RESUMEN

BACKGROUND: Pharyngoesophageal strictures (PES) after corrosive injury impose a problematic condition for both physicians and patients in terms of their management and patients' quality of life. Colopharyngoplasty is a complex procedure, which is used to restore swallowing in these severely disabled patients. We describe our experience in treating nine patients with severe PES after corrosive injuries in a referral center. MATERIALS AND METHODS: A retrospective analysis of our database from 2009 to 2014 showed nine patients (seven men; age range: 18 to 47 years) with severe PES who underwent colopharyngoplasty ∼6 months (range: 4-10) after caustic material ingestion. All patients had a feeding jejunostomy tube before reconstruction. Esophagectomy with or without gastrectomy was performed in all patients, except for one; thereafter, an isoperistaltic segment of the left colon was pulled up, and a pharyngocolic anastomosis was performed. Eight patients had a tracheostomy created either before reconstruction due to respiratory symptoms or at the time of definitive surgery to prevent aspiration in the early post-operative period. RESULTS: Almost all survivors had a satisfactory swallowing at the end of the follow-up (range: 4-60 months). The jejunostomy tube could be removed in all of the patients after a median of 5 months. One patient died of sepsis due to graft necrosis in the immediate post-operative period. Another patient died 5 months after the first surgery following a revision surgery for intractable dysphagia. At the end of the follow-up, only one patient tolerated tracheostomy tube decannulation. Two patients required laryngotracheal dissociation because of massive aspiration and recurrent episodes of pneumonia. Five patients still had a tracheostomy because of an severely destroyed larynx (two patients) and aspiration (three patients). CONCLUSION: Colopharyngoplasty is considered a complicated but trustworthy procedure to restore gastrointestinal tract continuity after severe corrosive injury. Undeniably, laryngeal involvement adversely affects the functional outcome. The post-operative course is frequently protracted, accompanied with several problems. Aspiration is nearly the most problematic event in the early post-operative period, which mandates a multidisciplinary approach to manage it.

RESUMEN

BACKGROUND: Heart size is an important and effective parameter in chest X-ray (CXR) interpretation. Studies indicate that, especially in middle-aged men, increased cardiothoracic ratio (CTR) is associated with ischemic heart disease (IHD) and increased rate of morbidity and mortality. The CXR is the most common imaging examination of the heart. OBJECTIVES: A good quality posterior-anterior (PA) chest radiograph is an important indicator of the cardiac size. Nowadays, CXR has given its place to more advanced approaches such as two-dimensional echocardiography. However, CXR is still more accessible and feasible for most of the physicians. This study was designed to compare the findings of CXR and echocardiography in determination of the heart size. PATIENTS AND METHODS: This cross-sectional study was carried out from 2006 to 2007. A total of 197 patients entered the study. The cases had been undergone PA CXR and 2-D echocardiography maximum within two days. RESULTS: Of participants, 24.9% had cardiomegaly according to the findings of CXR and 50.8% based on echocardiography. There was a statistically significant difference between the mean size of Right Ventricular End Diastolic Diameter in the patients with cardiothoracic ratio < 50% and ≥ 50% (P = 0.002) as well as Left Ventricular End Diastolic Diameter (P = 0.023). Also, a statistically significant difference was seen between echocardiography and CXR findings with regard to determination of the heart size (P = 0.003). Nonetheless, it is noteworthy that sensitivity and specificity of CXR findings in the diagnosis of cardiomegaly were 34%, and 84.5%, respectively. CONCLUSIONS: CTR is the most common method of describing the heart size. Increased CTR in CXR is associated with poor prognosis, which is suggestive of importance and necessity of early diagnosis. Although CXR may not have the same diagnostic accuracy as echocardiography, its easy accessibility and high specificity in diagnosis of cardiomegaly is very helpful, which can play an important and a cost-benefit role, particularly in screening the enlarged heart size. Moreover, according to the statistics released by Medical Council of Iran, most of Iranian physicians are general practitioners and a few of them are cardiologist.

RESUMEN

Carcinoid tumors comprise an uncommon group of pulmonary neoplasms with neuroendocrine origin. In comparison with typical carcinoid tumors, atypical tumors are less common and more aggressive. We present a 35-year old female with atypical carcinoid tumor. The mass was located centrally and transsternal pneumonectomy was performed to resect the tumor.
