Apendicitis subhepática con absceso subdiafragmático en paciente pediátrico sin malrotación intestinal: informe de un caso / Subhepatic appendicitis with subdiaphragmatic abscess in a pediatric patient without intestinal malrotation: case report

Introducción: Los cuadros de apendicitis aguda subhepática en niños son raros y no siempre se acompañan de malrotación intestinal, lo que dificulta el diagnóstico y manejo temprano. Caso clínico: Niño de 10 años de edad, con padecimiento de cinco días de evolución caracterizado por evacuaciones diarreicas, tratado con antibióticos. Posteriormente presentó vómito, dolor abdominal tipo cólico y fiebre de 39 °C. El abdomen se encontró blando y depresible, con escaso dolor en flanco derecho. El ultrasonido y la tomografía mostraron imagen compatible con absceso subdiafragmático. Se manejó con drenaje externo. Al no obtener respuesta se realizó laparotomía exploradora, encontrando apéndice inflamada, de 10 cm de longitud, en posición ascendente sobre la corredera parietocólica derecha y perforación del extremo distal a nivel subhepático. El paciente evolucionó con sepsis abdominal y choque séptico, requiriendo nueva intervención quirúrgica para drenaje de líquido serohemático. A los 40 días el paciente fue dado de alta. Conclusiones: La consideración anatómica del apéndice es importante, por las múltiples presentaciones clínicas, de las cuales 30 % son atípicas y el diagnóstico se enmascara ocasionando complicaciones como perforación y abscesos. Los casos de apendicitis aguda de localización subhepática son raros y por lo general se asocian a malrotación del intestino. El retraso del tratamiento relacionado con el cuadro atípico, ocasionado por la posición poco habitual del apéndice, implica estancia hospitalaria más prolongada y riesgo de incrementar la morbilidad y mortalidad.

BACKGROUND: Acute subhepatic appendicitis in children is an uncommon presentation. It is usually associated with intestinal malrotation. When these conditions are met, accurate diagnosis and early management decisions are delayed. CLINICAL CASE: We present the case of a 10-year-old male who had diarrhea without mucus or blood for 5 days. He was treated with antibiotics. Afterwards, he presented with vomiting, abdominal pain, and fever. Physical examination of the abdomen demonstrated a soft and depressible mass and pain in the lower right abdomen. Abdominal ultrasound and tomography reported image of subdiaphragmatic abscess. Percutaneous puncture and drainage were performed without results. Exploratory laparotomy was then performed, revealing a subhepatic perforation of the appendix. The patient evolved with abdominal sepsis and septic shock, resulting in a new surgical intervention for drainage of serohematic fluid. The patient improved and was discharged on day 40. DISCUSSION: It is very important to consider the position of the anatomic appendix during appendicitis because it contributes to the various clinical symptoms, of which 30% are atypical. Diagnosis is masked, leading to complications such as perforations and/or abscesses that extend the hospital stay. CONCLUSIONS: Acute subhepatic appendicitis in children is an uncommon presentation. It is usually associated with intestinal malrotation. Delay in treatment due to atypical symptoms caused by the abnormal position of the appendix conditioned complications that implied a prolonged hospital stay, with the risk of increasing morbidity and mortality of the patient.

Draining of subphrenic abscess into pericardial cavity - an incidental finding

The direct extension of a subphrenic abscess into the pericardial cavity is a rare finding. We report a 13 year old boy with Past History of Abdominal surgeries presenting with Right Upper quadrant pain, fever, chest pain and shortness of breath. An abdominal USG diagnosed a subphrenic abscess and an EGG demonstrated diffuse ST and T wave changes depictive of Acute Pericarditis. Echo guided drainage of thick pus from the pericardial cavity was performed which followed USG guided drainage of subphrenic abscess and finally Exploratory Laparotomy and drainage of subphrenic abscess + Mediastonotmy and Pericardiostomy + diaphragmatic repair was performed

A Case of Subphrenic Abscess with Ileal Fistula Caused by Metastatic Adenocarcinoma of Unknown Origin / 대한소화기학회지

Usual sources of subphrenic abscess with intestinal fistula are previous abdominal operation, inflammatory bowel disease and malignancy. Reported cases of intestinal fistula caused by adenocarcinoma were complicated by direct invasion. In this report, a 70-year-old male had a subphrenic abscess with intestinal fistula and the cause was a metastatic adenocarcinoma of unknown origin. As far as we know, this has not been reported previously in the literatures. The abscess went on chronic course for six months because intermittent administration of antibiotics modified its clinical presentation. The fistulous tract between the abscess and ileum was demonstrated by tubogram via the drainage catheter in abscess. The patient underwent surgical treatment because the cause of fistula was obscure. Invasion of the ileum by metastatic adenocarcinoma was diagnosed by the histologic examination of surgical specimen. Therefore, when a fistula develops without any apparent cause, there is a possibility of malignancy, and surgical approach must be considered. An early surgical approach will prevent the delay in treatment and reduce the mortality.

Perforated Meckel's diverticulum presenting as subphrenic abscess.

Meckel's diverticulum is known to present with myriad complications. However, its perforation followed by development of subphrenic abscess has not been reported in literature. We report this complication in an eleven-month-old child.

Orientaçäo atual em abscessos subfrênicos: contribuiçäo clínica / Up-to-date orientation in subphrenic abscesses: clinical contribution

Os traumatismos e as agressöes cirúrgicas abdominais representam, pelo menos na experiência dos autores, as causas que levam mais freqüentemente à formaçäo de abscessos na cavidade peritoneal. Näo obstante os progressos da antibioticoterapia e das técnicas de assepsia, a sua freqüência torna-se alvo de interesse. A presença de febre e leucocitose no pós-operatório ou em paciente politraumatizado devem sempre fazer suspeitar do aparecimento de tal complicaçäo. Um tratamento precose e adequado torna-se fundamental para eliminar o estado tóxico que a coleçäo purulenta produz e permitir a sobrevida do paciente

Postoperative subphrenic abcess. A study of 20 cases

20 post operative subphrenic abcess are repported, 11 secondary to hepatic hydatic cyst procedures [55%], 7 secondary to biliary surgery, one after splenectomy and one after digestive fistula after gastrectomy. The value of clinical signs, radiology and echotomography is emphasized. The mortality rate [10%] is the consequence of a septic state. The prevention should include a better surgical technique and an efficient drainage after various abdominal interventions
