Hepatitis B virus （HBV） infection can cause acute or chronic infection， while untreated patients can develop into liver cirrhosis or liver cancer， thereby leading to death. As one of the most important organelles of cells， the maintenance of the normal morphology and function of mitochondria is the basis for ensuring various physiological activities in cells， and physiological activities， such as mitochondrial dynamics， mitophagy， injury， and oxidative phosphorylation， can affect the maintenance of mitochondrial homeostasis. HBV infection can affect mitochondrial homeostasis. This article summarizes the research advances in mitochondrial homeostasis and HBV infection from the four aspects of mitochondrial dynamics， mitophagy， mitochondrial oxidative phosphorylation， and mitochondrial injury and discusses the association between the maintenance of mitochondrial homeostasis and HBV infection， in order to provide a theoretical basis for understanding the molecular mechanism of HBV infection and identifying the potential therapeutic targets for HBV.

Objective:To evaluate the clinical diagnosis and laparoscopic surgical management of diaphragmatic rupture.Methods:Clinical data of 19 patients diagnosed with diaphragmatic hernia secondary to diaphragmatic rupture, admitted to the Sixth Affiliated Hospital of Sun Yat-sen University from Jan 2022 to Sep 2024 was retrospectively analyzed.Results:There were 7 males and 12 females. Traumatic etiology was confirmed in 9 cases, all developed after closed injuries, including one vehicular accident, seven blunt traumas, and one fall from height. Iatrogenic factors accounted for the remaining 10 cases. Left-sided diaphragmatic hernias were observed in 13 patients, while right-sided hernias occurred in 6 patients. Hiatal hernias were complicated in 5 patients. All patients underwent elective laparoscopic tension-free repair using composite patch for defect closure. Postoperatively, one patient was readmitted into ICU due to reexpansion pulmonary edema but was subsequently discharged following recovery. The median postoperative hospital stay was 10 days.Conclusions:The incidence of diaphragmatic rupture is relatively uncommon, primarily occurring as a result of traumatic or iatrogenic injuries. Early diagnosis coupled with prompt laparoscopic surgical intervention has proven to be effective in managing this condition.

Background and Aims:Laparoscopic hiatal hernia repair with mesh reinforcement combined with fundoplication has become the standard surgical approach for treating moderate to severe cases.However,intraoperative and postoperative complications remain a significant concern.This study was conducted to explore the causes of common complications and their prevention and management strategies through retrospectively analyzing clinical data from a single center to optimize perioperative care and improve surgical safety.Methods:The clinical data of 432 patients who underwent laparoscopic hiatal hernia repair with mesh and fundoplication at the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to December 2023 were retrospectively analyzed.All procedures were performed by the same surgical team using the standardized seven-step protocol for laparoscopic repair.Postoperative care followed the enhanced recovery after surgery pathway.The incidences of intraoperative and postoperative complications were recorded,and univariate analysis was used to identify risk factors for major postoperative complications.Results:The overall complication rate was 15.3％among 432 patients.The most common intraoperative complication was bleeding(6.9％),primarily from the inferior phrenic vessels(3.2％),short gastric vessels(1.6％),and parenchymal organ injuries(1.9％).The most frequent postoperative complication was dysphagia(12.0％),followed by pneumothorax(3.2％),hernia recurrence(1.9％),mesh infection or erosion(0.7％),gas-bloat syndrome(6.3％),and gastroparesis(0.9％).Most complications were relieved through conservative treatment,endoscopic dilation,or interventional procedures.Two patients with persistent dysphagia underwent reoperation to remove the fundoplication wrap.The median follow-up period was 34 months,with a 6.0％loss to follow-up rate and no perioperative mortality.Univariate analysis showed that patients aged ≥50 years and those who underwent Nissen fundoplication had significantly higher rates of postoperative dysphagia(both P＜0.05).Conclusion:Laparoscopic hiatal hernia repair with mesh and fundoplication is generally safe and effective.However,intraoperative vascular injuries and postoperative dysphagia require special attention.Accurate dissection and identification of anatomical layers are critical during surgery.Surgical strategy should be tailored based on patient age and esophageal motility,with partial fundoplication(Toupet or Dor)preferred when appropriate.Combined with enhanced postoperative recovery protocols,standardized mesh placement and fixation can reduce complication rates and improve long-term outcomes.

With the rising incidence of hiatal hernia and gastroesophageal reflux disease,surgical techniques urgently require refinement to improve patient outcomes.Guided by the concept of"anatomical priority",Professor Chen Shuang's team has established a standardized seven-step laparoscopic protocol,emphasizing three key components:precise dissection of the"sacred plane",three-dimensional crural reconstruction,and tension-controlled fundoplication.To address limitations such as restricted intraoperative visualization and poor reproducibility,the team further developed the innovative"necktie traction technique".This method employs a red pediatric catheter to create a dynamic traction system,enabling directional field exposure,axial esophageal repositioning,and quantitative control of fundoplication.Integrating biomechanical principles,the technique provides a visualized and standardized operative pathway,significantly enhancing surgical safety,efficacy,and reproducibility.As a novel approach combining anatomical restoration with functional anti-reflux reconstruction,the"necktie technique"offers robust technical support for the standardized promotion of laparoscopic anti-reflux surgery.

The surgical management of gastroesophageal reflux disease (GERD) has completed a paradigm shift from symptomatic palliation to curative intervention. For high-risk patients with pathological acid exposure (AET>6%), progressive anatomical destruction (e.g., ≥2 cm hiatal hernia or Hill grade III/IV lesions), or those requiring interruption of carcinogenic progression (such as Barrett's esophagus with dysplasia), anti-reflux surgery provides superior long-term efficacy compared to pharmacotherapy. Surgical indications require a three-dimensional assessment integrating anatomical, functional, and risk factors: patients with dominant anatomical defects are recommended to undergo combined hernia repair and fundoplication (biological mesh reinforcement for recurrent hernias reduces recurrence rates to 16.7%); functionally decompensated groups require decision-making based on objective reflux metrics (e. g.,>75 reflux events/24 hours); special populations such as post-bariatric GERD should preferentially undergo Roux-en-Y gastric bypass (reflux control rate: 93%), while those with motility disorders (e. g., scleroderma) are suitable for partial fundoplication to mitigate dysphagia risk (OR=0.285). Precision decision-making is achieved through a stepwise evaluation pathway (endoscopy→pH-impedance monitoring→high-resolution manometry). Intraoperative strategies are individualized based on motility status: patients with normal esophageal motility undergo the Nissen procedure, the elderly or those with ineffective esophageal motility are prioritized for Toupet fundoplication for optimized long-term safety, and magnetic sphincter augmentationenables 96% of PPI-responsive but medication-averse patients to discontinue drug dependency. The core value of surgical intervention lies in simultaneously achieving anatomical restoration and functional reconstruction, along with blocking Barrett's esophageal carcinogenesis (OR=0.41). This dual mechanism signifies a fundamental transformation in GERD management strategy.

Objective:To explore the efficacy and safety of laparoscopic Dor fundoplication in treating gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG).Methods:A retrospective analysis was conducted on 11 patients undergoing laparoscopic Dor fundoplication between Oct 2021 and Oct 2023. These patients had previously undergone LSG due to obesity and related metabolic diseases and developed GERD postoperatively. The GerdQ scale scores, results of endoscopy, upper gastrointestinal radiography, and gastric window color Doppler ultrasonography were analyzed.Result:Surgeries were successfully performed in these 11 patients. After esophageal hiatus repair, 10 patients underwent reinforcement of the diaphragmatic crus using biological or synthetic anti-adhesion patches. The average operative time was (120±31) minutes, and the average postoperative hospital stay was (9±3) days. Follow-up at 6 months revealed complete resolution of GERD symptoms in 10 patients. Intraoperatively one patient sustained injuries to the left hepatic vein and esophagus. Postoperative complications included one case of intestinal obstruction and one case of dysphagia, one patient failed to get experience improvement in GERD symptoms. All complications were managed successfully except for one needing re-admission for interventional esophageal balloon dilation due to dysphagia.Conclusion:Laparoscopic Dor fundoplication serves as a safe and effective revision surgery for GERD following LSG.
