A Case Report of a Bleeding Duodenal Gastro-Intestinal Stromal Tumor and its Emergent Management

A gastrointestinal stromal tumor (GIST) arising in the duodenum is a rare subtype of mesenchymal tumor. GISTs have a reported incidence of 11.9–19.6 per million population and duodenal GISTs make up just 5% of these tumors. Common presentation of duodenal GISTs is through an upper gastrointestinal bleed, of which, they are responsible for less than 1% of all gastrointestinal bleeding. In an elective setting, surgical management remains the mainstay of treatment. In this Case Report, the emergent management of a localized duodenal resection was performed by an acute care surgeon, in an unstable patient. The risk factors for malignancy include tumor size and a high mitotic cell index. Tumor recurrence is determined by tumor size, tumor rupture, high mitotic cell index, a non-gastric location and gastrointestinal bleeding.

A Giant Gastrointestinal Stromal Tumor of Duodenal Origin with Spontaneous Rupture Bleeding: A Case Report

BackgroundThe duodenum is a rare site of gastrointestinal stromal tumors (GISTs). The unique anatomical characteristics and rich blood supply of the duodenum make it difficult to treat duodenal GISTs in patients with bleeding.Case presentationHere we report a case of a 76-year-old female was hospitalized with a large GIST that originated in the duodenum. Imaging assessment suggested that the tumor could not be radically resected. However, the tumor was rupturing and bleeding, and therefore pancreaticoduodenectomy had to be performed. After receiving imatinib postoperatively, the patient has recovered during the 1 year after the operation.ConclusionThe results of this case suggest that pancreaticoduodenectomy may be a better choice for duodenal GISTs with rupture and bleeding.

A Case Presentation of Gastrointestinal Stromal Tumor of Duodenum

A gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract. It is caused by the mutation in KIT and PDGFRα genes. It constitutes <1% of all gastrointestinal tumors. Duodenal GISTs constitute 4.5% of all GISTs. We report a 61-year-old lady, presented with generalized abdominal pain, vomiting, abdominal distension, and nausea for the last 3 years. Physical exam-ination showed a pallor and on abdominal examination, a large palpable mass was extending from the pelvis to the right upper quadrant of the abdomen. The CT scan showed a large heterogeneously echogenic mass in the abdomen and pelvis with no lymphadenopathy and distant metastasis in this region. Laparotomy showed a large globular mass extending from the pelvis to the right upper quadrant of the abdomen adherent to the wall of a third part of the duodenum. Complete surgical resection of tumor done with an intact capsule. Microscopic examination showed neoplastic spindle cells with tumor necrosis. An immunohistochemical study confirmed GIST.

Large Duodenal Gastrointestinal Stromal Tumour Invading the Pancreas- A Masquerader for Pancreatic Head Mass

Gastrointestinal Stromal Tumours (GISTs) are the most common mesenchymal tumours of the gastrointestinal tract commonly arising from stomach and small intestine. Duodenal GISTs are rare. Though uncommon, GISTs can arise from the omentum, mesentery, gallbladder as well as retroperitoneum and are defined as Extra GISTs (EGIST). Authors have reported a case of large GIST arising from the second part of the duodenum and mimicking the large pancreatic head mass in a 34-year-old female patient presented with abdominal pain and vomitings. The Contrast Enhanced Computed Tomography (CECT) revealed a large enhancing mass in the pancreatico-duodenal groove not separated from pancreatic head. Whipple’s surgery was performed. Histopathology and Immuno-histochemistry report revealed the duodenal GIST with pancreatic infiltration with high risk for metastases according to mitotic index and size. Sometimes large duodenal GISTs can make the diagnosis difficult radiologically due to invasion of pancreatic head and mimic as primary pancreatic head tumour.

Clinicopathological Characteristics, Surgical Treatments, and Survival Outcomes of Patients with Duodenal Gastrointestinal Stromal Tumor

Background: Duodenal gastrointestinal stromal tumors (GISTs) are rare and their clinicopathological features have not been completely described. In this retrospective study, we examined the characteristics and long-term outcomes of patients who underwent surgical treatment for duodenal GISTs. Methods: We examined patients surgically treated for duodenal GISTs from 1999 to 2016 at the China National Cancer Center. We analyzed patient characteristics, treatments, histological examinations, and survival outcomes. Results: The 52 surgeries performed included 14 pancreaticoduodenectomies (26.9%), 37 limited resections (71.2%), and one palliative bypass procedure (1.9%). No surgery-related death occurred. The complication rate in patients who underwent pancreaticoduodenectomy was slightly higher than that in patients who underwent limited resection. The 5-year overall survival and progression-free survival rates for patients with duodenal adenocarcinoma were 89.1 and 72.9%, respectively. The overall survival and progression-free survival rates were not significantly related to surgical methods. Large tumor size and high mitotic rate were associated with poor overall survival outcomes. However, no independent factor was associated with prognosis, which may be due to the small sample size. Conclusion: The prognosis of duodenal gastrointestinal stromal tumors was good. Limited resection seems to be oncologically feasible, with outcomes being less worse than those of pancreaticoduodenectomy.

A Pancreatic Head Tumor Arising as a Duodenal GIST: A Case Report and Review of the Literature

Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors of the gastrointestinal tract that originate from theintestinal cells of Cajal(ICC) (Fletcher et al., 2002). Only a few cases have been described with extragastrointestinal stromal tumors (Kim et al., 2012; Soufi et al., 2013; Meng et al., 2011). They are often diagnosed as a pancreatic head tumor as they are very difficult to relate to the duodenum with CT, MRI, or ultrasound. We present a case of a sixty-four-year-old woman who presented with abdominal pain and cardialgia for a follow-up examination after breast cancer surgery. On laparotomy there was a 3 × 5 cm hypervascular mass arising from the pancreatic head with macroscopically no attachment to the duodenum. The patient underwent pancreatoduodenectomy (PD) modified after Traverso-Longmire, histopathology proved a duodenal GIST. This case proves that duodenal GISTs can grow invasively into the pancreas and appear as solid pancreas head tumor; therefore, these tumors should be included into differential diagnosis.

Duodenal Wedge Resection for Large Gastrointestinal Stromal Tumour Presenting with Life-Threatening Haemorrhage

Background. Duodenal gastrointestinal stromal tumours (GISTs) are an uncommon malignancy of the gastrointestinal (GI) tract. We present a case of life-threatening haemorrhage caused by a large ulcerating duodenal GIST arising from the third part of the duodenum managed by a limited duodenal wedge resection.Case Presentation. A 61-year-old patient presented with acute life-threatening gastrointestinal bleeding. After oesophagogastroduodenoscopy failed to demonstrate the source of bleeding, a 5 cm ulcerating exophytic mass originating from the third part of the duodenum was identified at laparotomy. A successful limited wedge resection of the tumour mass was performed. Histopathology subsequently confirmed a duodenal GIST. The patient remained well at 12-month followup with no evidence of local recurrence or metastatic spread.Conclusion. Duodenal GISTs can present with life-threatening upper GI haemorrhage. In the context of acute haemorrhage, even relatively large duodenal GISTs can be treated by limited wedge resection. This is a preferable alternative to duodenopancreatectomy with lower morbidity and mortality but comparable oncological outcome.
