Minimally invasive surgery in the elderly population in Korea: temporal trends across major abdominal surgeries.
Article in Journal of minimally invasive surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Korea's rapid transition toward a super-aged society has markedly increased the demand for major abdominal surgery in older adults. Although minimally invasive surgery (MIS) provides perioperative advantages, including reduced surgical trauma, lower blood loss, and accelerated postoperative recovery, it also introduces pathophysiological challenges that require preoperative evaluation and risk stratification. This presidential lecture summarizes trends in geriatric surgery in Korea, highlights perioperative considerations for elderly patients undergoing MIS, and presents longitudinal outcomes from Severance Hospital. Surgical trends and perioperative outcomes were evaluated for major abdominal procedures, including gastrectomy, colectomy, major hepatectomy, and pancreatoduodenectomy (PD), in patients aged ≥70 years. Analyses demonstrated a progressive transition from open surgery toward minimally invasive approaches. Laparoscopic and robotic techniques have become the predominant approaches for gastrectomy and colectomy, including in octogenarians, while MIS adoption for complex procedures, such as major hepatectomy and PD, has also expanded substantially. Comparative analyses within this elderly cohort demonstrated that MIS was associated with superior perioperative outcomes compared with open surgery, including significantly reduced estimated blood loss, shorter hospitalization, and lower rates of clinically significant complications, such as postoperative pancreatic fistula, without compromising procedural safety. Advances in surgical technology and accumulated institutional expertise have established MIS as a feasible, standardized approach for major abdominal surgery in older adults. Integrating comprehensive preoperative assessment, particularly frailty screening, with the selective application of MIS may represent the optimal strategy for reducing operative risk and promoting postoperative functional recovery in geriatric surgical care.
