Abscesos residuales en apendicitis aguda: comparación entre abordaje laparotómico vs. laparoscópico / Residual abscesses in acute appendicitis: comparison between laparotomy vs. laparoscopic / Abcessos residuais na apendicite aguda: comparação entre laparotômico vs. laparoscópico

La apendicitis aguda es la urgencia quirúrgica más frecuente con una incidencia de 1.17 pacientes/1,000 habitantes. Con el advenimiento de la laparoscopía, un nuevo enfoque mini invasivo surgió para el tratamiento de la apendicitis aguda. Se han demostrado algunas ventajas de este abordaje como menor dolor posoperatorio, incisiones más pequeñas, estadías hospitalarias más cortas y un rápido reintegro a las actividades diarias y laborales, con menor frecuencia de infecciones a nivel de la herida operatoria. Sin embargo, se ha asociado también con un aumento en la frecuencia de abscesos residuales intra-abdominales. En este trabajo analizamos de manera retrospectiva a todos los pacientes operados en el Hospital Maciel de Montevideo, a los que se les realizó una apendicectomía entre el 1° de Junio de 2013 y el 30 de junio de 2016, tanto por vía laparoscópica como laparotómica. Esto correspondió a un total de 426 pacientes. 235 (55%) eran hombres y 191 (45%) mujeres. La media de edad fue de 32,6 en un rango desde los 15 años hasta los 96 años de edad. 128 pacientes presentaban apendicitis edematosas (30%), 157 apendicitis flemonosa (36,9%) 76 pacientes apendicitis gangrenosas (17,8%) 37 pacientes absceso o plastrón (8,7%) y peritonitis en 28 pacientes (6,6%). Con respecto al abordaje, 287 se realizaron por vía laparoscópica (67,4%) y 139 se abordaron por vía laparotómica (32,6%). Los abscesos residuales representan el 3,28% del total, no habiendo diferencias significativas entre los diferentes abordajes. La gran mayoría de estos abscesos residuales pueden tratarse con antibioticoterapia exclusivamente. La tasa de conversión fue del 8,7%. No se observaron lesiones de víscera hueca con el abordaje laparoscópico en esta serie.

Acute appendicitis is the most frequent surgical emergency with an incidence of 17 patients/1,000 inhabitants. With the advent of laparoscopy, a new mini-invasive approach emerged for the treatment of acute appendicitis. Some advantages of this approach have been demonstrated, such as less postoperative pain, smaller incisions, shorter hospital stays and a rapid reintegration to daily and work activities, with a lower frequency of infections at the level of the operative wound. However, it has also been associated with an increase in the frequency of intra-abdominal residual abscesses. In this paper, we retrospectively analyzed all patients operated on at the Maciel Hospital in Montevideo, who underwent an appendectomy between June 1, 2013 and June 30, 2016, both laparoscopically and laparotomically. Of these 235 (55%) were men and 191 (45%) women. The average age was 32.6 in a range from 15 years to 96 years of age. 128 patients presented edematous appendicitis (30%), 157 phlegmonous appendicitis (36.9%), 76 patients gangrenous appendicitis (17.8%), 37 patients presented abscess or plastron (8.7%), and peritonitis had developed in 28 patients (6.6%). Regarding the approach, 287 were performed laparoscopically (67.4%) and 139 were approached via laparotomy (32.6%). The residual abscesses rate represents 3.28% of the series, with no significant differences in incidence between the two different approaches. The vast majority of these residual abscesses can be treated with antibiotic therapy alone. The conversion rate was 8.7%. No intestinal lesions were observed with the laparoscopic approach in this series.

A apendicite aguda é a emergência cirúrgica mais freqüente, com uma incidência de 17 pacientes/1.000 habitantes. Com o advento da laparoscopia, uma nova abordagem mini-invasiva surgiu para o tratamento da apendicite aguda. Isto têm demonstrado algumas vantagens, como menor dor pós-operatória, incisões menores, menor hospitalização e restabelecimento mais rápido as atividades diárias e ao trabalho, assim como infecções menos freqüentes ao nível da ferida cirúrgica. No entanto, também foi associado a um aumento na freqüência de abscessos residuais intra-abdominais. Foram analisados retrospectivamente todos os pacientes operados no Hospital Maciel de Montevidéu, submetidos a uma apendicectomia desde o dia 01 de Junho de 2013 a 30 de Junho de 2016, tanto por abordagem laparoscópica como laparotomica. Destes, 235 (55%) eram homens e 191 (45%) mulheres. A idade média foi de 32,6 com intervalo de 15 anos a 96 anos de idade. 128 pacientes apresentaram apendicite edematosa (30%), 157 apendicite flemonosa (36,9%) 76 pacientes apendicite gangrenosa (17,8%) 37 pacientes abscesso ou plastrão (8,7%) e peritonite em 28 pacientes (6,6% ) Quanto à abordagem, foram realizadas 287 apendicectomias por via laparoscópica (67,4%) e 139 foram abordadas por laparotomia (32,6%). Os abscessos residuais representam 3,28% do total, não havendo diferenças significativas entre as diferentes abordagens. A grande maioria desses abscessos residuais pode ser tratada apenas com antibioticoterapia. A taxa de conversão foi de 8,7% Nenhuma lesão visceral foi observada com a abordagem laparoscópica nesta série.

Current management of spontaneous intra-abdominal abscess in Crohn's disease / Tratamento atual de abscesso intra-abdominal espontâneo na doença de Crohn

ABSTRACT Crohn's disease (CD) is a chronic transmural disease process with approximately 10% of patients developing spontaneous intra-abdominal abscess during the first 5 years after the diagnosis. The symptoms are often nonspecific. The treatment modalities include the use of wide-spectrum antibiotics, imaging-guided percutaneous drainage (PD) and surgical drainage with or without resection. The best initial treatment strategy has not been settled controversial, as there are only retrospective studies with small sample sizes available in the literature. The majority of the patients would eventually need surgery. However a highly selected patient population with small abscess in the absence of fistulas or bowel strictures, especially those naive to immunomodulators or biologics, may respond to medical treatment alone with wide-spectrum antibiotics. The increased use of PD drainage in the last few years has been shown to reduce postoperative morbidities and risk of fecal diversion, allowing for subsequent elective surgery. Varied success rates of PD drainage have been reported in the literature. The initial surgical intervention of CD-related spontaneous abdominal sepsis is mandatory in patients with diffuse peritonitis due to free perforation. Surgery is also indicated in those with failed initial medical treatment and/or PD. This review article was aimed to evaluate the treatment modalities for spontaneous intra-abdominal abscess in CD patients and propose an algorithm for the best management of this complication.

RESUMO A doença de Crohn (DC) é um processo patológico transmural crônico, em que aproximadamente 10% dos pacientes desenvolvem um abscesso intra-abdominal espontâneo durante os primeiros 5 anos após o diagnóstico. Com frequência os sintomas são inespecíficos. As modalidades terapêuticas são o uso de antibióticos de amplo espectro, drenagem percutânea (DP) orientada por imagem, e drenagem cirúrgica com ou sem ressecção. A melhor estratégia terapêutica inicial ainda não ficou estabelecida e há controvérsias, visto que a literatura conta apenas com estudos retrospectivos com pequenas amostras. Em sua maioria, os pacientes acabarão necessitando de cirurgia. Mas uma população altamente selecionada de pacientes, com pequeno abscesso na ausência de fístulas ou constrições intestinais, especialmente aqueles que jamais foram medicados com imunomoduladores ou agentes biológicos, podem responder exclusivamente ao tratamento clínico com antibióticos de amplo espectro. Foi demonstrado que o uso mais frequente da DP nos últimos anos diminui as morbidades pós-operatórias e o risco de desvio fecal, o que possibilita uma subsequente cirurgia eletiva. Na literatura, têm sido relatados percentuais de sucesso variados com a DP. A intervenção cirúrgica inicial para a sepse abdominal espontânea relacionada à DC é obrigatória em pacientes com peritonite difusa, devido à perfuração livre. Também há indicação cirúrgica naqueles pacientes que não conseguiram obter sucesso com o tratamento clínico inicial e/ou DP. Esse artigo de revisão teve por objetivo avaliar as modalidades terapêuticas para o abscesso intra-abdominal espontâneo em pacientes com DC; além disso, propõe um algoritmo para o melhor tratamento dessa complicação.

Comparative study of three antimicrobial drugs protocol (Ceftriaxone, Gentamicin/Amikacin and Metronidazole) versus two antimicrobial drugs protocol (Ceftriaxone and Metronidazole) in cases of intra-abdominal sepsis.

BACKGROUND: Treatment of intra-abdominal sepsis with antibacterial drugs should be initiated as soon as possible diagnosis is made before surgery and continued in the post operative period, unless required to be changed (when there is no satisfactory clinical response). The ideal agent (s) and duration of therapy remains somewhat controversial. However, early experimental and subsequent clinical studies have indicated that the spectrum of chosen antibacterial activity must encompass both colonic aerobes and anaerobes including B. fragilis. There are a number of multi drug protocols that are used to treat intra-abdominal septic conditions. Empiric use of these protocols not only adds toxicity to already ill patient but therapy becomes costly and utilizes human resource, unnecessarily. AIM OF STUDY: To study the clinical efficacy of the treatment of intra-abdominal sepsis with protocol -A (Ceftriaxone, Metronidazole and aminoglycoside) versus protocol -B. (Ceftriaxone and Metronidazole). MATERIAL AND METHODS: This is a prospective randomized study conducted at NGMC, Nepalgunj, Nepal (2003-2004) on the patient attending for the treatment of intra-abdominal sepsis. Patients included in this study were of inflammation, obstruction with or without gangrene and perforation of appendix, small bowel and large bowel with localized or generalized peritonitis. These patients were managed surgically by- appendicectomy, closure of perforation, resection and anastomosis (R & A) and resection and proximal colostomy. Patients of large bowel obstruction without gangrene and small bowel gangrene were managed by R & A. These patients had significant faecal spillage at the surgical site as well as in the peritoneum. At the end of operation peritoneum and surgical site of all cases were washed with saline and povidone-iodine solution. They were put on one of the two protocols for post-operative treatment. A total 59 patients were included in this study. 32 cases were treated with protocol- A and rest 27 cases were treated with protocol- B. These cases were selected randomly for this study. Their outcome was compiled and compared under following headings: postoperative recovery, postoperative pyrexia, wound infection and dehiscence, anastomotic leak, residual abscess and cost of therapy. STATISTICAL ANALYSIS: Statistical analysis was done with the help of Chi square test. RESULT: Of the 59 patients, 32 were randomized to group I, 27 to group II. These groups were comparable in age, weight, sex and duration of therapy. Uneventful recovery was noted in 87.5 % (28/32) in -group I where as in 70.37% (19 /27) in-group II. Complications were observed in 12.5% in-group I where as 29.63 % in-group II. 10 patients in-group I where as 7 patients in -group II had surgical site infections (SSIs). All of these had superficial wound infection with/or without dehiscence of small portion of wound. A single case of residual abscess and anastomotic leak was observed. Postoperative pyrexia was noted in 8 patients in-group I where as in 6 patients in-group II. In pyrexia, temperature ranged from 99-104 0F. Finally except one case, rest of the cases recovered. On follow up after 3weeks, the cases recovered were doing well. CONCLUSION: At least three conclusions can be drawn from this study. Firstly protocol A is equally effective as protocol B. Secondly; it appears that combining aminoglycoside with Ceftriaxone therapeutically has no significant (P = 0.09) benefit over Ceftriaxone alone. Finally protocol A is less expensive in terms of total therapy than protocol B and can be used without fear even in subnormal functioning kidney.

Absceso pancreático tuberculosos como manifestación inicial del síndrome de inmunodeficiencia adquirida (SIDA) / Tuberculous pancreatic abscess as the initial feature of acquired immunodeficiency syndrome (AIDS)

Introducción. La tuberculosis es frecuentemente la forma de presentación de la infección por VIH, y se presenta incluso en pacientes que aún no presentan el SIDA. Sin embargo, la afección pancreática es inusual, y de ésta, la focal es aún mas rara. Reporte del caso. Presentamos el caso de un hombre de 49 años con antecedentes de 25 parejas heterosexuales y laparotomía exploradora tres años antes por lesión hepática por arma de fuego, en la que fue multitransfundido. Acudió con un cuadro de un año de evolución con fiebre de hasta 39ºC, diaforesis, pérdida de peso de 8 kg en ocho meses y dolor abdominal, a quien por ultrasonografía se detectó imagen compatible con absceso pancreático por lo que se sometió a laparotomía exploradora para drenaje del mismo; la biopsia reportó tuberculosis. Persistió con dolor abdominal y fiebre, y la tomografía computada de abdomen mostró persistencia del absceso. La determinación de anticuerpos contra VIH fue positiva, con una cuenta de CD4 de 110/mm3. Se inició tratamiento antifímico con mejoría clínica y tomográfica. Tras dos años de seguimiento, el paciente se encuentra estable, únicamente en tratamiento antirretroviral con triple esquema, sin datos de recurrencia de la infección por tuberculosis. Discusión. La afección pancreática focal es una complicación muy infrecuente de la tuberculosis. Se considera que resulta de la diseminación de la infección de los ganglios linfáticos contiguos. Cuando se efectúa la aspiración con aguja de un absceso pancreático es necesaria la realización de cultivo para diagnóstico de tuberculosis. El tratamiento actualmente indicado es a base de un esquema reforzado con cuatro antifímicos en la fase intensiva (rifampicina, isoniacida, pirazinamida y etambutol) y tres en la de sostén (rifampicina, isoniacida y etambutol). Se trata del primer caso reportado en México de absceso tuberculoso de páncreas

Intraperitoneal abscess in a new born secondary to Klebsiella septicaemia--a case report.

A five day old female baby was admitted with distension of abdomen since birth and nonbilious vomiting, fever of one day duration. Blood culture grew Klebsiella pneumoniae. Abdominal exploration revealed thick walled cavity containing purulent fluid grew klebsiella pneumoniae which was sensitive to various antibiotics including gentamycin. The child was treated with injection gentamycin and ceftazidime. The child had uneventful recovery and is doing well 3 years post operatively.
