ABSTRACT
INTRODUCTION AND IMPORTANCE: Sclerosing angiomatoid nodular transformation (SANT) of the spleen is an extremely rare benign lesion. CASE PRESENTATION: Here, we describe the case of a 52-year-woman who was diagnosed with sclerosing angiomatoid nodular transformation of the spleen. Abdominal contrast-enhanced CT revealed a solid lesion in the splenic hilum that was slowly enhanced between the portal venous and equilibrium phases incidentally. Fluorodeoxyglucose positron emission tomography (FDG-PET) revealed FDG accumulation within the mass, with a maximum standardized uptake value (SUVmax) of 2.57. Based on these findings, the patient was scheduled for laparoscopic splenectomy. The total operating time was 193 min, and the intraoperative blood loss was 20 ml. The resected specimen was 9.0 × 8.4 × 5.6 cm and dark brown in colour with a large central stellate fibrotic scar. CLINICAL DISCUSSION: Pathological examination revealed nodular angioma lesions and the proliferation of fibrotic interstices and inflammatory cells. We could diagnose the SANT by the only HE staining without Immunohistochemical staining. CONCLUSION: Although SANT is a rare benign lesion, which is difficult to definitively diagnose based on preoperative imaging findings alone, it should be considered in cases of solitary splenic lesions, and we recommend performing LS and subsequent histological examination for the diagnosis of this disease.
ABSTRACT
INTRODUCTION AND IMPORTANCE: The laparoscopic posterior approach adapts the advantages of Kugel hernioplasty, making it possible to perform it at the new layer even if the inguinal hernia is recurrent following the anterior approach, producing a high level of completion. However, in laparoscopic surgery for recurrent inguinal hernia using posterior approaches, dissecting the extraperitoneal space is difficult. Robotic surgery may enable precise dissection, even if the space is severely adhered. Here, we report a robotic approach after extraperitoneal approach for recurrent inguinal hernia, which developed after Kugel hernioplasty. CASE PRESENTATION: A 78-year-old Japanese man, who underwent left inguinal hernia repair (Kugel hernioplasty) 2 years ago, presented with recurrent reducible left inguinal swelling. A peritoneal incision was created above the deep inguinal ring to treat the primary right inguinal hernia. The pressure in the left inguinal region revealed a spermatic cord lipoma protruding from the internal inguinal ring as a recurrent inguinal hernia of the abdominal cavity. CLINICAL DISCUSSION: Robotic transabdominal preperitoneal repair for recurrent inguinal hernia is effective, especially after posterior approach Kugel hernioplasty, in which dissection of the extraperitoneal space is difficult. In the present case, the peritoneal flap was conserved without removing the direct Kugel patch. CONCLUSION: Kugel hernioplasty, which is a posterior approach, would result in severe extraperitoneal space adhesion. Essentially, a new and previously unused approach is preferable to the previous approach in patients with recurrent inguinal hernias. Robotic approach is effective for recurrent inguinal hernias even if the space was severe adhesion.
