PURPOSE: To date, the benefits of central neck node dissection (CND) in patients with differentiated thyroid carcinoma (DTC) have not been clearly demonstrated and must be considered against the potential risks of the procedure. However, recent papers suggest that lymph node metastasis exerts a significant influence on survival and is associated with a higher risk of recurrence. The purpose of our study was to assess the recurrent laryngeal nerve and parathyroid risks of CND following total thyroidectomy in patients with DTC and to compare the results with those obtained in patients who underwent total thyroidectomy only. METHODS: We retrospectively analysed 143 consecutive patients with DTC (116 with papillary, 24 with follicular, and 3 with Hurthle cell carcinoma) operated on by a single experienced endocrine surgeon from January 1989 to January 1999. There were 61 total thyroidectomies with CND (Group 1) and 82 total thyroidectomies only (Group 2). Group 1 patients displayed evidence of macroscopic lymph node invasion during surgery. The definitions of the two main complications in the thyroid surgery were as follows: transient and permanent recurrent laryngeal nerve palsy (persisting hoarseness over six months after thyroidecomy), transient and permanent hypoparathyroidism (non-recovery of normal parathyroid function and calcemia below 8.0 mg/dl over six momths after thyroidectomy). RESULTS: There was no difference observed in the demographic data between the two groups. Three cases (4.9%) of transient hypocalcemia were detected in Group 1 and two cases (2.4%) in Group 2. Five cases (8.2%) of transient nerve palsy were presented in Group 1 and one case (1.2%) in Group 2. However, there was no significant statistical difference between the two groups (p=0.051). None of the patients demonstrated permanent nerve palsy. CONCLUSION: Following total thyroidectomy for DTC, CND does not increase the morbidity of parathyroid gland and recurrent laryngeal nerve. Therefore, in order to decrease the incidence of regional recurrence and avoid the risk of reoperation in the central neck area, we recommend cervical neck node dissection from the central neck compartment concomitant with total thyroidectomy when overt lymph nodes are palpated.

Primary epiploic appendagitis of the colon is a rare cause of abdominal pain and is a self-limiting disease. Double contrast barium enema showed a smooth extrinsic compression located anterolateraly to the involved colon. Ultrasonography revealed a non-compressible echogenic ovoid mass attached to the colon wall. On abdominal CT, all lesions were seen as pedunculated ovel fatty masses with surrounding streaky densities connected to the serosal surface of the adjacent colon. Follow up CT performed 13-25(mean 18) days later showed that during this intrval, the volume of the mass and extent of surrounding infiltrations had decreased.
