Project description:Sistrunk procedure is the standard method for thyroglossal duct cyst resection. While this procedure is successful and safe, it results in postoperative scars on the front of neck. We propose a total transoral technique without external incision that starts with careful separation of the floor of the mouth and genioglossus muscle followed by the exact localization of the cyst using methylene blue. Simultaneously, the hyoid bone connected to the cyst and tract was removed. Finally, routine hemostasis is conducted, and the operative cavity is closed. All patients who received this operation in our department recovered successfully without experiencing severe intraoperative or postoperative complications.

Development of intrahepatic cholangiocarcinoma at the remnant intrahepatic cyst portion 10 years after resection of type IV choledochal cyst.

Project description:Complete resection of Todani type IV choledochal cyst (CC) is not possible, because the intrahepatic portion is not resectable. We present a case of intrahepatic cholangiocarcinoma that arose from the remnant CC portion that was located within the liver 10 years after resection. A 59-year-old female patient had undergone resection of type IV CC 10 years ago, leaving large remnant portions of CC at the liver and pancreas. Two and four years after resection of the extrahepatic CC, cholangitis with intrahepatic stones developed hence these episodes were treated with percutaneous transhepatic cholangioscopy. Ten years after the first operation, intrahepatic stones and a new mass were identified in follow-up imaging studies. Because the mass was identified as adenocarcinoma on biopsy, we performed left hepatectomy with redo hepaticojejunostomy. Pathologic examination showed a 4.5-cm-sized moderately differentiated adenocarcinoma arising from the remnant CC with lymph node metastasis. The patient recovered uneventfully and is currently undergoing adjuvant chemotherapy. Our case indicates that the remnant intrahepatic CC can undergo malignant transformation long after resection of CC. Since the intrahepatic CC portion in type IV CC is usually unresectable, wide hepaticojejunostomy and life-long observation with regular imaging study follow-up are highly recommended for prevention and early detection of malignant transformation.

Resection depth for small colorectal polyps comparing cold snare polypectomy, hot snare polypectomy and underwater endoscopic mucosal resection.

Project description:Background and study aims Small colorectal polyps are removed by various methods, including cold snare polypectomy (CSP), hot snare polypectomy (HSP), and underwater endoscopic mucosal resection (UEMR), but the indications for using these methods are unclear. We retrospectively assessed the efficacy of CSP, HSP, and UEMR for small polyps, focusing on the depth of the resected specimens. Patients and methods Outpatients with non-pedunculated small polyps (endoscopically diagnosed as 6 to 9 mm), resected by two endoscopists between July 2019 and September 2020, were enrolled. We histologically evaluated the specimens resected via CSP, HSP, and UEMR. The main outcome was the containment rate of the muscularis mucosa (MM) and submucosa (SM) tissues. Results Forty polyps resected via CSP (n = 14), HSP (n = 12), or UEMR (n = 14) were enrolled after excluding 13 polyps with resection depths that were difficult to determine. The rates of specimens containing MM and SM tissue differed significantly (57 % and 29 % for CSP, 92 % and 83 % for HSP, and 100 % and 100 % for UEMR, respectively ( P = 0.005 for MM and P < 0.001 for SM tissue). Multiple logistic regression analysis showed UEMR was an independent factor relating to the containment of SM tissue. The thickness of SM tissue by CSP, HSP, and UEMR were 52 μm, 623 μm, and 1119 μm, respectively ( P < 0.001). The thickness by CSP was significantly less than those by HSP and UEMR ( P < 0.001, Bonferroni correction). Conclusions UEMR could be the best method to contain SM tissue without injection. Further studies are needed to evaluate the indication of UEMR for small polyps.

Endoscopic Resection of Lateral Synovial Cyst of the Knee.

Project description:Synovial cysts on the lateral side of the knee can cause pain, limitation of joint mobility, compression of the neighboring neurovascular structures, rupture leading to compartment syndrome, infection, erosion of adjacent bone, and iliotibial band friction syndrome. Open resection is commonly performed for symptomatic cysts. We describe an alternative, endoscopic approach to cyst resection. This has the advantages of minimally invasive surgery of smaller wounds, better cosmesis, and less surgical trauma.

Type I choledochal cyst. Total laparoscopic resection and Roux-en-Y reconstruction to two separated ducts.

Project description:A choledochal cyst is a rare condition that requires surgical treatment to prevent complications, such as obstructive jaundice, cyst rupture, cholangitis, and the risk of malignancy. Complete cyst excision is considered the best option, as it reduces the risk of inflammation and the development of cholangiocarcinoma. Therefore, cholecystectomy and complete cyst resection followed by reconstruction with a Roux-en-Y hepaticojejunostomy is the treatment of choice. We present a case (with video) that shows the complete resection of a type I choledochal cyst with Roux-en-Y reconstruction of two separate ducts since the right posterior duct reached the cyst independently. The laparoscopic approach offers all the advantages of mini-invasive surgery and better visualization of the structures; however, biliary reconstruction to fine ducts implies a surgical challenge that requires high training in mini-invasive surgery.

Laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy.

Project description:Congenital choledochal cysts are rare in adults. Due to the risk of developing cholangiocarcinoma, the current standard of care is complete excision of the cyst and reconstruction with hepaticojejunostomy. So far, more than 200 laparoscopic resections have been reported in adults, the majority being from Far Eastern countries over the last five years. Herein, the technique of laparoscopic type I choledochal cyst excision and hepaticojejunostomy is presented in a 37-year-old male with an accompanying video. The advantages of laparoscopic surgery are applicable for choledochal cyst excision as well. We believe that teamwork, expertise on intracorporeal suturing and hepatobiliary surgery are central issues for this operation.
