ObjectiveTo explore the clinical treatment measures and etiology analysis of lower urinary tract and penile foreign bodies. MethodsWe retrospectively analyzed the etiology and diagnosis of 48 cases of lower urinary tract and penile foreign body in the Department of Urology of our hospital between 1993 and 2012. ResultsNine bladder foreign bodies were removed successfully by using cystoscopy; nine were removed through suprapubic cystotomy; urethral foreign bodies in 10 patients were successfully taken out by urethrascope; five foreign bodies were extracted by hand and forceps; rubber bands in 2 patients were cut off under local anesthesia; fretsaw was used to cut through the nested rings in 7 patients; dental drill was used to cut nesting materials in 3 patients; and 3 patients underwent penis skin circumcision overturn stripping ring extraction. No complications after urethral foreign body extraction occurred. ConclusionThe lower urinary tract and penile foreign bodies are easy to diagnose, but patients often conceal the etiology, so the natural history collection is very important in the diagnosis, and doctors should take appropriate methods to remove the foreign body after the diagnosis is confirmed.
ObjectiveTo explore the forensic pathology features of foreign body and its emergency treatment: Heimlich maneuver. MethodsWe carried out a review of relevant literature and autopsy findings of 8 cases of foreign body suffocation at West China Forensic Identification Center of Sichuan University from 2000 to 2012. ResultsThe most common foreign body reported was undigested food. Children, old people and middle-aged men who were drunk were vulnerable to choking. The most effective resuscitative procedure in such cases was Heimlich maneuver, but it had been noted to result in significant intra-abdominal and intra-thoracic injuries if performed incorrectly. ConclusionIt is necessary to take some preventive measures to avoid the foreign body, and the publicity of Heimlich maneuver to reduce the incidence and mortality of foreign body is important.
ObjectiveTo introduce a new method to remove the small foreign body in the hand or foot, and to discuss its feasibility and effectiveness. MethodsBetween May 2007 and March 2012, 78 patients with small foreign bodies embedded in the soft tissue of the hand or foot were treated with the method. There were 51 males and 27 females, aged from 7 to 69 years with an average of 32.5 years. The hand, wrist, and foot were involved in 48, 6, and 24 cases respectively. Foreign body type included fiberglass (57 cases), thorn (11 cases), iron (5 cases), bamboo thorn (2 cases), fishbone (2 cases), and metal needles (1 case). The time between injury and operation was 30 minutes to 16 days (mean, 2.6 days). The position and range of the foreign body were defined using the multipoint centralization method before removal surgery. The skin was cut according multipoint connection for finding small foreign body under a microscope. ResultsAll foreign bodies were successfully removed. The mean operation time was 6 minutes (range, 3-22 minutes). Healing of incision by first intention was obtained in all cases; no blood circulation disorders or infection occurred. All the patients were followed up 3 months-3 years (mean, 9 months). The distal limb had no feeling or movement disorders. ConclusionRemoval of small foreign body in soft-tissue using multipoint centralization method is safe and effective.
Objective To investigate the characteristics, complications, and influencing factors of pediatric foreign body ingestion, providing clinical references for prevention and management. Methods A retrospective analysis was conducted on pediatric cases of foreign body ingestion treated at West China Hospital of Sichuan University between June 2007 and September 2019. Patients were stratified by age into ≤5 years, 6-10 years, and >10 years groups. Foreign body types, impaction sites, and complication rates were compared across age groups. Univariate analysis and multivariate logistic regression were performed to identify risk factors for complications. Results A total of 610 pediatric cases of foreign body ingestion were enrolled. Foreign body ingestion predominantly occurred in children ≤5 years (n=472, 77.38%), followed by 6-10 years (n=100, 16.39%) and >10 years (n=38, 6.23%). Foreign body types varied significantly by age (P<0.05): coins predominated in ≤5-year-olds (57.20%), while food-related objects were most common in >10-year-olds (52.63%). The most frequent impaction site was the upper esophagus, accounting for 48.31%, 44.00%, and 60.53% in the three age groups, respectively. Univariate analysis identified age, foreign body type, and location as significant predictors of complications (P<0.05). Multivariate logistic regression demonstrated that oropharynx and esophageal impaction (reference: stomach) [odds ratio (OR)=4.699, 95% confidence interval (CI) (2.456, 8.996), P<0.001] and high-risk foreign body types [OR=3.538, 95%CI (2.045, 6.122), P<0.001] were independent risk factors for complications, whereas increasing age had a protective effect [OR=0.418, 95%CI (0.252, 0.694), P=0.001]. Conclusions Younger children are at higher risk of foreign body ingestion, while increasing age is protective against complications. High-risk foreign body types and oropharynx and esophageal impaction significantly increase complication risks. Strengthening parental education, preventive measures against high-risk objects, and enhancing clinicians’ vigilance for complex cases are essential to reduce complications.
