Background: Few studies have evaluated the long-term impact of postoperative infectious complications in patients with non-small cell lung cancer (NSCLC). We aimed to determine the impact of infectious complications on long-term outcomes after surgical resection for NSCLC. Methods: We performed a retrospective study of 1,380 eligible patients who underwent pulmonary resection for NSCLC from 2003 to 2012. Complications were divided into infectious complications and non-infectious complications. Kaplan-Meier survival analysis was used to compare unadjusted 5-year cancer-specific survival (CSS) rates and recurrence-free survival (RFS) rates. Cox regression was used to determine the impact of infectious complications on 5-year CSS and RFS. Results: The rate of total complications and infectious complications was 24.3% and 4.3%, respectively. In the node-negative subgroup, the 5-year CSS and RFS rates were 75.9% and 57.1% in patients who had infectious complications, compared to 87.9% and 78.4% in patients who had no complications. Infectious complications were a negative prognostic factor for 5-year RFS (hazard ratio, 1.92; 95% confidence interval, 1.00-3.69; p=0.049). In the node-positive subgroup, the 5-year CSS rate and RFS were 44.6% and 48.4% in patients who had infectious complications, compared to 70.5% and 48.4% for patients who had no complications. Conclusion: Postoperative infectious complications had a negative impact on CSS and RFS in node-negative NSCLC. Our findings may help improve risk assessment for tumor recurrence after pulmonary resection for node-negative NSCLC.

Purpose: Minimally invasive gastrectomy is a promising surgical method with well-known benefits, including reduced postoperative complications. However, for total gastrectomy of gastric cancers, this approach does not significantly reduce the risk of complications. Therefore, we aimed to evaluate the incidence and risk factors for the severity of complications associated with minimally invasive total gastrectomy for gastric cancer. Materials and Methods: The study included 392 consecutive patients with gastric cancer who underwent either laparoscopic or robotic total gastrectomy between 2011 and 2019. Clinicopathological and operative characteristics were assessed to determine the features related to postoperative complications after minimally invasive total gastrectomy. Binomial and multinomial logistic regression models were used to identify the risk factors for overall complications and mild and severe complications, respectively. Results: Of 103 (26.3%) patients experiencing complications, 66 (16.8%) and 37 (9.4%) developed mild and severe complications, respectively. On multivariate multinomial regression analysis, independent predictors of severe complications included obesity (OR, 2.56; 95% CI, 1.02-6.43; P=0.046), advanced stage (OR, 2.90; 95% CI, 1.13-7.43; P=0.026), and more intraoperative bleeding (OR, 1.04; 95% CI, 1.02-1.06; P=0.001). Operation time was the only independent risk factor for mild complications (OR, 1.06; 95% CI, 1.001-1.13; P=0.047). Conclusions: The risk factors for mild and severe complications were associated with surgery, indicating surgical difficulty. Surgeons should be aware of these potential risks that are related to the severity of complications so as to reduce surgery-related complications after minimally invasive total gastrectomy for gastric cancer.

Background Cleft treatment is frequently performed in Indonesia, mostly in charity missions, but without a postoperative protocol it is difficult to establish the risks and complications of cleft treatment. The present study was designed to give an overview of current cleft lip and palate treatment strategies in Indonesia and to assess the complication rates during and after surgery. Methods This prospective study evaluated anesthetic, intraoperative surgical, and short-term postoperative complications in patients undergoing primary, secondary, or corrective surgery for cleft lip and palate deformities. The population consisted of 98 non-syndromic cleft patients. The main anesthetic complication that occurred during general anesthesia was high blood pressure, whereas the main intraoperative surgical complication was excessive bleeding and the main early postoperative complication was extremely poor wound hygiene. Results In this study, there were no cases of perioperative or postoperative mortality. However, in 23 (23.4%) of the 98 operations performed, at least one perioperative complication related to anesthesia occurred. The intraoperative and early postoperative complications following cleft lip and/or palate were assessed. There was a significant difference in the complication rate between procedure types (χ²=0.02; P<0.05). However, no relationship was found between perioperative complications related to anesthesia and the occurrence of postoperative complications (χ²=1.00; P>0.05). Nonetheless, a significant difference was found between procedure types regarding perioperative complications and the occurrence of postoperative complications (χ²=0.031; P<0.05). Conclusions Further evaluation of these outcomes would help direct patient management toward decreasing the complication rate.

Objectives: The aim of this study was to evaluate the implication of third molars in postoperative complications of mandibular angle fracture with open reduction and internal fixation (ORIF). Materials and Methods: Data were collected on patients who presented with mandibular angle fracture at our Department of Oral and Maxillofacial Surgery between January 2011 and December 2015. Of the 63 total patients who underwent ORIF and perioperative intermaxillary fixation (IMF) with an arch bar, 49 patients were identified as having third molars in the fracture line and were followed up with until plate removal. The complications of postoperative infection, postoperative nerve injury, bone healing, and changes in occlusion and temporomandibular joint were evaluated and analyzed using statistical methods. Results: In total, 49 patients had third molars in the fracture line and underwent ORIF surgery and perioperative IMF with an arch bar. The third molar in the fracture line was retained during ORIF in 39 patients. Several patients complained of nerve injury, temporomandibular disorder (TMD), change of occlusion, and postoperative infection around the retained third molar. The third molars were removed during ORIF surgery in 10 patients. Some of these patients complained of nerve injury, but no other complications, such as TMD, change in occlusion, or postoperative infection, were observed. There was no delayed union or nonunion in either of the groups. No statistically significant difference was found between the non-extraction group and the retained teeth group regarding complications after ORIF. Conclusion: If the third molar is partially impacted or completely nonfunctional, likely to be involved in pathologic conditions later in life, or possible to remove with the plate simultaneously, extraction of the third molar in the fracture line should be considered during ORIF surgery of the mandible angle fracture.

The diagnosis of the main complications resulting from lipoabdominoplasty has not yet been standardized. Infrared thermal imaging has been used to assess possible complications, such as necrosis and changes in micro- and macro-circulation, based on perforator mapping techniques, among others. The objective of this study was to present two clinical cases involving thermal imaging monitoring of the healing process of lipoabdominoplasty in the immediate postoperative evaluation and its preliminary results. Infrared thermography was performed 24 hours after the operation and on postoperative days 5, 25, and 27. In clinical case 1, it was found that the delta-R (∆T_R)-defined as the difference in minimum temperature between the highest and lowest points in the SA3 region (caution suction area) following the classification established by Matarasso-was 0.4℃ at 24 hours after surgery and decreased to 0.1℃ on a postoperative day 5. There were no complications in this case. In contrast, in clinical case 2, the ∆T_R was 1.7℃ at 24 hours after surgery (upon hospital discharge) and remained high, at 2.2℃, on postoperative day 5. A higher ∆T_R was found in the second patient, who developed necrosis of the surgical wound. The ∆T_R thermal index may be a new tool for predicting possible complications, complementing the clinical evaluation and therapeutic decision-making.

Since the first successful lung transplantation in 1983, there have been many advances in the field. Nevertheless, the latest data from the International Society for Heart and Lung Transplantation revealed that the risk of death from transplantation is 9%. Various aspects of postoperative management, including mechanical ventilation, could affect intensive care unit stay, hospital stay, and immediate postoperative morbidity and mortality. Complications such as reperfusion injury, graft rejection, infection, and dehiscence of anastomosis increase fatal adverse side effects immediately after surgery. In this article, we review the possible immediate complications after lung transplantation and summarize current knowledge on prevention and treatment.

This study evaluated retrospectively the treatment method and postoperative complications of communited mandibular fractures. We analyzed the clinical and radiologic data of 14 patients with the comminuted mandibular fractures who were admitted to Chosun University Dental Hospital from January 1998 to December 2003. We reviewed the cause of trauma, fracture sites, treatment methods, and postoperative complications. Thirteen patients (93%) had a successful treatment outcome without complications. Only one patient developed postoperative osteomyelitis requiring early plate removal and sequestrectomy. For the comminuted fractures of mandible, internal fixation using micro- or mini-plate was an effective treatment method with a low incidence of major complications.

During the last 10 years of period, one hundred patients with various pulmonary diseases were pneumonectomized upon at the Department of Chest Surgery of Pusan University Hospital. This paper is concerned with the clnical results of these patients along with the serious postoperative complications such as postoperative intrapleural infection and hemorrhage. The results were obtained as follows. 1.Left pneumonectomy was done in sixty-six of 100 patients [66 %] and the right one was done in the rest thirty-four[34 %]. The ratio between left and right was nearly 2:1. 2.Of all oostoperative complications, the intrapleural infection was most common, and these were 53 % in empyema thoracis and 12.7 % in pulmonary tuberculosis respectively. 3.More postoperative complications could be seen after right pneumonectomy than the left one. 4.It was thought that the postoperative intrapleural infection was closely correlated with the methods of pleural dissection at pneumonectomy,postoperatlve tube drainage, time of operation, massive hemorrhage during operation, prolongation of bleeding time, and dysfunction of the liver. 5.The repeated thoracenteses with infusion of neomycin into the infected thoracic cavity and intravenous administrations of the high units of penicillin were effective in treatment of the postoperative intrapleural infection, however, the refractory cases have to be cured by thoracoplasty with open window. 6.Immediate secondary open thoracotomy appears to be the method of choice in life saving who developed massive intrathoracic hemorrhage after pneumonectomy. 7.The mortality rate was 10 % in our cases and the main causes of death were postoperative respiratory insufficiency, pulmonary edema, hemorrhage and sudden cardiac arrest.

The goal of surgical correction for hallux valgus is to achieve a painless, shoe-wearable, and relatively straight toe with a balanced joint motion that results in aesthetically and functionally satisfactory toe. To date, there has not been a consensus on the ultimate surgical procedure for hallux valgus correction. Unfortunately, such a consensus may be difficult since it is not uncommon to encounter complications after hallux valgus correction. Postoperative soft tissue complications include difficult wound healing, infection, hypertrophy, or pain of the scar, joint stiffness, and tendon or sensory nerve damage. Postoperative bony complications include malunion, nonunion, failure of fixation, failure of angle correction, recurred deformity, osteomyelitis, and failure of balance between the metatarsal heads. Herein, we review common complications after surgical correction of hallux valgus, such as stiff joint, bony complications, recurrence of the deformity, and hallux varus.

Background: Intraoperative and postoperative ocular complications are rare. We retrospectively investigated the abnormal ocular findings in patients who underwent arthroscopic shoulder surgery. Methods: The records were investigated of patients who underwent shoulder arthroscopic surgery at our hospital between January 2018 and March 2019. Ocular complications were confirmed by review of medical records. We performed logistic regression analysis to defined the main factors associated with ocular complications. Results: The overall prevalence of postoperative ocular complications was 8.5% (18/211). A significant association was found between anti-adhesion barrier agent and ocular complications (p=0.020). Conclusions: Anti-adhesion barrier agent used during surgery may be the cause of postoperative ocular complication.
