Hypothermia Prevention During Surgery: Comparison Between Thermal Mattress And Thermal Blanket


This study aimed to compare the efficiency of the thermal blanket and thermal mattress in the prevention of hypothermia during surgery. Thirty-eight randomized patients were divided into two groups (G1 – thermal blanket and G2 - thermal mattress). The variables studied were: length of surgery, length of stay in the post-anesthetic care unit, period without using the device after thermal induction, transport time from the operating room to post-anesthetic care unit, intraoperative fluid infusion, surgery size, anesthetic technique, age, body mass index, esophageal, axillary and operating room temperature. In G2, length of surgery and starch infusion longer was higher (both p=0.03), but no hypothermia occurred. During the surgical anesthetic procedure, the axillary temperature was higher at 120 minutes (p=0.04), and esophageal temperature was higher at 120 (p=0.002) and 180 minutes (p=0.03) and at the end of the procedure (p=0.002). The thermal mattress was more effective in preventing hypothermia during surgery.

Bilateral Killian-Jamieson diverticula demonstrated by videofluoroscopic swallowing study: case report

The authors report the case of a 56-year-old male patient complaining of dysphagia for solids and food impaction, submitted to videofluoroscopic swallowing study that demonstrated the presence of two esophageal diverticula. The videofluoroscopic swallowing study was critical in the identification and diagnosis of the diverticula, an esophageal cause of dysphagia.

Validação de metodologia analítica por cromatografia líquida para doseamento e estudo da estabilidade de pantoprazol sódico

Pantoprazole is a proton pump inhibitor used in the treatment of digestive ulcers, gastro-esophageal reflux disease and in the eradication of Helicobacter pylori. In this work, an analytical method was developed and validated for the quantification of sodium pantoprazole by HPLC. The method was specific, linear, precise and exact. In order to verify the stability of pantoprazole during dissolution assays, pantoprazole solution in phosphate buffer pH 7.4 was kept at room temperature and protected from light for 22 days. Pantoprazole presented less than 5% of degradation in 6 hours and the half live of the degradation was 124 h.

Conduta terapêutica atual no adenocarcinoma da cárdia e da junção esofagogástrica

Adenocarcinomas of the cardia and gastroesophageal junction are peculiar entities with three different origins, which differ somewhat from other adenocarcinomas of the stomach in their clinical presentation and pathogenesis, and have a poorer prognosis. In this article the authors reviewed definitions, incidence and epidemiology, etiologic factors, genetic implications, clinical presentation, diagnosis, staging and treatment, with emphasis on the surgical approach, discussing the current management of these cancers. The prognostic factors related specifically to the cardia cancers are: esophageal invasion greater than 3cm, microscopic residual tumor and wall penetration (>T2). Preoperative workup should include computed tomography, and endoscopic ultrasonography and laparoscopy when available. Preoperative recognition of T3/ T4/N2 lesions should indicate inclusion in neo-adjuvant protocols whenever possible. The authors present the results of 46 resected cases of adenocarcinomas of the cardia and GE junction of the Instituto Nacional do Câncer- Brazil (1981-1995). Cure was intended in 29 and palliation in 17 patients. The most common type of resection was total gastrectomy with abdominal esophagectomy (28 cases). Morbidity (major and minor) occurred in 50% of the patients. The main causes were of respiratory origin and fistulas (19.6% each). Death occurred in 44% of the patients with fistula. Postoperative death until the 30th day occurred in 17.24% of the curative cases and in 23.52% of the palliative ones. The median survival time was 68.5 months for stage I, 25 months for stage II, 31 months for stage III and 12.5 months for stage IV diseases. The median survival time was 8 months for palliation and 28.5 months for cure. No long-term survival was obtained with the palliative group, whereas 25% survived five years of more in the curative group. The authors conclude that the surgical approach should be the one the surgeon feels more comfortable with. Complete removal of the disease proved by frozen section, splenectomy and D2 lymphadenectomy should be the standard therapy with curative intent.

Leiomioma do esôfago removido por videolaparoscopia

This report describes a leiomyoma of the inferior third section of the esophagus removed during laparoscopic cholecystectomy. The patient is a woman 55-years-age, carrying esophageal myoma of 40 mm in diameter wide, situated in the posterior wall of the lower esophagus. Indications for surgery were based mainly on the growth of the mass (6 mm when discovered 7 years previously, increased to 40 mm). Recently the patient returned suffering from pain, which could be attributed to his litiasic cholecystopaty. A small degree of low disphagia could also be observed. Radiologic imaging, direct endoscopic examination and endoscopic ultrasound showed that the mioma protruded on to the oesophagic lumen, discreetly diminishing there. A laparoscopic esophageal myomectomy was indicated at the same session of the laparoscopic cholecystectomy. Once the pneunoperitoneum was installed, five ports were placed as if for a hiatus hernia surgery. The cholecystectomy was uneventful. Next, an esophagoscopy was performed so as to determine the precise area covering the base of the tumour; at the right-lateral site. Longitudinal and circular fibres of the esophagus was severed over the lesion and the enucleation of the tumour was performed alternating the monopolar dissection, bipolar and hidrodisection. Control-endoscopy was carried out to verify mucosa integrity. Four suture points with poliglactine 3-0 string so as to close the musculature followed this. One suture was placed in for diminution of the size of the esophagean hiatus. Total time of intervention: two hours (30m for the cholecystectomy and one hour and thirty minutes for the myomectomy). Postoperative period: uneventful. Disappearance of the disphagia was observed. Radiologic transit control with water-soluble contrast at 4th post-operative day: good passage. Diagnosis from laboratory of pathology: conjunctive tumour formed by muscle non-striated cells: leiomyoma. The patient was re-examined on the two-month postoperative follow-up. General conditions were good and there were no complain of dysphagia. Neither there were any symptoms of gastro-esophageal reflux.

Diverticulo epifrênico do esôfago

Disphagia is a very common complaint among patients seeking a gastroenterologists. Esophageal motility disorder is a frequent finding, at times associated with pulsion diverticula. We present a case of a 68 year old female patient with thoracic pain and double epiphrenic diverticula. The upper gastrointestinal tract examination revealed two epiphrenic diverticula, one with 6-7 cm and the other measuring 2 cm, located 30 cm from the dental arcade. She underwent surgical treatment to remove the larger diverticula, a long esophageal myotomy and a Belsey-Mark IV antireflux technique. She presented an uneventful recovery and is doing well I8 months following surgery.

Leiomiomas do esôfago removidos por vídeo-toracoscopia

This report describes three cases of esophageal leiomyomas successfully resected by thoracoscopy. Surgical enucleation through minimally invasive surgery is the treatment of choice for esophageal leiomyoma. The conventional approach through a formal thoracotomy has the potential of causing excessive pain and patient discomfort. Moreover, the hospital stay and the recovery period are prolonged. Indications for surgery were based mainly on the size of the mass (<4 cm) and the presence of dysphagia. In one case there was a clear suspicion of malignancy. The tumour was located in the lower thoracic esophagus (case 1), in the middle thoracic esophagus (case 2) and in the upper esophagus (case 3). The CT was useful in identifying the relationship between the lesion and the organs of the mediastinum. The barium swallow study was able to locate the lesion along the esophagus. The endosonography determined the boundaries of the lesions. A right thoracoscopic approach was undertaken. Dissection of the esophagus around its entire perimeter was never necessary because all tumours were anterior or right sided. The tumours were better grasped with a traction suture than with forceps. The hidrodissection was very helpful. The water-soluble contrast swallow, performed on the fourth postoperative day, was normal. Clinical results were satisfactory in all patients. Biopsies should never be performed when the mucosa overlying is normal.

O uso do tubo colônico bipediculado microcirúrgico na reconstrução do esôfago

In some cases of esophageal reconstruction, it is not possible to use the gastric tube. In those cases, the second option is the reconstruction with a colonic segment. In the present paper, the authors present the use of microsurgical technique to improve vascular supply in esophageal reconstructions using the colon. Therefore, the transposed segment becomes perfused by two vascular pedicles: a proximal one and a distal one. The authors describe a case of 52 years-old patient, suffering of middle third esophagus carcinoma, who underwent a primarily esophageal resection with an unsuccessful reconstruction using gastric transposition. A new reconstruction was proposed using a bipedicle microcirurgical colonic tube, four months later. The post operative was uneventful with rehabilitation of swallowing and satisfactory recovery of nutritional state.

Nova técnica de alimentação enteral em fístulas esôfago-jejunais

BACKGROUND: A new procedure for the treatment of esophageal fistula, mainly associated to the ebb esophagojejunal in patients submitted to the total gastrectomy and reconstruction with loop jejunal Rouxen-Y anastomosis is present. METHODS: The method is based in the use of "probe standard enteral prolongated with drain to laminate adapted in extremity", which results in advanced positioning inside the jejunum, making the administration of enteral nutrition possible and impeding ebb esophagojejunal. RESULTS: The authors discuss the theoretical advantages of the procedure and they suggest that the treatment of esofagic fistula with probe prolonged enteral would be suitable in the treatment of the fistula esophagojejunal by preventing the ebb esophagojejunal, which would result in smaller period of duration of the fistula esophagojejunal and it would prevent the high mortality rate. CONCLUSIONS: Preliminary studies demonstrated that this is a technically easy, low cost procedure through the endoscopic use. A prospective evaluation for morbility and mortality related to the method is needed.

Leiomiossarcoma do esôfago

The authors describe a case of esophageal leiomyosarcoma treated at the Abdominopelvic Surgery Department of the Brazilian National Cancer Institute, including literature review, addressing treatment and prognosis. A 45 year-old female patient complaining of dysphagia, with pre-operative exams sugestive of esophageal leiomyoma. She was submitted to an esophagusgastrectomy with digestive reconstitution using a gastric tube brought through the posterior mediastinum. The histopathological examination and immunohistochemical tests confirmed that the tumor was an esophageal leiomyosarcoma. She is at the 7th year of follow up with no recurrence nor digestive complains.

Exérese de leiomioma esofágico por toracotomia

A 49yrs old, male patient presented progressive dysphagia during the last two years, initially to solids and, since two weeks, liquids he had lost 15 kilos. Esophagogram showed an intraluminal lesion with regular mucosa in the middle third of esophagus. The esophagoscopy exhibits regular mucosa up to the lesion, which did not alow passage. There was no evidence of linfonodal disease at CT scan. The hypothesis of esophageal leiomyoma led this patient a right posterior thoracotomy and enucleation of a 30 x 30 mm mass from the esophageal wall. With this case report we intend to review esophageal leiomyomas and their diagnosis and treatment.

Fístula esôfago-bronco-pleural pós pneumonectomia direita

We report the case of a 42 years old female that presented a simultaneous bronchial and esophagopleural fistula 32 months following a right pneumonectomy for pulmonary tuberculosis. The clinical findings were mainly related to pleural sepsis. The treatment consisted initially in clearing the pleural infection, followed by closure of both fistulae, using muscle flaps and thoracoplasty. The post operative course was uneventful and the patient is doing well over three years later.

Divertículo de Zenker: relato de três casos

Pharyngoesophageal diverticula are epithelial-lined pouches that protrude from the esophageal lumen. They were studied by Zenker in 1878,receiving the denomination of Zenker's diverticulum. They are false diverticula since they don't have all layers of the esophageal wall. Although they are most common esophageal diverticula . Their incidence is of 3% of the patient presenting dysphagia. Current , there are several therapeutic modalities, from dilatation of the esophagus to surgery with resection of the diverticulum. The report refers to three patients with Zenker's diverticulum who underwent conventional surgical treatment.

Tuberculose esofágica primária: relato de caso

Esophageal tuberculosis is an extremely rare event, accounting for 0.2 percent of these cases affecting the esophagus. Most of them are secondary to pulmonary disease. The authors present a case of primary esophageal tuberculosis in a 40 years old HIV-positive female.

Esofagectomia na perfuração esofágica com diagnóstico tardio

Esophageal perforations are related to high mortality rates, especially if there is a delayed diagnostic and treatment. We report an esophageal perforation caused by caustic ingestion, in a suicidal attempt, successfully treated by esophagectomy after a long period of misdiagnosis that lead to infectious complications.
