Results of percutaneous sclerotherapy and surgical treatment in patients with symptomatic simple liver cysts and polycystic liver disease

AIM: To evaluate the results of the treatment of simple liver cysts (solitary and multiple) and polycystic liver disease (PLD) using percutaneous sclerotherapy and/or surgical procedures in a single tertiary referral centre. METHODS: Retrospective analysis of 54 patients referred for evaluation and possible treatment of simple liver cysts (solitary and multiple) and PLD, from January 1997 to July 2006. RESULTS: Simple liver cysts were treated in 41 pts (76/) with a mean size of 12.6 cm. The most common reason for referral was abdominal pain or discomfort (85/). Percutaneous sclerotherapy was performed as initial treatment in 30 pts, showing cyst recurrence in 6 pts (20/). Surgical treatment was initially performed in 11 pts with cyst recurrence in 3 pts (27/). PLD was treated in 13 pts (24/) with a mean size of the dominant cyst of 13 cm. Percutaneous sclerotherapy for PLD was performed in 9 pts with recurrence in 7 pts (77.8/). Surgical treatment for PLD was undertaken in 4 pts (30.8/) with recurrence in all. Eventually, 2 pts with PLD in the presence of polycystic kidney disease underwent liver-and kidney transplantation because of deterioration of liver and kidney function. CONCLUSION: The majority of patients with simple liver cysts and PLD are referred for progressive abdominal pain. As initial treatment, percutaneous sclerotherapy is appropriate. Surgical deroofing is indicated in caseof cyst recurrence after percutaneous sclerotherapy. However, the results of percutaneous sclerotherapy and surgical treatment for PLD are disappointing. Partial liver resection is indicated when there is suspicion of a pre-malignant lesion.

Long-term results of laparoscopic fenestration for patients with congenital liver cysts

BACKGROUND: The feasibility and immediate outcome of laparoscopic fenestration for patients with congenital liver cysts have been generally recognized. The aim of the present study was to assess the long-term results after laparoscopic fenestration. METHODS: A retrospective study was performed on 44 patients with congenital liver cysts who had undergone laparoscopic fenestration between June 1998 and December 2004. Among them, 30 were women and 14 men, aged 57 years on average (range 18-76 years). While 14 patients had solitary cysts, 20 had multiple cysts, and 10 had polycystic liver disease. The results of laparoscopic fenestration, including mortality, morbidity, mean postoperative hospital stay, and recurrences of cysts were evaluated. RESULTS: There was no perioperative death and the morbidity rate was 11% (5/44). All complications were treated conservatively. The mean postoperative hospital stay was 4 days. A mean follow-up of 57 months showed that the rates of cyst recurrence and symptom recurrence were 9% and 4.5%, respectively. CONCLUSION: Laparoscopic fenestration as a feasible and safe treatment procedure for patients with congenital liver cysts can yield very good long-term results.

Predisposing factors and surgical outcome of complicated liver hydatid cysts

AIM: To evaluate the predisposing factors for peritoneal perforation and intrabiliary rupture and the effects of these complications on surgical outcome in liver hydatid disease.METHODS: A total of 372 patients with liver hydatid cysts who had undergone surgical treatment were evaluated retrospectively. Twenty eight patients with peritoneal perforation, 93 patients with spontaneous intrabiliary perforation, and 251 patients with noncomplicated hydatid cysts were treated in our clinics.RESULTS: When the predisposing factors for complications were evaluated, younger age, superf icial position, and larger cyst dimensions (P < 0.05; range, 0.0010.017) increased peritoneal perforation rates. It was shown that older age increased cyst dimensions, and presence of multiple and bilobar cysts increased intrabiliary rupture rates (P < 0.05; range, 0.0010.028). Partial pericystectomy and drainage was the most frequent surgical procedure in all groups (71.6%). The incidence of postoperative complications in the peritoneal perforated group, in the intrabiliary ruptured group, and in the noncomplicated group was 25%, 16.1% and 5.5%, respectively. When compared, complication rates were significantly different (P = 0.002). When length of hospital stay was compared, there was no signif icant difference between the groups (P > 0.05). The overall recurrence rate was 3.8% (14 patients), but there was not any statistical difference among the patient groups (P = 0.13). The early postoperative mortality rate was 1.1%. CONCLUSION: In peritoneally perforated and intrabiliary ruptured cases, the most important steps are irrigation of the peritoneal cavity and clearance of the cystic material from the biliary tree.

Intestinal obstruction due to giant liver cyst:A case report

BACKGROUND Congenital hepatic cysts are relatively rare but are now diagnosed earlier and more frequently with a routine prenatal ultrasound.Solitary liver cysts are divided into simple and solitary intrahepatic biliary cysts,depending on the biliary connection.While some solitary liver cysts are symptomatic in childhood,even in newborns,they are often found incidentally in adults.CASE SUMMARY A 3-mo-old female infant was admitted to Mogadishu Somali Training and Research Hospital with recurrent vomiting,respiratory problems,and abdominal bloating complaints.On examination,the abdomen was greatly distended and extremely tight.She had repeated vomiting for 3 d,no stool output,and decreased urine.The abdominal ultrasonography detected a solitary cystic lesion measuring 10 cm×10 cm×14 cm,extending from the liver or right kidney to the pelvis.In the magnetic resonance imaging examination of the patient,a solitary cystic structure of 10 cm×10 cm×14 cm in the right abdomen was observed,extending to the pelvis and possibly originating from the liver.The patient was operated via fenestration after her fluid and electrolytes improved.Oral nutrition was initiated on the 2nd postoperative day,and the drain was removed on the 5th postoperative day.The patient visited the outpatient clinic control 1 mo later with no clinical complaints.CONCLUSION Congenital liver cysts are usually followed without complications.They rarely reach gigantic dimensions and may cause respiratory distress,intestinal obstruction and recurrent vomiting.Surgery can provide quite successful outcomes in the treatment of giant sized simple liver cysts.

Case of takotsubo cardiomyopathy after surgical treatment of liver hydatid cyst: A case report

BACKGROUND Takotsubo cardiomyopathy,also called apical ballooning syndrome,is a disease that is often triggered by stress factors in postmenopausal women and mimics acute coronary syndrome.The aim of this article is to draw attention to takotsubo cardiomyopathy after surgical treatment of liver hydatid cyst.CASE SUMMARY A 50-year-old diabetic and hypertensive female patient was evaluated preoperatively before general surgery for liver hydatid cyst,and no cardiac problems were found.The patient was discharged on the 3rd postoperative day without any postoperative complications.On postoperative day 5,the patient presented to the emergency department with fever,shortness of breath,chills,and shivering and was hospitalized with the diagnosis of pneumonia.The troponin levels remained high during follow-up.Echocardiography was performed on postoperative day 7,after which the patient was referred to a tertiary center with the diagnosis of non-ST-elevation myocardial infarction due to akinesia in the apical region.Coronary angiography performed at the tertiary center showed normal coronary anatomy,and the patient was diagnosed with takotsubo cardiomyopathy.CONCLUSION Takotsubo cardiomyopathy mimicking myocardial infarction without ST segment elevation may develop after surgical treatment of liver hydatid cyst.

Laparoscopic fenestration of multiple giant biliary mucinous cystadenomas of the liver

Biliary cystadenomas of the liver are rare, cystic neoplasms of the biliary ductal system usually occur in middle aged women. We report a case of synchronous multiple huge biliary mucinous cystadenomas with unique features. This is, according to our knowledge, the first report in the literature about three synchronously occurring hepatobiliary cystadenomas. Cystadenomas have a strong tendency to recur, particularly following incomplete excision, and a potential of malignant transformation. A therapeutic re-evaluation may be necessary when the diagnosis of hepatobiliary cystadenoma is made after the operation and an open liver resection should be considered.

Levovist ultrasonography imaging in intracystic hemorrhage of simple liver cyst

The differential diagnosis between intracystic hemorrhage and cystadenocarcinoma of the liver is often difficult even with the use of various imaging modalities. A 73-year-old woman was admitted to our hospital with the complaint of right upper quadrant pain. Ultrasonography (US) demonstrated a heterogeneous echogenic cyst measuring 11 cm × 8 cm in size in S2 of the liver, indicated intracystic hemorrhage of simple liver cyst or cystadenocarcinoma, but the differential diagnosis was considerably difficult. Levovist (Schering, Berlin, Germany) US revealed no enhancement of the intracystic structures, suggesting a clot in the case of intracystic hemorrhage. An operation was performed and the resected lesion showed a solitary benign liver cyst, measuring 5.5 cm × 4.7 cm × 8.5 cm containing a large blood clot. The patient had an uneventful recovery after the surgery. Levovist US may play an important role in discrimination between intracystic hemorrhage of simple hepatic cysts and cystadenocarcinoma of the liver.

A symptomatic cyst of the ligamentum teres of the liver: A case report

Cysts of the liver ligaments are extremely rare and cysts of the ligamentum teres of the liver have been sporadically reported in the literature during the last century. The present report describes a case of a symptomatic patient with a cyst of the ligamentum teres of the liver. The patient presented with right upper quadrant pain and indigestion during the last 2 years. Ultrasound and computed tomography scans revealed a water-density mass attached to the anterior abdominal wall, but definite diagnosis could not be reached. The cyst was completely excised during laparotomy. Cysts of the ligamentum teres of the liver, although infrequent, may produce clinical symptoms and require excision. Ultrasound and computed tomography scan preoperatively cannot rule out malignancy, thus exploratory laparotomy and total resection of these lesions are necessary.

Destructive granuloma derived from a liver cyst: A case report

We herein report the case of an idiopathic liver cystic mass which aggressively infiltrated the thoracoabdominal wall. A 74-year-old woman who had a huge cystic lesion in her right hepatic lobe was transferred to our hospital for further examinations. Imaging studies revealed a simple liver cyst, and the cytological findings of intracystic fluid were negative. She was followed up periodically by computed tomography （CT） scans. Seven years later, she complained of a prominence and dull pain in her right thoraco-abdominal region. CT revealed an enlargement of the cystic lesion and infiltration into the intercostal subcutaneous tissue. We suspected the development of a malignancy inside the liver cyst such as cystadenocarcinoma, and she therefore underwent surgery. A tumor extirpation was performed, including the chest wall, from the 7th to the 10th rib, as well as a right hepatic Iobectomy. Pathologically, the lesion consisted of severe inflammatory change with epithelioid cell granuloma and bone destruction without any malignant neoplasm. No specific pathogens were evident based on further histological and molecular examinations. Therefore the lesion was diagnosed to be a destructive granuloma associated with a long-standing hepatic cyst. Since undergoing surgery, the patient has been doing well without any signs of recurrence.

Radical versus conservative surgical treatment of liver hydatid cysts： a meta-analysis

To date, the efficacy of radical surgery （RS） versus conservative surgery （CS） for liver hydatid cysts （LHC） remains controversial. This meta-analysis was conducted to compare the two interventions. PubMed, Embase, and Web of Science were searched from their inceptions until June 2016. Meta-analysis was performed using STATA 12.0 software. We identified 19 eligible studies from 10 countries by retrieval. In total, 1853 LHC patients who received RS were compared with 2274 patients treated by CS. The risk of postoperative overall complication, biliary fistula, and recurrence was significantly lower, and operation time was significantly longer in the RS group. However, no statistically significant differences were found in terms of mortality risk and the duration of hospital stay between RS and CS. No significant publication biases were observed in all the above analyses. In conclusion, RS reduces the rates of postoperative complications and recurrence, whereas no trend toward such a reduction in mortality was observed in LHC patients.

Ruptured hydatid cyst in a patient with shock

Echinococcosis is a severe helminthic zoonosis largely caused by Echinococcus granulosus and frequently encountered in endemic areas.The liver and lung are the most frequently involved organs.Cyst rupture into the peritoneal cavity represents a rare but serious complication.Herein,we describe an acute occurrence of anaphylactic shock due to a spontaneous rupture of hydatid cyst in a 21-year-old Turkish patient unwittingly infected by Echinococcosis.Resection surgery of the perforated cyst in combination with cleaning of the abdominal cavity was performed.The patient rapidly improved and no relapse occurred during a follow-up of 8 months.Anaphylaxis is a serious complication of hydatid cyst rupture and needs to be promptly diagnosed.The main objective of our report is to underscore this life-threatening complication that should be considered when anaphylactic shock of unknown origin occurs,even in non-endemic regions.Moreover,we emphasize the need for a radical surgical approach to avoid widespread dissemination.

Adenocarcinoma and infection in a solitary hepatic cyst: A case report

Solitary non-parasitic liver cysts are being increasingly diagnosed due to the increased use of abdominal sonography. The majority of solitary liver cysts are asymptomatic; however, there are some complications which include infection, perforation, spontaneous hemorrhage, obstructive jaundice and neoplastic degeneration. In some cases a cystic liver lesion may mimic a tumor and is difficult to differentiate with standard imaging studies or fine needle aspiration cytology. Here in, we report a case of adenocarcinoma arising in a solitary hepatic cyst complicated with Klebsiella pneumoniae infection. High levels of CEA in the cyst fluid levels suggested malignancy, which was confirmed by pathology of the resected specimen.

Fatal thrombotic complications of hepatic cystic compression of the inferior vena: A case report

Of 5% of patients who develop liver cysts, only 10-15%of them come for medical attention, typically because of dull right upper quadrant pain, abdominal bloating or early satiety. We treated a 77-year-old female with a rare complication of inferior vena cava thrombosis. The patient expired due to septic shock and multiple organ failure.

A novel flexible endoscope-based transumbilical fenestration of liver cyst

Laparoscopic procedure as a minimally invasive surgery had been introduced into many abdominal surgery. Smaller incisions of the abdominal wall reduce postoperative pain and the risk of wound complications, and provide an excellent cosmetic result compared with open surgery. Flexible endoscope-based transgastric, transcolonic, or transvaginal surgery for abdominal exploration, cholecystectomy, appendectomy, and tubal ligation may further reduce the surgical invasion.
