RESUMEN

BACKGROUND: Clinical complete responders after chemoradiation for rectal cancer are increasingly being managed by a watch-and-wait strategy. Nonetheless, a significant proportion will experience a local regrowth, and the long-term oncological outcomes of these patients is not totally known. OBJECTIVE: The purpose of this study was to analyze the outcomes of patients who submitted to a watch-and-wait strategy and developed a local regrowth, and to compare these results with sustained complete clinical responders. DESIGN: This was a retrospective study. SETTING: Single institution, tertiary cancer center involved in alternatives to organ preservation. PATIENTS: Patients with a biopsy-proven rectal adenocarcinoma (stage II/III or low lying cT2N0M0 at risk for an abdominoperineal resection) treated with chemoradiation who were found at restage to have a clinical complete response. INTERVENTIONS: Rectal cancer patients treated with chemoradiation who underwent a watch-and-wait strategy (without a full thickness local excision) and developed a local regrowth were compared to the remaining patients of the watch-and-wait strategy. MAIN OUTCOME MEASURES: Overall survival between groups, incidence of regrowth' and results of salvage surgery. RESULTS: There were 67 patients. Local regrowth occurred in 20 (29.9%) patients treated with a watch-and-wait strategy. Mean follow-up was 62.7 months. Regrowth occurred at mean 14.2 months after chemoradiation, half of them within the first 12 months. Patients presented with comparable initial staging, lateral pelvic lymph-node metastasis, and extramural venous invasion. The regrowth group had a statistically nonsignificant higher incidence of mesorectal fascia involvement (35.0% vs 13.3%, p = 0.089). All regrowths underwent salvage surgery, mostly (75%) a sphincter-sparing procedure. 5-year overall survival was 71.1% in patients with regrowth and 91.1% in patients with a sustained complete clinical response (p = 0.027). LIMITATIONS: This study was limited by its retrospective evaluation of patient selection for a watch-and-wait strategy and outcomes, as well as its small sample size. CONCLUSIONS: Local regrowth is a frequent event when following a watch-and-wait policy (29.9%); however, patients could undergo salvage surgical treatment with adequate pelvic control. In this series, overall survival showed a statistically significant difference from patients managed with a watch-and-wait strategy who experienced a local regrowth compared to those who did not.

No obstante, una proporción significativa experimentará un rebrote local y los resultados oncológicos a largo plazo de estos pacientes, no se conocen por completo.OBJETIVO:El propósito de este estudio, fue analizar los resultados de los pacientes sometidos a una estrategia de observación y espera, que desarrollaron un rebrote local, y comparar estos resultados con respondedores clínicos completos sostenidos.DISEÑO:Este fue un estudio retrospectivo.ENTORNO CLINICO.Institución única, centro oncológico terciario involucrado en alternativas a la preservación de órganos.PACIENTES:Pacientes con un adenocarcinoma de recto comprobado por biopsia (estadio II / III o posición baja cT2N0M0, en riesgo de resección abdominoperineal), tratados con quimiorradiación, y que durante un reestadiaje, presentaron una respuesta clínica completa.INTERVENCIONES:Los pacientes con cáncer de recto tratados con quimiorradiación, sometidos a una estrategia de observación y espera (sin una escisión local de espesor total) y que desarrollaron un rebrote local, se compararon con los pacientes restantes de la estrategia de observación y espera.PRINCIPALES MEDIDAS DE VALORACION:Supervivencia global entre los grupos, incidencia de rebrote y resultados de la cirugía de rescate.RESULTADOS:Fueron 67 pacientes. El rebrote local ocurrió en 20 (29,9%) pacientes tratados con una estrategia de observación y espera. El seguimiento medio fue de 62,7 meses. El rebrote se produjo a la media de 14,2 meses después de la quimiorradiación, la mitad de ellos dentro de los primeros 12 meses. Los pacientes se presentaron con una estadificación inicial comparable, metástasis en los ganglios linfáticos pélvicos laterales e invasión venosa extramural. El grupo de rebrote tuvo una mayor incidencia estadísticamente no significativa de afectación de la fascia mesorrectal (35,0 vs 13,3%, p = 0,089). Todos los rebrotes se sometieron a cirugía de rescate, en su mayoría (75%) con procedimiento de preservación del esfínter. La supervivencia global a 5 años fue del 71,1% en pacientes con rebrote y del 91,1% en pacientes con una respuesta clínica completa sostenida (p = 0,027).LIMITACIONES:Evaluación retrospectiva de la selección de pacientes para una estrategia y resultados de observar y esperar, tamaño de muestra pequeño.CONCLUSIONES:El rebrote local es un evento frecuente después de la política de observación y espera (29,9%), sin embargo los pacientes podrían someterse a un tratamiento quirúrgico de rescate con un adecuado control pélvico. En esta serie, la supervivencia global mostró una diferencia estadísticamente significativa de los pacientes manejados con una estrategia de observación y espera que experimentaron un rebrote local, en comparación con los que no lo hicieron.

RESUMEN

PURPOSE: Transanal endoscopic microsurgery (TEM) is a safe and efficient minimally invasive treatment for rectal benign and early malignant neoplasia, but postoperative complications may be severe. We aimed to evaluate the risk factors related to the incidence, severity, and time course of postoperative complications of TEM. METHODS: This is a prospective study of postoperative complications in 53 patients (>18 years old) with benign or early rectal neoplasia who underwent TEM with curative intention or, for higher stages, palliation. Outcome measures included age, sex, American Society of Anesthesiologists score, neoadjuvant chemoradiotherapy, lesion height and size, pathologic margins, tumor histology, and suture type. RESULTS: Overall morbidity was 50 %. Temporary fecal incontinence was the most frequent complication (17.3 %). Complication rates of Clavien-Dindo grades I and II were 21.1 % and those of grades III and IV 3.8 %. Of patients with complications, more had lesions under the first rectal valve than over the first valve (61.54 % vs 38.46 %, p = 0.04). Patients submitted to chemoradiotherapy had a 24-fold greater chance of presenting grade II complications (p = 0.002). When the surgical defect was treated using the TEM device to perform the suture, the chance of having grade III complications was reduced 16-fold (p = 0.04). Fifty-three percent of complications occurred in the first 10 days and 95 % within 20 days. CONCLUSIONS: Postoperative complications after transanal endoscopic microsurgery for the treatment of rectal neoplasia are frequent, acceptable, and usually controllable with pharmacologic treatment. Over time the nature of complications is continuous, centered on the first 20 days after surgery.

RESUMEN

BACKGROUND: Due to the lack of normal standards of anorectal manometry in Brazil, data used are subject to normality patterns described at different nationalities. AIM: To determine the values and range of the parameters evaluated at anorectal manometry in people, at productive age, without pelvic floor disorders comparing the parameters obtained between male and female. METHODS: Prospective analysis of clinical data, such as gender, age, race, body mass index (BMI) and anorectal manometry, of volunteers from a Brazilian university reference in pelvic floor disorders. RESULTS: Forty patients were included, with a mean age of 45.5 years in males and 37.2 females (p=0.43). According to male and female, respectively in mmHg, resting pressures were similar (78.28 vs. 63.51, p=0.40); squeeze pressures (153.89 vs. 79.78, p=0.007) and total squeeze pressures (231.27 vs. 145.63, p=0.002). Men presented significantly higher values of anorectal squeeze pressures, as well as the average length of the functional anal canal (2.85 cm in male vs. 2.45 cm in female, p=0.003). CONCLUSIONS: Normal sphincter pressure levels in Brazilians differ from those used until now as normal literature standards. Male gender has higher external anal sphincter tonus as compared to female, in addition a greater extension of the functional anal canal.

RESUMEN

BACKGROUND: Recently, with the performance of minimally invasive procedures for the management of colorectal disorders, it was allowed to extend the indication of laparoscopy in handling various early and late postoperative complications. AIM: To present the experience with laparoscopic reoperations for early complications after laparoscopic colorectal resections. METHODS: Patients undergoing laparoscopic colorectal resections with postoperative surgical complications were included and re-treated laparoscopically. Selection for laparoscopic approach were those cases with early diagnosis of complications, hemodynamic stability without significant abdominal distention and without clinical comorbidities that would preclude the procedure. RESULTS: In four years, nine of 290 (3.1%) patients who underwent laparoscopic colorectal resections were re-approached laparoscopically. There were five men. The mean age was 40.67 years. Diagnoses of primary disease included adenocarcinoma (n=3), familial adenomatous polyposis (n=3), ulcerative colitis (n=1), colonic inertia (n=1) and chagasic megacolon (n=1). Initial procedures included four total proctocolectomy with ileal pouch anal anastomosis; three anterior resections; one completion of total colectomy; and one right hemicolectomy. Anastomotic dehiscence was the most common complication that resulted in reoperations (n=6). There was only one case of an unfavorable outcome, with death on the 40th day of the first approach, after consecutive complications. The remaining cases had favorable outcome. CONCLUSION: In selected cases, laparoscopic access may be a safe and minimally invasive approach for complications of colorectal resection. However, laparoscopic reoperation must be cautiously selected, considering the type of complication, patient's clinical condition and experience of the surgical team.

RESUMEN

BACKGROUND: Since 1990 it was proposed that distal and proximal location of colon cancer might follow different biological, epidemiology, pathology and prognosis, probably due to embryologic different development of the two segments of the colon, which may represent two separate disease entities. These differences might have consequences for the treatment of patients with colorectal cancer. AIM: To compare the characteristics between patients with right and left colon cancer, with severity and tumor characteristic that influence in the survival of these patients. METHOD: Were evaluated the outcomes of surgical treatment of patients with colon cancer with data collected retrospectively from prospectively collected database. RESULTS: The tumor's side did not influence survival time of patients with colon cancer (p=0.112) in the regression model. Only the diseases stage leads to influence on survival time; patients with right colon cancer have more advanced staging (III or IV) and present a risk of death greater in 3.23 times. CONCLUSION: This analysis provides evidence that the prognosis of localized left-sided colon cancer is better compared to right-sided colon cancer. Also, the patients with right colon cancer have more advanced stage, mucinous tumor and are older.

RESUMO Racional: Devido à falta de padrões normais de manometria anorretal no Brasil, os dados utilizados estão sujeitos a padrões de normalidade descritos em diferentes nacionalidades . Objetivo: Determinar os valores e a faixa da manometria anorretal de pessoas em idade produtiva, sem distúrbios do assoalho pélvico, comparando os parâmetros obtidos entre homens e mulheres. Métodos: Análise prospectiva de dados clínicos, como gênero, idade, raça, índice de massa corporal (IMC) e manometria anorretal, de voluntários de uma referência universitária brasileira em distúrbios do assoalho pélvico. Resultados: Quarenta pessoas foram incluídas, com idade média de 45,5 anos nos homens e 37,2 nas mulheres (p=0,43). De acordo com homens e mulheres, respectivamente em mmHg, as pressões de repouso foram semelhantes (78,28 vs. 63,51, p=0,40); pressões de contração (153,89 vs. 79,78, p=0,007) e pressão total de compressão (231,27 vs. 145,63, p=0,002). Os homens apresentaram valores significativamente maiores de contração esfincteriana, assim como o comprimento médio do canal anal funcional (2,85 cm nos homens vs. 2,45 cm nas mulheres, p=0,003). Conclusões: Os níveis normais de pressão esfincteriana no Brasil diferem dos utilizados até o momento como padrão normal da literatura. O gênero masculino apresenta maior tônus ​​do esfíncter anal externo em relação ao feminino, além de maior extensão do canal anal funcional

RESUMO Racional: A realização de procedimentos minimamente invasivos para o manejo de distúrbios colorretais, possibilitou ampliar a indicação de laparoscopia para o manuseio de diversas complicações pós-operatórias precoces e tardias. Objetivo: Apresentar a experiência com reoperações laparoscópicas para complicações precoces após ressecções colorretais laparoscópicas. Métodos: Foram incluídos pacientes submetidos a ressecções colorretais laparoscópicas que apresentaram complicações cirúrgicas no pós-operatório abordadas por via laparoscópica. Os pacientes selecionados foram aqueles com diagnóstico precoce de complicações, estabilidade hemodinâmica sem distensão abdominal significativa e sem comorbidades clínicas que impedissem o procedimento. Resultados: Em quatro anos, nove de 290 (3,1%) pacientes submetidos a ressecções colorretais laparoscópicas foram reabordados pela mesma via de acesso. Havia cinco pacientes do sexo masculino e idade média foi de 40,67 anos. Os diagnósticos de doença primária incluíram adenocarcinoma (n=3), polipose adenomatosa familiar (n=3), colite ulcerativa (n=1), inércia colônica (n=1) e megacólon chagásico (n=1). Os procedimentos iniciais incluíram quatro proctocolectomias totais com anastomose íleo-anal em bolsa ileal; três ressecções anteriores; uma totalização de colectomia total; e uma hemicolectomia direita. A deiscência da anastomose foi a complicação mais comum que resultou em reoperação (n=6). Houve apenas um caso de desfecho desfavorável, com óbito no 40º dia da primeira abordagem após complicações consecutivas. Os demais casos tiveram desfecho favorável . Conclusão: Em casos selecionados, o acesso laparoscópico pode representar alternativa de abordagem segura e minimamente invasiva para complicações da ressecção colorretal. No entanto, a reoperação laparoscópica deve ser cuidadosamente selecionada, considerando o tipo de complicação, a condição clínica do paciente e a experiência da equipe cirúrgica.

RESUMEN

The purpose of the present study was to determine the value of circular hemorrhoidectomy (procedure for prolapse and hemorrhoids [PPH]) on the basis of data collected prospectively during the initial experience of a group of Latin American surgeons. Between 2000 and 2001, PPH was performed using a circular stapler in 177 patients who had third- and fourth-degree hemorrhoidal disease. The average age of the patients was 47.7 years (range 26 to 85 years). Anal bleeding was the most common preoperative complaint (93.2%) followed by anal pain (60.2%), anal itching (43%), and constipation (41%). Hemorrhoids were classified as third degree in 132 patients (74%) and fourth degree in 45 patients (25.4%). Skin tags were detected in 86 patients (48.8%) and rectocele in 14 patients (7.9%). Data collected included patient demographics, type of anesthesia, and specific details of the surgery such as duration of the operation, distance from the staple line to the dentate line, need for complementary hemostasis, and any unexpected occurrences. Postoperative data collected included the degree of pain, which was evaluated on the basis of the type and dosage of analgesics required, laxative consumption, and the presence of bleeding, fever, urinary retention, or hematomas. Each patient completed a written questionnaire addressing these events. Patients returned for follow-up visits on days 7, 15, 30, and 90. Responses to pain, bleeding, fever, anal continence, recurrence of hemorrhoids, and level of satisfaction were compiled. The duration of the procedure ranged from 6 minutes to 2 hours (average 23 minutes), and most operations lasted no more than 20 minutes, with the exception of one that lasted 2 hours because of intraoperative bleeding. Intraoperative problems were minor. An additional one or a few sutures were required in 58.7% of patients to achieve perfect hemostasis. In 128 patients (72.3%) the hospital stay was less than 24 hours. Same-day surgery was chosen for 37 patients (20.9%). Pain was controlled with analgesia only using one to six doses of oral dipirona in 126 patients. Five patients were readmitted to the hospital: four for control of bleeding and one for conventional hemorrhoidectomy due to an acute episode of external hemorrhoidal thrombosis. At day 30, patients rated the efficacy of the procedure in alleviating preoperative symptoms as follows: 77.5% excellent; 16% good; 5.3% average, and 1.2% poor. At 3 months postoperatively no patient had had a recurrence of hemorrhoidal prolapse, and there were no instances of stenosis or anal incontinence. Surgeons also rated the efficacy of the procedure as excellent in 75%, good in 19.8%, average in 4.7%, and poor in 0.6%. With proper selection of patients and adequate stapling technique, stapled hemorrhoidectomy may be considered safe; it is easily learned, has a satisfactory degree of pain, and is well accepted by both patients and surgeons.

RESUMO Racional: Desde 1990, foi proposto que a localização distal e proximal do câncer de cólon pode seguir diferentes aspectos biológicos, epidemiológicos, patológicos e prognósticos. Essas diferenças podem ter consequências para o tratamento de pacientes com câncer colorretal. Objetivo: Comparar as características entre pacientes com câncer de cólon direito e esquerdo, com gravidade e características tumorais que influenciam na sobrevida desses pacientes. Método: Avaliação dos resultados do tratamento cirúrgico dos pacientes com câncer de cólon em longo prazo com dados coletados retrospectivamente. Resultados: O lado do tumor não influenciou o tempo de sobrevida (p=0,112) no modelo de regressão. Apenas o estágio da doença influencia no tempo de sobrevida. Os pacientes com câncer de cólon direito apresentam estadiamento mais avançado (III ou IV) e apresentam risco de morte 3,23 vezes maior. Conclusão: O prognóstico do câncer de cólon localizado no lado esquerdo é melhor comparado ao direito. Os pacientes com câncer de cólon direito têm estágio e idade mais avançados e tumor mucinoso.

RESUMEN

Transanal endoscopic microsurgery (TEM) provides a minimally invasive alternative to radical surgery for excision of benign and malignant rectal tumors. TEM aims to provide an alternative to conventional abdominal surgery (low anterior resection or abdominoperineal amputations), which carries not inconsiderable morbidity and mortality. Based on review of the literature and in the authors experience, this review present the method and indications for TEM.


A microcirurgia endoscópica transanal (TEM) é procedimento alternativo minimamente invasivo ao tratamento cirúrgico radical para excisão de tumores benignos e malignos do reto. Ela oferece possibilidade operatória aos procedimentos cirúrgicos convencionais (ressecção anterior baixa ou amputações abdominoperineais), as quais acarretam alta morbimortalidade. Baseada na revisão da literatura e na experiência própria dos autores, esta revisão tem por objetivo apresentar o método e as indicações para a TEM.

RESUMEN

The case of a patient with blue rubber bleb nevus syndrome who is infected by acquired immunodeficiency syndrome virus due to multiple blood transfusions is presented. This case shows that although it is a rare systemic disorder, blue rubber bleb nevus syndrome has to be considered in the differential diagnosis of chronic anemia or gastrointestinal bleeding. Patients should be investigated by endoscopy, which is the most reliable method for detecting these lesions. The patient underwent gastroscopy and enteroscopy via enterotomy with identification of all lesions. Minimal resection of the larger lesions and string-purse suture of the smaller ones involving all the layers of the intestine were performed. The string-purse suture of the lesions detected by enteroscopy proved to be an effective technique for handling these lesions, avoiding extensive intestinal resection and stopping the bleeding. Effective management of these patients demands aggressive treatment and should be initiated as soon as possible to avoid risks involved in blood transfusions, as occurred in this case.

RESUMEN

A dor pos-operatoria (PO) e aspecto relevante nos doentes que sao submetidos a hemorroidectomia. Variadas medidas sao propostas para reduzi-la. Alguns destes doentes tambem tem indicacao para exame colonoscopico (colono). Constitui, entao, opcao pratica a associacao dos procedimentos. Alem da praticidade, o preparo do colon previo a colono retardaria a defecacao e assim ensejaria dor PO menos intensa como empiricamente constatado. Para examinar esta hipotese, foram analisados retrospectivamente os prontuarios de 54 doentes operados no Hospital Alemao Oswaldo Cruz por um mesmo cirurgiao (AHG) entre outubro de 1989 e maio de 1993...

RESUMEN

O condiloma acuminado é a doença sexualmente transmissível (DST) mais comum e sua incidência tem aumentado após o aparecimento da síndrome da imunideficiência adquirida. É causado pelo papilomavírus humano (HPV), podendo se apresentar como pequenas e múltiplas lesöes verrucóides, ou mais raramente como grandes, únicas e volumosas lesöes anais, sendo entäo denominado tumor de Buschke-Loewenstein, caso em que o tratamento é controverso com alto índice de recidiva. Os autores relatam a história de um paciente de 42 anos de idade, sexo masculino, branco, portador de condiloma perianal gigante recidivante que foi submetido a vários tratamentos (soluçäo de podofilina a 25 porcento, Bleomicina 1 porcento, operaçöes com ressecçäo e eletrocauterizaçäo e oxigenoterapia hiperbárica) sem sucesso. O paciente evoluiu com infecçäo perianal grave e presença de secreçäo local abundante, com dificuldade para evacuar, foi operado e feita ressecçäo da lesäo, sendo associada sigmoidostomia em alça. Como näo houve cura, e antes da indicaçäo da imputaçäo abdômino-perineal do reto iniciou-se tratamento com radioterapia. Foi administrado 4500 cGy (25 sessöes de 180 cGy cada) com equipamento de megavoltagem, culminando no desaparecimento da lesäo condilomatosa e consequente formaçäo de fibrose local. Näo ocorreu recidiva da lesäo anal, e também näo foi encontrado vírus na macrobiópsia realizada após 20 meses de seguimento ambulatorial. Este caso mostra que a radioterapia pode ser opçäo útil em casos excepcionais de lesöes condilomatosas extensas e recidivantes, antes de submeter o paciente a intervençäo radical com amputaçäo do reto e ânus

RESUMEN

A fascite necrotizante do períneo e regiäo escrotal é uma entidade rara, caracterizada por extensa necrose da pele e tecido celular subcutâneo, tendo sido descrita em 1883 por Jean Alfred Fournier. A hemorroidectomia, apesar de ser procedimento operatório que ocorre em regiäo contaminada por resíduos fecais, muito raramente evolui para complicaçöes sépticas graves e necrotizantes. Neste trabalho apresentamos um caso de gangrena de Fournier que ocorreu em um doente alcoólatra e desnutrido, submetido a hemorroidectomia Miligan-Morgan em unidade ambulatorial. O desbridamento cirúrgico associado à colostomia derivativa, à antibioticoterapia ampla e à oxigeniterapia hiperbárica foram fatores determinantes para o sucesso terapêutico. Neste artigo discutimos as principais causas ou fatores envolvidos na gênese do processo infeccioso necrotizante pós-hemorroidectomia, realçando a necessidade de diagnóstico e terapêutica precoces

RESUMEN

Resumo: No estadiamento dos pacientes com neoplasias do aparelho digestivo, a tomografia computadorizada (TC) apresenta acurácia elevada na identificação de implantes hepáticos secundários. Este fato auxilia no planejamento da conduta a ser aplicada a estes pacientes. Entretanto, naqueles casos em que através dos exames pré-operatórios se decida pela conduta cirúrgica, a ultra-sonografia intra-operatória (USIO) pode desempenhar papel importante. A USIO tem demonstrado ser de grande utilidade na avaliação das lesões hepáticas e, com o auxílio da palpação do fígado pela equipe cirúrgica, pode contribuir no esclarecimento da natureza de possíveis lesões hepáticas. Os autores relatam,de maneira original, a utilização de USIO no estudo de pequenos nódulos hipoatenuantes identificados por TC no pré-operatório de pacientes com adenocarcinoma colorretal e pancreático.
