Introduction: Laparoscopic appendectomy is the current gold standard in treating acute appendicitis. Despite the low frequency of conversion to open surgery, it remains necessary in certain cases. Our primary outcome is to identify the conversion rate of laparoscopic appendectomy to open surgery and how this rate has changed over the learning curve. Secondly, we aim to determine the causes of conversion, their changes in frequency over time and to identify preoperative factors associated with conversion.
Methods: A retrospective comparative study with prospective case registry was conducted. All patients who underwent laparoscopic appendectomy from January 2000 to December 2023 at a high-volume center were analyzed. The series was divided into six periods, each spanning four years. All patients who underwent totally laparoscopic appendectomy (TLA) and those requiring conversion to open appendectomy (COA) were included.
Results: A total of 3411 appendectomies were performed during the study period, with an overall conversion rate of 0.96% (33/3411). Our analysis showed that after the first three periods (12 years), the conversion rate decreased and reached a plateau of approximately 0.4%. The most common causes of conversion were perforation of the appendix base (9/33), abdominal cavity adhesions (8/33) and pneumoperitoneum intolerance (3/33). Age over 65, American Society of Anesthesiologists (ASA) score III/IV and symptom duration exceeding 24 hours were preoperative factors significantly associated with conversion at univariate analysis. However, only age (p 0.0001) and symptoms exceeding 24 hours (p 0.01) remained independently associated with conversion after multivariate analysis.
Conclusion: In experienced centers, conversion from laparoscopic appendectomy to open appendectomy is uncommon, but remains necessary in certain cases. Despite identifying a population with higher association with conversion which should be advised preoperatively, due to the low incidence of conversions once the learning curve is overcome, an initial laparoscopic approach is the preferred choice.

Brain death (BD) leads to complex hemodynamic and inflammatory alterations which may compromise organ perfusion and induce morphologic and functional damage in various organs. The intestine is particularly sensitive to hypoperfusion and donor hypotension usually precludes intestinal donation. Previous studies reported inflammatory intestinal changes following BD but information on mucosal integrity and perfusion are lacking. BD was induced in mice by inflating an epidural balloon catheter. Controls underwent only anesthesia and tracheostomy. Intestinal perfusion was assessed using laser Doppler flowmetry (LDF). Intestinal injury was assessed after 2h of BD by the Chiu-Park score and morphometry. Intestinal tight junction (TJ) proteins (claudin-1, claudin-3, occludin, tricellulin) as well as inflammatory activation (intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and interleukin-6) were also analysed and compared with a sham group. Although blood pressure decreased in BD mice, intestinal perfusion remained similar between BD and sham mice. Histologically, mucosal injury was absent/minimal and TJs appeared well maintained in both groups. BD may trigger intrinsic, autoregulatory mechanisms to preserve microvascular tissue perfusion and mucosal integrity in spite of mild hypotension.

Introduction: Laparoscopic sleeve gastrectomy (LSG) is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). The role of crural repair during LSG is still controversial. The preoperative laxity of the gastroesophageal junction (GEJ), graded by the Hill's classification, is more predictive for postoperative GERD and EE after LSG than the presence of a hiatal hernia seen on endoscopy. Thus, the authors hypothesize that a concomitant crural repair in a specific subgroup of patients with a lax GEJ (Hill's III) may reduce the incidence of postoperative GERD and EE.
Methods: A double-blinded, randomized controlled trial of patients with Hill's III GEJ undergoing LSG will be randomized to a concomitant crural repair (experimental) versus LSG alone (control). Primary outcome measures will be presence of EE at 1-year. Secondary outcome measures will include proton pump inhibitor use, postoperative complications, operative time, blood loss, quality of life, GERD and gastrointestinal symptoms.
Conclusion: Conflicting crural repair results may be explained by differences in preoperative GEJ laxity. Patients with a frank hiatal hernia and patulous GEJ (Hill's IV) have a very high, while patients with an apposed GEJ (Hill's I, Hill's II) have a low incidence of postoperative GERD and EE respectively. Thus, the authors hypothesize that patients with a lax GEJ without frank hiatal hernia (Hill's III), might benefit from a crural repair. This study results can potentially highlight the clinical importance of preoperative endoscopic evaluation of the GEJ in all patients planned for LSG, to determine which subgroup patients may benefit from a crural repair.

简介:腹腔镜袖带胃切除术(LSG)与术后胃食管反流病(GERD)和侵蚀性食管炎(EE)有关。在 LSG 过程中进行嵴修复的作用仍存在争议。根据希尔分类法分级的术前胃食管交界处(GEJ)松弛度比内窥镜检查中发现的食管裂孔疝更能预测 LSG 术后胃食管反流病和 EE 的发生。因此,作者假设在胃食管返流松弛(Hill's III)的特定亚组患者中同时进行嵴修补术可能会降低术后胃食管反流和 EE 的发生率:双盲随机对照试验将对接受 LSG 手术的 Hill's III GEJ 患者进行随机分组,分为同时进行嵴膜修补术(实验组)和单独进行 LSG 手术(对照组)。主要结果指标为 1 年后是否出现 EE。次要结果指标包括质子泵抑制剂的使用、术后并发症、手术时间、失血量、生活质量、胃食管反流病和胃肠道症状:结论:相互矛盾的嵴状修复结果可能是由术前胃食管颈松弛程度的差异造成的。食管裂孔疝和胃食管松弛的患者(Hill's IV)术后胃食管反流和 EE 的发生率非常高,而胃食管贴壁的患者(Hill's I、Hill's II)术后胃食管反流和 EE 的发生率较低。因此,作者推测,胃食管连接松弛而无食管裂孔疝(希尔氏 III 型)的患者可能会从嵴修补术中获益。这项研究结果可能会凸显对所有计划进行LSG手术的患者进行术前GEJ内镜评估的临床重要性,以确定哪些亚组患者可能会从嵴修补术中获益。(Clinicaltrials.gov:NCT05330910,注册日期:2022年4月15日)。

Background: Recycling transplant kidneys, in other words using an allograft which has previously been transplanted in one recipient for transplant in a second recipient, can be a source of opportunity for expanding the pool of available grafts in the United States and beyond.
Summary: We describe a case of renal transplantation from a donor who had undergone a kidney transplant 3 years prior and had good graft function at the time of procurement. The recipient underwent transplantation uneventfully and to date has demonstrated excellent graft function. We also include a literature review of reported cases of recycled/retransplanted kidneys.
Key messages: -Recycling transplanted kidneys is a largely untapped resource which could help decrease the transplant waitlist. -Utilizing such kidneys does need special considerations in terms of procurement technique, backtable, crossmatch, recipient selection and follow-up.

Background Clinical Artificial intelligence (AI) has reached a critical inflection point. Advances in algorithmic science and increased understanding of operational considerations in AI deployment are opening the door to widespread clinical pathway transformation. For surgery in particular, the application of machine learning algorithms in fields such as computer vision and operative robotics are poised to radically change how we screen, diagnose, risk-stratify, treat and follow-up patients, in both pre- and post-operative stages, and within operating theatres. Summary In this paper, we summarise the current landscape of existing and emerging integrations within complex surgical care pathways. We investigate effective methods for practical use of AI throughout the patient pathway, from early screening and accurate diagnosis to intraoperative robotics, post-operative monitoring and follow-up. Horizon scanning of AI technologies in surgery is used to identify novel innovations that can enhance surgical practice today, with potential for paradigm shifts across core domains of surgical practice in the future. Any AI-driven future must be built on responsible and ethical usage, reinforced by effective oversight of data governance, and of risks to patient safety in deployment. Implementation is additionally bound to considerations of usability and pathway feasibility, and the need for robust healthcare technology assessment and evidence generation. While these factors are traditionally seen as barriers to translating AI into practice, we discuss how holistic implementation practices can create a solid foundation for scaling AI across pathways. Key Messages The next decade will see rapid translation of experimental development into real-world impact. AI will require evolution of work practices, but will also enhance patient safety, enhance surgical quality outcomes, and provide significant value for surgeons and health systems. Surgical practice has always sat on a bedrock of technological innovation. For those that follow this tradition, the future of AI in surgery starts now.

Introduction: This study aimed to compare the safety and short-term outcomes of Enhanced Recovery After Surgery (ERAS) with standard care for patients undergoing pancreatoduodenectomy (PD) based on literature published following the first publication of ERAS guidelines for PD.
Methods: Five medical databases were searched for studies that compared ERAS to standard care in adults undergoing PD. Data on postoperative complications, length of hospitalization, readmissions, and time to chemotherapy were analyzed using either a fixed- or random-effects model meta-analysis. Meta-regressions were conducted to investigate the role of operative technique, study origin, and study design.
Results: Our analysis included 22 studies involving 4,043 patients. ERAS was associated with fewer complications (relative risk [RR]: 0.83; 0.75-0.91), particularly Clavien-Dindo (CD) grade 1 and 2 complications (RR: 0.82; 0.72-0.92), delayed gastric emptying (RR: 0.69; 0.52-0.93), and postoperative fistula (POPF) (RR: 0.76; 0.66-0.89), and a shorter time to chemotherapy (standardized mean difference [SMD]: -0.68; 95% CI: -0.88 to -0.48). ERAS did not affect the risk for CD grade 3 and 4 complications (RR: 1.00; 0.72-1.38), post-pancreatectomy hemorrhage (RR: 0.88; 0.67-1.14), length of stay (SMD: -0.56; 95% CI: -1.12 to 0.01), readmission (RR: 1.01; 0.84-1.21), and mortality (RR: 0.81; 0.54-1.22). The continent of origin was an effect moderator in the role of ERAS in CD grade 1 and 2 complications (p = 0.047) and POPF (p = 0.02).
Conclusion: Implementing ERAS principles in PD improves surgical outcomes without compromising safety. ERAS may also accelerate time to chemotherapy, an essential issue for future research.

Introduction: Percutaneous dilatational tracheostomy (PDT) is a safe and cost-effective alternative to surgical tracheostomy. Cirrhotic patients often require ICU admission and prolonged mechanical ventilation. Patients with liver cirrhosis (LC) are known to have coagulopathy and relatively safe and simple procedures such as tracheostomy may be associated with high complication rates, specifically high bleeding rates. Current guidelines are unable to make a specific recommendation on the safety of PDT among cirrhotic patients. We aimed to evaluate the safety of PDT in critically ill patients with LC.
Methods: A retrospective chart review identified critically ill patients who underwent PDT between January 2012 and March 2023. The study group was defined as all patients with a diagnosis of LC. The primary outcome was early (7-day) bleeding, categorized as minor or major. Secondary outcomes were PDT-related and 30-day all-cause mortality. Propensity score matching was performed to adjust the imbalances between the groups.
Results: A total of 1,628 were included in the analysis. Thirty-three of them (2.0%) had LC. In the LC group, only 1 patient (3.0%, 95% CI: 0.0-15.8%) developed early bleeding. Intra-operative, early, late bleeding, and PDT-related mortality rates did not differ significantly between those with LC and those without.
Conclusion: This retrospective cohort study indicates that PDT can be safely performed in critically ill cirrhotic patients, without significantly increasing the risk of bleeding complications.

Introduction: Inadvertent thoracic duct injury is common during esophagectomy and may result in postoperative chylothorax. This study's objective was to investigate utility of patent blue injection as a modality for intraoperative thoracic duct visualization.
Methods: A prospective, single-arm, interventional study of patients undergoing minimally invasive esophagectomy was performed. Patients were injected with patent blue dye into both groins prior to thoracic stage of surgery and assessed for duct visualization. Control group was formed by propensity score matching using retrospectively collected data regarding patients who underwent esophagectomy.
Results: A total of 25 patients were included in analysis, compared to a control of 50 patients after matching. Thoracic duct was visualized in 60% of patients in the study group (15/25 patients). Significant differences were found between study and control groups (p < 0.05) with regards to median operative time (422 vs. 285 min, respectively), overall complications (16 vs. 34%, respectively), and median postoperative length of stay (13.5 vs. 10 days, respectively). There was a difference in rate of chyle leak between study and control groups; however, this was not significant (0 vs. 12%, respectively, p = 0.17).
Conclusion: Patent blue injection represents a simple method for thoracic duct visualization during minimally invasive esophagectomy which may improve surgical outcomes.

Introduction: The aim of this present work was to investigate the mechanism of the microRNA (miR)-216a-5p/FASL axis in mice with acute kidney injury (AKI).
Methods: Mice kidney ischemia/reperfusion (I/R) injury was used as AKI models in this study. I/R mice were injected with miR-216a-5p- and FASL-related constructs to investigate potential mechanisms of kidney protection. Kidney function, inflammation, oxidative stress, and kidney cell apoptosis were assessed after 24 h of reperfusion. In vitro, the hypoxia-reoxygenation (H/R) model was used with kidney tubular epithelial cells (TECs) to mimic kidney I/R injury. H/R-treated TECs were transfected with miR-216a-5p- and FASL-related constructs to detect cell viability, inflammation, and oxidative stress. MiR-216a-5p and FASL expression levels in mouse kidney tissues and in H/R-treated TECs were detected.
Results: MiR-216a-5p was downregulated and FASL was upregulated in kidney tissues of I/R mice and H/R-treated TECs. Upregulating miR-216a-5p attenuated kidney cell apoptosis and the damage of kidney function, and reduced inflammatory factor levels and oxidative stress response in kidney tissues of I/R mice. Upregulating miR-216a-5p advanced cell viability and reduced inflammatory factor levels and oxidative stress response in H/R-treated TECs. Downregulation of FASL effectively reversed the influences of downregulation of miR-216a-5p on kidney injury in mice and kidney TEC survival.
Conclusion: Our study reveals that miR-216a-5p reduces I/R-induced pathological kidney damage in AKI via suppressing FASL.

Introduction: Today, preoperative fasting guidelines have changed, allowing clear liquid intake up to 1 h before surgery. However, concerns remain regarding the risk of aspiration associated with clear liquid intake. This study aimed to investigate the impact of clear fluid given 1 h before surgery on child anxiety and gastric volumes.
Methods: A prospective, randomized, controlled study included 90 patients aged 5-12 years. The patients were randomly allocated into three groups by a computer-generated randomization: group F (n = 30): standard fasting group, group W (n = 30): patients who received oral water at a dose of 5 mL/kg 1 h before surgery, group C (n = 30): patients who received oral carbohydrate fluid at a dose of 5 mL/kg 1 h before surgery. All patients were assessed using the modified Yale Preoperative Anxiety Scale (m-YPAS) before and 1 h after fluid administration. Antral cross-sectional area (CSA) was measured with ultrasonography after intubation, and gastric residual volume (GRV) was calculated. Hemodynamic data, blood sugar level, and parental satisfaction were also recorded.
Results: The m-YPAS scores obtained after 1 h were significantly lower in group C than in the other groups (p < 0.001). Antral CSA and GRV values were lower in group C and group W than in the fasting group (p < 0.001). Parental satisfaction was highest in group C.
Conclusion: This study suggests that allowing a carbohydrate-rich clear liquid intake 1 h before surgery can significantly reduce preoperative anxiety in pediatric patients without increasing the risk of aspiration.
