BACKGROUND An intrauterine device(IUD)is a contraceptive device placed in the uterine cavity and is a common contraceptive method for Chinese women.However,an IUD may cause complications due to placement time,intrauterine pressure and other factors.Ectopic IUDs are among the most serious complications.Ectopic IUDs are common in the myometrium and periuterine organs,and there are few reports of ectopic IUDs in the urinary bladder,especially in the anterior wall.CASE SUMMARY A 52-year-old woman was hospitalized due to a urinary bladder foreign body found via abdominal ultrasound and computed tomography(CT)examination.The patient had a 2-year history of recurrent abdominal distension and lower abdominal pain,accompanied by frequent urination,urgency,dysuria and other discomfort.Ultrasound examination revealed foreign bodies in the bladder cavity,with calculus on the surface of the foreign bodies.CT revealed a circular foreign body on the anterior wall of the urinary bladder,suggesting the possibility of an ectopic IUD.After laparoscopic exploration,an annular IUD was found in the anterior wall of urinary bladder,and an oval calculus with a diameter of approximately 2 cm was attached to the surface of the bladder cavity.The IUD and calculus were successfully and completely removed.The patient recovered well after surgery.CONCLUSION Abdominal ultrasound and CT are effective methods for detecting ectopic IUDs.The IUD is located in the urinary bladder and requires early surgical treatment.The choice of surgical method is determined by comprehensively considering the depth of the IUD in the bladder muscle layer,the situation of complicated calculus,the situation of intravesical inflammation and medical technology and equipment. 展开更多

In laparoscopic surgery, the surgeons are equipped with the suitable tools for the surgery, while the laparoscope is used to capture the operation environment and displays it on a monitor. This paper presents the mathematical kinematic position modeling of the laparoscopic tools used for autonomous positioning of a laparoscope in such operations. These models are obtained using Denavit-Hartenberg (D-H) Notations and Homogenous Transformation Matrix (HTM). The laparoscopic tools are considered as six degrees of freedom (DOF) mechanisms while the laparoscope has four DOF. The 3D loop closure equation is used to obtain the laparoscope kinematic position models in terms of those of the laparoscopic tools. These models are used to simulate and align the laparoscope camera with the surgeon’s laparoscopic Tools Center Points (TCP). The obtained results show the smooth positioning of the laparoscope camera for better visu-alization of laparoscopic surgery environments. 展开更多

BACKGROUND The incidence of gastric cancer has significantly increased in recent years.Surgical resection is the main treatment,but the method of digestive tract reconstruction after gastric cancer surgery remains controversial.In the current study,we sought to explore a reasonable method of digestive tract reconstruction and improve the quality of life and nutritional status of patients after surgery.To this end,we statistically analyzed the clinical results of patients with gastric cancer who underwent jejunal interposition double-tract reconstruction(DTR)and esophageal jejunum Roux-en-Y reconstruction(RY).AIM To explore the application effect of DTR in total laparoscopic radical total gastrectomy(TLTG)and evaluate its safety and efficacy.METHODS We collected the relevant data of 77 patients who underwent TLTG at the Fourth Hospital of Hebei Medical University from October 2021 to January 2023.Among them,35 cases were treated with DTR,and the remaining 42 cases were treated with traditional RY.After 1:1 propensity score matching,the cases were grouped into 31 cases per group,with evenly distributed data.The clinical characteristics and short-and long-term clinical outcomes of the two groups were statistically analyzed.RESULTS The two groups showed no significant differences in basic data,intraoperative blood loss,number of lymph node dissections,first defecation time after operation,postoperative hospital stay,postoperative complications,and laboratory examination results on the 1st,3rd,and 5th days after operation.The operation time of the DTR group was longer than that of the RY group[(307.58±65.14)min vs(272.45±62.09)min,P=0.016],but the first intake of liquid food in the DTR group was shorter than that in the RY group[(4.45±1.18)d vs(6.0±5.18)d,P=0.028].The incidence of reflux heartburn(Visick grade)and postoperative gallbladder disease in the DTR group was lower than that in the RY group(P=0.033 and P=0.038).Although there was no significant difference in body weight,hemoglobin,prealbumin,and albumin between the two groups at 1,3 and 6 months after surgery,the diet of patients in the DTR group was better than that in the RY group(P=0.031).CONCLUSION The clinical effect of DTR in TLTG is better than that of RY,indicating that it is a more valuable digestive tract reconstruction method in laparoscopic gastric cancer surgery. 展开更多

BACKGROUND Advancements in laparoscopic technology and a deeper understanding of intra-hepatic anatomy have led to the establishment of more precise laparoscopic hepatectomy(LH)techniques.The indocyanine green(ICG)fluorescence navi-gation technique has emerged as the most effective method for identifying hepatic regions,potentially overcoming the limitations of LH.While laparoscopic left hemihepatectomy(LLH)is a standardized procedure,there is a need for innova-tive strategies to enhance its outcomes.important anatomical markers,surgical skills,and ICG staining methods.METHODS Thirty-seven patients who underwent ICG fluorescence-guided LLH at Qujing Second People's Hospital between January 2019 and February 2022 were retrospectively analyzed.The cranial-dorsal approach was performed which involves dissecting the left hepatic vein cephalad,isolating the Arantius ligament,exposing the middle hepatic vein,and dissecting the parenchyma from the dorsal to the foot in order to complete the anatomical LLH.The surgical methods,as well as intra-and post-surgical data,were recorded and analyzed.Our hospital’s Medical Ethics Committee approved this study(Ethical review:2022-019-01).RESULTS Intraoperative blood loss during LLH was 335.68±99.869 mL and the rates of transfusion and conversion to laparotomy were 13.5%and 0%,respectively.The overall incidence of complications throughout the follow-up(median of 18 months;range 1-36 months)was 21.6%.No mortality or severe complications(level IV)were reported.CONCLUSION LLH has the potential to become a novel,standardized approach that can effectively,safely,and simply expose the middle hepatic vein and meet the requirements of precision surgery. 展开更多

BACKGROUND Although en bloc dissection of hepatic hilum lymph nodes has many advantages in radical tumor treatment,the feasibility and safety of this approach for laparo-scopic pancreaticoduodenectomy(LPD)require further clinical evaluation and investigation.AIM To explore the application value of the"five steps four quadrants"modularized en bloc dissection technique for accessing hepatic hilum lymph nodes in LPD patients.METHODS A total of 52 patients who underwent LPD via the"five steps four quadrants"modularized en bloc dissection technique for hepatic hilum lymph nodes from April 2021 to July 2023 in our department were analyzed retrospectively.The patients'body mass index(BMI),preoperative laboratory indices,intraoperative variables and postoperative complications were recorded.The relationships between preoperative data and intraoperative lymph node dissection time and blood loss were also analyzed.RESULTS Among the 52 patients,36 were males and 16 were females,and the average age was 62.2±11.0 years.There were 26 patients with pancreatic head cancer,16 patients with periampullary cancer,and 10 patients with distal bile duct cancer.The BMI was 22.3±3.3 kg/m²,and the median total bilirubin(TBIL)concentration was 57.7(16.0-155.7)µmol/L.All patients successfully underwent the"five steps four quadrants"modularized en bloc dissection technique without lymph node clearance-related complications such as postoperative bleeding or lymphatic leakage.Correlation analysis revealed significant associations between preoperative BMI(r=0.3581,P=0.0091),TBIL level(r=0.2988,P=0.0341),prothrombin time(r=0.3018,P=0.0297)and lymph node dissection time.Moreover,dissection time was significantly correlated with intraoperative blood loss(r=0.7744,P<0.0001).Further stratified analysis demonstrated that patients with a preoperative BMI≥21.9 kg/m²and a TIBL concentration≥57.7μmol/L had significantly longer lymph node dissection times(both P<0.05).CONCLUSION The"five steps four quadrants"modularized en bloc dissection technique for accessing the hepatic hilum lymph node is safe and feasible for LPD.This technique is expected to improve the efficiency of hepatic hilum lymph node dissection and shorten the learning curve;thus,it is worthy of further clinical promotion and application. 展开更多

BACKGROUND Laparoscopic radical gastrectomy is widely used,and perioperative complications have become a highly concerned issue.AIM To develop a predictive model for complications in laparoscopic radical gastrectomy for gastric cancer to better predict the likelihood of complications in gastric cancer patients within 30 days after surgery,guide perioperative treatment strategies for gastric cancer patients,and prevent serious complications.METHODS In total,998 patients who underwent laparoscopic radical gastrectomy for gastric cancer at 16 Chinese medical centers were included in the training group for the complication model,and 398 patients were included in the validation group.The clinicopathological data and 30-d postoperative complications of gastric cancer patients were collected.Three machine learning methods,lasso regression,random forest,and artificial neural networks,were used to construct postoperative complication prediction models for laparoscopic distal gastrectomy and laparoscopic total gastrectomy,and their prediction efficacy and accuracy were evaluated.RESULTS The constructed complication model,particularly the random forest model,could better predict serious complications in gastric cancer patients undergoing laparoscopic radical gastrectomy.It exhibited stable performance in external validation and is worthy of further promotion in more centers.CONCLUSION Using the risk factors identified in multicenter datasets,highly sensitive risk prediction models for complications following laparoscopic radical gastrectomy were established.We hope to facilitate the diagnosis and treatment of preoperative and postoperative decision-making by using these models. 展开更多

BACKGROUND Colorectal cancer is a common malignant tumor in China,and its incidence in the elderly is increasing annually.Inflammatory bowel disease is a group of chronic non-specific intestinal inflammatory diseases,including ulcerative colitis and Crohn’s disease.We included the clinicopathological and follow-up data of patients with colorectal cancer who underwent laparoscopic colectomy or open colectomy at our Gastrointestinal Department between January 2019 and December 2022.Surgical indicators,oncological indicators,and survival rates were compared between the groups.The results of 104 patients who met the above criteria were extracted from the database(laparoscopic colectomy group=63,open colectomy group=41),and there were no statistically significant differences in the baseline data or follow-up time between the two groups.RESULTS Intraoperative blood loss,time to first ambulation,and time to first fluid intake were significantly lower in the laparoscopic colectomy group than in the open colectomy group.The differences in overall mortality,tumor-related mortality,and recurrence rates between the two groups were not statistically significant,and survival analysis showed that the differences in the cumulative overall survival,tumor-related survival,and cumulative recurrence-free rates between the two groups were not statistically significant.CONCLUSION In elderly patients with colorectal cancer,laparoscopic colectomy has better short-term outcomes than open colectomy,and laparoscopic colectomy has superior long-term survival outcomes compared with open colectomy. 展开更多

BACKGROUND Colorectal surgeons are well aware that performing surgery for rectal cancer becomes more challenging in obese patients with narrow and deep pelvic cavities.Therefore,it is essential for colorectal surgeons to have a comprehensive understanding of pelvic structure prior to surgery and anticipate potential surgical difficulties.AIM To evaluate predictive parameters for technical challenges encountered during laparoscopic radical sphincter-preserving surgery for rectal cancer.METHODS We retrospectively gathered data from 162 consecutive patients who underwent laparoscopic radical sphincterpreserving surgery for rectal cancer.Three-dimensional reconstruction of pelvic bone and soft tissue parameters was conducted using computed tomography(CT)scans.Operative difficulty was categorized as either high or low,and multivariate logistic regression analysis was employed to identify predictors of operative difficulty,ultimately creating a nomogram.RESULTS Out of 162 patients,21(13.0%)were classified in the high surgical difficulty group,while 141(87.0%)were in the low surgical difficulty group.Multivariate logistic regression analysis showed that the surgical approach using laparoscopic intersphincteric dissection,intraoperative preventive ostomy,and the sacrococcygeal distance were independent risk factors for highly difficult laparoscopic radical sphincter-sparing surgery for rectal cancer(P<0.05).Conversely,the anterior-posterior diameter of pelvic inlet/sacrococcygeal distance was identified as a protective factor(P<0.05).A nomogram was subsequently constructed,demonstrating good predictive accuracy(C-index=0.834).CONCLUSION The surgical approach,intraoperative preventive ostomy,the sacrococcygeal distance,and the anterior-posterior diameter of pelvic inlet/sacrococcygeal distance could help to predict the difficulty of laparoscopic radical sphincter-preserving surgery. 展开更多

Background:Our clinical practice of laparoscopic liver resection(LLR)had achieved better short-term and long-term benefits for patients with hepatocellular carcinoma(HCC)over open liver resection(OLR),but the underlying mechanisms are not clear.This study was to find out whether systemic inflammation plays an important role.Methods:A total of 103 patients with early-stage HCC under liver resection were enrolled(LLR group,n=53;OLR group,n=50).The expression of 9 inflammatory cytokines in patients at preoperation,postoperative day 1(POD1)and POD7 was quantified by Luminex Multiplex assay.The relationships of the cytokines and the postoperative outcomes were compared between LLR and OLR.Results:Seven of the circulating cytokines were found to be significantly upregulated on POD1 after LLR or OLR compared to their preoperative levels.Compared to OLR,the POD1 levels of granulocytemacrophage colony-stimulating factor(GM-CSF),interleukin-6(IL-6),IL-8,and monocyte chemoattractant protein-1(MCP-1)in the LLR group were significantly lower.Higher POD1 levels of these cytokines were significantly correlated with longer operative time and higher volume of blood loss during operation.The levels of these cytokines were positively associated with postoperative liver injury,and the length of hospital stay.Importantly,a high level of IL-6 at POD1 was a risk factor for HCC recurrence and poor disease-free survival after liver resection.Conclusions:Significantly lower level of GM-CSF,IL-6,IL-8,and MCP-1 after liver resection represented a milder systemic inflammation which might be an important mechanism to offer better short-term and long-term outcomes in LLR over OLR. 展开更多

Surgery for lesions of the proximal part of the pancreatic body or neck can be challenging,and when enucleation is not possible,central pancreatectomy is an option.Laparoscopic central pancreatic resection is rarely described worldwide;it is considered a difficult procedure mainly because of the risk of double pancreatic fistula developing at two sites of resection.However,it seems to be an excellent alternative to distal pancreatectomy or pancreaticoduodenectomy,with the advantages of preserving functioning parenchyma and reducing endocrine and exocrine failure.Nevertheless,patients with pancreatic lesions requiring central resection are often managed with the open approach in many hospitals due to the complexity of total laparoscopic central pancreatectomy,which requires advanced laparoscopic skills,expertise and experience.Here,we report a case of a 29-year-old female who underwent total laparoscopic central pancreatic resection with gastro-pancreatic anastomosis for symptomatic serous cystadenoma.We discuss the details of case management and review the relevant literature. 展开更多

BACKGROUND Endometriosis is a chronic inflammatory condition affecting a significant proportion of women of reproductive age.Although laparoscopic surgery is commonly the preferred treatment,the decision to preserve or remove the ovaries remains controversial.Previous studies have yielded inconsistent results regarding the impact of ovarian preservation vs oophorectomy on fertility outcomes and disease recurrence.This prospective study aimed to address this knowledge gap by comparing the effects of these surgical approaches on spontaneous pregnancy rates,time to pregnancy,recurrence rates,and postoperative pain in patients with endometriosis.AIM To compare the reproductive outcomes and recurrence rates between ovarian preservation and oophorectomy in women undergoing laparoscopic surgery for endometriosis.METHODS This study was conducted at a tertiary care hospital between January 2019 and December 2023.A total of 312 women aged 18 to 40 years,diagnosed with endometriosis and undergoing laparoscopic surgery,were included.The patients were categorized into the ovarian preservation group(n=204)and the oophorectomy group(n=108).The primary outcome measure was the achievement of spontaneous pregnancy within 24 months post-surgery.Secondary outcomes included time to spontaneous pregnancy,recurrence rates,and postoperative pain scores.RESULTS The ovarian preservation group exhibited a significantly higher spontaneous pregnancy rate than that in the oophorectomy group(43.6%vs 28.7%,P=0.006).Moreover,the median time to spontaneous pregnancy was shorter in the ovarian preservation group(8.2 months vs 11.4 months,P=0.018).Nonetheless,endometriosis recurrence was more prevalent in the ovarian preservation group(22.1%vs 11.1%,P=0.014).The postoperative pain scores demonstrated similar improvements in both groups,with no significant differences observed.Subgroup analyses indicated that the benefit of ovarian preservation on spontaneous pregnancy rates was more evident among younger women(≤35 years)and those with advanced-stage endometriosis.CONCLUSION Ovarian preservation is associated with a high spontaneous pregnancy rate and a short time to pregnancy.However,because of the increased risk of recurrence,the decision should be based on age,fertility aspirations,and disease severity. 展开更多

Objective:Robotic-assisted surgery(RAS)is continuing to expand in use in surgical specialties,including foregut surgery.The available data on its use in large hiatal hernia(HH)repair are limited and conflicting.This study sought to determine whether there are significant differences in adverse outcomes following HH repair performed with a robotic approach vs.a laparoscopic approach.This study was limited to outcomes in patients with type II,III,and IV HHs,as these hernias are typically more challenging to repair.Methods:A retrospective analysis was performed from data obtained from TriNetX,a large deidentified clinical database,over a 10-year period.Adult patients who underwent type II,III,or IV HH repair were included in the study.HH with robotic repair was compared to laparoscopic repair.Cohorts were propensity score matched for demographic information and comorbidities.Risk ratios,risk differences(RDs)with 95%confidence intervals(CIs),and t test for each examined adverse outcome were used to estimate the effects of robotic repair vs.laparoscopic repair.Results:In total,20,016 patients who met the inclusion criteria were identified;1,515 patients utilized RAS,and 18,501 used laparoscopy.Prior to matching,there were significant differences in age,sex,comorbidity,and BMI between the two cohorts.After 1:1 propensity score matching,analyses of 1,514 well-matched patient pairs revealed no significant differences in demographics or comorbidities.Patients who underwent robotic repair were more likely to experience major complications,including venous thromboembolism(RD:0.007,95%CI:0.003,0.011;p?0.002),critical care(RD:0.023,95%CI:0.007,0.039;p?0.004),urinary/renal complications(RD:0.027,95%CI:0.014,0.041;p<0.001),and respiratory complications(RD:0.046,95%CI:0.028,0.064;p<0.001).RAS was associated with a significantly shorter length of stay(32.4±27.5 h vs.35.7±50.1 h,p?0.031),although this finding indicated a reduction in the length of stay of less than 4 hours.No statistically significant differences in risk of esophageal perforation,infection,postprocedural shock,bleeding,mortality,additional emergency room visits,cardiac complications,or wound disruption were found.Conclusions:Patients who undergo robotic-assisted large HH repair are at increased risk of venous thromboembolism,need critical care,urinary or renal complications and respiratory complications.Due to variations in RAS technique,experience,and surgical volumes,further study of this surgical approach and complication rates is warranted. 展开更多

This editorial is an analysis the review article by Nabi et al recently published in this journal.Achalasia Cardia is a disease whose pathophysiology is still unclear.It is known that there is inflammation of unknown aetiology leading to loss of ganglion cells in the muscularis propria.The end result is lower oesophageal sphincter spasm,loss of receptive relaxation,decreased oesophageal peristalsis,all leading on to varying degrees of dysphagia.The treatment of this condition is palliative in nature,performed by myotomy of the lower oesophagus either surgically or endoscopically.Gastroesophageal reflux disease(GERD)has been associated with the myotomy performed,particularly with the Peroral Endoscopic Myotomy(POEM)procedure.Nabi et al have provided an excellent overview of the latest developments in predicting,preventing,evaluating,and managing GERD subsequent to POEM.Based on this theme,this review article explores the concept of using histology of the oesophageal muscle layer,to grade the disease and thereby help tailoring the length/type of myotomy performed during the POEM procedure.In the future,will a histology based algorithm available preoperatively,help modify the POEM procedure,thereby decreasing the incidence of GERD associated with POEM? 展开更多

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. 展开更多

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. 展开更多
