סרטן הערמונית הוא השאת השכיחה ביותר בגברים מבוגרים. הטיפול בלוקים במחלה מוקדית המוגבלת לבלוטה הוא בניתוח או בהקרנות. בעשור האחרון הוכנסה שיטת הטיפול בקרינה מייננת פנימית – ברכיתרפיה באמצעות גרגירי יוד רדיואקטיביים. אנו מדווחים במאמר זה על 150 חולים ראשונים שטופלו בברכיתרפיה והיו במעקב שנע בין 3-24 חודשים (חציון 15 חודש). בעשרים מהחולים שולבה גם קרינה חיצונית, בהתאם למדדי קבלה מקובלים.

במעקב שנערך ב-89% מהחולים נצפו ערכי PSA נמוכים מ-0.5 נאנוג'/מ"ל, כעדות להחלמה. רק ב-6 חולים נצפתה עלייה מתונה בערכי PSA – כעדות להישנות המחלה או לאי-החלמה ממנה.

התחלואה היתה בינונית, והתבטאה בהפרעות בהטלת שתן כתוצה מחסימה ובגירוי (irritability), שנמשכו כ-3 חודשים בממוצע. לאחר תקופה זו, ערכי ה-IPSS – ניקוד לתסמינים של מוצא השלפוחית – חזרו לערכים טרם הטיפול.

שליש מהחולים התלוננו על אין-אונות, שהופיעה רק לאחר הטיפול. הערכים נמדדו באמצעות שאלון למילוי עצמי (IIEF). החולים לא לקו בסיבוכים קשים, ולכן לא היו זקוקים לניתוח, אישפוז או צנתור ממושכים, ולא הובחנו נזקי קרינה באזור החלחולת.

לסיכום, במאמר זה מדווח לראשונה בישראל על שיטת הטיפול בברכיתרפיה באמצעות יוד-125 בלוקים בסרטן הערמונית. תוצאותיה לטווח קצר ולטווח בינוני מצויות במתאם עם הדיווחים בספרות, ופגיעתה באוחר-החיים של החולה היא מיקטית (minimal), דהיינו הפגיעה בהרגלי ההשתנה והזיקפה של החולים היא נמוכה (רק בשליש מהחולים) ובהשוואה להשפעות-הלוואי והסיבוכים המדווחים בטיפולים חלופיים, כגון ניתוח רדיקלי או קרינה חיצונית.

Introduction: Sentinel lymph node biopsy (SLNB) has been recently proven to be an accurate staging method for breast cancer, replacing axillary lymph node dissection (ALND) in selected cases. We present our initial experience and the process of introduction and implementation of SLNB in a University Hospital setting.

Material and methods: 46 SLNB were performed in 42 consecutive female patients with invasive breast cancer. Treatment included 0.4mCi-2mCi of Tc-99m rhenium colloid injected either 2 hours before surgery (0.4 mCi) or the night before surgery (2 mCi). Four milliliters of Patent Blue V were injected peritumoral 10 minutes prior to skin incision in all patients. Following SLNB all women underwent subsequent ALND. Sentinel nodes were processed both with multiple (10-15) H&E sections and immunohistochemistry with cytokeratin antibodies stain.

Results: Blue dye, isotope or the combination of both identified 43/46 (93%) of the sentinel lymph nodes. ALND was performed only unilaterally in 4 patients with bilateral breast cancer bringing the total evaluable SLNB to 39. In the 39 patients in whom the sentinel node was successfully identified and underwent ALND, the SLNB was true positive (TP) in 17/39 (44%) true negative (TN) in 20/39 (51%) and false negative in 2/39 [(5%), both T2 lesions] with overall accuracy of 95%. In the last 10 cases all sentinel nodes were successfully identified with 70% TP and 30% TN.

Conclusions: Experience with at least 30-40 consecutive cases for safe implementation of SLNB in clinical practice. Specific training and dedication is required for the entire team involved, including surgeons, nuclear medicine physicians and technicians and pathologists.

Prostatic cancer (PC) is second only to lung cancer as a cause of cancer mortality in men word-wide. In Israel it is the most common cause of cancer mortality in men, after lung cancer and colo-rectal cancer.

We screened, for the first time in Israel, for prostatic cancer using serum levels of PSA and a digital rectal examination (DRE). The purpose was not only to diagnose PC but also to increase public awareness of the condition.

300 men in the Haifa area who met statistical criteria for early diagnosis of PC participated. They filled a questionnaire regarding risk factors for PC (age, family history (FH) of prostatic and breast cancer, cigarette smoking, alcohol consumption, previous PSA sampling) and were examined. Those who had out-of-ragne, age-related PSA values, or a pathologic DRE underwent trans-rectal ultrasound (TRUS) examination and guided biopsy of the prostate. Those with a positive biopsy for PC underwent radical prostatectomy or radiation therapy.

41 (14.3%) had out-of-range, age-related PSA levels and 10 (3.5%) had a pathologic DRE. 39 (13.3%) underwent TRUS and biopsy and 6 (2.04%) had clinically significant PC, all early stages (Gleason 4-6).

Correlation between age and PSA has been proven statistically significant (p<0.05). Symptoms of urinary tract obstruction and nocturia were related to a high PSA (p=0.035 and 0.002, respectively). Those with PC had at least 1 symptom of urinary tract obstruction; 6 (15.3%) who underwent TRUS and biopsy and a FH of prostate cancer. However, no subject with a FH of PC had biopsy-proven cancer. Those with PC had PSA values from 4.9 to 31.8 ng/ml (9.6 median). Age-related PSA had a positive predictive value of 17.1%.

Results of our annual screening for early detection of PC using age-related PSA, and DRE are encouraging: cases detected were clinically significant and treatable. It would appear that screening for PC will result in decreasing the incidence of metastatic cancer and therefore mortality. 
 

Histoacryl Vs Dermabond Cyano- Acrylate Glue for Closing Small Operative Wounds

Dept. of Pediatric Surgery, Bnai-Zion Medical Center and Bruce Rappaport Faculty of Medicine, Technion - Israel Institute of Technology, Haifa

Acrylate glues used in a childrens' day care unit to close small surgical wounds were compared. In 157 children, aged 12 weeks to 3.7 years, either Histoacryl or Dermabond was used (respectively, H: Ethicon Inc., Johnson & Johnson, NJ or D: Dermabond, Braun Surgical Gmbh, Melsungen, Germany). Operations were for inguinal hernia (110 cases), hydrocele (25), undescended testis (16), umbilical hernia (13) and funiculocele (3).

1 week after surgery the wounds were evaluated in terms of integrity of closure, redness or infection, need for antibiotics, wound granuloma, and parental satisfaction with instructions and actual method of wound caring. 3 months after surgery the wound/scar was reexamined.

The margins of the wounds were separated partially or completely in 8 of 85 in group H (9.4%) while in the D group, 2 wounds (2.4%) had partially opened (p<0.05). There were no differences between the glues with regard to wound infection or cosmetic results. Parental satisfaction was higher with D (96%) than H (82%) but the difference was not statistically significant.

It is convenient to use glue to close operative wounds in children after ambulatory surgery. The use of D significantly reduced wound ruptures compared to H. Long-term cosmetic results were similar.

There are more than 200 procedures for repairing stress urinary incontinence. We evaluated the safety and efficiency of the Burch laparoscopic procedure in 32 women with urodynamically proven genuine stress incontinence.

Mean operating time was 40 minutes and mean hospitalization time after the procedure was 30 hours. The cure rate was 97%, similar to that rin other studies (80-95%). The major complications w2 cases (6.2%) of unintended bladder injury, diagnosed and repaired laparoscopically. Although follow-up has only been for 3-42 months, the high cure rate and safety and advantages of laparoscopy over laparotomy, make laparoscopic Burch colposuspension the procedure of choice for repairing stress incontinence.

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.

Osteoarthritis results from progressive catabolic loss of cartilage proteoglycans due to imbalance between synthesis and degradation. The availability of glucosamine, an intermediate in mucopolysaccharide synthesis, can be rate-limiting for proteoglycan production in cartilage tissue culture.

57 patients suffering from osteoarthritis of the knee were randomized into a group treated for 4 weeks with daily IV glucosamine sulfate (GS) together with 800 mg chondroitin sulfate, and a placebo group. Knee pain at rest, on movement and on palpation, as well as range of knee motion were then recorded.

In the GS group, there was significant reduction of clinical symptoms (p<0.01), but no significant reduction in the placebo group. Physicians' assessment of tenderness and range of motion were significantly in favor of the GS group (p<0.01). In those treated with glycosamine there were no adverse reactions and no changes in laboratory blood tests.

A recent further development in laparoscopic surgery is microlaparoscoopy. The technique is identical to standard 10 mm laparoscopy except for the use of small, 2 mm scopes and trocars. We used this technique in 19 patients treated from June 1998 to February 1999.

The advantages of microlaparoscopy are: smaller incisions, less risk of damage to pelvic organs and less postoperative pain. However, the use of microlaparoscopy for operative procedures is limited to simple operations due to the limited field of vision. We urge our colleagues to consider microlaparoscopy whenever diagnostic laparoscopy is needed.

Pancreatic lesions present a diagnostic challenge. Even modern imaging techniques are not sensitive enough in determining resectability of pancreatic tumors. A substantial proportion of patients therefore undergo unnecessary surgical exploration. We determined the impact of laparoscopy and laparoscopic ultrasound (LAPUS) examinations on surgical decision-making in 60 patients with pancreatic lesions.

Of 48 with solid pancreatic lesions, 22 were defined by LAPUS as having nonresectable tumors, while conventional imaging studies defined only 9 of them as such. 3 of these 9 underwent successful resections of the pancreatic mass. Surgical intervention was ruled out by LAPUS in 16 patients (33.3%) but 26 had resectable lesions of whom 25 underwent surgery. 3 of this group were found to have nonresectable tumors at surgery, a false-positive rate of 6.2%. Overall sensitivity of LAPUS in our series was 88%.

In 12 patients with cystic pancreatic lesions LAPUS contributed significantly to the preoperative decision due to clear imaging of the cystic lesion. Additional information was obtained from ultrasound guided-biopsy of the cyst wall, as well as determination of tumor-marker levels in the cystic fluid aspirate. LAPUS contributed significantly to operative management in 58%.

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.

We describe our experience in 54 consecutive patients who underwent laparoscopic repair of 86 inguinal hernias. Laparoscopic repair of inguinal hernia is technically feasible, does not prolong the length of the procedure nor of hospitalization and is not accompanied by increased morbidity. Although there is not yet general agreement, in our experience and that of others, it appears that laparoscopic repair will be the preferred approach to the treatment of inguinal hernia.

Discontinuation of long-term, low-dose aspirin prior to ambulatory oral surgical procedures was assessed in a blind, controlled prospective study. 50 patients on low-dose aspirin who needed dental extractions, periodontal surgery, or other ambulatory oral surgery were randomly divided into test and control groups. The control patients stopped taking aspirin a week before operation, but in the test group aspirin was continued. Before, during and after surgery bleeding time was tested. Although bleeding time was significantly longer when aspirin was continued, in both groups it was within normal limits. Intraoperative hemorrhage was more frequent in those taking aspirin. Hemostasis control posed no problem and there were no postoperative complications in either group. It is concluded that discontinuing low-dose aspirin prior to elective oral surgery is not justified.

The effectiveness of transurethral microwave thermotherapy (TUMT) for benign prostatic hypertrophy in poor surgical risk patients (ASA class IV) with indwelling catheters, was assessed. All had had an indwelling catheter for 1-12 months. Removal of the catheter was possible in 14 out of the 24 (58.3%). Urinary peak flow rates were 12.2±3.5 ml/sec at 3 months of follow-up and post-voiding residual urine volumes of less than 50 ml were recorded in 13 catheter-free patients. Our data suggest that TUMT is an effective procedure for management of high risk patients with indwelling catheters in whom surgery or anesthesia are contraindicated.

112 patients with localized prostate cancer, clinical stage A2-C, were treated by definitive radiotherapy between 1982-1988. Radiation volume encompassed the prostate, seminal vesicles and pelvic lymph nodes. The 10-year actuarial survival figures were: overall 51%; stage A2 87%; stage B 50%; stage C 36%; well differential tumors 67%; moderately differentiated 50%; poorly differentiated 32%; patients with local tumor control 55%; and patients with minimal local control 36%. It is concluded that external beam irradiation is effective in localized prostatic cancer. Stage and grade are prognosticators of survival.
