Demographic and clinical profile of patients undergoing colonoscopy at a tertiary care center in Nepal: a retrospective cross-sectional study.

Background: Colonoscopy is widely used as a tool for diagnosis, screening and treatment of various pathologies in the rectum, colon, and terminal ileum. The aim of this study is to evaluate the demographic, clinical, and histological parameters of the records of patients undergoing colonoscopy at a tertiary care hospital in Nepal. Materials and methods: This retrospective cross-sectional study included the hospital records of all patients who underwent colonoscopy from 2015 to 2019 in a tertiary care centre in Nepal. Results: A total of 1255 records were included in the study. The mean and standard deviation of age were 43.8 and 19 years, respectively. Among the total study population, 61.9% were males and 38.1% were females. Common indications for colonoscopy included lower gastrointestinal bleeding (27.7%), altered bowel habit (26.9%) and persistent or recurrent abdominal pain (17.3%). Only 3% of the patients who underwent colonoscopy had inadequate bowel preparation. The overall diagnostic yield of colonoscopy was 57.5%. Findings during colonoscopy included colorectal polyp (19.4%), internal haemorrhoids (8.2%) and colitis (6.5%). Having an age of 50 or more years was significantly associated with the presence of colorectal adenocarcinoma (P=0.017, χ2 test) with an odds ratio of 2.35 (95% CI: 1.14, 4.89). Furthermore, having a female sex was found to be significantly associated with the presence of colorectal adenocarcinoma (P=0.012, χ2 test) with an odds ratio of 2.43 (95% CI: 1.19, 4.97). Conclusion: In the authors' study, a smaller proportion of the colonoscopies was aimed at screening for colorectal carcinoma (CRC), when compared to studies in developed countries. The sex predisposition of CRC in the authors' study is in contrast to the global trend. The authors recommend conducting studies to determine the risk factors and need for CRC screening in the Nepalese population.

Helicobacter pylori Infection among Patients Undergoing Upper Gastrointestinal Endoscopy in a Tertiary Care Center.

Introduction: Helicobacter pylori is a gram-negative gut bacterium associated with dyspepsia, peptic ulcer disease, and gastric cancer, whose prevalence is still common in developing countries. Upper gastrointestinal endoscopy is the gold standard, first-line investigation for evaluating gastrointestinal disorders. The aim of the study was to find out the prevalence of Helicobacter pylori infection among patients undergoing upper gastrointestinal endoscopy in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted in a tertiary health care centre among the patients undergoing upper gastrointestinal endoscopy from 5 January 2020 to 5 January 2023 after obtaining ethical approval from the Institutional Review Committee. Convenience sampling method was used. The point estimate was calculated at a 99% Confidence Interval. Results: Among 1,975 patients, Helicobacter pylori infection was found in 561 (28.41%) (25.79-31.03, 99% Confidence Interval). The indication for upper gastrointestinal endoscopy was mostly dyspepsia 256 (45.68%) followed by abdominal pain 205 (36.54%). The most common endoscopic finding was gastritis 445 (79.32%) followed by hiatal hernia 93 (16.58%). The commonest biopsy finding was chronic active gastritis 478 (85.20%). Conclusions: The prevalence of Helicobacter pylori infection among patients undergoing upper gastrointestinal endoscopy was found to be similar to other studies done in similar settings. The persistence of H. pylori emphasizes the need of continuous research to address ever evolving H. pylori infections and resistance that are developing against available treatment modalities. Keywords: endoscopy; Helicobacter pylori; upper gastrointestinal tract.

Hydatid hepatopleural fistula causing biliothorax: minimally invasive approach with ERCP stent placement and chest tube drainage: a case report.

Introduction and importance: Biliothorax and hydatid bilio-bronchial fistula (HBBF) are rare complications of hydatid cysts of the liver with high perioperative mortality. Case presentation and clinical discussion: The authors here report the case of a patient with a right massive pleural effusion with evidence of HBBF in imaging studies, who underwent surgical resection of a hydatid cyst of the liver 8 years ago. The patient was managed with intercostal chest tube drainage for biliothorax and endoscopic sphincterotomy with biliary stent placement for the re-establishment of internal biliary drainage, which ultimately allowed the fistulous tract to heal without any major surgical intervention. Conclusion: This article focuses on the successful management of the HBBF at our institution. Our findings emphasize the significance of early diagnosis and the criticality of implementing aggressive and early interventions to minimize complications and fatalities. By examining this specific case and reviewing existing literature, the authors have determined that endoscopic treatment appears to be a viable, secure, and efficacious option for addressing postoperative HBBF.

Esophageal variceal bleeding: portal hypertension and portal vein thrombosis secondary to protein S deficiency - a case report.

Introduction: Proteins C and S play a key role in the inhibition of the coagulation cascade. Deficiencies of proteins C and S deficiency are rare conditions that lead to abnormal activation of the coagulation cascade, resulting in a prothrombotic state and an increased risk of venous thromboembolism. These deficiencies also pose a risk factor for the development of portal vein thrombosis (PVT). PVT secondary to these deficiencies in the acute phase is usually asymptomatic, but the disease in chronic cases may present with features suggestive of portal hypertension, usually hepatosplenomegaly, variceal bleeding. However, cavernous transformation of the portal vein due to proteins C and S is usually rare. Introduction and Importance: Proteins C and S are rare thrombophilic disorders that may present even with PVT, resulting in esophageal bleeding as an uncommon presentation. Hence, protein S and protein C deficiency should also be considered a cause of noncirrhotic portal hypertension with esophageal bleeding. Case Presentation: The authors hereby present you with the case of a 22-year-old female who presented with complaints of abdominal pain and black-colored stool in the emergency department. Clinical Discussion: Relevant investigations were sent, and she was treated in line with esophageal variceal bleeding with the cavernous transformation of a thrombosed portal vein secondary to noncirrhotic portal hypertension due to protein C and S deficiency. Esophageal varices were managed with rubber band ligation. An oral anticoagulant was started for the thrombophilic disorder. The patient was also advised for splenectomy for splenomegaly and ongoing anemia and thrombocytopenia. Conclusion: The main aim of the article is to highlight a rare case of protein S deficiency that has led to upper GI bleeding due to esophageal varices secondary to portal hypertension secondary to PVT. Esophageal variceal bleeding secondary to PVT is an uncommon presentation of protein S deficiency. PVT without liver cirrhosis is also uncommon. Protein S and C deficiency is a rare clotting disorder that may cause clots in vessels and ultimately dislodgement of clots that can result in life-threatening complications. Hence, timely diagnosis, treatment, and prophylaxis can prevent life-threatening complications.

Nonhealing oesophageal ulcer: a case report.

Esophageal tuberculosis is a rare presentation of a common infectious disease. It may occur as a primary infection of the esophagus or as a secondary spread mostly from caseating mediastinal lymph nodes. The clinical diagnosis of the condition is presumed to be complex, owing to nonspecific biopsy findings, failure of isolation of bacilli, and a lack of predisposing conditions in patients. This study aims to present a rare condition of esophageal tuberculosis secondary to mediastinal lymphadenitis and highlights a unique modality of diagnosis of the condition, especially in a resource strained setting. Case presentation: This case report presents the case of a 50-year-old male with dysphagia and a burning sensation at the epigastrium. Endoscopy and histopathological examination showed ulceration at the esophagus and granulomatous inflammation, respectively. Computed tomography showed enlargement of the prevascular and paratracheal group of lymph nodes. However, the acid-fast bacilli stain at the ulcer site was negative. The diagnosis could be confirmed only after 2 months of the antitubercular treatment trial, which significantly potentiated ulcer healing. Clinical discussion: Esophageal tuberculosis may result from a secondary infection caused by systemic dissemination following a pulmonary disease or as a primary infection. In this case, it likely resulted from lymphatic dissemination via prevascular and paratracheal lymph nodes manifested mainly as dysphagia. Conclusion: Tuberculosis should be considered as one of the differential diagnoses in areas of limited resources. Clinicians may have to rely on clinical judgement and/or the patient's response to standard antitubercular treatment to make a definitive diagnosis.

Anticoagulation failure in pulmonary thromboembolism in COVID-19 pneumonia despite prolonged anticoagulation: A case series.

Introduction: Moderate to severely ill patients diagnosed with Coronavirus disease 2019 (COVID-19) pneumonia develop a series of complications and less frequently, we might witness cases of Pulmonary Thromboembolism (PE)-refractory to the standard treatment with Low Molecular Weight Heparin (LMWH). The aim of this case series is to report the presentation and management of pulmonary thromboembolism secondary to COVID-19 pneumonia. Method: We report a case series of seven cases aged 40-70 who were presented in Dhulikhel Hospital with COVID-19 symptoms in different stages. The case details were extracted from their medical reports of the hospital. The written informed ethical consents were obtained from all the cases and their voluntary participation was assured. Outcome: The cases in the case series admitted with COVID-19 pneumonia, after diagnostic investigation (Chest x-ray, HRCT, CTPA) were suggestive of COVID-19 Pneumonia with ARDS and pulmonary thromboembolism. The cases received rivaroxaban, a newer anticoagulant-15 mg twice daily for 21 days and after discharge, they were asked to continue once daily doses for 9 weeks. Significant improvement was witnessed, with the presence of additional intervention including rehabilitative chest exercises. Conclusion: Pulmonary thromboembolism secondary to COVID-19 pneumonia is a life-threatening condition. Rivaroxaban is seen to be very effective in the management of this condition when an anticoagulation failure occurs even after the therapeutic dose of low molecular weight heparin. Future studies may require more scientific investigations to prevent complications even in the early stages of COVID-19.

Autoimmune gastritis in a male adolescent with cerebellar involvement: A case report.

Introduction: Autoimmune gastritis is an immune mediated disorder characterized as anti-intrinsic factor and anti-parietal cell autoantibodies directed against intrinsic factor and parietal cells of the stomach respectively, leading to vitamin B12 deficiency. When the disease remains undiagnosed and untreated, it may lead to neurological complications and even fatal anemia. Case study: We exemplify a non-vegetarian male adolescent case with the neurological symptoms such as bilateral leg weakness, unsteady gait, slurred speech, vertigo, slowed movement, lethargy, and impaired joint sensation. None of his family members had such illness. His hemoglobin was normal with serum vitamin B12 level 105 pg/mL and anti-intrinsic factor antibody titer positive. A presumed diagnosis of cobalamin deficiency with involvement of the cerebellum, dorsal column and peripheral nerves was made. His symptoms recovered gradually and later completely (after 6 months) after the intramuscular vitamin B12 therapy. Clinical discussion: The indexed rare adolescent case had auto immune gastritis showing neurological manifestation with more pronounced cerebellar features and vitamin B12 deficiency under the non-vegetarian diet consumption. Previous studies had reflected auto immune among adolescents but contrasted some of the clinical features. Conclusion: For the prompt and precise diagnosis of the autoimmune gastritis and to prevent further complications, some of the rare conditions such as deficiency with a non-vegetarian diet, neurological manifestation including cerebellar involvement without anemia should also be considered along with other relevant symptoms. The heightened awareness for timely surveillance and treatment will contribute in reduction of such unusual cases.

Rhegmatogenous Retinal Detachment with Spontaneous Dialysis of the Ora Serrata in Neurofibromatosis Type 1: A Case Report.

Neurofibromatosis type 1 is a genetic disorder that follows an autosomal dominant pattern of inheritance. Ocular involvement is not uncommon, but spontaneous dialysis of the retina in the absence of a history of trauma is a rare clinical entity. Rare cases of retinal involvement such as retinal detachment or dialysis of ora serrata could be linked with the abnormal cell-matrix formation in neurofibromatosis type 1. Here, we present a case of a 36-year-old man having Neurofibromatosis Type 1 with spontaneous dialysis of ora serrata without prior history of ocular trauma. A routine fundoscopic examination should be done in addition to the examination of the anterior chamber in patients with neurofibromatosis type 1 despite the absence of ocular complaints. Keywords: case reports; neurfibromatosis type 1; ora serrata; retinal; retinal detachment.

Cronkhite-Canada Syndrome: A Case Report.

Cronkhite-Canada Syndrome is a rare disease characterised by diffuse gastrointestinal polyposis, abdominal pain, diarrhoea, cutaneous and mucosal hyperpigmentation, alopecia, and onychodystrophy. Here we report a case of a 40-year-old female with Cronkhite-Canada Syndrome, who presented with the complaints of diffuse abdominal pain, blood mixed stools, and diarrhoea associated with tenesmus. She had nausea and reduced appetite and lost 10 kgs in 3 months. She had hair fall (alopecia), atrophic changes of nails (onychodystrophy), and hyperpigmentation of the skin in fingers, tongues, and lips. Histopathological biopsy of the gastric and colonic biopsy revealed polypoid edematous mucosa and the colonic biopsies showed scattered dilated glands with inflammatory exudate and mucin. She got Entamoeba histolytica and COVID-19. She received respective antibiotics and protein diets that helped relieve the symptoms. After 4 weeks of steroids, her symptoms improved drastically. Corticosteroids, treating co-infection along with nutritional counselling can be helpful to relieve the symptoms. Keywords: alopecia; case reports; cronkhite-canada syndrome; hyperpigmentation.
