Background: Cryosurgery is a minimally invasive treat­ment option for prostate cancer.

Objectives: To report on the first series of cryosurgical ablation for prostate cancer performed in Israel.

Methods: Cryosurgical ablation of the prostate was undertaken in 2 patients aged 53-72 diagnosed with adenocarcinoma of the prostate. The procedures were performed percutaneously and were monitored by real-time trans-rectal ultrasound. The CRYOHIT machine applying Argon gas was used with standard or ultra-thin cryoprobes. The average follow-up was 12.8 months postsurgery (range 1- 24 months).

Results: No rectal or urethral injuries occurred and all patients were discharged from hospital within 24-48 hours. The duration of suprapubic drainage was 14 days in 10 patients and prolonged in 2. Early complications included penoscrotal edema in four patients, perineal hematoma in three, hemorrhoids in two and epidydimitis in one. Long-term complications included extensive prostatic sloughing in one patient and a perineal fistula in another, both of whom required prolonged suprapubic drainage. Minimal stress incontinence was noted in two patients for the first 8 weeks after surgery. None of the patients has yet regained spontaneous potency. A prostate-specific antigen nadir of less than 0.5 ng/ml was achieved in eight patients and an undetectable PSA level below 0.1 ng/ml in five patients.

Conclusion: Cryoablation for prostate cancer is safe and feasible, and the preliminary results are encouraging. Further study is needed to elucidate the efficacy of the procedure.

Background: Ulcerative colitis begins in early childhood in 4% of cases. Medical therapy is non-specific, and as many as 70% of children will ultimately require surgery. The dynamic growth, physical and psychological changes that characterize childhood are severely compromised by the complications of ulcerative colitis and its therapy.

Objective: To review the outcome of children undergoing early surgery for ulcerative colitis at a tertiary medical center in Israel.

Methods: A retrospective review was conducted of all children operated on following failure of medical therapy for ulcerative colitis during a 5 year period.

Results: Eleven children underwent a J-pouch procedure with ileo-anal anastomosis in one to three stages. Postoperative complications included recurrent pouchitis in 5 patients, intestinal obstruction in 3, fistula with incontinence in one, stricture in one, and wound infection in 4. Follow-up revealed that most of the patients have three to four soft bowel movements daily. All currently enjoy normal physical activities and a rich social life.

Conclusions: The quality of life in children with ulcerative colitis was markedly improved following J-pouch surgery. This procedure was not associated with major complications. We recommend early surgery as an alternative to aggressive medical therapy in children with this disease.

 Background: Radiosurgery is a therapeutic technique characterized by the delivery of a single high dose of ionizing radiation from an external source to a precisely defined intracranial target. The application of radiosurgery to the treatment of acoustic neurinomas has increased substantially in the last decade. Most of the published experience pertains to the use of the gamma knife.

Objectives: To report the experience at the first Israeli Linear Accelerator Radiosurgery Unit in the management of 44 patients with acoustic neurinomas.

Methods: We analyzed the clinical records and imaging studies of all patients undergoing radiosurgery for acoustic neurinomas between 1993 and 1997, and quanitified the changes in tumor volume, hearing status, and facial and trigeminal nerve function. The contribution of radiation dose and original tumor volume upon those variables was also studied.

Results: At a mean follow-up of 32 months (range 12–60), 98% of the tumors were controlled (75% had shrunk; 23% had stable volume). The actuarial hearing preservation rate was 71%. New transient facial neuropathy developed in 24% of the patients, persisting in mild degrees in 8%. Neuropathy correlated primarily with tumor volume. Tumors with volumes 4 ml were at high risk when marginal radiation doses were 1,400 cGy. Dose reduction to a maximum of 1,400 cGy produced no neuropathies in the last 20 patients, still preserving tumor control rates.

Conclusions: Radiosurgery is an effective and cost-efficient therapeutic modality for newly diagnosed acoustic neurinomas in the elderly or medically infirm population, and for all residual or recurrent tumors after conventional surgery.
