Minimally invasive treatment of cholecysto-choledocal lithiasis:The point of view of the surgical endoscopist

The rate of choledocholithiasis in patients with symptomatic cholelithiasis is estimated to be approximately 10%-33%,depending on the patient's age.Development of Endoscopic Retrograde Cholangiopancreatography and Laparoscopic Surgery and improvement of diagnostic procedures have influenced new approaches to the management of common bile duct stones in association with gallstones.At present available minimally-invasive treatments of cholecysto-choledocal lithiasis include:single-stage laparoscopic treatment,perioperative endoscopic treatment and endoscopic treatment alone.Published data evidence that,associated endoscopic-laparoscopic approach necessitates increased number of procedures per patient while single-stage laparoscopic treatment is associated with a shorter hospital stay.However,current data does not suggest clear superiority of any one approach with regard to success,mortality,morbidity and cost-effectiveness.Considering the variety of therapeutic options available for management,a critical appraisal and decision-making is required.endoscopic retrograde cholangiopancreatography/EST should be adopted on a selective basis,i.e.,in patients with acute obstructive suppurative cholangitis,severe biliary pancreatitis,ampullary stone impaction or severe comorbidity.In a setting where all facilities are available,decision in the selection of the therapeutic option depends on the patients,the number and size of choledocholithiasis stones,the anatomy of the cystic duct and common bile duct,the surgical history of patients and local expertise.

Minimally invasive treatment of hepatic hemangioma by transcatheter arterial embolization combined with microwave ablation:A case report

BACKGROUND Hepatic hemangioma is the most common benign tumor of the liver.However,patients with large hemangiomas that cause compression symptoms or that are at risk of rupture may need further intervention.It is necessary to explore additional minimally invasive and personalized treatment options for hemangiomas.CASE SUMMARY A 47-year-old woman was diagnosed with a right hepatic hemangioma for more than 10 years.Abdominal contrast-enhanced computed tomography(CT)and contrast-enhanced ultrasound revealed that there was a large hemangioma in the right liver,with a size of approximately 95 mm×97 mm×117 mm.Due to the patient's refusal of surgical treatment,hepatic artery embolization was performed in the first stage.After 25 d of liver protection treatment,the liver function indexes decreased to normal levels.Then,ultrasound-guided microwave ablation of the giant hepatic hemangioma was performed.Ten days after the treatment,hepatobiliary ultrasonography showed that the hemangioma of the right liver was smaller than the previous size(the volume was reduced by approximately 30%).Then the patient was discharged from the hospital.One year after discharge,CT showed that the hepatic hemangioma had shrunk by about 80%CONCLUSION Transcatheter arterial embolization combined with microwave ablation is a safe and effective minimally invasive treatment for hepatic hemangioma.

A Minimally Invasive Surgery for Bone Metastases Using the Combination of Photodynamic Therapy and Hyperthermia Treatment

Cancer patients with bone metastases in their extremities may require surgical intervention to prevent deterioration in their quality of life due to a pathological fracture or severe bone pain. However, curative surgical interventions sometimes have severe complications due to the status of the original cancers. To avoid the decreased quality of life caused by bone metastasis, minimally invasive surgery that avoids additional surgical morbidity is required. We have established two therapeutic treatments for bone metastasis, a photodynamic acridine orange treatment (AOT) and an electronic magnetic hyperthermia treatment (EMHT). The present study investigated the clinical outcomes of combination therapy with EMHT and AOT for patients with bone metastases in their extremities. Methods: The study included 6 patients with 7 bone cancer metastasis locations. For bone metastases, all patients received intraregional tumor excision supported by AOT, in which photodynamic and radiodynamic therapy kills tumor cells during surgery with minimal damage to normal tissues. After the curettage, bone reconstruction was performed by using magnetic materials with calcium phosphate cement. EMHT was repeatedly performed after surgery. In EMHT, tumor cells are killed with an electric magnetic field generator, and bony union is promoted by electronic stimulation. Results: The mean duration of follow-up was 14 months. During the follow-up period, only one patient experienced a local recurrence, and this recurrence occurred 14 months after surgery. Bony union occurred in 4 of 5 cases (80%), and the pain score was significantly reduced after surgery. Conclusions: In the present study, AOT reduced the invasiveness of surgery. EMHT reduced the tumor growth without major complications and promoted bone formation after surgery. Our clinical results confirmed that EMHT and AOT combination therapy for bone metastasis can preserve limb function without local recurrence or bone absorption.

Trends of Noninvasive Radiofrequency and Minimally Invasive Treatment for the Management of Facial Aging

Various treatments for the management of facial aging have been performed among which noninvasive radio-frequency (RF;i.e., thermage) treatment and minimally invasive treatments are on the rise. The purpose of this study was to analyze trends of the treatment of facial aging in Korea and to investigate relationships between the use of noninvasive RF and minimally invasive treatments. A retrospective analysis conducted on data from 4021 patients showed that thermage treatment increased by 134.9% over 5 years. As a person ages, the rate of facial treatment with both the botulinum toxin (for the masseter and lines of the glabella, lateral canthus, and forehead) and the PDO thread lift increases. The use of the treatments, nasolabial fold filler and Silhouette Soft Thread, however, was not associated with aging. The patients receiving thermage treatment were less likely to undergo any of the other treatments including PDO thread lift, Silhouette Soft Thread, nasolabial fold filler, or any of the botulinum toxin treatments. Overall, the results showed that patients who had received noninvasive RF tended to receive less minimally invasive treatment.

New direction for surgery:Super minimally invasive surgery

The top goal of modern medicine is treating disease without destroying organ structures and making patients as healthy as they were before their sickness.Minimally invasive surgery(MIS)has dominated the surgical realm because of its lesser invasiveness.However,changes in anatomical structures of the body and reconstruction of internal organs or different organs are common after traditional surgery or MIS,decreasing the quality of life of patients post-operation.Thus,I propose a new treatment mode,super MIS(SMIS),which is defined as“curing a disease or lesion which used to be treated by MIS while preserving the integrity of the organs”.In this study,I describe the origin,definition,operative channels,advantages,and future perspectives of SMIS.

Advances in minimally invasive treatment of hemorrhagic and ischemic stroke

Cerebrovascular diseases,including ischemic and hemorrhagic strokes,affect more than 6 million US adults annually.Strokes cause high rates of morbidity and mortality due to the central nervous system’s sensitivity to disruptions in blood flow,and are refractory to traditional surgical interventions.A variety of minimally invasive surgical and endovascular approaches have recently been developed to improve patient outcomes following stroke.

Advances in Minimally Invasive Treatment of Benign Prostatic Hyperplasia

Benign prostatic hyperplasia (BPH) is a chronic condition that is more common in older men. BPH most commonly causes symptoms associated with LUTS and bladder outlet obstruction. Lower urinary tract symptoms (LUTS) in men with BPH are a major cause of reduced quality of life in older men. If bladder outlet obstruction persists for a longer period of time, the contractility and voiding capacity of the detrusor muscle will gradually be affected by the obstructive factors, eventually leading to a loss of compensatory phase, characterised by a reduced electrical stimulation response, replacement of bladder muscle tissue by connective tissue, and a possible increase in voiding pressure, but a decrease in contractility of the detrusor muscle. As BOO progresses, it eventually leads to permanent contractile dysfunction of the detrusor muscle. Therefore, early initiation of surgical treatment in patients who are not well controlled by medication can reduce the complications associated with prostate enlargement. With the rise of minimally invasive treatment and the complications of open surgery, minimally invasive treatment of BPH has attracted increasing attention. Various emerging minimally invasive surgical modalities are being developed in clinical practice, and more and more minimally invasive techniques and concepts are focusing on safety, improving quality of life and reducing long-term complications to meet the different needs of different patients. Transurethral resection of the prostate (TURP) is currently the “gold standard” of minimally invasive surgical treatment, but with concerns about post-operative complications, the search for safer and more effective minimally invasive surgical options has become even more important. In recent years, with the increasing clinical application of new minimally invasive techniques such as various lasers, interventional treatments and implantable devices, there are more options for minimally invasive treatment of BPH. This article provides a brief review of research advances in the minimally invasive treatment of benign prostatic hyperplasia, with a view to informing clinical decisions.

Minimally invasive method to treat a rare wrist injury with simultaneous fractures of the scaphoid and hook of hamate: A case report and literature review

Concomitant fractures of the hook of hamate and scaphoid are rare injuries to the wrist. Whenever these fractures cannot be effectively managed, nonunion or osteonecrosis is encountered. Subsequent treatment is thus much more challenging for a hand surgeon or orthopedist. Minimally invasive percutaneous internal fixation is an optimal treatment with the potential to minimize injury and reduce fractures. However, the control of iatrogenic injuries, including possible damage to the adjacent vital tissue, is a challenge that needs to be addressed. Herein,we describe the case of a 26-year-old man who presented with fractures to the scaphoid and hook of hamate in his left wrist. Minimally invasive treatment-with closed reduction and percutaneous fixation of the scaphoid, wrist arthroscopy, and closed reduction and percutaneous fixation of the hook of hamate-was performed at our institution. The Mayo score of the wrist, visual analog scale(VAS) for pain, grip strength, pinch strength, and wrist motion in radial/ulnar and flexion/extension deviation were recorded. Primary healing was achieved in both fractures. At the final follow-up, the Mayo score of the wrist was 100(excellent), the VAS score was 0(no pain),and the grip and pinch strength of his injured hand were 90.9% and 83.3%, respectively, compared with the contralateral hand(grip strength: left, 50 kg;right, 55 kg. Pinch strength: left, 20 kg;right, 24 kg). The radialulnar, flexion-extension, and forearm pronation-supination directions were 30°, 140°, and 90°, respectively.Minimally invasive closed reduction with percutaneous internal fixation is an optimal technique with satisfactory outcomes for simultaneous fractures of the hook of hamate and scaphoid. Provided in this paper are details of the technique and technical suggestions for performing the procedure.

Individualized minimally invasive treatment for adult testicular hydrocele: A pilot study

BACKGROUND Hydrocelectomy is the gold standard for the treatment of hydrocele,but it often causes complications after surgery,including hematoma,infection,persistent swelling,hydrocele recurrence,and chronic pain. In recent years,several methods for minimally invasive treatment of hydrocele have been introduced,but they all have limitations. Herein,we introduce a new method of individualized minimally invasive treatment for hydrocele.AIM To present a new method for the treatment of adult testicular hydrocele.METHODS Fifty-two adult patients with idiopathic testicular hydrocele were included. The key point of this procedure was that the scope of the resection of the sheath of the tunica vaginalis was determined according to the maximum diameter(d) of the effusion measured by ultrasound and the maximum diameter of the portion of the sheath pulled out of the scrotum was approximately πd/2. The surgical procedure consisted of a 2-cm incision in the anterior wall of the scrotum,drainage of the effusion,and dissection of part of the sheath of the tunica vaginalis. After the sheath was peeled away to the predetermined target extent,the pulled-out sheath was removed. The intraoperative findings and postoperative complications were analyzed.RESULTS All patients were successfully treated with a median operation time of 18 min.The median maximum diameter of the effusion on ultrasound was 3.5 cm,and the median maximum diameter of the resected sheath was 5.5 cm. Complications occurred in four(7.7%) patients: two(3.8%) cases of mild scrotal edema,one(1.9%) case of scrotal hematoma,and one(1.9%) case of wound infection. All of the complications were grade I-II. Recurrent hydrocele,chronic scrotal pain,and testicular atrophy were not observed during a median follow-up of 12 mo.CONCLUSION We report a new technique for individualized treatment of testicular hydrocele,which is quantitative and minimally invasive and yields good outcomes. Further study is warranted to verify its potential value in clinical practice.

Subtotal colonic bypass plus colostomy with antiperistaltic cecoproctostomy for the treatment of slow transit constipation in an aged population:A retrospective control study

AIM To compare the efficacy,improved quality of life,and prognosis in patients undergoing either subtotal colonic bypass with antiperistaltic cecoproctostomy(SCBAC) or subtotal colonic bypass plus colostomy with antiperistaltic cecoproctostomy(SCBCAC) for the treatment of slow transit constipation.METHODS Between October 2010 and October 2014,aged patients with slow transit constipation who were hospitalized and underwent laparoscopic surgery in our institute weredivided into two groups: the bypass group,15 patients underwent SCBAC,and the bypass plus colostomy group,14 patients underwent SCBCAC. The following preoperative and postoperative clinical data were collected: gender,age,body mass index,operative time,first flatus time,length of hospital stay,bowel movements(BMs),Wexner fecal incontinence scale,Wexner constipation scale(WCS),gastrointestinal quality of life index(GIQLI),numerical rating scale for pain intensity(NRS),abdominal bloating score(ABS),and ClavienDindo classification of surgical complications(CD) before surgery and at 3,6,12,and 24 mo after surgery.RESULTS All patients successfully underwent laparoscopic surgery without open surgery conversion or surgeryrelated death. The operative time and blood loss were significantly less in the bypass group than in the bypass plus colostomy group(P = 0.007). No significant differences were observed in first flatus time,length of hospital stay,or complications with CD > 1 between the two groups. No patients had fecal incontinence after surgery. At 3,6,and 12 mo after surgery,the number of BMs was significantly less in the bypass plus colostomy group than in the bypass group. The parameters at 3,6,12,and 24 mo after surgery in both groups significantly improved compared with the preoperative conditions(P < 0.05),except NRS at 3,6 mo after surgery in both groups,ABS at 12,24 mo after surgery and NRS at 12,24 mo after surgery in the bypass group. WCS,GIQLI,NRS,and ABS significantly improved in the bypass plus colostomy group compared with the bypass group at 3,6,12,and 24 mo after surgery(P < 0.05) except WCS,NRS at 3,6 mo after surgery and ABS at 3 mo after surgery. At 1 year after surgery,a barium enema examination showed that the emptying time was significantly better in the bypass plus colostomy group than in the bypass group(P = 0.007).CONCLUSION Laparoscopic SCBCAC is an effective and safe procedure for the treatment of slow transit constipation in an aged population and can significantly improve the prognosis. Its clinical efficacy is more favorable compared with that of SCBAC. Laparoscopic SCBCAC is a better procedure for the treatment of slow transit constipation in an aged population.

Clinical efficacy of integral theory–guided laparoscopic integral pelvic floor/ligament repair in the treatment of internal rectal prolapse in females

BACKGROUND Internal rectal prolapse(IRP)is one of the most common causes of obstructive constipation.The incidence of IRP in women is approximately three times that in men.IRP is mainly treated by surgery,which can be divided into two categories:Abdominal procedures and perineal procedures.This study offers a better procedure for the treatment of IRP.AIM To compare the clinical efficacy of laparoscopic integral pelvic floor/ligament repair(IPFLR)combined with a procedure for prolapse and hemorrhoids(PPH)and the laparoscopic IPFLR alone in the treatment of IRP in women.METHODS This study collected the clinical data of 130 female patients with IRP who underwent surgery from January 2012 to October 2014.The patients were divided into groups A and B.Group A had 63 patients who underwent laparoscopic IPFLR alone,and group B had 67 patients who underwent the laparoscopic IPFLR combined with PPH.The degree of internal rectal prolapse(DIRP),Wexner constipation scale(WCS)score,Wexner incontinence scale(WIS)score,and Gastrointestinal Quality of Life Index(GIQLI)score were compared between groups and within groups before surgery and 6 mo and 2 years after surgery.RESULTS All laparoscopic surgeries were successful.The general information,number of bowel movements before surgery,DIRP,GIQLI score,WIS score,and WCS score before surgery were not significantly different between the two groups(all P>0.05).The WCS score,WIS score,GIQLI score,and DIRP in each group 6 mo,and 2 years after surgery were significantly better than before surgery(P<0.001).In group A,the DIRP and WCS score gradually improved from 6 mo to 2 years after surgery(P<0.001),and the GIQLI score progressively improved from 6 mo to 2 years after surgery(P<0.05).In group B,the DIRP,WCS score and WIS score significantly improved from 6 mo to 2 years after surgery(P<0.05),and the GIQLI score 2 years after surgery was significantly higher than that 6 mo after surgery(P<0.05).The WCS score,WIS score,GIQLI score,and DIRP of group B were significantly better than those of group A 6 mo and 2 years after surgery(all P<0.001,Bonferroni)except DIRP at 2 years after surgery.There was a significant difference in the recurrence rate of IRP between the two groups 6 mo after surgery(P=0.011).There was no significant difference in postoperative grade I-III complications between the two groups(P=0.822).CONCLUSION Integral theory–guided laparoscopic IPFLR combined with PPH has a higher cure rate and a better clinical efficacy than laparoscopic IPFLR alone.

Midline Prostatic Cysts Presenting with Chronic Prostatitis or Secondary Infertility and Minimally Invasive Treatment: Endoscopic or Laparoscopic Approach?

Backgrounds: Surgical interventions especially minimally invasive treatments are recommended for symptomatic midline prostatic cysts. The endoscopic unroofing of cysts close to urethra is easy and simple, but it has little effect on the large cysts and cysts lying deeply, in contrast with the laparoscopic approach. Therefore, the selection of minimally invasive therapeutic approaches is important. The aim of this study is to describe our experience in the diagnosis and selection of minimally invasive treatment for midline prostatic cyst. Methods: 15 cases of midline prostatic cyst were studied.10 cases presented with prostatitis-like symptoms, 1 with dysuria and acute urinary retention, 3 with secondary infertility and the rest 1 with hemospermia. 6 patients presented with small cysts (≤2 cm × 2 cm) close to urethra and underwent transurethral unroofing. The other 9 patients with large cysts (>2 cm × 2 cm) or cysts lying closely behind the prostate received the laparoscopic excision. Results: The average duration of transurethral unroofing and laparoscopic excision was 39 mins and 118 mins respectively, whereas the average time of hospitalization was 2.7 days and 4.5 days respectively. After a follow-up of 21 months, all cases were treated successfully without complications and recurrence. Their prostatitis-like symptoms disappeared, and the three patients presented with secondary infertility achieved conception within one year after the operation. Conclusions: A midline prostatic cyst can present with chronic prostatitis-like symptoms and secondary infertility. It can be cured by minimally invasive treatments, but these procedures should be carefully selected according to the size and location of the cyst.

Clinical Application of Minimally Invasive Surgery in Pain and Complications after Spinal Trauma

Objective:To study and evaluate the incidence of pain and complications in patients with spinal trauma after minimally invasive treatment.Methods:The research period was selected from January 2018 to December 2020,and 40 patients with spinal trauma were selected.According to the random number table scheme,they were divided into the study group and the control group.The treatment scheme of the control group was traditional surgery,and the treatment scheme of the study group was minimally invasive surgery.The indicators of the two groups were compared and analyzed.Results:Compared with the two groups of surgery and postoperative recovery related indicators,the study group had more advantages(P<0.05);Compared two groups of postoperative NRS score,VAS score and the incidence of complications,the study group had more advantages(P<0.05).Conclusion:Minimally invasive treatment of spinal trauma has significant clinical effect,which can effectively relieve postoperative pain and reduce the incidence of various complications.

Pancreatic necrosis:Complications and changing trend of treatment

Incidence of acute pancreatitis seems to be increasing in the Western countries and has been associated with significantly increased morbidity. Nearly 80% of the patients with acute pancreatitis undergo resolution; some develop complications including pancreatic necrosis. Infection of pancreatic necrosis is the leading cause of death in these patients. A significant portion of these patients needs surgical interventions. Traditionally, the "gold standard" procedure has been the open surgical necrosectomy, which is now being completed by the relatively lesser invasive interventions. Minimally invasive surgical(MIS) procedures include endoscopic drainage, percutaneous image-guided catheter drainage, and retroperitoneal drainage. This review article discusses the open and MIS interventions for pancreatic necrosis with each having its own respective benefits and disadvantages are covered.

Current status of esophageal cancer treatment

Esophageal cancer(EC) remains one of the most common and aggressive diseases worldwide.This review discusses some debates in the modern management of the disease.Endoscopic procedures for early cancer(T1a-b) are now embedded in routine care and the challenge will be to more accurately select patients for endoscopic resection with or without adjuvant therapy.Perioperative multimodal therapies are associated with improved survival compared to surgery alone for locally advanced esophageal cancer.However, there is no global consensus on the optimal regimen.Furthermore, histological subtype(adenocarcinoma vs.squamous cell cancer) plays a role in the choice for treatment.New studies are underway to resolve some issues.The extent of the lymphadenectomy during esophagectomy remains controversial especially after neoadjuvant chemoradiation.The ideal operation balances between limiting surgical trauma and optimizing survival.Minimally invasive esophagectomy and enhanced recovery pathways are associated with decreased morbidity and faster recovery albeit there is no consensus yet what approach should be used.Finally, immune checkpoint inhibitors present promising preliminary results in the novel treatment of advanced or metastatic EC but their widespread application in clinical practice is still awaited.

Surgical treatment of gastric cancer:Current status and future directions

Surgery is the most important and effective method for the treatment of gastric cancer.Since the first gastrectomy in the early 19th century,surgical treatment of gastric cancer has undergone more than 100 years of development.With the increasing understanding of gastric cancer and the promotion of a series of clinical trials,the concept of gastric cancer surgery has evolved from the initial"bigger is better"to today’s"standardized surgery"and is developing towards individualized surgery focusing on accurate resection and quality of life.This trend has had a tremendous impact on the development of surgical treatments,such as minimally invasive surgeries,functionpreserving surgeries,and the optimal extent of lymph node dissection.Understanding the development and current status of gastric cancer surgery and exploring the remaining academic controversies are goals that every gastric surgeon should constantly pursue.However,how should gastric cancer surgery develop in the future?What opportunities and challenges will we encounter?In this review,we elaborate on the development and current status of gastric cancer surgery based on a series of clinical studies and discuss the controversy in the development of gastric cancer surgery.

Min-invasive surgical treatment for multiple axis fractures: A case report

BACKGROUND Fractures of the axis are commonly seen in spinal injuries. Upper cervical fractures are usually managed conservatively. However, the complications due to long-term external immobilization cannot be ignored. The traditional open surgery has the disadvantages of too much blood loss and soft tissue injury. The aim of our paper is to introduce a minimally invasive surgical treatment for multiple axis fractures.CASE SUMMARY We report a 40-year-old Chinese male who had severe neck pain and difficult neck movement after falling from 3 meters. X-ray and computed tomography(CT) scan revealed an axis injury consisting of an odontoid Type Ⅲ fracture associated with a Hangman fracture categorized as a Levine-Edwards Type Ⅰ fracture. The patient underwent anterior odontoid screw fixation and posterior percutaneous screw fixation using intraoperative O-arm navigation. Neck pain was markedly improved after surgery. X-rays and CT scan reconstructions of 3-mo follow-up showed good stability and fusion. The range of cervical motion was well preserved.CONCLUSION Anterior odontoid screw fixation and posterior direct C2 percutaneous pedicle screw fixation with the aid of O-arm navigation and neurophysiological monitoring can be an interesting alternative option for complicated multiple axis fractures.

Management of BPH then 2000 and now 2016-From BPH to BPO

The diagnosis and treatment of benign prostatic obstruction(BPO)is based on a number of well-known lower urinary tract symptoms(LUTS)feared by all ageing males with functional testes.The ascent of modern urology turned this disease from lethal into an annoying but treatable health problem in the previous century.We are able to relieve the great majority of patients from their bothersome symptoms to a respectable quality of life by medication or removal of the obstructive part of the enlarged prostate.We can be proud of some progress made in the new millennium to reach a correct diagnosis and subsequent choice of treatment aiming for quality of life and cost-efficiency for public health.Still it remains symptomatic treatment and we expect the new generation of urologists to close some gaps in our knowledge on the regulation of prostatic growth to focus on prevention and elimination of the disease in the foreseeable future.
