RESUMO
There is controversy in the literature regarding the motor function behavior of the lower esophageal sphincter and esophagus following partial gastrectomy. We studied 26 patients with gastric adenocarcinoma of the distal corpus and/or antrum who underwent radical subtotal gastrectomy with Roux-en-Y reconstruction. There were 15 women (57.69%) and 11 men (42.31%) with a mean age of 57.2 years; 21 were White (80.8%) and five were of African descent (19.2%). Before the surgery and 3 months afterwards, every patient underwent manometric and endoscopic examinations. The lower esophageal sphincter showed reductions in mean respiratory pressure (19.41-15.59 mmHg, P= 0.02) and maximum expiratory pressure (8.13-5.54 mmHg, P= 0.02) without significant alteration in diaphragmatic crura pressure (32.92-30.64 mmHg, P= 0.37). An increase in peristaltic wave amplitude (91.43-124.86 mmHg, P < 0.01) and peristaltic wave conduction velocity (3.29 cm/s to 4.23 cm/s; P= 0.024) were detected in esophageal function. The presence of erosive esophagitis decreased from 10 (38.46%) patients to none (P= 0.002). We concluded that following surgery the lower esophageal sphincter function was impaired, through decreased pressure in the esophageal component without alteration in diaphragmatic crura pressure. On the other hand, there was significant increase in peristaltic wave amplitude and velocity, and improvement of the erosive esophagitis. The authors suggest that subtotal gastrectomy, with gastroesophageal junction preservation, and Roux-en-Y reconstruction should be the preferred operation for distal gastric cancer to minimize esophageal dysfunction and gastroesophageal reflux disease.

The duration of hospital stay, following surgical procedures, has undergone a significant reduction in recent years. However, there are some risks associated with short-stay thyroid surgery. An analysis has been made of data from patients who underwent short-stay thyroid surgery, analyzing the complications associated with this procedure. Overall 270 consecutive patients undergoing thyroidectomy in 2007 and 2008 were prospectively analyzed. Post-operative care included routine ward overnight observation. The discharge criteria were: stable vital signs; apyretic; no wound or airway problems; tolerating diet; and established autonomy at discharge. Data were collected regarding patients' discharge criteria status, length of hospital stay and readmission, as well as morbidity (post-operative haemorrhage, recurrent laryngeal nerve injury and hypocalcaemia) and mortality. This series comprised 175 total thyroidectomies, 93 hemi-thyroidectomies and 2 isthmusectomies. No cases of death or post-operative haemorrhage occurred in any of these patients. Permanent unilateral recurrent laryngeal nerve injury was observed in 4 patients (1.48%). Transient post-operative hypocalcaemia occurred in 23 patients, whereas permanent post-operative hypocalcaemia was observed in 8 patients (2.96%); 4 patients were re-admitted and required early calcium supplementation. Five patients failed to tolerate the diet during the immediate post-operative period. The average duration of hospital stay was 1.02 days. Considering the 4 patients who required re-admission due to hypocalcaemia, the total length of hospital stay was 1.05 days. In conclusion, the one-day surgery model is safe and effective in patients undergoing surgery for thyroid disorders.

The assessment of depressive behaviour in chronic pain patients is especially important, because depression is commonly associated with chronic pain. The aim of this pilot study was to compare depression levels between patients with head and neck cancer pain and temporomandibular disorders (TMD), and to determine whether there is an association between depression levels and chronic pain severity. This study was an observational and sectional study and the sample consisted of 40 patients, uniformly divided into those with chronic orofacial pain related to cancer and those with painful TMD classified with research diagnostic criteria for temporomandibular disorders (RDC/TMD) axis I. Depression levels, pain intensity and severity were assessed with RDC/TMD axis II. The study demonstrated statistically significant differences in depression levels present in the head and neck cancer pain group and the painful TMD group, with the occurrence of a moderate statistically significant correlation between depression levels and chronic pain severity.
