Pancreatectomía corporocaudal laparoscópica y robótica, de elección y de futuro / Laparoscopic and robotic distal pancreatectomy: The choice and the future

Introducción La pancreatectomía distal (PD) mínimamente invasiva (MIS) está actualmente bien establecida, ya sea mediante técnica laparoscópica (PDL) o robótica (PDR).MétodosDe 83 PD realizadas entre enero del 2018 y marzo del 2022, se realizaron 57 casos (68,7%) mediante MIS, 35 PDL y 22 PDR (da Vinci Xi). Se evalúa la experiencia de ambos procedimientos y el valor del abordaje robótico. Se analizan en detalle los casos de conversión.ResultadosEl tiempo quirúrgico medio en las PDL y PDR fue de 201,2 (DE 47,8) y 247,54 (DE 35,8) min, (p=0,486). No se observaron diferencias en estancia hospitalaria ni en tasa de conversión, 6 (5-34) vs. 5,6 (5-22) días y 4 (11,4%) vs. 3 (13,6%) casos, respectivamente, (p=0.126). La tasa de reingresos fue de 3/35 (11,4%) y 6/22 (27,3%) casos, PDL vs. PDR respectivamente, (p=0.126).No existieron diferencias en morbilidad (Dindo-Clavien ≥ III) entre ambos grupos. La mortalidad fue de un caso en el grupo robótico (un paciente con conversión precoz por afectación vascular). La tasa de resecciones R0 fue mayor en el grupo robótico (77,1% vs. 90,9%) alcanzando la significación estadística, p=0,04.ConclusionesLa PDMIS es un procedimiento seguro y factible en pacientes seleccionados. Una planificación quirúrgica y la implementación escalonada basada en la experiencia previa ayudan a afrontar procedimientos técnicamente exigentes. Se sugiere que la PDR podría ser el abordaje de elección en la pancreatectomía corporocaudal, no siendo inferior a la PDL. (AU)

Introduction Distal pancreatectomy (DP) is currently well established as a minimally invasive surgery (MIS) procedure, using either a laparoscopic (LDP) or robotic (RDP) approach.MethodsOut of 83 DP performed between January 2018 and March 2022, 57 cases (68.7%) were performed using MIS: 35 LDP and 22 RDP (da Vinci Xi). We have assessed the experience with the 2techniques and analyzed the value of the robotic approach. Cases of conversion have been examined in detail.ResultsThe mean operative times for LDP and RDP were 201.2 (SD 47.8) and 247.54 (SD 35.8)min, respectively (p=0,486). No differences were observed in length of hospital stay or conversion rate: 6 (5–34) vs. 5.6 (5–22) days, and 4 (11.4%) vs. 3 (13.6%) cases, respectively (p=0.126). The readmission rate was 3/35 patients (11.4%) treated with LDP and 6/22 (27.3%) cases of RDP (p=0.126).There were no differences in morbidity (Dindo-Clavien≥III) between the 2groups. Mortality was one case in the robotic group (a patient with early conversion due to vascular involvement). The rate of R0 resection was greater and statistically significant in the RDP group (77.1% vs. 90.9%) (P=,04).ConclusionsMinimally invasive distal pancreatectomy (MIDP) is a safe and feasible procedure in selected patients. Surgical planning and stepwise implementation based on prior experience help surgeons successfully perform technically demanding procedures. RDP could be the approach of choice in distal pancreatectomy, and it is not inferior to LDP. (AU)

Realidad aumentada en cirugía hepato-bilio-pancreática. Una tecnología al alcance de la mano / Augmented reality in hepatobiliary-pancreatic surgery: A technology at your fingertips

La realidad aumentada es una tecnología que abre nuevas posibilidades en cirugía. Se presenta su implementación en una unidad de cirugía hepato-bilio-pancreática en relación con la planificación preoperatoria, el soporte intraoperatorio y la docencia. Para la planificación quirúrgica se han utilizado reconstrucciones 3D de la TC y de la RMN para hacer una evaluación de casos complejos, siendo la interpretación de la anatomía más precisa, y la planificación de la técnica más simple. A nivel intraoperatorio ha permitido la conexión remota holográfica entre especialistas, la substitución de elementos físicos por elementos virtuales, y el uso de modelos virtuales de consulta y guía quirúrgica. En docencia se han impartido clases que incluyen la retransmisión de una cirugía con el soporte de elementos virtuales para una mejor comprensión por parte de los estudiantes. Siendo la experiencia satisfactoria, la realidad aumentada podría aplicarse en el futuro de la cirugía hepato-bilio-pancreática para mejorar sus resultados. (AU)

Augmented reality is a technology that opens new possibilities in surgery. Its implementation in a hepatobiliary-pancreatic surgery unit is presented in relation to preoperative planning, intraoperative support and teaching. For surgical planning, 3D CT and MRI reconstructions have been used to evaluate complex cases, making the interpretation of the anatomy more precise and the planning of the technique simpler. At an intraoperative level, it has allowed remote holographic connection between specialists, the substitution of physical elements for virtual elements, and the use of virtual consultation models and surgical guides. In teaching, new lessons include the retransmission of a surgery with the support of virtual elements for a better understanding by the students. Being the experience satisfactory, augmented reality could be applied in the future of hepatobiliary-pancreatic surgery to improve its results. (AU)

RESULTS: The mean operative times for LDP and RDP were 201.2 (SD 47.8) and 247.54 (SD 35.8) minutes, respectively (P = NS). No differences were observed in length of hospital stay or conversion rate: 6 (5-34) vs. 5.6 (5-22) days, and 4 (11.4%) vs. 3 (13.6%) cases, respectively (P = NS). The readmission rate was 3/35 patients (11.4%) treated with LDP and 6/22 (27.3%) cases of RDP (P = NS). There were no differences in morbidity (Dindo-Clavien ≥ III) between the two groups. Mortality was one case in the robotic group (a patient with early conversion due to vascular involvement). The rate of R0 resection was greater and statistically significant in the RDP group (77.1% vs. 90.9%) (P = .04).

Surgical planning and stepwise implementation based on prior experience help surgeons successfully perform technically demanding procedures. RDP could be the approach of choice in distal pancreatectomy, and it is not inferior to LDP.

Augmented reality in hepatobiliary-pancreatic surgery: a technology at your fingertips.

Augmented reality is a technology that opens new possibilities in surgery. We present our experience in a hepatobiliary-pancreatic surgery unit in terms of preoperative planning, intraoperative support and teaching. For surgical planning, we have used 3D CT and MRI reconstructions to evaluate complex cases, which has made the interpretation of the anatomy more precise and the planning of the technique simpler. At an intraoperative level, it provides for remote holographic connection between specialists, the substitution of physical elements for virtual elements, and the use of virtual consultation models and surgical guides. In teaching, new lessons include sharing live video of surgery with the support of virtual elements for a better student understanding. As the experience has been satisfactory, augmented reality could be applied in the future to improve the results of hepatobiliary-pancreatic surgery.

Indocyanine green (ICG) fluorescent cholangiography in laparoscopic cholecystectomy: Simplifying time and dose.

BACKGROUND: This article aims to analyze and to simplify the optimal dose and time of intravenous indocyanine green (ICG) administration to achieve the identification of the cystic duct and the common bile duct (CBD). METHODS: A consecutive series of 146 patients was prospectively analyzed and divided into three groups according to the time of ICG administration: at induction of anesthesia group (20-30 min); hours before group (between 2 and 6 h); and the day before group (≥6 h); and two groups according to the dose of ICG: 1 cc (2.5 mg) or weight-based dose (0.05 mg/kg). RESULTS: The CBD was better visualized in the at induction of anesthesia group (85.4%), in the hours before group (97.1%) (p = 0.002) and in the 1cc group (p = 0.011). When we analyzed the 1 cc group (n = 126) a greater visualization of the CBD was observed in the at induction of anesthesia group (86.7%) and in the hours before group (97.1%) (p = 0.027). CONCLUSION: Due to its simplicity and reproducibility, we suggest a dose of 2.5 mg administered 2-6 h before the procedure is the optimal. However, ICG administered 30 min prior to the surgery is enough for adequate visualization of biliary structures.

Gastroplastia de Collis robótica / Robotic approach for Collis gastroplasty

El verdadero esófago corto es una entidad que causa mucha controversia entre los cirujanos. Se han publicado estudios acerca de su diagnóstico y tratamiento laparoscópico, sin que a día de hoy existan publicaciones del tratamiento con abordaje robótico. Presentamos, en forma de caso clínico, nuestra experiencia en cirugía robótica de hernia de hiato con verdadero esófago corto tratada con gastroplastia de Collis y fundoplicatura de Toupet. La cirugía robótica en el verdadero esófago corto puede facilitar la disección mediastínica y permitir una técnica de sutura más precisa. Son necesarios estudios para comparar los resultados a largo plazo de esta técnica quirúrgica entre el abordaje laparoscópico convencional y el abordaje robótico
