Implementation of Robotic Exoscope in Minimally Invasive Corpectomy at Thoracolumbar Junction for the Treatment of Traumatic Spinal Cord Compression.

The development and diffusion of minimally invasive (MI) approaches have coincided with improvements in magnification systems. The exoscope will probably open a new era in new technologies in spinal surgery. This study reports a retrospective series of 19 thoracolumbar (T11-L2) burst fractures with anterior column failure and cord compression, treated with MI corpectomy and spinal decompression assisted by a three-dimensional high-definition exoscope (Video 1). Exclusion criteria were pathologic or osteoporotic fractures, multilevel fractures, and previous surgery at the site of the fracture. Three key indicators were recorded: surgical time, blood loss, and intraoperative complications. A questionnaire was administered to assess the users' exoscope experience with ergonomics, preparation, magnification, image definition, illumination, and user-friendliness, compared with the operative microscope. To the best of our knowledge, this is the first study reporting on exoscope-assisted MI corpectomy. This procedure permitted low blood loss and less surgical time without intraoperative complications. The exoscope offers clear advantages in terms of ergonomics, definition, and user-friendliness. Moreover, it is a suitable instrument for training and education, providing an opportunity for better interaction with other members of the surgical staff.

Delayed Repair of E2 Bile Duct Injury With Robotic Roux-en-Y Hepaticojejunostomy.

Bile duct injury is a rare complication in the modern era of minimally invasive laparoscopic and robotic surgery; however, it can lead to serious short- and long-term consequences. Repair of bile duct injury with Roux-en-Y hepaticojejunostomy is a technically complex operation, especially when undertaken laparoscopically. Newer robotic technology improves surgeon's dexterity for fine suturing tasks such as in creating a delicate hepaticojejunostomy, which overcomes technical limitations of conventional laparoscopic approach. As surgeons accumulate more experience in minimally invasive bile duct surgery for benign and malignant diseases, the accepted surgical approaches gradually transition from open to robotic technique. In this video, we describe our robotic technique for delayed repair of an E2 bile duct injury.

Subtrochanteric Osteotomy in Direct Anterior Approach Total Hip Arthroplasty for Crowe IV Dysplasia-Surgical Technique and Literature Review.

For Crowe IV dysplasia, the clinical efficacy and surgical technique of subtrochanteric osteotomy (SO) within the direct anterior approach total hip arthroplasty (DAA-THA) was a subject of debate. This study aimed to describe the surgical technique and clinical outcomes in 11 cases of SO in DAA-THA and to summarize the relevant literature on this topic. Between June 2016 and June 2023, we retrospectively evaluated patients diagnosed with Crowe IV hip dysplasia at our institution. Criteria identified 11 patients who underwent SO during DAA-THA. Comprehensive data encompassing demographic information, radiological data, prosthetic implant type, and surgical intricacies were collected. In addition, an exhaustive review of existing case series literature was undertaken utilizing the PubMed databases. There were no revisions, deaths, dislocations, or infections. One hip (9.09%) had an intraoperative proximal split fracture, two hips (18.2%) had lower limb deep vein thrombosis, and one hip (9.09%) had symptoms of femoral nerve injury. Radiological data showed improved bilateral femoral offset, leg length discrepancy, and anatomical acetabular. During the mean follow-up of 2.18(1.06-2.46) years, patients demonstrated enhanced functional outcomes, with average changes of 25.2 in the Harris hip score and 47 in the WOMAC score. Reviewing the literature, most studies have favored S-ROM prostheses and transverse osteotomy techniques. Intraoperative fractures were notably frequent, with rates peaking at 25%. Nonunion and nerve injury were secondary common complications. SO via DAA-THA may offer satisfactory clinical and radiographic outcomes, but the literature review underscores the need for heightened awareness of intraoperative fracture risk. Proximal detachment of the vastus intermedius plays a pivotal role in SO exposure through the DAA.

Incidence of Complications and Revision Surgery After High Tibial Osteotomy: A Systematic Review.

BACKGROUND: High tibial osteotomy (HTO) is a well-recognized procedure for its effectiveness in treating symptomatic early knee arthritis and malalignment. Although there are numerous systematic reviews evaluating the management and outcomes after HTO, there are few investigations on complications of this procedure. PURPOSE: To systematically review the literature to determine the incidence of intraoperative and postoperative complications associated with medial opening wedge and lateral closing wedge HTOs. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: The Cochrane Database of Systematic Reviews, PubMed, Embase, and MEDLINE databases were queried for studies reporting complications associated with HTO with or without concomitant procedures. Data including patient characteristics, procedure type, concomitant procedures, follow-up time, and postoperative imaging were extracted. Rates of intra- and postoperative complications, reoperations, and conversion to arthroplasty were recorded. RESULTS: A total of 71 studies were included for analysis, comprising 7836 patients. The overall intraoperative complication rate during HTO was 5.5% (range, 0%-29.3%), and the overall postoperative complication rate was 6.9% (range, 0%-26.6%). The most common intraoperative complication was lateral hinge fracture (incidence, 9.1%; range, 0%-30.4%) in medially based HTOs and peroneal nerve injury in laterally based HTOs (incidence, 3.2%; range, 0%-8.7%). The overall incidence of neurovascular injury after medially or laterally based HTOs was 1.1% (range, 0%-18.9%). The most common postoperative complication was superficial infection (incidence, 2.2%; range, 0%-13%). Of the included studies, 62 included postoperative radiographic analysis, and among those, the incidence of nonunion was 1.9% (range, 0%-15.5%), loss of correction was 1.2% (range, 0%-34.3%), and implant failure was 1.0% (range, 0%-10.2%). Among studies reporting revision surgeries, the overall reoperation rate was 15.5% (range, 0%-70.7%), with the most common type of reoperation being hardware removal (incidence, 10.0%; range, 0%-60%). CONCLUSION: Intraoperatively, medially based HTOs are associated with a 1 in 11 risk of lateral hinge fracture and laterally based HTOs with a 1 in 30 risk of peroneal nerve injury. Postoperative complication rates in the range of 10% to 15% can be expected, including infection (2.9%), loss of correction (1.2%), and nonunion (1.9%). Patients should also be counseled that the reoperation rate is approximately 15%, with hardware removal being the most common procedure.

Systematic review of robotic ventral hernia repair with meta-analysis.

BACKGROUND: Despite being one of the most common operations performed by general surgeons, there is a lack of consensus regarding the recommended approach for ventral hernia repair (VHR). Recent times have seen the rapid development of new techniques, such as robotic ventral hernia repair (RVHR). This systematic review and meta-analysis aims to evaluate the currently available evidence relating to RVHR, in comparison to open VHR (OVHR) and laparoscopic VHR (LVHR). METHODS: A systematic search of the following databases was conducted: PubMed, Embase, Scopus and Web of Science. A meta-analysis was performed for the outcomes of length of stay (LOS), recurrence, operative time, intraoperative complications, wound complications, 30-day readmission, 30-day reoperation, mortality and costs. RESULTS: A total of 39 studies met inclusion criteria. Overall, RVHR reduced LOS, intra-operative complications, wound complications and readmission compared to OVHR. Compared to LVHR, RVHR was associated with increased operative time and costs, with comparable clinical outcomes. CONCLUSION: There is currently a lack of robust evidence to support the robotic approach in VHR. It does not demonstrate major benefits in comparison to LVHR, which is more affordable and accessible. Strong quality, long-term data is required to help with establishing a gold standard approach in VHR.

Robot-assisted laparoscopy does not have demonstrable advantages over conventional laparoscopy in endometriosis surgery: a systematic review and meta-analysis.

BACKGROUND: Endometriosis is a chronic condition affecting 6-10% of women of reproductive age, with endometriosis-related pain and infertility being the leading symptoms. Currently, the gold standard treatment approach to surgery is conventional laparoscopy (CL); however, the increasing availability of robot-assisted surgery is projected as a competitor of CL. This study aimed to compare the perioperative outcomes of robot-assisted laparoscopy (RAL) and CL in endometriosis surgery. OBJECTIVES: We aimed to compare the effectiveness and safety of these two procedures. METHODS: A systematic search was conducted in three medical databases. Studies investigating different perioperative outcomes of endometriosis-related surgeries were included. Results are presented as odds ratios (OR) or mean differences (MD) with 95% confidence intervals (CI). RESULTS: Our search yielded 2,014 records, of which 13 were eligible for data extraction. No significant differences were detected between the CL and RAL groups in terms of intraoperative complications (OR = 1.07, CI 0.43-2.63), postoperative complications (OR = 1.3, CI 0.73-2.32), number of conversions to open surgery (OR = 1.34, CI 0.76-2.37), length of hospital stays (MD = 0.12, CI 0.33-0.57), blood loss (MD = 16.73, CI 4.18-37.63) or number of rehospitalizations (OR = 0.95, CI 0.13-6.75). In terms of operative times (MD = 28.09 min, CI 11.59-44.59) and operating room times (MD = 51.39 min, CI 15.07-87.72;), the RAL technique remained inferior. CONCLUSION: RAL does not have statistically demonstrable advantages over CL in terms of perioperative outcomes for endometriosis-related surgery.

Nephrectomy in 52 dogs for the treatment of Dioctophyme renale infection - Knowing the enemy to win.

Dioctophyme renale (D. renale) is a nematode that parasitizes the kidney of mammals. Treatment is often surgical, with removal of the affected organ. This retrospective study aims to evaluate the epidemiological, clinical, and surgical aspects, the interval between diagnosis and treatment, the occurrence of pre- and intraoperative complications, and the postoperative survival time of dogs parasitized by D. renale undergoing therapeutic nephrectomy. Records of fifty-two dogs treated in a single hospital service were analyzed. We collected epidemiological data, laboratory results, diagnostic method, anesthetic protocol, surgical technique and time, type of antimicrobial prophylaxis, pre- and intraoperative complications, location and number of parasites, and postoperative survival time. Of the 52 dogs undergoing right nephrectomy by laparotomy, 61.5 % were female and 63.4 % were adults. Although the most common clinical sign was hematuria (25 %), 61.5 % of the patients were asymptomatic. Eosinophilia and increased serum urea were the only laboratory changes found. The interval between diagnosis and surgery was 27.4 ± 23 days and no patient showed changes suggestive of surgical emergency. The most common surgical approach was the right paracostal (61.5 %), and a continuous suture pattern was predominant. Intraoperative complications occurred in 9.6 % of the procedures, varying from mild to severe hemorrhage. Mean postoperative survival was 835.5 ± 428 days. Dioctophymosis was effectively controlled by nephrectomy of the affected kidney, allowing a mean survival of more than 830 days. No serious complications caused by intervals between diagnosis and treatment have been reported. This is the largest retrospective study evaluating dogs infected with D. renale that were surgically treated.

How to Recognize, Correct, and Avoid Intraoperative Complications During Anterior Cruciate Ligament Reconstructions.

Technical complications are a leading cause of graft failure following anterior cruciate ligament reconstructions. Complications can occur during any phase of the procedure, from graft harvesting to tunnel preparation to graft fixation. Predicting potential causes of technical difficulty and developing strategies to avoid potential pitfalls can limit the number of intraoperative complications. If adverse events do occur intraoperatively, prompt recognition and treatment can lead to favorable outcomes. It is important to discuss strategies to understand potential complications and develop tactics to avoid and correct adverse events that can occur during anterior cruciate ligament reconstruction.

Outcome of simultaneous bi-unicompartmental knee arthroplasty: a systematic review.

BACKGROUND AND AIM: Simultaneous medial and lateral tibiofemoral osteoarthritis (OA) could be treated with bi-unicompartmental knee arthroplasty (Bi-UKA) as an alternative to total knee arthroplasty (TKA). The present systematic review aims to assess if simultaneous Bi-UKA is a feasible option for treating medial and lateral tibiofemoral OA. MATERIALS AND METHODS: A comprehensive search of PubMed, MEDLINE, Cochrane Library, and Google Scholar was performed to find studies that reported on the outcome of simultaneous Bi-UKA for both medial and lateral tibiofemoral OA. RESULTS: Seven studies were considered eligible for inclusion in the present systematic review. Intraoperative fractures occurred 8 times. Overall, there were 22 revisions of the prosthetic components for any reason with a survival rate that ranged from 83 to 100%. Of these, 16 revisions were for the aseptic loosening of the prosthetic components. Out of 302 surgeries, three were revised due to symptomatic OA progression in the patello-femoral joint. All clinical scores improved at the latest follow-up compared to preoperative values. Moreover, there were no differences in clinical scores of Bi-UKA compared to unicompartmental knee arthroplasty (UKA), or medial UKA plus patello-femoral prosthesis. Whereas, compared to TKA, Bi-UKA patients had comparable or superior scores. Finally, the Bi-UKA group had a significantly shorter hospital stay compared to the TKA group. CONCLUSIONS: The use of simultaneous Bi-UKA is a valid option to address bicompartmental knee OA in selected patients with low intraoperative fracture rate, low revision rate, satisfactory clinical outcome, and fast recovery.

Outcomes associated with peripartum hysterectomy in the setting of placenta accreta spectrum disorder.

BACKGROUND: Although peripartum hysterectomy for placenta accreta spectrum disorder is known to be associated with complications at the time of delivery, there are limited data on postpartum outcomes and readmission risk in this population. OBJECTIVE: This study aimed to analyze risks for adverse outcomes and postpartum readmissions in the setting of peripartum hysterectomy for placenta accreta spectrum disorder by severity of placenta accreta spectrum disorder subcategory. STUDY DESIGN: Using the 2016-2020 Nationwide Readmissions Database, this retrospective cohort study identified peripartum hysterectomies with a diagnosis of placenta accreta spectrum disorder. The primary exposure was placenta accreta spectrum disorder, subcategorized as placenta accreta vs increta/percreta. The primary outcome was readmission rate and delivery complications. Complications evaluated included the following: (1) nontransfusion severe maternal morbidity (ntSMM), (2) venous thromboembolism, (3) reoperation, (4) intraoperative complications, (5) hemorrhage, (6) sepsis, and (7) surgical site complications. We additionally evaluated delivery hospitalization and readmission mean length of stay, and hospital costs. Unadjusted and adjusted logistic regression models were fit for outcomes adjusting for clinical, demographic, and hospital factors. The association measures were expressed as unadjusted and adjusted odds ratios with 95% confidence intervals. RESULTS: Between 2016 and 2020, 7864 hysterectomies during a delivery hospitalization with a diagnosis of placenta accreta spectrum disorder were identified (66.5% with placenta accreta and 33.5% with placenta increta/percreta diagnoses). The overall 60-day all-cause readmission rate was 7.3%. Most readmissions (57.2%) occurred within 10 days of hospital discharge. Compared with peripartum hysterectomy with a diagnosis of placenta accreta, hysterectomies with placenta increta/percreta diagnoses carried significantly increased risk of 60-day readmission (adjusted odds ratio, 1.31; 95% confidence interval, 1.01-1.71), inpatient mortality (odds ratio, 13.23; 95% confidence interval, 3.35-52.30), nontransfusion severe maternal morbidity (adjusted odds ratio, 1.43; 95% confidence interval, 1.20-1.71), intraoperative complications (adjusted odds ratio, 2.31; 95% confidence interval, 1.93-2.77), and surgical site complications (adjusted odds ratio, 1.55; 95% confidence interval, 1.23-1.95). The median length of stay during delivery hospitalization was longer for placenta increta/percreta (5.8 days; 95% confidence interval, 5.4-6.1) than for placenta accreta (4.2 days; 95% confidence interval, 4.1-4.3; P<.05). In addition, delivery hospitalization costs were higher in cases of placenta increta/percreta (median, $30,686; 95% confidence interval, $28,922-$32,449) than placenta accreta (median, $21,321; 95% confidence interval, $20,480-$22,163). CONCLUSION: Complication and readmission risks after peripartum hysterectomy with placenta accreta spectrum disorder are high. Compared with patients with placenta accreta, patients with placenta increta/percreta had increased risk for delivery and postoperative complications and postpartum readmission, and increased costs and length of stay.

¿Podemos reducir las complicaciones de doble J en el paciente pediátrico? / Can double J stent complications be reduced in pediatric patients?

Objetivos: El uso de catéteres doble J (DJ) es un proceso frecuenteen uropediatría, pero no exento de morbilidad. El objetivo de nuestroestudio es describir factores de riesgo (FR) de complicación de losDJ en pacientes pediátricos y comprobar la calidad de la informacióntransmitida a las familias en relación al catéter. Material y métodos: Estudio retrospectivo de pacientes intervenidos en urología con colocación de DJ (2017–2022). Grupos a estudio: complicados (CC) y no complicados (SC). Realizamos un análisismultivariante para identificar FR relacionados con complicaciones yun análisis de calidad percibida por las familias mediante encuesta desatisfacción (0 no satisfacción, 10 máxima satisfacción).Resultados. Incluimos 180 pacientes, (236 DJ). Diagnósticos principales: trasplante renal 29,8%, estenosis pieloureteral 26%, y urolitiasis20,7%. La tasa de complicaciones fue del 21,9%, con un ComprehensiveComplication Index (CCI) medio de 26,8. La antibioterapia profilácticano se relaciona con menos complicaciones (97,3% vs 98,1% p= 0,727). FR de complicación: acumular más de un catéter (p< 0,001, OR 6,628)o la colocación bilateral (p< 0,05; OR 4,871). Un mal registro en lahistoria clínica se relacionó con más complicaciones (p= 0,025). Enla encuesta de calidad de información recibida, el 20% reflejaron unapuntuación inferior a 7/10. Conclusiones: La morbilidad asociada al DJ se relaciona con suduración, la bilateralidad o acumular más de un catéter. Su adecuadoregistro en la historia clínica se relaciona con menor duración del mismo y, por tanto, menos complicaciones. La profilaxis antibiótica no hademostrado disminuir las complicaciones, su uso rutinario debe serrevalorado.(AU)

Objective: The use of double J (DJ) stents is frequent in urologicalpediatrics, but it is not exempt from morbidity. The objective of this studywas to describe the risk factors (RF) of DJ complications in pediatricpatients, and to analyze the quality of the information provided to thefamilies with respect to the stent.Materials and methods: A retrospective study of patients undergoing surgery with DJ placement in the urology department from 2017to 2022 was carried out. Study patients were divided into two groups –complicated (C) and non-complicated (NC). A multivariate analysis wasperformed to identify complication-related RFs, and a quality analysisas perceived by the families was conducted by means of a satisfactionsurvey (0 = total dissatisfaction; 10 = maximum satisfaction). Results: 180 patients were included (236 DJs). The main diagnosesincluded renal transplantation (29.8%), ureteropelvic stenosis (26%), andurolithiasis (20.7%). Complication rate was 21.9%, with a mean comprehensive complication index (CCI) of 26.8. Prophylactic antibiotic therapywas not associated with fewer complications (97.3% vs. 98.1%; p=0.727). Complication RFs included more than one stent (p<0.001; OR=6.628)and bilateral placement (p<0.05; OR=4.871). Poor registration in themedical records was associated with greater complications (p=0.025). Inthe information quality survey, 20% reported a score lower than 7/10.Conclusions: DJ-associated morbidity has a direct relationshipwith DJ duration, bilaterality, and carrying more than one stent in alifetime. Adequate registration in the medical records is associatedwith shorter DJ duration, and therefore, fewer complications. Antibiotic prophylaxis did not reduce complications, which means its routineuse should be reconsidered.(AU)

Managing Complications Related to Peripheral Nerve Surgery: Selected Illustrative Cases.

Peripheral nerve surgery mostly involves elective procedures; thus, the associated complications are of great clinical, social, and medicolegal importance. Apart from the general perioperative morbidity, complications during interventions on peripheral nerves are extremely rare. However, iatrogenic peripheral nerve injuries during unrelated surgical procedures performed by those not specialised in peripheral nerve surgery remain the most significant group of complications, accounting for up to approximately 17% of all cases. The aims of this review are to provide better insight into the multifaceted nature of complications related to peripheral nerve surgery-from the perspective of their causes, treatment, and outcome-and to raise surgeons' awareness of the risks of such morbidity. It should be emphasized that intraoperative complications in peripheral nerve surgery are largely "surgeon-related" rather than "surgery-related"; therefore, they have great potential to be avoided.

Risk factors for intraoperative complications, postoperative complications, and prolonged length of stay after laparoscopic adrenalectomy by transperitoneal lateral approach: a retrospective cohort study of 547 procedures.

BACKGROUND: Laparoscopic adrenalectomy (LA) is the gold standard for the resection of most adrenal lesions. A precise delineation of factors influencing its outcomes is lacking. The aim of this study was to assess factors associated with intraoperative complications, postoperative complications, and prolonged length of stay (LOS) after LA. METHODS: Patients who underwent LA from 1999 to 2021 in a single-academic-institution were included. Patient and disease-specific data, intraoperative complications, postoperative complications according to Dindo-Clavien (DC) scale, and LOS were recorded. Predictive factors of complications and prolonged LOS were determined by logistic regression. RESULTS: We identified 530 patients who underwent 547 LA. Intraoperative complications occurred in 33 patients (6.0%). Postoperative complications ≥  DC grade 2 occurred in 73 patients (13.35%); severe postoperative complications ≥ DC grade 3 in 14 patients (2.56%). Postoperative complications were positively associated with age ≥ 72 (OR 1.14 [95% CI 1.02-1.29]), intraoperative complications (OR 1.36 [95% CI 1.14-1.63]), and negatively associated with non functional adenomas (OR 0.88 [95% CI 0.7-0.99]), and right adrenalectomy (OR 0.91 [95% CI 0.86-0.97]). Severe postoperative complications were positively associated with chronic obstructive pulmonary disease (COPD, OR 1.08 [95% CI 1.00-1.17]), and negatively associated with right adrenalectomy (OR 0.97 [95% CI 0.92-0.99]). Prolonged LOS was associated with age ≥ 72 (OR 1.21 [95% CI 1.05-1.41]), and COPD (OR 1.20 [95% CI 1.01-1.44]). CONCLUSIONS: LA remains safe when performed by surgeons with expertise. Right adrenalectomy resulted in less postoperative overall and severe complications. The risk-benefit equation should be carefully assessed before left LA in older patients with COPD.

Pielonefritis xantogranulomatosa: un reto actual para la laparoscopia.

OBJECTIVE: To present the results of our case series on laparoscopic nephrectomy in xanthogranulomatous pyelonephritis (XGP). METHODS: A retrospective study was conducted that included 143 patients treated with laparoscopic nephrectomy for non-functioning kidney, of whom 15 had XGP, within the time frame of 2011 to 2019. The demographic and clinical data were collected, along with the intraoperative results, complications, and days of hospital stay. RESULTS: Transperitoneal laparoscopic nephrectomy was successfully performed on 15 patients with XGP, with no need for conversion. Mean intraoperative time was 124.4 minutes (range 70-240) and intraoperative blood loss was 148.5 ml (range 30-550), with no blood transfusion required. No intraoperative complications occurred but there was one postoperative complication (6.6%), classified as Clavien-Dindo I (surgical wound infection). Mean hospital stay was 2.85 days (range 2-7). CONCLUSIONS: Nephrectomy is the definitive management for XGP, and the laparoscopic approach should be considered a treatment modality, despite the fact that the pathology involves a severe chronic inflammatory process. Its benefits are reduced surgery duration, less blood loss, a lower complication rate, and fewer days of hospital stay, when performed by a skilled and experienced surgeon.

OBJETIVO: Presentar los resultados de nuestra serie de nefrectomía laparoscópica en pielonefritis xantogranulomatosa (PXG). MÉTODO: Se realizó un estudio retrospectivo que incluyó 143 pacientes tratados con nefrectomía laparoscópica por exclusión renal, de los cuales 15 fueron por PXG, en el periodo comprendido de 2011 a 2019. Se recolectaron datos demográficos y clínicos, resultados transoperatorios, complicaciones y días de estancia hospitalaria. RESULTADOS: Se realizó nefrectomía laparoscópica transperitoneal de forma exitosa en 15 pacientes con PXG, sin necesidad de conversión. El tiempo transoperatorio promedio fue de 124.4 minutos (rango: 70-240). El sangrado transoperatorio fue de 148.5 ml (rango: 30-550), sin requerimiento de transfusión sanguínea. No se reportaron complicaciones transoperatorias; se presentó una complicación en el posoperatorio (6.6%) clasificada como Clavien-Dindo I (infección de la herida quirúrgica). La estancia hospitalaria promedio fue de 2.85 días (rango: 2-7). CONCLUSIONES: El manejo definitivo de la PXG es la nefrectomía, y el abordaje laparoscópico debe ser considerado como una modalidad de tratamiento a pesar de ser una patología que presenta un proceso inflamatorio grave y crónico, obteniéndose beneficios como disminución en el tiempo quirúrgico, menor sangrado, menor tasa de complicaciones y menos días de estancia hospitalaria cuando es realizado por un cirujano experimentado.

Intraoperative complications during standard and complex endovascular aortic repair.

This study aimed to provide a comprehensive overview of the most common intraoperative adverse events that occur during standard endovascular repair and fenestrated-branched endovascular repair to treat abdominal aortic aneurysms, thoracoabdominal aortic aneurysms, and aortic arch aneurysms. Despite advancements in endovascular techniques, sophisticated imaging and improved graft designs, intraoperative difficulties still occur, even in highly standardized procedures and high-volume centers. This study emphasized that with the increased adoption and complexity of endovascular aortic procedures, strategies to minimize intraoperative adverse events should be protocolized and standardized. There is a need for robust evidence on this topic, which could potentially optimize treatment outcomes and durability of the available techniques.

Laparoscopic Radical Nephrectomy with Transperitoneal Approach for Large Renal Tumors: Standardized Surgical Technique and Outcomes.

Background: Minimally invasive surgery is used only in selected cases of renal masses greater than 7 cm, and few studies exist in this setting. This study aimed to evaluate the safety and effectiveness of a laparoscopic surgical approach for the treatment of large renal tumors using a standardized technique. Materials and Methods: Data of patients who underwent laparoscopic nephrectomy (LN) using the transperitoneal approach were retrospectively evaluated from December 2019 to September 2022. The study population was divided into two groups: patients with renal masses <7 cm (Group A) and those with renal masses ≥7 cm in diameter (Group B). The intraoperative and postoperative outcomes were compared. Results: Forty patients were enrolled (16 in Group A and 24 in Group B) in this study. Although significant difference in terms of age and American Society of Anesthesiologists score were detected, the two groups did not differ in mean operative time (130 minutes standard deviation [SD] ± 64 versus 148 minutes DS ± 56; P = .376), intraoperative complications (0% versus 8.3%; P = .508), need for postoperative transfusion (12% versus 12%; P > .999), and length of stay (3.38 DS ± 0.62 days versus 3.92 DS ± 2.47; P = .313). One patient had a local recurrence and died ∼13 months after surgery. Furthermore, 2 patients developed trocar-site incisional hernia in Group B. Conclusion: In this cohort of patients, LN for large renal tumors appeared to be safe and feasible. Larger mass dimension does not appear to influence the outcomes when the surgery is performed using a standardized technique by experienced surgeons.
