V-011 * gastrointestinal stromal tumour of the oesophagus in the aortopulmonary window operated from the right side
Conclusions GISTs are rare malignant tumours of the oesophagus. Enucleation of the tumour without resection of the oesophagus is justified in tumours up to 4 cm and low malignant potential. Even left-sided tumours can be operated from the right side by VATS. Disclosure All authors have declared no conflicts of interest.

Giant gastrointestinal stromal tumour of rare sarcomatoid epithelioid subtype: Case study and literature review.
We report this case and review the literature with a special focus on pathomorphological evaluation, biological aggressiveness and prognostic factors. To our knowledge this is the first report of giant GIST of very uncommon sarcomatoid epithelioid subtype. It is concluded that clinicians should pay attention to the fact that initial diagnosis may be delayed due to mildly asymptomatic and non-specific clinical presentation. Asymptomatic tumours diagnosed at a late stage, which is often the case, can be large on presentation. Prognosis for patients diagnosed with GIST depend on tumour size, mitotic rate, histopathologic subt...

Obscure gastrointestinal bleeding due to gastrointestinal stromal tumors.
CONCLUSION: GIST can have multiple clinical pictures and unusual symptoms, such as obscure gastrointestinal bleeding. The use of computed tomography and angiography has shown to be an important tool in the diagnosis with patients with small intestine GISTs. PMID: 27855991 [PubMed - as supplied by publisher]

Laparoscopic resection of a gastrointestinal stromal tumour in a Meckel & #39;s diverticulum
Sala Abdalla, Tayo OkeJournal of Minimal Access Surgery 2019 15(4):339-341A Meckel's diverticulum (MD) is a congenital abnormality of the gastrointestinal tract which is estimated to be present in 2% of the population. Gastrointestinal stromal tumours (GISTs) are rare, soft-tissue tumours which represent 0.1%–3% of all gastrointestinal tumours. The association of an MD and a GIST is extremely unusual since fewer than 3% of MD harbour primary neoplasms and most of these neoplasms are carcinoid tumours. While MDs may remain asymptomatic throughout life, a sm...

Ten‐year review of gastrointestinal stromal tumours at a tertiary referral hospital in New Zealand
ConclusionSurgery aiming at an R0 resection remains the mainstay of treatment. We propose the most effective way to grow the knowledge base in New Zealand is the establishment of a national register, thereby allowing better clinical decision‐making by interpretation of a larger data set.

Unusual presentation of a giant jejunal gastrointestinal stromal tumor.
CONCLUSION: The information in the literature is examined. Spontaneous rupture of the tumor with concomitant hemoperitoneum is an important prognostic factor in these patients. The hemoperitoneum contributes to a worse prognosis because of its ability to produce peritoneal seeding KEY WORDS: Gist. PMID: 32913145 [PubMed - in process]

Extraluminal gastrointestinal stromal tumour (GIST) located at the splenic flexure of the colon
We present a case of an elderly male patient with the extraluminal location of a large gastrointestinal stromal tumour at the splenic flexure of the colon which was accidentally discovered at a routine CT examination of the abdomen after a fall on the ground. The literature on this rare modality is briefly reviewed.

Initial Presentation of a Giant Gastrointestinal Stromal Tumour of the Stomach With Recurrent Spontaneous Intra-peritoneal Haemorrhage
Conclusion GISTs are uncommon and rarely present with spontaneous intra-peritoneal haemorrhage, which may be life threatening. In our understanding, this is the first reported case of the reviewed literature presenting with a chronic hemoperitoneum, due to recurrent brisk episodes of tumour haemorrhage. Tumour rupture and large tumour size are two poor independent prognostic tumour factors for recurrence. Despite this, the patient remains free of disease after surgery and instituted adjuvant Imatinib mesylate.

Primary mesenteric gastrointestinal stromal tumour with concomitant mesenteric tuberculosis: Careful histopathology is essential
Trop Doct. 2022 Feb 14:494755221076947. doi: 10.1177/00494755221076947. Online ahead of print.ABSTRACTGastro-inestinal stromal tumours (GISTs) comprise 1-2% of all gastrointestinal (GI) tumours. The mesentery, retroperitoneum and omentum are common sites of extra-gastrointestinal stromal tumours (E-GISTs). Isolated involvement of the mesentery by tuberculosis (TB) without any evidence of pulmonary disease is quite unusual. Here we report a case of an E-GIST arising from the small bowel mesentery in a 60-year old female where an incidental concurrent mesenteric tuberculosis was diagnosed following surgical resection.PMID:35...

Primary hepatic gastrointestinal stromal tumor: A case series
Asian J Surg. 2021 Oct 9:S1015-9584(21)00576-5. doi: 10.1016/j.asjsur.2021.09.003. Online ahead of print.ABSTRACTThe liver is the most common metastasis site of gastrointestinal stromal tumours (GISTs). However, primary hepatic gastrointestinal stromal tumours (PHGISTs) are also reported, which is no more than 40 cases to date. PHGISTs are mostly misdiagnosed preoperatively due to the lack of specific symptoms and imaging features. It majorly attributes to vague characteristics on CT or MRI, which PHGISTs almost meet the imaging diagnosis criteria of hepatocellular carcinoma (HCC) or hepatapostema. Here we reported an educ...

The Management of Unresectable, Advanced Gastrointestinal Stromal Tumours
AbstractGastrointestinal stromal tumours (GISTs) are the most common gastrointestinal tract mesenchymal tumours. Tyrosine kinase inhibitors (TKIs) have transformed the management of advanced GIST. Imatinib was the first TKI to gain approval as management for patients with advanced GIST, establishing a new standard of care. Since then, as a result of several trials including the GRID and INVICTUS studies, we now have five lines of approved targeted therapy, including imatinib, sunitinib, regorafenib, ripretinib and avapritinib for the treatment of unresectable, advanced GISTs. In this review, the Australasian Gastrointestin...
