Objectives: We evaluated the efficacy of a new laparoscopic dissecting instrument that fires intermittent bursts of high-pressure carbon dioxide to separate tissue along natural planes.
Methods: The pneumodissector (PD) was used in 2 patients undergoing laparoscopic procedures. Serum creatinine and bicarbonate were measured before and after the procedure, and arterial blood gases were measured before, during, and after use of the PD. Subjective assessment of the ease of dissection with the PD by the first assistant was recorded.
Results: Acidosis and hypercarbia were not observed with use of the PD. The PD facilitated dissection along the iliac vessels, around the kidney, and in the renal hilum.
Conclusions: The PD is a feasible method for rapid, blunt dissection during laparoscopic procedures.

Objective: To study the effect of transversus abdominis plane (TAP) block under direct vision with acupoint injection on the rapid recovery of patients after laparoscopic cholecystectomy.
Methods: Ninety-three patients undergoing laparoscopic cholecystectomy at Hangzhou Hospital of Traditional Chinese Medicine from January 2023 to December 2023 were selected and divided into control, TAP block under direct vision (TAP-DV), and TAP-DV with acupoint injection (TAP-DVA) groups using a random number table method. Postoperative VAS, Ramsay score, IL-6, CRP, and postoperative rehabilitation indices were compared among the three groups.

Department of Cardiothoracic Surgery, Fifth Affiliated Hospital of Sun Yat-Sen University, No.52 East Meihua Road, Zhuhai, Guangdong Province, 519000, China.
Background: Laparoscopic-assisted single-port mediastinoscopic esophagectomy is a safe and effective emerging minimally invasive esophagectomy, but little has been reported about the learning curve for this technology. The goal of the study was to determine the number of procedures to achieve different levels of proficiency on the learning curve.
Methods: This study retrospectively analyzed data from consecutive surgeries performed by the same surgeon at the same center from 2016 to 2021.
Efficacy of ursodeoxycholic acid in reducing the necessity of cholecystectomy due to pre-existing and subsequently formed gallstones in patients who underwent laparoscopic sleeve gastrectomy.

Health Sciences Faculty, Gedik University, Istanbul, Turkey.
Background: In this study, we aimed to investigate whether ursodeoxycholic acid (UDCA) would reduce the necessity of cholecystectomy in patients diagnosed with asymptomatic gallstones after laparoscopic sleeve gastrectomy (LSG) and in patients diagnosed with asymptomatic gallstones before LSG.
Methods: Between July 2020 and November 2022, at least 2-year follow-ups of patients who underwent LSG for obesity were retrospectively analyzed. Patients with pre-existing asymptomatic gallstones during preoperative evaluation, those with UDCA treatment (group 1), and observation group (group 2).

Department of Surgery, School of Medicine and Institute for Medical Science, Keimyung University, Daegu, Korea.
Purpose: Transversus abdominis plane (TAP) block is a promising technique for postoperative pain control. In this study, we aimed to evaluate the efficacy of the TAP block in managing postoperative pain after laparoscopic totally extraperitoneal (TEP) inguinal hernia repair.
Methods: In this retrospective study, medical records of patients who had received ultrasonography-guided TAP blocks after surgery from January 2019 to August 2023 were reviewed and compared with those of patients who had not received.
