ABSTRACT
Pseudoaneurysm is a potentially life-threatening complication after hepatobiliary pancreatic surgery. Although various measures have been taken to prevent the formation of postoperative pseudoaneurysms, completely avoiding complications can be difficult. An 83-year-old man underwent bile duct resection and systematic regional lymphadenectomies for distal cholangiocarcinoma. Polyethylene glycolic acid mesh with fibrin glue was applied to the pancreas around the distal stump and detached artery to prevent leakage of pancreatic juice and reinforce the arterial wall. Screening contrast-enhanced computed tomography on the 7th postoperative day indicated no pseudoaneurysm. The patient was discharged on the 20th postoperative day after an uneventful course. However, 4 days later, the patient visited the emergency outpatient department with a complaint of fever. Contrast-enhanced computed tomography revealed an abscess formation and a pseudoaneurysm around it. Emergency celiac arteriography revealed two pseudoaneurysms at the left hepatic artery and posterior superior pancreaticoduodenal artery; they were successfully treated with transcatheter arterial embolization using microcoils and covered stent placement. The patient was discharged 9 days after interventional radiology treatment. At the 14 months postoperative follow-up, the patient had no recurrence or stent obstruction. Multiple synchronous pseudoaneurysms are rare; accurately identifying the site by angiography and selecting appropriate treatment for each site is important.

Liver cancer, including hepatocellular carcinoma (HCC), is the fifth most common cause of cancer deaths in Japan. The main treatment options for HCC are surgical resection, liver transplantation, radiofrequency ablation (RFA), transarterial chemoembolization (TACE), and systemic chemotherapy. Here, recent medical treatments for HCC, including surgery, percutaneous ablation, transcatheter arterial chemoembolization/transcatheter arterial embolization, and drug therapy, are reviewed with a focus on Japan.

Simple hepatic cysts are typically saccular, thin-walled masses with fluid-filled epithelial lined cavities. They arise from aberrant bile duct cells that develop during embryonic development. With the development of diagnostic modalities such as ultrasonography (US), CT, and MRI, simple hepatic cysts are frequently detected in clinical examinations. US is the most useful and noninvasive tool for diagnosis of simple hepatic cysts and can usually differentiate simple hepatic cysts from abscesses, hemangiomas, and malignancies. Cysts with irregular walls, septations, calcifications, or daughter cysts on US should be evaluated with enhanced CT or MRI, to differentiate simple hepatic cysts from cystic neoplasms or hydatid cysts. Growth and compression of hepatic cysts cause abdominal discomfort, pain, distension, and dietary symptoms such as nausea, vomiting, a feeling of fullness, and early satiety. Complications of simple hepatic cysts include infection, spontaneous hemorrhage, rupture, and external compression of biliary tree or major vessels. Asymptomatic simple hepatic cysts do not require treatment. Treatment for symptomatic simple hepatic cysts includes percutaneous aspiration, aspiration followed by sclerotherapy, and surgery. The American College of Gastroenterology clinical guidelines recommend laparoscopic fenestration because of its high success rate and low invasiveness. Percutaneous procedures for treatment of simple hepatic cysts are particularly effective for immediate palliation of patient symptoms; however, they are not generally recommended because of the high rate of recurrence. Management of simple hepatic cysts requires correct differentiation from neoplasms and infections, and selection of a reliable treatment.

PURPOSE: Portal vein thrombosis (PVT) following hepatectomy is potentially life-threatening. We aimed to evaluate the incidence of PVT after hepatectomy for hepatocellular carcinoma and identify coagulation and fibrinolytic factors that could predict early-stage postoperative PVT. METHODS: A retrospective analysis was conducted on 65 hepatocellular carcinoma patients who underwent radical hepatectomy. The risk factors for postoperative PVT were identified based on univariate and multivariate analyses, and the levels of coagulation and fibrinolytic factors were measured during the perioperative period. RESULTS: The incidence of PVT after hepatectomy was 20.0%. The patients were divided into two groups: those with PVT (n=13; PVT group) and those without PVT (n=52; no-PVT group). The frequency of the use of the Pringle maneuver during surgery was higher in the PVT group than in the no-PVT group, and the postoperative/preoperative ratios of thrombin-antithrombin III complex (TAT) and of D-dimer were significantly higher in the PVT group. CONCLUSION: A high incidence of PVT was found in hepatocellular carcinoma patients after hepatectomy. The frequency of the Pringle maneuver is a potential risk factor for postoperative PVT, and the postoperative/preoperative TAT and D-dimer ratios may be used as early predictors of PVT after hepatectomy for hepatocellular carcinoma.

BACKGROUND: The Pringle maneuver is often used in liver surgery to minimize bleeding during liver transection. Many authors have demonstrated that intermittent use of the Pringle maneuver is safe and effective when performed appropriately. However, some studies have reported that the Pringle maneuver is a significant risk factor for portal vein thrombosis. In this study, we evaluated the effectiveness of portal vein flow after the Pringle maneuver and the impact that massaging the hepatoduodenal ligament after the Pringle maneuver has on portal vein flow. MATERIALS AND METHODS: Patients treated with the Pringle maneuver for hepatectomies performed to treat hepatic disease at our hospital between August 2014 and March 2019 were included in the study (N = 101). We divided these patients into two groups, a massage group and nonmassage group. We measured portal vein blood flow with ultrasonography before and after clamping of the hepatoduodenal ligament. We also evaluated laboratory data after the hepatectomy. RESULTS: Portal vein flow was significantly lower after the Pringle maneuver than before clamping of the hepatoduodenal ligament. The portal vein flow after the Pringle maneuver was improved following massage of the hepatoduodenal ligament. After hepatectomy, serum prothrombin time was significantly higher and serum C-reactive protein was significantly lower in the massage group than in the nonmassage group. CONCLUSION: Massaging the hepatoduodenal ligament after the Pringle maneuver is recommended in order to quickly recover portal vein flow during hepatectomy and to improve coagulability.

Before the first laparoscopic hepatectomy (LH) was described in 1991, open hepatectomy (OH) was the only choice for surgical treatment of liver tumors. LH indications were initially based solely on tumor location, size, and type. Use of LH has spread rapidly worldwide because it reduces incision size. This review systematically assesses the current status of LH. As compared with OH, LH is significantly less complicated, requires shorter hospital stays, and results in less blood loss. The long-term survival rates of LH and OH are comparable. Development of new techniques and instruments will improve the conversion rate and reduce complications. Furthermore, development of surgical navigation will improve LH safety and efficacy. Laparoscopic major hepatectomy for HCC remains a challenging procedure and should only be performed by experienced surgeons. In the near future, a training system for young surgeons will become mandatory for standardization of LH, and LH will likely become better standardized and have broader applications.

INTRODUCTION: The common metastatic sites of renal cell cancer (RCC) are the lung, bone, liver, brain, adrenal glands, and contralateral kidney. Metastasis to the gallbladder is rare, and cystic duct metastasis from RCC has been reported in only one metachronous case. This is the first report of a case of synchronous cystic duct metastasis from RCC. CASE REPORT: A 72-year-old woman presenting with hematuria had a history of Cushing disease approximately 10 years previously. Enhanced computed tomography of the abdomen showed a mass measuring 5.8 × 3.0 cm in the left kidney, which was strongly enhanced in the early phase and washed out in the late phase. A mass measuring 2 cm in diameter was seen in the left adrenal gland, and a 1.0-cm mass was noted in the right adrenal gland. Multiple tiny masses were detected in the cystic duct. Left renal cell carcinoma, cystic duct metastasis, and bilateral adrenal gland metastases were diagnosed. Because the metastatic tumor was close to the common bile duct, we performed left nephrectomy, bilateral adrenalectomy, cholecystectomy, resection of the extrahepatic bile duct, and hepaticojejunostomy. Pathological findings showed that the renal tumor was clear cell carcinoma, as were the bilateral adrenal tumors and cystic duct tumor. The patient died 30 months after the operation.

We report a case of metastatic pancreatic-head mucinous carcinoma (with multiple lymph node and bone metastases) and review the relevant literature. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) was useful for diagnosis, and a satisfactory outcome was achieved after systemic chemotherapy with FOLFIRINOX followed by resection of the primary lesion as conversion surgery. The patient was a 55-year-old man. Hematological findings included elevated serum tumor marker levels: CEA 12.7 ng/mL, DUPAN-2 400 U/mL. Findings from several imaging modalities and EUS-FNA confirmed a clinicopathological diagnosis of metastatic pancreatic mucinous carcinoma with multiple bone and lymph node metastases. Five courses of modified FOIFIRINOX (m-FFX) were given as systemic chemotherapy, which had an antitumor effect. Subtotal stomach-preserving pancreaticoduodenectomy and extensive lymph-node dissection were thus performed. Histopathological analysis showed invasive ductal carcinoma, muc (pT3, pN1b, cM1). After surgery, the clinical course was notable for the absence of complications. Tegafur/gimeracil/oteracil (S-1) was started as maintenance adjuvant chemotherapy postoperatively, and no disease progression has been observed at 10 months after surgery.

BACKGROUND: Intrahepatic arterioportal fistula (IAPF) is a rare cause of portal hypertension. Interventional radiology (IVR) is generally selected as the first-line therapeutic option. Surgical treatment for IAPF is required in refractory cases of IVR. As the treatment success rate with IVR is high, cases requiring surgical treatment are extremely rare. CASE PRESENTATION: A 54-year-old man was admitted to another hospital complaining of hematemesis due to rupture of the esophageal varices. A computed tomography revealed ascites and arterioportal fistula in the left lobe of the liver. Transcatheter arterial embolization (TAE) was performed to occlude the fistula; however, it could not reach complete occlusion. Thereafter, there were a total of four hematemeses, and six endoscopic variceal ligations were required. The second TAE also failed to reach complete occlusion. He was transferred to our hospital for further treatment. Because liver function was low due to frequent hematemeses and there was also uncontrollable ascites, it was confirmed that hepatectomy could not be performed safely at this time. Therefore, we ligated the left portal branch and ligated and dissected the left gastric vein to decrease portal vein pressure. However, on the 5th day after surgery, the esophageal varices reruptured. As the disappearance of ascites was observed in the postoperative course and the general condition also improved, left hepatectomy was performed to remove IAPF. There was no recurrence of portal hypertension for 1 year and 3 months since hepatectomy. CONCLUSIONS: This case was difficult to treat with IVR and required surgical treatment. Our experience in the present case suggests that hepatectomy to remove arterioportal fistula was considered effective for improving portal hypertension due to IAPF. However, careful treatment selection according to the patient's overall condition and clinical course is necessary for IAPF presenting with severe portal hypertension.
ABSTRACT
At present the only method available to confirm microscopic infiltration of cancer into ductal margins during surgery, is intraoperative histological examination. In the present study, the status of the surgical margins and postoperative course were evaluated to determine any correlation between remnant carcinoma and postoperative survival. All consecutive patients who underwent resection for biliary tract cancer between January 2004 and May 2012 were identified from a database. Positive margin cases were divided into two groups, invasive carcinoma and carcinoma in situ (CIS). Immunohistochemical staining targeting Ki67 and p53 for positive margins was performed. Cases of major vessel invasion were significantly increased in the positive group compared with the negative group. The recurrence rate was significantly lower in the CIS group compared with the invasive group. The survival rate was significantly increased in the CIS group compared with the invasive group. The expression levels of p53 and Ki67 were significantly increased in the invasive group compared with the CIS group. No statistical correlations were observed between the expression of p53 or Ki67 and the survival or recurrence of disease. In the positive group, resected margin status was the principal factor associated with recurrence-free survival according to Cox-regression analysis. In conclusion, the status of the resected margins in the positive group was the most important factor for postoperative survival and recurrence in cholangiocarcinoma, not immunohistochemical staining targeting Ki67 and p53.
ABSTRACT
BACKGROUND: Recently, some reports have revealed a relationship between post-hepatectomy prognosis in hepatocellular carcinoma (HCC) and hepatic fibrosis markers. We evaluated the relationship between these markers of hepatic fibrosis, clinicopathological findings, and prognosis. METHODS: Three hundred and sixty patients underwent hepatectomy for HCC in the Nippon Medical School Hospital between 1993 and 2013. We divided these patients into two groups: normal serum hyaluronic acid (HA) levels and abnormal levels. We also divided patients into groups with normal serum type IV collagen levels and abnormal levels. RESULTS: The overall survival rate and recurrence-free survival rate of the normal group were significantly higher than those of the abnormal group. In the normal hyaluronic acid group, serum albumin and prothrombin time were significantly higher than in the abnormal group, and age, hepatitis C virus antibody (HCV)-Ab positivity, Child-Pugh grade B, liver cirrhosis, indocyanine green retention rate at 15 min (ICGR15), type IV collagen level, and type IV collagen 7s level were significantly lower than those in the abnormal group. In the normal type IV collagen group, HCV-Ab positivity, liver cirrhosis, ICGR15, HA level, and type IV collagen 7s level were significantly lower than those in the abnormal group, and the serum albumin level was significantly higher than that in the abnormal group. Multivariate analysis independently revealed the significant effect of serum type IV collagen on the overall survival rate as well as the significant effect of serum HA on the recurrence-free survival rate in patients who underwent hepatectomy for HCC. CONCLUSIONS: Preoperative examinations of serum hyaluronic acid levels and type IV collagen levels are imperative for hepatic resection for HCC because these markers are significantly associated with liver function and prognosis.

We report here a rare case of intestinal obstruction caused by a peach seed. A 15-year-old boy was admitted to our hospital because of abdominal pain and vomiting. The patient had no history of previous gastrointestinal surgery and his medical comorbidity was autism. A computed tomography (CT) scan showed an obstruction of the ileum by a foreign body. Surgical treatment was successfully performed, and we found a peach seed in the ileum. He was discharged eight days after the operation without postoperative complications. Intestinal obstruction caused by plant seeds without gastrointestinal disease is rare.
ABSTRACT
Cutaneous metastasis of an internal malignancy is uncommon and is estimated to occur in 0.7-9% of patients with internal cancer including autopsy cases. We would like to report a case of long survival of sigmoid colon adenocarcinoma diagnosed as an instance of facial cutaneous metastasis. A 68-year-old male was admitted to our hospital for a tumor mass on the left side of his cheek. In his past history, acute myocardial infarction had occurred 2 years earlier. He also had chronic renal failure and chronic obstructive pulmonary disease. Histologic findings from the biopsy sample of this facial lesion were moderately differentiated adenocarcinoma. Colonoscopy revealed a tumor 20 mm × 30 mm in diameter in the sigmoid colon. Histologic findings of the biopsy sample of this tumor also indicated moderately differentiated adenocarcinoma. The patient was diagnosed with sigmoid colon cancer with cutaneous metastasis to the face. We performed a sigmoidectomy with lymph node dissection and resection of the facial cutaneous metastasis. After being discharged, low dose chemotherapy was performed in consideration of the patient's renal function. Although long-term management of his general condition was provided, the patient died 37 months after surgery because of chronic heart failure.

In islet transplantation, in addition to immunologic and ischemic factors, the diabetic/hyperglycemic state of the recipient has been proposed, although not yet validated, as a possible cause of islet toxicity, contributing to islet loss during the engraftment period. Using a miniature swine model of islet transplantation, we have now assessed the effect of a persistent state of hyperglycemia on islet engraftment and subsequent function. An islet-kidney (IK) model previously described by our laboratory was utilized. Three experimental donor animals underwent total pancreatectomy and autologous islet transplantation underneath the renal capsule to prepare an IK at a load of ≤1,000 islet equivalents (IE)/kg donor weight, leading to a chronic diabetic state during the engraftment period (fasting blood glucose >250 mg/dL). Three control donor animals underwent partial pancreatectomy (sufficient to maintain normoglycemia during islet engraftment period) and IK preparation. As in vivo functional readout for islet engraftment, the IKs were transplanted across an immunologic minor or class I mismatch barrier into diabetic, nephrectomized recipients at an islet load of â¼4,500 IE/kg recipient weight. A 12-d course of cyclosporine was administered for tolerance induction. All experimental donors became diabetic and showed signs of end organ injury, while control donors maintained normoglycemia. All recipients of IK from both experimental and control donors achieved glycemic control over long-term follow-up, with reversal of diabetic nephropathy and with similar glucose tolerance tests. In this preclinical, large animal model, neither islet engraftment nor subsequent long-term islet function after transplantation appear to be affected by the diabetic state.

Portal vein thrombosis (PVT) is a rare complication of liver transplantation which can lead to graft failure and patient death. Treatment can be difficult, especially in cases of PVT from the intrahepatic portal vein to the proximal jejunal veins. A 55-year-old woman had undergone living-donor liver transplantation with splenectomy for end-stage liver cirrhosis due to hepatitis C with hepatocellular carcinoma. Ten months after transplantation, massive ascites and slight abdominal pain developed, and computed tomography revealed a PVT between the intrahepatic portal vein and the superior mesenteric vein. Repeated interventional radiology procedures were used in combination with thrombolysis, thrombectomy, and metallic stent replacement to obtain favorable portal flow to the graft. Five years after being treated, the patient is well, with favorable portal flow having been confirmed. In conclusion, repeated and assiduous interventional radiological treatment combined with thrombolytic therapy, thrombectomy, and metallic stent replacement could be important for severe PVT.

The uterus, ovary, and fallopian tube are rarely present in an inguinal hernia. We report on an operation to treat just such a rare condition for a right inguinal hernia. An 87-year-old Japanese woman was admitted with swelling in the right inguinal region and a purulent discharge from the vagina. Vital signs were stable, but the mobile mass was irreducible. Computed tomography of the abdomen indicated uterine tissue in a right inguinal hernia. We diagnosed an inguinal hernia with an incarcerated uterus and performed surgery on that basis. An incision approximately 6 cm long was made in the skin above the swollen area to open the inguinal sac, disclosing a tumor enveloped by a hernial sac. Opening the hernial sac revealed the prolapsed uterus, the fallopian tube, and the right ovary. Because no ischemic change was noted, the incarcerated uterus was returned to the abdominal cavity, and the hernial opening was closed with the onlay mesh technique. The posterior wall of the inguinal canal was found to have prolapsed laterally to the inferior epigastric artery, resulting in an external inguinal hernia. This case demonstrates that careful attention must be paid to inguinal hernias in female patients because the uterus, ovary, and fallopian tube may be involved.

BACKGROUND: A clear operative view of the middle and lower mediastinum is possible in prone position during video-assisted thorocoscopic surgery of esophagus (VATS-E), but the working space in the upper mediastinum is limited and lymph node dissection along the left recurrent laryngeal nerve (RLN) is difficult in this position. METHODS: Esophagectomy and lymph node dissection are performed for pneumothorax by maintaining CO2 insufflation in the prone position. Working space in the left upper mediastinal area for lymph node dissection around RLN is limited in this position. To create space, the residual esophagus is stripped in the reverse direction and retracted toward the neck after the stomach tube is removed through the nose. Lymph node dissection is performed after stripping the residual esophagus. RESULTS: We could obtain a clear operative field in the upper left mediastinum by stripping the residual esophagus in the prone position, enabling safe and straightforward lymph node dissection along the left RLN. The rate of permanent RLN paralysis was 1.2%. CONCLUSIONS: Lymph node dissection along the left RLN after esophageal stripping is possible in the prone position during VATS-E.
ABSTRACT
Gallstone ileus is a rare complication of cholecystolithiasis, with the majority of cases requiring surgical treatment. In this paper, we describe a case of gallstone ileus that was successfully treated twice with conservative therapy. An 85-year-old woman was admitted to our hospital because of abdominal pain and vomiting. She had previously been treated with antibiotics for cholecystitis arising from 2 gallbladder stones. Computed tomography (CT) revealed that the small bowel was dilated and that 1 of the gallbladder stones had disappeared. In addition, a 28×22-mm calcified mass was found in the small-bowel lumen. We diagnosed gallstone ileus and performed nasogastric drainage for decompression. Follow-up CT revealed migration of the impacted stone, and symptoms had improved. However, 2 months after discharge, the patient's symptoms recurred. A CT scan revealed that the small bowel was again dilated and that the remaining gallstone had disappeared from the gallbladder. A 28×25-mm calcified mass was found in the small-bowel lumen. We diagnosed recurrent gallstone ileus. Because the gallstone was almost the same size as the previous one, we selected the same conservative decompression treatment. Fourteen days after the patient was admitted, the stone was evacuated with the feces. Although many cases of gallstone ileus require surgical treatment, spontaneous passage was achieved in this case. When treatment is chosen for gallstone ileus, the patient's presentation and clinical course must be considered.

A 70-year-old man who underwent two sessions of thoracoscopy-assisted ligation of the thoracic duct to treat refractory chylorrhea after radical esophagectomy for advanced esophageal cancer received conservative therapy. However, there was no improvement in chylorrhea. Then, transabdominal ligation of the lymphatic/thoracic duct at the level of the right crus of the diaphragm was performed using fluorescence navigation with indocyanine green (ICG). The procedure successfully reduced chylorrhea. This procedure provides a valid option for persistent chylothorax/chylous ascites accompanied by chylorrhea with no response to conservative treatment, transthoracic ligation, or both.
