Abstract Introduction Bariatric surgery is recognized as the most effective long-term treatment for clinically severe obesity, leading to sustained weight loss. Among common bariatric procedures, laparoscopic Roux-en-Y gastric bypass (RYGB) frequently performed and known its significant loss results ability reduce obesity-related comorbidities in many patients. However, 10% 40% of patients may experience insufficient (IWL) or regain (WR), along with persistence recurrence after 5 7 years,...
Abstract Background Roux-en-Y gastric bypass (RYGB) is the second most frequent bariatric procedure worldwide. Internal herniation a well-described late complication of this operation. Petersen’s hernia (PH) occurs within space, which iatrogenically created between transverse mesocolon, Roux limb, and retroperitoneum. The aims study were to investigate incidence symptomatic hernias (PH), determine risk factors for their occurrence, provide insight on eventual benefit systematic space closure...
Abstract Background Obesity is rapidly emerging as a significant epidemic in developing countries. Although promising therapeutics are development, bariatric surgery remains the most effective treatment. To better characterize this disease, waist and hip circumference measurements, waist-to-hip ratio were developed. These measures provide valuable insights into body fat distribution its associated health risks, enabling more accurate assessments targeted interventions. Methods A...
Abstract Introduction The incidence of small bowel obstruction (SBO) after Roux-en-Y gastric bypass (RYGB) ranges from 0.6% to 3.5%, with common causes being surgical adhesions, internal hernias, and anastomotic stenosis. Intraluminal clots causing are rare. A PubMed search for ‘small obstruction’ AND (‘haemobezoar’ OR ‘intraluminal clot’ ‘blood clot’) identified 27 cases reported between 2005 2024. This study presents three SBO due intraluminal at the jejuno-jejunostomy in patients who...
Abstract Introduction Single Anastomosis Duodena-Ileal Bypass with Sleeve Gastrectomy (SADI-S) has emerged as a simplified and effective alternative to the traditional duodenal switch. SADI-S eliminates alimentary limb, common channel is lengthened from 200 300 cm. This modification results in single ileo-duodenal anastomosis, reducing complexity potential complications associated multiple anastomoses, such internal hernias. can be done 1-stage surgery or 2-stage surgery. However, more...
Abstract Introduction Laparoscopic Roux-En-Y gastric bypass (LRYGB) is one of the most performed procedures for morbid obesity. Morbidity and mortality associated with bariatric surgery are considered low. Nevertheless, post-operative haemorrhage frequent early complication after LRYGB. Methods We conducted a retrospective cohort study regarding all patients submitted to LRYBG between 2019 2023 at our centre. Postoperative was defined as clinically significant evidence bleeding in...
Abstract Introduction Revision surgeries have become crucial in bariatric surgery, accounting for 7.4% of procedures 2016. Although sleeve gastrectomy (SG) has good short-term results, many patients require revisional surgery due to insufficient weight loss or functional complications. Options after SG include Roux-en-Y gastric bypass (RYGB), repeated gastrectomy, biliopancreatic diversion, duodenal switch, duodenal-jejunal bypass, one-anastomosis (SADI-S), single anastomosis duodeno-ileal...
Evidence supporting transmural remission (TR) as a long-term treatment target in Crohn's disease (CD) is still unavailable. Less stringent but more reachable targets such isolated endoscopic (IER) or radiologic (IRR) may also be acceptable options the long-term.Multicenter retrospective study including 404 CD patients evaluated by magnetic resonance enterography and colonoscopy. Five-year rates of hospitalization, surgery, use steroids, escalation were compared between with TR, IER, IRR, no...
Recognition of a hereditary colorectal cancer (CRC) syndrome is crucial and Lynch Syndrome (LS) the most frequent immunohistochemistry (IHC)-screening for mismatch repair proteins (MMR) deficiency in CRC therefore advocated. An unicentric cohort study was conducted central Oncological Hospital to assess its results. All patients under 70 years-old admitted between July 2017-June 2019 submitted surgery were included. Of 275 patients, 56.0% male, median age 61.0 (IQR:54.5-65.0), with...
SUMMARY Primary esophageal cancer (EC) frequently presents as a locally advanced disease with airway involvement. Placement of combined and stents has been reported in small series to be an effective palliation strategy. Our aims are present the largest cohort EC patients who underwent double stent evaluate safety efficacy this approach. Longitudinal study primary undergoing two-stage placement at oncology referral institute (January 2000–January 2019). Assessments: baseline demographics...
Locally advanced rectal cancer (LARC) poses a significantly challenge in clinical management, requiring multimodal treatment approach. Among innovative strategies, Total Neoadjuvant Therapy (TNT) has emerged, delivering all planned chemotherapy before surgery. Our aim was to evaluate the real-world application and efficacy of TNT compare it with non-TNT standard strategy. This retrospective study compared locally adenocarcinoma patients treated 2022 those who underwent traditional...
A 71-year-old woman was referred for treatment of a sessile polyp (0-Is) in the sigmoid described as having altered crypt morphology and disrupted vascular pattern on virtual chromoendoscopy, indicative malignancy. The endoscopic biopsies revealed no dysplasia.We repeated colonoscopy, polypoid lesion adjacent to diverticulum with large ostium identified. had pale color small ulceration white-light endoscopy, measuring 12 mm (Fig. 1). Narrow Band Imaging (NBI) assessment absence pit an...
INTRODUCTION: We aim to discuss the utility of self-expandable esophageal metal stent (SEMS) in variceal bleeding challenging cases. METHODS: Case description, discussion on patient management and decision-making process an uncommon situation, from a multidisciplinary point view. RESULTS: report case cirrhotic with refractory who underwent SEMS placement, which remained situ for 9 months. This decision was based initial poor status short life expectancy, limiting consideration other options...
