The Prognostic Impact of Minimally Invasive Esophagectomy on Survival After Esophagectomy Following a Delayed Interval After Chemoradiotherapy: A Secondary Analysis of the DICE Study.

To evaluate prognostic differences between minimally invasive esophagectomy (MIE) and open esophagectomy (OE) in patients with surgery after a prolonged interval (>12wk) following chemoradiotherapy (CRT). Previously, we established that a prolonged interval after CRT before esophagectomy was associated with poorer long-term survival. This was an international multicenter cohort study involving 17 tertiary centers, including patients who received CRT followed by surgery between 2010 and 2020. Patients undergoing MIE were defined as thoracoscopic and laparoscopic approaches. A total of 428 patients (145 MIE and 283 OE) had surgery between 12 weeks and 2 years after CRT. Significant differences were observed in American Society of Anesthesiologists grade, radiation dose, clinical T stage, and histologic subtype. There were no significant differences between the groups in age, sex, body mass index, pathologic T or N stage, resection margin status, tumor location, surgical technique, or 90-day mortality. Survival analysis showed MIE was associated with improved survival in univariate ( P =0.014), multivariate analysis after adjustment for smoking, T and N stage, and histology (HR=1.69; 95% CI: 1.14-2.5) and propensity-matched analysis ( P =0.02). Further subgroup analyses by radiation dose and interval after CRT showed survival advantage for MIE in 40 to 50Gy dose groups (HR=1.9; 95% CI: 1.2-3.0) and in patients having surgery within 6 months of CRT (HR=1.6; 95% CI: 1.1-2.2). MIE was associated with improved overall survival compared with OE in patients with a prolonged interval from CRT to surgery. The mechanism for this observed improvement in survival remains unknown, with potential hypotheses including a reduction in complications and improved functional recovery after MIE.

Evolution of Pancreas Transplantation At A Single Institution-50+ Years and 2500 Transplants.

To describe the evolution of pancreas transplantation, including improved outcomes and factors associated with improved outcomes over the past 5 decades. The world's first successful pancreas transplant was performed in December 1966 at the University of Minnesota. As new modalities for diabetes treatment mature, we must carefully assess the current state of pancreas transplantation to determine its ongoing role in patient care. A single-center retrospective review of 2500 pancreas transplants was performed over >50 years in bivariate and multivariable models. Transplants were divided into 6 eras; outcomes are presented for the entire cohort and by era. All measures of patient and graft survival improved progressively through the 6 transplant eras. The overall death-censored pancreas graft half-lives were >35 years for simultaneous pancreas and kidney (SPK), 7.1 years for pancreas after kidney (PAK), and 3.3 years for pancreas transplants alone (PTA). The 10-year death-censored pancreas graft survival rate in the most recent era was 86.9% for SPK recipients, 58.2% for PAK recipients, and 47.6% for PTA. Overall, graft loss was most influenced by patient survival in SPK transplants, whereas graft loss in PAK and PTA recipients was more often due to graft failures. Predictors of improved pancreas graft survival were primary transplants, bladder drainage of exocrine secretions, younger donor age, and shorter preservation time. Pancreas outcomes have significantly improved over time through sequential, but overlapping, advances in surgical technique, immunosuppressive protocols, reduced preservation time, and the more recent reduction of immune-mediated graft loss.

Wireless In-Ear Communication for Total Joint Arthroplasty: A Simulated Operating Room Evaluation

BackgroundEffective surgical team communication is a key component of patient safety. However, communication failure is common and has previously been identified as one of the leading causes of error. Nonetheless, there has been a lack of innovation in this domain. Contemporary communication technology may hamper loud noises frequently encountered during total joint arthroplasty surgery to allow the surgical team to communicate safely and effectively. The objective of this study was to assess whether the use of in-ear communication devices during simulated arthroplasty surgery could improve communication compared to standard of loud voice communication. MethodsThis was a randomized simulation study designed to evaluate differences in communication. Participants were recruited to engage in simulations of total joint arthroplasty with in-ear wireless communication devices and traditional methods. Data collected included participant demographics, sound level exposure, and communication effectiveness using a created list of phrases commonly involved in arthroplasty surgery. A System Usability Scale questionnaire and survey comparing participant experiences was given. ResultsFifteen participants were recruited. The median age was 29 years (standard deviation 2.9) and 66% were women. There were significant differences in the percent of correctly identified phrases (78.6% vs 44%), mean effectiveness (7.9/10 vs 4.9/10) and mean clarity (8/10 vs 4/10) in favor for the wireless in-ear communication simulation (P < .001 for all). Out of the 10 questions in the System Usability Scale questionnaire, 4 exhibited significant differences, favoring the use of in-ear communication, while the others showed no difference. The mean level of sound recorded was 86 dB in the in-ear device and 87.6 dB in the control group (P = .680). ConclusionsWireless in-ear communication appears to be safe and effective during total joint arthroplasty surgery which may promote efficiency and patient safety. Further, in-ear communication systems can dampen the loud and potentially damaging noise in orthopaedic procedures and may protect surgeons exposed to loud noises.

ClassIIb histone deacetylase participates in perioperative neurocognitive disorders in elderly mice via HSP90/GR signaling pathway.

Multiple factors contribute to the development of perioperative neurocognitive disorders (PND). This study was designed to investigate whether Histone Deacetylase 6 (HDAC6) was involved in the formation of postoperative cognitive dysfunction in elderly mice by regulating the degree of acetylation of heat shock protein (HSP90) and related protein functions and quantities. C57BL/6J male mice were randomly divided into six groups: control naive (group Control), anesthesia (group Anesthesia), splenectomy surgery (group Surgery), splenectomy surgery plus dissolvent (group Vehicles), splenectomy surgery plus the inhibitor ACY-1215 (group Ricolinostat), and splenectomy surgery plus the inhibitor RU-486(group Mifepristone). After the mice were trained for Morris Water Maze (MWM) test for five days, anesthesia and operational surgery were carried out the following day. Cognitive function was assessed on the 1st, 3rd and 7th days post-surgery. The hippocampi were harvested on days 1, 3, and 7 post-surgeries for Western blots and ELISA assays. Mice with the splenectomy surgery displayed the activation of the hypothalamic-pituitary-adrenal axis (HPA-axis), marked an increase in adrenocorticotropic hormone (ACTH), glucocorticoid, mineralocorticoid at the molecular level and impaired spatial memory in the MWM test. The hippocampus of surgical groups showed a decrease in acetylated HSP90, a rise in glucocorticoid receptor (GR)-HSP90 association, and an increase in GR phosphorylation and translocation. HDAC6 was increased after the surgical treated. Using two specific inhibitors, HDAC6 inhibitor Ricolinostat (ACY-1215) and GR inhibitor Mifepristone (RU-486), can partially mitigate the effects caused by surgical operation. Abdominal surgery may impair hippocampal spatial memory, possibly through the HDAC6-triggered increase in the function of HSP90, consequently strengthening the negative role of steroids in cognitive function. Targeting HDAC6- HSP90/GR signaling may provide a potential avenue for the treatment of the impairment of cognitive function after surgery.

Updates on temporomandibular joint reconstruction following ablative surgery.

Considerations regarding reconstruction of the temporomandibular junction (TMJ) following ablation have been underreported in head and neck surgery literature. Here, we discuss the complexity of reconstructing this unique joint and highlight the benefits and drawbacks of free tissue transfer. Additionally, we address the growing role of customized alloplastic implants and virtual surgical planning technologies in TMJ reconstruction. Technological advances in computerized manufacturing, 3D printing, and virtual reality have led to a recent burgeoning in patient-specific customization that may become the method of choice in these complex reconstruction cases. Since trauma and malignancy rarely compromise the entire TMJ, guidelines currently do not exist regarding how to best reconstruct the region in these unique cases. The methods that work in ankylosis and other intrinsic joint diseases are likely less appropriate in this patient population. Recent literature has reported improved patient outcomes and reduced operative times with virtual surgical planning techniques that may optimize autogenous graft approaches.

Validity of laparoscopic surgery for lower gastrointestinal perforations.

This study aimed to clarify the validity of laparoscopic surgery for lower gastrointestinal perforation by comparing the clinical outcomes of laparoscopic and open emergency surgery. We reviewed the data of patients who underwent surgery for lower gastrointestinal perforation. Patients were categorized into two groups: the laparoscopic group who underwent laparoscopic surgery, and the open group who underwent laparotomy. Clinical and operative outcomes between the two groups were evaluated. A total of 219 patients were included in the study. There were 66 and 153 patients with small bowel and colorectal perforations, respectively. The median operative time in the laparoscopic group was shorter than that in the open group (126 min vs. 146 min, p = .049). The mean amount of intraoperative blood loss was significantly lower in the laparoscopic group (50.4 mL vs. 400.1 mL, p < .001). The incidence of postoperative complication was higher in the open group (20.0% vs. 66.5%, p < .001), especially wound infection (0% vs. 26.3%, p = .002). Median hospital stays were 14 days and 24 days in the laparoscopic and open groups, respectively (p < .001). In the laparoscopic group, hospital mortality was 0%. The laparoscopic approach for small bowel and colorectal perforation in an emergency setting is a safe procedure in carefully selected patients and may contribute to decreased intraoperative blood loss, shortened hospital stay, and decreased incidence of postoperative complications, especially wound infection.

Fidelity of Enhanced Recovery Protocol Implementation With Assessment of Hospital-Specific Materials

IntroductionVariability in implementation of enhanced recovery protocols (ERPs) often reduces the effects of an intervention on clinical outcomes. This study aimed to evaluate hospital-level implementation fidelity to a pediatric gastrointestinal surgery ERP by assessing site-specific implementation materials. MethodsThis document analysis study operationalized implementation fidelity as adherence to the creation of specified materials at each study site. During the 12-mo implementation phase within the stepped-wedge cluster randomized control trial, ENhanced Recovery In CHildren Undergoing Surgery, study sites were provided with materials (e.g., order sets), access to peer-counseling, and given key ERP elements spanning multiple phases of care. Sixteen of the 18 total study sites submitted implementation materials, including 14 anesthesia protocols, 11 order sets, and 16 sets of patient/family education materials. These materials were assessed and graded for fidelity using prespecified criteria. Hospital-level fidelity scores could range from 0 to a maximum score of 18, and were categorized as either high or low, based on whether the score was above or below/equal to the median. Descriptive statistics and Wilcoxon rank sum test were used for analysis. ResultsThe overall hospital-level median fidelity score for inclusion of ERP elements in the implementation materials was 10.5. The median score was 12.8 at nine high-fidelity sites and was 5.6 at nine low-fidelity sites (P < 0.01). Higher adherence was noted for avoiding prolonged fasting (n = 16/18 hospitals; 89%) and preventing nausea and vomiting (n = 16/18 hospitals; 89%) in anesthesia protocols and/or order sets. Lower adherence was noted for incorporation of minimally invasive surgical techniques (n = 2/18 hospitals, 11%) and of preoperative optimization of medical comorbidities (n = 0/18 hospitals, 0%) in implementation materials. ConclusionsDespite substantial resources to promote ERP elements, there was wide variation in fidelity for incorporating ERPs into implementation materials among hospital sites. Development of high-fidelity implementation materials for complex ERPs for gastrointestinal surgery in children may require longer than 12 months. Additional implementation strategies, resources, and modification of implementation-focused materials may be needed.

Mandibular asymmetry. Hemimandibular hyperplasia vs. hemimandiubular elongation

Introduction. Hemimandibular hyperplasia and elongation create a developmental asymmetry characterized by volumetric changes of the hemimandible. Both entities cause progressive aesthetic and functional problems causing depression with poor quality of life. The treatment of these anomalies is combined, orthodontic and surgical Material and methods. The study was based on the analysis of bibliographic sources as well as the rehabilitation of two patients diagnosed with hemimandibular hyperplasia and hemimandibular elongation. Results. The specialized literature proposes a variety of surgical techniques for osteotomy of the mandible to correct mandibular asymmetries. The surgical planning of the interventions was carried out using the digital protocol, with the manufacture of intermediate and final splints. Conclusions. Contemporary digital medical imaging in combination with virtual surgical planning allows a patient specific treatment protocol, a fact that significantly contributes to optimizing not only the treatment plan but also the surgery itself.

Comparison Between Ketamine and Dexmedetomidine in Achieving Opioid Sparing Sedoanalgesia in Patients Following Open Heart Surgery: A Randomized Clinical Trial

Background: Opioid-sparing sedoanalgesia relies on non-opioid multimodal analgesic and sedative agents. It is being developed to decrease or eliminate opioid use for the management of acute postoperative pain to avoid opioid complications. This study aimed to compare ketamine and dexmedetomidine for their efficiency and safety in inducing opioid-sparing sedoanalgesia in patients following open heart surgery. Methods: Ninety adult cardiac patients who underwent open heart surgery were enrolled. They were randomly divided into three groups. Group D received a dexmedetomidine infusion of 0.1– 0.2 μg/kg/hour, group K received a ketamine infusion of 1–2 μg/kg/min while group C received a placebo as a control group. Drugs were given after the operation in the surgical intensive care unit. Total postoperative opioid consumption was the primary outcome. Richmond agitation sedation scale, visual analog pain scale, time to first analgesic request, patient satisfaction, and incidence of any complications were recorded. Results: In this study, we found that the median (interquartile range) postoperative opioid consumption was significantly lower in groups D and K than in group C (156 (40), 140 (83), 185 (110); p &lt; 0.001). Richmond agitation sedation scale was statistically significant until 6 hours postoperative (p-value: &lt; 0.05). Patient satisfaction score was higher in groups D and K than in group C (p-value: 0.005). On the other side, there is no statistically significant difference between the three study groups regarding time to first analgesic request (minutes) (p-value: 0.064) or visual analog pain scale (p-value: &gt; 0.05). Incidence of complications was highly significant between the study groups (p-value: &lt; 0.001). Conclusions: To decrease postoperative opioid use with their multiple side effects and improve patient satisfaction scores in patients undergoing open heart surgery under general anesthesia, the use of either ketamine or dexmedetomidine is recommended in the postoperative period as an adjuvant modality and a good idea with observation of possibility of some preventable side effects.

Aim. To evaluate immediate and long-term oncological results ofsurgical treatment of recurrent rectal cancer involving the urinary tractsystem to show the need for a multidisciplinary treatment approach for locally advanced recurrent rectal cancer. Material and methods. Retrospective cohort analysis with prospective supported database. Analyzed 14 cases: all patients with locally advanced rectal cancer recurrence involving urinary tract system were operated at the Clinic of Coloproctology and Minimally Invasive Surgery in 2013-2022. Results. The age of the patients was 51.6 ± 13.0 years, 6 men, 8 women. The greatest recurrence number was (88%) finded in group of primary colorectal cancer of the lower and middle parts of the rectum. In 57.2% observations patients received preoperative chemotherapy or combination with radiotherapy. Approximately 64% of primary operations were performed using an open approach. Recurrence of CRC with pT3-T4 invasion was diagnosed in 72% of cases. Metastatic damage of lymphatic nodes after primary surgery were identified in 57.2% of cases. In 2 observations primary surgery was performed with R2 resection margin, relapse in that cases was detected after 11 and 13 months. One histopathological report indicated R1 resection, relapse noted after 6 months. Adjuvant chemotherapy was performed in 10 cases (71.4%), in two cases (14.3%) – postoperative radiation therapy. Average time for recurrence detecting after primary operation was 16.5 [12-28] months. Advanced combined interventions including recurrence removal with colon resection, gynecological and urological stages (RR+CR+GR+UR) amounted to 36%, recurrence removal with resection colon and urological stage (RR+CR+UR) was performed in 43% of cases, recurrence removal without the colonic stage (RR+GR+UR and RR+UR) - 3 (21%) patients. Reconstructive surgery to restore urine derivation were performed in 12 (85.7%) cases. The average duration of the procedures was 412.5[205-490] minutes, intraoperative blood loss - 275 [150-400] ml. Early postoperative complications are classified as Clavien-Dindo III. One patient with SIRS was classified as a complication Clavien-Dindo IV. The duration of the postoperative period was 25.5 [14-30] days. Postoperative mortality was 0%. According pathohistological examination R1 resection was detected in 3 (21.4%) cases. Adjuvant chemotherapy was performed 8 (57.1%) patients, in 1 case (7.1%) combination with a course of radiotherapy. During the period 24 months after surgery the mortality rate was 14.3%, repeated relapses diagnosed in 3 (21.4%) patients, one was reoperated. Distant metastases was noted in 4 (28.6%) patients, of which in 1 case with repeated recurrence. Discussion.

Introduction. Postoperative hernias occur in 10–15% of patients. Considering the increase in the incidence of complications with the number of operations it is crucial to choose the optimal surgical technique in order to control the complications rate. This literature review summarizes previous studies on the treatment of postoperative hernias with mesh, comparing complication and recurrence rates according to surgical technique and mesh position. Methods. A thorough search was conducted on the PubMed database to retrieve literature on recurrence, chronic pain, haematoma, seroma, and surgical site infections rates. The results were meticulously summarised and used to confidently compare open and laparoscopic surgical techniques, as well as “sublay” and “onlay/inlay” mesh positions in more than 5-year follow-up. Results. The analysis was conducted on five publications that met the selection criteria. The results showed that laparoscopically treated hernias had lower recurrence and chronic pain rates, but more frequent haematomas. The presence of wound infections, BMI &gt;30, treatment of recurrent postoperative hernias, multiple fascia lesions, enterotomy, larger abdominal wall defect and longer operative time were observed to be associated with higher recurrence rates. The position of the sublay mesh is associated with less frequent seromas, surgical infections, and recurrence compared to the onlay/inlay position. Studies have reported the superiority of large-pore lightweight polypropylene multifilament mesh over the same heavyweight mesh in managing postoperative hernias. Lightweight mesh is linked to a lower risk of hernia recurrence and higher compliance with the abdominal wall. Conclusion. Laparoscopic surgery is associated with lower rates of recurrence and chronic pain, but a higher frequency of haematomas. The sublay mesh position is associated with lower rates of seromas, surgical infections, and recurrence.

Comparison Between Surgical Techniques for Correction of Congenital Syndactyly: A Systematic Review and Meta Analysis

This review aimed to assess which surgical technique has better outcomes to correct one of the most common congenital anomalies of the upper limb: syndactyly. The following databases were used in the search: PubMed, Embase, Cochrane (CENTRAL), LILACS, SciELO, Scopus and Web of Science, on October 27, 2022. Studies that described a surgical technique for correcting syndactyly and evaluated surgical complications were included. Studies about noncongenital or foot syndactyly were excluded. The risk of bias was assessed using a specific method for case reports. For synthesis of results, the characteristics of the studies and techniques were demonstrated by a qualitative analysis. Meta-analysis models were applied for complications, functionality, and aesthetic. 73 studies were included, of which 70 were series or case reports, 27 studies did not use skin grafts and 7 studies used external fixators. To evaluate functional results, 42 studies used only the surgeon’s opinion. Meta-analyses showed a higher incidence of scar defects when using skin grafts and of infection when using external fixators. There was no difference for web creep and readmission. Few studies evaluated results using the VSS scale, showing worse scar pigmentation when skin grafts were used, but there was no difference in other parameters (PROSPERO CRD42022368930).

Tendón de Aquiles anatomía e insuficiencia

Introduction: the main aspects of Achilles tendon (AT) insufficiency were determined through the review of classic texts and current literature on the topic, to acquire the various conceptual and therapeutic tools in clinical practice. Methodology: we used the PubMed, Clinical Key, Embase, Cochrane and Lilacs search engines, including references in Spanish and English published between 1980 and 2020. Articles were reviewed using the CONSORT, STROBE or PRISMA guidelines, as appropriate. Results: 30 articles directly related to the topic were selected. Meta-analyses, systematic reviews, prospective and observational studies, and narrative reviews were included. Discussion: there is a wide spectrum of intrinsic and extrinsic predisposing risk factors for the development of AT insufficiency, but its etiology remains unclear. The mainstay treatment for tendinopathies in general, is rehabilitation provided by trained personnel. The surgical approach, by percutaneous or open surgical release techniques, is reserved for cases in which conservative approaches fail. Nonsurgical treatment for ruptured AT has shown excellent outcomes if patients undergo a strict rehabilitation process following diagnosis, however, in our socioeconomic context, tendon repair surgery continues to be a first-line therapeutic pillar. Conclusion: this review provides basic concepts and their correlation with biomechanics, indispensable for an early diagnosis and successful treatment.

Post–Liver Transplantation Vascular and Biliary Anatomy: A Pictorial Review

AbstractThis article aims to assist radiologists in navigating the vascular and biliary anatomy of post-transplant patients, thereby enhancing their diagnostic accuracy and determining the need for potential interventions. We have detailed established methods for anastomosis between the donor and recipient arterial, hepatic venous, portal venous, and biliary systems, while omitting surgical techniques, vascular shunting, and operative procedures, as our primary audience is radiologists. The focus of this review is on inflow and outflow of both blood and bile. Given the numerous possible anastomosis points in hepatic transplantation, familiarizing radiologists with these variations will support their efforts in identifying crucial structures in post-transplant patients.

Surgical techniques for cardiac procurement, preparation and perfusion using the Organ Care System

We provide an audio-visual step-by-step guide to the preparation of a donor heart for the application of normothermic, ex situ cardiac perfusion on the TransMedics Organ Care System using a heart donated after brain death. The use of the Organ Care System increases heart transplantation activity by enabling the utilization of hearts donated after circulatory death, the use of extended criteria grafts and the extension of out-of-body time, which can help overcome geographic or surgical barriers. Ex situ cardiac perfusion is a new technique and is therefore not yet routinely performed in many centres. However, it can be assumed that this technique will become more established and widespread in the future. Our video tutorial, which summarizes all important steps, can therefore be of benefit to surgical teams for planning, training or as a refresher.

Surgical treatment of graft infection combined with aortoesophageal fistula after TEVAR: a retrospective single-center, single-arm study

ObjectiveAortoesophageal fistula (AEF) secondary to thoracic aortic endovascular repair (TEVAR) is rare and fatal. The author reports the treatment methods and outcomes of 10 patients with a TEVAR graft infection and an aortoesophageal fistula.MethodA retrospective analysis was conducted on the clinical data of 10 patients who developed a secondary AEF and a graft infection after TEVAR from March 2018 to March 2024.ResultThe perioperative mortality rate was 70%. Two patients had TEVAR only and all died of bleeding and infection. Eight patients underwent open surgery, five died within 30 days, four of them died due to massive bleeding, the one patient died of a serious infection after surgery. Three patients recovered well and were discharged. One patient died of severe pneumonia 3 months after discharge, and two patients survived for 6 years and 3 months, respectively.ConclusionExtra-anatomical bypass reconstruction is feasible for treating graft infection combined with aortoesophageal fistula after TEVAR but related to bad outcomes in most of the patients. It is reserved for highly select patients and is performed at centers with experience with this procedure.
