Surgical Management for a Giant Hydatid Cyst of the Lung using Hugon Technique

Human echinococcosis is a zoonosis caused by Echinococcus Granulosis. It occurs in rural regions where sheep and goat farming is widespread like Algeria. It constitutes a real public health problem. The lung occupies the second location after liver. The managment of pulmonary hydatid cyst is essentially surgical. In giant and large pulmonary hydatid cysts, pulmonary resection is the usual method of surgical treatment. We report a case of a patient presenting with a giant hydatid cyst of the lung and treated surgically by Hugon technique which is a conservative technique and consists of enucleation of the cyst.

Bilateral Giant Hydatid Pulmonary Cysts in a Pediatric Patient: A Rare Case Report

Introduction Pulmonary hydatid cysts, resulting from the Echinococcus tapeworm larva, primarily affect the lungs. The global incidence is elevated in regions with prevalent livestock farming due to the ingestion of Echinococcus eggs. Bilateral involvement is an infrequent presentation, carrying inherent respiratory risks. Accurate and prompt diagnosis necessitates a comprehensive approach involving imaging studies and serological tests to uncover this parasitic affliction. Case presentation In a 15-year-old male from an underprivileged rural background, bilateral giant hydatid cysts manifested. The patient's exposure to this parasitic infection was linked to his rural setting and contact with pets. The case unfolded with respiratory symptoms, prompting an investigation that revealed substantial bilateral cystic lesions. Successful surgical intervention and diligent postoperative care resulted in a smooth and uncomplicated recovery for the patient. Conclusion While giant bilateral hydatid cyst cases are rare, their documentation provides invaluable insights into the understanding and management of this complex condition. The prognosis hinges on various factors, underlining the importance of a multidisciplinary post-surgical approach for optimal patient outcomes.

Giant hydatid cyst of the liver: a case report with literature review

Hydatid cyst is a parasitic infection most commonly localized in the liver. They may not be diagnosed early because they remain asymptomatic at small sizes and may reach large sizes at the time of diagnosis. In this situation, compression symptoms may occur and they may present with serious complications such as rupture and anaphylactic shock, which are rare. Treatment methods are determined by classification according to the imaging techniques used in the diagnosis. In the present case, echinococcal cysts originating from segments 5, 6, and 7 in the right lobe of the liver, reaching 35 cm in diameter, caused compression symptoms. The diagnosis was made by abdominal tomography showing characteristic daughter vesicles and calcified cystic wall. The patient underwent pericystectomy and had an uneventful postoperative course with no recurrence in the 5-year follow-up.

Percutaneous Treatment of Giant Hydatid Cysts and Cystobiliary Fistula Management

To investigate the efficacy and safety of percutaneous treatment in cystic echinococcosis (CE) type 1 and 3a giant cysts (with at least one diameter>10cm) according to the World Health Organization classification and to evaluate the management of complications, especially cystobiliary fistulas (CBFs). This retrospective study included 66 patients with 68 CE1 and CE3a giant cysts treated with percutaneous catheterization between January 2016 and December 2021. The characteristics of the cysts, major and minor complications, time to catheter removal, and length of hospital stay were recorded. Among the 68 cysts, CBFs occurred in 35 (51.5%), cavity infections in 11 (16.1%), recollection in five(7.4%), and anaphylaxis in three(4.5%). There was no mortality. Biliary drainage was observed intraoperatively in 20 (29.4%) and only postoperatively in 15 (22.1%) of the 35 cysts with CBFs. A plastic biliary stent was placed in 18 (51.5%) of the 35 cysts with CBFs. The patients with CBFs had a longer hospital stay and time to catheter removal than those without fistulas (15.3±10.9 vs. 6.1±2.6 days and 32.7±51.8 vs. 6.2±3.1 days, respectively; P<0.001). Of the patients who developed recollection, three were treated with secondary catheterization, and two underwent surgery. In total, three patients underwent surgery. The rate of clinical success was 95.4%. All cysts were followed up for an average of 19.1 (range, 12-60) months, and there was an average 88.8% reduction in cyst volume compared to the initial evaluation. CE1 and CE3a giant cysts can be treated effectively and safely with high clinical success using the catheterization technique. Contrary to what has previously been reported for these patients, the rate of CBFs is high, but these patients can successfully be treated with percutaneous drainage and/or endoscopic retrograde cholangiopancreatography without the requirement of surgery.

Parenchyma Preserving Surgery in Giant Hydatid Cyst of Lung: A Case Report

Cystic echinococcosis (CE) is parasitic infestation characterized by the development of cyst as a consequence of the parasitization of humans by the larval stages of cestode Echinococcus granulosus. We present a case of 66 years old man who presented with a history of dry cough, mild fever and occasional shortness of breath for 1 year, which was gradually progressive with no history of chest pain or weight loss. Chest x-ray revealed a well-circumscribed homogenous opacity in the right hemithorax. Computed tomography (CT) of the chest revealed a large cystic lesion 18× 15 × 14 cm in the right hemithorax involving the whole of the right lower lobe and causing compression atelectasis of the middle lobe. The patient underwent lung preserving surgery with cystectomy and capotionnage. The patient was discharged on the 6th postoperative with a good clinical and radiological outcome. This case report highlights that lung-preserving surgery can be performed in giant hydatid cysts with a good outcome.

Percutaneous treatment of giant hydatid cysts: a single-center experience of 58 cysts.

The aim of this study is to evaluate the efficacy of percutaneous treatment in hydatid cysts (HCs) with at least one diameter larger than 10cm. 58 CE1 or CE3a HCs with at least one diameter larger than 10cm which were treated with catheterization between September 2016 and December 2021 were retrospectively analyzed. Mean age was 40 ± 17.7 (18-80). Majority of HCs were in the liver (89.6%). Median follow-up was 28months. Technical success rate was 100%; however, a second procedure was needed in 13 cysts due to recollection (n = 4), infection (n = 6), and recurrence (n = 3). Giant HCs can be effectively treated with catheterization with low complication rates.

Giant hydatid cyst with multivisceral compromise. Extracorporeal circulation for major resection

Background: Echinococcosis is a zoonosis caused by the echinococcus microorganism, a parasite with 6 described species in literature, the main one in humans being echinococcus granulosus. Transmission in humans is via the fecal-oral route, with main hepatopulmonary involvement but with a high risk of systemic dissemination. Diagnosis is generally incidental, patients present a wide range of non-specific signs and symptoms, however, some of them are closely related to localization, size, and quantity of cysts. The latent risk of this infection is septic shock secondary to intraperitoneal rupture, which increases the risk of mortality. The gold standard of management involves anthelmintic therapy and radical surgical management.

Postoperative Recurrent Abscess in Pulmonary Hydatid Cyst

Cystic echinococcosis (CE) is a disease that is endemic in our country and occurs as a result of the contamination of the eggs of the parasite Echinococcus granulosus. The first preferred treatment method in lung involvement of CE is surgery. In our study, we aimed to present a patient with postoperative recurrent intrathoracic extraparenchymal abscess focus who was operated for giant hydatid cyst. A 21-year-old male patient was admitted to our clinic with the complaint of chest pain. In the radiological examinations of the patient, a recurrent 122*62 mm abscess was detected despite being drained twice. The patient underwent a thoracotomy, the abscess was drained, and omentoplasty was performed to prevent air leakage due to severe destruction of the lung parenchyma of the patient whose cyst pouch was left open in the first operation. There are different surgical procedures for pulmonary hydatid cysts, but the first choice should be cystotomy + capitonage because if the cyst pouch is left open, it can cause abscess, empyema and lung destruction.

P-110 SURGICAL MESH INFECTION SECONDARY TO SKIN NECROSIS MANAGED WITH NEGATIVE PRESSURE THERAPY IN A PATIENT UNDERGOING TAR (TRANSVERSUS ABDOMINIS MUSCLE RELEASE)

Abstract Aim To Show the management of skin necrosis, wound dehiscence and mesh infection in a patient undergoing TAR (Transversus Abdominis Muscle Release) through NPT (Negative Pressure Therapy) Material and Methods A 55-year-old man underwent elective surgery in 2017 for a giant hydatid cyst with portal rupture during the intervention, making a subcostal incision and subsequently midline laparotomy. Subsequently, he developed portal cavernomatosis and portal hypertension. In 2018, he underwent surgery for incisional hernia in a patient with a complex abdominal wall (extended subcostal incision + median laparotomy) performing a RIVES-type hernia repair. Develops chronic wall infection, mesh rejection and hernia recurrence that required reoperation with TAR (polypropylene mesh). One month after the intervention, he presents skin necrosis, wound infection and mesh infection in the upper third of the wound, which was managed through TPN cures for a year and a half. Results Given the dehiscence in the upper third of about 15×7 cm, conservative management was decided with cures and debridement of non-viable tissue. In contact with the polypropylene mesh, a silver dressing was applied, as well as treatment with negative pressure therapy. This cure was carried out for a year and a half every 3–4 days, being able to cover the mesh with granulation tissue and close it by secondary intention, thus avoiding a reintervention with mesh explant. Conclusions TPN is a useful tool in the management of mesh infections in patients with complex abdominal wall, thus avoiding reintervention and mesh explantation.

Respiratory Distress Due to Giant Pulmonary Hydatid Cyst

Pulmonary echinococcosis most frequently occurs in the right and both lower lobes. Children are more likely to develop pulmonary rather than hepatic echinococcal cysts. Some evidence suggests that echinococcal cysts develop more rapidly in the lungs of children than those of adults, which may explain the more common appearance of pulmonary cysts in children. Younger patients have larger cysts owing to their greater tissue elasticity. Large pulmonary hydatid cysts are critical because they pose a higher risk of rupture. Herein, we present an eight-year-old girl presented with severe respiratory distress due to giant hydatid cyst of right lung with shift of the mediastinum at left. The lesion displaced the trachea at left. The patient was successfully treated by parenchymal-saving operation. In conclusion, Giant hydatid lung cysts represent a distinct clinical entity most frequently encountered in children and adolescents with more serious symptoms. Although non-complicated giant hydatid cysts have a good prognosis regardless of their size and can be safely treated by parenchyma-preserving surgery.

Giant cardiac hydatid cysts: A case report

A 55-year-old woman presented recently with dyspnea. The clinical examination was normal. Enlargement of the mediastinum with cardiomegaly was noted on the chest x-ray. Echocardiography showed the existence of 3 giant cardiac cysts which compressed the heart whose cavities are barely visible. A thoracic scanner revealed a giant hydatid cyst measuring 11 cm between the sternum and the right atrium. Another giant hydatid cyst, measuring 10 cm, was posterior and inferior behind the right inferior pulmonary vein and extended towards the right pleura. A 3rd giant hydatid cyst, measuring 10 cm, appeared to penetrate the wall of the left ventricle. The surgery was performed under femoral cardiopulmonary bypass, which involved opening of the 3 cysts after aortic clamping and resecting the multiple cysts of different sizes and more than 40 vesicles and debris. The patient left the hospital 10 days after undergoing surgery and Albendazole treatment. An isolated cardiac hydatid cyst is rare, of incidental discovery or after cardiac signs of complications when it is of a giant size and/or multiple cysts are present.

Spleen-sparing excision of giant splenic hydatid cyst

Splenic echinococcosis is a rare disease even in endemic regions such as the Mediterranean. The organs most involved are the liver and the lungs. However, other organs can be affected, such as the spleen. To our knowledge, primary involvement of the spleen is very rare, and a few cases of splenic hydatidosis (SHD) isolated in children have been reported. Splenectomy used to be the reference treatment, but it is now being questioned, first by the current trend towards conservative surgery, especially for a benign pathology and by the knowledge of postoperative complications. We report a case of a giant hydatid cyst of the spleen that underwent conservative surgery in the department of pediatric surgery at HabibThameur Hospital in Tunis. A 9-year-old girl, without any notable pathological history, coming from a rural environment with notion of contact with animals, who consulted for isolated recurrent abdominal pain evolving since six months. The examination showed a soft, painless abdomen with amarked splenomegaly. In view of a pauci-symptomatic clinical picture, a negative hydatic serology, a chest X-ray without abnormalities and the results of the ultrasound and abdominal computed tomography, the diagnostic of epidermoid cyst of the spleen was the most likely, especially with the primary location. Intraoperative findings did not match epidermal cyst and hydatic cyst was suspected. The puncture of the cyst brought back a clear liquid “rock water”. The “PAIR” technique with pericystectomy and epiploplasty was performed. Anatomopathological examination confirmed the diagnosis. The postoperative course was uneventful. The diagnosis of splenic hydatidosis must be evoked ahead of any cyst of the spleen especially in endemic countries. The choice of surgical technique is controversial. In children, conservative surgery is always preferable and is currently recommended by most authors.

Discovery of a giant pulmonary hydatid cyst on thoracic deformation in a child.

A 9-year-old girl without notable history who presented with a right thoracic deformity in a context of apyrexia. On admission she was hemodynamically stable, not dyspneic with no notion of hemoptysis or hydatid vomiting. The right hemithorax was bulging on inspection (A) associated with a right fluid effusion syndrome. The radiograph showed: a right pleurisy of great abundance pushing back the trachea (B).The thoracic CT scan: a giant hydatid cyst measuring 20cm x 13cm of great axis of the middle and upper lobar associated with a reactive pleurisy (C,D). The resection of the protruding dome and the extraction of the proligeral membranes were carried out (E). Blinding of the fistulas was continued by padding. After the stay in intensive care, respiratory physiotherapy was started. The postoperative course was simple, the control X-ray showed the re-expansion of the lung at the wall (F).

Minimal invasive approach for Giant Pulmonary Hydatid cyst

Hydatid cyst is a major health problem in agricultural countries caused by larval stage of Echinococcus granulosus. Hydatid cysts of 10 cm or greater in diameter are called “giant” cysts and traditionally have been considered to be more difficult to treat surgically. A 30 year male presented with complaints of cough and chest pain for three days and a CECT chest suggesting lung abscess. When thoroughly evaluated with bedside ultrasound, it was revealed to be a case of giant Hydatid cyst. The patient underwent cystostomy with closure of bronchial opening with capitonnage with minimal invasive approach (VATS assisted minithoracotomy). Even Giant Hydatid cyst can be managed with VATS, avoiding formal thoracotomy. Preoperative sonoscopy can localize the exact site for port placement and guide the surgeons on the operation table.

Modified capitonnage technique for giant pulmonary hydatid cyst surgery.

This study investigated the effectiveness of the modified technique (Aydin Technique), which was applied for capitonnage in the surgical treatment of giant pulmonary hydatid cysts. Twenty-two cases were operated on for giant hydatid cysts with a total of 23 modified techniques for capitonnage (bilateral giant hydatid cyst in 1 case) in our clinic between January 2018 and December 2020. The demographic data were recorded. Thirteen out of 22 (59.1%) of cases were male and 9 (40.9%) were female. The mean age was 22.0 ± 15.8 and 14 cases (63.6%) were children. Hydatid cysts were intact in 13 (56.5%) cases and ruptured in 10 (43.5%) cases. Hydatid cyst diameters were on average 123 ± 21 mm. A modified method was performed for capitonnage in all cases while decortication was performed in 2 (8.7%) cases due to pleural thickening. Radiological atelectasis was observed in 6 cases (27.3%) postoperatively. The patients with atelectasis recovered without any clinical problem and no intervention was needed. In 1 case, an infection developed at the incision site. Postoperative prolonged air leak, empyema and mortality were not observed in any of the cases. The postoperative mean length of hospital stay was 7.18 ± 2.15 days. The mean follow-up period was 19.5 ± 11.5 months. No recurrence was encountered in the follow-up of the patients. The results of this study may suggest to perform this new-described modified Aydin technique to avoid major capitonnage complications of the giant pulmonary hydatid cyst surgery.
