How to Build a Simple and Safe Laparoscopic Hydatid Evaluation System

Background:

One of the most common problems faced in laparoscopic treatment of hydatid cysts is the difficulty in evacuating the particulate contents (daughter cysts and laminated membrane). Although various instruments and laparoscopic techniques have been described to evacuate the contents of hydatid cysts, most are not available at many surgical centers.

Methods:

By assembling disposable, cheap, and available anesthesia equipment with common laparoscopic instruments, a laparoscopic system was made to evacuate the contents of a hydatid cyst. Ten patients with hepatic hydatid disease underwent laparoscopic surgery using this new hydatid system between June 2011 and January 2013.

Results:

The procedure was completely straightforward. Twelve hydatid cysts (2 patients had 2 separated cysts) were evacuated without any spillage. All patients were followed for at least 8 months, with no evidence of recurrence.

Conclusions:

This simple apparatus, which can be assembled anywhere, was safely used to evacuate the contents of hydatid cysts without causing any spillage.     

Surgical management of symptomatic hydatid liver disease: experience from a Western centre

Background

Hydatid liver cysts are rare in North America. The objective of this study was to determine the optimal surgical management for hydatid liver cysts treated outside endemic areas.

Methods

We reviewed the cases of consecutive patients who underwent management of hydatid liver cysts. Radical liver resections were compared with other types of procedures. Clinical presentation, investigations, perioperative outcomes and long-term follow-up were evaluated. We evaluated disease recurrence using the Kaplan–Meier method.

Results

Forty patients underwent surgery for hydatid liver cysts. Most patients had single (68%) right-sided (46%) cysts with a median size of 10 cm. Most (83%) underwent liver resection with or without drainage/marsupialization. Radical liver resection was carried out in 60% (19 major, 5 minor). Additional procedures were required in 50% (biliary fistulization 30%, diaphragmatic fistulization 20% or paracaval location/ fusion 8%). Postoperative complications occurred in 48%. The median follow-up was 39 months. The 3-year recurrence-free survival was significantly different between patients who had radical resection and those who had other procedures (100% v. 71%, p = 0.002).

Conclusion

The surgical management of hydatid liver cysts in North America remains rare and challenging and is frequently associated with fistulizing complications. Excellent long-term outcomes are best achieved using principles of radical liver resection that are familiar to North American surgeons.     

Traumatic rupture of hydatid cysts

Objective

To stress the relation between rupture of hydatid cysts and trauma.

Design

A case series.

Setting

A university-affiliated hospital for emergency medicine.

Patients

Four college students who suffered traumatic rupture of hydatid cysts. All injuries were sustained during sporting activities.

Interventions

Resection or unroofing of the cysts with careful removal of all hydatid elements, and suture-plication of the residual liver cavities.

Results

The ruptured cysts were located in the liver, spleen and splenic flexure of the colon. At exploration, additional hydatid cysts were found, usually in the liver. Treatment resulted in complete recovery in all patients.

Conclusions

Traumatic rupture of hydatid cysts related to sporting activities may be commoner than indicated by the rarity of reports. Increased awareness of this possibility in areas where hydatid disease is endemic is encouraged.     

Endoscopic management of biliary hydatid disease

Objective

To determine the effect of endoscopic sphincterotomy in the management of biliary hydatid disease.

Design

A case study between January 1992 and December 1994.

Setting

A university-affiliated hospital in Adana, Turkey.

Patients

Five patients with biliary hydatid disease, in which the cyst had ruptured into the biliary tree. The follow-up ranged from 3 to 12 months.

Intervention

Endoscopic sphincterotomy.

Main Outcome Measures

Morbidity, mortality and recurrence of the disease.

Results

All patients underwent successful endoscopic sphincterotomy, including removal of daughter cysts. During the follow-up period, ultrasonography and laboratory investigations showed complete cure in all patients. There were no complications due to endoscopic sphincterotomy.

Conclusion

Endoscopic sphincterotomy is the treatment of choice for the management of hydatid cysts that have ruptured into the biliary tract causing obstructive jaundice.     

Surgical treatment of hydatid cysts of the lung: analysis of 405 patients

Objective

The choice of operation, postoperative success and complications of surgery in patients with pulmonary hydatid cysts.

Design

A series of patients seen over 15 years.

Setting

A university clinic.

Patients

Four hundred and five patients (209 male, 196 female) ranging in age from 4 to 72 years (mean 29 years). Most (367 patients) had isolated lung cysts; 38 had both liver and lung cysts.

Interventions

A variety of procedures to remove cysts, including enucleation and capitonnage, wedge resection, segmentectomy, lobectomy and pneumonectomy. Six patients with bilateral cysts were operated on through a median sternotomy approach. Others underwent posterolateral thoracotomy.

Main outcome measures

Value of diagnostic tests, the most efficacious approach for cyst removal and recurrence and death rates.

Results

Chest radiography gave a correct diagnosis in 99% of patients. The Casoni and Weinberg tests were discontinued because of high false-negative rates (up to 35%). Hospital mortality was 1.2% and postoperative complications occurred in 5.2%. The recurrence rate was 1.5%.

Conclusions

Lung-preserving surgical interventions are the treatment of choice for pulmonary hydatid disease. In patients with bilateral cysts, the median sternotomy approach is preferred, and in the patients with right lung disease and coexisting liver cysts the transdiaphragmatic approach is the one of choice to remove cysts in 1 stage.     

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.     

Postoperative recurrence of cystic hydatidosis

Background

Surgical management is the basic treatment for hydatid disease. Overall, the recurrence rate appears to be high (4.6%–22.0%). The purpose of this study was to report our results in the management of recurrent hydatid disease, evaluating the methods for identifying recurrence, prognostic factors and therapeutic options.

Methods

We retrospectively reviewed the medical records of patients who underwent surgery for cystic hydatidosis between 1970 and 2003.

Results

Of the 584 patients who underwent surgery during our study period, follow-up was complete for 484 (82.8%). Cysts recurred in 51 patients (8.7%). Abdominal ultrasonography and computed tomography appeared to be efficient for diagnosing recurrence. The 2 most important determinants for recurrence were minute spillage of the hydatid cyst and inadequate treatment owing to missing cysts or incomplete pericystectomy. All but 2 recurrences required surgery. There were 14 postoperative complications for a rate of 27.0%. Thirteen re-recurrences were observed in the follow-up of these patients and also required surgery.

Conclusion

Avoidance of minute spillage of cyst contents and cautious removal of the parasite with as much of the pericyst as possible are fundamental objectives of primary hydatid surgery. Conservative surgery (removal of the cyst contents plus partial pericystectomy with drainage when necessary) plus chemotherapy and local sterilization is suggested for both primary and secondary operations and appears to achieve satisfactory long-term results. Radical surgery (resection, cystopericystectomy) is preferred only in select patients.     

Laparoscopic treatment of hydatid cyst of the liver in children. A report on 34 cases

Purpose

This study evaluated the safety and efficiency of laparoscopically treated liver cysts in children.

Methods

From September 2001 to July 2004, 34 patients underwent laparoscopic treatment of hydatid cysts of the liver. All patients had chest x-ray, abdominal sonography, and hydatid serology. The different stages of the procedure were the same as in open surgery: puncture, aspiration, injection of scolicidal agent, reaspiration, removal of proligerous membrane, and resection of the dome.

Results

The patients' mean average age was 7 years and 7 months (range, 3-14 years). The number of cysts ranged from 1 to 10 with a diameter of 40 to 150 mm (mean diameter, 65.5 mm). One case had a mesenteric associated hydatid cyst, another splenic hydatid cyst. The average length of hospital stay was 5 days (range, 4-14 days). No per- or postoperative complications were reported. At 12 to 45 months follow-up, no recurrence has been reported.

Conclusion

Laparoscopy represents an excellent approach for the treatment of hydatid cyst of the liver in children.     

Cryosurgery for malignant tumours of the liver

Objective

To evaluate the safety and efficacy of ultrasound-guided cryosurgery to treat malignant tumours of the liver.

Design

A prospective nonrandomized trial. The follow-up was complete and ranged from 8 to 35 months.

Setting

A university-affiliated hospital.

Patients

Ten patients with secondary malignant tumours of the liver; 1 with primary hepatoma.

Interventions

Computed portography for preoperative staging; laparotomy and ultrasonographic examination of the liver; cryosurgical ablation of liver tumours with or without a concomitant resection. Thirteen procedures were performed on 11 patients.

Main Outcome Measures

Preoperative morbidity, disease-free and overall survival.

Results

Of 24 lesions frozen, the procedure on 4 lesions was considered a technical failure because of persistent disease. There were no perioperative deaths. One patient had a liver abscess that resolved with percutaneous drainage. One patient had a biliary fistula that resolved spontaneously, and one had a transient rise in the serum creatinine level. Of 11 patients treated, 7 had a recurrence in the liver (persistent disease in 2 and new liver metastases in 5); 2 of these patients died. One patient died of distant disease with no local recurrence. At the time of writing, one patient was alive with extrahepatic disease and no local recurrence and two were free of disease.

Conclusions

Cryosurgery of the liver is a relatively safe procedure that allows treatment of otherwise un-resectable malignant disease. Proof of long-term benefit requires further experience and follow-up.     

Minimally Invasive Treatment of Liver Hydatidosis

Background and Objectives:

Open surgery has been the mainstay treatment for liver hydatidosis in the past. Today, for treatment of simple and uncomplicated cysts, we have a variety of choices: antihelmintic therapy, the PAIR (puncture, aspiration, injection, and respiration) technique, and the laparoscopic approach. We reviewed our series of 267 cases of hepatic hydatidosis submitted to surgery over a period of 20 years, from 1995 through 2014, comparing the results of these minimally invasive treatments.

Methods:

In 92 patients (25.7% of cases) who presented with complicated liver hydatid cysts, we performed open surgery. In 16.4% of cases (59 patients), we used a laparoscopic approach, and in 208 patients (57.9% of cases), we used the PAIR technique. All patients were monitored after surgery for a mean of 61.7 months (range, 16–127). Postoperative follow-up consisted of clinical examination, laboratory investigation, abdominal ultrasound, and magnetic resonance imaging.

Results:

Almost all patients (198, 95.2%) treated with the PAIR technique and 55 patients (93.2%) treated with the laparoscopic approach were cured. Six patients (2.8%) from the echo-guided puncture group had to undergo a repeat of the procedure because the cavity did not disappear after 2 years. In 4 patients (2%), we performed open surgery for 2 biliary fistulas and 2 hepatic abscesses. Four patients from the laparoscopic group needed additional procedures. Open surgery was necessary in 2 patients for a recurrence after 2 years; 1 patient had developed a liver abscess and the other had a biliary fistula.

Conclusions:

In conclusion, open surgery remains the viable option for complicated cysts, with biliary communication, with multiple daughter vesicles, or with calcified walls. For simple, uncomplicated hydatid cysts, both methods (the PAIR technique and laparoscopic procedure) are safe and efficient, with very good results and low morbidity rates.     

Primary hydatid cyst of pancreas with acute pancreatitis

Context

Primary hydatid disease of the pancreas is very rare and even rarer to cause pancreatitis.

Case report

We report the case of a 20-year-old man who presented with abdominal pain and an epigastric mass. A diagnosis of a pancreatic hydatid cyst was established by ultrasonography and CT scan before surgery. The treatment consisted of laparoscopic cyst evacuation with omentoplasty. The recovery was uneventful and the patient has remained symptom free so far.

Conclusions

Hydatid disease should be considered in the differential diagnosis of all cystic masses in the pancreas, especially in the geographical regions where the disease is endemic.Keyword: Primary hydatid cyst of pancreas     

Laparoscopic Drainage of Pyogenic Liver Abscess

Background and Objectives:

Pyogenic liver abscesses are mainly treated by percutaneous aspiration or drainage under antibiotic cover. If interventional radiology fails, surgical drainage becomes necessary. Recently, we performed laparoscopic liver abscess drainage successfully, and we aimed to focus on the topic in light of a systematic review of the literature.

Methods:

A 22-year-old man was admitted with a 4.5-cm multiloculated abscess in the left lobe of the liver. The abscess did not resolve with antibiotic-alone therapy. Percutaneous aspiration was unsuccessful due to viscous and multiloculated contents. Percutaneous catheter placement was not amenable. Laparoscopic abscess drainage was preferred over open abscess drainage. We used 3 trocars, operation time was 40 minutes, and blood loss was minimal. In the mean time, we searched PubMed using the key words [(liver OR hepatic) abscess*] AND [laparoscop* OR (minimal* AND invasiv*)].

Results:

Postoperative recovery of the patient was uneventful, and the patient was asymptomatic after 3 months of follow-up. In the literature search, we found 53 liver abscesses (51 pyogenic and 2 amebic) that were treated by laparoscopy. Mean success rate was 90.5% (range, 85% to 100%) and conversion rate was zero.

Conclusion:

Treatment of liver abscess is mainly percutaneous drainage. Laparoscopic drainage should be selected as an alternative before open drainage when other modalities have failed.     

Role of Conventional and Diffusion-Weighted Magnetic Resonance Imaging of Spinal Treatment Protocol for Hydatid Disease

Objective:

To demonstrate the role of magnetic resonance imaging (MRI) in determining the treatment protocol for hydatid disease of the spine.

Design:

Case report; literature review.

Findings:

Diffusion-weighted MRI can help differentiate complicated infected hydatidosis from abscesses, epidermoid cysts from arachnoid cysts, and benign from malignant vertebral compression fractures. It is also helpful in differentiating between abscesses and necrotic tumors.

Conclusion:

Diffusion-weighted MRI can help differentiate between infections requiring immediate surgery and those that can be treated medically with antihelmintic treatment.     

Ganglion cyst of the foot treated with electroacupuncture: A case report

Objective:

To present the clinical management of a ganglion cyst presenting on the dorsolateral aspect of the foot.

Clinical Features:

A 45-year-old female cyclist complaining of ganglion cyst following training period.

Intervention and Outcome:

Patient was treated with high-frequency electroacupuncture in four consecutive sessions over four weeks, and reported resolution of the cyst following therapeutic intervention.

Conclusions:

Ganglion cysts of the foot are relatively rare connective tissue tumours with variable treatment approaches. Electroacupuncture may be a novel and non-invasive conservative approach for the treatment of ganglion cysts. Further evaluation of the efficacy of such treatment is warranted.     

Single-Incision Laparoscopic Surgery Versus Standard Laparoscopic Surgery for Unroofing of Hepatic Cysts

Background and Objectives:

The aim of this report is to document the feasibility and safety of umbilical single-incision laparoscopic liver cyst unroofing in the treatment of simple hepatic cysts in a retrospective case-control study. We also introduce some operative skills for single-incision laparoscopic surgery.

Methods:

From May 2009 to July 2011, 15 patients underwent umbilical single-incision laparoscopic liver cyst unroofing. All the clinical data were retrospectively analyzed. Another 15 simple liver cyst patients who received standard laparoscopic liver cyst unroofing at our hospital during the same period—with a similar age, nature of the cyst, and position to the single-incision group—were selected to undergo a case-control study. The operative time, blood loss, recovery time of gastrointestinal function, volume of postoperative drainage, postoperative drainage time, postoperative hospitalization time, and postoperative recurrence rate were compared between the two groups.

Results:

There was no significant difference between the single-incision group and standard group in operative time (58.3 ± 7.43 minutes vs 58.7 ± 6.14 minutes), blood loss (17.0 ± 3.19 mL vs 14.7 ± 1.86 mL), recovery time of gastrointestinal function (2.5 ± 0.22 days vs 2.4 ± 0.22 days), volume of postoperative drainage (408.0 ± 119.5 mL vs 450.0 ± 89.5 mL), postoperative drainage time (2.6 ± 0.55 days vs 3.7 ± 0.59 days), or postoperative hospitalization time (4.8 ± 0.44 days vs 5.2 ± 0.56 days) (P > .05). The postoperative follow-up period was 1 to 24 months.

Conclusions:

Compared with standard laparoscopic liver cyst unroofing, single-incision laparoscopic liver cyst unroofing shows no significant difference during the overall treatment process. In addition to the advantages of less trauma, more rapid recovery, and shorter hospital stay, single-incision laparoscopic surgery can reach the effect of “no scar” and can be safely and effectively carried out.     

Marfan syndrome and symptomatic sacral cyst: Report of two cases

Context

Meningeal abnormalities such as dural ectasia are seen in Marfan syndrome, but spinal meningeal cysts are rarely seen. These cysts usually asymptomatic and often found incidentally on magnetic resonance imaging, large cysts may cause neurological deficits and pain secondary to nerve root compression.

Design

Case reports.

Findings

Two patients with Marfan syndrome presented with urinary symptoms secondary to dural ectasia and sacral cysts. Patient 1 had a history of low back pain, erectile dysfunction, and occasional urinary incontinence and groin pain with recent symptom worsening. He underwent L5 partial laminectomy and S1-S2 laminectomy with sacral cyst decompression. Nine weeks later, he underwent drainage of a sacral pseudomeningocele. Pain and urinary symptoms resolved, and he remains neurologically normal 2 years after surgery. Patient 2 presented after a fall on his tailbone, complaining of low back pain and difficulty urinating. Physical therapy was implemented, but after 4 weeks, urinary retention had not improved. He then underwent resection of the sacral cyst and S1-S3 laminectomy. Pain and paresthesias resolved and bowel function returned to normal. Other than needing intermittent self-catheterization, all other neurologic findings were normal 30 months after surgery.

Conclusion/clinical relevance

Surgical goals for sacral cysts include resection as well as closure of the dura, which can be challenging due to thinning from ectasia. Neurosurgical intervention in Marfan syndrome is associated with a high risk of dural tears and osseous complications, and should be performed only when symptoms are severe.     

Thoracic Myelopathy Secondary to Intradural Extramedullary Bronchogenic Cyst

Background/Objective:

To report a case of thoracic myelopathy secondary to intradural extramedullary bronchogenic cyst.

Study Design:

Case report.

Methods/Findings:

A 20-year-old man presented to the emergency department with increasing back pain and lower-extremity weakness. Magnetic resonance imaging demonstrated a cystic lesion at the T4 level with mass effect on the spinal cord.

Results:

The lesion was resected, and histopathologic evaluation showed a cyst lined by respiratory-type epithelium consistent with a bronchogenic cyst.

Conclusions:

Intradural extramedullary bronchogenic cysts of the thoracic spine have been reported previously but are extremely rare. The treatment of choice is surgical resection.     

A giant adrenal cyst difficult to diagnose except by surgery

Introduction

Adrenal cysts represent rare clinical entities. Although surgical indications are well defined, pitfalls arise from the failure to establish an accurate preoperative diagnosis. Cystic lesions of other abdominal organs especially the pancreas complicate the diagnostic field.

Presentation of case

We present the case of a giant adrenal cyst in a young female causing diagnostic dilemma. Imaging studies revealed a large cystic lesion of uncertain origin located between the spleen and the tail of the pancreas. It was decided to perform a laparotomy which confirmed the presence of an adrenal cyst and enucleation of the cyst was performed. Examination at one year confirmed no complications.

Discussion

Adrenal cysts should always be included in the differential diagnosis of cystic abdominal lesions.

Conclusion

When the preoperative diagnosis is uncertain, surgical intervention can be both diagnostic and therapeutic.
