Purpose: Operative morbidity and mortality from gastric cancer have decreased in recent years, but many studies have demonstrated that its prevalence is still high. Therefore, we investigated the risk factors for morbidity and mortality considering the type of complication in patients with gastric cancer. Materials and Methods: A total of 259 gastrectomies between 2004 and 2008 were retrospectively reviewed. Results: Overall morbidity and mortality rates were 26.6% and 1.9%, respectively. A major risk factor for morbidity was combined resection (especially more than two organs) (P=0.005). The risk factors for major complications in which a re-operation or intervention were required were type of gastrectomy, upper location of lesion, combined resection, and respiratory comorbidity (P=0.042, P=0.002, P=0.031). Mortality was associated with preexisting neurologic disease such as cerebral stroke (P=0.016). In the analysis of differen complication's risk factors, a wound complication was not associated with any risk factor, but combined resection was associated with bleeding (P=0.007). Combined resection was an independent risk factor for a major complication, surgical complication, and anastomotic leakage (P=0.01, P=0.003, P=0.011, respectively). Palliative resection was an independent risk factor for major complications and a previous surgery for malignant disease was significantly related to anastomosis site leakage (P=0.033, P=0.007, respectively). Conclusions: The risk factors for gastrectomy complications of gastric cancer were combined resection, palliative resection, and a previous surgery for a malignant disease. To decrease post-gastrectomy complications, we should make an effort to minimize the range of combined resection, if a palliative gastrectomy is needed for advanced gastric cancer.

In hepatoblastoma, encouraging cure rates have been achieved with recent advances in chemotherapy and surgical techniques, The aim of this study is to evaluate the role of combined therapeutic modalities and surgical resection in hepatoblastoma. Fifteen cases of hepatoblastoma were treated from January 1993 to August 2000. Six patients had resectable tumors at initial diagnosis. All underwent surgical resection and in four patients postoperative adjuvant chemotherapy was needed. Nine out of 15 patients had unresectbale tumors at initial diagnosis, and preoperative chemotherapy was applied. There was one operative mortality and 14 patients showed good prognosis after surgery. Although various treatment modalities should be combined for the unresectable hepatoblastoma. surgical resection remains the major curative procedure.

Between June 1988 and June 1994, twenty five patients with locAlly advanced esophageal carcinoma received preoperative chemotherapy (Cisplatln, 5-Fluorouracil with or without Etoposide) and followed by resection. All patients had clinical evidence of airway involvement or distant Iymphnode involve- ment (M 1 Iymphnode) on bronchoscopy or computed tomographic scans. The major response rate to chemotherapy decided by the postoperative stage was 48% (12125). The resection rate was 92% (23/25) with overall complete resection rate of 72% (18125). Two patients had exploratory laparotomy (thorn- cotomy) only. Thirteen patients had esophagogastrostomy with a combined abdominl and Rt. thoracic approach (Ivor Lewis operation), slx pAtients had transhiatal esophagectomy, four patients had esophagogastrostomy with a combined Rt. thoracotonly & abdominal, cervical approach. There were three postoperative deaths (12%). Follow-up duration was between 3.3 months to 65 months. Median survival ime of resected patients except hospital death was 14.8 months. Actuarial survival at 12, 24 months was 72.9%, 26.2%. Signifi- cant better survival was associated with responder group (postoperative stage less than lIB) (P=0.029). These results demonstrate that 1) Preoperative Cisplatin based combined chemotherapy Produce high response rate, 2) High complete resection rate with acceptable mortality rate occur after preoperative chemotherapy, 3) Better surviL dl can be anticipated if complete resection performed after major re- sponse to preoperative chemotherapy.

Purpose: In the UICC staging system, stage IV contains not only those patients with distant metastasis but also patients with far advanced T and N status but without distant metastasis. We investigated the prognostic factors of stage IV gastric carcinoma patients without distant metastasis after curative resection. Materials and Methods: 190 stage IV gastric carcinoma patients without distant metastasis were reviewed after curative resection. Results: Male sex, distal third location, Borrmann type III, IV and histologically undifferentiated type were common. 5 year survival rate of the 190 patients was $22.2\%$. Depth of invasion and lymph node metastasis did not influence survival. The lymph node ratio (positive lymph node / retrieved lymph node) and combined resection affected survival by univariate and multivariate analysis. Conclusion: Combined resection and positive lymph node ratio were the independent prognostic factors in the patients with stage IV gastric carcinoma who underwent curative resection.

Aim: To compare drainage alone or combined with anti-tumor therapy for treatment of obstructive jaundice caused by recurrence and metastasis after primary tumor resection. Materials and Methods: We collect 42 patients with obstructive jaundice caused by recurrence and metastasis after tumor resection from January 2008 - August 2012, for which percutaneous transhepatic catheter drainage (pTCD)/percutaneous transhepatic biliary stenting (pTBS) were performed. In 25 patients drainage was combined with anti-tumor treatment, antineoplastic therapy including intra/postprodure local treatment and postoperative systemic chemotherapy, the other 17 undergoing drainage only. We assessed the two kinds of treatment with regard to patient prognosis. Results: Both treatments demonstrated good effects in reducing bilirubin levels in the short term and promoting liver function. The time to reobstruction was 125 days in the combined group and 89 days in the drainage only group; the mean survival times were 185 and 128 days, the differences being significant. Conclusions: Interventional drainage in the treatment of the obstructive jaundice caused by recurrence and metastasis after tumor resection can decrease bilirubin level quickly in a short term and promote the liver function recovery. Combined treatment prolongs the survival time and period before reobstruction as compared to drainage only.

목적: 주위 장기를 침범한 진행성 위암에서 병소의 완전한 절제를 위해서는 침범된 장기의 합병 절제가 필수적이다. 그러나 종양이 췌장 두부나 십이지장물 침범하는 경우에는 낮은 절제 성공과 높은 이환율로 인하여 병소의 완전한 절제는 제한된다. 이에 저자들은 췌장 두부 또는 십이지장을 침범한 위암에서 시행된 수술 방법을 후향적으로 분석하여 수술 방법 선정의 적절성을 알아보고가 하였다. 대상 및 방법: 1998년 1월부터 2003년 12월까지 5년가 예수병원 외과에서 위선암으로 진단되어 수술을 시행한 환자 중 수술 소견상 원발 종양이나 구역 림프절에 의해 췌장 두부나 십이지장의 침범이 의심되는 45명의 환자 중 비치유 인자를 동반하지 않은 22예를 대상으로 후향적 연구를 시행하였다. 합병 절제를 시행한 4예를 PD군, 위아전절제술만을 시행한 12예를 STG군, 고식적 우회술만을 시행한 6예를 GJ군으로 분류하였다. 각 군에서 임상병리학적 특성 및 수술적 자료를 비교 분석하였다. 결과: PD군은 모두 D3 림프절 절제술을 포함하는 췌십이지장절제술을 시행하여 병소의 완전한 절제를 하였으며, 1예에서 췌장루를 보였고(이환율 25%) 수술로 인할 사망 예는 없었다(사망률 0%), PD군은 모두 제 IV 병기였으나 75%의 2년 생존율과 50%의 5년 생존율을 보였다. STG군은 종양을 변연 절제(marginal resection)하거나 (6예) 고식적 절제술을 시행하였으며(6예) 림프절 절제의 범위도 D2 이하로 적었고 41.7%의 2년 생존율과 16,7%의 5년 생존율 보였다. GJ군은 평균 연령이 $72.7{\pm}8.6$세로 고랑이었으며 2년 생존율이 0%였다. 결론: 췌장 두부를 침범한 진행성 위선암에서 합병 절제로서의 췌십이지장절제는 중등도 이환율과 낮은 사망률로 비교적 안전하게 시행될 수 있고 비치유 인자가 없는 경우 장기 생존을 기대할 수 있는 술식으로 생각된다.

A variety of reduction labiaplasty techniques have been introduced to date, but no single technique will offer the optimal solution for every patient. Rather, the technique should be chosen based on anatomical, configurational, and technical considerations, as well as on patients' personal preferences regarded maintenance of the labial rim, maintenance of labial sensitivity, and prevention of iatrogenic thickening of the labium. We reviewed, defined, and assessed labial configurational variety, neurovascular supply, reduction techniques, and patient's preferences as the considerations relevant to the choice of labiaplasty technique. Based on this review, an algorithm was constructed that leads to a choice of reduction technique through five decisions to be made regarding (1) resection or (partial) retention of the labial free rim, (2) the measure of required labial width reduction, (3) labial vascular status, (4) prevention of iatrogenic labial thickening, and (5) preservation of labial sensibility. The choice of techniques includes edge trimming, central spindle form de-epithelialization or full-thickness resection, and three modifications of the wedge resection or de-epithelialization technique. These three modifications comprised a modified anterior resection or de-epithelialization combined with posterior flap transposition, a custom flask resection or de-epithelialization, and a modified posterior wedge resection or de-epithelialization combined with anterior flap transposition. Use of the five decisional steps and the inclusion of modifications of all three conventional reduction techniques offer an improved algorithm for the choice of labioplasty technique.

It has been widely accepted that complete surgical resection of hepatoblastoma is essential for long-term survival. But unfortunately less than 50 % of hepatic tumors in children can be totally removed at the time of diagnosis. This report is to present the experience of successful resection of hepatoblastoma after concurrent radiotherapy with transarterial chemoinfusion in a child. We believe this modality of treatment enables complete resection of unresectable hepatoblastoma. which is resistant to the systemic chemotherapy.

From Jan.1982 to Dec.1990, 77 patients with rectal cancer were treated with curative surgical resection followed by postoperative adjuvant irradiation alone or combined with chemotherapy at the Department of Radiation Oncology, Korea University Hospital (KUH). Fifty-four (54/77, $70.1{\%}$) patients underwent abdominoperineal resection , 20 (20/77, $26{\%}$) patients underwent low anterior resection, and 3 (3/77, $3.9{\%}$,) patients had wide excision only. Thirty-nine (39/77, $50.5{\%}$) received sequential chemotherapy (2 cycles to 12 cycles). The 5-year survival rate for the entire group was $43{\%}:\;78.2{\%}$ in B2+B3, $39.4{\%}$ in stage C1+C2+C3. Survival rates decreased with increasing penetration of the bowel wall by tumor and the presence of regional lymph node metastasis. Those patients survival who underwent an abdominoperineal resection also experienced a significant decrease in compared to low anterior resection ($23.1{\%}$ vs. $63.8{\%}$ in 5-year survival, p <0.05). Local failure occurred in 15 ($19.5{\%}$) out of the 77 patients overall, 1($5.3{\%}$) of 19 in stage B2+B3, and 14 ($24.1{\%}$,) of 58 in stage C1+C2+C3. Presacral area was most common site of local failufre (8/17, $47.1{\%}$). Distant failure occurred in 13 ($16.9{\%}$) of 77 patients. The most frequent site of distant failure was the lung followed by the liver, the bone, and the brain. Combined locoregional and distant failure occurred in 2 ($2.6{\%}$) of 77 patients. Pathological confirmation of perirectal fat and/or regional lymph node involvement resulted in a singificant decrease in survival and local control.

Purpose: Cancer arising from the external auditory canal is a rare disease. A lesion that seems harmless in someway, can be lethal when inadequately excised, the tumor may infiltrate nerves, the parotid and auditory tissues before re-invading the skin. Wide resection of the lesion surrounding the structure and reconstruction with an adequate plan is crucial for the treatment of this disease. Methods: Two patients with external auditory canal cancer were treated with muscle flaps and skin grafts. Lateral temporal bone resection (LTBR) was performed for complete resection of the cancer. The defect cavity was obliterated with highly vascularized tissue using pedicled sternocleidomastoid muscle, and temporalis muscle individually, combined with full thickness skin graft for covering the skin defect of the ear. Results: Clear resection margin was obtained, and both patients showed disease free survival during the follow up. There was no complications of hematoma, infection, flap loss, or wound problem in both patients. Both patient received radiation therapy, there was no osteoradionecrosis or any other complication related to radiation therapy. Conclusion: Utilizing pedicled muscle flaps for managing defects after wide resection of the external auditory canal cancer is an effective method for managing this difficult disease.
