Objective:To explore the safety and effectiveness of laparoscopic local pancreatectomy in the treatment of cystic neoplasms of pancreatic head.Methods:Retrospective analysis was conducted of data on patients with pancreatic head cystic neoplasms who received laparoscopic surgery at the Department of Hepatobiliary Surgery, the Second Hospital of Hebei Medical University from February 2017 to October 2022. A total of 83 patients were enrolled, including 30 males and 53 females, aged (43.7±16.7) years old. All patients were divided into an observation group ( n=55) and a control group ( n=28) based on different surgical procedures. The observation group underwent laparoscopic local pancreatectomy (laparoscopic duodenum-preserving pancreatic head resection or laparoscopic enucleation), while the control group underwent laparoscopic pancreaticoduodenectomy (LPD). The age, gender, body mass index, postoperative hospital stay, proportion of discharged patients with drainage tubes, surgical time, intraoperative blood loss, intraoperative blood transfusion rate, and fistula were compared between two groups. Results:All patients successfully completed the surgery, and there were no cases of conversion to laparotomy or perioperative deaths. There was no statistically significant difference in age, male proportion, body mass index, postoperative hospital stay, and discharge rate with drainage tube between the two groups of patients (all P>0.05). The observation group had a surgical time of (194.4±114.0) min, intraoperative bleeding of 50 (50, 200) ml, and intraoperative blood transfusion rate of 5.5%(3/55), all of which were better than that of the control group, (380.0±71.6) min, 200 (100, 400) ml, and 32.1%(9/28), with statistical significance (all P<0.05). Among them, the B/C fistula rates in the laparoscopic local pancreatectomy group and LPD group were 12.7%(7/55) and 10.7%(3/28) ( P=0.790), respectively. Conclusion:Compared with traditional LPD, laparoscopic local pancreatectomy can shorten surgical time, reduce intraoperative bleeding, and lower intraoperative blood transfusion rate. And there is no significant disadvantage in the B or C grade fistula.

Objective:To study the optional timing of removal of abdominal drains after laparoscopic pancreaticoduodenectomy (LPD) based on the enhanced recovery after surgery (ERAS) concept versus conventional practice.Methods:The clinical data of patients who underwent LPD at the Second Hospital of Hebei Medical University and the First Hospital of Hebei Medical University from January 2020 to June 2021 were retrospectively analyzed. Of 127 patients included in this study, there were 74 males and 53 females, with age of (58.68±8.65) years old. Then patients were divided into two groups according to the timing of removal of abdominal drains based on the ERAS concept (the ERAS group, n=61), and conventional clinical practice (the control group, n=66). The abdominal drains in the ERAS group was removed based on 2 criteria: (1) no discharge of bile, gastrointestinal contents, pus, and active bleeding in the abdominal drains on the first day after operation; (2) amylase in abdominal drainage fluid was less than 5 000 U/L on the first day after operation. The abdominal drains in the control group was removed after meeting the following criteria: (1) no discharge of bile, gastrointestinal contents, pus, and active bleeding in the abdominal drains; (2) from the first day after operation, amylase levels in the drain fluid was measured once everyday, and the concentrations of the amylase were less than 5 000 U/L for 2 consecutive days; (3) the volume of drainage was less than 100 ml/24 h. The postoperative recovery and other clinical data of the two groups were also compared. Results:LPD was successfully performed in the 2 groups, and there was no perioperative death. The timing of removal of abdominal drains [1 vs. 7(5, 9) d], the first passage of flatus [3(2, 4) vs. 3(3, 5) d] and the postoperative hospital stay [14(10, 18) vs. 17(14, 22) d] in the ERAS group were significantly shorter than the control group, and the hospitalization cost was also significantly less [10.33(9.64, 11.52) vs. 11.22(10.38, 13.58) wan yuan] (all P<0.05). Conclusion:The ERAS concept in guiding the timing of removal of abdominal drains after LPD was safe and feasible. The enhanced recovery after surgery concept is worthy of further promotion and application.

Cognitive impairment often occurs in elderly patients with heart failure.In this paper, we reviewed the possible mechanism of cognitive impairment in elderly patients with heart failure.The possible pathological mechanism of cognitive impairment in elderly patients with heart failure was discussed from the aspects of decreased cardiac output, renal damage, atrial fibrillation, inflammatory reaction, neuroregulation, depression and high homocysteine level, and the effect of cognitive impairment on heart failure was also summarized, so as to improve both the clinicians' awareness of cognitive impairment and the level of diagnosis and treatment in elderly patients with heart failure.

Objective:To investigate the application value of laparoscopic pancreatic tumor enucleation (LapEN).Methods:The retrospective and descriptive study was conducted. The clinical data of 47 patients who underwent LapEN in Second Hospital of Hebei Medical University from September 2016 to June 2022 were collected. There were 18 males and 29 females, aged (49±12)years. Observa-tion indicators: (1) surgical situations; (2) postoperative complications; (3) postoperative recovery; (4) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( Q1, Q3) or M(range). Count data were described as absolute numbers. Results:(1) Surgical situations. All 47 patients underwent LapEN successfully, with the operation time as (135±19)minutes and the volume of intraoperative blood loss as 100(50,100)mL. (2) Postoperative complications. Of the 47 patients, there were 12 patients with postoperative pancreatic fistula, 3 patients with postoperative abdominal infection, 1 case with postoperative hemorrhage, 1 case with postoperative gastric emptying disorder. (3) Postoperative recovery. Of the 47 patients, there were 13 cases with pancreatic solid pseudopapillary neoplasm, 12 cases with insulinoma, 11 cases with pancreatic serous cystadenoma, 7 cases with pancreatic intraductal papillary mucinous neoplasm (branched type), 4 cases with pancreatic mucinous cyst-adenoma. The tumor diameter of 47 patients was 1.9(1.6,2.3)cm and all patients with R 0 resection. There was no patient with perioperative death in the 47 patients. The postoperative duration of hospital stay and total hospital expenses of 47 patients was (13±4)days and (6.8±1.2) ten thousand yuan, respectively. (4) Follow-up. All 47 patients were followed up for 14(range, 8?18)months. None of the 47 patients had new onset diabetes or situations required postoperative exocrine replacement therapy, and no patient died. Conclusion:LapEN is safe and feasible for patients with pancreatic benign tumor or low potential malignancy.

There are many methods of pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy. It is suggested that the formation of "sinus healing" by pancreaticojejunostomy benefits pancreatic juice extravasation and intestinal fluid reflux. The healing of fibrous layer is based on mechanical connection, and there are various forms of connection. Our team summarized the experience since laparoscopic pancreaticoduodenectomy, using the improved "double needle pancreaticoenterostomy" and combined with "variable diameter measurable drainage catheter" to support the pancreatic duct to form "sinus healing" at the pancreaticointestinal anastomosis.The main techniques and experiences are summarized as follows.

Objective:To study the retrocolonic approach for laparoscopic pancreaticoduodenec-tomy (LPD).Methods:The clinical data of 53 patients who underwent LPD using the retrocolonic approach at the Second Hospital of Hebei Medical University from January 2019 to December 2021 were analyzed retrospectively. There were 36 males and 17 females, aged (61.9±8.8) years old. The operation time, intraoperative bleeding and postoperative complications were analysed.Results:LPD was successfully performed in 53 patients via the retrocolonic approach. The operation time was (285.7±49.8) min, and the resection time for specimens was (120.0±10.5) min. The median intraoperative blood loss was 200 ml and blood loss ranged from 50 to 800 ml. Among the 53 patients, 3 patients underwent combined portal vein resection and reconstruction (end-to-end anastomosis). The operation time was 300, 325 and 385 min, respectively, and the intraoperative blood loss was 400-800 ml. During the operation, 5 patients (9.43%) had transection of the middle colonic artery and underwent resection of part of the transverse mesocolon due to invasion of the transverse mesocolon by tumours. Postoperative complications occurred in 5 patients (9.43%), including 4 patients with pancreatic fistula and 1 patient with hemorrhage and with delayed gastric emptying. The postoperative passage of first flatus was (5.40±1.14) days in 5 patients with transection and (2.92±1.03) days in 48 patients without transection of the middle colonic artery. All patients were discharged home successfully. The postoperative pathological results showed all patients to achieve R 0 resection. Conclusion:Laparoscopic pancreaticoduodenectomy via the retrocolonic approach was safe and feasible for patients with a large duodenal tumor, pancreatic head uncinate process tumor with or without invasion of the portal vein and mesenteric vessels.

Objective:To study the safety and feasibility of laparosocpic left-liver-first anterior radical modular orthotopic right hemihepatectomy (Lap-Larmorh) in treatment of Bismuth-Corlette type Ⅲa hilar cholangiocarcinoma.Methods:From June 2020 to April 2022, 13 patients with Bismuth-Corlette type Ⅲa hilar cholangiocarcinoma underwent Lap-Larmorh at the Department of Hepatobiliary Surgery of the Second Hospital of Hebei Medical University. There were 8 males and 5 females, aged (60.9±8.4) years. The operation time, intraoperative blood loss, complications and postoperative survival were analyzed.Results:Five patients were treated with percutaneous transhepatic cholangial drainage to reduce jaundice before surgery. All 13 patients successfully underwent the Lap-Larmorh and there was no conversion to laparotomy. The operative time was [ M( Q1, Q3)] 390.0 (355.0, 435.0) minutes, and the intraoperative blood loss was [ M( Q1, Q3)] 800.0 (300.0, 1 100.0) ml. Postoperative complications occurred in 4 patients with pleural effusion, and 1 patient had portal vein thrombosis associated with pleural effusion, who was managed successfully using low molecular weight heparin sodium anticoagulation therapy and pleural effusion tapping. The postoperative hospital stay was (12.5±5.5) days, and there was no perioperative death. Intraoperative frozen pathology showed 12 patients with left hepatic duct with negative margins, and 1 patient with moderate dysplasia. Postoperative paraffin pathology showed 12 patients with bile duct adenocarcinoma, 1 patient with bile duct mucinous adenocarcinoma, 2 patients with tumors of high differentiation, 10 patients with moderate differentiation, and 1 patient with poor differentiative. The R 0 resection rate was 100.0% (13/13) and the tumor diameter was (2.9±0.9) cm. Follow-up by telephone or outpatient clinics after operation showed 1 patients to be lost to follow-up. The 1-year survival rate after operation was 66.7% (8/12). Conclusion:For Bismuth-Corlette type Ⅲa hilar cholangiocarcinoma, the new laparoscopic approach of Lap-Larmorh was safe and feasible.

Objective:To study the safety and therapeutic effects of the modified pancreaticogastrostomy based on the concept of " Hong's one-stitch method" in digestive tract reconstruction in pancreatic surgery.Methods:The clinical data of 44 patients who underwent modified pancreaticogastresstomy at the Department of Hepatobiliary Surgery, the Second Hospital of Hebei Medical University from May 2022 to October 2022 were analyzed retrospectively. There were 23 males and 21 females , with a median age of 54 years old (range 18 to 70 years old). The operation time, intraoperative blood loss, postoperative condition and complications were analysed.Results:All the 44 patients completed the operation successfully. There were 29 patients who underwent laparoscopic pancreaticoduodenectomy, 11 patients laparoscopic duodenum-preserving pancreatic head resection, 1 patient laparoscopic central pancreatectomy, and 3 patients open pancreaticoduodenectomy. The time required for the pancreaticogastrostomy was (15.4±1.0) min in laparoscopic surgery, and (9.1±0.5) min in open surgery. There were 2 patients who developed grade A pancreatic fistula (4.55%, 2/44) and 7 patients gastric emptying disorder (15.91%, 7/44). There were no grade B or C pancreatic fistula, biliary fistula, gastrointestinal anastomotic fistula, abdominal infection, postoperative bleeding and perioperative death.Conclusion:The modified pancreaticogastrostomy for digestive tract reconstruction in pancreatic surgery was safe and reliable. It effectively reduced the incidence of postoperative pancreatic fistula and improved prognosis of patients.

At present,there are many difficulties in the diagnosis and treatment of acute vestibular syndrome(AVS).For example,complex and difficult identification of the cause of disease,uneven diagnosis and treatment levels of clinical doctors,weak humanistic care awareness,lack of communication skills,intrinsic affinity and other reasons,which make it difficult for AVS patients in the process of diagnosis and treatment,and cannot receive timely and effective treatment,resulting in an exacerbation of doctor-patient conflicts.Therefore,it is recommended to explore new paths of AVS diagnosis and treatment work using the humanistic care concept,respect each other between doctors and patients,build a team of medical staff with the value orientation of"humanistic care",and promote the organic unity of theory and practice of"humanistic care",with a view to better promoting the implementation of AVS diagnosis and treatment work,helping more patients rebuild confidence,enhancing quality of life,and improving the doctor-patient relationship.

Objective To investigate the efficacy and safety of camrelizumab monoclonal antibody combined with molecular-targeted therapy in elderly patients with unresectable or advanced hepatocellular carcinoma(HCC).Methods A retrospective analysis was performed for the patients with unresectable/advanced HCC who attended six hospitals from January 1,2019 to March 31,2021,and all patients received camrelizumab monoclonal antibody treatment,among whom 84.8%also received targeted therapy.According to the age of the patients,they were divided into elderly group(≥65 years)and non-elderly group(＜65 years).The two groups were assessed in terms of overall survival(OS),progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),and immune-related adverse events(irAE).The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups;the independent samples t-test was used for comparison of normally distributed continuous data,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups.The Kaplan-Meier method was used for survival analysis,and the log-rank test was used for comparison of survival curves.Univariate and multivariate Cox proportional hazards regression analyses were used to determine the independent influencing factors for PFS and DCR at 6 months.Results A total of 99 HCC patients were enrolled,with 27 in the elderly group and 72 in the non-elderly group.The elderly group had an OS rate of 67.8%,an ORR of 44.4%,and a DCR of 74.1%at 12 months and a median PFS of 6.4(95%confidence interval[CI]:3.0-12.4)months,with no significant differences compared with the non-elderly group(all P＞0.05).The median OS was unavailable for the elderly group,while the non-elderly group had an OS of 18.9(95%CI:13.0-24.8)months;there was no significant difference between the two groups(P=0.485).The univariate and multivariate Cox regression analyses showed that major vascular invasion(MVI)was an independent risk factor for PFS(hazard ratio[HR]=2.603,95%CI:1.136-5.964,P=0.024)and DCR(HR=3.963,95%CI:1.671-9.397,P=0.002)at 6 months,while age,sex,etiology of HBV infection,presence of extrahepatic metastasis,Child-Pugh class B,and alpha-fetoprotein＞400 ng/mL were not associated with PFS or DCR at 6 months.For the elderly group,the incidence rates of any irAE and grade 3/4 irAE were 51.9%and 25.9%,respectively,with no significant differences compared with the non-elderly group(P＞0.05),and skin disease was the most common irAE in both groups(39.4%).Conclusion Camrelizumab monoclonal antibody combined with molecular-targeted therapy has similar efficacy and safety in patients with unresectable/advanced HCC aged≥65 years and those aged＜65 years.MVI is associated with suboptimal response to immunotherapy and poor prognosis.
