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.

Extra pancreatic manifestations of pancreatitis are rare, with a prevalence of 2-3%. One such rare manifestation is the triad of joint pain (polyarthritis), tender skin lesions (panniculitis), and pancreatic inflammation (pancreatitis), known as PPP. The pathogenesis of this phenomenon is not fully understood but is believed to involve lipolysis by pancreatic enzymes at lipid-rich skin and joint sites. PPP primarily affects middle-aged males with a history of alcohol use disorder. Diagnosis can be challenging due to the absence of typical abdominal symptoms. Delayed diagnosis may significantly worsen outcomes. Supportive therapy is the mainstay, but resolution requires addressing the underlying pancreatic abnormality. We present a case of a patient with a history of alcohol use disorder and recurrent acute pancreatitis who developed joint pain and skin rash. Extensive work-up ruled out other causes, and imaging and biopsy confirmed the diagnosis of PPP. Symptomatic management and treatment of the underlying pancreatic abnormality led to complete resolution of symptoms. Our case serves to raise awareness of this rare but potentially fatal syndrome.

Patients with Crohn's disease are at higher risk of opportunistic infection, especially if treated with immunosuppressive therapy. Cytomegalovirus has been reported to cause ulcerated lesions mainly in the lower gastrointestinal tract of inflammatory bowel disease patients. We herein report a rare case of Crohn's disease complicated with cytomegalovirus esophagitis, which was difficult to distinguish from exacerbation of Crohn's disease. Diagnostic values of clinical course, blood tests, endoscopic and histological examinations are limited but the present case was therapeutically diagnosed by antiviral therapy in combination with histological evidence of cytomegalovirus.

We report a case of a patient with distal bile duct cancer who presented with ocular pain and eye redness due to a liver abscess. The patient developed a liver abscess while waiting for surgery. Since Klebsiella pneumoniae with high viscosity was identified and imaging studies showed systemic infection, a diagnosis of klebsiella invasive syndrome was made. In addition, infectious intraocular inflammation was also observed at the same time. In addition to antibiotic therapy, vitrectomy and percutaneous transhepatic abscess drainage successfully normalized the inflammatory response and negative blood cultures were obtained. Thirty-four days after the start of treatment, surgery was performed and the postoperative course was uneventful, and the patient was discharged from the hospital on the 39th postoperative day. Forty-six months after that surgery, there has been no evidence of recurrence of cholangiocarcinoma or recurrence of infection, but unfortunately, vision loss in the right eye remains. Some Klebsiella pneumoniae are highly pathogenic and are often reported from Southeast Asia, and ocular pain and hyperemic symptoms are important physical findings.

Polyglycolic acid sheets and fibrin glue are routinely used in surgical procedures. Their usefulness in gastrointestinal endoscopy is mainly to prevent complications (bleeding, delayed perforation, stenosis, etc.) associated with procedures such as endoscopic submucosal dissection and endoscopic mucosal resection, with most reports on iatrogenic and secondary conditions. However, there are few reports on primary gastrointestinal diseases. Herein, we report three cases of gastrointestinal bleeding that were successfully treated with endoscopic hemostasis by sealing the lesions with polyglycolic acid sheets and fibrin glue. Case 1 was of an 83-year-old woman with a rare duodenal perforation that was treated with omental plugging who experienced subsequent bleeding from the greater omentum. Case 2 was of a 73-year-old woman with an acute hemorrhagic rectal ulcer that was difficult to treat even after performing standard endoscopic hemostasis techniques; however, surgery was avoided by sealing. Case 3 was that of an 89-year-old woman with a stercoral ulcer, treated curatively using a combination of sealing and argon plasma coagulation right from presentation based on the lessons learned from Cases 1 and 2. Endoscopic hemostasis using a polyglycolic acid sheet and fibrin glue may be a new treatment option for gastrointestinal bleeding particularly in refractory or rare causes.

Avascular necrosis (AVN) is linked to considerable morbidity, resulting in severe pain and functional impairment. Herein, for the first time, we reported an 18-year-old patient with Crohn's disease during the remission phase under Azathioprine therapy who presented with articular pain. Although no underlying risk factors, the patient was diagnosed with severe AVN of the bilateral femoral head and both knees simultaneously following pain in involved areas. This case highlights the importance of demand multidisciplinary approach to chronic disease. Moreover, clinicians should be aware of articular manifestations in IBD patients to diagnose and treat these conditions as soon as possible. Patients should be evaluated for their psychologic, gastrointestinal, and extra-gastrointestinal comorbidities during each follow-up visit.

A 72-year-old man was referred to our hospital for the examination of a pancreatic head mass. Abdominal computed tomography revealed a contrasted 8-cm-diameter tumor extending from the dorsal pancreatic head to the porta hepatis. The preoperative diagnosis was challenging due to the absence of specific imaging findings and the inability to perform a biopsy. Positron emission tomography/computed tomography and diffusion-weighted imaging suggested a malignant tumor originating from the organs surrounding the pancreatic head. Subtotal stomach-preserving pancreaticoduodenectomy with regional lymph node dissection was performed, as dissection from the pancreatic head proved unfeasible. Pathological examination identified the tumor as an enlarged lymph node consisting of pleomorphic large cells forming clusters, positive for follicular dendritic cell markers cluster of differentiation (CD) 21 and CD23. No evidence of tumor capsule infiltration, other organ infiltration, or metastasis to other lymph nodes was observed. The final diagnosis was nodal follicular dendritic cell sarcoma (FDCS) originating from the pancreatic head lymph nodes. No recurrence occurred at 3 years postoperatively with no postoperative treatment. Intraperitoneal nodal FDCS is extremely rare, and occasionally, it can lead to postoperative recurrence and progression. It is crucial to differentiate neoplastic lymph node enlargement around the pancreatic head from nodal FDCS.

An 81-year-old woman who underwent laparoscopic-assisted low anterior resection with instrumented anastomosis using the double stapling technique for rectal cancer 5 years ago was found to have an enlarged anastomotic mass on computed tomography. On colonoscopy, the anastomotic mass was observed as a 30-mm-sized subepithelial lesion, which was presumed to be the submucosa on endoscopic ultrasonography (EUS). EUS-guided fine-needle aspiration was performed; however, no cellular components were collected. Therefore, endoscopic submucosal dissection (ESD) was performed to remove the entire anastomotic mass. However, any lesion in the submucosa was not detected during ESD, and the lesion was suspected to be located deeper than the submucosa. Therefore, EUS was performed from the muscule layer just below the dissected submucosa, and the mass was detected outside the muscle layer in contact with the rectal wall. Upon endoscopic incision of the muscle layer, milky white mucus was excreted into the rectal lumen. Subsequently, the scope was advanced to an area outside the muscle layer where the mass was located, which was a closed lumen with mucus retention. Surface biopsy of the closed lumen revealed normal colonic mucosa. Therefore, the subepithelial lesion was diagnosed as an implantation cyst arising outside the rectal wall.
