BACKGROUND: Postoperative pulmonary complications often lead to increased mortality and financial burden. Residual paralysis plays a critical role in postoperative pulmonary complications. This meta-analysis was performed to determine whether sugammadex overmatches neostigmine in reducing postoperative pulmonary complications. METHODS: PubMed, Embase, Web of Science, Medline through Ovid, Cochrane Library, Wanfang, China National Knowledge Infrastructure, and Chinese BioMedical Literature Databases were searched from their inception to 24 June, 2021. Random effects models were used for all analyses. Cochrane risk of bias tool was used to assess the quality of RCTs, while Newcastle Ottawa Quality Assessment Scale was used to assess for the quality of cohort studies. RESULTS: Seventeen studies were included in the meta-analysis. Pooled data from cohort studies showed reversing neuromuscular blocking with sugammadex had less risk of compound postoperative pulmonary complications (relative risk [RR]: 0.73; 95% confidence interval [CI]: 0.60-0.89; P  = 0.002; I2  = 81%), pneumonia (RR: 0.64; 95% CI: 0.48-0.86; I2  = 42%) and respiratory failure (RR: 0.48; 95% CI: 0.41-0.56; I2  = 0%). However, pooled data from RCTs did not show any difference between the two groups in pneumonia (RR: 0.58; 95% CI: 0.24-1.40; I2  = 0%) and no respiratory failure was reported in the included RCTs. The difference was not found between sugammadex and neostigmine about atelectasis in pooled data from either RCTs (RR: 0.85; 95% CI: 0.69-1.05; I2  = 0%) or cohort studies (RR: 1.01; 95% CI: 0.87-1.18; I2  = 0%). CONCLUSION: The evidence of superiority of sugammadex was limited by the confounding factors in cohort studies and small scale of RCTs. Whether sugammadex precedes neostigmine in preventing pulmonary complications after surgery is still unknown. Well-designed RCTs with large scale are needed.

The risk of developing perioperative acute kidney injury (AKI) in elderly patients increases with age. The combined involvement of aging kidneys, coexisting multiple underlying chronic diseases, and increased exposure to potential renal stressors and nephrotoxic drugs or invasive procedures constitute susceptibility factors for AKI in elderly patients. The perioperative AKI in elderly patients undergoing noncardiac surgery has its own specific population characteristics, so it is necessary to further explore the characteristics of AKI in elderly patients in terms of epidemiology, clinical diagnosis, risk factors, and preventive and curative measures to provide meaningful clinical advice to improve prognosis, accelerate recovery, and reduce medical burden in elderly patients. Since AKI has the fastest-growing incidence in older patients and is associated with a worse prognosis, early detection, early diagnosis, and prevention of AKI are important for elderly patients in the perioperative period. Large, multicenter, randomized controlled clinical studies in elderly non-cardiac surgery patients with AKI can be conducted in the future, with the aim of providing the evidence to reduce of the incidence of AKI and to improve the prognosis of patients.

Surgery is the primary treatment for esophageal cancer, but the postoperative complication rate remains high. Therefore, it is important to prevent and manage postoperative complications to improve prognosis. Common perioperative complications of esophageal cancer include anastomotic leakage, gastrointestinal tracheal fistula, chylothorax, and recurrent laryngeal nerve injury. Respiratory and circulatory system complications, such as pulmonary infection, are also quite common. These surgery-related complications are independent risk factors for cardiopulmonary complications. Complications, such as long-term anastomotic stenosis, gastroesophageal reflux, and malnutrition are also common after esophageal cancer surgery. By effectively reducing postoperative complications, the morbidity and mortality of patients can be reduced, and their quality of life can be improved.

Objective: To explore the value of electrically evoked auditory brainstem response (EABR) monitoring combined with brainstem auditory evoked potential (BAEP) and compound action potential (CAP) monitoring during vestibular schwannoma resection for the protection of the cochlear nerve. Methods: Clinical data from 12 patients with vestibular schwannomas who had useful hearing prior to surgery were analyzed at the PLA General Hospital from January to December 2021. Among them, there were 7 males and 5 females, ranging in age from 25 to 59 years. Before surgery, patients underwent audiology assessments (including pure tone audiometry, speech recognition rate, etc.), facial nerve function evaluation, and cranial MRI. They then underwent vestibular schwannoma resection via the retrosigmoid approach. EABR, BAEP, and CAP were simultaneously monitored during surgery, and patients' hearing preservation was observed and analyzed after surgery. Results: Prior to surgery, the average PTA threshold of the 12 patients ranged from11 to 49 dBHL, with a SDS of 80% to 100%. Six patients had grade A hearing, and six patients had grade B hearing. All 12 patients had House-Brackman grade I facial nerve function prior to surgery. The MRI indicated tumor diameters between 1.1 and 2.4 cm. Complete removal was achieved in 10/12 patients, while near-total removal was achieved in 2/12 patients. There were no serious complications at the one-month follow-up after surgery. At the three-month follow-up, all 12 patients had House-Brackman grade I or II facial nerve function. Under EABR with CAP and BAEP monitoring, successful preservation of the cochlear nerve was achieved in six of ten patients (2 with grade B hearing, 3 with grade C hearing, and 1 with grade D hearing). Successful preservation of the cochlear nerve was not achieved in another four patients (all with grade D hearing). In two patients, EABR monitoring was unsuccessful due to interference signals; however, Grade C or higher hearing was successfully preserved under BAEP and CAP monitoring. Conclusion: The application of EABR monitoring combined with BAEP and CAP monitoring during vestibular schwannoma resection can help improve postoperative preservation of the cochlear nerve and hearing.

Objective: To investigate the value of reconstruction of pelvic floor with biological products to prevent and treat empty pelvic syndrome after pelvic exenteration (PE) for locally advanced or recurrent rectal cancer. Methods: This was a descriptive study of data of 56 patients with locally advanced or locally recurrent rectal cancer without or with limited extra-pelvic metastases who had undergone PE and pelvic floor reconstruction using basement membrane biologic products to separate the abdominal and pelvic cavities in the Department of Anorectal Surgery of the Second Affiliated Hospital of Naval Military Medical University from November 2021 to May 2022. The extent of surgery was divided into two categories: mainly inside the pelvis (41 patients) and including pelvic wall resection (15 patients). In all procedures, basement membrane biologic products were used to reconstruct the pelvic floor and separate the abdominal and pelvic cavities. The procedures included a transperitoneal approach, in which biologic products were used to cover the retroperitoneal defect and the pelvic entrance from the Treitz ligament to the sacral promontory and sutured to the lateral peritoneum, the peritoneal margin of the retained organs in the anterior pelvis, or the pubic arch and pubic symphysis; and a sacrococcygeal approach in which biologic products were used to reconstruct the defect in the pelvic muscle-sacral plane. Variables assessed included patients' baseline information (including sex, age, history of preoperative radiotherapy, recurrence or primary, and extra-pelvic metastases), surgery-related variables (including extent of organ resection, operative time, intraoperative bleeding, and tissue restoration), post-operative recovery (time to recovery of bowel function and time to recovery from empty pelvic syndrome), complications, and findings on follow-up. Postoperative complications were graded using the Clavien-Dindo classification. Results: The median age of the 41 patients whose surgery was mainly inside the pelvis was 57 (31-82) years. The patients comprised 25 men and 16 women. Of these 41 patients, 23 had locally advanced disease and 18 had locally recurrent disease; 32 had a history of chemotherapy/immunotherapy/targeted therapy and 24 of radiation therapy. Among these patients, the median operative time, median intraoperative bleeding, median time to recovery of bowel function, and median time to resolution of empty pelvic syndrome were 440 (240-1020) minutes, 650 (200-4000) ml, 3 (1-9) days, and 14 (5-105) days, respectively. As for postoperative complications, 37 patients had Clavien-Dindo < grade III and four had ≥ grade III complications. One patient died of multiple organ failure 7 days after surgery, two underwent second surgeries because of massive bleeding from their pelvic floor wounds, and one was successfully resuscitated from respiratory failure. In contrast, the median age of the 15 patients whose procedure included combined pelvic and pelvic wall resection was 61 (43-76) years, they comprised eight men and seven women, four had locally advanced disease and 11 had locally recurrent disease. All had a history of chemotherapy/ immunotherapy and 13 had a history of radiation therapy. The median operative time, median intraoperative bleeding, median time to recovery of bowel function, and median time to relief of empty pelvic syndrome were 600 (360-960) minutes, 1600 (400-4000) ml, 3 (2-7) days, and 68 (7-120) days, respectively, in this subgroup of patients. Twelve of these patients had Clavien-Dindo < grade III and three had ≥ grade III postoperative complications. Follow-up was until 31 October 2022 or death; the median follow-up time was 9 (5-12) months. One patient in this group died 3 months after surgery because of rapid tumor progression. The remaining 54 patients have survived to date and no local recurrences have been detected at the surgical site. Conclusion: The use of basement membrane biologic products for pelvic floor reconstruction and separation of the abdominal and pelvic cavities during PE for locally advanced or recurrent rectal cancer is safe, effective, and feasible. It improves the perioperative safety of PE and warrants more implementation.

Defunctioning stoma is an effective method to reduce symptomatic anastomotic leakage after rectal cancer surgery. It is of concern that about 1 in 5 defunctioning stomas will not be restored, that is, becoming permanent. And that is usually beyond expectation by physicians and patients, which deserves enough attention. The causes are complex, including anastomotic complications, tumor progression, perioperative death, poor anal function and patient willingness. Possible risk factors include symptomatic anastomotic leakage, age, tumor location, neoadjuvant therapy, anal function, TNM stage, ASA score, hospital factors, etc. Those factors may occur in various stages of patient referral such as before neoadjuvant therapy, prior to surgery, intra or post-operative period, and follow-up. Adequate physician-patient communication and shared decision-making, comprehensive tumor and patient function assessment, rational treatment strategy, careful manipulation during operation and good quality control, and meticulous perioperative management are important steps to reduce the permanent stoma. When shared decision-making, patients' needs should be fully considered while unnecessary expectations of anal preservation should be avoided. The risk of perpetuation of defunctioning stoma should be fully informed. Safe operation, especially anastomosis, is the key to avoid permanent stoma. And attention should be paid to the early detection and intervention of postoperative anastomotic stenosis.

OBJECTIVE: To explore the effectiveness and feasibility of dexamethasone combined with oxybuprocaine hydrochloride gel on the prevention of postoperative sore throat after nasal endoscopy. METHODS: In the study, 60 patients with American Society of Anesthesiologist (ASA) physical statuses Ⅰ to Ⅱ, aged 18 to 72 years, scheduled for elective nasal endoscope surgery under general anesthesia requiring endotracheal intubation were randomly divided into dexamethasone combined with oxybuprocaine hydrochloride gel group (G group, n=30) and control group (C group, n=30). The patients in the G group received dexamethasone 0.1 mg/kg before induction and the oxybuprocaine gel was applied to the endotracheal catheter cuff and the front end within 15 cm. The patients in the C group received the same dose of saline and the saline was applied to the endotracheal catheter cuff and the front end within 15 cm. Then, all the patients in the two groups received the same induction and anesthesia maintainance. The operation time, anesthesia time, emergence time, extubation time and departure time were recorded. The intraoperative infusion volume, blood loss volume, propofol, remifentanil, rocuronium dosage were also recorded. The adverse reactions such as intraoperative hypotension, bradycardia and postoperative agitation were recorded. The postoperative sore throat score was recorded at the end of operation and 4 h, 8 h, 12 h, and 24 h after operation. RESULTS: Compared with the C group, the emergence time [(8.4±3.9) min vs. (10.8±4.7) min], extubation time [(8.8±3.7) min vs. (11.9±4.8) min], and departure time [(20.0±5.3) min vs. (23.0±5.8) min] were significantly shorter, and the propofol dosage [(11.8±1.8) mg/kg vs. (15.9±4.6) mg/kg], remifentanil dosage [(10.9±4.7) μg/kg vs. (14.1±3.6) μg/kg] were significantly less in the G group, and there was no difference of rocuronium dosage in the two groups. Compared with the C group the incidence of intraoperative hypotension [10%(3/30) vs. 30%(9/30)], bradycardia [16.7%(5/30) vs. 20%(6/30)] and postoperative agitation [6.7%(2/30) vs. 23.3%(7/30)] were significantly lower in the C group. The postoperative sore throat score at the end of operation, 4 h, 8 h, 12 h and 24 h after operation in the G group were significantly lower than in the C group respectively [0 (0, 1) vs. 1 (1, 2), 0 (0, 0) vs. 1 (1, 2), 0 (0, 0) vs. 1 (1, 2), 0 (0, 0) vs. 1 (0.75, 1), 0 (0, 0) vs. 1 (0, 1)]. CONCLUSION Dexamethasone combined with oxybuprocaine hydrochloride gel was effective and feasible on the prevention of postoperative sore throat after nasal endoscopy.
