[A Case of Two-Stage Radical Resection with Neoadjuvant Chemotherapy for Cecal Cancer with Synchronous Peritoneal Metastasis(P3)].

A 63-year-old female patient was diagnosed with cecal cancer(cT3, N2a, M0)and underwent surgery for the first time. Only laparoscopic ileocecal resection(D3 dissection)was performed because intraperitoneal observation revealed peritoneal metastasis around the tumor and uterus. We decided to perform a radical resection because the peritoneal metastasis was localized by FDG-PET/CT. Five courses of neoadjuvant chemotherapy(mFOLFOX6)were performed to shrink the tumor. Unrecognized peritoneal metastases were found in other areas during the second surgery. Although the extent of the peritoneal metastasis was P3, all lesions had been resected. No perioperative complications occurred, and adjuvant chemotherapy was administered to the patient. Recurrence was not observed until 6 months postoperatively.

Manual laparoscopy-assisted intraoperative reduction for adult ileocolic intussusception with ileal adenoma: A case report.

INTRODUCTION: Adult intussusception is a rare condition with a pathological lead point. Intraoperative reduction of adult intussusception can eliminate the need for extensive or invasive resection. We safely performed a manual laparoscopy-assisted intraoperative reduction that allowed functional preservation of tissue. PRESENTATION OF CASE: A 70-year-old woman with dull right lumbar pain at regular intervals and right lower quadrant abdominal tenderness was admitted to our hospital. The ileum exhibited enhanced wall thickening and invagination into the ascending colon on computed tomography. Emergency laparoscopic surgery was chosen to treat the ileocolic intussusception. First, the right colon was mobilized. Second, the ileocecal region was pulled through a 4-cm right pararectus incision. Third, the edge of the intussusceptum was gently manipulated back upstream without tearing. After reduction, a soft mass was recognized on palpation at the lead point, located 10cm proximal to the ileocecal valve. Ileocecal resection was performed, and a laterally spreading tumor was observed in the resected specimen. The histological diagnosis was high-grade tubular adenoma. The postoperative course was uneventful. DISCUSSION: Adult intussusception has a pathological lead point, and curative treatment generally includes resection of the lesion. Complete or partial intraoperative reduction can avoid or shorten bowel resection and allow functional preservation of the tissue. CONCLUSION: Manual laparoscopy-assisted intraoperative reduction with a minilaparotomy was safely performed, which eliminated the need for extensive or invasive resection.

Anatomical hepatectomy for liver metastasis from rectal adenocarcinoma presenting with intrabiliary extension: a case report.

Liver metastases from colorectal carcinoma commonly form nodular lesions in the liver parenchyma. We report a case of liver metastasis from rectal adenocarcinoma that extended predominantly into the bile duct. A 62-year-old Japanese man underwent low anterior resection for rectal adenocarcinoma 9 years ago. Approximately 3 years later, he underwent radiofrequency ablation therapy for a metastatic liver tumor. Nine years after surgery, a tumor in liver segment III exhibiting intrabiliary extension was discovered; it was unclear if this was a metastatic liver tumor or intrahepatic cholangiocarcinoma. Accordingly, we performed a left hepatectomy with lymph node dissection. The tumor was negative for cytokeratins 7 and 20, and was histologically similar to the primary rectal adenocarcinoma; it was diagnosed as rectal carcinoma metastasis. The patient has survived for 3 years after the hepatic surgery, for 9 years after radiofrequency ablation therapy, and for 12 years after the primary surgery. This case shows that liver metastasis from colorectal carcinoma can present as a predominantly intrabiliary growth that mimics intrahepatic cholangiocarcinoma on imaging. Moreover, our case provides evidence for the superiority of anatomical hepatectomy over partial hepatectomy for metastatic liver tumors with intrabiliary growth arising from rectal adenocarcinomas.
