Objectives: The deep submucosal migration of ingested foreign bodies into the pharyngolaryngeal mucosa is a sporadic event, and its management can be very challenging. In the case of the failure of endoscopic retrieval, open surgical techniques are usually required, and intraoperative ultrasonography can become a useful adjunct for identifying their precise localization. Methods: An 84-year-old woman presented with new-onset dysphagia and odynophagia after the accidental ingestion of a fragment of a toothpick a few hours before in the absence of hoarseness or respiratory distress. Ultrasonography and an unenhanced CT scan of the neck revealed a 3 cm linear foreign body embedded into the neck between the left pyriform sinus and the esophageal wall. Results: We report the removal of a fragment of a wooden toothpick deeply lodged between the left pyriform sinus and the esophageal wall, which was managed via an open transcervical approach with the aid of intraoperative ultrasound guidance. Conclusions: We suggest that both preoperative and intraoperative ultrasonography should represent the first-line imaging technique for deeply embedded neck foreign bodies.

The main advantage of Oblique Lumbar Interbody Fusion (OLIF) is its ability to provide safe access to the lumbar spine while being a robust interbody fusion technique through a minimally invasive approach. This study reviews the postoperative complications of OLIF, offering a comprehensive understanding of its advantages and disadvantages. A total of 27 studies with 1275 patients were shortlisted based on our selection criteria. Complications were categorized into intra-operative, immediate post-operative, and delayed post-operative and were interpreted based on surgical procedure into stand-alone OLIF, OLIF with posterior stabilisation, and unspecified. Major complications exhibited a pooled prevalence of just 1.7%, whereas the overall pooled prevalence of complications was 24.7%. Among the subgroups, the stand-alone subgroup had the lowest prevalence of complications (14.6%) compared to the unspecified subgroup (29.6%) and the OLIF L2-5 with posterior stabilisation subgroup (25.8%). Similarly, for major complications, the stand-alone subgroup had the lowest prevalence (1.4%), while the OLIF L2-5 with posterior stabilisation subgroup (1.8%) and the unspecified OLIF L2-5 subgroup (1.6%) had higher rates. However, the differences were not statistically significant. In conclusion, the rate of major complications after OLIF is minimal, making it a safe procedure with significant benefits outweighing the risks. The advantages of OLIF L2-5 with posterior stabilisation over stand-alone OLIF L2-5 is a subject of discussion.

Introduction: Hemivertebrae are a common defect of vertebral formation, potentially resulting in debilitating congenital scoliosis and necessitating highly traumatic surgery. Virtual surgical planning (VSP) and 3D-printed patient-specific implants (PSIs) have increasingly been applied to complex spinal surgery, and offer a range of potential benefits. Research Question: We report the use of 3D-printed PSIs and VSP as part of a two-level anterior lumbar interbody fusion (ALIF) for the management of lateral hemivertebra and congenital scoliosis. Material and Methods: A 53-year-old male with chronic low-back pain, due to L4 hemivertebra and mild congenital scoliosis, presented with new-onset leg pain. CT revealed L4/5 and L5/S1 degeneration and foraminal stenosis. Given the complex anatomy and extensive multi-level osteophytosis, 3D-printed PSIs were designed, manufactured, and implanted as part of a two-level ALIF. Results: Excellent implant fit was achieved intraoperatively, confirmed via postoperative imaging. VSP assisted with navigating challenging bony and vascular anatomy. Three-month postoperative imaging demonstrated construct stability, early signs of bony fusion, with implant placement, spinal curvature, and disc height corrections closely matching the VSP. Clinically, the patient’s pain and functional impairment had effectively resolved by nine-month follow up, as demonstrated through subjective and objective measures. Discussion and Conclusions: Virtual surgical planning and 3D-printed PSIs can be useful surgical aids in the management of the often-complex cases involving hemivertebrae and congenital scoliosis. This case of congenital pathology adds to the growing reports of PSI application to a variety of complex spinal pathologies, with analyses showing a close match of the postoperative construct to the preoperative VSP.

The main concern in anterior exposure of the lumbosacral spine is the risk of vascular injury during mobilization and retraction of the blood vessels. Preoperative planning is considered essential to reducing the incidence of vascular injury, although no consensus has been reached on the preferred methodology for such planning. This is a retrospective study, including all patients operated on by a single surgeon, who received anterior lumbar-spine surgery in the supine position as a primary procedure before undergoing an anterior lumbar interbody fusion (ALIF) or an artificial disc replacement (ADR). The aim of this study was to list the intraoperative complications observed. We included 156 patients (87 women; mean age, 48 years) who met the inclusion criteria. The overall complication rate was 6.4% (10/156). The most frequent complications were an incidental peritoneal opening (seven patients, 4.4%); two left–iliac-vein injuries (1.28%) that were sutured; and one dural tear during a decompression maneuver of the canal. No neurological, arterial, or ureteral injury or retrograde ejaculation was reported. The use of a sound protocol that includes planning, assessment of approach difficulty, and step-by-step surgical technique can reduce the rate of vascular injury in anterior lumbosacral-spine surgery.

Backgrounds: Liver surgery has developed progressively during the last 10 years, especially in minimally invasive approaches. Robotic surgery seemed to overcome laparoscopic limitations with 3D visualization, the increased degrees of freedom given with Endowrist instruments, tremor filtering, better dexterity, and improved ergonomics for the surgeon. Methods: This work was a retrospective analysis of our first 100 robotic hepatectomies from March 2020 to July 2022. Patient demographics characteristics and intra- and postoperative outcomes were analyzed. Results: A total of 59 males and 41 females, with a median age of 68 years, underwent a robotic liver resection. The indications for robotic liver resections were malignant lesions in 86% of patients. Anatomical resection (AR) was undertaken in 27% of cases and non-anatomical resection (NAR) in 63% of cases. None of the patients were converted to the ‘open’ approach. Postoperative complications were as follows: 1% of biliary leakage, 5% of ascites, 6% of pulmonary infections, and 3% of other sites’ infections. CONCLUSIONS Our results showed the satisfactory experience of a tertiary HPB center with its first 100 robotic liver resections. The opportunity to make the robotic approach routinary provided global growth of a surgical team, improving the quality of patient outcomes.

Amniotic Band Syndrome (ABS) is a complex condition characterized by constricting rings and tissue synechiae, resulting in tissue necrosis and congenital anomalies. In newborns and infants with ABS, tissue necrosis can be profound, requiring a tissue defect reconstruction, realized by a Keystone Perforator Island Flap (KF). Primarily used for reconstruction after skin cancer excisions, KF’s applications expanded to defects of various etiologies and disorders throughout the body. Subsequently, additional KF types adapted to the particular tissue defects were developed. The KF’s preparation is relatively simple to perform leading to shorter operative times, and the postoperative monitoring is less laborious. Individualized surgical approaches and timing are essential for addressing the varied manifestations of ABS, with immediate treatment recommended for vascular compression, all-layered tissue necrosis, and nerve compression cases. To our knowledge, there is no published case in which a KF was used for the reconstruction of tissue defects and release of constriction rings in the context of an amniotic band syndrome. Therefore, the purpose of this article is to introduce the established surgical technique of KFs as an innovative surgical approach with satisfying reconstructive results for tissue defects and constriction ring release in ABS.
羊膜带综合征(Amniotic Band Syndrome, ABS)是一种以缩环和组织粘连为特征的复杂疾病，可导致组织坏死和先天性异常。新生儿和婴儿ABS，组织坏死可能是严重的，需要组织缺损重建，通过拱心石穿支岛皮瓣(KF)实现。主要用于皮肤癌切除后的重建，KF的应用扩展到全身各种病因和疾病的缺陷。随后，开发了适应特定组织缺陷的其他KF类型。KF的准备相对简单，可缩短手术时间，术后监测也不那么费力。个体化的手术方式和时机对于解决ABS的各种表现至关重要，对于血管压迫、全层组织坏死和神经压迫的病例，建议立即治疗。据我们所知，在羊膜带综合征的情况下，没有发表过KF用于组织缺损重建和收缩环释放的病例。因此，本文的目的是介绍已建立的KFs手术技术，作为一种创新的手术方法，对ABS组织缺损和收缩环释放具有满意的重建效果。

Anesthetic management for pregnant patients suffering from airway pathology poses unique challenges. The presence of a bilateral vocal cord granuloma adds further complexity to anesthetic management as it can potentially cause a compromised airway and respiratory distress. This case presents a pregnant patient with a bilateral vocal cord granuloma who underwent anesthesia using high-flow nasal cannula (HFNC) oxygenation and oxygen reserve index (ORi) monitoring. A 33-year-old pregnant woman, who underwent intubation six months ago, experienced hoarseness and was ultimately diagnosed with a bilateral granuloma. Due to the significant airway obstruction, neither intubation nor ventilation was feasible, thereby requiring a surgical intervention. Before the surgical removal, the patient’s oxygenation was ensured using HFNC oxygenation. After confirming the sufficient oxygenation of the patient with an ORi of 0.38, the operation commenced, and as it lasted approximately 3 min, the patient was able to tolerate the brief period without additional oxygen supply. Post-surgical excision, mask bagging, and HFNC oxygenation was resumed, driving the ORi to 0.39; then, the operation was resumed. Throughout the procedure, the SpO2 remained above 98. The combination of HFNC and ORi ensured adequate oxygenation and allowed for the early detection of hypoxemia during the procedure. This approach may be a good option for managing granulomas.

Objectives: This study was designed to determine objective surgical indications of correcting caudal end deviation of the nasal septum. Methods: We employed quantitative computed tomographic (CT) analysis and assessed the validity by comparing this with anterior rhinoscopic findings (AR findings). The study population consisted of 300 patients. The archived CT data were transferred to a workstation, and 3D CT volume-rendered images were generated using computer graphics tools. In the plane of the nostril entrance, we calculated ratios of the cross-sectional area of the convex side (narrower side) and the concave side (wider side), which is abbreviated as the N/W ratio. We also examined the presence of laterality between the right and the left cross-sectional area of the nasal valve based on the AR findings. Surgical procedures for whether to expose the caudal end were planned based on the AR findings and the N/W ratio. Results: A significant correlation was found between the AR findings and the N/W ratio. After surgery, the average N/W ratio improved from 0.53 ± 0.15 to 0.81 ± 0.15, and the average values of VAS scaling for nasal obstruction improved from 8.1 ± 0.2 to 1.0 ± 0.1. Conclusions: The quantitative CT analysis proposed in the study is a useful modality to objectively determine the surgical indications of managing the caudal end of the nasal septum.

Purpose: Although open reduction and internal fixation (ORIF) by plating are the treatment of choice for diaphyseal fractures of the forearm, delayed union and non-union remain as existing complications. This study aimed to analyze predictive factors for the union time in diaphyseal fractures of the forearm. Methods: A retrospective study was conducted on all adult patients with diaphyseal forearm fractures who underwent surgical treatment with plate fixation between 2007 and 2016 at a tertiary care referral center. The patients were divided into two groups based on their union times: ≤3 months or >3 months. They were then compared for demographics, fracture pattern and characteristics, associated injuries, type of fixation, and quality of postoperative reduction. Results: Eighty-six diaphyseal forearm bone fractures (radius, ulna, or both) were observed in 55 adults. Out of these fractures, 55 (65.1%) achieved union within ≤3 months, 26 (30.3%) took more than 3 months to achieve union, and 4 (4.6%) resulted in nonunion. The use of a locking plate in open reduction and internal fixation of diaphyseal forearm fractures significantly increased the likelihood of union within ≤3 months (p = 0.043). The parameter of gap width at the fracture site, as observed on postoperative X-rays, showed a qualitative and quantitative correlation with union time (p = 0.028). Conclusion: The use of a locking plate, combined with reducing the gap width at the fracture site after reduction during open reduction and internal fixation (ORIF) of diaphyseal forearm fractures, is significantly correlated with an increased likelihood of achieving bone union within 3 months.

The patients were divided into two groups based on their union times: ≤3 months or >3 months. They were then compared for demographics, fracture pattern and characteristics, associated injuries, type of fixation, and quality of postoperative reduction. Results: Eighty-six diaphyseal forearm bone fractures (radius, ulna, or both) were observed in 55 adults. Out of these fractures, 55 (65.1%) achieved union within ≤3 months, 26 (30.3%) took more than 3 months to achieve union, and 4 (4.6%) resulted in nonunion. The use of a locking plate in open reduction and internal fixation of diaphyseal forearm fractures significantly increased the likelihood of union within ≤3 months (p = 0.043). The parameter of gap width at the fracture site, as observed on postoperative X-rays, showed a qualitative and quantitative correlation with union time (p = 0.028). Conclusion: The use of a locking plate, combined with reducing the gap width at the fracture site after reduction during open reduction and internal fixation (ORIF) of diaphyseal forearm fractures, is significantly correlated with an increased likelihood of achieving bone union within 3 months.","PeriodicalId":40379,"journal":{"name":"Surgical Techniques Development","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42848225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since its inception in the early 1970s, bariatric surgery has experienced remarkable advancements, leading to improved patient outcomes. However, amidst these developments, the once-popular ileojejunal bypass procedure has faded into obscurity, along with its associated risks and complications. In this particular case, we present the medical history of a 68-year-old male who endured prolonged hospitalization due to a myriad of health issues, including malnutrition, kidney stones, chronic kidney disease, and persistent diarrhea following an ileojejunal bypass performed back in 1973. Troublingly, his symptoms were erroneously attributed to other causes for an extended period, overlooking the potential long-term effects of his prior surgery. This case emphasizes the importance of recognizing and monitoring the lasting impacts of historical surgical interventions, as well as the need for heightened vigilance in postoperative care.
