Objective To investigate the clinical characteristics of 30-day unplanned reoperations after thoracic surgery. Methods We retrospectively analyzed the clinical data of patients with unplanned reoperations within 30 days after thoracic surgery in Peking Union Medical College Hospital from May 2016 to May 2021. Results The 30-day unplanned reoperations showed the incidence of 0.75%(79/10 543),the median hospital stay of 19(12,37) days,and the median hospitalization cost of 109 929.11(80 549.46,173 491.87) yuan.Twenty-two(27.85%) patients received blood transfusion and 26(32.91%) underwent intensive care.The period between May 2016 and May 2017 witnessed the most unplanned reoperations.The main causes of unplanned reoperations after thoracic surgery were bleeding(21.52%),chylothorax(17.72%),pulmonary air leakage(16.46%),atelectasis(13.92%),and gastroesophageal fistula(11.39%).Specifically,the main causes of unplanned reoperations in the patients of non-esophagus/cardia group were bleeding,pulmonary air leakage,atelectasis,and chylothorax,and those in the patients of esophagus/cardia group were gastroesophageal fistula,incision infection and poor healing,bleeding,and chylothorax.Among all the patients with unplanned reoperations,4 patients died,17 improved,and 58 recovered. Conclusions The patients who underwent unplanned reoperations after thoracic surgery had a long hospital stay and high hospitalization costs. Bleeding,chylothorax,pulmonary air leakage,atelectasis,and gastroesophageal fistula were the main reasons for the unplanned reoperations.

BACKGROUND: Computed tomography (CT) three-dimensional reconstruction technology is increasingly used in preoperative planning of patients with ground glass nodule (GGN), but how to accurately locate the nodule and ensure the safe resection edge is still a difficult problem for clinicians. The purpose of this study was to investigate the accuracy, convenience and safety of CT three-dimensional reconstruction combined with intraoperative natural collapse localization in total thoracoscopic segmental pneumonectomy. METHODS: A total of 45 patients with radiographic findings of pulmonary GGN admitted from July 2019 to December 2019 were selected as the study group. All patients received thin-slice CT scan and underwent preoperative three-dimensional reconstruction. After anesthesia, the small thoracic operation opening and the airway of the patients were quickly opened, and the lung was rapidly and naturally collapsed by pressure difference. GGN were positioned according to the natural marker line, and marked with 3-0 prolene line. After specimen removal, the distance between the GGN and the suture mark, the distance between the GGN and the incision margin were measured, and the incision margin was routinely examined. The general clinical data, pathological data and postoperative complications were counted and compared with 45 consecutive patients who were located with hookwire positioning needle in the same period. RESULTS: The average localization time of non-invasive GGN with natural lung collapse during operation was 6.9 min, and the localization accuracy was 90.6%. There were 2 cases of extensive pleural adhesion and 1 case of emphysema. Postoperative pathology was confirmed as lung adenocarcinoma, and the examination of incision margin was negative. No GGNs were scanned again after surgery, and the precise resection rate of lung segment was 100.0%. CONCLUSIONS CT three-dimensional reconstruction combined with GGN localization of natural lung collapse during operation can shorten the time of searching for GGN during operation and guarantee the safety of the incision margin. It is a more economical and convenient localization method and makes pulmonary segment resection more accurate.

OBJECTIVE: To investigate the risk factors of postoperative pulmonary infection (PPI) in patients over 60 years of age with gastric cancer after radical gastrectomy. METHODS: Clinicopathological data of 373 patients over 60 years of age who underwent radical gastrectomy at Department IV of Gastrointestinal Cancer Center, Peking University Cancer Hospital, from April 2009 to December 2016 were retrospectively collected in this case-control study. The clinicopathological characteristics of patients with postoperative pulmonary infection (including postoperative atelectasis) and those without pulmonary infection were compared. A Student t-test (reported as Mean±SD if data matching normal distribution) or Mann-Whitney U test [reported as median (quartile) if data did not conform to normal distribution] was used to analyze continuous variables. A χ² test or Fisher exact tests (reported as number and percentage) was used for categorical variables. Multivariable logistic regression was used to analyze the risk factors for pulmonary infection after operation of gastric cancer.PPI was defined as postoperative patients with elevated body temperature (>38.0 degrees centigrade) for more than 24 hours; cough and expectoration; positive sputum bacteria culture;recent infiltration, consolidation or atelectasis confirmed by chest imaging examination. RESULTS: Among 373 patients, 50 cases had PPI(13.4%, PPI group), 323 cases had no PPI(86.6%, non-PPI group). There were 39 (78.0%) and 178(55.1%) patients with comorbidities (including hypertension, diabetes and cardiopulmonary disease) preoperatively in PPI and non-PPI group, respectively. The difference between two groups was statistically significant (χ²=9.325,P=0.002). The incidence of preoperative hypoalbuminemia in PPI group was also significantly higher than that in non-PPI group [10.0%(5/50) vs. 3.1% (10/323),χ²=4.098, P=0.048]. Compared to non-PPI group, the rate of total gastrectomy [54.0%(27/50) vs. 34.4% (111/323), χ²=12.501, P=0.002], postoperative wound pain [34.0%(17/50) vs. 11.8% (38/323),χ²=16.928, P<0.001], secondary operation [6.0%(3/50) vs. 0.6% (2/323), χ²=6.032, P=0.014] and the rate of gastric tube removal later than 7 days postoperatively [96.0%(48/50) vs. 84.5%(273/323),χ²=4.811, P=0.028] were significantly higher in PPI group, respectively. The postoperative hospital stay was also prolonged in PPI group [16.0(9.5) days vs. 12.0(5.0) days, U=4 275.0, P<0.001]. Multivariate logistic regression analysis showed that preoperative comorbidities (OR=4.008, 95%CI:1.768-9.086, P=0.001), abdominal infection (OR=3.164, 95%CI:1.075-9.313, P=0.037), and wound pain (OR=3.428, 95%CI:1.557-7.548, P=0.002) were independent risk factors for PPI in patients over 60 years of age with gastric cancer. Furthermore, 50 patients with pulmonary infection were classified according to the length of latency and the type of infection. The patients with PPI latency ≤ 3 days were classified as early onset (34 cases, 68.0%), and those with latency ≥ 4 days as delayed onset (16 cases, 32.0%); PPI combined with surgical infection (including anastomotic leakage, abdominal infection, duodenal stump leakage, wound infection, etc.) was classified into mixed infection group (13 cases, 26.0%), with non-surgical infection as simple infection group (37 cases, 74.0%). The results showed that the pulmonary infection occurred 0 to 12 days (median 3 days) before surgical infection in mix infection group. The incidence of previous chronic obstructive pulmonary disease (COPD) in patients with early onset was significantly higher than that in patients with delayed onset [17.6%(6/34) vs. 0, χ²=5.005, P=0.025], and the incidence of mixed infection in patients with delayed onset was significantly higher than that in patients with early onset [50%(8/16) vs. 14.7%(5/34), χ²=6.730, P=0.009],but there was no significant difference in postoperative hospital stay between the two groups[17.0(9.8) days vs. 14.0(9.5) days, U=224.0, P=0.317]. CONCLUSIONS Postoperative pulmonary infection is common in gastric cancer patients over 60 years of age. Preoperative comorbidities, abdominal infection and wound pain are independent risk factors for postoperative pulmonary infection. Pulmonary infection within 3 days after operation is associated with preoperative COPD. For patients suffering from PPI after the 4th day,attentions should be paid to abdominal infection and anastomotic leakage.

PURPOSE: Despite the use of different surgical methods, surgical site infection is still an important cause of mortality and morbidity in patients and imposes a considerable cost on the healthcare system. Administration of supplemental oxygen during surgery has been reported to reduce surgical site infection (SSI); however, that result is still controversial. This study was performed to evaluate the effect of hyperoxygenation during colorectal surgery on the incidence of wound infection. METHODS: This study was a prospective double-blind case-control study. The main aim of the study was to evaluate the effect of hyperoxygenation during colorectal surgery on the incidence of SSI. Also, secondary outcomes, such as atelectasis, pneumonia, respiratory failure, length of hospital stay, and required hospitalization in the intensive care unit were evaluated. RESULTS: SSI was recorded in 2 patients (2 of 40, 5%) in the hyperoxygenation group (FiO2 80%) and 6 patients (6 of 40, 15%) in the control group (FiO2 30%) (P < 0.05). Time of hospitalization was 6 ± 6.4 days in the hyperoxygenation group and 9.2 ± 2.4 days in the control group (P < 0.05). CONCLUSION: This study showed a positive effect of hyperoxygenation in reducing SSI in colorectal surgery, especially surgery in an emergency setting. When the low risk, low cost, and effectiveness of this method in patients undergoing a laparotomy are considered, it is recommended for all patients undergoing colorectal surgery.

Patients undergoing thoracic surgery show various lesions such as chronic obstructive lung diseases, pleural adhesion, pneumonia, acute respiratory distress syndrome, atelectasis, pleural effusion, pulmonary edema, and pneumothorax throughout preoperative, operative, and recovery periods. Therefore, lung ultrasonography has potential for perioperative use in thoracic surgery. Benefits of lung ultrasonography over conventional chest X-ray are convincing. First, ultrasonography has higher sensitivity than X-ray in various lesions. Second, it can be performed at bed side to obtain diagnosis immediately. Third, it does not expose patients to radiologic hazard. If anesthesiologists can obtain necessary skills and perform lung ultrasonography as a routine evaluation process for patients, territory of anesthesia would become broader and patients would obtain more benefit.

PURPOSE: Our aim for this study was to evaluate early and late complications and outcomes of primary sleeve gastrectomy (PSG) versus conversion sleeve gastrectomy (CSG). METHODS: From February 2013 to December 2016, a total of 180 patients underwent sleeve gastrectomy (150 PSG and 30 CSG). All patients received a metal clipping at the end of the stapling line and a continuous seromuscular suture at the resection margin, for reinforcement. RESULTS: There were no differences in the percentages among males and females or age between the 2 groups, but the body mass index (BMI) of the PSG group was higher at 36.8 ± 4.7 than that of the CSG group (32.4 ± 5.7, P < 0.001). Three early postoperative complications were noted in the PSG group; 1 patient underwent repeat laparoscopic exploration due to pancreatic injury, and 2 other patients developed pulmonary atelectasis. On the contrary, 2 early minor complications were noted in the CSG group. Thirty-eight patients (25.3%) in the PSG group developed 43 late, minor complications, while 9 patients (30.0%) developed 11 late minor and 1 major complication in the CSG group. However, there was no difference in complication rate between PSG and CSG. Percentage excess BMI loss at 3, 6, and 12 months after surgery was comparable between the groups. CONCLUSION: PSG and CSG were comparable in terms of postoperative complications and loss of weight. Therefore, CSG could be used for failed primary restrictive bariatric surgery. However, the durability of these outcomes remains unknown.

The purpose of this study was to report and discuss the diagnosis and treatment of obstructive atelectasis secondary to pus obstruction in a patient who had developed a maxillofacial abscess, and to review the literature on similar cases. Persistently discharging pus within the oral cavity can act as an aspirate, and may lead to obstructive atelectasis. Additionally, maxillofacial surgery patients should be carefully assessed for the presence of risk factors of obstructive atelectasis, such as, epistaxis after nasotracheal intubation, oral bleeding, and mucus secretion. Furthermore, patients with these risk factors should be continuously followed up by monitoring SPO₂, breath sounds, and chest x-ray.

BACKGROUND: This study aimed to retrospectively evaluate the use of sugammadex in patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy. METHODS: Data were obtained from medical record review of patients who underwent VATS lobectomy from January 2013 to November 2014. Fifty patients were divided into two groups: the sugammadex group (group S, n = 19) was administered sugammadex 2 mg/kg, while the pyridostigmine group (group P, n = 31) received pyridostigmine 20 mg with glycopyrrolate 0.2 mg or atropine 0.5 mg. The primary endpoint measure was the overall incidence of postoperative pulmonary complications including prolonged air leak, pneumonia, and atelectasis. The secondary endpoint measures were the length of postoperative hospital stay and duration of chest tube insertion. RESULTS: The overall incidence of postoperative pulmonary complications in patients in group S was significantly lower compared with that of group P (5 [26.3%] vs. 17 [54.8%]; P = 0.049). Also, the durations of chest tube insertion (5.0 [4.0–7.0] vs. 7.0 [6.0–8.0] days; P = 0.014) and postoperative hospital stay (8.0 [8.0–10.0] vs. 10.0 [9.0–11.0] days; P = 0.019) were shorter in group S compared with group P. Administration of sugammadex was associated reduced with postoperative pulmonary complications (OR: 0.22; 95% CI: 0.05–0.87; P = 0.031). CONCLUSIONS: The use of sugammadex, compared with pyridostigmine, showed a significantly reduced overall incidence of postoperative pulmonary complications and decreased duration of chest tube use and postoperative hospital stay in patients undergoing VATS lobectomy, suggesting that sugammadex might be helpful in improving clinical outcomes in such patients.

OBJECTIVE: This study was conducted to assess the surgical results of one-stage posterior minimal laminectomy and video-assisted thoracoscopic surgery (VATS) for the treatment of thoracic dumbbell tumor and to describe its precise technique. In addition, we investigated the technique's usefulness and limitations. METHODS: Seven cases of thoracic dumbbell tumor (two men and five women, mean age, 43 years) were analyzed retrospectively. Pathological findings included schwannoma in four patients, neurofibroma in two patients, and hemangioma in one patient. The location of tumors varied from T2/3 to T12/L1. Dumbbell tumors were resected by one-stage operation using posterior laminectomy followed by VATS without instrumentation. Clinical data were reviewed. RESULTS: The mean follow-up period was 25 months (range, 3–58 months), and the operative time ranged from 255 to 385 min (mean, 331 min), with estimated blood loss ranging from 110 to 930 mL (mean, 348 mL). The tumor was completely resected without instrumentation and postoperative instability in all cases. Postoperative complications included atelectasis and facial anhydrosis in one case each. CONCLUSION: One-stage posterior minimal laminectomy and VATS may be a safe and less invasive technique for removal of thoracic dumbbell tumor without instability. This method has the advantage of early ambulation and rapid recovery because it reduces blood loss and postoperative pain.

A 76-year-old male underwent a left upper lobectomy with wedge resection of the superior segment of the left lower lobe using video-assisted thoracoscopic surgery (VATS) for non-small-cell lung cancer of the left upper lobe. He presented with shortness of breath, fever, and leukocytosis. Chest radiography showed atelectasis at the remaining left lower lobe. Bronchoscopy revealed narrowing of the left lower bronchus with purulent secretion, and computed tomography showed downward kinking of the left lower lobar bronchus. He underwent exploratory VATS, and intraoperative findings showed an inferiorly kinked left lower lobar bronchus with upward displacement of the left lower lobe. After adhesiolysis, the kinked bronchus was straightened, and bronchopexy was performed to the pericardium to prevent the recurrence of bronchial kinking. Also, the inferior pulmonary ligament was reattached to prevent upward displacement. Postoperative follow-up bronchoscopy revealed no evidence of residual bronchial obstruction, and chest radiography showed no atelectasis thereafter.
