Satisfactory Outcome

Adult intussusception during the perioperative period is defined as an extremely rare condition, especially when it emerges within short intervals of laparotomy, which may be explained as an unphysiological peristaltic function of the bowel without any lead points. Accurate diagnosis and therapeutic schedule predict a satisfactory outcome. Here, we introduce the case of a 32-year-old man who had symptoms of abdominal pain, no gas emission, and defecation shortly after liver transplantation. Intussusception was definitely diagnosed by abdominal CT, and then reduction was operated successfully by three-dimensional laparoscopy-assisted operation. There were no other complaints, and no secondary lesions were detected during the postoperative rehabilitation process in the hospital and over a follow-up period of 6 months. Relevant literature has been summarized subsequently. A promising minimally invasive surgery along with minimal secondary trauma was presented by laparoscopy in this rare case, providing the potential remedy for perioperative intussusception in the adult.

Abstract Background Hypothermic machine perfusion (HMP) improves the quality of donor livers for transplantation, both in animal models and in clinical practice. Treatment with SP600125, an inhibitor of c-Jun N-terminal kinase (JNK), can suppress the JNK signaling pathway to alleviate donor liver ischemia–reperfusion injury (IRI). We performed the present study with the objective of exploring the protective effects exerted by a combination of HMP and SP600125 on liver xenograft viability for donation after cardiac death (DCD) in a porcine model. Methods 54 adult BAMA mini-pigs were randomly assigned to 5 groups, including sham, cold storage for 4 h (CS 4 h), CS 4 h + SP600125, CS 2 h + HMP 2 h, and CS 2 h + HMP 2 h + SP600125 groups. Donor livers in the CS 4 h and CS 4 h + SP600125 groups were conventionally cold preserved for 4 h, whereas donor livers in the CS 2 h + HMP 2 h and CS 2 h + HMP 2 h + SP600125 groups were cold preserved for 2 h and then treated with HMP for 2 h. The preservation and perfusion solutions contained SP600125 (20 µM). Follow-up was conducted for 5 days after liver transplantation to compare the surgical outcomes by means of serological examination, pathological results, and survival rate. Results The most satisfactory outcome after liver transplantation was observed in the CS 2 h + HMP 2 h + SP600125 group, which presented with minimal damage of donor livers during 5 days’ follow-up. Additionally, serological examination, pathological results, and survival rate concurred in showing better results in the CS 2 h + HMP 2 h ± SP600125 group than in the CS 4 h ± SP600125 group. Conclusion HMP in combination with SP600125 has hepatoprotective properties and improves the quality and viability of porcine livers collected after DCD, thus improving prognosis after liver transplantation.

Background & Aims: Autoimmune pancreatitis (AIP) is a fibroinflammatory condition affecting the pancreas and could present as a multisystem disorder. Diagnosis and management can pose a diagnostic challenge in certain groups of patients. We report our experience of managing this condition in a tertiary pancreaticobiliary centre in the North East of England.Methods: Patients were identified from a prospectively maintained database of patients diagnosed with AIP between 2005 and 2013. Diagnosis of definite/probable AIP was based on the revised HISORt criteria. When indicated, patients were treated with steroids and relapses were treated with azathioprine. All patients have been followed up to date.Results: Twenty-two patients were diagnosed with AIP during this period. All patients had pancreatic protocol CT performed while some patients had either MR or EUS as part of the work up. Fourteen out of 22 (64%) had an elevated IgG4 level (mean: 10.9 g/L; range 3.4 - 31 g/L). Four (18%) patients underwent surgery. Extrapancreatic involvement was seen in 15 (68%) patients, with biliary involvement being the commonest. Nineteen (86%) were treated with steroids and five (23%) required further immunosuppression for treatment of relapses. The mean follow up period was 36.94 months (range 7 - 94).Conclusion: Autoimmune pancreatitis is being increasingly recognized in the British population. Extrapancreatic involvement, particularly extrahepatic biliary involvement seems to be a frequent feature.Diagnosis should be based on accepted criteria as this significantly reduces the chances of overlooking malignancy. Awareness of this relatively rare condition and a multi-disciplinary team approach will help us to diagnose and treat this condition more efiectively thereby reducing unnecessary interventions.

Microsurgical Resection

Foramen magnum (FM) meningiomas are challenging lesions. We present the case of a 38-year-old female with neck pain, dysphonia, and slight twelfth nerve palsy. Imaging workup was highly suggestive of an FM meningioma, and microsurgical resection with the aid of intraoperative neurophysiological monitoring was indicated. A transcondylar approach was employed, the vertebral artery was mobilized, and the tumor was completely removed. Postoperative MRI demonstrated complete resection. There were no signs of cervical instability. The patient presented with improvement of her symptoms and no new neurological deficit on follow-up. FM meningiomas can be successfully resected using a transcondylar approach, since it increases the exposure of the ventral FM, allowing the surgeon to work parallel to the skull base and flush with the tumor’s attachment. Informed consent was obtained from the patient for publication of this operative video.The video can be found here: https://youtu.be/itfUOB-6zM0.

RESUMOIntrodução: A Arterite de Takayasu (AT) consiste em uma vasculopatia de origem indefinida, sendo de caráter crônico, que afeta a aorta e seus ramos principais. Em gestantes é uma condição complexa, em que o tratamento clínico é realizado com restrições. A utilização de corticoides tem sido favorável no controle inflamatório, principalmente naqueles casos em que antes da gravidez se fazia uso de imunossupressores. Casuística: Foi relatado um caso de uma gestante portadora de AT, através da análise de prontuário e de exames complementares, sendo realizado o pré-natal pelas equipes de Obstetrícia e Reumatologia, onde foi realizado tratamento clínico com corticoides, mostrando uma evolução satisfatória, ocorrendo apenas uma hospitalização que foi seguida de uma cesárea na trigésima sexta semana de gravidez, com recém nato saudável de 3.810g. Discussão: A AT pode estar associada a várias etiologias, sendo a gênese pouco conhecida. O diagnóstico na maioria das vezes é demorado, pela dificuldade da suspeita clínica, além de demandar o uso de técnicas de imagem mais sofisticadas. A gestação associada é fenômeno raro, já que as portadoras são orientadas a evitarem a gravidez. O controle clínico permitiu uma gestação sem grandes complicações e serviu como meio para levar a gestação até praticamente o fim do terceiro trimestre. Conclusão: Deve-se ressaltar o papel do acompanhamento clínico, especialmente com esta pan-arterite, mostrando os medicamentos que podem ser utilizados nesse grupo, especialmente quando se usava imunossupressores antes da gravidez. Palavras chave: Arterite de Takayasu, Gravidez, Vasculite. ABSTRACT:Introduction: Takayasu's arteritis (TA) consists of a vascular disease of unknown origin and chronic nature, which affects the aorta and its main branches. In pregnant women it is a complex condition, in which the clinical treatment is performed with restrictions. The use of corticosteroids has been favorable to control inflammation, especially in those cases when immunosuppressant had been used before pregnancy. Case Report: A case of a pregnant patient with TA has been reported through the analysis of medical records and laboratory tests. The Obstetrics and Rheumatology staff performed the prenatal care, and clinical treatment with corticosteroids was done showing a satisfactory outcome. There was only one hospitalization of the patient, which was followed by a cesarean in the thirty sixth week of pregnancy.  The newborn was a healthy one, weighing 3.810g. Discussion: TA may be associated with several etiologies, and the genesis is little known. The diagnosis most often takes time due to the difficulty of clinical suspicion, and requires the use of more sophisticated imaging techniques. The pregnancy is rare phenomenon, since the carriers are advised to avoid pregnancy. The clinical management allowed a pregnancy without major complications and served as a means to carry the pregnancy to almost the end of the third quarter. Conclusion: The role of the clinical follow-up should be noticed especially with this pan-arteritis, showing the drugs that can be used in this group, especially when there is use of immunosuppressive drugs before pregnancy. Keywords: Takayasu Arteritis, Pregnancy, Vasculitis.

Abstract OBJECTIVE: Despite the success of stereotactic radiosurgery, large inoperable arteriovenous malformations (AVMs) of 14 cm3 or more have remained largely refractory to stereotactic radiosurgery, with much lower obliteration rates. We review treatment of large AVMs either previously untreated or partially obliterated by embolization with fractionated stereotactic radiotherapy (FSR) regimens using a dedicated linear accelerator (LINAC). METHODS: Before treatment, all patients were discussed at a multidisciplinary radiosurgery board and found to be suitable for FSR. All patients were evaluated for pre-embolization. Those who had feeding pedicles amenable to glue embolization were treated. LINAC technique involved acquisition of a stereotactic angiogram in a relocatable frame that was also used for head localization during treatment. The FSR technique involved the use of six 7-Gy fractions delivered on alternate days over a 2-week period, and this was subsequently dropped to 5-Gy fractions after late complications in one of seven patients treated with 7-Gy fractions. Treatments were based exclusively on digitized biplanar stereotactic angiographic data. We used a Varian 600SR LINAC (Varian Medical Systems, Inc., Palo Alto, CA) and XKnife treatment planning software (Radionics, Inc., Burlington, MA). In most cases, one isocenter was used, and conformality was established by non-coplanar arc beam shaping and differential beam weighting. RESULTS: Thirty patients with large AVMs were treated between January 1995 and August 1998. Seven patients were treated with 42-Gy/7-Gy fractions, with one patient lost to follow-up and the remaining six with previous partial embolization. Twenty-three patients were treated with 30-Gy/5-Gy fractions, with two patients lost to follow-up and three who died as a result of unrelated causes. Of 18 evaluable patients, 8 had previous partial embolization. Mean AVM volumes at FSR treatment were 23.8 and 14.5 cm3, respectively, for the 42-Gy/7-Gy fraction and 30-Gy/5-Gy fraction groups. After embolization, 18 patients still had AVM niduses of 14 cm3 or more: 6 in the 7-Gy cohort and 12 in the 5-Gy cohort. For patients with at least 5-year follow-up, angiographically documented AVM obliteration rates were 83% for the 42-Gy/7-Gy fraction group, with a mean latency of 108 weeks (5 of 6 evaluable patients), and 22% for the 30-Gy/5-Gy fraction group, with an average latency of 191 weeks (4 of 18 evaluable patients) (P = 0.018). For AVMs that remained at 14 cm3 or more after embolization (5 of 6 patients), the obliteration rate remained 80% (4 of 5 patients) for the 7-Gy cohort and dropped to 9% for the 5-Gy cohort. A cumulative hazard plot revealed a 7.2-fold greater likelihood of obliteration with the 42-Gy/7-Gy fraction protocol (P = 0.0001), which increased to a 17-fold greater likelihood for postembolization AVMs of 14 cm3 or more (P = 0.003). CONCLUSION: FSR achieves obliteration for AVMs at a threshold dose, including large residual niduses after embolization. With significant treatment-related morbidities, further investigation warrants a need for better three-dimensional target definition with higher dose conformality.

Study Design: Retrospective multicenter. Objectives: diffuse idiopathic skeletal hyperostosis (DISH) involving the cervical spine is a rare condition determining disabling aero-digestive symptoms. We analyzed impact of preoperative settings and intraoperative techniques on outcome of patients undergoing surgery for DISH. Methods: Patients with DISH needing for anterior cervical osteophytectomy were collected. Swallow studies and endoscopy supported imaging in targeting bone decompression. Patients characteristics, clinico-radiological presentation, outcome and surgical strategies were recorded. Impact on clinical outcome of duration and time to surgery and different surgical techniques was evaluated through ANOVA. Results: 24 patients underwent surgery. No correlation was noted between specific spinal levels affected by DISH and severity of pre-operative dysphagia. A trend toward a full clinical improvement was noted preferring the chisel ( P = 0.12) to the burr ( P = 0.65), and whenever C2-C3 was decompressed, whether hyperostosis included that level ( P = 0.15). Use of curved chisel reduced the surgical times ( P = 0.02) and, together with the nasogastric tube, the risk of complications, while bone removal involving 3 levels or more ( P = 0.04) and shorter waiting times for surgery ( P < 0.001) positively influenced a complete swallowing recovery. Early decompressions were preferred, resulting in 66.6% of patients reporting disappearance of symptoms within 7 days. One and two recurrences respectively at clinical and radiological follow-up were registered 18-30 months after surgery. Conclusion: The “age of DISH” counts more than patients’ age with timeliness of decompression being crucial in determining clinical outcome even with a preoperative mild dysphagia. Targeted bone resections could be reasonable in elderly patients, while in younger ones more extended decompressions should be preferred.
