Background: Laparoscopic appendicectomy is one of the most commonly performed abdominal surgical procedures in children, with many different techniques used to isolate and control the appendiceal artery. Previous studies have looked into the utility of different methods of mesoappendix dissection, however these have been predominantly small-scale studies performed on adults.
Aim: The current study aimed to assess the safety and efficacy of 'hook' diathermy as a sole means of mesoappendix dissection in children under 15 years of age undergoing laparoscopic appendicectomy.
Methods: Retrospective review of hospital database and electronic clinical notes of children aged under 15 who underwent laparoscopic appendicectomy at Starship Children's Hospital between 1 January 2007-31 December 2016.
Results: During the study period, 2,793 children had appendicectomy using hook diathermy to dissect the mesoappendix. No children required blood transfusions or return to theatre for bleeding. There were 103 intra-operative complications related to the use of hook diathermy (3.7%), including one case that required conversion to open for bleeding.
Conclusion: Dissection of the mesoappendix using hook diathermy is a safe, quick and effective method during laparoscopic appendicectomy, with low complication and conversion to open rates.

Comparing Thermal Damage Using Monopolar Hook Versus Harmonic Scalpel in Total Laparoscopic Hysterectomy; A Double-Blind Randomized Controlled Trial.

Article Synopsis
- A clinical trial was conducted with 78 women undergoing total laparoscopic hysterectomy to compare the effects of two surgical devices: monopolar hook and harmonic scalpel.
- The primary focus was to measure the thermal damage to cervicovaginal tissues, finding that the monopolar device caused significantly more tissue damage in the right lateral cuff region.
- The harmonic scalpel resulted in less thermal injury, which is crucial for preventing complications, especially in overweight or obese patients.
3D visualization systems improve operator efficiency during difficult laparoscopic cholecystectomy: a retrospective blinded review of surgical videos.

Background: 3D visualization systems in laparoscopic surgery have been proposed to improve manual task handling compared to 2D, however, few studies have compared the intra-operative efficacy in laparoscopic cholecystectomy (LC). The aim of this study is to determine if there is a benefit in intra-operative efficiency when using a 3D visualization system in difficult LC compared to traditional 2D visualization systems.
Methods: Retrospective analysis of 'difficult' LCs (Grades 3 or 4) was completed.

Background: The constrained access associated with transanal minimally invasive surgery has led surgeons to deploy robotic-assisted platforms to offset inherent maneuverability limitations and, perhaps, skills deficits.
Impact Of Innovation: A handheld, powered 5-mm lightweighted laparoendoscopic electromechanical digital device (HandX, HumanXtensions, Israel) with hardware and software components that convert surgical hand movements precisely to the instrument's articulating tip and enable robotic transanal minimally invasive surgery with full tip roticulation for hook diathermy and suturing.
Technology, Materials, And Methods: After bench and biomedical model training, HandX was used in 3 transanal minimally invasive surgery procedures (2 male patients and 1 female patient, mean age 66.

Article Synopsis
- The study investigates complications related to different choledochotomy techniques used during laparoscopic common bile duct exploration (LCBDE) in patients with choledocholithiasis.
- From March 2014 to February 2018, 85 patients underwent LCBDE using three techniques: scalpel/scissor, diathermy hook, and ultrasonic device, with no significant differences in short- or long-term complications among the groups.
- The authors suggest reconsidering the traditional avoidance of energy devices in biliary surgeries but note that more research with a larger sample size is necessary to validate their findings.
