Objective To investigate the clinicopathological characteristics and factors influencing the prognosis of rectal carcinoid. Methods Clinical data of 31 cases with rectal careinoid, which identified diagnosis through operation and pathologic examination from January 2003 to March 2010 were retrospectively reviewed. Primary tumors were classified by size （≤1.0 cm， 1.0-2.0 cm， and ＞2.0 cm）and muscularis invasion respectively, compared therapeutic effect of different groups. Results Median age of 31 cases was 49 years (22-83 years). Median follow-up time was 36 months (15-86 months), follow-up rate was 80.6% （25 /31）. During the follow-up period, there were no cases with recurrence among the 15 patients with tumor size≤l.0 cm, 1 case recurred in the 7 patients with turmor size between 1.0 cm to 2.0 cm, and 2 cases died from postoperative liver metastasis among the 3 patients with tumor size＞2.0 cm.There were relations between the tumor size, invasion depth, and metastasis （P＜0.05）. Metastasis and invasion depth of tumor were possibility increment to follow the aggrandizement of the diameter of rectal carcinoid. Conclusion The diameter of rectal carcinoid and muscularis invasion may be important factors affecting survival, which may be an important basis for the choice of operative mode.
Objective Both stapled transanal rectal resection (STARR) and vaginal bridge repair are new operative techniques for treatment of rectocele transanal and transvaginal, respectively. In this study we observe the clinical outcomes for STARR as compared with vaginal bridge repair procedure. Methods The clinical data of 31 patients with obstructive defecation syndrome from January 2007 to May 2009 were retrospectively analyzed. The patients were divided into 2 groups according to different operative approach: STARR group (n=18) and bridge repair suture group (n=13). The clinical outcomes observed were operative time, blood loss, length of stay, cost of hospitalization, complication and the improvement of obstructed defecation syndrome. Results There was no difference in the age and severity in the patients of two groups. Evaluation of the clinical outcomes showed 16 (88.9%) patients in the STARR group and 6 (46.2%) in the bridge repair suture group reported improvement in symptoms (P=0.017). STARR had a shorter operative time (24.6 min vs. 33.2 min， Plt;0.01), less estimated blood loss (3.9 ml vs. 16.2 ml， Plt;0.01), more costly (10 743 yuan vs. 3 543 yuan, Plt;0.01) and a higher anal incontinenc rate but reversible. The length of stay was similar (average 6 d). Conclusion The stapled transanal rectal resection procedure is more superior to the vaginal bridge repair suture for improvement of obstructed defecation syndrome from rectocele, however, it has a higher cost and some patient with reversible slight anal incontinence after surgery.
Objective To evaluate the feasibility, safety, radicality, and short-term and mid-term clinical outcomes of laparoscopic total mesorectal excision （TME） in comparison with open procedure for the middle-lower rectal cancer. Methods From October 2005 to October 2008， 52 patients with middle-lower rectal cancer received laparoscopic TME （Dixon’operation） without preventive stoma， while 46 patients underwent conventional open TME （Dixon’operation） without preventive stoma. The operative procedures, clinicopathological data， and short-term and mid-term outcomes were collected and compared between the two groups. Results The other patients were successful in both groups in addition to 2 （3.8%） patients were converted to open procedure in laparoscopic TME group. There was no perioperative death in both groups. The intraoperative blood loss, the time for bowel movement retrieval （first flatus）， and the incision healing in laparoscopic TME group were better than that in open TME group （P＜0.05）. No significant differences were observed between two groups in anastomotic leakage and pulmonary infection （P＞0.05）. Comparison of specimen, no significant differences were observed between two groups in negative distal margin and circumferential resection margin, number of lymph nodes resected, distance of distal resection margin to the tumor （P＞0.05）. No significant differences were observed between two groups in cancer-related death, local recurrence, distant metastasis, and 3-year survival rate （P＞0.05）. Conclusions Laparoscopic TME for middle-low rectal cancer is a safe, feasible, and minimally invasive technique, and can achieve satisfactory oncological outcome, which provides similar short-term and mid-term outcome compared with the traditional open procedure.
Objective To investigate the feasibility of laparoscopic-assisted transanal everted pull-through resection and anastomosis in the treatment for ultra-low rectal cancer （the inferior margin of the tumor from the anal margin of less than 5cm）. Methods From December 2006 to December 2009，46 patients with ultra-low rectal cancer had been undergone laparoscopic-assisted transanal everted pull-through resection and anastomosis. The intraoperative condition，postoperative complications，and the result of follow-up were analyzed retrospectively. Results The operation was successfully performed on all the patients. The intraoperative blood loss was （202±56） ml （100-290m1）. The time of recovery of gastrointestinal function was （60±16） h （36-82 h）. No anastomotic bleeding or stomal leak was observed. All the patients were followed-up for （31±5） months （21-45months），15 patients developed mild to moderate anastomotic stricture，1 local recurrence， and 2 liver metastasis. All the patients had no anal incontinence 10months after stoma closure operation， the defecation of all the patients became normal （4.5±1.2） months（2-10months） later. Conclusions Laparoscopic-assisted transanal everted pull-through resection and anastomosis for ultra-low rectal cancer is safe and feasible， and the effect is satisfactory.
