Sutton PA, van Dam MA, Cahill RA, Mieog S, Polom K, Vahrmeijer AL, van der Vorst J. Fluorescence-guided surgery: comprehensive review. BJS Open 2023; 7:7162090. [PMID: 37183598 PMCID: PMC10183714 DOI: 10.1093/bjsopen/zrad049] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 04/02/2023] [Accepted: 04/03/2023] [Indexed: 05/16/2023] Open
Abstract
BACKGROUND Despite significant improvements in preoperative workup and surgical planning, surgeons often rely on their eyes and hands during surgery. Although this can be sufficient in some patients, intraoperative guidance is highly desirable. Near-infrared fluorescence has been advocated as a potential technique to guide surgeons during surgery. METHODS A literature search was conducted to identify relevant articles for fluorescence-guided surgery. The literature search was performed using Medical Subject Headings on PubMed for articles in English until November 2022 and a narrative review undertaken. RESULTS The use of invisible light, enabling real-time imaging, superior penetration depth, and the possibility to use targeted imaging agents, makes this optical imaging technique increasingly popular. Four main indications are described in this review: tissue perfusion, lymph node assessment, anatomy of vital structures, and tumour tissue imaging. Furthermore, this review provides an overview of future opportunities in the field of fluorescence-guided surgery. CONCLUSION Fluorescence-guided surgery has proven to be a widely innovative technique applicable in many fields of surgery. The potential indications for its use are diverse and can be combined. The big challenge for the future will be in bringing experimental fluorophores and conjugates through trials and into clinical practice, as well as validation of computer visualization with large data sets. This will require collaborative surgical groups focusing on utility, efficacy, and outcomes for these techniques.

Persistent acute cholecystitis after cholecystostomy - increased mortality due to treatment approach? HPB (Oxford) 2022; 24:963-973. [PMID: 34865990 DOI: 10.1016/j.hpb.2021.11.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 11/02/2021] [Accepted: 11/07/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND Percutaneous cholecystostomy (PC) is a treatment option for acute cholecystitis (AC) in cases where cholecystectomy (CCY) is not feasible due to limited health conditions. The use of PC remains questionable. The aim was to retrospectively analyse the outcome of patients after PC. METHODS All patients who underwent PC for AC at a tertiary referral hospital over 10 years were included. Descriptive statistics, analysed mortality with and without CCY after PC, and a multivariable logistic regression for potential confounder and a landmark sensitivity analysis for immortal time bias were used. RESULTS Of 158 patients, 79 were treated with PC alone and 79 had PC with subsequent CCY. Without CCY, 48% (38 patients) died compared to 9% with CCY. In the multivariable analysis CCY was associated with 85% lower risk of mortality. The landmark analysis was compatible with the main analyses. Direct PC-complications occurred in 17% patients. Histologically, 22/75 (29%) specimens showed chronic cholecystitis, and 76% AC. CONCLUSION Due to the high mortality rate of PC alone, performing up-front CCY is proposed. PC represents no definitive treatment for AC and should remain a short-term solution because of the persistent inflammatory focus. According to these findings, almost all specimens showed persistent inflammation.

Conversion from laparoscopic to open cholecystectomy: Risk factor analysis based on clinical, laboratory, and ultrasound parameters. REVISTA DE GASTROENTEROLOGÍA DE MÉXICO 2021; 86:363-369. [PMID: 34384723 DOI: 10.1016/j.rgmxen.2021.08.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Accepted: 07/19/2020] [Indexed: 12/24/2022]
Abstract
INTRODUCTION AND AIMS The standard of care for gallbladder disease is laparoscopic cholecystectomy. Difficult dissection of the hepatocytic triangle and bleeding can result in conversion to open cholecystectomy, which is associated with increased morbidity. Identifying risk factors for conversion in the context of acute cholecystitis will allow patient care to be individualized and improve outcomes. MATERIALS AND METHODS A retrospective case-control study included all patients diagnosed with acute cholecystitis, according to the 2018 Tokyo Guidelines, admitted to a tertiary care academic center, from January 1991 to January 2012. Using logistic regression, we analyzed variables to identify risk factors for conversion. Variables that were found to be significant predictors of conversion in the univariate analysis were included in a multivariate model. We then performed an exploratory analysis to identify the risk factor summation pathway with the highest sensitivity for conversion. RESULTS The study included 321 patients with acute cholecystitis. Their mean age was 49 years (±16.8 SD), 65% were females, and 35% were males. Thirty-nine cases (12.14%) were converted to open surgery. In the univariate analysis, older age, male sex, gallbladder wall thickness, and pericholecystic fluid were associated with a higher risk for conversion. In the multivariate analysis all of the variables, except pericholecystic fluid, were associated with conversion. Our risk factor summation model had a sensitivity of 84%. CONCLUSIONS Preoperative clinical data can be utilized to identify patients with a higher risk of conversion to open cholecystectomy. Being aware of such risk factors can help improve perioperative planning and preparedness in challenging cases.

Evaluation of the conversion rate as it relates to preoperative risk factors and surgeon experience: a retrospective study of 4013 patients undergoing elective laparoscopic cholecystectomy. BMC Surg 2021; 21:151.

Abstract
Background Our aim is to determine the relationships among patient demographics, patient history, surgical experience, and conversion rate (CR) during elective laparoscopic cholecystectomies (LCs). Methods We analyzed data from patients who underwent LC surgery between 2005 and 2014 based on patient charts and electronic documentation. CR (%) was evaluated in 4013 patients who underwent elective LC surgery. The relationships between certain predictive factors (patient demographics, endoscopic retrograde cholangiopancreatography (ERCP), acute cholecystitis (AC), abdominal surgery in the patient history, as well as surgical experience) and CR were examined by univariate analysis and logistic regression. Results In our sample (N = 4013), the CR was 4.2%. The CR was twice as frequent among males than among females (6.8 vs. 3.2%, p < 0.001), and the chance of conversion increased from 3.4 to 5.9% in patients older than 65 years. The detected CR was 8.8% in a group of patients who underwent previous ERCP (8.8 vs. 3.5%, p < 0.001). From the ERCP indications, most often, conversion was performed because of severe biliary tract obstruction (CR: 9.3%). LC had to be converted to open surgery after upper and lower abdominal surgeries in 18.8 and 4.8% cases, respectively. Both AC and ERCP in the patient history raised the CR (12.3%, p < 0.001 and 8.8%, p < 0.001). More surgical experience and high surgery volume were not associated with a lower CR prevalence. Conclusions Patient demographics (male gender and age > 65 years), previous ERCP, and upper abdominal surgery or history of AC affected the likelihood of conversion. More surgical experience and high surgery volume were not associated with a lower CR prevalence.

Does near-infrared fluorescent cholangiography with indocyanine green reduce bile duct injuries and conversions to open surgery during laparoscopic or robotic cholecystectomy? - A meta-analysis. Surgery 2021; 169:859-867. [PMID: 33478756 DOI: 10.1016/j.surg.2020.12.008] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 11/10/2020] [Accepted: 12/07/2020] [Indexed: 12/20/2022]
Abstract
BACKGROUND Bile duct injury and conversion-to-open-surgery rates remain unacceptably high during laparoscopic and robotic cholecystectomy. In a recently published randomized clinical trial, using near-infrared fluorescent cholangiography with indocyanine green intraoperatively markedly enhanced biliary-structure visualization. Our systematic literature review compares bile duct injury and conversion-to-open-surgery rates in patients undergoing laparoscopic or robotic cholecystectomy with versus without near-infrared fluorescent cholangiography. METHODS A thorough PubMed search was conducted to identify randomized clinical trials and nonrandomized clinical trials with ≥100 patients. Because all near-infrared fluorescent cholangiography studies were published since 2013, only studies without near-infrared fluorescent cholangiography published since 2013 were included for comparison. Incidence estimates, weighted and unweighted for study size, were adjusted for acute versus chronic cholecystitis, and for robotic versus laparoscopic cholecystectomy and are reported as events/10,000 patients. All studies were assessed for bias risk and high-risk studies excluded. RESULTS In total, 4,990 abstracts were reviewed, identifying 5 near-infrared fluorescent cholangiography studies (3 laparoscopic cholecystectomy/2 robotic cholecystectomy; n = 1,603) and 11 not near-infrared fluorescent cholangiography studies (5 laparoscopic cholecystectomy/4 robotic cholecystectomy/2 both; n = 5,070) for analysis. Overall weighted rates for bile duct injury and conversion were 6 and 16/10,000 in near-infrared fluorescent cholangiography patients versus 25 and 271/10,000 in patients without near-infrared fluorescent cholangiography. Among patients undergoing laparoscopic cholecystectomy, bile duct injuries, and conversion rates among near-infrared fluorescent cholangiography versus patients without near-infrared fluorescent cholangiography were 0 and 23/10,000 versus 32 and 255/10,000, respectively. Bile duct injury rates were low with robotic cholecystectomy with and without near-infrared fluorescent cholangiography (12 and 8/10,000), but there was a marked reduction in conversions with near-infrared fluorescent cholangiography (12 vs 322/10,000). CONCLUSION Although large comparative trials remain necessary, preliminary analysis suggests that using near-infrared fluorescent cholangiography with indocyanine green intraoperatively sizably decreases bile duct injury and conversion-to-open-surgery rates relative to cholecystectomy under white light alone.

Abstract
BACKGROUND Consistent measurement and reporting of outcomes, including adequately defined complications, is important for the evaluation of surgical care and the appraisal of new surgical techniques. The range of complications reported after LC has not been evaluated. This study aimed to identify the range of complications currently reported for laparoscopic cholecystectomy (LC), and the adequacy of their definitions. METHODS MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched for prospective studies reporting clinical outcomes of LC, between 2013 and 2016. RESULTS In total 233 studies were included, reporting 967 complications, of which 204 (21%) were defined. One hundred and twenty-two studies (52%) did not provide definitions for any of the complications reported. Conversion to open cholecystectomy was the most commonly reported complication, reported in 135 (58%) studies, followed by bile leak in 89 (38%) and bile duct injury in 75 (32%). Mortality was reported in 89 studies (38%). CONCLUSION Considerable variation was identified between studies in the choice of measures used to evaluate the complications of LC, and in their definitions. A standardised set of core outcomes of LC should be developed for use in clinical trials and in evaluating the performance of surgical units.

Abstract
BACKGROUND Minimally invasive surgery is associated with several patient-related benefits, including reduced length of hospital stay and reduced blood loss. Robotic-assisted surgery offers many advantages when compared with standard laparoscopic procedures, including a stable three-dimensional binocular camera platform, motion smoothing and motion scaling, improved dexterity and ergonomics. There are limited data on the effectiveness of the dual-console DaVinci Xi platform for teaching resident surgeons. The goal of this study was to examine preliminary outcomes following the introduction of a dual-console robotic platform in our institution. METHODS A retrospective review of our prospectively maintained patient database was performed. The first ten dual-console resident-performed procedures in colorectal surgery were compared with matched cases performed on a single console by the trainer. Patient demographics, operative times and patient outcomes were compared. RESULTS Twenty patients were included in this study. There was no significant difference in console time (p = 0.46) or total operative time (p = 0.52) when residents and trainers were compared. Patient outcomes were equivalent, with no difference in length of stay, morbidity or mortality. CONCLUSIONS The DaVinci Xi dual-console platform is a safe and effective platform for training junior surgeons. The dual-console system has the potential to alter surgical training pathways.
