Gallbladder cancer has a poor prognosis, especially in peritoneal carcinomatosis related to perforation of the gallbladder followed by bile spillage. Previously, curative-intent treatment was not considered in carcinomatosis from cancer of the biliary tract. A 72-year-old male was referred to the hospital with a perforated gallbladder cancer. Intraoperatively, the tumor was confined to the gallbladder and liver. We presented a case of intention-to-curative resection of perforated gallbladder cancer followed by intraoperative hyperthermic intraperitoneal chemotherapy.

Caroli syndrome (CS) is characterized by multiple intrahepatic biliary cysts which are continuous with the biliary tract. First case is a 1-year-old, Munchkin cat that presented with icterus. This patient was diagnosed with CS based on imaging and histopathology. With surgery and supportive care, the patient has been well managed. Second case is a 1-year-old, mixed breed dog that presented with anorexia and abdominal distention. This patient was suspected to have CS based on ultrasonography, and died after 7 days. Although unusual, CS could be considered as a differential diagnosis for young animals with hepatic cysts.

Aim: To present an epidemiological and histological perspective of diseases of the gastrointestinal tract (including liver and biliary tract) at the Section of Histopathology, Department of Pathology, AKUH, Karachi, Pakistan. Materials and Methods: All consecutive endoscopic biopsies and resections between October 1 and December 31, 2012 were included. Results: A total of 2,323 cases were included. Carcinoma was overwhelmingly the commonest diagnosis on esophageal biopsies (69.1%); chronic helicobacter gastritis (45.6%) followed by adenocarcinoma (23.5%) were the commonest diagnoses on gastric biopsies; adenocarcinoma (27.3%) followed by ulcerative colitis (13.1%) were the commonest diagnoses on colonic biopsies; acute appendicitis (59.1%) was the commonest diagnosis on appendicectomy specimens; chronic viral hepatitis (44.8%) followed by hepatocellular carcinoma (23.4%) were the commonest diagnoses on liver biopsies; chronic cholecystitis was the commonest diagnosis (over 89%) on cholecystectomy specimens. Conclusions: Squamous cell carcinoma comprised 88.8% of esophageal cancers. About 67% were in the lower third and 56.5% were moderately differentiated; mean ages 49.8 years for females and 55.8 years for males; 66% cases were from South West Pakistan. Over 67% patients with gastric adenocarcinoma were males; mean ages 59 and 44 years in males and females respectively, about 74% gastric carcinomas were poorly differentiated; and 62.2% were located in the antropyloric region. About 63% patients with colorectal adenocarcinoma were males; mean ages 46.1 and 50.5 years for males and females respectively; tumor grade was moderately differentiated in 54%; over 80% were located in the left colon. In 21.2% appendicectomies, no acute inflammation was found. Acute appendicitis was most common in young people. Hepatitis C (66.3%) was more common than hepatitis B (33.7%); about 78% cases of hepatocellular carcinoma occurred in males; females comprised 76.7% patients with chronic cholecystitis; and 77.8% patients with gall bladder carcinoma. All resection specimens showed advanced cancers. Most cancers occurred after the age of 50 years.

Therapeutic endoscopic ultrasonography (EUS) procedures using the forward-viewing convex EUS (FV-EUS) have been reviewed based on the articles reported to date. The earliest reported procedure is the drainage of pancreatic pseudocysts using FV-EUS. However, the study on drainage of pancreatic pseudocysts focused on showing that drainage is possible with FV-EUS rather than leveraging its features. Subsequently, studies describing the characteristics of FV-EUS have been reported. By using FV-EUS in EUS-guided choledochoduodenostomy, double punctures in the gastrointestinal tract can be avoided. In postoperative modified anatomical cases, using the endoscopic function of FV-EUS, procedures such as bile duct drainage from anastomosis, pancreatic duct drainage from the afferent limb, and abscess drainage from the digestive tract have been reported. When a perpendicular puncture to the gastrointestinal tract is required or when there is a need to insert the endoscope deep into the gastrointestinal tract, FV-EUS is considered among the options.

Background/Aims: The optimal length of the uncovered portion of partially covered self-expandable metal stents (PCSEMSs) used in endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) remains unclear. This study investigated the safety and efficacy of PCSEMSs with different uncovered lengths, with a focus on stent migration and time to recurrent biliary obstruction (RBO). Methods: Outcomes of patients undergoing EUS-HGS using PCSEMSs with 5-mm and 20-mm uncovered portions at our institution from January 2016 to December 2021 were compared. Results: Sixty-two patients underwent EUS-HGS using PCSEMS (5/20-mm uncovered portions: 32/30). Stent migration occurred only in the 5-mm group. There were no differences in RBO rates (28.1% vs. 40.0%) or median time to RBO (6.8 vs. 7.1 months) between the two groups. Median overall survival (OS) was longer in the 20-mm group (3.1 vs. 4.9 months, p=0.037) due to the higher number of patients that resumed chemotherapy after EUS-HGS (56.7% vs. 28.1%, p=0.029). Good performance status, absence of hepatic metastases, and chemotherapy after EUS-HGS were independent predictors of longer OS. Conclusions: No migration was observed in patients treated with PCSEMS with 20-mm uncovered portions. Patients treated with PCSEMS with 20-mm uncovered portions performed at least as well as those treated with 5-mm uncovered portions in all material respects.

Several infectious agents are considered to be causes of cancer in human, mainly hepatitis B and C viruses, high-risk human pailloma viruses, Helicobacter pylori, Clonorchis sinensis, and Opisthorchis viverrini. Here we described the evident research and the association between Helicobacter spp. and biliary tract cancer particularly cholangiocarcinoma (CCA). Global epidemiological studies have suggested that Helicobacter spp. are possible risk factors for biliary tract diseases. Molecular studies support a linkage of Helicobacter spp. with CCA development. H. pylori, H. bilis, and H. hepaticus, are found in CCA, but the most common species are H. pylori and H. bilis. The type of CCA are associated with Helicobacter spp. include extrahepatic CCA, and common bile duct cancer. Up to the present, however, the results from different regions, materials and methods, sub-sites of cancer, and controls have not been consistent, thus introducing heterogeneity. Therefore, a comparison between co-Helicobacter spp.-CCA in the countries with low and high incident of CCA is required to settle the question. Furthermore, clarifying variation in the role of Helicobacter species in this CCA, including pathogenesis of CCA through enhanced biliary cell inflammation and proliferation, is necessary.

A 61-year-old male who complained of right upper quadrant pain was referred to the authors for evaluation after his computed tomography suggested biliary adenocarcinoma. The lesion consisted of multiple cysts with papillary mass and peri-ampullay mass. The patient underwent an operation due to a clinical suspicion of biliary cystadenocarcinoma, but the pathology confirmed biliary papillomatosis (BP) after diagnosing intrahepatic papillary neoplasm with high-grade dysplasia and invasive adenocarcinoma with papillary neoplasm from the distal common bile duct to the duodenum. BP is a disease characterized by multiple papillary masses. Its cause has yet to be discovered. It commonly manifests as bile duct dilation but rarely as a ductal cystic change. Under computed tomography or magnetic resonance imaging, both the BP and the cystic neoplasm can show bile duct dilation and a papillary mass, which makes their differential diagnosis difficult. A confirmative diagnosis can be made through a pathologic examination. BP is classified as a benign disease that can become malignant and may recur, though rarely. Its treatment of choice is surgical resection. Laser ablation or photodynamic therapy can be used for unresectable lesions. In the case featured in this paper, biliary papillomatosis was difficult to differentiate from cystic adenocarcinoma due to diffusely scattered multiple large cystic lesions in the liver, and it was histologically confirmed to have become malignant with cystic duct dilation after the operation. This case is reported herein with a literature review.
