Efficacy of Laparoscopic Cholecystectomy in Treating Patients with Gallstones and Its Effect on Interleukin-6 and Tumor Necrosis Factor-α Levels

Objective:To investigate the efficacy of laparoscopic cholecystectomy in the treatment of patients with gallstones and its effect on the levels of interleukin-6(IL-6)and tumor necrosis factor-α(TNF-a).Methods:A total of 82 patients with gallstones admitted from July 2020 to July 2023 were recruited and allocated into control and observation groups using the random number table method,with 41 cases in each group.The patients were treated with laparoscopic cholecystectomy,with the anterior triangle anatomical approach to the gallbladder in the control group and the posterior triangle anatomical approach to the gallbladder in the observation group.The treatment effect and inflammatory factor levels of both groups were observed and compared.Results:When comparing the clinical outcomes of both patient groups,the key parameters evaluated included time to mobilization,duration of surgery,extubation time,and intraoperative bleeding.The observation group exhibited a significant advantage in these parameters compared to the control group(P<0.05).Regarding the levels of inflammatory factors between the two groups before and after treatment,there was no significant difference in values before treatment.However,following treatment,patients in the observation group showed significantly lower levels of IL-6,TNF-α,and C-reactive protein(CRP)compared to the control group(P<0.05).Conclusion:Patients undergoing laparoscopic cholecystectomy for gallstones can benefit from the implementation of the posterior triangular anatomical approach to the gallbladder,which not only enhances therapeutic efficacy but also offers significant advantages in reducing levels of IL-6,TNF-α,and CRP.Therefore,it is recommended for the widespread adoption of this treatment approach in clinical practice.

A new abdominal drainage tube fixation method for 3-port laparoscopic cholecystectomy improves patients’postoperative quality of life

Objective Laparoscopic surgery has become a routine general surgery with many advantages,such as alleviating abdominal pain.However,postoperative pain caused by abdominal drainage tubes has attracted little attention from medical staff.The aim of this study was to explore the influence of a new abdominal drainage tube fixation method for 3-port laparoscopic cholecystectomy(LC)on patients’postoperative quality of life.Methods Patients who underwent 3-port LC with abdominal drainage tubes in the Department of Hepatobiliary Surgery of Linyi People’s Hospital from March 1,2023 to October 31,2023 due to gallstones with chronic cholecystitis were selected for this study.The patients were randomly divided into an experimental group and a control group.In the experimental group,the new abdominal drainage tube fixation method was used,while in the control group,the traditional method was used.Afterward,the quality of life of patient in terms of pain,activity,recovery time,and mental health status was evaluated.The exudate around the patient’s drainage tube was collected for bacterial culture and analysis.Results A total of 139 patients were randomly divided into an experimental group(70 patients)and a control group(69 patients).The patients’baseline characteristics were not significantly different.The patients in the experimental group had better outcomes in quality of life,with higher pain scores(24.03±2.37 vs.15.48±2.29,p<0.001)and activity scores(20.57±1.78 vs.14.13±1.43,p<0.001),and a shorter postoperative recovery time(2.36±0.68 d vs.2.96±1.34 d,p<0.001).The same results were shown in linear regression analysis scores of the 2 groups.The positive rate of bacterial culture in the exudate around the patient’s drainage tube in the experimental group was significantly lower than that in the control group(12.9%vs.43.5%,p<0.001);and furthermore,the positive rate of conditional pathogenic bacteria was even lower(7.1%vs.33.3%,p<0.001)in the experimental group than in the control group.Conclusion This new abdominal drainage tube fixation method can effectively promote patient rehabilitation and improve the quality of life for patient following 3-port LC with abdominal drainage tubes.

Clinical efficacy of laparoscopic cholecystectomy plus cholangioscopy for the treatment of cholecystolithiasis combined with choledocholithiasis

BACKGROUND Currently,endoscopic retrograde cholangiopancreatography(ERCP)plus laparoscopic cholecystectomy(LC)is the main treatment for cholecystolithiasis combined with choledocholithiasis.However,the treatment is unsatisfactory,and the development of better therapies is needed.AIM To determine the clinical efficacy of LC plus cholangioscopy for cholecystolithiasis combined with choledocholithiasis.METHODS Patients(n=243)with cholecystolithiasis and choledocholithiasis admitted to The Affiliated Haixia Hospital of Huaqiao University(910th Hospital of Joint Logistic Support Force)between January 2019 and December 2023 were included in the study;111 patients(control group)underwent ERCP+LC and 132 patients(observation group)underwent LC+laparoscopic common bile duct exploration(LCBDE).Surgical success rates,residual stone rates,complications(pancreatitis,hyperamylasemia,biliary tract infection,and bile leakage),surgical indicators[intraoperative blood loss(IBL)and operation time(OT)],recovery indices(postoperative exhaust/defecation time and hospital stay),and serum inflammatory markers[C-reactive protein(CRP)],tumor necrosis factor-α(TNF-α),and interleukin-6(IL-6)were compared.RESULTS No significant differences in surgical success rates and residual stone rates were detected between the observation and control groups.However,the complication rate,IBL,OT,postoperative exhaust/defecation time,and hospital stays were significantly reduced in the observation group compared with the control group.Furthermore,CRP,TNF-α,and IL-6 Levels after treatment were reduced in the observation group compared with the levels in the control group.CONCLUSION These results indicate that LC+LCBDE is safer than ERCP+LC for the treatment of cholecystolithiasis combined with choledocholithiasis.The surgical risks and postoperative complications were lower in the observation group compared with the control group.Thus,patients may recover quickly with less inflammation after LCBDE.

Evaluating effectiveness and safety of combined percutaneous transhepatic gallbladder drainage and laparoscopic cholecystectomy in acute cholecystitis patients:Meta-analysis

BACKGROUND Acute cholecystitis(AC)is a common disease in general surgery.Laparoscopic cholecystectomy(LC)is widely recognized as the"gold standard"surgical procedure for treating AC.For low-risk patients without complications,LC is the recommended treatment plan,but there is still controversy regarding the treatment strategy for moderate AC patients,which relies more on the surgeon's experience and the medical platform of the visiting unit.Percutaneous transhepatic gallbladder puncture drainage(PTGBD)can effectively alleviate gallbladder inflammation,reduce gallbladder wall edema and adhesion around the gallbladder,and create a"time window"for elective surgery.AIM To compare the clinical efficacy and safety of LC or PTGBD combined with LC for treating AC patients,providing a theoretical basis for choosing reasonable surgical methods for AC patients.METHODS In this study,we conducted a clinical investigation regarding the combined use of PTGBD tubes for the treatment of gastric cancer patients with AC.We performed searches in the following databases:PubMed,Web of Science,EMBASE,Cochrane Library,China National Knowledge Infrastructure,and Wanfang Database.The search encompassed literature published from the inception of these databases to the present.Subsequently,relevant data were extracted,and a meta-analysis was conducted using RevMan 5.3 software.RESULTS A comprehensive analysis was conducted,encompassing 24 studies involving a total of 2564 patients.These patients were categorized into two groups:1371 in the LC group and 1193 in the PTGBD+LC group.The outcomes of the meta-analysis revealed noteworthy disparities between the PTGBD+LC group and the LC group in multiple dimensions:(1)Operative time:Mean difference(MD)=17.51,95%CI:9.53-25.49,P<0.01;(2)Conversion to open surgery rate:Odds ratio(OR)=2.95,95%CI:1.90-4.58,P<0.01;(3)Intraoperative bleeding loss:MD=32.27,95%CI:23.03-41.50,P<0.01;(4)Postoperative hospital stay:MD=1.44,95%CI:0.14-2.73,P=0.03;(5)Overall postoperative compli-cation rate:OR=1.88,95%CI:1.45-2.43,P<0.01;(6)Bile duct injury:OR=2.17,95%CI:1.30-3.64,P=0.003;(7)Intra-abdominal hemorrhage:OR=2.45,95%CI:1.06-5.64,P=0.004;and(8)Wound infection:OR=0.These find-ings consistently favored the PTGBD+LC group over the LC group.There were no significant differences in the total duration of hospitalization[MD=-1.85,95%CI:-4.86-1.16,P=0.23]or bile leakage[OR=1.33,95%CI:0.81-2.18,P=0.26]between the two groups.CONCLUSION The combination of PTGBD tubes with LC for AC treatment demonstrated superior clinical efficacy and enhanced safety,suggesting its broader application value in clinical practice.

Research on the prognostic value of adjusting intraperitoneal threedimensional quality evaluation mode in laparoscopic cholecystectomy patients

BACKGROUND Benign gallbladder diseases have become a high-prevalence condition not only in China but also worldwide.The main types of benign gallbladder diseases include gallbladder polyps,acute and chronic cholecystitis,and gallstones,with gallstones being the most common,accounting for over 70%of cases.Although the mortality rate of benign gallbladder diseases is low,they carry obvious potential risks.Studies have shown that an increased incidence of benign gallbladder diseases can increase the risk of cardiovascular diseases and gallbladder cancer,resulting in a substantial disease burden on patients and their families.AIM To assess the medical utility of the Configuration-Procedure-Consequence(CPC)three-dimensional quality evaluation model in modulating the prognosis of laparoscopic cholecystectomy patients.METHODS A total of 98 patients who underwent laparoscopic cholecystectomy in our hospital from February 2020 to January 2022 were selected as the subjects.According to the random number table method,they were divided into a study group and a control group,with 49 patients in each group.The control group received routine perioperative care,while the study group had the addition of the CPC three-dimensional quality evaluation.The postoperative recovery-related indicators(time to first flatus,time to oral intake,time to ambulation,hospital stay),stress indicators(cortisol and adrenaline levels),distinctions in anxiety and RESULTS The time to first flatus,time to oral intake,time to ambulation,and hospital stay of the study group patients were obviously lower than those of the control group patients,with statistical significance(P<0.05).On the 1st day after admission,there were no obvious distinctions in cortisol and adrenaline levels in blood samples,as well as in the Self-Rating Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)scores between the study group and the control group(P>0.05).However,on the 3rd day after surgery,the cortisol and adrenaline levels,as well as SAS and SDS scores of the study group patients,were obviously lower than those of the control group patients(P<0.05).The study group had 2 cases of incisional infection and 1 case of pulmonary infection,with a total incidence of complications of 6.12%(3/49),which was obviously lower than the 20.41%(10/49)in the control group(P<0.05).CONCLUSION Implementing the CPC three-dimensional quality evaluation model for patients undergoing laparoscopic cholecystectomy can help accelerate their perioperative recovery process,alleviate perioperative stress symptoms,mitigate anxiety,depression,and other adverse emotions,and to some extent,reduce the incidence of perioperative complications.

Clinical efficacy of laparoscopic cholecystectomy combined with endoscopic papillary balloon dilation in treatment of gallbladder stones with common bile duct stones: A retrospective study

BACKGROUND The incidence of cholelithiasis has been on the rise in recent years,but the choice of procedure is controversial.AIM To investigate the efficacy of laparoscopic cholecystectomy(LC)combined with endoscopic papillary balloon dilation(EPBD)in patients with gallbladder stones(GS)with common bile duct stones(CBDS).METHODS The clinical data of 102 patients with GS combined with CBDS were selected for retrospective analysis and divided into either an LC+EPBD group(n=50)or an LC+endoscopic sphincterotomy(EST)group(n=52)according to surgical methods.Surgery-related indexes,postoperative recovery,postoperative complications,and expression levels of inflammatory response indexes were compared between the two groups.RESULTS Total surgical time,stone free rate,rate of conversion to laparotomy,and successful stone extraction rate did not differ significantly between the LC+EPBD group and LC+EST group.Intraoperative hemorrhage,time to ambulation,and length of hospitalization in the LC+EPBD group were lower than those of the LC+EST group(P<0.05).The rate of total complications of the two groups was 9.80%and 17.65%,respectively,and the difference was not statistically significant.No serious complications occurred in either group.At 48 h postoperatively,the expression levels of interleukin-6,tumor necrosis factor-α,high-sensitivity Creactive protein,and procalcitonin were lower in the LC+EPBD group than in the LC+EST group(P<0.05).At 3 d postoperatively,the expression levels of aspartate transaminase,alanine transaminase,and total bilirubin were lower in the LC+EPBD group than in the LC+EST group(P<0.05).CONCLUSION LC combined with EPBD and LC combined with EST are both effective procedures for the treatment of GS with CBDS,in which LC combined with EPBD is beneficial to shorten the patient’s hospitalization time,reduce the magnitude of elevated inflammatory response indexes,and promote postoperative recovery.

A Case Report and Literature Review: A Case of Delayed Bile Leakage Following Laparoscopic Cholecystectomy

Background: Delayed bile leakage after laparoscopic cholecystectomy, defined as occurring more than 72 hours after surgery, is a rare and serious complication of laparoscopic cholecystectomy, with an incidence rate of 0.060%. Case Declaration: This case report details a patient diagnosed with delayed bile leakage 43 days after laparoscopic cholecystectomy. The patient was discharged from our hospital after undergoing CT-guided puncture treatment, with no obvious complications identified. The patient was monitored for one year following the procedure, during which time no significant discomfort was reported. Objective: This case report is to analyse and review the clinical manifestations, diagnosis, treatment and prevention of delayed bile leakage after cholecystectomy, with reference to the relevant literature. Results: Delayed bile leakage after laparoscopic cholecystectomy can be prevented, although not eliminated. It is recommended that the operator treat the operation with caution, avoid taking risks, and adhere to careful procedures and strict separation according to the requirements. This approach is key to preventing late bile leakage in the postoperative period.

Analysis of the Effect of Laparoscopic Versus Open Cholecystectomy in Patients with Cholelithiasis and the Effect on CRP and IL-1βLevels

Objective:To evaluate the therapeutic effect of laparoscopic cholecystectomy(LC)and open cholecystectomy(OC)on cholelithiasis.Methods:92 cases of cholelithiasis patients admitted to the hospital in the past 2 years were selected and grouped by random number table;the observation group was treated with LC;the reference group was treated with OC,and the inflammatory factor and other indexes were compared.Results:The total effective rate of the observation group was higher than that of the reference group,and the perioperative indexes were better than that of the reference group(P<0.05).Preoperatively,the C-reactive protein(CRP)and interleukin-1β(IL-1β)levels and immune function indexes of the two groups were compared,and no difference was seen(P>0.05).At 5 days postoperatively,the CRP and IL-1βlevels of the observation group were lower than those of the reference group,and the immune function indicators were higher than those of the reference group(P<0.05).The complication rate of the observation group was lower than that of the reference group(P<0.05).Conclusion:LC can increase the effective rate of cholelithiasis patients,improve their perioperative indexes,reduce the inflammatory response,protect patients’immune function,and ensure higher surgical safety.

Early versus delayed laparoscopic cholecystectomy in uncomplicated biliary colic: An observational study

Objective:Biliary colic is a condition treated with laparoscopic cholecystectomy.However,the outcomes of surgery depend on early or delayed time points.Few research findings reported no benefits of early over delayed,on contra,other reported benefits.This study aims to compare the benefits associated with early and delayed laparoscopic cholecystectomy among uncomplicated biliary colic patients.Methods:This observational study included patients with right upper abdominal pain and abdominal ultrasound showing cholelithiasis.Patients who were admitted at the first and second visits(within 6 weeks of the first visit)were assigned to the early and delayed groups,respectively.All participants were followed up for one-week postsurgery.The diagnosis of the patient,postoperative hospital stay,duration of surgery and complications were noted and compared primarily.Results:A total of 80 patients were included,40 each in the early group and delayed group.The patients in the two groups had comparable mean ages(40.55±13.12 y vs.40.45±12.06 y,p=0.972).The early group had more female patients(72.5%vs.45.0%,p=0.012).The duration of hospital stay(2.18±0.38 d vs.2.68±1.04 d,p=0.009)and duration of surgery(61.63±3.64 min vs.71.13±16.19 min,p=0.001)were found to be significantly different between the early and delayed groups.Only 1(2.5%)patient in both groups was converted to open cholecystectomy.Recurrent biliary colic requiring hospital admission was seen in 1(2.5%)patient and 6(15.0%)patients,acute cholecystitis in 2(5.0%)and 6(15.0%),biliary pancreatitis in 1(2.5%)and 2(5.0%),and obstructive jaundice in 1(2.5%)and 1(2.5%)in the early and delayed groups,respectively,with insignificant differences(p>0.05).Conclusion:Early laparoscopic cholecystectomy decreases the operating time and duration of hospital stay.In terms of postoperative complications,our study did not find any significant difference between the groups.

Vascular injury during laparoscopic cholecystectomy:An oftenoverlooked complication

Laparoscopic cholecystectomy is one of the most frequently performed procedures in gastrointestinal surgery worldwide.Bleeding complications due to vascular injuries represent an important cause of morbidity and mortality,especially when facing major bleeding during laparoscopy,where bleeding control can be technically challenging in inexperienced hands.Interestingly,the reported incidence rate of conversion to open surgery due to vascular lesions is approximately 0%-1.9%,with a mortality rate of approximately 0.02%.The primary aim of this article was to perform an up-to-date overview regarding the incidence and surgical management of vascular injuries during laparoscopic cholecystectomy according to the available scientific evidence.

Spilled gallstones mimicking a retroperitoneal sarcoma following laparoscopic cholecystectomy

Laparoscopic cholecystectomy has become a standard treatment of symptomatic gallstone disease. Although spilled gallstones are considered harmless, unretrieved gallstones can result in intra-abdominal abscess. We report a case of abscess formation due to spilled gallstones after laparoscopic cholecystectomy mimicking a retroperitoneal sarcoma on radiologic imaging. A 59-year-old male with a surgical history of a laparoscopic cholecystectomy complicated by gallstones spillage presented with a 1 mo history of constant right-sided abdominal pain and tenderness. Computed tomography and magnetic resonance imaging demonstrated a retroperitoneal sarcoma at the sub-hepatic space. On open exploration a 5 cm × 5 cm retroperitoneal mass was excised. The mass contained purulent material and gallstones. Final pathology revealed abscess formation and foreign body granuloma. Vigilance concerning the possibility of lost gallstones during laparoscopic cholecystectomy is important. If possible, every spilled gallstone during surgery should be retrieved to prevent this rare complication.

Utility of routine blood tests after elective laparoscopic cholecystectomy for symptomatic gallstones

AIM To evaluate the value of blood testing after elective laparoscopic cholecystectomy and its association with procedure related complications.METHODS Charts of all patients undergoing elective laparoscopic cholecystectomy from January 2013 through December2014 were reviewed retrospectively for demographics,indication for surgery,operative course and outcome.In our institution the decision to perform postoperative blood analysis is left for the discretion of the surgeon,therefore we had the possibility to compare the results of those who had blood analyses results to those who did not.Analysis was performed to identify variables associated with the decision to perform postoperative blood tests.Subsequently a univariate and multivariate analyses was performed comparing the two cohorts.Secondary subgroup analysis was performed to identify factors associated with procedure related complications.RESULTS Five hundred and thirty-two elective laparoscopic cholecystectomies for symptomatic gallstones were performed during the study period.Sixty-four percent of the patients(n=340)had blood tests taken post operatively.Patients that had laboratory tests taken were older(P=0.006,OR=1.01),had longer surgery(P<0.001,OR=3.22)had more drains placed(P<0.001,OR=3.2)and stayed longer in the hospital(P<0.001,OR=1.2).A subgroup analysis of the patients who experienced complications revealed longer stay in the hospital(P<0.001),higher body mass index(BMI)(P=0.04,OR=1.08),increased rates of drain placement(P=0.006,OR=3.1)and higher conversion rates(P=0.01,OR=14.6).Postoperative blood tests withdrawals were not associated with complications(P=0.44).On Multivariate analysis BMI and drain placement were independently associated with complications.CONCLUSION The current study indicate that routine postoperative blood tests after elective laparoscopic cholecystectomy for symptomatic gallstones does not predict complications and may have an added benefit in diagnosis and management of cases were the surgeon encountered true technical difficulty during surgery.

Awake laparoscopic cholecystectomy:A case report and review of literature

BACKGROUND Laparoscopic cholecystectomy(LC)is one of the most widely practiced surgical procedures in abdominal surgery.Patients undergo LC during general anaesthesia;however,in recent years,several studies have suggested the ability to perform LC in patients who are awake.We report a case of awake LC and a literature review.CASE SUMMARY A 69-year-old patient with severe pulmonary disease affected by cholelithiasis was scheduled for LC under regional anaesthesia.We first performed peridural anaesthesia at the T8-T9 level and then spinal anaesthesia at the T12-L1 level.The procedure was managed in total comfort for both the patient and the surgeon.The intra-abdominal pressure was 8 mmHg.The patient remained stable throughout the procedure,and the postoperative course was uneventful.CONCLUSION Evidence has warranted the safe use of spinal and epidural anaesthesia,with minimal side effects easily managed with medications.Regional anaesthesia in selected patients may provide some advantages over general anaesthesia,such as no airway manipulation,maintenance of spontaneous breathing,effective postoperative analgesia,less nausea and vomiting,and early recovery.However,this technique for LC is not widely used in Europe;this is the first case reported in Italy in the literature.Regional anaesthesia is feasible and safe in performing some types of laparoscopic procedures.Further studies should be carried out to introduce this type of anaesthesia in routine clinical practice.

Explore the clinical nursing path of daytime laparoscopic cholecystectomy under the guidance of enhanced recovery after surgery

Objective:To explore the safety and effectiveness nursing of 12 h discharged daytime laparoscopic cholecystectomy guided by enhanced recovery after surgery(ERAS)concept.Methods:Included 180 cases from the 12 h discharged daytime laparoscopic cholecystectomy patients which assessmended and guided by ERAS,with the 180 case of routine cholecystectomy patients as control group at the same time.To quantitatively analyze the related indexes of perioperative period and ERAS concept,and evaluate the clinical safety,and effectiveness.Results:It displayed no significant differences in average age,gender distribution,duration of gallbladder related disease and distribution of clinical symptoms between the two groups(P>0.05).There were also no significant differences in preoperative smoking history,hypertension history,cardio-cerebrovascular history,abdominal operation history and disease composition ratio between the two groups(P>0.05).None of the patients had conversion to laparotomy.Compared with the conventional surgery group,there were no significant differences in the average amount of intraoperative blood loss,operation time and muscle strength before returning to the ward in patients with ERAS guided day surgery(P>0.05).When compared with the conventional surgery group,ERAS guided day surgery group had no significant difference in muscle strength between the two groups when going under the ground(t=1.64,P=0.082).Also,the level of peripheral white blood cells in patients with ERAS guided day surgery group was not significantly increased at 6 h after surgery.Meanwhile,liver function related indexes,transaminase,total bilirubin,indirect bilirubin were not significantly abnormal(P>0.05).Conclusion:12 h daytime laparoscopic cholecystectomy guided by ERAS concept can improve the clinical efficacy of patients with cholecystolithiasis,which is safe and feasible.

Laparoscopic management of remnant gall bladder with stones: Lessons from a tertiary care centre's experience

Objective:Laparoscopic cholecystectomy is currently the gold standard for treating symptomatic gallstone disease.Despite its success,approximately 10%of patients may experience persistent biliary symptoms,leading to the post-cholecystectomy syndrome.A remnant gallbladder with cystic duct or bile duct stones is one of the causes of this syndrome.The objective of this study was to shed light on the clinical manifestations,evaluation,therapeutic strategies,and outcomes associated with laparoscopic management of symptomatic remnant gallbladders.Methods:This was a retrospective study,conducted over a five-year period(January 2017 to December 2022)at Apollo Hospitals in South India.All patients who underwent laparoscopic completion cholecystectomy for a remnant gall bladder were included.The following data were collected:patient demographics,symptoms,preoperative investigations,intraoperative details and post operative outcomes.Results:In total,36 patients were included and analysed.The majority of patients were male(25,69.4%),with a mean age of 50.7±12.1 years.The most common presentation was pain in the upper abdomen or right upper quadrant region(24,66.7%).The laparoscopic approach was attempted in all patients,with a success rate of 94.4%.Two patients required conversion to open surgery.Cholecystoenteric fistula to the colon was observed in one patient.Choledocholithiasis was observed in 7 patients(19.4%),and stone clearance was successfully achieved using endoscopic retrograde cholangiopancreatography in all patients preoperatively.Conclusion:Incomplete gall bladder removal either intentionally or unintentionally leaves a remnant gall bladder that is at risk for stone formation and infection.Patients who have this clinical entity with symptoms require a redo or complete cholecystectomy,a complex procedure associated with certain risks.This study highlights the feasibility and safety of laparoscopic completion cholecystectomy for the management of remnant gallbladder with cystic duct or bile duct stones.

Hem-o-lok clip migration to duodenal bulb post-cholecystectomy:A case report

BACKGROUND Hem-o-lok clips are typically used to control the cystic duct and vessels during laparoscopic cholecystectomy(LC)and common bile duct exploration for stones in the bile duct and gallbladder.Here,we report a unique example of Hem-o-lok clip movement towards the duodenal bulb after LC,appearing as a submucosal tumor(SMT).Additionally,we provide initial evidence of gradual and evolving endoscopic manifestations of Hem-o-lok clip migration to the duodenal bulb wall and review the available literature.CASE SUMMARY A 72-year-old man underwent LC for gallstones,and Hem-o-lok clips were used to ligate both the cystic duct and cystic artery.Esophagogastroduodenoscopy(EGD)2 years later revealed an SMT-like lesion in the duodenal bulb.Due to the symptomatology,the clinical examination did not reveal any major abnormalities,and the patient was followed up as an outpatient.A repeat EGD performed 5 months later revealed an SMT-like lesion in the duodenal bulb with raised edges and a central depression.A third EGD was conducted,during which a Hem-o-lok clip was discovered connected to the front side of the duodenum.The clip was extracted easily using biopsy forceps,and no complications occurred.Two months after the fourth EGD,the scar was surrounded by normal mucosa.CONCLUSION Clinicians should be aware of potential post-LC complications.Hem-o-lok clips should be removed if symptomatic.

Near-infrared cholangiography with intragallbladder indocyanine green injection in minimally invasive cholecystectomy

Laparoscopic cholecystectomy(LC)remains one of the most commonly performed procedures in adult and paediatric populations.Despite the advances made in intraoperative biliary anatomy recognition,iatrogenic bile duct injuries during LC represent a fatal complication and consist an economic burden for healthcare systems.A series of methods have been proposed to prevent bile duct injury,among them the use of indocyanine green(ICG)fluorescence.The most commonly reported method of ICG injection is the intravenous administration,while literature is lacking studies investigating the direct intragallbladder ICG injection.This narrative mini-review aims to assess the potential applications,usefulness,and limitations of intragallbladder ICG fluorescence in LC.Authors screened the available international literature to identify the reports of intragallbladder ICG fluorescence imaging in minimally invasive cholecystectomy,as well as special issues regarding its use.Literature search retrieved four prospective cohort studies,three case-control studies,and one case report.In the three case-control studies selected,intragallbladder near-infrared cholangiography(NIRC)was compared with standard LC under white light,with intravenous administration of ICG for NIRC and with standard intraoperative cholangiography(IOC).In total,133 patients reported in the literature have been administered intragallbladder ICG administration for biliary mapping during LC.Literature includes several reports of intragallbladder ICG administration,but a standardized technique has not been established yet.Published data suggest that NIRC with intragallbladder ICG injection is a promising method to achieve biliary mapping,overwhelming limitations of IOC including intervention and radiation exposure,as well as the high hepatic parenchyma signal and time interval needed in intravenous ICG fluorescence.Evidence-based guidelines on the role of intragallbladder ICG fluorescence in LC require the assessment of further studies and multicenter data collection into large registries.

Paediatric gallstones and laparoscopic cholecystectomy

Introduction: Gall stones disease is a rare oc-currence in paediatric patients and the diagno-sis is often overlooked. Patients often present with non-specific symptoms of abdominal pain and the classic features of gallstones are some-times absent [1]. The aim of our study is to in-crease the awareness of cholecystitis and acute pancreatitis being a possible occurrence in the paediatric age group and should therefore be in the differential diagnosis of acute abdominal pain in children. We undertook a retrospective analy- sis of all the paediatric patients recorded as hav- ing had a laparoscopic Cholecystectomy per-formed at Prince Charles Hospital. 8 paediatric patients underwent Laparoscopic cholecysteco- my between 2000 and 2008 consisting of 5 fe-male patients and 3 male patients. The average age of the cohort was 14.1 years [12-16]. Pre- morbid obesity was a feature in 4 patients and all patients reported high fat diet. Abdominal Ul- trasound used to assess all 8 patients who pre- sented with acute abdomen showed gallstones to be present in all. 7 patients underwent an ele- ctive procedure 3-6 months after the initial di-agnosis was made and 1 patient had laparosco- pic Cholecystectomy within 72 hours of initial presentation. 1 patient was found to have an in- herited haematological disorder and 2 of the pa- tients were sisters with a family history of gall- stone disease. 2 patients presented with acute pancreatitis. Gallstone related cholecystitis is a rare occurrence amongst paediatric patients and is often overlooked as a differential diagnosis. We report 8 patients over an 8 year period. Con- clusion: It is important that clinicians include cholecystitis and biliary colic in the differential diagnosis of patients presenting with acute ab-domen in childhood not explained by other di-agnoses. Laparoscopic Cholecystectomy is the treatment of choice and has minimal complica-tions.

Single-incision laparoscopic cholecystectomy:Single institution experience and literature review

Single-incision laparoscopic surgery is a rapidly evolving field as a bridge between traditional laparoscopic surgery and natural orifice transluminal endoscopic surgery.We report one of the initial clinical experiences in Japan with this new technique.Four cases of gallbladder diseases were selected for this new technique.A single curved intra-umbilical 25-mm incision was made by pulling out the umbilicus.A 12-mm trocar was placed through an open approach,and the abdominal cavity was explored with a 10-mm semiflexible laparoscope.Two 5-mm ports were inserted laterally from the laparoscope port.A 2-mm mini-loop retractor was inserted to retract the fundus of the gallbladder.Dissection was performed using an electric cautery hook and an Endograsper roticulator.There were two women and two men with a mean age of 50.5 years(range:40-61 years).All procedures were completed successfully without any perioperative complications.In all cases,there was no need to extend the skin incision.Average operative time was 88.8 min.Postoperative follow-up didnot reveal any umbili-cal wound complication.Single-incision laparoscopic cholecystectomy is feasible and a promising alternative method as scarless abdominal surgery for the treatment of some patients with gallbladder disease.

Single-incision vs three-port laparoscopic cholecystectomy:Prospective randomized study

AIM:To compare the clinical outcome of single-inci-sion laparoscopic cholecystectomy(SILC)with threeport laparoscopic cholecystectomy(TPLC). METHODS:Between 2009 and 2011,one hundred and two patients with symptomatic benign gallbladder diseases were randomized to SILC(n=49)or TPLC (n=53).The primary end point was post operative pain score(at 6 h and 7 d).Secondary end points were blood loss,operation duration,overall complications,postoperative analgesic requirements,length of hospital stay,cosmetic result and total cost.Surgical techniques were standardized and all operations were performed by one experienced surgeon,who had performed more than 500 laparoscopic cholecystectomies. RESULTS:One patient in the SILC group required conversion to two-port LC.There were no open conversions or major complications in either treatment groups.There were no differences in terms of esti-mated blood loss(mean±SD,14±6.0 mL vs 15±4.0 mL),operation duration(mean±SD,41.8±17.0 min vs 38.5±22.0 min),port-site complications(contusion at incision:5 cases vs 4 cases and hematoma at inci- sion:2 cases vs 1 case),total cost(mean±SD,12 075 ±1047 RMB vs 11 982±1153 RMB)and hospital stay (mean±SD,1.0±0.5 d vs 1.0±0.2 d),respectively. TPLC had a significantly worse visual analogue pain score at 8 h after surgery(mean±SD,3.5±1.6 vs 2.0 ±1.5),however,the scores were similar on day 7(mean ±SD,2.5±1.4 vs 2.0±1.3).Cosmetic satisfaction, as determined by a survey at 2 mo follow-up favored SILC(mean±SD,8±0.4 vs 6±0.2). CONCLUSION:SILC is a safe and feasible approach in selected patients.The main advantages are a better cosmetic result and less pain.
