The role of virtual reality simulation training in laparoscopic skills training for young physicians / 中华医学教育探索杂志

Objective:To explore the significance of laparoscopic virtual reality simulation training by analyzing the learning curve of laparoscopic cholecystectomy among young general surgeons who had participated in laparoscopic skills training at our hospital.Methods:Fifty young surgeons were divided into two groups, with the intervention group participating in virtual reality simulation training and the control group participating in traditional laparoscopic clinical training. After completion of the training, 30 laparoscopic cholecystectomies were performed under the supervision of highly qualified surgeons with extensive laparoscopic experience. CUSUM analysis was applied to plot the trainees' surgical learning curve based on the completion rate, surgical score and operative time. " x" is the number of surgical cases and " k" is the slope. The value of x when k=0 was calculated and the surgical learning curves and intraoperative scores of the 2 groups of trainees were compared. SPSS 23.00 was performed for t-test and Chi-square test. Results:The intervention and control groups crossed the surgical learning curve at x=19.24±0.39 and x=21.72±0.73 respectively, with significant differences ( P<0.01); the intervention and control groups scored (10.82±2.73) and (9.71±2.69) for gallbladder exposure ( t=4.61, P<0.01), (12.59±3.12) and (8.87±2.99) for gallbladder dissection triangle ( t=6.21, P<0.01), and (10.69±3.38) and (8.80±3.55) for gallbladder dissection ( t=3.10, P<0.01). Conclusions:Virtual reality simulation training can facilitate the translation of basic laparoscopic training skills into clinical skills and can promote the growth of young general surgeons.

Effect of acetaminophen combined with ketorolac tromethamine on analgesia after laparoscopic chol-ecystectomy / 临床麻醉学杂志

Objective To investigate the effectiveness and safety of acetaminophen combined with ketorolac tromethamine in pain management early after laparoscopic cholecystectomy(LC).Methods Ninety patients with LC under general anesthesia,42 males and 48 females,aged 18-78 years,BMI 18-28 kg/m2,ASA physical statusⅠorⅡ,were selected and randomly divided into two groups by random num-ber table method:the acetaminophen combined with ketorolac tromethamine group(group AK)and the nal-buphine group(group NA),45 patients in each group.Group AK received 500 mg(diluted to 50 ml)of acetaminophen injection and 30 mg of ketorolac tromethamine(diluted to 10 ml)injection pumped 15 mi-nutes before induction of anesthesia,and group NA received 50 ml of NS injection and 0.2 mg/kg of nalbu-phine(diluted to 10 ml)injection pumped at the same time.Postoperative pain was recorded 0.5,3,6,12,and 24 hours after surgery using VAS pain scores(the non-inferiority boundary Δ = 1.0 score).The sleep quality score on the night of surgery,the number of remedial analgesia cases within 24 hours after sur-gery,the Ramsay sedation score 0.5,3,and 6 hours after surgery,the occurrence of adverse reactions such as nausea and vomiting within 24 hours after surgery,and the overall satisfaction of patients were recorded.Results Compared with group NA,the VAS pain scores 0.5 hour after surgery was reduced in group AK(P＜0.05).The sleep quality score and overall satisfaction in group AK were significantly higher than those in group NA(P＜0.05).There were no significant differences in the rate of remedial analgesia,the score of Ramsay sedation at different time points and the incidence of nausea and vomiting within 24 hours after surgery between the two groups.Conclusion Acetaminophen combined with ketorolac tromethamine is not less effective than nalbuphine in relieving early postoperative pain after laparoscopic cholecystectomy without increasing the incidence of nausea and vomiting.Patients receiving acetaminophen combined with ketorolac tromethamine have higher sleep quality scores on the night of surgery and overall satisfaction.

Effect of right stellate ganglion block on shoulder pain after laparoscopic cholecystectomy / 临床麻醉学杂志

Objective To investigate the effect of right stellate ganglion block(SGB)on postoper-ative shoulder pain in patients receiving laparoscopic cholecystectomy(LC).Methods A total of 104 pa-tients scheduled for LC from April to August 2022,32 males and 72 females,aged 18-64 years,ASA phys-ical status Ⅰ orⅡ,were selected and randomized into two groups:the stellate ganglion block group(group S,n = 51)and the control group(group C,n = 53).Immediately after intubation,0.2%ropivacaine 4 ml was used for ultrasound-guided right SGB in group S,and saline 4 ml was injected at the same site in group C.The number of cases of post-laparoscopic shoulder pain(PLSP)and the duration of PLSP were re-corded within 48 hours after operation.The VAS pain scores of PLSP were recorded to assess the level of PLSP immediately after operation(T1),2 hours after operation(T2),6 hours after operation(T3),12 hours after operation(T4),24 hours after operation(T5),and 48 hours after operation(T6).The number of effective compressions of the PCIA pump and the salvage analgesia were recorded.The adverse reactions such as nausea,vomiting,and abdominal distension were recorded.Results The incidence of PLSP and the rate of patients with PLSP lasting more than 10 hours in group S was significantly lower than those in group C(P＜0.05),and the degree of PLSP in group S was significantly lower than that in group C at T3-T5(P＜0.05).The number of effective compressions of the PCIA pump and the salvage analgesia rate in group S was significantly lower than those in group C(P＜0.05).The incidence of nausea in group S was significantly lower than that in group C(P＜0.05).Conclusion Right stellate ganglion block can reduce the incidence of PLSP in patients receiving LC,relieve the pain degree of PLSP,and reduce the incidence of adverse reactions.

A novel comparison of erector spinae plane block and paravertebral block in laparoscopic cholecystectomy

SUMMARY OBJECTIVE: Erector spinae plane block is an updated method than paravertebral block, possessing a lower risk of complications. This study aimed to compare erector spinae plane and paravertebral blocks to safely reach the most efficacious analgesia procedure in laparoscopic cholecystectomy cases. METHODS: The study included 90 cases, aged 18-70 years, classified as American Society of Anesthesiologists I-II, who underwent an laparoscopic cholecystectomy procedure. They were randomly separated into three groups, namely, Control, erector spinae plane, and paravertebral block. No block procedure was applied to Control, and a patient-controlled analgesia device was prepared containing tramadol at a 10 mg bolus dose and a 10-min locked period. The pain scores were recorded with a visual analog scale for 24 h postoperatively. RESULTS: The visual analog scale values at 1, 5, 10, 20, and 60 min at rest and 60 min coughing were found to be significantly higher in Control than in paravertebral block. A significant difference was revealed between Control vs. paravertebral block and paravertebral block vs. erector spinae plane in terms of total tramadol consumption (p=0.006). Total tramadol consumption in the first postoperative 24 h was significantly reduced in the paravertebral block compared with the Control and erector spinae plane groups. CONCLUSION: Sonography-guided-paravertebral block provides sufficient postoperative analgesia in laparoscopic cholecystectomy surgery. Erector spinae plane seems to attenuate total tramadol consumption.

Modified thoracoabdominal nerves block through perichondrial approach for laparoscopic cholecystectomy

SUMMARY OBJECTIVE: A new block, namely, modified thoracoabdominal nerves block through perichondrial approach, is administered below the costal cartilage. We sought to compare the analgesic efficacy of the modified thoracoabdominal nerves block through perichondrial approach block with local anesthetic infiltration at the port sites in an adult population who underwent laparoscopic cholecystectomy. METHODS: Patients who will undergo laparoscopic cholecystectomy were randomized to receive bilateral ultrasound-guided modified thoracoabdominal nerves block through perichondrial approach blocks or local anesthetic infiltration at the port insertion sites. The primary outcome was the total amount of tramadol used in the first 12 h postoperatively. The secondary outcomes were total IV tramadol consumption for the first postoperative 24 h and visual analog scale scores. RESULTS: The modified thoracoabdominal nerves block through perichondrial approach group had significantly less tramadol use in the first 12 h postoperatively (p<0.001). The modified thoracoabdominal nerves block through perichondrial approach group's visual analog scale scores at rest (static) and with movement (dynamic) were significantly lower compared with the port infiltration group (p<0.05). CONCLUSION: Patients who received modified thoracoabdominal nerves block through perichondrial approach block had significantly less analgesic consumption and better pain scores than those who received port-site injections after laparoscopic cholecystectomy.

Abstract: Introduction: having an effective analgesia in the postoperative period is essential to avoid complications associated with pain in patients undergoing laparoscopic cholecystectomy. Objectives: test the effectiveness of intravenous lidocaine for postoperative pain in cholecystectomized patients by laparoscopy. Material and methods: an experimental, randomized, single-blind study was carried out in patients who underwent laparoscopic cholecystectomy at the No. 1 Regional General Hospital in Obregon, Sonora. They were divided into two groups randomly: group L to whom we applied lidocaine 1.5 mg/k in infusion and group P to whom placebo was applied. A statistical analysis was performed in SPSS v. 22 and a p < 0.05 was considered significant. Results: adequate pain management was observed in patients of group L upon admission to PACU (p = 0.002), lower consumption of transoperative fentanyl without statistical difference against placebo (p = 0.086), lower use of post-surgical rescue analgesia (p = 0.045), but higher incidence of adverse effects such as hypotension and bradycardia (p = 0.024). Conclusions: the infusion of lidocaine is effective for the management of immediate postsurgical pain; as well it decreases opioid consumption and analgesic rescue dose, with a low incidence of nausea and vomiting, but associated with hypotension after surgery.

The effects of positive end-expiratory pressure (PEEP) application on optic nerve sheath diameter in patients undergoing laparoscopic cholecystectomy: a randomized trial

Abstract Background: Positive end-expiratory pressure (PEEP) can overcome respiratory changes that occur during pneumoperitoneum application in laparoscopic procedures, but it can also increase intracranial pressure. We investigated PEEP vs. no PEEP application on ultrasound measurement of optic nerve sheath diameter (indirect measure of increased intracranial pressure) in laparoscopic cholecystectomy. Methods: Eighty ASA I-II patients aged between 18 and 60 years scheduled for elective laparoscopic cholecystectomy were included. The study was registered in the Australian New Zealand Clinical Trials (ACTRN12618000771257). Patients were randomly divided into either Group C (control, PEEP not applied), or Group P (PEEP applied at 10 cmH20). Optic nerve sheath diameter, hemodynamic, and respiratory parameters were recorded at six different time points. Ocular ultrasonography was used to measure optic nerve sheath diameter. Results: Peak pressure (PPeak) values were significantly higher in Group P after application of PEEP (p = 0.012). Mean respiratory rate was higher in Group C at all time points after application of pneumoperitoneum (p < 0.05). The mean values of optic nerve sheath diameters measured at all time points were similar between the groups (p > 0.05). The pulmonary dynamic compliance value was significantly higher in group P as long as PEEP was applied (p = 0.001). Conclusions: During laparoscopic cholecystectomy, application of 10 cmH2O PEEP did not induce a significant change in optic nerve sheath diameter (indirect indicator of intracranial pressure) compared to no PEEP application. It would appear that PEEP can be used safely to correct

Introducción: El situs inversus totalis es una condición congénita en la cual los órganos torácicos y abdominales se encuentran en posición contraria a la posición habitual. En la literatura quirúrgica internacional se encuentran publicados no más de 55 casos de colecistectomía en pacientes con situs inversus totalis. La resolución laparoscópica de una paciente en nuestra Institución nos permite revisar esta particular condición patológica. Caso Clínico: Paciente femenino de 43 años de edad hospitalizada por una colecistitis aguda la cual es resuelta por vía laparoscópica sin incidentes. Material y Método: Se resume la literatura actual mediante una extensa revisión en PubMed de los reportes más relevantes. Considerando que todos los artículos publicados son casos clínicos o pequeñas series de casos, se presentan los resultados de esta revisión en tablas con estadística descriptiva básica. Discusión: Se discuten las características generales de estos pacientes, la presentación clínica, diagnóstico y técnica quirúrgica. Conclusión: La colecistectomía laparoscópica constituye el estándar de oro en pacientes con situs inversus y patología biliar, la cual debe ser realizada por un cirujano experimentado acomodando los trocares apropiadamente, debido a las dificultades técnicas que se encuentran en estos pacientes por las anomalías anatómicas propias de esta condición. El diagnóstico radiológico actual permite la planificación del abordaje y del procedimiento quirúrgico apropiado para cada paciente.

Introduction: Situs inversus totalis is a congenital condition in which the thoracic and abdominal organs are in the opposite position from normal anatomy. We found no more than 55 cases of cholecystectomy in patients with situs inversus totalis published in the international surgical literature. The laparoscopic resolution of a patient in our Institution allows us to review this particular pathological condition. Clinical Case: A 43-year-old female patient was admitted for acute cholecystitis and was resolved laparoscopically without any incidents. Material and Method: We summarized the current literature through an extensive PubMed review of the most relevant reports. Considering that all published articles are clinical cases or small case series, we present the results of this review in a table with basic descriptive statistics. Discussion: We discuss the general characteristics of these patients, clinical presentation, diagnosis, and surgical technique. Conclusions: Laparoscopic cholecystectomy is the gold standard in patients with situs inversus and biliary pathology, which must be performed by an experienced surgeon, properly accommodating the trocars due to the technical difficulties in these patients secondary to anatomical anomalies typical of this condition. Current radiological diagnosis allows planning the appropriate approach and surgical procedure for each patient.

Outcome of Laparoscopic Cholecystectomy in a District Level Hospital

Background: Laparoscopic cholecystectomy is a type of surgery that uses smaller incision than open cholecystectomy. LC has been performed as outpatient procedure for many years. Few studies have been conducted with primary focus on patient acceptance and preferences in terms of safety and satisfaction. We tried to explore its feasibility in otherwise healthy individuals undergoing laparoscopic cholecystectomy. The aim of the study of laparoscopic cholecystectomy is significantly affected by acute cholecystitis. Mechanical, biochemical, and bacteriological factors which are believed to participate in this inflammatory process are responsible for the different pathological processes observed in acute cholecystitis and in symptomatic cholelithiasis. Material & Methods: Data from 57 patients between the age group 20 to 70 years with cholelithiasis who underwent laparoscopic cholecystectomy in a private Hospital, Madaripur, Bangladesh from April 2018 to June 2020 as ambulatory surgery (hospital stay 23 Hours) with or without overnight stay were analyzed. Complications, admissions and readmissions, patient satisfaction and treatment expenditure were assessed. Results: There were 48 (84.2%) female and 9 (15.8%) male with a median age of 42 years. Only 2.4% patients required readmission while 9.2% patients had unplanned admission. 76.4% percent patients were highly satisfied with the procedure. Treatment cost was about 15% lower than routine inpatient operation. Conclusion: Laparoscopic cholecystectomy is safe and feasible. LC can be performed as an outpatient procedure with a low rate of complications and admissions/readmissions. Patient acceptance in terms of satisfaction is high.

Bilateral versus unilateral erector spinae plane block for postoperative analgesia in laparoscopic cholecystectomy: a randomized controlled study

Abstract Introduction Laparoscopic cholecystectomy (LC) is the common surgical intervention for benign biliary diseases. Postoperative pain after LC remains as an important problem, with two components: somatic and visceral. Trocar entry incisions lead to somatic pain, while peritoneal distension with diaphragm irritation leads to visceral pain. Following its description by Forero et al., the erector spinae plane (ESP) block acquired considerable popularity among clinicians. This led to the use of ESP block for postoperative pain management for various operations. Materials and methods This study was conducted between January and June 2019. Patients aged between 18 and 65 years with an American Society of Anesthesiologists (ASA) physical status I-II, scheduled for elective laparoscopic cholecystectomy were included in the study. All the patients received bilateral or unilateral ESP block at the T8 level preoperatively according to their groups. Results There was no significant difference between the groups in terms NRS scores either at rest or while coughing at any time interval except for postoperative 6th hour (p = 0.023). Morphine consumption was similar between the groups but was significantly lower in group B at 12 and 24 hours (p = 0.044 and p = 0.022, respectively). Twelve patients in group A and three patients in group B had shoulder pain and this difference was statistically significant (p = 0.011). Discussion In conclusion, bilateral ESP block provided more effective analgesia than unilateral ESP block in patients undergoing elective LC. Bilateral ESP block reduced the amount of opioid consumption and the incidence of postoperative shoulder pain.

Effect analysis of PDCA cycle on prophylactic use of antibiotics in laparoscopic cholecystectomy during perioperative period / 中国药房

OBJECTIVE To evaluate the effect of PDCA cycle on prophylactic use of antibiotics in laparoscopic cholecystectomy during perioperative period and to conduct pharmacoeconomic analysis. METHODS Using retrospective analysis method， 80 discharged patients of each group underwent laparoscopic cholecystectomy were randomly selected from Hefei Second People’s Hospital before PDCA cycle （from May to June 2019）， after the first round of PDCA cycle （from May to June 2020）， after the second round of PDCA cycle （from May to June 2021） according to real or basic reasons for irrational drug use. The rationality of prophylactic use of antibiotics for patients was evaluated. The general situation， antibiotic use， clinical efficacy and treatment cost of patients were compared before cycle and after the first and second rounds of PDCA cycle. Cost-effectiveness analysis method and sensitivity analysis method were adopted to evaluate pharmacoeconomic significance of PDCA cycle. RESULTS After two rounds of PDCA cycle， the irrational rate of antibiotics， cost ratio of antibiotics， the number of days of antibiotics use， DDDs， drug utilization index， the frequency of antibiotics use per capita， the total amount of antibiotics， the cost of antibiotics， the total amount of drugs， and the total cost of hospitalization all decreased significantly （P＜0.05）. The results of cost-effectiveness analysis indicated that the pharmacoeconomic effect was the best after two rounds of PDCA cycle； the results of sensitivity analysis were consistent with it， which confirmed the reliability of the research results. CONCLUSIONS PDCA CPA- cycle promotes the rational use of antibiotics of laparoscopic cholecystectomy during perioperative period， reduces the cost of antibiotics and relieves the economic burden of patients.

Effects of midazolam combined with propofol on recovery of patients with laparoscopic cholecystectomy / 药学实践与服务

Objective To explore the effect midazolam combination with propofol on postoperative recovery in patients undergoing laparoscopic cholecystectomy. Methods A total of 162 patients who were admitted to the hospital for laparoscopic cholecystectomy from April 2019 to January 2021 were selected. According to different anesthesia methods, they were divided into control group (midazolam anesthesia) and observation group (midazolam combined with propofol anesthesia), with 81 cases in each group. The stress index levels before and after operation, MoCA scores before operation (T0), 24 h after operation (T1) and 48 h after operation (T2), sleep quality at T0, the first day after operation (T3) and the second day after operation (T4), the perioperative recovery were compared between the two groups. Results The levels of Cor and NE, the recovery time of eyes opening, extubation, orientation, and the incidence of adverse reactions in the observation group were lower than those in the control group (P<0.05). Observation group MMSE score when T1, T2, T3, T4 sleep quality score were higher than control group (P<0.05). Conclusion Midazolam combined with propofol was safe and had good postoperative recovery in patients undergoing laparoscopic cholecystectomy.

Objective:To investigate the feasibility and potential of fluorescent cholecystic bile duct visualization with direct intravenous injection of indocyanine green(ICG) in obese patients undergoing laparoscopic cholecystectomy(LC).Methods:The clinical data of 132 patients with LC combined with obesity admitted to the Department of Hepatobiliary and Pancreatic Surgery of the Second People′s Hospital of Changzhou City, affiliated to Nanjing Medical University, from January 2023 to July 2023 were retrospectively analyzed. They were divided into fluorescence group( n=65) and control group( n=67) according to whether indocyanine green fluorescence navigation was used or not. There were 50 males and 82 females, and all the enrolled patients body mass index≥28 kg/m 2. Two groups identify the time of the three tubes, intraoperative bleeding, operation time, postoperative hospitalization time, white blood cell count(WBC), C-reactive protein(CRP), alanine aminotransferase(ALT), gamma-glutamyl transferase(GGT), and postoperative follow-up in the fluorescent and control groups were counted respectively. Measurement data with skewed distribution were expressed as M( Q1, Q3), and intergroup comparisons were performed using the Mann-Whitney U test; counting data were described by frequency(rate), and intergroup comparisons were made by applying the chi-square test, Fisher′s exact probability method, and chi-square corrected test according to the difference in the minimum frequency. Results:Surgery was successfully completed in both groups. Preoperative inflammatory indicators and liver function levels were also not statistically significant( P>0.05). The time to identify the three tubes, operation time, intraoperative bleeding, and postoperative hospitalization in the fluorescence group were 18.00(13.50, 20.00) min, 40.00(30.00, 50.00) min, 5.00(5.00, 10.00) mL, and 2.00(1.50, 3.00) d, and in the control group were 32.00(25.00, 45.00) min, 65.00(50.00, 85.00) min, 41.00(41.00, 46.00) mL, and 4.00(3.00, 5.00) d. The differences between the two groups were statistically significant( P<0.05). The postoperative leukocyte count, postoperative CRP, and postoperative GGT were 9.15(7.10, 11.75)×10 9/L, 7.19(3.22, 20.00) mg/L, and 34.0(20.0, 49.0) U/L in the fluorescence group, and 13.05(11.02, 15.59)×10 9/L, and 18.78(12.90, 32.95) mg/L in the control group, respectively, 82.5(68.5, 114.5) U/L, and the differences between the two groups were statistically significant ( P<0.05). None of the patients showed abdominal pain, abnormal liver function and hepatobiliary ultrasound in the follow-up findings within 2 months after surgery. Conclusion:The effect of obesity, a factor that interferes with ICG fluorescence, is extremely limited, and ICG fluorescence cholangiography is a useful technique in the obese population that not only improves the efficiency of the procedure, but also increases intraoperative safety, with results superior to those of conventional laparoscopic cholecystectomy.

Comparing one-step common bile duct exploration plus cholecystectomy with two-step endoscopic sphincterotomy plus cholecystectomy in patients over 80 years with concomitant gallbladder and common bile duct stones / 中华肝胆外科杂志

Objective:To compare safety and efficacy of one-stage laparoscopic common bile duct exploration plus laparoscopic cholecystectomy (LCBDE+ LC) with endoscopic retrodrade cholangiopancreatography plus laparoscopic cholecystectomy (ERCP+ LC) in elderly patients with concomitant gallbladder and common bile duct (CBD) stones.Methods:This is a two-center retrospective study with clinical data on 492 patients aged over 80 years diagnosed with concomitant gallbladder and CBD stones treated between January, 2014 and December, 2020 at The First Affiliated Hospital of Wenzhou Medical University and Quzhou Hospital Affiliated to Wenzhou Medical University. There were 254 males and 238 females, aged (83.9±3.0) years. These patients were divided into two groups based on their operative methods: the one-stage group (LCBDE+ LC, n=186) and the two-stage group (ERCP+ LC, n=306). Differences in surgery, stones and hospitalization costs were compared between the two groups. Results:When compared with the ERCP+ LC group, the LCBDE+ LC group had significantly higher incidences of previous gastrectomy [21.5%(40/186) vs 4.2%(13/306)], multiple stones [77.4%(144/186) vs 49.3%(151/306)], larger stone diameter [13.7(6.4, 18.6)mm vs 10.9(5.7, 16.1) mm], and increased hospitalization expenditure [(2.37±0.31) Wanyuan vs (3.26±0.44) Wanyuan] (all P<0.05). However, the rates of residual stone [2.7%(5/186) vs 1.3%(4/306)], stone recurrence [2.2%(4/186) vs 5.2%(16/306)], postoperatively overall complications [3.2%(6/186) vs 1.3%(4/306)], and total hospital stay [(10.7±6.2) d vs (11.3±5.4) d] were not significantly different between the two groups (all P>0.05). Conclusions:Allowing for the similar safety and effectiveness, and lower hospitalization expenditure, LCBDE+ LC was a preferred choice for patients aged over 80 year, especially in patients who had previous gastrectomy, multiple large CBD stones, or who could not accept endoscopic procedures for treatment of CBD stones.

Research advances in the diagnosis and treatment of benign gallbladder disease / 中华肝胆外科杂志

Benign gallbladder diseases are common in general surgery practice, and laparoscopic cholecystectomy (LC) has become the standard treatment for these conditions. With the widespread adoption of LC and the improved understanding of gallbladder disease, it is necessary to re-evaluate the diagnosis and treatment of benign gallbladder disease. Based on the latest expert consensus on the diagnosis and treatment of benign gallbladder disease, this review aims to provide an overview of the diagnostic and treatment strategies for benign gallbladder diseases. Specifically, it focuses on enhancing our understanding of the role of benign gallbladder diseases in the development of gallbladder cancer, the impact of congenital biliary anomalies on the diagnostic and treatment processes of benign gallbladder diseases, and the significance of the preoperative examinations.

Clinical disputes between sphincter of Oddi function and biliary system diseases / 中华消化外科杂志

The link between sphincter of Oddi function with biliary system (gallbladder and bile duct) diseases is considered to be very complicated. Whether routine prophylactic laparos-copic cholecystectomy should be carried out after endoscopic sphincterotomy to remove bile duct stones has been controversial worldwide. Actually, this is a very common and important clinical question which needs to be answered. The author spends a lot of time and efforts to broadly read and analyze on published articles related to this topic, and tries, from the aspects of the anatomy and function of sphincter of Oddi, the biliary diseases causing by dysfunction or discordance of sphincter of Oddi, and the impacting of artificial destruction of sphincter of Oddi on the gallbladder and bile duct of patients, to come up with an answer to this question based on scientific and medical evidence.
