Incomplete resection of choledochal cysts (CCs) that extend deep into the pancreas can lead to protein plug or stone formation, pancreatitis, and cholangiocarcinoma. We encountered two cases of choledocholithiasis in remnant intrapancreatic CCs, in which the patients exhibited symptoms after 3 and 21 years of cyst excision. A 21-year-old woman who had undergone excision of a CC, as a neonate, p...

BACKGROUND A modified Blair's incision or standard facelift incision is recommended to remove tumors in the accessory parotid gland. These incisions frequently result in long and visible scars. Therefore, the authors have introduced an endoscopic approach via a small preauricular incision to achieve excision of benign tumors in the accessory parotid gland. METHODS The endoscopic surgical tech...

Recently, increasingly invasive therapeutic endoscopic procedures and more complex gastrointestinal surgeries such as endoscopic mucosal resection, endoscopic submucosal dissection, and novel laparoscopic approaches have resulted in endoscopists being confronted more frequently with perforations, fistulas, and anastomotic leakages, for which nonsurgical closure is desired. In this article, we p...

We report a rare case of pleomorphic adenoma arising from the lateral nasal wall which was incidentally detected at a very early stage. A 38-year-old man presented to the ophthalmology department with a 2-year history of epiphora from the left eye. He was referred to otorhinolaryngology department as a candidate for endoscopic dacryocystorhinostomy. Nasal endoscopy revealed a polypoid mass on t...

Objective. Mesorectal excision corresponding to the location of a tumor, termed tumor-specific mesorectal excision (TSME), is commonly performed for resection of upper rectal cancer. We devised a new laparoscopic procedure for sufficient TSME with rectal transection followed by mesorectal excision. Operative Technique. After mobilization of the sigmoid colon and ligation of inferior mesenteric ...

Pleomorphic adenomas originating from the minor salivary glands are rare in the nasal cavity. Total surgical excision is the preferred treatment for pleomorphic adenomas. Lateral rhinotomy, midfacial degloving, transpalatal surgery and endoscopic surgery are among the surgical approaches. Endoscopic tumor removal produces less morbidity, reduces blood loss during surgery, decreases hospital sta...

Upper urinary tract urothelial carcinoma (UTUC) is relatively uncommon. Radical nephroureterectomy with an ipsilateral bladder cuff excision has been the gold standard treatment for UTUC. However, recent advances in technology have made possible the increased use of endoscopic management for the treatment of UTUC. The definitive goal of endoscopic management of UTUC is cancer control while main...

Mismatch repair (MMR) testing is recommended in the Netherlands for all patients under 70 years of age with newly diagnosed colorectal cancer (CRC) order to identify Lynch syndrome. T1 CRC can be removed by local excision or oncological surgical resection. We evaluated frequency MMR pT1 lesions within Dutch screening cohort. population-based program from 2016–2018 were identified pathology regi...

Introduction: The leiomyoma of the urethra is rare. It a benign mesenchymal tumor that affects smooth muscle urethra. These tumors often occur in women childbearing age middle their appearance about 41 years old. Case report: Here we report case 37 old white woman with progressive dysuria nodule sensation vagina Conclusions: Leiomyoma tumor, common uterus but very rare His diagnosis rarely ment...
