RESUMEN
Objective:To evaluate the feasibility, safety and efficacy of indocyanine green (ICG) fluorescence imaging navigation combined with modified pancreaticogastrostomy in laparoscopic duodenum-preserving pancreatic head resection.Methods:The clinical data of 14 patients undergoing laparoscopic duodenum-preserving pancreatic head resection with indocyanine green fluorescence navigation technique combined with modified pancreaticogastrostomy from January 2019 to January 2022 in the Department of Hepatobiliary and Pancreatic Surgery, the First Hospital of Hebei Medical University were retrospectively analyzed, including 4 males and 10 females, aged (40.6±7.1) years. The operation time, intraoperative blood loss, postoperative complications and follow-up were recorded.Results:All 14 operations were successfully completed, and there was no intraoperative ICG allergic reaction. The intraoperative ICG staining facilitated the identification of common bile duct. The operation time was (325.71±23.00) min, and the time of modified pancreaticogastrostomy was (18.32±1.52) min. Intraoperative blood loss was 200 (150, 300) ml. There were no case of intraoperative blood transfusion. Postoperative complications include three cases of grade A pancreatic fistula, one of biliary fistula, and one of biliary stricture. All patients were followed up for one to 18 months, and the median follow-up time was 10 months. One patient had intermittent fever after operation. Magnetic resonance cholangiopancreatography showed biliary stricture in one patient one month after operation, which was managed by endoscopic biliary stent implantation.Conclusion:Indocyanine green fluorescence navigation is safe and feasible in laparoscopic duodenum-preserving pancreatic head resection. Combined with modified pancreaticogastrostomy, it helps skip the jejunal anastomosis and improve the efficiency of surgery.
RESUMEN
A rare instance of an aneurysmal bone cyst (ABC) in the wrist hamate of a 30-year-old male were reported in this case report. The patient exhibited a 1.5 cm mass on the dorsal ulnar side of the right wrist, which was non-tender, with normal overlying skin temperature and preserved wrist flexion. Radiographic evaluation revealed a deformed hamate with extensive cystic degeneration and minimal subchondral bone. Computed tomography (CT) scans highlighted clear osteolytic changes, including a visible bony crest. Magnetic resonance imaging (MRI) depicted mixed signal intensity on T1 and T2 weighted images. A biopsy indicated thinning and softening of the hamate's dorsal cortex, revealing eroded bone and dark red soft tissue. Histopathological analysis confirmed the diagnosis of an aneurysmal bone cyst. The patient underwent resection of the right wrist hamate, bone grafting from the iliac crest, and stabilization with Kirschner wire, resulting in fusion of the capitate-hamate and fourth and fifth carpometacarpal joints. The postoperative course involved immobilization with plaster for six weeks, and a 15-month follow-up indicated no recurrence. A review of the literature revealed that ABCs involving carpal bones are rare, predominantly occurring in individuals under 30 years of age. Clinical manifestations typically include wrist pain, occasional mild swelling, limited wrist mobility, and reduced hand strength. Radiological findings are characterized by osteolytic changes with MRI showing low T1WI and high T2WI signal intensity, and liquid levels on axial images. Treatment predominantly involves osteotomy or curettage with bone grafting. Diagnostic hallmarks include osteoclast-like multinucleated giant cells, ossified areas, and cystic cavities partitioned by fibrous septa. Our findings, consistent with the literature, suggest a favorable prognosis for carpal bone ABCs when treated appropriately.
RESUMEN
Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.
RESUMEN
Background Dentists are a high-risk population of work-related musculoskeletal disorders (WMSDs), where the body part with the highest prevalence is the neck. Objective To analyze potential influencing factors of neck pain among dentists, and explore a prediction model of neck pain in dentists. Methods Dentists from different hospitals in Fuzhou were selected as study subjects by stratified cluster sampling according to hospital characteristics (dental hospitals, general hospitals, and dental clinics). The basic information, presentation of WMSDs, and its influencing factors were investigated by using the Chinese version of Musculoskeletal Disorders Questionnaire and the Subjective Workload Assessment Technique. A total of 655 questionnaires were collected, of which 603 were valid, with an effective rate of 92.1%. Multiple logistic regression was used to analyze potential influencing factors of neck pain in dentists. A prediction model of neck pain of dentists was constructed by using neural network model, and the prediction efficiency of the model was evaluated. Results The neck was the body part with the highest prevalence (43.8%, 264/603) of WMSDs among dentists. The results of multiple logistic regression analysis showed that female (OR=2.709, 95%CI: 1.852-3.962, P <0.001), working age of 10-<20 years (versus <10 years, OR=3.836, 95%CI: 2.471-5.957, P<0.001), keeping head up or down for a long time (OR=8.492, 95%CI: 2.203-32.731, P=0.002), holding head sideways for a long time (OR=2.210, 95%CI: 1.376-3.550, P<0.001), maintaining the same sitting spot for a long time (OR=4.336, 95%CI: 2.192-8.579, P<0.001), and psychological load value ≥70 (versus <40, OR=1.901, 95%CI: 1.038-3.480, P=0.037) increased the risk of neck pain in dentists. Sufficient operating space (OR=0.507, 95%CI: 0.302-0.850, P=0.010) and doing some exercise during work break (OR=0.670, 95%CI: 0.453-0.991, P=0.045) reduced the risk of reporting neck pain among dentists. A neural network prediction model of dentists' neck pain was constructed with 1 hidden layer and 6 hidden layer neurons. The percentage of correct prediction of training set was 89.6%, and the percentage of correct prediction of test set was 83.9%. The order of importance of the independent variables included in the model were working age, holding head sideways for a long time, psychological load, etc. The result of neural network model of neck pain among dentists showed that the area under the curve of receiver operator characteristic (ROC) was 0.940 (95%CI: 0.922-0.958, P<0.001). When the maximum diagnostic value was determined by the ROC curve, the sensitivity was 84.8%, the specificity was 91.2%, and the Youden Index was 0.760. Conclusion Neck pain of dentists is affected by many factors, such as individual factors (gender and working age), ergonomic factors (keeping various postures and operations for a long time, operating space, etc.), psychological factors (different levels of psychological load) and so on. The neural network model can be used as a prediction tool to explore the risk of reporting neck pain among dentists.

RESUMEN
This article reviews the clinical studies about the treatment of allergic rhinitis （AR） with traditional Chinese medicine （TCM） in recent years. AR is a common and frequently occurring disease in the department of otolaryngology. The common manifestations of AR include nasal congestion， sneezing， runny nose， and nasal itching. AR， belonging to the category of rhinitis， is a dominant disease in the TCM treatment of otorhinolaryngologic diseases and head and neck diseases. The ancient literature has laid a solid theoretical basis on the etiology and pathogenesis of AR. According to the ancient literature， the theoretical basis， and their own experience， modern doctors classified the causes of AR into the disorders in Zang-fu organs and six meridians. Most of the explanations focus on the disorders in Zang-fu organs， especially the lung， spleen， and kidney. The clinical studies in this field mainly involve TCM treatment alone， integrated TCM and Western medicine treatment， and TCM external treatment. These therapies have good efficacy in the clinical treatment of AR. Among them， TCM treatment alone has significant advantages in alleviating the symptoms and nasal signs， declining the scores of related scales， and reducing the eosinophil count （EOS） of nasal secretions， with definite long-term efficacy. Integrated TCM and Western medicine treatment can complement with each other. The TCM external treatment methods include acupuncture， moxibustion， acupoint catgut embedding， acupoint application， and nasal irrigation with TCM， which are safe， simple， acceptable by patients and have good therapeutic effect. Finally， the clinical research status of TCM treatment of AR was summarized， and suggestions were put forward from three aspects： standardizing the clinical research protocol of TCM， encouraging pure TCM research， and exploring the mechanism of TCM treatment on the basis of frontier research achievements. This review aims to provide higher-level evidence for subsequent clinical research and promote the research on dominant AR diseases.

RESUMEN
Objective:To study the feasibility of a modified pancreatogastric anastomosis in laparoscopic duodenum preserving pancreatic head resection (LDPPHR).Methods:The clinical data of 25 patients with benign or low-grade malignant tumors of pancreatic head undergoing LDPPHR at the Second Hospital of Hebei Medical University from January 2019 to May 2023 were retrospectively analyzed, including 7 males and 18 females, aged (44.9±6.2) years old. According to the methods of pancreatic digestive reconstruction, patients were divided into the observation group ( n=10), who underwent the modified pancreatogastric anastomosis, and the control group ( n=15) who underwent conventional pancreaticojejunal anastomosis and jejuno-jejunal anastomosis. The general data, intraoperative pancreatic digestive reconstruction time, maximum levels of amylase in abdominal drainage within three days postoperatively, postoperative complications, and hospital stay were compared between the groups. Results:All procedures were performed successfully. The intraoperative pancreatic digestive reconstruction time was shorter in the observation group [(27.8±2.4) min vs. (45.8±3.6) min, P=0.010]. The intraoperative blood loss were comparable between the groups [(140.5±14.8) ml vs. (145.2±9.7) ml, P=0.843]. The maximum level of amylase in abdominal drainage within three days postoperatively was lower in the observation group [(809.1±185.5) U/L vs. (1 385.4±481.1) U/L, P=0.031]. No grade C pancreatic fistula or postoperative hemorrhage occurred in either group, and the incidence of grade B pancreatic fistula was lower in the observation group [20.0% (2/10) vs. 60.0% (9/15), P=0.048], with a shorter postoperative hospital stay [(7.9±1.3) d vs. (10.3±2.7) d, P=0.017]. No decrease of life quality or reoperation due to pancreatic fistula, hemorrhage or digestive tract malfunction occurred in either group within a median follow-up of 15.6 months. Conclusion:In LDPPHR, the modified pancreatogastric anastomosis could help shorten the pancreatic digestive reconstruction and lower the risk of postoperative pancreatic fistula.
RESUMEN
Objective:To observe the path and anatomic distribution of cutaneous branch of second dorsal metacarpal artery(SDMA) from the back of hand to the web of the fingers, and to explore the feasibility and clinical effect on the transfer of free flap of SDMA.Methods:Between June 2018 and September 2018, with perfusion of red latex, 22 hand specimens were dissected to explore the course, vessel calibre and distribution of cutaneous branches of SDMA, and to discover the existence of an innervation of cutaneous nerve in Department of Hand Surgery of Tangshan Second Hospital. Later on, from February 2019 to July 2020, 2 thumb pulp defects of 2 patients were reconstructed with the free flaps of SDMA. One defect was in the left thumb and the other in the right, both were male and compression injuries. Size of thumb pulp and a skin defect was at 3.5 cm×2.0 cm in 1 patient, and 2.0 cm×2.5 cm in the other. There was no neurovascular injury, but 1 patient had a distal phalangeal fracture and a nail bed laceration. The sizes of the flaps were 3.8 cm×2.3 cm and 2.8 cm×2.5 cm. Functional exercises started from 3 weeks after surgery. Patients attended postoperation follow up regularly by outpatient visit, telephone or internet interviews. Follow-up observations included the appearance, texture, sensory recovery of the flaps and thumb functions.Results:Multiple perforating branches (4-9 branches) were found from SDMA, which distributed in the distal 1/3 of SDMA in the anatomic study. It was found that the outer diameter of SDMA was 0.76 mm±0.25 mm at the intersection of extensor tendon of index finger and that of the digital web artery was 0.71 mm±0.12 mm. The length of digital web artery was 11.00 mm±1.27 mm. The 2 surgically transferred flaps were all survived. One patient showed the function of thumb in excellent with two-point discrimination (TPD) at 7.0 mm, at 18 months of follow-up. The other patient showed good thumb movement, soft and elastic skin of the flap and with a 7.5 mm in TPD, at 15 months of follow-up. According to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, the results of the 2 flaps were all excellent.Conclusion:The flap of SDMA has a constant cutaneous nerve and a long vascular pedicle with an ideal vessel size. It is suitable for free transfer and can be used to reconstruct soft tissue defects of thumb.
RESUMEN
Objective:To Explore the value of prolonging compression hemostasis time in reducing bleeding related complications after ultrasound guided percutaneous renal biopsy.Methods:A retrospective analysis was conducted on the clinical data of 405 patients who underwent ultrasound guided percutaneous renal biopsy at the Guangzhou First People′s Hospital. Three groups were divided based on whether to immediately compress and stop bleeding after renal biopsy and the compression time. The group A was treated with no compression and stop bleeding, the group B was treated with compression and stop bleeding for 2 minutes, and the group C was treated with compression and stop bleeding for 5 minutes. The patient′s gender, age, preoperative blood pressure, coagulation, hemoglobin, platelets, and other indicators were recorded. The number of punctures and the immediate postoperative perirenal hematoma and bleeding at the puncture site were recorded. The perirenal hematoma and gross hematuria were re-examined 24 hours after surgery.Results:Compared with the group A and the group B, the incidence of postoperative bleeding related complications in the group C was lower. The incidence of perirenal hematoma 24 hours after surgery in the group A was 62.09%, the group B was 62.50%, and the group C was 44.09%, with a statistically significant difference ( P=0.003); The incidence of gross hematuria 24 hours after surgery in the group A was 8.79%, the group B was 7.29%, and the group C was 1.57%, with a statistically significant difference ( P=0.030). The incidence of immediate postoperative perirenal hematoma in the group A was 52.20%, 53.12% in the group B, and 38.58% in the group C, with a statistically significant difference ( P=0.033). Conclusions:Immediate compression hemostasis for 5 minutes after ultrasound guided percutaneous renal biopsy can effectively reduce postoperative perirenal hematoma and gross hematuria, alleviate postoperative pain, shorten bed rest time, and improve surgical safety.
RESUMEN
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.
RESUMEN
Objective:To study the clinical characteristics and management strategies of late bleeding after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of 58 patients with post-pancreaticoduodenectomy hemorrhage (PPH) admitted to the Department of Hepatobiliary Surgery of the Second Hospital of Hebei Medical University from March 2018 to March 2022 were retrospectively analyzed, including 42 males and 16 females, aged (61.88±11.02) years old. According to the occurrence of intra-abdominal erosion factors (e.g., pancreatic fistula, biliary fistula, gastrointestinal anastomotic fistula, intra-abdominal abscess), patients were divided into the erosion group ( n=42) and non-erosion group ( n=16). All patients underwent standard lymphadenectomy. Clinical data including the PPH time-point, occurrence of rebleeding, and treatment outcomes were accessed. The management strategies of PPH in the two groups of patients were analyzed. Results:The PPH time-point in the erosion group and non-erosion patients was 8.00 (5.00, 19.25) d and 21.50 (12.75, 26.75) d, respectively ( P=0.001). PPH can occurred within one month after surgery in both erosion and non-erosion groups. In the erosion group, 31 cases (73.81%, 31/42) were treated by re-operation, two (4.76%, 2/42) by interventional radiology and nine (21.43%, 9/42) with conservative protocol, respectively. In the non-erosion group, five cases (31.25%, 5/16) were treated by re-operation, seven (43.75%, 7/16) by interventional radiology and four (25.00%, 4/16) with conservative protocol, respectively. The incidence of re-bleeding is higher in the erosion group [47.6% (20/42) vs 12.5% (2/16), P<0.05]. Clinical manifestations, sites and severity of bleeding, and treatment outcomes were also different in the erosion and non-erosion groups (all P<0.05). Conclusions:The occurrence of intra-abdominal erosion factors can affect the clinical characteristics and treatment strategy of late bleeding after laparoscopic pancreaticoduodenectomy. Surgery remains the treatment of choice for post-pancreaticoduodenectomy hemorrhage either as an urgent or last resort.
RESUMEN
AIM:To investigate the effects of subchronic aluminum exposure on the expression of silent infor-mation regulator(Sirt1),Kelch-like ECH-associated protein 1(Keap1),nuclear factor E2-related factor 2(Nrf2),and microRNA-128-3p(miR-128-3p)in the hippocampus of rats.Additionally,we aimed to explore the mechanism of miR-128-3p and the Sirt1-Keap1/Nrf2 signaling pathways in aluminum-induced cognitive impairment in rats.METHODS:Thirty-two healthy 6-week-old SPF male SD rats,weighing(190±20)g,were randomly divided into four groups based on body weight:control group,low-dose(10 μmol/kg)group,medium-dose(20 μmol/kg)group,and high-dose(40 μmol/kg)group,with 8 rats in each group.The rat exposure model was established by intraperitoneal injection of maltol alumi-num.The Morris water maze test was used to assess the learning and memory ability of the rats.Western blot analysis was performed to measure the protein expression of Sirt1,Keap1 and Nrf2 in the hippocampus,while RT-qPCR was used to measure the expression of miR-128-3p in the hippocampus.The level of reactive oxygen species(ROS)in the cerebral cor-tex was detected using fluorescence staining in frozen sections.RESULTS:(1)In the positioning cruise experiment,the escape latency of the aluminum exposure group was significantly higher than that of the control group on the 3rd,4th,and 5th days(P＜0.05).On day 6,the number of times the rats crossed the platform and the platform quadrant in the high-dose group was reduced compared to the control and low-dose groups(P＜0.01).(2)The expression levels of Sirt1 and Nrf2 in the hippocampal tissues of all groups decreased gradually with increasing maltol aluminum exposure dose.The ex-pression level of Keap1 increased gradually with increasing maltol aluminum exposure dose.The expression level of miR-128-3p in the high-dose group was significantly higher than that in the control group(P＜0.05).(3)The content of gluta-thione peroxidase in the hippocampus of rats decreased with increasing exposure dose,while ROS levels gradually in-creased.CONCLUSION:Subchronic aluminum exposure can increase the expression of miR-128-3p in the rat hippo-campus and suppress the Sirt1-Keap1/Nrf2 signaling pathway.This inhibition prevents the activation of the Sirt1-Keap1/Nrf2 signaling pathway,leading to a reduced antioxidant capacity.The imbalance in the antioxidant system in rats results in oxidative damage to nerve cells and a subsequent decline in cognitive function.

The median survival time of 188 patients was 22 months, and the postoperative 1-, 2- and 3-year survival rate was 90.9%, 43.1% and 18.7%, respectively. Conclusion:LRHCCA is safe and feasible, with satisfactory short-term effect, under the coditions of clinicians with rich experience in laparoscopic surgery and patients with strict surgical evaluation.
RESUMEN
Objective:To investigate the application value of three dimensional (3D) imaging fusion navigation system (hereinafter referred as navigation system) in laparoscopic pan-creatic surgery.Methods:The retrospective and descriptive study was conducted. The clinical data of two volunteers, including volunteer 1 undergoing laparoscopic pancreaticoduodenectomy for cholangiocarcinoma and volunteer 2 undergoing laparoscopic pancreaticotomy + splenectomy for pancreatic cancer, who were admitted to the Second Hospital of Hebei Medical University from December 2020 to May 2021 were collected. The 2 volunteers were females, aged 68 years and 40 years, respectively. The self-developed navigation system was applied in laparoscopic simulator model test, including in rigid-body model and prosthesis model, and clinical test. Observation indicators: (1) results of model test; (2) results of clinical test. Measurement data with normal distribution were represented as Mean± SD. Results:(1) Results of model test. The rigid-body model or prosthesis model with occlusion can be seen in the laparoscopic visual field of the initial laparoscopic simulator. The rigid-body model or prosthesis model with occlusion and rigid-body model or prosthesis model without occlusion can be seen in the 3D visual reconstruction image of enhanced computer tomography (CT) examination. The rigid-body model or prosthesis model with occlusion can be seen in the laparoscopic visual field of the initial laparoscopic simulator after the 3D visual reconstruction image was superimposed and fused with the real-time laparoscopic image. Both of the rigid-body model and prosthesis model were in high consistency, with the distance error of marker points were (0.26±0.11)mm and (0.29±0.18)mm, respectively. (2) Results of clinical test. The abdominal organs and blood vessels with occlusion of the 2 volunteers can be seen in the initial laparoscopic visual field. The location of tumor, important organs and blood vessels can be seen in the navigation system using the 3D visual reconstruction image of enhanced CT examination. The location of tumor, important organs and important blood vessels can be seen in the laparoscopic visual field after the 3D visual reconstruction image was superimposed and fused with the real-time laparoscopic image. The distance error of marker points of the volunteer 1 was (1.36±0.57)mm and the distance error of marker points of the volunteer 2 was (1.24±0.33)mm.Conclusions:The self-developed navigation system can integrate the preoperative 3D visual reconstruction image of enhanced CT examination and the intraoperative real-time laparoscopic image with a good effect. The relationship between deep tissue and blood vessels which is not clarified in conventional laparoscopy can be shown in the navigation system assisted laparoscopic pancreatic surgery.
RESUMEN
Objective:To compare and analyze the perioperative outcomes of jaundiced patients undergoing laparoscopic pancreaticoduodenectomy (LPD) using preoperative percutaneous transhepatic cholangial drainage (PTCD) versus endoscopic nasobiliary drainage (ENBD).Methods:The perioperative data of 173 patients who underwent LPD at the Second Hospital of Hebei Medical University from January 2016 to December 2020 and were treated preoperatively with either PTCD versus ENBD to alleviate jaundiced were retrospectively analyzed. There were 100 males and 73 females, with age of (60.4±10.8) years old. These patients were divided into the PTCD group ( n=126) and the ENBD group ( n=47). Clinical data including operation time, blood loss, transfusion volume, R 0 resection, and postoperative complications were compared. Results:There was no convension to open surgery. There were no significant differences in operation time, blood loss, transfusion volume, R 0 resection rate, pathological results and hospital stay between the two groups ( P>0.05). For the PTCD group, the pancreatic fistula rate was 10.3% (13/126) and the post-operative hemorrhage rate was 8.7% (11/126). They were both significantly lower than those of the ENBD group [25.5% (12/47) and 25.5% (12/47) respectively, P<0.05]. There were also significant differences in the postoperative complications according to the Clavien-Dindo classification system between the two groups ( P=0.008). Conclusion:Compared with ENBD, PTCD had the advantages of lower post-operative pancreatic fistula and post-operative hemorrhage rates, resulting in a better postoperative recovery.
RESUMEN
Pancreaticoduodenectomy was invented by Codivila in 1898. It was not widely applied because of the difficulties in organ removal and digestive tract reconstruction, high risks of postoperative complications and mortality. The undesired outcomes of operation and the patients seeking treatment urge the medical technicians to keep improving the operation. Nowadays, this surgery has become a routine procedure for the therapeutic option of tumors in the head and periampullary area of the pancreas, with significant improvements in short and long-term outcomes. This paper reviewed the development of pancreaticoduodenectomy and discusseed its application in the future.
RESUMEN
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.
