PURPOSE: The early surgical outcomes of endoscopic thyroidectomy in papillary thyroid cancer (PTC) are comparable to those of conventional open thyroidectomy; however, there is little evidence about long-term outcomes. The aim of this study was to compare the 5-year surgical outcomes of endoscopic versus open thyroidectomy. METHODS: We reviewed 804 patients with PTC who underwent thyroidectomy between October 2008 and October 2010. Of these, 703 patients received conventional open thyroidectomy (OT group) and 101patients underwent endoscopic thyroidectomy (ET group). The clinicopathologic characteristics and surgical outcomes were compared between those treatments. RESULTS: ET was applied significantly more often in young patients and females. The lobectomy and unilateral CCND were performed more frequently in ET, and the mean tumor size was smaller. The prevalence of extrathyroidal extension, multiplicity, and lymphatic invasion was more frequent in OT. The T and TNM stage were more advanced in OT, whereas the N status was similar between treatments. The mean surgical time was significantly longer for ET, while the number of retrieved lymph nodes was greater in OT. However, the stimulated thyroglobulin levels at first RAI ablation, total amount of RAI administration and 5-year recurrence rate did not significantly differ between groups. The incidence of transient hypocalcemia was significantly higher in OT, but the incidence of permanent hypocalcemia and transient/permanent recurrent laryngeal nerve injury were similar in both groups. CONCLUSION: Endoscopic thyroidectomy might be a safe and effective procedure in well-selected PTC patients

Primary adenosquamous carcinoma of the liver is a very rare type of cholangiocarcinoma and is defined as a cancer containing both squamous and adenomatous components in the same lesion. Recently, we experienced a primary adenosquamous carcinoma of the liver presented as liver abscess. A 63-year-old man was presented with a 4-day history of fever and chill. The radiologic study showed a 4 cm-sized, central hypoattenuated mass with peripheral rim enhancement in the left lobe of the liver. Ultrasonography-guided aspiration and biopsy suggested an adenocarcinoma with abscess in the liver. At laparotomy, the tumor occupied the left lobe of the liver and invaded the right diaphragm. An extended left lobectomy and a partial excision of the involved diaphragm were done. Grossly, the tumor was 6x5x5 cm in size and had an eccentric necrosis. Microscopically, the tumor was composed of adenocarcinoma and squamous cell carcinoma with a transitional area.

Peritonitis remains the leading cause of the patient dropout in CAPD in many developing countries. In Korea, 71% of CAPD patients dropout is caused by peritonitis. To elucidate an adequate guideline for treating peritonitis in our country, we analyzed clinical and bacteriologic profiles of peritonitis(1995. 1. 1- 1999. 12. 31). Two hundred and twenty eight episodes of peritonitis were developed in 127/247 patients. The incidence of peritonitis was 0.41/patient-year in general, which was decreased to 0.24/patient-year in 1999. The incidence of causative organisms were as follows; 82(36.0%) by Gram positive organisms, 38 (16.2%) by gram negative organisms, 16 cases(7.0%) by mixed organsisms, and 5 cases(2.2%) by fungus. During study period, the incidence of peritonitis by gram positive organsism was decreased while the incidence of peritonitis by gram negative organism was not changed. Recurrent infection/relapse was noted in 58 patients(45%). Peritonitis were eradicated only in 66% of the cases by initial antibiotics(cefazolin+aminoglycoside); and another 17% responded by second line antibiotics. Peritoneal catheters were removed in 38 episodes(16.7%). Patients with exit infection were more frequent in removal of catheter. Risk factor analysis was performed in 146 patients, who were newly started CAPD. There were 60 initial episodes of peritonitis(mean duration of follow up was 16.7 patient months). Sixty-five percent were free of peritonitis at the end of first year, 54% at the end of second year and 45% at the end of third year (Kaplan-Meier). Factors such as age, sex, underlying DM, were not risk factor for CAPD peritonitis. In conclusion, we observed that the incidence of peritonitis decreased every year. It was revealed however that only 66% of peritonitis can be successfully treated by first line antibiotics. Second line antibiotics such as ceftazidime may need to be introduced in early phase of CAPD peritonitis. Up to one third of patients had recurrent infection/relapse, which raised the incidence of peritonitis. Continuing education as well as better exit care is needed to improve technical survival of CAPD patients in Korea.
