Quiste hepático gigante complicado por rotura traumática / Giant Hepatic Cyst Complicated by Traumatic Rupture

Introducción: Quistes hepáticos son formaciones de contenido líquido-seroso rodeado de parénquima hepático normal y sin comunicación con la vía biliar intrahepática. Mayor incidencia en adultos mayores de 50 años, con una relación mujer / hombre de 1.5: 1. Son asintomáticos. Los síntomas se presentan debido a su tamaño o bien por la presencia de complicaciones como la hemorragia, la rotura, la infección intraquística, o la compresión de estructuras adyacentes. Objetivo: Caracterizar a una paciente que presenta quiste hepático gigante complicado por rotura traumática. Caso clínico: Paciente femenino de 81 años, acudió a emergencia luego de haber presentado caída impactándose sobre superficie dura a nivel de parrilla costal e hipocondrio derecho, presentó dolor abdominal intenso acompañado de nausea y vómito. Al examen físico mostró signos claros de irritación peritoneal. Se realizó tomografía axial computarizada que reporta rotura de la pared de quiste hepático y aproximadamente 600 ml de líquido libre en cavidad. Se efectúo tratamiento quirúrgico de emergencia al realizar destechamiento del quiste y lavado de la cavidad. Conclusiones: Los quistes hepáticos, debido a su tamaño o complicaciones pueden poner en peligro la vida de los pacientes. Es necesario que dentro del arsenal diagnóstico del cirujano esté presente el conocimiento de esta patología(AU)

Introduction: Hepatic cysts are formations with liquid-serous content surrounded by normal liver parenchyma and without communication with the intrahepatic bile duct. It is reported with higher incidence in adults over fifty years of age, with a women/men ratio of 1.5: 1. They are asymptomatic; symptoms appear due to either their size or the presence of complications such as hemorrhage, rupture, intracystic infection, or compression of adjacent structures. Objective: To characterize a patient with a giant hepatic cyst complicated by traumatic rupture. Clinical case: A 81-year-old female patient went to the emergency room after falling and subsequently impacting herself on a hard surface at the level of the rib cage and right hypochondrium; she presented intense abdominal pain accompanied by nausea and vomiting. The physical examination showed clear signs of peritoneal irritation. A computerized axial tomography was performed, reporting rupture of the hepatic cyst wall and approximately 600 mL of free fluid within the cavity. Emergency surgical treatment was performed after cyst unroofing and cavity washing. Conclusions: Hepatic cysts, due to their size or complications, can endanger the patients' lives. It is necessary for the surgeon to consider knowledge of this condition as part of his or her diagnostic resources(AU)

Managements of simple liver cysts: ablation therapy versus cyst unroofing

BACKGROUNDS/AIMS: Simple liver cysts were easily recognizable with the advanced imaging procedures, such as ultrasound and computed tomography scan. A large cyst or significant symptoms were indications for the treatments. Ablation therapy with sclerotic agents was effective, but there were several complications including severe pain. With the surgical cyst unroofing method introduced, we compared the cyst unroofing method and ablation therapy. METHODS: Between March 1997 and May 2011, we performed treatments of simple liver cysts in 27 patients. There were 23 women and 4 men (age range: 42-84 years; mean age: 64 years). The cyst unroofing was undergone with laparoscopic (n=13) and open technique (n=1). The ablation therapy was performed with ethanol (n=13) and acetic acid (n=1). RESULTS: The usual symptoms of the liver cysts were abdominal mass (n=7), indigestion (n=4), abdominal discomfort (n=3), and the increasing size of the cysts (n=4). The mean diameter of the cysts was 10.9 cm. The cyst unroofing method was performed effectively in 14 patients. One patient had bleeding during operation, and was converted to the open technique. One patient had a bile leak from the cyst, but it was successfully closed with the laparoscopic technique. Among the 14 cases with the ablation therapy, there were 4 complications: hematoma (n=1); cyst leaking during aspiration (n=2); acute renal failure (n=1); and death due to acetic acid intoxication (n=1). CONCLUSIONS: Laparoscopic cyst unroofing was more effective and safer in management than the ablation therapy in simple liver cysts.

Laparoscopic cyst unroofing in the treatment of ploycystic kidney: A report of 13 cases / 中国微创外科杂志

Objective To explore the operative approach, method,indication,and clinical feasibility of laparoscopic or retroperitoneoscopic treatment of ploycystic kidney.Methods The renal cyst unroofing(bilateral,9 cases;unilateral,4 cases) was performed under laparoscope(2 cases) or retroperitoneoscope(11 cases).The renal adipose capsule was dissected with a harmonic scalpel to fully visualize the whole kidney.According to preoperative positioning results,the cysts at all sizes were exposed.Then all visible cysts were unroofed or fenestrated with a margin 0.5 cm from the renal parenchyma.The cystic fluid was drawn out as much as possible.Results The operations were completed smoothly in the 13 cases.Pneumatothorax developed on the day of laparoscopic operation in 1 case,and then was cured by closed thoracic drainage.The operation time was 50～240 min(mean,139 min),and the blood loss was 10～200 ml(mean,58 ml).Patients began out-of-bed activities in 1～2 days after operation and were discharged from hospital at 3～10 days.The pathological findings were in accordance with changes of ploycystic kidney.Follow-up examinations were carried out for 1～30 months(mean,14.3 months).Back pain was relived in 8 out of 11 cases.In 3 patients with a high blood pressure,the systolic pressure was decreased by 16～19 mm Hg at 9 months after operation.Ten patients presented normal hepatic and renal functions,while the remaining 3 patients with preoperative increased creatinine levels of 194～301 ?mol/L had a drop by 20～40 ?mol/L.Conclusions Treatment of cyst unroofing under laparoscope or retroperitoneoscope is a safe and effective method in the treatment of ploycystic kidney,being worthy of clinical recommendation.
