Horseshoe kidney is the most common renal fusion anomaly and is associated with various complications, ranging from infections to neoplasms. While renal cell carcinoma (RCC) is the most frequent renal neoplasm in adults, its occurrence in a horseshoe kidney is rare, and bilateral involvement is rarer. Furthermore, RCC metastasizing to organs is known and rare sites of metastasis are also documented. The report presents a unique case of bilateral RCC in a horseshoe kidney with synchronous metastasis to the gallbladder, pancreas, and duodenum. This presentation, involving metastasis to these specific organs, is exceedingly uncommon, making it a rarest of rare possibilities. The current case report underscores the importance of vigilant monitoring and comprehensive evaluation in patients with horseshoe kidneys, as they may be predisposed to unusual complications like RCC and rare site metastasis.

We experienced a case of bilateral corneal thinning during the oral taking of S-1, a combination anti-cancer drug of tegafur, gimeracil, and oteracil-potassium. A 69-year-old man was prescribed oral S-1 for the treatment of duodenal papilla adenocarcinoma and intraductal papillary mucinous neoplasm. However, he developed a decrease in visual acuity in both eyes after three cycles of S-1 oral taking, and ophthalmic examination revealed corneal thinning exceeding 100 µm and an increase in high-order irregularity of cornea in both eyes. After one month after discontinuation of S-1, his visual acuity and corneal thickness returned to its previous levels. Besides corneal ulcers and perforations, corneal thinning can be recognized as a potential corneal side effect necessitating monitoring during S-1 treatment.

A 67-year-old man presented to our hospital with vomiting. Esophagogastroduodenoscopy revealed duodenal stenosis and atypical epithelium. A tumor in the pancreatic head, about 30mm in size, involving the superior mesenteric artery and a superior mesenteric vein was identified using abdominal contrast computed tomography (CT). Locally advanced pancreatic cancer was diagnosed in the patient through an endoscopic biopsy. Due to the duodenal stenosis complication, duodenal stent placement was conducted. After stent placement, oral intake was resumed, and improvement of the systemic condition led to chemotherapy (modified FOLFIRINOX). After chemotherapy, CT revealed decreased carcinoma progression and vascular invasion. Conversion surgery was improved, and R0 resection was achieved. Our study showed that duodenal stent placement could enhance prognosis;as a result, it was regarded as a good choice for multidisciplinary therapy.

Our aim was to investigate the clinical outcome of patients with well-differentiated gastric, duodenal, and rectal neuroendocrine tumors after treatment with incomplete endoscopic resection due to the finding of microscopic positive resection margins (R1). This is a retrospective analysis of consecutive patients with type 1 gastric, non-ampullary non-functioning duodenal, or rectal neuroendocrine neoplasms with positive R1 margins after endoscopic resection. The rate of tumor recurrence and progression-free survival were considered to be the study's main endpoints. Statistical analysis was performed using MedCalc v.17 software and a -value of <0.05 was considered significant. A Cox proportional-hazard regression was performed to identify risk factors for disease recurrence/progression. After evaluating 110 patients, a total of 58 patients were included in the final analysis (15 gastric NENs, 12 duodenal NENs, and 31 rectal NENs). After evidence of endoscopic R1 resection had been gathered, 26 patients (44.8%) underwent an endoscopic/surgical extension of the previous resection. Tumor progression (all local recurrences) occurred in five out of fifty-eight patients (8.6%) with a median PFS of 36 months. There were no tumor-related deaths. G2 grading and the gastric primary tumor site were the only features significantly associated with the risk of recurrence of the disease (HR: 11.97 [95% CI: 1.22-116.99], HR: 12.54 [95% CI: 1.28-122.24], respectively). Tumor progression rarely occurs in patients with microscopic positive margin excision (R1) after endoscopic resection and does not seem to affect patients' clinical outcomes.

Leiomyosarcomas of large vessels are rare. It is a malignant tumour and the vast majority of these tumours arose from the inferior vena cava. We report a rare case of portal vein leiomyosarcoma, in a 56-years-old female patient admitted for chronic abdominal pain with abdominal mass in the right hypochondrium all evolving in a context of deterioration in general condition. We performed an abdominopelvic CT scan and then a MRI with contrast agent which objectified a large tissue mass containing areas of necrosis at the level of the duodeno-pancreatic compartment communicating at a large angle with the portal trunk over its entire length from the hepatic hilum to the spleno-mesenteric confluence responsible for a portal cavernoma downstream. This is associated with multiple secondary nodular tissue hepatic lesions. We also noted a respect for the fatty border separating the mass of the duodenal tract and the head of the pancreas, and also the absence of dilation of the pancreatic ducts making a pancreatic origin unlikely. To eliminate a duodenal origin of the mass we performed an upper digestive endoscopy which came back without any abnormality. An ultrasound-guided trans parietal biopsy of a secondary hepatic lesion was done and the pathological result of which speaks of a secondary hepatic lesion of a leiomyosarcoma.

A 77-year-old woman was referred to our hospital due to left upper abdominal pain, appetite loss and body weight loss for 1 month. Her past medical history was diabetes and intraductal papillary mucinous neoplasms (IPMNs). She had no fever and physical examination revealed mild tenderness in the left upper abdomen. Blood tests showed elevated inflammatory response with normal serum pancreatic enzymes. Contrast-enhanced CT showed marked swelling of the pancreatic tail, increased peripancreatic fatty tissue density, multiple IPMNs and obscuration of the enlarged main pancreatic duct at the tail. EUS showed there was no obvious mass in the pancreas and protein plug was suspected in the main pancreatic duct. EUS-FNA was performed and pathology showed no malignancy. ERCP showed discharge of purulent pancreatic fluid from the major duodenal papilla and stenosis of the main pancreatic duct at the tail. The culture of the purulent pancreatic fluid revealed Streptococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa, leading to diagnosis of acute obstructive suppurative pancreatic ductitis (AOSPD). Endoscopic nasopancreatic drainage and antimicrobial treatment were started. The inflammatory response improved rapidly and the patient was discharged 30 days after admission. To our knowledge, this is the second reported case of spontaneous AOSPD associated with IPMNs.

Periampullary cancers, including pancreatic ductal adenocarcinoma, ampullary-, cholangio-, and duodenal carcinoma, are frequently diagnosed in an advanced stage and are associated with poor overall survival. They are difficult to differentiate from each other and challenging to distinguish from benign periampullary disease preoperatively. To improve the preoperative diagnostics of periampullary neoplasms, clinical or biological markers are warranted.In this study, 28 blood plasma amino acids and derivatives from preoperative patients with benign (N = 45) and malignant (N = 72) periampullary disease were analyzed by LC-MS/MS.Principal component analysis and consensus clustering both separated the patients with cancer and the patients with benign disease. Glutamic acid had significantly higher plasma expression and 15 other metabolites significantly lower plasma expression in patients with malignant disease compared with patients having benign disease. Phenylalanine was the only metabolite associated with improved overall survival (HR = 0.50, CI 0.30-0.83, P < 0.01).Taken together, plasma metabolite profiles from patients with malignant and benign periampullary disease were significantly different and have the potential to distinguish malignant from benign disease preoperatively.

BACKGROUND
The primary duodenal gastrointestinal stromal tumor (GIST) is a rare type of gastrointestinal tract tumor. Limited resection (LR) has been increasingly performed for duodenal GIST. However, only a few studies reported minimally invasive limited resection (MI-LR) for primary duodenal GIST.
METHODS
The clinical data of 33 patients with primary duodenal GIST from December 2014 to February 2024 were retrospectively analyzed including 23 who received MI-LR and 10 who received laparoscopic or robotic pancreaticoduodenectomy (LPD/RPD).
RESULTS
A total of 33 patients with primary duodenal GIST were enrolled and retrospectively reviewed. Patients received MI-LR exhibited less OT (280 vs. 388.5min, P=0.004), EBL (100 vs. 450ml, P<0.001), and lower morbidity of postoperative complications (52.2% vs. 100%, P=0.013) than LPD/RPD. Patients received LPD/RPD burdened more aggressive tumors with larger size (P=0.047), higher classification (P<0.001), and more mitotic count/50 HPF(P=0.005) compared with patients received MI-LR. The oncological outcomes were similar in MI-LR group and LPD/RPD group. All the patients underwent MI-LR with no conversion, including 12 cases of LLR and 11 cases of RLR. All of the clinicopathological data of the patients were similar in both groups. The median OT was 280(210-480) min and 257(180-450) min, and the median EBL was 100(20-1000) mL and 100(20-200) mL in the LLR and the RLR group separately. The postoperative complications mainly included DGE (LLR 4 cases, 33.4% and RLR 4 cases, 36.4%), intestinal fistula (LLR 2 cases, 16.7%, and RLR 0 case), gastrointestinal hemorrhage (LLR 0 case and RLR 1 case, 9.1%), and intra-abdominal infection (LLR 3 cases, 25.0% and RLR 1 case, 9.1%). The median postoperative length of hospitalization was 19.5(7-46) days in the LLR group and 19(9-38) days in the RLR group. No anastomotic stenosis, local recurrence or distant metastasis was observed during the follow-up period in the two groups.
CONCLUSIONS
Minimally invasive limited resection is an optional treatment for primary duodenal GIST with satisfactory short-term and long-term oncological outcomes.

Observational Study
PURPOSE
The aim of the study was to test the established hypothesis that biopsies of spontaneous gastric perforations should be taken to rule out cancer.
METHODS
A prospective observational study was performed. Consecutive patients with spontaneous gastric perforation were included. Biopsies of the edges of the perforation were submitted for histological evaluation. The epithelial type as well as the nature of the pathology were evaluated.
RESULTS
Sixty-eight patients were included. Eight (12%) biopsies revealed duodenal origin. Sixty (88%) biopsies revealed gastric mucosa of which 33 (48%) could be specifically typed. All biopsies revealed benign ulceration. No malignancies were detected in these biopsies or on subsequent gastroscopic follow up.
CONCLUSION
This study suggests that routine intraoperative biopsy of gastric perforation may be questioned. Biopsy is probably better performed endoscopically after recovery.
