Acute pancreatitis is a common surgical emergency characterized by severe local or systemic complications during its progression. Diseases of the biliary system are among the serious local complications of acute pancreatitis, primarily including acute acalculous cholecystitis (AAC) and biliary stricture. AAC often occurs in the later stages of acute pancreatitis, exacerbating systemic inflammation and leading to organ failure and life-threatening conditions in severe cases. Biliary stricture is a rare but serious long-term complication of acute pancreatitis, which can induce cholangitis, progressive liver function impairment, and secondary biliary cirrhosis. Due to the clinical symptoms of acute pancreatitis that can mask biliary system diseases, some patients may not receive timely diagnosis and treatment for concurrent biliary issues during the onset of acute pancreatitis, which can be life-threatening in severe cases. Currently, the ideal treatment strategy for biliary system complications secondary to acute pancreatitis remains unclear, lacking definitive guidelines or consensus. This article integrates recent research developments from both domestic and international studies to elucidate the pathogenesis, diagnosis, and treatment strategies for biliary system complications secondary to acute pancreatitis.

Objective To investigate the risk factors of short-term adverse prognosis and the predictive value of Charlson comorbidities index(CCI)in patients with central pulmonary embolism(PE).Methods 115 cases of central PE patients were retrospectively analyzed.According to the adverse prognosis during hospitalization,the subjects were divided into adverse event group and no adverse event group.The clinical characteristics of the ad-verse event group were analyzed.Multivariate Logistic regression analysis was performed for statistically significant indicators.Results The most common clinical symptoms of central PE patients were chest distress or dyspnea(77.4％ ),followed by cough(35.7％ ),chest pain(28.7％ ),syncope(9.6％ )and hemoptysis(7.8％ ).There were no statistically significant differences in gender,smoking history,drinking history,symptoms and signs between the two groups.In univariate analysis,CCI,grouping score of thrombus location,white blood cell count,neutrophil count and urea nitrogen were associated with adverse events in central PE patients,with statistical signif-icance(P＜0.05).After Logistic regression multivariate analysis,increased neutrophil count(OR=1.494,95％ CI:1.073-2.080,P=0.017)was an independent risk factor(P＜0.05).The CCI in the group with adverse e-vents was higher than that in the group without adverse events(P=0.004).Multivariate analysis showed that in-creased CCI(Oβ=1.342,95％ CI:1.022-1.763,P=0.034)was an independent risk factor,and the risk of adverse events increased by 34.2％ for every one-point increase in CCI.The thrombus location score of the group with adverse events was significantly higher than that of the group without adverse events(OR=2.586,95％ CI:1.366-4.896,P=0.004),and the risk of adverse events increased 1.586 times with each increase of thrombus location score.Conclusion Increased neutrophil count,CCI,and thrombus location score are associated with poor short-term prognosis in central PE patients.

The clinical data from 16 patients who underwent surgery for acute type A aortic dissection under ultra-fast-track anesthesia (UFTA) in the Second Affiliated Hospital of Nanjing Medical University from August 2023 to December 2023 were collected, and the experience of anesthesia management was analyzed and summarized. UFTA strategy was to reduce inflammation and perform multi-organ protection in the perioperative period through cardiopulmonary bypass methods, medications, etc. According to the process of operation, the long-term and short-acting anesthetic drugs were accurately used to achieve the patient′s awakening immediately after the operation. Deep anesthesia extubation, remifentanil infusion techniques, and nasal high-flow ventilation were used to enable patients to be removed from the endotracheal tube with low stress under the premise of safety. All the patients successfully completed anesthesia induction and anesthesia maintenance. The average surgery duration was (413±92) min, the average anesthesia duration was (480±100) min, the cardiopulmonary bypass time was (168±42) min, the cardiac arrest time was (119±36) min, and the deep hypothermic circulatory arrest lasted (24±5) min. Of these patients, 14 underwent deep hypothermic circulatory arrest combined with unilateral cerebral perfusion via the right axillary artery, and 2 underwent deep hypothermic circulatory arrest combined with retrograde cerebral perfusion via the superior vena cava. All the patients had their tracheal tubes removed within 30 min postoperatively, with blood gas analysis and hemodynamics being within or close to normal ranges. The average postoperative intensive care unit stay time was 6 (3, 11) days, and the total length of hospital stay was (23±8) days. The total hospitalization time extended 20 days in 7 patients due to postoperative complications. All the patients recovered and were discharged. In conclusion, the application of UFTA strategy is safe and feasible in the patients with acute type A aortic dissection, allowing for immediate extubation in the operating room.

BACKGROUND: Management of gastric leak after sleeve gastrectomy (SG) is challenging due to its unpredictable outcomes. We aimed to summarize the characteristics of SG leaks and analyze interventions and corresponding outcomes in a real-world setting. METHODS: To retrospectively review of 15,721 SG procedures from 2010 to 2020 based on a national registry. A cumulative sum analysis was used to identify a fitting curve of gastric leak rate. The Kaplan-Meier method and log-rank tests were performed to calculate and compare the probabilities of relevant outcomes. The logistic regression analysis was conducted to determine the predictors of acute leaks. RESULTS: A total of 78 cases of SG leaks were collected with an incidence of 0.5% (78/15,721) from this registry (6 patients who had the primary SG in non-participating centers). After accumulating 260 cases in a bariatric surgery center, the leak rate decreased to a stably low value of under 1.17%. The significant differences presented in sex, waist circumference, and the proportion of hypoproteinemia and type 2 diabetes at baseline between patients with SG leak and the whole registry population ( P = 0.005, = 0.026, <0.001, and = 0.001, respectively). Moreover, 83.1% (59/71) of the leakage was near the esophagogastric junction region. Leakage healed in 64 (88.9%, 64/72) patients. The median healing time of acute and non-acute leaks was 5.93 months and 8.12 months, respectively. Acute leak (38/72, 52.8%) was the predominant type with a cumulative reoperation rate >50%, whereas the cumulative healing probability in the patients who required surgical treatment was significantly lower than those requring non-surgical treatment ( P = 0.013). Precise dissection in the His angle area was independently associated with a lower acute leak rate, whereas preservation ≥2 cm distance from the His angle area was an independent risk factor. CONCLUSIONS Male sex, elevated waist circumference, hypoproteinaemia, and type 2 diabetes are risk factors of gastric leaks after SG. Optimizing surgical techniques, including precise dissection of His angle area and preservation of smaller gastric fundus, should be suggested to prevent acute leaks.

Objective:To explore the current situation of hypoglycemia fear of elderly patients with type 2 diabetes mellitus (T2DM) in the community, identify different types of hypoglycemia fear among elderly T2DM patients in the community by latent profile analysis, and analyze its influencing factors, so as to provide reference for formulating intervention measures.Methods:From February to April 2023, convenience sampling was used to select 300 elderly T2DM patients from three community health service centers in Shunqing District, Nanchong City, Sichuan Province as the research subject. The self-designed General Information Questionnaire, the Chinese Version Hypoglycemia Fear Survey-Ⅱ (CHFS-Ⅱ), and the Summary Diabetes Self Care Activities (SDSCA) were used to investigate the patients, and the latent profile of hypoglycemia fear was analyzed. Binary Logistic regression was used to analyze the influencing factors of different latent categories of hypoglycemic fear in elderly T2DM patients in the community.Results:A total of 300 questionnaires were distributed, and 290 valid questionnaires were collected, with an effective response rate of 96.7% (290/300). Among 290 elderly T2DM patients in the community, the hypoglycemia fear could be divided into two latent categories, including the "moderate worry-normal coping" group ( n=134) and the "high fear-cautious behavior" group ( n=156). The binary Logistic regression showed that marital status, whether there were complications of diabetes, treatment plan and self-management were the factors influencing the latent categories of elderly T2DM patients in the community, and the difference was statistically significant ( P<0.05) . Conclusions:There are classification characteristics of hypoglycemic fear levels in elderly T2DM patients in the community. Community medical and nursing staff should early identify patients in the "high fear-cautious behavior" group, regularly carry out targeted hypoglycemic health education and psychological intervention, reduce their hypoglycemic fear, and improve their quality of life.

Objective: To investigate the current situation and related factors of facial trauma in school age children in urban areas of Fuyang, and to provide basis for child facial trauma prevention. Methods: By cluster stratified random sampling method, a questionnaire survey was conducted among parents of school age children aged 3-6 in four kindergartens in Fuyang City. A total of 1 062 valid questionnaires were included. Results: A total of 146 (13.7%) children with facial trauma were included. The ratio of boys to girls was 1.84∶1.In primary and secondary classes in kindergarten, the reporting rate of boys (24.5%,16.4%) was higher than that of girls (13.4%, 9.0%), and the difference was statistically significant ( χ 2=6.66, 4.25, P <0.05).The incidence of facial trauma was highest (19.4%) in junior kindergarten class children, which decreased with age. Falls injury(61.6%) was the leading cause of facial trauma. Most of facial trauma occurred in family (55.5%) and kindergarten (26.0%). Forehead (26.0%) and mandible (21.2%) were the main injured body sites. Skin laceration (81.5%) was the main type of injury. Facial trauma mostly occurred at 11:00-13:00(19.9%) and 17:00-19:00(27.4%), during June to August (39.7%). The results of univariate analysis showed that the facial trauma of preschool children was associated with gender, class, parentrated child temperament, parental education and family type( χ 2=14.51,18.84,39.66,6.56,12.31, P <0.05). Conclusion Facial trauma in preschool children in Fuyang is common, which varies in gender, class, temperament and family type.

Objective: To investigate the safety and efficacy of surgical treatment for chronic radiation intestinal injury. Methods: A descriptive cohort study was performed. Clinical data of 73 patients with definite radiation history and diagnosed clinically as chronic radiation intestinal injury, undergoing operation at Department of Colorectal Surgery, the Sixth Affiliated Hospital of Sun Yat-sen University from January 1, 2012 to February 28, 2019, were reviewed and analyzed retrospectively. Patients did not undergo operation or only received adhesiolysis were excluded. All the patients had preoperative examination and overall evaluation of the disease. According to severity of intestinal obstruction and patients′ diet, corresponding nutritional support and conservative treatment were given. Surgical methods: The one-stage bowel resection and anastomosis was the first choice for surgical treatment of chronic radiation intestinal injury. Patients with poor nutritional condition were given enterostomy and postoperative enteral nutrition and second-stage stoma closure and intestinal anastomosis if nutritional condition improved. For those who were unable to perform stoma closure, a permanent stoma should be performed. Patients with severe abdominal adhesion which was difficult to separate, enterostomy or bypass surgery after adhesiolysis would be the surgical choice. For patients with tumor metastasis or recurrence, enterostomy or bypass surgery should be selected. Observation parameters: the overall and major (Clavien-Dindo grades III to V) postoperative complication within 30 days after surgery or during hospitalization; mortality within postoperative 30 days; postoperative hospital stay; time to postoperative recovery of enteral nutrition; time to removal of drainage tube. Results: Of the 73 patients who had been enrolled in this study, 10 were male and 63 were female with median age of 54 (range, 34-80) years. Preoperative evaluation showed that 61 patients had intestinal stenosis, 63 had intestinal obstruction, 11 had intestinal perforation, 20 had intestinal fistula, 3 had intestinal bleeding, and 6 had abdominal abscess, of whom 64(87.7%) patients had multiple complications. Tumor recurrence or metastasis was found in 15 patients. A total of 65(89.0%) patients received preoperative nutritional support, of whom 35 received total parenteral nutrition and 30 received partial parenteral nutrition. The median preoperative nutritional support duration was 8.5 (range, 6.0-16.2) days. The rate of one-stage intestine resection was 69.9% (51/73), and one-stage enterostomy was 23.3% (17/73). In the 51 patients undergoing bowel resection, the average length of resected bowel was (50.3±49.1) cm. Among the 45 patients with intestinal anastomosis, 4 underwent manual anastomosis and 41 underwent stapled anastomosis; 36 underwent side-to-side anastomosis, 5 underwent end-to-side anastomosis, and 4 underwent end-to-end anastomosis. Eighty postoperative complications occurred in 39 patients and the overall postoperative complication rate was 53.4% (39/73), including 39 moderate to severe complications (Clavien-Dindo grade III-V) in 20 patients (27.4%, 20/73) and postoperative anastomotic leakage in 2 patients (2.7%, 2/73). The mortality within postoperative 30 days was 2.7% (2/73); both patients died of abdominal infection, septic shock, and multiple organ failure caused by anastomotic leakage. The median postoperative hospital stay was 13 (11, 23) days, the postoperative enteral nutrition time was (7.2±6.9) days and the postoperative drainage tube removal time was (6.3±4.2) days. Conclusions Surgical treatment, especially one-stage anastomosis, is safe and feasible for chronic radiation intestine injury. Defining the extent of bowel resection, rational selection of the anatomic position of the anastomosis and perioperative nutritional support treatment are the key to reduce postoperative complications.

Objective: To explore clinical features and prognosis factors of surgical complications after intersphincteric resection (ISR) for low rectal cancer following neoadjuvant chemoradiotherapy. Methods: The clinical data of 132 patients with low rectal cancer who underwent ISR following neoadjuvant chemoradiotherapy from September 2010 to June 2017 at Department of Colorectal Surgery, Sixth Affiliated Hospital, Sun Yat-sen University were retrospectively reviewed. There were 100 males and 32 females, with the age of (52.9±11.4) years and distance to anal verge of 3.9 cm. Records of perioperative complication (POC) within 30 days after surgery, anastomotic leakage (AL), and anastomotic stenosis (AS) were analyzed. POC was recorded according to the Clavien-Dindo classification. AL was graded by ISREC system and classified into the early AL within 30 days after surgery and delayed AL beyond 30 days. AS was defined as narrowing of the bowel lumen at the anastomosis that prevented passage through a colonoscope with a 12 mm diameter. According to the shape of narrowing, AS was recorded as the stenosis in situ or stenosis with long-segment bowel above. Univariate and multivariate analysis were used to identify risk factors of anastomotic complications. Results: Among the 132 patients, full-dose radiotherapy and diverting stoma were performed in 128 (97.0%) patients, respectively. In entire cohort, AL was found in 41 (31.1%) patients, including 32 patients with clinical leakage (24.2%). The median time for diagnosis of AL was 37 days (2 to 214 days) after surgery. There were 25 patients (18.9%) who were diagnosed with delayed AL beyond 30 days. Chronic presacral sinus formation was detected in 22 of 129 (17.1%) patients at 12 months from surgery. Among the 128 eligible patients, 36 (28.1%) were diagnosed as AS, including 24 (18.8%) patients with stenosis in situ and 12 (9.4%) patients with bowel stenosis above. After a median follow-up of 26 months, 7(5.3%) patients received permanent colostomy and the other 20(15.2%) patients retained a persistent ileostomy, owing to anastomotic complications. Results of multivariate analysis showed that radiation colitis was an independent prognosis factor of AL after ISR (OR=5.04, 95% CI: 2.05 to 12.43, P=0.000); male gender (OR=5.19, 95% CI: 1.24 to 21.75, P=0.024) and AL (OR=8.49, 95% CI: 3.32 to 21.70, P=0.000) were independent prognosis factors of AS after ISR. Conclusions Surgical complications are common after ISR for low rectal cancer patients with neoadjuvant chemoradiotherapy. A high rate of AL is observed after long-term follow-up, which is associated with AS. Increasing awareness of anastomotic complications after ISR should be raised, especially for male patients with radiation colitis.
