ObjectiveTo investigate the value of postoperative CT examination for evaluation of local complications in patients with low rectal carcinoma after total mesorectal excision with anal sphincter preservation. MethodsThe patients with low rectal carcinoma who received total mesorectal excision (TME) with anal sphincter preservation were examined using contrastenhanced CT in one year period from May 2009 to May 2010. Particular attention was paid to the presence of anastomotic leakage, local recurrence and status of lymph nodes. ResultsTotal of 82 patients (52 men, 30 women； mean age 57.8 years old； range 25.74 years old) were included in the study. Over a mean 10-month follow-up， 8 cases （9.8%） had clinically or surgically confirmed anastomotic leak, 6 cases （7.3%） had local recurrence around the anastomotic site， and 4 cases （4.9%） showed pelvic and distant metastatic lymphadenopathy. ConclusionPostoperative CT examination, including baseline and follow-up CT studies, is very useful for diagnosing anastomotic leakage, local tumor recurrence and lymphadenopathy.
Objective To discuss the strategies for building the framework of team culture of multi-disciplinary team (MDT) for colorectal cancer. Methods By comprehending the traditional concept of volunteer and probing into the value of traditional team culture, combining the needs of MDT for colorectal cancer, build appropriate team culture and core idea of MDT for colorectal cancer. Results Confirm that building of volunteers groups and the volunteers culture is the core of the team culture of MDT for colorectal cancer. Analyze characters of volunteers groups and the operation strategies, and find the way of maintaining the volunteers culture. Conclusion With the development of volunteers groups and increased participants, the team culture of MDT for colorectal cancer will show more sociality and extent. And it is also the important idea and direction for development in future. As team culture, organization structure and personnel structure supplements each other, adjusting and perfecting the team culture in practice continually is a long-term work for MDT.
Objective To investigate the prophylaxes, diagnosis and treatment of pelvi-peritoneal hernia (PPH) after Miles operation for rectal carcinoma. Methods Three hundred and nine patients who underwent Miles operation from January 1986 to June 1999 were collected and analysed retrospectively, 11 of them were complicated with PPH. Results The morbidity of PPH after Miles operation was 3.6% (11/309). The main manifestations included abdominal distention to some extent (11 cases), pain (3 cases), vomiting (2 cases), gastric liquid more than 500 ml a day by gastric tube (3 cases), and non-exsufflation of the stoma of colostomy (11 cases). Two cases had pea green small intestinal liquid by perineal tube. The signs were slight abdominal tender (5 cases), active or excessive intestinal gurgling sound (7 cases), and diminished intestinal gurgling sound (4 cases). Abdominal plane films, showing the distant small intestinal obstruction, were taken in all 11 cases. Only 2 patients were correctly diagnosed before reoperation, and other patients were regarded as adhesive intestinal obstruction. The average observational time following appearance of the clinical manifestations after Miles operation was 7.4 days. All patients were diagnosed by laparotomy, 3 of them underwent adhesion lysis and reposition, and 8 patients partial ileum resection and anastomosis. The content of the hernias was ileum. The morbidity after reoperation was 27.3% (3 cases), and the complication was wound infection. All 11 patients were cured and left hospital. Conclusion The PPH after Miles operation is often lack of typical clinical manifestations. The early diagnosis and laparotomy in time is key to management. It is important to prevent the complication.
【Abstract】ObjectiveTo review recent studies on Muir-Torre syndrome (MTS) and to improve the knowledge about MTS.MethodsThe literatures in recent years on clinic and gene research of MTS were reviewed.ResultsMTS was is a rare autosomal-dominant disorder characterized by the predisposition to both sebaceous tumors (or multiple keratoacanthomas) and internal malignancies. Gastrointestinal cancers were the most common kind of internal malignancies in MTS patients(61%)，followed by genitourinary cancers(22%). In most cases(56%)，sebaceous tumors appeared after the emergence of internal maliganancy. Both hereditary nonpolyposis colorectal cancer(HNPCC) and MTS were caused by germline mutations in the DNA mismatch repair genes. MTS patients exhibit significantly more mutations in the hMSH2 than in the hMLH1. In these cases , both internal and skin tumors showed the characteristic of high microsatellite instability(MSI).ConclusionThe presence of sebaceous tumors(or multiple keratoacanthomas) necessitates the search for internal malignancies. It is mandatory that patients with MTS, as patients with HNPCC, should be regularly followed up to search new malignancies. Evaluation and monitoring of the family members of patients are also necessary. The patients and their families should be counseled for genetic test. Sequencing the hMSH2 gene should be the prior selection of further examinations when clinical manifestations, history and laboratory tests suggest MTS.
Objective To evaluate the feasibility and clinical outcomes of laparoscopic total mesorectal excision (TME) in treating mid-low rectal cancer. Methods From March 2005 to July 2008, 74 patients with mid-low rectal cancer undergoing laparoscopic TME in Zhejiang Cancer Hospital were collected. The data of clinicopathologic parameters were analyzed. Results Laparoscopic TME was performed on 74 patients with mid-low rectal cancer. No operative death occurred in this group. No case was converted to open procedure. The mean operation time was 187 min. The mean operative blood loss was 90 ml. The mean postoperative hospital stay was 10 d. Bowel function was restored on 46 h after operation on average. The mean distance between tumor and the section edge was 3.1 cm. The average number of lymph node dissection was 19.7. The sphincter preservation rate was 97% in patients with tumor 6 cm above the anal verge. The follow-up times were 2-44 months, average 25 months. The incidence of complications was 9.5%. No tumor cell port site implantation or distant metastasis happened. One case was pelvic recurrence， no patient was dead.Conclusion Laparoscopic TME is a feasible, safe and minimally invasive technique for the patients with mid-low rectal cancer, achieving the principles of TME.
目的 探讨结肠癌和直肠癌并发肠穿孔的外科诊治方法。方法 分析13例结直肠癌并发肠穿孔患者的临床资料。结果 13例患者中4例行肿瘤所在肠段一期切除吻合术； 4例行一期病灶切除吻合术，近端肠段行外置双管造瘘术； 2例切除肿瘤所在肠段，近端行端式结肠造瘘术，远端行封闭（Hartmann）术； 3例行单纯肠造瘘术。术后并发症发生率为46.15%（6/13），手术死亡率为15.38%（2/13）。结论 重视对结直肠癌并发肠穿孔的认识及选择合适的手术方式是减少并发症、提高疗效的重要措施。
Objective To evaluate the safety and ascendancy of small caliber stapler application for anterior resection in ultra-low rectal cancer with anal sphincter preservation. Methods A retrospective analysis of the data of 60 cases of ultra-low rectal cancer treated by anterior resection with anal sphincter preservation by double stapling technique according to TME principle between June 2006 and June 2009 were undertaken. The 60 patients were divided into two groups, each group included 30 cases. One group adopted 33 mm stapler and another group adopted 29 mm stapler, and then the profiles of medi-operation, post-operation, and prognosis were assessed. Results Time of simple anastomose in operation was (9.0±3.3) min in 33 mm stapler group and (6.0±2.6) min in 29 mm stapler group, and there was significant difference between them (P=0.022 5). There were 6 cases needed to be restored because of lesion during operation or dys-anastomosis in 33 mm stapler group, while 2 cases in 29 mm stapler group, there was significant difference between them (P=0.030 1). No significant differences were observed between the two groups in terms of the time for operation, leakage, bleeding, stenosis, anastomotic recurrence, and fecal incontinence after operation or length of stay. Conclusion The application of 29 mm stapler not only can shorten time for anastomose and step down the degree of difficulty, but also dosen’t increase stenostomia and other complications.
