Ultrasonography (US)-guided procedures such as ethanol ablation, radiofrequency ablation, laser ablation, selective nerve block, and core needle biopsy have been widely applied in the diagnosis and management of thyroid and neck lesions. For a safe and effective US-guided procedure, knowledge of neck anatomy, particularly that of the nerves, vessels, and other critical structures, is essential. However, most previous reports evaluated neck anatomy based on cadavers, computed tomography, or magnetic resonance imaging rather than US. Therefore, the aim of this article was to elucidate US-based thyroidal and perithyroidal anatomy, as well as its clinical significance in the use of prevention techniques for complications during the US-guided procedures. Knowledge of these areas may be helpful for maximizing the efficacy and minimizing the complications of US-guided procedures for the thyroid and other neck lesions.

The Kallmanns syndrome is the most common form of isolated hypogonadotropic hypogonadism in which anosmia or hyposmia resulting from agenesis of hypoplasia of the olfactory lobes is associated with LHRH deficiency, This syndrome is genetically heterogeneous and can be trans-mitted as an X-linked, autosomal dominant or autosomal recessive trait. The hypogonadotropic hypogonadism results in absent or incomplete pubertal development and may be associated with anosmia or hyposmia, mid-line defect(color blindness, cleft-lip or

Chronic postoperative inguinal pain (CPIP) is a major complication after inguinal herniorrhaphy. We report the treatment of CPIP using ultrasonography-combined with nerve stimulator for injection of the genitofemoral nerve (GFN). A 59-year-old man underwent laparoscopic herniorrhaphy and presented with numbness from the inguinal region to the scrotum after operation. In the pain clinic, ultrasonography-guided GFN block and pharmacological treatments had little effect. Six month after operation, patient was referred to the Department of Physical Medicine and Rehabilitation, and ultrasonography-combined with nerve stimulator for GFN injection underwent to enhance the accuracy of neural approach. The induction of scrotal contraction and paresthesia on the GFN distribution was monitored by nerve stimulator and local anesthetic was injected. After the block, pain relief lasted for 6 months without analgesic use. Ultrasonography-combined with nerve stimulator is an effective approach to treat CPIP as it enhances precise localization and injection of small peripheral nerve like GFN.

Congenital laryngeal cleft is a rare anomaly, which can cause serious problems of airway and repeated aspiration pneumonia. It is due m failure of fusion of the posterior cricoid cartilage lamina. Dysphagia with aspiration of food is commonly seen w1h resultant bouts of pneumonia. Detection of an unsuspected minor cleft may be difficult, but the pediatrician should suspect the possibility of deft from the clinical features. This paper includes. a detailed case report of one patient with congenital laryngeal cleft and the review of literatures.

PURPOSE: We wanted to analyze the peripheral calcification patterns of thyroid tumors that were seen on ultrasound and we also wanted to evaluate the clinical usefulness of the peripheral calcifications of the thyroid tumors. MATERIALS AND METHODS: We retrospectively analyzed 21 peripheral calcifications of the thyroid tumors of 18 patients; these were histopathologically confirmed by fine needle aspiration biopsy, automated gun biopsy and surgery. The peripheral calcification patterns were categorized into three types: type 1, peripheral nodular calcification, type 2, peripheral smooth rim calcification, and type 3, peripheral irregular rim calcification. The histopathologic results obtained during surgery, fine needle aspiration or automated gun biopsy were compared. RESULTS: Of the total 21 peripheral calcifications of thyroid tumors, 5 cases showed as being type 1 (24%), 3 cases showed as being type 2 (14%) and 13 cases showed as being type 3 (62%). Of the total 21 peripheral calcifications of the thyroid tumors, 18 were histopathologically confirmed as papillary carcinoma (86%). Among the type 1 peripheral calcification patterns, 3 cases were coincidentally diagnosed as papillary carcinoma and 2 cases were follicular neoplasm on the preoperative biopsy results and on the surgical results. Two cases of type 2 peripheral calcifications (67%) and three cases of type 3 peripheral calcifications (23%) were diagnosed as benign lesions upon preoperative biopsy, but the postoperative results were papillary carcinoma. CONCLUSION: Peripheral calcifications of thyroid tumors are important feature that suggest malignancy together with the microcalcification and peripheral calcifications of the type 2 and type 3 patterns, and these lesions may be difficult to accurately diagnose with using only biopsy.

PURPOSE: The aim of this study is to assess the safety and the efficacy of laparoscopic colorectal surgery compared to those of conventional open surgery and to determine the feasibility of laparoscopic colorectal surgery based on oncologic principles. METHODS: From March 2001 to January 2002, 27 consecutive patients were assessed for the possible use of laparoscopic surgery. Thirty patients were included in the open group. Forty-seven patients were included in the laparoscopic group. The decision regarding the suitability of a patient for the procedure was made by the surgeon. RESULTS: Laparoscopic surgery was attempted on 47 patients, and in 31 patients, it was completed successfully. Patients who underwent laparoscopic surgery required a smaller dose of analgesics and had an earlier bowel passage recovery and shorter hospital stay than patients who underwent open surgery. The mean operation times for the open group, the conversion group, and the laparoscopic group were 252 min, 269 min, and 272 min respectively (P>0.05). There was no difference in the number of lymph nodes dissected nor the length of the distal margin of the resected bowel in the case of anterior resection and low anterior resection of the laparoscopic group compared to the open and the conversion groups (P>0.05). Complications in the laparoscopic surgery group were anastomosis site leakage and bowel obstruction. In the open group, wound infection, urinary retention, anastomosis site leakage and bowel obstruction were found. The morbidities of the open group, the conversion group, and the laparoscopic group were 23.3%, 37.5%, and 12.9%, respectively. One mortality was observed in the conversion group. CONCLUSIONS: In this study, there is no evidence that the laparoscopic technique is inadequate for following the cancer surgery principle, So laparoscopic colorectal surgery is a safe and feasible treatment. The overall morbidity and mortality in this study were acceptable. Sufficient lymph node dissection and distal margin of the resected bowel were accomplished with laparoscopic surgery. Further long-term follow up, however, will be necessary to confirm the value of this technique.
