Hospital policy of tranexamic acid to reduce transfusion in major non-cardiac surgery (TRACTION): protocol for a phase IV randomised controlled trial.

INTRODUCTION: Tranexamic acid (TXA) is an inexpensive and widely available medication that reduces blood loss and red blood cell (RBC) transfusion in cardiac and orthopaedic surgeries. While the use of TXA in these surgeries is routine, its efficacy and safety in other surgeries, including oncologic surgeries, with comparable rates of transfusion are uncertain. Our primary objective is to evaluate whether a hospital-level policy implementation of routine TXA use in patients undergoing major non-cardiac surgery reduces RBC transfusion without increasing thrombotic risk. METHODS AND ANALYSIS: A pragmatic, registry-based, blinded, cluster-crossover randomised controlled trial at 10 Canadian sites, enrolling patients undergoing non-cardiac surgeries at high risk for RBC transfusion. Sites are randomised in 4-week intervals to a hospital policy of intraoperative TXA or matching placebo. TXA is administered as 1 g at skin incision, followed by an additional 1 g prior to skin closure. Coprimary outcomes are (1) effectiveness, evaluated as the proportion of patients transfused RBCs during hospital admission and (2) safety, evaluated as the proportion of patients diagnosed with venous thromboembolism within 90 days. Secondary outcomes include: (1) transfusion: number of RBC units transfused (both at a hospital and patient level); (2) safety: in-hospital diagnoses of myocardial infarction, stroke, deep vein thrombosis or pulmonary embolism; (3) clinical: hospital length of stay, intensive care unit admission, hospital survival, 90-day survival and the number of days alive and out of hospital to day 30; and (4) compliance: the proportion of enrolled patients who receive a minimum of one dose of the study intervention. ETHICS AND DISSEMINATION: Institutional research ethics board approval has been obtained at all sites. At the completion of the trial, a plain language summary of the results will be posted on the trial website and distributed in the lay press. Our trial results will be published in a peer-reviewed scientific journal. TRIAL REGISTRATION NUMBER: NCT04803747.

Maximum surgical blood ordering schedule for elective surgical procedures in Omdurman teaching hospital, Sudan.

BACKGROUND: The need for blood during a surgical procedure is greater than what blood banks are able to provide. There is an excessive amount of blood being ordered for elective surgeries, surpassing the actual requirements. Only 30% of the cross matched blood is actually used in these surgeries. The accuracy of estimating the transfusion needs before a surgical procedure can be determined by looking at the cross match to transfusion ratio and the transfusion index. "These indicators play a crucial role in developing the maximum surgical blood ordering schedule; in this study, these indicators were tested." AIM OF STUDY: Is to determine the efficiency of blood ordering and transfusion practices for patients undergoing elective surgeries. METHODS: This study is a prospective cross-sectional hospital-based study done at Omdurman Teaching Hospital-Sudan. Conducted for the duration of 6 months period from July to December 2019.The study participants were patients who underwent elective surgical procedures in general surgery and Urology departments as total coverage sample over a period of study duration. Ethical clearance obtained from ethical committee of Sudan Medical Specialization Board. RESULTS: Two hundreds seven patients included in this study, the amount of blood units requested were 443-unit, cross matching for 98.6% (n 437) of units were done. Only 100 unit were Transfused (22,8%). The calculated CT ratio was 4.4, transfusion index was 1.6 and transfusion probability was 29.9%. CONCLUSION: Transfusion probability and transfusion index of the present study were optimal but comparatively higher than the standard guidelines as most of the cross matched blood was not utilized.

The application of a single-hand-operated hepatic pedicle clamping clamp in laparoscopic hepatectomy.

OBJECTIVE: In this paper, a single-hand-operated hepatic pedicle clamp was introduced, and its application value in laparoscopic liver tumor resection was preliminarily discussed. METHODS: The clinical data of 67 patients who underwent laparoscopic liver tumor resection at the First Affiliated Hospital of Wannan Medical College from March 2019 to October 2023 were retrospectively analyzed. The Pringle maneuver was performed with a hepatic pedicle clamp during the operation. The preoperative, intraoperative and postoperative clinical data were observed and recorded. RESULTS: Sixty-seven patients had a median block number, block time, intraoperative blood loss, and postoperative length of hospital stay of 4, 55 min, 400 ml, and 7 days, respectively. The average operation time was 304.9±118.4 min, the time required for each block was 3.2±2.4 s, and the time required for each removed block was 2.6±0.7 s. None of the patients developed portal vein thrombosis or hepatic artery aneurysm formation. CONCLUSION: The hepatic pedicle clamping clamp is simple to use in laparoscopic hepatectomy, optimizes the operation process, and has a reliable blocking effect. It is recommended for clinical application.

Advantages of robot-assisted resection of large mediastinal tumors: a single-center preliminary study.

Current study aims to assess the safety and efficacy of robot-assisted thoracoscopic surgery (RATS) for sizable mediastinal masses with a minimum diameter ≥6 cm, compared with video-assisted thoracoscopic surgery (VATS) and open surgery. This study enrolled 130 patients with mediastinal tumors with no less than 6 cm diameter in Zhongnan Hospital, Wuhan University, including 33 patients who underwent RATS, 52 patients who underwent VATS and 45 patients who underwent open surgery. After classifying based on mass size and whether it has invaded or not, we compared their clinical characteristics and perioperative outcomes. There was no significant difference in age, gender, mass size, myasthenia gravis, mass location, pathological types (p > 0.05) in three groups. Patients undergoing open surgery typically presenting at a more advanced stage (p < 0.05). No obvious difference was discovered in the average postoperative length of stay, operation duration, chest tube duration and average postoperative day 1 drainage output between RATS group and VATS group (p > 0.05), while intraoperative blood loss in RATS group was significantly lower than VATS group (p = 0.046). Moreover, the postoperative length of stay, operation duration, chest tube duration and intraoperative blood loss in RATS group were significantly lower than open surgery group (p < 0.001). RATS is a secure and efficient approach for removing large mediastinal masses at early postoperative period. In comparison with VATS, RATS is associated with lower intraoperative blood loss. Compared with open surgery, RATS is also associated with shorter postoperative length of stay, operation duration, chest tube duration and intraoperative blood loss.

Retrospective comparative clinical study on clinical effect of suture micromarsupialization on ranula.

OBJECTIVES: This study aimed to evaluate the clinical effect of suture micromarsupialisation on ranula.  Methods: This is a retrospective comparative clinical study, the clinical data of 106 patients with simple ranula admitted to the Oral and Maxillofacial Surgery Department of Beijing Zhongguancun Hospital between August 2022 and May 2023 were collected. The patients were divided into the research group (55 patients), who underwent suture micromarsupialisation, and control group (51 patients), who underwent ranula resections. The therapeutic methods were compared regarding cure rate, surgical duration, intraoperative blood loss, 24-h postoperative pain score, intraoperative and postoperative complications, and recurrence rate.  Results: The difference in the total effective rate between the two groups was not statistically significant (98.18% vs. 96.08%, χ2 = 2.116, p = 0.347). Intraoperative blood loss (4.35 ± 1.19 vs. 26.33 ± 3.19), surgery duration (6.33 ± 1.43 vs. 26.33 ± 3.19) and the postoperative visual analogue scale score (0.32 ± 0.03 vs. 3.81 ± 0.15) in the research group were lower than in the control group (p < 0.05). The incidence rate of complications in the research group was lower than in the control group (7.27% vs. 25.49%, χ2 = 6.522, p = 0.011). The difference in the postoperative recurrence rate between the two groups was not statistically significant (3.63% vs. 9.80%, χ2 = 1.632, p = 0.201).  Conclusions: Suture micromarsupialisation is a conservative therapeutic method for intraoral ranula. The cure rate of suture micromarsupialisation is similar to that of traditional surgery. It is recommended to use this technique as a first-line conservative therapeutic method for intraoral ranula, as it has the advantages of minimal invasion, simple operation, no pain, no need for haemostasis and no complications.

Robotic versus laparoscopic anterior resection for the treatment of stage II and III sigmoid colon cancer: a propensity score-matched analysis.

Robot-assisted laparoscopic anterior resection is a novel technique. However, evidence in the literature regarding the advantages of robot-assisted laparoscopic surgery (RLS) is insufficient. The aim of this study was to compare the outcomes of RLS versus conventional laparoscopic surgery (CLS) for the treatment of sigmoid colon cancer. We performed a retrospective study at the Northern Jiangsu People's Hospital. Patients diagnosed with sigmoid colon cancer and underwent anterior resection between January 2019 to September 2023 were included in the study. We compared the basic characteristics of the patients and the short-term and long-term outcomes of patients in the two groups. A total of 452 patients were included. Based on propensity score matching, 212 patients (RLS, n = 106; CLS, n = 106) were included. The baseline data in RLS group was comparable to that in CLS group. Compared with CLS group, RLS group exhibited less estimated blood loss (P = 0.015), more harvested lymph nodes (P = 0.005), longer operation time (P < 0.001) and higher total hospitalization costs (P < 0.001). Meanwhile, there were no significant differences in other perioperative or pathologic outcomes between the two groups. For 3-year prognosis, overall survival rates were 92.5% in the RLS group and 90.6% in the CLS group (HR 0.700, 95% CI 0.276-1.774, P = 0.452); disease-free survival rates were 91.5% in the RLS group and 87.7% in the CLS group (HR 0.613, 95% CI 0.262-1.435, P = 0.259). Compared with CLS, RLS for sigmoid colon cancer was found to be associated with a higher number of lymph nodes harvested, similar perioperative outcomes and long-term survival outcomes. High total hospitalization costs of RLS did not translate into better long-term oncology outcomes.

Hidden blood loss and the influential factors after minimally invasive treatment of posterior pelvic ring injury with sacroiliac screw.

BACKGROUND: To analyze the perioperative bleeding and hidden blood loss (HBL) of sacroiliac screw minimally invasive treatment of pelvic posterior ring injury and explore the influential factors of HBL after operation for providing reference for clinical treatment. METHOD: A retrospective analysis was conducted on data from 369 patients with posterior pelvic ring injuries treated with sacroiliac screws internal fixation at our hospital from January 2015 to January 2022. The research was registered in the Chinese Clinical Trial Registry in July 2022 (ChiCTR2200061866). The total blood loss (TBL) and HBL of patients were counted, and the factors such as gender, age, and surgical duration were statistically analyzed. The influential factors of HBL were analyzed by multiple linear regression. RESULTS: The TBL was 417.96 ± 98.05 ml, of which the visible blood loss (VBL) was 37.00 ± 9.0 ml and the HBL was 380.96 ± 68.8 ml. The HBL accounted for 91.14 ± 7.36% of the TBL. Gender, surgical duration, fixed position, and fixed depth had significant effects on the HBL (P < 0.05). CONCLUSIONS: The HBL was the main cause of anemia after minimally invasive treatment of posterior pelvic ring injury with a sacroiliac screw. Gender, surgical duration, fixed position, and fixed depth were closely related to the occurrence of HBL. In clinical treatment, we should consider these influential factors and take effective measures to reduce the impact of HBL on patients.

Predictors of Blood Transfusion in Patients Undergoing Cytoreductive Surgeries for Ovarian Malignancy.

OBJECTIVES: The aims of this study were to describe the baseline estimated blood loss (EBL) in surgery and transfusion rate in patients undergoing cytoreductive surgeries for ovarian malignancy, and identify perioperative variables associated with blood loss and transfusion. METHODS: A retrospective cohort study at a single institution was performed that included patients with known or suspected ovarian malignancy undergoing cytoreductive surgery between 2016 and 2021. t tests, χ2 tests, and multiple logistic regression analyses were used. RESULTS: Among 44 patients meeting inclusion criteria, 61% received perioperative blood transfusion. There were significant differences in EBL and preoperative hemoglobin levels between patients who did and did not receive transfusion (EBL 442.6 vs 236.8 mL, P = 0.0008; preoperative hemoglobin 10.2 vs 11.2 g/dL, P = 0.049). After adjusting for preoperative hemoglobin, the risk of transfusion increased for each additional 200 mL of EBL (odds ratio [OR] 3.8, 95% confidence interval [CI] 1.5-9.5). Stratified by race, the association between EBL and transfusion risk remained statistically significant only for non-Latinx White patients (OR 6.1, 95% CI 1.7-21.9), who made up 77% of the study population, but not for patients of other races and ethnicities (OR 1.0, 95% CI 0.16-6.42). CONCLUSIONS: Perioperative blood transfusion is common in patients undergoing cytoreductive surgery. In this study, EBL and preoperative hemoglobin levels were significantly associated with transfusion receipt. Clinicians should optimize hemoglobin levels and intraoperative blood conservation strategies to reduce the need for transfusion. The results also highlight the importance of considering racial and ethnic differences when developing strategies to reduce transfusion risk.

The clinical effectiveness and safety of Zone III REBOA for resection of sacropelvic tumors in patients older than 70 years.

BACKGROUND: REBOA is a method used to manage bleeding during surgery involving sacropelvic tumors. Nevertheless, studies on the use of REBOA among elderly people are lacking. The aim of this research was to investigate the efficacy and safety of Zone III REBOA in patients aged more than 70 years. METHODS: A comparative study was conducted using case-control methods. A group of patients, referred to as Group A, who were younger than 70 years was identified and paired with a comparable group of patients, known as Group B, who were older than 70 years. Continuous monitoring of physiological parameters was conducted, and blood samples were collected at consistent intervals. RESULTS: Totally, 188 participants were enrolled and received REBOA. Among the 188 patients, seventeen were aged more than 70 years. By implementing REBOA, the average amount of blood loss was only 1427 ml. Experiments were also conducted to compare Group A and Group B. No notable differences were observed in terms of demographic variables, systolic blood pressure (SBP), arterial pH, lactate levels, blood creatinine levels, potassium levels, or calcium levels at baseline. Additionally, after the deflation of the REBOA, laboratory test results, which included arterial pH, lactate, potassium concentration, calcium concentration, and blood creatinine concentration, were not significantly different (P > 0.05). CONCLUSION: This study indicated that in selected patients aged more than 70 years can achieve satisfactory hemodynamic and metabolic stability with Zone III REBOA. LEVEL OF EVIDENCE: Therapeutic study, Level III.

Endoscopic management of intraprocedural bleeding during endoscopic interventions.

Endoscopic resection techniques have evolved over time, allowing effective and safe resection of the majority of pre-malignant and early cancerous lesions in the gastrointestinal tract. Bleeding is one of the most commonly encountered complications during endoscopic resection, which can interfere with the procedure and result in serious adverse events. Intraprocedural bleeding is relatively common during endoscopic resection and, in most cases, is a mild and self-limiting event. However, it can interfere with the completion of the resection and may result in negative patient-related outcomes in severe cases, including the need for hospitalization and blood transfusion as well as the requirement for radiological or surgical interventions. Appropriate management of intraprocedural bleeding can improve the safety and efficacy of endoscopic resection, and it can be readily achieved with the use of several endoscopic hemostatic tools. In this review, we discuss the recent advances in the approach to intraprocedural bleeding complicating endoscopic resection, with a focus on the various endoscopic hemostatic tools available to manage such events safely and effectively.

A review of vaginal hysterectomies in the gynaecology department of a tertiary care hospital.

This retrospective cohort study analysed the trends and complications of vaginal hysterectomy conducted at Services Hospital, Lahore, from January 1, 2015 to December 31, 2020. Demographics, indications, surgery duration, complications (haemorrhage, urological or rectal problems, infection), and hospital stay were recorded. Out of 819 hysterectomies performed for benign gynaecological conditions, 112 (13.68%) were vaginal hysterectomies. Non-descent vaginal hysterectomy (NDVH) accounted for 33(29.46%) and uterine prolapse for 79(70.53%) of the cases. Mean age was 52.35±8.74 years, parity was 5.01±1.32, intraoperative haemorrhage was 796.87±450.1 ml, surgery duration was 48.61±12.28 minutes, and hospital stay was 2.58±0.41 days. Complications occurred in 19(16.97%) of the cases, while 93(83.03%) cases had no complications. Outcomes were comparable between NDVH and vaginal hysterectomy for prolapse (p=0.552). This indicates that vaginal hysterectomy is a safe procedure with minimal complications and quick recovery for uterine prolapse and non-descent uterus. However, a declining trend was observed over the study period.

The effect of preoperative use of anticoagulants on the hemostatic effect of intravenous application of tranexamic acid in PLIF: a case control study.

Intravenous application of tranexamic acid (TXA) in posterior lumbar interbody fusion (PLIF) can effectively reduce blood loss without affecting coagulation function. However, it has not been reported whether preoperative use of anticoagulants may affect the efficacy of TXA in PLIF. The purpose of this study is to observe the effect of preoperative use of anticoagulants on coagulation indicators and blood loss after PLIF receiving intravenous unit dose TXA. A retrospective analysis was conducted on data from 53 patients with PLIF between 2020.11 and 2022.9, who received intravenous application of a unit dose of TXA (1 g/100 mL) 15 min before the skin incision after general anesthesia. Those who used anticoagulants within one week before surgery were recorded as the observation group, while those who did not use anticoagulants were recorded as the control group. The main observation indicators include surgical time, intraoperative blood loss, postoperative drainage volume, blood transfusion, and red blood cell (RBC), hemoglobin (HB), and hematocrit (HCT) measured on the 1st, 4th, 7th, and last-test postoperative days. Secondary observation indicators included postoperative incision healing, deep vein thrombosis of lower limbs, postoperative hospital stay, and activated partial thrombin time (APTT), prothrombin time (PT), thrombin time (TT), fibrinogen (FIB), and platelets (PLT) on the 1st and 4th days after surgery. The operation was successfully completed in both groups, the incision healed well after operation, and no lower limb deep vein thrombosis occurred. There was no significant difference in surgical time, intraoperative blood loss, postoperative drainage volume, and blood transfusion between the two groups (p > 0.05). There was no significant difference in the RBC, HB, and HCT measured on the 1st, 4th, 7th, and last-test postoperative days between the two groups (p > 0.05). There was no statistically significant difference in APTT, PT, TT, FIB and PLT between the two groups on the 1st and 4th postoperative days (p > 0.05). There was no significant difference in postoperative hospital stay between the two groups (p > 0.05). The use of anticoagulants within one week before surgery does not affect the hemostatic effect of intravenous unit dose TXA in PLIF.

The safety and short-term effect of mixed approach in laparoscopic right hemicolectomy for right colon cancer compared with middle approach: a retrospective study.

PURPOSE: To investigate whether the mixed approach is a safe and advantageous way to operate laparoscopic right hemicolectomy. METHODS: A retrospective study was performed on 316 patients who underwent laparoscopic right hemicolectomy in our center. They were assigned to the middle approach group (n = 158) and the mixed approach group (n = 158) according to the surgical approaches. The baseline data like gender、age and body mass index as well as the intraoperative and postoperative conditions including operation time, blood loss, postoperative hospital stay and complications were analyzed. RESULTS: There were no significant differences in age, sex, BMI, ASA grade and tumor characteristics between the two groups. Compared with the middle approach group, the mixed approach group was significantly lower in terms of operation time (217.61 min vs 154.31 min, p < 0.001), intraoperative blood loss (73.8 ml vs 37.97 ml, p < 0.001) and postoperative drainage volume. There was no significant difference in the postoperative complications like postoperative anastomotic leakage, postoperative infection and postoperative intestinal obstruction. CONCLUSIONS: Compared with the middle approach, the mixed approach is a safe and advantageous way that can significantly shorten the operation time, reduce intraoperative bleeding and postoperative drainage volume, and does not prolong the length of hospital stay or increase the morbidity postoperative complications.

[Evaluation of factors associated with major hemorrhage in patients undergoing primary total hip arthroplasty]. / Evaluación de factores asociados a hemorragia mayor en pacientes sometidos a artroplastía total de cadera primaria.

INTRODUCTION: the use of blood transfusions leads to increased hospital costs and an increased risk of medical complications and death. Therefore, it is necessary to study the incidence of major bleeding events and the factors associated with these outcomes in patients undergoing primary total hip arthroplasty (THA). MATERIAL AND METHODS: observational, longitudinal and prospective study, carried out at the High Specialty Medical Unit of Traumatology and Orthopedics of Lomas Verdes of the Mexican Institute of Social Security, in the Joint Replacement Service, in the period from March 1, 2020 to July 1, 2020. RESULTS: the incidence of major bleeding in patients undergoing primary THA was 84.8%, when considering two criteria: a decrease in hemoglobin 2 g/dl and the need for transfusion 2 units of red blood cells. This figure increased to 87.1% when also including trans-surgical bleeding at its 75th percentile, equivalent to 500 ml. Transfusion of at least one unit of red blood cells during surgery was performed in 68% of patients. Trans-surgical bleeding reached a maximum of 1,900 ml, with a 75th percentile of 500 ml. Unlike other studies, in our institution, female gender did not prove to be a significant risk factor for major bleeding. CONCLUSION: it is advisable to analyze the procedures and particularities of THA surgery that may be associated with a lower risk of bleeding in older patients.

INTRODUCCIÓN: el uso de transfusiones sanguíneas conlleva aumentos en los costos hospitalarios y un mayor riesgo de complicaciones médicas y fallecimientos; por lo que es necesario el estudio de la incidencia de eventos de hemorragia mayor y de los factores que se asocien a estos desenlaces en los pacientes que se someten a una artroplastía total de cadera (ATC) primaria. MATERIAL Y MÉTODOS: estudio observacional, longitudinal y prospectivo, llevado a cabo en la Unidad Médica de Alta Especialidad de Traumatología y Ortopedia de Lomas Verdes del Instituto Mexicano del Seguro Social, en el Servicio de Reemplazo Articular, en el período comprendido entre el 01 Marzo 2020 al 01 Julio 2020. RESULTADOS: la incidencia de hemorragia mayor en pacientes sometidos a ATC primaria fue de 84.8%, al considerarse dos criterios: una disminución de hemoglobina 2 g/dl y la necesidad de transfusión 2 unidades de glóbulos rojos. Esta cifra aumentó a 87.1% al incluir también el sangrado transquirúrgico en su percentil 75, equivalente a 500 ml. La transfusión de al menos una unidad de glóbulos rojos durante la cirugía se realizó en 68% de los pacientes. El sangrado transquirúrgico alcanzó un máximo de 1,900 ml, con un percentil 75 de 500 ml. A diferencia de otros estudios, en nuestra institución, el género femenino no demostró ser un factor de riesgo significativo para la hemorragia mayor. CONCLUSIÓN: es aconsejable analizar los procedimientos y las particularidades de la cirugía de ATC que puedan estar asociados con un menor riesgo de hemorragia en los pacientes mayores.

The effect of enhanced recovery after lung cancer surgery combined with fine surgical nursing on rehabilitation.

Objectives: To analyse the enhanced recovery after surgery approach combined with fine surgical nursing on recovery time, pain, sleep quality and satisfaction with care after lung cancer surgery. METHODS: The cross-sectional study was conducted at the Nanjing Chest Hospital, China, from October 2019 to March 2022, and comprised non-small cell lung cancer patients undergoing single-port video-assisted thoracoscopic surgery. Patients receiving fine surgical nursing in addition to conventional enhanced recovery after surgery formed the intervention group A, while those receiving the conventional enhanced recovery after surgery care alone formed control group B. Intraoperative blood loss, operative time, extubation time and length of stay values were noted for both the groups using standard scales. Nursing satisfaction and the incidence of adverse reactions in the two groups were also noted. Data was analysed using SPSS 23. RESULTS: Of the 99 patients, 46(46.5%) were in group A; 23(50%) males and 23(50%) females with mean age 70.3±4.8 years and mean body mass index 26.76±2.55kg/m2. There were 53(53.5%) patients in group B: 16(30.2%) males and 37(69.8%) females with mean age 69.9±4.4 years and mean body mass index 25.93±2.40kg/m2 (p>0.05). Intraoperative blood loss, operative time, postoperative extubation time and length of stay in group A were lower than those in group B (p<0.05). Pain and sleep quality values in group A were lower, while health status value was higher than group B (p<0.05). Group A had significantly higher nursing satisfaction compared to group B (p<0.05). Conclusion: The use of enhanced recovery after surgery combined with fine surgical nursing in patients with nonsmall cell lung cancer after video-assisted thoracoscopic surgery promoted postoperative recovery.

The impact of low pressure pneumoperitoneum in robotic assisted radical prostatectomy II: a prospective, randomized, double blinded trial.

OBJECTIVE: To analyze postoperative ileus rates and postoperative complications between the different pneumoperitoneum settings. The secondary objective was to evaluate narcotic use and intraoperative blood loss between the different pneumoperitoneum settings. METHODS: A prospective, randomized, double blinded study was conducted at pneumoperitoneum pressures of either 12 mmHg or 15 mmHg for patients undergoing robotic assisted radical prostatectomy with bilateral pelvic lymph node dissection by a single high volume surgeon. RESULTS: The risk of ileus in the 12 mmHg group was 1.9% (2/105) compared to 3.2% (3/93) in the 15 mmHg group (OR 0.58, 95%CI 0.1-3.6). There was no difference in the risk of any complication with a complication rate of 4.8% (5/105) in the 12 mmHg arm compared to 4.3% (4/93) in the 15 mmHg arm (OR 1.1, 95% CI 0.3 - 4.3). CONCLUSION: Pneumoperitoneum pressure setting of 12 mmHg has no significant difference to 15 mmHg in the rate of postoperative complications, narcotic use, and intraoperative bleeding. Additional research is warranted to understand the optimal.

Direct Anterior Approach Total Hip Arthroplasty for Femoral Neck Fractures in the Lateral Position.

Objective: To compare the clinical efficacy of artificial total hip arthroplasty(THA) for femoral neck fracture between direct anterior approach(DAA) in lateral position and posterior lateral approach(PLA). Methods: Comparison of 200 cases of patients who underwent THA collected between September 2019 and August 2021 was done. Incision length, intraoperative bleeding, operative time, difference in postoperative haemoglobin from preoperative levels, length of hospital stay, postoperative time to get off the floor, visual analogue score (VAS) for pain, preoperative and postoperative Harris scores for the hip, and measurements of the acetabular abduction angle and anterior acetabular tilt angle at 6 months postoperatively were collected, and all the cases were followed up for at least 2 years. Results: Compared with the PLA group, the DAA group had a shorter incision length, less intraoperative blood loss, less postoperative haemoglobin reduction compared with the preoperative period, a shorter hospital stay and an earlier first time to get off the floor after surgery, however, the comparison of operative times was not statistically significant; Patients in the DAA group had a lower VAS in the early postoperative period compared to PLA; Patients in the DAA group had higher hip Harris scores at 6 weeks and 6 months postoperatively; There was no significant difference in acetabular abduction angle and acetabular anterior tilt angle between the two groups at 6 months postoperatively. Conclusion: Compared to PLA, DAA in THA is minimally invasive, has less pain, less bleeding, earlier time out of bed, shorter hospital stay, better early hip function, faster rehabilitation, and better joint stability.

Robot-assisted versus traditional surgery in the treatment of intertrochanteric fractures: a meta-analysis.

Intramedullary nail fixation of intertrochanteric fractures assisted by orthopedic surgical robot navigation is a new surgical method, but there are few studies comparing its efficacy with traditional intramedullary nail fixation. We aimed to assess whether robot-assisted internal fixation confers certain surgical advantages through a literature review. PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI) and Wan fang Data Knowledge service Platform were searched to collect randomized and non-randomized studies on patients with calcaneal fractures. Five studies were identified to compare the clinical indexes. For the clinical indexes, the technology of robot-assisted is generally feasible, in time to operation, intraoperative fluoroscopy times, blood loss, pine insertion, tip apex distance (TAD), and Harris score (P < 0.05). However, on the complication and excellent and good rate after operation did not show good efficacy compared with the traditional group (P > 0.05). Based on the current evidence, For the short-term clinical index, the advantages of robot-assisted are clear. The long-term clinical effects of the two methods are also good, but the robot-assisted shows better. However, the quality of some studies is low, and more high-quality randomized controlled trials (RCTs) are needed for further verification.

The use of indocyanine green for lateral lymph node dissection in rectal cancer-preliminary data from an emerging procedure: a systematic review of the literature.

INTRODUCTION: Lateral lymph node dissection (LLND) for rectal cancer is still not a widely established technique owing to the existing controversy between Eastern and Western countries and the lack of well-designed studies. The risk of complications and the paucity of long-term oncological results are significant drawbacks for further applying this technique. The use of indocyanine green (ICG) near-infrared (NIR) fluorescence for LLND appears as a promising technique for enhancing postoperative and oncological outcomes. This review aims to evaluate the emerging role of ICG during LLND and present the benefits of its application. MATERIALS AND METHODS: Systematic electronic research was conducted in PubMed and Google Scholar using a combination of medical subject headings (MeSH). Studies presenting the use of ICG during LLND, especially in terms of harvested lymph nodes, were included and reviewed. Studies comparing LLND with ICG (LLND + ICG) or without ICG (LLND-alone) were further analyzed for the number of lymph nodes and postoperative outcomes. RESULTS: In total, 13 studies were found eligible and analyzed for different parameters. LLND + ICG is associated with significantly increased number of harvested lateral lymph nodes (p < 0.05), minor blood loss, decreased operative time, and probably decreased urinary retention postoperatively compared with LLND-alone. CONCLUSIONS: The use of ICG fluorescence during LLND is a safe and feasible technique for balancing postoperative outcomes and the number of harvested lymph nodes. Well-designed studies with long-term results are required to elucidate the oncological benefits and establish this promising technique.
