Single-Level Endoscopic TLIF Has Decreased Surgery Duration, Blood Loss, and Length of Hospital Stay While Achieving Similar 1-Year Clinical and Radiological Outcomes Compared With Conventional Minimally Invasive TLIF.

This study presents a single surgeon's experience comparing 1-year outcomes of endoscopic transforaminal lumbar interbody fusion (E-TLIF) vs minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in an Asian population. Retrospective review of consecutive patients who underwent single-level E-TLIF or MIS-TLIF by a single surgeon in a tertiary spine institution from 2018 to 2021 with 1-year follow-up. Inclusion criteria for both procedures were degenerative disc disease with grade I or II spondylolisthesis and mild to moderate central canal stenosis. Clinical outcomes assessed included surgery duration, blood loss, and length of stay. Patient-reported outcomes assessed included the visual analog score for back pain and lower limb pain, Oswestry Disability Index, and North American Spine Society Neurogenic Symptom Score. Radiographic parameters assessed included segmental lordosis, posterior disc height, listhesis, and the presence of cage migration or subsidence. Twelve E-TLIF and 34 MIS-TLIF patients were identified. E-TLIF had shorter surgery duration (165 ± 15 vs 259 ± 43 min for E-TLIF and MIS-TLIF groups, respectively; P < 0.001), reduced blood loss (83 ± 75 vs 181 ± 225 mL; P = 0.033), and decreased length of stay (1.8 ± 0.9 vs 4.7 ± 2.9 days; P < 0.001) compared with MIS-TLIF. E-TLIF and MIS-TLIF patients had significant improvements (P < 0.05) at 1 year in all patient-reported outcomes scores and radiographic parameters assessed. Both E-TLIF and MIS-TLIF patient groups also had similar postoperative patient-reported outcomes scores and radiographic parameters. No complications were recorded for E-TLIF, while MIS-TLIF had a case of dura tear and another case of meralgia paresthetica. There were no instances of cage subsidence, cage migration, or implant loosening in either group at 1 year. Although the study size was limited because E-TLIF is a relatively new technique in our institution, 1-year results demonstrate that E-TLIF can be a safe and efficacious option that achieves clinical and radiological results similar to MIS-TLIF with the additional benefits of decreased surgical duration, blood loss, and length of hospital stay. The results of this study support the effectiveness and potential advantages of endoscopic TLIF compared with MIS-TLIF.

Comparison of unilateral and bilateral percutaneous kyphoplasty for the treatment of osteoporotic vertebral compression fractures associated with scoliosis.

To assess the clinical and radiographic effectiveness of unilateral and bilateral percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fractures (OVCF) associated with scoliosis, 52 patients with OVCF associated with scoliosis who underwent PKP were retrospectively analysed. The patients were divided into the unilateral PKP group (n=26) and the bilateral PKP group (n=26). The operation time, bone cement injection volume and frequency of intraoperative fluoroscopy were recorded and compared between the groups. Additionally, visual analogue scale (VAS) and Oswestry disability index (ODI) scores, as well as postoperative complications, including bone cement leakage and adjacent vertebral fractures, were also assessed. The operation time, bone cement injection volume and intraoperative fluoroscopy frequency were significantly lower in the unilateral compared with the bilateral group (P<0.001). The VAS score, ODI score, average vertebral body height and kyphotic angle (KA) were improved after surgery in each group with no difference in these clinical parameters between the two groups both before and after surgery. Furthermore, the proportion of cases with bone cement leakage in the unilateral group was significantly lower compared with that in the bilateral group (P<0.05). During the follow-up, there were three cases (11.5%) in the unilateral group and two cases (7.7%) in the bilateral group who suffered adjacent vertebral fractures, but there was no statistically significant difference between the two groups (P>0.05). For treating patients with OVCF accompanied by scoliosis, both unilateral and bilateral PKP could effectively relieve the acute back pain and correct the KA. However, unilateral PKP presents more advantages, such as a short operation duration and reduced intraoperative fluoroscopy frequency and bone cement leakage.

Comparison of tragal perichondrium and COOK artificial material in endoscopic type 1 tympanoplasty

ObjectiveVarious materials have been used for tympanic membrane reconstruction in middle ear surgery. This study aimed to evaluate the difference between the tragal perichondrium and COOK artificial material in patients who underwent endoscopic type 1 tympanoplasty. MethodThis retrospective study included patients who underwent endoscopic type 1 tympanoplasty from June 2021 to June 2022 at Sir Run Run Shaw Hospital, Zhejiang University School of Medicine. Patients were divided into group A (tragal perichondrium) and group B (COOK artificial material) according to the material used in the operation. All patients were followed up for 6 months. The differences in age, gender, operation site, disease course, preoperative air-bone gap (ABG), operation time, blood loss, hearing gain, and wound healing rate were compared between the two groups. ResultsThis study enrolled 197 patients, with 120 patients in group A and 77 patients in group B. There were no significant differences in age, gender, operation site, disease course, or preoperative ABG between groups A and B (p > 0.05). Both groups had significant postoperative improvement in hearing (group A: 30.98 ± 9.58 dB vs. 17.07 ± 9.92 dB, p < 0.001; group B: 29.75 ± 7.52 dB vs. 14.25 ± 9.07 dB, p < 0.001). The mean hearing gain in group A and group B was comparable (14.02 ± 11.91 dB vs. 15.50 ± 7.05 dB, p = 0.609). The wound healing rates of groups A and B were no differences (93.33% vs. 87.01%, p = 0.133). The patients in group B had a shorter operation duration (72.57 ± 11.32 min vs. 61.86 ± 9.27 min, p = 0.045) and less blood loss (12.38 ± 3.7 mL vs. 8.10 ± 2.43 mL, p = 0.004). ConclusionsTragal perichondrium and COOK artificial material are reliable for functional and anatomical outcomes in endoscopic type 1 tympanoplasty, and COOK artificial material can save operation time and blood loss in surgery compared to the tragal perichondrium.

The Use of Keystone Flap for the Reconstruction of Skin Defects

Background and objectives: Skin graft and various flaps are used to cover defects; available options have different patterns of blood supply, aesthetic outcome, donor area morbidity, surrounding soft tissue availability, operative time duration, the need for microsurgical expertise and long term complications. The aim of this study is to assess reliability and versatility of keystone flap for the reconstruction of the skin defects. Methods: Reconstruction of skin defects by keystone flap were done in plastic surgery department between (January 2018- May 2020), records of patient’s age, and cause of the defect, size, flap outcome and complications are documented.to study the ability of the flap to cover the skin defect and its long term survival. Results: Nineteen patients underwent reconstruction, age was ranging from two days to seventy-five-year-old with mean age 37.5 years, twelve were males and seven were females. Size of the defect ranged from (0.5 cm x 1 cm) to (9 cm x 7 cm) with mean defect size 31.75 cm2. Seven flaps in head and neck, five in the trunk, five in lower limb and two flaps in upper limb. All flaps were successful in covering the defects, no partial or total necrosis with minor complication in two patients. Conclusions: Keystone flap is a reliable flap with excellent survival rate, versatile and can be used for skin defects in different regions of the body with low complication rate, easy technique for learning by surgeons and have short operative duration with good cosmetic outcome.

Comparative study of onlay versus sublay mesh repair in the management of ventral hernias.

Ventral hernias with large defects (≥ 2cm) are managed with tension free mesh repair. The growing consensus that sublay (retrorectus) mesh repair is superior to onlay mesh repair due to fewer complications is based on literature dominated by retrospective studies from high and upper-middle income countries. There is thus a need of more prospective studies from various countries to resolve the controversy. The objective of this study was to compare the outcomes of onlay versus sublay mesh repair in the management of ventral hernias. Our single centre, prospective comparative study set in a low-middle income country comprised of 60 patients with a ventral hernia undergoing open surgical repair using either onlay technique (n = 30) or sublay technique (n = 30). Surgical site infections, seroma formation, recurrence were found in 3.33%, 6.67%, 0% patients in sublay repair group and in 16.67%, 20%, 6.67% patients in onlay repair group respectively. Mean duration of surgery, mean Visual Analogue Scale (VAS) score for chronic pain, mean duration of hospital stay were 46min, 4.5, 8days in onlay repair group and 61min, 4.2, 6days in sublay repair group respectively. Onlay repair group was associated with shorter duration of surgery. However, sublay repair was associated with lesser rates of surgical site infections, chronic pain and recurrence than onlay repair. Sublay mesh repair had better outcomes than onlay mesh repair for the management of ventral hernias, however superiority of any one technique could not be established.

Uniportal versus multiportal nonintubated thoracoscopic anatomical resection for lung cancer: A propensity-matched analysis

No studies have compared between uniportal and multiportal nonintubated thoracoscopic anatomical resection for non-small cell lung cancer (NSCLC). We aimed to compare short- and long-term postoperative outcomes concerning these two methods.Our retrospective dataset comprised patients with NSCLC who underwent uniportal or multiportal nonintubated thoracoscopic anatomical resection between January 2011 and December 2019. The primary outcome was recurrence-free survival. Propensity scores were matched according to age, sex, body mass index, pulmonary function, tumor size, cancer stage, and surgical method.In total, 1130 such patients underwent nonintubated video-assisted thoracoscopic surgery (VATS), and 490 consecutive patients with stage I-III NSCLC underwent nonintubated anatomical resection, including lobectomy and segmentectomy (uniportal, n = 158 [32.3%]; multiportal, n = 331 [67.7%]). The uniportal group had fewer dissected lymph nodes and lymph node stations. In paired group analysis, the uniportal group had shorter operation durations (99.8 vs. 138.2 min; P < 0.001), lower intensive care unit (ICU) admission rates and ICU admission intervals (7.0% vs. 27.8%; P < 0.001), and shorter postoperative hospital stays (4.1 days vs. 5.2 days; P < 0.001). The most common postoperative complication was prolonged air leaks. No surgical mortality was observed. The multiportal group had higher complication rates for grades ≥ II NSCLC; however, this difference was not significant (4.4% vs. 1.3%, respectively; P = 0.09).Nonintubated uniportal VATS for anatomical resection had better results for some perioperative outcomes than multiportal VATS. Oncological outcomes such as recurrence-free and overall survival remained uncompromised, despite fewer dissected lymph nodes.

Risk factors for revision due to prosthetic joint infection following total knee arthroplasty based on 62,087 knees in the Finnish Arthroplasty Register from 2014 to 2020

Periprosthetic joint infection (PJI) is the commonest reason for revision after total knee arthroplasty (TKA). We assessed the risk factors for revision due to PJI following TKA based on the Finnish Arthroplasty Register (FAR). We analyzed 62,087 primary condylar TKAs registered between June 2014 and February 2020 with revision for PJI as the endpoint. Cox proportional hazards regression was used to estimate hazard ratios (HR) with 95% confidence intervals (CI) for the first PJI revision using 25 potential patient- and surgical-related risk factors as covariates. 484 knees were revised for the first time during the first postoperative year because of PJI. The HRs for revision due to PJI in unadjusted analysis were 0.5 (0.4-0.6) for female sex, 0.7 (0.6-1.0) for BMI 25-29, and 1.6 (1.1-2.5) for BMI > 40 compared with BMI < 25, 4.0 (1.3-12) for preoperative fracture diagnosis compared with osteoarthritis, and 0.7 (0.5-0.9) for use of an antimicrobial incise drape. In adjusted analysis the HRs were 2.2 (1.4-3.5) for ASA class III-IV compared with class I, 1.7 (1.4-2.1) for intraoperative bleeding ≥ 100 mL, 1.4 (1.2-1.8) for use of a drain, 0.7 (0.5-1.0) for short duration of operation of 45-59 minutes, and 1.7 (1.3-2.3) for long operation duration > 120 min compared with 60-89 minutes, and 1.3 (1.0-1.8) for use of general anesthesia. We found increased risk for revision due to PJI when no incise drape was used. The use of drainage also increased the risk. Specializing in performing TKA reduces operative time and thereby also the PJI rate.

Primary Cooperative Application of a LARS® Tube and 3D‐Printed Prosthesis for Reconstruction of the Distal Radius after en bloc Resection of Giant Cell Tumor of Bone: A Comparative Retrospective Study

Using a fibula autograft (FA) to reconstruct defects after en bloc resection of giant cell tumor of bone (GCTB) in the distal radius is classic but has high complication rates. We describe a novel reconstruction method employing the cooperative application of LARS® and a 3D-printed prosthesis (L-P) and investigate whether it improves postoperative outcomes. From April 2015 to August 2022, 14 patients who underwent the cooperative L-P reconstruction method after en bloc resection of distal radial GCTBs and 31 patients who received FA reconstruction were enrolled as two retrospective cohorts in this comparative study. The properties of the implants and critical surgical techniques were elaborated in the L-P group. Preoperative function, intraoperative data, and postoperative clinical, functional, and radiographic outcomes of all patients were recorded and compared between the two groups. The grip strength and range of wrist motion, including extension, flexion, radial deviation, and ulnar deviation, were measured. The Mayo modified wrist and Musculoskeletal Tumor Society scores were chosen to assess wrist function and surgical functional outcomes, respectively. Kaplan-Meier curves were generated to analyze the significant differences in complication rates and implant survival between the two groups. In both groups, all 45 patients underwent the operation without complication with similar average osteotomy lengths and bleeding volumes, while a shorter operative duration was achieved in the L-P group (201.43 ± 22.87 min vs. 230.16 ± 51.44 min, P=0.015). At a mean follow-up of 40.42 ± 18.43months (range, 14-72months), both reconstruction methods effectively ameliorated postoperative function. Patients who received L-P showed higher postoperative modified Mayo wrist scores (81.43 ± 5.49 vs. 71.13 ± 16.10, P=0.003), Musculoskeletal Tumor Society scores (27.64 ± 1.34 vs. 25.06 ± 2.95, P=0.004), and grip strength on the normal side (68.71% ± 8.00% vs. 57.81% ± 12.31%, P=0.005) than the FA group. Better wrist extension (63.21° ± 8.99° vs. 45.32° ± 14.53°, P < 0.001) and flexion (45.36° ± 7.90° vs. 30.48° ± 12.07°, P < 0.001) were also observed in the L-P group. The complication rate was significantly higher in the FA group (29/31, 93.55%) than in the L-P group (1/14 7.14%, P < 0.001). The L-P group showed higher implant survival than the FA group, but the difference was not statistically significant. The cooperative application of LARS® and 3D-printed prostheses is an effective modality for reconstructing musculoskeletal defects after en bloc resection of distal radial GCTBs, which can improve functional outcomes, diminish complication rates, and promote wrist joint stability and motion.

Biological plating for diaphyseal humeral fractures

Background Diaphyseal humeral fracture is one of the common injuries in orthopedic surgery. The biological plating technique or minimally invasive plate osteosynthesis (MIPO) is the fixation of the fracture with minimal opening, preserving the soft tissue attachment and blood supply to the bone. Aim To evaluate the biological plating technique in the management of diaphyseal humeral fractures by comparing MIPO with open reduction and internal fixation (ORIF) techniques. Patients and methods This study is a randomized controlled trial. It was performed on 40 adult patients with a humeral diaphyseal fracture. The patients were randomly divided into two groups: 20 MIPO cases and 20 ORIF controls. We compared the two groups. Results MIPO is superior to ORIF, as it has a shorter duration of surgery, shorter incision length, and less blood loss. It may minimize to some extent the duration of fracture healing and the risk of deep infection. MIPO and ORIF have excellent shoulder and elbow functional outcomes. Conclusion MIPO offers many advantages over the ORIF, but it has some disadvantages.

A Multicenter, Propensity Score-Matched Assessment of Endoscopic Versus Microscopic Approaches in the Management of Pituitary Adenomas.

There is considerable controversy as to which of the 2 operating modalities (microsurgical or endoscopic transnasal surgery) currently used to resect pituitary adenomas (PAs) is the safest and most effective intervention. We compared rates of clinical outcomes of patients with PAs who underwent resection by either microsurgical or endoscopic transnasal surgery. To independently assess the outcomes of each modality type, we sought to isolate endoscopic and microscopic PA surgeries with a 1:1 tight-caliper (0.01) propensity score-matched analysis using a multicenter, neurosurgery-specific database. Surgeries were performed between 2017 and 2020, with data collected retrospectively from 12 international institutions on 4 continents. Matching was based on age, previous neurological deficit, American Society of Anesthesiologists (ASA) score, tumor functionality, tumor size, and Knosp score. Univariate and multivariate analyses were performed. Among a pool of 2826 patients, propensity score matching resulted in 600 patients from 9 surgery centers being analyzed. Multivariate analysis showed that microscopic surgery had a 1.91 odds ratio (OR) ( P = .03) of gross total resection (GTR) and shorter operative duration ( P < .01). However, microscopic surgery also had a 7.82 OR ( P < .01) for intensive care unit stay, 2.08 OR ( P < .01) for intraoperative cerebrospinal fluid (CSF) leak, 2.47 OR ( P = .02) for postoperative syndrome of inappropriate antidiuretic hormone secretion (SIADH), and was an independent predictor for longer postoperative stay (β = 2.01, P < .01). Overall, no differences in postoperative complications or 3- to 6-month outcomes were seen by surgical approach. Our international, multicenter matched analysis suggests microscopic approaches for pituitary tumor resection may offer better GTR rates, albeit with increased intensive care unit stay, CSF leak, SIADH, and hospital utilization. Better prospective studies can further validate these findings as matching patients for outcome analysis remains challenging. These results may provide insight into surgical benchmarks at different centers, offer room for further registry studies, and identify best practices.

Factors for Prolonged Pain and Restriction of Movement Following Hemiepiphysiodesis Plating for the Correction of Lower Limb Malalignment in the Frontal Plane: An Explorative Analysis.

The correction of valgus leg malalignment in children using implant-mediated growth guidance is widely used and effective. Despite the minimal invasive character of the procedure, a relevant number of patients sustain prolonged pain and limited mobility after temporary hemiepiphysiodesis. Our aim was to investigate implant-associated risk factors (such as implant position and screw angulation), surgical- or anesthesia-related risk factors (such as type of anesthesia, use, and duration), and pressure of tourniquet or duration of surgery for these complications. Thirty-four skeletally immature patients with idiopathic valgus deformities undergoing hemiepiphysiodesis plating from October 2018-July 2022 were enrolled in this retrospective study. Participants were divided into groups with and without prolonged complications (persistent pain, limited mobility of the operated knee between five weeks and six months) after surgery. Twenty-two patients (65%) had no notable complications, while twelve patients (35%) had prolonged complications. Both groups differed significantly in plate position relative to physis (p = 0.049). In addition, both groups showed significant differences in the distribution of implant location (p = 0.016). Group 1 had a shorter duration of surgery than group 2 (32 min vs. 38 min, p = 0.032) and a lower tourniquet pressure (250 mmHg vs. 270 mmHg, p = 0.019). In conclusion, simultaneous plate implantation at the femur and tibia and metaphyseal plate positioning resulted in prolonged pain and a delay of function. In addition, the amplitude of tourniquet pressure or duration of surgery could play a factor.

Perioperative safety and prognosis following parenchyma-preserving surgery for solid pseudopapillary neoplasm of the pancreas

Background/objectivesTo evaluate perioperative safety and outcome of parenchyma-preserving pancreatectomy and risk factors of metastasis and recurrence for patients with solid pseudopapillary neoplasm (SPN).MethodsDemographic data, operative and pathological parameter, follow-up data of patients with SPN undergoing their first operation were collected in our single center from May 2016 to October 2021 and compared between regular pancreatectomy group and parenchyma-preserving surgery group. Risk factors for metastasis and recurrence were investigated.ResultsA total of 194 patients were included, 154 of whom were female and the average age of all patients was 33 years old. Most patients were asymptomatic, with the most common complaint being abdominal pain or discomfort. Of them, 62 patients underwent parenchyma-preserving pancreatectomy including middle segment pancreatectomy and enucleation, and 132 patients underwent regular pancreatectomy including pancreaticoduodenectomy, distal pancreatectomy and total pancreatectomy. Patients in the parenchyma-preserving surgery group had a shorter duration of operation, less intraoperative bleeding, and decreased risk of combined organ removal and blood transfusion, with no statistical significance yet. The two groups exhibited a similar incidence of postoperative complications including grade B and C pancreatic fistula, delayed gastric emptying, postoperative pancreatic hemorrhage, and other complications, as well as radiological intervention, relaparotomy and the length of postoperative hospital stay. There were no perioperative deaths. All the patients, except 18 of those who discontinued follow-up, were alive with a median follow-up time of 31 months. Three patients in the regular pancreatectomy group were observed to have liver metastasis, and no metastasis was observed in the parenchyma-preserving surgery group. Significant risk factors for tumor metastasis and recurrence were tumor size, angioinvasion, and nerve infiltration.ConclusionsParenchyma-preserving surgery did not significantly increase the frequency of perioperative complications or recurrence and might be preferable if comprehensive conditions allow.

Comparison of the short-term efficacy and safety of bipolar transurethral electro vaporization and holmium laser enucleation of the prostate for moderate and large benign prostatic enlargement

BackgroundTo compare the efficacy and safety of bipolar transurethral vaporization of the prostate (B-TUVP) with holmium laser enucleation of the prostate (HoLEP) for moderate [prostate volume (PV) 30–80 ml] and large (≥ 80 ml) benign prostatic enlargement (BPE).Materials and methodsMale patients with lower urinary tract symptom (LUTS) or urinary retention who underwent B-TUVP or HoLEP treatment in two regional centers were respectively enrolled. Patient characteristics and treatment outcomes were retrospectively compared between B-TUVP and HoLEP.ResultsIn patients with moderate and large prostate volume,B-TUVP showed shorter operative time (P < 0.001) and less hemoglobin decrease (P < 0.001) than in HoLEP. In uncatheterised patients, voiding symptoms and patients’ quality of life improved after B-TUVP and HoLEP, but these improvement rates were consistently bigger in HoLEP than in B-TUVP. In catheterised patients, the rate of achieving catheter-free status after surgery was higher in HoLEP than in B-TUVP for patients with PV > 80 ml.(P < 0.001) The incidence of postoperative fever was higher in B-TUVP than in HoLEP for patients with PV 30–80 ml (P < 0.001) but not for those with PV > 80 ml.(P=0.08) The Incidence of postoperative stress incontinence(SUI) was higher in HoLEP than in B-TUVP for patients with moderate and large prostate volume.ConclusionsThere are few studies that investigated the short-term efficacy and safety of second-generation B-TUVP in comparison with HoLEP for moderate and large BPE. Improvement in LUTS and achievement of catheter-free status were predominant in HoLEP, and these outcomes were more prominent in patients with large BPE of PV > 80 ml. However, B-TUVP resulted in less blood loss, shorter operative duration, and less SUI suggesting that B-TUVP is also well-tolerated surgical modality.

Neurosurgeons Deliver Similar Quality Care Regardless of First Assistant Type: Resident Physician versus Nonphysician Surgical Assistant

There are limited data evaluating the outcomes of attending neurosurgeons with different types of first assistants. This study considers a common neurosurgical procedure (single-level, posterior-only lumbar fusion surgery) and examines whether attending surgeons deliver equal patient outcomes, regardless of the type of first assistant (resident physician vs. nonphysician surgical assistant [NPSA]), among otherwise exact-matched patients. The authors retrospectively analyzed 3395 adult patients undergoing single-level, posterior-only lumbar fusion at a single academic medical center. Primary outcomes included readmissions, emergency department visits, reoperation, and mortality within 30 and 90days after surgery. Secondary outcome measures included discharge disposition, length of stay, and length of surgery. Coarsened exact matching was used to match patients on key demographics and baseline characteristics known to independently affect neurosurgical outcomes. Among exact-matched patients (n=1402), there was no significant difference in adverse postsurgical events (readmission, emergency department visits, reoperation, or mortality) within 30days or 90days of the index operation between patients who had resident physicians and those who had NPSAs as first assistants. Patients who had resident physicians as first assistants demonstrated a longer length of stay (mean: 100.0 vs. 87.4hours, P<0.001) and a shorter duration of surgery (mean: 187.4 vs. 213.8minutes, P<0.001). There was no significant difference between the two groups in the percentage of patients discharged home. For single-level posterior spinal fusion, in the setting described, there are no differences in short-term patient outcomes delivered by attending surgeons assisted by resident physicians versus NPSAs.

General Anesthesia Versus Regional Anesthesia in the Elderly Patients Undergoing Hip Fracture Surgeries: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

Surgery is the preferred treatment option for the elderly patients with hip fractures. However, the choice of general anesthesia (GA) or regional anesthesia (RA) remains controversial. The quality of evidence has further improved with the advent of several high-quality randomized clinical trials (RCTs) in the last two years. The purpose of this study was to compare the clinical outcomes of two anesthetic techniques in elderly patients undergoing hip fracture surgeries. Eligible studies were identified from PubMed/MEDLINE, Web of Science, Scopus, EMBASE and reference lists from January 2000 to June 2022 in this current systematic review and meta-analysis. The outcomes included the surgery-related outcomes (duration of surgery, duration of anesthesia, intraoperative blood loss and number of transfusions) and postoperative outcomes (30-day mortality, postoperative delirium,cardiovascular events and other complications). A total of 10 RCTs were included, and a total of 3594 patients were analyzed. RA was associated with shorter duration of surgery, shorter length of hospital stays and less intraoperative blood loss compared to GA. There were no significant differences between the two groups in the number of blood transfusions, duration of anesthesia, 30-day mortality or postoperative delirium. Our pooled analysis identified no significant differences in terms of the safety between RA and GA, while RA reduces intraoperative blood loss, length of hospital stays and duration of surgery. These results suggest that RA appears to be preferable for the elderly patients with hip fractures.

Measurement of Postoperative Quality of Pain in Abdominoplasty Patients—An Outcome Oriented Prospective Study

(1) Background: Postoperative pain is a frequently underestimated complication significantly influencing surgical outcome and patient satisfaction. While abdominoplasty is one of the most commonly performed plastic surgery procedures, studies investigating postoperative pain are limited in current literature. (2) Methods: In this prospective study, 55 subjects who underwent horizontal abdominoplasty were included. Pain assessment was performed by using the standardized questionnaire of the Benchmark Quality Assurance in Postoperative Pain Management (QUIPS). Surgical, process and outcome parameters were then used for subgroup analysis. (3) Results: We found a significantly decreased minimal pain level in patients with high resection weight compared to the low resection weight group (p = 0.01 *). Additionally, Spearman correlation shows significant negative correlation between resection weight and the parameter "Minimal pain since surgery" (rs = -0.332; p = 0.013). Furthermore, average mood is impaired in the low weight resection group, indicating a statistical tendency (p = 0.06 and a Χ2 = 3.56). We found statistically significant higher maximum reported pain scores (rs = 0.271; p = 0.045) in elderly patients. Patients with shorter surgery showed a statistically significant (Χ2 = 4.61, p = 0.03) increased claim for painkillers. Moreover, "mood impairment after surgery" shows a dramatic trend to be enhanced in the group with shorter OP duration (Χ2 = 3.56, p = 0.06). (4) Conclusions: While QUIPS has proven to be a useful tool for the evaluation of postoperative pain therapy after abdominoplasty, only continuous re-evaluation of pain therapy is a prerequisite for constant improvement of postoperative pain management and may be the first approach to develop a procedure-specific pain guideline for abdominoplasty. Despite a high satisfaction score, we detected a subpopulation with inadequate pain management in elderly patients, patients with low resection weight and a short duration of surgery.

The results of concentration of care: Surgical outcomes of neuroblastoma in the Netherlands.

In the Netherlands pediatric oncological care for solid tumours is concentrated in one centre since November 2014. One of the most frequently diagnosed solid non-brain tumours in children is the neuroblastoma. Results of surgical treatment of neuroblastoma since the start of this centralization are presented and compared to a historic cohort. The new national cohort of neuroblastoma (n=111) consists of all consecutive patients treated between January 1st, 2015 and April 1st, 2021. The historic neuroblastoma cohort consists of all operated neuroblastoma patients in the Netherlands between 1998 and 2014 (n=244). Intra-operative complications and surgical outcome were registered. Post-operative complications were divided in short (<30 days after surgery) and long term (>30 days). The severity of complications was graded using the Clavien Dindo Classification (CDC) system. Intraoperative outcomes showed significant differences in favour of the new cohort with less blood loss (p<0.001), fewer vascular complications (p<0.001) and shorter duration of surgery (p<0.001). Short term complications were comparable in numbers, but significantly more patients had CDC grade 3/4/5 complications in the historic cohort (p=0.005). Long term complications did not differ. Estimated overall survival showed a better survival in the new cohort (log rank 0.022). Centralization of care for neuroblastoma patients has led to a significant improvement of both intraoperative outcomes and short term complications.

SURGICAL MANAGEMENT OF BILATERAL INGUINAL HERNIAS: A PROSPECTIVE STUDY OF LICHTENSTEIN, STOPPAS AND TEP REPAIR.

BACKGROUND: The choice of surgery for bilateral inguinal hernia repair still remains a debatable question for surgeons. This study was aimed at analysing the effectives as well as comparing Lichtenstein, Stoppas and laparoscopic TEP(total extraperitoneal repair) approaches for Bilateral inguinal hernia. Prospective study invol MATERIALS AND METHODS: ving 60 patients of Bilateral inguinal hernia, were divided into 3 groups, 20 patients each in Lichtenstein, Stoppas and TEP. As per relevant rating scales, parameters analysed were duration of surgery, post operative pain, post operative analgesia requirement, duration of hospital stay, return to normal activity, cost effectiveness, surgical complications, recurrence over 6months. Minor complications such as seroma, scrotal RESULTS: oedema, wound infection were common in Lichtenstein compared to Stoppas and TEP. Shorter duration of surgery, early discharge and early return to normal activities was seen in Stoppas and TEP compared to Lichtenstein. One recurrence was seen in TEP and Lichtenstein. Post operative pain was least with TEP than the other two groups. Open surgery proved to be more cost effective than TEP. TEP in CONCLUSION: comparison with Stoppas and Lichtenstein is safer with lesser complications and earlier recovery, but less cost effective than open surgery. In developing countries, where cost effectiveness plays a crucial role in deciding the surgery, Stoppas is safe with minimal complications and rapid recovery. This study also demonstrates the effect of surgeon's experience on clinical outcome, with learning curve being shorter in open vs TEP repair
