Hydatid disease of the abdomen and other locations.

We present patients treated for hydatid disease in our hospital (in northeastern Greece) over the last 20 years. In the period from 1984 to 2003, a total of 135 patients (54 male, 81 female) were treated for echinococcal disease (age 15-85 years). In 111 (82.2%) patients only the liver was affected; 9 (6.7%) patients had concomitant hepatic and extrahepatic hydatid disease; and 15 (11.1%) patients had only extrahepatic disease. Clinical symptoms in patients with hepatic locations of the disease included abdominal pain localized in the epigastrium or right upper quadrant of the abdomen, tenderness, hepatomegaly with palpable abdominal mass, jaundice, fever, and anaphylactic reaction. All the patients were treated surgically. Surgical techniques included partial cystectomy and drainage, cystectomy and capitonage, cystectomy and omentoplasty, only drainage, left lateral hepatectomy, total pericystectomy, and laparoscopic pericystectomy. Rupture into the bile duct was managed by T-tube drainage or biliodigestive anastomosis. Symptoms and surgical treatment for extrahepatic cysts varied according to the location of the cyst. The median cyst diameter of all patients was 11 cm. The postoperative complication rate was 17.0%. Two patients died (1.5%). The median hospital stay was 18 days. The recurrence rate was 6.7%. The study suggests that treatment of this benign disease should be the less radical surgical technique combined with pre- and postoperative anthelmintic administration. The surgical treatment should be combined with careful use of scolicidal fluids and aspiration of the cyst to avoid contamination and minimize the risk of recurrence.

U-stitching splenorraphy technique: experimental and clinical study.

BACKGROUND: The aim of the present study was to describe the laboratory development and the subsequent clinical utility of the U-stitching technique for splenorraphy over the recent years in a general non-trauma hospital. Patients with splenectomies and patients treated conservatively during the same time period, are also presented. METHODS: In the 15-year period from September 1988 until September 2003, 65 patients were diagnosed with splenic injury following admission to 2nd Department of Surgery, Democritus University Hospital, after blunt abdominal trauma. During the first 3 years, 14 patients were admitted; one of them was treated conservatively and 13 had splenectomies. Because computed tomography (CT) was not available at that time, these 14 patients form a control group. During the remaining 12-year period, 51 patients (39 male and 12 female; age, 4-82 years; mean, 31.1 years; SD, 19.7 years) were treated conservatively or surgically, either with splenectomy or with splenorraphy. Splenorraphy was performed using the U-stitching technique. This alternative splenorraphy technique was first tested on experimental models at 2nd Department of Surgery, Democritus University Hospital, then followed by successful clinical application. The medical records for these patients were reviewed to extract the data for the present study. RESULTS: Thirty-six patients (70.6% of 51 patients) were treated surgically; of these, 21 (41.2% of 51 patients) had splenectomy and 15 (29.4% of 51 patients) had splenorraphy. Non-operative treatment was initially given to 15 patients (29.4% of 51 patients). Two of them had delayed rupture of the spleen and underwent splenectomy (at 8 and 40 days). The total number of preserved spleens was 28 of 51 (54.9%). None of the patients with conservative treatment or splenorraphy died. One patient with splenectomy died later from overwhelming sepsis. CONCLUSIONS: Splenic salvage is now a treatment goal. If the patient is haemodynamically unstable and splenorraphy is possible, the U-stitching technique is a promising approach.
