Abstract
Three-dimensional visualization technology (3DVT) has been recently introduced to achieve a precise preoperative planning of liver surgery. The aim of this observational study was to assess the accuracy of 3DVT for complex liver resections. 3DVT with hyper accuracy three-dimensional (HA3D™) technology was introduced at our institution on February 2020. Anatomical characteristics were collected from two-dimensional imaging (2DI) and 3DVT, while intraoperative and postoperative outcomes were recorded prospectively. A total of 62 patients were enrolled into the study. 3DVT was able to study tumor extension and liver anatomy, identifying at least one vascular variation in 37 patients (59.7%). Future remnant liver volume (FRLV) was measured using 2DI and 3DVT. The paired samples t test assessed positive correlation between the two methods (p < 0.001). At least one vessel was suspected to be invaded by the tumor in 8 (15.7%) 2DI cases vs 16 (31.4%) 3DVT cases, respectively. During surgery, vascular invasion was detected in 17 patients (33.3%). A total of 73 surgical procedures were proposed basing on 2DI, including 2 alternatives for 16 patients. After 3DVT, the previously planned procedure was changed in 15 cases (29.4%), due to the clearer information provided. A total of 51 patients (82%) underwent surgery. The most frequent procedure was right hepatectomy (33.3%), followed by left hepatectomy (23.5%) and left trisectionectomy (13.7%). Vascular resection and reconstruction were performed in 10 patients (19.6%) and portal vein was resected in more than half of these cases (66.7%). 3DVT leads to a more detailed and tailored approach to complex liver surgery, improving surgeons' knowledge of liver anatomy and accuracy of liver resection.

Abstract
BACKGROUND The safety and feasibility of primary closure after laparoscopic common bile duct exploration (LCBDE) have been confirmed in elective settings. However, the suitability of primary closure after LCBDE in the treatment of patients with non-severe acute cholangitis in emergency settings remains unclear. The aim of the present study was to explore the safety and feasibility of LCBDE with primary closure in patients with non-severe acute cholangitis. METHODS Consecutive patients with choledocholithiasis combined with gallbladder stones treated by LCBDE with primary closure at our institution from January 2015 to April 2021 were retrospectively reviewed. These patients were divided into two groups: emergency group (patients with non-severe acute cholangitis) and elective group (patients without acute cholangitis). The demographic and perioperative data of the two groups were compared. RESULTS One hundred twenty-two patients received LCBDE combined with primary closure during this period, including 70 in the emergency group and 52 in the elective group. Baseline characteristics were balanced in both groups, except for higher levels of white blood cells (WBC), C-reactive protein (CRP), total bilirubin, alkaline phosphatase (ALP), and albumin in the emergency group. No postoperative mortality occurred in either group. Compared to the elective group, the emergency group had a longer operation time (P = 0.011), and more estimated blood loss (P < 0.001). No significant differences were found between the two groups in terms of conversion (2.9% vs. 0.0%, P = 0.507), use of baskets (84.2% vs. 78.8%, P = 0.481), use of electrohydraulic lithotripsy (EHL) (2.9% vs. 1.9%, P = 1.000), or postoperative hospital stay (P = 0.214). The incidence of postoperative complications was comparable between the two groups. During the follow-up period, none of the patients experienced biliary stricture, and 1 case of stone recurrence occurred in the elective group. CONCLUSIONS LCBDE with primary closure for choledocholithiasis patients with non-severe acute cholangitis has the equivalent efficacy and morbidity to elective surgery. Primary closure after LCBDE is a safe and feasible option for choledocholithiasis patients with non-severe acute cholangitis.

Abstract
Purpose China has the largest cancer population globally. Surgery is the main choice for most solid cancer patients. Intraoperative fluorescence molecular imaging (FMI) has shown its great potential in assisting surgeons in achieving precise resection. We summarized the typical applications of intraoperative FMI and several new trends to promote the development of precision surgery. Methods The academic database and NIH clinical trial platform were systematically evaluated. We focused on the clinical application of intraoperative FMI in China. Special emphasis was placed on a series of typical studies with new technologies or high-level evidence. The emerging strategy of combining FMI with other modalities was also discussed. Results The clinical applications of clinically approved indocyanine green (ICG), methylene blue (MB), or fluorescein are on the rise in different surgical departments. Intraoperative FMI has achieved precise lesion detection, sentinel lymph node mapping, and lymphangiography for many cancers. Nerve imaging is also exploring to reduce iatrogenic injuries. Through different administration routes, these fluorescent imaging agents provided encouraging results in surgical navigation. Meanwhile, designing new cancer-specific fluorescent tracers is expected to be a promising trend to further improve the surgical outcome. Conclusions Intraoperative FMI is in a rapid development in China. In-depth understanding of cancer-related molecular mechanisms is necessary to achieve precision surgery. Molecular-targeted fluorescent agents and multi-modal imaging techniques might play crucial roles in the era of precision surgery.

Abstract
BACKGROUND Anti-reflux surgery (ARS) has known long-term complications, including dysphagia, bloat, and flatulence, among others. The factors affecting the development of post-operative dysphagia are poorly understood. We investigated the correlation of intra-operative esophagogastric junction (EGJ) characteristics and procedure type with post-operative dysphagia following ARS. METHODS Robotic ARS was performed on 197 consecutive patients with pathologic reflux utilizing EndoFLIP™ technology. Intraoperative EGJ measurements including distensibility index (DI), cross-sectional area (CSA), and high-pressure zone (HPZ) length were collected. Dysphagia was assessed pre-operatively and at 3 months post-operatively. RESULTS The median pre-operative DI for all procedures was 2.6 (IQR 1.6-4.5) mm2/mmHg. There was no difference in post-operative DI between procedures [Hill: 0.9 (IQR 0.7-1.1) mm2/mmHg, Nissen: 1.0 (IQR 0.7-1.4) mm2/mmHg, Toupet: 1.2 (IQR 0.8-1.5) mm2/mmHg, Linx: 1.0 (IQR 0.7-1.2) mm2/mmHg, p = 0.24], whereas post-operative HPZ length differed by augmentation type [Hill: 3 (IQR 2.8-3) cm, Nissen: 3.5 (IQR 3-3.5) cm, Toupet: 3 (IQR 2.5-3.5) cm, Linx: 2.5 (IQR 2.5-3) cm, p = 0.032]. Eighty-nine patients (45.2%) had pre-operative dysphagia. Thirty-two patients (27.6%) reported any dysphagia at their 3-month post-operative visit and 12 (10.3%) developed new or worsening post-operative dysphagia [Hill: 2/18 (11.1%), Nissen: 2/35 (5.7%), Toupet: 4/54 (7.4%), Linx: 4/9 (44.4%), p = 0.006]. The median pre-operative and post-operative DI of patients who developed new or worsening dysphagia was 2.0 (IQR 0.9-3.8) mm2/mmHg and 1.2 (IQR 1.0-1.8) mm2/mmHg, respectively, and that of those who did not was 2.5 (IQR 1.6-4.0) mm2/mmHg and 1.0 (IQR 0.7-1.4) mm2/mmHg (p = 0.21 and 0.16, respectively). CONCLUSIONS Post-operative DI was similar between procedures, and there was no correlation with new or worsening post-operative dysphagia. Linx placement was associated with higher rates of new or worsening post-operative dysphagia despite a shorter post-procedure HPZ length and similar post-operative DI when compared to other methods of LES augmentation.
