Feasibility Study of Transanal Irrigation Using a Colostomy Irrigation System in Patients With Low Anterior Resection Syndrome.

BACKGROUND: Low anterior resection syndrome has a negative impact on quality of life. Intestinal irrigation is a method of lavage consisting of a scheduled evacuation. OBJECTIVE: This study aims to evaluate functional and quality-of-life outcomes in patients with low anterior resection syndrome after transanal irrigation using a colostomy irrigation system. DESIGN: This was a prospective case series. SETTINGS: This study presents a single-center experience at a tertiary oncological center in an upper-middle-income country. PATIENTS: Patients classified as having minor or major low anterior resection syndrome 12 months after their operation were selected. INTERVENTIONS: Transanal irrigation was performed using an ostomy irrigation kit. Questionnaires assessing patients' bowel function (low anterior resection syndrome and Wexner score) and quality of life (Short Form-36 questionnaire) were applied before and after treatment. MAIN OUTCOME MEASURES: The primary outcomes were low anterior resection syndrome score and quality-of-life improvement after a 12-month treatment. RESULTS: Of the 22 patients included, 20 had major and 2 had minor low anterior resection syndrome, with a median score of 39, especially high rates of incontinence for liquid stool (21; 95.5%), clustering (21; 95.5%), and urgency (17; 77.3%). All patients successfully completed the 3-day training, and there were no complications during the treatment. After the 12-month period, the median score was 8, with 90% of the patients classified as having "no syndrome" and great improvement in all domains of this score. The most improved quality-of-life sections were patient vitality (p = 0.025) and physical (p = 0.002), social (p = 0.001), and emotional aspects (p = 0.001). LIMITATIONS: The study was limited by its small sample size and the limited follow-up period. CONCLUSIONS: This study presents a safe implementation protocol of an ostomy irrigation device for transanal irrigation. It also adds to the literature that transanal irrigation is a safe, effective, and easily implemented procedure for patients with low anterior resection syndrome with a significant improvement in quality of life.

PRIMARY TUMOR LYMPHOVASCULAR INVASION NEGATIVELY AFFECTS SURVIVAL AFTER COLORECTAL LIVER METASTASIS RESECTION?

BACKGROUND: About 50% of the patients with colorectal adenocarcinoma will present with liver metastasis and 20% are synchronic. Liver resection is associated with improvement in survival in comparison to chemotherapy alone. AIM: To analyze the overall survival in patients submitted to liver resection of colorectal cancer metastasis and prognostic factors related to the primary and secondary tumors. METHODS: A retrospective analysis of a prospectively maintained database regarding demographic, primary tumor and liver metastasis characteristics. RESULTS: There were 84 liver resections due to colorectal cancer metastasis in the period. The 5-year disease-free and overall survivals were 27.5% and 48.8% respectively. The statistically significant factors for survival were tumor grade (p=0.050), lymphovascular invasion (p=0.021), synchronous metastasis (p=0.020), as well as number (p=0.004), bilobar distribution (p=0.019) and diameter of the liver metastasis over 50 mm (p=0.027). Remained as independent negative predictive factors: lymphovascular invasion (HR=2.7; CI 95% 1.106-6.768; p=0.029), synchronous metastasis (HR=2.8; CI 95% 1.069-7.365; p=0.036) and four or more liver metastasis (HR=1.7; CI 95% 1.046-2.967; p=0.033). CONCLUSION: The resection of liver metastasis of colorectal adenocarcinoma leads to good survival rates. Lymphovascular invasion was the single prognostic factor related to the primary tumor. Synchronous disease and four or more metastasis were the most significant factors related to the secondary tumor.

RESUMO Racional: Cerca de metade dos pacientes com adenocarcinoma colorretal apresentará metástases hepáticas. Apesar da superioridade do tratamento cirúrgico, os pacientes com elas compõem um grupo muito heterogêneo. Objetivo: Descrever o impacto de fatores relacionados ao tumor primário e ao secundário na sobrevida após ressecção de metástases hepáticas colorretais. Métodos: Análise retrospectiva de base de dados mantida prospectivamente de pacientes operados. Resultados: Foram realizadas 84 hepatectomias para ressecção de metástases hepáticas de adenocarcinoma colorretal em 73 pacientes no período. A sobrevida global e livre de doença em cinco anos foram de 48,8 e 27,5%, respectivamente. Os principais preditores de sobrevida foram grau de diferenciação (p=0,050) e invasão angiolinfática (p=0,021) do tumor primário, metástases sincrônicas (p=0,020), número (p=0,004), distribuição bilobar (p=0,019) e diâmetro máximo maior que 50 mm (p=0,027) dos nódulos hepáticos. Foram significativos a presença de invasão angiolinfática (HR=2,7; IC 95% 1,106-6,768; p=0,029), metástases sincrônicas (HR=2,8; IC 95% 1,069-7,365; p=0,036) e número de nódulos hepáticos igual ou superior a quatro (HR=1,7; IC 95% 1,046-2,967; p=0,033). Conclusão: A ressecção de metástases hepáticas de adenocarcinoma colorretal proporciona melhora da sobrevida e os principais fatores prognósticos foram a invasão angiolinfática no tumor primário, metástases sincrônicas e quatro ou mais nódulos hepáticos.

Preoperative prognostic factors in patients with ductal adenocarcinoma of the head of the pancreas. / Fatores prognósticos pré-operatórios em pacientes com adenocarcinoma ductal da cabeça do pâncreas.

OBJECTIVE: To identify the preoperative prognostic factors influencing pancreatic cancer survival following curative resection in a single Brazilian institution. METHODS: From 2005 to 2018, preoperative clinic, demographic and laboratory data were prospectively collected. Survival analysis was performed by the Kaplan-Meier method and the comparison between curves by the log-rank test. For multivariate analysis, the Cox regression model was used. RESULTS: advanced age (p = 0.012) and previous history of cancer (p = 0.026) were the preoperative factors, according to the univariate analysis, that significantly impacted survival. Patients with preoperative serum levels of CA 19.9 from 38 to 554 U/mL had a 3.15 times higher chances of death (HR 3.15; 95% CI 1.01-9.82; p = 0.047), whereas patients with the marker above 554 U/mL were 3.96 times more likely than those with the normal level (HR 3.96; 95% CI 1.19-13.10; p = 0.024), by using the multivariate analysis. Patients with previous comorbidities had a 2.90 times higher chance of death than those without associated conditions (HR 2.90; 95% CI 1.10-7.67; p = 0.032). CONCLUSION: Preoperative factors related to the worst prognosis after pancreatic ductal adenocarcinoma resection were advanced age, presence of comorbidities, previous history of cancer and elevated preoperative serum CA 19.9.

OBJETIVOS: Identificar fatores prognósticos pré-operatórios relacionados à sobrevida de pacientes com adenocarcinoma ductal da cabeça de pâncreas (ADCP) submetidos a tratamento cirúrgico com intenção curativa em uma única instituição brasileira. MÉTODO: No período de 2005 a 2018, dados clinicodemográficos e laboratoriais pré-operatórios foram prospectivamente coletados. A análise de sobrevida foi feita pelo método de Kaplan-Meier e a comparação entre as curvas pelo teste de log-rank. Para a análise multivariada utilizou-se o modelo de regressão de Cox. RESULTADOS: Os fatores pré-operatórios com impacto significativo na sobrevida à análise univariada foram a idade maior ou igual a 70 anos (p=0,012) e história pessoal prévia positiva para câncer (p=0,026). A análise multivariada, pacientes com níveis séricos pré-operatórios de CA 19.9 de 38 a 554 U/ml apresentaram 3,15 vezes maior chance de óbito (HR 3,15; IC 95% 1,01 - 9,82; p=0,047), enquanto que os pacientes com o marcador acima de 554 U/ml evoluíram com chance 3,96 vezes maior de óbito que aqueles com a dosagem normal (HR 3,96; IC 95% 1,19 - 13,10; p=0,024). Pacientes com comorbidades prévias evoluíram com chance 2,90 vezes superior de óbito que doentes sem condições associadas (HR 2,90; IC 95% 1,10 - 7,67; p=0,032). CONCLUSÃO: O ADCP mostrou ser doença agressiva para a qual os fatores pré-operatórios de pior prognóstico foram idade avançada, presença de comorbidades, história prévia de câncer e nível sérico de CA 19.9 elevado no pré-operatório.

PRE-OPERATIVE GASTRIC GIST DOWNSIZING: THE IMPORTANCE OF NEOADJUVANT THERAPY.

INTRODUCTION: Gastric gastrointestinal tumors (GIST) are a rare and usually asymptomatic neoplasm that can present as abdominal mass in more advanced scenarios. Since surgical resection is the main aspect of the treatment, locally advanced tumors require multivisceral resection and, therefore, higher postoperative morbidity and mortality. OBJECTIVE: To perform a review the literature on the topic, with emphasis on the neoadjuvant therapy. METHODS: Literature review on the Medline database using the following descriptors: gastrointestinal stromal tumors, neoadjuvant therapy, imatinib mesylate and molecular targeted therapy. RESULTS: Surgical resection remains the cornerstone for the treatment of GISTs; however, tyrosine kinase inhibitors have improved survival as an adjuvant therapy. More recently, neoadjuvant therapy have been described in the treatment of locally advanced tumors in order to avoid multivisceral resection. CONCLUSION: Despite surgical resection remains as the most important aspect of the treatment of GISTs, adjuvant and neoadjuvant therapy with tyrosine kinase inhibitors have shown to both improve survival and resectability, respectively.

RESUMO Introdução: O tumor estromal gastrintestinal (GIST) gástrico é neoplasia que cursa, por vezes, com apresentação assintomática, se manifestando como massa abdominal, relacionada a casos mais avançados. Esses, por sua vez, exigem tratamento com operações maiores e que cursam com mais alta morbimortalidade. Objetivo: Revisar e atualizar o tratamento do GIST gástrico, com enfoque na relevância do tratamento neoadjuvante. Método: Revisão da literatura utilizando a base de dados Medline/PubMed. Utilizaram-se os seguintes descritores: gastrointestinal stromal tumors, neoadjuvant therapy, imatinib mesylate e molecular targeted therapy. Dos artigos selecionados, 20 foram incluídos. Resultados: O tratamento cirúrgico é pilar fundamental para a cura do GIST. Entretanto, após a introdução do mesilato de imatinibe, classicamente utilizado como terapia adjuvante, houve mudança no manejo do GIST, permitindo aumento da sobrevida e diminuição da recorrência. A aplicação como terapia neoadjuvante é mais recente, e visa evitar procedimentos maiores sem, no entanto, prejudicar o resultado oncológico. Conclusão: A ressecção cirúrgica possui papel bem estabelecido no tratamento do GIST, inclusive com abordagem laparoscópica. O tratamento adjuvante com mesilato de imatinib, durante os primeiros três anos após a operação, mostra-se como opção segura para casos com elevado risco de recidiva. A terapia neoadjuvante é opção promissora para casos de tumor localmente avançado, permitindo ressecções menores e com menor morbimortalidade operatória.

Retrospective analysis of 103 diaphragmatic injuries in patients operated in a trauma center. / Análise retrospectiva de 103 casos de lesão diafragmática operados em um centro de trauma.

OBJECTIVE:: to analyze the factors associated with death in patients with diaphragmatic injury treated at a trauma reference hospital. METHODS:: we conducted a retrospective study of patients with diaphragm injury attended at the Risoleta Tolentino Neves Hospital of the Federal University of Minas Gerais, between January 2010 and December 2014. We used The Collector® database of trauma records (MD, USA). We gathered data on demographics, location of the diaphragmatic lesion, site and number of associated lesions, type of therapeutic approach, complications and Injury Severity Score (ISS). The variable of interest was the occurrence of death. RESULTS:: we identified 103 patients and mortality was 16.5%. Penetrating lesions occurred in 98% of patients. Univariate analysis showed a mortality higher in patients whose treatment was non-operative, without closing of the defect (p=0.023), and lower in patients submitted to diaphragmatic suturing (p<0.001). The increase in the number of lesions was associated with an increase in mortality (p=0.048). In multivariate analysis, ISS>24 (OR=4.0, p=0.029) and diaphragmatic suturing (OR=0.76, p<0.001) were associated with mortality. CONCLUSION:: The findings indicate that the traumatic rupture of the diaphragm rarely presents as an isolated lesion, being frequently associated with injuries of other organs, especially the liver and hollow viscera. Mortality was higher among those with ISS>24.

Análise retrospectiva de 103 casos de lesão diafragmática operados em um centro de trauma / Retrospective analysis of 103 diaphragmatic injuries in patients operated in a trauma center

RESUMO Objetivo: analisar os fatores associados ao óbito em pacientes com lesão diafragmática atendidos em hospital de referência para o trauma. Métodos: estudo retrospectivo de pacientes com lesão do diafragma atendidos no Hospital Risoleta Tolentino Neves da Universidade Federal de Minas Gerais entre janeiro de 2010 e dezembro de 2014. Foi utilizado o Banco de Registros de Trauma Collector® (MD, USA). Utilizaram-se dados demográficos, localização da lesão diafragmática, lesões associadas de outros órgãos, número de lesões associadas, tipo de abordagem terapêutica, complicações e o escore de gravidade Injury Severity Score (ISS). A variável de interesse foi a ocorrência de óbito. Resultados: foram identificados 103 pacientes e a incidência de óbito foi de 16,5%. Lesões penetrantes ocorreram em 98% dos pacientes. Em análise univariada a mortalidade foi maior em pacientes cujo tratamento foi não operatório, sem rafia (p=0,023), e menor em pacientes submetidos à rafia diafragmática (p<0,001). O aumento do número de lesões associou-se ao aumento da incidência de óbitos (p=0,048). Em análise multivariada, ISS>24 (OR=4,0; p=0,029) e rafia do diafragma (OR=0,76; p<0,001) associaram-se à mortalidade. Conclusão: os achados indicam que a ruptura traumática do diafragma raramente se apresenta como lesão isolada, estando associada frequentemente à lesão de outros órgãos, especialmente fígado e vísceras ocas. Pode-se afirmar que a mortalidade foi mais elevada entre aqueles com ISS>24.

VIPoma pancreático tratado com pancreatectomia distal e preservação esplênica com ligadura da artéria esplênica / Pancreatic VIPoma treated with distal pancreatectomy and splenic preservation with ligature of splenic artery

O VIPoma é um tumor neuroendócrino de baixa malignidade derivado das células das ilhotas não-beta do pâncreas, apresenta incidência de 1:10.000.000 pessoas na população e sua localização mais comum é no corpo e cauda do pâncreas. Seu tratamento curativo é cirúrgico, sendo geralmente realizada a pancreatectomia distal com esplenectomia. O caso relatado foi o de uma paciente do sexo feminino, de 31 anos, diagnosticada com VIPoma pancreático. O tratamento realizado foi a pancreatectomia distal com preservação esplênica e ligadura da artéria esplênica. A preservação esplênica diminui a morbidade perioperatória, sem prejudicar o resultado oncológico nos tumores de baixo grau de malignidade.

VIPoma is a low grade malignancy neuroendocrine tumor derived from non-beta pancreatic islet cells, it has an incidence of 1:10.000.000 individuals in the general population and its commoner location is in the body and tail of the pancreas. The curative treatment is surgery, and distal pancreatectomy with splenectomy is usually the employed technique. The case reported was of a female patient, 31 years-old, diagnosed with pancreatic VIPoma. The chosen treatment was distal pancreatectomy with splenic preservation and ligature of the splenic artery. Splenic preservation reduces the perioperatory morbidity, with no prejudice to the oncologic effect in the low grade malignancy tumors.

Pregnancy after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in pseudomyxoma peritonei.

Pseudomyxoma peritonei is usually a benign tumor that is slightly more common in women. However, it requires aggressive surgical treatment and chemotherapy, often compromising future reproductive function. This report presents a case of pregnancy in a 35-year-old woman who underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for treatment of pseudomyxoma peritonei. The tumor was diagnosed during a laparoscopic examination on a workup for infertility in 2008. Two months later, she underwent a peritonectomy followed by hyperthermic intraperitoneal chemotherapy and, regarding her will to conceive, ovaries and fallopian tubes were preserved. In March 2011, she went through an in vitro fertilization followed by an uneventful pregnancy and delivered a healthy child 39 weeks later. Ovaries are usually resected during the cytoreductive surgery, since they are common sites for neoplastic implants, and, even when not performed, little is known about the effects of local chemotherapy on female fertility. The largest international survey on this matter only describes seven similar cases. This particular report not only describes a rare condition but also adds to the upcoming discussion about whether ovaries can be preserved in specific situations, therefore keeping the prospect of conceiving after this treatment.
