קיבוע קדמי של עמוד השידרה המותני (קקעש"מ)(1) (Anterior Lumbar Interbody Spinal Fusion–ALIF) מבוצע כטיפול במצבים כמו ספונדילוליסטיזיס, מחלות ניווניות של דיסקים בעמוד-השידרה או בעקבות כישלון קיבוע אחורי של עמוד-השידרה המותני. לביצוע קקעש"מ פורסמו גישות ניתוח שונות הן דרך דופן הבטן הקדמית וחלל הצפק והן בגישה אחור-ציפקית (retro-peritoneal approach).

עניין בביצוע הליכים אלה בגישה לאפרוסקופית התעורר כבר בתחילת שנות התשעים. בעקבות זאת פותחו שיטות ניתוח מתאימות, פותח מיכשור לאפרוסקופי ייעודי ונוצר שיתוף-פעולה בין מנתחים לאפרוסקופיים ומנתחי עמוד-שידרה. פירות מאמץ זה הניבו סידרת פירסומים על כריתות לאפרוסקופיות של דיסקים בעמוד-השידרה המותני, עם או ללא קיבוע. במאמר זה מסוכם ניסיוננו ב-23 הניתוחים הלאפרוסקופיים הראשונים לקקעש"מ שביצענו בבתי-החולים של הדסה.

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.

We present our initial experience with retroperitoneoscopic lumbar sympathectomy in a series of 5 men aged 25-45 years. 3 suffered from ischemia of the lower limbs due to Buerger's disease, 1 had severe reflex sympathetic dystrophy and 1 had vasculitis with severe, non-healing lower leg ulcers.

The right retroperitoneal space was developed with a dissecting balloon-trocar introduced via a small lateral muscle- splitting flank incision. 2 additional 5 mm trocars were used for instrumentation and clipping. L2-L3 or L3-L4 ganglia were resected; mean operating time was 120 minutes. Only oral analgesics were needed for postoperative pain control and oral food intake was resumed the following morning. The procedure was successful in all and was without complications. Mean hospital stay was 2 days.

All patients reported significant relief of ischemia or dystrophic pain and/or improvement in trophic changes in the extremities. In the patient with leg ulcers, the largest was successfully covered with a skin graft. The retroperitoneoscopic approach to lumbar sympathectomy successfully combines the advantages of minimal invasive surgery and the reliability and effectiveness of well-established open sympathectomy.

Preliminary Experience with Laparoscopic Repair of Inguinal Hernias

During 1992-1996 we performed 163 laparoscopic hernia repairs in 100 men and 2 women. The mean age was 50.6; and in 61 the operation was bilateral. 66 were by transabdominal preperitoneal approach and 36 btotal extra-peritoneal approach. There were only a few minor complications and total recurrence rate was only 4.3%, partly attributable to our learning curve. Laparoscopic inguinal herniorrhaphy reduces postoperative incisional and muscular pain and causes less disruption in the postoperative period than open repair. Return to normal activity and work is faster for laparoscopic than for open repair, but operating room costs are higher (time and equipment). However, economic advantages for the national economy should be considered.

Short term results following laparoscopic Nissen fundoplication were evaluated in 31 patients with symptomatic gastroesophageal reflux. 6 were females and 26 males, and they ranged in age from 5 months to 64 years (mean: 4.9 years in 19 younger than 18 years, and 39.3 years in 12 adults). Most of the adults who complained of pain and heartburn underwent pH monitoring, endoscopy, and manometry as needed. Milk scan was the most useful diagnostic tool for the evaluation of the children, who suffered mainly from gastroesophageal-related pulmonary disease. Indications for laparoscopic operation were identical with those for conventional open Nissen fundoplication. 1 case of dysautonomia died postoperatively; the rate of complications, mostly minor, was 22.5%. 3 patients required conversion to open Nissen fundoplication due to cardiorespiratory instability secondary to pneumothorax in 2, and to esophageal perforation in the third. 5 adults developed temporary dysphagia. 3 children had only partial improvement in their pulmonary disease following the operation, while the other 15 had complete relief. The total time for the laparoscopic operation averaged 245 minutes in adults, and 228 in children. Discharge was usually on the fourth postoperative day in adults (mean: 6.0 days). Regurgitation and heartburn were cured in 10 out of 11 adults (91%). All parents of children were satisfied. Symptomatic outcomes following laparoscopic Nissen fundoplication compare favorably with those of open surgery with respect to mortality, complications, and outcome.

The appearance of focal pulmonary lesions in a patient with a nonpulmonary malignancy is worrisome. Apart from metastasis, the differential diagnosis includes benign conditions such as infectious and granulomatous diseases, enlarged lymph nodes, atelectasis, radiation pneumonitis, and bronchiolitis obliterans with organizing pneumonia (BOOP). CT-guided needle biopsy is not always diagnostic and may not be feasible in very small lesions. Since open lung biopsy is associated with considerable morbidity, many physicians tend to postpone tissue diagnosis for a few weeks and perform a biopsy only if repeat chest CT scans show increase in size or number of the lesions. This approach may lead to undesirable delay of appropriate treatment. We report video-assisted thoracoscopic lung biopsy in 7 patients with nonpulmonary malignancy who developed lung lesions following chemotherapy and/or radiation therapy. Histological examination proved metastatic lesions in only 2. There were no operative complications and recovery was rapid and smooth in all patients. Thoracoscopic lung biopsy is an effective, minimally invasive diagnostic tool that obviates the need for thoracotomy in these patients.

Is Crohn's Disease Different In The Elderly?

We reviewed the records of 22 patients hospitalized at onset or first presentation of Crohn's disease after age 50. There were 12 females and 10 males, and the mean age was 64.5 years. The most common presenting symptoms were: abdominal pain, fever, diarrhea and weight loss. The disease was located in the small bowel in 14, in the ileo-colic region in 3 and in the colon in 5. The median interval from onset of symptoms until diagnosis was 42 months. 12 (54%) underwent surgery. All 5 patients with colonic disease were operated. 6 patients underwent small bowel resections, mostly terminal ileum, while 1 had resection of both terminal ileum and left colon. The recurrence rate was 70% in the medically treated and 50% in those operated. 1 patient died after surgery for Crohn's disease (4.5%), and 3 others died of unrelated causes. Compared to younger patients, the symptomatology, clinical course, need for and response to surgery, and its complications, did not differ in these older patients, but the recurrence rate seemed to be higher.
