[A Case of Gastric Cancer with Splenic Artery Aneurysm, Intraoperative ICG Fluorography Is Useful in Evaluating the Blood Flow of Stomach and Spleen].

An 81-year-oldwoman with advancedgastric cancer was referredto our hospital. Preoperative contrast-enhancedCT revealeda roundcalcification of the splenic hilum with 15mm in diameter as a splenic artery aneurysm. She underwent transcatheter arterial embolization(TAE)for the splenic artery aneurysm. Celiac artery angiography showedcollateral arterial network of the spleen from left gastric artery. Surgery for the gastric cancer was performed1 4 days after TAE. We cut the right gastric andbilateral epigastric arteries. After the left gastric artery clamping, we performedintraoperative indocyanine green(ICG)fluorography. ICG fluorography confirmedthat the bloodflow of the upper thirdof the stomach andspleen were maintained. We safely performed distal gastrectomy, and the postoperative course was uneventful.

[Compliance with FOLFOX4 for Stage III colon cancer in the adjuvant setting].

AIMS: The usefulness of oxaliplatin(L-OHP)as adjuvant chemotherapy for Stage III colon cancer has been shown in clinical trials, such as the MOSAIC trial. The Leucovorin, fluorouracil, and oxaliplatin(FOLFOX)regimen has been recommended as adjuvant chemotherapy for colorectal cancer in Japan. In the MOSAIC trial, 74.7% of patients completed all planned treatment cycles. Neurological toxicity caused byL -OHP is one of the factors for discontinuing treatment. Therefore, we planned to administer FOLFOX4 as postoperative adjuvant chemotherapy and evaluated the safety and feasibility of this regimen. METHODS: From November 2009, 13 patients with Stage III colon cancer who had undergone complete resection of a primary tumor were enrolled. Patients received 4 cycles of FOLFOX4, followed by 4 cycles of the simplified fluorouracil and Leucovorin (LV5FU2)regimen and 4 additional cycles of FOLFOX4(12 cycles in total). RESULTS: Thirteen patients were treated with our FOLFOX4 regimen. In total, 11 patients(84.6%)completed all 12 planned treatment cycles. The median L-OHP dose per patient was 560mg/m / 2(compared with the per-protocol 12-cycle dose of 680 mg/m2). Grade 1 neurological toxicity during treatment was reported in 10 patients(76.9%). Neurological toxicity was reduced during the 4 cycles without L-OHP. CONCLUSION: Our FOLFOX4 regimen showed reduced neurological toxicity compared to other trials and can be used safely.

Laparoscopic surgery for urachal remnants in pubescent children: a case series.

BACKGROUND: Various techniques are applied in laparoscopic surgery for the treatment of urachal remnants, which are less invasive and associated with lower morbidity. We herein report a case series in which we treated urachal remnants and medial umbilical ligaments using a laparoscopic approach. CASE PRESENTATION: From 2015 to 2019, seven patients (male, n = 5; female, n = 2) with a urachal remnant were treated by laparoscopic surgery in our institute. Five boys and two girls with a median age of 11 years (range 10-15 years) were enrolled in this series. The clinical results of laparoscopic treatment, the perioperative records, and the pathologic results were evaluated. The operation was performed with the use of three ports and an EZ access® (Hakko Medical, Nagano, Japan), which is a silicon cap for the wound retractor (Lap Protector®, Hakko Medical, Nagano, Japan). The removal of the urachal remnant and medial umbilical ligaments was completed with a median operative time of 92 min (range 69-128). The median hospital stay after surgery was 4 days (range 2-5). No patients developed intra-postoperative complications or recurrence. CONCLUSIONS: Although our data are preliminary, complete laparoscopic removal of symptomatic urachal remnants and medial umbilical ligaments was a safe and effective minimally invasive approach, with better cosmetic outcomes.

An extremely rare case of pancreatic metastasis of esophageal squamous cell carcinoma.

We report a rare case of a 68-year-old male with metachronous pancreatic metastasis that was resected 2 years after salvage esophagectomy for local recurrence of esophageal squamous cell carcinoma (ESCC). Two years and 8 mo ago, he had undergone definitive chemoradiotherapy for the lower thoracic ESCC and achieved a complete response. Chemoradiotherapy used the protocol of the Japan Clinical Oncology Group trial 9906. Approximately 8 mo later, he developed a local recurrence of the ESCC and underwent thoracoscopic salvage esophagectomy followed by reconstruction with a conduit colon graft via a subcutaneous route. Recently, a tumor of the pancreatic body was found on routine follow-up computed tomography (CT). The tumor diameter was 15 mm on CT, and the maximum standardized uptake value of the lesion was 5.49 at 18F-2-fluoro-2-deoxy-D-glucose positron-emission tomography, strongly suggesting pancreatic cancer. In addition, all tumor markers were within the reference intervals. Therefore, distal pancreatectomy was performed with the resultant histological diagnosis being confirmed as pancreatic metastasis of the ESCC. He was treated with adjuvant chemotherapy, and there has been no evidence of recurrence 9 mo after the surgery. Resection of pancreatic metastasis offers a good prognosis and should be considered for solitary ESCC metastasis.

Hepatic resection of giant metastatic tumor from clear cell carcinoma of the ovary.

All cancer patients, particularly those treated for colorectal cancer, should be monitored for the presence of liver metastases, but liver metastases from ovarian clear cell carcinoma are quite rare. We report a patient subjected to extended left hepatectomy due to a giant metastasis 5 years after surgical treatment for an ovarian neoplasm that was histopathologically diagnosed as clear cell carcinoma. A 58-year-old woman had undergone hysterectomy and bilateral salpingo-oophorectomy due to ovarian cancer (stage Ic). Four years and 8 months after the operation, a computed tomography (CT) scan demonstrated a giant tumor in the left lobe of the liver. The tumor compressed the inferior vena cava (IVC), but it was not clear whether it invaded the vessel. She received chemotherapy for 4 months; however, the tumor did not decrease in size. She was subsequently referred to our institution and was submitted to operation after it was confirmed that there were no distant metastases. After being subjected to an extended left hepatectomy and cholecystectomy, the patient recovered from the surgery without any complications. She has been carefully followed for 17 months and has presented no evidence of recurrence.

Living-donor liver transplantation for homozygous familial hypercholesterolemia from a donor with heterozygous hypercholesterolemia.

Familial hypercholesterolemia is a rare inherited disease with an incidence of approximately one per million. Severe hypercholesterolemia is observed from the time of birth onwards. It is associated with severe atherosclerosis in childhood, leading to death from myocardial infarction before the age of 20 years. Liver transplantation is the only effective treatment for this disease. We experienced the case of an infant aged 2 years 5 months who had homozygous familial hypercholesterolemia and who received a liver graft from his father, who had familial heterozygous hypercholesterolemia. The pre-operative plasma cholesterol level was >800 mg/dl. After liver transplantation, the recipient's cholesterol level decreased to 250 mg/dl after we administered the HMG-CoA reductase inhibitor. At present, 6 months after transplantation, the patient is doing well and free from a special diet. We can thus conclude that the combination therapy of liver transplantation from a donor with heterozygous familial hypercholesterolemia on cholesterol-lowering drugs is an effective therapy for a patient with the homozygous type of hypercholesterolemia.

The safety of the donor operation in living-donor liver transplantation: an analysis of 45 donors.

We retrospectively assessed the safety of the donor operation, based on parameters such as blood loss, blood transfusion, operation time, duration of hospitalization, and complications. Forty-five pediatric and adult recipients underwent living-donor liver transplantation (LDLTx) in Tohoku University Hospital from July 1991 to October 2000. Donor operations were classified into three groups. In the LS group, the graft was the lateral segment ( n=20); in the LL group, the graft was the left lobe without the middle hepatic vein ( n=16); and in the LLM group, the graft was the left lobe with the middle hepatic vein ( n=9). No significant differences were observed among the three groups regarding postoperative liver function or duration of hospitalization. In the LS group, the operation time was shorter and the requirement of autologous blood transfusion was significantly lower than in the other two groups. Most complications following retrieval of the graft were minor. Safety is guaranteed when the left lobe or the left lateral segment is used for LDLTx, but meticulous management of the operation is required to prevent complications.
