    Abstract Introduction Incidental discovery of gallbladder cancer (GBC) on postoperative histopathology or intra-operative suspicion is becoming increasingly frequent since laparoscopic cholecystectomy became the standard of care for gallstone disease. Incidental GBC (IGBC) portends a better survival than primarily detected GBC. Various factors affect the outcome of re-resection with the timing of re-intervention an important determinant of survival. Methods All patients of IGBC who underwent curative resection from January 2009 to December 2018 were considered for analysis. Details of demographic profile, index surgery, and operative findings on re-resection, histopathology and follow-up were retrieved from the prospectively maintained database. Patients were evaluated in three groups based on the interval between index cholecystectomy and re-resection: Early (<4 weeks), Intermediate (4-12 weeks) and Late (>12 weeks), using appropriate statistical tests. Results Ninety-one patients were admitted with IGBC during the study period of which 48 underwent re-resection with curative intent. The median age of presentation was 55 years (31-77 years). The median duration of follow-up was 40.6 months (Range: 1.2-130.6 months). Overall and disease-free survival among the above-mentioned three groups was the best in the early group (104 and 102 months) as compared to the intermediate (84 and 83 months) and late groups (75 and 73 months), though the difference failed to achieve statistical significance (p=0.588 and 0.581). On univariate analysis, factors associated with poor outcome were node metastasis, need for common bile duct (CBD) excision and high-grade tumor. However, on multivariate analysis, poor differentiation was the only independent factor affecting survival. Conclusion Early surgery, preferably within four weeks, possibly entails better survival in incidentally detected GBC. The grade of a tumor, however, is the most important determinant of survival in IGBC.

    Abstract The extrahepatic biliary apparatus is a rare site for neuroendocrine tumours. A 13-year-old child presented with cholestatic symptoms of jaundice and pruritus with soft hepatomegaly and mild ascites. Magnetic resonance imaging and endoscopic ultrasound revealed a mid-common bile duct mass, and dilated intrahepatic biliary system. An en-bloc resection of the extrahepatic biliary apparatus, showed malignant cells disposed in lobules in a desmoplastic stroma with intramural invasion, staining positive for cytokeratin, chromogranin, synaptophysin and negative for CD56. At 3 months post-resection, whole body positron emission tomography scan was normal with no recurrence at 24 months.

    Abstract Introduction: Ampullary adenocarcinoma is a rare neoplasm often treated by the complex Whipple's procedure. Several histological factors predict poor prognosis including pancreatobiliary morphology, presence of lymphovascular, perineural invasion and local or distant metastasis. Systemic therapy with gemcitabine, 5-fluorouracil regimens are given with variable benefits. Immunotherapy checkpoint inhibitors have shown beneficial anti-tumor effects in several carcinomas, the most remarkable being in non-small cell lung cancer. Administration of these novel drugs is based on immunohistochemical expression (which may or may not be indicative of response to therapy) along with meticulous decision making by the multidisciplinary team. Immunohistochemistry (IHC) is an effective means of immune marker demonstration and has been used in various tumor types for predictive and prognostic purposes.
    Methods: PD-L1 IHC (clone E1L3N) was applied in 101 cases of ampullary adenocarcinoma. Tumor infiltrating lymphocytes were also evaluated. The immunoreactivity was assessed and categorized into following staining thresholds: <1%, <5%, <10% and ≥10% for tumor cells (membranous and/or cytoplasmic staining pattern), and 5% and 10% cut-offs for immune cells.
    Results: We found that at a 10% cut-off, 73.3% (74/101) patients were men (
    Conclusion: In the context of ampullary adenocarcinoma, this study highlights the positivity observed with the PD-L1 IHC clone E1L3N at different thresholds, with the particularly stronger associations being evident at a 10% cut-off.

    Abstract Sickle cell anemia (SCA) is an autosomal recessive disorder caused by a mutation in beta globin gene. Hepatobiliary system is affected in 10-40% of patients with SCA and has a multifactorial etiology. The authors present a child with SCA and conjugated hyperbilirubinemia due to biliary obstruction. He underwent endoscopic retrograde cholangiopancreatography (ERCP) and biliary stenting, had complications of post sphincterotomy bleed, retroperitoneal hematoma and post laparoscopic cholecystectomy sepsis with acute sickle hepatic crisis. He was managed successfully and is doing well on follow-up. Here authors discuss a stepwise approach in management of jaundice in a patient with SCA. Patients with SCA are prone to develop vaso-occlusive crisis (VOC) during periods of stress. VOC affects the liver as acute sickle hepatic crisis, acute hepatic sequestration or sickle cell intrahepatic cholestasis and is collectively termed as sickle cell hepatopathy. Hemolysis due to sickling results in cholelithiasis with its associated complications. These patients are vulnerable to viral hepatitis and hemochromatosis due to multiple blood transfusions. There may be a concomitant acute viral hepatitis, drug induced liver injury, Budd-Chiari syndrome or other chronic liver diseases. These conditions have considerable clinical overlap and may coexist, making the evaluation more challenging. Detailed history, examination and investigations are required for differentiation of etiology. Periods of stress must be tackled with proper hydration, oxygen supplementation, maintaining hemoglobin >10 g/dL, and a low hemoglobin S fraction. Patients with SCA and conjugated hyperbilirubinemia are "high-risk" and best managed by a multidisciplinary team. Preventive strategies like timely vaccinations, chelation, etc. must be practised.

    Abstract Introduction Pancreatic fluid collection (PFC) is one of the most frequent complications associated with acute pancreatitis. The route of drainage is guided by the size and site of collection. The present study aims to assess the clinical and technical success of transgastric percutaneous drainage (PCD) for managing retrogastric walled-off pancreatic necrosis (WOPN). Materials and methods A total of 44 patients with acute pancreatitis diagnosed with WOPN who underwent transgastric PCD with ultrasound or CT guidance as part of standard clinical management were included in the study. Patients were observed for improvement in clinical parameters, and treatment outcomes were noted in terms of technical success, clinical success, adverse events, need for additional procedures, hospital stay, and duration of placement of all drains. Data for the internalization of transgastric PCD was also observed in the study. Results Technical success during the drain placement was observed in 93% (n=41) of patients.Internalization of the transgastric drain was attempted in 12 patients and successful in 11 (91%). The median duration of hospital stay from the time of placement of the first PCD until discharge and the median duration of all PCDs placed were higher in patients where the transgastric drain was not internalized as compared to patients where the transgastric drain was internalized. Conclusion In WOPN, transgastric drain placement and successful internalization in any form help in the early resolution of peripancreatic and abdominal collections. It also reduces the time to percutaneous catheter removal, which in turn reduces the morbidity and decreases the need for additional interventions or surgery.

    Abstract Background Postcholecystectomy bile duct injury (BDI) is a management challenge with significant morbidity, mortality, and effects on long-term quality of life. Early referral to a specialized hepatobiliary center and appropriate early management are crucial to improving outcomes and overall quality of life. In this retrospective analysis, we examined patients who were managed at our center over the past 10 years and proposed a triage and management algorithm for BDI in acute settings. Methods Patients referred to our center with BDI from January 2011 to December 2020 were reviewed retrospectively. The primary objective of initial management is to control sepsis and minimize BDI-related morbidity and mortality. All the patients were resuscitated with intravenous fluid, antibiotics (preferably culture-based), correction of electrolyte deficiencies, and organ support if required. A triage module and management algorithm were framed based on our experience. All the patients were triaged based on the presence or absence of bile leaks. Each group was further subdivided into red, yellow, and green zones (depending on the presence of sepsis, organ failure, and associated injuries), and the results were analyzed as per the proposed algorithm. Results One hundred twenty-eight patients with acute BDI were referred to us during the study period, and 116 patients had BDI with a bile leak and 12 patients were without a bile leak. Out of bile leak patients, 106 patients (91.38%) had sepsis with or without organ failure (red and yellow zone) and required invasive intervention in the form of PCD insertion (n=99, 85.34%) and/or laparotomy, lavage, and drainage (n=7, 6.03%). Another 10 patients (8.62%) had controlled external biliary fistula (green zone), of which four were managed with antibiotics, four underwent endoscopic retrograde cholangiopancreatography stenting, and only two (1.7%) patients could undergo Roux-en-Y hepaticojejunostomy upfront due to late referral. Among patients with BDI without bile leaks, nine (75%) had cholangitis (red and yellow zones). Out of these, five required PTBD along with antibiotics and four were managed with antibiotics alone. Only three (25%) patients in this group could undergo definitive repair without any restriction on the timing of referral and were sepsis-free at presentation (green zone). A total of nine patients had a vascular injury, and four of them required digital subtraction angiography and coil embolization. There were three (2.34%) mortalities; all were in the red zone of rest and had successful initial management. In total, five patients were managed with early repair in the acute setting, and the rest underwent definitive intervention at subsequent admissions after being converted to green zone patients with initial management. Conclusion The presented categorization, triaging, and management algorithm provides optimum insight to understand the severity, simplify these complex scenarios, expedite the decision-making process, and thus enhance patient outcomes in early acute settings following BDI.

    Abstract Background: The genetic landscape of intestinal (INT) and pancreatobiliary (PB) type ampullary cancer (AC) has been evolving with distinct as well as overlapping molecular profiles.
    Methods: We performed whole-exome sequencing in 37 cases of AC to identify the targetable molecular profiles of INT and PB tumors. Paired tumor-normal sequencing was performed on the HiSeq 2500 Illumina platform.
    Results: There were 22 INT, 13 PB, and two cases of mixed differentiation of AC that exhibited a total of 1,263 somatic variants in 112 genes (2-257 variants/case) with 183 somatic deleterious variants. INT showed variations in 78 genes (1-31/case), while PB showed variations in 51 genes (1-29/case). Targetable mutations involving one or more major pathways were found in 86.5% of all ACs. Mutations in APC, CTNNB1, SMAD4, KMT2, EPHA, ERBB, and Notch genes were more frequent in INT tumors, while chromatin remodeling complex mutations were frequent in PB tumors. In the major signaling pathways, the phosphoinositide 3-kinase (PI3)/AKT and RAS/mitogen-activated protein kinase (MAPK) pathways were significantly mutated in 70% of cases (82% INT, 46% PB, p = .023), with PI3/AKT mutation being more frequent in INT and RAS/MAPK in PB tumors. Tumor mutation burden was low in both differentiation types, with 1.6/Mb in INT and 0.8/Mb in PB types (p =.217).
    Conclusions: The exome data suggest that INT types are genetically more unstable than PB and involve mutations in tumor suppressors, oncogenes, transcription factors, and chromatin remodeling genes. The spectra of the genetic profiles of INT and PB types suggested primary targeting of PI3/AKT in INT and RAS/RAF and PI3/AKT pathways in PB carcinomas.

    Abstract Background: Patterns of failure following definitive CRT (dCRT) are different as compared to neoadjuvant chemoradiotherapy (NACRT) with increased locoregional failures documented with dCRT.
    Aim: To document failure patterns in patients with esophageal carcinoma treated with neoadjuvant and definitive intent radiation strategies.
    Methods: Subjects were 123 patients treated with two chemoradiotherapy strategies. Group 1 (n = 99) underwent dose escalated definitive chemoradiotherapy (dCRT), Group 2 (n = 24) received neoadjuvant chemoradiotherapy (NACRT) followed by surgery. Cumulative incidence of locoregional failure (LRF), local failure (LF), regional lymph node failure (RLNF), and distant metastasis (DM) were computed; differences between the groups was evaluated using log rank test. Univariable and multivariable predictors of failure were identified using Cox regression analysis.
    Results: Cumulative LRF: 64% in Group 1 vs 35% in Group 2 (P = .050). Cumulative LF: 59% in Group 1 vs 12% in Group 2 (P = .000). Cumulative RLNF: 30% in Group 1 vs 24% in Group 2 (P = .592). Most common RLNF: mediastinum for both groups (6% vs 12.5%, respectively). Distant metastasis: 40.4% Group 1 vs 17% Group 2 (P = .129), predominantly lung (Group 1, 5%), and nonregional nodes (Group 2, 8.3%). Univariate analysis identified age ≤50, absence of concurrent chemotherapy, dose ≤50 Gy, and incomplete radiotherapy to predict higher odds of LRF and DM for Group 1; absence of comorbidities predicted for lower odds of LRF for Group 2. Age ≤50 predicted for higher odds of RNLR for Group 1, while absence of comorbidities predicted for lower odds of RNLR in Group 2. Multivariate analysis identified age ≤50, incomplete radiotherapy, and absence of concurrent chemotherapy to predict higher odds of LRF for Group 1. Age ≤50, absence of concurrent chemotherapy predicted higher odds of DM for Group 1. Absence of comorbidity predicted lower odds of LRF in Group 2.
    Conclusion: LRF is common in both groups, with LF being predominant in dCRT as opposed to RNLF in NACRT. Age ≤50, absence of concurrent chemotherapy is a predictor of LRF and DM in dCRT.

    Abstract Background: Ampullary cancer may occur as a component of hereditary cancer syndromes. Mutations in inherited cancer susceptibility genes play a therapeutic role and its knowledge in ampullary cancer is lacking.
    Methods: Thirty-seven cases of ampullary carcinoma were subjected to tumor-normal whole exome sequencing with mean coverage of 100X (blood) and 200X (tumor). Data were analyzed and correlated with intestinal and pancreatobiliary differentiation.
    Results: There were 22 intestinal, 13 pancreatobiliary and 2 cases of mixed differentiation. One hundred and forty-three germline variations with at least >1 pathogenic germline variants (PGVs) across 83 genes were found in 36 of 37 patients. Twelve genes (14.5 %) showed >3, 20 genes (24.1 %) showed two and 51 genes (61.4 %) showed one PGVs. Intestinal differentiation showed higher PGVs (117 variants, 73 genes) than pancreatobiliary differentiation (85 variants, 62 genes). PGVs in ERCC5, MEN1, MSH3, CHEK1, TP53, APC, FANCA, ERBB2, BRCA1, BRCA2, RTEL1, HNF1A and PTCH1 were seen in >50 % of cases. Nine genes harbored somatic second hits in 14 cases. PGVs in DNA damage-repair, homologous recombination repair, TP53 transcriptional regulation, DNA double stranded breaks, cell cycle and nucleotide excision repair genes were seen in all cases of intestinal and pancreatobiliary differentiation, while DNA mismatch repair genes were found in 81.8 % of intestinal and 84.6 % of pancreatobiliary cancers. Functional pathway analysis showed that DNA damage-repair, double stranded break repair, mismatch repair, homologous recombination repair and TP53 transcriptional regulation genes were altered in both while nucleotide-excision repair was significantly mutated in intestinal type and cell-cycle genes in pancreatobiliary type (p < 0.05).
    Conclusion: This study reports spectrum of PGVs in intestinal and pancreatobiliary differentiation of ampullary carcinoma at higher frequency through whole exome sequencing. PGVs were most frequently found in DNA repair genes. Detecting PGVs through tumor-normal sequencing may identify therapeutically actionable and double-hit mutations that can guide towards appropriate management.

    Abstract Objectives: The standard of care for resectable gastric cancers (GCs) includes perioperative chemotherapy (CT) or postoperative chemo/chemoradiotherapy (CRT) strategies. Poor treatment compliance postsurgery suggests that intensified surgical adjuvant treatment is more likely deliverable preceding surgery and, therefore, the safety and efficacy of perioperative cisplatin-capecitabine (CX) with preoperative chemoradiation (preopCRT) were ascertained.
    Materials and methods: Between January 2017 and December 2018, 28 potentially resectable locally advanced GC patients were offered neoadjuvant CT-2 cycles of CX at 3-weekly intervals, followed by preopCRT 45 Gy/25 fractions/5 weeks and concurrent capecitabine, followed by surgical resection and 3 adjuvant cycles of CX.
    Results: Neoadjuvant CT was commenced in 28 patients (100%), preopCRT in 18 patients (64%), and surgery performed in 13 patients (46%). At each treatment step, decreasing patient numbers were due mainly to disease progression (12 [43%]) or other reasons, including (3 [11%]) from treatment-related toxicity. The R0 resection rate was 92% (12/13); a median of 18 nodes was obtained after D2 nodal clearance in 92% (12/13). There were 20%/4%/4% grade 3/4/5 toxicities. The median radiotherapy dose/duration was 45 Gy/5.4 weeks. Adjuvant CT was started in 11 patients (39%) and the third cycle was received by 7 patients (25%). No tumor (ypT0N0) was noted in 23% of the operated patients (3/13), or 11% of the intention-to-treat population (3/28). The median, 1-year, and 2-year survivals were 12 months, 53%, and 32%, respectively.
    Conclusions: Intensified preoperative treatment is doable in relatively unselected advanced GC patients in real-world settings of a public-sector hospital from a low-middle-income country. Disease progression during preoperative therapy allows patients destined for early clinical evidence of disease dissemination to avoid futile surgery, as opposed to a surgery-first strategy, without an overt increase in surgical morbidity or mortality, with encouraging R0 resection rates.
