BACKGROUND: Additional surgery is necessary in cases with non-curative endoscopic submucosal dissection. It is still unknown whether preceding endoscopic submucosal dissection (ESD) for T1 colorectal carcinoma affects the short outcomes of patients who underwent additional surgery or not as compared with surgery alone without ESD. METHODS: Patients (101 pairs) with T1 colorectal cancer who underwent additional laparoscopic-assisted surgery after endoscopic submucosal dissection (additional surgery group, n = 101) or laparoscopic-assisted surgery alone (surgery alone group, n = 101) were matched (1:1). Short-term morbidity, operation outcomes, and lymph node metastasis of the resected specimen were compared. RESULTS: There were no significant differences between the additional laparoscopic-assisted surgery and laparoscopic-assisted surgery alone groups in lymph node metastasis (9.9 vs. 5.9%, respectively, p = 0.297), operative time (147.76 ± 52.00 min vs. 156.50 ± 54.28 min, p = 0.205), first flatus time (3.56 ± 1.10 days vs. 3.63 ± 1.05 days, p = 0.282), first stool time (4.30 ± 1.04 days vs. 4.39 ± 1.22 days, p = 0.293), time to intake (5.00 ± 1.18 days vs. 5.25 ± 1.39 days, p = 0.079), blood loss (44.75 ± 45.40 mL vs. 60.40 ± 78.98 mL, p = 0.603), harvest lymph nodes (18.74 ± 7.22 vs. 20.32 ± 9.69, p = 0.438), postoperative surgical complications (p = 0.733), and postoperative length of hospital stay (8.68 ± 4.00 days vs. 8.39 ± 1.94 days, p = 0.401). CONCLUSION: ESD did not increase the difficulty of additional laparoscopic-assisted surgery, hospital stay, or the incidence of postoperative complications. Additional laparoscopic-assisted surgery is safe and recommended for patients with T1 cancer at high risk of lymph node metastasis and residual cancer after non-curative ESD.

INTRODUCTION: Colorectal cancer (CRC) is the fourth leading cause of death with 1.4 million new cases occurring annually worldwide. High-quality clinical practice guidelines are needed to tailor high-quality individualized treatment. The aim of the present study was to evaluate the methodological quality of the current guidelines for the management of acute malignant left-sided colonic bowel obstruction. METHODS: A systematic search of the literature was carried out using electronic databases. The Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument was used to assess the quality of each guideline. RESULTS: Search results returned a total of 14 guidelines appropriate for assessment. Both domain I (scope and purpose) and domain VI (editorial independence) were assessed with the same median score of 83%. The lowest scoring domain was domain V (applicability), scoring only 43%. The 2 guidelines that had the highest score were the National Institute for Health and Care Excellence (NICE) and Scottish Intercollegiate Guidelines Network (SIGN), each scoring 100%. However, there were significant variations in terms of quality. The NICE and New Zealand guidelines were voted unanimously for use unchanged, whilst 8 other guidelines were voted for use with modifications. CONCLUSION: Variation in guideline quality in CRC is a concern despite some clearly excellent published guidelines. All guidelines score poorly when it comes to describing how the guidelines could be applied. Lack of patient participation in guideline development is also a shortcoming that requires urgent redress.

INTRODUCTION: Recently, "low-grade appendiceal mucinous neoplasms" (LAMNs) have been proposed as one subtype of appendiceal mucinous neoplasms, characterized by a villous or flat proliferation of mucinous epithelium with low-grade cytologic atypia. The aim of this study was to clarify the clinicopathological characteristics of LAMN. METHODS: In this multi-institutional cohort study, we retrospectively analyzed the clinicopathological characteristics in appendiceal neoplasms patients who underwent treatment from 2000 to 2017. RESULTS: In total, 922 patients were enrolled, with 279 (30.3%) cases of LAMN, and 93 (10.1%) cases of non-LAMN disease. In comparison with patients with non-LAMN disease, those with LAMN had significantly lower levels of CA19-9 (p = 0.045), a lower frequency of T4 tumors (p < 0.0001), a lower frequency of lymph node metastasis (p < 0.0001), and a lower frequency of distant metastasis (p < 0.0001). Survival analysis revealed that patients with LAMN had a significantly better prognosis than did those with non-LAMN disease (p < 0.001). Among the patients with distant metastasis, those with LAMN had a significantly better prognosis than did those with non-LAMN disease (p = 0.0020), but among the patients without distant metastasis, the difference between the 2 groups was not significant (p = 0.26). However, among patients who underwent complete resection, the difference in prognosis between the 2 groups was not significant (p = 0.10). CONCLUSIONS: A multicenter retrospective study revealed that the clinicopathological characteristics of LAMN was different from those of non-LAMN.

INTRODUCTION: The peritoneal cancer index (PCI) is one of the most important prognostic factors in patients with peritoneal metastases from colorectal cancer undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). The PCI is determined during laparotomy by 2 experienced surgeons and plays a major role in the decision to proceed with CRS-HIPEC. The primary objective of this study was to determine the accuracy of the surgical PCI (sPCI) by comparing it with the PCI confirmed by the pathologist (pPCI). METHODS: All consecutive patients who underwent CRS-HIPEC for colorectal peritoneal metastases between February 2015 and June 2018 were identified. Relevant patient- and tumor-related characteristics were collected. RESULTS: In total, 119 patients were included, 60 males (50.4%). The median age was 64 (IQR 55-71). The median sPCI (sPCI = 11, IQR 6-16) was significantly higher than the median pPCI (pPCI = 8, IQR 3-13, p < 0.001). The total pPCI was lower than the total sPCI in 80 patients (67.2%). In 21 patients (17.6%), the sPCI was overestimated with ≥5 points. Small lesions are more likely to be negative. In patients that underwent resection of their primary tumor prior to CRS-HIPEC, the difference between the sPCI and pPCI was significantly larger (p < 0.05). CONCLUSIONS: Surgical calculation of the PCI often results in overestimation. Far-reaching consequences are tied to the macroscopic evaluation of the sPCI, but this evaluation seems not very reliable.

BACKGROUND: This survey aimed to register changes determined by the COVID-19 pandemic on pancreatic surgery in a specific geographic area (Germany, Austria, and Switzerland) to evaluate the impact of the pandemic and obtain interesting cues for the future. METHODS: An online survey was designed using Google Forms focusing on the local impact of the pandemic on pancreatic surgery. The survey was conducted at 2 different time points, during and after the lockdown. RESULTS: Twenty-five respondents (25/56) completed the survey. Many aspects of oncological care have been affected with restrictions and delays: staging, tumor board, treatment selection, postoperative course, adjuvant treatments, outpatient care, and follow-up. Overall, 60% of respondents have prioritized pancreatic cancer patients according to stage, age, and comorbidities, and 40% opted not to operate high-risk patients. However, for 96% of participants, the standards of care were guaranteed. DISCUSSION/CONCLUSIONS: The first wave of the COVID-19 pandemic had an important impact on pancreatic cancer surgery in central Europe. Guidelines for prompt interventions and prevention of the spread of viral infections in the surgical environment are needed to avoid a deterioration of care in cancer patients in the event of a second wave or a new pandemic. High-volume centers for pancreatic surgery should be preferred and their activity maintained. Virtual conferences have proven to be efficient during this pandemic and should be implemented in the near future.

BACKGROUND: Peroral endoscopic myotomy (POEM) has been reported to be effective in achalasia patients with prior failed endoscopic intervention (PFI). We performed this meta-analysis to compare and summarize the clinical outcome of POEM in patients with or without prior endoscopic intervention. METHOD: We searched relevant studies published up to March 2020. Meta-analysis for technical success, clinical success, Eckardt score, lower esophageal sphincter (LES) pressure, clinical reflux, and adverse event were conducted based on a random-effects model. RESULTS: Eight studies enrolling 1,797 patients who underwent POEM were enrolled, including 1,128 naïve achalasia patients and 669 patients with PFI. In the PFI group, the pooled estimated rate of technical success was 97.7% (95% confidence interval [CI], 95.8-98.8%), the pooled clinical success rate was 91.0% (95% CI, 88.0-93.4%), and the pooled adverse events rate was 23.5% (95% CI, 10.6-44.1%). The Eckardt score significantly decreased by 5.95 points (95% CI, 5.50-6.40, p < 0.00001) and the LES pressure significantly reduced by 19.74 mm Hg (95% CI, 14.10-25.39, p < 0.00001) in the PFI group. There were no difference in the technical success, clinical success, and adverse events rate between the treatment-naïve group and PFI group, with a risk ratio of 1.0 (95% CI, 0.99-1.01, p = 0.89), 1.02 (95% CI, 0.98-1.06, p = 0.36), and 0.88 (95% CI, 0.67-1.16, p = 0.38), respectively. CONCLUSIONS: POEM is an effective and safe treatment for achalasia patients with prior endoscopic intervention. Randomized clinical trials are needed to further verify the efficiency and safety of the POEM in those patients.

BACKGROUND: Postoperative complications after pancreatectomy are a challenging problem due to their high incidence and serious consequences. The majority of studies have focused on a specific complication, but data on predictors of overall postoperative complications (OPCs) are limited. METHODS: The data of patients who underwent pancreatectomy at a single institute between 2017 and 2019 were analyzed retrospectively. Univariate and multivariate logistic regression were used to investigate predictors of the outcomes of interest. The Clavien-Dindo classification and comprehensive complication index (CCI) were used to assess postoperative complications and the severity of postoperative complications. The relationship between predictors and the CCI was evaluated by linear regression. RESULTS: A total of 490 patients were divided into a training group (n = 339) and a validation group (n = 151). The rate of OPCs was 44.25%. Fluid transfusion and albumin difference (AD) were predictors of OPCs. AD showed a good discrimination (AUC = 0.70) and good calibration in the validation cohort. AD was associated with complications, including pancreatic fistula, intra-abdominal hemorrhage, intra-abdominal infection, delayed gastric emptying, and re-intervention, and was positively correlated with complication severity. Intraoperative blood loss and preoperative albumin were independent predictors of AD. CONCLUSIONS: AD, a variable that reflects dynamic physiological changes is a new and accessible predictor of OPCs following pancreatectomy.

INTRODUCTION: Tumor grade, one of the most important risk factors for survival, is routinely determined after examining the biopsy material or a surgically removed specimen. The aim of the study was to analyze computed tomography (CT) perfusion parameters and diffusion-weighted imaging apparent diffusion coefficient (ADC) values in pancreatic ductal adenocarcinoma (PDAC) and to establish the diagnostic value of these modalities determining the tumor grade. MATERIALS AND METHODS: A prospective clinical study included 56 subjects with PDAC. All the patients had a local perfusion assessment and ADC measurement of the tumor. For the prediction of poor tumor differentiation sensitivity, specificity, positive, and negative predictive values for each perfusion CT and ADC parameters based on cutoff values from ROC analysis were calculated. RESULTS: Mean transit time (MTT) and ADC values were found to be independent prognosticators for the presence of G3 PDAC. MTT and ADC at the cutoff of 17.37 s and 1.15 × 10-3 mm2/s, respectively, appeared to be significant parameters discriminating against the differentiation grade of PDAC. If both values exceeded the defined cutoff point, the estimated probability for the presence of G3 PDAC was 89.29%. CONCLUSION: The MTT parameter, calculated with the deconvolution method, and the ADC value may serve as effective independent prognosticators identifying poorly differentiated PDAC.

BACKGROUND AND OBJECTIVES: The goal of this study was to compare disease-specific risk factors and 30-day outcomes between patients with Crohn's disease (CD) and colon cancer (CC) undergoing right-sided surgical resection. METHODS: The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP®) was interrogated to extract all patients ≥18 years undergoing elective right-sided resection for CD versus CC. Independent risk factors for surgical complications were identified through multivariable logistic regression for both groups. In a second step, surgical and medical 30-day morbidity was compared after risk adjustment. RESULTS: The cohort consisted of 17,516 patients, of which 2,899 (16.6%) underwent surgery for CD versus 14,617 (83.4%) for CC. Independent risk factors for surgical complications in patients with CD were male gender, African American race, ASA score (III or IV), active smoking, prolonged surgery, and preoperative anemia. Independent risk factors for surgical complications in the cancer group were age ≥70 years, male gender, ASA score (III or IV), respiratory and cardiovascular comorbidities, and preoperative hypoalbuminemia (<3.5 g/dL). After risk adjustment, surgical complications (OR 1.25, p = 0.002), sepsis (OR 1.64, p = 0.012), and unplanned readmissions (OR 1.39, p = 0.004) were more common in patients with CD. Thirty-day mortality was higher in cancer patients (1.1 vs. 0.1%, p < 0.0001). CONCLUSIONS: Patients with Crohn's disease were more prone to surgical complications and postoperative sepsis compared to the cancer group undergoing the same procedure. Careful evaluation and correction of disease-specific modifiable risk factors of patients with CD and CC, respectively, are important.

BACKGROUND: Perianal fistula is a common colorectal condition with an incidence of 9 per 100,000. Many surgical treatments exist, all aiming to eliminate symptoms with minimal risk of recurrence and impact upon continence. Despite extensive evaluation of the therapeutic modalities, no clear consensus exists as to what is the gold standard approach. This systematic review aimed to examine all available evidence pertaining to the surgical management of perianal fistulas. Primary outcomes examined were recurrence and incontinence. SUMMARY: This study was conducted according to PRISMA guidelines. Primary outcomes were analyzed for each group and expressed as pooled odds ratio with confidence intervals of 95%. 687 studies were identified from which 28 relevant studies were included. There was no significant difference in rates of incontinence identified between various surgical approaches. Glues and plugs show higher recurrence rates. Newer treatments continue to emerge with promise but lack supporting evidence of benefit over conventional therapies. Key Messages: While we await more robust randomized data, we will continue to proceed cautiously trying to offset the benefits of fistula healing against the inherent risk of altered continence.

INTRODUCTION/OBJECTIVE: Acute mesenteric ischemia (AMI) is difficult to diagnose. Since the established parameters have low sensitivity and specificity, the aim of this study is to analyze the diagnostic quality of the established parameters of AMI. METHODS: All patients that underwent emergency surgery due to suspected diagnosis of mesenteric ischemia at the University Medical Center Hamburg-Eppendorf between 2008 and 2014 were evaluated. Overall, 275 patients were enrolled and pre-, intra- and postoperative data were evaluated. RESULTS: In 200 patients, a mesenteric ischemia was confirmed intraoperatively, and 75 patients had no ischemia. Comparing these groups, the rate of patients with pH < 7.2 (25 vs. 12%; p = 0.021) and elevated mean CRP level (175 ± 117 mg/L vs. 139 ± 104 mg/L; p = 0.019) was significantly higher in ischemic patients. There was no significant difference in the level of preoperative lactate. Concerning abdominal CT scan, a sensitivity and specificity of 61 and 68%, respectively, was found. CONCLUSION: New diagnostic parameters are needed. So far, explorative laparotomy is the only reliable diagnostic method to detect mesenteric infarction.

Biliary injuries during cholecystectomy represent serious adverse events that can have a profound impact on the patient's quality of life and on the surgeon's well-being and career. Sometimes, they can have an unexpectedly disastrous effect on the whole community, as demonstrated by the case of Anthony Eden, former foreign secretary and prime minister of Britain in the 1950s. Mr. Eden, later Lord Avon, had been suffering from biliary symptoms for a while when he had his cholecystectomy performed on April 12, 1953. On post-op day 1, a bile leak was evident, possibly due to a complete transection of the common bile duct. After a first reoperation to drain a bile collection, the definitive repair was performed in Boston by Dr. Cattell on June 10, 1953, with a loop hepatico-jejunostomy. Unfortunately, the bilioenteric anastomosis became gradually narrow, causing recurrent cholangitis, and Mr. Eden started a symptomatic treatment with pethidine, barbiturate, and amphetamine. These could have affected his perception of reality and his political judgement during the Suez Canal Crisis and, other than being the ultimate reason for 3,000+ war casualties, might have caused a Third World War. The historical and clinical implications of this case are thoroughly discussed.

BACKGROUND: The primary aim was to assess the diagnostic accuracy of routine ultrasound assessment for gallbladder polyps. The secondary aim was to identify the characteristics that differentiate neoplastic polyps from nonneoplastic polyps. METHODS: A total of 156 patients with histopathologically proven gallbladder polyps in 4 Dutch hospitals between 2003 and 2013 were included. Sensitivity and specificity of ultrasound for polyp size, number of polyps, and polyp type were assessed using histopathological findings as a reference standard. In addition, diagnostic accuracy of sonographic size ≥1 cm for neoplasia was assessed. Subgroup analysis for patients with polyps as primary indication for cholecystectomy was performed. The sonographic polyp characteristics on preoperative routine ultrasound were described. RESULTS: Fifty-six percent of gallbladder polyps were preoperatively identified on ultrasound, of which 31% were neoplastic. Sensitivity and specificity of ultrasound to estimate polyp size were 93 and 43% (subgroup; 92 and 33%). Sensitivity and specificity of sonographic polyp size ≥1 cm for neoplasia were 86 and 32% (subgroup; 94 and 26%). No specific sonographic characteristics for neoplastic polyps could be established due to lack of reporting. CONCLUSION: Routine ultrasound assessment of polyps is associated with overestimation of polyp size and low specificity of sonographic size ≥1 cm for neoplasia, which contributes to surgical overtreatment of nonneoplastic polyps.

INTRODUCTION: There is a dearth of literature on frailty specifically in elderly (aged ≥65 years) gastric cancer patients undergoing gastrectomy. We aim to assess the effects of frailty on postoperative outcomes. METHODS: A review of a prospective database was performed from November 2011 to April 2019. Frailty was assessed by multidimensional frailty score (MFS). Outcomes assessed were early postoperative complications and mortality, and length of stay. RESULTS: 289 patients were included. The mean age was 77.3 (range 66-94) years. 183 (63.3%) were males and 172 (59.5%) had early cancer. 275 (95.2%) underwent minimally invasive gastrectomy. 79 (27.3%) patients suffered early postoperative complications, with 47 (16.3%) suffering from Clavien-Dindo grade ≥2 complications. One-year, 90-day, 30-day, and inhospital mortality were 6.6, 1.4, 0.7, and 0%, respectively. 111 (38.4%) of patients were classified as "frail" based on MFS > 5. "Frail" patients were associated with higher 1-year mortality (odds ratio (OR) 4.51, 95% CI 1.57-12.98, p = 0.005) on univariate analysis. On multivariate analysis, "frail" patients did not have significantly increased 1-year mortality. However, when definition of "frail" was changed from MFS > 5 to MFS > 6, frailty was significantly associated with increased 1-year mortality (OR 3.73, 95% CI 1.11-12.53, p = 0.033). CONCLUSIONS: Elderly gastric cancer patients undergoing gastrectomy with MFS > 5 do not have increased mortality risk. The influence of frailty on postoperative outcomes may vary based on the risk of the surgical procedure.

BACKGROUNDS: Endoscopic submucosal dissection (ESD) has been widely performed in the treatment of early esophageal squamous cell carcinoma (ESCC). Few studies have compared the long-term outcomes of esophageal ESD based on absolute indications and relative indications. The aim of the current study was to investigate the safety and efficacy of ESD for early ESCC with relative indications. METHODS: 297 patients with early ESCC who underwent ESD were retrospectively analyzed. They were divided into 3 groups: group A, the absolute indications group; group B, the relative indications without additional treatment after ESD group; and group C, the relative indications with additional treatment after ESD group. The baseline characteristics, therapeutic efficacy, complications, prognosis outcomes, and follow-up data were evaluated. RESULTS: During the median follow-up period of 51.0 months (range 6-101 months), the incidence of local recurrence in groups A, B, and C was 1.63% (3/184), 4.23% (3/71), and 0 (0/42), respectively (p = 0.253). The 5-year overall survival rates were 97.83% (95% CI: 95.69-99.95%) in group A, 95.77% (95% CI: 90.95-100.00%) in group B, and 97.62% (95% CI: 92.81-100.00%) in group C with no significant differences among these 3 groups. CONCLUSIONS: ESD is a feasible and effective treatment for early ESCC with relative indications. Under the premise of sufficient preoperative assessment and scheduled postoperative endoscopic surveillance, additional treatment might not be necessary for patients with relative indications after ESD procedures.

BACKGROUND: Current guidance for type 1 gastric neuroendocrine neoplasms (gNENs) recommends either resection of all visible lesions or selective resection of gNENs >10 mm. We adopt a selective strategy targeting lesions approaching 10 mm for endoscopic mucosal resection (EMR) and provide surveillance for smaller lesions. OBJECTIVES: This study aimed to describe the incidence of type 1 gNENs requiring endoscopic/surgical resection and the risk of disease progression (both considered significant disease) on endoscopic surveillance. The secondary objective was to assess the risk factors for disease progression during surveillance and the incidence of gastric dysplasia/adenoma/adenocarcinoma. METHODS: We collected consecutive patients with type 1 gNENs and obtained demographic and clinical data through the electronic patient record. RESULTS: In our cohort of 57 patients, 12 patients had EMR at index gastroscopy; 7 patients had surgery (4: large/multiple gNENs and 3: nodal metastases) (5.2% [3/57] risk of nodal metastases); and a patient with nodal and liver metastases (1.8% [1/57] risk of distant metastases). The prevalence of gastric adenocarcinoma in our study was 3.5% with an incidence rate of 9.59 per 1,000 persons per year. For patients undergoing surveillance, 29.5% (13/44) of patients progressed requiring resection. Serum gastrin was significantly higher in patients who progressed to resection (p value = 0.023). CONCLUSION: We concluded that up to a third of patients with type 1 gNENs have significant disease requiring resection. Hence, endoscopic surveillance and resect strategy would benefit patients.

BACKGROUND: Procalcitonin (PCT) is a well-known marker for bacterial infection; however, the clinical significance of PCT in the long-term prognosis after colorectal cancer (CRC) surgery remains unclear. METHODS: This is a retrospective review of 277 patients that underwent CRC surgery to investigate the relationship between preoperative PCT, clinicopathological condition, cancer-specific overall survival (OS), and relapse-free survival (RFS). RESULTS: Median follow-up interval was 5.0 years in all patients. Thirty-six patients developed recurrence, and 46 patients died due to recurrences or metastases of CRC. Preoperative PCT levels were highest in Stage IV patients. The cancer-specific OS in patients with Stage IV/PCT ≤0.05 ng/mL was significantly higher than those with Stage IV/PCT >0.05 ng/mL (3 years survival; 42.3 vs. 14.3%, p = 0.0413). On multivariate analysis, gender, TNM classification, and PCT were identified as significant risk factors for cancer-specific OS in patients with Stage I-III CRC. The cancer-specific OS rate of these patients with PCT ≥0.08 ng/mL, compared with PCT <0.08 ng/mL, was significantly decreased (5 years survival; 59.1 vs. 92.7%, p < 0.0001). TNM classification was finally identified as an independent risk factor for cancer-specific RFS in these patients by multivariate analysis. CONCLUSION: High preoperative PCT values in CRC patients appeared to be associated with poor OS but not RFS following surgical treatments.

BACKGROUND: Elevated pretreatment carcinoembryonic antigen (CEA) levels are related to poor prognosis in patients with locally advanced rectal cancer (LARC) treated with neo-CRT followed by TME. In patients with normal pretreatment CEA levels, the prognostic significance of carbohydrate antigen 199 (CA199) is controversial. OBJECTIVES: The aim of this study was to explore the prognostic value of pretreatment serum CA199 in patients with LARC who had normal pretreatment CEA levels treated with neo-CRT followed by curative surgery. METHODS: A retrospective study of 456 patients with LARC treated with neo-CRT followed by TME between January 2006 and May 2017 was performed. We employed the maximal χ2 method to determine the CA199 threshold of 9.1 U/mL based on the difference in survival and divided patients into 2 groups. Group 1: patients with pretreatment s-CEA < 5 ng/mL and CA199 ≥ 9.1 U/mL. Group 2: patients with pretreatment s-CEA < 5 ng/mL and CA199 < 9.1 U/mL. Overall survival (OS) across CA199 was assessed using Cox proportional hazard regression models (PS:CEA ≥ 5 ng/mL was seen as elevated). RESULTS: Multivariate analyses demonstrated that the following factors were significantly related to OS in patients with LARC with normal pretreatment CEA levels: ypT (odds ratio [OR] 1.863, p = 0.030), ypN (OR 1.622, p = 0.026), and pretreatment CA199 levels (OR 1.886, p = 0.048). CONCLUSION: Pretreatment CA199 is an independent factor for OS in patients with LARC with normal pretreatment CEA levels, which may reach the clinic to guide individualized decision-making.

INTRODUCTION: Clinical benefits of laparoscopic surgery are well established, but evidence for financial benefits is limited. This study aimed to compare the financial impact of the introduction of laparoscopic colorectal surgery. METHODS: This study included patients who underwent colorectal surgery between January 2010 and 2015. We collected a range of financial data and divided the patients into 2 groups. Primary outcome was total cost defined by surgical-related costs. RESULTS: A total of 1,246 patients were included, of which 440 surgeries were performed laparoscopically. The total median cost of laparoscopy was higher compared to open surgery (EUR 4,665 vs. EUR 4,268, p = 0.001). Laparoscopy was associated with higher equipment costs (EUR 857 vs. EUR 232, p < 0.001), longer operating time (3.2 vs. 2.5 hours, p < 0.001), and more readmissions (10.9 vs. 8.5%, p < 0.001). However, after adjusting for heterogeneity, no difference was found in total cost. Surgical-related costs were counterbalanced by lower costs associated with shorter median hospital stay (6 vs. 9 days, p < 0.001), less morbidity (37.3 vs. 55.1%, p < 0.001), and less mortality (1.8 vs. 5.6%, p = 0.013) for laparoscopy. CONCLUSION: During the introduction of laparoscopy for colorectal surgery, no significant differences were found in total cost between laparoscopic and open colorectal surgery. However, favorable postoperative outcomes were achieved with laparoscopic surgery.
