Laparoscopic Versus Open Pancreatoduodenectomy for Periampullary Tumors: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Laparoscopic pancreatoduodenectomy (LPD) has emerged as an alternative to open technique in treating periampullary tumors. However, the safety and efficacy of LPD compared to open pancreatoduodenectomy (OPD) remain unclear. Thus, we conducted an updated meta-analysis to evaluate the efficacy and safety of LPD versus OPD in patients with periampullary tumors, with a particular focus on the pancreatic ductal adenocarcinoma patient subgroup. According to PRISMA guidelines, we searched PubMed, Embase, and Cochrane Library in December 2023 for randomized controlled trials (RCTs) that directly compare LPD versus OPD in patients with periampullary tumors. Endpoints and sensitive analysis were conducted for short-term endpoints. All statistical analysis was performed using R software version 4.3.1 with a random-effects model. Five RCTs yielding 1018 patients with periampullary tumors were included, of whom 511 (50.2%) were randomized to the LPD group. Total follow-up time was 90days. LPD was associated with a longer operation time (MD 66.75; 95% CI 26.59 to 106.92; p = 0.001; I2 = 87%; Fig.1A), lower intraoperative blood loss (MD - 124.05; 95% CI - 178.56 to - 69.53; p < 0.001; I2 = 86%; Fig.1B), and shorter length of stay (MD - 1.37; 95% IC - 2.31 to - 0.43; p = 0.004; I2 = 14%; Fig.1C) as compared with OPD. In terms of 90-day mortality rates and number of lymph nodes yield, no significant differences were found between both groups. Our meta-analysis of RCTs suggests that LPD is an effective and safe alternative for patients with periampullary tumors, with lower intraoperative blood loss and shorter length of stay.

Innovations in the management of epistaxis secondary to hereditary hemorrhagic telangiectasia: our evolution to injection sclerotherapy as the treatment of choice.

We compared the efficacy of intralesional sclerotherapy using 3% sodium tetradecyl sulfate with non-sclerotherapy-based treatments for Hereditary Hemorrhagic Telangiectasia-associated epistaxis management. This is a retrospective study of patients who underwent surgical intervention for HHT-associated epistaxis management from 01/2010-02/2024. Patients undergoing sclerotherapy with intralesional 3% sodium tetradecyl sulfate were included in the sclerotherapy group and others undergoing conventional non-sclerotherapy-based procedures in the non-sclerotherapy group. Outcomes like breakthrough epistaxis, emergency visits, intra-op blood loss, blood transfusions, and procedure complications in the 3-month perioperative period were compared. Twenty-three patients who underwent 74 intranasal procedures were identified. In the sclerotherapy group, 17 patients underwent 47 procedures. In the non-sclerotherapy group, 10 patients underwent 27 procedures. Till the 3rd post-treatment month, fewer breakthrough epistaxis episodes were observed after sclerotherapy procedures (13/47) vs. non-sclerotherapy procedures (14/27); (p = 0.037). Intraoperative blood loss was significantly lower during sclerotherapy (median: 10 ml) vs. non-sclerotherapy procedures (median: 50 ml); p < 0.001. The time interval between successive procedures was not significantly different in the sclerotherapy (median 6.5 months) vs. the non-sclerotherapy group (median 3.5 months); p = 0.13. Nasal crusting was the most common complication in the sclerotherapy group (36.9%). Two patients in each group had new onset septal perforation, none of the patients had vision loss or cerebrovascular accident. One emergency department visit was reported in the sclerotherapy group vs. 7 (in 3 patients) in the non-sclerotherapy group. Compared to non-sclerotherapy treatments, intralesional sclerotherapy for epistaxis in HHT is more effective in decreasing breakthrough epistaxis, and has lower intraoperative blood loss.

Comparison of Da Vinci Robotic-assisted With Open Kasai Portoenterostomy for Biliary Atresia

BackgroundRobotic-assisted Kasai portoenterostomy (RAKPE) has been used to treat biliary atresia (BA). This study aimed to compare the efficacy of RAKPE and open Kasai portoenterostomy (OKPE) for BA. MethodsThirty-one children with type III BA who underwent surgical treatment in two centers from January 2022 to December 2023 were retrospectively collected. According to the operative techniques, the participants were divided into the RAKPE group (13 cases) and the OKPE group (18 cases). The operative time, jaundice clearance (JC) rate, and incidence of cholangitis were analyzed. ResultsThe operative time in the RAKPE group (204.3 ± 19.9 min) was significantly longer than that in the OKPE group (186.2 ± 22.2 min), P < 0.05. However, the blood loss (8.1 ± 2.5 ml) in the RAKPE group was significantly decreased compared with the OKPE group (13.6 ± 4.8 ml), and 15.4% patient need blood transfusion in RAKEP group was litter than that 55.6% in the OKPE group, P < 0.05. The time to oral feeding (2.8 ± 0.4 days vs. 4.3 ± 0.7 days) and the time to pass ICG-positive stools (3.6 ± 0.6 days vs. 4.7 ± 0.9 days) in the RAKPE group were significantly shorter than those in the OKPE group, P < 0.05. No significant differences were observed in the bile excretion rate, hospital stay time, and JC rate. The incidence of cholangitis in the RAKPE group was significantly lower than that in the OKPE group during short follow-up. ConclusionRAKPE may be associated with lower intraoperative blood loss, decrease need for postoperative transfusions and decreased rate of postoperative cholangitis compared to OKPE.

Comparison of thyroid surgery techniques: a retrospective cohort study and meta-analysis of traditional electric knife vs. straight bipolar electrocoagulation forceps.

In recent years, advancements in surgical techniques for thyroidectomy have led to varying outcomes and efficiencies. Understanding these differences is crucial to optimize patient care and surgical success. This study compared intra- and postoperative parameters of thyroid surgery for thyroidectomy or thyroid cancer. One approach involved the traditional electric knife, employing traditional clamp-ligation skills and an electric knife. The other approach utilized straight bipolar electrocoagulation forceps for micro-hemostasis and micro-cutting. Data were analyzed retrospectively for 228 patients who underwent thyroidectomy at the Third Affiliated Hospital of Kunming Medical University from January 2014 to November 2018. Surgery was performed either as traditional open surgery (n=150) or as a meticulous anatomical procedure involving bipolar electrocoagulation (n=78). In addition, data from published studies comparing the two surgical procedures were meta-analyzed. The bipolar electrocoagulation procedure was associated with significantly shorter total operation time, lower intraoperative blood loss and lower rate of hypocalcemia. The two procedures were associated with similar rates of hoarseness. Meta-analysis of eight studies involving 2,080 patients showed that bipolar electrocoagulation was associated with significantly shorter total operation time than the traditional approach (mean difference =-21.29 min, 95% CI: -26.32 to -16.27) and with less intraoperative bleeding (mean difference =-12.87 min, 95% CI: -23.81 to -1.93). Straight bipolar electrocoagulation forceps can be used to perform fine dissection during thyroid surgery. Performing "micro-hemostasis" and "micro-cutting" manipulations with these straight bipolar forceps can smoothly dissect nerves and parathyroid glands and may reduce intraoperative bleeding, operation time and rates of postoperative complications, might accelerate recovery after surgery.

Exploring the clinical value of direct anterior approach THA for short-term hip function improvement: A single-center retrospective analysis of short-term outcomes.

To investigate the outcomes of the direct anterior approach (DAA) in total hip arthroplasty (THA) and its impact on improving hip joint function. This retrospective analysis included 94 patients who underwent THA between December 2017 and December 2020 at Dongguan Hospital, Guangzhou University of Chinese Medicine. The study group comprised 50 patients who received the DAA, while the control group comprised 44 patients who received the postero-lateral approach (PA). The follow-up period was 12 months. A comparison was made between the 2 groups based on perioperative indicators (operation time, intraoperative blood loss, hospitalization time, bed rest time, incision length, pain score), duration of walker use, incidence of postoperative complications, hip joint function (Harris score), quality of life (SF-36), and activities of daily living (ADL). The treatment effectiveness rate was higher in the study group (P < .05). The study group had a longer operation time, lower intraoperative blood loss, shorter hospitalization and bed rest time, smaller incision length, and lower visual analog scale (VAS) score after treatment, with statistically significant differences (P < .05). The study group also had a shorter duration of walker use after surgery (P < .05). The Harris score after treatment was higher in the study group compared to the control group (P < .05). Additionally, the study group had higher SF-36 scores and ADL scores after treatment (P < .05). There was no significant difference in the incidence of postoperative complications between the 2 groups (P > .05). The DAA in THA resulted in reduced pain and intraoperative blood loss, contributing to the promotion of postoperative recovery in patients with good short-term outcomes. This procedure warrants further promotion.

Laparoscopic versus open pancreatoduodenectomy for periampullary tumors: An updated systematic review and meta-analysis.

e16362 Background: Laparoscopic pancreatoduodenectomy (LPD) has emerged as an alternative to open technique in treating periampullary tumors, particularly pancreatic ductal adenocarcinoma (PDAC). However, the evidence regarding safety and efficacy of LPD compared to open pancreatoduodenectomy (OPD) remains unclear. Methods: According to PRISMA guidelines, we searched PubMed, Embase, and Cochrane Library in December 2023 for randomized controlled trials (RCTs) that directly compare LPD versus OPD in patients with periampullary tumors. Outcomes were stratified as intraoperative outcomes, postoperative complications, in-hospital and short-term, and prespecified subanalysis was performed in patients with PDAC. All statistical analysis was performed using R software version 4.3.1 with a random-effects model. Results: Five RCTs yielding 1,018 patients with periampullary tumors were included, of whom 511 (50.2%) were randomized to LPD group. The total follow-up time was 90 days. LPD was associated with a longer operation time (MD 66.75; 95% CI 26.59 to 106.92; p = 0.001; I2= 87%; Figure 1A), lower intraoperative blood loss (MD -124.05; 95% CI -178.56 to -69.53; p &lt; 0.001; I2= 86%; Figure 1B), and shorter length of stay (MD -1.37; 95% IC -2.31 to -0.43; p = 0.004; I2= 14%; Figure 1C) as compared to OPD. In terms of 90-day mortality rates and number of lymph nodes yield, no significant differences were found between both groups. Subgroup analysis for PDAC consistently aligned with the overall results and provided relatively lower heterogeneity compared to the primary analysis. Conclusions: Our meta-analysis of RCTs suggests that LPD is an effective and safe alternative for patients with periampullary tumors, with lower intraoperative blood loss and shorter length of stay.

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 ≥6cm, 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.

Laparoscopic Versus Open Gastrectomy for Advanced Gastric Cancer: A Meta-Analysis of Randomized Controlled Trials.

Laparoscopy-assisted gastrectomy (LAG) is a well-established surgical technique in treating patients with early gastric cancer. However, the efficacy and safety of LAG versus open gastrectomy (OG) in patients with advanced gastric cancer (AGC) remains unclear. We systematically searched PubMed, Embase, and Cochrane Library in June 2023 for RCTs comparing LAG versus OG in patients with AGC. We pooled risk ratios (RR) and mean differences (MD) with 95% confidence intervals (CI) for binary and continuous endpoints, respectively. We performed all statistical analyses using R software version 4.3.1 and a random-effects model. Nine RCTs comprising 3827 patients were included. There were no differences in terms of intraoperative complications (RR 1.14; 95% CI 0.72 to 1.82), number of retrieved lymph nodes (MD -0.54lymph nodes; 95% CI -1.18 to 0.09), or mortality (RR 0.91; 95% CI 0.30 to 2.83). LAG was associated with a longer operative time (MD 49.28minutes; 95% CI 30.88 to 67.69), lower intraoperative blood loss (MD -51.24milliliters; 95% CI -81.41 to -21.06), shorter length of stay (MD -0.83days; 95% CI -1.60 to -0.06), and higher incidence of pancreatic fistula (RR 2.44; 95% CI 1.08 to 5.50). Postoperatively, LAG was also superior to OG in reducing bleeding rates (RR 0.44; 95% CI 0.22 to 0.86) and time to first flatus (MD -0.27days; 95% CI -0.47 to -0.07), with comparable results in anastomotic leakage, wound healing issues, major complications, time to ambulation, or time to first liquid intake. In the long-term analyses at 3 and 5years, there were no significant differences between LAG and OG in terms of overall survival (RR 0.99; 95% CI 0.96 to 1.03) or relapse-free survival (RR 0.99; 95% CI 0.94 to 1.04). This meta-analysis of RCTs suggests that LAG may be an effective and safe alternative to OG for treating AGC; albeit, it may be associated with an increased risk for pancreatic fistula.

No Difference in Clinical and Hospital Quality Outcomes in Treatment of Reverse Obliquity Intertrochanteric Hip Fractures (AO/OTA 31.A3) Based on Cephalomedullary Nail Length

IntroductionThe purpose of this study was to evaluate outcomes following reverse obliquity (RO) intertrochanteric hip fractures based on the use of short cephalomedullary nails (CMNs) compared to long CMNs for fixation. MethodsAn IRB-approved prospectively collected hip fracture registry at an urban academic medical center was queried for all AO/OTA 31A3.1-3 reverse obliquity intertrochanteric (RO) fractures. One hundred and seventy patients with age > 55 years old and minimum 6-month follow-up were identified for analysis. Data was collected for patient demographics, injury details, intraoperative radiographic parameters, perioperative physiologic parameters, hospital quality measures, and outcomes including radiographic time to healing, need for reoperation, nonunion, and mortality. Comparative analyses were conducted between cohorts. Additional multivariable binary logistic and linear regression analyses were performed to evaluate for factors independently associated with short and long nail usage. ResultsThe mean age of the entire cohort was 80.91±10.09 years: 103 patients had a long CMN implanted, and 67 patients had a short CMN implanted. There were no demographic differences or differences in radiographic time to healing, rates of mortality, readmission, nonunion, and need for reoperation. Univariable analysis revealed that short CMN had lower intraoperative blood loss (111.19±83.97mL vs 176.72±161.45mL, p=0.002), decreased need for transfusion (37% vs. 55%, p=0.022), and shorter procedures (118.67±57.87min vs. 148.95±77.83min, p=0.002. Multivariable analysis revealed that short nail usage was associated with decreased intraoperative blood loss, decreased need for transfusion, and shorter operative times. ConclusionNail length does not affect healing or hospital quality outcomes in the treatment of RO hip fractures. The use of short CMNs for these fractures did correlate with lower intraoperative blood loss, operative time, and need for blood transfusion, with non-inferior outcomes and similar hospital quality measures when compared to long CMNs.

Management of recurrent lumbar disc herniation: a comparative analysis of posterior lumbar interbody fusion and repeat discectomy

Background: For recurrent lumbar disc herniation, many experts suggest a repeat discectomy without stabilization due to its minimal tissue manipulation, lower blood loss, shorter hospital stay, and lower cost, recent research on the role of instability in disc herniation has made fusion techniques popular among spinal surgeons. The authors compare the postoperative outcomes of posterior lumbar interbody fusion (PLIF) and repeat discectomy for same-level recurrent disc herniation. Methods: The patients included had previously undergone discectomy and presented with a same-level recurrent lumbar disc herniation. The patients were placed into two groups: 1) discectomy only, 2) PLIF based on the absence or presence of segmental instability. Preoperative and postoperative Oswestry disability index scores, duration of surgery, blood loss, duration of hospitalization, and complications were analyzed. Results: The repeat discectomy and fusion groups had 40 and 34 patients, respectively. The patients were followed up for 2.68 (1–4) years. There was no difference in the duration of hospitalization (3.73 vs. 3.29 days P=0.581) and operative time (101.25 vs. 108.82 mins, P=0.48). Repeat discectomy had lower intraoperative blood loss, 88.75 ml (50–150) versus 111.47 ml (30–250) in PLIF (P=0.289). PLIF had better ODI pain score 4.21 (0–10) versus 9.27 (0–20) (P-value of 0.018). Recurrence was 22.5% in repeat discectomy versus 0 in PLIF. Conclusion: PLIF and repeat discectomy for recurrent lumbar disc herniation have comparable intraoperative blood loss, duration of surgery, and hospital stay. PLIF is associated with lower durotomy rates and better long-term pain control than discectomy. This is due to recurrence and progression of degenerative process in discectomy patients, which are eliminated and slowed, respectively, by PLIF.

Prospective assessment of adenocarcinoma of esophagogastric junction (AEG) following radical resection: Real-world insights from the CLAEG study.

TPS415 Background: The CLAEG study (ChiCTR1900026131) is a prospective, real-world data evaluation of the clinical outcomes of patients with AEG following radical resection to investigate lymph node (LN) metastasis patterns and refine treatment strategies. Methods: Data from 44 hospitals in China were collected using a designed CRF, comprising baseline, surgical details, pathology results and recovery progress from January 1,2020. Data cut-off was August 31, 2023. The study is ongoing. Results: A total of 1322 patients were enrolled, and only 946 patients with complete data were included in the analysis. The median age was 65 years (range, 24-90). Among them, 28 patients were classified as Siewert type I, 601 as type II, and 317 as type III. Laparoscopic surgery was performed in 845 patients, while 101 underwent open surgery, with no significant difference in postoperative complication rate between them. However, the laparoscopic group demonstrated superior favorable outcomes in terms of postoperative recovery times, with shorter postoperative exhaust time (3.0 days vs 3.6 days, p&lt;0.001), feeding time (5.0 days vs 5.8 days, p=0.013), discharge time (11.6 days vs 14.6 days, p=0.002), as well as lower intraoperative blood loss (103.9 ml vs 163.4 ml, p=0.001). Among the patients, 891 underwent transhiatal approach, while 55 underwent thoracoabdominal approach, and no significant differences in postoperative complication rates, intraoperative blood loss and hospital stay were observed between these approaches. However, the transhiatal approach was associated with a shorter operative time (244.2 min vs 309.3 min, p&lt;0.001). LN dissection was performed in all patients within the abdominal region, with additional mediastinal LN dissection in 293 patients. The LN metastasis rates were 7.04%, 0% and 5.71% for No. 110, 111 and 112, respectively. Within the abdominal LNs, category-1 nodes included No. 1, 2, 3, 4, 5, 7, 8a, 9, 11, 19, while category-2 included No. 6, 12a, 20. Total gastrectomy was performed in 657 patients, while proximal gastrectomy was performed in 289 patients, and there were no significant differences in the rates of postoperative complications, postoperative recovery times and hospital stay between them. However, total gastrectomy took less operation time (243.7 min vs 258.0 min, p=0.019), and more LNs (36.6 vs 23.3, p&lt;0.001) were detected in abdomen. Conclusion: The CLAEG study confirms the safety and feasibility of laparoscopy in AEG surgery, although its long-term oncology effectiveness requires further investigation. Transhiatal surgery is advantageous due to its shorter operation time. Both proximal and total gastrectomy can be considered as viable surgical options. AEG patients have a higher rate of abdominal LN metastasis but a lower rate of mediastinal node involvement, emphasizing the importance of precise abdominal LN retrieval.

Comparison of Posterior Approach and Combined Anterior-Posterior Approach in the Treatment of Ankylosing Spondylitis Combined With Cervical Spine Fracture: A Systematic Review and Meta-Analysis.

Systematic review. To compare the efficacy of the posterior approach and combined anterior-posterior approach in the treatment of ankylosing spondylitis (AS) with cervical spine fracture by meta-analysis. The databases PubMed, Web of Science, Embase, and Cochrane Library were searched for studies on the comparison of the posterior approach group and the combined anterior-posterior approach group in the treatment of ankylosing spondylitis combined with cervical spine fracture from database establishment to August 2023. The procedure time, intraoperative blood loss, the rates of neurological improvement, mean change in the postoperative neurological function, complication rates, rates of revised surgery, and mortality were extracted. Meta-analysis was performed using RevMan 5.4 software provided by Cochrane Library. A total of 11 retrospective cohort studies with a total of 215 patients were included in this study. The posterior approach group had lower intraoperative blood loss than the combined anterior-posterior approach group [Mean difference (MD) = -146.05, 95%CI(-187.40,-104.69), P < .00001]; the operation time was significantly less in the posterior approach group than in the combined anterior-posterior approach group [MD = -95.34, 95%CI(-113.13,-77.55), P < .00001]. There were no statistically significant differences in the neurological improvement rates, mean changes in postoperative neurological function, complication rates, modified surgery rates, and mortality rates. Both the posterior approach and combined anterior and posterior approach can achieve good results. Clinicians should develop an individualized approach based on the patient's fracture type, degree of spinal cord injury, fracture stability, fracture dislocation, general condition, and underlying disease.

Comparison of outcomes of laparotomic and minimally invasive radical hysterectomy in women with early-stage cervical cancer.

This study compared the outcomes of laparotomic radical hysterectomy (LRH) and minimally invasive radical hysterectomy (MISRH) in patients with early-stage cervical cancer. The clinical data of patients with early-stage cervical cancer who underwent LRH or MISRH (laparoscopic/robotic) at Chang Gung Memorial Hospital, Linkou Branch, from 2002 to 2017 were retrospectively reviewed. The surgical safety (operation time, blood loss, blood transfusion rate, length of postoperative stay, and perioperative complications), overall survival (OS), disease-free survival (DFS), and recurrence pattern were analyzed. Propensity score matching (PSM) at a 3:1 ratio was performed to balance prognostic variables. Of the 760 patients (entire cohort), 614 underwent LRH and 146 underwent MISRH. After PSM, 394 and 140 patients were included in the LRH and MISRH groups, respectively. The 5-year OS rate was significantly lower in the MISRH group than in the LRH group (85.6% vs. 93.2%, p=0.043), and the 5-year DFS rate (p=0.21) did not differ significantly. After PSM, the 5-year OS rates did not differ significantly between the MISRH and LRH groups (87.1% vs. 92.1%, p=0.393). The MISRH group had a significantly shorter operation time (p<0.001), lower intraoperative blood loss (p<0.001), lower blood transfusion rate (p<0.001), and shorter postoperative stay (p<0.001) but a significantly higher rate of intraoperative bladder injury (p<0.001) than the LRH group. After PSM, MISRH is associated with nonsignificantly lower OS but a significantly higher risk of intraoperative urological complications than LRH.

Comparison of the therapeutic efficacy of hip arthroplasty and proximal femoral nail antirotation internal fixation for unstable intertrochanteric femur fractures.

To compare the therapeutic efficacy of total hip arthroplasty (THA) versus proximal femoral nail antirotation (PFNA) internal fixation for treating unstable intertrochanteric femur fractures (UIFF). In this retrospective study, the clinical data of 86 patients with intertrochanteric femur fractures (IFF) treated in Hangzhou Fuyang Hospital of Orthopedics of Traditional Chinese Medicine from January 2022 to December 2023 were collected and analyzed. Patients were categorized into two groups based on their treatment modality: the THA group (n=45, treated with THA) and the PFNA group (n=41, treated with PFNA internal fixation). The two groups were compared in terms of surgery-related indicators (operative time, incision length, intraoperative blood loss, postoperative drainage volume, and intraoperative fluoroscopy frequency), postoperative recovery indicators (time to first ambulation, length of stay, time until full weight-bearing ambulation), and the incidence of postoperative complications. The pain indicators (Wong-Baker Faces Pain Rating Scale) and hip joint function indicators (Harris Hip Scores) of patients in the two groups were assessed preoperatively and at 1, 3, and 6 months postoperatively. The hip joint function recovery outcomes of the two groups of patients were recorded at the last follow-up. The PFNA group had significantly shorter operative time, shorter incision length, lower intraoperative blood loss, lower postoperative drainage volume, and higher intraoperative fluoroscopy frequency compared to the THA group (all P < 0.05). The PFNA group also had significantly longer time to first ambulation, length of stay, and time until full weight-bearing ambulation (all P < 0.05). There was no statistically significant difference in the incidence of postoperative complications between the two groups (P > 0.05). Postoperative Wong-Baker scores in both groups decreased compared to preoperative levels. At 1 and 3 months postoperatively, the PFNA group had significantly higher Wong-Baker scores than the THA group (P < 0.05), but at 6 months postoperatively, the difference was not statistically significant (P > 0.05). Postoperative Harris scores increased in both groups compared to preoperative scores. At 1 month postoperatively, the PFNA group had significantly lower Harris scores than the THA group (P < 0.05); however, at 3 and 6 months postoperatively, the differences were not statistically significant (all P > 0.05). There was no significant difference in the rates of excellent recovery of hip joint function between the two groups at the last follow-up (P > 0.05). Both THA and PFNA internal fixation yield favorable outcomes in treating IFF with no significant difference in complications. The difference lies in the shorter operative time and lesser trauma inflicted by PFNA internal fixation, despite it involving prolonged radiation exposure and bed rest. Conversely, THA requires longer operative time and causes greater trauma but results in shorter postoperative recovery periods, allowing earlier ambulation.

Staple Line Reinforcement Using SEAMGUARD® versus Suture Over Sewing During Laparoscopic Sleeve Gastrectomy for Super Morbidly Obese Patients: A Prospective Randomized Clinical Trial.

A prospective randomized clinical trial included 200 super morbidly obese patients randomized into two groups: Group 1 with reinforcement of the staple line by SEAMGUARD® (Gore Medical, Newark, Delaware) and Group 2 with reinforcement of the staple line using suture over sewing. The mean operative time was significantly shorter in Group 1 than Group 2 (62.6 ± 14.5 vs. 84.7 ±15.8 min, p=0.02). Intraoperative blood loss was significantly lower in Group 1 than Group 2 (17.1± 19.1 vs. 56.8 ± 27.9ml, p=0.00). Staple line hematomas were significantly higher in Group 2. There was no difference in postoperative bleeding between the two groups. No leak was reported in both groups. The cost was higher in Group 1. Reinforcing the staple line in laparoscopic sleeve gastrectomy using suturing is equal to SEAMGUARD® in all aspects except shorter operative time and lower intraoperative blood loss with SEAMGUARD®.

A Comparison of Hidden Blood Loss Between Multilevel Posterior Lumbar Interbody Fusion and Lateral Lumbar Interbody Fusion in Adult Spinal Deformity Patients.

Retrospective cohort study. This study aimed to compare transfusion and blood loss volumes, particularly hidden blood loss volume, in adult spinal deformity patients undergoing lateral lumbar interbody fusion (LLIF) and posterior lumbar interbody fusion (PLIF). Corrective surgery for adults with spinal deformity patients can be performed via the traditional posterior approach (PLIF) or minimally invasive lateral approach (LLIF). LLIF is associated with longer or comparable operation times and lower intraoperative blood loss. However, hidden blood loss has not been compared between the two procedures. We compared hidden blood loss and other blood loss volumes, transfusion volume, operation time, and radiographic surgical outcomes between LLIF patients (n = 71) and PLIF patients (n = 33) who underwent surgery in our institution from September 2011 to June 2018. All patients provided informed consent in accordance with the Declaration of Helsinki. Institutional ethics committee conducted this study approval was obtained. Transfusion volume and intraoperative and total blood loss volumes were significantly higher in the PLIF group. Operation time and HBL did not significantly differ. The hidden blood loss-to-intraoperative blood loss ratio was significantly higher in the LLIF group (113% vs 60%; P = .004). Radiographic measures of outcome were significantly better after surgery than before in both groups. Although intraoperative blood loss was less with LLIF than PLIF, HBL was similar between the approaches. Patients undergoing LLIF should be followed closely for postoperative anemia even if intraoperative blood loss is low.

Functional outcome of supracondylar fracture femur treated with plate fixation and retrograde intramedullary nailing – A comparative study

Fractures of distal femur reportedly account for less than 1% of all fractures and about 4% of all femur fractures. Aims of the treatment of extra-articular fractures are restoration of length, torsion, and frontal and sagittal plane alignment and stable fixation. The objective of the study is to compare the functional and radiological outcome of the patients who sustained the distal femoral fractures treated with plate fixation against retrograde intramedullary nail. Patients meeting the specified inclusion criteria were divided into two groups: one treated with retrograde intramedullary nailing and the other with plate fixation. Follow-up assessments were performed at 4, 12, and 24 weeks post-surgery, utilizing flexion scores and Modified Schatzker and Lambert criteria to evaluate functional and radiological outcomes. The functional outcomes and knee flexion scores at the 6-month mark showed no significant difference between the plating and nailing groups. However, the plating group demonstrated early recovery, with a significant improvement in range of motion observed at 4 weeks post-operation. Retrograde intramedullary nailing exhibited advantages in terms of shorter surgery duration and lower intraoperative blood loss, making it a preferred option for patients with anticipated major blood loss or polytraumatized individuals.

Clinical outcomes of modified direct lateral approach of Hardinge for total hip arthroplasty.

The aim of the study was to evaluate a modified direct lateral approach for total hip arthroplasty in terms of clinical and functional outcomes, rate of complications and hospitalization. We retrospectively reviewed the data of 526 patients with THA operated in our department between January 2017 and December 2021. Clinical examination, functional outcome and radiographic evaluation were performed during follow-up. Patients were evaluated at the following time points: preoperatively and postoperatively at 3 days, 6 weeks, 12 weeks and 1 year and we registered surgery related data, complications, Visual Analogue Scale pain score, Harris Hip Score, the Western Ontario McMaster Osteoarthritis Index. Low intraoperative blood loss, short operation time, short hospitalization, early mobilization of the patient and good range of motion imposed the modified direct lateral approach as a valuable procedure for the patients with THA. VAS score evaluated at 3 days and 6 weeks indicated a very good overall postoperative experience. The HHS and Womac scores were evaluated at 6 weeks, 12 weeks and 1 year and showed excellent results. Trendelenburg gait and abductor weakness, traditionally related with direct lateral approach, were not significant statistically and complete reversible. We registered a very low complication rates with good functional outcome. The modified direct lateral approach can lead to superior outcomes, improved quality of life, with reduced intra and postoperative complications rate.

Minimally Invasive Surgery for Posterior Spinal Instrumentation and Fusion in Adolescent Idiopathic Scoliosis: Current Status and Future Application.

The posterior minimally invasive spine surgery (MISS) approach-or the paraspinal muscle approach-for posterior spinal fusion and segmental instrumentation in adolescent idiopathic scoliosis (AIS) was first reported in 2011. It is less invasive than the traditionally used open posterior midline approach, which is associated with significant morbidity, including denervation of the paraspinal muscles, significant blood loss, and a large midline skin incision. The literature suggests that the MISS approach, though technically challenging and with a longer operative time, provides similar levels of deformity correction, lower intraoperative blood loss, shorter hospital stays, better pain outcomes, and a faster return to sports than the open posterior midline approach. Correction maintenance and fusion rates also seem to be equivalent for both approaches. This narrative review presents the results of relevant publications reporting on spinal segmental instrumentation using pedicle screws and posterior spinal fusion as part of an MISS approach. It then compares them with the results of the traditional open posterior midline approach for treating AIS. It specifically examines perioperative morbidity and radiological and clinical outcomes with a minimal follow-up length of 2 years (range 2-9 years).

Efficacy of Augmented Reality Combined with Indocyanine Green Fluorescence Imaging Guided Laparoscopic Segmentectomy for Hepatocellular Carcinoma.

The internal anatomy of the liver is extremely complex. Laparoscopic anatomical segmentectomy requires reference to the position and alignment of intrahepatic vascular. However, the surface of the liver lacks anatomical landmarks and the liver segment boundaries cannot be identified with the naked eye. Augmented reality navigation (ARN) and indocyanine green fluorescence imaging (FI) are emerging navigation tools in liver resection. This study aimed to explore the efficacy and application value of laparoscopic anatomical segmentectomy guided by ARN combined with indocyanine green FI. Ninety-eight patients who were diagnosed with hepatocellular carcinoma and underwent laparoscopic anatomical segmentectomy from January 2018 to January 2022 were retrospectively analyzed. They were divided into the ARN-FI group (45 patients) and the non-ARN-FI group (53 patients) based on whether ARN combined with FI was applied during the operation. The differences in intraoperative and postoperative outcomes were compared. There was no significant difference in preoperative baseline data and postoperative complication rates between the 2 groups. Compared with the non-ARN-FI group, the ARN-FI group had much lower intraoperative blood loss (100 vs 200 mL, p = 0.005) and a lower incidence of remnant liver ischemia (13.3% vs 30.2%, p = 0.046). The 1- and 3-year disease-free survival rates in the ARN-FI and non-ARN-FI groups were 91.01% vs 71.15% and 70.01% vs 52.46%, respectively; the differences between the 2 groups were statistically significant (p = 0.047). The ARN-FI technology provides a more standardized approach for liver parenchyma section during laparoscopic liver resection, effectively minimizing intraoperative blood loss, reducing postoperative remnant liver ischemia, and improving oncological prognosis. This method is safe and feasible and has good clinical application prospects.
