RESUMEN
BACKGROUND: Whether the benefits of the robotic platform in bariatric surgery translate into superior surgical outcomes remains unclear. The aim of this retrospective study was to establish the 'best possible' outcomes for robotic bariatric surgery and compare them with the established laparoscopic benchmarks. METHODS: Benchmark cut-offs were established for consecutive primary robotic bariatric surgery patients of 17 centres across four continents (13 expert centres and 4 learning phase centres) using the 75th percentile of the median outcome values until 90 days after surgery. The benchmark patients had no previous laparotomy, diabetes, sleep apnoea, cardiopathy, renal insufficiency, inflammatory bowel disease, immunosuppression, history of thromboembolic events, BMI greater than 50â kg/m2, or age greater than 65 years. RESULTS: A total of 9097 patients were included, who were mainly female (75.5%) and who had a mean(s.d.) age of 44.7(11.5) years and a mean(s.d.) baseline BMI of 44.6(7.7) kg/m2. In expert centres, 13.74% of the 3020 patients who underwent primary robotic Roux-en-Y gastric bypass and 5.9% of the 4078 patients who underwent primary robotic sleeve gastrectomy presented with greater than or equal to one complication within 90 postoperative days. No patient died and 1.1% of patients had adverse events related to the robotic platform. When compared with laparoscopic benchmarks, robotic Roux-en-Y gastric bypass had lower benchmark cut-offs for hospital stay, postoperative bleeding, and marginal ulceration, but the duration of the operation was 42â min longer. For most surgical outcomes, robotic sleeve gastrectomy outperformed laparoscopic sleeve gastrectomy with a comparable duration of the operation. In robotic learning phase centres, outcomes were within the established benchmarks only for low-risk robotic Roux-en-Y gastric bypass. CONCLUSION: The newly established benchmarks suggest that robotic bariatric surgery may enhance surgical safety compared with laparoscopic bariatric surgery; however, the duration of the operation for robotic Roux-en-Y gastric bypass is longer.

Background: Although medical treatment is the best approach for treating gastroesophageal reflux disease (GERD), surgery has a significant role to play not only in cases of failure of medical treatment but also as in a long-term approach, specifically in young patient. On the other hand, alarming reports have been published concerning the outcomes and usefulness of antireflux surgery (ARS). The aim of this study was to evaluate medium and long-term functional outcomes following ARS performed in our institution over a 10 year period.Methods: This was a retrospective review of patients in our department who underwent primary or redo laparoscopic fundoplication between 2005 and 2015. Evaluation of the outcomes was made using a validated questionnaire specifically dedicated to GERD (the Gastroesophageal Reflux Disease - Health-Related Quality of Life (GERD-HRQL) questionnaire) and by investigation about the continued use of proton-pump inhibitors (PPIs). Exclusion criteria were patients treated for GERD with Roux-en-Y gastric bypass, emergency reduction of hiatal hernia, patients missing from follow-up and patients deceased from unrelated causes.Results: 296 patients out of 309 met the inclusion criteria. Primary procedures included 214 Nissen, 35 Toupet, and 23 Collis gastroplasty; there were additionally 62 redo operations. Neither postoperative mortality nor conversion was observed. The mean follow-up was 8 years post-surgery, and contact was made with 96% of the original group. 85% of the patients had stopped PPI use since their operation (86% after Nissen, 73% after Toupet, 94% after Collis and 82% after redos). 90% of the patients had good to excellent functional results as reported by their GERD-HRQL score, and independent of the type of previous procedure. 31 patients were dissatisfied due to dysphagia in 7 and GERD recurrence in 24. Again 75% were extremely satisfied and 15% satisfied. Our own incidence of redo procedures was 11% but the functional result and satisfaction index were comparable between redo and primary procedures. The addition of Collis gastroplasty in cases of real short oesophagus did not alter the final result.Conclusions: Laparoscopic ARS presents a superior alternative to lifetime medication use and can provide long-term control of GERD symptoms in the majority of patients if it is performed skillfully and in carefully evaluated patients. Based on the present study, we believed that significant improvement in GERD health-related quality of life can be attained following both primary and reoperative ARS.

INTRODUCTION: Revisional bariatric surgery (RBS) for insufficient weight loss/weight regain or metabolic relapse is increasing worldwide. There is currently no large multinational, prospective data on 30-day morbidity and mortality of RBS. In this study, we aimed to evaluate the 30-day morbidity and mortality of RBS at participating centres. METHODS: An international steering group was formed to oversee the study. The steering group members invited bariatric surgeons worldwide to participate in this study. Ethical approval was obtained at the lead centre. Data were collected prospectively on all consecutive RBS patients operated between 15th May 2021 to 31st December 2021. Revisions for complications were excluded. RESULTS: A total of 65 global centres submitted data on 750 patients. Sleeve gastrectomy (n = 369, 49.2 %) was the most common primary surgery for which revision was performed. Revisional procedures performed included Roux-en-Y gastric bypass (RYGB) in 41.1 % (n = 308) patients, One anastomosis gastric bypass (OAGB) in 19.3 % (n = 145), Sleeve Gastrectomy (SG) in 16.7 % (n = 125) and other procedures in 22.9 % (n = 172) patients. Indications for revision included weight regain in 615(81.8 %) patients, inadequate weight loss in 127(16.9 %), inadequate diabetes control in 47(6.3 %) and diabetes relapse in 27(3.6 %). 30-day complications were seen in 80(10.7 %) patients. Forty-nine (6.5 %) complications were Clavien Dindo grade 3 or higher. Two patients (0.3 %) died within 30 days of RBS. CONCLUSION: RBS for insufficient weight loss/weight regain or metabolic relapse is associated with 10.7 % morbidity and 0.3 % mortality. Sleeve gastrectomy is the most common primary procedure to undergo revisional bariatric surgery, while Roux-en-Y gastric bypass is the most commonly performed revision.

BACKGROUND: In this prospective non randomized observational cohort study we have evaluated the influence of age on outcome of laparoscopic total fundoplication for GERD. METHODS: Six hundred and twenty consecutive patients underwent total laparoscopic fundoplication for GERD. Five hundred and twenty-four patients were younger than 65 years (YG), and 96 patients were 65 years or older (EG). The following parameters were considered in the preoperative and postoperative evaluation: presence, duration, and severity of GERD symptoms, presence of a hiatal hernia, manometric and 24 hour pH-monitoring data, duration of operation, incidence of complications and length of hospital stay. RESULTS: Elderly patients more often had atypical symptoms of GERD and at manometric evaluation had a higher rate of impaired esophageal peristalsis in comparison with younger patients. The duration of the operation was similar between the two groups. The incidence of intraoperative and postoperative complications was low and the difference was not statistically significant between the two groups. An excellent outcome was observed in 93.0% of young patients and in 88.9% of elderly patients (p = NS). CONCLUSIONS: Laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients, warranting low morbidity and mortality rates and a significant improvement of symptoms comparable to younger patients.

BACKGROUND: Littoral cell angioma (LCA) is a rare vascular primary tumor of the spleen with no more than 440 cases described so far. Although often seen as benign, it is described to have malignant potential and to be associated with other immunologic disorders or malignancies. CASE PRESENTATION: We present the case of LCA in a 75-year old man with a concomitant non-Hodgkin lymphoma and medical history of malign melanoma. The tumor was discovered incidentally after splenectomy for splenomegaly and refractory thrombocytopenia. The post-operative period was uneventful. CONCLUSION: Our case is the first to report an association of LCA with both lymphoma and melanoma thus far. It emphasizes the need for a thorough total body examination for synchronous diseases and close follow-up to reveal associated malignancies or immunologic disorders. Further research is required to identify etiologic and pathogenetic mechanisms behind this tumor and a common basis between the three diseases. KEY WORDS: Littoral Cell Angioma, Neoplasm, Splenectomy, Solid Spleen Tumor.

BACKGROUND: Pancreaticoduodenectomy (PD) is one of the most demanding interventions for digestive surgeons. R0 resection is a key point for the overall survival and disease-free survival. Total mesopancreas excision (TMpE) has been described by laparotomy but laparoscopy did not provide good results probably because of the technical difficulties of the approach. We propose a standardised total robotic approach. METHODS: In this step-by-step technical description, we propose as example, a case of a 53-year-old man with a pancreatic head adenocarcinoma with doubts about the invasion of the mesopancreas surrounding superior mesenteric artery. The mesopancreas hanging manoeuver allows us to perform a TMpE. RESULTS: The surgery performed was a robotic artery first pancreaticoduodenectomy with TMpE. The pathological result was pancreatic ductal adenocarcinoma pT2, N1 (1/23), M0, V0, L0, Pn0, R0. CONCLUSIONS: Robotic approach is safe, effective and reproductible. Through a standardised technique, it may overcome some of the technical difficulties of laparoscopic PD.

The true short esophagus is an entity of controversy among surgeons. Studies have been published about its diagnosis and laparoscopic treatment, without existing to date, publication of the treatment with robotic approach. We present, as a case report, our experience in robotic surgery for hiatal hernia with true short esophagus treated with Collis gastroplasty and Toupet fundoplication. Robotic surgery on the true short esophagus can facilitate mediastinal dissection and allow a more accurate suture technique. Studies are needed to compare the long-term results of this surgical technique between the conventional laparoscopic approach and the robotic approach.

INTRODUCTION: Obesity is a strong independent risk factor of gastroesophageal reflux disease (GERD) symptoms and hiatal hernia development. Pure restrictive bariatric surgery should not be indicated in case of hiatal hernia and GERD. However it is unclear what is the real incidence of disruption of esophagogastric junction (EGJ) in patients candidate to bariatric surgery. Actually, high resolution manometry (HRM) can provide accurate information about EGJ morphology. Aim of this study was to describe the EGJ morphology determined by HRM in obese patients candidate to bariatric surgery and to verify if different EGJ morphologies are associated to GERD-related symptoms presence. METHODS: All patients underwent a standardized questionnaire for symptom presence and severity, upper endoscopy, high resolution manometry (HRM). EGJ was classified as: Type I, no separation between the lower esophageal sphincter (LES) and crural diaphragm (CD); Type II, minimal separation (>1 and < 2 cm); Type III, >2 cm separation. RESULTS: One hundred thirty-eight obese (BMI>35) subjects were studied. Ninety-eight obese patients referred at least one GERD-related symptom, whereas 40 subjects were symptom-free. According to HRM features, EGJ Type I morphology was documented in 51 (36.9%) patients, Type II in 48 (34.8%) and Type III in 39 (28.3%). EGJ Type III subjects were more frequently associated to Symptoms than EGJ Type I (38/39, 97.4%, vs. 21/59, 41.1% p < 0.001). CONCLUSIONS: Obese subjects candidate to bariatric surgery have a high risk of disruption of EGJ morphology. In particular, obese patients with hiatal hernia often refer pre-operative presence of GERD symptoms. Testing obese patients with HRM before undergoing bariatric surgery, especially for restrictive procedures, can be useful for assessing presence of hiatal hernia.

AIM: Laparoscopic Nissen fundoplication represents the gold standard in GERD therapy, although, a frequent failure of this primary repair is represented by the breakdown of the hiatoplasty. Aim of our work is to evaluate if ultrastructural alterations of the diaphragmatic pillars in patients with hiatal hernia, can explain the physiopathology of hernia recurrence. MATERIAL OF STUDY: The patients were divided into two groups: group A comprised 51 patients affected by hiatal hernia and group B (control) included 30 patients not affected by hiatal hernia.. Each patient underwent four biopsies, two from the phrenoesophageal membrane and two from the diaphragmatic pillars during laparoscopic procedures. Three hundred and twenty-four specimens, 204 from the group A and 120 from the group B, were processed and analyzed by transmission electron microscopy. RESULTS: No alterations were found in the phrenoesophageal membrane in both groups; samples from the diaphragmatic pillars showed no alteration in the group without hiatal hernia (group B). Instead, 90,2% of the muscular samples from the crura of group A patients presented ultrastructural alterations: in almost 75% of the cases the lesions were considered severe with extended disruption-degeneration of the muscle architecture. DISCUSSION: Patients with hiatal hernia have ultrastructural abnormalities of the muscular tissue of the diaphragmatic pillars that are absent in patients with normal gastroesophageal junction. CONCLUSIONS: The outcome of GERD surgery could depend not only on a correct technique but also on the underlying status of the diaphragmatic crura.

INTRODUCTION: Among the surgical procedures for treatment of morbid obesity, laparoscopic sleeve gastrectomy has known widespread diffusion in the last years, although it is not free from significant morbidity rates. Aim of this work is to evaluate the incidence of Helicobacter pylori (HP) infection on the postoperative outcome of patients undergoing laparoscopic sleeve gastrectomy. METHODS: Between January 2008 and December 2013, 184 patients (65 males, 119 females), mean age 35.8 ± 5.7 years, affected with morbid obesity, mean BMI 46.6 ± 6.7, underwent laparoscopic sleeve gastrectomy. All the specimens at the end of the operation were analysed by the same pathologist. Histological grading was based on the Sidney classification. RESULTS: Seventy-two of the patients (39.1%) were HP positive, while 112 (60.9%) were negative. No significant differences were observed between the HP+ and HP- group in terms of age, sex, weight, BMI, incidence of comorbidities and duration of follow-up. All the operations were completed via laparoscopic approach. No mortality was observed. Postoperative complications occurred in 5 patients (2.7%): three leaks (1.6%), all in the HP- group and two bleedings (1.1%), one in the HP+ and one in the HP- group. In two cases a reintervention was necessary. No significant differences were observed in the morbidity rates between the two groups. Overall mean excess weight loss at 6 months, 12 months and 24 months was respectively 47.4 ± 11.3%, 61.1 ± 12.4% and 68.4 ± 13.5%, with no significant differences between the HP+ and HP- groups. CONCLUSIONS: HP infection seems not to influence postoperative outcome of patients operated of laparoscopic sleeve gastrectomy.

Actually, achalasia can be defined as a primary esophageal motor disorder characterized by esophageal aperistalsis and abnormal post-deglutitive lower esophageal sphincter (LES) relaxation. Its incidence varies from 0.03 to 1.63 cases per 100,000 people per year and increases with age, while the prevalence is almost 10/100,000 with no difference between the sexes. Regarding etiology, the most frequent histologic alteration is represented by the loss of the myenteric nerve fibers regulating inhibitory nitrergic neurotransmission in the LES, with the presence of a lymphocytic infiltrate and collagen deposition. The cause of this loss remains unclear. Among the theories proposed, the infectious, hereditary and autoimmune etiologies have been widely investigated. The only infectious agent identified as a cause of achalasia is Trypanosoma Cruzi, responsible of Chagas' disease. Regarding hereditary component, in rare cases achalasia presents as part of a genetic syndrome such as Down syndrome, Allgrove syndrome and familial visceral neuropathy. Although, no disease-specific gene has been identified. The autoimmune hypothesis has focused on the association of specific HLA classes with achalasia. However, no consistent association has been observed across studies. Despite increasing understanding of the physiopathology of achalasia, its etiology remains largely unknown. The onset of the disease is characterized by chronic inflammation of the myenteric plexus of the esophagus secondary to an environmental insult. Probably, genetic factors are involved in the development of achalasia, although the precise molecular basis of the disease has not been identified.
