Colonic lipomas. Three surgical techniques for three different clinical cases

Colonic lipomas larger than 2 cm in diameter are likely to be symptomatic. In some cases a complication is the first clinical sign. Massive lower intestinal bleeding or obstruction, acute bleeding, prolapse or perforation or, rarely, acute intussusception with intestinal obstruction require urgent surgery. Diagnosis is often made following colonoscopy, which can also have a therapeutic role. Imaging procedures such as CT has a secondary role. Patients with small asymptomatic colonic lipomas need regular follow up. For larger (diameter > 2 cm) and/or symptomatic lipomas, resection should be considered, although the choice between endoscopic or surgical resection remains controversial. We believe that even lipomas > 2 cm can safely be removed by endoscopic resection. If surgery is indicated, we consider laparoscopy to be the ideal approach in all patients for whom minimally invasive surgery is not contraindicated.

Ocular traumatology in children. A retrospective study

Obiective. This study assesses the descriptive epidemiology of children with eye injuries presenting to the Emergency Department of a non exclusive Paediatric University Hospital - First Division of Ophthalmology of “Sapienza” University of Rome - over a period of 12 years. Study Design. A retrospective long term study of 12 years. Participants. All paediatric patients (up to 14 years of age) presenting with ocular injuries and hospitalized. Methods. It was analyzed the incidence of the ocular trauma among males and females. The situation in which the trauma occurred, type of trauma (contusive or perforating), the presence of endo-bulbar foreign bodies, visual acuity outcome. Results. There were 203 patients who presented to the Emergency Department in the period examined. Contusive traumas were 130 (90 males, 40 females). The perforating trauma were 73 (63 males, 10 females). The presence of an endo-bulbar foreign body was registered in 10 patients. A detailed analysis of the causes of the trauma is therefore provided. We evidence that males were almost exclusively involved in sport traumas (60 males versus 2 females), and in second instance accidental trauma is almost equally divided between two genders. Conclusions. Our retrospective study presents the paediatric cases of a non exclusive Paediatric University Hospital where 3% of ocular traumas requiring hospitalization were in children. Therefore our data could be useful in order to bring about the necessary preventive measures to minimize paediatric eye injuries.

How new imaging techniques can aid in defining the cardiovascular profile of the high-risk patient

Cardiovascular prevention has been developed in the last eight years producing an ever increasing amount of data requiring frequent updating. Studies using angiography to determine change in coronary obstruction have indicated progression, stabilization, or regression of coronary lesions associated with changes in plasma lipids and lipoproteins. Moreover, the guidelines on arterial hypertension published in 2007 listed the risk factors affecting prognosis but even by 2009 an update modified not only the list of risks, but even the philosophy behind the thought process which introduced as essential element in the prognosis of hypertension the ascertained existence of a damaged organ. Thus, the documentation of atherosclerotic vascular disease (plaques) and the quantification of its extension in the arterial tree became a determinant in the definition of cardiovascular risk. Magnetic Resonance (MRI) and coronary computed tomography (coro CT) applied to the heart and large vessels are the most promising methods.

Pre-operative ultrasound for breast tumour measurements: is there potential for mismanagement?

The pre-operative size of breast tumour is the most important factor in determining feasibility of breast conserving surgery in operable breast cancer. Currently there is no consensus on the most accurate modality to measure tumour size. A prospective study of consecutive and unselected symptomatic patients with invasive breast cancer who had primary surgery between January 2006 and December 2007 was conducted. Patients with multi-focal and multi-centric tumours were excluded. The aim of this study was to find the correlation between histological size of invasive breast cancer and pre-operative tumour size as measured by ultrasound. Over this two year period, data for 192 patients was analysed for this study. The mean tumour diameter on ultrasound and histology was 19.5mm and 29mm respectively. The difference between the means in the two modalities was found to be statistically significant (P<0.001).Ultrasound underestimates the true size of breast tumours as determined histologically. Inaccurate tumour size measurements may result in re-operations to achieve adequate margins.

Two cases of right atrial myxoma in redo patients. A mere coincidence?

We describe two cases of right atrial myxoma in redo patients who had previously undergone to coronary artery by-pass grafting (CABGs) and mitral valve replacement respectively. Both of patients experienced effort dyspnea and were assessed by trans-thoracic echocardiography, revealing the right atrial masses. They were operated on for myxoma resection and postoperative course was uneventful. Our report deals with the interesting topic of the location of benign masses that are usually more common in the left atrium. Should we hypothesize that the right atrial manipulation during the previous surgery induces the onset of the right atrial mass? It is an interesting matter to debate.

Parotid gland oncocytoma in HCV-positive patient with non-Hodgkin's lymphoma. Case report

We report a case of parotid gland oncocytoma in a patient with chronic infection from hepatitis C virus (HCV) and associated non-Hodgkin's lymphoma and xerophthalmia. Our case confirms the triple tropism of the HCV: hepatotropism, lymphotropism and sialotropism.

Diagnosis of intra-abdominal injuries can be challenging in multitrauma patients with associated injuries. Our experience and review of the literature

ntroduction. Trauma is the most common cause of death and disability among patients during the first four decades of life. Abdominal trauma is reported to be the 3rd most common injured region. Clinical examination may be unreliable in the evaluation of these patients especially in the presence of associated injuries. Therefore the use of diagnostic tools is essential in the management of the injured patient with abdominal trauma and additional injuries. Patients and Methods. During 1 year period from December 2010 to November 2011 we recorded the patients that presented to the emergency department of our hospital and were found to suffer from intra-abdominal injuries. These patients were divided in two groups depending on whether they had additional comorbid injuries or not. Several parameters were recorded and compared between the two groups, such as mechanism of injury, general status and hemodynamic stability of the patient on presentation, physical examination, use of imaging modalities and concomitant findings, need for surgical intervention and mortality rates. Furthermore the discrepancy between physical findings and final diagnosis after the use of diagnostic adjuncts is reported. Results. We recorded 31 patients with abdominal trauma. 13 (42%) patients were found to suffer from abdominal trauma and associated injuries (Group I), whereas 18 (58%) presented with abdominal trauma alone (Group II). The patients of the first group presented hemodynamic instability in 38% of cases while the patients of the second in 22% of cases. Reduced consciousness was present in 38% in group I versus 17% in group II. Signs of abdominal injury during clinical examination were present in only 15% in group I versus 72% in group II that represented a remarkable difference between the two groups. Conservative treatment was possible in 15% of patients with additional injuries and in 22% of patients with abdominal injury alone. In group I there were two deaths whereas in group II all patients survived. Conclusion. In patients with abdominal trauma, associated injuries seem to add to the severity of injury and indicate a worse prognosis. Clinical examination is unreliable and misleading in the majority of these patients and the use of diagnostic tools cannot be overemphasized.

Recurrent gallstone ileus: case report and literature review

The gallstone ileus is a rare complication of cholelithiasis and it represents the 1-4% of small intestinal mechanical obstruction. Gallstone is generally wedged in the terminal ileum, even if unusual locations have been described. The literature reports a very high morbidity and mortality, often because misdiagnosis or delayed diagnosis. There is no unique opinion in literature about the choice between one-stage and two-stage surgery. We report a clinical case that summarizes the diagnostic and therapeutic difficulties of gallstone ileus.

Endovascular treatment of multiple anomalous splenic artery aneurysms in a Jehovah witness

Purpose. The present report describes a full endovascular treatment of a multiple anomalous (Splenic artery aneurysms) SAA with combination of coils embolization and proximal occlusion of the splenic artery with the Amplatzer vascular plug. Case report. A 53-year-old Jehovah witness woman presented with multiple aneurysms arising from an anomalous splenic artery. An endovascular treatment was performed by implantation of multiple coils and an Amplatzer Vascular Plug. A CT scan 2 months after the procedure showed complete thrombosis of the aneurysms. Discussion. Aneurysms involving an anomalous or aberrant splenic artery are rarely reported in the literature. Their surgical treatment involves potential difficulties as a consequence of anatomical position and vascular anomalies. A fully endovascular technique can be much more attractive compared to any surgical management, providing an effective and minimally invasive option. Splenic artery - Aberrant splenic artery - Aneurysm - Endovascular treatment - Jehovah witness.

Simultaneous Meckel’s diverticulitis and appendicitis: a rare complication in puerperium

We report a case of a 24-year-old woman who was delivered via cesarean section at 39 weeks and presented in the puerperium with symptoms of worsening abdominal pain and septicaemia. Preoperative ultrasonography suggested the presence of a pelvic collection. Explorative laparotomy revealed the simultaneous presence of Meckel's diverticulitis and appendicitis without bowel perforation. The patient made an uneventful recovery following small bowel resection with end to end reanastomosis and appendicectomy.

Small bowel obstruction caused by mesh migration. Case report

Introduction. Endoscopic hernia repair methods have become increasingly popular over the past 15 years. Nonetheless, there is no consensus regarding an optimal fixation method. Transabdominal sutures and titanium tacks or staples are the most traditional ones. Case report. We present a case of mechanic small bowel obstruction due to mesh migration occurring one year and a half after incisional hernia repair with polytetrafluoroethylene mesh fixed by spiral tacks. Discussion. Titanium spiral tacks are dangerous because of their sharp components, which can damage organs such as the small intestine, by causing microperforations. The type of prosthesis used has also contributed to the intraluminal migration, since polytetrafluoroethylene mesh is very flexible and poorly integrates in the abdominal wall. Conclusion. A prosthesis of a different material combined with a different fixation system such as absorbable tacks, biological glue, or mechanical tacks without sharp components, would have obviated mesh migration. .

Duodenal tumors: four case reports

We report 4 cases of neuroendocrine tumors of the duodenum. Signs and symptoms were non-specific. The choice of surgery depended on the site and stage of the tumor and any concomitant diseases.
