Few topics in operative and perioperative patient management generate more controversy than that of appropriate fluid and electrolyte therapy. especially, controversy has swirled around colloid vs crystalloid therapy and the composition of administered fluids, agreement among clinicians as to what fluid therapy is appropriate, and in what amount, is rare. This controversy likely will be enhanced by Arieff' s provocative article. He described 11 adults and 2 pediatric patients. All developed fatal postoperative pulmonary edema, seemingly caused solely by excessive postoperative fluid administration. From January 1999 to December 1999, we investigated 24 patients, which were operated by orthognathic surgery, about the intraoperative fluid therapy and the associated effect in orthognathic surgery, which is regarded as one of the major surgery of oral and maxillofacial surgery. First, They were devided into two groups, that is one-jaw surgery and two-jaw surgery, and each groups were devided by intraoperative fluid volume of 8ml/kg/hr. Subjective assesment was collected through use of a series of 3 questionnaries. In each questionnaire, a 5-point Liekert scale was used far assessment of following parameters of recovery from anesthesia: headache, dizziness, drowsiness, nausea/vomiting, thirst. The patient completed questionnaire 1 at 4 hour after surgery, questionnaire 2 was completed at 24 hours after surgery, and questionnaire 3 was completed at 48 hours after surgery. This study demonstrated that appropriated perioperative rehydration decreases postoperative adverse outcomes and improved the patient's perception of the postoperative period.

Despite the major advances in the microvascular surgery with success rates of up to 98%, failure and vascular complications still remain even in the experienced hands. Failure of blood to flow across an anastomosis is usually caused by three factors: (1) Technical errors; (2) Undetected damage more proximally or via vasospasm; or (3) A clot or a thrombus. The success of a microvascular surgery depends on the severity of the vascular injury and, proper debridement of an injured vessel, and the failure rate of microvascular anastomosis in cases of trauma is higher as the thrombogenic possibility is increased by the endothelial damage. From January to November in 2003, 460 patients were underwent microvascular surgery(270 replantations and 190 free flap transfers) and re-operations were performed in 15 cases. Cases were reviewed by clinical and operative records. In these cases, causes of post-operative circulation insufficiency were identified as 9 vascular spasms and 6 thromboses at the previous anastomotic site. The average of re-operative success rate was 73%(60% in replantations and 100% in free flaps). In conclusion, through precise postoperative monitoring and assessment, immediate surgical re-exploration could be performed when a vascular complication is suspicious, the success rate of microvascular surgery would be increased more.

Background: This study provides an update to a landmark 2004 report describing demographics, training, and trends in adherence to thoracic surgery practice standards in Canada. Methods: An updated questionnaire was administered to all members of the Canadian Association of Thoracic Surgeons via email (n=142, compared to n=68 in 2004). Our report incorporates internal data from Ontario Health and the Canadian Partnership Against Cancer. Results: Forty-eight surgeons completed the survey (male, 70.8%; mean±standard deviation age, 50.3±9.3 years). This represents a 33.8% response rate, compared to 64.7% in 2004. Most surgeons (69%) served a patient population of over 1 million per center; 32%-34% reported an on-call ratio of 1:4-1:5 days, and the average weekly hours worked was 56.4±11.9. Greater access to dedicated geographic units per center (73% in 2021 vs. 53% in 2004) has improved thoracic-associated services and house staff, notably endoscopy units (100% vs. 91%), with 73% of respondents having access to both endobronchial and endoscopic ultrasound. Access to thoracic radiology has also improved, particularly regarding positron emission tomography scanners per center (76.9% vs. 13%). Annual case volumes for lung (255 vs. 128), esophageal (41 vs. 19), and mediastinal resections (30 vs. 13), along with hiatal hernia repair (45 vs. 20), have increased substantially despite reports of operating room availability and radiology as rate-limiting steps. Conclusion: This survey characterizes compliance with current practice standards, addressing the needs of thoracic surgeons across Canada. Over 85% of respondents were aware of the 2004 compliance paper, and 35% had applied for resources and equipment in response.

Brown syndrome is known as limited elevation of the affected eye during adduction. It is caused by a disorder of the superior oblique tendon, which makes it difficult for the eyeball to look upward, especially during adduction. It is classified into congenital true sheath Brown syndrome and acquired simulated Brown syndrome. Acquired simulated Brown syndrome can be caused by trauma, infection, or inflammatory conditions. The surgical restoration of blowout fractures can also lead to limitations of ocular motility, including Brown syndrome. We report on three patients with acquired simulated Brown syndrome, who complained of diplopia and limitation of ocular motility after operations to treat blowout fractures.

Primary intrapulmonary thymomas (PITs) are defined as thymomas arising in intrapulmonary locations, without an associated mediastinal component. They are rare lesions, the diagnosis of which can be very difficult. We present a case of PIT in an asymptomatic 74-year-old woman in whom pulmonary nodules were found on pulmonary angiography performed for an episode of pulmonary embolism. She underwent wedge resection and the pathology report revealed a PIT. We also summarize this patient's clinicopathological features and discuss the diagnosis, pathogenesis, and treatment of PIT.

Organized hematoma of maxillary sinus is a rare pathologically benign mass in which pressure in the hematoma increases as it undergoes a process of organization, causing the deformation of the surrounding tissue, mimicking malignancies. The midfacial degloving approach can be used when extensive exposure is required in the treatment of lesions or traumas in the midfacial area with intranasal and intraoral incisions. We report a surgical excision case of organized hematoma of maxillary sinus using midfacial degloving approach without major complications and recurrence after one-year follow up.

Gallstone ileus is an uncommon cause of intestinal obstruction. It may present with typical symptoms of intestinal obstruction with or without biliary sepsis. Its management strategies vary depending on the patient and operative factors. Enterotomy and stone removal alone versus synchronous cholecystectomy and fistula disconnection at the same stage, often pose a debate among surgeons. The decision for operative strategies largely depends on the surgeon's experience, patient's physiology, and operative difficulties. As literature on gall stone ileus remains insufficient at a regional level, we report four cases of gallstone ileus managed with different approaches. Three patients were managed in a staged-manner, whereas one patient received a definitive procedure performed at index surgery. Clinical challenges and associated operative strategies are discussed. Findings of the current study were compared to those of the literature. The need for a definitive fistula disconnection and repair or cholecystectomy following stone removal in these patients was subsequently discussed.

Traumatic rupture of the right hemidiaphragm occurred following a high-velocity motor vehicle collision in the case presented herein. The resulting herniation of small bowel loops into the thorax resulted in hemodynamic and respiratory compromise due to pressure effects on the right heart and major vessels. The patient's hemodynamic status improved with reduction of enterothorax, and the diaphragmatic defect was repaired. We discuss the available literature and learning points from this rare case.
