RESUMO
BACKGROUND: Intussusception occurs when a segment of the bowel (the intussusceptum) telescopes into an adjacent segment (the intussuscipiens). Adult intussusception occurs rarely and often requires surgical resection for its treatment. We describe the case of an adult patient with extremely rare cecorectal intussusception treated using a novel combined transabdominal and trans-anal approach, which has not yet been reported in the literature. CASE PRESENTATION: A 71-year-old woman was transferred to our hospital for the treatment of upper abdominal pain. Physical examination, laboratory tests, and imaging inspections showed strangulated bowel obstruction induced by intussusception associated with the intra-rectal mass. We performed an emergency operation and treated the intussusception using a combined transabdominal and trans-anal approach. The intraoperative findings revealed bloody ascites and a potentially malignant tumor that had moved toward the anal side from peritoneal reflection. The tumor served as the lead point in the cecum with mobile cecum. After reducing the intussusception using the combined procedure, we removed the ileocecal portion. The intraoperative and histopathological findings suggested that cecum cancer with mobile cecum had caused the cecorectal intussusception. The patient had an uneventful postoperative course, except for postoperative pulmonary pneumonia. CONCLUSION: To the best of our knowledge, this is the first reported case of adult cecorectal intussusception due to cecum cancer with mobile cecum successfully treated using the combined transabdominal and trans-anal approach. This combined procedure may be useful in treating the intussusception where the lead point is distal from the peritoneal reflection.
RESUMO
OBJECTIVE: This study aimed to determine whether retrocolic alimentary tract reconstruction is noninferior to antecolic reconstruction in terms of DGE incidence after pancreatoduodenectomy (PD) and investigated patients' postoperative nutritional status. SUMMARY OF BACKGROUND DATA: The influence of the route of alimentary tract reconstruction on DGE after PD is controversial. METHODS: Patients from 9 participating institutions scheduled for PD were randomly allocated to the retrocolic or antecolic reconstruction groups. The primary outcome was incidence of DGE, defined according to the 2007 version of the International Study Group for Pancreatic Surgery definition. Noninferiority would be indicated if the incidence of DGE in the retrocolic group did not exceed that in the antecolic group by a margin of 10%. Patients' postoperative nutrition data were compared as secondary outcomes. RESULTS: Total, 109 and 103 patients were allocated to the retrocolic and antecolic reconstruction group, respectively (n = 212). Baseline characteristics were similar between both groups. DGE occurred in 17 (15.6%) and 13 (12.6%) patients in the retrocolic and antecolic group, respectively (risk difference; 2.97%, 95% confidence interval; -6.3% to 12.6%, which exceeded the specified margin of 10%). There were no differences in the incidence of other postoperative complications and in the duration of hospitalization. Postoperative nutritional indices were similar between both groups. CONCLUSIONS: This trial could not demonstrate the noninferiority of retrocolic to antecolic alimentary tract reconstruction in terms of DGE incidence. The alimentary tract should not be reconstructed via the retrocolic route after PD, to prevent DGE.

BACKGROUND: To explore best practices for acute cholecystitis, it is necessary to construct a system to assess the difficulty of laparoscopic cholecystectomy (LC) based on intraoperative findings. In this study, multiple evaluators assessed videos of LC to assemble a library of typical video clips for 25 intraoperative findings. METHODS: We have previously identified 25 items that contribute to surgical difficulty in LC. For each item, roughly 30-second video clips were submitted from videos of LC performed at member institutions. We then selected one typical video from the collected clips based on simple tabulation of the instances of agreement. Inter-rater agreement was assessed with Fleiss's κ and Gwet's agreement coefficient (AC). RESULTS: Except in the case of two assessment items ("edematous change" and "easy bleeding"), κ or AC significantly exceeded 0.5 and the typical videos were judged to be applicable. For the two remaining items, the evaluation was repeated after clarifying the definitions of positive and negative findings. Eventually, they were recognized as typical. The completed video clip library contains 31 clips and is divided into five categories (http://www.jshbps.jp/modules/project/index.php?content_id=13). CONCLUSIONS: This clip library may be highly useful in clinical settings as a more objective standard for assessing surgical difficulty in LC.

BACKGROUND: Pancreaticoduodenectomy (PD) is a standardized strategy for patients with middle and distal bile duct cancers. The aim of this study was to compare clinicopathological features of bile duct segmental resection (BDR) with PD in patients with extrahepatic cholangiocarcinoma. METHODS: Consecutive cases with extrahepatic cholangiocarcinoma who underwent BDR (n = 21) or PD (n = 84) with achievement of R0 or R1 resection in Kobe University Hospital between January 2000 and December 2016 were enrolled in the present study. RESULTS: Patients who underwent PD were significantly younger than those receiving BDR. The frequency of preoperative jaundice, biliary drainage and cholangitis was not significantly different between the two groups. The duration of surgery was longer and there was more intraoperative bleeding in the PD than in the BDR group (553 vs. 421 min, and 770 vs. 402 mL; both P<0.01). More major complications (>Clavien-Dindo IIIa) were observed in the PD group (46% vs. 10%, P<0.01). Postoperative hospital stay was also longer in that group (30 vs. 19 days, P = 0.02). Pathological assessment revealed that tumors were less advanced in the BDR group but the rate of lymph node metastasis was similar in both groups (33% in BDR and 48% in PD, P = 0.24). The rate of R0 resection was significantly higher in the PD group (80% vs. 38%, P<0.01). Adjuvant chemotherapy was more frequently administered to patients in the BDR group (62% vs. 38%, P = 0.04). Although 5-year overall survival rates were similar in both groups (44% for BDR and 51% for PD, P = 0.72), in patients with T1 and T2, the BDR group tended to have poorer prognosis (44% vs. 68% at 5-year, P = 0.09). CONCLUSIONS: BDR was comparable in prognosis to PD in middle bile duct cancer. Less invasiveness and lower morbidity of BDR justified this technique for selected patients in a poor general condition.

PURPOSES: Resected bile duct cancers often relapse during postoperative follow-up. The aim of this study was to detect predictors of early recurrence in patients with extrahepatic bile duct cancer. METHODS: Consecutive cases (n = 162) of extrahepatic bile duct cancer in which R0 or R1 resection was achieved in Kobe University Hospital between 2000 and 2016 were divided into three groups [early recurrence (ER), within 6 months of surgery, late recurrence (LR), and no recurrence (NR)] and their clinicopathological features were compared. RESULTS: Twenty-two patients (14%) developed ER and 69 (43%) developed LR after surgery. The rates of lymph node metastasis and residual cancer status were similar in all three groups. Liver metastasis was more common in the ER group than in the LR group (59% vs. 32%, p = 0.02). ER had a significantly worse prognosis than LR and NR (7% vs. 44% vs. 85% at 1 year, p < 0.01, respectively). Multivariate analysis showed that age > 75 years, serum CA19-9 > 1008 U/ml and perineural invasion were independent predictors of early recurrence. CONCLUSIONS: High serum CA19-9 values (> 1008 U/ml) were an independent predictor of early recurrence. Neoadjuvant therapy and aggressive adjuvant therapy may be beneficial for patients who show highly elevated CA19-9 values before surgery.

BACKGROUND: Acute cholecystitis (AC) after cardiovascular surgery (CS) tends to have a serious postoperative course; however, there are few reports of AC after CS. In this study, we investigated the clinical features of AC after CS. METHOD: Of 26 patients who underwent surgery for AC after CS between 2001 and 2018 were investigated. Of these patients, the severity of AC, onset time, surgical outcomes, and postoperative pathological findings were evaluated. RESULTS: Grade III accounted for 46% (12/26) of the AC after CS patients. Gallbladder drainage did not produce sufficient outcomes in all CS cases. The postoperative hospital days of AC after CS were extended (31/21 days, P = 0.07) and the postoperative pathologic findings revealed a higher rate of gangrenous cholecystitis (88/41%, P < 0.01) than the control group. With regard to the incidence of postoperative complications, there were no differences between CS and the control group (23/24%). The mortality rate of AC after CS was 12%. CONCLUSION: Because more than 80% of CS cases involved pathologically gangrenous cholecystitis, it may be necessary to perform early surgery for AC after CS, even when the severity of AC is Grade III.

BACKGROUND: The use of surgical metal clips is crucial for ligating vessels in various operations. The currently available metal clips have several drawbacks; they are permanent and interfere with imaging techniques such as computed tomography (CT) or magnetic resonance (MR) imaging and carry the potential risk of endo-clip migration. We recently developed a novel magnesium (Mg) alloy for biodegradable clips that reduces artifacts on CT imaging. This study aimed to examine the tolerance, biodegradability, and biocompatibility of the Mg alloy clips compared with those of standard titanium (Ti) clips in hepatectomy. METHODS: Thirty Wistar rats were divided into two groups based on the clip used (groups A and B). The vascular pedicle, including hepatic artery, portal vein, bile duct, and hepatic vein of the left lateral lobe, was ligated with the Ti clip in group A or the Mg alloy clip in group B, and then the left lateral lobe was removed. The rats were sacrificed at 1, 4, 12, 24, and 36 weeks after surgery. Clinical and histological evaluations were performed. Absorption rate was calculated by measuring the clip volume. RESULTS: Although the Mg alloy clips showed biodegradability over time, there were no significant differences in the serum concentration of Mg between the two groups. The remaining volume ratio of Mg alloy clips was 95.5, 94.3, 80.0, 36.2, and 16.7% at 1, 4, 12, 24, and 36 weeks, respectively. No side effects occurred. Most of the microscopic changes were similar in both groups. CONCLUSIONS: The new biodegradable Mg alloy clips are safe and feasible in vessel ligation for hepatectomy in a rat model and reduce artifacts in CT imaging compared with the standard Ti clips.

INTRODUCTION: Multimodal treatment prolongs the survival of patients with biliary tract cancer (BTC). However, the chemotherapy choices for this disease are few, and completing each chemotherapy session is important. Adjuvant chemotherapy has been attempted for BTC, but has only had a 75% completion rate. Body weight loss and cholangitis are reasons for the interruption of chemotherapy. Previous reports suggested that nutritional intervention with omega-3 fatty acids maintained body weight and improved the completion rate for chemotherapy. Moreover, omega-3 fatty acids have an anti-inflammatory effect. Therefore, we theorised that omega-3 fatty acids would improve the completion rate of adjuvant chemotherapy in patients with BTC. The aim of this study is thus to evaluate the effectiveness of omega-3 fatty acids for patients planning adjuvant chemotherapy for BTC. METHOD AND ANALYSIS: This study is a single-centre, open-label, single-arm, historically controlled study with a planned enrolment of 55 participants. Protocol treatment consists of four courses of S-1 adjuvant chemotherapy and an oral omega-3 fatty acid pharmaceutic adjuvant (LOTRIGA 2 g (Takeda Pharmaceutical Co.)), which includes 2 g of omega-3 fatty acids from day 1 until day 168 of the treatment period. The primary endpoint is the completion rate of four total courses of S-1. Secondary endpoints are postoperative cholangitis, time to recurrence or distant metastasis, changes in nutritional index, changes in the lymphocyte blast transformation test induced by phytohaemagglutinin, and concanavalin A and diamine oxidase serum activity during adjuvant chemotherapy. All adverse events will be evaluated. ETHICS AND DISSEMINATION: This protocol was approved by the Institutional Review Board of Kobe University Hospital. The findings from this study will be presented at national and international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: UMIN000031247.

BACKGROUND: This study aimed to evaluate the clinical relevance of hepatectomy for Barcelona Clinic Liver Cancer (BCLC) stages B and C advanced hepatocellular carcinoma (HCC). METHODS: A total of 314 patients (149 and 165 BCLC stages B and C, respectively) who underwent hepatectomy were included. Complete hepatectomy (without residual tumors after hepatectomy) and reductive hepatectomy (apparent residual tumors after hepatectomy) were performed for 212 and 102 patients, respectively. Short-term operative and postoperative outcomes, as well as long-term outcomes, were evaluated. RESULTS: The median survival times of patients with stage B disease undergoing complete hepatectomy and reductive hepatectomy were 48.9 and 20.1 months, respectively (p = 0.0075), whereas those of patients with stage C disease were 19.5 and 17.6 months, respectively (p = 0.0140). The 3-year overall survival rates of patients with stage B disease undergoing reductive hepatectomy with and without subsequent local treatments after surgery were 47.5% and 0%, respectively, whereas those of patients with stage C diseases were 18.6% and 0%, respectively. CONCLUSIONS: Survival benefits are obvious for both BCLC stages B and C HCC when complete hepatectomy can be performed safely. Reductive hepatectomy is also acceptable for BCLC stages B and C when subsequent local treatment for remnant liver tumors can be performed safely after reductive hepatectomy. Without subsequent local treatment, reductive hepatectomy has little clinical relevance. Thus, a cautious approach to patient selection is required for this aggressive strategy.

A 47-year-old woman who had unresectable locally advanced gallbladder cancer(GBC)accompanied with liverinvasion, duodenum invasion, transverse colon invasion, and surrounding lymphatic metastasis received 5 courses of chemotherapy with gemcitabine plus cisplatin. Afterthe chemotherapy, imaging showed down-staging of the GBC, indicating tumor shrinkage. The initial laparoscopic examination revealed no peritoneal seeding or distant metastasis. Subsequently, we performed cholecystectomy with a partial hepatectomy at the gallbladder bed. Malignant findings were not observed in the histopathological examination and the pathological diagnosis was CR with pT0N0M0, Stage 0. The patient was discharged on day 11 after the operation. There has been no recurrence at 14 months after surgery. Although the prognosis of advanced GBC with local invasion is generally poor, chemotherapy might be an effective treatment for patients with initially unresectable locally advanced gallbladder carcinoma.

Although the first-line treatment for hepatocellular carcinoma(HCC)is hepatectomy, extreme elderly(80 years or older) patients often tend to have a variety of underlying diseases and decreased cardiopulmonary function, which means that surgery involves a high risk. In this case, we examined the safety and efficacy of hepatectomy performed in an extreme elderly patient with HCC. Of the patients with HCC that underwent initial hepatectomy at Kobe University Hospital(n=348)between 2009 and 2015, 23 patients aged 80 years or older at the time of surgery(Group 1, n=23)and those younger than 80 years at the time(Group 2, n=325)were compared, based on parameters related to safety and prognosis. We did not identify differences between the 2 groups with respect to blood loss and operating time. Intraoperative blood transfusion was more common in Group 1. There was no significant difference between the 2 groups with respect to complications of Grade â ¢ or higher. The median survival of Group 2 patients following hepatectomy(42 months)was better than that of Group 1 patients(34 months), but there was no significant difference between the 2 groups(p=0.429). Furthermore, when the same parameters were compared after adjusting for and matching propensity scores, there were no significant differences in complications, hospitalization periods, and prognosis between the 2 groups. Through proper assessment of oncologic factors and patient risk factors, hepatectomy can be performed safely and effectively even for extreme elderly patients with HCC. If there is no other disease regulating the prognosis, we can expect to achieve similar prognosis in non-extreme elderly patients. Hence, treatments should not be limited solely based on a patient being extremely elderly; rather, proactive treatments should be considered.

Although surgical resection is the first-line treatment for biliary tract cancer(BTC), elderly patients often have underlying diseases and decreased cardiopulmonary function that place them at a high risk of undergoing surgery. We examined the safety and efficacy of surgical resection in elderly BTC patients. Among the BTC cases that underwent surgical resection at Kobe University Hospital from 2009 to 2015, the safety and prognosis ofthose aged 75 years or older(Group 1)were compared to those younger than 75 years(Group 2)at the time ofsurgery. Fifty-two patients with perihilar cholangiocarcinoma( Bp), 29 patients with intrahepatic cholangiocarcinoma(ICC), and 40 patients with ampulla ofVater cancer(AV) were included. There was no significant difference between the 2 groups with respect to complications of Grade â ¢or above, while surgery-related death was more common in Bp and ICC ofGroup 1. The median survival ofGroup 1 following hepatectomy for Bp and ICC(22 months)was significantly shorter than that of Group 2(40 months)(p=0.023). There was no significant difference in overall survival of Group 1 and Group 2 patients with AV(p=0.094). Surgical resection for BP and ICC for elderly patients has a higher risk of hepatectomy; therefore, precise assessment of oncologic and patient risk factors should be performed. As we can expect to achieve similar prognoses between non-elderly and elderly patients with AV, aggressive treatments should be considered for elderly patients with AV.

BACKGROUND/AIM: Hepatic venous isolation and extracorporeal charcoal hemoperfusion (HVI-CHP) can reduce systemic exposure to hepatic arterial infusion (HAI) chemotherapy. The pre-existing HVI-CHP system has limited effectiveness against high-dose cisplatin; therefore, we designed a new system and evaluated its efficacy in a canine model. MATERIALS AND METHODS: Cisplatin was administered via HAI under HVI-CHP. HVI-CHP was performed using one charcoal column in group I and two charcoal columns in group II; it was not performed in group III. The plasma cisplatin levels in the systemic circulation and at the column inlet and outlet, and the column extraction rate of were analyzed. RESULTS: The column extraction rates of free and total cisplatin in group II were significantly higher than those in group I. The systemic concentration of free cisplatin was significantly lower in group II than in groups I and III after HAI. No significant differences were observed in cisplatin concentrations in the liver tissue among all groups. CONCLUSION: A novel HVI-CHP system for HAI of cisplatin was successfully developed.

A 71-year-old woman underwent right nephrectomy for the treatment of clear cell renal cell carcinoma at the age of 53. After 15 years, surgical removal of a solitary tumor was performed in the right adrenal gland and thyroid gland; both were diagnosed as metastases of renal cell carcinoma. Eighteen years after the initial resection, computed tomography(CT) showed multiple hypervascular tumors spreading across the entire area of the pancreas. She was referred to our hospital, and endoscopic ultrasound-guided fine needle aspiration biopsy(EUS-FNA)revealed that they were metastases from the renal cell carcinoma. Total pancreatectomy and splenectomy were performed, and the patient remains alive and well with no evidence of recurrent disease 7 months after the pancreatectomy. Furthermore, her blood glucose level is well controlled with insulin therapy.

The patient was a 63-year-old man with hepatitis C. He discontinued combination therapy containing interferon and ribavirin because of the development of skin symptoms. A screening examination showed multiple early-stage hepatocellular carcinomas. He refused treatment and was followed up as an outpatient. During follow-up, his PIVKA-â ¡ level remarkably elevated to 59,994mAU/mL. Computed tomography(CT)showed an enlarged tumor with portal invasion(vp2)in segment 8 and intrahepaticmetastasis. We performed right and partial hepatectomy. Three months later, CT showed multiple lung metastases. We initiated the daily administration of 800 mg of sorafenib. However, 6 months after hepatectomy, the lung metastases increased in size and number. We considered the therapeutic effect as progressive disease(PD)according to the RECIST criteria. We then initiated administering 120 mg of regorafenib daily as second-line therapy. In a course of the treatment containing sorafenib and regorafenib, the dose was reduced due to hand-foot skin reactions. 8.5 months after hepatectomy, the lung metastases significantly decreased in size. One year after hepatectomy, almost complete response(CR) was obtained, and no intrahepatic recurrence was found.

Among the various diagnostic modalities for small bowel hemangioma, video capsule endoscopy (VCE) and double-balloon enteroscopy (DBE) can be recommended as part of the work-up in patients with obscure gastrointestinal bleeding (OGIB). DBE is superior to VCE in the accuracy of diagnosis and therapeutic potential, while in most cases total enteroscopy cannot be achieved through only the antegrade or retrograde DBE procedures. As treatment for small bowel bleeding, especially spout bleeding, localization of the lesion for the decision of DBE insertion facilitates early treatment, such as endoscopic hemostatic clipping, allowing patients to avoid useless transfusion and the worsening of their disease into life-threatening status. Applying endoscopic India ink marking prior to laparoscopic surgical resection is a particularly useful technique for more minimally invasive treatment. We report two cases of small bowel hemangioma found in examinations for OGIB that were treated with combination of laparoscopic and endoscopic modalities.

We report a case of bilobar multiple hepatocellular carcinoma(HCC)with peritoneal dissemination successfullytreated by dual treatment with reductive surgeryplus percutaneous isolated hepatic perfusion(PIHP). A 73-year-old man had sudden abdominal pain and was diagnosed bilobar multiple HCC through some examinations. The abdominal CT scan demonstrated onlya peritoneal dissemination under the liver. We performed partial hepatectomyof the lateral segment and the Spiegel lobe, and resected a peritoneal dissemination. Subsequently, we underwent PIHP twice. The tumor marker was normalized, and CT images demonstrated complete response according to the RECIST. Dual treatment is considered to be a unique therapeutic modalityfor severe advanced HCC.

A 72-year-old woman had severe watery diarrhea and weight loss. Computed tomography demonstrated a 55mm tumor in pancreatic tail with enlargement of para-aortic lymph nodes. There was no apparent liver metastasis. Endoscopic ultrasound demonstrated a well-circumscribed heterogenous tumor, which was diagnosed neuroendocrine tumor by endoscopic ultrasound-guided fine needle aspiration biopsy. For suspected VIPoma with para-aortic lymph node involvement, distal pancreatectomy and para-aortic lymphadenectomy was performed. The tumor was diagnosed as VIPoma by immunohistochemistry. The diarrhea improved after surgery. No evidence of recurrence was detected after a follow-up of 11 months.

INTRODUCTION: Bile reflux into the pancreatic duct (BRPD) is sometimes demonstrated during intraoperative cholangiography (IOC) even in patients without pancreaticobiliary maljunction. However, the clinical significance of this finding in laparoscopic and open cholecystectomy is unclear. METHODS: Among 484 patients who underwent cholecystectomy (372 laparoscopic, 112 open), patients whose pancreatic duct was depicted in IOC were selected. The value of pancreatic amylase (p-amylase) of the gallbladder bile, histological changes, and the immunohistochemical expression of proliferating cell nuclear antigen (PCNA) in the gallbladder mucosa were analyzed in patients with BRPD. The data were then compared to those in patients without BRPD whose gallbladder bile p-amylase was measured (control group, n = 20). RESULTS: The success rate of IOC was 93.6%. The rate of BRPD in laparoscopic and open cholecystectomy was 5.2% and 5.7%, respectively. The value of gallbladder bile p-amylase in patients with BRPD was significantly higher than in the control group (790.5 vs 14.0 IU/L, P = 0.034). The value of the PCNA labeling index in patients with BRPD was significantly higher than that of the control group (15.4% vs 4.1%, P = 0.0026). Among the 24 patients with BRPD, pathological changes in the gallbladder mucosa were detected in five (two hyperplasia, three metaplasia), but there was no correlation between the presence of pathological change and PCNA labeling index or gallbladder bile p-amylase. CONCLUSIONS: IOC could detect BRPD both in laparoscopic and open cholecystectomy at a similar rate. Patients with BRPD had high levels of gallbladder bile p-amylase and PCNA labeling index, findings similar to those in patients with pancreaticobiliary maljunction.

BACKGROUND: Although preoperative biliary drainage in jaundiced patients is controversial, external biliary drainage (EBD) is beneficial for infection control in patients with biliary cancers. When EBD is performed, additional bile replacement (BR) has the benefit of improving impaired intestinal barrier function, but the detailed mechanism remains unknown. We examined the effect of bile replacement on immune functions over the duration of BR in jaundiced patients. METHODS: Fifteen patients were enrolled into this prospective study. BR was started soon after the total serum bilirubin concentration reached 5.0 mg/dl and was continued for 14 days. Drained bile was given two times orally (2 × 100 ml/day). Concanavalin A (Con A)- and phytohemagglutinin (PHA)-stimulated lymphocyte proliferation and serum diamine oxidase (DAO) activity were measured before starting and during BR. Twenty patients with EBD and no BR were analyzed as a control group. RESULTS: Serum liver enzymes, prothrombin time-international normalized ratio (PT-INR), and responses to Con A and PHA gradually improved over the 14 days of BR, but percentages of lymphocytes and DAO levels did not. PT-INR, and Con A and PHA responses did not improve during EBD in the control group. PT-INR significantly decreased in patients with a greater fraction of their drained bile replaced. CONCLUSIONS: Our results indicate that preoperative BR using as large a quantity of bile as possible is useful for improving blood coagulability and cellular immunity in patients with EBD.
