The first 1,000 laparoscopic cholecystectomies performed in our department were reviewed. There was no operative mortality; conversion to open cholecystectomy was necessary in 2%. In the last 600 cases the rate of conversion had decreased to 0.5%. There was common bile duct injury in 0.3%, with the injuries identified during primary surgery. This clinical experience is consistent with previous studies, which proved that laparoscopic cholecystectomy is safe and should replace open operation as the procedure of choice.

Cholangiocarcinoma accounts for about 1% of all malignant tumors. They are difficult to diagnose because of their small size and their location. Although surgical resection is the best therapeutic approach, most patients undergo unnecessary exploratory laparotomy due to incorrect preoperative diagnosis.

We present our experience with laparoscopic ultrasound (LU) in the evaluation of cholangiocarcinoma and determination of tumor spread and vascular involvement. Of 25 patients referred for surgery, 6 were excluded following LU and were referred instead for palliative treatment. Diagnosis of the tumor was successful in 92%, and vascular involvement was diagnosed in 46%. LU should be an integral diagnostic test in the evaluation of choriocarcinoma.

Constant advances and increasing experience in laparoscopic surgery renders it applicable for adrenal surgery. The wide exposure required for open adrenal surgery makes this minimally invasive procedure an attractive and advantageous alternative.

Between 1996-1999, we performed 35 laparoscopic adrenal-ectomies in 30 patients 20-72-years old. Indications included: Conn's syndrome - 14, pheochromocytoma - 11, Cushing's syndrome - 6, nonfunctioning adenoma - 3, and metastatic sarcoma - 1.

5 underwent bilateral laparoscopic adrenalectomy. In 3 (8.5%) the procedures were converted to open operations. Overall morbidity was 13% and there was no mortality. Mean operative time was 188 minutes, but only 130 in our last 10 cases. Mean hospital stay was 4 days and they returned to normal activity an average of 2 weeks later.

According to our study and previous reports, laparoscopic adrenalectomy is feasible and safe and it may soon become the procedure of choice for adrenal tumors.

Laparoscopic adrenalectomy has recently been shown to be safe and effective for a variety of benign adrenal tumors, such as aldosterone adenoma, pheochromocytoma, nonfunctioning adenoma, Cushing's adenoma and Cushing's syndrome. Recently, laparoscopic surgeons adopted an extraperitoneal approach in which a space is created by the introduction of a trocar with an inflatable balloon tip. This technique with a minimal access procedure provides direct access to the adrenal glands without interfering with intraperitoneal organs.

Laparoscopic adrenalectomy using the extraperitoneal approach was completed in 18/20 consecutive patients. Mean operative time was 95 min (range 80-120) and median hospital stay 3 days. Blood transfusion was not required, and there were no postoperative complications.

We present our initial experience in laparoscopic nephrectomy. 6 patients were operated for a kidney donation and 2 for treatment of a benign disease. All procedures were completed successfully, with no conversion to laparotomy or intra-operative complications. Mean operating time was 210 minutes, and in the donor kidneys the mean warm-ischemic time was 165 seconds. There were 3 postoperative complications, and mean hospitalization was 3.5 days. The transplanted kidneys are all functioning.

From our initial experience, laparoscopic nephrectomy appears to be both feasible and safe. Its implementation requires a combined team with experience in donor surgery and advanced laparoscopic skills. The procedure may increase the availability of living donor kidneys, due to the smaller impact on the donor compared to conventional donor nephrectomy.

CT-guided excision of osteoid osteoma is a new surgical technique that enables accurate resection of the nidus during 1-day hospitalization. We present 5-year results in 42 patients (26 males and 16 females, mean age 18 years, range 3-46). In 40 out of 42, complaints disappeared immediately after the procedure. The recovery period was short and the return to normal activity was faster than in the open surgical approach. Complications were minimal and transient.

Laparoscopic splenectomy is effective and technically feasible for treating various hematological diseases such as idiopathic thrombocytopenic purpura (ITP), congenital sphero„cytosis, hemolytic anemia, and Hodgkin's lymphoma. An anterior approach to the vascular pedicle is usually described. However, in this approach to the splenic hilum, the dissection of the splenic artery is frequently difficult. The laparoscopic posterolateral approach involves dissection of the posterolateral attachments to the diaphragm, followed by the disection and ligation of all splenic branches near the splenic parenchyma. We used it in 9 adults and 4 children: 11 patients had ITP, 1 spherocytosis and 1 Hodgkin's lymphoma.

This procedure was completed in 13 patients, but in 2 it had to be converted to open surgery. Mean operating time was 3 hours and mean postoperative stay 3 days. Blood transfusion was not required and there were no postoperative complications.

Laparoscopic splenectomy is safe in both adults and children, and the posterolateral approach provides excellent visualization and allows control of the branches of the splenic vein and artery in the splenic hilum.

Laparoscopic cholecystectomy is considered the procedure of choice for removing symptomatic, stone-containing gallbladders. It is estimated that in 30-40% of these operations stone(s) spill into the peritoneal cavity. It was assumed that these "dropped stones" are harmless and are dissolved and absorbed spontaneously. We present a 70-year-old woman in whom such a stone, dropped during laparoscopy, led to formation of an intraperitoneal abscess.

Laparoscopic cholecystectomy is the "gold standard" in treating cholelithiasis. Stones are frequently lost in the peritoneal cavity during the procedure, but "missing stones" have been regarded as insignificant. However, there is accumulating evidence that untreated "lost" stones may cause complications even years after operation.

We present a 65-year-old woman who presented with vague complaints, anemia and an elevated ESR. CT scan showed an infiltrating process in extra-abdominal muscles compatible with sarcoma. At operation, 2.5 years after previous laparoscopic cholecystectomy, an abscess was found which contained biliary stones. Because of their small size they were not visible on CT scan. We discuss the possible ways of handling "falling stones."

Cryosurgery is an old technique which is being used for hepatic tumors as an adjuvant to hepatic resection. We recently treated 7 patients with multiple malignant liver tumors, 5 of whom had colorectal metastases, 1 carcinoid metastases, and 1 multiple hepatic lesions of hepatocellular carcinoma. 6 underwent combined liver resection and cryoablation of lesions in the remaining liver. In the 7th patient, only cryoablation was performed because hepatic resection was rejected and there was an extrahepatic metastasis. The advantages of this treatment are removal or destruction of all liver lesions found by any method, including intraoperative ultrasound examination, maximal preservation of normal liver parenchyma and that it is curative in patients inoperable by standard criteria.

Radical prostatectomy may cure most patients in whom the malignant tumor has not invaded through the prostatic capsule. Advances in surgical technique and accumulation of experience have decreased the complication rate significantly. Long-term results of surgical treatment are now better than those of other forms of treatment; hence radical prostatectomy is now recommended for men with life expectancies longer than 10 years. Between 1988 and 1995, 164 men with clinical stages T1 or T2 adenocarcinoma were admitted for radical prostatectomy. Most were not offered a nerve-sparing procedure, so as to allow wider, more complete resection. Those who wanted preservation of sexual function underwent the nerve- preserving procedure. In 6 patients operation was discontinued when metastases to the iliac lymph nodes were detected and in 1 when invasion of the pelvic wall was found. 157 underwent radical prostatectomy. Preoperative biopsy revealed a low-grade lesion (Gleason 2-4) in 19.1%, intermediate grade (Gleason 5-6) in 61.8% and high-grade (Gleason 7-9) in 19.1%; however, pathologic grading revealed that only 7.0% had grade 2-4 tumor, 60.5% grade 5-6 and 32.5% grade 7-9. Pathologic staging revealed T2 tumor in 58%, T3 in 38.8% (including microscopic invasion of the capsule or seminal vesicles); microscopic lymph node metastases were found in 3.2%. Tumor invasion through the capsule was found in only 2 of 13 treated with neoadjuvant androgen blockade, compared with 40% in those who did not receive this treatment. There was no operative mortality and only 14.7% has complications. All had urinary incontinence immediately after operation, but regained continence after an average of 4-5 months. 24 were incontinent for more than 12 months, but most of them had only mild stress incontinence. Most patients were impotent after the procedure. There was tumor recurrence, diagnosed by rise in serum PSA, in 26 during an average follow-up of 26.4 months (range 3-93). Cure rate of prostatic cancer by radical prostatectomy may be increased by improved preoperative staging methods and better patient selection; long term follow up is required for determining cure rate.
