The distinctive diagnosis of Crohn's disease (CD) and ulcerative colitis (UC) is based on a combination of clinical, histologic, endoscopic, and radiologic data. Both UC and CD show characteristic, but non-specific, pathological features that may overlap and result in a diagnosis of indeterminate colitis (IC), which was proposed by pathologists for colectomy specimens in 1978, usually from patients operated on for severe colitis, especially in cases of acute fulminant disease of the colorectum. The subgroup of patients with an uncertain diagnosis has been classified as IC. Later, the same terminology was used for patients showing no clear clinical, endoscopic, histologic, or other features allowing a diagnosis of either UC or CD. More recently, the term IC has been applied to biopsy material when it is not been possible to differentiate between UC and CD. However, this term IC has suffered varying definitions, which in addition to numerous difficulties in diagnosing inflammatory bowel disease, has led to much confusion. In resected specimens, the term colitis of uncertain type or etiology is preferred. Over time, the majority of patients remain with a diagnosis of IC or show symptoms similar to UC. Ileal pouch anal anastomosis can be performed in such patients, with outcomes of pouch failure and with functional outcomes that are similar to those in patients with UC, but with increased risk of postoperative pouch complications. This review addresses the definition of indeterminate colitis, its pathology, its natural history, and the outcomes of restorative proctocolectomy.

Familial adenomatous polyposis (FAP) is an hereditary autosomal dominant disease characterized by development of hundreds to thousands of adenomatous polyps in the colon and rectum. The common symptoms are bloody stool, diarrhea, and abdominal pain. The average age at onset of symptoms is 33 years. Because of inevitable progression to malignancy, it is necessary to remove the entire colonic and rectal mucosa. Current surgical options are total proctocolectomy with permanent ileostomy, trans-abdominal colectomy with ileorectal anastomosis (IRA), and restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). Recently IPAA can give optimum control of colorectal polyposis in FAP patients with an acceptable incidence of postoperative complications and satisfactory functional results. We experienced one case of FAP who had malignacy in the remained rectum after subtotal colectomy. IPAA was done and the result was satisfactory.

Hereditary colorectal cancer accounts for approximately 5% of all colorectal cancer cases, mainly including familial adenomatous polyposis and Lynch syndrome. Total proctocolectomy plus ileal pouch-anal anastomosis and total colectomy plus ileorectal anastomosis are two major procedures for familial adenomatous polyposis, however, the exact impact of these two procedures on surgical efficacy, oncologic efficacy as well as functional results still remains uncertain. Segmental colectomy and total colectomy are two major procedures for Lynch syndrome, each of them both has advantages and disadvantages, and there still lacks a consensus about the optimal strategy because of the nature of retrospective study with a relatively insufficient evidence support. As a result, we would make a review about the current surgical treatment status and future perspectives of hereditary colorectal cancer.

OBJECTIVETo compare primary anastomosis after intraoperative colonic defecation and Hartmann procedure for obstructive left colon cancer.

METHODSClinical data of 68 patients who underwent emergent laparotomy for left colon cancer with acute bowel obstruction between January 2000 and January 2008 were analyzed retrospectively.

RESULTSPrimary resection and anastomosis with intraoperative defecation was performed in 43 patients and Hartmann's procedure in 25 cases. Patients in both groups were comparable in terms of age, gender, nutritional status, underlying diseases, tumor location and stage, etc. The morbidity and mortality in the two groups were 25.6% vs 28.0% (P=0.761) and 2.3% vs 4.0% (P=0.369), respectively, and the differences were not statistically significant. The length of hospital stay (including first resection operation and second admission for colostomy closure) was (16.6+/-7.8) d in the primary anastomosis group and (24.6+/-9.4) d in the Hartmann procedure group, and the difference was statistically significant (P=0.002). The costs of hospitalization in the two groups were CNY 50,192.8+/-39,727.4 and CNY 58,382.1+/-30,304.9 (P=0.020).

CONCLUSIONPrimary resection with intraoperative colonic defecation is safe and effective, and should be considered as an alternative to Hartmann procedure for obstructive left colon cancer in selected patients.

OBJECTIVETo evaluate the safety and feasibility of hand-sewn anastomosis in totally laparoscopic colectomy.

METHODSClinical data of 19 consecutive patients with benign(n=5) or malignant colonic diseases(n=14, 4 ascending colon cancers, 2 transverse colon cancers, and 8 sigmoid colon cancers) treated with totally laparoscopic colectomy with a hand-sewn anastomosis were reviewed. All the procedures were performed by the same surgeon team including totally laparoscopic resection and hand-sewn anastomosis, ileocolic anastomosis after right hemicolectomy, and hand-sewn purse-string sutures in the colon.

RESULTSHand-sewn anastomosis was performed for 11 patients and circular-stapled anastomosis with hand-sewn purse-string sutures was performed for other 8 patients. The mean hand-sewn anastomosis time was (49.5 ± 29.4) min, and the mean hand-sewn purse-string sutures time was (13.3 ± 5.5) min. No patients required conversion to laparoscopy-assisted or open surgery, and there were no postoperative complications related to anastomosis. One patient with transverse colon lipoma developed mild intra-abdominal infection after surgery and recovered after conservative treatment.

CONCLUSIONTotally laparoscopic intracorporeal hand-sewn anastomosis or hand-sewn purse-string sutures for colectomy is feasible and safe when performed by experienced laparoscopic surgeons.

Circumferential resection margin(CRM) is the closest distance from the deepest of tumor invasion to the surgical margin of mesentery. It has been well known that CRM has significant impact on the prognosis and treatment of rectal cancer. However, the significance of CRM of colon cancer is just brought to the forefront recently. Current evidence showed positive rate of CRM is 10%, and the patients with positive CRM have worse survival. The factors influencing CRM include tumor stage, differentiation, vascular cancer embolus, etc. Standard surgical procedure can lower the positive rate of colon CRM, and adjuvant therapy applied to the patients with positive colon CRM can improve the survival of colon cancer patients. CRM may become a new factor guiding the treatment in colon cancer patients.

BACKGROUND/AIMS: A number of studies have reported wide variability in the colonoscope insertion time among patients who had prior abdominal surgery. The aim of this study was to investigate the effect of abdominal surgery on colonoscope insertion time. METHODS: The subjects were 192 patients with prior abdominal surgery, among 3,600 patients who underwent a colonoscopy at Samsung Changwon Hospital from May 2008 to May 2010. We collected the following data: insertion time, age, gender, height, weight, BMI, waist circumference, method of abdominal surgery, and the degree of bowel cleanliness. Previous abdominal operations were divided into colectomy, non-colectomy abdominal surgery, pelvic surgery, and laparoscopic surgery groups. RESULTS: The average colonoscope insertion time in patients with prior abdominal surgery (7.73+/-5.95 min) was longer than that of the non-surgery group (6.4+/-3.88 min). Patients in the colectomy groups were older and had a shorter insertion time (5.11+/-3.32 min) than patients in the other groups. CONCLUSIONS: Insertion of a colonoscope in patients with previous abdominal surgery was more difficult than that in the control group, except the colectomy group.
