Retrospective search of prospectively maintained database of our surgical department was carried out find all consecutive patients who underwent RSG from April 2023 to August 2024. Each subject who underwent RSG was matched one-to-one with a patient treated with LSG in the same period. Operative time (docking + console time for the robotic procedures), length of stay, need for rescue drugs, and perioperative complications were recorded calculated and compared. A total number of 50 patients (25 RSG and 25 LSG) were included in the present analysis. Operative time in the LSG group was significantly shorter than in the RSG group (57.8 ± 12.3 VS 80.6 ± 16.6 min, p < 0.01), but it was comparable to console time (57.8 ± 12.3 VS 56.9 ± 19.6, p = 0.85). Mean docking time was 23.7 ± 11 min. Length of stay, readmissions, conversion to laparoscopy/open surgery, early complications, and rescue drugs administration were comparable between the two groups. Age, sex, and BMI were not good predictors neither of laparoscopic nor robotic operative time. RSG during the learning curve proved as safe as LSG, but it was associated with longer operative time due to the duration of the docking step. Operation length may become comparable once the learning curve plateau is reached.

This study aimed to evaluate the surgical and survival outcomes of patients aged < 50 years who underwent CR/OPD. A comparative study was conducted on patients who underwent CR/OPD divided into two groups: the young (age < 50 years) and the old (age ≥ 50 years). A total of 555 patients were included in this study, with 53 (9.5%) in the young group and 502 (90.5%) in the old group. Periampullary adenocarcinomas were less common in the young group (32.1% vs. 76.5%), whereas solid and pseudopapillary tumors (9.4% vs. 1.0%) and neuroendocrine tumors (15.1% vs. 3.6%) were more common. Soft pancreatic parenchyma (77.4% vs. 76.5%) and non-dilated (≤ 3 mm) pancreatic ducts (77.4% vs. 62.5%) were more prevalent in the young group. The young group had a shorter length of stay (median, 16 vs. 20 days). No significant differences were observed in the other surgical outcomes and risks, including postoperative pancreatic fistula (POPF) (7.5% vs. 8.0%). Survival outcomes for overall periampullary adenocarcinoma favored the young group, with a 5-year survival rate of 76.4% vs. 46.7% in the old group. In conclusion, RPD in the young patients (< 50 years) is associated with comparable surgical outcomes and favorable survival outcomes for periampullary adenocarcinoma compared with the older patients (≥ 50 years).

Surgeon's experience reflected by annual case load is the most important denominator in thyroid surgery. Nevertheless, even high-volume thyroid surgeons in high-volume centres are not immune to its complications. Despite the advances in surgical technology and techniques, recurrent laryngeal nerve (RLN) injury is still a wellknown complication of thyroid surgery. The considerable postoperative morbidity associated with it and its impact on the patient's overall quality of life make it a dreadful complication of thyroid surgery and a common cause of malpractice accusations. Intraoperative RLN reconstruction is not widely used in clinical practice, but the evidence so far makes it a viable and safe alternative to traditional techniques with better long-term results, as it prevents the occurrence of atrophy of the vocal cord and should be considered in the operating room if possible. Furthermore, immediate reconstruction of an intraoperatively detected RLN injury has been strongly recommended by the 2020 American Association of Endocrine Surgeons guidelines. After neurorrhaphy, RLN regeneration occurs but in a random, misdirected fashion resulting in simultaneous contraction of abductors and adductors. Therefore, normal vocal fold function/mobility is typically not restored. The objective of this technical note is to describe a novel immediate RLN repair technique that has a strong propensity to regenerate and reinnervate laryngeal muscles and potentially restore laryngeal mobility.</p>","PeriodicalId":23391,"journal":{"name":"Updates in Surgery","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142979989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This retrospective study enrolled patients who underwent laparoscopic exploration of the CBD for choledocholithiasis at the Wujin Hospital Affiliated with Jiangsu University between January 2016 and December 2023. Patients were stratified into two groups: individuals who underwent double-needle bi-direction sutures (Bi-direction group, BG) and those who underwent traditional barbed sutures (Normal group, NG). Demographic characteristics, intraoperative parameters, postoperative results, and hospitalization particulars were collected and analyzed. Following propensity score matching, each group comprised 33 patients. The BG exhibited a significantly shorter postoperative extubation time and hospital stay compared to the NG. No significant disparities were noted in intraoperative parameters or postoperative laboratory results between the two groups. Employing double-needle bi-direction barbed sutures for common bile duct (CBD) closure in laparoscopic procedures seems viable and correlates with reduced postoperative recovery durations.

Clinical data on patients diagnosed with PDAC between 2004 and 2020 were downloaded from the Surveillance, Epidemiology, and End Results (SEER) database. Cox regression was performed to identify independent predictors of cancer specific survival (CSS) and overall survival (OS). Survival probability was calculated and compared by the Kaplan-Meier method and log rank test. Akaike information criterion (AIC) and Harrell's C-index were used to evaluate the prognostic ability of each nodal staging system. All three lymph node staging systems were independent predictors of CSS and OS. A higher NLN, a lower N stage, and a lower LNR were associated with improved survival. Compared with N stage, LNR staging performed better with a lower AIC and higher C-index for predicting the prognosis regardless of the sufficiency of retrieved lymph nodes, while NLN staging performed poorly in both the training and validation set. Subgroup analyses showed that the NLN successfully predicted survival outcomes in both lymph node-positive and node-negative patients.

The potential effect of the programmed death-1 (PD-1) inhibitor, when used alongside chemotherapy and antiangiogenic agents in neoadjuvant therapy for gastric cancer, has yet to be explored in the published literature. This study aims to evaluate the efficacy and safety of the S-1 plus oxaliplatin (SOX) regimen when combined with apatinib and camrelizumab (SOXAC) as neoadjuvant therapy for patients with locally advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma. A single-arm, open-label, single-center phase II clinical trial has been designed to evaluate the safety and efficacy of the SOXAC regimen as neoadjuvant therapy for patients diagnosed with locally advanced gastric or GEJ adenocarcinoma (cT2-3N + M0 or T4NxM0). Eligible patients are to receive 2 cycles of SOXAC and 1 cycle of SOX regimen with camrelizumab (SOXC) as neoadjuvant therapy prior to radical surgery, and 3 cycles of SOXC as postoperative adjuvant therapy. The primary endpoint is major pathological remission (MPR), while secondary endpoints include pathological complete response (pCR) rate, R0 resection rate, objective response rate (ORR), operation-related outcomes, and safety. The SOX regimen remains a leading choice for neoadjuvant chemotherapy in Eastern countries. Recent studies suggest that combining chemotherapy, targeted agents, and immune checkpoint inhibitors can enhance the antitumor immune response. This phase II clinical trial seeks to assess the safety and efficacy of the SOXAC regimen as neoadjuvant therapy for patients with locally advanced resectable gastric or GEJ adenocarcinoma, while also exploring the correlation between biomarkers and efficacy.Trial Registration Chinese Clinical Trial Registry (ChiCTR): ChiCTR2200062285 ( https://www.chictr.org.cn/ ).</p>","PeriodicalId":23391,"journal":{"name":"Updates in Surgery","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142910914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
