RESUMO
Gastric cancer remains a significant global health challenge with varied survival rates, emphasizing the need for research into effective surgical treatments. In this retrospective study, we compared the 72-month overall and disease-free survival between laparoscopic gastrectomy (LG) and laparoscopic-assisted gastrectomy (AG) in a cohort of 139 patients treated for gastric cancer. The analysis revealed that patients undergoing LG exhibited a significantly higher overall survival rate at 72 months compared to those undergoing AG. Although disease-free survival rates were comparable between the two groups, LG showed a marginal advantage. Subgroup analyses based on the type of gastrectomy and anastomosis demonstrated varied survival probabilities, with laparoscopic-assisted partial gastrectomy yielding the most favorable outcomes. These results highlight the importance of the choice of surgical technique in influencing survival outcomes in gastric cancer.
RESUMO
Liver tumors rank as the fourth most common cause of cancer. This case report highlights a 45-year-old female patient who presented persistent abdominal pain and no other symptoms. Initially, she was approached with a probable hepatitis of unknown origin, but her condition worsened rapidly. An endoscopic ultrasound was used to characterize the lesion, and a fine needle biopsy of the lesion was performed which revealed a diffuse large B-cell lymphoma that is CD20+ and Ki67+. Hepatic diffuse large B-cell lymphoma, as diagnosed in the patient, is a rare type of lymphoma that arises in the liver. The treatment usually involves chemotherapy, immunotherapy, and radiation therapy. However, the prognosis depends on the stage of the disease and the patient's overall health. This case reinforces the importance of considering hepatic diffuse large B-cell lymphoma in differential diagnosis for primary liver neoplasia.
RESUMO
The evolution of laparoscopic surgery in gastric cancer has advanced significantly, with benefits over open surgery initially demonstrated in early gastric cancer and later in advanced stages. This study aims to evaluate postoperative complications, surgical outcomes, and anastomosis safety by comparing laparoscopic gastrectomy and laparoscopic-assisted gastrectomy. This retrospective, observational, analytical study included patients diagnosed with gastric cancer who underwent laparoscopic gastrectomy at a university hospital from January 2006 to February 2018. Patients were initially divided into two groups based on the type of anastomosis: laparoscopic gastrectomy (intracorporeal anastomosis) and laparoscopic-assisted gastrectomy (extracorporeal anastomosis). Further secondary analysis was done with subgroups based on the type of gastrectomy and anastomosis performed. A total of 139 patients were analyzed, showing significant differences in postoperative complications between the two surgical approaches. The laparoscopic-assisted group exhibited a higher rate of complications. The laparoscopic approach (with intracorporeal anastomosis) was found to have a lower risk of complications and morbidity/mortality compared to the laparoscopic-assisted approach. Laparoscopic gastrectomy with intracorporeal anastomosis resulted in lower morbidity and mortality than laparoscopic-assisted gastrectomy. The technique of partial gastrectomy with intracorporeal anastomosis was associated with the lowest rate of postoperative complications.
