Abstract

Background: The aim of this study was to look at the demography, sites of insertion, most common causes of foreign body ingestion and the procedures used for retrieval of these foreign bodies (FB). We also looked at length of stay and common a mental health diagnosis for patients admitted with FB ingestion.

Material & Method: This was a retrospective analysis of four years data from January 2014 to January 2018 at Northampton general Hospital. The data was collected using the hospital electronic record system. All patients admitted under surgical subspecialties and gastroenterology was included. Children with a genital FB were excluded from the study. The number of admissions for each patient was recorded. Patients were divided into accidental and mental health illness (MHI) groups.

Result: A total of 146 patients were admitted with FB diagnosis. 57% (84) were in the accidental group and 43% (63) were in the MHI group. In the accidental group 70% (54) were under the age of 16 years, the most common cause was inorganic FB and the most common site was an ENT. While in adults most common site in accidental FB was oesophagus and the food bolus was the commonest cause. In the MHI group 63 patients had 257 admissions episodes. The mean age was 25±21 years. Female sex and younger age i.e early adulthood were at a higher risk for FB ingestion. Abdominal x-ray was the most common investigation. Mean length of stay was 3±2 days. Endoscopic retrieval was successful in 85% of patients. Most common mental health diagnosis was deliberate self harm (DSH) 40%.

Conclusion: Younger age group, female sex and patients with history of DSH are at a higher risk of FB ingestion and recurrent presentation. Early recognition of high risk patients and prompt psychiatric help can minimise the recurrent presentation of these patients. Minimally invasive techniques like endoscopic retrieval of FB should be first choice.

Introduction

Patients with foreign bodies (FB) are common admissions to gastroenterology and surgical wards [1,2]. Patients with severe mental illness can be admitted on to a surgical ward with a variety of presentations ranging from foreign body ingestion, subcutaneous insertion, and introduction of FBs into natural orifices like the vagina, urethra or rectum. Foreign body ingestion into the gastrointestinal tract can lead to serious consequences with significant morbidity and mortality. Eighty percent of ingested foreign bodies which reach the stomach will pass uneventfully through the gastrointestinal tract (GI). Those which can’t pass through the GI track require either endoscopic or surgical intervention. It is important to understand that common mental health conditions leading to foreign body ingestion or insertion and to identify which patients are more likely to ingest complex foreign bodies.

Inedible substance ingestion increases the risk of ileus, poisoning, and suffocation and the long term consequences of ingestion of substances like detergents, acids etc are very poor. There is also a higher complication rate in patients repeatedly introducing FB under the skin or into the rectum or vagina. Complications range from damage to the surrounding structures to intestinal fistulae and peritonitis. This means prevention is important, especially in patients with mental health illnesses. Most of the patients with MHI, who are frequent attenders, are either in a psychiatric institution or under direct psychiatric observation [3]. we reviewed the data of all the patients who were admitted in our institute with a FB diagnosis which required surgical or endoscopic intervention for retrieval. We identified all the patients with a mental health illness for further analysis.

Method

Data for all the patients admitted with a diagnosis of a FB was retrospectively analysed covering the four year period from January 2014 to January 2018. Electronic discharge summaries, online PACS system for radiological investigations and operation notes were reviewed, which include details of presentation, investigations, management and documentation of any mental health problems.

Inclusion criteria

A. All patients with a diagnosis of FB from January 2014 to January 2018.

Exclusion criteria

A. Genital FB under the age of 16 years.

The patients identified were then divided into two cohorts; those with accidental FB and those with MHI. We reviewed patient demography, a history of FB ingestion (i.e. accidental, self-harm or sexual gratification) and the most common presentation (e.g. ingestion, subcutaneous insertion etc). We also looked at common investigations for diagnosis and common methods of retrieval. The length of hospital stay was recorded and for patients in the MHI cohort we reviewed any documentation of a psychiatric diagnosis and the number of repeated admissions for each patient.

Result

Over the four year study period, a total of 151 were identified with FB out of which 146 patients were admitted under surgery, urology and ENT departments. 57% (84) of these patients were in the accidental group and 43% (63) were in the MHI group. The common causes of FB insertion in these cohorts are shown in Table 1 the accidental cohort was further dived into paediatric and adult sub-groups. We found the majority 70% (58) of these patients were in the paediatric age group. The male to female ratio was 1.8:1 showing a slight male predominance and the mean age at presentation was 24.5±22 years. The most common site of foreign body insertion in the paediatric age group was the ear, nose and throat (ENT) followed by the oesophagus. In the adult group this was the oesophagus (i.e. food bolus). Table 2 shows the common sites FB in accidental group. Five paediatric patients with genital FB were admitted directly under paediatrics this was due to local child safeguarding policies.

These patients never had any surgical input so were excluded from study. In the MHI cohort among 63 patients, a total of 257 admissions for removal of a foreign body were recorded. We found the total number of procedures on individual patients ranged from 1 to 21 with a mean of more than four procedures per patient. The male to female ratio was 1:1.2 which a slight female predominance. The mean age at presentation was 25±21 years. Figure 1 shows the overall comparison of M:F ratio in the accidental and MHI cohorts, where the male predominance in the accidental group and female predominance in the MHI group can be observed.

Figure 2 shows the age distribution comparing both cohorts. There is a higher incidence of FB insertion in the younger population in both cohorts. The incidence of FB insertion in older patients in the MHI group is very small and is limited to learning disability patients only. The FB insertion in the accidental group actually starts to increase in old age due to cognitive dysfunction. Figure 3 Shows the documented psychiatric diagnosis in medical records and compares admissions in male and female patients. We found a female predominance toward deliberate self-harm (60%), followed by personality disorders (20%). Other diagnoses, in female patients, included psychosis (8%), post-traumatic stress disorder (6%), Compulsive sexual behaviour (CSB) 6. In male patients the most prominent diagnosis was sexual gratification (50%), followed by deliberate self-harm (17%). Other mental health diagnosis was personality disorder (11%), psychosis (8%), schizophrenia (7%) and learning disabilities (7%).

figure 4:Underlying mental health illness


Surgical and medical record and discharge letters from hospital admission were unable to classify sexual gratification and psychosis into underlying psychiatric illness and was found to be main short coming in understanding of psychiatric illness by medical doctors. The common sites of FB in patients with MHI were the oesophagus, stomach and subcutaneous tissue, shown in Figure 4. We found female patients had a higher incidence of FB in the oesophagus (43%) and skin (41%), compared to male patients were they were more commonly found in the stomach (49%) and rectum (31%). We found that out of 257 admissions 84 (30%) had no psychiatric diagnosis given on the discharge summary. The majority of these patients were those with FB in the rectum and urethra and these patients received no mental health assessment as part of their care. Table 3 shows the retrieval operation during this episode if we exclude the FB in subcutaneous tissue majority was removed endoscopically. The open removal by laparotomy was only 14% probably depending on mode of presentation i.e ingestion or insertion. There were a total of three deaths recoded, all with complications arising from FB ingestion, one was in the accidental group and two were in the MHI group. Those in the MHI group were both due to complications arising from repeated insertion of sharp objects subcutaneously leading to small bowel fistula Figure 5.

Discussion

Accidental FB ingestion is common in both extremes of life i.e children and in elderly people. Accidental FB is reported in children from 6 months to 6 years where they are exploring the world around them. As shown in our study the two extreme of accidental body were in children and elderly patients. While in intentional FB ingestion in patients with mental health problems are generally young adults who had various different diagnoses ranging from deliberate self-harm to personality disorders. This is slightly contrary to some of the medical literature where intentional FBs are reported more common in adulthood [3-4]. This is possibly due to separate child and adolescence mental health services in that area. FB insertion is a common presentation on surgical and gastroenterology wards. These patients can present to different surgical sub-specialities with different presentations i.e ingestion, insertion and introduction of FB in natural orifices for sexual gratification. The majority (90%) of foreign bodies will pass spontaneously, with 10-20% requiring endoscopic intervention. According to literature only less than 1% of the patients with FB ingestion will need surgical removal of these FBs [5]. Most of the studies recommend endoscopic retrieval as procedure of choice and claims it to be successful in most patients [6] similar results are shown in our study where endoscopic procedures are successful in most of the patients.

There is limited medical literature on genital FB for sexual gratification and there management. Most of these patients are discharged with out and psychological consultation or help possibly due to patient embarrassment and or lack of medical health professionals in recognising this behaviour as a psychological problem. As shown in our study there is significant number of patients with genital FB and most of them were discharged without and help. Many patients with a MHI and recurrent FB are frequent visitors to the general surgical wards and are difficult to manage. As shown in our study their frequent presentation of mental health patients repeatedly. These patients should be referred to psychiatric services during their index admission for help with their, often complex needs. For the best outcomes and to reduce re-admission, these patients are best managed as part of a multidisciplinary team with all members having awareness and basic knowledge of management and treatment of this patient cohort [7].

There are many guidelines available for the management of FB ingestion in patients with or without MHI but there are no guidelines or criteria for referral of these patients to psychiatric services, although evidence suggests referral for those patients who have history of psychiatric problems [8] and for cases involving unusual foreign objects or those with a history of foreign object insertion [9]. However, psychiatric problems associated with insertion behaviour may go unidentified without routine psychiatric consultation, which has lead to the recommendation for prompt psychiatric evaluation for all patients who self-insert foreign objects [10-16].

Conclusion

Patient with FB ingestion are young patients with a significant underlying MHI. These patients should have an early psychiatric referral with the aim of establishing a diagnosis, to minimise harm to the patient during the hospital stay and to help reduce future presentations, where possible endoscopic approach should be adapted to minimise the effects of repeated anaesthesia which can lead to worsening of mental health illness especially during acute settings.
