A 30-yr-old man was referred for suspicious rectal cancer because of ulcerated lesions in the rectum and a palpable mass in left inguinal area. Sigmoidoscopy showed two indurated masses and histologic evaluation of biopsy revealed obliterative endarteritis with heavy plasma cell infiltration. Both venereal disease research laboratories (VDRL) and fluorescent treponemal antibody absorption (FTA-ABS) tests were positive. After injection of penicillin G benzathine for 3 weeks, the rectal chancre and the palpable mass disappeared.

Anastomotic leakage (AL) is one of the most serious complications after sphincter- preserving surgery for rectal cancer, which can significantly prolong the length of stay of patients, increase perioperative mortality, cause dysfunction, shorten overall survival and recurrence-free survival of patients. In order to reduce the serious consequences caused by AL, prediction of AL through preoperative and intraoperative risk factors are of great importance. However, the influences of neoadjuvant chemoradiotherapy, protective stoma, laparoscopic surgery and some intraoperative manipulations on AL are still controversial. Through the auxiliary judgment of anastomotic blood supply during operation, such as indocyanine green imaging, hemodynamic ultrasound, etc., it is expected to achieve the source control of AL. Early diagnosis of AL can be achieved by attention to clinical manifestations and drainage, examination of peripheral blood, drainage and intestinal flora, identification of high risk factors such as fever, diarrhea and increased infectious indicators, and timely administration of CT with contrast enema.

We report a case of mucinous adenocarcinoma arising in the perianal soft tissue in association with chronic fistula-in-ano in a 43-year-old man who had a relapse of perianal pain and bloody discharge after six years of defaulted follow-up. He underwent magnetic resonance (MR) and computed tomography imaging with correct identification of the disease entity on imaging. Mesh-like septations and an enhancing solid component with high diffusion-weighted imaging (DWI) and intermediate apparent diffusion coefficient signals were observed. He underwent abdominoperineal resection of the tumour but succumbed due to postoperative complications. Literature on the MR imaging features of this tumour remains scarce. We highlight the MR imaging features, including those seen on DWI, which were useful in making the correct diagnosis. Though uncommon, this would be an important condition to recognise since assessment of fistula-in-ano by MR imaging is considered to be the standard of care in current clinical practice. The clinical features of this entity are also briefly discussed.

Anastomotic leak is one of inevitable postoperative complications of rectal cancer. With the improvement of surgical techniques, the enhancement of the cognization of rectal cancer, and the development of surgical instruments, surgical procedures of rectal cancer are getting more sophisticated. The anastomosis is performed lower and lower, however the incidence of anastomotic leak is not significantly decreased. In addition, different from intraperitoneal anastomotic leak, the low rectal anastomotic leak after low anterior resection has many special issues in the diagnosis and treatment in clinic. The incidence of peritonitis caused by low anastomotic leak is low, the onset time is late, and symptoms of peritonitis are mild. So most low anastomotic leak is treated conservatively, second surgical repair or resection of anastomotic site is rarely performed, and proximal intestinal diversion is commonly performed. In the prevention of low anastomotic leak, some techniques and precautions during the perioperative period and identification of high risk factors might play important roles. Combined our clinical experiences, we introduced the diagnosis, treatment, prevention and research progression of low anastomotic leak after anterior resection of low rectal cancer, we hope it would be helpful.

PURPOSE: Restorative proctocolectomy (RP) is a standard surgery in patients with ulcerative colitis and familial adenomatous polyposis. Usually, diverting ileostomy is performed to protect an ileoanal anastomosis with RP. However, there are many controversies whether diverting ileostomy might urgently be needed. This study was performed to compare postoperative complications after RP with or without diverting ileostomy. METHODS: Between July 1994 and June 2001, 77 (M : F= 45 : 32) patients underwent RP. The indication criteria for diverting ileostomy included tension at the anastomosis, positive leakage test, compromised blood flow in the ileal pouch, long-term and high-dose steroid use, and severe rectal inflammation in ulcerative colitis patients. RESULTS: Histopathologic diagnoses revealed 45 ulcerative colitis, 23 familial adenomatous polyposis, 5 rectal cancer, and 4 hereditary nonpolyposis colorectal cancer. Diverting ileostomies were performed in 40 patients (51.9%) and closed approximately 4 months later. Fourty eight complications were present in 32 patients. There was no perioperative death. There was no difference in perioperative outcome, morbidity or functional status between patients with and without ileostomy. However, in ulcerative colitis patients, anastomosis leakage was more frequent in patients without ileostomy. CONCLUSIONS: Restorative proctocolectomy can be safely performed without diverting ileostomy in most cases of RP. However, diverting ileostomy may reduce anastomosis leakage in patients with ulcerative colitis.

A clinical study was made of 14 cases of distal rectal cancer treated at the Department of Surgery, St. Mary's Hospital, Catholic University Medical College, from January 1995 to April 1996. The patients were treated in a modified Thomas Jefferson program and received high doses of preoperative radiation followed by a sphincter saving procedure. The results are as follows: 1) There were 5 male patients (35.7%) and 9 female patients(64.3%). There was also a large number of patients in their 50s and 60s. 2) The preoperative pathologic type was a moderately differentiated adenocarcinoma. 3) Rectal bleeding was the most common symptom, followed by tenesmus, constipation, anal pain, and a tarry stool. 4) At diagnosis, the Thomas Jefferson (T.J.) system was used for the clinical stage of the patients. The clinical stage of disease showed a preponderance of T.J. stage I (10 patients), T.J stage II, III, and IV occurred in 2, 1, and 1 patient, respectively. 5) The most common site was 0-3 cm above dentate line (8 patients), followed by 4-6 cm (5 patients) and > 7 cm (1 patient) above the dentate line. 6) The complications after preoperative radiation therapy were diarrhea (3 patients) and perianal dermatitis (5 patients). 7) After preoperative radiation therapy, one case showed pathologic complete remission. 8) The procedure was a Transanal Abdominal TransAnal proctosigmoidectomy and coloanal anastomosis (TATA) in 11 patients, a low anterior resection in 1 patient, an abdominal perineal resection in 1 patient, and a colostomy in 1 patient. 9) The pathologic stage showed a preponderance of Duke's B2 and B1; 5 were B2, 4 were B1, 3 were C2, 1 was D, and 1 was O. 10) The postoperative complications after colostomy repair in TATA were frequent defecation, tenesmus, anal pain at defecation, and rectovaginal fistulas which subsided 3 months after colostomy repair.

Situs inversus totalis is a rare anomaly in which the abdominal and thoracic cavity structures are opposite their usual positions. A 41-yr-old woman, who had an ulcerating cancer on the rectum, was found as a case of situs inversus totalis. We present an overview of the operative technique for the first documented laparoscopic total mesorectal excision of a rectal cancer in the patient with situs inversus totalis. Careful consideration of the mirror-image anatomy permitted a safe operation using techniques not otherwise different from those used for the general population. Therefore, curative laparoscopic surgery for rectal cancer in this patient is feasible and safe.

Pseudomembranous colitis (PMC) is known to be associated with the administration of antibiotics which alter normal gastrointestinal flora and allow overgrowth of Clostridium difficile. Most cases of rifampicin-induced PMC are seen in patients with pulmonary tuberculosis, but not with gastrointestinal tuberculosis. We report a case of PMC associated with rifampicin therapy in a patient with gastrointestinal tuberculosis. A 65-year-old female patient with rectal cancer and gastrointestinal tuberculosis was admitted due to abdominal pain and diarrhea. She was treated with anti-tuberculosis agents containing rifampicin. On colonoscopic examination, mucoid exudates and yellowish plaque lesions were observed. Anti-tuberculosis agents were stopped, and the patient was treated with metronidazole. Symptoms were relieved and did not recur when all the anti-tuberculosis agents except rifampicin were started again. When a patient complains of abdominal pain or diarrhea while taking rifampicin, the physician should consider the possibility of rifampicin-associated PMC.
