Thoracoscopic treatment of pulmonary hydatid cyst in a child

Hydatid disease has a wide geographic distribution around the world. In human, the lungs are the second most commonly affected sites. Pulmonary hydatidosis is much more frequently encountered in children than in adults. Surgical treatment has remained the standard option in the management of hydatid disease. However, surgeons were able to replicate the principles of conventional surgery using minimally invasive techniques. Herein, we report a case of pulmonary hydatid cyst in a 9-year-old girl treated successfully using the thoracoscopic approach.     

The problems and advantages of one lung ventilation during surgical intervention in pulmonary hydatid cyst disease

Background Hydatid disease is the most severe helminthic zoonosis, with an important public health problem especially in rural areas in Turkey. The aim of this study was to review the problems and advantages encountered in surgical treatment of 43 patients who were ventilated with one-lung ventilation during last four years. Methods Patients, operated with one-lung ventilation, constitute the study group. Data related to symptoms, radiographic findings, performed surgical procedures, perioperative and postoperative morbidity, hospitalization time, and cyst recurrence were collected from each individual's records. Results Cystotomy and capitonnage were performed in all cases. Perioperative complications were seen in 5 patients. Four of these 5 patients had double-lumen endotracheal tube malpositioning. In one patient hypoxemia developed. The most common postoperative complication was atelectasis. One patient had recurrent cysts. There was no perioperative or postoperative death. Conclusions We prefer cystotomy and capitonnage because it is a fast and effective technique with limited postoperative complications. One-lung ventilation prevents the exposure of lower lung areas from massive aspiration, which may cause acute obstruction of airways, and contamination by cyst contents from the operative part of the lung that causes recurrent disease. One-lung ventilation in pulmonary hydatid cyst surgery may be preferred owing to lower mortality and morbidity rates.     

Mediastinal calcified hydatid cyst

Abstract

Mediastinal hydatid cyst is a rare disease and should be considered in differential diagnosis of mediastinal cystic lesions especially in endemic regions. This localization is very serious because of the surrounding vital structures. Surgery must be indicated immediately using conservative techniques without extensive resection when progression of dissection is difficult or dangerous. Medical treatment is necessary to prevent recurrence.     

An analysis of clinical features of pulmonary giant hydatid cyst in adult population

Background

We performed an analysis of giant hydatid cysts (GCHs) detected in the adult population by comparison with the features of other simple hydatid cysts (CHs) in the light of the relevant literature.

Methods

The records of 74 adult patients who were operated on in our clinic for pulmonary CHs between 2001 and 2005 were retrospectively evaluated. Cysts that were 10 cm or larger in diameter on any plane were considered GCHs. The cysts were classified into 2 groups as GCHs (group A) and other (group B). The groups were then compared for age, sex, symptom, cyst location, preoperative complications, surgical procedure performed, operative morbidity, and mortality.

Results

Of 74 patients, 10 (13.5%) were in group A and 64 were in group B. No differences were detected between the clinical presentation, gender distribution, surgical procedure performed, and postoperative morbidity and mortality rates of GCHs and other cysts in adults. In both groups, there were no significant differences between the rates of involvement of 2 lungs (P = .527). However, both groups had lower lobe involvement, more markedly in group A (81.8% and 45.5% respectively; P = .023). Two patients in group A (20%) and 18 patients in group B (28.1%) had complicated cysts.

Conclusions

The tendency of GCH to involve the lower lobe of the lung compared to smaller cysts suggests underlying mechanisms other than lung elasticity in the late onset of the symptoms parallel to cyst growth.     

A rare combination of hepatic and pericardial hydatid cyst and review of literature

Hydatid disease in human beings, as in all intermediate hosts, manifest as hydatid cyst (HC). It is an important cyclozoonotic disease, endemic in various sheep and cattle raising areas of the world, including India. The tapeworm commonly involved is Echinococcus granulosus. HC can occur almost anywhere in the body, most common organs being liver and lungs, and are usually solitary. In 25% of cases combination of liver HC with HC in other extra pulmonary locations are found. Cardiac HCs comprise of 0.5–2% of all HC cases. Within the heart, HCs are usually situated in the left or right ventricle and rarely found in the peri-cardium. Pericardial HC does not produce symptoms and is often painless and silent, until the cysts grow to a large size over the years, when the usual complications develop, such as cyst rupture, cardiac compression, atrial fibrillation, and even sudden death. We describe the case of a 39 year old house wife, of rural origin, with proximity to livestock, who had an asymptomatic pericardial HC along with a symptomatic hepatic HC. She clinically presented with an abdominal lump for one year with recent onset of abdominal pain for 1 month, when radiological imaging confirmed the diagnosis of an unruptured hepatic HC and a pericardial HC. The patient recovered after pericardiectomy along with excision of the HC over the left ventricle and enucleation of hepatic HC, by thoracoabdominal approach. She is doing well after 5 years of followup without recurrence.     

Laparoscopic pericystectomy of liver hydatid cyst

The following report describes a patient with a hydatid cyst located in segment V of the liver which was managed by laparoscopic pericystectomy performed in combination with cholecystectomy. Small hydatid cysts can be removed by the laparoscopic technique; meticulous resection, without opening the cyst, is involved. Compared to the classical approach by laparotomy, this method is less traumatic for the patient, it requires a shorter hospital stay, and it is followed by faster recovery.     

A case of sacral hydatid cyst

INTRODUCTION

Hydatid cyst of bone constitutes only 0.5-2% of all hydatidoses. The thoracic spine is the most common site of spinal hydatidoses. Primary hydatid cyst of the sacral spinal canal is rare.

PRESENTATION OF CASE

A 19-year-old man had cauda equina syndrome with pelvic pain 15 days ago, the pelvic radiography shows a lytic image depend on the left sacral wing. MRI showed an intra-pelvic cystic image invading the sacrum T1 hypointense and T2W hyperintense. The Hydatid serology was positive.Surgical treatment consisted of a wide drainage of hydatid cavity dug in the left sacral wing, and by which it communicated intra pelvic, with removal of the entire cyst by gentle aspiration, abundant rinsing with hypertonic saline, release and sacred roots encompassed in a puddle of fibrosis hydatid.The evolution was good with recovery of perineal sensation and anal tone. The sacroiliac joint was considered stable and did not require synthesis or reconstruction.

DISCUSSION

Hydatid cysts predominantly occur in liver and lungs. Involvement of other organs is uncommon. Neither surgery nor medical therapy is generally effective for bone, especially spinal hydatidosis. The initial treatment of choice is surgical excision for neural decompression and establishing diagnosis. Albendazole is the drug of choice against this disease, when suspected, presurgical use of Albendazole in Echinococcus infestations reduces risk of recurrence and/or facilitates surgery by reducing intracystic pressure.

CONCLUSION

A missed diagnosis of hydatid cyst could be devastating. Hence, hydatid cyst should be kept as a differential diagnosis, when encountered with a cystic lesion of sacrum. In addition, longterm follow-up is mandatory as recurrence is high despite use scolicidal agents.     

Modified capitonnage technique for giant pulmonary hydatid cyst surgery

 Open in a separate windowOBJECTIVESThis study investigated the effectiveness of the modified technique (Aydin Technique), which was applied for capitonnage in the surgical treatment of giant pulmonary hydatid cysts.METHODSTwenty-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.RESULTSThirteen 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.CONCLUSIONSThe 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.     

Calcified cerebral hydatid cyst

Hydatid cyst is rarely observed in the brain (0.5-4.5%). The frequency of calcified cyst is less than 1%. We present a case of a 15-year-old girl with a 5-year follow-up for grand mal seizures that became resistant to three-drug therapy. The CT scan revealed a calcified parieto-occipital lesion. MRI disclosed a suggestive detached membrane. At surgery, the cyst wall was calcified with typical hydatid sand contents. Since surgery, seizure control has been achieved with one drug. Calcification of a cerebral hydatid cyst is exceptional. MRI enabled the diagnosis in this patient.     

Primary hydatid cyst of the retroperitoneum

Retroperitoneal contamination may occur during the natural history of hydatid disease. Primary hydatid cyst of the retroperitoneum is extremely rare. The authors report a case of a giant retroperitoneal hydatid cyst. Clinicians and surgeons must be aware of this possibility and follow a policy of nonsystematic puncture of an abdominal cyst and avoid spillage during surgery. Symptoms are related to the size, location, or ensuing complications of a cyst. Its occurrence should be strongly suspected ahead of any abdominal cyst, especially in an endemic area, where it may act as a parasite. Total and careful surgical excision is the gold-standard therapy.     

Recurrent solitary hydatid cyst of the subcutaneous tissue

A 28-year-old male patient presented with a recurrent swelling in the left lateral chest wall just below the left axilla since seven years. Patient was operated for the same swelling eight years back and its biopsy report showed hydatid cyst. Patient had not taken any antihelminthic post operatively. Based on this, diagnosis of recurrent subcutaneous hydatid cyst was made and total cystectomy was done. Post operatively patient was started on albendazole. On follow up of one year there is no recurrence. Hydatid cyst is caused by the larval stage of Echinococcus. Four species of the Echinococcus tapeworm can produce infection in humans. E. granulosus and E. multilocularis are the most common, causing cystic and alveolar echinococcosis respectively, while E. vogeli and E. oligarthrus have rarely been associated with human infection. Hydatid cyst of the subcutaneous is extremely rare. This case report highlights the rare location of the hydatid cyst as well its recurrence in rare location.     

Peripontomedullary hydatid cyst: Case report and literature review

Introduction: Hydatid cyst represents the parasitic infection by Genus Echenococcus Granulosis. This disease usually involves liver followed by lungs and rarely the CNS. The CNS involvement by the Hydatid Cyst is present in 1–2% of all hydatidosis. Even when it is found in the Brain it presents usually in the supratentorial compartment. However this case was unique in having the Hydatid cyst within the infratentorial fossa. With multiple small cysts, causing mass effect and challenging for surgical resection.Presentation: A 44 years female presented with headache, diplobia and bulbar symptoms, followed by ataxia. Full examination, proper investigations showed the peripontomedullary hydatid cysts. Surgical management is illustrated.Discussion: It is still challenging for the neurosurgeons to operate on these lesions in spite of modern technologies and fancy approaches due to its delicate nature, associated risk of allergic reaction, cyst’s material dissemination and irreversible injury of multiple neurological structure due to prolonged compression of cranial nerves crossing the cerebellopontine angle.Conclusion: In this case report we are presenting a rare case of Multiple Hydatid cysts involving a rare location in the brain; peripontomedullary area and extending all the way down to the foramen magnum. Supported with a literature review in relation to disease etiology, epidemiology, clinical presentation and management.

Anaphylactic shock due to traumatic rupture of pulmonary hydatid cyst: Case report

IntroductionHydatid cyst is an infectious disease caused by « ECHINOCOCCUS GRANULOSIS », it can be asymptomatic or manifests depending on size, location, and relation with other organs, or by complication like rupture. This latter might occur spontaneously or post-traumatic, and it might manifest with an anaphylactic shock, a life-threatening situation.ImportanceAnaphylactic shock is a rare cause of traumatic shock state.Case presentationA 30 years old man with no medical history was admitted to the emergency room after a car accident, on his admission, his Glasgow coma scale was 10/15 with a blood pressure of 80/30 mmHg, he was intubated and stabilized hemodynamically. The full-body CT scan showed no abnormalities except on the thoracic level where it showed a well-limited rounded formation with regular contours containing hydro-aeric level related to ruptured hydatid cyst.After ruling out the diagnosis of hemorrhagic, hypovolemic shock, the diagnosis of anaphylactic shock due to a post-traumatic rupture of the hydatid cyst was maintained.ConclusionPost-traumatic rupture of the hydatid cyst is a rare emergency that requires early diagnosis and management. Surgery remains the principal treatment of ruptured hydatid cyst.Anaphylactic shock is a life-threatening situation with various symptoms; epinephrine is the cornerstone for management of this type of shock.     

Laparoscopic pericystectomy of a liver hydatid cyst

The case of a patient with a liver hydatid cyst in the sixth hepatic segment is reported. Its favorable localization and its calcified state incited us to treat it by laparoscopy. The employed technique is discussed.     

Isolated hydatid cyst of spleen: A rare case with rare presentation

Hydatid cyst is a common health problem of world in sheep grazing area. Liver is the most commonly involved organ. Splenic hydatid cyst is uncommon and its isolated involvement is very rare. We are presenting a case of isolated hydatid cyst of spleen in a sixty one year old female patient with complaints of pain in the left hypochondrium, dyspepsia and features of gastritis for the last 1 year. The diagnosis was confirmed by Contrast enhanced CT scan (CECT). Laparoscopic splenectomy was performed. The aim of this case report is to emphasize that the most important factor in diagnosing splenic hydatid cyst is the awareness of its possibility and the intraoperative precautions which will decrease morbidity and mortality in the postoperative period.     

Unusual presentations of hydatid cyst

Summary Three patients having hydatid disease with unusual localizations are presented. Although hydatid disease is endemic in Mediterranean countries, it rarely occurs subcutaneously. In our cases they were located on: 1) the right temple of the face, 2) the lateral aspect of the left thigh, and 3) the left mastoid region. There were no real indications to suspect hydatid cysts in the first two cases, whereas it was suspected in the third one. They were removed surgically. There were no complications, and there have been no recurrences.     

Laparoscopic cystectomy for splenic hydatid cyst: a case report

Even in countries where it is considered endemic, splenic hydatid cyst is a very rare disease in childhood. Partial or total splenectomy has generally been the treatment of choice for this condition. This is the first report of laparoscopic cystectomy as treatment of isolated splenic hydatid cyst in childhood. A 10-year-old girl with isolated splenic hydatid cyst was successfully treated by laparoscopic cystectomy and splenic preservation. The authors have demonstrated that laparoscopic cystectomy for an isolated splenic hydatid cyst is technically feasible, safe, and is associated with a shorter hospital stay and good cosmetic appearance.
