ObjectiveTo systematically review the postoperative complications between robotic-assisted surgery (RAS) and laparoscopic-assisted surgery (LAS) in children with hirschsprung's disease (HSCR). MethodsThe PubMed, Embase, Web of Science, Cochrane Library, CNKI, and WanFang Data databases were electronically searched to collect non-randomized controlled studies related to the objective from inception to May 10, 2025. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4 software. ResultsA total of 7 studies involving 901 children were included. The results of meta-analysis showed that the RAS group had a lower incidence of postoperative enterocolitis than the LAS group (OR=0.64, 95%CI 0.42 to 0.98, P=0.04) and a higher rate of complication-free outcomes (OR=2.16, 95%CI 1.26 to 3.72, P<0.01). No statistically significant differences were found between the two groups in intraoperative duration, intraoperative blood loss, postoperative anastomotic complications, fecal soiling, adhesive intestinal obstruction, wound infection, incisional hernia, perianal infection, or urinary retention (P>0.05). ConclusionCurrent evidence shows that RAS significantly reduces the risk of postoperative enterocolitis and improves the rate of complication-free outcomes in children with HSCR but offers no advantages in intraoperative indicators or other complications. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo systematically review the efficacy and safety of robotic-assisted hepatectomy (RAH) versus traditional laparoscopic hepatectomy (TLH) for hepatic neoplasms.MethodsDatabases including PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang Data and CBM databases were electronically searched to collect cohort studies about the RAH vs. the TLH for liver neoplasms from inception to December 10th, 2016. Two reviewers independently screened the literatures, extracted data and assessed the risk of bias of the included studies. And finally, a meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 17 studies involving 1 389 patients were included. The meta-analysis results showed that: compared to TLH group, RAH group was associated with more estimated blood loss (WMD=39.56, 95%CI 4.65 to 74.47, P=0.013), longer operative time SMD=0.55, 95%CI 0.29 to 0.80, P<0.001), and later in the first nutritional intake time (SMD=1.06, 95%CI 0.66 to 1.45,P<0.001). However, there were no significant differences in the length of hospital stay, conversion to laparotomy, intraoperative blood transfusion, resection rate of tumor margin, complications and 90-day mortality between the two groups.ConclusionCurrent evidence indicates that TLH is superior to RAH in terms of operative time, intraoperative blood loss and the first nutritional intake time, but there are no statistically significant differences in the primary outcomes, suggesting that RAH and TLH have similar efficacy and safety for hepatic neoplasms. Due to the limitation of quality and quantity of the included studies, the above conclusions need to be verified by more high-quality research.
Objective To compare the perioperative outcomes of atypical segmentectomy between robotic-assisted thoracoscopic surgery (RATS) and conventional video-assisted thoracoscopic surgery (VATS) in early-stage non-small cell lung cancer (NSCLC). MethodsThe data of patients who underwent minimally invasive anatomic atypical segmentectomy in our hospital from October 2016 to December 2021 were collected. These patients were divided into a RATS group and a VATS group according to the operation method. Propensity score (PS) matching was used to select patients with close clinical baseline characteristics, and the perioperative results of the two groups were compared. ResultsA total of 1 048 patients were enrolled, including 320 males and 728 females, with a mean age of 53.51±11.13 years. There were 277 patients in the RATS group and 771 patients in the VATS group. After 1∶1 PS matching, 277 pairs were selected. Both groups were well balanced for age, sex, smoking history, body mass index, Charlson comorbidity index, pulmonary function, tumor size, tumor location, and histological type. All patients were R0 resection, and there were no deaths within 30 days after surgery. The RATS group had shorter operative time [85 (75, 105) min vs. 115 (95, 140) min, P<0.001] and less blood loss [50 (30, 100) mL vs. 60 (50, 100) mL, P=0.001]. There were no statistical differences between the two groups in lymph node resection, conversion to thoracotomy, thoracic drainage time, total amount of thoracic drainage or postoperative complications (P>0.05). ConclusionBoth RATS and VATS atypical segmentectomies are safe and feasible for early-stage NSCLC. RATS can effectively shorten the operative time, and reduce blood loss.
