Objective To investigate the preventive measures for bleeding in laparoscopic hepatectomy. Methods The candidates for laparoscopic hepatectomy were 22 patients with live lesions， including 5 patients with primary liver cancer， 16 patients with liver hemangioma， and 1 patient with metastatic liver cancer. The tumors locatedthe left lateral lobe in 15 cases， caudate lobe in 1 case， segmentⅣin 2 cases， and segmentⅥ in 4 cases. The meandiameter of tumors was 4cm （2-10cm）. The surgical approaches included the left lateral lobectomy （15 cases）， leftlateral lobectomy of caudate （1 case）， and nonanatomic and wedge resection were performed in 6 cases. Results Twenty-two cases underwent laparoscopic liver resection， there were no conversion to open and operative death. The mean operative time was 115min （65-142min）， the mean blood loss was 450mL （270-780mL）， the mean length of hospital stay after operation was 6.5 days （3-11 days）. Conclusion Control liver section hemorrhage is a key technique in laparoscopic hepatectomy.
Transit time flow measurement (TTFM),which is independent of vessel size and shape, has been considered to be an easy, reproducible and non-invasive method to assess the hemodynamic characteristics. Moreover, current studies have shown that TTFM has clinical application in identifying the function of grafted vessel and prognosis. Researchers have proved some reliable indicators for the function of grafted vessel as follows: mean graft flow (MGF) > 15 ml/min, diastolic flow (DF) >50% and pulsatility index (PI)<3 or 5. This article focuses on the review of clinical application and research progress of TTFM in CABG.
Objective To explore whether the intraoperative cholangiography （IOC） should be applied in laparoscopic cholecystectomy routinely or selectively. Methods Data of routine IOC group （1 520 patients）and selective IOC group （457 patients）in laparoscopic cholecystectomy were collected and analyzed， including cholangiography time， success rate， common bile duct stones rate， open cholecystectomy rate， and hospital stay after operation. All IOC cases were performed by home-made cholangiography appliance or infusion needle. Results There were no significant differences between routine IOC group and selective IOC group on cholangiography time， success rate， open cholecystectomy rate， and hospital stay after operation （P＞0.05）. However， compared with routine IOC group， the common bile duct stones rate， anatomic variation rate， and iatrogenic damage rate were significantly higher in selective IOC group （28.25% vs. 13.43%， 10.71% vs. 7.43%， 2.05% vs. 1.02%， P＜0.05）. Conclusions For avoiding iatrogenic bile duct damage and residual stones， routine IOC should be applied in early-stage of laparoscopic cholecystectomy， and IOC should be applied selectively when the surgeon have LC technique at their finger ends.
Objective To evaluate the effect of intraoperative fluid infusion volume on postoperative pulmonary complications (PPCs) in patients after minimally invasive endoscopic esophageal carcinoma resection. Methods From June 2019 to August 2021, 486 patients undergoing elective minimally invasive endoscopic esophagectomy for esophageal cancer were retrospectively screened from the electronic medical record information management system and anesthesia surgery clinical information system of West China Hospital of Sichuan University. There were 381 males and 105 females, with a median age of 64.0 years. Taking the incidence of pulmonary complications within 7 days after operation as the primary outcome, the correlation between intraoperative fluid infusion volume and the occurrence of PPCs within 7 days was clearly analyzed by regression analysis. ResultsThe incidence of pulmonary complications within 7 days after surgery was 33.5% (163/486). Regression analysis showed that intraoperative fluid infusion volume was correlated with the occurrence of PPCs [adjusted OR=1.089, 95%CI (1.012, 1.172), P=0.023], especially pulmonary infection [adjusted OR=1.093, 95%CI (1.014, 1.178), P=0.020], and pleural effusion [adjusted OR=1.147, 95%CI (1.007, 1.306), P=0.039]. Pulmonary infection was significantly less in the low intraoperative fluid infusion group [<6.49 mL/(kg·h), n=115] compared with the high intraoperative fluid infusion group [≥6.49 mL/(kg·h), n=371] (18.3% vs. 34.5%, P=0.023). Intraoperative fluid infusion volume was positively associated with death within 30 days after surgery [adjusted OR=1.442, 95%CI (1.056, 1.968), P=0.021]. Conclusion Among patients undergoing elective minimally invasive endoscopic esophageal cancer resection, intraoperative fluid infusion volume is related with the occurrence of PPCs within 7 days after the surgery, especially pulmonary infection and pleural effusion, and may affect death within 30 days after the surgery.
Objective To summarize application effect and clinical experience of multimodal intraoperative neurophysiological monitoring (IONM) technology in the surgery of neurofibromatosis type 1 (NF1) related peripheral nerve tumors. Methods A retrospective study was conducted on NF1 patients, who admitted between January 2019 and December 2023 and treated with peripheral nerve tumor resection surgery assisted by multimodal IONM technology. There were 49 males and 45 females. The age ranged from 5 to 78 years, with an average of 33.7 years. Tumor morphological classification included 71 cases of nodular type, 13 cases of diffuse type, and 10 cases of mixed type. Target tumors were distributed in craniofacial region (47 cases), neck (11 cases), trunk (12 cases), and limbs (24 cases). Preoperatively, 44 cases had no obvious neurological symptoms, while the remaining patients had neurological symptoms, including 15 cases of visual impairment, 5 cases of hearing impairment, 16 cases of somatic movement disorders, and 31 cases of somatic sensory disorders, of which 7 cases had more than one symptom. IONM plans were selected based on the relevant nerves and adjacent important structures of the target tumor, including visual evoked potential (17 cases), somatosensory evoked potential (44 cases), motor evoked potential (88 cases), and electromyogram (94 cases).Results All surgeries were successfully completed. Ninety-three patients underwent total/near total resection and 1 patient underwent palliative resection. Pathological examination showed 80 cases of neurofibroma and 14 cases of malignant peripheral nerve sheath tumors. Complications included 2 cases of hematoma and 3 cases of incision infection. All patients were followed up 3-61 months (median, 15 months). During follow-up, no significant changes in neurological symptoms or tumor recurrence were found. Among the patients with preoperative visual impairment, there were 14 cases with no improvement in symptoms and 1 with improvement after surgery. Among the patients with somatic movement disorders, there were 11 cases with no improvement in symptoms, 3 cases with improvement, 2 cases with aggravation, 4 newly onset cases, and 1 case with significant impact on daily life after surgery. Among the patients with somatic sensory disorders, there were 17 cases with no improvement in symptoms, 14 cases with improvement, and 13 newly onset cases. The patients with hearing impairment showed improvement after surgery. Conclusion The clinical manifestations of NF1 related peripheral nerve tumors are complex. Multimodal IONM technology can provide real-time detection of nerve provocation and damage. Surgical treatment with multimodal IONM technology is safe and can reduce complications.
