Abstract
A 62-year-old woman underwent a subtotal stomach-preserving pancreatoduodenectomy for ampullary carcinoma (T3bN0M0, Stage Ⅱb). Histopathologically, the tumor was a tubular adenocarcinoma with mixed features, predominantly the intestinal type, following which adjuvant chemotherapy was not performed. Computed tomography performed 32 months after surgery showed a tumor measuring 6.7 mm in diameter at the apex of the right lung. The tumor had gradually increased in size and measured 10 mm in diameter, 47 months postoperatively. Since other metastatic lesions were absent, partial resection of the right lung under video-assisted thoracic surgery was performed 48 months postoperatively. Histopathological testing confirmed a diagnosis of lung metastasis from the resected specimen of ampullary carcinoma without mediastinal lymph node metastasis. Adjuvant chemotherapy was not performed, and recurrence was not observed even after 53 months following the partial lung resection. Previously, 7 resected cases of solitary lung metastasis from ampullary cancer have been reported. The histopathological sub-type of these 7 cases were intestinal type in 5 and pancreatobiliary type in 2 cases, respectively. No mortality or recurrence was observed for 8-119 months in any of the 7 cases(median, 19 months). In conclusion, owing to the good prognosis, solitary lung metastasis from an ampullary cancer can be classified as an oligometastatic disease, based on the concept proposed by Hellman and Weichselbaum.

Abstract
An 86-year-old man presented with upper abdominal pain and was diagnosed with type 0-Ⅲ gastric cancer located at the posterior wall of the upper stomach by upper gastrointestinal endoscopy. Laparoscopic total gastrectomy(D1+)was performed for gastric cancer of cStage Ⅰ. As final pathological diagnosis was pT2N0(0/27)M0H0P0CY0, pStage ⅠB, adjuvant chemotherapy was not administrated. The patient has been alive with no recurrence for 5 years after surgery. 8 years and 1 month after procedure, he visited our hospital with chief complaint of abdominal distention and anorexia. Chest and abdominal CT showed pleural fluid and ascites, but PET-CT could not detect any sites of recurrence. Cytopathology and cell blocks by immunohistochemical staining of ascites proved recurrence of previous gastric cancer. Any treatment was rejected, and the patient died 3 months after recurrence and 8 years and 4 months after gastrectomy. Late recurrence on both pleura and peritoneum of gastric cancer is very rare. We report a case of pStage ⅠB gastric cancer relapsed on both pleura and peritoneum 8 year after radical gastrectomy.

Abstract
A 67-year-old man was introduced to examine for abnormal findings in physical examination. Upper gastrointestinal endoscopy detected the 3 lesions and diagnosed multiple gastric cancers with biopsy. Laparoscopic total gastrectomy was performed and final pathological diagnosis was pT2N1M0, pStage ⅡA with HER2 positive(3+). Adjuvant chemotherapy was not administrated. CT findings 6 months after procedure showed 2 liver metastases(S6, S7)and laparoscopic partial liver resection was performed. Pathological findings proved the metastasis of previous gastric cancer. Although adjuvant chemotherapy of S-1 was started 2 months after hepatectomy, CT findings showed second recurrences in liver and right adrenal gland. Chemotherapy was changed to S-1 plus cisplatin(SP)plus trastuzumab. AS these recurrence sites and ascites could not be detected by CT after 6 courses, therapeutic effect was judged as clinical CR(cCR)and SP plus trastuzumab was stopped due to side effect. Since then, regular follow-up CT showed preservation of status of cCR without chemotherapy and he has been alive without recurrence for 8 years and 9 months after gastrectomy. We report a case of recurrent gastric cancer of multiple organ metastasis with long-term survival due to multimodal treatment.

Comparison of clinicopathological characteristics between resected ampullary carcinoma and carcinoma of the second portion of the duodenum. World J Gastrointest Surg 2022; 14:1219-1229. [PMID: 36504514 PMCID: PMC9727577 DOI: 10.4240/wjgs.v14.i11.1219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 10/10/2022] [Accepted: 10/20/2022] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Few studies compared the oncological and biological characteristics between ampullary carcinoma (AC) and cancer of the second portion of the duodenum (DC-II), although both tumors arise from anatomically close locations.
AIM To elucidate differences in clinicopathological characteristics, especially the patterns of lymph node metastasis (LNM), between AC and DC-II.
METHODS This was a retrospective cohort study of 80 patients with AC and 27 patients with DC-II who underwent pancreaticoduodenectomy between January 1998 and December 2018 in two institutions. Clinicopathological factors, LNM patterns, and prognosis were compared between the two groups.
RESULTS The patients with AC and DC-II did not exhibit significant differences in 5-year overall survival (66.0% and 67.1%, respectively) and 5-year relapse-free survival (63.5% and 62.2%, respectively). Compared to the patients with DC-II, the rate of preoperative biliary drainage was higher (P = 0.042) and the rates of digestive symptoms (P = 0.0158), ulcerative-type cancer (P < 0.0001), large tumor diameter (P < 0.0001), and advanced tumor stage (P = 0.0019) were lower in the patients with AC. The LNM rates were 27.5% and 40.7% in patients with AC and DC-II, respectively, without significant difference (P = 0.23). The rates of LNM to hepatic nodes (N-He) and pyloric nodes (N-Py) were significantly higher in patients with DC-II than in those with AC (metastasis to N-HE: 18.5% and 5% in patients with DC-II and AC, respectively; P = 0.0432; metastasis to N-Py: 11.1% and 0% in patients with DC-II and AC, respectively; P = 0.0186)
CONCLUSION Although there were no significant differences in the prognosis and recurrence rates between the two groups, metastases to N-He and N-Py were more frequent in patients with DC-II than in those with AC.

Mucinous cystic neoplasm of the liver with polypoid nodule prolapsing into the bile duct: a case report and review of literature. Surg Case Rep 2022; 8:177. [PMID: 36138328 PMCID: PMC9500141 DOI: 10.1186/s40792-022-01511-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 08/06/2022] [Indexed: 11/29/2022] Open
Abstract
Background Mucinous cystic neoplasm of the liver (MCN-L) is a rare cystic tumor as defined by the 2010 World Health Organization classification. MCN-L usually does not communicate with or grow into the bile duct. Herein, we present a rare case of MCN-L with a polypoid nodule protruding into the bile duct. Case presentation A 69-year-old woman was referred to our hospital for elevated serum liver enzyme levels and obstructive jaundice. The patient also complained of abdominal pain in the right hypochondriac region. Abdominal ultrasonography showed a cystic lesion in segment 4 (S4) of the liver. Computed tomography revealed a 4-cm multilocular cystic lesion with a thick wall and multiple septal formations, showing a cyst-in-cyst appearance in S4. Endoscopic retrograde cholangiography showed a contrast defect between the left hepatic duct and the common bile duct, which was suspected to be a nodular lesion in the bile duct. Bile cytology and biopsy of the nodular lesion showed no malignant findings. Based on these findings, the differential diagnosis in this patient included intraductal papillary neoplasm of the bile duct and MCN-L, which had malignant potential. The patient underwent left hemihepatectomy, including caudate lobe excision with bile duct resection and right hepatocholangiojejunostomy. Macroscopic findings showed a 40 × 29 mm multilocular cystic lesion with a polypoid nodule that protruded into the left intrahepatic bile duct. As an ovarian-like stroma was observed in both cystic and polypoid lesions microscopically, the histopathological diagnosis was MCN-L. The postoperative course was uneventful, and the patient was discharged 24 days after surgery. The patient is currently alive without recurrence 22 months after the surgery. Conclusion Although MCN-L rarely communicates with the bile duct, it is necessary to consider that MCN-L could grow into the bile duct, occasionally causing obstructive jaundice.

Abstract
A 76-year-old male was diagnosed as locally advanced pancreatic cancer because abdominal CT scan revealed a pancreatic head tumor with involvement of the proper hepatic artery. Gemcitabine plus nab-paclitaxel was initiated, but was discontinued because interstitial pneumonia was occurred. The treatment was switched to S-1 therapy and achieved stable disease for 22 months. Therefore, conversion surgery was scheduled. Because stenosis of the celiac artery origin due to median arcuate ligament(MAL)compression and dilatation of pancreatoduodenal artery arcade were observed, laparoscopic MAL section was performed. The patient was discharged on postoperative day 5 without complications. Postoperative CT scan revealed no stenosis of the celiac artery origin and disappearance of dilatation of pancreatoduodenal artery arcade. On postoperative day 14, subtotal stomach-preserving pancreaticoduodenectomy(PD)with portal vein resection was performed. The patient was discharged on postoperative day 19 without complications. Two-staged PD after MAL section make possible to evaluate blood flow accurately and select an appropriate operative method. Laparoscopic MAL section is minimally invasive and may be useful for two-staged PD in patients with celiac axis stenosis.

Abstract
This study aimed to assess short-term and long-term outcomes and to identify the factors that affect outcomes for patients with colorectal cancer aged 80 years or older. Two hundred patients with colorectal cancer who were underwent resection of the primary tumor between January 2013 and December 2018 were enrolled. Short-term outcomes of elderly patients with poor PS and of those who take antithrombotic agents and of those who were underwent open surgery were poor. Long-term outcomes of elderly patients with high GNRI and of those who were underwent D3 lymph nodes dissection were better. Laparoscopic surgery with D3 lymph nodes dissection for elderly patients who were more than 80 years old should be useful to improve short- and long-term outcomes. GNRI might be a prognostic predictive factor for patients with colorectal cancer aged 80 years or older.

Abstract
Persistent descending mesocolon(PDM)is caused by absence of fusion of the descending colon to the retroperitoneum. A 67-year-old man with bloody stools was diagnosed with rectal cancer on colonoscopy. A computed tomography showed a medial displacement of his descending colon. The preoperative clinical diagnosis was rectal cancer with PDM, and robot assisted low anterior resection was performed. We found that the left-sided colon was shifted to the midline and adhered the cecum and the mesentery of small intestine. Robot assisted surgery enables surgery with the precise adhesiotomy in a stable field. PDM is a relatively rare anatomic abnormality. Character of PDM is adhesion between the left-sided colon and other organs and radially branch from the inferior mesenteric artery. It is important to understand the anatomical characteristics of PDM and to improve on existing surgical procedures to ensure safe robot assisted surgery these patients.

Abstract
We examined 14 cases who underwent robotic rectal resection with neoadjuvant chemotherapy(NAC)or neoadjuvant chemoradiation therapy(NACRT)for local advanced rectal cancer in our hospital from 2018 June to 2020 December. Two patients underwent NACRT, 12 patients underwent NAC. Sex was 10 males and 4 females. The median age was 66. The surgical procedure was ISR 2 cases, LAR 8 cases, APR 4 cases. The median operation time was 397 minutes and the median blood loss was 73 mL. The histological response grade were Grade 3: 1 case, 2: 7 cases, 1b: 3 cases, and 1a: 3 cases. Surgical margin was negative in all cases. Postoperative complications(≥Clavien-Dindo Grade Ⅲ)required reoperation due to intestinal obstruction in 1 case. Urinary dysfunction was nothing in all cases. Although long-term results such as prognosis and function preservation need to be examined, short-term results of robot-assisted rectal resection after NAC or NACRT were generally good.

Abstract
BACKGROUND The effectiveness and extent of regional lymph node dissection in primary duodenal cancer (DC) remains unclear. This study aimed to analyze the prognostic factors and lymph node metastasis (LNM) patterns in DC. METHODS Fifty-three patients who underwent surgical resection for DC between January 1998 and December 2018 at two institutions were retrospectively analyzed. Univariate and multivariate analyses were performed on the prognostic factors of resected DC. Moreover, the relationships between depth of tumor invasion and incidence of LNM and between tumor location and LNM stations were analyzed. RESULTS The five-year survival rate of the study population was 68.9%. Multivariate survival analysis demonstrated that histologic grade G2-G4, presence of LNM, pT3-4, and elevated preoperative CA19-9 were the independent poor prognostic factors. No patient with pTis-T2 had LNM. On the other hand, LNM was found in 70% of patients with pT3-4. Among 36 patients who underwent pancreaticoduodenectomy (PD), LNM around the pancreatic head was observed, regardless of the duodenal cancer site, including the duodenal bulb and the third to the fourth portion. CONCLUSIONS Histologic grade G2-G4, presence of LNM, pT3-T4, and elevated preoperative CA19-9 were the independent poor prognostic factors in patients with resected DC. Our results suggested that lymph node dissection could be omitted for DC Tis-T1a. Moreover, based on the high frequency of LNM in T3-4 cases, PD with lymph node dissection in the pancreatic head region was considered necessary for T3-4 DC at any site.

Abstract
A 66‒year‒old man was admitted to our hospital because of anemia and a positive fecal occult blood test in the medical examination. Colonoscopy revealed a type 2 advanced sigmoid colon cancer with circular stenosis. Computed tomography (CT)colonography was performed to examine the oral colon. The apple core signs were found both in the sigmoid and transverse colon. We diagnosed a double colon cancer and performed a laparoscopic left hemicolectomy and sigmoidectomy. The tumor was histopathologically diagnosed as a multiple cancer including a transverse and a sigmoid colon cancer. Although evaluations of the intestine for colon cancer with stenosis are performed by enema examination or endoscopic examination after colon stent placement, both examinations are invasive. CT colonography is considered to be a minimally invasive and an effective preoperative examination for colorectal cancer with stenosis.

Abstract
We examined 22 cases who underwent preoperative chemotherapy in our hospital from 2013 April to 2018 December. Seven patients were treated as neoadjuvant chemotherapy(NAC). Out of 15 patients with unresectable diseases before chemotherapy, 6 patients were able to R0 resection after chemotherapy(conversion). Although only one patients was underwent RM1 resection, the other patients were underwent RM0 resection. The median overall survival was 42 months in NAC group, 28 months in conversion group, and 17 months in palliative resection group, respectively. Recurrence was observed in 1 patient in NAC group, however, all patients had recurrent disease in conversion group. In this study, although further examination should be done according to the clinical significance of preoperative chemotherapy, preoperative chemotherapy may be carried out without severe adverse event and severe postoperative complication.

Abstract
A 82-year-old female had received radiofrequency ablation for hepatocellular carcinoma(HCC)in segment 2 30 months before surgery. One month before surgery, enhanced CT showed enhanced lesion about 20 mm in diameter in the abdominal wall along the needle-tract. There was no other recurrent lesion including liver. We diagnosed the lesion as needle-tract implantation and she underwent surgical resection of the abdominal rectus muscle and sheath including needle-tract. The pathological findings revealed well differentiated HCC. After the surgery, she underwent transcatheter arterial embolization for the recurrent HCC in segment 3 and segment 4. Twenty one months after the surgery, she has been alive without recurrence. Our case demonstrated that surgical resection of the needle-tract implantation of the HCC is one of the useful therapeutic options for the selected patients.

Abstract
A 66-year-old female with upper abdominal pain was diagnosed the pancreatic tail cancer infiltrating into the stomach and transverse colon by computed tomography(CT). Umbilical metastasis(so called Sister Mary Joseph's nodule)and peritoneal metastases in pouch of Douglas were detected by FDG-PET. The patient was diagnosed as unresectable pancreatic cancer with distant metastases. Thus, she received FOLFIRINOX therapy. After 9 courses of FOLFIRINOX therapy and 15 courses of FOLFIRI therapy, the pancreatic tumor shrunk on CT. In addition, umbilical metastasis and peritoneal metastases disappeared on FDG-PET. Therefore, conversion surgery was scheduled. Fourteen months after the initial treatment, we performed distal pancreatectomy with left adrenalectomy partial gastrectomy, transverse colectomy, and umbilical resection. The patient was discharged 15 days after the operation without serious complications. Histopathological findings revealed the presence of adenocarcinoma infiltrating into the preperitoneal adipose tissue in the umbilicus. Histological therapeutic effect was Grade Ⅰb according to the 7th Edition of the General Rules for the Study of Pancreatic Cancer. Seven months after the operation, local recurrence was showed. The patient is still alive 2 years and 5 months since the initial treatment.

Abstract
A 42-year-old man, after remission of MALT lymphoma of the small intestine, was repeatedly hospitalized because of abdominal pain and severe dehydration caused by frequent vomiting and watery diarrhea. His symptoms would improve quickly every time when he was fasted and inserted a nasogastric tube. We were unable to find abnormalities on endoscopic examination and computed tomography. He was suspected to have gastrinoma because of active bleeding from a duodenal ulcer. High-level serum gastrin, endoscopic ultrasound, somatostatin receptor scintigraphy, and selective arterial calcium injection test were done. He was diagnosed with pancreatic gastrinoma in the pancreatic head by endoscopic ultrasound fine needle aspiration and subsequently underwent pancreatoduodenectomy. Histopathologic findings showed a 3-mm neuroendocrine tumor located in the duodenal submucosal layer. The presence of metastasis was confirmed in one of the peripancreatic lymph nodes. The pancreatic gastrinoma in the pancreatic head that we initially diagnosed was a lymph node metastasis behind the pancreas. Because additional resection was performed on the duodenum, we were able obtain a diagnosis of duodenal gastrinoma.

Abstract
INTRODUCTION This study aimed to investigate the predictive factors and classifications for difficulty of laparoscopic repeated liver resection (LRLR) in patients with recurrent hepatocellular carcinoma. METHODS Sixty patients who underwent LRLR were included. Potential predictive factors for difficult LRLR included the approach of the previous liver resection (laparoscopic or open), the number of previous liver resections, a history of cholecystectomy in previous liver resection, the operative procedure of previous liver resection, whether the tumor was near the resected site of the previous liver resection, non-surgical treatments before the present surgery, and the difficulty scoring system for laparoscopic liver resection. The relationship between these factors and perioperative outcomes were evaluated to investigate the predictive factor for difficult LRLR. RESULTS Univariate and multivariate analyses demonstrated that an open approach during previous liver resection, two or more previous liver resections, a history of previous liver resection with not less than sectionectomy, tumor near the resected site of the previous liver resection, and intermediate or high difficulty in the difficulty scoring system were independent risk factors for prolonged operative time and/or severe adhesion of LRLR. Three difficulty classifications were then suggested based on the number of these five predictive factors. The difficulty classification reflected operative time, intraoperative blood loss, and incidence of postoperative complication. CONCLUSION The difficulty of LRLR may be predicted by three difficulty classifications using five preoperative predictive factors.

Abstract
BACKGROUND Nonocclusive mesenteric ischemia (NOMI) has been reported to be a life-threating disease. Gastric conduit necrosis is known as a critical postoperative complication after esophagectomy for esophageal cancer. We encountered a rare case of NOMI of a wide area of the intestine accompanied by gastric conduit necrosis after esophagectomy, which was successfully treated with an emergency operation. CASE PRESENTATION A 67-year-old man presented with dysphagia. He was diagnosed with middle thoracic advanced esophageal cancer. After neoadjuvant chemotherapy, he underwent subtotal esophagectomy with lymphadenectomy and gastric conduit reconstruction. On postoperative day (POD) 2, he had diarrhea, high fever, and low blood pressure, which were treated with catecholamines. Laboratory data revealed acidosis and severe sepsis with multi-organ failure, including the kidneys. Although enhanced computed tomography did not exhibit definite findings of bowel ischemia, upper gastrointestinal endoscopy revealed necrotic mucosal changes in the whole gastric conduit. Therefore, we made a diagnosis of septic shock caused by gastric conduit necrosis and performed an emergency operation. When we explored the abdominal cavity, we found not only gastric conduit necrosis but also intermittent necrotic changes in the intestinal wall from the jejunum to the rectum. Therefore, NOMI was diagnosed. We performed an excision of the gastric conduit and 2 m of the small intestine, as well as total colectomy. After the second operation, prostaglandin E1 was administered intravenously as the treatment for NOMI, and sepsis was improved. On POD 122, he was self-discharged. He died of recurrence of lung metastasis from the esophageal cancer 9 months after the first operation. CONCLUSION When a patient has a critical status, including severe sepsis or severe acidosis, after esophagectomy, we should consider the possibility of NOMI in addition to gastric conduit necrosis and aim to diagnose and treat it immediately with an urgent operation.

Abstract
CASE A 76-year-old man was referred to our hospital for advanced hepatocellular carcinoma(HCC)with chronic hepatitis type B. Although he underwent right anterior sectionectomy and S3 segmentectomy, multiple recurrences were found in the hepatic remnant after 2 months. Transcatheter arterial chemoembolization(TACE)and transcatheter arterial infusion (TAI)were performed separately. One and a half month after the last TAI, AFP and PIVKA-Ⅱ levels markedly elevated, and multiple early enhancing nodules with portal vein tumor thrombosis were detected on CT. A half dose of sorafenib(400mg/ day)was administered to the patient who was refractory to TACE. Sorafenib was discontinued after 4 weeks because the patient developed general fatigue and anorexia(Grade 3). Furthermore, these adverse events became worse, and ascites appeared. He was hospitalized in the palliative care unit for best supportive care for 3 weeks and also received outpatient treatment for more than 14 months. Fifteen months after discontinuing sorafenib administration, his condition improved dramatically, and CT revealed that the multiple HCC had reduced in size. Moreover, the portal vein tumor thrombosis disappeared. As his performance status and liver function were well preserved, he underwent partial hepatectomy for residual HCC. The patient remains alive without recurrence at 18 months, despite no administration of sorafenib. CONCLUSION This case demonstrates that sorafenib administration combined with surgical treatment could possibly cure advanced HCC refractory to TACE.

Abstract
The patient was an 81-year-old woman. She had undergone extended cholecystectomy with lymph node dissection for primary gallbladder cancer. The pathological diagnosis was moderately differentiated tubular adenocarcinoma(pT2, N0, M0, pStage Ⅱ). Eleven months after the initial surgery, dynamic CT revealed a solitary low-enhanced tumor in S5 ofthe liver. As the tumor was detected with abnormal FDG uptake by PET-CT, we diagnosed the patient with a metastatic liver tumor from gallbladder cancer. Although chemotherapy was considered, conservative treatment was selected as the patient did not want to undergo chemotherapy. Therefore, laparoscopic partial liver resection was performed 15 months after the initial surgery with the consideration that no other distant metastasis was found, and tumor markers were within normal ranges. The postoperative course was uneventful, and the patient was discharged 13 days after liver resection without any morbidities. The resected tumor was pathologically diagnosed as a metastatic liver tumor from gallbladder cancer. She has achieved 18 months recurrence free survival after the liver resection without adjuvant chemotherapy. Although liver resection for a metastatic liver tumor from gallbladder cancer is not a standardized treatment, it may be a therapeutic option in cases of limited metastasis.

Abstract
INTRODUCTION We investigated the indications for laparoscopic liver resection (LLR) of mass-forming intrahepatic cholangiocarcinoma (MF-ICC), including the need for lymph node dissection for improved postoperative prognosis. METHODS This study involved 36 patients who underwent surgery for solitary peripheral MF-ICC. Fifteen patients underwent LLR, and 21 underwent open liver resection (OLR). Surgical outcomes and prognostic factors were investigated to determine the indications for LLR. RESULTS No significant differences were observed in perioperative outcomes between patients who underwent LLR and OLR. A significantly worse disease-free survival (DFS) rate was observed in patients who preoperatively had a tumor diameter ≥3 cm, vascular invasion on diagnostic imaging, and elevated serum carbohydrate antigen (CA) 19-9 and carcinoembryonic antigen (CEA) levels. A significantly worse overall survival (OS) rate was observed in patients with a tumor diameter ≥3 cm, vascular invasion on diagnostic imaging, and elevated serum CA19-9 levels. Therefore, a tumor diameter ≥3 cm, vascular invasion on diagnostic imaging, and elevated serum CA19-9 and CEA levels were determined to be preoperative prognostic factors. DFS and OS rates were significantly better in patients without these factors. Moreover, in six patients without these factors who underwent LLR, neither lymph node metastasis nor postoperative recurrence was observed. CONCLUSION A tumor diameter ≥3 cm, vascular invasion on diagnostic imaging, and elevated serum CA19-9 and CEA levels are preoperative prognostic factors for peripheral MF-ICC. LLR is indicated for patients without these factors.

Abstract
A 67-year-old woman was diagnosed with borderline resectable pancreatic cancer and obstructive jaundice. A covered self-expandable metallic stent(SEMS)was placed endoscopically. Neoadjuvant chemotherapy with gemcitabine plus nabpaclitaxel was provided. Forty-seven days after the SEMS placement, she presented with hematemesis. Computed tomography revealed migration of SEMS into the small bowel. No pseudoaneurysms were detected. Upper digestive endoscopy demonstrated hemobilia without obvious causes of bleeding in the stomach or duodenum. As hemorrhage recurrence was confirmed in the bile duct, we performed pancreaticoduodenectomy. Thus, bile duct hemorrhage can occur in patients with pancreatic cancer after SEMS placement.

Abstract
Abstract
Background
Introduction: Several studies have reported that durable polymer drug-eluting stents could cause delayed healing and late catch-up. Although biodegradable polymer everolimus-eluting stents (BP-EES) might solve these problems, there is few data about mid-term clinical outcomes of BP-EES compared with durable polymer everolimus-eluting stents (DP-EES).
Purpose
This study aimed to compare mid-term clinical outcomes between BP-EES and DP-EES.
Methods
Between January to December 2016, 206 consecutive patients were treated with BP-EES and 177 consecutive patients were treated with DP-EES in our Heart Center. The primary endpoint was 3-year cumulative incidence of target lesion failure (TLF) defined as cardiac death, target vessel-related myocardial infarction and clinical-driven target lesion revascularization. Moreover, clinical-driven target vessel revascularization (TVR) and definite stent thrombosis (ST) were also evaluated.
Results
After propensity score matching, 160 patients were selected in each group. At 3 years, the cumulative incidences of TLF were 4.1% in BP-EES group vs. 7.9% in DP-EES (p = 0.12). Similarly, those of clinical-driven TVR were not different between the 2 groups (10.9% vs. 8.0%, p = 0.39). The incidence of definite ST in BP-EES tended to be higher than in that of DP-EES (BP-EES vs. DP-EES; 0% vs. 1.8%, p = 0.06).
Conclusions
There were no significant differences of TLF between BP-EES and DP-EES within 3 years. In this study, BP-EES seems to prevent definite ST and be safer than DP-EES in mid-term.

Abstract
BACKGROUND Prospective studies are needed to understand the safety and feasibility of laparoscopic pancreatectomy. The aim of the present study was to describe laparoscopic pancreatectomy currently undertaken in Japan, using a prospective registration system. METHODS Patient characteristics and planned operations were registered preoperatively, and then the performed operation and outcomes were reported using an online system. Collected data were also compared between institutions based on their level of experience. This study was registered with UMIN000022836. RESULTS Available data were obtained from 1,429 patients at 100 Japanese institutions, including 1,197 laparoscopic distal pancreatectomies (LDPs) and 232 laparoscopic pancreatoduodenectomies (LPDs). The rates of completion for planned operations were 92% for LDP and 91% for LPD. Postoperative complication rates after LDP and LPD were 17% and 30%, and 90-day mortality rates were 0.3% and 0.4%, respectively. Shorter operation time, less blood loss, and lower incidence of pancreatic fistula were observed in institutions experienced in LDP. A higher rate of pure laparoscopic procedure and shorter operation time were noted in institutions experienced with LPD. CONCLUSION LDPs and LPDs are performed safely in Japan, especially in experienced institutions. Our data could support the next challenges in the field of laparoscopic pancreatectomy.

Abstract
A 74-year-old woman presented with epigastric pain. Imaging revealed a tumor measuring 80 mm, with internal necrosis, originating from the gallbladder and invading the liver. We performed extended anterior segmentectomy of the liver and lymph node resection following a preoperative diagnosis of gallbladder cancer. Histologically, the tumor was diagnosed as an undifferentiated carcinoma of the gallbladder. Although curative resection was performed, the patient developed recurrence with liver metastasis and peritoneal dissemination after 6 postoperative weeks and died after 10 postoperative weeks.

Abstract
In June 2018, a 75-year-old woman was admitted for right upper quadrant pain. She had a history of radical mastectomy for left breast cancer in April 2009. The axillary lymph node, bone, gastric, and pleural metastases had been treated with hormonal therapy for 2 years from April 2016. Based on the examination findings, we diagnosed her with acute calculous cholecystitis and performed emergency percutaneous transhepatic gallbladder drainage(PTGBD). Eleven days after PTGBD, we performed laparoscopic cholecystectomy. Pathological examination revealed a metastatic tumor from breast cancer in her gallbladder. Although her postoperative course was uneventful, the patient died of progression of the other organ metastasis 7 months after cholecystectomy. Gallbladder metastasis should be considered in patients with advanced breast cancer who present symptoms of cholecystitis.

Abstract
Abstract
Objectives
We sought to evaluate the efficacy of plaque debulking by directional coronary atherectomy (DCA) before 2nd generation drug-eluting stent (DES) implantation for bifurcated coronary lesions.
Background
Percutaneous coronary intervention (PCI) for bifurcated lesions still remains complex and challenging in terms of restenosis or stent thrombosis regardless of whether simple or complex stenting used.
Methods
Patients with bifurcated lesions were enrolled in this prospective multicenter registry. Pre-2nd generation DES plaque debulking with a novel DCA was conducted. All patients were scheduled to perform a follow up (9–12 months) angiography (coronary angiography or coronary computed tomography). The primary end point was the target vessel failure (TVF) at follow-up. Secondary end points were procedure-related events and major adverse cardiac events at 1 year.
Results
A total of 77 patients with bifurcated lesions were enrolled. PCI with DCA was performed successfully in all without any major procedure-related event and only 1 case needed complex stenting. TVF rate at 9–12 months follow up was 3.9% (3 of 77) and those were all associated with revascularization of the target vessel. Restenosis was only observed at ostial of main-branch in 3cases. No death, no coronary artery bypass grafting, and no myocardial infarction were reported in the patients within the first year.
Figure1
Conclusion
DCA before 2nd generation DES implantation can possibly avoid complex stenting and provide a good mid-term outcome in patients with bifurcated lesions.

Abstract
Abstract
Background and introduction
Diabetic patients are at high risk of adverse cardiovascular events after percutaneous coronary intervention (PCI) even with durable polymer drug-eluting stents. A biodegradable polymer everolimus-eluting stents (BP-EES) might improve clinical outcomes in patients with diabetes mellitus.
Purpose
This study aimed to compare the mid-term clinical outcomes between BP-EES and durable polymer everolimus-eluting stents (DP-EES) in diabetic patients.
Methods
We investigated consecutive 383 patients treated with BP-EES or DP-EES at our Heart Center between January and December 2016. Among these patients, 155 (40.5%) patients had diabetes mellitus. The primary endpoint was 3-year cumulative incidence of target lesion failure (TLF) defined as target vessel-related myocardial infarction (MI) and clinical-driven target lesion revascularization (TLR). Moreover, the incidence of definite stent thrombosis (ST) was also evaluated.
Results
After propensity score matching, 148 patients were divided into 2 groups (BP-EES; N=74, DP-EES; N=74). The 3-year cumulative incidences of TLF were significantly lower in BP-EES group than in DP-EES group (BP-EES vs. DP-EES; 1.4% vs. 11.4%, p=0.01). The incidence of cardiac death, target vessel-related MI, and definite ST were none in the both group.
Figure 1
Conclusions
In diabetic patients, the incidence of TLR within 3 years was significantly lower in BP-EES than in DP-EES. In PCI for diabetic patients, BP-EES might improve clinical outcomes compared to DP-EES.

Abstract
An 82-year-old female underwent contrast computed tomography (CT) that revealed multiple ring-like enhanced masses in the pancreatic tail. Additionally, the inside of the masses showed enhancement on contrast endoscopic ultrasound (EUS). She was diagnosed with a pancreatic neuroendocrine tumor on histopathological examination after EUS-guided fine-needle aspiration, and distal pancreatectomy and splenectomy were performed. In the resected specimen, toward the tumor center, tumor cells with lipid droplets and fibrosis were remarkably observed. These rare histopathological features well reflected the image findings of contrast CT and contrast EUS.

Abstract
A 70's man underwent subtotal stomach preserving pancreatoduodenectomy(SSPPD)for pancreatic head cancer. The pathological diagnosis was adenosquamous carcinoma(ASC)of the pancreas. Two months after surgery, a recurrent tumor in the remnant pancreas was confirmed with a CT scan and suspected to be ASC by endoscopic ultrasound-guided fine needle aspiration(EUS-FNA). As the recurrent lesion was limited in the pancreas, total remnant pancreatectomy(TP)was performed 4 months after SSPPD. The final pathological diagnosis was ASC. Two months after TP, liver and para-aortic lymph node metastases were revealed. The patient has been alive for 14 months after SSPPD with chemotherapy. Because of its rarity, it is difficult to implement treatment plans for recurrent ASC in the remnant pancreas.

Abstract
BACKGROUND Insufficient information is available on the relationship between obesity and outcome of paediatric patients with acute pancreatitis. OBJECTIVES This study aimed to investigate the effect of obesity on outcomes of paediatric patients with acute pancreatitis based on a national administrative database. METHODS A total of 500 cases in 416 paediatric patients with acute pancreatitis (aged 5-17 years) were referred from 260 hospitals between 2010 and 2012 in Japan. Patients were divided into two groups according to the presence of obesity: with obesity (n = 65) and without obesity (n = 435). Patient data were collected from the administrative database to compare the prevalence of severe acute pancreatitis, in-hospital mortality, length of stay (LOS) and medical costs between the groups. RESULTS Both prevalence of severe acute pancreatitis and in-hospital mortality were significantly higher in paediatric patients with obesity than those without (36.9% vs. 16.3% and 3.1% vs. 0.0%; P < 0.001, respectively). Longer LOS and higher medical costs were also observed in paediatric patients with obesity (25.7 vs. 15.2 days, P < 0.001 and 14 169.5 vs. 7457.7 US dollars, P < 0.001, respectively). CONCLUSION This study demonstrated that obesity significantly influenced the outcomes of paediatric acute pancreatitis.

Abstract
BACKGROUND Anaplastic pancreatic cancer (APC) cell lines have been scarcely established. METHODS The morphology, gene expressions, karyotyping and epithelial-mesenchymal transition markers of newly established APC cell lines OCUP-A1 and OCUP-A2 were analyzed. Their abilities of proliferation under normoxia and hypoxia, migration and invasion were compared to 4 commercially available pancreatic ductal adenocarcinoma (PDA) cell lines. Their induction of angiogenesis, stem-like cell population and subcutaneous tumor growth in nude mice were estimated, comparing 2 PDA cell lines examined here. RESULTS OCUP-A1 and OCUP-A2 cells continuously grew with spindle and polygonal shapes, respectively. Gene analysis revealed 9 gene mutations including KRAS and TP53. Karyotyping clarified numerical structural abnormalities in both cells. Loss of E-cadherin and expression of vimentin in both cell lines were observed. The doubling time of both cell lines was approximately 20 h. Proliferation, migration and invasion abilities were not notable compared to other PDA cell lines. However stem-like cell population of both cell lines was superior to a part of PDA cell lines. Moreover OCUP-A1 showed stronger hypoxia tolerance and induction of angiogenesis than other PDA cell lines. The tumorigenicity in vivo of OCUP-A2 was stronger than conventional PDA cell lines. CONCLUSIONS The OCUP-A1 and OCUP-A2 cell lines of rare malignancies might be useful for investigating the biology of pancreatic cancer.

Abstract
This phase III study is the first study to demonstrate the superiority of new oral fluoropyrimidine S-1 over tegafur–uracil as adjuvant chemotherapy for stage II/III rectal cancer patients with no preoperative treatment in terms of relapse-free survival. S-1 can be considered an important option, especially for patients who have not received preoperative treatment. Backgrounds Preventing distant recurrence and achieving local control are important challenges in rectal cancer treatment, and use of adjuvant chemotherapy has been studied. However, no phase III study comparing adjuvant chemotherapy regimens for rectal cancer has demonstrated superiority of a specific regimen. We therefore conducted a phase III study to evaluate the superiority of S-1 to tegafur–uracil (UFT), a standard adjuvant chemotherapy regimen for curatively resected stage II/III rectal cancer in Japan, in the adjuvant setting for rectal cancer. Patients and methods The ACTS-RC trial was an open-label, randomized, phase III superiority trial conducted at 222 sites in Japan. Patients aged 20–80 with stage II/III rectal cancer undergoing curative surgery without preoperative therapy were randomly assigned to receive UFT (500–600 mg/day on days 1–5, followed by 2 days rest) or S-1 (80–120 mg/day on days 1–28, followed by 14 days rest) for 1 year. The primary end point was relapse-free survival (RFS), and the secondary end points were overall survival and adverse events. Results In total, 961 patients were enrolled from April 2006 to March 2009. The primary analysis was conducted in 480 assigned to receive UFT and 479 assigned to receive S-1. Five-year RFS was 61.7% [95% confidence interval (CI) 57.1% to 65.9%] for UFT and 66.4% (95% CI 61.9% to 70.5%) for S-1 [P = 0.0165, hazard ratio (HR): 0.77, 95% CI 0.63–0.96]. Five-year survival was 80.2% (95% CI 76.3% to 83.5%) for UFT and 82.0% (95% CI 78.3% to 85.2%) for S-1. The main grade 3 or higher adverse events were increased alanine aminotransferase and diarrhea (each 2.3%) in the UFT arm and anorexia, diarrhea (each 2.6%), and fatigue (2.1%) in the S-1 arm. Conclusion One-year S-1 treatment is superior to UFT with respect to RFS and has therefore become a standard adjuvant chemotherapy regimen for stage II/III rectal cancer following curative resection.

Abstract
Sorafenib has been a standard therapy for advanced hepatocellular carcinoma (HCC) with portal vein thrombosis. Hepatic arterial infusion chemotherapy (HAIC) is still preferably performed in Japan because of its relatively good tumor-shrinking effect. We report a case of advanced multiple HCC with portal thrombus that responded to combination chemotherapy with sorafenib and repeat hepatic arterial infusion with a fine-powder formulation of cisplatin (IA-call®). A 57-year-old man presented for the treatment of HCC with alcoholic cirrhosis. Multiple HCC were found to be rapidly progressing with portal thrombosis. HAIC with IA-call® was performed, but the tumors progressed. TAE was performed 3 times thereafter and the main tumor shrunk to some extent. A month after the last TAE, the HCC was found to progress again, and oral sorafenib was administered. A reservoir and catheter were placed and HAIC with low-dose 5-fluorouracil and cisplatin was performed for 3 cycles following 1 HAIC cycle with epirubicin and mitomycin C, which was not effective. For 10 months after initial therapy, HAIC using IA-call® has been performed once for 6 weeks. After performing HAIC with IA-call® 5 times, the serum levels of HCC tumor markers AFP and PIVKA-Ⅱdecreased, and the tumors continued to shrink and were not stained on enhanced CT scan. The patient has been alive for 23 months after the initial therapy and has maintained stable disease.

Abstract
The prognosis of HCC with vascular invasion is dismal, but surgery is elected when the hepatic reserve is adequate. The case involved a 68-year-old male HCV carrier. A 10 cm diameter tumor occupying the central 2 segments of the liver and liver metastasis in the left lobe were detected. The patient was diagnosed with multiple HCC with severe vascular invasion of Vp2 and Vv3. The tumor shrunk dramatically after starting HAIC therapy with cisplatin and oral administration of sorafenib. A laparoscopic partial hepatectomy was performed for the viable lesion. The tumor showed almost complete coagulative necrosis. Multiple hepatic metastases were found 4 months after surgery, but the tumor was under control at 25 months after the first HAIC due to HAIC, oral administration of sorafenib, and RFA. An improved prognosis for multiple HCC with severe vascular invasion can be expected by performing multidisciplinary treatments including surgery.

Abstract
This chapter covers a range of important topics of laparoscopic hepatectomy as a novel approach toward treatment of liver cancer. Although laparoscopic hepatectomy was performed in a limited number of centers in the 1990s, technological innovations, improvements in surgical techniques and accumulation of experience by surgeons have led to more rapid progress in laparoscopic hepatectomy in the late 2000s for minimally invasive hepatic surgery. Currently, laparoscopic hepatectomy can be performed for all tumor locations and several diseases via several approaches. The laparoscopic approach can be applied to several types of resection, not only for tumors but also for liver transplantation, with equivalent or better results compared with those obtained with open surgery. Therefore, laparoscopic hepatectomy will become a standard procedure for treatment of liver cancer in the near future.

Abstract
BACKGROUND/AIMS A soft-coagulation system (SCS) was introduced as an effective device to reduce blood loss in hepatectomy. Here we evaluated the efficacy of a two-surgeon technique using precoagulation by an SCS and the Cavitron Ultrasonic Surgical Aspirator (CUSA) for liver transection. METHODOLOGY The 163 patients with liver tumors were divided into two groups (conventional group and two-surgeon group). Liver transection was conducted using saline-coupled bipolar electrocautery and CUSA in 102 patients (conventional group). In 61 patients (the two-surgeon group), a two-surgeon technique using precoagulation by an SCS and CUSA for liver resection was performed. RESULTS The median blood loss was significantly less in the two-surgeon group compared to the conventional group (354.8 mL vs. 557.8 mL, respec tively: p = 0.0011). The postoperative hospital stay was significantly shorter in the two-surgeon group compared to the conventional group (12.7 days vs. 15.5 days, p = 0.0035). CONCLUSIONS The two-surgeon technique using precoagulation by an SCS and CUSA was significantly reduced blood loss during liver transection, and associated with low morbidity and mortality. This technique may be useful for many hepatobiliary surgeons.

Clinical and pathological features of five-year survivors after pancreatectomy for pancreatic adenocarcinoma. World J Surg Oncol 2014; 12:360. [PMID: 25429841 PMCID: PMC4289316 DOI: 10.1186/1477-7819-12-360] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2014] [Accepted: 11/06/2014] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Clinical factors determining short-term survival after pancreatectomy have been well studied, but factors predicting long-term survival with curative resection are poorly understood in pancreatic carcinoma. Our objective was to identify clinical and pathological features of five-year disease-free survivors after surgical resection of pancreatic adenocarcinoma. METHODS The clinical and pathological data from 147 patients who underwent a potentially curative resection for pancreatic adenocarcinoma at our institution between 1988 and 2012 were retrospectively analyzed. RESULTS Of 147 patients, 18 survived for more than five years after surgery without disease recurrence. A univariate analyses demonstrated that: two or fewer lymph node metastases (P=0.014), a preoperative serum carbohydrate antigen 19-9 (CA19-9) level of 40 U/mL or less (P=0.0018), an absence of intrapancreatic nerve invasion (P=0.028), and undergoing an R0 resection (P=0.011) were significantly associated with five-year survival. A logistic regression model identified the following independent cancer-related predictors of five-year survivors: having two or fewer lymph node metastases (odds ratio (OR): 6.02; 95% confidence interval (CI): 1.08 to 112.98; P=0.0385), a preoperative serum CA19-9 level of 40 U/mL or less (OR: 5.02; 95% CI: 1.68 to 16.48; P=0.0036), and undergoing an R0 resection (OR: 3.63; 95% CI: 1.12 to 14.28; P=0.0316). CONCLUSIONS We conclude that number of lymph node metastases being two or less, a preoperative serum CA19-9 level of 40 U/mL or less, and undergoing an R0 resection may be independent predictive factors to identify actual five-year survivors after pancreatectomy for pancreatic adenocarcinoma.

Abstract
A 69-year-old man with perianal pain was diagnosed with an anal fistula and a rectal tumor by magnetic resonance imaging and pulmonary tuberculosis by computed tomography. A colonoscopy confirmed the presence of a circular mass in the rectum 6 cm from the anal verge. Histological examination revealed a moderately differentiated adenocarcinoma. Initially, seton drainage was used to improve the perianal pain. After 2 months of anti-tuberculosis therapy, the patient underwent low anterior resection for the rectal cancer. Six months after surgery, a perianal tumor was detected at the postoperative site of the anal fistula. Biopsy of the tumor revealed adenocarcinoma. Because the histological appearance of the second tumor was identical to the rectal cancer, it was diagnosed as a metastatic anal fistula cancer. The tumor shrunk after 3 courses of neoadjuvant chemotherapy with S-1 plus oxaliplatin (SOX) plus bevacizumab and there was no evidence of distant metastasis. Local resection of the anal fistula cancer was performed. Six months postoperatively, the patient is doing well and shows no sign of recurrence.
