Importance: This review provides a comprehensive comparison of treatment outcomes between robot-assisted laparoscopic surgery (RLS) and conventional laparoscopic surgery (CLS) based on randomly-controlled trials (RCTs).
Objectives: We employed RCTs to provide a systematic review that will enable the relevant community to weigh the effectiveness and efficacy of surgical robotics in controversial fields on surgical procedures both overall and on each individual surgical procedure.
Evidence Review: A search was conducted for RCTs in PubMed, EMBASE, and Cochrane databases from 1981 to 2016. Among a total of 1,517 articles, 27 clinical reports with a mean sample size of 65 patients per report (32.7 patients who underwent RLS and 32.5 who underwent CLS), met the inclusion criteria.
Findings: CLS shows significant advantages in total operative time, net operative time, total complication rate, and operative cost (p < 0.05 in all cases), whereas the estimated blood loss was less in RLS (p < 0.05). As subgroup analyses, conversion rate on colectomy and length of hospital stay on hysterectomy statistically favors RLS (p < 0.05).
Conclusions: Despite higher operative cost, RLS does not result in statistically better treatment outcomes, with the exception of lower estimated blood loss. Operative time and total complication rate are significantly more favorable with CLS.

Oncological resection and perioperative outcomes of robotic, laparoscopic and open pancreatoduodenectomy for ampullary adenocarcinoma: a propensity score matched international multicenter cohort study.

Background: Ampullary adenocarcinoma (AAC) typically presents at an early stage due to biliary obstruction and therefore might be specifically suitable for minimally invasive pancreatoduodenectomy (MIPD). However, studies assessing MIPD specifically for AAC, including the robotic and laparoscopic approach, are limited. The aim of this study is to compare short- and long-term oncological resection and perioperative outcomes of robotic (RPD), laparoscopic (LPD) and open pancreatoduodenectomy (OPD) performed specifically for AAC.

Objectives: This study sought to assess the advantages of utilizing the single-incision laparoscopic surgery (SILS) procedure for repairing neonatal congenital duodenal obstruction (CDO) in terms of clinical outcomes and complication rates.
Methods: In a retrospective cohort study conducted at a single center, neonates with CDO who underwent SILS were compared to those who underwent conventional laparoscopic surgery (CLS) between January 2018 and December 2022. The demographic and operative characteristics of CDO patients who underwent SILS or CLS were analyzed, including conversion rates and postoperative complications.
