MANAGEMENT OF COMPLICATED HYDATID CYST OF THE THORAX

Complicated hydatid cyst of the thorax is important to the clinical approaches and treatment methods in hydatid disease. The aim of this study was to evaluate the problems of complicated pulmonary hydatid cyst, including choice of surgical methods, diagnostic clues and to discuss the inherent risks of medical therapy and the delay of surgical treatment in pulmonary hydatid disease. Between 2002 and 2006, 40 operations were carried out in 37 patients whose diagnoses were complicated hydatid cyst. The surgical approach was a posterolateral thoracotomy in all patients; a phrenotomy in two patients and a thoracoabdominal approach in one patient and two-stage bilateral thoracotomy in four patients. The preferred surgical treatment procedure was cystotomy and modified capitonnage, which was carried out in 26 patients (70%). Other procedures included a cystotomy in five (14%) and decortication in six (16%) patients. Segmentectomy was carried out in 1 (3%), and wedge resection in four patients (11%). In 25 patients (67.5%), there were single hydatid cysts; whereas 12 patients (32.5%) had multiple cysts. Eleven patients had preoperative hydatid cyst history. Iatrogenic rupture of an intact hydatid cyst occurred in three patients. Extrathoracic involvement was apparent in 10 patients (27%). Intrathoracic but extrapulmonary involvement was apparent in six patients (16%). The morbidity ratio was 5%; there was prolonged air leak and atelectasis in one patient each. The mortality ratio was 3% (one patient). The average hospitalization duration for all patients was 5.7 days (range, 3-17 days). The mean follow up was 18.4 months with no recurrence. Complicated hydatid cyst may have different clinical manifestations and may present radiologically as a primary lung tumour. In patients with suspicious lung masses owing to endemic area, history of a hydatid cyst or contralateral or extrathoracic hydatid cyst involvement at the same time should indicate a complicated pulmonary hydatid cyst. Preoperative anthelmintic therapy must be avoided owing to the risk of perforation. Treatment of a complicated hydatid cyst differs from that of an intact hydatid cyst. Anatomic resection may be necessary owing to destroyed lung tissue secondary to suppuration from a hydatid cyst; however, parenchymal preserving surgery is preferable in an uncomplicated hydatid cyst. A modified capitonnage method is recommended for complicated hydatid cyst treatment as it has a low morbidity rate.

Role of endoscopic intervention in biliary complications of hepatic hydatid cyst disease

Objective. Biliary complications of hepatic hydatidosis are often difficult to detect and manage. The aim of this study was to present our experience on the effectiveness of endoscopic treatment modalities in cases of biliary complications of hepatic hydatid cysts. Material and methods. Over the past 10 years, 15 patients diagnosed with hepatic hydatidosis and manifesting symptoms and signs indicative of biliary involvement were examined by means of endoscopic retrograde cholangiopancreatography (ERCP) in our Gastroenterology Endoscopic Unit; 7 patients had already been operated on for hepatic hydatid cysts; one of them had a concomitant hydatid cyst in the lung. Diagnosis of the disease was based on a combination of ultrasonography (US), computed tomography (CT) and specific immunologic and/or microbiologic studies. Results. Biliary complications of hydatid cysts were detected by ERCP in 9 patients (60%). Eight (88.9%) patients displayed a communication between the hydatid cyst or its residual cavity and the biliary tree; 5 patients had daughter cysts or residual hydatid material within the biliary tree, 1 patient had a biliocutaneous fistula, 1 patient a postoperative biliary leakage and 1 patient had only an opacification of the hydatid cyst during ERCP. In one patient, ERCP showed stenoses of both of the main hepatic ducts due to their compression by the cyst. Jaundice (88.9%), fever (33.3%) and right upper quadrant abdominal pain (88.9%) were the most frequent manifestations. These complications were demonstrated by US and CT imaging in only 25% of the cases. Four patients underwent ERCP before surgery and 5 after surgery. Endoscopic management was successful in all patients, resulting in clearance of the biliary tree, closure of fistulas, stopping of biliary leakage and jaundice remission. No serious endoscopy-related complications were recorded, with the exception of a pulmonary hydatid cyst rupture during ERCP. Conclusions. This study suggests that endoscopic treatment modalities are helpful and safe methods in the treatment of biliary complications of hepatic hydatidosis before and after definitive surgical management of the hydatid cysts.

Kyste hydatique du poumon ouvert dans les bronches : apport de la tomodensitometrie

Purpose To describe the CT findings of ruptured pulmonary hydatid cyst (HC) and to establish a progressive CT staging. Patients and methods CT scans of 41 patients with pulmonary hydatid cyst complicated by rupture in the bronchi were retrospectively reviewed. We also reviewed the findings in the literature on the rupture of pulmonary hydatid cysts and the Lewall and McCorkell classification and proposed a more detailed staging related to the progression of HC. The Lewall and McCorkell communicating rupture is manifested by a tear of the endocyst with a discharge of the cyst's contents via the bronchioles that were incorporated in the pericyst: – Stage I: signet ring sign; – Stage II: crescent sign and inverse crescent sign; – Stage III: air bubble sign and honeycomb; – –Stage IV: air-water level, double arch sign, water lily sign, serpiginous aspect, regular air-water level; – Stage V: dry cyst sign, ball of wool aspect, small bell image, pseudotumoral aspect; – Stage VI: sequela image, residual cavity, and cicatricial image. Results Seventy-three complicated pulmonary hydatid cysts were included in the analysis and were distributed as follows: stage I (16%), stage II (12.7%), stage III (42.8%), stage IV, double arch sign (2.7%), water lily sign (10%), serpiginous aspect (8.2%), regular air-water level (5.4%), stage V, ball of wool aspect (6.8%), small bell image (15%), pseudotumoral aspect (4%), stage VI, residual cavity (4%) and cicatricial image (2.7%). Conclusion Our staging offers more details than the Lewall and McCorkell general classification. Moreover, this staging takes into consideration both the natural evolution of the HC and the particularities of the pulmonary location.

Management of Hepatic and Intracardiac Echinococcal Cysts: Case Report and Review of the Literature

Infection with Echinococcus granulosus affects the liver commonly, but disseminated involvement is rare. We describe a 63 year-old man with echinococcal infection producing both hepatic and cardiac involvement that was managed surgically after failed percutaneous hepatic treatment. This report is a case study of a unique surgical problem. Various treatment modalities are reviewed. The patient was a 63 year-old man from Iraq who immigrated to the United States after becoming infected with Echinococcus granulosus. He had undergone percutaneous management and albendazole therapy prior to presentation for treatment of hepatic hydatid cysts. He continued to have abdominal pain and fever and was referred to our institution. Imaging revealed persistence of the hepatic hydatid cysts, as well as a new finding of an intracardiac hydatid cyst. The patient underwent successful treatment of his complicated hepatic hydatid cysts with pericystectomy and repair of a biliary fistula. The cardiac cyst was removed as well. The patient made an uneventful recovery, and his symptoms resolved. Although rare, echinococcal infection may be encountered in the United States as travel increases to and from regions of the world where the disease is endemic. It is important for surgeons to be familiar with the multiple options for treatment of hydatid disease.

Surgical management and long-term outcome of complicated liver hydatid cysts caused by Echinococcus granulosus

The aim of this retrospective study was to evaluate clinical presentation and long-term outcome of patients treated surgically for complicated liver hydatid cysts. Eighty-four patients with liver hydatid cysts underwent an operation at the Geneva University Hospital between 1980 and 1999. Clinical presentation, postoperative morbidity, mortality, and long-term recurrence rate were evaluated. Among the 84 patients with liver hydatid disease, 35 patients (41%) presented complicated cysts (ie, cysts that had developed a fistula into adjacent structures or organs). In most patients, the fistula communicated with the biliary tree (n = 25), but we also observed communication with the right lung (n = 3), the right diaphragm (n = 2), liver parenchyma (n = 1), and peritoneal cavity (n = 1). Complete removal of the cystic disease was possible in 24 of 35 patients (70%). In 11 patients, fragments of cysts were not removed because of their location adjacent to main vessels. Postoperatively, 8 patients (23%) developed a severe complication (grade II and III). There were no postoperative deaths, and no recurrences of hydatid disease were observed with a median follow-up of 8.6 years (complete follow-up was obtained in 69% of patients). Complicated liver hydatid disease is frequent and was observed in almost half of patients operated for liver hydatid cysts at our center. Using a surgical strategy aimed at complete removal of cystic and pericystic tissue with simultaneous treatment of the fistulous tract, we observed 23% postoperative morbidity, no mortality, and no recurrence of disease with a median follow-up of >8 years.

Complicated hydatid cysts of the lung: clinical and therapeutic issues

Background The clinical presentation and the preoperative and postoperative complications associated with pulmonary hydatid cysts depend on whether the cyst is intact or ruptured. The aim of this study was to review the problems encountered in treating ruptured pulmonary hydatid cysts and to highlight the risks associated with chemotherapy and the delay of surgical treatment in pulmonary hydatid disease. Methods The medical records for 67 patients of pulmonary hydatidosis were retrospectively investigated. The patients were divided into two groups based on whether the pulmonary cyst was intact (group 1, n = 34) or complicated (group 2, n = 33). A complicated cyst was defined as one that had ruptured into a bronchus or into the pleural cavity. All patients were treated surgically. Data related to symptoms, preoperative complications, surgical procedures performed, postoperative morbidity, hospitalization time, and cyst recurrence were collected from each individual's records, and the group findings were compared. Results In most cases of intact pulmonary hydatid cysts, the lesions were either incidental findings or the patient had presented with cough, dyspnea and chest pain. In addition to these symptoms, the patients with complicated cyst had presented with problems such as expectoration of cystic contents, repetitive hemoptysis, productive sputum, and fever. The differences between the groups with respect to the rates of preoperative complications and postoperative morbidity, frequency of decortication, and hospital stay were statistically significant ( p < 0.05). Conclusions Surgery is the primary mode of treatment for patients with pulmonary hydatid disease. Complicated cases have higher rates of preoperative and postoperative complications and require longer hospitalization time and more extensive surgical procedures than uncomplicated cases. This underlines the need for immediate surgery in any patient who is diagnosed with pulmonary hydatidosis.

Pitfalls in the diagnosis of complicated pulmonary hydatid disease

The aim of this study was to present the pitfalls in the diagnosis of complicated pulmonary hydatid disease and to discuss the unusual radiological presentations of this endemic disorder in Turkey.We retrospectively evaluated 34 patients (12 females) aged between 8 and 64 years, who were operated on at our centre between 1991 and 1998 and diagnosed with complicated pulmonary hydatid cyst histopathologically. Computerized tomography (CT) scans of these patients were reviewed double-blind by two radiologists. The patients were then divided into two groups: group 1: initial radiological impression is pulmonary hydatid cyst and group 2: initial radiological impression is not pulmonary hydatid disease. These two groups were evaluated in terms of symptoms, radiographical presentation and laboratory tests.The presence of cystic appearance, water-lily sign, ring enhancement concomitant with intact cysts unanimously led the radiologists to the diagnosis of complicated pulmonary hydatid cyst, whereas solid appearance and presence of bronchial obliteration made the diagnosis unlikely. In such circumstances patient history, laboratory findings and bronchoscopic evaluation helped the diagnosis.In conclusion, in endemic regions like Turkey, atypical radiological presentation of complicated pulmonary hydatid disease should be considered in the differential diagnosis of solid pulmonary lesions.

Review of Cases with Cystic Hydatid Lung Disease in a Tertiary Referral Hospital Located in an Endemic Region: A 10 Years’ Experience

Background: Echinococcus disease is endemic in sheep-and cattle-raising areas world wide. Its prevalence is also high in the Mediterranean region including Turkey. Objective: To determine the presentation, approach to surgical treatment and outcome of hydatid disease in an endemic region. Methods: From January 1989 to December 1998 288 patients, aged between 1 and 71 years with a mean age of 31 years (134 female, 154 male), were operated on for pulmonary hydatidosis. Clinical charts of the patients were reviewed retrospectively in a tertiary referral hospital. Results: Of 288 patients, 30 patients were asymptomatic, the rest (89%) were symptomatic, cough and chest pain being the most common symptoms. Fifty-three patients (18%) had associated liver hydatid cysts. Bilateral lung hydatid cysts were present in 18 patients (6%). Recurrent hydatid cysts were observed in 33 patients (11%). Seventy-seven patients (27%) presented with complicated hydatid cysts. Postoperative morbidity was observed in 3 patients [bronchopleural fistula (2), infection of the cyst space (1)] and postoperative mortality in 1 patient who presented with hydatid lung disease associated with liver and brain cysts. In the remaining 98.6%, no complications were noted. Conclusions: In conclusion, hydatidosis is still an important public health problem in Turkey and in an endemic country such as Turkey hydatid lung disease should be considered initially in a patient presenting with a corresponding chest roentgenogram and a compatible epidemiologic history. Surgery is indicated in all symptomatic and/or enlarging or infected cysts. When necessary lobectomy or wedge resection can be the procedure of choice. Single-stage combined resection is preferred in hydatid lung disease with associated liver hydatid cysts. Total postoperative complication and mortality rate is low and we recommend a close follow-up of the operated cases to diagnose postoperative recurrence early in its course.

Free Hydatid Cyst only Covered with Germinative Membrane Disrupted from Fibrotic Capsule in the Peritoneal Cavity : a Case Report

Echinococcosis an endemic disease on the Asian continent, is caused by ecinococcus granulosus and rarely ecinococcus alveolaris. Although it occurs frequently in the liver and the lung, it can be localized in all tissues and organs. The purpose of this study is to report a rare localization and the complication of hydatid cyst in the pelvis: it pushed forward and upward the urine bladder and there was bilateral hydroureteronephrosis causing uraemia because of outflow obstruction. To our knowledge, a similar case has not been published before in English literature.

Endoscopic Retrograde Cholangiopancreatography (ERCP) in the Diagnosis of Biliary and Pancreatic Duct Disease: a Prospective Study on 668 Jordanian Patients

Endoscopic retrograde cholangiopancreatography (ERCP) is the method of choice in establishing the nature and the site of common bile and pancreatic duct disease and related complications. It was used in 668 Jordanian patients who presented with biliary or pancreatic disease and unexplained upper abdominal pain. Common bile duct (CBD) stones, postsurgical traumatic CBD strictures, papillary stenosis and malignant strictures were the most common findings in this study. The incidence of malignant strictures was less and the postsurgical CBD injuries, mainly CBD complete ligation, were more than what was reported by others. This procedure was also valuable in the investigation of unexplained upper abdominal pain and pancreatic disease.

Intrabiliary and Intraperitoneal Rupture of Hydatid Cyst: Report of Two Cases and Review of the Literature

Intrabiliary and Intraperitoneal Rupture of Hydatid Cyst: Report of Two Cases and Review of the Literature

Endoscopic retrograde cholangiography and sphincterotomy for complicated hepatic hydatid cyst.

We report on the results of 20 endoscopic cholangiographies indicated for hepatic hydatid disease: 14 for pre-operative investigation and 6 for post-surgical complications. In 4 out of 14 cases, endoscopic retrograde cholangiography (ERC) was not an effective procedure for the pre-operative diagnosis of complicated hepatic hydatid cyst in the biliary tract. Endoscopic sphincterotomy was performed without complications in 9 patients and permitted pre- or post-surgical removal of intrabiliary hydatid fragments in 6, successful treatments of 2 post-surgical external biliary fistulae and in association with transhepatic drainage, improvement of the clinical and biological course of one case of secondary sclerosing cholangitis. Endoscopic sphincterotomy might be indicated not only in the case of ERC diagnosis of complicated hepatic hydatic cyst, but also in the case of isolated cholangitis in patients with hepatic hydatid disease, and for complications of surgical treatment.

Surgical management of complicated hydatid cysts of the liver.

The most significant complications of hydatid cyst of the liver are rupture and suppuration with an incidence of 6-19%. Rupture into the biliary tract was the most frequent complication and comprised 170 out of 222 complicated hydatid cysts of the liver in the author's series. These jaundiced patients were managed both by obliteration of the residual cavity and restoration of the patency of the biliary tract which was obstructed by daughter cysts of remnants of the laminated membrane. Rupture into the bronchi requires immediate treatment due to bronchopulmonary complications which might ensue. Rupture into blood vessels and into the free peritoneal cavity is accompanied by severe anaphylactic shock which does not readily respond to corticosteroids. The former complication is accompanied by a high mortality rate, while the postoperative mortality of patients experiencing anaphylactic shock amounts to 1.8%.

Serious complications of hydatid cyst of the lung.

Hydatid disease is still very prevalent in Iraq both in humans and in animals. The middle and southern parts of the country are considered to be persistently endemic areas with a relatively high infestation rate (1, 2). Hydatid cyst could affect all ages and both sexes. No organ or tissue is spared. The cyst has been found in the brain, spinal cord, bones, kidneys, spleen, eyes, and heart. The liver is the highest and the lung is rated second as the sites most frequently affected. Hydatid cysts of the lung constituted about 25 to 33 per cent of all cases of hydatid. In one of the chest service units a total of about 115,000 persons with or without respiratory symptoms were reported to have had chest roentgenograms taken from 1960 to 1965. A shadow highly suspicious of hydatid cyst was found in approximately one in 100 cases. Operations were performed in 31 per cent of those patients, and the presence of hydatid cyst was verified (table 1) . In three major hospitals in Baghdad approximately 100 patients are operated upon annually for hydatid of the lung, and at least three times that number are reported but not operated upon, either because of bed shortage or the patient's reluctance. Hydatid cyst of the lung is not always a benign process. It is often symptomatic and produces a good deal of morbidity. Serious complications and death may occur. During the last six years some serious complications occurred at the Republic Hospital, and it is the writer's hope that drawing attention to these occurrences may ultimately lead to their reduction or prevention. The complications witnessed and studied are described in the following cases.
