Necrotizing fasciitis usually occurs after dermal injury or through hematogenous spread. To date, few cases have been reported as necrotizing fasciitis of the thigh secondary to rectal perforation in rectal cancer patients. A 66-year-old male complained of pelvic and thigh pain and subsequently developed necrotizing fasciitis in his right thigh. Four years earlier, he had undergone a low anterior resection and radiotherapy due to of rectal cancer. An ulcerative lesion had been observed around the anastomosis site during the colonoscopy that had been performed two months earlier. Pelvic computed tomography and sigmoidoscopy showed rectal perforation and presacral abscess extending to buttock and the right posterior thigh fascia. Thus, the necrotizing fasciitis was believed to have occurred because of ulcer perforation, one of the complications of chronic radiation colitis, at the anastomosis site. When a rectal-cancer patient complains of pelvic and thigh pain, the possibility of a rectal perforation should be considered.

2.Colouterine Fistula Caused by Diverticulitis of the Sigmoid Colon.
Journal of the Korean Society of Coloproctology 2012;28(6):321-324
Colouterine fistula is an extremely rare condition because the uterus is a thick, muscular organ. Here, we present a case of a colouterine fistula secondary to colonic diverticulitis. An 81-year-old woman was referred to the emergency department with abdominal pain and vaginal discharge. Computed tomography showed a myometrial abscess cavity in the uterus adherent to the thick sigmoid wall. Upon contrast injection via the cervical os for fistulography, we observed spillage of the contrast into the sigmoid colon via the uterine fundus. Inflammatory adhesion of the distal sigmoid colon to the posterior wall of the uterus was found during surgery. The colon was dissected off the uterus. Resection of the sigmoid colon, primary anastomosis, and repair of the fistula tract of the uterus were performed. The postoperative course was uneventful. This case represents an unusual type of diverticulitis complication and illustrates diagnostic procedures and surgical management for a colouterine fistula.

PURPOSE: Placenta growth factor (PlGF) is a member of the vascular endothelial growth factor (VEGF) family. PlGF is implicated in several pathologic processes, including the growth and spread of cancer and tumor angiogenesis. The aim of this study was to evaluate the expression and the clinical implications of PlGF in colorectal cancer. METHODS: In order to ascertain the clinical significance of PlGF expression in colorectal cancer, the researcher analyzed the expression pattern of PlGF by using an immunohistochemical method and attempted to establish if a relationship existed between PlGF expression and microvessel density (MVD), and subsequently between PlGF expression and the predicted prognosis. A total of 83 patients with colorectal cancer were included for immunohistochemical staining. Clinicopathological characteristics were defined according to the tumor-node-metastasis (TNM) criteria of the Union for International Cancer Control. Clinicopathologic factors, such as age, sex, histological types of tumors, tumor cell grade, TNM stage, lymphovascular invasion, and lymph-node metastasis, were reviewed. RESULTS: In this study, the PlGF protein expression level was significantly correlated with MVD, patient survival, and clinicopathological factors such as lymph-node metastasis, TNM staging, lymphatic invasion and vascular invasion. CONCLUSION: PlGF may be an important angiogenic factor in human colorectal cancer, and in this study, PlGF expression level was significantly correlated with positive lymph-node metastases, tumor stage, and patient survival. These findings suggest that PlGF expression correlates with disease progression and may be used as a prognostic marker for colorectal cancer.

PURPOSE: The aim of this retrospective study was to evaluate the rate of recurrence and incontinence after the treatment of fistulae or fistulous abscesses by using the staged drainage seton method. METHODS: According to the condition, a drainage seton alone or a drainage seton combined with internal opening (IO) closure and relocation of the seton was used. After a period of time, the seton was changed with 3-0 nylon; then, after another period of time, the authors terminated the treatment by removing the 3-0 nylon. Telephone interviews were used for follow-up. The following were evaluated: the relationship between the type of fistula and recurrence; the relationship between the type of fistula and the period of treatment; the relationship between the recurrence and presence of abscess; the relationship between IO closure and recurrence; the relationship between the period of seton change and recurrence; reported continence for flatus, liquid stool, and solid stool. RESULTS: The recurrence rate of fistulae or suppuration was 6.5%, but for cases of horseshoe extension, the recurrence rate was 57.1%. The rate of recurrence was related to the type of fistula (P = 0.001). Incontinence developed in 3.8% of the cases. No statistically significant relationship was found between the rate of recurrence and the presence of an abscess or between the closure of the IO and the period of seton change or removal. CONCLUSION: In the treatment of anal fistulae or fistulous abscesses, the use of a staged drainage seton can reduce the rate of recurrence and incontinence.

PURPOSE: For the treatment of acute appendicitis, a conventional laparoscopic appendectomy (LA) has been widely performed. Recently, the use of single incision laparoscopic surgery (SILS) is increasing because it is believed to have advantages over conventional laparoscopic surgery. In this study, we compared SILS and a conventional LA. METHODS: We analyzed the 217 patients who received laparoscopy-assisted appendectomies between August 2010 and April 2012 at Inje University Sanggye Paik Hospital. One hundred-twelve patients underwent SILS, and 105 patients underwent LA. For the two groups, we compared the operation times, postoperative laboratory results, postoperative pain, hospital stay, and postoperative complications. RESULTS: The patients' demographics, including body mass index, were not significantly different between the two groups. There were 6 perforated appendicitis cases in the SILS group and 5 cases in the LA group. The mean operative time in the SILS group was 65.88 +/- 22.74 minutes whereas that in the LA group was 61.70 +/- 22.27 minutes (P = 0.276). There were no significant differences in the mean hospital stays, use of nonsteroidal antiinflammatory drugs, and wound infections between the two groups. CONCLUSION: Postoperative pain, complications and hospital stay showed no statistically significant differences between the SILS and the LA groups. However, our SILS method uses a single trocar and two latex tubes, so cost savings and reduced interference during surgery are expected.

PURPOSE: The purpose of this study was to evaluate the overall rate and risk factors for the development of an incisional hernia and a parastomal hernia after colorectal surgery. METHODS: The study cohort consisted of 795 consecutive patients who underwent open colorectal surgery between 2005 and 2007 by a single surgeon. A retrospective analysis of prospectively collected data was performed. RESULTS: The overall incidence of incisional hernias was 2% (14/690). This study revealed that the cumulative incidences of incisional hernia were 1% at 12 months and 3% after 36 months. Eighty-six percent of all incisional hernias developed within 3 years after a colectomy. The overall rate of parastomal hernias in patients with a stoma was 6.7% (7/105). The incidence of parastomal hernias was significantly higher in the colostomy group than in the ileostomy group (11.9% vs. 0%; P = 0.007). Obesity, abdominal aortic aneurysm, American Society of Anesthesiologists score, serum albumin level, emergency surgery and postoperative ileus did not influence the incidence of incisional or parastomal hernias. However, the multivariate analysis revealed that female gender and wound infection were significant risk factors for the development of incisional hernias female: P = 0.009, wound infection: P = 0.041). There were no significant factors related to the development of parastomal hernias. CONCLUSION: Our results indicate that most incisional hernias develop within 3 years after a colectomy. Female gender and wound infection were risk factors for the development of an incisional hernia after colorectal surgery. In contrast, no significant factors were found to be associated with the development of a parastomal hernia.

Journal of the Korean Society of Coloproctology 2012;28(3):145-151
PURPOSE: Ostomy takedown is often considered a simple procedure without intention; however, it is associated with significant morbidity. This study is designed to evaluate factors predicting postoperative complications in the ostomy takedown in view of metabolism and nutrition. METHODS: A retrospective, institutional review-board-approved study was performed to identify all patients undergoing takedown of an ostomy from 2004 to 2010. RESULTS: Of all patients (150), 48 patients (32%; male, 31; female, 17) had complications. Takedown of an end-type ostomy showed a high complication rate; complications occurred in 55.9% of end-type ostomies and 15.7% of loop ostomies (P < 0.001). Severe adhesion was also related to a high rate of overall complication (41.3%) (P = 0.024). In preoperative work-up, ostomy type was not significantly associated with malnutrition status. However, postoperatively severe malnutrition level (albumin <2.8 mg/dL) was statistically significant in increasing the risk of complications (72.7%, P = 0.015). In particular, a significant postoperative decrease in albumin (>1.3 mg/dL) was associated with postoperative complications, particularly surgical site infection (SSI). Marked weight loss such as body mass index downgrading may be associated with the development of complications. CONCLUSION: A temporary ostomy may not essentially result in severe malnutrition. However, a postoperative significant decrease in the albumin concentration is an independent risk factor for the development of SSI and complications.

PURPOSE: This study was aimed to compare the results of a transanal repair with those of a transvaginal levatorplasty and to determine the long-term clinical outcomes according to the change in the depth of the rectocele after the procedure. METHODS: Of 50 women who underwent a rectocele repair from March 2005 to February 2007, 26 women (group A) received a transanal repair, and 24 (group B) received a transvaginal repair with or without levatorplasty. At 12 months after the procedures, 45 (group A/B, 22/23 women) among the 50 women completed physiologic studies, including anal manometry and defecography, and clinical-outcome measurements. The variations of the clinical outcomes with changes in the depth of the rectocele were also evaluated in 42 women (group A/B, 20/22) at the median follow-up of 50 months. RESULTS: On the defecographic findings, the postoperative depth of the rectocele decreased significantly in both groups (group A vs. B, 1.91 +/- 0.20 vs. 2.25 +/- 0.46, P = 0.040). At 12 months after surgery, 17 women in each group (group A/B, 77/75%) reported improvement of their symptoms. However, only 11 and 13 women (group A/B, 55/59%) of groups A and B, respectively, maintained their improvement at the median follow-up of 50 months. Better results were reported in patients with a greater change in the depth of their rectocele (> or =4 cm) after the procedure (P = 0.001) CONCLUSION: In both procedures, clinical outcomes might become progressively worse as the length of the follow-up is increased.

PURPOSE: This experimental study verified the effect of adipose-tissue-derived stem cells (ASCs) on the healing of ischemic colonic anastomoses in rats. METHODS: ASCs were isolated from the subcutaneous fat tissue of rats and identified as mesenchymal stem cells by identification of different potentials. An animal model of colonic ischemic anastomosis was induced by modifying Nagahata's method. Sixty male Sprague-Dawley rats (10-week-old, 370 +/- 50 g) were divided into two groups (n = 30 each): a control group in which the anastomosis was sutured in a single layer with 6-0 polypropylene without any treatment and an ASCtreated group (ASC group) in which the anastomosis was sutured as in the control group, but then ASCs were locally transplanted into the bowel wall around the anastomosis. The rats were sacrificed on postoperative day 7. Healing of the anastomoses was assessed by measuring loss of body weight, wound infection, anastomotic leakage, mortality, adhesion formation, ileus, anastomotic stricture, anastomotic bursting pressure, histopathological features, and microvascular density. RESULTS: No differences in wound infection, anastomotic leakage, or mortality between the two groups were observed. The ASC group had significantly more favorable anastomotic healing, including less body weight lost, less ileus, and fewer ulcers and strictures, than the control group. ASCs augmented bursting pressure and collagen deposition. The histopathological features were significantly more favorable in the ASC group, and microvascular density was significantly higher than it was in the control group. CONCLUSION: Locally-transplanted ASCs enhanced healing of ischemic colonic anastomoses by increasing angiogenesis. ASCs could be a novel strategy for accelerating healing of colonic ischemic risk anastomoses.

10.A Comprehensive Review of Inflammatory Bowel Disease Focusing on Surgical Management.
Journal of the Korean Society of Coloproctology 2012;28(3):121-131
The two main diseases of inflammatory bowel disease are Crohn's disease and ulcerative colitis. The pathogenesis of inflammatory disease is that abnormal intestinal inflammations occur in genetically susceptible individuals according to various environmental factors. The consequent process results in inflammatory bowel disease. Medical treatment consists of the induction of remission in the acute phase of the disease and the maintenance of remission. Patients with Crohn's disease finally need surgical treatment in 70% of the cases. The main surgical options for Crohn's disease are divided into two surgical procedures. The first is strictureplasty, which can prevent short bowel syndrome. The second is resection of the involved intestinal segment. Simultaneous medico-surgical treatment can be a good treatment strategy. Ulcerative colitis is a diffuse nonspecific inflammatory disease that involves the colon and the rectum. Patients with ulcerative colitis need surgical treatment in 30% of the cases despite proper medical treatment. The reasons for surgical treatment are various, from life-threatening complications to growth retardation. The total proctocolectomy (TPC) with an ileal pouch anal anastomosis (IPAA) is the most common procedure for the surgical treatment of ulcerative colitis. Medical treatment for ulcerative colitis after a TPC with an IPAA is usually not necessary.
