Pelvic actinomycosis is a rare chronic anaerobic infectious disease, which occurs most commonly in association with an IUD. It is difficult to diagnose the disease initially. In most cases, the diagnosis is made postoperatively because of its diverse clin

We have experienced a case of occult papillary thyroid carcinoma presenting as an anterior mediastinal mass in a 40-year-old man. The CT scan revealed a huge mass behind the manubrium of the sternum but the ultrasound examination failed to detect any lesion and developmental defect in the thyroid. Excision of the mediastinal mass and total thyroidectomy were carried out. Histologically, the mediastinal mass turned out to be papillary carcinoma without any portion of the normal thyroid tissue or normal lymph node tissue and the thyroid gland showed a tiny papillary carcinoma with the diameter of 0.3cm. Although a mediastinal mass as the sole presentation of the thyroid carcinoma is very rare, we suggest that a mediastinal mass should be added to the list of possible metastatic thyroid carcinoma.

Robotic surgery is an emerging technology. After adoption of robotic surgery for cholecystectomy in 1997, various general surgical procedures have been performed using surgical robot. In general surgery, robotic surgery is applied to wide range of procedures, however, it is still in its early years. Cholecystectomy, Nissen fundoplication, Heller myotomy, and Roux-en-Y gastric bypass are the most frequently performed robotic operations. Most reports proved that application of robotic technology for general surgery is technically feasible and safe with the help of improved dexterity, better visualization, and high level of precision. However, still the absence of tactile sense and extremely high costs are the problems to be solved. Although robotic surgery has demonstrated some clear benefits compared to conventional surgeries including laparoscopy, it remains to be seen whether these benefits will outweigh the associated disadvantages or problems of robot surgery. Therefore, more prospective randomized study comparing the shot-term and long-term surgical outcomes between robotic and conventional laparoscopic surgery is needed to further define the impact of robotic surgical technology in general surgery.

특발성 양수과다증 및 양수과소증이 주산기 예후에 미치는 영향

Objective: Ultrasound estimation of amniotic fluid volume (AFI) is a critical component of antenatal surveillance. Alterations in AFI have classically been considered an indication of fetal compromise. Thus, this study was undertaken to determine whether there is any association between idiopathic polyhydramnios or oligohydramnios and adverse perinatal outcome. Methods: Women delivered between December 1999 and November 2005, and who underwent ultrasonography from 26 to 41 weeks gestation were analyzed. Twenty-seven consecutive women with singleton pregnancies complicated by idiopathic polyhydramnios (amniotic fluid index>25) and 31 women complicated by oligohydraminos (amniotic fluid index<5) were included in this study. We reviewed the perinatal outcomes including preterm delivery, birth weight, primary cesarean section rate and indication, Apgar score (1-min and 5-min), and admission to NICU (neonatal intensive care unit). These findings were compared with those of 50 matched control patients with normal amniotic fluid volume. Results: We observed that idiopathic oligohydramnios was significantly associated with primary perinatal outcome (Cesarean delivery for fetal distress) as well as secondary outcome variables such as birthweight, SGA (small for gestational age), Apgar score<7 at 1-min, 5-min, and NICU admission rates. On the other hand, idiopathic polyhydramnios did not correlate with any other perinatal outcome, except for rates of LGA (large for gestational age). Conclusion: The present study suggests that AFI is a weak predictor of perinatal outcome than has been classically suggested. But we demonstrated that the AFI identification of polyhydramnios was helpful in identifying LGA, and idiopathic oligohydramnios was a significant predictor of poor perinatal outcome.

Purpose: Even with excellent surgical outcome, recurrence of early gastric cancer (EGC) after a curative resection is not declining because the incidence of EGC is increasing. The aim of this study was to propose an appropriate treatment strategy by assessing the risk factors for recurrence of curatively resected early gastric cancer. Materials and Methods: Of 3662 patients who had undergone gastric resections for gastric cancer from 1987 to 1996, the cases of 1050 curatively resected EGC patients were reviewed retrospectively. Among those 1050 patients, 50 patients ($4.8\%$) were diagnosed as having recurrent cancer, which was confirmed by clinico-radiological examination or re-operation. The risk factors that determined the recurrence patterns were investigated by using univariate and multivariate analyses. Results: The mean time to recurrence was 30.9 months, and hematogenous recurrence was the most frequent type ($32.0\%$). Among the 50 recurred patients, peritoneal recurrence showed the shortest mean time to recurrence ($18.5\pm17.7$months). Between the recurred and the non-recurred patients, there was no statistically significant difference with respect to age, sex, operation type, tumor size, tumor location, gross appearance, or histological differentiation. However, depth of invasion (submucosal invasion) and nodal involvement were significantly different (P<0.001) between the two groups. Using logistic regression analyses, nodal involvement was the only significant risk factor for recurrence in early gastric cancer (P<0.001). The median survival after the recurrence had been diagnosed was 4 months. Conclusion: Although the prognosis for EGC patients is excellent and recurrence of EGC after a curative resection is rare, the time to recurrence and the patterns of recurrence in EGC patients were diverse and unpredictable, and the result after recurrence is dismal. Considering the impact of lymph node metastasis on recurrence of EGC, a systematic lymphadenectomy, rather than limited surgery, should be performed if lymph node involvement is confirmed pre- or intraoperatively. Also if the postoperative pathologic findings reveal lymph node involvement, adjuvant chemotherapy is recommended.

위암 환자에서 감시 림프절 및 고립 림프절 전이에 근거한 최소 림프절 절제에 대한 재고

Purpose: The incidence of nodal metastases is as low as 2 to $20\%$ in early gastric cancer, so there is a trend to lessen the extent of surgery. In addition, the adequate range for a lymphadenectomy is controversial, especially in early gastric cancer. In this study, we tried to find the minimal range for a lymphadenectomy by analyzing sentinel-node and solitary lymph-node metastases in gastric cancer. Materials and Methods: The total of 78 patients who underwent a curative gastrectomy with a D2 lymphadenectomy for early gastric cancer between 2000 and 2002 in the Department of Surgery, Yonsei University, Seoul, Korea, were included for the evaluation of sentinel-node metastases.. After a laparotomy, 25 mg of indocyanine green was mixed in 5 ml of normal saline, and all the dye was injected into the subserosal layer around the primary tumor. All nodes stained within 5 minutes were marked. In addition, a total of 141 patients, who underwent a curative gastrectomy between 1997 and 2001 at the Department of Surgery, Yonsei University, Seoul, Korea, were analyzed for solitary lymph- node metastases. Results: Among the 78 patients, sentinel nodes were detected in 69 patients ($88.5\%$). The sentinel nodes in 60 cases ($87.0\%$) were located in the perigastric area. However, 9 cases ($13.0\%$) had sentinel nodes in the N2 group. In the 141 cases that had a solitary metastatic node, 125 cases ($88.6\%$) demonstrated the metastatic lymph node in the perigastric area, and 16 cases ($11.4\%$) showed that the metastatic node in the N2 group. Conclusion: Taken together, removal of a perigastric lymph node could miss early metastases in gastric cancer, so a D1 lymphadenectomy should not be the minimal range of dissection if a lymphadenectomy is necessary.
