Laparoscopic Management of Benign Solid and Cystic Lesions of the Liver

Long-term outcomes of resection in patients with symptomatic benign liver tumours

“…This amount can be considered reasonable for an observational study, the more so as in recent literature regarding the subject, sample sizes comprising ranges of 40-179 patients have been used. 1,[21][22][23][26][27][28][29][30] In addition, bias was introduced as patients were not blinded or randomized to resection or not, since this obviously would not be a feasible study design. Resection might not always be possible, for example, for multiple or very large tumours.…”

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

“…In previous reports, laparoscopic approach of cysts located in segments Ⅵ, Ⅶ and Ⅷ were considered a contraindication for this non-invasive procedure [15,18] . However, according to a recent study, location of the cyst should not be a contraindication anymore for a laparoscopic procedure [4] .…”

Evolution and revolution of laparoscopic liver resection in Japan

“…Most early studies in the USA and Europe investigated LLR in benign tumors such as hepatic hemangiomas, adenomas, and cysts 1, 2. Our center (Division of General and Gastroenterological Surgery, Department of Surgery, Toho University Faculty of Medicine) performed the first laparoscopic partial liver resection for metastatic liver cancer (L‐Mets) and hepatocellular carcinoma (HCC) accompanied by cirrhosis in 1993.…”

“…performed LLR for the first time as a method for partial resection of benign tumors 1. After its dissemination, LLR has since been performed proactively for benign tumors with favorable outcomes 2, 71. It is often difficult to differentiate HCC from hepatocellular adenoma or focal nodular hyperplasia72, 73 and needle biopsy has this suggests that there is a risk of implantation in cases of malignant tumor 74.…”
