Abstract

This study was conducted in Tanta and Kafr-elsheikh university hospitals and included, twenty- two patients presented with simple liver cysts between April 2015 and Oct 2018.

Our aim was to evaluate, feasibility and safety of the laparoscopic management of simple liver cysts.

Laparoscopic unroofing of the cyst was the chosen technique.

Results: The outcome of this technique was satisfactory with minimal morbidity and no mortality, only one patient suffered from postoperative collection treated by ultrasonic guided drainage also no recurrence was experienced during the follow up period.

Keywords: Laparoscopic unroofing; Simple liver cysts

Introduction

Laparoscopic management of simple liver cyst is still not popularized and selecting large accessible either superficial or exophytic peripheral lesions is the role [1].

Also, the general tendency has led to a progressive restriction and tailoring of indications for surgical treatment in benign liver tumors, selecting only patients with huge, specifically symptomatic or compressive benign tumors or patients suffering from hepatocellular tumors associated with a complicated natural history [2,3].

Deep, centrally located lesions near major vascular or biliary structures are not ideal candidates for this technique [3].

But, when comparing surgical trauma required in open hepatic surgery versus the laparoscopic approach, laparoscopy appears to be a promising technique for hepatobiliary surgeons [4,5].

Simple liver cysts located in segment VIII are more prone to early cyst recurrence after laparoscopic deroofing because the residual cyst cavity is immediately covered by the diaphragm, except if in situ omentoplasty is employed to obliterate the cystic cavity [6].

Deeply sited and posterior liver cysts are difficult to reach during laparoscopic exploration [6,7].

These patients may be good candidates for percutaneous alcohol sclerotherapy or for an open surgical approach [8].

Our aim was to evaluate, feasibility and safety of the laparoscopic management of simple liver cysts.

Patients and Methods

This study was conducted in Tanta and Kafr-elsheikh university hospitals and included, twenty- two patients presented with simple liver cysts between April 2015 and Oct 2018.

An approval was obtained from the local ethical committee and an informed written consent was taken from all patients enrolled in this study.

A thorough history, clinical examination and routine laboratory investigations as well as abdominal ultrasound, triphasic CT study of the abdomen and tumor markers to exclude cystic tumors namely {alpha fetoprotein and CA19.9}.

Also, serology to exclude hydatid cyst is a must in all cases.

Patients with Child’s-Pough C and deep or central lesions and those with history of previous liver surgery were excluded from this study.

Operative technique: Four laparoscopic ports were used, but their position was tailored according to the site of the cyst.

Starting by laparoscopic abdominal exploration to confirm the diagnosis and to exclude concomitant lesions or dense adhesions, extensive varices which may abort the technique and to assess the hepatic status.

The falciform, left and right triangular ligaments were taken down according to the site of the cyst to allow good exposure.

Starting with aspirating the fluid inside the cyst to decrease its size, allowing better handling and to exclude hydatid disease surely.

Cyst unroofing was the chosen technique by removing the cyst wall except the posterior one, opening all crypts and cauterization of the posterior wall and then, packing the remaining cavity with omentum.

Finally, tube drain was inserted, and the port sites were closed.

The excised cyst wall together with the aspirated fluid were sent for histopathological examination.

Follow up ranged from 6 months to three years with a mean of 20 months.

Demographic data of the patients and cysts.

Discussion

Laparoscopic management of simple liver cysts is widely adopted nowadays, but not all of them are amenable to laparoscopic treatment C:\pmc\articles\PMC2020682\figure\F0003\[2,3].
