Robotic-assisted single-incision laparoscopic surgery (SILS) is becoming an increasingly widespread field worldwide due to the benefits it brings to both the patient and the surgeon. The goal of this study is to develop a secure robotic solution for SILS, focusing specifically on urology, by identifying and addressing various safety concerns from an early design stage. Starting with the medical tasks and protocols, the technical specifications of the robotic system as well as potential; hazards have been identified. By employing competitive engineering design methods such as Analytic Hierarchy Process (AHP), Risk assessment, and Failure Mode and Effects Analysis (FMEA), a safe design solution is proposed. A set of experiments is conducted to validate the proposed concept, and the results strongly support the development of the experimental model. The Finite Element Analysis (FEA) method is applied to validate the mechanical architecture within a set of simulations, demonstrating the compliance of the robotic system with the proposed technical specifications and its capability to safely perform SILS procedures.

Short-Term Outcomes of a Novel Hybrid Technique, Minimally Invasive Laparoscopic and Robotic Surgery (MILAR) Using the da Vinci SP System for Gastric Cancer.
Asian J Endosc Surg
December 2024
Department of Gastric Surgery, National Cancer Center Hospital, Tokyo, Japan.
Background: Robotic surgery may have shown advantages over conventional laparoscopic surgery, but the da Vinci SP system, which utilizes a single incision, has had limited use in gastric cancer surgery. This study aims to evaluate the short-term outcomes of a novel hybrid technique, minimally invasive laparoscopic and robotic surgery (MILAR), with the da Vinci SP system for gastric cancer.
Materials And Methods: This retrospective study reviewed 23 consecutive patients who underwent gastrectomy for gastric cancer using the MILAR technique with the da Vinci SP system between May and October 2024.

Background: Gastric cancer surgery has advanced with minimally invasive techniques. This study compares outcomes between single-incision laparoscopic surgery plus one port (SILS + 1) and conventional laparoscopic surgery (CLS) in treating gastric cancer.
Aim: To explore the curative effect of SILS + 1 and CLS on gastric cancer and their influences on prognosis.

Division of Hepatobiliary and Transplantation Surgery, Department of General Surgery, Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing, China.
Aim: To compare the short-term outcomes between SILC and TILC depending on gallstone size.
Material And Methods: Data from 114 patients with gallstones who underwent cholecystectomy hospitalized in Nanjing Drum Tower Hospital between June 2022 and October 2023 were collected. The gallstone diameter, the operation time, estimated blood loss, post-operative pain, complications post-operation, and length of hospital stay were all collected and examined.
Needlescopic Laparoscope Sleeve Gastrectomy (NLSG): a Potential Surgical Approach.

Department of General Surgery, The Affiliated Wuxi No. 2 Hospital of Nanjing Medical University, Nanjing, China.
Background: Laparoscopic sleeve gastrectomy has become the most popular weight loss surgery currently, but it inevitably leaves multiple small scars in the abdomen. Although the appearance of single-incision laparoscopic sleeve gastrectomy achieve better cosmetic results, it may lead to postoperative complications such as umbilical hernia and umbilical infection. The author has developed a new surgical approach that can compensate for these deficiencies, which we called needlescopic laparoscope sleeve gastrectomy (NLSG).

To evaluate the feasibility, safety, and efficacy of the lateral single-incision laparoscopic totally extraperitoneal (L-SILTEP) approach in patients with inguinal hernia who had contraindications to the midline approach. This study included 58 patients who underwent L-SILTEP. Data on their baseline characteristics and perioperative details were collected.
