Background: The role of radiotherapy in the adjuvant treatment of gastric cancer (GC) remains to be elucidated. This study aimed to assess the additional benefit of radiotherapy in the adjuvant treatment of GC.

Materials and methods: In this retrospective cohort study, we included 230 gastric adenocarcinoma patients who underwent D2 dissection between January 2004 and December 2019. Patients without R0 resection, who underwent metastasectomy at surgery, and treated with the neoadjuvant treatment were excluded. The co-primary endpoints were overall survival (OS) and disease-free survival (DFS). The secondary endpoints were the locoregional and distant metastasis risk and adverse events (AEs) leading to treatment discontinuation.

Results: One hundred and sixty-six and 64 patients were included in the chemoradiotherapy (CRT) and chemotherapy (ChT) arms, respectively. The median OS was 135.8 months [interquartile range (IQR): 99.4-172.2] and 97 months (IQR: 59.7-134.3) in the CRT and the ChT arms, respectively. No statistical significance was observed between the arms in OS (p = 0.3). Locoregional or distant recurrence rates were similar in each group. AEs leading to treatment discontinuation were higher in the CRT arm than in the ChT arm (13.2 vs 9.3%), and the difference between the arms was not statistically significant (p = 0.4).

Conclusion: In this real-life study, we established that there was no additional benefit of RT in GC patients who underwent D2 dissection.

Aim and objective: According to the literature, gastrointestinal (GI) involvement may have a remarkable influence on the course of coronavirus disease-2019 (COVID-19). Our aim with this article is to appraise clinical characteristics and presumptive biological mechanisms of digestive tract involvement of COVID-19.

Background: In this review article, the English language literature was reviewed by using PubMed and MEDLINE databases, up to February 2021.

Review results: The patients with GI involvement are generally presented with diarrhea, nausea/vomiting, anorexia, abdominal pain, and rarely GI bleeding. However, frequencies of these manifestations are diverse in studies published so far, depending on the countries where the studies were conducted, characteristics of the study populations, and methodological differences. Several studies proved that this novel coronavirus gets into the enterocytes by attaching to angiotensin-converting enzyme 2 receptor. Some of them have shown a direct viral invasion and replication of the virus within enterocytes. Along with detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients' fecal materials, all these results explicitly indicate that the virus has the capability to invade the GI system. These findings may represent a potential risk indicator for fecal-oral spread of the virus. Although pathophysiology of COVID-19 associated GI manifestations remains elusive, direct viral damage, dysfunction in renin-angiotensin-aldosterone system, effects of gut-lung axis, and GI tract microbiome dysbiosis have been proposed as culprit mechanisms of the GI symptoms and inflammatory response.

Conclusion: The patients with COVID-19 can be presented with diverse clinical manifestations including the GI symptoms. Understanding the actual impact of the virus on the GI tract depends on uncovering the pathophysiology of COVID-19.

Clinical significance: GI involvement of COVID-19 appears to be crucial not only for its clinical consequences but also for its impacts on public health and prevention.

Background: Wilson's disease (WD) is a rare disorder of copper toxicosis. Hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome is even rarer. The coexistence of these two disorders and their clinical implications are not yet reported. We report on a child who succumbed to death due to liver disease caused by both disorders, documenting their disease-causing mutations and highlighting the lessons learnt out of this case.

Case description: A child who was diagnosed to have WD soon after birth due to known parental heterozygosity was later found to have developmental delay, seizures, and hyperammonemia. Subsequent evaluation confirmed hyperornithinemia-hyperammonamia-homocitrullinuria (HHH) syndrome as a comorbidity. Though this child was commenced on medical treatment for both the metabolic diseases since early life, his liver disease was rapidly progressive requiring a liver transplant (LTx) at 6-years. He died in the posttransplant period possibly due to sepsis and hidden metabolic consequences.

Conclusion: This case highlights that co-occurrence of WD and HHH syndrome would cause progressive liver disease despite medical treatment. Hence, the close clinical follow-up and early LTx would be warranted.

Introduction: Gastrointestinal (GI) tract is the most common site of extranodal lymphoma accounting for 30-40% of the cases. In Western countries, stomach is the most common site of GI lymphoma, whereas in the Middle East and Mediterranean countries, small intestine is commonly involved. Studies about primary intestinal lymphoma (PIL) are heterogeneous in anatomical distribution, presentation, and histological subtypes. The present study was aimed at studying the anatomical distribution, histological subtypes, and clinical characteristics at tertiary care centers.

Materials and methods: The present study was retrospective, conducted between 2006 and 2020. Patient's data were collected from institutional medical records. PIL was diagnosed by Lewin's criteria. After histological diagnosis, PIL was classified as per the World Health Organization (WHO) criteria and staging was done according to the Ann Arbor classification as modified by Musshoff.

Results: A total of 941 lymphoma cases were diagnosed during the study period between 2006 and 2020 consisting of 238 Hodgkin's lymphoma and 703 non-Hodgkin's lymphoma (NHL) cases. PIL constituted 5.8% of all lymphoma cases (55 out of 941) and 50.9% (55 of 108) of all primary GI lymphoma. Median age at diagnosis was 44 years and comprised predominantly males (85.45%). Diffuse large B-cell lymphoma (DLBCL) and mucosa-associated lymphoid tissue (MALT) lymphoma were the most common histological subtype (78%) seen. Two patients with primary Hodgkin's lymphoma involving the intestine were seen. T-cell lymphoma was seen in three (5.4%) patients. Ileocecal region was the most common site involved (27%). The common presenting complaints were intestinal obstruction (40%) requiring surgical resection and abdominal pain (32%). Majority of the patients presented in the early stages (I and II).

Conclusion: Our study demonstrates the pattern of distribution and various histological subtypes of PIL including the rare variants like primary intestinal Hodgkin's lymphoma. Relatively more number of patients presented with intestinal obstruction requiring surgery in comparison with other studies.

Right hepatic artery (RHA) syndrome is a well-recognized, though an uncommon cause of benign bile duct stricture, potentially simulating malignancy. Albeit the latter was not the case in this unique clinical report after cholangitis resolution and clearance of biliary sludge and debris, high-quality direct cholangioscopy (DC) illustration of the RHA overriding the proximal common bile duct with well visible arterial pulsation has not yet been reported before. Beyond its potential visual informativeness, this uncommon cholangioscopic documentation may provide key didactic advances in terms of intraductal visualization of the anatomy of the biliary tree.

Background: Metastasis to lymph nodes is a bad prognostic factor in patients with gallbladder carcinoma who undergo radical cholecystectomy. During the past decade, studies have brought focus on lymph node ratio (LNR) as an additional valuable prognostic factor in these cases.Our research studied the factors that predicted the recurrence of disease and survival of patients with gallbladder carcinoma who were treated with surgical resection, concentrating especially on the lymph nodal status as a prognostic factor and LNR in node-positive T1-T3 cases.

Methods: In our hospital, Mahavir Cancer Institute and Research Centre, we reviewed retrospective data, from 2009 to 2014, of 60 patients who had undergone radical cholecystectomy for gallbladder carcinoma. We staged the patients as per the AJCC eight edition. Predictive factors that affect disease-free survival (DFS), like age, gender, postoperative complications, lymphovascular invasion (LVI) and perineural invasion (PVI), lymph node dissection, differentiation, T stage, N stage, number of lymph nodes involved, and LNR, were examined statistically.

Results: Lymph nodal involvement was found to be a principal predictive factor in cases in whom radical cholecystectomy was done. The number of lymph nodes dissected determined the prognosis in N0 cases. LNR was a strong prognostic factor for DFS in cases of curatively resected gallbladder cancer.

Conclusion: LNR is a strong predictive factor in radically resected gallbladder carcinoma cases.

Background: Exchange transfusion in newborns is recommended as emergency management of hyperbilirubinemia to prevent bilirubin encephalopathy and kernicterus.

Aim: This study aimed to determine the frequency and document common side effects of exchange transfusion and outcomes of newborns requiring exchange transfusion.

Materials and methods: This prospective study was done in the Neonatal Intensive Care Unit (NICU) of Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh, from January 2016 to December 2019. Information was obtained regarding maternal details, newborn demographics, and clinical status. Blood grouping and Rh typing were done for both mothers and newborns. In all newborns, pre-exchange complete blood count, peripheral blood film, Coombs test, reticulocyte count, serum bilirubin and post-exchange serum bilirubin, hemoglobin, random blood sugar, serum electrolyte, and calcium were done. G6PD level was done wherever suspected. Frequency, maternal and neonatal factors, indications, and outcomes were analyzed.

Results: Among 839 admitted cases of unconjugated hyperbilirubinemia, 41 patients (4.9%) required exchange transfusion. Most of the babies were inborn (90.2%). Ninety-five percent of mothers received regular antenatal care; among them, 76.3% had bad obstetric history. Only 36.6% of mothers received anti-D in previous pregnancy. None had sonographic findings of hydrops. The commonest indication was Rh incompatibility (80.5%). Coombs test was positive in 58.5% of cases. Mean pre-exchange TSB was 9.44 ± 6.4, and post-exchange TSB was 4.41 ± 2.59. The commonest adverse events noted were hyperglycemia (51.2%), sepsis (19.5%), anemia requiring top-up transfusion (17.1%), and hypocalcemia (14.6%). There were no catheter-related complications. Bilirubin encephalopathy was present in 4.9% of cases. There was one mortality but not due to the procedure.

Conclusion: Exchange transfusion was required among 4.9% of the admitted newborns with unconjugated hyperbilirubinemia. The common adverse effects were hyperglycemia and sepsis. The commonest indication was Rh incompatibility (80.5%). Overall outcome after exchange transfusion was favorable.

Introduction: Globally, the incidence, as well as mortality, related to hepatocellular carcinoma (HCC) is on the rise, owing to relatively few curative options. Underlying cirrhosis is the most common etiology leading to HCC, but risk factors of cirrhosis show great regional variability. Over the years, there has been a steady development in the diagnostic and therapeutic modalities of HCC, including the availability of a wide range of systemic chemotherapeutic agents. We aim to review the recent advancements in the diagnostic and therapeutic strategies for HCC.

Methodology: The literature search was done using databases PubMed, Cochrane, and Science Direct, and the latest relevant articles were reviewed.

Findings: Screening of HCC is a pivotal step in the early diagnosis of the disease. Current guidelines recommend using ultrasound and alfa fetoprotein but various new biomarkers are under active research that might aid in diagnosing very small tumors, not picked up by the current screening methods. Treatment options are decided based upon the overall performance of the patient and the extent of the disease, as per the Barcelona classification. There are very few options that offer a cure for the disease, ranging from liver resection and transplantation to tumor ablation. Downstaging has proven to have a significant role in the course of the disease. An attempt to control the disease can be made via radiological interventions, such as transarterial chemoembolization, transarterial radioembolization, or radiation therapy. For advanced disease, sorafenib used to be the only option until a couple of years ago. Recently, many other systemic agents have received approval as first-line and second-line therapies for HCC. Genomics is an area of active clinical research as understanding the mutations and genomics involved in the evolution of HCC might lead to a breakthrough therapy.

Introduction: A preferred treatment for cholelithiasis with choledocholithiasis is endoscopic retrograde cholangiopancreaticography (ERCP) followed by laparoscopic cholecystectomy (LC), which can be performed early (within 72 hours) or can be delayed for 6 to 8 weeks. This study is conducted to compare and analyze the outcome of early versus late LC following common bile duct (CBD) clearance by ERCP and determine the optimum timing for performing LC post-ERCP.

Materials and methods: This comparative analysis was conducted at St Joseph Hospital, Ghaziabad, from September 2019 to March 2021 on 89 cases of cholelithiasis with choledocholithiasis. Patients were divided into two groups. Group I (n = 45) patients underwent early LC within 72 hours post-ERCP and group II (n = 44) patients underwent late LC after an interval of 8 weeks. Various preoperative, perioperative, and postoperative clinical parameters like operative difficulty, complications, surgery duration, hospital stay, and conversion to open cholecystectomy were analyzed.

Results: There was no significant difference in demographic and laboratory findings in both groups. Group I patients had significantly shorter hospital stay and less operative difficulty. The duration of surgery was significantly low in group I. There was no significant difference in rate of conversion to open cholecystectomy.

Conclusion: Early LC post-ERCP is associated with short hospital stay and duration of surgery and less operative difficulty and complications. Therefore, we recommend that LC can be safely performed within 48 to 72 hours after ERCP.
