BackgroundIntussusception in adult patient is rare. Gastroduodenal intussusception due to the gastrointestinal stromal tumors is infrequently described in the literature. Authors present a case of gastroduodenal intussusception due to the low-risk gastrointestinal stromal tumor of the lesser curvature of the gastric body with literature review.Case presentationSixty-two-year-old male was admitted to our hospital with symptoms of acute gastric outlet obstruction. Imaging studies confirmed a lesion of the gastric wall producing gastroduodenal intussusception with pylorus obstruction. Upon laparotomy a tumor mass of the lesser curvature of the gastric body that invaginated through the pylorus into the duodenum was found. Desinvagination and resection of the tumor with the adequate resection margins were performed. Histology reveled a low-risk gastrointestinal stromal tumor. Due to favorable outcome only observation was suggested by the multidisciplinary team.ConclusionsGastroduodenal intussusception due to the gastrointestinal stromal tumor of the gastric wall is a rare event. Surgical resection is the treatment of choice. In selected cases laparosopic resection of the tumor can be performed.
BackgroundSmall bowel intussusception in adults is rarely encountered. In most cases small bowel intussusception is caused by benign neoplastic lesions, but metastasis of cutaneous malignant melanoma causing small bowel intussusception is rare. We present such a case of jejuno-jejunal intussusception with an intraluminal metastatic lesion acting as a lead point.Case presentationWe present a case of a 71-year-old Caucasian man who presented with small bowel obstruction. His medical history revealed that he had had a cutaneous malignant melanoma excised 7 years earlier and underwent total laryngectomy due to a metastasis 6 years later. The disease was classified as stage IV and he was receiving immunotherapy. An emergency abdominal computed tomography scan demonstrated small bowel obstruction, most probably caused by an intraluminal lesion. An emergency laparotomy revealed an intraluminal metastatic lesion causing jejuno-jejunal intussusception. Metastasectomy of the lesion was performed and 13 days later he was discharged.ConclusionsJejuno-jejunal intussusception with a malignant melanoma metastasis acting as a lead point is very rare. With the gastrointestinal tract being a common location of distal metastases, a medical history of malignant melanoma treatment in cases of small bowel obstruction should raise a suspicion of possible metastatic disease. A computed tomography scan is the diagnostic modality of choice and surgery still remains the standard of care.
Background
A better appreciation of the course and factors that influence incidental gallbladder cancer (iGBC) is needed to develop treatment strategies aimed to improve outcomes. The purpose of the study was to determine the influence of residual disease in the liver and lymph nodes on overall survival in re-resected patients with iGBC.
Patients and methods
Patients undergoing radical re-resection for iGBC from January 2012 to December 2018 were retrospectively identified. Patients with a 5-year follow-up and submitted to complete resection with stage I, II and III disease were analysed. The influence of residual disease (RD) in liver and lymph nodes on survival was assessed using the Kaplan-Meier curves. In addition, the rest of the group was assessed based on type of primary/secondary procedure, number of harvested lymph nodes and RD in liver and/or lymph nodes.
Results
In this retrospective study 48 out of 58 (83%) patients underwent re-resection. Among the group with a 5-year follow-up (re-operation between 2012–2014), 22 patients out of 28 (79%) were re-resected. Survival analysis showed that patients with no RD in the liver and lymph nodes had statistically significant better 5-year survival than those with RD. Comparing 5-year survival rate in patients with RD in the liver or lymph nodes against no RD group, patients with RD in the liver had statistically significantly worse 5-year survival, while lymph node metastases did not show any statistically significant different in 5-year survival. Besides, a statistically significant better prognosis was found in stage II disease compared to stage III, as expected.
Conclusions
The most important predictors of a 5-year survival in our study were RD in liver and stage of the disease. Lymph node metastases did not have any impact on the overall 5-year survival rate.
Mixed acinar-ductal carcinoma is rare among pancreatic cancers, as is duodenal involvement in follicular lymphoma (FL). Although usually a systemic disease, primary FL of the duodenum occurs, with superficial involvement of the intestinal wall and low risk of progression. We report on a unique case of mixed ductal-acinar carcinoma of the pancreatic head accompanied by low-grade duodenal FL and autoimmune pancreatitis-like changes in adjacent pancreatic parenchyma. To our knowledge this is the first report of concomitant pancreatic mixed acinar-ductal carcinoma and duodenal FL. Clinico-pathological features of this unusual case, possible relationship between the entities and differential diagnosis are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
