Different surgical procedures were selected according to the angle of head turn in 44 cases of HIN with abnormal head posture and strabismus. For patients with a head turn of 15° or less, the Anderson procedure was used; the yoke muscles were recessed upon slow-phase. For patients with a head turn between 15° and 25°, the surgery was designed as a Kestenbaum 5-4-4-5 procedure. For patients with a head turn of 25° or more, the surgery was designed as a Parks 5-8-6-7 procedure. The surgery to correct the abnormal head posture was performed on the fixating eye while that to correct the deviation was then performed on the non-fixating eye at the same time. The amount of surgery of the horizontal rectus muscles on the nonfixating eye was sum of the angle of head turn and the degree of deviation, which was calculated as follows: recession/resection amount of medial and lateral rectis/2×5=angle of head turn±degree of deviation. The results showed as follows: (1) Visual acuity: the visual acuity in the primary ocular position increased two lines or more in 35 patients, accounting for 79.55%. Nine patients had no or only one-line improvement, accounting for 20.45% of the entire study population; (2) The degree of deviation in the primary ocular position: 37 cases had a normal primary ocular position or the degree of deviation ≤8△ after surgery, accounting for 84.09%. Six patients had a residual degree of deviation of 8△―15△, accounting for 13.64%. One patient had a residual degree of deviation 〉20△, accounting for 2.27% of the patients examined; (3) Abnormal head posture: 34 patients had a normal head posture or a head turn of less than 5°, accounting for 72.27%. Eight patients had a residual head turn of 5°―15°, accounting for 18.18%. Two patients had a head turn of 15°― 25°, accounting for 4.55%. It was concluded that different surgical procedures based on the angle of head turn and the relationship between deviation and null zone can eliminate anomalous head posture, correct deviation, and improve vision acuity in the primary ocular position simultaneously.展开更多

METHODS: Patients underwent horizontal strabismus surger y were enrolled prospectively. Retinal vessel diameters on color fundus photographs were assessed before and 1, 7 d, 6 mo after surgery, using a computerassisted quantitative assessment software. To evaluate the retinal vascular caliber changes, retinal vascular diameters were calculated by means of the Parr–Hubbard formula as the central retinal arteriolar equivalent(CRAE) and central retinal venular equivalent(CRVE). The arteriovenous ratio(AVR) was calculated as CRAE divided by CRVE. RESULTS: A total of 154 eyes of 104 consecutive patients were included. Compared with the data before surgery(121.55±24.67), the mean CRAE(131.18±28.29) significantly increased 1 d af ter surger y(P=0.003), but went back to baseline level at 7 d(118.89±30.35, P=0.15), and 6 mo(123.22±15.32, P=0.60), so did the AVR(P<0.001, P=0.08, P=0.07). As for the mean CRVE, there was no significant difference between those four time points(172.43±33.25, 175.57±36.98, 174.03±40.18, 174.86±20.46, P=1.00). CONCLUSION: Strabismus surgery on both lateral and media rectus muscles, or single media rectus muscle may increase retinal blood flow during the early postoperative period, but would return to normal later. The number of transected anterior ciliary arteries rather might be the main cause of retinal hemodynamic changes early after strabismus surgery.展开更多

Current applications remain restricted to determining limbus-muscle insertion distance and anterior segment changes after strabismus surgery. We discuss two cases of operated strabismus surgery where AS-OCT imaging helped in identifying the operated eye and/or extra ocular muscles (EOM) and thus proved instrumental in planning and management.展开更多

However, the underlying pathogenesis and visual defects are still not fully understood. Most studies have used experimental interference to establish diseaseassociated animal models, while ignoring the natural pathophysiological mechanisms. This study was designed to investigate whether natural strabismus and amblyopia are associated with abnormal neurological defects. We screened one natural strabismic monkey(Macaca fascicularis) and one natural amblyopic monkey from hundreds of monkeys, and retrospectively analyzed one human strabismus case. Neuroimaging, behavioral,neurophysiological, neurostructural, and genovariation features were systematically evaluated using magnetic resonance imaging(MRI), behavioral tasks, flash visual evoked potentials(FVEP),electroretinogram(ERG), optical coherence tomography(OCT), and whole-genome sequencing(WGS), respectively. Results showed that the strabismic patient and natural strabismic and amblyopic monkeys exhibited similar abnormal asymmetries in brain structure, i.e., ipsilateral impaired right hemisphere. Visual behavior, visual function, retinal structure, and fundus of the monkeys were impaired. Aberrant asymmetry in binocular visual function and structure between the strabismic and amblyopic monkeys was closely related, with greater impairment of the left visual pathway.Several similar known mutant genes for strabismus and amblyopia were also identified. In conclusion,natural strabismus and amblyopia are accompanied by abnormal asymmetries of the visual system,especially visual neurophysiological and neurostructural defects. Our results suggest that future therapeutic and mechanistic studies should consider defects and asymmetries throughout the entire visual system.展开更多

Methods: Preoperative patients (aged 6~12 years) were divided into two study groups: the topical aneasthesia group (n=22), and the general aneasthesia group (n=21). The study groups were compared on the following measures:.analgesic effect, surgical correction effect, eye-heart reflex, preoperative preparation time. and operation time, using t-tests or X2 tests where appropriate. Results:.Compared with the general aneasthesia group, the topical aneasthesia group gained better surgical correction results(P<0.05), had a lower rate of eye-heart reflex (P<0.05), and had a shorter preoperative preparation time (P<0.001). No significant difference was observed between the groups in terms of the analgesic effect or operation time (P>0.05). Conclusion:Topical aneasthesia represents a safe and effective alternative to general aneasthesia for strabismus surgery in children.展开更多

Case Report: Tight extraocular muscles during strabismus surgery could be extremely challenging even in experienced hands due to restricted globe rotation, limited view, and lack of muscle elasticity. Although a variety of surgical instruments have been introduced through the years, traditional muscle hooks such as the Jameson hook are largely unchanged and are bulky and cumbersome. Using the traditional muscle hook under situations such as pediatric strabismus surgery with smaller eyes and extraocular muscles may increase the risk of perforating the globe or even rupturing the muscles. We developed the “Suh muscle hook”, which has a 0.55 mm wide grooved track in a 1.1 mm wide horizontal bar, a semi-sharp dissecting tip, and a 30-degree bending near the handle accommodating for nasal bridge to better facilitate surgeons dealing with tight extraocular muscles and minimize risks during strabismus surgery.展开更多

文摘The design and efficacy of surgery for horizontal idiopathic nystagmus (HIN) with abnormal head posture and strabismus were investigated. Different surgical procedures were selected according to the angle of head turn in 44 cases of HIN with abnormal head posture and strabismus. For patients with a head turn of 15° or less, the Anderson procedure was used; the yoke muscles were recessed upon slow-phase. For patients with a head turn between 15° and 25°, the surgery was designed as a Kestenbaum 5-4-4-5 procedure. For patients with a head turn of 25° or more, the surgery was designed as a Parks 5-8-6-7 procedure. The surgery to correct the abnormal head posture was performed on the fixating eye while that to correct the deviation was then performed on the non-fixating eye at the same time. The amount of surgery of the horizontal rectus muscles on the nonfixating eye was sum of the angle of head turn and the degree of deviation, which was calculated as follows: recession/resection amount of medial and lateral rectis/2×5=angle of head turn±degree of deviation. The results showed as follows: (1) Visual acuity: the visual acuity in the primary ocular position increased two lines or more in 35 patients, accounting for 79.55%. Nine patients had no or only one-line improvement, accounting for 20.45% of the entire study population; (2) The degree of deviation in the primary ocular position: 37 cases had a normal primary ocular position or the degree of deviation ≤8△ after surgery, accounting for 84.09%. Six patients had a residual degree of deviation of 8△―15△, accounting for 13.64%. One patient had a residual degree of deviation 〉20△, accounting for 2.27% of the patients examined; (3) Abnormal head posture: 34 patients had a normal head posture or a head turn of less than 5°, accounting for 72.27%. Eight patients had a residual head turn of 5°―15°, accounting for 18.18%. Two patients had a head turn of 15°― 25°, accounting for 4.55%. It was concluded that different surgical procedures based on the angle of head turn and the relationship between deviation and null zone can eliminate anomalous head posture, correct deviation, and improve vision acuity in the primary ocular position simultaneously.

文摘AIM: To quantitatively investigate the retinal vascular diameter changes, analyzing the early and long-term effects on the retinal circulation, with 6-month follow-up. METHODS: Patients underwent horizontal strabismus surger y were enrolled prospectively. Retinal vessel diameters on color fundus photographs were assessed before and 1, 7 d, 6 mo after surgery, using a computerassisted quantitative assessment software. To evaluate the retinal vascular caliber changes, retinal vascular diameters were calculated by means of the Parr–Hubbard formula as the central retinal arteriolar equivalent(CRAE) and central retinal venular equivalent(CRVE). The arteriovenous ratio(AVR) was calculated as CRAE divided by CRVE. RESULTS: A total of 154 eyes of 104 consecutive patients were included. Compared with the data before surgery(121.55±24.67), the mean CRAE(131.18±28.29) significantly increased 1 d af ter surger y(P=0.003), but went back to baseline level at 7 d(118.89±30.35, P=0.15), and 6 mo(123.22±15.32, P=0.60), so did the AVR(P<0.001, P=0.08, P=0.07). As for the mean CRVE, there was no significant difference between those four time points(172.43±33.25, 175.57±36.98, 174.03±40.18, 174.86±20.46, P=1.00). CONCLUSION: Strabismus surgery on both lateral and media rectus muscles, or single media rectus muscle may increase retinal blood flow during the early postoperative period, but would return to normal later. The number of transected anterior ciliary arteries rather might be the main cause of retinal hemodynamic changes early after strabismus surgery.

文摘Dear Editor,cleral penetration during strabismus surgery was k3 first reported over 50 years ago[1].Early manuscripts reported the incidence of this complication around 10%[1].However,more recent studies suggest that this rate may have decreased[2-3].
文摘Anterior segment optical coherence tomography (AS-OCT) finds very few indications in the domain of strabismus surgery. Current applications remain restricted to determining limbus-muscle insertion distance and anterior segment changes after strabismus surgery. We discuss two cases of operated strabismus surgery where AS-OCT imaging helped in identifying the operated eye and/or extra ocular muscles (EOM) and thus proved instrumental in planning and management.

文摘Strabismus and amblyopia are common ophthalmologic developmental diseases caused by abnormal visual experiences. However, the underlying pathogenesis and visual defects are still not fully understood. Most studies have used experimental interference to establish diseaseassociated animal models, while ignoring the natural pathophysiological mechanisms. This study was designed to investigate whether natural strabismus and amblyopia are associated with abnormal neurological defects. We screened one natural strabismic monkey(Macaca fascicularis) and one natural amblyopic monkey from hundreds of monkeys, and retrospectively analyzed one human strabismus case. Neuroimaging, behavioral,neurophysiological, neurostructural, and genovariation features were systematically evaluated using magnetic resonance imaging(MRI), behavioral tasks, flash visual evoked potentials(FVEP),electroretinogram(ERG), optical coherence tomography(OCT), and whole-genome sequencing(WGS), respectively. Results showed that the strabismic patient and natural strabismic and amblyopic monkeys exhibited similar abnormal asymmetries in brain structure, i.e., ipsilateral impaired right hemisphere. Visual behavior, visual function, retinal structure, and fundus of the monkeys were impaired. Aberrant asymmetry in binocular visual function and structure between the strabismic and amblyopic monkeys was closely related, with greater impairment of the left visual pathway.Several similar known mutant genes for strabismus and amblyopia were also identified. In conclusion,natural strabismus and amblyopia are accompanied by abnormal asymmetries of the visual system,especially visual neurophysiological and neurostructural defects. Our results suggest that future therapeutic and mechanistic studies should consider defects and asymmetries throughout the entire visual system.
文摘Purpose:Comparison of topical vs general aneasthesia for strabismus surgery. Methods: Preoperative patients (aged 6~12 years) were divided into two study groups: the topical aneasthesia group (n=22), and the general aneasthesia group (n=21). The study groups were compared on the following measures:.analgesic effect, surgical correction effect, eye-heart reflex, preoperative preparation time. and operation time, using t-tests or X2 tests where appropriate. Results:.Compared with the general aneasthesia group, the topical aneasthesia group gained better surgical correction results(P<0.05), had a lower rate of eye-heart reflex (P<0.05), and had a shorter preoperative preparation time (P<0.001). No significant difference was observed between the groups in terms of the analgesic effect or operation time (P>0.05). Conclusion:Topical aneasthesia represents a safe and effective alternative to general aneasthesia for strabismus surgery in children.

文摘BACKGROUND This study was designed to investigate the clinical outcomes of enhanced recovery after surgery(ERAS)in the perioperative period in elderly patients with nonsmall cell lung cancer(NSCLC).AIM To investigate the potential enhancement of video-assisted thoracic surgery(VATS)in postoperative recovery in elderly patients with NSCLC.METHODS We retrospectively analysed the clinical data of 85 elderly NSCLC patients who underwent ERAS(the ERAS group)and 327 elderly NSCLC patients who received routine care(the control group)after VATS at the Department of Thoracic Surgery of Peking University Shenzhen Hospital between May 2015 and April 2017.After propensity score matching of baseline data,we analysed the postoperative stay,total hospital expenses,postoperative 48-h pain score,and postoperative complication rate for the 2 groups of patients who underwent lobectomy or sublobar resection.RESULTS After propensity score matching,ERAS significantly reduced the postoperative hospital stay(6.96±4.16 vs 8.48±4.18 d,P=0.001)and total hospital expenses(48875.27±18437.5 vs 55497.64±21168.63 CNY,P=0.014)and improved the satisfaction score(79.8±7.55 vs 77.35±7.72,P=0.029)relative to those for routine care.No significant between-group difference was observed in postoperative 48-h pain score(4.68±1.69 vs 5.28±2.1,P=0.090)or postoperative complication rate(21.2%vs 27.1%,P=0.371).Subgroup analysis showed that ERAS significantly reduced the postoperative hospital stay and total hospital expenses and increased the satisfaction score of patients who underwent lobectomy but not of patients who underwent sublobar resection.CONCLUSION ERAS effectively reduced the postoperative hospital stay and total hospital expenses and improved the satisfaction score in the perioperative period for elderly NSCLC patients who underwent lobectomy but not for patients who underwent sublobar resection.
文摘Purpose:To investigate the effect of proparacaine hydrochloride eye drops on emergence agitation after general anaesthesia for paediatric strabismus surgery.Methods:Paediatric patients(3-12 years-old)receiving strabismus surgery were randomly assigned to receive 1-2 drops of isotonic saline(n=129)or proparacaine hydrochloride(n=129)after surgery.The incidence and degree of emergence agitation were recorded and compared between groups.Results:A significantly lower occurrence of emergence agitation was observed with proparacaine hydrochloride drops compared to isotonic saline(12.4% vs.31.8%;p<0.05).Conclusion:Proparacaine hydrochloride eye drops reduce the incidence of emergence agitation after general anaesthesia for paediatric strabismus surgery.
文摘Purpose: To investigate the effect of diplopia on the daily life of patients after strabismus surgery and to explore appropriate nursing care measures.Methods:.A total of 200 patients who developed postoperative diplopia underwent telephone follow-up to evaluate the influence of diplopia on their daily lives..SPSS 19.0 statistical software was utilized for data analysis.Results: Postoperative diplopia affected patients' physical activity(49%), attention(39.2%), work and study(24.5%),emotions.(19.5%),.and housework performance.(17%),whereas it did not influence the quality of sleep. Potential risk factors associated with diplopia, such as duration of diplopia,gender, and age, were analyzed by uni- and multivariate regression analysis. Quality of life was significantly and negatively correlated with the duration of diplopia, but not correlated with gender or age.Conclusion:.Postoperative diplopia affects the quality of life in partial patients..The nursing staff should provide nursing care, health education, and explicit instructions to the patients after discharge. In addition, nursing care should be sustained by subsequent telephone follow-up.
文摘Purpose:To study corneal topographical changes after strabismus surgery.Methods:Computer-aided corneal topography was used in 43 strabismus patients(45 eyes)one or two days prior to and six or seven ays after strabismus surgery.The spherical and cylindrical equivalents were calculated based on the simulated keratometry.Results:After the surgery,only the changes at 3mm in the inferior quadrant were statistically significant.The changes at 3mm in the rest quadrants and the changes at 7mm were no significant.Significant changes in spherical equivalent were found post-operatively.neither the horizontal nor the verical meridional equivalent showed significant changes after surgery.Conclusions:The results of corneal topographical changes following strabismus surgery in our preliminary study indicated the little effect of strabismus surgery on corneal curvature and corneal astigmatism.

文摘BACKGROUND Colorectal cancer is a major global health challenge that predominantly affects older people.Surgical management,despite advancements,requires careful consideration of preoperative patient status for optimal outcomes.AIM To summarize existing evidence on the association of frailty with short-term postoperative outcomes in patients undergoing colorectal cancer surgery.METHODS A literature search was conducted using PubMed,EMBASE and Scopus databases for observational studies in adult patients aged≥18 years undergoing planned or elective colorectal surgery for primary carcinoma and/or secondary metastasis.Only studies that conducted frailty assessment using recognized frailty assess-ment tools and had a comparator group,comprising nonfrail patients,were included.Pooled effect sizes were reported as weighted mean difference or relative risk(RR)with 95%confidence intervals(CIs).RESULTS A total of 24 studies were included.Compared with nonfrail patients,frailty was associated with an increased risk of mortality at 30 d(RR:1.99,95%CI:1.47-2.69),at 90 d(RR:4.76,95%CI:1.56-14.6)and at 1 year(RR:5.73,95%CI:2.74-12.0)of follow up.Frail patients had an increased risk of any complications(RR:1.81,95%CI:1.57-2.10)as well as major complications(Clavien-Dindo classification grade≥III)(RR:2.87,95%CI:1.65-4.99)compared with the control group.The risk of reoperation(RR:1.18,95%CI:1.07-1.31),readmission(RR:1.70,95%CI:1.36-2.12),need for blood transfusion(RR:1.67,95%CI:1.52-1.85),wound complications(RR:1.49,95%CI:1.11-1.99),delirium(RR:4.60,95%CI:2.31-9.16),risk of prolonged hospitalization(RR:2.09,95%CI:1.22-3.60)and discharge to a skilled nursing facility or rehabilitation center(RR:3.19,95%CI:2.0-5.08)was all higher in frail patients.CONCLUSION Frailty in colorectal cancer surgery patients was associated with more complications,longer hospital stays,higher reoperation risk,and increased mortality.Integrating frailty assessment appears crucial for tailored surgical management.
文摘BACKGROUND Tourniquets are commonly used in elective extremity orthopaedic surgery to reduce blood loss,improve visualization in the surgical field,and to potentially reduce surgical time.There is a lack of consensus in existing guidelines regarding the optimal tourniquet pressure,placement site,and duration of use.There is a paucity of data on the relationship between the site of a tourniquet and postoperative pain in foot and ankle surgery.AIM To explore the relationship between tourniquet site and intensity of post-operative pain scores in patients undergoing elective foot and ankle surgery.METHODS Retrospective analysis of prospectively collected data on 201 patients who underwent foot and ankle surgery in a single institution was undertaken.Intraoperative tourniquet duration,tourniquet pressure and site,and postoperative pain scores using Visual Analogue Score were collected in immediate recovery,at six hours and at 24 h post-op.Scatter plots were used to analyse the data and to assess for the statistical correlation between tourniquet pressure,duration,site,and pain scores using Pearson correlation coefficient.RESULTS All patients who underwent foot and ankle surgery had tourniquet pressure of 250 mmHg for ankle tourniquet and 300 mmHg for thigh.There was no correlation between the site of the tourniquet and pain scores in recovery,at six hours and after 24 h.There was a weak correlation between tourniquet time and Visual Analogue Score immediately post-op(r=0.14,P=0.04)but not at six or 24 h post-operatively.CONCLUSION This study shows that there was no statistically significant correlation between tourniquet pressure,site and postop pain in patients undergoing foot and ankle surgery.The choice of using a tourniquet is based on the surgeon's preference,with the goal of minimizing the duration of its application at the operative site.

文摘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.

文摘Objectives Robotic-assisted surgery(RAS)is a minimally invasive technique practiced in multiple specialties.Standard training is essential for the acquisition of RAS skills.The cost of RAS is considered to be high,which makes it a burden for institutes and unaffordable for patients.This systematic literature review(SLR)focused on the various RAS training methods applied in different surgical specialties,as well as the cost elements of RAS,and was to summarize the opportunities and challenges associated with scaling up RAS.Methods An SLR was carried out based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses reporting guidelines.The PubMed,EBSCO,and Scopus databases were searched for reports from January 2018 through January 2024.Full-text reviews and research articles in the English language from Asia-Pacific countries were included.Articles that outlined training and costs associated with RAS were chosen.Results The most common training system is the da Vinci system.The simulation technique,which includes dry-lab,wet-lab,and virtual reality training,was found to be a common and important practice.The cost of RAS encompasses the installation and maintenance costs of the robotic system,the operation theatre rent,personnel cost,surgical instrument and material cost,and other miscellaneous charges.The synthesis of SLR revealed the challenges and opportunities regarding RAS training and cost.Conclusions The results of this SLR will help stakeholders such as decision-makers,influencers,and end users of RAS to understand the significance of training and cost in scaling up RAS from a managerial perspective.For any healthcare innovation to reach a vast population,cost-effectiveness and standard training are crucial.
文摘Purpose: To introduce an advanced muscle hook to decrease risks and create more feasible extraocular muscle surgeries for physicians. Case Report: Tight extraocular muscles during strabismus surgery could be extremely challenging even in experienced hands due to restricted globe rotation, limited view, and lack of muscle elasticity. Although a variety of surgical instruments have been introduced through the years, traditional muscle hooks such as the Jameson hook are largely unchanged and are bulky and cumbersome. Using the traditional muscle hook under situations such as pediatric strabismus surgery with smaller eyes and extraocular muscles may increase the risk of perforating the globe or even rupturing the muscles. We developed the “Suh muscle hook”, which has a 0.55 mm wide grooved track in a 1.1 mm wide horizontal bar, a semi-sharp dissecting tip, and a 30-degree bending near the handle accommodating for nasal bridge to better facilitate surgeons dealing with tight extraocular muscles and minimize risks during strabismus surgery.
文摘AIM:To evaluate ocular alignment and surgical results of strabismus surgery in neurologically impaired children.· METHODS:Files of 33 neurologically impaired squint children were evaluated.Twelve patients had cerebral palsy(CP),4 had CP with mental retardation,therest had mental-motor retardation of unknown cause.Cycloplegic refractions,type and angle of strabismus,surgeries performed were recorded.· RESULTS:Mean follow-up was 34.0±16.5 months.Twenty-three patients had esodeviation,the remaining had exodeviation.In 19 patients,angle of deviations measured at different visits were highly variable.Twelve patients with stable angle of deviations or with unstable but high angle deviations had horizontal muscle surgery.Mean horizontal deviation decreased from 43.75±10,69 D to 12.83±8.38D with surgery.· CONCLUSION:In neurologically impaired strabismic children,surgery is effective in patients with stable deviations or unstable but high angle deviations.Decision for surgery should be made after a long follow up period.
文摘In this editorial we comment on the article by Kalayarasan and co-workers published in the recent issue of the World Journal of Gastrointestinal Surgery.The authors present an interesting review on the use of indocyanine green fluo-rescence in different aspects of abdominal surgery.They also highlight future perspectives of the use of indocyanine green in mini-invasive surgery.Indo-cyanine green,used for fluorescence imaging,has been approved by the Food and Drug Administration and is safe for use in humans.It can be administered in-travenously or intra-arterially.Since its advent,there have been several advance-ments in the applications of indocyanine green,especially in the surgical field,such as intraoperative mapping and biopsy of sentinel lymph node,measurement of hepatic function prior to resection,in neurosurgical cases to detect vascular anomalies,in cardiovascular cases for patency and assessment of vascular ab-normalities,in predicting healing following amputations,in helping visualization of hepatobiliary anatomy and blood vessels,in reconstructive surgery,to assess flap viability and for the evaluation of tissue perfusion following major trauma and burns.For these reasons,the intraoperative use of indocyanine green has become common in a variety of surgical specialties and transplant surgery.Co-lorectal surgery has just lately begun to adopt this technique,particularly for perfusion visualization to prevent anastomotic leakage.The regular use of in-docyanine green coupled with fluorescence angiography has recently been pro-posed as a feasible tool to help improve patient outcomes.Using the best available data,it has been shown that routine use of indocyanine green in colorectal surgery reduces the rates of anastomotic leak.The use of indocyanine green is proven to be safe,feasible,and effective in both elective and emergency scenarios.However,additional robust evidence from larger-scale,high-quality studies is essential before incorporating indocyanine green guided surgery into standard practice.
