 Background: Various methods of core suture and suture material are used successfully in acute flexor tendon repair.

Objectives: To assess the current practice in acute flexor tendon repair among Israeli hand surgeons.

Methods: A five-question survey was conducted among certified hand surgeons in Israel regarding their preferred materials and method for performing acute flexor tendon repair.

Results: Forty-eight hand surgeons participated in the survey. The most widely used core suture in zone 2 (58.3%), as well as in zones 3 and 4 (62.5%), was the modified Kessler type. The most widely used suture material was nylon. All surgeons incorporated epitendinous sutures to augment their core sutures. 

Conclusions: The modified Kessler core suture technique is the most widely used technique among Israeli hand surgeons for repairing acute flexor tendon lacerations in zones 2, 3 and 4. This finding agrees with worldwide data and with emerging data attesting to the lower risk of adhesion formation and postoperative tendon ruptures with this method. The core suture technique initially popularized by the late Prof. Isidor Kessler, who headed our department during the years 1973–92, remains the most practiced acute flexor tendon repair technique among hand surgeons in Israel.

 Background: Fine-needle aspiration biopsy has been well established as a diagnostic technique for selecting patients with thyroid nodules for surgical treatment, thereby reducing the number of unnecessary surgical procedures performed in cases of non-malignant tumors.

Objectives: To evaluate the sensitivity, specificity, accuracy, and positive and negative predictive values of FNAB[1] in cases of a solitary thyroid nodule.

Methods: The preoperative FNAB results of 170 patients who underwent thyroidectomy due to a solitary thyroid nodule were compared retrospectively with the final postoperative pathologic diagnoses.

Results: In cases of a solitary thyroid nodule, FNAB had a sensitivity of 79%, specificity of 98.5%, accuracy of 87%, and positive and negative predictive values of 98.75% and 76.6% respectively. All cases of papillary carcinoma diagnosed by FNAB proved to be malignant on final histology, while 8 of 27 cases of follicular adenoma detected by preoperative FNAB were shown to be malignant on final evaluation of the surgical specimen.

Conclusions: FNAB cytology reduces the incidence of thyroidectomy since this method has excellent specificity and sensitivity and a low rate of false-negative results. It proved to be cost-effective and is recommended as the first tool in the diagnostic workup in patients with thyroid nodules.

Background: The external approach is the golden standard for sinonasal tumor removal but it is associated with several side effects, including facial scars, intracranial and extracranial complications, a long hospitalization period and high costs. Endoscopic sinus surgery enables resection of benign and selected malignant sinonasal tumors and has the advantages of no facial scars, better functional and structural preservation of the sinonasal complex, minimal trauma to surrounding tissue, a shorter hospitalization stay and lower costs.

Objectives: To evaluate the advantages and limitations of endoscopic resection of benign and malignant sinonasal tumors, their recurrence and complication rates.

Methods: The medical and radiology records of 56 patients who underwent endonasal endoscopic resection of benign and malignant sinonasal tumors between 1996 and 2003 were retrospectively reviewed. Tumors located in the center of the nose and sinuses were endoscopically resected.

Results: Six cases of malignant tumor and 50 cases of benign tumor underwent resection by ESS[1]. One of the patients with malignant tumor died, the remainder showing no evidence of disease on follow-up of 3–60 months (mean 26.8 months). Inverted papilloma was the most common benign tumor (40 patients). Seven patients (18%) had recurrence followed by endonasal resection. No major complications were recorded. Hospitalization stay was 2–7 days (mean 3.6 days).

Conclusions: Endoscopic resection of benign sinonasal tumors that are centrally located in the nose and sinuses should be considered before the external approach is used. In very carefully selected cases of malignant tumors ESS is oncologically acceptable, but more experience is needed for discerning the indications for endoscopic resection of malignant tumors. The complication rate for endoscopic resection is low, there are no facial scars, hospitalization stay is short, and costs are low.

Background: Despite advances in cancer therapy the treatment of liver tumors remains a challenge. Most patients are poor candidates for surgical resection; both chemotherapy and irradiation have a low success rate and neither is without complications. New minimally invasive techniques for ablation of unresectable tumors have gained attention as effective treatment alternatives. Among these are percutaneous ethanol injection and radiofrequency ablation; both are effective for primary liver tumors and RFA is also effective for hepatic metastases.

Objective: To report our experience with PEI and RFA in the treatment of hepatic lesions.

Methods: The study included 49 lesions in 27 patients: 23 primary lesions in 13 patients treated with PEI and 26 lesions (22 secondary and 4 primary) in 14 patients treated with RFA. PEI was performed on an outpatient basis in the ultrasound suite; RFA was done in hospitalized patients (9 in the ultrasound suite and 4 in the operating room). Patients were followed with triphasic spiral computerized tomography 1 month after treatment and every 3±6 months thereafter.

Results: Complete necrosis was achieved with PEI on the first attempt in 11 of 23 primary lesions (91.3%). In 8.7% (2/23) a second series of treatments was required. Using RFA, complete necrosis was achieved in 85% of lesions (22/26) and partial necrosis in 15% (4/26). Complications included low fever (3 patients), high fever and abscess formation (1 patient), peri-tumoral necrosis (1 patient ) and portal vein thrombosis (1 patient ).

Conclusions: Our preliminary results confirm that PEI and RFA are an effective and safe option for treating hepatic tumors in patients unfit for surgery.
