Giant chylolymphatic mesenteric cyst and its successful enucleation: A case report

INTRODUCTION

Cysts of the mesentery are among surgical rarities. The clinical presentation is not characteristic and in addition, the preoperative imaging although suggestive is not diagnostic in this case ultrasound and CTscan was consistent with giant mesenteric cyst. In most cases, the diagnosis is confirmed after surgical exploration.

PRESENTATION OF CASE

A 42 yrs old male patient on exploratory laparotomy had a 14cm×10cm×10 cm cysts which was seen arising from the mesentery ofdistal jejunum 80cm from the duodeno jejunal flexure. The cyst was enucleated successfully from themesentery without entailing resection. The cyst contained milky white fluid consistent with a chylolymphatic cyst. The diagnosis was confirmed on histopathology which revealed a cyst wall with lymphoidaggregates. After 3 years of follow-up, the patient is doing well and there is no evidence of recurrence.

DISCUSSION

The cysts may be asymptomatic or maymanifest with abdominal pain, distension lump or intestinal obstruction. Our patient was symptomatic with mild and long standing abdominal pain. The definitive diagnosis of these lesions is difficult prior to surgical exploration as there are no pathognomonic symptoms or characteristic imaging findings.

CONCLUSION

Cysts of the mesentery are among surgical rarities. In most of the cases the diagnosis is confirmed after surgical exploration and removal of thecyst. We would like to emphasize the importance of successful enucleation of the cyst irrespective of its size due to its independent blood supply as opposed to enterogenous cyst which requires bowel resection and anastomosis.     

Laparoscopic Management of a Cystic Duct Cyst

Background:

Choledochal cysts are rare cystic dilatations of the biliary tree. Though their cause is uncertain, these cysts are usually referred for surgical resection because of their association with developing malignancy. Traditionally, choledochal cysts have been classified under 5 main types. Not included in this classification are cysts of the cystic duct, a condition that is even rarer, with only 14 cases reported in the literature to date. We describe one such rare case of a cyst of the cystic duct that we successfully treated via laparoscopic resection.

Methods and Results:

A 41-year-old male was found to have a biliary abnormality on a routine follow-up computed tomography (CT) scan for an unrelated medical condition. Further magnetic resonance cholangiopancreatography (MRCP) imaging identified a cystic dilation consistent with a Type II choledochal cyst. Laparoscopic resection was performed using a total of 5 trocars, at which time a cyst of the cystic duct was found instead of the expected Type II choledochal cyst. Intraoperative cholangiography was used as a surgical adjunct to confirm the anatomy, and resection of the cyst was completed without complications.

Conclusions:

Our case adds to the body of reports showing that cysts of the cystic duct, while extremely rare, do occur and need to be recognized. Given the preoperative similarity between cystic duct cysts and other choledochal cysts, proposal for a new “Type VI” category for choledochal cysts may be considered so that clinicians can be prepared for this variation. Once recognized, cysts of the cystic duct can be safely and effectively removed by laparoscopic excision, as we have demonstrated.     

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.     

Ganglion cyst on the posterior cruciate ligament: a case report

Objective:

To present the diagnostic and clinical features of a ganglion cyst located on the posterior cruciate ligament and create awareness amongst clinicians of this uncommon diagnosis.

Clinical Features:

A 24-year old woman complaining of intermittent left knee pain brought on by an increase in mileage during her training for a half-marathon. A diagnosis of mild chondromalacia patella and a ganglion cyst on the posterior cruciate ligament was made via diagnostic imaging.

Intervention and outcome:

Patient was followed up with imaging. The patient chose to withdraw a surgical consult due to patient preference. No conservative treatment was provided.

Conclusion:

Although chondromalacia patella is the more probable, a secondary diagnostic consideration in this patient could be a ganglion cyst. A ganglion cyst on the posterior cruciate ligament is an uncommon diagnosis and the clinical manifestations are variable and non-specific. It is important to be aware of its clinical features and to obtain appropriate methods of imaging to generate the diagnosis promptly.     

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.     

Laparoscopic management of chemical peritonitis caused by dermoid cyst spillage

Background:

Dermoid cyst is the most frequent benign ovarian tumor. Spillage of cyst contents during surgery is common and can rarely lead to chemical peritonitis.

Case Report:

A patient presented 3 days after attempted laparoscopic removal of bilateral dermoid cysts. On examination, she had a low-grade fever, rebound tenderness with guarding, and a markedly elevated white blood cell count. A decision was made to proceed with laparoscopy with the presumptive diagnosis of chemical peritonitis. Laparoscopic findings included residual dermoid cyst contents and extensive filmy adhesions of the bowel and omentum to the peritoneal surface. The chemical peritonitis resolved after laparoscopic removal of residual dermoid cyst content including bilateral salpingo-oophorectomy and copious irrigation.

Conclusion:

Early recognition and prompt treatment by repeat laparoscopic surgery with removal of the remaining cyst contents and peritoneal lavage can be a successful method for treating chemical peritonitis.     

Ganglion cyst in children: Reviewing treatment and recurrence rates

BACKGROUND:

Pediatric hand and wrist ganglia seem to have different epidemiological characteristics than those of adults – a majority are found on the volar aspect of the hands and wrists of patients younger than 10 years of age.

OBJECTIVE:

To determine the epidemiology, etiological factors, clinical presentation, treatment and outcome of patients with ganglion cysts at The Hospital for Sick Children (Toronto, Ontario).

METHODS:

The records of the pathology department at The Hospital for Sick Children were searched for all cases of ganglion cyst operated on between January 2000 and December 2008.

RESULTS:

Thirty-seven patients underwent treatment for symptomatic ganglion cyst. The mean age of the patients was 9.6 years, and there were 23 females. A mobile nodule was the initial presentation of the ganglion in 64% of the cases. Pain was the most common indication for surgical removal. Only 11.4% of patients experienced previous trauma. In 70% of the cases, the diagnosis was made clinically. The most common sites of occurrence were volar wrist (25.7%), dorsal wrist (22.8%) and the volar aspect of the base of the ring finger (17.1%). Surgical excision was the treatment of choice for 94.2% of the patients with symptomatic lesions. The minimum follow-up period was 12 months. Only one patient (2.8%) presented with recurrence in the series.

CONCLUSION:

Although it is possible that these findings might change with longer follow-up, the present data provide information to help guide the treatment of these cysts. Complete surgical removal is a very effective treatment, with low rates of recurrence.     

Splenic cyst during pregnancy

INTRODUCTION

Splenic cyst during pregnancy is rare and may result in spontaneous rupture during the third trimester, which increases perinatal morality.

PRESENTATION OF CASE

We present a 27-year-old healthy Caucasian female who presented at 18 weeks gestation with left flank pain, early satiety and weight loss. Imaging studies demonstrated a large complex multiloculated splenic cyst. The patient underwent a successful laparoscopic splenectomy and delivered a healthy child at term without complication.

DISCUSSION

Spontaneous rupture of a splenic cyst during the third trimester incurs a perinatal mortality rate as high as 70%. Surgical management includes open or laparoscopic splenectomy or fenestration and preservation of the spleen.

CONCLUSION

Laparoscopic splenectomy during the second trimester appears to be safe and offers definitive management of a large symptomatic splenic cyst during pregnancy.     

Laparoscopic-assisted total cyst excision of choledochal cyst and Roux-en-Y hepatoenterostomy

Purpose

The aim of this study was to describe the technical experience and outcome in laparoscopic-assisted total cyst excision of choledochal cyst with Roux-en-Y hepatoenterostomy.

Methods

Thirty-five patients with choledochal cyst were studied. Their age ranged from 3 months to 9 years (average age, 3.6 years). The choledochal cysts were cyst type in 33 cases and fusiform type in the other 2 cases. Four trocars were utilized with 3- to 5-mm instrumentation. Under laparoscopic guidance, the gallbladder and the dilated bile duct were excised completely. The Roux-en-Y jejunojejunostomy was performed extracorporeally by exteriorizing the jejunum through the extending umbilical incision (1.5 to 2 cm), and an end-to-side hepaticojejunostomy was carried out intracorporeally by the hand suture methods.

Results

Average duration of operation was 4.3 hours (range, 3.5 to 7.6 hours), intraoperative blood loss was 5 to 10 mL, and 8 of the 35 patients had associated hepatic ductal stenosis and underwent laparoscopic excision of the cyst and ductoplasty. In 1 of the 8 cases, bile leak was noticed from day 1 through 26 postoperatively. The postoperative course was uneventful in the other 34 patients with a hospital postoperative stay ranging from 3 to 6 days. There were no postoperative complications in the 3-month to 1-year follow-up.

Conclusions

Laparoscopic-assisted total cyst excision with Roux-en-Y hepatoenterostomy is feasible for the treatment of choledochal cyst in children.     

Oversized pseudocysts of the spleen: Report of two cases: Optimal management of oversized pseudocysts of the spleen

INTRODUCTION

Pseudocysts of the spleen are usually asymptomatic and associated with a history of trauma, infection or infarction. In this report, we present two uncommon cases of solitary, oversized pseudocysts of the spleen.

PRESENTATION OF CASE

Two patients (cases A and B), with symptoms of abdominal pain, were investigated. The laboratory and ultrasound examination confirmed the diagnosis of a large, non-parasitic splenic cyst in both cases. Computed tomography described an oversized pseudocyst occupying almost the entire splenic parenchyma in both cases and in patient A, the cyst was located in the splenic hilum. The medical history revealed a previous abdominal injury only in case A. The two patients underwent an open total splenectomy. The pathology examination verified the diagnosis of a non-parasitic splenic pseudocyst.

DISCUSSION

Both patients presented with symptoms, in contrast to the majority of patients with splenic cysts. The medical history of patients with splenic pseudocysts does not always reveal the cause of the pseudocyst formation. Any type of spleen-sparing procedure is not easy to perform in cases of surgical and anatomical difficulty, because of recurrence and the risk of intractable bleeding from the spleen.

CONCLUSION

Partial splenectomy is the recommended method for parenchymal preservation, but total splenectomy is preferred when the splenic cyst is oversized or cannot be excised with safety.     

Intraosseous ganglion cyst of the humeral head in a competitive flat water paddler: case report

Objective

To present the diagnostic and clinical features of an intraosseous ganglion cyst of the humeral head of a female flat water canoe athlete.

Clinical Features

An 18-year old female flat water canoeist complaining of right shoulder pain following a strenuous paddling training camp.

Intervention and outcome

A trial of passive care was conducted, including soft tissue therapy, spinal manipulative therapy, acupuncture, and rehabilitation. The patient seemed to be responding with treatment, but pain would always resume with paddling. A diagnostic ultrasound displayed mild thickening and effusion in the subacromial/subdeltoid bursae. Continued passive care was not able to resolve the symptoms and she underwent an MRI which revealed an intraosseus ganglion cyst subjacent to the lesser tuberosity and floor of the intertubercular groove. A subsequent MRA was ordered to assess the labrum, which was intact, but the cyst had progressed in size. She was referred to an orthopedic surgeon who performed surgery.

Conclusion

An IOG cyst within the humeral head is a rare, potentially painful condition that can mimic other pathologies including impingement and labral tear. It is important to be aware of the clinical features to obtain a prompt diagnosis and appropriate treatment of this condition.     

Laparoscopic removal of a large ovarian mass utilizing planned trocar puncture

Background:

Large cystic ovarian masses pose technical challenges to the laparoscopic surgeon. Removing large, potentially malignant specimens must be done with care to avoid the leakage of cyst fluid into the abdominal cavity.

Case:

We present the case of a large ovarian cystic mass treated laparoscopically with intentional trocar puncture of the mass to drain and remove the mass.

Discussion:

Large cystic ovarian masses can be removed laparoscopically with intentional trocar puncture of the mass to facilitate removal without leakage of cyst fluid.     

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.     

Pandora's box and retrorectal tumors in laparoscopy: A case report and review of the literature

INTRODUCTION

Retrorectal tumors are uncommon and the etiology diverse. Literature to define the preoperative diagnosis and plan the intraoperative management are uncommon.

PRESENTATION OF CASE

We describe a case of a 44 year old patient with a laparoscopic approach for the removal of a retrorectal tumor and emphasize on the preoperative diagnostics and the intraoperative, minimal invasive approach.

DISCUSSION

Especially because these tumors are rare and often an incidental finding in gynecologic surgery, it is important to know the various differential diagnoses and its consequences with the laparoscopic approach.

CONCLUSION

We suggest the laparoscopic approach in cases of retroperitoneal cysts of unknown origin is ideal also because anatomic structures, mostly nerves, can be easily spared.     

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.     

Management of cervical thoracic duct cyst with cyst-venous anastomosis

INTRODUCTION

Cervical thoracic duct cyst (CTDC) is a rare cause of lateral neck mass. Surgical excision with ligation of the cervical thoracic duct is the current standard for definitive management with symptomatic patients. We report the first case of an alternative method of management performing a cyst venous anastomosis for decompression.

PRESENTATION OF CASE

A 77 year old female presented with a six month history of left arm pain, swelling and a left-sided cystic neck mass. She was treated with cyst-venous anastomosis between the cyst wall and the left internal jugular vein. At two year follow-up, she has had resolution of pain and no recurrence of the mass.

DISCUSSION

Many potential etiologies have been proposed for CTDC, though surgical management of this rare problem has consistently required cyst excision and thoracic duct ligation. Few innovative modes of therapy have been developed to address this problem in a less invasive manor. Maintaining a more natural thoracic duct anatomy decreases the likely of complications associated with duct ligation.

CONCLUSION

Cyst-venous anastomosis for the management of CTDC provides an effective, novel form of treatment which maintains the integrity of the thoracic duct and avoids potential complications associated with duct ligation.     

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 Spleen-Preserving Distal Pancreatectomy in a Solitary True Pancreatic Cyst

Background:

Solitary true pancreatic cysts (STPCs), or epithelial cysts, are benign lesions that are extremely rare in adult patients. Advances in radiographic techniques have improved the ability to identify pancreatic cystic lesions. We report a case of a large and symptomatic STPC in a 47-year-old female patient who was treated successfully with spleen-preserving laparoscopic distal pancreatectomy. We also review the clinical and pathologic features of all reported STPCs within the past 25 years.

Database:

To compose the review, we did a search of the international literature for STPCs that had occurred in adults. Fourteen related articles were found describing cases of STPCs. Clinical and pathologic information was collected for all of the reported pancreatic cysts, and a database was formed. STPCs are detected more frequently in women than in men. The mean age of occurrence is 43.2 years, and the mean cyst size is 5.6 cm. Fifty percent of true cysts are located in the head of the pancreas. Size and site are responsible for the symptoms caused, although 22.8% were asymptomatic. Diagnosis was made postoperatively in all cases by histopathologic studies. No case of malignancy was reported in any STPC.

Conclusions:

STPCs are rare and benign lesions commonly discovered incidentally during abdominal imaging. Surgical treatment is considered the appropriate therapy for large and symptomatic STPCs. The definitive diagnosis is established by histopathologic and immunohistochemical studies.     

Congenital stenosis of the hepatic duct at the porta hepatis in children with choledochal cyst

Background

The intrahepatic gallstone is known as one of the complications of choledochal cyst. Stenosis of the hepatic duct may contribute to the formation of the stone. This report describes concurrent congenital stenosis of the hepatic duct identified during the primary operation of choledochal cyst.

Methods

Fourteen children were operated on for choledochal cyst. To identify the concurrent stenosis, cholangiography and inspection of the hepatic duct were performed during the operation. In those patients with identified membranous stenosis, the membrane was resected. In those with nonmembranous stenosis, the wide hilar hepaticojejunostomy was performed after hepatic duct plasty.

Results

Eleven sites of hepatic duct stenosis were identified, 8 membranous stenoses and 3 relative stenoses without membrane. The membranous stenoses were classified into 4 subtypes as follows: a small central opening, a marginal opening, 2 openings, and a bridgelike structure. At the primary surgery on choledochal cyst, those stenoses were released, and the formation of the gallstone has not been observed in 4 to 11 years in all cases.
