[Ab] Abstract:OBJECTIVES: The endoscopic approach increasingly is used to treat third ventricular colloid cysts. Our objective was to assess the results of endoscopic resection of colloid cysts of the third ventricle. METHODS: A retrospective study was designed, and a series of 112 consecutive patients (76 male, 36 female) with third ventricular colloid cyst treated by endoscopic surgery was undertaken. RESULTS: We found that the most common clinical presentations in patients with third ventricular colloid cyst were headache, vomiting, and impaired vision. Complete resection was obtained in majority of patients (92%). Meningitis, hemiparesis, and memory deficits occurred most commonly as postoperative complications. CONCLUSIONS: High rates of complete resection of third ventricular colloid cysts, with low morbidity and mortality, are possible with an endoscopic approach. The results of this study support the role of endoscopic resection in the treatment of patients with third ventricular colloid cysts as a safe and effective modality and show how endoscopic resection of third ventricular colloid cysts can produce favorable results.

[Ab] Abstract:INTRODUCTION: Colloid cysts are uncommon lesions in the pediatric age group, which most commonly occur in the fourth through fifth decades. The authors hereby report a series of 36 patients with colloid cysts in the pediatric age group. MATERIAL AND METHOD: A retrospective chart review was conducted on all patients with colloid cyst who underwent surgery in our institute between November 2003 and December 2016 (13 years). Patients above the age of 18 were excluded from the study. They were analyzed based on clinical presentation, radiological findings, surgical approaches, and outcome. RESULTS: There were 36 pediatric patients selected for the study. Age ranged from 8 to 18 years. The male-to-female ratio was 3.5:1. Headache and vomiting were the most common symptoms, and papilledema is the most common clinical sign. The mean duration of symptoms was 9 months (range 1 day to 5 years), but 27 (75%) of the children had precipitous symptoms just before presentation. Preoperative CT showed a hyperdense non-enhancing lesion in the majority of cases. Endoscopic excision was done in 13; 5 patients underwent transcortical transventricular excision, while transcallosal approach was opted for in 17 patients. In one patient, the colloid cyst could not be removed endoscopically and had to be converted to transcortical transventricular approach. Postoperatively, five patients developed CSF leak. They were successfully managed conservatively. One patient had operative site extra dural hematoma and underwent re-exploration, and two patients had transient hemiparesis which improved spontaneously. The median follow-up period was 9 months in the 30 available patients. Though no formal neuropsychological testing was done at follow-up, all children appeared to be doing well without memory disturbances. CONCLUSION: Pediatric colloid cysts are less common and may show rapid deterioration. Timely surgery results in a permanent cure with minimum morbidity. The results of either micro neurosurgical or endoscopic operative excision of colloid cysts in children are excellent. All children who are symptomatic with raised intracranial pressure due to a third ventricular colloid cyst should undergo definitive surgery. There were no major permanent deficits in memory or disconnection syndromes observed with the limited anterior colostomy.

[Ab] Abstract:INTRODUCTION: Brain retraction is often required to develop a surgical corridor during the resection of deep-seated intracranial lesions. Traditional blade retractors distribute pressure asymmetrically and may case local tissue damage. Tubular retractors minimize this pitfall by distributing pressure evenly, which has been shown to translate to significant safety and efficacy data. Further qualified reports regarding the use of tubular retractors are of interest. METHODS: We performed a retrospective analysis of 1 surgeon's experience with 20 cases of minimally invasive resection with the ViewSite Brain Access System (n = 7) and BrainPath (n = 13) systems. In addition, a comprehensive review of all published cases of tubular retractor systems used for resection of subcortical neoplastic, cystic, infectious, vascular, and hemorrhagic lesions was conducted. RESULTS: Of the 20 cases analyzed, gross total resection was achieved in 18, with an associated 10% immediate postoperative complication rate and 5% long-term complication rate. A comprehensive review of the literature showed 30 articles describing 536 cases of resection of deep neoplastic or colloid cysts with an overall complication rate of 9.1%. CONCLUSIONS: Tubular retractor systems have a favorable safety profile and are an important tool in the armamentarium of a neurosurgeon for the resection of deep intracranial lesions.

[Ab] Abstract:Most pancreatic ductal adenocarcinomas (PDAs) show solid growth pattern, but ductal adenocarcinomas may demonstrate intratumoral cystic appearance or accompany peritumoral non-neoplastic cystic lesions, thus mimicking cystic pancreatic tumors on imaging studies. The histopathologic findings for PDA with cystic feature are divided into neoplastic and non-neoplastic cysts. Neoplastic cystic changes include large-duct type cysts (microcystic appearance), neoplastic mucin cysts (macrocystic appearance), colloid carcinomas (mucinous noncystic adenocarcinomas), and degenerative cystic change usually caused by hemorrhagic necrosis of tumor. Non-neoplastic cystic changes include retention cysts caused by ductal obstruction and pseudocysts caused by tumor-associated pancreatitis. Depending on the presence, size, number, and configuration of cystic changes, PDA should be differentiated from various types of cystic neoplasms. This pictorial essay provides histopathologic classification of PDAs with cystic features along with the corresponding cross-sectional imaging findings, and their differential diagnosis.

[Ab] Abstract:Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has been widely used for diagnosis of both inflammatory and tumor lesions located in and adjacent to the gastrointestinal tract. EUS-FNA has been considered to be a safe technique with few complications, as shown in recent review articles in which EUS-FNA-related morbidity and mortality rates were reported to be <1%. It should be noted, however, that needle tract seeding, although uncommon, can occur after diagnostic EUS-FNA and that this complication affects the prognosis of patients. Although an accurate value for the frequency of needle tract seeding caused by EUS-FNA has not been reported, the numbers of case reports on needle tract seeding have been rapidly increasing, especially in Japan. These case reports regarding EUS-FNA-related needle tract seeding prompted us to reevaluate the safety of EUS-FNA because this complication may have a significant influence on patients' prognoses. In this review, we summarize the clinical features and outcomes of needle tract seeding after EUS on the basis of the previously reported cases and provide useful information to prevent and reduce this serious complication.

[Ab] Abstract:OBJECTIVE: To discuss the clinical presentation, pathological diagnosis, and surgical outcome for a series of 42 consecutive patients treated for lateral and third ventricular tumors. METHODS: This is a retrospective series study conducted between 2001 and 2015 and included 42 patients (mean age: 25 years; range: 2 months-65 years) with lateral and third ventricle tumors surgically treated at King Khaled University Hospital, Riyadh, Kingdom of Saudi Arabia. Demographic, clinical, radiological, surgical, histopathological, and follow up data were analyzed. RESULTS: The most common symptoms at presentation included headache (69%), nausea/vomiting (38%), visual deficits (24%), and seizures (17%). Lesions were located in the lateral ventricle in 15 patients, third ventricle in 20 patients, and involved both the lateral and third ventricles in 7 patients. The most common tumor types in the overall cohort were colloid cysts (n=6) and pineal tumors (n=6). The postoperative complication rate was 36%. The most common postoperative complications were seizure and hydrocephalus (n=5 each, 12%). Surgical mortality was 5%. CONCLUSION: The selection of the surgical approach for intraventricular tumor resection is fundamentally dependent on the surgeon`s experience and preference. We recommend that this decision be based on the anatomic considerations that provide the best and safest access to the mass, rather than on the risk of seizure following transcortical approach.

[Ab] Abstract:Colloid cysts are benign lesions, found in the anterior part of the roof of the third ventricle. A PubMED search of literature was performed to identify the evidence on different treatment options and surgical approaches for removal of colloid cysts. Evidence on endoscopic versus microsurgical resection of colloid cysts showed that microsurgical approach had significantly higher rates of gross total resection, lower recurrence rate and lower re-operation rate. No significant difference with respect to the mortality rate or the need for a shunt was found between the two groups. However, the overall morbidity rate was lower for the endoscopic group. .

[La] Language:eng
[Ab] Abstract:INTRODUCTION: Acquired Chiari malformation and associated syringomyelia have been previously described following lumbar puncture/drainage, lumboperitoneal shunts, and spontaneous cerebrospinal fluid leakage. In addition to these etiologies, space-occupying lesions such as meningiomas, epidermoid cysts, medulloblastomas, and arachnoid cysts are rare causes of acquired Chiari malformation and syringomyelia. We report a rare case of colloid cyst with hydrocephalus causing secondary Chiari malformation with syringomyelia. CASE REPORT: A 58-year-old lady presented with neck pain and difficulty in walking and numbness of all 4 limbs of 1-year duration. Diagnostics with magnetic resonance imaging of the head and the cervical spine were done in the referring hospital. The patients was then referred with the diagnosis of colloid cyst with hydrocephalus and Chiari malformation 1 with cervicodorsal syringomyelia. She underwent colloid cyst excision through the transcallosal approach. Postoperatively the patient showed improvement in her symptomatology. Magnetic resonance imaging of the brain and cervical spine at 6 months' follow-up showed resolved Chiari malformation and resolving syrinx. CONCLUSIONS: Colloid cyst with hydrocephalus is a rare cause of secondary Chiari malformation with syringomyelia. Surgical management of the underlying lesion improves acquired Chiari malformation and associated syringomyelia.

[Ab] Abstract:OBJECTIVE: To accurately describe patient characteristics and the clinical presentation of fatal colloid cysts. METHODS: A systematic literature search of 3 popular databases was performed. Inclusion criteria were individuals with sudden-onset death and colloid cysts identified on imaging and/or autopsy. The cause of death must have been ascribed to the colloid cyst to be eligible for data extraction. Deaths precipitated by lumbar puncture were excluded. Clinical data were extracted and descriptive statistics were ascertained. Subgroup analyses were performed to compare adults with pediatric patients. RESULTS: A total of 107 patients were included in the quantitative synthesis. The mean age was 28.5 years (standard deviation 13.3, range 6-79 years). Male and female patients were affected equally. Headache was the most frequent symptom (n = 86, 80%). There were 6 patients (5 adults and 1 child) who reported positional headaches. The mean duration of signs and symptoms was shorter in adults versus pediatric patients (2.1 days vs. 6.5 days, P = 0.02), and more adults presented with signs and symptoms for less than 24 hours than did pediatric patients (38% vs. 6%, P = 0.01). Colloid cyst mean diameter was 2.0 cm (standard deviation 1.1, range 0.5-7.9 cm) and 96% measured 1 cm or larger. CONCLUSIONS: Our data suggests that the prodrome preceding sudden death in the setting of a colloid cyst may be shorter in adults. Also, most fatal colloid cysts measured 1 cm or larger.

[Ti] Title:Prostaglandin E : A Pancreatic Fluid Biomarker of Intraductal Papillary Mucinous Neoplasm Dysplasia.
[So] Source:J Am Coll Surg;225(4):481-487, 2017 Oct.
[Is] ISSN:1879-1190

[La] Language:eng
[Ab] Abstract:BACKGROUND: With the increased frequency of diagnostic imaging, pancreatic cysts are now detected in >3% of American adults. Most of these are intraductal papillary mucinous neoplasms (IPMNs) with well-established but variable malignant potential. A biomarker that predicts malignant potential or dysplastic grade would help determine which IPMNs require removal and which can be observed safely. We previously reported that pancreatic fluid prostaglandin E (PGE ) levels might have promise as a predictor of IPMN dysplasia and we seek to validate those results in the current study. STUDY DESIGN: Pancreatic cyst/duct fluid was prospectively collected from 100 patients with IPMN undergoing pancreatic resection. Surgical pathology revealed 47 low-/moderate-grade, 34 high-grade, and 20 invasive IPMNs. The PGE levels were assessed by ELISA and correlated with IPMN dysplasia grade, demographics, clinical radiologic/pathologic variables, acute/chronic pancreatitis, and NSAID use. RESULTS: Mean pancreatic cyst fluid PGE levels in high-grade and invasive IPMNs were significantly higher than low-/moderate-grade IPMNs (3.5 and 4.4 pg/µL, respectively, vs 1.2 pg/µL; p < 0.0016). At a threshold of 1.1 pg/µL, PGE was 63% sensitive, 79% specific, and 71% accurate for detection of high-grade/invasive IPMNs. When tested in the subset of IPMN patients with preoperative pancreatic cyst fluid CEA >192 ng/mL, PGE at a threshold of 0.5 pg/µL demonstrated 78% sensitivity, 100% specificity, and 86% accuracy for detection of high-grade/invasive IPMN. CONCLUSIONS: Our results validate pancreatic cyst fluid PGE as an indicator of IPMN dysplasia, especially in select patients with preoperative pancreatic cyst fluid CEA >192 ng/mL. The inclusion of PGE /CEA in a diagnostic biomarker panel can facilitate more optimal treatment stratification of IPMN patients.
