| 1 | Recent advances in the surgical treatment of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the most common primary liver malignancy. The treatment of HCC is complex and complicated by the severity of associated chronic liver disease, the stage of HCC, and the clinical condition of the patient. Liver resection(LR) is one of the most efficient treatments for patients with HCC, with an expected 5-year survival of 38%-61% depending on the stage of the disease. Improved liver function assessment, increased understanding of segmental liver anatomy from advanced imaging studies, and surgical technical progress are important factors that have led to reduced mortality in patients with HCC. The indication for LR may be expanded due to emerging evidences from laparoscopic hepatectomies and combined treatments with newly developed chemotherapies. Liver transplantation(LT) is considered as an ideal treatment for removal of existing tumors and the injured/preneoplastic underlying liver tissue with impaired liver function and the risk of multicentric carcinogenesis that results from chronically injured liver. However, LT is restricted to patients with minimal risk of tumor recurrence under immunosuppression. The expansion of criteria for LT in HCC patients is still under trial and discussion. Limited availability of grafts, as well as the risk and the cost of transplantation have led to considerable interest in expansion of the donor pool, living donor-related transplantation, and combined treatment involving LR and LT. This highlight presents evidence concerning recent studies evaluating LR and LT in HCC patients. In addition, alternative therapies for the treatment of early stage tumors and the management of patients on transplant waiting lists are discussed. | Zenichi Morise Norihiko Kawabe Hirokazu Tomishige Hidetoshi Nagata Jin Kawase Satoshi Arakawa Rie Yoshida Masashi Isetani | 2014 | World Journal of Gastroenterology2014，20，39： | 24 |
| 2 | Pure laparoscopic hepatectomy for hepatocellular carcinoma with chronic liver disease显示文摘Pure laparoscopic hepatectomy is a less invasive procedure than conventional open hepatectomy for the resection of hepatic lesions. Increases in experiences with the technique, in combination with advances in technology, have promoted the popularity of pure laparoscopic hepatectomy. However, indications for usage and potential contraindications of the procedure remain unresolved. The characteristics and specific advantages of the procedure, especially for hepatocellular carcinoma(HCC) patients with chronic liver diseases,are reviewed and discussed in this paper. For cirrhotic patients with liver tumors, pure laparoscopic hepatectomy minimizes destruction of the collateral blood and lymphatic flow from laparotomy and mobilization, and mesenchymal injury from compression. Therefore, pure laparoscopic hepatectomy has the specific advantage of minimal postoperative ascites production that leads to lowering the risk of disturbance in water or electrolyte balance and hypoproteinemia. It minimizes complications that routinely trigger postoperative serious liver failure. Under adequate patient positioning and port arrangement, the partial resection of the liver in the area of subphrenic space, peri-inferior vena cava area or next to the attachment of retro-peritoneum is facilitated in pure laparoscopic surgery by providing good vision and manipulation in the small operative field.Furthermore, the features of reduced post-operative adhesion, good vision, and manipulation within the small area between the adhesions make this procedure safer in the context of repeat hepatectomy procedures.These improved features are especially advantageous for patients with liver cirrhosis and multicentric and/or metachronous HCCs. | Zenichi Morise Norihiko Kawabe Jin Kawase Hirokazu Tomishige Hidetoshi Nagata Hisanori Ohshima Satoshi Arakawa Rie Yoshida Masashi Isetani | 2013 | World Journal of Hepatology2013，5，9： | 21 |
| 3 | Laparoscopic liver resection for posterosuperior tumors using caudal approach and postural changes: A new technical approach显示文摘Laparoscopic liver resection(LLR) for tumors in the posterosuperior liver [segment(S) 7 and deep S6] is a challenging clinical procedure. This area is located in the bottom of the small subphrenic space(rib cage), with the large and heavy right liver on it when the patient is in the supine position. Thus, LLR of this area is technically demanding because of the handling of the right liver which is necessary to obtain a fine surgical view, secure hemostasis and conduct the resection so as to achieve an appropriate surgical margin in the cage. Handling of the right liver may be performed by the hand-assisted approach, robotic liver resection or by using spacers, such as a sterile glove pouch. In addition, the operative field of posterosuperior resection is in the deep bottom area of the subphrenic cage, with the liver S6 obstructing the laparoscopic caudal view of lesions. The use of intercostal ports facilitates the direct lateral approach into the cage and to the target area, with the combination of mobilization of the liver. Postural changes during the LLR procedure have also been reported to facilitate the LLR for this area, such as left lateral positioning for posterior sectionectomy and semi-prone positioning for tumors in the posterosuperior segments. In our hospital, LLR procedures for posterosuperior tumors are performed via the caudal approach with postural changes. The left lateral position is used for posterior sectionectomy and the semi-prone position is used for S7 segmentectomy and partial resections of S7 and deep S6 without combined intercostal ports insertion. Although the movement of instruments is restricted in the caudal approach, compared to the lateral approach, port placement in the para-vertebra area makes the manipulation feasible and stable, with minimum damage to the environment around the liver. | Zenichi Morise | 2016 | World Journal of Gastroenterology2016，22，47： | 20 |
| 4 | First quarter century of laparoscopic liver resection显示文摘The beginnings of laparoscopic liver resection(LLR)were at the start of the 1990s,with the initial reports being published in 1991 and 1992.These were followed by reports of left lateral sectionectomy in 1996.In the years following,the procedures of LLR were expanded to hemi-hepatectomy,sectionectomy,segmentectomy and partial resection of posterosuperior segments,as well as the parenchymal preserving limited anatomical resection and modified anatomical(extended and/or combining limited)resection procedures.This expanded range of LLR procedures,mimicking the expansion of open liver resection in the past,was related to advances in both technology(instrumentation)and technical skill with conceptual changes.During this period of remarkable development,two international consensus conferences were held(2008 in Louisville,KY,United States,and 2014 in Morioka,Japan),providing up-to-date summarizations of the status and perspective of LLR.The advantages of LLR have become clear,and include reduced intraoperative bleeding,shorter hospital stay,and-especially for cirrhotic patients-lower incidence of complications(e.g.,postoperative ascites and liver failure).In this paper,we review and discuss the developments of LLR in operative procedures(extent and style of liver resections)during the first quarter century since its inception,from the aspect of relationships with technological/technical developments with conceptual changes. | Zenichi Morise Go Wakabayashi | 2017 | World Journal of Gastroenterology2017，23，20： | 16 |
| 5 | Pure laparoscopic hepatectomy as repeat surgery and repeat hepatectomy显示文摘AIM:To assess clinical outcomes of laparoscopic hepatectomy(LH) in patients with a history of upper abdominal surgery and repeat hepatectomy.METHODS:This study compared the perioperative courses of patients receiving LH at our institution that had or had not previously undergone upper abdominal surgery.Of the 80 patients who underwent LH,22 had prior abdominal surgeries,including hepatectomy(n = 12),pancreatectomy(n = 3),cholecystectomy and common bile duct excision(n = 1),splenectomy(n = 1),total gastrectomy(n = 1),colectomy with the involvement of transverse colon(n = 3),and extended hysterectomy with extensive lymph-node dissection up to the upper abdomen(n = 1).Clinical indicators including operating time,blood loss,hospital stay,and morbidity were compared among the groups.RESULTS:Eighteen of the 22 patients who had undergone previous surgery had severe adhesions in the area around the liver.However,there were no conversions to laparotomy in this group.In the 58 patients without a history of upper abdominal surgery,the median operative time was 301 min and blood loss was 150 m L.In patients with upper abdominal surgical history or repeat hepatectomy,the operative times were 351 and 301 min,and blood loss was 100 and 50 m L,respectively.The median postoperative stay was 17,13 and 12 d for patients with no history of upper abdominal surgery,patients with a history,and patients with repeat hepatectomy,respectively.There were five cases with complications in the group with no surgical history,compared to only one case in the group with a prior history.There were no statistically significant differences in the perioperative results between the groups with and without upper abdominal surgical history,or with repeat hepatectomy.CONCLUSION:LH is feasible and safe in patients with a history of upper abdominal surgery or repeat hepatectomy. | Masashi Isetani Zenichi Morise Norihiko Kawabe Hirokazu Tomishige Hidetoshi Nagata Jin Kawase Satoshi Arakawa | 2015 | World Journal of Gastroenterology2015，21，3： | 13 |
| 6 | Caudal approach to pure laparoscopic posterior sectionectomy under the laparoscopy-specific view显示文摘AIM:To study our novel caudal approach laparoscopic posterior-sectionectomy with parenchymal transection prior to mobilization under laparoscopy-specific view.METHODS:Points of the procedure are:(1) Patients are put in left lateral position and posterior sector is not mobilized;(2) Glissonian pedicle of the sector is encircled and clamped extra-hepatically and divided afterward during the transection;(3) Dissection of inferior vena cava(IVC) anterior wall behind the liver is started from caudal.Simultaneously,liver transection is performed to search right hepatic vein(RHV) from caudal;(4) Liver transection proceeds to the bifurcation of the vessels from caudal to cranial,exposing the surfaces of IVC and RHV.Since the remnant liver sinks down,the cutting surface is well-opend;and(5) After the completion of transection,dissection of the resected liver from retroperitoneum is easily performed using the gravity.This approach was performed for a 63 years old woman with liver metastasis close to RHV.RESULTS:RHV exposure is required for R0 resection of the lesion.Although the cutting plane is horizontal in supine position and the gravity obstructs the exposure in the small subphrenic space,the use of specific characteristics of laparoscopic hepatectomy,such as the good vision for the dorsal part of the liver and IVC and facilitated dissection using the gravity with the patient positioning,made the complete RHV exposure during the liver transection easy to perform.The operation time was 341 min and operative blood loss was 1356 mL.Her postoperative hospital stay was uneventfull and she is well without any signs of recurrences 14 mo after surgery.CONCLUSION:The new procedure is feasible and useful for the patients with tumors close to RHV and the need of the exposure of RHV. | Hirokazu Tomishige Zenichi Morise Norihiko Kawabe Hidetoshi Nagata Hisanori Ohshima Jin Kawase Satoshi Arakawa Rie Yoshida Masashi Isetani | 2013 | World Journal of Gastrointestinal Surgery2013，5，6： | 7 |
| 7 | Surgery and chemotherapy for intrahepatic cholangiocarcinoma显示文摘Cholangiocarcinoma, arising from bile duct epithelium, is categorized into intrahepatic cholangiocarcinoma (ICC) and extrahepatic cholangiocarcinoma (ECC), including hilarcholangiocarcinoma. Recently, there has been a worldwide increase in the incidence and mortality from ICC. Complete surgical resection is the only approach to cure the patients with ICC. However, locoregional extension of these tumors is usually advanced with intrahepatic and lymph-node metastases at the time of diagnosis. Resectability rates are quite low and variable (18%-70%). The five-year survival rate after surgical resection was reported to be 20%-40%. Median survival time after ICC resection was 12-37.4 mo. Only a small number of ICC cases, accompanied with ECC, gall bladder carcinoma, and ampullary carcinoma, have been reported in the studies of chemotherapy due to the rarity of the disease. However, in some reports, significant anti-cancer effects were achieved with a response rate of up to 40% and a median survival ofone year. Although recurrence rate after hepatectomy is high for the patients with ICC, the residual liver and the lung are the main sites of recurrence after tentative curative surgical resection. Several patients in our study had a long-term survival with repeated surgery and chemotherapy. Repeated surgery, combined with new effective regimens of chemotherapy, could benef it the survival of ICC patients. | Zenichi Morise Atsushi Sugioka Takamasa Tokoro Yoshinao Tanahashi Yasuhiro Okabe Tadashi Kagawa Chinatsu Takeura | 2010 | World Journal of Hepatology2010，2，2： | 4 |
| 8 | Perspective of laparoscopic liver resection for hepatocellular carcinoma显示文摘Liver resection(LR) for hepatocellular carcinoma(HCC) in patients with chronic liver disease(CLD) is associated with high risks of developing significant postoperative complications and multicentric metachronous lesions, which can result in the need for repeated treatments. Studies comparing laparoscopic procedures to open LR consistently report reduced blood loss and transfusionsrequirements, lower postoperative morbidity, and shorter hospital stays, with no differences in oncologic outcomes. In addition, laparoscopic LR is associated with reduced postoperative ascites and a lower incidence of liver failure for HCC patients with CLD, due to the reduced surgery-induced parenchymal injury to the residual liver and limited destruction of the collateral blood/lymphatic flow around the liver. Finally, this procedure facilitates subsequent repeat LR due to minimal adhesion formation and improved vision/manipulation between adhesions. These characteristics of laparoscopic LR may lead to an expansion of the indications for LR. This editorial is based on the review and meta-analysis presented at the 2nd International Consensus Conference on Laparoscopic Liver Resection in Iwate, Japan, in October 2014(Chairperson of the congress is Professor Go Wakabayashi from the Department of Surgery, Iwate Medical University School of Medicine), which is published in the Journal of Hepato-Biliary-Pancreatic Sciences. | Zenichi Morise | 2015 | World Journal of Gastrointestinal Surgery2015，7，7： | 3 |
| 9 | Azathioprine is essential following cyclosporine for patients with steroid-refractory ulcerative colitis显示文摘AIM: To evaluate long-term prognosis following cyclosporine treatment by examining the rate of surgery avoidance among cyclosporine responders.METHODS: We retrospectively reviewed clinical records for 29 patients diagnosed with severe steroid-refractory ulcerative colitis in our hospital from August 1997 to August 2008 and treated with cyclosporine by continuous intravenous infusion.All patients were treated with intravenous corticosteroids for more than 5 d prior to cyclosporine therapy.Administration was continued for up to 21 d under serum monitoring to maintain cyclosporine levels between 400 and 600 ng/mL.Clinical activity was assessed before and after cyclosporine therapy using the clinical activity index score,with a reduction of ≥ 5 considered to indicate a response.Among responders,we defined cases not requiring surgery for more than 5 years as exhibiting long-term efficacy of cyclosporine.Factors considered to be possibly predictive of long-term efficacy of cyclosporine were sex,age,disease duration,clinical activity index score,C-reactive protein level,hemoglobin level,disease extent,endoscopic findings,and clinical course.RESULTS: Cyclosporine was not discontinued due to side effects in any patient.Nineteen(65.5%) of 29 patients were considered responders.A statistically significant(P = 0.004) inverseas sociation wa s observed between an endoscopic finding of 'mucosal bleeding' and responsive cases.Fifteen(9 males,6 females) of these 19 patients were followed for 5 years or more,of whom 9(60%) exhibited long-termefficacy of cyclosporine.Of the 10 non-responders,9(90%) underwent surgery within 6 mo of cyclosporine therapy.None of the following factors had a significant impact on the long-term efficacy of cyclosporine: sex,age,duration of disease,clinical activity index score,C-reactive protein level,hemoglobin level,extent of disease,endoscopic findings,or clinical course.In contrast,a significant association was observed for maintenance therapy with azathioprine after cyclosporine therapy(P = 0.0014).CONCLUSION: Maintenance therapy with azathioprine might improve the long-term efficacy of continuously infused cyclosporine for severe steroid-refractory ulcerative colitis patients. | Nobuyuki Miyake Takafumi Ando Kazuhiro Ishiguro Osamu Maeda Osamu Watanabe Yutaka Hirayama Keiko Maeda Kazuhiro Morise Masanobu Matsushita Kazuhiro Furukawa Kohei Funasaka Masanao Nakamura Ryoji Miyahara Naoki Ohmiya Hidemi Goto | 2015 | World Journal of Gastroenterology2015，21，1： | 3 |
| 10 | Clinical utility of a new endoscopic scoring system for Crohn's disease显示文摘AIM:To evaluate the clinical value of the newly modified Simple Endoscopic Score for Crohn's disease(m SES-CD).METHODS:Seventy-six Crohn's disease(CD) patients who underwent transanal double balloon endoscopy(DBE) in our hospital between 2003 and 2012 were retrospectively reviewed. DBE is defined as small intestinal endoscopy using two attached balloons. We included patients with stenosis which hampered passage of the scope and those who underwent DBE with observation for at least 80 cm from the ileocecal valve. Our new m SES-CD assesses the endoscopic activity of two consecutive small intestinal segments located 0-40 cm and 40-80 cm from the ileocecal valve by DBE,in addition to the activity of four colorectal segments. To compare the usefulness of m SES-CD with SES-CD,we similarly divided the patients into two groups according to total m SES-CD score(low disease activity group,< 4; high disease activity group,≥ 4). The clinical value of m SES-CD in predicting clinical outcome in patients with CD was evaluated using the occurrence of surgery after DBE as an endpoint.RESULTS:Median age of the 76 CD patients was 36 years(range,16-71). Thirty-nine patients had stenosis which hampered passage of the DBE to 80 cm on the proximal side from the ileocecal valve. Median evaluable length of small intestine by DBE was 80 cm(range,3-200). A total of 74 patients had one or more small intestinal lesions detected by DBE,of which 62(83.8%) were within 80 cm of the ileocecal valve on the proximal side. Only two patients(2.7%) with proximal-side lesions more than 80 cm from the ileocecal valve did not have lesions within 80 cm. Patients with high m SES-CD scores showed significantly shorter surgeryfree survival than those with low scores(P < 0.05). In contrast,surgery-free survival did not significantly differ between the low and high SES-CD groups(P > 0.05). Multivariate analysis by a Cox proportional hazards model identified m SES-CD as an independent factor for surgery-free survival.CONCLUSION:m SES-CD is useful in evaluating the risk of surgery-free survival in patients with CD. | Kazuhiro Morise Takafumi Ando Osamu Watanabe Masanao Nakamura Ryoji Miyahara Osamu Maeda Kazuhiro Ishiguro Yoshiki Hirooka Hidemi Goto | 2015 | World Journal of Gastroenterology2015，21，34： | 2 |
