Abstract
Gallbladder cancer (GBC) is a biological, anatomical, and clinically distinct subset of biliary tract cancers (BTC), which also include extra- and intra-hepatic cholangiocarcinoma. The advent of next-generation sequencing (NGS) clearly shows that GBC is genetically different from cholangiocarcinoma. Although GBC is a relatively rare cancer, it is highly aggressive and carries a grave prognosis. To date, complete surgical resection remains the only path for cure but is limited to patients with early-stage disease. The majority of the patients are diagnosed at an advanced, inoperable stage when systemic treatment is administered as an attempt to enable surgery or for palliation. Gemcitabine and platinum-based chemotherapies have been the main treatment modality for unresectable, locally advanced, and metastatic gallbladder cancer. However, over the past decade, the treatment paradigm has evolved. These include the introduction of newer chemotherapeutic strategies after progression on frontline chemotherapy, incorporation of targeted therapeutics towards driver mutations of genes including HER2, FGFR, BRAF, as well as approaches to unleash host anti-tumor immunity using immune checkpoint inhibitors. Notably, due to the rarity of BTC in general, most clinical trials included both GBC and cholangiocarcinomas. Here, we provide a review on the pathogenesis of GBC, past and current systemic treatment options focusing specifically on GBC, clinical trials tailored towards its genetic mutations, and emerging treatment strategies based on promising recent clinical studies.

Abstract
Increasing knowledge regarding pancreaticobiliary maljunction (PBM) has led researchers to find that pancreatobiliary reflux (flow of pancreatic juice into the biliary tract) occurs not only in PBM patients but also in individuals with a normal pancreaticobiliary junction (occult pancreatobiliary reflux, OPR). The functional disorders of the sphincter of Oddi have been proposed as a possible cause for OPR. Some studies have found that OPR is a high risk factor for gallbladder cancer. The incidence of choledochal stones is higher in patients with OPR than in those without OPR. In this article, we review the progress in research of OPR.

Abstract
Congenital dilations of the biliary tract are a group of rare conditions, commonly associated with the presence of an abnormality at the junction of the common bile duct and pancreatic duct, which may lead to the reflux of pancreatic juice within the biliary tree. The main clinical symptoms are, abdominal pain, cholangitis and acute pancreatitis, and the most serious complication is malignant degeneration. The treatment of choice is cholecystectomy and complete excision of the bile duct from its bifurcation to its intra-pancreatic segment.

Abstract
OBJECTIVE The objective of this study was to evaluate prognostic predictors for patients with gallbladder cancer (GBC) in a Japanese nationwide data base. SUMMARY BACKGROUND DATA GBC is the most common cancer of the biliary tract in Japan. Differences in the survival rates between Japan and other countries have been noted. METHODS The authors analyzed 4424 patients with GBC in Japan between 1988 and 1997. Staging was determined in accordance with American Joint Committee on Cancer stage. RESULTS Survival is related closely to the surgical stage. Five-year survival rates for stage I, II, III, IVA, and IVB (5th edition) were 83%, 70%, 45%, 23%, and 9%, respectively. These differences were significant (P < 0.0001). The survival rate for patients aged <60 years was significantly better (P < 0.05). The survival rate for patients aged >69 years was significantly worse (P < 0.01). The cholecystectomy plus combined resection of bile duct and/or liver bed resection had an effect on prolonging the survival in stage II or III disease, but extended resection did not. The patients with anomalous pancreaticobiliary ductal junction had a survival advantage over those with cholelithiasis by univariate analysis. However, multivariate analyses indicated that only age, sex, stage, operative procedures were independent prognostic factors. Stage was the strongest covariate; patients diagnosed with stage II, III, IVA, or IVB disease were 2.2, 4.2, 8.1, and 13.6 times, respectively, were more likely to die. CONCLUSIONS Staging is the strongest prognostic factor for GBC, but patient outcomes were also affected by age, sex, and operative procedures. The data do not support any advantage for extended resection. Neither gallstones nor anomalous pancreaticobiliary ductal junction influenced the GBC patient outcome.

Abstract
BACKGROUND AND OBJECTIVES It was proposed that occult pancreaticobiliary reflux (OPBR) was associated with precancerous mucosal changes in the gallbladder, hence the importance of this disorder. There are no published reports investigating the incidence of OPBR in patients operated on for the entire spectrum of benign gallbladder diseases and gallbladder cancer. Our aim was to determine the incidence of OPBR and measure the levels of active pancreatic enzymes (amylase and lipase) in gallbladder bile of patients undergoing cholecystectomy for benign and malignant gallbladder diseases. METHODS One hundred eight patients with normal pancreaticobiliary junction evidenced by operative cholangiography were included in the study. RESULTS According to gallbladder bile amylase and lipase levels, 84.2% and 89% patients respectively had OPBR. OPBR was present in all gallbladder cancer patients; in these patients the biliary levels of amylase and lipase were significantly higher than the levels found in patients with benign gallbladder pathology (P < 0.0001). CONCLUSIONS OPBR could lead to inflammatory changes of the biliary epithelium and progress towards the development of precancerous mucosal changes and gallbladder cancer. The reason why such high levels of pancreatic enzymes are regurgitated into the biliary tree of patients with gallbladder cancer should be clarified.

Abstract
BACKGROUND AND AIM To highlight the epidemiological, clinical, and pathological features of gallbladder cancer in Jordan as a model for the Middle East. Only scattered reports are available from this region. METHODS The histopathological reports and the hospital records for all cholecystectomies performed at Princess Basma Teaching Hospital between 1994-2000 were retrospectively reviewed to identify all patients with gallbladder carcinoma. All the histological slides for the cancer group were reviewed and reclassified by a single pathologist. RESULTS Of 4502 cholecystectomies performed, 33 cases (0.73%) of gallbladder carcinoma were found. The mean age was 61.4 years (range 39-80 years). The male : female ratio was 1 : 3.7. Biliary colic and/or acute cholecystitis were the main presentations. Gallstones were present in 88% (29/33) of the patients. The spectrum of histological subtypes was similar to other series. Only three cases were diagnosed preoperatively, making the incidence of incidental gallbladder cancer 0.66% (30/4502). Simple cholecystectomy was performed for 13 patients. The remaining 20 patients underwent cholecystectomy and portal lymphadenectomy with (five cases) or without (15 cases) extrahepatic resection of the bile ducts. The mean follow up was 22 months (SD +/- 18.95 months; range 1-96 months). The 2-year survival rates for stages I, II, III, and IV were 100%, 42.9%, 10.8%, and 0%, respectively (P = 0.0013). CONCLUSIONS The importance of a high index of suspicion when dealing with cholelithiasis in elderly patients, particularly with large sized stones, cannot be over-emphasized. Proper gross inspection in the theater should be a routine procedure performed by all surgeons. Routine ultrasound for suspected gallbladder stones should always be performed under the supervision of senior radiologists.

Abstract
BACKGROUND Papillary carcinoma of the extrahepatic bile duct presents clinically and histologically distinct features relevant to surgical decision-making. STUDY DESIGN Serial sections of 15 specimens of resected papillary carcinoma of the bile duct were histologically examined to determine mode of spread, possibility of multicentric tumor origins, and coincidence with other neoplastic lesions. The presence of anomalous pancreaticobiliary ductal union was also investigated. These characteristics were considered with regard to surgical treatment. RESULTS Three patients displaying pancreaticobiliary maljunction and one of three patients with a long common channel (> or = 8 mm) exhibited multicentric tumors. Eight patients (53%) demonstrated superficial spread along a mean length of 37.8 mm (range, 5 to 67 mm) of bile duct mucosa. Multicentric tumors developed synchronously in 4 patients, while metachronous tumors were identified in three patients displaying tumor histology similar to the primary lesions. Two of these three underwent successful repeated resection. Concomitant neoplastic lesions in the biliary tract were identified as mucosal dysplasia in four patients and cholangiocellular carcinoma of the liver in two. All tumors but one were removed via hepatic lobectomy or pancreatoduodenectomy, or both, resulting in a 5-year survival rate of 60%. CONCLUSIONS Aggressive resection offers clear survival benefits for patients presenting with tumors displaying extensive superficial spread or multicentric origins. Closer attention should be paid to long common channels in relation to carcinogenesis of the bile duct, in addition to pancreaticobiliary maljunction. The risk of secondary tumor development remains, particularly in patients with pancreaticobiliary maljunction even after excision of the tumor-bearing extrahepatic bile duct.

Abstract
During the 16th and 17th centuries, several important discoveries were accomplished by anatomists whose contribution has enlightened the most important anatomic structures of the pancreas. Following the earliest discoveries, researchers of several medical specialities further investigated the ductal pancreatic system. The accessory pancreatic duct with its minor papilla, the main pancreatic duct and the papilla major along with the confluence of the main pancreatic duct with the bile duct and pancreas divisum, have been the objects of interest of several personalities of the medical history. Eponyms in pancreatic anatomy were given to remember some of them, although anatomical misattributions are frequent and controversial. The aim of the authors was to dedicate a small tribute to the researchers who have written, during the last 500 years, important chapters of the medical history and who dedicated their lives to study the pancreatic ducts and their duodenal endings. Furthermore, a brief outlook was dedicated to the impact of anatomic variations and of embryologic anomalies of the pancreatic ducts in our clinical practice and in our actual understanding of duct-related diseases. The authors are confident that the genial curiosity of few extraordinary personalities of the past and the opportunities provided by modern technology continue to play a major role that may finally add wisdom to decision-making in dealing with duct-related biliopancreatic diseases and safety to diagnostic and therapeutic procedures employed.

Abstract
BACKGROUND Anomalous union of the pancreatic and biliary ducts (AUPBD) is characterized by the intersection of these ducts proximal to the sphincter of Oddi. Thus, the relative anatomic relationship between the pancreaticobiliary ductal union and the narrow distal segment of the bile duct, which represents the functional sphincter, on cholangiopancreatograms determines whether the ductal union is normal or anomalous. This study examined whether the length of the common channel or that of the narrow distal segment is more closely associated with AUPBD and defined radiographic criteria for AUPBD. METHODS The length of the common channel and of the narrow distal segment were measured directly on cholangiopancreatograms from 350 patients. RESULTS AUPBD was found in 36 patients (10%). The common channel was significantly longer in patients with AUPBD (p < 0.001), whereas the length of the narrow distal segment was comparable between patients with and without AUPBD (p = 0.38). There was considerable overlap in the range of the length of the common channel between patients with and without AUPBD. CONCLUSIONS The length of the common channel is closely associated with the presence of AUPBD. However, a diagnosis of AUPBD based on the length of the common channel is not reliable. The diagnosis of AUPBD continues to rely on the radiographic criterion of a pancreaticobiliary ductal union located proximal to the narrow distal segment, which represents the sphincter of Oddi.

Abstract
Primary carcinoma of the gallbladder is an uncommon, aggressive malignancy that affects women more frequently than men. Older age groups are most often affected, and coexisting gallstones are present in the vast majority of cases. The symptoms at presentation are vague and are most often related to adjacent organ invasion. Therefore, despite advances in cross-sectional imaging, early-stage tumors are not often encountered. Imaging studies may reveal a mass replacing the normal gallbladder, diffuse or focal thickening of the gallbladder wall, or a polypoid mass within the gallbladder lumen. Adjacent organ invasion, most commonly involving the liver, is typically present at diagnosis, as is biliary obstruction. Periportal and peripancreatic lymphadenopathy, hematogenous metastases, and peritoneal metastases may also be seen. The vast majority of gallbladder carcinomas are adenocarcinomas. Because most patients present with advanced disease, the prognosis is poor, with a reported 5-year survival rate of less than 5% in most large series. The radiologic differential diagnosis includes the more frequently encountered inflammatory conditions of the gallbladder, xanthogranulomatous cholecystitis, adenomyomatosis, other hepatobiliary malignancies, and metastatic disease.

Abstract
BACKGROUND Surgical procedures based on the depth of the primary tumor invasion (pT category) have been proposed in the treatment of gallbladder cancer (GBC). Trocar site metastases have been reported in patients who underwent laparoscopic cholecystectomy (LC) for preoperatively undiagnosed GBC. STUDY DESIGN The aim of this study was to clarify the role of LC as a surgical strategy for GBC. From 1986 to 1998, 56 patients with GBC underwent surgical resection. Survival rates were compared retrospectively according to pT category and use of LC. RESULTS Five-year survival was 91% for pT1 (n = 13), 64% for pT2 (n = 25), 34% for pT3 (n = 14), and 0% for pT4 tumors (n = 4; p<0.0001). LC was performed on 11 patients (4 with pT1, 5 with pT2, and 2 with pT3 tumors). Of the seven patients with pT2 or pT3 tumors, three underwent a second radical operation, three had an open radical operation to which the procedure was converted from LC, and one underwent no additional procedures. For pT1 tumors, one patient died of trocar site metastasis from bile spillage after LC. For pT2 or pT3 tumors, 5-year survival was 63% for radical surgery (n = 35) and 0% for cholecystectomy alone (n = 4; p<0.05). For pT2 or pT3 tumors treated by radical surgery, 5-year survival was 75% for laparoscopic approach (n = 6) and 60% for open surgery (n = 29; not significant). CONCLUSIONS LC may help to establish the diagnosis and to determine the surgical strategy for undiagnosed GBC. It is important to prevent spillage or implantation of malignant cells during LC. For pT2 or pT3 tumors diagnosed laparoscopically, a second or converted open radical surgery is necessary.
