Clinical presentations and surgical management of liver hydatidosis: our 20 year experience.

BACKGROUND: Hydatidosis/echinococcosis of the liver is a very old problem in Greece and still exists, although it is declining. We have reviewed our 20 years' experience, and here we report the various clinical presentations of the disease and evaluate the clinical outcome of the surgical procedures performed. PATIENTS AND METHODS: We conducted a retrospective analysis of the past 20 years' medical records; 35 patients (males 34%, females 66%, mean age 58 years) were treated surgically. Results. The presenting symptoms or findings leading to the diagnosis of liver echinococcosis were jaundice (six cases, 17%), abdominal pain (five cases, 14%), gastrointestinal discomfort of the upper abdomen (e.g. nausea, vomiting, distention, anorexia) (two cases, 6%), acute pancreatitis (one case, 3%) and portal hypertension (one case, 3%). The rest of the cases were diagnosed incidentally (20 cases, 57%). External drainage and cystectomy with omentoplasty was performed in 21 cases (60%) and pericystectomy in 14 cases (40%). The mean hospital stay was 16.8 days. Morbidity and mortality were 18% and 3%, respectively, with no statistically significant differences between the two surgical approaches. The recurrence rate averaged 3%. DISCUSSION: A high index of suspicion is recommended when variable clinical manifestations of the upper abdomen are present. Meeting all criteria for surgical treatment of hydatid disease, external drainage and cystectomy should be the standard surgical procedure. Pericystectomy could be used for peripherally located liver cysts that are only partially surrounded by parenchyma. Resection procedures are considered too radical for a benign disease. Appropriate randomized controlled studies are needed to establish the definite surgical management of liver hydatidosis, including modern techniques such as laparoscopy and transcutaneous puncture under US guidance (PAIR technique).

The treatment of chronic anal fissure with botulinum toxin.

BACKGROUND/AIMS: The aim of this study was to evaluate the effectiveness of botulinum toxin for the treatment of uncomplicated dorsal chronic idiopathic anal fissure. MATERIAL AND METHODS: Forty-five patients who reported post defecatory anal pain since two months or more were given a total of 20U botulinum toxin in the anal sphincter apparatus on both sides as well as below the anal fissure. RESULTS: Thirty-seven patients received a second session of 25U botulinum toxin injection. Thirty-five patients (78%) presented completely healed anal fissure, while ten needed lateral internal sphincterotomy. All patients were followed up for 8-36 months. Two patients relapsed. CONCLUSION: Local injection of botulinum toxin is a new and safe treatment; however, two sessions of injections are necessary to be effective and long-term follow-up to assess the recurrence rate of fissure is needed to evaluate further this method of treatment. Partial internal lateral sphincterotomy is no more the treatment of choice for chronic anal fissure.

Aortic transsection after blunt chest trauma.

We report a case of an 18-year-old female who developed an extensive hemothorax after blunt chest trauma. Transesophageal echocardiography (TEE) showed transsection of the aorta at the level of the isthmus and turbulent flows in several places around the aorta. We discuss the contribution of TEE for detecting traumatic injuries to the thoracic aorta.
