The incidence of complications after colonoscopy is very low. The complications after colonoscopy that are of clinical concern are bleeding and perforation. The present study was conducted to determine the clinical outcomes and the risk factors of a colostomy or a colectomy after colonoscopic colon perforation.
From March 2009 to December 2012, the records of all patients who were treated for colorectal perforation after colonoscopy were reviewed retrospectively. The following parameters were evaluated: age, sex, purpose of colonoscopy, management of the colonic perforation, and interval from colonoscopy to the diagnosis of a colonic perforation. A retrospective analysis was performed to determine the risk factors associated with major surgery for the treatment of a colon perforation after colonoscopy.
A total 27 patients were included in the present study. The mean age was 62 years, and 16 were males. The purpose of colonoscopy was diagnostic in 18 patients. The most common perforation site was the sigmoid colon. Colonic perforation was diagnosed during colonoscopy in 14 patients, just after colonoscopy in 5 patients, and 24 hours or more after colonoscopy in 8 patients. For the treatment of colonic perforation, endoscopic clipping was performed in 3 patients, primary closure in 15 patients, colon resection in 2 patients, Hartmann's procedures in 4 patients, and diverting colostomy in 3 patients. If the diagnosis of perforation after colonoscopy was delayed for more than 24 hours, the need for major treatment was increased significantly.
Although a colonic perforation after colonoscopy is rare, if the morbidity and the mortality associated with the colonic perforation are to be reduced, prompt diagnosis and management are very important.

A major outcome of importance for rectal cancer is local control. Parallel to improvements in surgical technique, adjuvant therapy regimens have been tested in clinical trials in an effort to reduce the local recurrence rate. Nowadays, the local recurrence rate has been reduced because of both good surgical techniques and the addition of radiotherapy. Based on recent reports in the literature, preoperative chemoradiotherapy is now considered the standard of care for patients with stages II and III rectal cancer. Also, short-course radiotherapy appears to provide effective local control and the same overall survival as more long-course chemoradiotherapy schedules and, therefore, may be an appropriate choice in some situations. Capecitabine is an acceptable alternative to infusion fluorouracil in those patients who are able to manage the responsibilities inherent in self-administered, oral chemotherapy. However, concurrent administration of oxaliplatin and radiotherapy is not recommended at this time. Radiation therapy has long been considered an important adjunct in the treatment of rectal cancer. Although no prospective data exist for several issues, we hope that in the near future, patients with rectal cancer can be treated by using the best combination of surgery, radiation therapy, and chemotherapy in near future.

Although there are more than a hundred techniques, including the transabdominal and the perineal approaches, for the repair of the rectal prolapsed, none of them is perfect. The best repair should be chosen not only to correct the prolapse but also to restore defecatory function and to improve fecal incontinence throughout the patient's lifetime. The aim of this retrospective review is to evaluate clinical outcomes of the Delorme's procedure for the management of the complete rectal prolapse.
A total of 19 patients (13 females and 6 males) with complete rectal prolapses were treated by using the Delorme's procedure in St. Vincent's Hospital, The Catholic University of Korea, from February 1997 to February 2007. Postoperative anal incontinence was evaluated using the Cleveland Clinic Incontinence Score.
All 19 patients had incontinence to liquid stool, solid stool, and/or flatus preoperatively. Three (15.8%) patients reported recurrence of the rectal prolapse (at 6, 18, 29 months, respectively, after the operation). Information on postoperative incontinence was available for 16 of the 19 patients. Twelve of the 16 patients (75%) reported improved continence (5 [31.3%] were improved and 7 [43.7%] completely recovered from incontinence) while 4 patients had unchanged incontinence symptoms. One (6.3%) patient who did not have constipation preoperatively developed constipation after the operation.
The Delorme's procedure is associated with a marked improvement in anal continence, relatively low recurrence rates, and low incidence of postoperative constipation. This allows us to conclude that this procedure still has its own role in selected patients.

The purpose of this study is to evaluate the value of nonoperative treatment for right-sided colonic diverticulitis.
One hundred fifty-eight patients with right-sided colonic diverticulitis were evaluated. Clinical history, physical and radiologic findings, and treatments were reviewed retrospectively. Also, additional episodes and treatment modalities were checked.
Our patients were classified according to treatment modality; 135 patients (85.4%) underwent conservative treatment, including antibiotics and bowel rest, and 23 patients (14.6%) underwent surgery. The mean follow-up length was 37.3 months, and 17 patients (17.5%) underwent recurrent right-sided colonic diverticulitis. Based on treatment modality, including surgery and antibiotics, no significant differences in the clinical features and the recurrence rates were noted between the two groups.
Conservative management with bowel rest and antibiotics could be considered as a safe and effective option for treating right-sided colonic diverticulitis. This treatment option for right-sided colonic diverticulitis, even if the disease is complicated, may be the treatment of choice.

The lung is the second most common site of metastasis from colorectal cancer. Of all patients who undergo a curative resection for colorectal cancer, 10% to 15% will develop lung metastasis. As a hepatic resection of colorectal liver metastases results in improved survival, many reports have suggested that a pulmonary resection of a colorectal lung metastasis would also improve survival. The aim of this study was to analyze the postoperative outcomes of and the prognostic factors for a surgical resection of a lung metastasis.
Between August 1997 and March 2006, 27 patients underwent surgical resections for colorectal lung metastases at Seoul St. Mary's hospital. A retrospective review of patients' characteristics and various tumor factors was performed.
The mean interval between colorectal resection and lung metastasis was 24.0 ± 15.1 months. The overall 3- and 5-year survival rates were 76.5% and 22.2%, respectively. The mean follow-up after pulmonary resection was 39.5 ± 21.6 months (range, 3.3 to 115 months). Except for the existence of hilar-lymph-node metastasis (P < 0.001), no risk factors that we studied were statistically significant. Two patients had hilar-lymph-node metastasis. They survived for only for 3.3- and 11.6-months, respectively.
In our study, we found that a pulmonary resection for metastases from colorectal cancer may improve survival in selected patients.

The physiology of the anorectal region is very complex, and it is only recently that detailed investigations have given us a better understanding of its function. The methods that are used for the evaluation of anorectal physiology include anorectal manometry, defecography, continence tests, electromyography of the anal sphincter and the pelvic floor, and nerve stimulation tests. These techniques furnish a clearer picture of the mechanisms of anorectal disease and demonstrate pathophysiologic abnormalities in patients with disorders of the anorectal region. Therefore, therapeutic recommendations for anorectal disease can be made best when the anatomy and the physiology of the anorectal region are understood.
