Rectosigmoid Junction Tumors and Large Bowel Obstruction

OBJECTIVE: The most common cause of large bowel obstruction is carcinoma. Seventy percent of the obstructing tumors are seated at or distal to splenic flexure. In this study we aimed to figure out the frequency of presenting with obstruction of rectosigmoid function tumors and report the results of follow up.
STUDY DESIGN: Between 1992-1997, sixtyseven large bowel tumor cases were admitted to our surgical clinic. From those, 19 (28.3%) were found to have ohstruction of the large bowel and included to our study. And follow up results was presented.
RESULTS: 13 cases out of 19 (63%) were having tumor dwelled in the rectosigmoid area, defineci as 3 cm from peritýmeal reflection. And 80% of the cases with rectosigmoid function tumors were presented with largle bowel obstruction. Five patients could be followed for 3 years.
CONCLUSION: Left colon tumors are known to present with ohstruction most frequently than the other sities. Herein, we conclude that rectosigmoid junction tumors are presented with obstruction more than other region in colon and rectum.


Rektosigmoid Köşe Tümörleri ve Kolonik Obstrüksiyon

AMAÇ: Kolonik intestinal obstrüksiyonun en sýk nedeni kolon tümörleridir. Sol kolon tümörleri obstrüksiyon oluş­turan kolon tümörlerinin %70'ini oluşturmaktadýr. Bu çalýşmanýn amacý rektosigmoid köşe tümörlerinin obstrüksiyon sýklýðýný araştýrmak ve izlem sonuçlarýný bildirmektir.
MATERYAL VE METOD: Kliniğimize 1992-1997 yýllarý arasýnda 67 kolon tömürlü hasta başvurmuş, bunlardan 19’unda (%28.3) tümöre bağlý kolon obstrüksiyonu saptanmýş ve çalýþmamýza dahil edilmiştir.
BULGULAR: Çalýşmamýzda 19 obstrüksiyon oluşmuş olgunun 12'sinde (%63) tümör rektosigmoid köşede bulunmakta idi. Bu bölge tümörlerinin obstrüksiyonla başvurma sýklýðýnýn %80 olduğu saptanmýştýr. üç yýl izlenebilen hasta sayýs 5' tir.
SONUÇ: Sol kolon tümörlerinin en sýk obstrüksiyonla baş­ vuran kolorektal tümörler olduğu bilinmektedir. Çalýşma­mýz rektosigmoid kiişe tümörlerinin büyük sýklýkla (%80) obstrüksiyorýa neden olduğunu göstermektir.
