The goal of this study was to evaluate the feasibility of totally NOTES performing a cholecystectomy without laparoscopic assistance. A gastroscope was used through a transvaginal access in five acute female pigs. An incision of 2 cm was created in the vagina and pneumoperitoneum was obtained with a Veress needle. The gallbladder was located in the abdominal cavity using endoscopic transillumination for spatial orientation. After the abdominal suspension of the gallbladder the cholecystectomy was completed with the NOTES technique in four animals without complications. In one animal we had technical problems and the procedure was stopped. The mean operative time was 110 minutes. The transvaginal approach provides complete abdominal exploration and both the cystic duct and artery were identified, clipped, and transected. After dissection the gallbladder was removed through the vagina. Our results showed that completely transvaginal NOTES cholecystectomy is a feasible technique performed only with a flexible endoscope.

Background/purpose: The Japanese public health insurance system has recently covered robotic pancreaticoduodenectomy (RPD). This study aimed to review the results of RPD during the introductory period and elucidate its safety and feasibility in Japan.
Methods: Consecutive data of 425 patients who underwent RPD were retrospectively collected from 10 high-volume centers in Japan between April 2020 and September 2022.

Background: Laparoscopic gastrectomy offers advantages in the postoperative period compared to the open approach. Most studies have been performed on distal gastrectomies; however, laparoscopic total gastrectomy (LTG) is not universally accepted. AIM: The aim of this study was to assess the results of LTG, on postoperative morbidity outcomes and long-term survival.

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.

Objectives: Major pathologic response is more common in survival analyses than pathological complete response. Whether major pathologic response can predict survival of patients with resectable stage IIIA non-small cell lung cancer and whether neoadjuvant chemotherapy or immunochemotherapy affect the prognosis of patients remains questionable.
Methods: Patients with resectable stage IIIA non-small cell lung cancer receiving neoadjuvant chemotherapy(≥2 cycles) with/without immunotherapy were enrolled and divided into two groups according to pathological response.
