Fifteen patients with rectal carcinoid tumors were treated from 1975 to 1991. Before admision, nine patients (60%) had been misdiagnosed as polyps ,hemorrhoids or proctitis. Diagnosis may be delayed because of failure to recognize their charasteristics and by the negligeuce of doing digital examination or proctoscopy. Some aspects of the management of these tumors remain controversial. However, present-day treatment programs call for radical cancer resections only for lesions 2cm in diameter or larger, and local resections for all others. In reviewing this series of cases and other studies, we advocate that both the size of the lesion and the depth of tumor invasion should be taken as the criteria of surgical managements. If the tumor is 2cm in diameter, or smaller than that, local resection can be performed, but whenever the nuscularis propria is invaded, radical resection should be performed. Radical resection is bly indicated for tumors larger than 2cm.
【Abstract】Objective To discuss the clinical significance of postoperative application of gastrointestinal decompression after anastomosis of lower digestive tract. Methods Three hundred and sixty-eight patients undergoing excision and anastomosis of lower digestive tract were divided into two groups: the group with postoperative gastrointestinal decompression and the group without it. The clinical therapeutic outcomes and incidences of complications were compared between the two groups. Results The volume of gastric juice in the decompression group was about 200 ml every day after operation. Both groups had a smaller abdomenal circumference before operation than after operation （P＜0.001）. No difference in the time of first passage of gas from anus and defecation after operation was found between the two groups. The incidence of complications in the decompression group was obviously higher than that of non-decompression group (28.0% vs. 8.2%, P＜0.001); the incidence of pharyngolaryngitis of the former was up to 23.1%. There was also no difference found between these two groups regarding the hospital stay after operation.Conclusion The present study shows that application of gastrointestinal decompression after excision and anastomosis of lower digestive tract cannot effectively reduce the gastrointestinal tract pressure and has no obvious effect on prevention from postoperative complications. On the contrary, it may increase the incidence of pharyngolaryngitis and other complications. Therefore, it is more beneficial for the recovery of patients without gastrointestinal decompression.
2.6.2.2 经骶直肠癌局部切除术（trans-sacrococcygeal resection,TSR）(1)ＴＳＲ手术指征①肿瘤部位: 部位是选择TSR 的决定性因素之一,原则上腹膜返折以下的早期直肠癌均可通过TSR 完成,但理想部位是距齿状线4～6 cm 的直肠癌,切口可直达病灶,在咬除尾骨后游离直肠范围较小,得以轻松显露接近腹膜返折甚至距肛缘8～10 cm 的直肠中段肿瘤。②肿瘤方位: TSR 最适合的还是直肠后壁或后侧壁病变,前壁或前侧壁肿瘤的直肠游离要做到界面层次清晰则需要术者具备相当的经验。③肿瘤大小: 无论瘤体大小(瘤体直径＜3 cm),肿瘤基底直径应＜2 cm,尤其是浅溃疡型肿瘤,还要考虑到直肠壶腹的宽窄大小。④肿瘤形态: TSR仅适合于息肉隆起型或扁平隆起型病变,也包括浅溃疡型癌。⑤肿瘤浸润深度: 肠腔内窥镜超声检查理应成为术前分期的常规检测手段和临床指南,临床上通过仔细检查肿瘤基底活动度来判断其浸润..............
