Achalasia is a motor disorder characterized by esophageal aperistalsis and failure of lower esophageal sphincter relaxation. The cardinal symptoms are dysphagia, food regurgitation and weight loss. The most effective treatments are pneumatic dilation (PD) of the cardia and Heller esophageal myotomy with partial fundoplication. There is still controversy regarding which treatments should be initially done. The aims of this study were to evaluate clinical response and the variables related to good results in both treatments. Ninety-two patients with achalasia diagnosed by esophageal manometry were randomized to receive either PD or laparoscopic Heller myotomy with partial fundoplication. After the procedure, patients were followed up clinically and submitted to esophageal manometry and pH monitoring. Three months after treatment, 73% of the patients from PD group and 84% of the surgery group had good results (P = 0.19). After 2 years of follow-up, 54% of the PD group and 60% of the surgery group (P = not significant) were symptom free. Variables related to a good response to PD were a 50% drop in lower esophageal sphincter pressure (LESP) or a LESP <10 mmHg after treatment. Patients over 40 years old with LESP ≤32 mmHg before treatment and a drop in LESP >50% after treatment significantly achieved better responses after surgical treatment when compared with PD. The reflux rate was significantly higher in the PD group (27.7%) compared with the surgery group (4.7%), P = 0.003. We concluded that surgical treatment and PD for achalasia are equally effective even after 2 years of follow-up. The choice of treatment for achalasia should be based on the following parameters: treatment availability, rate of good results, complication rates, variables related to good responses and also the patient's wish.
-Context -Barrett's esophagus (BE) is characterized by intestinal metaplasia in the distal esophagus and is classified as short-segment (<3 cm -SSBE) or long-segment (>3 cm -LSSBE). It is suggested that LSSBE is associated with more severe esophageal motor abnormalities and increased acid exposure time than SSBE. Objective -To evaluate the prevalence of esophageal manometriy abnormalities and acid exposure times in patients with SSBE and LSSBE. Methods -Barrett's esophagus patients identified by upper endoscopy and confirmed by histopathology were, retrospectively, reviewed and divided into two groups: SSBE and LSBE. Demographic data, symptom duration, prevalence of hiatal hernia, lower esophagus sphincter basal pressure, prevalence of esophageal body abnormalities and acid exposure times were evaluated. Average % total time pH<4 in SSBE 9.12, LSBE 17.27 (P<0.000); % time pH<4 upright in SSBE 11.91; LSBE 24.29 (P=0.003); % time pH<4 supine in SSBE 10.86, LSBE 33.26 (P = 0.000). Conclusion -There was no difference between the prevalence of motor disorders in patients with SSBE and LSSBE. Acid reflux in upright and supine positions was more intense in LSBE.
Transperineal exposure of the high portion of the vagina is limited. These limitations can be circumvented using ASTRA (anterior sagittal transrectal approach). We report the use of this surgical strategy for the treatment of a case of acquired vaginal atresia after posterior anorectoplasty due to anorectal malformation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
