Effect of prolonged operative time on short-term outcomes of open vs minimally invasive proctectomy. J Gastrointest Surg 2024; 28:141-150. [PMID: 38445935 DOI: 10.1016/j.gassur.2023.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 10/19/2023] [Accepted: 11/30/2023] [Indexed: 03/07/2024]
Abstract
BACKGROUND Minimally invasive proctectomy (MIP) may offer advantages over open proctectomy (OP). Increased operative times (OTs) are linked to inferior outcomes for various operations; however, the interplay between OT and approach for proctectomy is not well-established. This study aimed to evaluate associations of increasing OT on 30-day morbidity in OP and MIP cohorts. METHODS The American College of Surgeons National Quality Improvement Program Targeted Proctectomy Dataset was used to identify patients undergoing proctectomy. Cases were stratified by open or minimally invasive surgical approach and following propensity score matching between the groups, and OT quartiles were established for each group. Perioperative outcomes were compared among quartiles, and multivariate regression was used to identify factors associated with prolonged OT. RESULTS The median OT was longer for MIP (271 vs 232 min; P < .01). Although increased OT was associated with higher overall morbidity for both open and minimally invasive approaches, this effect was more pronounced in OP than in MIP (63.2% vs 38.4%, respectively; P < .001). Factors associated with prolonged OT included the procedure performed, male sex, higher body mass index scores, diverting ileostomy, and, in malignant disease, mid or lower and T4 tumors (all P < .05). CONCLUSION Herein, prolonged OT was associated with worse short-term outcomes for both OP and MIP cases; however, its detrimental effect was more pronounced for open surgery than for minimally invasive surgery. Our data suggested that MIP may offer short-term advantages for demanding cases requiring longer OTs.

Abstract
BACKGROUND Increased operative time in colorectal surgery is associated with worse surgical outcomes. Laparoscopic and robotic operations have improved outcomes, despite longer operative times. Furthermore, the definition of "prolonged" operative time has not been consistently defined. OBJECTIVE The first objective was to define prolonged operative time across multiple colorectal operations and surgical approaches. The second was to describe the impact of prolonged operative time on length of stay and short-term outcomes. DESIGN A retrospective cohort study. SETTING Forty-two hospitals in the Surgical Care Outcomes Assessment Program from 2011 to 2019. PATIENTS There were a total of 23,098 adult patients (age 18 years or older) undergoing 6 common, elective colorectal operations: right colectomy, left/sigmoid colectomy, total colectomy, low anterior resection, IPAA, or abdominoperineal resection. MAIN OUTCOME MEASURES Prolonged operative time defined as the 75th quartile of operative times for each operation and approach. Outcomes were length of stay, discharge home, and complications. Adjusted models were used to account for factors that could impact operative time and outcomes across the strata of open and minimally invasive approaches. RESULTS Prolonged operative time was associated with longer median length of stay (7 vs 5 days open, 5 vs 4 days laparoscopic, 4 vs 3 days robotic) and more frequent complications (42% vs 28% open, 24% vs 17% laparoscopic, 27% vs 13% robotic) but similar discharge home (86% vs 87% open, 94% vs 94% laparoscopic, 93% vs 96% robotic). After adjustment, each additional hour of operative time above the median for a given operation was associated with 1.08 (1.06-1.09) relative risk of longer length of stay for open operations and 1.07 (1.06-1.09) relative risk for minimally invasive operations. LIMITATIONS Our study was limited by being retrospective, resulting in selection bias, possible confounders for prolonged operative time, and lack of statistical power for subgroup analyses. CONCLUSIONS Operative time has consistent overlap across surgical approaches. Prolonged operative time is associated with longer length of stay and higher probability of complications, but this negative effect is diminished with minimally invasive approaches.

EL IMPACTO DEL TIEMPO OPERATORIO PROLONGADO ASOCIADO CON LA CIRUGA COLORRECTAL MNIMAMENTE INVASIVA UN INFORME DEL PROGRAMA DE EVALUACIN DE RESULTADOS DE ATENCIN QUIRRGICA ANTECEDENTES:El aumento del tiempo operatorio en la cirugía colorrectal se asocia con peores resultados quirúrgicos. Las operaciones laparoscópicas y robóticas han mejorado los resultados, a pesar de los tiempos operatorios más prolongados. Además, la definición de tiempo operatorio "prolongado" no se ha definido de manera consistente.OBJETIVO:Primero, definir el tiempo operatorio prolongado a través de múltiples operaciones colorrectales y enfoques quirúrgicos. En segundo lugar, describir el impacto del tiempo operatorio prolongado sobre la duración de la estancia y los resultados a corto plazo.DISEÑO:Estudio de cohorte retrospectivo.ESCENARIO:42 hospitales en el Programa de Evaluación de Resultados de Atención Quirúrgica de 2011-2019.PACIENTES:23 098 pacientes adultos (de 18 años de edad y mayores), que se sometieron a seis operaciones colorrectales electivas comunes: colectomía derecha, colectomía izquierda/sigmoidea, colectomía total, resección anterior baja, anastomosis ileoanal con bolsa o resección abdominoperineal.PRINCIPALES MEDIDAS DE RESULTADO:Tiempo operatorio prolongado definido como el cuartil 75 de tiempos operatorios para cada operación y abordaje. Los resultados fueron la duración de la estancia hospitalaria, el alta domiciliaria y las complicaciones. Se usaron modelos ajustados para tener en cuenta los factores que podrían afectar tanto el tiempo operatorio como los resultados en los estratos de abordajes abiertos y mínimamente invasivos.RESULTADOS:El tiempo operatorio prolongado se asoció con una estancia media más prolongada (7 vs. 5 días abiertos, 5 vs. 4 días laparoscópicos, 4 vs. 3 días robóticos), complicaciones más frecuentes (42 % vs. 28 % abiertos, 24 % vs. 17 % laparoscópica, 27% vs. 13% robótica), pero similar alta domiciliaria (86% vs. 87% abierta, 94% vs. 94% laparoscópica, 93% vs. 96% robótica). Después del ajuste, cada hora adicional de tiempo operatorio por encima de la mediana para una operación determinada se asoció con un riesgo relativo de 1,08 (1,06, 1,09) de estancia hospitalaria más larga para operaciones abiertas y un riesgo relativo de 1,07 (1,06, 1,09) para operaciones mínimamente invasivas.LIMITACIONES:Nuestro estudio estuvo limitado por ser retrospectivo, lo que resultó en un sesgo de selección, posibles factores de confusión por un tiempo operatorio prolongado y falta de poder estadístico para los análisis de subgrupos.CONCLUSIONES:El tiempo operatorio tiene una superposición constante entre los enfoques quirúrgicos. El tiempo operatorio prolongado se asocia con una estadía más prolongada y una mayor probabilidad de complicaciones, pero este efecto negativo disminuye con los enfoques mínimamente invasivos.

Impact of operation duration on postoperative outcomes of minimally-invasive right colectomy. Colorectal Dis 2022; 24:1505-1515. [PMID: 35819005 DOI: 10.1111/codi.16243] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2022] [Revised: 06/04/2022] [Accepted: 06/23/2022] [Indexed: 01/07/2023]
Abstract
AIM Operation time (OT) is a key operational factor influencing surgical outcomes. The present study aimed to analyse whether OT impacts on short-term outcomes of minimally-invasive right colectomies by assessing the role of surgical approach (robotic [RRC] or laparoscopic right colectomy [LRC]), and type of ileocolic anastomosis (i.e., intracorporal [IA] or extra-corporal anastomosis [EA]). METHODS This was a retrospective analysis of the Minimally-invasivE surgery for oncological Right ColectomY (MERCY) Study Group database, which included adult patients with nonmetastatic right colon adenocarcinoma operated on by oncological RRC or LRC between January 2014 and December 2020. Univariate and multivariate analyses were used. RESULTS The study sample was composed of 1549 patients who were divided into three groups according to the OT quartiles: (1) First quartile, <135 min (n = 386); (2) Second and third quartiles, 135-199 min (n = 731); and (3) Fourth quartile ≥200 min (n = 432). The majority (62.7%) were LRC-EA, followed by LRC-IA (24.3%), RRC-IA (11.1%), and RRC-EA (1.9%). Independent predictors of an OT ≥ 200 min included male gender, age, obesity, diabetes, use of indocyanine green fluorescence, and IA confection. An OT ≥ 200 min was significantly associated with an increased risk of postoperative noninfective complications (AOR: 1.56; 95% CI: 1.15-2.13; p = 0.004), whereas the surgical approach and the type of anastomosis had no impact on postoperative morbidity. CONCLUSION Prolonged OT is independently associated with increased odds of postoperative noninfective complications in oncological minimally-invasive right colectomy.

The effect of operative duration on the outcome of colon cancer procedures. Surg Endosc 2021; 36:5076-5083. [PMID: 34782967 DOI: 10.1007/s00464-021-08871-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2021] [Accepted: 11/07/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Prolonged operative duration has been associated with increased post-operative morbidity in numerous surgical subspecialties; however, data are limited in operations for colon cancer specifically and existing literature makes unwarranted methodological assumptions of linearity. We sought to assess the effects of extended operative duration on perioperative outcomes in those undergoing segmental colectomy for cancer using a methodologically sound approach. METHODS We conducted a retrospective cohort study of patients undergoing segmental colectomy for cancer between 2014 and 2018, logged in the National Surgical Quality Improvement Program datasets. Our primary outcome was a composite of any complication within 30 days; secondary outcomes included length of stay and discharge disposition. Our main factor of interest was operative duration. RESULTS We analyzed 26,380 segmental colectomy cases, the majority of which were approached laparoscopically (64.95%) and were right sided (62.93%). Median operative duration was 152 (95% CI 112-206) minutes. On multivariable regression, increased operative duration was linearly associated with any complication (OR = 1.003, 95% CI 1.003-1.003, p < 0.0001) in the overall cohort, as was length of stay (p < 0.0001). All subgroups except for the laparoscopic left colectomy group were linearly associated with operative duration. In the laparoscopic left colectomy group, an inflection point in the odds of any complication was found at 176 min (OR = 1.39, 95% CI 1.20-1.61, p < 0.0001). CONCLUSIONS This study suggests that the risk of perioperative complications increases linearly with increasing operative duration, where each additional 30 min increases the odds of complication by 10%. In those undergoing laparoscopic left colectomy, the risk of complications sharply increases after ~ 3 h, suggesting that surgeons should aim to complete these procedures within 3 h where possible.

No need to watch the clock: persistence during laparoscopic sigmoidectomy for diverticular disease. Surg Endosc 2020; 35:2823-2830. [PMID: 32556770 DOI: 10.1007/s00464-020-07717-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Accepted: 06/09/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Laparoscopic sigmoidectomy is the preferred approach in the elective surgical management of diverticulitis. However, it is unclear if the benefits of laparoscopy persist when operative times are prolonged. We aimed to investigate if the recovery benefits associated with laparoscopy are retained when operative times are long. METHODS A retrospective review of a prospectively maintained database of patients who underwent elective laparoscopic sigmoidectomy from 2010-2015 at a single academic tertiary institution was performed. Operative times among laparoscopic completed cases were divided into quartiles, and patient outcomes were compared between the groups. RESULTS A total of 466 patients (median age: 58 ± 11.6 years, 58% females) underwent sigmoidectomy: 430 completed laparoscopically and 36 (7.7%) converted. Median operative time in laparoscopically completed cases was 188 min (IQR 154-230). There were no differences in morbidity (P = 0.52) or readmission rates (P = 0.22) among the quartiles. The 2nd and 4th operative time quartiles were associated with significantly longer length of stay (LOS) when compared to the fastest quartile (P = 0.003 and P = 0.002, respectively), but there was no increase in LOS as operative times progressed between the 2nd, 3rd, and 4th quartiles. LOS after conversion was longer but did not reach statistical significance when compared to laparoscopically completed operations in the longest quartile (5.0 vs 6.5 days, P = 0.075) CONCLUSIONS: Our data do not support preemptive conversion of laparoscopic sigmoidectomy to avoid prolonged operative times. As long as progress is safely being made, surgeons are justified to continue pursuing laparoscopic completion.

Risk Factors Related to Operative Duration and Their Relationship With Clinical Outcomes in Pediatric Patients Undergoing Roux-en-Y Hepaticojejunostomy. Front Pediatr 2020; 8:590420. [PMID: 33364222 PMCID: PMC7752895 DOI: 10.3389/fped.2020.590420] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2020] [Accepted: 10/14/2020] [Indexed: 11/13/2022] Open
Abstract
Background: Operative duration might be important for perioperative morbidity, and its involvement has not been fully characterized in pediatric patients. We identified perioperative variables associated with operative duration and determined their influence on clinical outcomes in pediatric patients. Methods: We retrospectively reviewed 701 patients who underwent elective removal of choledochal cysts followed by Roux-en-Y hepaticojejunostomy. The patients were separated into the long operative time group (>165 min) and short operative time group (<165 min) based on the median operative time (165 min). Propensity score matching was performed to adjust for any potential selection bias. The independent risk factors for operative time were determined using multivariable logistic regression analyses. Results: The operative time was often increased by excision difficulty caused by a larger choledochal cyst size (OR = 1.56; 95% CI, 1.09-2.23; p < 0.001), a greater BMI (OR = 1.02; 95% CI, 1.00-1.15; p = 0.018), and older age (OR = 1.17; 95% CI, 1.02-1.39; p = 0.012) in the multivariate analysis. A long surgical duration was associated with delayed gastrointestinal functional recovery, as measured using the time to first defecation (p = 0.027) and first bowel movement (p = 0.019). Significantly lower levels of serum albumin were found in the long operative time group than in the short operative time group (p = 0.0035). The total length of postoperative hospital stay was longer in patients in the long operative time group (7.51 ± 2.03 days) than in those in the short operative time group (6.72 ± 1.54 days, p = 0.006). Conclusions: Our data demonstrated that a short operative time was associated with favorable postoperative results. The influencing factors of operative time should be ameliorated to achieve better outcomes.

Operative Time as an Independent and Modifiable Risk Factor for Short-Term Complications After Knee Arthroscopy. Arthroscopy 2019; 35:2089-2098. [PMID: 31227396 DOI: 10.1016/j.arthro.2019.01.059] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2018] [Revised: 01/28/2019] [Accepted: 01/29/2019] [Indexed: 02/08/2023]
Abstract
PURPOSE To determine whether operative time is an independent risk factor for 30-day complications after arthroscopic surgical procedures on the knee. METHODS The American College of Surgeons National Surgical Quality Improvement Program database was queried between 2005 and 2016 for all arthroscopic knee procedures including lateral release, loose body removal, synovectomy, chondroplasty, microfracture, and meniscectomy. Cases with concomitant procedures were excluded. Correlations between operative time and adverse events were controlled for variables such as age, sex, body mass index, patient comorbidities, and procedure using a multivariate Poisson regression with robust error variance. RESULTS A total of 78,864 procedures met our inclusion and exclusion criteria. The mean age of patients was 51.0 ± 14.3 years; mean operative time, 31.2 ± 18.1 minutes; and mean body mass index, 31.0 ± 7.8. Arthroscopic lateral release (coefficient, 5.8; 95% confidence interval [CI], 4.8-6.8; P < .001), removal of loose bodies (coefficient, 4.2; 95% CI, 3.2-5.3; P < .001), synovectomy (coefficient, 1.8; 95% CI, 1.2-2.3; P < .001), and microfracture (coefficient, 6.5; 95% CI, 5.8-7.2; P < .001) had significantly greater durations of surgery in comparison with meniscectomy. The overall rate of adverse events was 1.24%. After we adjusted for demographic characteristics and the procedure, a 15-minute increase in operative duration was associated with an increased risk of transfusion (relative risk [RR], 1.5; 95% CI, 1.3-1.8; P < .001), death (RR, 1.6; 95% CI, 1.2-2.1; P = .005), dehiscence (RR, 1.6; 95% CI, 1.2-2.2; P = .002), surgical-site infection (RR, 1.3; 95% CI, 1.2-1.3; P = .001), sepsis (RR, 1.3; 95% CI, 1.2-1.4; P < .001), readmission (RR, 1.1; 95% CI, 1.1-1.2; P < .001), and extended length of stay (RR, 1.4; 95% CI, 1.3-1.4; P < .001). CONCLUSIONS Marginal increases in operative time are associated with an increased risk of adverse events such as surgical-site infection, sepsis, extended length of stay, and readmission. Efforts should be made to maximize surgical efficiency. LEVEL OF EVIDENCE Level IV, retrospective database study.

Do prolonged operative times obviate the benefits associated with minimally invasive colectomy? Surgery 2019; 166:336-341. [PMID: 31235244 DOI: 10.1016/j.surg.2019.05.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2019] [Revised: 04/11/2019] [Accepted: 05/04/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Minimally invasive colectomy is associated with improved length of stay and decreased postoperative morbidity. Little is known regarding the impact of prolonged operative time on the benefits afforded by minimally invasive colectomy. METHODS The American College of Surgeons National Surgical Quality Improvement Program procedure targeted colectomy dataset was queried to identify elective right and left colectomies performed between 2011 and 2017. Multivariable modeling was used to compare rates of composite 30-day death or serious morbidity, overall morbidity, mortality, anastomotic leak, surgical site infection, and length of stay for prolonged minimally invasive cases to those for average duration open cases. RESULTS A total of 16,602 right colectomies and 36,557 left colectomies were identified. Median operative times for open and minimally invasive right colectomies were 107 min and 129 min (P < .01), while that for open left colectomies was 128 min and 156 min for minimally invasive left colectomies (P < .01). Cohorts were stratified by quartiles of operative time with the highest (fourth) quartile defined as a prolonged operating time. When compared with an average duration open colectomy, prolonged minimally invasive right colectomies and left colectomies were associated with decreased risk-adjusted rates of overall morbidity, surgical site infection, and with lesser lengths of stay (P < .05). Prolonged minimally invasive left colectomies were also associated with improved rates of composite 30-day death or serious morbidity relative to average open left colectomies (odds ratio 0.66, 95% confidence interval, 0.54-0.79). CONCLUSION Prolonged operating times of an minimally invasive approach do not obviate the benefits of an minimally invasive approach to colectomy.

Longer Operating Time During Gastrectomy Has Adverse Effects on Short-Term Surgical Outcomes. J Surg Res 2019; 243:151-159.

Abstract
BACKGROUND Gastric cancer continues to be one of the malignant tumor types with high morbidity and mortality worldwide. Although remarkable improvements have been made to combat gastric cancer, surgery is still the first choice of treatment for gastric cancer. METHODS This was a single-center and retrospective study. A total of 110 patients who underwent radical gastrectomy with D2 lymph node dissection between 2014 and 2017 were included in this study, and all patients were treated by the same medical staff. Based on the median operating time, patients were grouped into a long-time group (>180 min) and a short-time group (≤180 min). Influences of operating time on outcomes of patients in the short-term and long-term groups were analyzed. RESULTS The long-time group showed a higher incidence of postoperative complications compared with the short time group (P < 0.01) with a significant decrease in serum albumin and the prognostic nutritional index value. Moreover, a long operating time was often caused by the operating start time (P < 0.001), excision difficulty caused by lager tumor size (P < 0.001), worse tumor differentiation, and deeper tumor invasion (P < 0.05). However, length of operating time did not significantly influence overall survival of patients who underwent radical gastrectomy. CONCLUSIONS The results suggested that operating time might be an indicator of the incidence of postoperative complication and that several important variables, such as prognostic nutritional index, serum albumin, operating start time, and excision time, could be intervened in the perioperative period to help patients gain a better outcome after gastrectomy.

Abstract
Background Laparoscopic surgery for rectal cancer is associated with improved postoperative outcomes compared to open surgery; however, economic studies have yielded contradictory results. The aim of this study was to compare the clinical and economic outcomes of laparoscopic versus open surgery for patients with rectal cancer. Methods Propensity score matching analysis was performed in a retrospective cohort of patients who underwent elective low anterior resection for rectal cancer treatment by laparoscopic and open surgery in a single Brazilian cancer center. Matched covariates included age, gender, body mass index, pTNM stage, American Society of Anesthesiologists score, type of anesthesia, neoadjuvant chemoradiotherapy, and interval between neoadjuvant chemoradiotherapy and index surgery. The clinical and economic outcomes were evaluated. The follow-up period was within 30 days of the index procedure. The clinical outcomes were reoperation, postoperative complications, operative time, length of stay in the intensive care unit, and postoperative hospital stay. For economic outcomes, a cost analysis was used to compare the costs. Results Initially, 220 patients were evaluated. After propensity score matching, 100 patients were included in the analysis (50 patients in the open surgery group and 50 patients in the laparoscopic surgery group). There were no differences in patients' baseline characteristics. Operative time was longer for laparoscopic surgery (247 minutes vs 285 minutes, P=0.006). There were no significant differences in other clinical outcomes. The hospital costs were similar between the two groups (Brazilian reais 21,233.15 vs Brazilian reais 21,529.28, P=0.115), although the intraoperative costs were higher for laparoscopic surgery, mainly owing to the surgical devices and the theater-related costs. The postoperative costs were lower for laparoscopic surgery, owing to lower intensive care unit, ward, and reoperation costs. Conclusion Laparoscopic surgery for rectal cancer is not costlier than open surgery from the health care provider's perspective, since the intraoperative costs were offset by lower postoperative costs. Open surgery tends to have a longer length of stay.

Robotic rectal cancer surgery in obese patients may lead to better short-term outcomes when compared to laparoscopy: a comparative propensity scored match study. Int J Colorectal Dis 2018; 33:1079-1086.

Abstract
PURPOSE Laparoscopic rectal surgery in obese patients is technically challenging. The technological advantages of robotic instruments can help overcome some of those challenges, but whether this translates to superior short-term outcomes is largely unknown. The aim of this study is to compare the short-term surgical outcomes of obese (BMI ≥ 30) robotic and laparoscopic rectal cancer surgery patients. METHODS All consecutive obese patients receiving laparoscopic and robotic rectal cancer resection surgery from three centres, two from the UK and one from Portugal, between 2006 and 2017 were identified from prospectively collated databases. Robotic surgery patients were propensity score matched with laparoscopic patients for ASA grade, neoadjuvant radiotherapy and pathological T stage. Their short-term outcomes were examined. RESULTS A total of 222 patients were identified (63 robotic, 159 laparoscopic). The 63 patients who received robotic surgery were matched with 61 laparoscopic patients. Cohort characteristics were similar between the two groups. In the robotic group, operative time was longer (260 vs 215 min; p = 0.000), but length of stay was shorter (6 vs 8 days; p = 0.014), and thirty-day readmission rate was lower (6.3% vs 19.7%; p = 0.033). CONCLUSIONS In this study population, robotic rectal surgery in obese patients resulted in a shorter length of stay and lower 30-day readmission rate but longer operative time when compared to laparoscopic surgery. Robotic rectal surgery in the obese may be associated with a quicker post-operative recovery and reduced morbidity profile. Larger-scale multi-centre prospective observational studies are required to validate these results.

Abstract
The robotic system has gained wide acceptance in specialties such as urological and gynecological surgery. It has also been applied in the field of upper gastrointestinal surgery. Since the first implementation of the robotic system for the treatment of gastric adenocarcinoma, the procedure has been found to be safe and feasible. Although robotic gastrectomy does not meet our expectations and yield better results than laparoscopic gastrectomy, this procedure seems to provide several advantages over laparoscopy such as reduced blood loss, shorter learning curves and increased number of retrieved lymph nodes. However, as many case series, including a recent multicenter study, have revealed, higher cost and longer operation time are the major limitations of robotic gastrectomy. Furthermore, there are no results from well-designed randomized clinical trials comparing the two procedures. New procedures in much more technically demanding cases will test the genuine benefits of robotic gastrectomy.

Abstract
BACKGROUND Laparoscopic colectomies are associated with reduced perioperative morbidity and mortality compared with open surgery. Nevertheless, many surgeons continue to utilize an open surgical approach due to the perceived benefits of shorter operative times. This study aims to compare the outcomes of laparoscopic versus open colectomies of equal or shorter operative duration. METHODS All patients undergoing elective laparoscopic or open colectomy in the American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) were identified from the years 2005 through 2012. Patients were stratified first by operative procedure including partial colectomy, total colectomy, or low anterior resection. Each surgical group was then divided into 4 groups according to operative time: <90 minutes, ≥90 minutes and <3 hours, ≥3 hours and <6 hours, and ≥6 hours. In total, 30-day outcomes were compared between laparoscopic operations and open procedures of shorter or equivalent durations within each surgical group. Multivariate logistic regression was utilized to account for differences in patient demographics and comorbidities between the surgical groups. RESULTS In total, 156,503 patients met inclusion criteria; 112,053 (71.6%) patients underwent a partial colectomy, 13,838 (8.8%) patients underwent a total colectomy, and 30,612 (19.6%) patients underwent a low anterior resection. A laparoscopic approach was used in 34% (37,789 patients) of the partial colectomies performed, 31% (4285 patients) of the total colectomies performed, and 45% (13,850 patients) of the low anterior resections performed. For all procedures, laparoscopic operations <6 hours were associated with superior outcomes compared with shorter open procedures. The benefit of laparoscopic operations was lost when operative time exceeded 6 hours. CONCLUSIONS Laparoscopic colectomies are associated with improved outcomes compared with open operations that do not exceed an operative time of 6 hours. Given the potential to improve patient outcomes, consideration should be given to the laparoscopic approach for all colon surgeries expected to be completed in <6 hours.

Looking inward: The impact of operative time on graft survival after liver transplantation. Surgery 2017; 162:937-949. [PMID: 28684160 DOI: 10.1016/j.surg.2017.05.010] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2017] [Revised: 04/27/2017] [Accepted: 05/12/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND Operative time often has been cited as an important factor for postoperative outcomes. Despite this belief, most efforts to improve liver transplant outcomes have largely focused on only patient and donor factors, and little attention has been paid on operative time. The primary objective of this project was to determine the impact of operative time on graft survival after liver transplant. METHODS A retrospective review of 2,877 consecutive liver transplants performed at a single institution was studied. Data regarding recipient, donor, and operative characteristics, including detailed granular operative times were collected prospectively and retrospectively reviewed. Using an instrument variable approach, Cox multivariate modeling was performed to assess the impact of operative time without the confounding of known and unknown variables. RESULTS Of the 2,396 patients who met the criteria for review, the most important factors determining liver transplant graft survival included recipient history of Hepatitis C (hazard ratio 1.45, P = .02), donor age (hazard ratio 1.23, P = .03), use of liver graft from donation after cardiac death donor (hazard ratio 1.50, P < .01), and operative time (hazard ratio 1.26, P = .01). In detailed analysis of stages of the liver transplant operation, the time interval from incision to anhepatic phase was associated with graft survival (hazard ratio 1.33; P = .02). CONCLUSION Using a novel instrument variable approach, we demonstrate that operative time (in particular, the time interval from incision to anhepatic time) has a significant impact on graft survival. It also seems that some of this efficiency is under the influence of the transplant surgeon.

The influence of patient- and surgeon-specific factors on operative duration and early postoperative outcomes in shoulder arthroplasty. J Shoulder Elbow Surg 2017; 26:1011-1016. [PMID: 28139387 DOI: 10.1016/j.jse.2016.10.025] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 10/06/2016] [Accepted: 10/26/2016] [Indexed: 02/01/2023]
Abstract
BACKGROUND Increased operative duration has been shown to have demonstrable effects on the outcomes and complications in multiple areas of orthopedic surgery. We sought to determine if patient- and surgeon-specific factors correlated to operative duration in shoulder arthroplasty. Our hypothesis was that increased surgeon and trainee volume would decrease operative times and that more complex pathology would increase operative duration. METHODS A retrospective review of primary and revision total and reverse shoulder arthroplasties performed at a single institution from 2012 through 2015 was performed evaluating the correlation between specific patient and surgeon factors and operative duration. The influence of operative duration on postoperative length of stay and risk of readmission within 30 days was also analyzed. RESULTS For surgeon-specific factors, high surgeon volume (>30 shoulder arthroplasties/year) was associated with shorter operative duration (105.9 vs. 128.3 minutes; P < .001). Progression through the fellowship academic year was found to be associated with decreased surgical times (100.7 vs. 116.5 minutes; P < .0001). Certain complex pathologic processes (reverse shoulder arthroplasty for sequelae of prior fracture, total shoulder arthroplasty for dysplastic glenoid morphology, revision surgery) showed increased operative times. Patients with postoperative readmission had a longer mean operative time (163 vs. 107.1 minutes). CONCLUSIONS Increased surgeon and trainee volumes were associated with decreased operative duration in shoulder arthroplasty. Patients with more complex pathology were more likely to have increased surgical times. Postoperative readmission within 30 days was associated with increased operative duration. Consideration of patient selection by surgeons to minimize operative times may reduce readmissions.

Laparoscopic vs open partial colectomy in elderly patients: Insights from the American College of Surgeons - National Surgical Quality Improvement Program database. World J Gastroenterol 2015; 21:12843-50.

Abstract
AIM To compare the outcomes between the laparoscopic and open approaches for partial colectomy in elderly patients aged 65 years and over using the American College of Surgeons - National Surgical Quality Improvement Program (ACS NSQIP) database. METHODS The ACS NSQIP database for the years 2005-2011 was queried for all patients 65 years and above who underwent partial colectomy. 1:1 propensity score matching using the nearest- neighbor method was performed to ensure both groups had similar pre-operative comorbidities. Outcomes including post-operative complications, length of stay and mortality were compared between the laparoscopic and open groups. χ(2) and Fisher's exact test were used for discrete variables and Student's t-test for continuous variables. P < 0.05 was considered significant and odds ratios with 95%CI were reported when applicable. RESULTS The total number of patients in the ACS NSQIP database of the years 2005-2011 was 1777035. We identified 27604 elderly patients who underwent partial colectomy with complete data sets. 12009 (43%) of the cases were done laparoscopically and 15595 (57%) were done with open. After propensity score matching, there were 11008 patients each in the laparoscopic (LC) and open colectomy (OC) cohorts. The laparoscopic approach had lower post-operative complications (LC 15.2%, OC 23.8%, P < 0.001), shorter length of stay (LC 6.61 d, OC 9.62 d, P < 0.001) and lower mortality (LC 1.6%, OC 2.9%, P < 0.001). CONCLUSION Even after propensity score matching, elderly patients in the ACS NSQIP database having a laparoscopic partial colectomy had better outcomes than those having open colectomies. In the absence of specific contraindications, elderly patients requiring a partial colectomy should be offered the laparoscopic approach.

Abstract
Robotic surgery for gastric cancer overcomes technical difficulties with laparoscopic gastrectomy. Its benefits include reduced intraoperative bleeding and shorter hospital stays; it is also easier to learn. Because accuracy increases during lymphadenectomy, a larger number of lymph nodes is likely to be retrieved using robotic gastrectomy. Higher costs and longer operation times have hindered the widespread adaptation and use of robotic surgery. In this review, we summarize the current status and issues regarding robotic gastrectomy.

Abstract
BACKGROUND Laparoscopic pancreaticoduodenectomy (LPD) is gaining momentum, but there is still uncertainty regarding its safety, reproducibility, and oncologic appropriateness. This review assesses the current status of LPD. METHODS Our literature review was conducted in Pubmed. Articles written in English containing five or more LPD were selected. RESULTS Twenty-five articles matched the review criteria. Out of a total of 746 LPD, 341 were reported between 1997 and 2011 and 405 (54.2 %) between 2012 and June 1, 2013. Pure laparoscopy (PL) was used in 386 patients (51.7 %), robotic assistance (RA) in 234 (31.3 %), laparoscopic assistance (LA) in 121 (16.2 %), and hand assistance in 5 (0.6 %). PL was associated with shorter operative time, reduced blood loss, and lower rate of pancreatic fistula (vs LA and RA). LA was associated with shorter operative time (vs RA), but with higher blood loss and increased incidence of pancreatic fistula (vs PL and RA). Conversion to open surgery was required in 64 LPD (9.1 %). Operative time averaged 464.3 min (338-710) and estimated blood 320.7 mL (74-642). Cumulative morbidity was 41.2 %, and pancreatic fistula was reported in 22.3 % of patients (4.5-52.3 %). Mean length of hospital stay was 13.6 days (7-23), showing geographic variability (21.9 days in Europe, 13.0 days in Asia, and 9.4 days in the US). Operative mortality was 1.9 %, including one intraoperative death. No difference was noted in conversion rate, incidence of pancreatic fistula, morbidity, and mortality when comparing results from larger (≥30 LPD) and smaller (≤29 LPD) series. Pathology demonstrated ductal adenocarcinoma in 30.6 % of the specimens, other malignant tumors in 51.7 %, and benign tumor/disease in 17.5 %. The mean number of lymph nodes examined was 14.4 (7-32), and the rate of microscopically positive tumor margin was 4.4 %. CONCLUSIONS In selected patients, operated on by expert laparoscopic pancreatic surgeons, LPD is feasible and safe.

Perioperative outcomes of laparoscopic and robot-assisted major hepatectomies: an Italian multi-institutional comparative study. Surg Endosc 2014; 28:2973-9.

Abstract
BACKGROUND Laparoscopic major hepatectomy (LMH), although safely feasible in experienced hands and in selected patients, is a formidable challenge because of the technical demands of controlling hemorrhage, sealing bile ducts, avoiding gas embolism, and maintaining oncologic surgical principles. The enhanced surgical dexterity offered by robotic assistance could improve feasibility and/or safety of minimally invasive major hepatectomy. The aim of this study was to compare perioperative outcomes of LMH and robotic-assisted major hepatectomy (RMH). METHODS Pooled data from four Italian hepatobiliary centers were analyzed retrospectively. Demographic data, operative, and postoperative outcomes were collected from prospectively maintained databases and compared. RESULTS Between January 2009 and December 2012, 25 patients underwent LMH and 25 RMH. The two groups were comparable for all baseline characteristics including type of resection and underlying pathology. Conversion to open surgery was required in one patient in each group (4%). No difference was noted in operative time, estimated blood, and need for allogenic blood transfusions. Intermittent pedicle occlusion was required only in LMH (32% vs. 0; p = 0.004). Length of hospital stay, including time spent in intensive care unit, was similar between the two groups, but patients undergoing LMH showed quicker recovery of bowel activity, with shorter time to first flatus (1 vs. 3 days; p = 0.023) and earlier tolerance to oral liquid diet (1 vs. 2 days; p = 0.001). No difference was noted in complication rate, 90-day mortality, and readmission rate. CONCLUSIONS This retrospective multi-institution study confirms that selected patients can safely undergo minimally invasive major hepatectomy, either LMH or RMH. The fact that intermittent pedicle occlusion could be avoided in RMH suggests improved surgical ability to deal with bleeding during liver transection, but further studies are needed before any final conclusion can be drawn.

Abstract
BACKGROUND As laparoscopic surgery is applied to colorectal surgery procedures, it becomes imperative to delineate whether there is an operative duration where benefits diminish. OBJECTIVE The purpose of this work was to determine whether benefits of a laparoscopic right colectomy compared with an open right colectomy are diminished by prolonged operative times. DESIGN We performed a retrospective analysis comparing outcomes of patients undergoing laparoscopic right and open right colectomy for colon cancer with operative duration of less than and greater than 3 hours. SETTINGS This study was based on data in the American College of Surgeons National Surgical Quality Improvement Program database. PATIENTS We queried the database for patients with laparoscopic and open right colectomy with a diagnosis of colorectal cancer between 2005 and 2010. MAIN OUTCOME MEASURES Patients were stratified by operative technique and duration. Forward multivariable logistic regression analysis was performed for mortality, cerebrovascular/cardiovascular complications, and infectious complications. Predictors of operative time >3 hours in the laparoscopic cohort were identified by logistic regression. RESULTS Of 4273 patients, operative duration was >3 hours for 18.4% of patients with a laparoscopic right colectomy and 11.3% with an open right colectomy. There was no benefit of the laparoscopic right colectomy with an operative duration >3 hours over open right colectomy with respect to mortality and cardiopulmonary and cerebrovascular complications. An operative duration >3 hours was an independent risk factor for infectious complications in patients undergoing a laparoscopic right colectomy. LIMITATIONS This was a retrospective study and not an intention-to-treat analysis. CONCLUSIONS At an operative duration of ≥3 hours, laparoscopic right colectomy has higher infectious complications than open right colectomy. Reduced mortality and less cardiopulmonary and cerebrovascular complications seen in the laparoscopic cohort with shorter operative duration were lost with an operative duration >3 hours. In patients at risk for prolonged laparoscopic right colectomy, early conversion to an open technique may be warranted.

Abstract
STUDY DESIGN Multicenter retrospective cohort study. OBJECTIVE To estimate the impact of increasing surgical duration on outcomes after single-level lumbar fusion. SUMMARY OF BACKGROUND DATA Lumbar fusion is a widely used practice for the treatment of disability and chronic low back pain. Longer operative duration is shown to correlate with increased morbidity and mortality in various surgical disciplines, but no large-scale study has been performed to validate this relationship in lumbar spine surgery. METHODS The American College of Surgeons National Surgical Quality Improvement Program was retrospectively reviewed to identify all patients who underwent lumbar fusion procedures during 2006 to 2011. Thirty-day morbidity and mortality rates were reported on the basis of operative time, whereas multivariate logistic regression model was used to examine operative duration as an independent risk factor for outcomes. RESULTS A total of 4588 patients were included in the analysis. The mean operative duration for all patients was 197 ± 105 minutes. Our multivariate risk-adjusted regression models demonstrated that increasing operative time was associated with step-wise increase in risk for overall complications (odds ratio [OR], 2.09-5.73), medical complications (OR, 2.18-6.21), surgical complications (OR, 1.65-2.90), superficial surgical site infection (OR, 2.65-3.97), and postoperative transfusions (OR, 3.25-12.19). Operative duration of 5 hours or more was also associated with increased risk of reoperation (OR, 2.17), organ/space surgical site infection (OR, 9.72), sepsis/septic shock (OR, 4.41), wound dehiscence (OR, 10.98), and deep vein thrombosis (OR, 17.22). CONCLUSION Our data suggest that increasing operative duration is associated with a wide array of complications. Operative duration is, therefore, an important quality metric in the performance of lumbar fusion. Strategies to reduce operative time and further research to identify risk factors that are associated with longer surgical duration are needed for improved patient outcomes. LEVEL OF EVIDENCE 3.

Predicting who will fail early discharge after laparoscopic colorectal surgery with an established enhanced recovery pathway. Surg Endosc 2013; 28:74-9. [PMID: 23982654 DOI: 10.1007/s00464-013-3158-2] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2013] [Accepted: 07/31/2013] [Indexed: 01/08/2023]
Abstract
BACKGROUND Despite using laparoscopy and enhanced recovery pathways (ERP), some patients are not ready for early discharge. The goal of this study was to identify predictors for patients who might fail early discharge, so that any defined factors might be addressed and optimized. METHODS A prospectively maintained database was reviewed for major elective laparoscopic colorectal surgical procedures. Cases were divided into day of discharge groups: ≤ 3 days and >4 days. All followed a standardized ERP. Demographic and clinical data were compared using Student's paired t tests or Fisher's exact test, with p value < 0.05 statistically significant. Regression analysis was performed to identify significant variables. RESULTS There were 275 ≤ 3 days patients and 273 >4 days patients. There were significant differences between groups in body mass index (p = 0.0123), comorbidities (p = 0.0062), ASA class (p = 0.0014), operation time (p < 0.001), postoperative complications (p < 0.001), and 30-day reoperation rate (p = 0.0004). There were no significant differences for intraoperative complications (p = 0.724), readmissions (p = 0.187), or mortality rate (p = 1.00). Significantly more patients were discharged directly home in the ≤ 3-days cohort. Using logistic regression, every hour of operating time increased the risk of length of stay >4 days by 2.35 %. CONCLUSIONS Elective colorectal surgery patients with longer operation times and more comorbidities are more likely to fail early discharge. These patients should have different expectations of the ERP, as an expected 1- to 3-day stay may not be achievable. By identifying patients at risk for failing early discharge, resources and postoperative support can be better allocated and patients better informed about likely recovery.
