Purpose: Laparoscopic surgery (LS) is an alternative to colorectal cancer surgery. Little evidence supports LS for emergency reoperation after laparoscopic colorectal surgery. The aim of this study was to assess perioperative outcomes of LS as an emergency reoperation for early complications after LS for colorectal cancer. Methods: From June 2006 through December 2016, 732 consecutive patients underwent elective LS for colorectal cancer at Kyung Hee University Hospital, Seoul, Korea. Among these patients, we retrospectively reviewed data on those who received emergency laparoscopic reoperations for complications within 30 days after surgery. Variables associated with perioperative outcomes were analyzed. Results: After exclusion of 50 patients (6.8%) who needed conversion to open surgery during LS, 79 of 682 patients (11.6%) received reoperation for complications, recurrence, and other benign diseases. Among them, 22 patients underwent emergency laparoscopic reoperation for early complications. Mean age of the patients was 62 years, and most underwent low anterior resection as a primary operation (n=17, 77.3%). Anastomotic leakage was the most common reason for reoperation (n=14, 63.6%). Postoperative complication occurred in 6 patients (27.3%), but none required further surgical intervention. Patients had first bowel movements at 2.8 days after reoperation, and length of hospital stay was 17.2 days after reoperation. Conclusion: Laparoscopic reoperation showed acceptable outcomes. LS as a reoperation for complications seemed to be feasible after LS for colorectal cancer.

Presacral tumors are rare; however, once diagnosed, surgical resection is recommended even in asymptomatic patients as there is potential risk for growth or malignant transformation. Many different types of surgical approaches to resect presacral tumors have been reported including posterior, anterior, and combined abdominosacral approaches. With introduction of the minimally invasive approach, laparoscopic or robotic approaches to resect presacral tumors are reported increasingly. We report a case of successful anterior laparoscopic resection for a presacral mass that was incidentally diagnosed during management of pancreatitis.

(표1)은 남한각지측후소의 설립이후(서울은 1907년)금일까지의 최대평균 풍속표(10분간평균) 인데 구조계산에서 필요한 순간최대풍속은 서을에서 6년전 부터 측정을 시작한 실장이고 그 이전의 측정은 없었다. -순간최대풍속추상치 기록상의 10분간 평균 풍속으로 당시의 순간최대풍속을 추상하여야 하는데 이에 대한 참고통계자료로서 일본각지의 태풍 및 선풍의 각기에 대한 기록상의 최대 풍속시의 순간최대풍속과 10분간 평균풍속의 비교를 (표2)에 작성했다. -남한의 최대풍속의 지역적 분류 (표1)과 같이 해안도시에서는 풍속이 크고 내륙지방에서 적은데 일본건축학회 에서는 풍압상의 해안와 내륙지방을 해안선에서 40KMfh 경계하고 있으나 (표1)과 같은 분류로 한다면 해안선에서 30KM로 하여야한다. 이렇게 함으로서 서울과 전주가 내륙지역에 포함되게 된다.
