[Long-Term Suppression with First-Line Chemotherapy(FOLFIRI plus BV)for Peritoneal Metastasis].

A 72-year-old man underwent right hemicolectomy for transverse colon cancer(pT4aN1aM0, Stage ⅢB), after which he received adjuvant chemotherapy(capecitabine plus oxaliplatin[CAPOX])for 6 months. Three years after the first surgery, FDG-PET/CT revealed a tumor in the abdomen. He underwent a tumorectomy and adjuvant chemotherapy(CAPOX plus bevacizumab[BV])performed for 6 months. Two years after a tumorectomy, the CEA level rose again. He was diagnosed peritoneal metastasis again. A central venous(CV)port was implanted for access to the right internal jugular vein, and he received systemic chemotherapy(fluorouracil, Leucovorin, and irinotecan[FOLFIRI]plus BV)as an outpatient. One year after this recurrence, no peritoneal dissemination was detected by CT. Thereafter, total 49 courses of FOLFIRI plus BV were introduced, but chemotherapy was discontinued due to CV port-related infection. Three months later, low back pain appeared and became a diagnosis of spondylodiscitis. He had surgery, but follow-up CT performed 8 years after the first surgery detected multiple liver metastasis. It was considered necessary to take infection control measures during long-term chemotherapy.

[A Case of Jejunal Ectopic Pancreas Incidentally Found in Laparoscopic Rectal Cancer Surgery].

In laparoscopic surgery, intraabdominal examination is occasionally difficult due to restriction of operative field and palpation. This is a case report of a jejunal ectopic pancreas which was incidentally found during laparoscopic surgery. A 49-year- old male underwent endoscopic mucosal resection for a rectal polyp which pathologically resulted in 5,000 µm invasion in submucosa and lymphatic invasion. Laparoscopic low anterior resection was planned for the patient as an additional treatment. During the surgery, irregular shaped tumor-like lesion was incidentally found in jejunum which was located 30 cm distal side from the ligament of Treitz. Partial resection of jejunum was also performed for pathological diagnosis. Resected jejunal lesion was pathologically diagnosed as an ectopic pancreas of Heinrich classification type Ⅰ. Ectopic pancreas is defined as pancreatic tissue which is discontinuous to pancreas, asymptomatic in most cases, but some reported cases of pancreatitis, forming fistula or cancerous change. Reporting with some literature review.

[A Case of Meningeal Carcinomatosis of Gastric Cancer Successfully Controlled with Nab-Paclitaxel].

We report a 76-year-old woman with meningeal carcinomatosis after gastric cancer surgery. During adjuvant chemotherapy, metastasis to the left axillary and Virchow's lymph node was suspected. A resection biopsy revealed gastric cancer metastasis, and PTX plus RAM therapy was started. Due to RAM adverse events, the treatment was changed to weekly nab- PTX, which was continued for about 6 months. During the 8th course, she was hospitalized due to worsening headache and lightheadedness. Meningeal carcinomatosis was diagnosed by cytology of CSF examination and MRI findings. She died on the 16th day after admission. Meningeal carcinomatosis has a rapidly progressive course with poor prognosis. This case shows nab-PTX may have been able to control the progression.

[A Case of Descending Colon Cancer with Virchow and Axillary Lymph Node Metastasis].

A 72-year-old man was referred to our department with suspected intestinal obstruction. CT showed irregular descending colon wall thickening. Lower endoscopy showed severe descending colon stenosis. Biopsy results were group 1. FDG accumulation of significant SUV was found in the lymph nodes on the left supraclavicular region, left axilla, right mediastinum, posterior part of the right diaphragmatic leg, around the abdominal aorta, and in the liver. The accumulation in the descending colon was not definitely neoplastic. Consequently of left axillary lymph node biopsy, axillary lymph node metastasis of colorectal cancer was suspected, and laparoscopic left semicolon resection was performed. Among the simultaneous distant colorectal cancer metastases, Virchow's and left axillary lymph node metastases are extremely rare(0.1%). We report a case of descending colon cancer with simultaneous Virchow's and left axillary lymph node metastases, with some literature discussion.

[A Case Report of Carcinoma of the Appendix Which Was Diagnosed with Ascites One Year after Appendicitis Operation].

A 68-year-old man visited our hospital in October 201X, giving abdominal bloating as his primary symptom. We found tenderness at McBurney's point, high WBC values from a blood test, and swelling of the appendix in a CT scan, so he was diagnosed with acute appendicitis. On the same day, he had an emergency laparoscopic appendectomy, and he made good progress and was discharged from the hospital on the fourth day after the surgery. In the histopathological examination, he was diagnosed with acute gangrenous appendicitis and examination was concluded. August of the following year, ascites accumulation was found by CT scan, and he was introduced to the department of gastroenterology of this hospital for further testing. Lower endoscopy showed swelling of the appendix root, and he was diagnosed with adenocarcinoma in the biopsy. A CT scan found increased granular concentration in the omentum. Because of a diagnosis of appendix cancer/peritoneal dissemination, he underwent laparoscopic examination in October. Nodules were found scattered in the small intestinal mesentery and the omentum, and peritoneal dissemination was suspected during intraoperative rapid diagnosis. The operation was concluded with only laparoscopic examination. Because of the diagnosis of appendix cancer/peritoneal dissemination, mFOLFOX6 plus bevacizumab was implemented. Primary appendix cancer is a relatively rare disease, often diagnosed after surgery for appendicitis, reported of here 0.03% to 0.5% of cases undergoing appendectomy. We report a case of primary appendix cancer diagnosed 1 year after appendectomy, with the discussion of the literature.

[A Case of Neuroendocrine Tumor of the Second Part of the Duodenum].

A 69-year-old woman was referred to our hospital when the upper gastrointestinal endoscopy performed by the previous physician for detailed examination of upper abdominal discomfort indicated a duodenal tumor. Upper gastrointestinal endoscopy revealed a submucosal tumor with a central depression in the descending part of the duodenum. Contrast- enhanced computed tomography of the abdomen revealed a 23 mm tumor with contrast effect in the descending part of the duodenum contralateral to the Vater papilla. There was no lymphadenopathy or distant metastasis. Duodenal gastrointestinal stromal tumor was suspected, and localized duodenectomy was planned. Intraoperative findings showed that the tumor was located in the descending part contralateral to the Vater papilla with no evidence of surrounding invasion. Localized duodenectomy was performed, and on intraoperative rapid histopathological examination, an adenocarcinoma was suspected. As a result, the surgery was changed into pancreaticoduodenectomy. Based on the results of immunostaining, neuroendocrine tumor grade 2 was diagnosed. No lymph node metastasis was observed. The patient did not have recurrence of lesion 7 months after surgery.

Endo Mini-Retract(TM) laparoscopic retractor with a novel short-cut Nelaton catheter for dividing the vasculature in laparoscopic liver resection.

Laparoscopic hepatectomy has become a widespread procedure in Japan, now that the national medical insurance system covers partial resection and lateral segmentectomy. An important procedure during laparoscopic hepatectomy is the division of the vascular pedicles. In this paper we report a practical and useful method for vascular division with an Endo Mini-Retract(TM) retractor and a shortened Nelaton catheter (2.5-mm-diameter) developed in our department.
