CONTEXT Cystic lymphangiomas originate as benign masses which occur mostly in children especially in the head and neck region and/or the groin. Although abdominal lymphangiomas are rare, they are most commonly reported in adults. In addition, pancreatic involvement is rare. Lymphatic malformation with blockage of the lymphatic flow is the most common etiology leading to the formation of lymphangiomas. Cystic lymphangiomas should always be included in the differential diagnosis of abdominal masses which present with mass effect signs and symptoms. Due to its rarity, it forms a diagnostic and therapeutic challenge for the clinician. CASE REPORT We herein report the case of a 43-year-old man with a cystic lymphangioma detected in the head of the pancreas and describe the surgical procedure utilized as the therapeutic medium. CONCLUSION To remove this mass, we utilized a modified approach to a classic pancreaticoduodenectomy. This technique involved resection of the head of the pancreas while preserving the upper 2nd portion of the duodenum and the ampulla of Vater. The result of our 30-month follow-up of this patient has been very satisfactory with no complications.

BackgroundA significant proportion of surgical patients are unintentionally harmed during their hospital stay. Root Cause Analysis (RCA) aims to determine the aetiology of adverse incidents that lead to patient harm and produce a series of recommendations, which would minimise the risk of recurrence of similar events, if appropriately applied to clinical practice. A review of the quality of the adverse incident reporting system and the RCA of serious adverse incidents at the Department of Surgery of Ninewells hospital, in Dundee, United Kingdom was performed.MethodsThe Adverse Incident Management (AIM) database of the Department of Surgery of Ninewells Hospital was retrospectively reviewed. Details of all serious (red, sentinel) incidents recorded between May 2004 and December 2009, including the RCA reports and outcomes, where applicable, were reviewed. Additional related information was gathered by interviewing the involved members of staff.ResultsThe total number of reported surgical incidents was 3142, of which 81 (2.58%) cases had been reported as red or sentinel. 19 of the 81 incidents (23.4%) had been inappropriately reported as red. In 31 reports (38.2%) vital information with regards to the details of the adverse incidents had not been recorded. In 12 cases (14.8%) the description of incidents was of poor quality. RCA was performed for 47 cases (58%) and only 12 cases (15%) received recommendations aiming to improve clinical practice.ConclusionThe results of our study demonstrate the need for improvement in the quality of incident reporting. There are enormous benefits to be gained by this time and resource consuming process, however appropriate staff training on the use of this system is a pre-requisite. Furthermore, sufficient support and resources are required for the implementation of RCA recommendations in clinical practice.

Rheumatic heart disease (RHD) is a disease of poverty, is almost entirely preventable, and is the most common cardiovascular disease worldwide in those under 25 years. RHD is caused by acute rheumatic fever (ARF) which typically results in cumulative valvular lesions that may present clinically after a number of years of subclinical disease. Therapeutic interventions, therefore, typically focus on preventing subsequent ARF episodes (with penicillin prophylaxis). However, not all patients with ARF develop symptoms and not all symptomatic cases present to a physician or are correctly diagnosed. Therefore, if we hope to control ARF and RHD at the population level, we need a more reliable discriminator of subclinical disease. Recent studies have examined the utility of echocardiographic screening, which is far superior to auscultation at detecting RHD. However, there are many concerns surrounding this approach. Despite the introduction of the World Heart Federation diagnostic criteria in 2012, we still do not really know what constitutes the most subtle changes of RHD by echocardiography. This poses serious problems regarding whom to treat and what to do with the rest, both important decisions with widespread implications for already stretched health-care systems. In addition, issues ranging from improving the uptake of penicillin prophylaxis in ARF/RHD-positive patients, improving portable echocardiographic equipment, understanding the natural history of subclinical RHD and how it might respond to penicillin, and developing simplified diagnostic criteria that can be applied by nonexperts, all need to be effectively tackled before routine widespread screening for RHD can be endorsed.

Permanent pacemaker lead may damage the tricuspid valve in various ways, causing severe tricuspid valve regurgitation. The perforation of posterior papillary muscle is an uncommon complication caused by the lead. We describe a lead-sparing tricuspid valve repair in which the lead extraction was not an option. The papillary muscle containing the lead was fully mobilized to release the adherent leaflets. The repair was completed by commissuroplasty as well as ring annuloplasty, leaving the lead inside the implanted ring.

There is a paucity of low-fidelity and cost-efficient simulators for training cardiac surgeons in the aspects of aortic root/valve replacement. In this study we addressed this training challenge by creating a low-fidelity, low-cost but, at the same time, anatomically realistic aortic root replacement simulator for training purposes. We used readily available, low cost materials such as lint roller tubes, foam sheet, press-and-seal bags, glue, plywood sheet, heat-shrink sleeving tubes and condoms as the basic material to create a low-fidelity, aortic root, training simulator. We constructed a multi-purpose, anatomically realistic aortic root simulator using the above materials, both time- and cost-efficiently, using the minimum of surgical equipment. This simulator is easy to construct and enables self-training in major techniques of aortic root replacement as well as in stentless valve implantation for trainees in cardiac surgery.

CONTEXT Peripancreatic fluid collections are known complications of pancreatitis. The majority of fluid collections can be drained percutaneously under radiological guidance. Although radiological percutaneous drainage is regarded as safe, here it resulted in catastrophic haemorrhage from the colon due to an iatrogenic injury. CASE REPORT We present a case of a 70-year-old man who presented with acute alcohol-related severe necrotizing pancreatitis and an associated massive peripancreatic fluid collection. The drainage of this collection was attempted under computed tomography (CT) scan guidance. During the procedure the splenic artery and the splenic flexure of the colon were inadvertently damaged leading to life threatening per rectal bleeding requiring emergency angiographic embolisation of the splenic artery. CONCLUSION Radiological drainage of peripancreatic fluid collections is generally regarded as having lower rates of complications compared to surgical necrosectomy. However, in this case it leads to a life threatening per rectal bleed requiring emergency splenic artery embolisation.

We discuss the case of an experienced diver who ran out of air during his final ascent while scuba diving. He lost consciousness rapidly after surfacing and despite immediate cardiopulmonary resuscitation, could not be revived. On arrival at the emergency department he was noted to have copious amounts of blood in his upper airway and had developed extensive subcutaneous emphysema. Large amounts of air were observed in the central circulation following a postmortem computerized tomography scan as well as pneumomediastinum, a small right-sided hemothorax, and extensive subcutaneous emphysema. We discuss several potential pathophysiological mechanisms that might explain these findings. Finally, we end with a recommendation for an expedient whole-body postmortem computerized tomography scan and autopsy by a suitably qualified pathologist in the investigation of all dive-related fatalities, where possible.

Charles Bonnet Syndrome describes the triad of complex visual hallucinations secondary to ophthalmic pathology in psychologically normal people. We present a rare case of acute-onset Charles Bonnet Syndrome following cardiac surgery that resulted in profound loss of visual acuity in both eyes with characteristic visual hallucinations that were initially mistaken for delirium. Computed tomography of the brain revealed bilateral occipital infarcts, providing the substrate for Charles Bonnet Syndrome. A high index of suspicion should be maintained in cognitively intact patients with visual loss who are also experiencing visual hallucinations to ensure prompt diagnosis and management of this often overlooked condition.

Post-cardiotomy cardiogenic shock (PCCS) occurs in 2-6% of patients undergoing surgical revascularization or valvular surgery. Approximately 0.5-1.5% of patients are refractory to maximal inotropic and intra-aortic balloon counter pulsation (IABP) support. Refractory PCCS leads to rapid multi-organ dysfunction syndrome and is an almost universally fatal clinical state without advanced mechanical circulatory support (AMCS) i.e. extra-corporeal membrane oxygenation (ECMO) or ventricular assist devices (VAD). However, the associated major complications and cost related to such complex devices has led to centralization of such valuable services to only a few UK centers.
