Treatment of diffuse large B-cell lymphoma (DLBCL) is based on immunochemotherapy with overall good outcomes. Complications related to the treatment or the disease itself can occur during follow-up. We herein report a case of a 37-year-old male who was diagnosed with stage IV gastric DLBCL. Subsequently, he underwent R-CHOP (rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisone) chemotherapy. After six cycles of treatment, complete remission has been achieved. But afterwards, the patient presented with a symptomatic gastric obstruction related to a tight stenosis in the antro-fundic junction. Endoscopic dilation was performed and multiple macrobiopsies within the stenosis were taken. Pathological examination concluded to the fibrous character of the stricture. In cases of post-chemotherapy obstruction in gastric DLBCL, endoscopic treatment should be attempted carefully in patients with no evidence of active lymphoma. Diagnosis of fibrosis can avoid surgery and its morbidity.

Concurrent malignant biliary and gastric outlet obstruction requires urgent palliative intervention to improve patient quality of life and permit systemic therapy. Traditional management has been surgical gastrojejunostomy and hepaticojejunostomy, two morbid procedures. Comparatively, endoscopic stenting can relieve both sites of obstruction with less complications and quicker recovery.

Pancreatic cancer is associated with high rates of morbidity and mortality. Endoscopic ultrasound (EUS)-guided biopsy has become the standard diagnostic modality per the guidelines. The use of EUS has been growing for providing various treatments in patients with pancreatic cancers: biliary and gallbladder drainage for those with malignant biliary obstruction, gastroenterostomy for malignant gastric outlet obstruction, celiac plexus/ganglia neurolysis for pain control, radiofrequency ablation, placement of fiducial markers, and injection of local chemotherapeutic agents.

Background: The impact of preoperative sarcopenia on postoperative outcomes in gastric cancer remains debated. This study aims to perform an in-depth meta-analysis and comprehensive review of the relationship between preoperative sarcopenia, as assessed by the Skeletal Muscle Mass Index (SMI), and postoperative complications and survival metrics in gastric cancer patients, to offer new insights into this issue.

Methods: We conducted a systematic search of primary studies in databases such as Embase, PubMed, and Web of Science, up to July 2024.

IS ESG EFFECTIVE IN THE TREATMENT OF OBESITY AND ASSOCIATEDCOMORBIDITIES?: Endoscopic Sleeve Gastroplasty (ESG) is more effective than lifestyle modifications alone for weight loss and improving obesity-related comorbidities. While it has less effect on weight loss compared to Laparoscopic Sleeve Gastrectomy (LSG) in the short to medium term, it offers similar comorbidities resolution to LSG. IS ESG A SAFE PROCEDURE, AND WHAT ARE ITS RISKS?: The safety profile of ESG is consistently supported in the literature.
