RESUMEN
Background: Treatment of anal fistulas is still a challenging task because of high recurrence and risk of incontinence. Identification of internal fistula opening is paramount for successful treatment. Goodsall's rule is commonly used to predict the course of fistula and internal opening. However, its accuracy has been questioned by many investigators and its role became a controversial topic. Method: This is a case series prospective study in which 320 consecutive patients with anal fistula with Mean age 48.9± 6 years ages (ranges from 16 to 64 years) and mean body mass index 24.8± 5.5 average 18.5-30.6) were enroled. Goodsall's rule was applied to all fistulas according to the site of external fistula opening. Location of internal fistula opening as suggested by Goodsall's rule then compared to the exact location of internal opening identified by perineal or pelvic MRI and intraoperative findings. to assess the accuracy and positive predictive value of the Goodsall's rule in predicting the internal opening of the tract. Results: The overall accuracy rate, positive predictive value (PPV), sensitivity and specificity of Goodsall's rule in this study were 74.75%, 77.1, 74.5, and 72.05, respectively. The accuracy in predicting the internal fistula opening was 52.4% in anterior tracts and 73% in posterior tracts. Goodsall's rule was found to be more accurate in posterior fistulas than anterior fistulas and in short superficial fistulas rather than in long and high fistulas. Conclusion: Goodsall's rule was accurate in 74.75% of anal fistulas. It was more accurate for posterior long fistulas and anterior short and superficial fistulas. Patients with long (>3 cm) anterior fistulas defied Goodsall's rule when they found to have fistulas tracking to a midline anterior origin. Further, short posterior fistulas were found to open more commonly in a direct radial course rather to midline posteriorly.
RESUMEN
BACKGROUND: Obesity could affect many functions of the body systems, particularly respiratory system. Effect of obesity on respiratory system leads to an impairment in pulmonary function tests which is represented by a decrease in lung volumes and capacities, therefore obstructive or restrictive pulmonary diseases may develop. The recent study was conducted to investigate and assess the impact of weight loss by surgery on static and dynamic lung volumes (pulmonary function tests) and the improvement in co morbidities. PATIENTS AND METHODS: The study included 68 morbid obese patients, 36 females and 32 males. The patients were with age range 24-56 years, BMI≥ 40 kg/m2or≥35 kg/m2 with co morbidities. Pulmonary volumes and function tests of all patients were measured before weight loss surgery and one year after the surgery. RESULT: The results showed a significant reduction in the body weight (p < 0.05), with an improvement in co morbidities. Pulmonary volumes ERV,IRV,TLC, FRC and RV were significantly changed one year after surgery as well as there were significant increases in the mean values of the dynamic volumes such as FEV1,FEV1%,FEF50%, PEF and MVV.(p < 0.05). CONCLUSION: loss of excess body weight by bariatric surgery resulted in a significant improvement in co morbidities and function of respiratory system represented by significant changes in both static and dynamic lung volumes .
RESUMEN
BACKGROUND: About 75%-85% of enterocutaneous fistulas are postoperative. Such fistulas are still disastrous and frustrating complication for surgeon and the patient and their management remains one of major challenge and dilemma in general surgical practice. Strict adherence to treatment guideline according to SOWATS protocol could results in better outcomes. THE OBJECTIVE: of this study was to assess the management outcomes of 23 patients with postoperative enterocutaneous fistulas. METHODS: A total of 23 consecutive patients with postoperative enterocutaneous fistulas during the period of study were included. These fistulas were classified anatomically and physiologically. The predictive factors for spontaneous closure, management outcomes and mortality rate factors for were studied. RESULTS: Overall Closure of the fistulas was accomplished in 16 patients (69.6%). Spontaneous closure after successful conservative management was seen in 4 patients (17.4%). The average time between fistula development and spontaneous closure was 32 days (range12-66 days). Of 19 patients underwent corrective surgery, closure was achieved in 12 patients (52.2%), thus the surgical success rate was 63.2%. Surgical intervention was performed after an average period of 28 days (range 18-42 days) from diagnosis of the fistula. Five patients with high output (21.7%) died because of sepsis, severe malnutrition and organ failure. CONCLUSION: adherence to standardized protocol and multidisciplinary approach of patients with enterocutaneous fistulas could results in good outcomes. A reasonable period of conservative treatment is always required to optimize patient's general conditions and for spontaneous closure of fistula. Operative correction is usually required for proximal high output and complex fistulas. The complexity of the fistulas, sepsis, high output effluent and comorbidities are the main factors affecting healing rates and fistula related mortality.
