8081 Case report of sympathetic paraganglioma presenting as chronic catecholamine induced cardiomyopathy

Abstract Disclosure: Z. Tan: None. A. Taiwo: None. Background: Sympathetic paragangliomas are rare neuroendocrine tumors (<1/100,000) arising from extra-adrenal autonomic paraganglia, generally in the thorax, abdomen, and pelvis. They secrete catecholamines predominantly norepinephrine, which can cause a rare complication of catecholamine-induced cardiomyopathy. Clinical Case: A 33-year-old male, with history of obesity and borderline hypertension not on medication, presented with dyspnea on exertion, worsening paroxysmal nocturia dyspnea of 1 month duration and sudden onset of severe right flank pain. Work up for his chronic shortness of breath revealed: Troponin negative. EKG showed sinus tachycardia. Echocardiogram revealed enlarged left ventricle, severely decreased LV systolic function of 25-30%. Given the absence of angina symptoms, negative troponin, and EKG findings, his new-onset cardiomyopathy was presumed to be non-ischemic. CT chest, abdomen and pelvis was performed for the new onset right flank pain, which revealed a 4.1 cm x 4.0 cm centrally necrotic aortocaval soft tissue mass. This raise a concern about malignancy. A CT-guided Fine-Needle Aspiration of the retroperitoneal mass suggested paraganglioma. Further investigation showed plasma normetanephrine at 5.56 nmol/L (Reference range: 0-0.89 nmol/L), 24 hour urine normetanephrine at 2411 ug/d (Reference range: 114-865 ug/d), and 24 hour urine norepinephrine at 179 ug/d (Reference range: 14-20 ug/d). Plasma metanephrines and plasma dopamine were within the normal range. A gallium DOTATE PET/CT revealed a necrotic aortocaval mass with peripheral uptake, consistent with the known paraganglioma. He was diagnosed with sympathetic paraganglioma complicated with chronic catecholamine-induced cardiomyopathy and had exploratory laparotomy excision of his paraganglioma. Preoperatively, he was treated with phenoxybenzamine and carvedilol. However, his post-surgical course was complicated by acute on chronic heart failure and pneumonia, and he subsequently passed away from a pulseless electrical activity arrest. Conclusion: Although sympathetic paragangliomas rarely presents as catecholamine-induced cardiomyopathy, this case emphasizes the importance of considering hormonal abnormalities in patients who present with non-ischemic cardiomyopathy without high risk factors.

Phacoemulsification with Either Endocyclophotocoagulation or Ab-Interno Canaloplasty with or without Trabeculotomy in Uveitic Glaucoma

ABSTRACT Purpose Understanding the current role and efficacy of endocyclophotocoagulation (ECP) compared to ab-interno canaloplasty with or without trabeculotomy (OMNI), combined with cataract extraction and lens implantation (CEIOL), for the management of uveitic glaucoma (UG) is limited. Methods All UG patients ≥18 years old with ≥6 months of follow-up data (15.2 ± 5.9 months) after CEIOL combined with either ECP or OMNI from August 2019 to May 2022 at a single academic center were retrospectively reviewed [22 eyes of 15 patients (8 ECP, 14 OMNI)]. Surgical success was considered intraocular pressure (IOP) ≤21 mmHg and a reduction of baseline by ≥20% for two consecutive final visits without hypotony, additional surgery, or loss of light perception. Uveitic control was considered a <2-step increase in anterior chamber (AC) cell grade, <3+ AC cell grade, and no increase in steroid drop use at 3 months postoperatively. Secondary outcome measurements included postoperative change in IOP, glaucoma medications, best corrected visual acuity (VA), AC cell grade, and steroid drop frequency. Results Baseline ocular and preoperative characteristics of eyes (age, sex, laterality, uveitic location, systemic immunomodulating therapy, visual acuity, IOP, number of glaucoma medications, AC cell grade, and steroid drop frequency) did not significantly differ except for greater racial diversity in the ECP group. 62.5% eyes were surgically successful in the ECP group and 85.71% in the OMNI. Between-group analysis showed greater IOP reduction in the OMNI group (p < .05), but no difference in reduction of glaucoma medications (p = .33). No eyes displayed a two-step increase in or >3+ AC cell grade, however, 50% and 64.29%, respectively, increased steroid drop use. Between groups, no difference in the change of AC cell grade (p = .98) or steroid drop use (p = .84) was seen. Conclusions Both interventions improved visual acuity, IOP, and glaucoma medication use, however, OMNI was more successful at reducing IOP long term. An increase in steroid drop frequency may be the cost of a prolonged post-surgical inflammatory course related to underlying uveitis regardless of surgical approach.

Exploring the relationship between problematic eating behaviors and bipolar disorder: A study on candidates for bariatric surgery

BackgroundObesity is a major concern in patients with bipolar disorder (BD) and problematic eating behaviors have been suggested to mediate their relationship. The association between problematic eating behaviors and obesity has been studied but limited data have explored the role of BD. We investigated problematic eating behaviors among patients with BD compared with candidates for bariatric surgery (BS), with or without BD, and explored the possible correlations between mood spectrum, impulsivity, body mass index (BMI). Methods50 euthymic patients with BD and 200 subjects eligible for BS, 48 with BD (BS + BD) and 152 without BD (BS-BD), were recruited at the Psychiatric Clinic of University of Pisa. Assessments included: Structured Clinical Interview (SCID-5), Emotional Eating Scale (EES), Yale Food Addiction Scale (YFAS), Eating Disorder Inventory (EDI-2), Eating Disorder Questionnaire (EDE-Q), Night Eating Scale (NES), Grazing Questionnaire (GQ), Mood Spectrum Self-Report (MOOD-SR), Barratt Impulsivity Scale (BIS). ResultsBS + BD reported significantly higher EDI-2 and EDE-Q scores than the other groups. BD and BS + BD showed significantly higher BIS-11 scores than BS-BD. Among BS, EES and YFAS were associated with mood spectrum symptoms. LimitationsSmall BD sample size, BS may have underreported psychiatric symptoms to get approved for surgery, the interview didn't inquire about BS receiving GLP-1 agonists therapy. ConclusionsResults showed a high prevalence of problematic eating behaviors among patients with BD and severely obese. Problematic eating behaviors may aggravate BD symptoms. Mood spectrum symptoms in obese subjects need to be carefully researched in as relate to severity and post-surgical course of BS.

Surgical decompression in spinal Paget's disease: illustrative case.

Paget's disease of bone (PDB) is a common bone metabolic pathology in older adults, characterized by mixed osteolytic, osteoblastic, and quiescent periods. Surgical guidelines for PDB involving the spine are not well-defined and are reserved for cases refractory to medical treatments, typically bisphosphonates like zoledronic acid. This case study describes a 52-year-old male with PDB who presented with rapidly progressing myelopathy symptoms refractory to standard medical treatment, warranting surgical decompression. Surgical decompression and fusion, involving laminectomy with partial facetectomies, placement of pedicle screw instrumentation, and posterolateral arthrodesis spanning beyond the pathological segment, was performed. Follow-up visits indicated progressive improvement in symptoms and mobility, and imaging showed stable postsurgical changes with increased sclerosis in the affected vertebrae on a 2-year postsurgical course. This case underscores that PDB of the spine can transition from asymptomatic to significant impairment and demonstrates that surgical intervention can provide effective symptomatic relief in myelopathy secondary to PDB. The case contributes to the growing evidence of the effectiveness of surgical decompression in PDB involving the spine. https://thejns.org/doi/10.3171/CASE24203.

Aberrant left coronary artery from the pulmonary artery with patent ductus arteriosus - a case report and review of the literature

BackgroundAberrant left coronary artery from pulmonary artery (ALCAPA) is a very rare congenital heart defect. Its coexistence with patent ductus arteriosus (PDA) is extremely rare. The high pressures created by the left-to-right shunt in the pulmonary arteries can delay symptoms and create a real challenge in diagnosing ALCAPA. Missing this diagnosis can have severe results, including extensive ischemia and sudden death.Case presentationWe present a case of an infant born with a large PDA. Initially treated conservatively, however, due to congestive heart failure and lack of weight gain, she underwent surgical ligation of the PDA at the age of four and a half months. Following surgery, she developed pulmonary edema. Echocardiography revealed decreased ventricular function. ECG revealed ST elevations on lateral leads, and serum troponin was significantly increased. The patient underwent cardiac magnetic resonance imaging (MRI), which revealed signs of wall ischemia and decreased function of the left ventricle (LV) with unclear coronary anatomy. Diagnostic catheterization revealed an ALCAPA. She underwent surgical intervention, and the left coronary artery was re-implanted in the aortic sinus. Follow-up revealed slow improvement of cardiac function.Discussion and literature reviewThe coexistence of PDA and ALCAPA is a very rare occurrence. We found at least 10 reported cases in the literature. Delayed diagnosis might be detrimental. The prognosis of these patients is variable.ConclusionAn unusual post-surgical course following PDA repair requires a high index of suspicion and appropriate evaluation for ALCAPA, preferably with angiography.

Pain during the first year after scoliosis surgery in adolescents, an exploratory, prospective cohort study.

Approximately 50% of adolescents who have undergone scoliosis surgery still experience severe pain one year postoperatively. We explored the postoperative pain trajectory and the potential value of preoperative Thermal Quantitative Sensory Testing (T-QST) as predictor of chronic postsurgical pain after scoliosis surgery. Single-center prospective cohort study in adolescents undergoing scoliosis surgery. Prevalence of chronic postsurgical pain (CPSP) one year after scoliosis surgery and postsurgical pain course during this year. The need for rescue medication and the relationship between pre-operative T-QST, acute pain and CPSP. Thirty-nine patients (mean age 13.9 years; SD 1.9 years) completed the study. One year postoperatively, ten patients (26%) self-reported pain [numeric rating scale (NRS) score ≥ 4]) when moving and two (5%) when in rest. Four of these patients (10.3%) experienced neuropathic pain. The pre-operative cold pain threshold was lower (p = 0.002) in patients with CPSP at 12 months. Preoperative cold and heat pain thresholds were correlated with the number of moderate or severe pain reports (NRS ≥ 4) in the first week postoperatively (r -.426; p = 0.009 and r.392; p = 0.016, respectively). One year after scoliosis surgery, a significant part of patients (26%) still reported pain, some with neuropathic characteristics. Better diagnosis and treatment is needed; our study suggests that T-QST could be further explored to better understand and treat children with this negative outcome.

Eating disorders among bariatric surgery patients: The chicken or the egg?

Postoperative eating behaviors and unhealthy weight control measures are leading causes of bariatric surgery complications. Candidates for bariatric surgery and individuals with eating disorders may share common risk factors, such as a history of dieting, and/or being bullied or teased for their weight. Binge-eating disorder, night eating syndrome, and bulimia nervosa are the most common eating disorders among candidates for bariatric surgery before the operation. Malnutrition, stress, and intense fear of weight gain can lead to the development of an eating disorder after surgery as well. Plugging, grazing, loss of control eating, dumping, and food avoidance are specific disordered behaviors that may present after bariatric surgery. To improve physical and psychological outcomes for individuals under their care, clinicians can screen for these disordered behaviors and distinguish them from a healthy diet and the expected postsurgical course.

319. A SUCCESSFUL CASE OF VACUUM-STENT TREATMENT FOR ANASTOMOTIC LEAKAGE AFTER ESOPHAGECTOMY WITH COMPLICATED POST-SURGICAL COURSE

Abstract Background Anastomotic leakage after esophagectomy is associated with severe morbidity. Endoscopic vacuum therapy (EVT) has gained a greater role in endoscopic treatment of these defects and is most often applied using endoscopically placed vacuum-sponges. Recently, the vacuum-stent was introduced as a new device to apply EVT, combining the benefits of negative pressure wound therapy and an intraluminal stent, while allowing for oral intake of a soft diet. Methods This video describes a patient with anastomotic leakage after esophagectomy with complicated post-surgical course, successfully treated with a vacuum-stent, including the technical aspects of the technique. First, a guidewire was placed and the vacuum-stent was advanced over the guidewire and introduced into the esophagus. The vacuum-stent was placed over the defect and deployed using the distal release system. Lastly, the vacuum-stent was connected to a vacuum pump, which was set to a pressure of -125 mmHg on the day of placement and -75 mmHg from the second day on. Generally, the vacuum-stent was removed after 7 days. If the defect persisted, another vacuum-stent was placed. Case/Results: A 65-year-old female had undergone a minimally invasive esophagectomy with gastric conduit reconstruction and intrathoracic anastomosis. Post-surgically, the patient had dysphagia due to an elongated gastric conduit, only improving after stent placement. However, this caused a stent-induced broncho-esophageal fistula and was no definite treatment. Therefore, she underwent surgery to close the fistula with a bovine patch and gastric conduit re-construction. A prophylactic vacuum-sponge was placed, but 8 days post-surgery, endoscopy showed a dislocated sponge and dehiscence of the complete anastomosis. A vacuum-stent was placed. After 3 vacuum-stents in 20 days, the defect had closed endoscopically, which was confirmed by CT-scan with oral contrast. Conclusions The vacuum-stent seems to be a safe and possibly organ-saving treatment option for anastomotic leakage after esophagectomy. Link to video: https://we.tl/t-eOVEhUiwge

Implication of nutritional status for adverse outcomes after surgery for metastatic spine tumors.

Surgery for metastatic spinal tumors can have a substantial impact on patients' quality of life by alleviating pain, improving function, and correcting spinal instability when indicated. The decision to operate is difficult because many patients with cancer are frail. Studies have highlighted the importance of preoperative nutritional status assessments; however, little is known about which aspects of nutrition accurately inform clinical outcomes. This study investigates the interaction and prognostic importance of various nutritional and frailty measures in patients with spinal metastases. A retrospective analysis of consecutive patients who underwent surgery for spinal metastases between 2014 and 2020 at the Massachusetts General Hospital was performed. Patients were stratified according to the New England Spinal Metastasis Score (NESMS). Frailty was assessed using the metastatic spinal tumor frailty index. Nutrition was assessed using the prognostic nutritional index (PNI), preoperative body mass index, albumin, albumin-to-globulin ratio, and platelet-to-lymphocyte ratio. Outcomes included postoperative survival and complication rates, with focus on wound-related complications. This study included 154 individuals (39% female; mean [SD] age 63.23 [13.14] years). NESMS 0 and NESMS 3 demonstrated the highest proportions of severely frail patients (56.2%) and nonfrail patients (16.1%), respectively. Patients with normal nutritional status (albumin-to-globulin ratio and PNI) had a better prognosis than those with poor nutritional status when stratified by NESMS. Multivariable regression adjusted for NESMS and frailty showed that a PNI > 40.4 was significantly associated with decreased odds of 90-day complications (OR 0.93, 95% CI 0.85-0.98). After accounting for age, sex, primary tumor pathology, physical function, nutritional status, and frailty, a preoperative nutrition consultation was associated with a decrease in postoperative wound-related complications (average marginal effect -5.00%; 95% CI -1.50% to -8.9%). The PNI was most predictive of complications and may be a key biomarker for risk stratification in the 90 days following surgery. Nutrition consultation was associated with a reduced risk of wound-related complications, attesting to the importance of this preoperative intervention. These findings suggest that nutrition plays an important role in the postsurgical course and should be considered when developing a treatment plan for spinal metastases.

Rates of surgical site infections and length of stay following major gynecologic oncology surgery for patients on federally funded insurance: A 6-month retrospective cohort.

e18627 Background: An estimated 94,000 women have newly diagnosed gynecologic cancer annually–with rates increasing over the last 20 years. The incidence of gynecologic cancers is known to vary by insurance status; more specifically, uninsured or federally insured women are more likely to have advanced-stage disease at the time of diagnosis and worse overall survival compared to privately insured women. Surgical site infections (SSIs) complicate up to 4% of hysterectomies in the United States. Other post-operative sequelae, such as wound dehiscence and 30-day readmission, further complicate the post-surgical course. We sought to determine differences in postoperative outcomes for patients with private and federally-funded insurance plans, such as SSI, length of hospital stay, and 30-day wound dehiscence, and 30 all-cause readmission following gynecologic oncologic surgery. Methods: We conducted a retrospective cohort study from a large metropolitan academic health system between January 1st, 2022, to June 30th, 2022. The study population included adult women who received gynecologic oncologic surgery–surgical staging or interval cytoreduction. Postoperative complications were compared to national rates from the National Surgical Quality Improvement Project (NSQIP) database. Trends were analyzed using chi-squared analysis and a two-sample t-test. Results: Over our 6-month study period, 233 patients underwent gynecologic oncologic surgery. Robotic-assisted hysterectomies were the most common (27.89%, n = 65), followed by total abdominal hysterectomies (21%, n = 49), laparoscopic hysterectomies (7.72%, n = 18), and supracervical hysterectomies (3%, n = 7). More patients required bilateral salpingo-oophorectomy (63.51%, n = 148) compared to unilateral procedures (9.87%, n = 23). Although most patients had private insurance (73.39%, n = 171), 26.1% had federally-funded health plans (n = 62)–Medicaid and Medicare. Rates of wound dehiscence were higher than the NSQIP rate of 1% among our cohort (3%, n = 7). Although there was a high rate of 30-day readmission (9.44%, n = 22) compared to NSQIP rate of 6.1%, the incidence of SSI was fewer than the NSQIP rate of 4% (3.86%, n = 9). Upon intersectional analysis, patients with federal insurance plans had higher rates of SSI (n = 5, p &lt; 0.05). Specifically, Medicare patients had a longer average length of stay at 2.64 days (p &lt; 0.05) compared to a study average of 1.76 days. Conclusions: Patients with federal insurance had longer hospital stays and higher rates of SSI compared to those with private plans. There was no difference in 30-day wound dehiscence or 30-day all-cause readmission between study populations. More studies are needed to risk-stratify patients by insurance type before gynecologic oncology surgery to improve postoperative outcomes further.

NO BUGS: Nosocomial operative best-practices for unplanned infections in gynecologic surgery: A 6-month retrospective.

e18765 Background: An estimated 94,000 women have newly diagnosed gynecologic cancer (ovarian, uterine, cervical, and vulvovaginal) annually–with rates increasing over the last 20 years. Surgical site infections (SSIs) complicate up to 4% of all hysterectomies in the United States. Other surgical sequelae, such as operative length, estimated blood loss, wound dehiscence, and 30-day readmission, further complicate the post-surgical course of this vulnerable population. Methods: A quality improvement initiative was conducted in a large academic health system between January to June 2022 to investigate whether implementing an SSI bundle, defined as a set of 11 evidence-based practices performed collaboratively, can reduce intraoperative and postoperative complications. The study population included women who received gynecologic oncologic surgery. To evaluate trends following the implementation of an SSI prevention bundle, we studied two time periods: 1/1/22-3/31/22 and 4/1/22-6/30/22. Trends were analyzed using chi-squared and a two-sample t-test. Results: Over our six-month study period, 233 patients underwent primary gynecologic oncologic surgery. Robotic-assisted hysterectomies were the most common (27.89%, n = 65), followed by total abdominal hysterectomies (21%, n = 49), laparoscopic hysterectomies (7.72%, n = 18), and supracervical hysterectomies (3%, n = 7). An invasive, abdominal approach was needed for less than half of the surgeries for whom intraoperative and postoperative outcomes were measured (46.35%, n = 108). Following the implementation of our SSI bundle, there was a rise in estimated blood loss (134.49 to 252.67 mL), operative length (199.24 to 227.23 min), and length of stay (1.58 to 2.20 days). Yet, there was a decline in the SSI rate from 4.62% to 3.7% (p = 0.97) and 30-day all-cause readmission from 12.96% to 7.4% (p &lt; 0.05). The overall incidence of 30-day wound dehiscence also declined over six months from 3.7% to 1.85% (p = 0.74). Upon intersectional analysis, patients with SSI were older (55.93 vs. 62, p = 0.39) and were more likely to be obese (BMI 27.04 vs. 31.06, p &lt; 0.05). Individuals with functional status limitations, ECOG score &gt; 2, had longer lengths of stays (4.7 vs. 1.76 days, p &lt; 0.05), estimated blood loss (230 vs. 185.9 mL, p = 0.12), and operative length (374 vs. 205.2 min, p &lt; 0.001). Those with a supracervical hysterectomy also had a longer length of stays (4 days, p &lt; 0.05), blood loss (921.43 mL, p &lt; 0.001), and operative lengths (315.14 min, p &lt; 0.001). Conclusions: Following the implementation of an evidence-based SSI quality improvement project, cancer patients had fewer SSI, hospital readmissions, and wound dehiscence. High ECOG scores, supracervical hysterectomies, and obesity were all associated with worse postoperative outcomes. Prospective studies on postoperative surgical quality are needed to improve care for our most vulnerable patients.

Neurofibromatosis type 1-associated plexiform neurofibromas of the neck: topography of lesions and surgical treatment data of 69 patients

PurposePlexiform neurofibromas (PNF) are rare tumors arising from peripheral nerve sheath cells. PNF are a hallmark in patients with neurofibromatosis type 1 (NF1), a tumor predisposition syndrome. PNF often grow invasively and destructively, what may complicate surgical treatment. Data on frequency, location, and surgical procedures of patients with NF1-associated FPNF are scarce. This study provides treatment data of NF1 patients.MethodsLocalization and treatment data of 69 NF1 patients with neck PNF were analyzed. Frequency of lesions was recorded in coded colors on schematic neck drawings.ResultsThe tumors showed no side preference, were located in the entire area under investigation, and did not respect anatomical units/dermatomes. However, the sternocleidomastoid region was particularly frequently affected. The mean number of surgical measures per patient was 1.33. Complications were extensive swelling, hematoma, and bleeding. Histological assessment usually confirmed the clinical assessment of neoplasm. However, histologic differentiation of PNST reveals differences in between tumors that have been unified in clinical assessment as PNF.ConclusionThe color-coded, schematic overview of the frequency distribution of surgical neck interventions in NF1 patients with PNF proved a useful tool to gain assessment of preferred treatment needs. The imaging procedure may be suitable for controlling the external aspect of natural tumor development (growth, effects of aging) in the same way as the documentation of the post-surgical course. Treatment plans for patients with these tumors should consider that repeated interventions may be necessary to achieve a longer-term stable result.

The safety of respiratory positive pressure support immediately following pediatric tonsillectomy.

Adenotonsillectomy is the first-line treatment for pediatric obstructive sleep apnea (OSA). The postoperative course may be complicated by hypoxia, requiring intervention. Positive pressure respiratory support (PPS) could be used to bridge the postoperative period and avoid invasive mechanical ventilation; however, the safety of PPS following tonsillectomy has not been established. Objective To review the incidence of complications and risk factors associated with PPS use immediately after tonsillectomy. A retrospective cohort study between 2015 and 2020 of patients who underwent tonsillectomy and were admitted to the pediatric intensive care unit at a single healthcare system. Seven hundred eighty patients met inclusion criteria, including 101 patients treated with PPS immediately following surgery. A similar number of patients were diagnosed with severe OSA in each group prior to surgery. One patient in the PPS cohort developed pneumomediastinum and pneumothorax. Eleven patients (12%) in the PPS group and 18 patients (2%) in the non-PPS group developed life-threatening complications, defined as pneumothorax/pneumomediastinum, re-intubation, post-tonsillectomy bleeding that required surgical intervention, pulmonary edema and death, and all occurred in patients who had not used PPS at baseline. Regression analysis identified body mass index, surgical technique, and PPS use to be associated with increased odds of life-threatening complications. Our study suggests that PPS is generally safe to use. New-onset PPS is associated with increased odds of life-threatening complications, likely reflecting a severe post-surgical clinical course.

Laryngeal Primary Myoepithelial Carcinoma: Case Report and a Systematic Review of Literature.

Myoepithelial carcinoma of the head and neck is a rare malignant tumor that usually arises from the salivary glands but rarely from the larynx. Here, we describe 11 cases (one treated by us and 10 previously published) of laryngeal myoepithelial carcinoma. Our patient was a 60-year-old male who initially presented with hoarseness and throat pain. The patient had suffered from continuing hoarseness and throat pain for one month before he consulted an otorhinolaryngologist. Computed tomography (CT) scan showed a polypoid tumor involving the right vocal cords. Biopsy was performed, and the disease was pathologically diagnosed as myoepithelial carcinoma of the larynx by hematoxylin-eosin and immunohistochemical staining. The total follow-up period was 15months. Repeated laryngoscopies or CT scans revealed no recurrence or residual lesion during the post-surgical course.

Neurofibromatosis Type 1-Associated Plexiform Neurofibromas of the Face and Adjacent Head Regions: Topography of Lesions and Surgical Treatment Data of 179 Patients

IntroductionFacial plexiform neurofibromas (FPNF) are rare tumors frequently diagnosed in patients with neurofibromatosis type 1 (NF1), a tumor predisposition syndrome. FPNF often grows invasively and destructively, which may complicate surgical treatment. Data on the frequency, location, and surgical procedures of patients with NF1-associated FPNF are scarce. This study provides treatment data from a nationally networked reference center for the treatment of NF1 patients.Material and MethodsThe localization and treatment data of 179 NF1 patients with FPNF were analyzed. Photographically documented tumors of the study area, further determined by imaging, were manually transferred to a facial scheme and digitized. The digitized registrations of the facial extensions of the tumors of each patient were overlaid in a single image (Photoshop™), so that the file of the facial scheme contained the sum of the tumor localization. Finally, the frequency of tumor localization was indicated with a color code. The frequency of tumor extension-related coded colors was applied to outline the lesions' topography on schematic face drawings (heat map).ResultsThe distribution of the tumors showed no side preference. The need for the treatment of patients with orbital/periorbital manifestations became evident in the graphic representations. Tumors do not respect anatomical units. However, the classification of the face according to dermatomes, especially the trigeminal nerve, offers indications of tumor spread and guides treatment planning. The mean number of surgical measures per patient was 2.21 (median: 1). Extensive swelling, hematoma, and delayed wound healing were all common postoperative complications.ConclusionThe color-coded, schematic overview of the frequency distribution of cutaneous tumor spread in NF1 patients with FPNF illustrates the importance of orbital/periorbital and cheek tumor manifestations in patients' treatment needs. The imaging procedure is suitable for controlling natural tumor growth in the same way as the documentation of the post-surgical course. Repeated interventions in the region are included in surgical planning of the progressing tumor disease.

Temporal sylvian fissure arachnoid cyst in children: treatment outcome following microsurgical cyst fenestration with special emphasis on cyst reduction and subdural collection

ObjectivesControversy remains regarding surgical managements of sylvian fissure arachnoid cyst (SFAC). This review presents our experience in the microsurgical fenestration of pediatric patients with SFAC to define surgical indication, and risks and benefits with special emphasis on postoperative subdural fluid collection (SDFC) and cyst size reduction.MethodsThirty-four children with SFAC who underwent microsurgical cyst fenestration at a single institution over a 10-year period were retrospectively reviewed for their clinical presentation, neuroimaging findings, and postsurgical course. The SFACs were classified by a novel grading system based on the degree of arachnoid cyst extension from the sylvian fissure to the insular cistern shown on MR images: grade 0 — little or no prominence of sylvian fissure, grade I — SFAC confined to the sylvian fissure, grade II — SFAC partially extending to the insular cistern, grade III — SFAC extending to the entire insular cistern.ResultsThere were 26 males and 8 females. SFAC was present in the left side in 24. Twelve patients presented with cyst rupturing to the subdural space. Cyst grading did not show significant difference compared with rupture status (p > 0.9). All patients underwent microsurgical cyst fenestration. Postoperative SDFC is common but often resolved overtime in two-thirds of the cases with the mean average of 6 months. However, 3 patients had symptomatic postoperative SDFC and needed reoperation shortly after the first operation. Microsurgical cyst fenestrations for SFAC effectively resolved the presenting symptoms and often showed restorations of intracranial structures on follow-up imaging. Cyst resolution or reduction greater than 75% was noted in 61.8% of the patients postoperatively which was noted in a half of the SFAC of children even with age of 11 years or older. During the follow-up, no cyst recurrence or SDFC was noted. Patients with greater surgical reduction of cyst size tended to occur in younger children, and those with lower MR grade.ConclusionOur results showed a high reduction rate of SFAC and brain re-expansion after microsurgical fenestration together with symptomatic improvements regardless the patient’s age. Considering the developing CNS during childhood, reductions of a large space-occupying lesion followed by restorations of the structural integrity of the developing brain are very desirable. However, a multi-center cooperative prospective longitudinal study on long-term comparative data of those treated and untreated of neuro-psychological outcome and cyst rupture incidence is needed.

Laparoscopic Hemi-Hysterectomy for Excision of a Functional Rudimentary Uterine Horn Keys to Success

<h3>Study Objective</h3> To present a case of unicornuate uterus with a non-communicating rudimentary horn complicated with hematometra and describe important steps for successful laparoscopic surgical management. <h3>Design</h3> Description of the relevant anatomy and surgical technique with the use of video. <h3>Setting</h3> academic tertiary hospital. <h3>Patients or Participants</h3> A 19-yo female patient with history of dysmenorrhea. Exam revealed normal vagina and cervix deviated to the left, with an adnexal mass on the right. Ultrasound and MRI further delineated a right rudimentary horn with active endometrium, possible hematometra. A renal ultrasound ruled out renal anomaly. Hysteroscopy revealed a normal appearing unicornuate uterus with a tubal ostium. A Rummi manipulatorwas placed. Then, laparoscopic pelvic survey confirmed a left unicornuate uterus with an enlarged right rudimentary horn, no endometriosis was found. Next, ureterolysis was performed, followed by right salpingectomy with ovarian preservation. Vasopressin was injected to the base of the horn (20 units in 100 ml of normal saline). The right utero-ovarian and round ligament were taken down with ligasure device and bladder flap was developed. Next, monopolar L hook was used to resect the rudimentary horn. This was followed by uterine closure in two layers with 2-0 V lock barbed suture. Rudimentary horn was exteriorized in a 10 cm endobag. <h3>Interventions</h3> surgical procedure: diagnostic hysteroscopy, laparoscopic hemihysterectomy for excision of a functional non communicating rudimentary horn. <h3>Measurements and Main Results</h3> Patient was discharged on the same day of the procedure and had an uncomplicated postsurgical course. <h3>Conclusion</h3> Understanding the nature of the uterine anomaly before surgery is of paramount importance for the management of obstructive anomalies of the female genital tract. Laparoscopy is a safe and effective treatment modality to provide pain relief, avoid sequelae, and allow for the preservation of reproductive function.

Symptom Burden in Glioblastoma: A Prospective Pilot Study from Diagnosis to First Progression

Introduction: The evaluation of symptom burden, performance status, and neurological function is still challenging in glioblastoma (GBM) patients. Patients may suffer from a wide spectrum of neurological symptoms like cognitive deficits, aphasia, or hemiparesis, which interfere to report to comprehensive questionnaires. However, an integrated and reliable neuro-oncological assessment is the key in the clinical management and in the evaluation of treatment benefits for GBM patients. Methods: We implemented an easy-to-use clinical toolkit for the prospective assessment and follow-up evaluation of GBM patients using the Karnofsky performance status (KPS), the National Institute of Health Stroke Scale (NIH-SS), and simple scores for the evaluation of key symptoms like fatigue, depression, and headache. Results: We prospectively followed 50 patients. The composite score (headache, depression, and fatigue), fatigue alone, the NIHSS, and the KPS were suitable biomarkers to evaluate symptom burden in GBM patients and indicate clinical disease progression. Discussion/Conclusion: The proposed clinical toolkit seems feasible in routine clinical practice and reflects changes in symptom burden in different stages of the postsurgical course of GBM patients in this monocentric clinical pilot trial.

Crohn’s Disease-Related Stoma Complications and Their Impact on Postsurgical Course

Introduction: Crohn’s disease (CD) is a chronic inflammatory disease of the gastrointestinal tract. The diversion through a colostomy or an ileostomy is sometimes required for disease control. In these patients, common stoma-related complications sum up with CD-related complications and often require revisional surgery. Methods: The aim of the study was to assess stoma morbidity after surgery for CD and to identify the burden of CD-related or CD-associated complications. Thus, details of past medical history, surgery, and follow-up of 54 consecutive patients operated on for CD with any sort of stoma were retrieved from the stoma therapist prospectively maintained database. Results: In our series, 23 patients had a colostomy, and 31 patients had an ileostomy. Complications occurred after stoma creation in 38 patients (70%) at a median of 1.3 months (interquartile range 0.6–7.2). CD-related complications arose in 8 patients (including pyoderma gangrenosum in 3 patients, peristomal fistulae in 2, granulomas in 2, and peristomal abscess in 1). Patients with CD-related complications tended to have a shorter disease duration (p = 0.07) and higher occurrence of CD-related complications was associated with end-stoma (p = 0.006). In this cohort, 11 cases had to be surgically treated for peristomal fistulae or abscess, parastomal hernia, prolapse, pyoderma gangrenosum, and recurrent CD. Discussion/Conclusions: In patients with CD, stoma creation is burdened by a high rate of postoperative complication and a relevant rate is specifically related to CD. Often these patients are required to be reoperated on to redo the stoma. Moreover, end-stoma configuration and aggressive CD phenotype are associated to a higher rate of complications.

Pancreatic intraepithelial neoplasia with carcinoma in situ with repeated distally localized pancreatitis: a case report

BackgroundAcute pancreatitis could be an early symptom of pancreatic cancer. However, repeated pancreatitis caused by pancreatic cancer is very rare.Case presentationA 69-year-old man was referred to our hospital with severe abdominal pain, and serial imaging studies showed acute distally localized pancreatitis with a pseudocyst. Although he had successful conservative medical treatment followed by discharge from the hospital, he was re-admitted with severe abdominal pain for recurrent distal pancreatitis with splenic artery aneurysm followed by its rupture. No pancreas mass was detected by imaging studies including endoscopic ultrasound and cytologic studies of the pancreas juice did not show any malignant cells, although slight dilatation of distal pancreas duct was observed only in the initial computed tomography. Because of the episodes of repeated distally localized pancreatitis caused by possible pancreatic ductal neoplasm, we planned and performed laparoscopy-assisted distal pancreatectomy after full-informed consent. Pathological examination revealed pancreatic intraepithelial neoplasia (PanIN) with carcinoma in situ in the distal main pancreas duct. The post-surgical course of the patient was uneventful and he was discharged 10 days after surgery from recurrent disease for over a year.ConclusionsWe encountered a case of repeated episodes of acute distally localized pancreatitis, for which distal pancreatectomy was performed, resulting in pathological diagnosis of PanIN with carcinoma in situ.
