Increased Postoperative Morbidity Associated With Prolonged Laparoscopic Colorectal Resections Is Not Increased by Resident Involvement

An Ethical Framework for Disclosing the Training Status and Roles of Resident-Level Surgeons to Patients

The concept of informed consent includes disclosure of all information that a reasonable patient would need to make a well-informed decision about whether to undergo a surgical procedure. This has traditionally been defined as including diagnosis, details about the procedure, prognosis, potential risks, and alternative treatments. The operating surgeon has final say and responsibility for the case, but the actual operation may be done (under supervision) by a surgeon in training. In this paper, we discuss the ethical dimensions of disclosing resident involvement, reviewing considerations such as established legal and professional standards, consequences for patients and for the surgical educators responsible for preparing future generations of surgeons, and patient rights. We conclude by offering a novel ethical framework intended to serve as a guide to disclosing resident involvement as part of the overall consent process.

The Impact of Prolonged Operative Time Associated With Minimally Invasive Colorectal Surgery: A Report From the Surgical Care Outcomes Assessment Program

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. See Video Abstract .

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

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.

Does resident autonomy in colectomy procedures result in inferior clinical outcomes?

BACKGROUND

The amount of time surgical trainees spend operating independently has been reduced by work-hour restrictions and shifts in the health care environment that impede autonomy. Few studies evaluate the association between clinical outcome and resident autonomy.

METHODS

The Veterans Affairs Surgical Quality Improvement Program database was queried to identify patients undergoing partial colectomy for neoplasm between 2004 and 2019. Rectal resections, emergency procedures, and those involving postgraduate year 1 and 2 residents were excluded. Records were categorized as performed with the attending scrubbed or not scrubbed. Hierarchical logistic regression was used to identify factors independently associated with operative time, morbidity, and mortality.

RESULTS

In total, 7,347 patients met inclusion criteria; 6,890 (93.6%) were categorized as attending scrubbed and 457 (6.4%) as attending not scrubbed. The cohorts were similar in terms of patient demographics, including age, race, body mass index, and American Society of Anesthesiologists class. There were no differences between cohorts in terms of operative time (attending not scrubbed 3.02 hours, attending scrubbed 3.07 hours, P = .42). On hierarchical logistic regression adjusted for age, gender, race, body mass index, functional status, cancer location, facility operative level, wound class, American Society of Anesthesiologists class, length of operation, operative modality (open or minimally invasive), postgraduate year of resident, and year, there were no differences in odds of complications, major morbidity, or mortality based on attending involvement.

CONCLUSION

Colectomies performed by residents with appropriate levels of autonomy are efficient and safe. Our results indicate that attending surgeon judgment regarding resident autonomy is sound and that educational environments can be designed to foster resident independence and preserve clinical quality, safety, and efficiency.

Independent Operating by General Surgery Residents: An ACS-NSQIP Analysis

OBJECTIVE

Surgical resident autonomy during training is paramount to independent practice. We sought to determine prevalence of general surgery resident autonomy for surgeries commonly performed on emergency general surgery services and identify trends with time.

DESIGN

We queried ACS-NSQIP for patients undergoing one of 7 emergency general surgery operations. We evaluated trends in independent operating (defined as a resident operating alone, without attending having scrubbed) over the study period. Other outcomes of interest: operative time, 30-day-mortality and complications.

SETTING

The ACS-NSQIP database.

PARTICIPANTS

Patients undergoing one of 7 emergency general surgery operations.

RESULTS

Data regarding resident involvement was only available for the years 2005-2010. 90,790 operations were performed, 922 (1%) by residents operating independently. Appendectomy accounted for 61% independent cases. Independent resident operating was associated with a longer operative time (65 versus 58 minutes, p < 0.001), but lower risk of bleeding requiring transfusion (p < 0.001) and progressive renal insufficiency (p = 0.02). Independent operating was not associated with increased risk of complications/mortality.

CONCLUSION

Independent resident operating is rare, even with increasing attention to its importance, and is not associated with increased complications or mortality. National data on this subject is old and not currently collected. There is need for a national registry on resident involvement to understand the current effect of independent operating on outcomes.

Laparoscopic-endoscopic cooperative surgery for ileal lipoma: A case report

This is the first report of laparoscopic-endoscopic cooperative surgery (LECS) for an ileal tumor. A 50-year-old man was admitted to our hospital with a positive fecal occult blood test. Colonoscopy detected a submucosal tumor with intussusception located in the ileum, 10 cm oral from the Bauhin valve. On further examination, he was diagnosed with an ileal lipoma. There were no signs of malignancy. LECS was performed for the ileal tumor. After submucosal elevation by injecting saline solution, a mucosal incision was made circumferentially along the tumor. A full-thickness incision was created endoscopically and laparoscopically on the circumferential mucosal incisional line. The tumor was withdrawn intraluminally by endoscopy. The defect of the ileal wall was closed laparoscopically in an axial direction with linear staplers. Histologically, the tumor was a 25-mm ileal lipoma with negative resection margins and no malignancy.
