Purpose: To overcome the technical difficulties of single-incision laparoscopic distal gastrectomy (SILDG), needle grasper (Endo Relief^TM)-assisted SILDG (NASILDG) was developed. Here, we compared the operative convenience and postoperative outcomes between SILDG and NASILDG. Materials and Methods: A needle grasper was inserted into the right upper abdomen and used in the NASILDG. We retrospectively reviewed patients who underwent D1 + dissection and delta-shaped Billroth I anastomosis with SILDG or NASILDG performed by a single surgeon between September 2015 and August 2018. Results: The SILDG (male, 50.0%) and NASILDG (male, 60.0%) groups included 10 and 15 patients, respectively. The operative time without combined operation and anastomosis was significantly shorter in the NASILDG group. Early complications and scar characteristics were not significantly different between the two groups. Conclusions: By adding a needle grasper, SILDG became more convenient without decreasing cosmetic results. NASILDG could be a recommended method to reduce the technical difficulty of SILDG.

Background: Although classical multi-port video-assisted thoracic surgery has been widely performed, single-incision thoracoscopic surgery (SITS) is a popular surgical technique for the treatment of primary spontaneous pneumothorax (PSP). However, the inconvenient alignment of instruments and the limited field of view occasionally make surgeons convert from SITS to multi-port surgery or extend the incision. This study aimed to present an easy and safe SITS technique for PSP using a spinal needle. Methods: In total, 139 patients underwent SITS between May 2011 and December 2017. We used a spinal needle to hook the bulla or bleb, and wedge resection was performed through a small incision. Patients' medical records were reviewed retrospectively, and a telephone survey was conducted to investigate the recurrence rate. Results: The mean age of the 139 patients was 23.62±9.60 years. The mean operative time was 36.69±14.64 minutes, and multi-port conversion was not performed. The mean postoperative hospital stay was 3.00±0.78 days, and the mean indwelling chest tube duration was 1.97±0.77 days. No complications were observed. In the mean follow-up period of 86.75±23.20 months, recurrence of pneumothorax was found in 3 patients. Conclusion: We suggest that SITS for PSP with the aid of a spinal needle to replace a grasper is a safe and easy technique that only requires a small incision.

Reduced-port gastrectomy (RPG) includes all procedures derived from various efforts to minimize surgical invasiveness, with single-incision laparoscopic gastrectomy (SILG) being the ultimate reduced-port technique. However, there are challenges related to its feasibility, oncological validity, training, and education. This review describes the current issues and challenges, as well as the future prospects of RPG for gastric cancer. Gastrectomy, which started as an open surgery, has evolved into a laparoscopic surgery. With the advancements in laparoscopic technology, SILG has been used to minimize surgical scarring. However, owing to the technical difficulties of SILG, cases involving the addition of 1 trocar or needle grasper alongside the multichannel port have also been reported. Additionally, 3-port laparoscopic gastrectomy (3PLG) using only 3 trocars is also being performed. RPG, as a concept, includes a range of approaches such as SILG, 2-port laparoscopic gastrectomy, and 3PLG. These techniques aimed to reduce the number of ports or incisions required for laparoscopic gastrectomy. Despite technical difficulties, RPGs offer numerous advantages, including minimal invasiveness, excellent cosmetic outcomes, and the potential for improved postoperative recovery, such as reduced length of hospital stay and post-operative pain. It could be considered similar to conventional laparoscopic gastrectomy, and may not be oncologically inferior. Ongoing studies, such as the KLASS 12, are required to gain further insights.

본 연구에서는 중 소형견에서 1개의 복강경 통로를 통한 내시경적 담낭 제거술을 실시함으로써, 개에서 최소 침습적 수술로 담낭 절제술을 실시할 수 있는 방법을 확립하기 위하여 실시하였다. 실험 동물로 총 3마리의 수컷 비글견 ($10.3{\pm}0.62$ kg)을 이용하였으며 배꼽 주위에 하나의 절개창을 만든 후 단일 통로 내시경 시스템을 장착하였다. 이 시스템을 통해 내시경과 Maryland 복강경용 겸자로 담낭을 견인, 제거하였다. 3마리 모두 성공적으로 담낭 절제술을 실시하였으며, 수술 후 감염과 같은 합병증은 발생하지 않았다. 또한 술전, 술후를 비교한 혈액, 혈청 검사상에서도 특이적인 소견은 관찰되지 않았다. 술후 7일 후에 이루어진 부검 소견에서도 출혈 및 담즙의 유출 및 복막염 등과 같은 부작용은 관찰되지 않았다. 따라서 본 연구를 통해, 단일 통로를 이용한 내시경 유도하 담낭 절제술은 중소형견에서 실시할 수 있는 복강 수술 방법 중 최소한의 절개를 통해 비침습적으로 이루어질 수 있는 유용한 수술 방법이라 할 수 있다.
