Although acute appendicitis is one of the most common surgical diseases, very rare but serious complications can occur including retroperitoneal abscess complicated by acute appendicitis. The early diagnosis of retroperitoneal abscess is often difficult and delayed because its clinical course is often insidious and does not present with typical symptoms of acute appendicitis. We experienced a 65-year-old male patient who was diagnosed with acute appendicitis with retroperitoneal abscess. As the retroperitoneal abscess was not fully removed via emergency operation, postoperative percutaneous drainage was performed but not effective. Retroperitoneal abscess can be cured by 2nd operation with retroperitoneal approach. We report here an unusual case of retroperitoneal abscess complicated by acute appendicitis.

Purpose: Laparoscopic surgery for left-sided colon cancer is one of the most frequent procedures performed in laparoscopic colorectal surgery. In this study, we analyzed clinical and long-term oncological outcomes of left-sided colon cancer patients who underwent conventional laparoscopic surgery (CLS) and hand-assisted laparoscopic surgery (HALS). Methods: A total of 172 CLS patients and 72 HALS patients for left-sided colon cancer from July 2001 to December 2011 were included in this study. The collected data included the clinical and oncological outcomes. We analyzed overall survival and disease-free survival by tumor, node, metastasis (TNM) stage. Results: The mean age of the patients was 64 years, and male patients were predominant. The mean follow-up period was 58.1 months. The number of patients that belong in each TNM stage 0, I, II, III, and IV was as follows: 17 (7%), 47 (19.2%), 70 (28.7%), 80 (32.8%), and 30 (12.3%), respectively. Overall 5-year survival rate for TNM stage I, II, III, and IV was 87.1%, 82.8%, 82%, and 12%, respectively. Overall 5-year survival rate for CLS group and HALS group was 90.2% and 66.7%, 86.5% and 77%, 88.7% and 67.4%, and 18.9% and 0%, respectively. Disease-free 5-year survival rate for TNM stage I, II, and III was 97.7%, 90.7%, and 72.8%, respectively. Disease-free 5-year survival rate for CLS group and HALS group was 97.3% and 100%, 100% and 78.8%, and 81% and 55.1%, respectively. Conclusion: These data show the feasibility and safety of laparoscopic surgery for left-sided colon cancer in terms of long-term oncological outcomes.

Purpose: Lymph node metastasis is a stage-determining factor and the most important prognostic factor for colon cancer patients. We aimed to verify the influence of the aspects of lymph node metastatic level on the prognosis of the stage III colon cancer patients. Methods: We studied the survival rate of ninety-eight patients with stage III colon cancer who underwent an open and laparoscopic surgery at Eulji University Hospital from November 1998 to December 2009. We evaluated the survival rate and prognostic factors including the level of positive lymph node and additional factors. The level of positive lymph node was classified as either level I (pericolic and intermediate lymph node metastasis) or level II (apical lymph node metastasis). Results: The average age of the patients was 62.7 years (range, 30 to 89 years) old and the mean follow-up period was 45.9 months (range, 2 to 129 months). The comparison of the survival rates based on the level of lymph nodes shows that level I was 89.5% while level II was 41.7% (P=0.002). Multivariate analysis showed that level of positive lymph node was a significant prognostic factor. Conclusion: In this study, the level of lymph node metastasis in stage III colon cancer was significant prognostic factor. Therefore, exact evaluation and further treatment plans should be determined based on clear analysis of various aspects of the lymph nodes acquired by accurate and meticulous surgery.
