Location affects the management of liver haemangioma: A retrospective cohort study

Clinical impact and role of major vessels involvement in laparoscopic resection for hepatic hemangioma

BACKGROUND

Severe bleeding remains a significant concern in laparoscopic resection for hepatic hemangioma. It is rarely reported that how the degree of major vessels involvement impacts on severe bleeding. The present study primarily aimed to analyze the impacts of the number of involved major vessels (NIMV) during laparoscopic surgery for hepatic hemangioma and evaluate the risk factors associated with increased bleeding.

METHODS

A database search was carried out for consecutive patients who underwent laparoscopic resection for liver hemangiomas at our department from January 2018 to December 2023. The collected data included demographics, characteristics of the hemangiomas, laboratory data, operation method, surgical and postoperative variables.

RESULTS

A total of 72 patients were enrolled in the study. 42 patients were categorized into the group with NIMV < 2, while 30 patients were divided into the group with NIMV ≥ 2. The group with NIMV ≥ 2 demonstrated a significant correlation with special segments, involved multiple segments and diameter of the hemangiomas (P < 0.01). And the perioperative variables including the extent of resection, operative time, blood loss, Pringle maneuver times, postoperative stay, drainage tube duration, and postoperative liver function (ALT, AST) also showed significant differences between the two groups (P < 0.05). Notably, NIMV ≥ 2 was identified as the most important independent risk factor for intraoperative blood loss ≥ 500 ml in laparoscopic surgery for hepatic hemangioma (P = 0.011). For NIMV ≥ 2, the independent risk factor was special segments in multivariate analysis (P = 0.000).

CONCLUSION

The involvement of multiple major vessels (NIMV ≥ 2) was significantly associated with special segments, resulting in increased intraoperative blood loss, operation difficulty, and delayed postoperative recovery. Moreover, it was identified as the single independent risk factor with a considerable risk for increased blood loss during laparoscopic resection for hepatic hemangioma.

Benign liver lesions 2022: Guideline for clinical practice of Associazione Italiana Studio del Fegato (AISF), Società Italiana di Radiologia Medica e Interventistica (SIRM), Società Italiana di Chirurgia (SIC), Società Italiana di Ultrasonologia in Medicina e Biologia (SIUMB), Associazione Italiana di Chirurgia Epatobilio-Pancreatica (AICEP), Società Italiana Trapianti d'Organo (SITO), Società Italiana di Anatomia Patologica e Citologia Diagnostica (SIAPEC-IAP) - Part II - Solid lesions

Benign liver lesions are increasingly diagnosed in daily clinical practice due to the growing use of imaging techniques for the study of the abdomen in patients who have non-specific symptoms and do not have an increased risk of hepatic malignancy. They include simple or parasitic hepatic cysts and solid benign tumors which differ widely in terms of prevalence, clinical relevance, symptoms and natural history and often lead to significant clinical problems relating to diagnosis and clinical management. Following the need to have updated guidelines on the management of benign focal liver lesions, the Scientific Societies mainly involved in their management have promoted the drafting of a new dedicated document. This document was drawn up according to the present Italian rules and methodologies necessary to produce clinical, diagnostic, and therapeutic guidelines based on evidence. Here we present the second part of the guideline, concerning the diagnosis and clinical management of hemangioma, focal nodular hyperplasia, and hepatocellular adenoma.

Impact of open and minimally invasive resection of symptomatic solid benign liver tumours on symptoms and quality of life: a systematic review

BACKGROUND

The value of open and minimally invasive liver resection for symptomatic solid benign liver tumours (BLT) such as hepatocellular adenoma, focal nodular hyperplasia and haemangioma is being debated. A systematic review on symptom relief, quality of life (QoL) and surgical outcome after both open and minimally invasive surgery for solid BLT is currently lacking.

METHODS

A systematic search in PubMed and EMBASE was performed according to the PRISMA guidelines (January 1985-April 2018). Articles reporting pre-and postoperative symptoms or QoL in patients undergoing open or minimally surgery for BLT were evaluated. Methodological quality was assessed using the MINORS tool.

RESULTS

Forty-two studies were included with 4061 patients undergoing surgery for BLT, 3536 (87%) open and 525 (13%) laparoscopic resections. Randomized and propensity-matched studies were lacking. Symptoms were the indication for resection in 56% of the patients. After a weighted mean of 28.5 months follow-up after surgery, symptoms were relieved in 82% of symptomatic patients. Validated QoL tools were used in eight studies, of which two found significant better QoL scores following laparoscopic compared to open surgery.

DISCUSSION

Resection of symptomatic BLT seems safe and relieves symptoms in the vast majority of selected patients. Comparative studies are needed before more firm conclusions can be drawn.
