Clinical feasibility of laparoscopic left lateral segment liver resection with magnetic anchor technique:The first clinical study from China

BACKGROUND Magnetic anchor technique(MAT)has been applied in laparoscopic cholecystectomy and laparoscopic appendectomy,but has not been reported in laparoscopic partial hepatectomy.AIM To evaluate the feasibility of the MAT in laparoscopic left lateral segment liver resection.METHODS Retrospective analysis was conducted on the clinical data of eight patients who underwent laparoscopic left lateral segment liver resection assisted by MAT in our department from July 2020 to November 2021.The Y-Z magnetic anchor devices(Y-Z MADs)was independently designed and developed by the author of this paper,which consists of the anchor magnet and magnetic grasping apparatus.Surgical time,intraoperative blood loss,intraoperative accidents,operator experience,postoperative incision pain score,postoperative complications,and other indicators were evaluated and analyzed.RESULTS All eight patients underwent a MAT-assisted laparoscopic left lateral segment liver resection,including three patients undertaking conventional 5-port and five patients having a transumbilical single-port operation.The mean operation time was 138±34.32 min(range 95-185 min)and the mean intraoperative blood loss was 123±88.60 mL(range 20-300 mL).No adverse events occurred during the operation.The Y-Z MADs showed good workability and maneuverability in both tissue and organ exposure.In particular,the operators did not experience either a“chopstick”or“sword-fight”effect in the single-port laparoscopic operation.CONCLUSION The results show that the MAT is safe and feasible for laparoscopic left lateral segment liver resection,especially,exhibits its unique abettance for transumbilical single-port laparoscopic left lateral segment liver resection.

肾上腺肿瘤腹腔镜手术治疗新进展

目前应用腹腔镜手术治疗肾上腺肿瘤已成为金标准。腹腔镜手术路径有经腹膜后路径、经腹腔镜入路,手术器械有传统的腹腔镜、单孔腹腔镜及近年来发展的机器人手术等。肾上腺是人体一个重要的内分泌器官,对肾上腺肿瘤的手术除了术前做好充分准备,术中操作必须做到精准及微创,特别是较大的肾上腺肿瘤或恶性肿瘤,选择合适的手术路径、掌握各路径的解剖结构及应用相应的手术器械,对手术的成功及术后良好的恢复至关重要。在选择手术路径、各路径的层面解剖及应用手术器械方面近年来均有较多的新进展,同时在手术切除的范围上也有一些新观念。

Single port laparoscopic liver surgery:A minireview

Nowadays,the trend is to perform surgeries with"scarless"incisions.In light of this,the single-port laparoscopic surgery(SPLS)technique is rapidly becoming widespread due to its lack of invasiveness and its cosmetic advantages,as the only entry point is usually hidden in the umbilicus.The interest in"scarless"liver resections did not grow as rapidly as the interest in other scarless surgeries.Hepatopancreatobiliary surgeons are reluctant to operate a malignant lesion through a narrowincision with limited exposure.There are concerns over adverse oncological outcomes for single-port laparoscopic liver resections(SPL-LR)for hepatocellular carcinoma or metastatic colorectal cancer.In addition,getting familiar with using the operating instruments through a narrow incision with limited exposure is very challenging.In this article,we reviewed the published literature to describe history,indications,contraindications,ideal patients for new beginners,technical difficulty,advantages,disadvantages,oncological concern and the future of SPL-LR.

Our initial single port robotic cholecystectomy experience:A feasible and safe option for benign gallbladder diseases

BACKGROUND Although single-port laparoscopic cholecystectomy has been performed for over 25 years, it is still not popular. The narrow working space used in this surgery limits the movement of instruments and causes ergonomic challenges. Robotic surgery not only resolves the ergonomic challenges of single-port laparoscopic surgery but is also considered a good option with its additional technical advantages, like a three-dimensional display and not being affected by tremors.However, the extent to which these technical and ergonomic advantages positively affect the surgical outcomes and how safe the single-port robotic surgeries need to be assessed for each particular surgery.AIM To evaluate the feasibility and safety of single-port robotic cholecystectomy for patients with cholelithiasis.METHODS The electronic records of the first 40 consecutive patients with gallbladder lithiasis who underwent single-port robotic cholecystectomy from 2013 to 2021 were analyzed retrospectively. In addition to the demographic characteristics of the patients, we analyzed American Society of Anesthesiologists(ASA) scores and body mass index. The presence of an accompanying umbilical hernia was also noted. The amount of blood loss during the operation, the necessity to place a drain in the subhepatic area, and the need to use grafts during the closure of the fascia of the port site were determined. Hospital stay, readmission rates, perioperative and postoperative complications, the Clavien-Dindo complication scores and postoperative analgesia requirements were also evaluated.RESULTS The mean age of the 40 patients included in the study was 49.5 ± 11.6 years, and 26 were female(65.0%). The umbilical hernia was present in 24(60.0%) patients,with a body mass index median of 29.3 kg/m^(2) and a mean of 29.7 ± 5.2 kg/m^(2). Fifteen(37.5%) of the patients were evaluated as ASA Ⅰ, 18(45.0%) as ASA Ⅱ, and 7(17.5%) as ASA Ⅲ. The mean bleeding amount during the operation was 58.4 ± 55.8 mL, and drain placement was required in 12patients(30.0%). After port removal, graft reinforcement during fascia closure was preferred in 14patients(35.0%). The median operation time was 93.5 min and the mean was 101.2 ± 27.0 min. The mean hospital stay was 1.4 ± 0.6 d, and 1 patient was readmitted to the hospital due to pain(2.5%).Clavien-Dindo I complications were seen in 14 patients(35.0%), and five(12.5%) complications were wound site problems.CONCLUSION In addition to the technological and ergonomic advantages robotic surgery provides surgeons, our study strongly supports that single-port robotic cholecystectomy is a feasible and safe option for treating patients with gallstones.
