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.

Incidence of surgical site infection in minimally invasive colorectal surgery

BACKGROUND Surgical site infection(SSI)is a common complication of colorectal surgery.Minimally invasive surgery notably reduces the incidence of SSI.This study aimed to compare the incidences of SSI after robot-assisted colorectal surgery(RACS)vs that after laparoscopic assisted colorectal surgery(LACS)and to analyze associated risk factors for SSI in minimally invasive colorectal surgery.AIM To compare the incidences of SSI after RACS and LACS,and to analyze the risk factors associated with SSI after minimally invasive colorectal surgery.METHODS Clinical data derived from patients who underwent minimally invasive colorectal surgery between October 2020 and October 2022 at the First Affiliated Hospital of Soochow University were collated.Differences in clinical characteristics and surgeryrelated information associated with RACS and LACS were compared,and possible risk factors for SSI were identified.RESULTS A total of 246 patients(112 LACS and 134 RACS)were included in the study.Fortythree(17.5%)developed SSI.The proportions of patients who developed SSI were similar in the two groups(17.9%vs 17.2%,P=0.887).Diabetes mellitus,intraoperative blood loss≥100 mL,and incision length were independent risk factors for SSI.Possible additional risk factors included neoadjuvant therapy,lesion site,and operation time.CONCLUSION There was no difference in SSI incidence in the RACS and LACS groups.Diabetes mellitus,intraoperative blood loss≥100 mL,and incision length were independent risk factors for postoperative SSI.

Efficacy and safety of minimally invasive laparoscopic surgery under general anesthesia for ovarian cancer

BACKGROUND Ovarian cancer is one of the most common malignant tumors in female reproductive system in the world,and the choice of its treatment is very important for the survival rate and prognosis of patients.Traditional open surgery is the main treatment for ovarian cancer,but it has the disadvantages of big trauma and slow recovery.With the continuous development of minimally invasive technology,minimally invasive laparoscopic surgery under general anesthesia has been gradually applied to the treatment of ovarian cancer because of its advantages of less trauma and quick recovery.However,the efficacy and safety of minimally invasive laparoscopic surgery under general anesthesia in the treatment of ovarian cancer are still controversial.AIM To explore the efficacy and safety of general anesthesia minimally invasive surgery in the treatment of ovarian cancer.METHODS The clinical data of 90 patients with early ovarian cancer in our hospital were analyzed retrospectively.According to the different surgical treatment methods,patients were divided into study group and control group(45 cases in each group).The study group received minimally invasive laparoscopic surgery under general anesthesia for ovarian cancer,while the control group received traditional open surgery for ovarian cancer.The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30),clinical efficacy and safety of the two groups were compared.RESULTS The intraoperative blood loss,length of hospital stay,postoperative gas evacuation time,and postoperative EORTC QLQ-C30 score of the study group were significantly better than those of the control group(P<0.05).The incidence of postoperative complications in the study group was significantly lower than in the control group(P<0.05).The two groups had no significant differences in the preoperative adrenocorticotropic hormone(ACTH),androstenedione(AD),cortisol(Cor),cluster of differentiation 3 positive(CD3+),and cluster of differentiation 4 positive(CD4+)indexes(P>0.05).In contrast,postoperatively,the study group's ACTH,AD,and Cor indexes were lower,and the CD3+and CD4+indexes were higher than those in the control group(P<0.05).CONCLUSION Minimally invasive laparoscopic surgery under general anesthesia in patients with early ovarian cancer can significantly improve the efficacy and safety,improve the short-term prognosis and quality of life of patients,and is worth popularizing.

Gastric cancer surgery in South Korea: Past, present, and future

Gastric cancer remains a significant global health concern and its surgical management approaches have undergone significant changes in South Korea and worldwide. Subtotal or total gastrectomy with D2 lymph node dissection is well established as a standard surgical procedure for gastric cancer. With the active implementation of cancer screening in South Korea, the proportion of early gastric cancer cases has significantly increased over the past few decades, leading to a steady increase in the survival rate among patients. Furthermore, recent advances in surgical instruments and techniques have made minimally invasive surgery increasingly prevalent, not only for early but also for advanced gastric cancer. We aim to provide a comprehensive overview of the evolution and current status of gastric cancer surgery in South Korea.

Transanal endoscopic microsurgery as optimal option in treatment of rare rectal lesions:a single centre experience

AIM To analyze the outcomes of transanal endoscopic microsurgery(TEM) in the treatment of rare rectal condition like mesenchymal tumors, condylomas, endometriosis and melanoma. METHODS We retrospectively reviewed a twenty-three years database. Fifty-two patients were enrolled in this study. The lesions were considered suitable for TEM if they were within 20 cm from the anus. All of them underwent an accurate preoperative workup consisting in clinical examination, total colonoscopy with biopsies, endoscopic ultrasonography, and pelvic computerized tomography or pelvic magnetic resonance imaging. Operative time, intraoperative complications, rate of conversion, tumor size, postoperative morbidity, mortality, the length of hospital stay, local and distant recurrence were analyzed.RESULTS Among the 1328 patients treated by TEM in our department, the 52 patients with rectal abnormalities other than adenoma or adenocarcinoma represented 4.4%. There were 30 males(57.7%) and 22 females(42.3%). Mean age was 55 years(median = 60, range = 24-78). This series included 14(26.9%) gastrointestinal stromal tumors, 21 neuroendocrine tumors(40.4%), 1 ganglioneuroma(1.9%), 2 solitary ulcers in the rectum(3.8%), 6 cases of rectal endometriosis(11.5%), 6 cases of rectal condylomatosis(11.5%) and 2 rectal melanomas(3.8%). Mean lesion diameter was 2.7 cm(median: 4, range: 0.4-8). Mean distance from the anal verge was 9.5 cm(median: 10, range: 4-15). One patient operated for rectal melanoma developed distant metastases and died two years after the operation. We experienced 2 local recurrences(3.8%) with an overall survival equal to 97.6%(95%CI: 95%-99%) at the end of follow-up and a disease free survival of 98%(95%CI: 96%-99%).CONCLUSION We could conclude that TEM is an important therapeutical option for rectal rare conditions.

Background,techniques,applications,current trends,and future directions of minimally invasive endoscopic spine surgery:A review of literature

Across many of the surgical specialties,the use of minimally invasive techniques that utilize indirect visualization has been increasingly replacing traditional techniques which utilize direct visualization.Arthroscopic surgery of the appendicular skeleton has evolved dramatically and become an integral part of musculoskeletal surgery over the last several decades,allowing surgeons to achieve similar or better outcomes,while reducing cost and recovery time.However,to date,the axial skeleton,with its close proximity to critical neural and vascular structures,has not adopted endoscopic techniques at as rapid of a rate.Over the past decade,increased patient demand for less invasive spine surgery combined with surgeon desire to meet these demands has driven significant evolution and innovation in endoscopic spine surgery.In addition,there has been an enormous advancement in technologies that assist in navigation and automation that help surgeons circumvent limitations of direct visualization inherent to less invasive techniques.There are currently a multitude of endoscopic techniques and approaches that can be utilized in the treatment of spine disorders,many of which are evolving rapidly.Here we present a review of the field of endoscopic spine surgery,including the background,techniques,applications,current trends,and future directions,to help providers gain a better understanding of this growing modality in spine surgery.

Robotic surgery in elderly patients with colorectal cancer: Review of the current literature

With an ageing global population,we will see an increasing number of elderly patients with colorectal cancer(CRC)requiring surgery.However,it should be recognized that the elderly are a heterogenous group,with varying physiological and functional status.While traditionally viewed to be associated with frailty,comorbidities,and a higher risk of post operative morbidity,the advancements in minimally invasive surgery(MIS)and improvements in perioperative care have allowed CRC surgery to be safe and feasible in the elderly-chronological age alone should therefore not strictly be an exclusion criterion for curative surgery.However,as a form of MIS,laparoscopic assisted colorectal surgery(LACS)has the inherent disadvantages of:(1)Dependence on a trained assistant for retraction and laparoscope control;(2)The loss of wristed movement with reduced dexterity and suboptimal ergonomics;(3)A lack of intuitive movement due to the levering effect of trocars;and(4)An amplification of physiological tremors.Representing a technical evolution of LACS,robotic assisted colorectal surgery was introduced to overcome these limitations.In this minireview,we examine the evidence for robotic surgery in the elderly with CRC.

Minimally Invasive Maxillofacial Surgery Using Digital Work Surgery: A Case of Alveolar Ridge Reconstruction after Maxillary Cystectomy

Introduction: Iliac particulate cancellous bone and marrow (PCBM) is commonly used as a high-quality reconstruction material;however, PCBM cannot be extracted in sufficient amounts to meet demand. To determine the appropriate amount of iliac PCBM to be collected, we used digital technology to measure the volume required for jaw reconstruction before surgery. Clinical Case: The patient, a 23-year-old man, underwent surgery for a calcifying odontogenic cyst. A maxillary cyst occupied the left anterior-premolar region (tooth 21 - 25) and the deciduous canine remained;a permanent canine was included in the cyst. We planned to preserve the teeth except for the impacted canine, completely excise the maxillary cyst, and preserve the alveolar ridge morphology. Preoperative digital imaging was used to determine the amount of alveolar ridge reconstruction required and accordingly determine the amount of iliac cancellous bone to be harvested. We used a titanium mesh tray and grafts of iliac particulate cancellous bone and marrow to reconstruct the alveolar ridge. The amount of iliac cancellous bone that needed to be collected was clarified and the supply amount could be collected in just the right amount;thus, the cortical bone of the iliac inner plate could be preserved. The alveolar bone morphology was reconstructed to allow the placement of dental implants as per the preoperative digital surgery. Three years after the operation, no sign of recurrence has been observed. Conclusion: Minimally invasive surgery was performed by clarifying the amount of iliac cancellous bone graft that needs to be harvested, which improved the accuracy of surgery.

Removal of a large rectal polyp with endoscopic submucosal dissection-trans-anal rectoscopic assisted minimally invasive surgery hybrid technique:A case report

BACKGROUND Endoscopic submucosal dissection(ESD)can be used for the en-bloc removal of superficial rectal lesions;however,the lack of a traction system makes the procedure long and difficult in the presence of extensive lesions.CASE SUMMARY A large polyp occupying 2/3 of the rectal circumference and extending 5 cm in length was removed by ESD with the help of laparoscopic forceps introduced via trans-anal rectoscopic assisted minimally invasive surgery,a disposable platform designed to aid in transanal minimally invasive surgery.Traction of the polyp by forceps during the operation was dynamic,and applied at various points and in various directions.The polyp was removed en-bloc without complications in 1 h and 55 min.A sigmoidoscopy performed 50 d later showed normal healing without polyp recurrence.CONCLUSION The technique presented here could overcome the issues caused by lack of traction during ESD for rectal lesions.

Comparison of minimally invasive glaucoma surgery with trabecular micro-bypass stent and microhook ab interno trabeculotomy performed in conjunction with cataract surgery

AIM: To evaluate the effectuality and safety of cataract surgery combined with either ab interno trabeculotomy by the microhook(μLOT) or a single i Stent? trabecular bypass implantation(i Stent) in eyes with cataract and mild-tomoderate glaucoma. METHODS: This study enrolled subjects with mild-tomoderate open angle glaucoma with visually significant cataract who used two or more ophthalmic antiglaucoma agents between 60 and 90 y of age. Patients underwent cataract surgery cooperated with either implantation of an i Stent(i Stent-phaco) or excisional goniotomy with the μLOT(μLOT-phaco). Patients underwent μLOT-phaco in the eye with lower the mean deviation, according to the Humphrey field analyzer, while i Stent-phaco was carried out on the other eye. Intraocular pressure(IOP) pre-and post-surgery, alterations in anterior chamber flare(ACF), and corneal endothelial cell density(ECD) were estimated.RESULTS: Twenty subjects were enrolled(mean age: 73.6±7.3 y). The mean medicated preoperative IOP was 16.7 mm Hg in the μLOT and 16.2 mm Hg in the i Stent eyes. The mean final IOP at 12 mo was 13.6 mm Hg in the μLOT eyes and 13.6 mm Hg in the i Stent eyes, representing a 17.8% and 17.2% reduction, respectively. The preoperative ACF in the μLOT eyes was 9.5 pc/ms and it returned to normal in 30 d postoperatively, with a value of 11.4 pc/ms. In the i Stent eyes, ACF was 9.6 pc/ms preoperatively and it returned to normal by 7 d postoperatively(11.2 pc/ms atday 7), demonstrating that postoperative inflammation was less in the i Stent eyes. The corneal ECD in both groups was not significantly decreased.CONCLUSION: In this study, i Stent and μLOT are both effective through 12 mo of follow-up. Safety is more favorable in the i Stent eyes, based on early anterior chamber inflammation.

Current developments in natural orifices transluminal endoscopic surgery:An evidence-based review

Tremendous advances have been made in recent years addressing the key obstacles to safe performance and introduction of human natural orifice transluminal endoscopic surgery (NOTES). Animal studies have focused on identifying optimal solutions to these obstacles, in particular methods of creating transluminal access,safe closure of the point of access, and development of a multitasking platform with dedicated instruments. Whether the performance data generated from these animal studies can be reproduced in humans has yet to be determined. Reports of human NOTES procedures are emerging, and the possibility of accomplishing human NOTES based on existing technology has been demonstrated. However, dedicated platforms and devices are still lacking to allow for pure NOTES procedures, and whether NOTES can deliver the postulated benef its of earlier recovery and improved cosmesis remains uncertain.

Role of minimally invasive surgery for rectal cancer

Rectal cancer is one of the most common malignancies worldwide.Surgical resection for rectal cancer usually requires a proctectomy with respective lymphadenectomy(total mesorectal excision).This has traditionally been performed transabdominally through an open incision.Over the last thirty years,minimally invasive surgery platforms have rapidly evolved with the goal to accomplish the same quality rectal resection through a less invasive approach.There are currently three resective modalities that complement the traditional open operation:(1)Laparoscopic surgery;(2)Robotic surgery;and(3)Transanal total mesorectal excision.In addition,there are several platforms to carry out transluminal local excisions(without lymphadenectomy).Evidence on the various modalities is of mixed to moderate quality.It is unreasonable to expect a randomized comparison of all options in a single trial.This review aims at reviewing in detail the various techniques in regard to intra-/perioperative benchmarks,recovery and complications,oncological and functional outcomes.

Safety considerations in laparoscopic surgery: A narrative review

Laparoscopic surgery has many advantages over open surgery.At the same time,it is not without its risks.In this review,we discuss steps that could enhance the safety of laparoscopic surgery.Some of the important safety considerations are ruling out pregnancy in women of the childbearing age group;advanced discussion with the patient regarding unexpected intraoperative situations,and ensuring appropriate equipment is available.Important perioperative safety considerations include thromboprophylaxis;antibiotic prophylaxis;patient allergies;proper positioning of the patient,stack,and monitor(s);patient appropriate pneumoperitoneum;ergonomic port placement;use of lowest possible intra-abdominal pressure;use of additional five-millimetre(mm)ports as needed;safe use of energy devices and laparoscopic staplers;low threshold for a second opinion;backing out if unsafe to proceed;avoiding hand-over in the middle of the procedure;ensuring all planned procedures have been performed;inclusion of laparoscopic retrieval bags and specimens in the operating count;avoiding 10-15 mm ports for placement of drains;appropriate port closures;and use of long-acting local anaesthetic agents for analgesia.Important postoperative considerations include adequate analgesia;early ambulation;careful attention to early warning scores;and appropriate discharge advice.

Spleen-preserving distal pancreatectomy from multi-port to reducedport surgery approach

BACKGROUND Minimally invasive pancreatic surgery via the multi-port approach has become a primary surgical method for distal pancreatectomy(DP)due to its advantages of lower wound pain and superior cosmetic results.Some studies have applied reduced-port techniques for DP in an attempt to enhance cosmetic outcomes due to the minimally invasive effects.Numerous recent review studies have compared multi-port laparoscopic DP(LDP)and multi-port robotic DP(RDP);most of these studies concluded multi-port RDP is more beneficial than multi-port LDP for spleen preservation.However,there have been no comprehensive reviews of the value of reduced-port LDP and reduced-port RDP.AIM To search for and review the studies on spleen preservation and the clinical outcomes of minimally invasive DP that compared reduced-port DP surgery with multi-port DP surgery.METHODS The PubMed medical database was searched for articles published between 2013 and 2022.The search terms were implemented using the following Boolean search algorithm:(“distal pancreatectomy”OR“left pancreatectomy”OR“peripheral pancreatic resection”)AND(“reduced-port”OR“single-site”OR“single-port”OR“dual-incision”OR“single-incision”)AND(“spleen-preserving”OR“spleen preservation”OR“splenic preservation”).A literature review was conducted to identify studies that compared the perioperative outcomes of reduced-port LDP and reduced-port RDP.RESULTS Fifteen articles published in the period from 2013 to 2022 were retrieved using three groups of search terms.Two studies were added after manually searching the related papers.Finally,10 papers were selected after removing case reports(n=3),non-English language papers(n=1),technique papers(n=1),reviews(n=1),and animal studies(n=1).The common items were defined as items reported in more than five papers,and data on these common items were extracted from all papers.The ten studies included a total of 337 patients(females/males:231/106)who underwent DP.In total,166 patients(females/males,106/60)received multi-port LDP,126(females/males,90/36)received reduced-port LDP,and 45(females/males,35/10)received reduced-port RDP.CONCLUSION Reduced-port RDP leads to a lower intraoperative blood loss,a lower postoperative pancreatic fistula rate,and shorter hospital stay and follow-up duration,but has a lower spleen preservation rate.

Is Anticoagulation Warranted after Left Atrial Appendage Ligation in Patients at Risk for Stroke after Cardiac Surgery?

Objectives: Left atrial appendage ligation (LAAL) may constitute alternative stroke prophylaxis in patients with atrial fibrillation (AF). Herein we describe the 30-day post discharge outcomes of cardiac surgery patients with elevated stroke risk with or without anticoagulation (AC) following epicardial LAAL. Methods: Data were reviewed for 479 consecutive adult patients who underwent epicardial LAAL from 2014-2019 (median CHA2DS2-VASc score = 4.0). There were 251 and 228 patients discharged with and without AC, respectively, who were followed for 30 days. Patients were matched via 1:1 Propensity Score Matching (PSM;n = 115 per group). Post-discharge outcomes included stroke, bleeding, readmission for cardiac re-intervention, mortality, and a composite endpoint comprised of the aforementioned outcomes. Results: There was no difference in post-discharge stroke incidence regardless of AC (adjusted cumulative incidence (ACI) 0.009 CI [0.001 - 0.043] with AC vs 0.009 CI [0.001 - 0.43] without AC;p = 0.826), post-discharge bleeding (ACI 0.018 CI [0.003 - 0.057] with AC vs 0.009 CI [0.001 - 0.046] without AC;p = 0.738), readmission for cardiac re-intervention (ACI 0.009 CI [0.009 - 0.009] with AC vs 0 CI [NA] without AC;p = 0.340, post-discharge mortality (ACI 0 CI NA with AC vs 0.009 CI [0.001 - 0.046] without AC;p = 0.123, or in the composite outcome (ACI 0.026 CI [0.007 - 0.069] with AC vs 0.027 CI [0.007 - 0.071] without AC;p = 0.824. Conclusion: Cessation of AC in patients with elevated stroke risk following epicardial LAAL during cardiac surgery does not affect stroke rate, mortality, or bleeding incidence up to 30 days post-discharge in this preliminary analysis.

The Use of Neuronavigation with Vasular Microdoppler in Transsphenoidal Pituitary Surgery

Object: To evaluate the use of neuronavigation with vascular micro-doppler in transsphenoidal pituitary surgery. Methods: 141 cases having done transsphenoidal pituitary surgery are evaluated from 2005 to 2014. Fluoroscopy was used in 69 cases and vascular micro-doppler with neuronavigation were used in 72 cases. Results: Transsphenoidal surgery has a lot of risks due to sella’s deep location, and position of the carotid artery and the optic nerve. Clasically the fluoroscopy and microscopic anatomical markers were used in order to minimize the risk of carotid artery and optic nerve damage. Additional devices such as neuronavigation and vascular micro-doppler are needed to decrease the morbidity and mortality arising from these injuries. Conclusion: Neurovascular complications such as carotid artery and optic nerve injuries owing to disorientation in transsphenoidal surgery will reduce the use of neuronavigation with vascular micro-doppler.

Natural orifice transluminal endoscopic surgery in urology: The Chinese experience

Objective:To describe the Chinese experience of natural orifice transluminal endoscopic surgery(NOTES)in urology.Methods:From December 2008 to May 2017,35 animal experiments and 305 clinical surgeries of NOTES or natural orifices specimen extractions(NOSE)were performed in China.The animal experiments included five kidney biopsies,24 nephrectomies and six partial nephrectomies.The clinical surgeries included 12 transvaginal NOSE(TV-NOSE),266 hybrid transvaginal NOTES(TV-NOTES)and 27 pure TV-NOTES.The TV-NOSE procedure was performed in five transumbilical laparoendoscopic single-site(U-LESS)nephrectomies,four suprapubic-assisted laparoendoscopic single-site surgery(SA-LESS)nephroureterectomies,and three laparoscopic radical cystectomies.The hybrid TV-NOTES procedure included 210 nephrectomies,31 adrenalectomies,eight nephroureterectomies,13 partial nephrectomies,and four heminephrectomies.The pure TV-NOTES procedure included five renal cyst decortications and 22 nephrectomies.Results:A total of 29 animal experiments were successfully performed.One partial nephrectomy was converted to standard laparoscopic surgery.Two kidney biopsies and two nephrectomies were unsuccessful.A total of 297 clinical surgeries were successfully performed.Six patients who underwent hybrid TV-NOTES were converted to open surgery.Two patients who underwent pure TV-NOTES were converted to SA-LESS.There were 22 major complications,16 occurred intraoperatively and six postoperatively.The mean visual analog score(VAS)of 48 h after the operation was 2.5 points in TV-NOSE,2.3 points in hybrid TV-NOTES and 1.7 points in pure TV-NOTES.The mean follow-up of 50.6(3.0-87.0)months showed that all patients were in good condition.The umbilicus scars were nearly invisible in TV-NOSE and hybrid TV-NOTES.The vaginal incision healed well.Conclusions:TV-NOSE and TV-NOTES are feasible,safe,and effective with little injury,low pain,fast recovery,and good cosmetic outcomes in properly selected patients.They are worth consideration for urological clinical practice.

Open surgery in the era of minimally invasive surgery

The benefits and popularity of minimally invasive surgery are undeniable around the globe.However,open surgery is necessary and learning open surgery skills is still a necessity.Open surgery allows for better exposure to the surgical field and provides tactile sensation to facilitate the stereo visual assessment to precisely remove the lesion.Open surgery is still the key to surgical training,and the skills learned from open surgeries remain crucial for unforeseen circumstances and certain conditions like emergencies,challenge cases,or patients with compromised status.
