Minimally invasive management of hepatic cysts: indications and complications

Safely Modified Laparoscopic Liver Resection for Segment VI and/or VII Hepatic Lesions Using the Left Lateral Decubitus Position

Purpose

To explore the feasibility and safety of using the left lateral decubitus position (LLDP) to perform laparoscopic liver resection (LLR) for the treatment of hepatic lesions in segment VI and/or VII.

Patients and Methods

Clinical data concerning 50 patients underwent LLR including 25 patients in the LLDP and the other 25 patients in the routine operative position (ROP) at Shulan (Hangzhou) Hospital Affiliated to Zhejiang Shuren University Shulan International Medical College (Hangzhou, China) and Shulan (Quzhou) Hospital between March 2019 and May 2022 were retrospectively analyzed. All of the patients underwent LLR while in the LLDP or the ROP for the treatment of hepatic lesions located in segment VI and/or VII.

Results

The preoperative clinical and laboratory parameters were comparable between the two groups (P > 0.05). All patients completed the surgery successfully. There were two patients required conversion to open resection in the ROP comparing with zero in the LLDP. The mean operative time was 256.9 ± 132.7 minutes in LLDP and 255.7 ± 92.1 minutes in ROP, while the median perioperative blood loss was 100 mL (range: 50–300 mL) in LLDP and 200 mL (range: 50–425 mL), respectively. The postoperative pathological examination showed that margin-negative resection was achieved all of the cases. The important postoperative parameters all returned to normal within five days after the LLR. The mean postoperative hospital stay (15.6 vs 19.3 days; p < 0.05) and the extraction of the drainage tube time (7.8 vs 10.4 days; p < 0.05) were shorter for patients in LLDP.

Conclusion

The LLDP represents a safe and feasible position for performing LLR in selected patients with lesions in segment VI and/or VII. LLR in the LLDP is helpful in terms of the exposure of the surgical field and the recovery of the patient.

Percutaneous aspiration and sclerotherapy of a giant simple hepatic cyst causing obstructive jaundice: A case report and review of literature

BACKGROUND

Giant simple hepatic cysts causing intrahepatic duct dilatation and obstructive jaundice are uncommon. A variety of measures with different clinical efficacies and invasiveness have been developed. Nonsurgical management, such as percutaneous aspiration and sclerotherapy, is often applied.

CASE SUMMARY

The case is a 39-year-old female with a 5-mo history of cutaneous and scleral icterus, loss of appetite, and dark urine. Lab tests showed jaundice and liver function abnormalities. Imaging revealed a giant simple hepatic cyst obstructing the intrahepatic bile ducts. A combination of percutaneous catheter aspiration and lauromacrogol sclerotherapy was successfully performed and the effects were satisfactory with the size of cyst decreasing from 13.7 cm × 13.1 cm to 3.0 cm × 3.0 cm. Further literature review presented the challenges of managing giant simple hepatic cysts that cause obstructive jaundice and compared the safety and efficacy of a combination of percutaneous aspiration and lauromacrogol sclerotherapy with other management strategies.

CONCLUSION

Giant simple hepatic cysts can cause obstructive jaundice, and a combination of percutaneous catheter aspiration and sclerotherapy with lauromacrogol are suggested to treat such cases.

Laparoscopic liver cyst fenestration with real-time indocyanine green fluorescence-guided surgery: a case report

Laparoscopic fenestration (LF) has recently been considered a standard procedure for nonparasitic symptomatic liver cysts. Here, we report a case of LF that was safely performed using real-time indocyanine green (ICG) fluorescence-guided surgery. A 74-year-old woman presented with right upper abdominal pain and poor dietary intake. The patient was diagnosed with symptomatic liver cysts and underwent LF. One hour before surgery, ICG (2.5 mg) was intravenously administered to the patient. ICG fluorescence imaging clearly showed the biliary ducts and distinguished the cysts from the liver parenchyma. We could resect only the cyst walls as wide as possible under the guidance of both white light and fluorescence imaging. There were no signs of postoperative symptom recurrence. Detection of ICG fluorescence in the liver parenchyma is as important as ICG cholangiography for fenestration. Laparoscopic liver cyst fenestration with real-time ICG fluorescence-guided surgery is safe and can be used as a standard procedure.

Treatment of Hydatid Liver Cyst With Double Percutaneous Aspiration and Ethanol Injection Under Ultrasound Guidance: 6.5-Year Median Follow-up Analysis

PURPOSE

Although hydatid liver cyst (HLC) is a benign disease, treatment is recommended to avoid life-threatening complications. There are several treatment options for HLC: "wait-and-watch," medical or surgical or percutaneous treatment. The purpose of this study was to assess the long-term effectiveness of an alternative of the traditional percutaneous PAIR procedure, called double percutaneous aspiration and ethanol injection (D-PAI).

MATERIALS AND METHODS

This prospective, non-randomized study was conducted from 1988 to 2019 using DPAI procedure characterized by no reaspiration of the ethanol injected to replace the aspirated fluid and repetition of the procedure after 3-7 days.

RESULTS

Two hundred and three patients with 290 HLCs underwent D-PAI. Two hundred and two HLC (160 patients) were univesicular cysts and 88 (43 patient) were multivesicular. Seventeen patients underwent one D-PAI session, 15 patients two sessions, and 18 up to four sessions. The follow-up ranged 0.9-21 years (median 6.5 years). On ultrasound, 188 cysts (64.8%) disappeared; 57 cysts (19.7%) became solid (inactive) and 45 (15.5%) showed a small inactive residual component. Parasitologic cure was very high. The overall response to D-PAI was higher than 90% considering also the procedures carried out after the first D-PAI at the time of recurrence. One patient died for anaphylactic shock. The hospital stay ranged 1-3 days. Smaller cysts (< 5 cm) healed sooner than larger cysts (p < 0.001).

CONCLUSIONS

Long-term analysis showed that D-PAI is a safe and effective option in percutaneous treatment of viable HLC, except for CE2/CE3b in which the recurrences can be observed. This inexpensive and simple procedure can be applied everywhere and especially in developing countries.

Cardiac compression of a hepatic cyst in polycystic liver disease: A rare cause of hemodynamic instability

Polycystic liver disease (PLD) develops due to embryonic ductal plate malformation of intrahepatic bile ducts. Cysts in the liver can range from a simple compression effect to severe liver failure. The most common complication is rupture and inflammation of cyst. It can sometimes progress to the extent of pushing the heart to the left or compressing the inferior vena cava, thereby reducing the venous return. Here, we present a case with giant liver cyst-related symptoms that caused external compression of the right ventricle and atrium. A 71-year-old female patient was admitted to our emergency department with increasing dyspnea, chest pain, and abdominal distension. Her vital signs were as follows: temperature 38°C, pulse 140 beats/min, and blood pressure 70/40 mmHg. Her abdomen was distended, and there was minimal epigastric tenderness. Hepatomegaly was also present. Posteroanterior chest radiography revealed opacity that erased the right diaphragm contour at the right inferior hemithorax. In thoracoabdominal computed tomography, the heart was deviated toward the left due to the compression of a large cystic formation located in the hepatic right lobe, pushing the diaphragm to the superior. Piperacillin/tazobactam 3 g × 4.5 g treatment was initiated, and external drainage was performed by interventional radiology. Following this procedure, significant improvement was observed in the patient’s condition. Her symptoms significantly improved, and the drainage catheter was removed on the seventh day. Hepatic cysts in patients with PLD may compress adjacent structures, and cardiac compression can be life-threatening if hemodynamic instability occurs.
