A rare case of cardiac tamponade masquerading as acute abdomen.

INTRODUCTION: Acute abdomen is any acute abdominal condition requiring a quick response. The incidence varies according to age and disease aetiology. The abdominal discomfort associated with extra-abdominal pathophysiology and thoracic conditions could mimic acute abdomen. In this case we report a rare case of a young patient with cardiac tamponade masquerading as acute abdomen. PRESENTATION OF CASE: A 25-years-old African man presented to the Emergency Department with abdominal pain. An EKG was performed, which revealed sinus tachycardia, with electrical alternans and borderline reduced voltage. At the time of the admission to our unit, he had a clinical worsening and a CT scan of abdomen was performed, which demonstrated hepatomegaly, abundant pericardial effusion and thin right pleural effusion at the lung bases. An echocardiogram confirmed a circumferential pericardial effusion with initial collapse of the right ventricular free wall. It was decided to immediately transport the patient to the Cardiosurgery Unit of another hospital to undergo pericardiocentesis. DISCUSSION: Our experience with this case underlines the important point that patients with a large pericardial effusion may present with the clinical features of acute abdomen and peritonitis. Abdominal pain was the primary symptom that prompted this patient to seek medical attention. CONCLUSION: Acute abdomen is any acute abdominal condition requiring a rapid, often surgical, treatment. Cardiac tamponade is a medical emergency. The differential diagnosis could be kept in mind by any emergency physician, surgeon and anaesthesiologist, because an incorrect diagnosis and therefore an incorrect treatment or a delay in pericardial evacuation can be life-threatening.

Giant Spigelian Hernia presenting as small bowel obstruction: Case report and review of literature.

INTRODUCTION: Spigelian Hernia is an uncommon pathology of abdominal wall (0.12-2.4%), usually small sized and with vague symptoms. It rarely presents as Small Bowel Obstruction or reaches dimensions that becomes clinically remarkable. PRESENTATION OF CASE: 84-year-old woman entered our Surgical Department for Small Bowel Obstruction due to a giant (8 × 7 cm) abdominal wall hernia, which was intraoperatively identified as Spigelian Hernia. We performed a minilaparotomy with reduction of viable small bowel and preperitoneal positioning of polypropilene mesh. Postoperative course was uneventfull. DISCUSSION: Due to its small dimensions and infrequence, the diagnosis could be challenging even if the patient undergoes a CT scan. The presentation with clear signs of small bowel obstruction associated with a large abdominal hernia is rare and suggests a urgent surgical approach with mesh repair to avoid recurrences. CONCLUSION: Even if rarely symptomatic, the Spigelian Hernia is an entity to consider in the differential diagnosis of small bowel obstruction in a virgin abdomen. Preoperative diagnosis, when available, is mandatory to guide a correct surgical approach.

Indocyanine Green Fluorescent Angiography During Laparoscopic Sleeve Gastrectomy: Preliminary Results.

INTRODUCTION: Indocyanine green (ICG) fluorescent angiography has been routinely applied for various laparoscopic procedures to evaluate the tissue blood supply. A promising branch for this technology is represented by bariatric surgery, especially to estimate the risk of gastric leak after laparoscopic sleeve gastrectomy (LSG), which seems mainly related to ischemia of the stomach. MATERIALS AND METHODS: 43 consecutive patients from January 2018 to March 2019 underwent in our institution LSG with intravenous injection of 5 ml ICG after the realization of gastric tube to evaluate the blood supply of the gastric tube. RESULTS: In all 43 cases, there have been no adverse events related to ICG. The vascular supply to stomach was estimated "satisfactory" along the stapled line in all cases. However, one patient showed signs and symptoms indicative of gastric leak in the fifth post-op day and diagnosis was confirmed by CT scan with Gastrografin. CONCLUSIONS: From our preliminary data, the intraoperative view of the blood supply of the stomach does not seem to represent a prognostic factor for the risk of gastric leak, suggesting a complex multifactorial etiology (intragastric hypertension? Abnormal inflammatory response?) which needs further data to be established.

Microscopic peritoneal carcinomatosis in gastric cancer: Prevalence, prognosis and predictive factors.

Peritoneal carcinomatosis (PC) is typically identified in advanced stage gastric cancer and is frequently considered to be an incurable disease. Along with macroscopic PC, microscopic PC may be diagnosed through pathological examination of tissue specimens and is not detectable during surgical intervention. The present study aimed to analyse the prevalence, prognostic value and predictive factors for microscopic PC. In the present retrospective study, data from patients with epithelial gastric cancer that were treated with curative intent surgery were examined. Patients with macroscopic PC were excluded. Additionally, the study population was divided into two groups based on the presence or absence of microscopic PC. The prevalence of microscopic PC was 5.5%. Microscopic PC exhibited a significant negative effect on overall survival. In addition, multivariate analyses revealed that the significant predictive factors for the presence of microscopic PC were adenocarcinoma of a diffuse type, lymphatic and vascular invasion, cancer location at the site of previous gastric surgery and a tumour extent >T2. In particular, the presence of lymphatic and vascular invasion was the most significant predictive factor. These results indicate that ≥5.5% of patients with gastric cancer who undergo surgery with a curative intent may benefit from more aggressive loco-regional treatment against microscopic PC at the time of surgery.
