284 Wunderlich Syndrome - Case Report of a Surgical Emergency Due to Spontaneous Non-Traumatic Retroperitoneal Haemorrhage
Authors: Patil S , Prakash Narayan P , Henderson J 
Published: October 2021

Abstract
A 42-year-old female with no other significant co-morbidities presented with complaints of sudden onset abdominal pain, she was in state of shock- her haemoglobin dropped drastically to 6.8g/dl from 11.8g/dl. She was resuscitated and was given blood transfusion.
CT Scan was suggestive of retroperitoneal haemorrhage due to rupture of Renal angiomyolipoma (RAML). Patient underwent selective embolization of renal artery the next day and was discharged after 3 days of post-operative stay.
Wunderlich Syndrome-is a rare condition in which spontaneous nontraumatic renal haemorrhage occurs into the subcapsular and perirenal spaces is most commonly caused due to spontaneous rupture of RAML.It is characterized by Lenk’s triad – Acute flank pain, flank mass, hypovolemic shock. Size of AML (&gt;4 cm), prothrombotic states such as pregnancy are main causes of AML rupture. Patients are managed conservatively or with help of selective arterial embolization. Nephrectomy is last resort in a hemodynamically unstable patient or in cases of embolization failure.
When dealing with acute abdomen with haemodynamic instability in non-traumatic cases it is essential to consider possibility of Wunderlich Syndrome. Early diagnosis, availability of Interventional radiology is key to successful management and potentially avoiding a Nephrectomy.
304 First Reported Case of Metachronous Tumours With Delayed Recurrence from The Neuroendocrine Tumour Arising in A Tailgut Cyst
Authors: Basit R H , Khan R.BN 
Published: October 2021

Abstract

Background
Malignant transformation of tailgut cysts (benign retrorectal cysts) into Neurodendocrine tumours (NETS) is extremely rare with less than 30 reported cases in the literature. A tiny proportion of these cases report early recurrence (within 2 years) and to our knowledge none have reported delayed recurrence 6 years after primary resection.

Case history
We report a 55-year-old male who underwent laparoscopic excision of a 5 cm presacral tumour found incidentally and confirmed histologically to be a G1 NET (WHO Classification) arising from a pre-existing tail gut cyst, with no evidence of metastasis.16 months later the patient presented with bowel obstruction secondary to adenocarcinoma of the colon at the splenic flexure. The patient underwent laparoscopic left hemicolectomy; histology confirming a moderately differentiated adenocarcinoma (TNM stage pT3pN0). The patient underwent adjuvant chemotherapy post-operatively based upon immunohistochemistry. The patient was followed up for both tumours with CEA, serum chromogranin A, colonoscopies, and CT scans. At 5th year post hemicolectomy, CT scan revealed a new asymptomatic 18 mm left internal iliac lymph node which was avid on octreotide scan consistent with metastasis secondary to NET resected previously. He, therefore, underwent 30Gy sabre radiotherapy.

Conclusions
There is no consensus regarding follow up duration post early NET resection. The recurrent NET was picked up incidentally as part of the 5-year colorectal adenocarcinoma follow up at our unit. The recurrent NET would not have been identified had this not been a metachronous case. Thus, consideration must be given to both radiological and biochemical follow up post NET resections.
344 Managing Clinical Rarities: A Unique Case of Non-Inflamed Appendix in A Port Site Hernia
Authors: Tribedi T , Kulkarni N 
Published: October 2021

Abstract

Introduction
Port site hernias containing the appendix are sporadically described in the literature, with most cases presenting with acute appendicitis. Cases of a normal appendix being found in such hernias are extremely rare and rarely published. Here we describe a patient with a port site hernia containing a non-inflamed appendix. The lack of similar recorded cases makes this a unique case to highlight and discuss.

Case Description
81-year-old lady, with adenocarcinoma of the upper rectum, underwent a laparoscopic high anterior resection in late 2018. With 12 mm ports placed in Umbilicus and RIF. 5mm ports placed in RUQ and LUQ. The 12 mm ports were closed with deep suture closure and the skin was closed using clips. Computerised tomography (CT) imaging at one year showed local cancer recurrence and a small abdominal wall hernia in the right iliac fossa. During subsequent resection surgery, a RIF port site hernia was identified intraoperatively. The hernia sac consisted of an uninflamed appendix. The hernia was reduced and an appendicectomy was performed with the hernia being closed with interrupted suture closure. Histology of the appendix confirmed no evidence of inflammation.

Discussion
When a clinical rarity is encountered there is often minimal literature to guide management and decisions must be made based on surgical principles and clinical reasoning. Although here an appendicectomy was performed, resection of a normal appendix remains a contentious point in the surgical field. This case demonstrates a potential management option to guide surgeons who encounter this clinical rarity in their future practice.

Abstract

Introduction
Anterior skull base cerebrospinal fluid (CSF) leaks are managed successfully with endonasal surgery. Endoscopic closure of CSF leaks from posterior table of the frontal sinus remains challenging. Vascularized Hadad-Bassagasteguy flap (HBF) reconstruction of the skull base has increased CSF closure rates but does not extend to frontal sinus. We describe our technique using septal flap pedicled by anterior ethmoid artery (AEA) for repairing frontal defects.

Method
Retrospective review of cases of frontal CSF leak repair using the AEA flap reconstruction. Flap design: an anterior vertical septal mucosa incision at posterior border of the frontal sinusotomy is made and extended to nasal floor. Posterior vertical incision is made 1 cm posterior to the projection of the axilla of the middle turbinate on the septum and extended to nasal floor. A horizontal incision along the nasal floor joins the two incisions. The flap is raised and rotated into the frontal sinus over the posterior table reconstructed defect.

Results
Three patients identified. Two males, one female, aged 11, 33 and 56. Patient histories included recurrent bacterial meningitis following head trauma, recurrent sinusitis and fronto-ethmoidal osteoma, with intraoperative CSF leak and CSF rhinorrhea due to meningoencephalocele. The three posterior wall defects were successfully repaired endoscopically with multilayer reconstruction and the AEA septal flap.

Conclusions
The anterior ethmoid artery septal flap can be successfully utilised for frontal CSF leak repair. Flap is conveniently located for frontal sinus defects. When the septum is intact it provides an excellent final layer as part of multilayer reconstruction.
477 Surgical Solutions and Problems in An Adult Patient with VACTERL Association
Authors: Smith H , Hargest R 
Published: October 2021

Abstract

Background
We report an adult patient with features of VACTERL - oesophageal and anal atresia, with cardiac malformation. In infancy he underwent colonic interposition for oesophageal atresia using the transverse colon as a conduit. As a teenager he underwent formation of a Koch continent ileostomy after previous stoma formation for anal atresia. Eventual failure of the Koch pouch nipple valve necessitated a laparotomy for attempted refashioning. Unfortunately, this operation was beset by life-threatening complications and a protracted post-operative course. He presented to our hospital with a laparostomy, high output enterocutaneous fistulae (ECF) necessitating home total parenteral nutrition (TPN), severe cachexia and deconditioning.

Method
Conservative therapy was utilised to improve the nutritional and physiological status of the patient. Simultaneously, attempts were made to define the anatomy of his abdomen in relation to previous surgery. However, operation notes for the original procedures (oesophageal reconstruction and Koch pouch formation) were lost due to closure of the hospital which he attended at the time.
A laparotomy was subsequently performed to manage the ECFs. Most of the small intestine was unsalvageable due to multiple fistulae and adhesions, leaving 35cm of small bowel terminating in an end ileostomy. A cholecystectomy was performed to mitigate gallstone formation.

Conclusions
Efficient communication is imperative in the management of complex patients. The loss of original operation notes made interpretation of subsequent imaging and planning of surgery troublesome. In contrast, efficient communication between teams involved in his peri-operative care, particularly the respiratory and intensive care teams facilitated a smooth post-operative course and successful discharge from hospital.
549 Use of 3D Printing Technology in Surgical Planning and Decision Making in ENT Skull Base Surgery- An Axial 3D First in Northern Ireland
Authors: Mallon A , Farnan T 
Published: October 2021

Abstract

39-year-old male seen at ENT clinic with inverted papilloma polyp of nasal sinus. CT showed multi-sinus mucosal thickening. The surgical options discussed were modified Lothrops endoscopic sinus surgery or an open approach of frontal sinuses with osteoplastic flap and septorhinoplasty.
A model 3D skull was created by Axial 3D using stereolithography 3D printing technology with photopolymer resin. The skull was made in 1:1 scale with tolerance of 0.2mm. The tumour was printed in a contrasting colour, which allowed clear visualisation and appreciation of tumour boarders and relations to surrounding structures.
The patient underwent FESS with modified Lothrops approach, achieving good clearance of polyp. The operation resulted in relief the patient’s symptoms.

Discussion
The use of a 3D model allowed for visualisation of tumour size and relation to surrounding anatomy, particularly the absence of dural involvement within the fontal sinus. It assisted in surgical planning. The use of the 3D skull was beneficial for patient as it allowed less invasive surgery and therefore shorter recovery time. It was also beneficial for the hospital organisation as it lowered resource requirements of theatre time, hospital bed days and staff resources. One limitation of the 3D printed skull was that the fine lamellae ethmoid air cells were not shown due to the manufacturing process.

Conclusions
The use of 3D printing is becoming increasingly popular as a surgical aid. We found the use of the 3D skull to be useful in individualised surgical planning for endoscopic sinus surgery.
554 An Unusual Case of a “Hernia Within a Hernia” Resulting in Small Bowel Obstruction and Strangulation
Authors: Mallon A , Skelly R , Beirne C 
Published: October 2021

Abstract

59-year-old female presented with symptoms of small bowel obstruction. She had a history of previous open right hemi-colectomy. She also had a previous complex strangulated ventral hernia which had required laparotomy and repair. Following this the patient had recurrence of the ventral hernia.
Examination demonstrated a non-tender irreducible recurrent ventral hernia in a patient with a high BMI (&gt; 40). CT reported a midline hernia containing dilated small bowel loops. Additionally, there was a separate narrower hernia arising from the original larger hernia containing a strangulated loop of small bowel.
Emergency laparotomy was performed. At operation there was a large hernia containing a smaller secondary hernial defect. Within this secondary defect, there was a loop of jejunum with a constriction band. which was released. There was no vascular compromise to the bowel and no need for resection. The hernial sac was excised and the abdominal wall repaired. Post-operative recovery was uneventful.

Discussion
The patient had a known, recurrent wide necked ventral hernia. However, this was the first presentation of the new, smaller hernia. This case is unusual in that it demonstrates a multi-locular “hernia within a hernia”. Although multi-locular hernias have been previously described, there is a paucity of literature on these.

Conclusions
This “hernia within a hernia” is an uncommon surgical finding for which there is limited literature. Clearly without urgent surgical intervention there would be an increase in morbidity and mortality.
559 One Mesenteric Defect, Two Segments of Colon, A Number of Surgical Strategies! A Rare Case of An Internal Hernia Causing Bowel Ischemia
Authors: Devani P , Al-Saadi N , Bowrey D 
Published: October 2021

Abstract
Internal hernias due to mesenteric defects are a rare cause of bowel obstruction, but once present their complications are associated with a high morbidity and mortality. We present the case of a 24-year-old patient who presented to the emergency department with signs and symptoms of an acute abdomen. Following surgical review, taking into consideration the patient’s clinical, biochemical, and radiological findings, the patient was taken for immediate emergency surgical exploration. A laparoscopic approach was initially taken, which revealed dilated and ischemic colon, and therefore an open approach was then adopted. Operative findings included a very mobile caecum and proximal ascending colon which had herniated through a defect in the small bowel mesentery, the sigmoid colon had subsequently become incarcerated by the caecum and small bowel too. Both the ascending and sigmoid colon had become ischemic. A number of surgical strategies were considered, and given the patients age it was decided to preserve as much normal bowel as possible. Thus, a right hemi- and sigmoid colectomy were performed with an ileo-transverse anastomosis and formation of an end colostomy. In this case, radiological diagnosis pointed to a suspicion of an internal hernia, and operative diagnosis highlighted a rare mesenteric defect causing herniation and subsequent ischemia. Relying on the patient’s clinical condition and an early decision for surgical intervention resulted in a positive outcome for outpatient. The patient made a good recovery following the bowel preserving surgery.
560 Case Report: A Very Rare Case of Incidentaloma of a Large Adrenal Cavernous Haemangioma
Authors: Chua Y , Quake S , Prasad K , El-Saify W 
Published: October 2021

Abstract

Introduction
Incidentaloma are asymptomatic and unanticipated adrenal tumours found on radiological imaging for unrelated diagnostic inquiries. Adrenal cavernous haemangioma is a rare, differentiated and benign tumour arising from the endothelial layer of blood vessels. This is a rare phenomenon with only 66 cases reported in the literature between 1955 and 2018.

Case Details
This is a case of a 79-year-old Caucasian gentleman who presented in March 2020 with vague abdominal discomfort and anaemia on a background of multiple co-morbidities including in particular, an asymptomatic left 5.6cm adrenal incidentaloma found in 2014. A computed tomography scan of abdomen-pelvis in June 2020 revealed progression in size of the incidentaloma to 20.8cm. Biochemical tests confirmed non-functioning adrenal tumour. The patient underwent open left adrenalectomy, left nephrectomy, splenectomy and distal pancreatectomy. The diagnosis of adrenal cavernous haemangioma was subsequently made on histopathological examination. Post-operatively, our patient made a good physiological recovery.

Discussion
There are no established diagnostic and treatment guidelines for adrenal cavernous haemangioma. Larger tumours are often treated surgically to exclude malignancies and to prevent potential complications as well as symptom relief. Literature reviews showed that most cases were surgically managed, and diagnoses were made through histology post-operatively.

Conclusions
Adrenal cavernous haemangioma typically present as incidentalomas which require further investigations. They are very rare non-functioning benign tumours that can be difficult to be differentiated from other adrenal malignancies.
581 Renal Arteriovenous Fistula Percutaneous Embolization Using the Amplatzer Vascular Plug II

Published: October 2021

Abstract

Introduction
Renal arteriovenous fistula (AVF) is not considered a common condition; however, it can occasionally complicate with renal impairment and heart failure secondary to high cardiac output. Recently, percutaneous embolization has overcome traditional surgery as the first line of its management, because of better success rates as well as less morbidity and mortality.

Case report
A 68-year-old male who presented with a renal AVF post left partial nephrectomy associated with a large pseudoaneurysm. This was found on a computed tomography angiography (CTA) scan, a routine follows up for his endovascular aortic aneurysm repair. Due to the patient’s co-morbidities and to avoid the potentially fatal pseudoaneurysm rupture, a minimal invasive approach was agreed in the multidisciplinary meeting. He was treated by percutaneous transcatheter embolization using the Amplatzer Vascular Plug II (AVP-II) through a right femoral arterial access. The patient recovery was uneventful, following an overnight stay he was discharged home. CTA done four and ten months later showed the AVP-II device inside the left renal artery branch feeder with no artifacts seen. There was absence of recanalization of the AVF. In the literature, adopting the transarterial route for the renal AVF treatment with AVP-II device as a single embolotherapy device has not been reported before.

Conclusions
Our report display the feasibleness of AVP-II in renal AVF treatment by arterial feeder embolization, specifically in fistulas with high flow and short communication as our case in which it showed offered multiple advantages over coils and is more cost effective.
586 Peri-Pancreatic Migration of Lost Intra Uterine Device: Case Report and Review of Literature
Authors: Bhattacharya P , Amada H , George A 
Published: October 2021

Abstract
Intra uterine devices (IUDs) is one of the most effective form of contraception available today. Uterine perforation and IUD migration is a rare but serious complication and is reported to occur in 0.05 to 13 cases out of 1000 IUCD placements. Migration of IUD to pelvis and lower abdominal organs following uterine perforation has been reported widely in literature. However far migration into the upper abdomen in very rare. Here we report a case asymptomatic peri-pancreatic migration of IUD.
A 65-year-old lady being investigated for pneumonia was picked up to have an asymptomatic IUD lying in front of the pancreas. The patient recalled having a hormonal Mirena coil placed 12 years previously for menopausal symptoms. Routine 3-year general practitioner follow-up failed to detect the IUD on vaginal examination. The patient denied spontaneous IUD discharge. However, three subsequent pelvic ultrasound scans did not detect any retained IUD and she was discharged as unrecognized IUD expulsion. She remained asymptomatic for the next 12 years with no abdominal symptoms though she did report to the General Practitioner, multiple episodes of new onset hot flushes when opening bowels - which was managed conservatively with reassurance.
It was decided to surgically remove the IUD. Intraoperatively, the IUD was found densely adherent to the lesser omentum close to the pancreas and stomach and was removed safely laparoscopically. The patient made a good postoperative overnight recovery and was discharged.
Intra-abdominal migration of IUDs is a very rare complication of IUD insertion and when detected should be promptly treated with Laparoscopic removal.
592 A Large Lipoma: An Unusual Presentation of the Tongue
Authors: Shathur A , Rashid A , Patel V , Ffolkes L , Jayaram R 
Published: October 2021

Abstract

Background
Lipomas are commonly identified tumours of the body however they are rarely found in the oral cavity. Rarer still is it to report a case of a lipoma in the tongue as they are more commonly located in the buccal mucosa.

Objectives
To diagnose and explore the pathogenesis of a soft-tissue swelling of unknown origin

Method
A thorough patient history and clinical examination was undertaken followed by magnetic resonance imaging (MRI) which revealed an alarming report at first glance. An incisional biopsy of the lesion was then carried out to aid in diagnosing the lesion.

Results
The swelling caused the patient no pain however the mere size of the lesion affected the patient’s tongue movement and function which therefore affected the patient’s quality of life. The imaging and the biopsy of the lesion led to a diagnosis of a large lipoma on the lateral border of the tongue.

Conclusions
To the authors’ best knowledge, we present a rare case of a patient whom we diagnosed with a large lipoma on the lateral border of the tongue. This case report discusses the stages of patient management from initial presenting complaint, up to the maintenance of the patient following the diagnosis of this lesion.
597 Counting on You to do The Count: An Unusual Case Report of a Delayed and Missed Gossypiboma Secondary to Swiss Cheese Model Failings
Authors: Amin P , Chan T 
Published: October 2021

Abstract

Introduction
Gossypiboma is a term describing a retained surgical swab which is a serious complication following any surgical intervention. The incidence of these cases is wholly under reported, partly due to medicolegal aspects, but also due to the misnomer of diagnosis. In this case, we discuss the multifactorial deficiencies which led to a significant morbidity in a patient who had remained asymptomatic for nine years since index surgery.

Case Presentation
A 40-year-old woman presented to the emergency department febrile with a one week history of abdominal pain, on a background of a one year history of chronic pain. The patient’s surgical history demonstrated an ovarian fibroid excision and a subtotal hysterectomy nine and six years ago, respectively. It was later noted the chronic abdominal pain had been previously investigated with positive findings on imaging and biopsy, however, she was lost to follow up. A year later, she presented with an acute abdomen and operative findings of a large abscess cavity, containing a retained swab, with small bowel fistulation were noted.

Conclusions
This reiterates the importance of surgical safety checklists, and often despite this there are many factors that can eventually lead to complete alignment of the holes in the Swiss Cheese leading to unfavourable outcomes. It is imperative to remain hypervigilant during checkpoints, particularly in emergencies where the unpredictability of the operation leads to human error. Gossypiboma remains a serious cause for morbidity and mortality, thus the potential for modified safety checklists or alternative methods for surgical counts.
