RESUMEN

BACKGROUND: Mycobacterium tuberculosis (TB) is the causative agent of TB, a chronic granulomatous illness. This disease is prevalent in low-income countries, posing a significant global health challenge. Gastrointestinal TB is one of the three forms. The disease can mimic other intra-abdominal conditions, leading to delayed diagnosis owing to the absence of specific symptoms. While gastric outlet obstruction (GOO) remains a frequent complication, its incidence has declined with the advent of proton pump inhibitors and Helicobacter pylori eradication therapy. Gastroduodenal TB can cause upper gastrointestinal hemorrhage, obstruction, and malignancy-like tumors. CASE SUMMARY: A 23-year-old male presented with recurrent epigastric pain, distension, nausea, vomiting, and weight loss, prompting a referral to a gastroenterologist clinic. Endoscopic examination revealed distorted gastric mucosa and signs of chronic inflammation. However, treatment was interrupted, possibly owing to vomiting or comorbidities such as human immunodeficiency virus infection or diabetes. Subsequent surgical intervention revealed a dilated stomach and diffuse thickening of the duodenal wall. Resection revealed gastric wall effacement with TB. CONCLUSION: Primary gastric TB is rare, frequently leading to GOO. Given its rarity, suspicions should be promptly raised when encountering relevant symptoms, often requiring surgical intervention for diagnosis and treatment.

RESUMEN

Abdominal tuberculosis (TB) can affect any part of the gastrointestinal tract, solid organs, peritoneum, or lymph nodes. The diagnosis of abdominal TB is usually delayed due to a lack of specific clinical signs and symptoms and the mimicking of other intra-abdominal diseases. We present a case of gastroduodenal tuberculosis with peripancreatic lymph node involvement presented as a gastric outlet obstruction that was treated conservatively with anti-tuberculosis medications.

RESUMEN

AIM: To compare multidetector computed tomography (MDCT) and dual-energy computed tomography (DECT) imaging findings in gastrointestinal (GI) tuberculosis. OBJECTIVE: To study imaging findings of MDCT and DECT in GI tuberculosis. METHODOLOGY: All the patients falling in the sampling frame and fulfilling the eligibility criteria were clinically examined and demographic details, presenting complaints, medical history, history of anti-tubercular treatment (ATT) intake, personal habits, and family history of tuberculosis were noted. All the patients underwent sputum acid-fast bacilli (AFB) assessment. Outcomes of investigations like bronchoscopy and fine-needle aspiration cytology (FNAC)/biopsy were also noted wherever available. Ascitic fluid AFB and culture assessments were also performed wherever feasible. All CT scans were performed on a 384-slice dual-energy CT scanner (Somaton Force, Siemens Healthcare) and all the images were post-processed on a workstation using syngo.via software that allows the analysis of images using three material decompositions. Features like peritonitis, lymph node involvement, GI wall thickening, and solid organ involvement were focused on. Subjective assessment of images of both MDCT and DECT were assessed by two experienced radiologists to prepare the CT diagnosis. The mutual agreement of the two observers was considered final. CONCLUSIONS: The findings of the study showed that both MDCT, as well as DECT, were useful in the diagnosis of GI tuberculosis. On the basis of these findings, DECT could be considered to have an edge over MDCT in the diagnosis of GI tuberculosis. Keeping in view the small sample size and high prevalence, further studies on a larger sample size with relaxed sampling criteria are recommended to validate the findings of the present study.

RESUMEN

BACKGROUND: Tuberculosis (TB) is a major health problem worldwide. Even in highly prevalent countries, primary gastroduodenal tuberculosis is a rare manifestation of extrapulmonary tuberculosis. In recent years, as the incidence of tuberculosis has increased year by year, the occur of gastroduodenal tuberculosis has also increased. Endoscopy is an important tool for diagnosing gastroduodenal tuberculosis. The performance of gastroduodenal tuberculosis under endoscopy is often non-specific, which may imitate other benign or malignant gastroduodenal diseases. Diagnosis of gastroduodenal tuberculosis relies on a combination of endoscopy and guided biopsy. CASE PRESENTATION: Here, we report a rare and interesting case of gastroduodenal tuberculosis with acute pancreatitis. The case initially mimicked gastroduodenal ulcers in morphology and appeared in a middle-aged person with normal immunity but with prolonged fever and abdominal pain. The disease was diagnosed through endoscopy and guided biopsy, and it responded well to antituberculosis drugs. CONCLUSIONS: Clinicians must remember that even in the absence of immunodeficiency, as in this case, tuberculosis can affect any part of the gastrointestinal tract.

RESUMEN

Gastrointestinal tuberculosis manifesting as isolated duodenal involvement is uncommon. We present a case of 52 years old man with post-prandial abdominal pain, early satiety and weight loss. Upper endoscopy showed circumferential duodenal stricture adjacent to the ampulla with nodularity, erythema, and ulcerations of the overlying mucosa causing gastric outlet obstruction. Biopsy of duodenal stricture revealed chronic duodenitis and the patient was treated with acid suppression therapy. Endoscopic balloon dilation was also performed with no response. Abdominal computer tomography scan showed multiple enlarged abdominal lymph nodes and subsequent duodenal tissue culture was positive for Mycobacterium tuberculosis. His symptoms and duodenal stricture resolved completely after treatment with anti-tuberculous regimen.
