With the continuous development of laparoscopic hepatectomy for the treatment of hepatocellular carcinoma in recent years, laparoscopic anatomical hepatic segmentectomy has become increasingly improved, including anatomical segmentectomy, subsegmentectomy and combined segmentectomy. The above surgical procedures involve a variety of technical means, requiring the surgeon to be familiar with intrahepatic anatomy and possess extensive experience in ultrasound technology and laparoscopic surgery. This article discussed the key techniques of laparoscopic anatomical hepatic segmentectomy for hepatocellular carcinoma based on our clinical practice.

Objective:To assess the safety and feasibility of hepatic pedicle-first approach laparoscopic anatomical hepatectomy for central segments.Methods:The clinical data of 19 patients with hepatocellular carcinoma who underwent hepatic pedicle-first approach laparoscopic anatomical hepatectomy for the central segments in the Faculty of Hepato-Pancreato-Biliary Surgery, Chinese PLA General Hospital from September 2020 to January 2023 were retrospectively analyzed. In this procedure, hepatic pedicles of the central segments were divided first to delineate the ischemic demarcation and guide the liver parenchymal transection. The methods of operation, operation time, intraoperative blood loss, postoperative complications and hospital-stay were analyzed.Results:Hepatic pedicle-first approach laparoscopic anatomical hepatectomy for the central segments was successfully performed in all patients, including 5 cases of segment Ⅳ, 2 cases of segment Ⅳ+ Ⅷ, 3 cases of segment Ⅳ+ ventral segment Ⅷ, 3 cases of segment Ⅳa+ Ⅴ+ Ⅷ and 6 cases of segment Ⅴ+ Ⅷ. The mean operation time, intraoperative blood loss and postoperative hospital stay was (253.1±86.1) min, [ M( Q1, Q3)] 100.0(100.0, 250.0) ml, and (5.1±1.2) d respectively. There was no intraoperative blood transfusion and postoperative complications. Conclusion:Hepatic pedicle-first approach can help delineate the segemental demarcation in laparoscopic anatomical hepatectomy for the central segments, which is technically feasible and worth more practice.

Objective:To compare the application effect of remote intelligent rehabilitation system and conventional rehabilitation in rehabilitation of patients with rotator cuff injury following minimally invasive arthroscopic surgery.Methods:A retrospective cohort study was used to analyze the clinical data of 47 patients with rotator cuff injury admitted to Xinhua Hospital, Shanghai Jiao Tong University School of Medicine from January to July 2022, including 18 males and 29 females; aged 45-65 years [(56.7±6.3)years]. All patients underwent minimally invasive arthroscopic surgical repair of rotator cuff rupture. After surgery, 25 patients underwent self-rehabilitation with conventional education (conventional rehabilitation group), and 22 patients underwent systematic rehabilitation with remote intelligent rehabilitation system (remote rehabilitation group). Constant shoulder score, University of California at Los Angeles (UCLA) shoulder score, self-rating anxiety scale (SAS) score, self-rating depression scale (SDS) score and visual analog score (VAS) were compared between the two groups on the day of admission, 4, 8, 12 weeks after surgery and at the last follow-up. Shoulder MRI was applied at 6 weeks after surgery to compare the degree of intra-articular effusion and bone marrow edema between the two groups. The shoulder range of motion of the two groups was compared at 12 weeks after operation. The satisfaction with the rehabilitation of the two groups was compared at the last follow-up.Results:All the patients were followed up for 6-10 months [(8.5±2.2)months]. There was no significant difference in Constant shoulder score, UCLA shoulder score, SAS score, SDS score and VAS between the two groups on the day of admission (all P>0.05). There was no significant difference in Constant score, UCLA score and SAS score between the two groups at 4 weeks after surgery (all P>0.05). The values of SDS score and VAS at 4 weeks after surgery were (31.8±6.6)points and (3.6±1.1)points in the remote rehabilitation group, which were better than those in the conventional rehabilitation group [(40.5±5.6)points and (4.7±1.3)points] (all P<0.05). The values of Constant score, UCLA score, SAS score, SDS score and VAS at 8 weeks after surgery were (62.5±5.5)points, (18.5±3.3)points, (20.5±4.7)points, (22.5±4.6)points and (2.5±0.6)points in the remote rehabilitation group, which were better than those in the conventional rehabilitation group [(41.3±4.7)points, (15.3±3.1)points, (28.5±4.8)points, (38.5±3.7)points and (3.3±1.3)points] ( P<0.05 or 0.01). The values of Constant score, UCLA score, SAS score and SDS score at 12 weeks after surgery were (85.4±6.4)points, (32.2±3.8)points, (13.6±2.8)points and (18.4±3.9)points in the remote rehabilitation group, which were better than those in the conventional rehabilitation group [(60.3±6.7)points, (25.2±4.1)points, (21.5±4.9)points and (26.7±6.6)points] (all P<0.05), while there was no significant difference in VAS between the two groups ( P>0.05). At the last follow-up, there were no significant differences in Constant score, UCLA score, SAS score, SDS score and VAS between the two groups (all P>0.05). MRI of the shoulder joint at 6 weeks after surgery indicated that the degree of intra-articular effusion in the shoulder joint and bone marrow edema of the proximal humerus in the remote rehabilitation group was significantly reduced than that in the conventional rehabilitation group. At 12 weeks after surgery, the remote rehabilitation group had better shoulder range of motion than the conventional rehabilitation group ( P<0.05 or 0.01). At the last follow-up, the satisfaction with the rehabilitation of the remote rehabilitation group was better than that of the conventional rehabilitation group ( P<0.01). Conclusion:For patients with rotator cuff injury who undergo minimally invasive arthroscopic surgery, postoperative application of remote intelligent rehabilitation system, in comparison with the conventional rehabilitation system, can help to facilitate shoulder function recovery, anxiety and depression improvement and pain relief in the early stage, reduce shoulder soft tissue and bone marrow edema of the shoulder, and increase shoulder range of motion and patients′ satisfaction with the rehabilitation.

Objective:To analyze the epidemiological characteristics and transmission chain of an epidemic of COVID-19 in Haidian district, Beijing.Methods:Descriptive epidemiological method was used to analyze the epidemiological characteristics of the epidemic, and field investigation and big data technology were used to analyze the transmission chain of the epidemic.Results:From April 27 to May 13, 2022, an epidemic of COVID-19 occurred in Haidian district. The strains isolated from the cases were identified by whole genome sequencing as Omicron variant (BA.2.2 evolutionary branch). A total of 38 infection cases were detected, including 34 confirmed cases and 4 asymptomatic cases. Most cases were mild ones (88.2%), no severe, critical or death cases occurred. The early clinical symptoms were mainly sore throat (50.0%) and cough (29.4%). The epidemic lasted for 17 days, resulting in 7 generations of the cases and involving 3 community transmissions, 2 working place transmissions and 8 family transmissions; the main infection routes were co-residence (47.6%) and co-space exposure (31.6%). The intergenerational interval M( Q1, Q3)was 3 (1, 6) days. The overall secondary attack rate was 1.5% (37/2 482), and the family secondary attack rate was 36.7% (18/49). Conclusions:The cases in this COVID-19 epidemic caused by Omicron variant had mild clinical symptoms, but the case clustering in families and communities was obvious, the transmission was rapid, and the risk for co-space exposure was high. It is necessary to use information technology to identify close contacts in the local population for the rapid and effective blocking of the epidemic spread.

Objective:To explore the strategy and efficacy using minimally invasive treatment for grade Ⅲ&Ⅳ blunt pancreatic injuries.Methods:Retrospective data retrieved from medical records of 13 patients with grade Ⅲ&Ⅳ blunt pancreatic injuries who underwent minimally invasive treatment at the Chinese PLA General Hospital from July 2011 to June 2019 were analysed. There were 10 males and 3 females, aged (38±9) years. Minimally invasive treatment included percutaneous catheter drainage (PCD) and minimal-access retroperitoneal pancreatic necrosectomy (MARPN). Date from enrolled patients were anylsed.Results:There were 9 patients suffering from grade Ⅲ injuries and 4 patients suffering from grade Ⅳ injuries. On initial conservative treatment of these 13 patients, all developed local complications. The local complications were treated using minimally invasive treatment strategies: 13 patients underwent PCD. The median intervention time for PCD was 25 days after trauma; 10 patients were further treated with MARPN, and the median intervention time of MARPN was 41 days after trauma. Twelve patients recovered well and were discharged home. One patient died. The mortality rate was 7.7% (1/13). The median postoperative hospital stay was 19 days.Conclusion:For patients with pancreatic grade Ⅲ&Ⅳ injuries who were hemodynamically stable and had no other associated gastrointestinal injuries, initial conservative treatment, followed by subsequent minimally invasive treatment based on MARPN technology could be used to treat local complications.

Objective:To investigate the effect of passive motion and immobilization on shoulder function early after arthroscopic repair of rotator cuff tears.Methods:A retrospective case-control study was conducted to analyze the clinical data of 78 patients with rotator cuff tear admitted to Xinhua Hospital, Shanghai Jiaotong University School of Medicine from January 2016 to December 2017. There were 36 males and 42 females, aged 35-78 years [(62.7±3.2)years]. There were 36 patients with medium-sized tears (1-3 cm), 31 with small tears (<1 cm), and 11 with partial articular supraspinatus tendon avulsion (PASTA). All patients underwent arthroscopic rotator cuff repair. Forty-three patients started rehabilitation exercise immediately after operation (motion group). Thirty-five patients were immobilized with shoulder abduction brace for 6 weeks, and started rehabilitation exercise at week 7 (immobilization group). The range of motion, visual analogue pain score (VAS), simplified shoulder joint function test (SST) and Constant shoulder joint score were compared between the two groups before surgery, 6 weeks, 3 months and 12 months after surgery. The healing results were assessed by ultrasound 12 months after surgery. Complications were observed.Results:All the patients were followed up for 12-16 months [(13.7±1.3)months]. There were 7 patients with shoulder joint stiffness in each group (motion group: 16%, immobilization group: 20%) ( P<0.05). There were no significant differences between the two groups in VAS, SST or Constant score at postoperative 6 weeks, 3 months and 12 months ( P>0.05). The forward flexion and external rotation with the arm at the side in immobilization group was (124.9±12.9)° and 25(20, 30)° at postoperative 6 weeks, significantly improved in motion group [(136.6±16.7)°, 30(25, 40)°] ( P<0.05). There were no significant differences between the two groups in forward flexion and external rotation with the arm at the side at postoperative 3 and 12 months ( P>0.05). There were no significant differences between the two groups in internal rotation at postoperative 6 weeks, 3 months, and 12 months ( P>0.05). All rotator cuffs were healed verified by ultrasound at postoperative 12 months. No infection or implant displacement occurred after operation. Conclusions:For arthroscopic repair of medium-sized tears, small tears and PASTA, early postoperative rehabilitation exercises have advantage in improving range of motion only at early stage when compared to immobilization, which disappears with time. Moreover, the two methods have no significant differences in improving postoperative pain and shoulder function.

Objective:To study the use of left renal vein as a graft vessel in reconstruction after portal vein/superior mesenteric vein (PV-SMV) resection in pancreaticoduodenectomy.Methods:A retrospective study was conducted on 5 of these patients who underwent surgery from July 2008 to December 2017 at Chinese PLA General Hospital. The operative, complication and follow-up data were analysed.Results:There were 4 males and 1 female, with an average age of 57 (33-72) years. The mean operative time was 6.8 (5.4-9.1) h and the mean tumor size was 3.8 (2.8-4.8) cm. The average length of the PV-SMV defect left after resection was 3.8 (3.2-4.6) cm. The average length of the left renal vein used was 3.4 (3.0-4.1) cm. The operations were carried out in 3 patients with pancreatic cancer and in 2 patients with colon cancer pancreatic metastasis. The average postoperative hospital stay was 12 (10-25) days. Perioperative complications included 1 patient each with ascites, diarrhea and delayed gastric emptying. The creatinine levels ranged from 70-98 μmol/L preoperatively, with a transient creatinine rise to 80-156 μmol/L after operation and became 62-107 μmol/L upon discharge from hospital. The follow-up time was 4.3-17.8 months. Two patients died of recurrence/metastasis at 14.2 and 17.8 months after surgery.Conclusions:The left renal vein has the appropriate diameter and rich collateral branches. It has a sufficient length and it is conveniently located in the surgical field. This study showed that there was a minimal effect on renal function after its excision, and it can be used as a graft vessel for reconstruction in pancreaticoduodenectomy after PV-SMV resection.
