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: Univent tube(endotracheal tube with a movable blocker), introduced by Inoue et al in 1982, has properties to overcome the disadvantages of double lumen endotracheal tube for one lung anesthesia. This study was performed to evaluate the effectiveness of Univent tube for one lung ventilation. METHODS: Univent tube was inserted to the patients for open thoracic surgery and positioned to the side of bronchus under the guidance of fiberoptic bronchoscope that was scheduled to lung collapse. One lung anesthesia was performed with the inflation of cuff of blocker. Each case was anaylzed with respect to ease or difficulty of positioning of blocker, tube displacement, efficacy of lung collapse and adequacy of single lung ventilation. RESULTS: In the 69 patients out of 80 patients, adequate positioning was performed by first trial. In the two patients, insertion of bronchial blocker was failed that resulted in replacement with a double lumen tube. Observed disadvantages were delayed deflation(10 patients) of affected lung and displacement of bronchial cuff into the main tracheal lumen during position change or surgical manipulation(7 patients). CONCLUSIONS: Univent tube is useful for one lung anesthesia but there are several distinct limitaitons in the safe use.

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.

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.

PURPOSE: This study was performed to assess the complications and discomfort of patients with or without a nasogastric tube who underwent elective colorectal surgery and to evaluate the efficacy of the routine practice of employing a nasogastric tube after elective colorectal surgery. METHODS: This study involved a prospective, randomized trial of 100 patients undergoing elective colorectal surgery from February to July 2004. The patients were classified as the nasogastric tube inserted group (NG (+), n=50) and non-inserted group (NG (-), n=50). The inclusion criteria were elective colorectal surgery, age under 70 years and no previous abdominal surgery history. The exclusion criteria were an emergent operation, an overt preoperative bowel obstruction and extensive operations such as pouch surgery and multivisceral resection. RESULTS: The mean age of the subjects was 55 (24~70) years old. There was no difference in terms of age, gender, pathological diagnosis and surgical procedures between the NG (-) and NG (+) groups. A sore throat and nausea was more prevalent in the NG (+) group (P=0.000, P=0.046). The gas passage time was shorter in the NG (-) group than in the NG (+) group (P=0.028). The other variables, such as vomiting, postoperative ileus, postoperative fever, posto-perative atelectasis, postoperative leakage, intraoperativedecompression, stool passage time and the length of the hospital stay revealed no difference between the groups. CONCLUSION: Nasogastric intubation is an uncomfortable procedure for patients and offers no benefit in preventing postoperatve complications. The routine use of a nasogastric tube is not necessary in elective colorectal surgery.

BACKGROUND: Complicated pleural space occupying lesions (SOL) have been treated by thoracentesis, closed thoracotomy drainage (CTD) or surgical intervention with using a video thoracosocpe or open thoracotomy depending on the extent of the disease. With the development of video assisted thoracoscopic surgery (VATS), VATS pleural adhesiolysis and decortication have revealed good results as compared to those for open thorcotomy. To assess the effectiveness of VATS pleural adhesiolysis and decortication, we retrospectively analyzed the medical record and radiologic findings of the patients with complicated pleural SOL and who were treated by this surgery. MATERIAL AND METHOD: From May 1996 to April 2006, 64 patients (mean age: 41.8 years) with complicated pleural SOL underwent 65 VATS. To analyze the surgical outcome, we classified the postoperative findings on the simple chest X-rays into 4 classes as Class I: no or minimal pleural lesion, Class II: blunting of the cardiophrenic angle and mild pleural thickening, Class III: an elevated diaphgram or persistent lung collapse and Class IV: complicated or recurrent effusion. RESULT: Before VATS, the patients underwent the diagnostic or therapeutic procedures: single or repeat diagnostic tapping for 41, thoracoscotomy drainage for 11, pigtail catheter drainage for 10 and intrapleural fibrinolytics for 10. The mean duration between the onset of symptom and surgery was 18.4 days. There was neither mortality nor severe complications. The surgical outcomes were class 1 for 28, class 2 for 13, class 3 for 19 and class 4 for 5. There were statistically significant differences between the symptom duration and the classes, and between the operation time and the classes. CONCLUSION: VATS pleural adhesiolysis and decortication are effective, safe treatments for managing complicated pleural SOL, and an earlier operation is needed for obtaining a better surgical outcome.

OBJECTIVETo evaluate the value of flexible fiberoptic bronchoscopy in diagnosis and treatment of pulmonary atelectasis in children.

METHODTotally 104 patients with pulmonary atelectasis, who were admitted to this department, received flexible fiberoptic bronchoscopy from January 2006 to May 2010, were enrolled in a retrospective analysis.

RESULTThe analysis on causes of pulmonary atelectasis showed that 76 cases (73%) of the 104 patients had sputum obstructions, which was the main cause of atelectasis. Thirteen cases (13%) had bronchopulmonary dysplasia, 9 cases among these were infants. Twelve cases (12%) had foreign body aspiration, 8 cases among these were under the age of 3-year. After flexible fiberoptic bronchoscopy, 100 cases got expansion of pulmonary atelectasis. Sixty-five of the sputum obstruction cases got atelectasis reexpansion after one time of flexible fiberoptic bronchoscopy. Eight of the sputum obstruction cases got atelectasis reexpansion after two times of flexible fiberoptic bronchoscopy. Two of the sputum obstruction cases got atelectasis reexpansion after three times of flexible fiberoptic bronchoscopy. The rate of atelectasis reexpansion after one time of alveolus lavement was higher in the cases whose courses of disease were under 3 weeks, than in the cases whose courses of disease were beyond 3 weeks.

CONCLUSIONEtiology of pulmonary atelectasis varied at different age. The morbidity of bronchopulmonary dysplasia was high in infants. Foreign body aspiration was the common cause of pulmonary atelectasis in children from 1 to 3-year of age. Sputum obstruction was the main cause of pulmonary atelectasis in over 3-year-old children. Most cases got atelectasis reexpansion after alveolar lavage. The patients who had shorter course of disease might have higher rate of atelectasis reexpansion after alveolar lavage once. Flexible fiberoptic bronchoscopy plays an important role in diagnosis and treatment of pulmonary atelectasis.

BACKGROUND: Separation of two lungs during anesthesia is necessary for the purpose of isolation of one lung from the other to prevent spillage or contamination and facilitating surgical exposure by collapsing the lung in the operative hemithorax. Several techniques are available for providing one-lung anesthesia. This study was performed to evaluate which technique is favored and why it is favored for one-lung ventilation. METHODS: We studied 70 patients scheduled for thoracic surgery aided by collapse of the ipsilateral lung. We analyzed frequency of each technique, efficacy of lung collapse, adequacy of one-lung ventilation, blood gases and complications. RESULTS: In the 63 patients out of 70 patients, the double-lumen tubes were used. Left-sided were used in 57 patients and right-sided were used in 6 patients. There were 3 complications: tracheal rupture, right bronchial rupture and post-operative edema of vocal cords. Bronchial blockers were inserted in 7 patients. It was failed in two cases. Ventilation and oxygenation were respectively good in all patients. CONCLUSIONS: We favored the double-lumen endotrachial tube than Univent blocker. Malposition was frequently seen with the Univent and serious complication was occasionally seen with the double-lumen tube. However surgical exposure and oxygenation was provided with any method, when position was corrected adequately.

BACKGROUND AND OBJECTIVEAtelectasis is a common complication after thoracotomy, and it may threaten patients' life if it was not treated correctly and properly. The aim of this article is to explore and discuss the prevention and treatment for atelectasis during the perioperative period, and also to explore new methods for reducing the perioperative mortality due to atelectasis after thoracotomy.

METHODSWe retrospectively reviewed the medical records of 374 lung cancer patients who underwent thoracotomy in our department between Jan 2007 and Nov 2009.

RESULTSAtelectasis occurred in 14 patients among all the 374 lung cancer patients who underwent thoracotomy. All the atelectasis returned to reexpansion after treatment.

CONCLUSIONThe incidence of atelectasis in these series is relatively low compared with the reports in literatures. Good perioperative preparation and perioperative treatment can remarkably decrease the incidence and mortality of atelectasis after thoracotomy in the treatment of lung cancer.

OBJECTIVETo review the clinical features and therapeutic experience in children with plastic bronchitis.

METHODSFourteen children with plastic bronchitis were reviewed retrospectively, 12 of which were under two years old. The clinical features are characterized by sudden onset, episodes of profound hypoxia and respiratory tract obstruction. SaO2 was between 0.70 and 0.80 even with mask oxygen inhalation. Eight cases were pyretic, 4 cases expectorated jel-like bronchial casts. The chest X-ray picture showed patchy consolidation or atelectasis unilaterally (10 cases) or bilaterally (2 cases). Pulmonary marking thickening and patchy shadow were observed in 2 cases. Twelve cases underwent rigid bronchoscopy and the bronchial casts were removed. Two cases underwent endotracheal intubation.

RESULTSEight cases of 12 children received therapeutic bronchoscopy were cured. Other 4 cases had second therapeutic bronchoscopy and bronchial casts were removed again in 3 cases, one died from pulmonary hemorrhage. Two cases who underwent endotracheal intubation died from the multiple organ failure (MOF). Pathologic results showed:the bronchial casts were composed mainly of mucus and fibrin, inflammatory cell infiltrate were observed in 6 cases (Type 1, inflammatory), no cellular infiltrate occurred in 8 cases (Type 2, acellular).

CONCLUSIONSPlastic bronchitis is a severe and dangerous disease. The branching plastic casts may obstruct part or the entire tracheobronchial, causing respiratory failure. Bronchoscopy and pathologic examination are essential for it's diagnosis and treatment.
