RESUMEN
BACKGROUND: The aim of this research was to analyse the current literature on displaced dental implants in the mandibular body, including local and systemic variables related to their cause, and to identify the most frequent location. METHODS: The study conducted a search of three databases (Pubmed, Scopus, and Web of Science) using specific index terms such as 'dental implant', 'displacement', 'dislocation', 'displaced', and 'mandible'. The analysis focused on the direction of displacement and the characteristics of the bone tissue (bone quality, density, and quantity) in cases where dental implants were displaced. RESULTS: A total of 371 articles were obtained. Thirteen of these articles were selected and read in full. To define bone quality, the Lekholm and Zarb classification, modified by Rosas et al., was used. The type II-B bone, which is characterized by thick cortical bone surrounding cancellous bone with extremely wide medullary spaces, presented the largest number of complications. Twenty-two cases were found in which the displacement direction was horizontal. Of these, four were displaced vestibularly, fourteen lingually, and four remained in the center. Additionally, 24 cases presented vertical displacement, with 12 displaced towards the inferior border of the mandible, 9 towards the middle or adjacent to the inferior dental nerve canal, and 3 above the inferior dental nerve canal. CONCLUSION: The accidental displacement of implants within the mandibular body is associated with various risk factors, including the characteristics of the bony trabeculum and the size of the medullary spaces. It is reasonable to suggest that only an adequate pre-surgical diagnostic evaluation, with the help of high-resolution tomographic images that allow a previous evaluation of these structures, will help to have better control over the other factors, thus minimizing the risk of displacement.

OBJECTIVES: Proximal migration is one of the complications after pancreatic duct stenting. This study aimed to determine the incidence of proximal migration and to analyze the rescue methods. MATERIALS AND METHODS: A search was performed in MEDLINE/Embase database. The literatures included were reviewed and analyzed. Retrieval tools were classified into the following 3 classes: class A works by indirectly contacting the outer surface of the stent. Class B works by directly contacting the outer surface. Class C works by directly contacting the inner surface. RESULTS: 416 literatures were retrieved from 1983 to 2021. 15 literatures were included. The incidence of proximal migration of pancreatic stents was 4.7% (106/2246). The success rate of endotherapy was 86.6% (214/247), and the surgical conversion rate of it was 9.3%. Among the 214 cases in which the displaced stents were successfully removed under endoscopy, 49 cases (22.9%) used class A methods, 154 cases (72.0%) used class B methods, and 11 cases (5.1%) used class C methods. The overall rate of postoperative complication was 12.1%, including postprocedure pancreatitis (9.1%, 18/247), followed by bleeding (1.5%), perforation (1.0%), and biliary infection (0.5%). CONCLUSIONS: Endoscopy is an effective method for the treatment of proximal displacement of pancreatic stents with acceptable complication rate.

Tension band wiring (TBW) is one of the most commonly used fixation techniques to fix olecranon osteotomies. Hardware prominence has been the most commonly reported complication of TBW. However, distal migration of Kirschner (K)-wire after TBW fixation for olecranon osteotomy has not been reported. In this case report, we presented distal migration of K-wire detected nine months after initial surgery in a 46-year-old male patient. The patient was operated on for an intraarticular distal humerus fracture using an olecranon osteotomy. The osteotomy was fixed with TBW fixation. The patient missed routine follow-ups and presented to the outpatient clinic with a complaint of skin irritation at the elbow nine months after the surgery. On radiological examination, distal migration of one K-wire was detected. The K-wire was surgically removed without any complication. Physicians should be aware of possible complications of TBW and remove fixation after fracture union to avoid unexpected complications.

The use of left atrial appendage occlusion (LAAO) devices have gained prominence as an alternative to long-term anticoagulation therapy in patients with atrial fibrillation at risk of stroke and high risk of bleeding. While these devices have shown efficacy in reducing stroke risk, there have been reported cases of embolization of the Watchman device. There are very few cases of successful percutaneous retrieval of embolized Watchman devices from the left ventricle (LV), as many of these cases require open heart surgery for safe removal. We are presenting a case of an 80-year-old male whose Watchman device embolized to the LV and was entrapped on the LV papillary muscle that was then successfully retrieved via percutaneous methods, which shows the percutaneous options remain a viable strategy to retrieve LAAO devices from the LV.

BACKGROUND: The influence of tibial slope on tibial component migration following total knee arthroplasty has not been widely studied, although excessive posterior slope has been implicated in some failures. As implant micromotion measured with radiostereometric analysis can indicate successful fixation, the purpose of this study was to determine the associations between tibial slope, tibial component migration, and inducible displacement. METHODS: Radiostereometric analyses at 6 visits over 2 years quantified implant migration for 200 cemented total knee arthroplasties. Longitudinal data analysis examined the influence of postoperative tibial slope on implant migration (overall maximum total point motion (MTPM) migration and anterior-posterior tilt migration), accounting for age, sex, and body mass index. The correlations of tibial slope with 1-year migration, continuous migration, and inducible displacements were also examined. Additionally, the amount of change in slope was compared to migration. RESULTS: The mean posterior tibial slope was 8.0° (standard deviation [SD] 3.8°) preoperatively and 3.8° (SD 3.1°) postoperatively, with a mean reduction in slope of 4.2° (SD 4.7°). Postoperative tibial slope (range 14.0° posterior slope to 3.4° anterior slope) was not associated with longitudinal overall migration (P = .671) or anterior-posterior tilt migration (P = .704). There was no association between postoperative tibial slope and migration at 1 year postoperatively (P = .441 for MTPM migration, P = .570 for tilt migration), change in migration from 1 to 2 years (P = .951), or inducible displacement (P = .970 MTPM, P = .730 tilt). The amount of change in tibial slope was also not associated with migration or inducible displacement. CONCLUSIONS: Residual and change in postoperative tibial slope were not associated with implant migration into tilt or overall migration, or inducible displacement for a single implant design. These findings support positioning tibial implants in a range of slopes, which may support patient-specific approaches to implant alignment.

INTRODUCTION: Pancreatic duct stents (PDS) are widely used for the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. However, there is a paucity of data regarding the adverse events associated with PDS placement. This study aims to investigate the reported adverse events and device failures related to PDS, utilizing the Manufacturer and User Facility Device Experience (MAUDE) database maintained by the U.S. Food and Drug Administration (FDA). METHODS: Post-marketing surveillance data from January 2013 to December 8, 2023, were extracted from the FDA's MAUDE database to analyze the reports pertaining to the use of commonly used PDS. The primary outcomes of interest were device issues and patient-related adverse events. Statistical analysis was performed using Microsoft Excel 2010, with the calculation of pooled numbers and percentages for each device and patient adverse event. RESULTS: A total of 579 device issues and 194 patient-related adverse events were identified. Device issues were primarily attributed to stent deformation (n = 72; 12.4%), followed by migration of the device into the pancreatic duct or expulsion out of the duct (n = 60; 10.4%), and stent fracture/breakage (n = 55; 9.4%). Among the patient-reported adverse events, inflammation was the most common (n = 26; 13.4%), followed by reports of stents becoming embedded in tissue (n = 21; 10.8%) and stent occlusion/obstruction (n = 16; 8.2%). The most prevalent device failures associated with Advanix stents were material deformation, with perforation (n = 3, 30%) being the most frequently reported adverse event. Concerning Geenen stents, migration or expulsion of the device (n = 34, 16.9%) constituted the most common device-related adverse events, while inflammation (n = 20, 16.7%) was the most frequently reported patient-related issue. For Zimmon stents, migration or expulsion of the device (n = 22, 8.8%) were the most frequently reported device-related problems, whereas perforation (n = 7, 10.9%) and bleeding (n = 7, 10.9%) were the most frequent patient-related adverse events. CONCLUSION: Our findings highlight important device and patient adverse events that endoscopists and referring providers should be aware of before considering pancreatic stent placement.

BACKGROUND: Foreign bodies within the pleura and pancreas are infrequent, and the approaches to their treatment still a subject of debate. There is limited knowledge particularly regarding glass foreign bodies. METHODS: We present a case involving large glass splinters in the pleura and pancreas, with an unknown entry point. In addition, a systematic review was conducted to explore entry hypotheses and management options. RESULTS: In addition to our case, our review uncovered eight incidents of intrapleural glass, and another eight cases of glass in other intrathoracic areas. The fragments entered the body through impalement (81%), migrated through the diaphragm after impalement (6%), or caused transesophageal perforation (19%) following ingestion. Eight instances of glass inside the abdominal cavity were documented, with seven resulting from impalement injuries and one from transintestinal migration. There were no recorded instances of glass being discovered within the pancreas. Among the 41 nonglass intrapancreatic foreign bodies found, sewing needles (34%) and fish bones (46%) were the most common; following ingestion, they had migrated through either a transgastric or transduodenal perforation. In all these cases, how the foreign bodies were introduced was often poorly recalled by the patient. Many nonglass foreign bodies tend to become encapsulated by fibrous tissue, rendering them inert, though this is less common with glass. Glass has been reported to migrate through various tissues and cavities, sometimes with a significant delay spanning even decades. There are cases of intrapleural migration of glass causing hemothorax, pneumothorax, and heart and major blood vessels injury. For intrapleural glass fragment management, thoracoscopy proved to be effective in 5 reported cases, in addition to our patient. Most intrapancreatic nonglass foreign bodies tend to trigger pancreatitis and abscess formation, necessitating management ranging from laparoscopic procedures to subtotal pancreatectomy. There have been only four documented cases of intrapancreatic needles that remained asymptomatic with conservative management. There is no direct guidance from the existing literature regarding management of intrapancreatic glass foreign bodies. Consequently, our patient is under observation with regular follow-ups and has remained asymptomatic for the past 2 years. CONCLUSIONS: Glass foreign bodies in the pleura are rare, and our report of an intrapancreatic glass fragment is the first of its kind. Impalement is the most likely method of introduction. As glass has significant migration and an ensuing complication potential, preventive removal of intrapleural loose glass should be considered. However, intrapancreatic glass fragment management remains uncertain.

BACKGROUND: Continuous peripheral nerve blocks are commonly used for pain management. However, the incidence of catheter dislodgement or migration is unclear, and may be underestimated and underreported. Our objective was to assess suprascapular catheter tip positioning before and after routine simulated shoulder physiotherapy manipulation in an anatomical cadaver model. METHOD: Eight ultrasound-guided continuous suprascapular nerve block catheters were placed in cryopreserved fresh cadavers. Computed tomography (CT) confirmed the location of the catheter tip after injection of 1â¯ml of contrast medium. We performed a series of standardized shoulder movements during a simulated shoulder physiotherapy session in cadavers. Following this, we administered 1â¯ml of methylene blue through the catheters, and then performed anatomical dissections to accurately identify the location of the catheter tips and compare them to their placement prior to the 'physiotherapy'. RESULT: CT imaging confirmed the location of the catheter tips at the suprascapular notch in all cases. However, following physiotherapy, 2 catheters (25%) were found to have migrated - specifically, 1 was located in the supraspinatus muscle, and the other was located in the trapezius muscle. CONCLUSION: Our findings suggest that catheter dislodgement may occur in approximately 25% of cases following simulated physiotherapy manipulation. However, further research is needed to determine the read incidence of catheter dislodgement in clinical practice.

This report describes the experience of removing migrated gastrointestinal (GI) stents using a gastrostomy (G) access. Four male patients aged 23-62 years (mean, 42 years) had 6 migrated stents removed using an existing (n = 3) or new (n = 1) G access. Removed stents included 5 covered esophageal stents that migrated into the stomach and 1 distal noncovered duodenal stent that migrated into the proximal duodenum. One patient had 2 stents removed during the same session. All stents were removed successfully without adverse events. Techniques used included the folding technique using a wire in 3 stents and forceps in 2 stents. Eversion technique was used in the duodenal stent. The G or gastrojejunostomy tubes were replaced after stent removal and used for enteral feedings. In conclusion, removing migrated GI stents using an existing or new G access was technically successful and safe.

BACKGROUND: Acupuncture, a traditional Chinese medical treatment, has been gaining popularity over the years. However, it also presents certain risks. We report a case of a patient who discovered a foreign body in their lung several years after undergoing acupuncture. CASE PRESENTATION: A middle-aged woman presented to our hospital with chest pain. An X-ray revealed a needle-like foreign body in the middle lobe of her right lung. The patient had previously undergone acupuncture treatment for local pain in her lower back and lower extremities many years prior. Based on the imaging findings and her medical history, we hypothesized that the foreign body in her lung was a result of a dislodged acupuncture needle. Through preoperative 3-dimensional reconstruction and indocyanine green localization, we were able to locate the foreign body in the lateral segment of the right middle lobe. We successfully removed the foreign body via wedge resection, and the patient made a smooth recovery post-surgery. CONCLUSION: Acupuncturists and surgeons should remain vigilant about the potential risks associated with acupuncture.
