Objective To explore the operative main point and clinical effects of laparoscopic treatment for hepatic cyst. Methods Between August 2006 and April 2009, Forty-eight cases of laparoscopic treatment for hepatic cyst were performed, and the data were analyzed retrospectively. Of these treatments, there were laparoscopic fenestration (46 cases) and laparoscopic anatomical resection of left hepatic lobe (2 cases). Of the patients, there were solitary cyst (41 cases) and multiple cyst (7 cases). Results Fortyeight cases all performed laparoscopic treatment successfully. There were no converting to open operation, no biliary leakage and no bleeding. Except for resection of left hepatic lobe, the operating time was 30 -96 minutes (mean, 45 minutes), the intraoperative blood loss was 10 -90 mL (mean, 26 mL) and the postoperative hospital stay was 3 - 9 days (mean, 5 days). All the 48 patients were followed up for 6 to 36 months (mean, 32 months), 2 cases were found recurrence. Conclusions Affluent experience and proper standard of operation are key points for avoiding recurrence and complication in laparoscopic treatment for hepatic cyst. Laparoscopic treatment for hepatic cyst is safe, characterized by less pain and rapid recovery.

Objective To explore the surgical skills and clinical efficacy of laparoscopic splenectomy (LS). Methods The operative duration, perioperative blood loss and postoperative complications were determined in 42 patients receiving LS in our hospital from October 2006 to May 2008 were retrospectively analyzed. Of the 42 patients, 12 suffered from splenomegaly due to blood disease, 1 from splenic tuberculosis, 1 from splenic cyst, 4 from traumatic splenic rupture,1 from malignant lymphoma and 23 from hypersplenism due to portal hypertension. Results LS was successfully performed in all the 42 patients. The mean perioperative blood loss was (300±110.60)ml, average operative duration (170±45.65) min (60-260 min) and mean postoperative inhospitalization duration (8.10±3.52)d. There was no severe complication after the operation. Conclusion For most types of splenic diseases, LS is safe and feasible. It is crucial to manage the splenic pedicle according to disease type, size, morphology and splenic hilus.

Objective:To investigate the surgical effect of various circulatory pathways on replantation of severed distal segments of digits.Methods:From June 2017 to June 2023, a total of 137 patients (162 digits) who received digit replantation surgery in the Department of Trauma Orthopaedics and Microsurgery of Guilin People's Hospital were retrospectively studied. The patients were 82 males (97 digits) and 55 females (65 digits) aged 11.0 months to 51.0 years old, with 31.7 years old in average. The injured digits were 36 thumbs, 43 index fingers, 32 middle fingers, 28 ring fingers and 23 little fingers. Causes of injury: 55 digits were of electric saw, 68 of sharp object cut, 26 of twisting crush and 13 of degloving injury. According to the circulatory pathways, 66 patients (88 digits) were assigned to a physiological replantation group (PRG), 50 patients (53 digits) to an arterio-venolisation group (AVG) and 21 patients (21 digits) to a nail bed bloodletting group (NBG). Functional recovery was evaluated according to the Evaluation Standard of Severed Finger Functional of Hand Surgery of Chinese Medical Association. Analysis of variance or chi-square test was employed to analyse the age, gender, time from injury to surgery, surgery time, incidence of vascular compromise of the replanted digit, survival rate, score of functional recovery of the affected digit at 6 months after surgery, and incidence of postoperative complications in each group. P<0.05 was considered statistically significant. Results:All patients were included in the 6-10 months of postoperative follow-up, with an average of 7.2 months. Regarding the score of functional recovery of affected digit according to the Evaluation Standard of Severed Finger Functional of Hand Surgery of Chinese Medical Association, PRG (86.3 points±7.9 points) was higher than that of NBG (78.3 points±11.2 points) and AVG (70.7 points±8.6 points), with statistically significant differences ( P<0.05 for both). In terms of the incidence of vascular compromise, PRG (3 digits for 3.4%) was lower than that of NBG (1 digit for 4.8%) and AVG (6 digits for 11.3%), with statistically significant differences ( P<0.05 for both). Of the survival rate, PRG (81 digits for 92.0%) was superior to that of NBG (18 digits for 85.7%) and AVG (42 digits 79.2%), with statistically significant differences ( P<0.05 for both). While of the incidence of postoperative complications, PRG (12.6%) was lower than that of AVG (17.1%) and NBG (21.2%), with statistically significant differences ( P<0.05 for both). Conclusion:For a severed distal segment of digit, the physiological replantation is preferred. For the digit with undetectable return veins, effective replantation can be achieved by the arterio-venolisation or nail bed exsanguination.

Objective: Previous research has explored a variety of mental disorders associated with Internet Gaming Disoder (IGD) and Social Media Addiction (SMA). To date, few studies focused on the network characteristics and investigated mood and sleep symptoms across SMA and IGD of adolescence at a group-specific level. This study aims to identify different characteristics of IGD and SMA and further determine the group-specific psychopathology process among adolescents. Methods: We conducted a cross-sectional study to recruit a cohort of 7,246 adolescents who were scored passing the cutoff point of Internet Gaming Disorder Scale-Short Form and Bergen Social Media Addiction Scale, as grouped in IGD and SMA, or otherwise into the control group. Patient Health Questionnaire-9, Generalized Anxiety Disorder 7-item, and Pittsburgh Sleep Quality Index were assessed for the current study, and all assessed items were investigated using network analysis. Results: Based on the analytical procedure, the participants were divided into three groups, the IGD group (n=789), SMA group (n=713) and control group (n=5,744). The edge weight bootstrapping analysis shows that different groups of networks reach certain accuracy, and the network structures of the three groups are statistically different (pcontrol-IGD=0.004, pcontrol-SMA<0.001, pIGD-SMA<0.001). The core symptom of SMA is “feeling down, depressed, or hopeless”, while IGD is “feeling tired or having little energy”. Conclusion Although IGD and SMA are both subtypes of internet addiction, the psychopathology processes of IGD and SMA are different. When dealing with IGD and SMA, different symptoms should be addressed.
