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.

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.

Project description:INTRODUCTION:Totally endoscopic mitral valve repair (TEMVR) is the highest level of minimally invasive cardiac surgery (MICS). It brings many benefits to patients but the downside is that a robotic system is always required. The deployment of robotic surgery is very complicated and expensive. Therefore, we improvised, making it possible to perform TEMVR without the aid of a robotic system. PRESENTATION OF CASE:A 66-year-old male patient presented with severe mitral valve regurgitation due to posterior leaflet prolapse. He was treated with TEMVR without robotic assistance. No chest incision was over 1.2 cm. The repair techniques included posterior leaflet resection and annuloplasty with ring implantation. DISCUSSION:A midline sternotomy is still the standard approach for mitral valve repair. In recent years, MICS has gradually replaced conventional surgery with the most advanced strategy being totally robotic mitral valve repair. However, complex surgical techniques and high cost make it less accessible for the majority of patients. Instead of using robot, we improved mitral valve exposure techniques, surgical port placement and therefore were able to perform TEMVR with MICS instruments. CONCLUSION:TEMVR without robotic assistance is a safe, effective and cost-efficient procedure, which can be adopted in most cardiac centers.

Project description:Objective: Endoscopic resection (ER) is more difficult and has a higher rate of complications, such as perforation and bleeding. The aim of this study was to evaluate the safety and feasibility of a bipolar polypectomy snare for ER. Methods: Initial ER procedures in live pigs were carried out. Then, a human feasibility study was performed in patients with colorectal polyps. Finally, the finite element method was used to evaluate the safety and effectiveness of the new bipolar snare. Results: In the live animal model, there were no significant differences in wound size and cutting time between monopolar and bipolar groups. The histological results (histological scores) of the two groups in porcine experiments were almost the same except that the incision flatness of bipolar group was better than that of the monopolar group. Incidence of bleeding and perforation was similar between the two groups in pigs' and patients' study. At last, the finite element model showed that the vertical thermal damage depth produced by bipolar snare system was approximately 71-76% of that produced by monopolar snare system at the same power. Conclusions: The novel bipolar snare is feasible in patients with colorectal polyps and can be an alternative choice for ERs.

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.

Project description:The usual etiologies of giant abdominal cystic masses in infants are mesenteric cyst, enteric duplication cyst, ovarian cyst in females, cystic lymphangioma, however, the presentation of a choledochal cyst in a gigantic form, is unusual. The primary modality for diagnosis of this entity is ultrasound, followed by MRI. The characteristic ultrasound features of a choledochal cyst are a well-defined cystic lesion which may be found to replace any segment of the biliary tree and is distinctly separate from the gallbladder. The associated anomalies are biliary atresia, gallbladder atresia, hepatic fibrosis and those of the pancreatico-biliary ductal system. MRI with MRCP has a conclusive role in confirming the ultrasound diagnosis. Choledochal cysts are currently classified as proposed by Todani et al, into five types. Herein, we report the case study of a 4-month-old male infant afflicted with a gigantic, Type1 Choledochal cyst, complicated by perforation, which was diagnosed by us at the first instance itself, using ultrasound examination and confirmed by MRI. The diagnosis was further confirmed at surgery and histopathology. The recommended treatment of cyst resection accompanied by a hepatico-jejunostomy bypass procedure, was successfully performed in the reported infant.

Project description:BACKGROUND:Choledochal cysts are divided into 5 types. Physicians believe that Caroli disease (which refers to type V biliary cysts) is a special type of biliary cyst caused by a mutation in the PKHD1 gene and is associated with autosomal recessive polycystic kidney disease (ARPKD). There is currently no clear association between other types of choledochal cysts and polycystic kidney disease. CASE PRESENTATION:We report a 65-year-old male patient with jaundice, decreased appetite, and itchy skin. His biochemistry test results indicated obstructive jaundice disease. Cross-sectional imaging showed a type IVA choledochal cyst accompanied by autosomal dominant polycystic kidney disease (ADPKD). Due to economic difficulties, the patient achieved percutaneous transhepatic cholangial drainage (PTCD) instead of surgery. CONCLUSION:To our knowledge, this is the second case report of the coexistence of type IVA choledochal cysts and ADPKD. We conclude that it is vital to be aware that the above condition is a possibility. This case report will aid earlier diagnosis and management and possibly prevent further damage to liver and kidney function.
