Abstract
BACKGROUND Prevention of bile duct injury and vasculo-biliary injury while performing laparoscopic cholecystectomy (LC) is an unsolved problem. Clarifying the surgical difficulty using intraoperative findings can greatly contribute to the pursuit of best practices for acute cholecystitis. In this study, multiple evaluators assessed surgical difficulty items in unedited videos and then constructed a proposed surgical difficulty grading. METHODS We previously assembled a library of typical video clips of the intraoperative findings for all LC surgical difficulty items in acute cholecystitis. Fifty-one experts on LC assessed unedited surgical videos. Inter-rater agreement was assessed by Fleiss's κ and Gwet's agreement coefficient (AC). RESULTS Except for one item ("edematous change"), κ or AC exceeded 0.5, so the typical videos were judged to be applicable. The conceivable surgical difficulty gradings were analyzed. According to the assessment of difficulty factors, we created a surgical difficulty grading system (agreement probability = 0.923, κ = 0.712, 90% CI: 0.587-0.837; AC2 = 0.870, 90% CI: 0.768-0.972). CONCLUSION The previously published video clip library and our novel surgical difficulty grading system should serve as a universal objective tool to assess surgical difficulty in LC.

Abstract
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.

Abstract
BACKGROUND The aim of this study was to assess whether laparoscopic appendectomy (LA) for complicated appendicitis (CA) effectively reduces the incidence of postoperative complications and improves various measurements of postoperative recovery in adults compared with open appendectomy (OA). METHODS This single-center, randomized controlled trial was performed in the Nagoya Daini Red Cross Hospital. Patients diagnosed as having CA with peritonitis or abscess formation were eligible to participate and were randomly assigned to an LA group or an OA group. The primary study outcome was development of infectious complications, especially surgical site infection (SSI), within 30 days of surgery. RESULTS Between October 2008 and August 2014, 81 patients were enrolled and randomly assigned with a 1:1 allocation ratio (42, LA; 39, OA). All were eligible for study of the primary endpoint. Groups were well balanced in terms of patient characteristics and preoperative levels of C-reactive protein. SSI occurred in 14 LA group patients (33.3 %) and in 10 OA group patients (25.6 %) (OR 1.450, 95 % CI 0.553-3.800; p = 0.476). Overall, the rate of postoperative complications, including incisional or organ/space SSI and stump leakage, did not differ significantly between groups. No significant differences between groups were found in hospital stay, duration of drainage, analgesic use, or parameters for postoperative recovery except days to walking. CONCLUSION These results suggested that LA for CA is safe and feasible, while the distinguishing benefit of LA was not validated in this clinical trial.

Abstract
We retrospectively reviewed 500 cases who were implanted with subcutaneous central venous port(CV port)in our institution from Jan. 2007 to Nov. 2011, to investigate the complications arising after CV port implantation. The purpose of CV port implantation was chemotherapy access in 279 cases and home parenteral nutrition in 221 cases. The primary diseases were malignancy in 441 cases(colorectal cancer 252 cases, gastric cancer 54 cases, etc.)and benign diseases in 59 cases. Seven patients(1. 4%)had complications at implantation(pneumothorax 6 cases, catheter migration 1 case). Forty-three patients(8. 6%)had complications after port implantation. Among them, 18 suffered port infection, 10 had obstruction of the catheter system, 4 developed skin ulceration, 4 developed port rotation, 3 had venous thrombosis, and 3 developed catheter migration. The cumulative patency rates after 1, 2, and 3 years were 90. 7%, 81. 2%, and 74. 6%, respectively. Complications after port implantation were more frequently developed in home parenteral nutrition than in chemotherapy.

Abstract
BACKGROUND Little information has been available concerning the safety of laparoscopic resection of obstructive colorectal cancer after transanal endoscopic tube decompression (TETD). The aim of this study was to assess the short- and long-term outcomes of laparoscopic surgery following TETD for such advanced colorectal cancer. METHODS A retrospective review was performed of 40 patients with obstructive left colorectal cancer whose distended bowels were treated with TETD before laparoscopic surgery, between January 2001 and March 2011 (TETD group). The elective surgery resulted in potentially curative resection of the tumor in all cases. Their clinical records were compared to those of 80 matched controls with nonobstructive left colorectal cancer resected laparoscopically during the same period (control group). RESULTS Operative time, blood loss, and the rate of conversion to laparotomy were comparable between the two groups. There were no significant between-group differences in morbidity rates. Five-year overall survival rates in the TETD and control groups were 71.9 and 75.4%, respectively, with no statistical difference. Disease-free survival rates after 5 years were also similar (TETD group, 64.5% vs. control group, 66.3%). There were no significant differences between the two groups in recurrence rates and patterns. CONCLUSION These results suggest that laparoscopic surgery following TETD is clinically and oncologically safe and could be a treatment of choice for obstructive left colorectal cancer.

Abstract
PURPOSE Three years have passed since the publication of the Tokyo Guidelines for the management of acute cholangitis and cholecystitis, and we believe that the time has come to assess their validity. METHODS In this study, we validated the diagnostic accuracy of these criteria in 74 patients with an initial diagnosis of acute cholangitis and 81 patients with an initial diagnosis of acute cholecystitis. We also statistically compared the accuracy of the diagnosis made based on the Tokyo Guidelines with that based on the presence of Charcot's triad for acute cholangitis and Murphy's sign for acute cholecystitis with use of the sign test to assess differences. RESULTS The results revealed that the diagnostic sensitivity and specificity of the Tokyo Guidelines for suspected or definitive acute cholangitis were 72.1 and 38.5%, respectively, and the corresponding values for definitive cholangitis alone were 63.9 and 69.2%, respectively. For definitive acute cholecystitis, the diagnostic sensitivity and specificity of the Tokyo Guidelines were 84.9 and 50.0%, respectively. The accuracy of diagnosis based on the Tokyo Guidelines was significantly higher than that based on the presence of Charcot's triad (acute cholangitis, p < 0.001 by the sign test) or Murphy's sign (acute cholecystitis, p < 0.001 by the sign test). CONCLUSIONS It was therefore concluded that the Tokyo Guidelines should be used more widely for the diagnosis of acute cholangitis and cholecystitis in the twenty-first century. Hereafter, various efforts should be made to improve the sensitivity and specificity of the diagnostic criterion of the Tokyo Guidelines.

Abstract
We performed breast reconstruction surgery with mastectomy after neoadjuvant chemotherapy(NAC)for a patient with NAC indication desiring breast conservation. The case was a 34-year-old single woman. In March, 2007, she was aware of a lump in her left breast and visited our hospital. The diagnosis was solid-tubular carcinoma 3 cm in diameter from close examination. We performed preoperative chemotherapy with EC(epirubicin 90 mg/m(2), cyclophosphamide 600 mg/m(2))x4, followed by 3w-paclitaxel 175 mg/m(2)x4, and then performed mastectomy with axillary dissection and breast reconstruction surgery using the flap of latissimus dorsi at the same time. Pathologically, pCR was provided. We thought that there are many advantages to both treatment of breast cancer and the cosmetic characteristics. The patient was very satisfied. But further cumulative examinations are awaited because there is not much evidence at present.

Abstract
Although carbon monoxide (CO) has been reported to protect against hepatobiliary dysfunction, mechanisms for its actions remain unknown. This study aimed to examine actions of physiologically relevant concentrations of CO on biliary excretion. The effects of transportal administration of CO on bile output and constituents were examined in perfused rat livers. In livers of fed rats, CO regulated bile output biphasically in a dose-dependent manner; transportal administration of CO at 4 micro mol/L stimulated bile output by 10%. Under these circumstances, CO increased paracellular junctional permeability and consequently decreased biliary excretion of bile salts. Choleresis elicited by 4 micro mol/L CO coincided with significant increases in biliary excretion of bilirubin-IXalpha and glutathione. The CO-induced choleresis occurred independently of cyclic GMP, coincided with elevated excretion of K(+) and HCO(3)(-), and was abolished by tetraethylammonium, suggesting stimulatory effects of the gas on potassium channels. CO-mediated choleresis and increased excretion of organic anions appeared to be mediated by mrp2, because Eisai hyperbilirubinemia rats, which genetically lack the transporter, did not exhibit choleresis upon the CO administration. These results suggest that CO stimulates mrp2-dependent excretion of bilirubin-IXalpha through mechanisms involving potassium channels, serving as a cooperator standing behind the heme oxygenase reaction to facilitate hepatic heme detoxification.

Abstract
This study aimed to investigate the roles of endothelin (ET) receptors in biliary dysfunction and cell injury in postischemic livers. Rat livers perfused with oxygenated Krebs-Henseleit solution were exposed to reoxygenation following 20-minute hypoxia. The anoxic perfusion decreased bile output and reduced cyclic guanosine monophosphate (cGMP) contents, an index of nitric oxide (NO) generation. Upon reoxygenation, the decreased bile was not fully recovered, and the resistance increased biphasically: an early transient spike accompanied by an elevated release of ET-1 and a rise accompanied by a cGMP elevation in the later period. The initial vasoconstriction appeared to be mediated by both ET(A) and ET(B) receptors, as judged by inhibitory effects of their antagonists, BQ-485 and BQ-788, respectively, while the late elevation of the resistance was not attenuated by these reagents, but rather enhanced by the ET(B) blockade. The BQ-788 treatment attenuated the reoxygenation-induced cGMP elevation and induced bile acid-dependent choleresis. However, such a change upon the ET(B) blockade coincided with dissociation of a recovery of phospholipids and aggravation of cell injury. The BQ-788-elicited deterioration of reoxygenation-elicited changes was attenuated by NO supplement with S-nitroso-N-acetyl penicillamine. N(omega)-Nitro-L-arginine methyl ester, an NO synthase inhibitor, mimicked biliary changes elicited by the ET(B) blockade but without causing notable cell injury. Under these circumstances, coadministration of clotrimazole, an inhibitor of cytochrome P450 mono-oxygenases, elicited the injury comparable with that observed under the ET(B) blockade. These results suggest that ET(B)-mediated signaling limits excessive bile acid excretion and plays a protective role against reoxygenation injury through mechanisms involving both NO-dependent and -independent processes.

Abstract
BACKGROUND AND AIMS Liver is a major organ for heme detoxification under disease conditions, but its self-protective mechanisms against the toxicity are unknown. This study aimed to examine roles of carbon monoxide (CO), the gaseous product of heme oxygenase (HO), in ameliorating hepatobiliary dysfunction during catabolism of heme molecules in endotoxemic livers. METHODS Vascular resistance and biliary flux of bilirubin-IXalpha, an index of HO-derived CO generation, were monitored in perfused livers of endotoxemic rats. Livers were perfused with HbO(2), which captures nitric oxide (NO) and CO, or metHb, a reagent trapping NO but not CO. RESULTS In endotoxin-pretreated livers where inducible NO synthase and HO-1 overproduced NO and CO, HbO(2) caused marked vasoconstriction and cholestasis. These changes were not reproduced by the NO synthase inhibitor aminoguanidine alone, but by coadministration of zinc protoporphyrin-IX, an HO inhibitor. CO supplementation attenuated the events caused by aminoguanidine plus zinc protoporphyrin-IX, suggesting that simultaneous elimination of these vasorelaxing gases accounts for a mechanism for HbO(2)-induced changes. This concept was supported by observation that metHb did not cause any cholestasis; the reagent captures NO but triggers CO overproduction through rapid degradation of the heme by HO-1. CONCLUSIONS These results suggest protective roles of CO against hepatobiliary dysfunction caused by heme overloading under stress conditions.
