Active gas aspiration in reducing pain after laparoscopic cholecystectomy: a systematic review and meta-analysis of randomized controlled trials.

Background: Postoperative pain is a common issue following laparoscopic cholecystectomy. This meta-analysis aimed to determine if active gas aspiration is more effective than passive gas aspiration in reducing postoperative pain and analgesic requirements.

Methodology: The study conducted a systematic search of various databases, including Embase, Medline, and Cochrane Central Register of Controlled Trials (CENTRAL) via Ovid.

Incidence of superficial left hepatic vein and its usability for graft hepatic vein venoplasty in pediatric liver transplantation.

Backgrounds: The anatomy of the left hepatic vein (LHV) is variable; thus, it should be considered for graft hepatic vein (GHV) venoplasty for left lateral section (LLS) and left liver grafts. This study assessed the incidence of superficial LHV (sLHV) branches according to LHV anatomy and its usability for GHV venoplasty in pediatric liver transplantation (LT).

Methods: This study consisted of three parts: (1) anatomical classification of LHV variations and the incidence of sLHV branches; (2) morphometric simulative analysis of GHV reconstruction and (3) clinical application based on LHV anatomy.

Preoperative estimation of hemi-liver volume using standard liver volume and portal vein diameter ratio in living donor liver transplantation.

Backgrounds/aims: Although body surface area (BSA)-based standard liver volume (SLV) formulae have been used for living donor liver transplantation and hepatic resection, hemi-liver volume (HLV) is needed more frequently. HLV can be assessed using right or left portal vein diameter (RPVD or LPVD). The aim of this study was to validate the reliability of using portal vein diameter ratio (PVDR) for assessing HLV in living liver donors.
