Article Synopsis
- Anorectal abscesses are common but can lead to serious health issues if they extend upwards, as seen in a case involving a 53-year-old woman with severe symptoms and acute kidney injury.
- Imaging revealed a large abscess affecting the retroperitoneal spaces, which required surgical drainage through a lower abdominal incision.
- The study suggests that a midline extraperitoneal approach can be an effective treatment for patients with extensive retroperitoneal abscesses, given their potential life-threatening nature.

- Assessment of gastrointestinal stromal tumors (GISTs) involves measuring maximum tumor size, mitotic index, and the Ki-67 labeling index, which indicates cell growth, with a Ki-67 value of 10% or higher suggesting worse prognosis.
- A study analyzed factors from 15 patients who had gastric stromal tumors, finding significant differences in tumor size, mitotic index, and Ki-67 values between patients with metastasis/recurrence and benign groups.
- The findings highlight that these indices are valuable for evaluating malignancy in gastric stromal tumors, while surgical removal may not be enough for patients with widespread metastasis.
A 64-year-old-male had recurrent paraaortic lymph node and liver metastases eight months after total gastrectomy and with distal pancreatectomy and splenectomy for advanced gastric cancer. Combined chemotherapy with 5-FU and a low-dose of CDDP was effective and the both lesions disappeared. Thirteen months later, a second recurrence of anterior mediastinum lymph node metastases occurred.
