Project description:Popliteal cysts, often referred to as Baker's cysts, are a common occurrence in the adult knee. Although controversy exists as to the exact indications for treatment, these structures can cause extreme discomfort and morbidity, including pain from rupture and symptoms from neurovascular compromise. Prior to the development of the arthroscope, open treatment of popliteal cysts was not uncommon. Complications such as poor wound healing, cyst recurrence, and knee flexion contractures were reported after such treatment. Owing to the presence of a valve-type structure, also called the posterior transverse synovial infold, there is 1-way flow of synovial fluid into the cyst. Although seldom described, there is a reproducible and relatively straightforward arthroscopic treatment for this pathology. This technical report will describe the arthroscopic treatment of popliteal cysts and clarify the posterior knee anatomy that gives the surgeon the landmarks to perform safe and effective arthroscopic treatment of popliteal cysts.

Project description:Background/objectiveSpinal arachnoid cysts (SAC) are intradural lesions, which may provoke a compression of the spinal cord and roots. Endoscopic techniques are increasingly used to minimize the surgical access and the postoperative scar tissue. Shunts may also represent an option. The aim of this paper is to illustrate the technique of endoscopic-assisted fenestration and positioning of a cysto-peritoneal diversion in a thoracic SAC using a flexible endoscope and to perform a systematic literature review on this subject.Material and methodsWe reported our case and we performed a review of the literature, searching for all the adult cases of Type III SACs in English language treated through endoscopic procedures.ResultsWe found 5 articles matching our search criteria and we included 9 adult patients in our analysis. Six patients were females and the most common localization was the thoracic spine. Six patients underwent selective laminectomies followed by endoscopic fenestration without cyst wall resection. Three patients had a percutaneous endoscopic inspection of the cyst and in two cases a cysto-subarachnoid shunt space was performed. Improvement of pre-operative neurological deficit was reported in six patients, no patients experienced clinical deterioration. The mean follow-up was 22 months and no progression or recurrence was reported.ConclusionThe implementation of endoscopy allows a minimally invasive treatments with good visualization of cyst anatomy and precise shunt positioning under real-time guidance. Endoscopy is technically demanding but it can offer similar clinical outcomes when compared to microscopic procedures with a limited rate of post-operative complications.The long-term risk of recurrence should be established by prospective studies.

Project description:When treating a popliteal cyst in the knee joint, it is often necessary to simultaneously treat the intra-articular lesions so as to reduce the recurrence of the cyst after the operation. Herein, we propose an arthroscopic resection technique for popliteal cyst, in which the position of the popliteal cyst is indirectly located by finding out the location of the semimembranosus tendon during the operation, thereby completing the arthroscopic resection of the popliteal cyst. This method does not involve the posteromedial compartment of the knee joint. Arthroscopic treatment can be performed on the combined intra-articular lesions through anteromedial and anterolateral approaches before or after popliteal cyst resection. Technique Video Video 1 This is a patient with a right popliteal cyst. After the operative approach was established according to step 2, the arthroscope was implanted through approach 1, and a motorized shaver was implanted through approach 2. We clean the surrounding soft tissue to look for the semimembranosus tendon, and the popliteal cyst will be found on the lateral side of the semimembranosus tendon. Finally, we cleaned the cyst wall tissue completely.

Project description:BackgroundAlthough aneurysmal bone cysts (ABCs) are benign tumours, they have the potential to be locally aggressive. Various treatment approaches, such as en bloc resection, open curettage, radiotherapy, sclerotherapy, and embolization have been proposed, but the most appropriate treatment should be selected after considering the risk of tumour recurrence and treatment complications. Endoscopic curettage (ESC) may be a less invasive alternative to open curettage for ABC treatment. We aimed to describe the use of ESC for the treatment of ABCs and to report our clinical outcomes, including the incidence rate of recurrence, radiological appearance at final follow-up, time to solid union, complications, and postoperative function.MethodsBetween 1998 and 2015, 30 patients (18 men and 12 women; mean age, 17.4 years) underwent ESC for the treatment of primary ABCs at our hospital (mean postoperative follow-up, 55 months). ESC was performed under arthroscopic guidance for direct visualization, and curettage extended until normal bone was observed in the medullary cavity. To investigate bone healing after ESC, we evaluated the consolidation of cysts at the final evaluation (based on the modified Neer classification) and time to solid union after surgery, which was defined as sufficient cortical bone thickness to prevent fracture and allow physical activities.ResultsRecurrence was identified in 3 cases (10%). Curative outcomes were obtained after repeated ESC or open curettage. A log-rank analysis indicated that age < 10 years (p = 0.004) and contact of the tumour with the physis (p = 0.01) increased the risk of tumour recurrence. Residual tumours were identified in 9 cases (30%); these lesions remained inactive over the extended follow-up period. The average time to solid union after endoscopic curettage was 3.2 months. Transient radial nerve palsy was identified in 1 case. Good postoperative functional recovery occurred in all cases.ConclusionsESC is a minimally invasive technique for the treatment of ABCs, and the tumour recurrence rate is comparable to that of other standard procedures. However, the application of this method should be carefully considered, especially for patients < 10 years and when the tumour comes in contact with the physis.

Project description:GoalsTo examine the utility of integrated molecular pathology (IMP) in managing surveillance of pancreatic cysts based on outcomes and analysis of false negatives (FNs) from a previously published cohort (n=492).BackgroundIn endoscopic ultrasound with fine-needle aspiration (EUS-FNA) of cyst fluid lacking malignant cytology, IMP demonstrated better risk stratification for malignancy at approximately 3 years' follow-up than International Consensus Guideline (Fukuoka) 2012 management recommendations in such cases.StudyPatient outcomes and clinical features of Fukuoka and IMP FN cases were reviewed. Practical guidance for appropriate surveillance intervals and surgery decisions using IMP were derived from follow-up data, considering EUS-FNA sampling limitations and high-risk clinical circumstances observed. Surveillance intervals for patients based on IMP predictive value were compared with those of Fukuoka.ResultsOutcomes at follow-up for IMP low-risk diagnoses supported surveillance every 2 to 3 years, independent of cyst size, when EUS-FNA sampling limitations or high-risk clinical circumstances were absent. In 10 of 11 patients with FN IMP diagnoses (2% of cohort), EUS-FNA sampling limitations existed; Fukuoka identified high risk in 9 of 11 cases. In 4 of 6 FN cases by Fukuoka (1% of cohort), IMP identified high risk. Overall, 55% of cases had possible sampling limitations and 37% had high-risk clinical circumstances. Outcomes support more cautious management in such cases when using IMP.ConclusionsAdjunct use of IMP can provide evidence for relaxed surveillance of patients with benign cysts that meet Fukuoka criteria for closer observation or surgery. Although infrequent, FN results with IMP can be associated with EUS-FNA sampling limitations or high-risk clinical circumstances.

Project description:Thyroglossal duct cyst is the most common congenital neck mass in children and young adults. The authors present two cases affecting two patients aged 7 and 9 years, respectively, who had a palpable painless swelling in the submental region. In both patients ultrasound (US) examination showed an anechoic or hypoechoic rounded mass with well-defined margins thus confirming clinical suspicion of thyroglossal duct cyst. One patient also had a second, deep-lying, nonpalpaple cyst which communicated with the superficial cyst. These cases are typical and confirm that US is essential in suspected thyroglossal duct cyst to confirm clinical diagnosis, detect lesions which are not clinically appreciable due to their small size or deep location, to assess communication between the lesions and to detect possible complications.Thyroglossal duct cyst is the most common congenital neck mass in children and young adults.

Project description:Background and Importance. Sellar arachnoid cysts and Rathke's cleft cysts are benign lesions that produce similar symptoms, including optochiasmatic compression, pituitary dysfunction, and headache. Studies have reported the use of various surgical treatment methods for treating these symptoms, preventing recurrence, and minimizing operative complications. However, the postoperative cerebrospinal fluid (CSF) fistula and recurrence rate remain significant. Clinical Presentation. In this paper, we present 8 consecutive cases involving arachnoid cysts and Rathke's cleft cysts, which were managed by using drainage and cisternostomy, the intentional fenestration of the cyst into the subarachnoid space, and then meticulously closing sellar floor using dural sutures. The postoperative images, CSF fistula rate, and the recurrence rate were favorable. Conclusion. We report this technique and discuss the benefit of this minimally invasive approach.

Project description:Tuberculosis of the musculoskeletal system is uncommon and constitutes 1% to 5% of all forms of tuberculosis. In total, 30% of skeletal tuberculosis involves the joints, the knee being the third most commonly affected after the spine and the hip. Knee tuberculosis commonly presents as synovitis or arthritis, and infected Baker's cyst is a rather rare presentation. It is believed to result from the propagation of tuberculosis of the knee joint into the cyst, as approximately one half of the Baker's cyst communicates with the knee joint and it appears as swelling in the medial aspect of the popliteal fossa. For tuberculous popliteal bursitis at the lateral aspect of the popliteal fossa, it may be an extra-articular extension of tuberculosis of the knee joint via the popliteal hiatus. Chemotherapy remains the cornerstone of treatment; surgery is indicated in recalcitrant cases. In this Technical Note, the technical details of endoscopic resection of recalcitrant tuberculous bursitis at the lateral aspect of the popliteal fossa are described. This minimally invasive technique has the advantage of better cosmetic results and fewer wound complications and reduces the extent of surgical dissection as compared with open surgery.

Project description:BackgroundThe management of complicated symptomatic pineal cysts in the pediatric population is challenging and variable. Surgical management may include treatment of hydrocephalus alone, or direct treatment of the cyst with or without direct hydrocephalus management. This is typically done through craniotomy-based microsurgical approaches to the pineal region or an endoscopic transventricular approach.MethodsWe present a stepwise minimally invasive technique to treat complicated pineal cysts in young children associated with an obstructive hydrocephalus in a single procedure through third ventriculostomy combined with an intraventricular marsupialization of the pineal cyst through a single burr-hole using stereotactic navigation.ResultsTwo young patients with over 2 years of follow-up have done well without complication using this technique. Other literature reports for complex pineal cysts in pediatric patients are reviewed and this technique is not previously described for this population.ConclusionEndoscopic third ventriculostomy and cyst marsupialization using a single burr-hole and stereotactic navigation for symptomatic or enlarging pineal cysts in children allow for minimally invasive management, a rapid recovery, short hospital stay, and durable outcome owed to redundant CSF flow pathways.

Project description:Although most of the parameniscal cysts are very small and asymptomatic, some of them can present with a painful mass or snapping knee. Because parameniscal cysts are almost always associated with horizontal meniscal tears, arthroscopic partial meniscectomy of the involved part of meniscus and intra-articular cyst drainage has become the most accepted procedure. However, arthroscopic cyst decompression through partial meniscectomy to the meniscocapsular junction to expose the communication between the cyst and the knee joint may sacrifice some of the healthy parts of the meniscus especially when meniscal tear is peripheral. Moreover, internal drainage may not be an adequate treatment for a cyst larger than 5 cm in size or a multiloculated cyst. The excision of the cyst is a more appropriate treatment option in these situations. The purpose of this Technical Note is to describe the details of endoscopic resection of medial extra-articular cysts of the knee. This technique is indicated in symptomatic medial extra-articular cysts of the knee with peripheral or no tear of the medial meniscus, especially if the cysts are large and multiloculated.
