Targeted Muscle Reinnervation: Factors Predisposing to Successful Pain Score Reduction.

BACKGROUND: Targeted muscle reinnervation (TMR) has demonstrated efficacy in reducing neuroma and chronic pain. In this article, we investigated postoperative outcomes in our patient cohort, with a focus on the role of nonmodifiable factors such as patient age and gender. METHODS: Patients who had extremity TMR from April 2018 to October 2022 were reviewed. Outcomes of interest included patient age, gender, cause and type of amputation, delayed versus immediate TMR, as well as postoperative improvement in pain as assessed by numerical rating score (NRS). RESULTS: A total of 40 patients underwent TMR on 47 limbs. Mean age was 46.2 ± 17.0 years. Delayed TMR (27, 57.4%) was most commonly performed, followed by immediate and delayed-immediate at 11 (23.4%) and 9 (19.1%), respectively. Amputation level was most commonly above-knee in 20 (42.6%) patients, followed by below-knee (12, 25.5%), transhumeral (8, 17.0%), transradial (6, 12.8%), and shoulder (1, 2.1%). The median time interval between amputation and TMR was 12 months. The median preoperative NRS assessing residual limb pain (RLP) for patients who underwent delayed TMR was 10. The median postoperative NRS assessing RLP for all patients was 0 (interquartile range25-75: 0-5) and significantly improved compared with preoperative NRS (P < 0.001). At the last follow-up for limbs that had delayed and delayed-immediate TMR (n = 36), 33 (91.7%) limbs had more than 50% resolution of RLP. There was a significant difference in median postoperative NRS by gender (4 in men and 0 in women) (P < 0.05). Postoperative median NRS also favored younger patients (0, <50 years compared with 4.5, >50 years) (P < 0.05). Multiple linear regression analysis showed that, of different variables analyzed, only male gender and older age were predictive of poorer postoperative outcomes. CONCLUSION: TMR showed high efficacy in our cohort, with improved short-term outcomes in women and younger patients.

Factors Affecting Outcomes After Free Functional Gracilis Muscle Transfer for Elbow Flexion in Brachial Plexus Injury: A Systematic Review and Meta-Analysis.

PURPOSE: Free functional gracilis transfer (FFGT) is a useful option for reconstruction of elbow flexion following brachial plexus injury presenting late or with poor outcomes from previous nerve surgery. In this systematic review and meta-analysis, we aimed to investigate variables associated with superior outcomes. The efficacy of single versus double FFGT, where the first FFGT is performed to restore elbow flexion, and the choice of donor nerve for neurotization were evaluated. METHODS: A meta-analysis was conducted, including studies that provided postoperative Medical Research Council (MRC) grade for elbow flexion, Disabilities of the Arm, Shoulder, and Hand and visual analog scale scores, quantitative elbow flexion strength, and range of motion. A random effects meta-regression analysis was performed to identify factors associated with improved outcomes. RESULTS: Thirty-seven studies, with 1,607 patients, were analyzed. Single FFGT was reported in 34 studies (n = 1,398), and double FFGT was reported in 10 studies (n = 209). The mean follow-up duration was 37.3 ± 21.1 months. Following single FFGT, 75.4% and 48.9% achieved MRC grades ≥3 and ≥4, respectively. Following double FFGT, 100% achieved an MRC grade ≥3 and 62.7% ≥4. The likelihood of achieving M3 and M4 was significantly greater for double FFGT. Overall, FFGT innervated by the spinal accessory nerve had significantly better recovery of MRC grade ≥3. When comparing only single and double FFGT innervated by spinal accessory nerve, there was no significant difference in recovery of elbow flexion. The meta-regression analysis showed a significant negative correlation between the patient's age and the probability of achieving an MRC grade of ≥3 and 4. CONCLUSIONS: In the overall analysis encompassing all innervating nerves, double FFGT was superior to single FFGT. Subgroup analysis of single and double FFGT innervated by the spinal accessory nerve showed no significant difference. Increasing age was a significant risk factor for poorer outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Combined Distal Interphalangeal Joint Arthrodesis With Proximal Interphalangeal Joint Arthroplasty or Arthrodesis: Technical Considerations.

Combined distal interphalangeal joint (DIP) arthrodesis with proximal interphalangeal joint (PIP) arthroplasty or arthrodesis presents unique challenges. Although less common than isolated surgery for the DIP and PIP joints, with an aging population, combined DIP and PIP procedures are an increasingly encountered occurrence. Anatomical and morphological studies have provided length and width measurement standards for the middle and distal phalanges, allowing for planning to assess the compatibility of strategies. Besides reviewing anatomical studies to provide length and width guidelines for hardware placement, we will also discuss optimal hardware combinations for combined surgical intervention in the DIP and PIP joints. Conflict may exist between hardware used for the DIP arthrodesis and implants used for the PIP arthroplasty. As an example, if K-wires are used for DIP arthrodesis, any intervention in the PIP joint will be compatible. However, if headless screws are used for DIP arthrodesis, these should ideally not reach proximal to the midpoint of the middle phalanx. Other techniques, such as single or multiple oblique screws, and tension bands are compatible with PIP arthroplasty. Hence, options for management of the PIP joint are dependent on the technique used for DIP arthrodesis.

Evaluation of Different Surgical Techniques for Revision Cubital Tunnel Release: A Meta-Analysis of Patient-Reported Symptoms.

PURPOSE: Controversy exists regarding the best option for revision surgery in refractory cubital tunnel syndrome (CuTS). The purpose of this systematic review was to evaluate the effectiveness of revision surgery and determine the optimal surgical approach for patients requiring revision surgery for CuTS. METHODS: A literature search was conducted. Characteristics of the included studies were summarized descriptively. The risk ratio between patient-reported preoperative and postoperative outcomes relating to pain, motor, and sensory deficits was calculated. A meta-regression analysis was performed to evaluate the postoperative symptom improvements based on the type of secondary surgery. Random-effects meta-analysis and descriptive statistics were used when appropriate. RESULTS: A total of 471 patients were evaluated in 20 studies. In total, 254 (53.9%) male and 217 (46.1%) female patients, with an average age of 49.2 ± 14.1 years, were included in this study. Pain was the most common symptom (n = 346, 81.6%), followed by sensory and motor dysfunction in 342 (80.6%) and 223 (52.6%) patients, respectively. Meta-analysis comparing preoperative and postoperative symptoms between patients who had submuscular transposition (SMT), subcutaneous transposition (SCT), and neurolysis showed that a significant subgroup difference exists between the types of revision surgery in sensory and motor improvements. Meta-regression showed that SMT was associated with better outcomes compared with SCT in motor and sensory improvements. CONCLUSIONS: Revision surgery for CuTS can be useful for addressing recurrent and persistent symptoms. Compared with neurolysis and SCT, SMT seems to be the superior option for revision surgery, demonstrating substantial improvement in all symptom domains. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Evaluation of the features of cystic echinococcosis with concurrent super-infection: a retrospective study in Southern Iran.

OBJECTIVE: Superinfection of cystic echinococcosis (CE) is a life-threatening complication with significant morbidities, which can be prevented with early diagnosis and treatment. This study aims to examine the clinical characteristics, diagnostic methods, and treatment options for superinfected CE, as there is currently limited information available on the differences between superinfected and non-infected CE in terms of clinical features, serological and radiologic findings. METHODS: This cross-sectional study was conducted on hospital records of patients who were diagnosed with hydatid cysts in a 15-year period (2004 to 2018) in two main university-affiliated referral centers in Fars province, southern Iran. Patients' information regarding the demographical and clinical features related to CE, age, sex, previous history of CE or recurrence, size and location of CE, and length of hospital stay were collected. Moreover, the characteristics of concurrent infections with hydatid cysts were recorded. RESULTS: A total of 586 surgeries due to CE were performed on 501 patients, of which 67 (11.43%) had reoperations due to the recurrence of the disease. A total of 30 (5.99%) incidences of superinfection were observed. There were no statistically significant differences in terms of laboratory and imaging findings between CE patients with concurrent infections and other CE patients (p-value > 0.05). Among the patients with super-infection, four had fungal infections of the lungs. Aspergillus fumigatus was the causative pathogen in all four patients that were diagnosed with fungal superinfection. All patients underwent surgical excision with favorable long-term outcomes. CONCLUSION: Our study revealed a 5.99% incident rate of CE superinfection. Regarding the concurrent fungal infections in hydatid cysts, the patient's symptoms and laboratory and imaging findings are inconclusive and histopathological evaluation seems to be the most reliable option. Surgical resection is the gold-standard treatment option with favorable outcomes and potentially can be curative.

Esophageal perforation etiology, outcome, and the role of surgical management - an 18-year experience of surgical cases in a referral center.

INTRODUCTION: Esophageal perforation is a surgical emergency with a high rate of morbidity and mortality. Its poor prognosis is mainly associated with previous patient-specific comorbidities and a lack of timely diagnosis and treatment. The objective of this study was to investigate the etiological factors and different surgical methods of treatment with consideration of mortality rate and comorbidities. METHOD: The present cross-sectional study was conducted on patients who underwent surgical intervention due to esophageal injury from 2002 to 2019 (18 years). Demographic and clinical characteristics along with performed surgical interventions were evaluated accordingly. RESULTS: In this study, 69 patients with a mean age of 38.8 years were evaluated, of which 45 (65.2%) cases were men. In terms of location of the perforation, the thoracic portion of the esophagus followed by the cervical and abdominal esophagus were more frequently injured with a rate of 32 (46.4%), 30 (43.5%), and 19 (27.5%) cases, respectively. Accordingly, foreign body ingestion followed by penetrating injuries were the most common causative agents leading to esophageal perforation. CONCLUSION: Obtaining the desired results from the treatment of this condition depends on factors such as patients' previous comorbidities, cause of the rupture, the location of the esophageal damage, and delay in the start of treatment. Since there is no single gold standard treatment strategy, each patient should be individually evaluated.

Evolution and Application of Ultrasound for Flap Planning in Upper Extremity Reconstruction.

Accurate preoperative localization of dominant perforators provides crucial information about their location and diameter, leading to reduced surgical time, improved flap viability, and decreased complications. Ultrasound has increased in popularity in recent years, with the advantages of providing reproducible, accurate, cost-effective, and real-time information while reducing radiation exposure. Precise preoperative mapping of perforators allows for rapid and safe elevation of suprafascial, thin, and superthin flaps. This review focuses on the role of ultrasound as a tool for preoperative flap planning in the upper extremities.

The role of surgery in the management of radiation-induced brachial plexopathy: a systematic review.

This systematic literature review of the clinical characteristics of radiation-induced brachial plexopathy and outcomes after intervention includes 30 trials with 611 patients. The mean radiation dose to the brachial plexus was 56 Gy, and the mean duration of radiation was 4 weeks. The mean time from radiation to the onset of symptoms was 35 months. The most commonly reported symptom was sensory loss (n = 323, 62%), followed by motor deficits (n = 294, 56%) and neuropathic pain (n = 284, 54%). In total, 65 (56%) patients had panplexus involvement and 51 (44%) patients had partial plexus involvement. The most common surgical procedure was neurolysis with flap coverage (n = 108, 6%), followed by neurolysis alone (n = 71, 30%). Of the 237 patients who underwent surgery, 125 (53%) reported an improvement in pain. Motor and sensory deficits were improved in 46 (19%) and 39 (16%) patients, respectively, suggesting that surgery is beneficial in relieving pain, but not as beneficial in restoring motor and sensory function.

Challenges and Advances in the Diagnosis and Management of Neurogenic Thoracic Outlet Syndrome: A Comprehensive Review.

Neurogenic thoracic outlet syndrome (nTOS) is caused by brachial plexus compression in the thoracic outlet. It accounts for 85%-95% of thoracic outlet syndrome (TOS) cases, which may also be caused by compression of the subclavian artery and vein. Compression occurs in the interscalene triangle, costoclavicular space or subpectoralis minor space, with congenital anomalies and repetitive overhead activities as contributing factors. Diagnosis is challenging due to overlapping symptoms with other conditions. Patients commonly report pain, numbness, tingling and weakness in the neck, shoulder and arm, exacerbated by arm elevation. Symptoms related to nTOS may manifest in the distribution of the upper (C5-C6), middle (C7) and lower plexus (C8-T1). Although widely used, provocative tests have varying degrees of sensitivity and specificity and may have high false-positive rates, complicating the diagnosis. Patterns on electrodiagnostic studies provide key diagnostic clues, such as reduced sensory response in the medial antebrachial cutaneous nerve and low compound motor action potential in the median nerve. Imaging techniques like magnetic resonance imaging (MRI), alongside procedures like diagnostic and therapeutic anterior scalene blocks, assist in identifying anatomical abnormalities and predicting surgical outcomes. Management of nTOS involves lifestyle changes, physical therapy, medication and botulinum toxin injections for symptomatic relief. Surgical options may include supraclavicular, transaxillary and infraclavicular approaches, each offering specific benefits based on patient anatomy and surgeon expertise. Minimally invasive techniques, such as video-assisted thoracoscopic surgery (VATS) and robotic surgery, enhance exposure and dexterity, leading to better outcomes. Future research should focus on developing precise diagnostic tools, understanding nTOS pathophysiology, standardising diagnostic criteria and surgical approaches, comparing long-term treatment outcomes and exploring preventive measures to improve patient care and quality of life. Level of Evidence: Level V (Therapeutic).

Factors correlating with positive electrodiagnostic findings for neurogenic thoracic outlet syndrome.

INTRODUCTION: Diagnosis of neurogenic thoracic outlet syndrome (nTOS) remains a challenge. The role of electrodiagnostic studies (EDX) in the workup of nTOS remains controversial. The aim of this study was to report the EDX findings in a cohort of patients who underwent surgery for nTOS and also analyze patient-related and intraoperative factors associated with positive EDX findings supportive of nTOS diagnosis. METHODS: Baseline characteristics of patients, including age, sex, duration of symptoms, type of nTOS, and pattern of brachial plexus involvement, were gathered and analyzed. All patients received a preoperative EDX evaluation and were divided into two groups based on positive or negative EDX results for comparison. RESULTS: A total of 30 consecutive patients were included in this study comprising 11 (36.7%) men and 19 (63.3%) women, with a mean age of 44.6 ± 17.6 years. Twenty-two (73.3%) patients had type 1 nTOS with muscle weakness and atrophy, followed by 7 (23.4%) patients with type 3, and 1 (3.3%) patient with type 2 nTOS. In terms of nTOS pattern, 26 (86.7%) patients had lower plexus pattern of involvement (C8-T1), followed by 17 (56.7%) with upper-middle plexus pattern (C6-C7), and 13 (43.3%) with upper plexus pattern (C5-dorsal scapular nerve (DSN)). When comparing the characteristics of patients with positive and negative EDX findings suggestive of nTOS, only older age and type 1 nTOS (P < 0.05) were significantly associated with positive EDX findings. CONCLUSIONS: Currently, EDX assessment may not be the best modality for diagnosis of nTOS. Interindividual variation in findings reported by different clinicians performing the EDX remains a significant limiting factor. Older patients and those with more severe nTOS (type 1) are more likely to have positive results with EDX.

Thin Profunda Artery Perforator Flap for Hand and Upper Extremity Coverage.

The profunda artery perforator (PAP) flap provides a good option for hand and upper extremity reconstruction. The reliable quality, caliber, and number of perforators in the posteromedial thigh support large flaps with long pedicles. The PAP flap has been widely used for breast reconstruction, although its use in the extremities has been slower to catch on due to the bulk and thickness of the subcutaneous tissue. The authors discuss evolution of thin flaps and our application of the thin and superthin PAP flap for upper extremity reconstruction.

Development of Biomaterials for Addressing Upper Extremity Peripheral Nerve Gaps.

Peripheral nerve injuries within the upper extremities can lead to impaired function and reduced quality of life. Although autografts have traditionally served as the primary therapeutic approach to bridge nerve gaps, these present challenges related to donor site morbidity. This review delves into the realm of biomaterials tailored for addressing nerve gaps. Biomaterials, whether natural or synthetically derived, offer the potential not only to act as scaffolds for nerve regeneration but also to be enhanced with growth factors and agents that promote nerve recovery. The historical progression of these biomaterials as well as their current applications, advantages, inherent challenges, and future impact in the arena of regenerative medicine are discussed. By providing a comprehensive overview, we aim to shed light on the transformative potential of biomaterials in peripheral nerve repair and the path toward refining their efficacy in clinical settings.

The Safety and Efficacy of Dorsal Root Entry Zone Lesioning for Pain Management in Patients With Brachial Plexus Avulsion: A Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Persistent neuropathic pain after brachial plexus avulsion (BPA) is common and generally nonresponsive to medical management. Dorsal root entry zone (DREZ) lesioning is the last resort for pain management in patients with BPA. This study aims to investigate and compare the outcomes and complications of DREZ procedures. METHODS: A systematic literature search was conducted to identify all related studies. Comparisons were based on the number of patients with preoperative pain vs postoperative pain, with the effect size calculated using the risk ratio. Mean visual analog scale (VAS) scores were extracted and analyzed between interventions. A meta-regression analysis was performed to identify risk factors for final outcomes. The rates of complications were also assessed and analyzed between interventions. RESULTS: A total of 30 studies with 917 patients (90.0% male and 10.0% female, mean age: 42.9 ± 16.6) were included in this systematic review. Of the 917 patients who underwent surgery, 655 (71.4%) patients had significant pain reduction at the last follow-up ( P < .05). The weighted mean preoperative VAS score was 8.3 ± 1.3, compared with postoperative VAS scores (1.9 ± 2.2); a significant improvement was observed ( P < .05). The subgroup analysis showed that microsurgical DREZotomy (MDT) is associated with better outcomes in terms of VAS score improvements compared with radiofrequency (RF)-assisted DREZ lesioning ( P < .05). Meta-analysis showed that the relative risk of motor deficits was significantly lower in the MDT group, compared with the RF-assisted group ( P < .05). Meta-regression showed that older age is correlated with an elevated risk of postoperative motor deficits compared with the incidence of sensory loss. CONCLUSION: DREZ lesioning is effective for intractable pain alleviation after BPA. Compared with RF-assisted DREZ lesioning, MDT is associated with better VAS score improvements and a lower rate of postoperative motor weakness.

Contributors to post-operative venous thromboembolism risk after breast cancer surgery: A systematic review and meta-analysis.

INTRODUCTION: Venous thromboembolism (VTE) events are a preventable complication for patients undergoing surgery for breast cancer. However, there is a lack of consistency in the existing literature regarding the potential risk factors affecting these individuals. METHODS: This study aimed to investigate the potential risk factors associated with an increased risk of VTE following surgery for breast cancer. Data on patient characteristics such as age, body mass index (BMI), existing comorbidities, smoking history, surgical interventions, duration of hospitalization, and post-operative complications were recorded and analyzed. RESULTS: Thirty-one studies investigating the incidence of VTE following surgical interventions for breast cancer were included. This study included 22,155 female patients with a mean age of 50.8 ± 2.9 years. The weighted mean length of surgery and hospital stay were 382.1 ± 170.0 min and 4.5 ± 2.7 days, respectively. The patients were followed-up for a weighted mean duration of 13.8 ± 21.2 months. The total incidence of VTE events was 2.2% (n = 489). Meta-analysis showed that patients with post-operative VTE had a significantly higher mean age and BMI, as well as longer mean length of surgery (P < 0.05). Comparing the techniques of autologous breast reconstruction showed that the risk of post-operative VTE is significantly higher with deep inferior epigastric perforator (DIEP) flaps, compared with the transverse rectus abdominus myocutaneous and latissimus dorsi myocutaneous flaps (P < 0.05). Compared with delayed reconstruction, immediate reconstruction was associated with a significantly higher incidence of VTE (P < 0.05). Smoking history, length of hospital stay, and Caprini score did not correlate with increased incidence of post-operative VTE. CONCLUSION: The incidence rate of VTE events in patients receiving surgical treatment for breast cancer is 2.2%. Risk factors for developing post-operative VTE in this patient population were found to be older age, increased BMI, extended length of surgical procedures, and DIEP flap reconstruction.

Single versus double fascicular transfer for brachial plexus injuries: a systematic review and meta-analysis with meta-regression.

The primary objective of this review was to assess whether double fascicular transfer has superior outcomes compared with single fascicular transfer for reanimation of elbow flexion. In total, 58 studies including 1388 patients (mean age 29 years [SD 8]) were included. Subgroup analysis comparing the severity of brachial plexus injury (C5-C6, C5-C7, C5-C8) showed no significant difference in the recovery of MRC grade 3 and 4. The aggregated mean Disabilities of Arm, Shoulder and Hand score was 38 for the single fascicular transfer group and 27 for the double fascicular transfer group. Meta-regression controlling for level of injury showed that double fascicular transfer and C5-C6 injury were significant predictors of achieving MRC grade 3, while double fascicular transfer and shorter duration of surgical delay were significant predictors of achieving MRC grade 4. When controlling for the level of injury, double fascicular transfer is associated with a greater likelihood of achieving MRC grade 3 and 4 compared to single fascicular transfer. Overall donor site morbidity was not significantly different between single fascicular transfer and double fascicular transfer.

Risk of hepatitis B virus reactivation in cancer patients undergoing treatment with tyrosine kinase-inhibitors.

This editorial commented on an article in the World Journal of Gastroenterology titled "Risks of Reactivation of Hepatitis B Virus in Oncological Patients Using Tyrosine Kinase-Inhibitors: Case Report and Literature Analysis" by Colapietro et al. In this editorial, we focused on providing a more comprehensive exploration of hepatitis B virus reactivation (HBVr) associated with the usage of tyrosine kinase inhibitors (TKIs). It includes insights into the mechanisms underlying HBV reactivation, the temporal relationship between TKIs and HBV reactivation, and preventive measures. The aim is to understand the need for nucleos(t)ide analogs (NAT) and serial blood tests for early recognition of reactivation and acute liver injury, along with management strategies. TKIs are considered to be an intermediate (1%-10%) of HBVr. Current guidelines stipulate that patients receiving therapy with high or moderate risks of reactivation or recent cancer diagnosis must have at least tested hepatitis B surface antigen, anti-hepatitis B core antigen (HBc), and anti-hepatitis B surface antibody. Anti-HBc screening in highly endemic areas means people with negative tests should be vaccinated against HBV. Nucleoside or nucleotide analogs (NAs) like entecavir (ETV), tenofovir disoproxil fumarate (TDF), and tenofovir alafenamide (TAF) form the basis of HBV reactivation prophylaxis and treatment during immunosuppression. Conversely, lamivudine, telbivudine, and adefovir are generally discouraged due to their reduced antiviral efficacy and higher risk of fostering drug-resistant viral strains. However, these less effective NAs may still be utilized in cases where ETV, TDF, and TAF are not feasible treatment options.

Patient demographics, tumor characteristics, and outcomes following surgical treatment of benign and malignant brachial plexus tumors: a systematic review.

BACKGROUND: Various treatment options have been introduced for the management of primary tumors of the brachial plexus (BP), ranging from conservative therapy to wide local excision with/without postoperative chemoradiotherapy. However, no consensus exists regarding optimal treatment strategies based on collated and published data. OBJECTIVE: The aim of this study was to investigate the clinicopathological characteristics and outcome of patients with primary tumors of the BP who underwent surgical treatment. DATA SOURCES: A systematic search of the four main online databases, including Web of Science (WOS), PubMed, Scopus, and Google Scholar, was conducted. STUDY SELECTION: All related articles addressing the clinical outcome and role of surgical interventions for management of primary tumors of the BP. INTERVENTION: Optimal surgical and radiotherapeutic interventions for benign and malignant lesions based on the pathologic characteristics and location of primary BP tumors. RESULTS: A total of 687 patients (693 tumors) with a mean age of 41.7±8.7 years old were evaluated. In total, 629 (90.8%) tumors were benign, and 64 (9.2%) were malignant, with a mean tumor size of 5.4±3.1 cm. The location of the tumor was reported for 639 patients. For these tumors, 444 (69.5%) originated from the supraclavicular region, and 195 (30.5%) were infraclavicular. The trunks were the most common location for tumor involvement, followed by the roots, cords, and terminal branches. Gross total resection was achieved in 432 patients and subtotal resection (STR) was performed in 109 patients. With neurofibromas, STR still resulted in good outcomes. The outcomes following treatment of malignant peripheral nerve sheath tumors were poor regardless of the type of resection. In general, symptoms related to pain and sensory issues resolved rapidly postoperatively. However, the resolution of motor deficits was often incomplete. Local tumor recurrence occurred in 15 (2.2%), patients and distant metastasis was observed in only eight (1.2%) cases. The overall mortality was 21 (3.1%) patients among the study population. LIMITATIONS: The main limitation was the lack of level I and II evidence. CONCLUSIONS: The ideal management strategy for primary BP tumors is complete surgical resection. However, in some cases, particularly for neurofibromas, STR may be preferable to preserve maximal neurological function. The degree of surgical excision (total or subtotal) mainly depends on the pathological characteristics and primary location of the tumor.

Marinacci Communication With Recovery of the Thumb, Finger, and Wrist Flexion After a High Median Nerve Injury: A Case Report and Review of Literature.

The Marinacci communication (MC) contains fibers from the ulnar to the median nerve in the forearm in a proximal to distal fashion. This rare ulnar-to-median nerve anomalous communication has mainly been reported as an incidental finding. In the case presented here, this anatomical variation led to rapid recovery of the thumb, finger, and wrist flexion following a high above elbow complete median nerve injury. A 17-year-old female was involved in an all-terrain vehicle rollover accident and had her right elbow crushed. She presented with no motor or sensory function in the forearm and hand, with a weak monophasic radial artery signal and no palpable pulse. She underwent surgery and was treated with 12 cm interposition cable sural nerve grafting. Although recovery after a high median nerve injury is often prolonged and incomplete, the MC resulted in the recovery of sensation and motor function through muscles typically innervated by the median nerve, following a complete high median nerve injury. In the presence of anomalous recovery following median nerve injury or unusual electrophysiological findings, an MC should be considered as a cause.

A ciliated hepatic foregut cyst mimicking hydatid cyst treated with laparoscopic surgery; a case-report and review of literature.

INTRODUCTION AND IMPORTANCE: Congenital hepatic foregut cyst (CHFC) is a rare condition that is derived from an abnormal detachment of esophageal buds during foregut embryonic development. Early treatment is generally recommended due to the potential of malignant transformation. In this study, we are reporting our experience with laparoscopic resection of CHFC in a female patient. CASE PRESENTATION: A 41-year-old female farmer presented with a 5-month history of right upper quadrant (RUQ) pain with a palpable mass. Abdominal examination revealed a visible subhepatic large mass with an estimated size of 10 cm, which was horizontally mobile. Abdominopelvic ultrasonography showed a 76 ∗ 87 ∗ 15 cm single subhepatic cyst with internal septations. The patient was scheduled to undergo laparoscopic surgical resection of the cyst with an initial diagnosis of a hepatic hydatid cyst. Histopathologic evaluations showed that the cyst wall was composed of four layers consistent with the diagnosis of CHFC. CLINICAL DISCUSSION: Due to the disease's rarity there have been various recommendations regarding treatment of CHFC in literature including observation with serial imaging, aspiration, and surgical excision. However, surgical excision is considered the most reasonable option given the chance of malignant transfusion, particularly in patients with enlarging cysts with size of more than 4 cm, cyst wall abnormality, abnormal liver function tests, and symptomatic cases. CONCLUSION: Surgical resection is a feasible option for resection of CHFC given that the cyst wall is thick enough to be excised from the hepatic parenchyma and the lesion is situated on the surface of the liver.

Patient-Reported Outcome Measures After Endoscopic Cubital Tunnel Release With At Least 1-Year Postoperative Follow-up.

BACKGROUND: The primary objective of this study was to investigate midterm outcomes following endoscopic cubital tunnel release (ECuTR) with the Seg-Way system using patient-reported outcome measures (PROMs). A secondary aim was to evaluate symptom resolution as assessed through Dellon's stage, McGowan's grade, and Messina's criteria and recurrence following ECuTR. METHODS: Functional outcomes were assessed in 38 patients who underwent 43 surgeries. Details on baseline characteristics as well as preoperative and postoperative symptoms were collected. Patient-reported outcome measures were administered with at least 1-year follow-up in all patients. RESULTS: Mean age of patients was 50.2 ± 16.1 years, with 20 men (52.6%) and 18 women (47.4%). Postoperatively, pain completely resolved in 21 (72.4%), while sensory and motor deficits improved completely in 22 (56.4%) and 11 (64.7%) patients, respectively. Mean time interval between ECuTR and PROMs was 26.3 (13-63) months. Median Michigan Hand Outcomes Questionnaire score was 73.2 (48-91). Median Disabilities of the Arm, Shoulder and Hand (DASH) and Numerical Rating Scale (NRS) scores were 12.9 (7-35) and 2.5 (0-5), respectively. Most of the patients were satisfied postoperatively with a median satisfaction score of 4 (3-5). There was a significant difference in median DASH and NRS scores between patients with and without concomitant proximal nerve disease. CONCLUSION: Endoscopic cubital tunnel release is a safe and effective option for surgical management of primary cubital tunnel syndrome. The presence of other proximal nerve disease is associated with poorer outcomes, less symptom resolution, and higher recurrence rates. One-year postoperative PROMs show equivalence to those reported in other studies following open cubital tunnel release.
