Three-dimensional (3D) visualization provides better outcome in single-port laparoscopic distal gastrectomy

So Hyun Kang, Yo-Seok Cho, Sa-Hong Min, Young Suk Park, Sang-Hoon Ahn, Do Joong Park, Hyung-Ho Kim. Seoul National University Bundang Hospital

Introduction: The use of a three-dimensional (3D) camera for laparoscopic surgery has been reported in literature. However, there are only few comparative studies demonstrating its benefits, and no reports on the application of 3D vision to single-incision laparoscopic surgery. This study aims to compare 3D vision to the previous two-dimensional (2D) system in solo single-incision laparoscopic distal gastrectomy (SIDG).

Methods: Medical charts of 179 gastric cancer patients who underwent solo SIDG from February 2014 to December 2017 were retrospectively reviewed. Patients were grouped into either 2D group or 3D group depending on the type of camera used. All the operations were performed by a single surgeon using a flexible camera (Olympus, Japan), fixed onto a passive scope holder without the use of a scopist or an assistant. Operative data, postoperative outcome, and early complication were analyzed.

Results: Ninety had their operations under 2D vision and 89 used the 3D scope. In both groups, there was no difference in age, body mass index, staging, and other demographic or histopathologic criteria. Operative time was significantly faster in the 3D group (115.6 ± 34.0 vs. 129.4 ± 38.5 mins., p = 0.012) and EBL was also less (20.7 ± 30.0 vs. 35.1 ± 56.0 ml, p = 0.034). Patients in the 3D group started small fluid diet faster (2.5 ± 0.9 vs. 3.0 ± 1.1 postoperative days, p = 0.006), and were discharged faster (4.4 ± 1.7 vs. 5.2 ± 3.1 postoperative days, p = 0.024). Early complication was also less in the 3D group (2.2% vs. 6.7%) but there was no statistical significance (p = 0.140).

Conclusion: The use of the 3D camera improves operative outcome and hospital stay in patients undergoing solo SIDG.

Respuesta de SAGES al Estudio NordICC sobre el beneficio de las colonoscopias de detección

SAGES desea aclarar los resultados del estudio NordICC y colocarlos en contexto de los esfuerzos de varias agencias nacionales para reducir el riesgo de cáncer colorrectal – la segunda causa de muerte por cáncer más frecuente en los Estados Unidos-, mediante la promoción de la detección y tratamiento oportuno de las lesiones.

SAGES Response to NordICC Study Regarding Benefit of Screening Colonoscopies

The NordICC Study recently published in The New England Journal of Medicine and widely reported on by media outlets has raised questions regarding the benefit of screening colonoscopy in lowering the risk of colorectal cancer and cancer-related deaths among otherwise healthy and symptom-free men and women aged 55 to 64. Provocative headlines and commentaries have […]
