Pancreatic solid-pseudopapillary neoplasm in patients with familial adenomatous polyposis / Neoplasia sólida pseudopapilífera pancreática em pacientes com polipose adenomatosa familiar

ABSTRACT BACKGROUND: Solid pseudopapillary neoplasm of the pancreas is an uncommon pancreatic tumor, which is more frequent in young adult women. Familial adenomatous polyposis is a genetic condition associated with colorectal cancer that also increases the risk of developing other tumors as well. AIM: The aim of this study was to discuss the association of familial adenomatous polyposis with solid pseudopapillary neoplasm of the pancreas, which is very rare. METHODS: We report two cases of patients with familial adenomatous polyposis who developed solid pseudopapillary neoplasm of the pancreas of the pancreas and were submitted to laparoscopic pancreatic resections with splenic preservation (one male and one female). RESULTS: ß-catenin and Wnt signaling pathways have been found to play an important role in the tumorigenesis of solid pseudopapillary neoplasm of the pancreas, and their constitutive activation due to adenomatous polyposis coli gene inactivation in familial adenomatous polyposis may explain the relationship between familial adenomatous polyposis and solid pseudopapillary neoplasm of the pancreas. CONCLUSION: Colonic resection must be prioritized, and a minimally invasive approach is preferred to minimize the risk of developing desmoid tumor. Pancreatic resection usually does not require extensive lymphadenectomy for solid pseudopapillary neoplasm of the pancreas, and splenic preservation is feasible.

RESUMO RACIONAL: A neoplasia sólida pseudopapilífera do pâncreas é um tumor pancreático incomum, mais frequente em mulheres jovens. A polipose adenomatosa familiar, por sua vez, é uma condição genética associada a câncer colorretal e que também aumenta o risco de desenvolvimento de outros tumores. OBJETIVOS: Discutir a associação entre polipose adenomatosa familiar e neoplasia sólida pseudopapilífera, que é bastante rara. MÉTODOS: Reportamos dois casos de pacientes com polipose adenomatosa familiar, um homem e uma mulher, que desenvolveram neoplasia sólida pseudopapilífera do pâncreas e foram submetidos a ressecção laparoscópica com preservação esplênica. RESULTADOS: As vias de sinalização da ß-catenina e Wnt tem um papel importante na tumorigênese da neoplasia sólida pseudopapilífera, e sua ativação constitutiva devido a inativação do gene adenomatous polyposis coli na polipose adenomatosa familiar pode explicar a relação entre polipose adenomatosa familiar e neoplasia sólida pseudopapilífera. CONCLUSÕES: A ressecção do cólon deve ser priorizada, com preferência pela abordagem minimamente invasiva para minimizar o risco de desenvolvimento de tumor desmoide. A ressecção pancreática geralmente não requer linfadenectomia extensa para neoplasia sólida pseudopapilífera, portanto, a preservação esplênica é factível.

The impact of multivisceral liver resection on short- and long-term outcomes of patients with colorectal liver metastasis: A systematic review and meta-analysis

Abstract The impact of Multivisceral Liver Resection (MLR) on the outcome of patients with Colorectal Liver Metastasis (CRLM) is unclear. The present systematic review aimed to compare patients with CRLM who underwent MLR versus standard hepatectomy regarding short- and long-term outcomes. MLR is a feasible procedure but has a higher risk of major complications. MLR did not negatively affect long-term survival, suggesting that an extended resection is an option for potentially curative treatment for selected patients with CRLM.

Evaluation of elbow flexion following free muscle transfer from the medial gastrocnemius or transfer from the latissimus dorsi, in cases of traumatic injury of the brachial plexus / Avaliação da flexão do cotovelo após transferência muscular livre do gastrocnêmio medial ou transferência do latíssimo do dorso na lesão traumática do plexo braquial

To compare the gain in elbow flexion in patients with traumatic injury of the brachial plexus following muscle transfer from latissimus dorsi with the gain following free muscle transfer from the medial belly of the gastrocnemius. METHODS: This was a retrospective study in which the medical files of a convenience sample of 13 patients operated between 2000 and 2010 were reviewed. Group 1 comprised seven patients who underwent transfers from the gastrocnemius and group 2 (controls) comprised six patients who underwent transfers from the latissimus dorsi. The following functions were evaluated: (1) range of motion (ROM) of elbow flexion, in degrees, using manual goniometry and (2) grade of elbow flexion strength, using a muscle strength scale. Satisfactory results were defined as: (1) elbow flexion ROM ≥ 80° and (2) elbow flexion strength ≥ M3. The Fisher exact and Kruskal-Wallis tests were used (p < 0.05). RESULTS: The patients' mean age was 32 years (range: 17-56) and 72% had been involved in motorcycle accidents. Elbow flexion strength ≥ M3 was observed in seven patients (100%) in group 1 and in five patients (83.3%) in group 2 (p = 0.462). None of the patients presented M5, and one patient (16.7%) in group 2 had a poor result (M2). Elbow flexion ROM with a gain ≥ 80° (daily functions) was found in six patients (86%) in group 1 and in three patients (50%) in group 2 ( p = 0.1). CONCLUSION: The patients in group 1 had greater gains in strength and ROM than did those in group 2, but without statistical significance. Thus, transfers from the gastrocnemius become a new surgical option, if other techniques cannot be used.

Comparar o ganho de flexão do cotovelo em pacientes com lesão traumática do plexo braquial após transferência muscular do latíssimo dorsal (TMLD) com a transferência muscular livre do ventre medial do gastrocnêmio (TMLGM). METÓDOS: Estudo retrospectivo, revisão de prontuários, amostra de conveniência, com 13 pacientes operados, entre 2000 e 2010. Grupo 1 (TMLGM) com sete pacientes e grupo 2 ou controle (TMLD) com seis. Função avaliada: 1) amplitude de movimento (ADM) em graus da flexão do cotovelo, goniometria manual; 2) grau de força de flexão do cotovelo, por escala de força muscular. Satisfatórios: 1) ADM: flexão do cotovelo ≥ 80°; 2) Força: flexão do cotovelo ≥ M3. Testes exato de Fisher e Kruskal-Wallis (p < 0,05). RESULTADOS: Média de idade foi de 32 anos (17 a 56). Acidente de moto em 72%. Força de flexão do cotovelo ≥ M3 no grupo 1 em sete pacientes (100%) e o grupo 2 em cinco (83,3%) (p = 0,462). Não tivemos M5 e o grupo 2 apresentou um paciente (16,7%) com resultado ruim M2. ADM na flexão do cotovelo com ganho ≥ 80° (funções diárias) foram encontrados no grupo 1 em seis pacientes (86%) e no grupo 2 em três (50%) (p = 0,1). CONCLUSÃO: Pacientes do grupo 1 tiveram um ganho maior de força e ADM, quando comparados com os do grupo 2, sem significado estatístico. Assim, TMLGM se torna uma nova opção cirúrgica, caso não possam ser aplicadas outras técnicas.

To evaluate sociodemographic and clinical aspects of patients undergoing operations due to traumatic lesions of the brachial plexus. METHOD: This was a retrospective study in which the medical files of a convenience sample of 48 patients operated between 2000 and 2010 were reviewed. The following were evaluated: (1) range of motion (ROM) of the shoulder, elbow and wrist/hand, in degrees; (2) grade of strength of the shoulder, elbow and wrist/hand; (3) sensitivity; and (4) visual analogue scale (VAS) (from 0 to 10). The Student's t, chi-square, Friedman, Wilcoxon and Kruskal-Wallis tests were used (p < 0.05). RESULTS: The patients' mean age was 30.6 years; 60.4% of them had suffered motorcycle accidents and 52.1%, multiple trauma. The mean length of time until surgery was 8.7 months (range: 2-48). Thirty-one patients (64.6%) presented complete rupture of the plexus. The frequent operation was neurosurgery in 39 cases (81.3%). The ROM achieved was ≥30° in 20 patients (41.6%), with a range from 30° to 90° and mean of 73° (p = 0.001). Thirteen (27.1%) already had shoulder strength ≥M3 (p = 0.001). Twenty-seven patients (56.2%) had elbow flexion ≥80°, with a range from 30° to 160° and mean of 80.6° (p < 0.001). Twenty-two had strength ≥M3 (p < 0.001). Twenty-two patients (45.8%) had wrist extension ≥30° starting from flexion of 45°, with a range from 30° to 90° and mean of 70° (p = 0.003). Twenty-seven (56.3%) presented wrist/hand extension strength ≥M3 (p = 0.002). Forty-five (93.8%) had hypoesthesia and three (6.2%) had anesthesia (p = 0.006). The initial VAS was 4.5 (range: 1.0-9.0) and the final VAS was 3.0 (range: 1.0-7.0) (p < 0.001). CONCLUSION: Traumatic lesions of the brachial plexus were more prevalent among young adults (21-40 years), men, people living in urban areas, manual workers and motorcycle accidents, with multiple trauma and total rupture of the plexus. Neurosurgery, with a second procedure consisting of muscle-tendon transfer, was the commonest operation. Surgery for traumatic lesions of the brachial plexus resulted in significant improvement in the ROM and strength of the shoulder, elbow and wrist/hand, improvement of the sensitivity of the limb affected and reduction of the final pain.
