IntroductionTuberculosis is a major health problem worldwide. Sudan has high burden of tuberculosis (TB) with a prevalence of 209 cases per 100,000 of the population and it is commonly presented with pulmonary disease but involvement of the gastrointestinal tract is not uncommon. Abdominal tuberculosis comprises about 1–3 % of all cases of tuberculosis and about 12% of extrapulmonary tuberculosis. It involves the ileocecal region, but involvement of stomach and duodenum are rare sites. Here we present an unusual case of gastric outlet obstruction due to gastric tuberculosis.Case presentationA 54-year-old Sudanese man presented with a non-bile stain persistent projectile vomiting, and epigastric pain for two years associated with marked loss of weight. There is no fever or cough. He was on antacid, physical examination showed BMI 18 and stable vital signs. He was not pale or jaundiced, there was no cervical lymphadenopathy and chest was clear. Abdominal examination was normal apart of positive succussion splash. The results of haematological tests were normal, ESR was 30 mm/hr, hepatitis B, C and HIV were negative. Upper gastrointestinal endoscopy showed that the stomach was full of fluid and food particles and ulcerated mass in the pylorus extended to the proximal part of the duodenum with severe narrowing of the pylorus. The lesion biopsied and the result revealed active inflammatory cells, cryptitis and multiple lymphoid follicles, no malignancy seen. Sonographic test showed hypodense pyloric mass, enlarged para-aortic and mesenteric lymph nodes and mild pelvic ascites. A computed tomography scan of the abdomen and pelvis showed antral hypodense lesions multiple mesenteric lymphadenopathies peritoneal thickening and ascites. Chest X-ray was normal. Intra-operative findings were dilated stomach and pylorus mass with multiple mesenteric lymph nodes, peritoneal and omental seedlings all over with small nodules on the surface of the liver, gastro-jejunostomy was done. Histopathology confirmed the diagnosis of abdominal tuberculosis. Postoperative event was uneventful. Patient received anti-tuberculous.ConclusionsHere we presented an unusual case of gastric outlet obstruction due to primary gastric tuberculosis, patient underwent surgery to relief his symptoms and received anti-tuberculous.

IntroductionThe gastrointestinal stromal tumour is one of the common mesenchymal tumours of the gastrointestinal tract. It originates from the interstitial cells of Cajal. Gastrointestinal stromal tumours that present outside the gastrointestinal tract are called extragastrointestinal stromal tumours; they share the same morphological and immunohistochemical characteristics. Here we describe an unusual case of extragastrointestinal stromal tumour that presented with gooseberry-like multiple nodules involving the whole abdominal cavity.Case presentationA 65-year-old Sudanese man presented with vague abdominal pain and progressive abdominal distension for 6 months. The pain was associated with mild loss of weight despite good appetite. A physical examination revealed distended abdomen with multiple firm nodules involving his whole abdomen. The results of haematological tests were within normal range. Ultrasound of his abdomen showed multiple nodules of varying sizes in the peritoneal cavity. A computed tomography scan of his abdomen showed numerous nodules of different sizes (1 to 3cm in diameter) filling the whole peritoneal cavity with intense peripheral enhancement. Ultrasound-guided biopsy was not informative. Upper and lower gastrointestinal endoscopies were normal. Exploration of his abdomen revealed multiple firm gooseberry-like nodules of different sizes involving the greater omentum, peritoneal cavity and the mesentery. The liver, spleen and pancreas were normal. The result of the histopathology was conclusive for gastrointestinal stromal tumour.ConclusionsHere we present a rare case of extragastrointestinal stromal tumour in a patient who presented with vague abdominal pain and progressive abdominal distension. A laparotomy showed gooseberry-like multiple nodules of different sizes involving his whole abdominal cavity. He underwent debulking surgery and received imatinib.

Background: Periampullary tumor involves ampullary, pancreatic, biliary and duodenal mucosa, and pancreaticoduodenectomy considered the curative option. Hence, imaging evaluation to describe the lesion is important. Furthermore, certain specific features could help in pre-operative prediction of resectability for periampullary cancers. The aim of this study is to find out any specific perioperative predictor of resectability on periampullary cancers. Patients and Methods: This is an observational cross-sectional hospital-based study done in tertiary hospital, a total of 79 patients were included in the study. Variables such as age, gender, symptoms (back pain, jaundice, etc.), investigations (bilirubin, alkaline phosphatase, etc.), and imaging (Triphasic computed tomography [CT], magnetic resonance cholangiopancreatography, endoscopic ultrasonography, etc.) were studied and the data collected and analyzed using SPSS 20. Results: Male was slightly predominant and male to female ratio was 1:0.9. The mean age was 50 years (SD ±6.54). Triphasic CT abdomen pancreatic protocol was the most effective modality of investigation. High bilirubin (>10 mg/dl) and back pain were statistically significant among patients with unresectable tumor. Conclusions: Back pain and high bilirubin could be helpful in pre-operative prediction of operability of periampullary cancers.
