RESUMEN
We present a case of a 44-year-old woman with rectal cancer(cT2N3M0, cStage â ¢b)treated with 4 capecitabine-oxaliplatin( CAPOX)therapy courses, followed by laparoscopic intersphincteric resection. The patient received 7 postoperative, adjuvant CAPOX therapy courses. After 16 months since the final CAPOX administration, computed tomography(CT) revealed multiple liver tumors, showing early enhancement, and a jejunal mesenteric mass suspected to be a gastrointestinal stromal tumor(GIST). To overcome the percutaneous needle biopsy limitation, laparoscopic partial hepatectomy and laparoscopic- assisted partial intestinal resection were performed. Two liver lesions were diagnosed as nodular regenerative hyperplasia( NRH)with sinusoidal obstruction syndrome(SOS), supported by the hyperplasia and sinusoidal dilatation pathological findings, consequential to using oxaliplatin. Considering the rarity of NRH, using oxaliplatin may be proven vital in the differential diagnosis.

Among portosystemic shunts, splenorenal shunts can cause increased portal pressure, which in turn can bring about hyperammonemia, resulting in hepatic encephalopathy. In recent years, it has been reported that oxaliplatin(OX), a key chemotherapy drug in colorectal cancer, can precipitate splenorenal shunts due to sinusoidal injury. We report a case of hyperammonemia post oxaliplatin therapy. A 72-year-old male patient who had undergone surgical resection for(RS)rectal cancer with hepatic metastasis had been receiving capecitabine plus OX(CAPOX)as adjuvant chemotherapy. During his 7th course of treatment, he visited the outpatient clinic with complaints of weakness, dysarthria, and urinary incontinence. Laboratory findings showed an elevated NH3 level (200 µg/dL), and subsequent abdominal computed tomography revealed a splenorenal shunt, which was attributed to OX. Balloon-occluded retrograde transvenous obliteration(BRTO)was then performed. The patient has been routinely followed up in the outpatient clinic and has had no recurrence of hyperammonemia or cancer 14 months after the procedure. In retrospect, the splenorenal shunt was present on his first visit, therefore, hyperammonemia could have been prevented at the time of commencement of chemotherapy. We report our case, along with the relevant literature.

BACKGROUND: Repeat hepatectomy is an acceptable treatment for recurrent hepatocellular carcinoma (HCC). However, repeat laparoscopic liver resection (LLR) has not been widely adopted due to its technical difficulty. This study aimed to assess the feasibility and efficacy of repeat LLR compared with repeat open liver resection (OLR) for recurrent HCC. METHODS: We performed 42 repeat OLR and 30 repeat LLR for cases of recurrent HCC between January 2007 and March 2018. This study retrospectively compared the patients' clinicopathological characteristics and operative and short-term outcomes including surgical time, intraoperative blood loss, duration of hospital stay, and postoperative complications between the two groups. RESULTS: There were no significant differences in patient characteristics between the two groups except in terms of Child-Pugh grade. The repeat LLR group had lower median intraoperative blood loss (100 mL vs. 435 mL; P = 0.001) and shorter median postoperative hospital stay (10 days vs. 14.5 days; P = 0.002). The other results including postoperative complications were comparable between the two groups. Further, comparison of two subpopulations of the repeat LLR group stratified by previous hepatectomy type (open or laparoscopic) or tumor location (segments 7 and 8 or other) revealed no significant differences in the postoperative clinical characteristics between them, although the morbidity rate tended to be higher in patients who underwent open hepatectomy for primary HCC than in patients who underwent laparoscopic hepatectomy. CONCLUSIONS: Repeat LLR for recurrent HCC is feasible and useful with good short-term outcomes although an appropriate patient selection seems to be necessary.

BACKGROUND: Repeat liver resection is an effective treatment approach for patients with recurrent hepatocellular cell carcinoma (HCC). However, the surgical feasibility and oncological significance of repeat laparoscopic liver resection (r-LLR) remain unproven. This study evaluates and compares the clinical outcomes of non-anatomic r-LLR applied towards recurrent HCC, with those of primary LLR (p-LLR) for primary HCC. METHODS: This retrospective study reports 104 patients with HCC, treated with LLR between 2014 and 2018. Twenty eight of these patients underwent r-LLR for recurrent HCC. The clinical and surgical variables were reviewed for all cases. RESULTS: The analysis was limited to non-anatomic resection across both groups (r-LLR: 89% (25/28) vs. p-LLR: 80% (61/76)). There were no statistically significant differences about patient background between the two groups, with the exception of Child-Pugh classification. r-LLR surgical techniques included single-site laparoscopic adhesiolysis (32%, 8/25), Pringle maneuver (8%, 2/25), and crush-clamp method using BiClamp for hepatic parenchymal transection (72%, 18/25). No severe postoperative complications were observed in the r-LLR group. Postoperative hospital stays and procedure-related postoperative survival were similar for both groups. CONCLUSIONS: Non-anatomical r-LLR renders comparable surgical and oncological outcomes. Our data suggest that non-anatomical r-LLR is a safe and feasible therapeutic approach to recurrent HCC.

We herein report a case of cecum cancer with synchronous adrenal solitary metastasis. A 62-year-old woman who had been treated for other disease complained of weight loss. Lower endoscopy revealed cecum cancer, and computed tomography( CT)demonstrated a solitary left adrenal tumor; thus, she was diagnosed with a metastatic tumor. We concluded that the patient was a possible candidate for surgical resection because she did not present with local metastasis other than in the adrenal glands. Ileocecal resection and left adrenalectomy were performed. The histological findings indicated moderately differentiated adenocarcinoma, which was compatible with cecum cancer. The patient was administered chemotherapy containing mFOLFOX6, and no recurrence has been detected 4 years after the surgery. Some patients who develop solitary adrenal metastasis from colonic cancer appear to be good candidates for surgery in anticipation of a good prognosis.

We report a case of pneumonectomy followed by radical pancreatectomy after oral administration of TS-1 for pancreatic cancer with complications ofa lung tumor. The patient was a 66-year-old woman. A pancreatic tail tumor and 2 lung nodules were detected on CT scans, and were diagnosed as pancreatic cancer and metastatic lung cancer. During a total of1 1 courses ofTS -1 therapy, the pancreatic tumor tended to contract, but both pulmonary nodules remained unchanged. Due to differences in treatment effect, double cancers of the lung and pancreas were suspected, rather than metastatic lung cancers. We performed a VATS partial resection of the left lower lobe for diagnostic therapy. The pathological diagnosis revealed an inflammatory myofibroblastic tumor and a primary lung cancer. We diagnosed that a radical pancreatectomy was possible and performed distal pancreatectomy. Pathological diagnosis confirmed an invasive pancreatic ductal carcinoma. Oral administration ofTS -1 was performed as adjuvant chemotherapy after surgery. Liver metastasis was observed 10 months after pancreatectomy, and GEM therapy was initiated. Peritoneal dissemination was observed at 2 years following pancreatectomy, and the patient died at 2 years and 9 months. TS-1 therapy for synchronous lung tumors and pancreatic cancer with careful observation allowed for a definitive radical resection. This method was an effective treatment for lung nodules with pancreatic cancer.

Myxofibrosarcoma(MFS)is one of the most common sarcomas in the extremities of elderly patients.We report a rare case of MFS originating in the retroperitoneum.A 65-year-old man presented to our hospital with an intraabdominal tumor, which was identified by abdominal CT during an investigation of an abdominal protuberance.Contrast -enhanced CT and MRI revealed a 18×12 cm mass in the left retroperitoneum.The patient underwent retroperitoneum tumor resection.Operative findings showed that there was an indistinct area between the left side of the tumor and the abdominal wall.There was no residual tumor macroscopically after the operation.The histopathological diagnosis was MFS arising from the retroperitoneum. Four months later, local recurrence and para-aortic lymph node metastasis were diagnosed.We performed tumor resection; however, the recurrent tumor had invaded the iliopsoas and iliac muscles.Additionally, there was peritoneal dissemination around the tumor.Five months after the initial surgery, a recurrence on the back was identified.He died 7 months after the first operation.According to previous reports, patients who undergo an operation with pathologically negative margins achieve better surgical outcomes.Therefore, it is important to perform expanded resection with enough surgical margin as possible.

A 65-year-old woman had received chemotherapy for malignant lymphoma since 2011. After the 8th course, computed tomography revealed the disappearance of lymph node metastasis, except for 22mm of the mass located on the tail side of the antrum. MRI showed a low intensity mass on the T1 and T2-weighted images. FDG-PET did not show abnormal uptake in the tumor. EUS-FNA did not reveal a definitive diagnosis. We performed a laparotomy for diagnosis and treatment. Intraoperative findings showed that the tumor occurred in the mesentery of the transverse colon. The pathological diagnosis was angiomyolipoma. The patient has been free from recurrent disease for 2 years and 6 months. Angiomyolipoma originating in the transverse mesentery region is rare and, due to various percentage of tissue factors, there are no fixed view of image findings. Furthermore, a large tissue volume is need for histological diagnosis. Laparotomy is useful for diagnosis and therapy for angiomyolipoma occurring in the mesentery of the transverse colon.

A 67-year-old woman, who was diagnosed with ovarian cancer with multiple metastases, underwent abdominal total hysterectomy, bilateral salpingo-oophorectomy, para-aortic lymph node dissection(b2), omental subtotal hysterectomy, and lower anterior rectal resection after receiving a combination of PTX plus CBDCA chemotherapy. Macroscopically, complete resection was achieved and histopathological examination of the resectedspecimen showedpoorly differentiatedserous adenocarcinoma. After surgery, additional chemotherapy was administered. However, increasing only lesser curvature of stomach lymph node, we performed laparoscopic lymph node resection as debulking surgery. It is often said that macroscopic complete resection of ovarian cancer improves the prognosis. In particular, we hope that this patient will survive longer with a sustainable quality of life as a result of laparoscopic stomach- andnerve -sparing surgery.

Previously, we detected B cells expressing receptors for blood group A carbohydrates in the CD11b(+)CD5(+) B-1a subpopulation in mice, similar to that in blood group O or B in humans. In the present study, we demonstrate that CD1d-restricted natural killer T (NKT) cells are required to produce anti-A antibodies (Abs), probably through collaboration with B-1a cells. After immunization of wild-type (WT) mice with human blood group A red blood cells (A-RBCs), interleukin (IL)-5 exclusively and transiently increased and the anti-A Abs were elevated in sera. However, these reactions were not observed in CD1d(-/-) mice, which lack NKT cells. Administration of anti-mouse CD1d blocking monoclonal Abs (mAb) prior to immunization abolished IL-5 production by NKT cells and anti-A Ab production in WT mice. Administration of anti-IL-5 neutralizing mAb also diminished anti-A Ab production in WT mice, suggesting that IL-5 secreted from NKT cells critically regulates anti-A Ab production by B-1a cells. In nonobese diabetic/severe combined immunodeficient (NOD/SCID/γc(null)) mice, into which peripheral blood mononuclear cells from type O human volunteers were engrafted, administration of anti-human CD1d mAb prior to A-RBC immunization completely inhibited anti-A Ab production. Thus, anti-CD1d treatment might constitute a novel approach that could help in evading Ab-mediated rejection in ABO-incompatible transplant recipients.

Hepatopulmonary syndrome (HPS) is a severe complication in patients with chronic liver disease with poor prognosis. Liver transplantation (LT) is a promising treatment for HPS; however, very severe HPS, which is defined by an arterial oxygen pressure (PaO2 ) of less than 50 mmHg and a right-left intrapulmonary shunt rate of more than 20%, may be a contraindication to LT, including living donor LT (LDLT). Here, we report two cases of decompensated liver cirrhosis with very severe HPS which were resolved after adult-to-adult LDLT including ABO-incompatible LDLT. Both patients required oxygen supportive therapy in combination with specialized respiratory care postoperatively, followed by improvement of oxygenation and substantial decreases of intrapulmonary shunt rate. These findings suggest very severe HPS can be resolved by LDLT, including ABO-incompatible LDLT, and reduced graft volume did not impede the reversal of intrapulmonary shunting. Our current report may indicate that adult-to-adult LDLT, including ABO-incompatible LDLT, is becoming an effective therapeutic method and prompt a review of previous reports as well as our own files with particular regard to the indication of LDLT for decompensated liver cirrhosis with very severe HPS.
RESUMEN
The aim of this study was to compare the efficacy of self-expandable metallic stent (SEMS) and transanal tube as preoperative treatments for left-sided obstructive colon cancer. Forty-three patients (the SEMS group: 28 cases, the tube group: 15 cases) were included in this study. Clinicopathological data (age, sex, tumor location, depth, histological type, stage) were comparable between the 2 groups. In addition, there was no difference in intestinal decompression rate between the SEMS group and the tube group (technical success rate: 100% vs 86.7%, clinical success rate: 92.8% vs 73.3%, complication rate: 7.1% vs 0%). A significantly higher number of patients in the SEMS group underwent laparoscopic surgery because of difference of historical background. However, no significant difference was observed between the 2 groups in postoperative outcome(complication rate, hospital stay duration). SEMS insertion had several benefits compared to transanal tube placement, such as the resumption of oral intake because of rapid resolution of obstruction and easier management because SEMSs do not require washing. SEMS insertion could be a safe and effective bridge to subsequent surgery in patients with left-sided obstructive colon cancer.

We report a case of radical resection of rectal cancer with multiple liver and lung metastases after preoperative chemotherapy. A 54-year-old woman presented with abdominal pain and loss of body weight due to rectal cancer with multiple liver and lung metastases. Therefore, the patient received 14 courses of bevacizumab+mFOLFOX6, and 7 courses of panitumumab+FOLFIRI. After the chemotherapy, the size of the distant metastases reduced by 62% on computed tomography, according to RECIST. Due to the reduction in size, a conversion surgery was attempted. First, an abdominal operation with laparoscopy was performed, and 2 months later an operation to resect the lung metastases via thoracoscopy was performed. Currently, 3 months after surgery, the patient is alive, without recurrence.

A 70-year-old woman who complained of abdominal pain and a prolapsed tumor from the anus was diagnosed with an intestinal obstruction resulting from anal canal cancer. Computed tomography (CT) and magnetic resonance imaging revealed a huge tumor (11×5×12 cm) invading the vagina and levator ani muscle. Enlarged inguinal lymph nodes on both sides indicated metastasis. The clinical stage was T4b (vagina, levator ani muscle, and pudenda) N0H0M1a (LYM), stage IV (Japanese Classification of Colorectal Carcinoma: 8th edition). As curative resection was not possible, a transvers colostomy was performed to relieve the intestinal obstruction. This was followed by chemoradiotherapy (45 Gy/1.8 Gy×25; TS-1, 80 mg/body for 2 weeks and a 1-week interval, for 2 courses) and up to 10 courses of Bev+mFOLFOX6 continuously. After this regimen, there was a remarkable reduction in tumor size. Positron emission tomography-CT revealed no FDG uptake in the primary rectal site or inguinal lymph nodes, but a maximum standardized uptake value (SUVmax) of 6.3 was detected in the vagina. Six weeks after chemotherapy, the patient underwent a pelvic exenteration including resection of the vagina, bladder, and pudenda. The pathological stage was yp T4b (vagina) N0H0M0, stageâ ¡. Curative resection was performed, and the patient had a Grade 2 pathological response after chemoradiotherapy.

We report a case of small intestinal adenocarcinoma treated with laparoscopic surgery. A 70-year-old woman had abdominal pain and epigastralgia. There were no abnormal findings on upper and lower endoscopy. The symptoms continued for 4 months after endoscopy, so she presented to our hospital. After CT examination, small bowel cancer with ileus was suspected. An ileus tube was inserted to relieve the bowel pressure and she was diagnosed with ileum cancer by enteroscopy. Laparoscopic surgery was performed and the pathological stage was determined as pStage â ¢a. She was treated with oral chemotherapy (UFT plus LV) and had no recurrence 6 months after surgery.

A 77-year-old-woman, whose chief complaint was anemia, was referred to our hospital and diagnosed with advanced gastric cancer with liver metastasis and lymph node metastasis.Gastrointestinal endoscopy showed a tumor on the lesser curvature of the gastric corpus.Histologically, biopsy specimens indicated adenocarcinoma with genetic amplification of human epidermal growth factor receptor type 2.Computed tomography and magnetic resonance imaging showed lymph node metastasis and liver metastasis.The patient received a total gastrectomy and a partial liver resection after combination chemotherapy consisting of capecitabine, cisplatin, and trastuzumab.Histopathological examination of a resected specimen showed a minute residual cancer nest at the subserosa of the stomach and lymph node metastasis, but no liver metastasis. This combined modality therapy can be considered an effective treatment for gastric cancer with liver metastasis, and we hope that it will be established as a standard therapy.

The purpose of this study was to evaluate the diagnostic capability of gadoxetate disodium (Gd-EOB)-MRI for the detection of hepatocellular carcinoma (HCC) compared with multidetector CT (MDCT). Fifty patients with 57 surgically proven HCCs who underwent Gd-EOB-MRI and MDCT from March 2008 to June 2011 were evaluated. Two observers evaluated MR and CT on a lesion-by-lesion basis. We analyzed sensitivity by grading on a 5-point scale, the degree of arterial enhancement and the differences in histological grades in the diffusion-weighted images (DWI). The results showed that the sensitivity of Gd-EOB-MRI was higher than that of MDCT especially for HCCs that were 1 cm in diameter or smaller. The hepatobiliary phase was useful for the detecting of small HCC. We had few cases in which it was difficult to judge HCC in the arterial enhancement between MRI and MDCT. In the diffusion-weighted image, well differentiated HCC tended to show a low signal intensity, and poorly differentiated HCC tended to show a high signal intensity. In moderately differentiated HCC's, the mean diameter of the high signal intensity group was larger than that of the low signal intensity group (24.5 mm vs. 15.8 mm). In conclusion, Gd-EOB-MRI tended to show higher sensitivity compared to MDCT in the detection of HCC.

A 58-year-old man was admitted to the author's institution with complaints of dysphagia and tarry stool. An advanced squamous cell carcinoma of the esophagogastric junction was revealed by endoscopy. The clinical stage was GE, T4, N1, H0, M0, cStageIVa, according to the Japanese Classification of Esophageal Cancer. Low-dose FP chemotherapy(continuous 5-FU div of 500mg/day with intermittent CDDP div of 10mg/day)was used. The tumor size was remarkably reduced while the side effects were trivial. A clinically complete response was recognized with CT and with pathological findings from endoscopic biopsy. As a recurrence was diagnosed in the off-treatment period, the same regimen was resumed. Soon, a complete response was again. The patient is doing well with no reoccurrence after almost 10 years, with a low-dose FP chemotherapy.

BACKGROUND: The strategy for treating extremely aged patients with gastric carcinoma is controversial. This study reviews the prognoses of patients aged 85 years and older who were diagnosed with gastric carcinoma. METHODS: One hundred seventeen patients aged 85 years and older were diagnosed as having gastric carcinoma after 1969 in our institution. After excluding those at stage IV, 36 cases underwent curative resection and 30 cases received best supportive care (BSC), which we reviewed retrospectively. RESULTS: Surgical methods included distal gastrectomy for 28 cases, total gastrectomy for five cases, and other procedures for three cases. Postoperatively, pneumonia developed in four cases, anastomotic leakage in two cases, and pancreatic fistula in one case. Two patients died of pneumonia within 1 month of surgery. Univariate analysis demonstrated that age, surgery, performance status, and sodium level were statistically significant prognostic factors. Multivariate analysis demonstrated that surgery was the only independent prognostic factor. When patients with a performance status of 4 were excluded, the clinical characteristics of the surgery group (n = 36) and BSC group (n = 20) were statistically identical, and the overall survival was significantly better in the surgery group (p = 0.0078). CONCLUSIONS: Postoperative outcomes were relatively acceptable. Surgery may be feasible and beneficial even for extremely aged patients 85 years and older, except for those with a performance status of 4.

Interferon (IFN) therapy with or without ribavirin treatment is well established as a standard antiviral treatment for hepatitis C virus (HCV)-infected patients. However, susceptibility to thrombocytopenia is a major obstacle for initiating or continuing this therapy, particularly in liver transplant (LTx) recipients with HCV. Studies have reported that splenectomy performed concurrently with LTx is a feasible strategy for conditioning patients for anti-HCV IFN therapy. However, the relationship between the severity of splenomegaly and alterations in the blood cytopenia in LTx recipients remains to be clarified. Here, we analyzed the relationship between spleen volume (SV) and thrombocytopenia in 45 patients who underwent LTx at Hiroshima University Hospital. The extent of pre-LTx splenomegaly [the SV to body surface area (BSA) ratio in an individual] was inversely correlated with both the post-LTx white blood cell count and platelet (PLT) count (P < 0.001). Furthermore, the PLT count of patients with thrombocytopenia (PLT count
