, respectively. Of note, 70.0% of patients reported that they were very satisfied. The isotopic study found a median of 19.0% of the meal transited through the ileal loop. CONCLUSION: Side-to-side MCA DI bipartition with SG in adults with class II to III obesity was feasible, safe, and efficient with good QoL at 1-year follow-up. Moreover, 19% of ingested food passed directly into the ileum.

The Utilisation of Digital Applications for Measuring Patient Outcomes Following Bariatric Surgery: a Systematic Review and Meta-analysis of Comparative Studies.

In the context of escalating obesity rates, bariatric surgery holds a crucial role in managing severely obese patients. With a demonstrated effectiveness in weight loss and with the advent of ambulatory surgery, bariatric surgery allows for a streamlined care pathway, ideally suited for postoperative surveillance using digital health applications. The aim of this systematic review and meta-analysis is to evaluate the effect of eHealth-delivered health services or support for adults undergoing bariatric surgery. Five studies, encompassing 2210 patients, were analysed. The intervention group showed a 10% increase in total weight reduction and a 22% reduction in excess weight loss. ED visitation rates also trended towards reduction. Despite the absence of clear statistical superiority for DHA, the findings suggest potential benefits of DHA in postoperative monitoring.

Bariatric Artery Embolization for Obese Patients. An Up-to-Date Review.

Overweight and obesity are one of public health's major problems in the world. Conservative treatment with exercise, diet and pharmacotherapy is often ineffective, especially in the long term. Bariatric surgery is the gold standard method for a sustained long-term weight loss. Recently the endovascular technique of bariatric artery embolization (BAE) has been studied as an obesity and overweight treatment, with promising results. The goal of this article is to analyze the rationale behind BAE and to provide an up-to-date analysis of its strengths and limitation in comparison with bariatric surgery as a treatment for obesity.

First human surgery using a surgical assistance robotics device for laparoscopic cholecystectomies.

BACKGROUND: Over the past 20 years, surgeons involved in soft tissue minimally invasive surgery have experienced the pros and cons of both conventional and tele-robotic laparoscopic approaches. The Maestro System, developed by Moon Surgical (Paris, France) aims to overcome the challenges inherent to both approaches thanks to a new concept that augments the surgeon's performance at the bedside during a laparoscopic procedure. METHODS: The current study aims to present the first human experience with laparoscopic cholecystectomy with the Maestro system on 10 patients. RESULTS: All ten procedures were completed successfully. No significant complications related to the use of the Maestro system werenoted. CONCLUSION: Our preliminary observations appear to support the benefits of the Maestro system in non-emergent laparoscopic cholecystectomies. It goes without saying that further research is necessary to demonstrate the safety of this approach in other procedures.

Is a giant incisional hernia a contraindication for laparoscopic cholecystectomy?

Laparoscopic cholecystectomy (LC) is one of the most commonly performed surgical procedures worldwide. A previous abdominal operation is not considered a significant risk factor for conversion to open cholecystectomy. We describe the case of an 80-year-old woman with a surgical history of a giant uncomplicated incisional midline hernia presenting at our department with choledocholithiasis and acute cholangitis. After an ERCP with extraction of common bile duct stones, a LC was planned. The first trocar was inserted in the right midclavicular line, using an open technique and a careful inspection of the abdominal cavity and the hernia sac content. An uncomplicated cholecystectomy was performed and the postoperative course was uneventful.

Side-to-side magnet anastomosis system duodeno-ileostomy with sleeve gastrectomy: early multi-center results.

INTRODUCTION: Gastrointestinal anastomoses with classical sutures and/or metal staples have resulted in significant bleeding and leak rates. This multi-site study evaluated the feasibility, safety, and preliminary effectiveness of a novel linear magnetic compression anastomosis device, the Magnet System (MS), to form a side-to-side duodeno-ileostomy (DI) diversion for weight loss and type 2 diabetes (T2D) resolution. METHODS: In patients with class II and III obesity (body mass index [BMI, kg/m2] ≥ 35.0- ≤ 50.0 with/without T2D [HbA1C > 6.5%]), two linear MS magnets were delivered endoscopically to the duodenum and ileum with laparoscopic assistance and aligned, initiating DI; sleeve gastrectomy (SG) was added. There were no bowel incisions or retained sutures/staples. Fused magnets were expelled naturally. Adverse events (AEs) were graded by Clavien-Dindo Classification (CDC). RESULTS: Between November 22, 2021 and July 18, 2022, 24 patients (83.3% female, mean ± SEM weight 121.9 ± 3.3 kg, BMI 44.4 ± 0.8) in three centers underwent magnetic DI. Magnets were expelled at a median 48.5 days. Respective mean BMI, total weight loss, and excess weight loss at 6 months (n = 24): 32.0 ± 0.8, 28.1 ± 1.0%, and 66.2 ± 3.4%; at 12 months (n = 5), 29.3 ± 1.5, 34.0 ± 1.4%, and 80.2 ± 6.6%. Group mean respective mean HbA1C and glucose levels dropped to 1.1 ± 0.4% and 24.8 ± 6.6 mg/dL (6 months); 2.0 ± 1.1% and 53.8 ± 6.3 mg/dL (12 months). There were 0 device-related AEs, 3 procedure-related serious AEs. No anastomotic bleeding, leakage, stricture, or mortality. CONCLUSION: In a multi-center study, side-to-side Magnet System duodeno-ileostomy with SG in adults with class III obesity appeared feasible, safe, and effective for weight loss and T2D resolution in the short term.

Surgical chest complications after liver transplantation.

Liver transplantation is a major abdominal operation and the intimate anatomic relation of the liver with the right hemidiaphragm predisposes the patient to various manifestations in the chest cavity. Furthermore, chronic liver disease affects pulmonary function before and after liver transplantation resulting in a considerable percentage of patients presenting with morbidity related to chest complications. This review aims to identify the potential chest complications of surgical interest during or after liver transplantation. Complications of surgical interest are defined as those conditions that necessitate an invasive procedure (such as thoracocentesis or a chest tube placement) in the chest or a surgical intervention performed by a thoracic surgeon. These complications will be classified as perioperative and postoperative; the latter will be categorized as early and late. Although thoracocentesis or a chest tube placement is usually sufficient when invasive measures are deemed necessary, in some patients, thoracic surgical interventions are warranted. A high index of suspicion is needed to recognize and treat these conditions promptly. A close collaboration between abdominal surgeons, intensive care unit physicians and thoracic surgeons is of paramount importance.
