Clinical characteristics of non-perianal fistulating Crohn's disease in China: a single-center experience of 184 cases.

BACKGROUND: There is little information of non-perianal fistulating Crohn's disease in the consensus published by the European Crohn's and Colitis Organization in 2006 and 2010. This study was designed to demonstrate the clinical characteristics of non-perianal fistulating Crohn's disease among homogenous Chinese population. METHODS: One-hundred-and-eighty-four patients were retrospectively collected. All of these patients were diagnosed of Crohn's disease between February 2001 and April 2011. RESULTS: The male-to-female ratio was 2.7:1. The most common symptoms at onset were abdominal pain (88.0%), diarrhea (34.7%), and fever (28.3%). The most common disease location and behavior at diagnosis were small bowel (56.0%) and penetrating (51.6%). Among 324 non-perianal fistulae, the most common types were ileocolonic anastomotic (30.9%), terminal ileocutaneous (19.7%), and enteroenteric anastomotic (11.4%). One-hundred-and-thirty- eight (75.0%) patients received antibiotics, and ß-lactam (85.5%) and metronidazole (67.4%) are most frequently used. One-hundred-and-seventy-eight (96.7%) patients suffered 514 surgical operations, and the cumulative surgical rates after 1, 3, and 5 years were 38.0%, 52.2%, and 58.7% respectively. Nine patients died during the follow-up period, and the cumulative survival rates after 1, 3, and 5 years were 97.8%, 96.7%, and 96.2% respectively. CONCLUSIONS: This study displayed the clinical characteristics of non-perianal fistulating Crohn's disease in our center. Large population-based studies are required for further investigation in China.

Poor 1-year survival in elderly patients undergoing nonelective colorectal resection.

BACKGROUND: Colorectal resection in elderly patients is associated with significant morbidity and mortality, especially in an emergency setting. OBJECTIVES: This study aims to quantify the risks associated with nonelective colorectal resection up to 1 year after surgery in elderly patients. DESIGN: This is a population-based observational study. SETTING: Data were obtained from the Hospital Episode Statistics database. POPULATION: All patients aged 70 years and older who underwent a nonelective colorectal resection in an English National Health Service Trust hospital between April 2001 and March 2008 were included. MAIN OUTCOME MEASURES: : The primary outcomes measured were 30-day in hospital mortality, 365-day mortality, unplanned readmission within 28 days of discharge, and duration of hospital stay. RESULTS: During the study period, 36,767 nonelective colorectal resections were performed in patients aged ≥ 70 years in England. Patients were classified into 3 age groups: A (70-75 years), B (76-80 years), and C (>80 years). Thirty-day mortality was 17.0%, 23.3%, and 31.0% in groups A, B, and C (p < 0.001). The overall 30-day medical complication rate was 33.7%, and the reoperation rate was 6.3%. Cardiac and respiratory complications were significantly higher in group C (22.2% and 18.2%, p < 0.001). Mortality in Group C was 51.2% at 1-year postsurgery. Advanced age was an independent determinant of mortality in risk-adjusted regression analyses. LIMITATIONS: This is a retrospective analysis of a prospective database. Stage of disease at presentation, severity of complications, and cause of death cannot be ascertained from this database. CONCLUSIONS: In this population-based study, half of all English patients aged over 80 years undergoing nonelective colorectal resection died within 1 year of surgery. Further research is required to identify perioperative and postdischarge strategies that may improve survival in this vulnerable cohort.

Mortality and morbidity associated with late diagnosis of anorectal malformations in children.

AIM: The aim of this study was to highlight the timing of diagnosis of anorectal malformations and the morbidity and mortality associated with any delay. METHODS: We retrospectively reviewed all patients with anorectal malformations presenting to the Children's Hospital, Leicester between 1998-2005. Patient demographics included age at diagnosis, presenting complaint, type of anorectal malformation and sex. Associated malformations were carefully recorded as well as morbidity and mortality occurring as a consequence of the delay in diagnosis. RESULTS: Out of a total of 52 patients, 28 (53%) had delay in diagnosis of the malformation. This delay was associated with significant morbidity in 19% and sadly included two deaths (4%), both being directly related to the missed diagnosis. CONCLUSION: Despite the established, routine, systematic pre-discharge examination in all neonates, a significant proportion of anorectal malformations are not diagnosed at this time. This delay is the cause of significant morbidity and mortality. Simple perineal examination will clearly identify the existence of all anorectal malformations and therefore such morbidity and mortality is totally avoidable.

[Anastomotic fistulas after colorectal resection for carcinoma: incidence and treatment in our recent experience]. / Le fistole anastomotiche dopo resezioni coliche e rettali per neoplasia. Incidenza e trattamento nella nostra esperienza recente.

AIM: The incidence of anastomotic fistula after colorectal surgery did not significantly change in the literature during the last years, despite the advances in the treatment with the use of surgical staplers. Taking into account this and other considerations, the authors present their recent experience in the surgical treatment of colorectal carcinoma, referring in particular to anastomotic fistula, related postoperative mortality and results of consequent reoperations. METHODS: From January 1, 2002 to December 31, 2005, 448 patients affected with colorectal cancer were operated on at the Surgical Department of Valduce Hospital in Como, and in 373 cases an anastomosis was performed, subdivided as follows: 144 ileocolic (38.6%), 10 ileorectal (2.7%), 219 colocolic or colorectal (58.7%). RESULTS: Twenty-five out of 373 anastomotic leaks developed (6.7%). In 9 cases (36%), the fistulas spontaneously closed with conservative treatment, while in 16 (64%) reoperation was necessary. With reference to the anatomical site, the leak occurred in 9 out of 144 patients submitted to right hemicolectomy (6.3%), in 14 out of 219 patients after left hemicolectomy or anterior resection of the rectum (6.4%) and in 2 out of 10 patients (20%) after total colectomy. The following is a detailed report of the therapeutic choices adopted by the authors. Four out of 16 reoperated patients (25%) died postoperatively from infective complications related to the fistula, while the total postoperative mortality was 2.2% (10/448). Therefore, anastomotic dehiscence was responsible for 40% of all postoperative deaths. CONCLUSIONS: Among all the different operative choices, the authors give their preference to the direct suture of the fistula and loop ileostomy, which they consider the best available choice. The subsequent operation of ileostomy closure is easier for the surgeon to perform and for the patient to withstand than colostomy closure, particularly after Hartmann's operation.

[Hemorrhoidectomy--a simple operation? Incontinence, stenosis, fistula, infection and fatalities]. / Die Hämorrhoidektomie--eine einfache Operation? Inkontinenz, Stenose, Fistel, Infektion und Todesfälle.

Hemorrhoidectomy is not a simple procedure. Hemorrhoids develop as hyperplastic formations of an important part of the anorectal organ of continence, i.e., the corpus cavernosum recti. This organ segment is analogous to tissue structures found in the tongue of certain birds which are used for hulling seeds. Well-meaning, complete resection of the corpus cavernosum will inevitably result in incontinence. Only operative techniques which resect exclusively those segments of the hemorrhoidal tissue adjacent to the muscle layer in the anal canal are adequate. These procedures will spare sufficient tissue of the corpus cavernosum to allow a safe segmental resection of this structure and at the same time permanently eradicate the hemorrhoids. In the present paper, the treatment of 53 patients with postoperative incontinence and of others with stenoses, fistulas and pelvic infections is discussed. Fatalities have never been reported in the literature following operative hemorrhoidectomy, however, have occurred after "banding" procedures and after injection therapy.
