Procedimiento de Whipple: experiencia de un centro en fase de crecimiento en cirugía hepato-bilio-pancreática / Whipple procedure: hepatic-bilio-pancreatic single center experience

La operación de Whipple es el procedimiento quirúrgico de mayor complejidad en cirugía abdominal, este se realiza en pacientes con tumores de la encrucijada pancreatoduodenal, es la única alternativa para tratamiento curativo en fases tempranas de la enfermedad. Objetivo: Determinar los resultados del procedimiento Whipple, en pacientes intervenidos con tumores de la encrucijada pancreatoduodenal en el Hospital General de Enfermedades del Instituto Guatemalteco de Seguridad Social, en el periodo de enero 2,015 a enero 2,020. Método: Descriptivo, observacional, retrospectivo. Resultados: Se incluyeron 42 procedimientos de Whipple, 29 (69%) casos del género masculino y 13 (31%) para el género femenino. La edad media fue de 61.5 años, el 54% presentaban comorbilidad asociada. El 24% utilizo transfusión transoperatoria de hemoderivados, el tiempo quirúrgico de 5.5 horas. La reintervención fue del 4.7%. Complicaciones postoperatorias tempranas 18%. La histología más común fue el carcinoma de cabeza de páncreas en el 43%. La mortalidad postoperatoria temprana fue del 4.7%. El OR de complicaciones asociadas a comorbilidades fue de 1.7 con un IC 0.3046-7.20 y un valor de P: 0.9251 que no es estadísticamente significativo. Conclusiones: Los tumores pancreatoduodenales en nuestra población se presentan en edades más tempranas a lo reportado. La morbimortalidad es similar a lo reportado en otros estudios a nivel latinoamericano, sin embargo las complicaciones están más elevadas que las mejores series internacionales. No existe asociación entre el riesgo de complicaciones con comorbilidades del paciente. (AU)

Whipple operation is the most complex surgical procedure in abdominal surgery, it's performed in patients with tumors of the pancreaticoduodenal crossroads, it is the only alternative for curative treatment in early stages of the disease. Objective: To determine the results of the Whipple procedure in patients operated on with tumors of the ancreaticoduodenal crossroads at the Hospital General de Enfermedades del IGSS in the period from January 2015 to January 2020. Method: Descriptive, observational, retrospective. Results: fourtytwo Whipple procedures were included, 29 (69%) cases of the male gender and 13 (31%) for the female gender. The mean age was 61.5 years, 54% had associated comorbidity. Twentyfour percent used intraoperative transfusion of blood products and surgical time of 5.5 hours. Reoperation was 4.7% with early postoperative complications of 18%. The most common histology was carcinoma of the head of the pancreas in 43%. Early postoperative mortality was 4.7%. The OR of complications associated with comorbidities was 1.7 with a CI 0.3046-7.20 and a P value: 0.9251, which is not statistically significant. Conclusions: Pancreaticoduodenal tumors in our population present at an earlier age than reported. Morbidity and mortality is similar to that reported in other studies. There is no association between the risk of complications with patient comorbidities. (AU)

Low serum albumin is not a contraindication for early iatrogenic bile duct injury repair.

UNLABELLED: Most iatrogenic bile duct injuries are recognized in the early postoperative period (first 48 hours). These patients usually have additional complications such as a suboptimal hydroelectrolitic status, subhepatic collections, external biliary fistula and malnutrition. In these circumstances, besides the elevation of bilirubin and transaminases associated with the injury, hypoalbuminemia is frequently encountered. The timing for repair is decided according to the condition of each patient. We report the impact of preoperative abnormal low serum albumin levels on the results of biliary tract reconstruction after a iatrogenic biliary lesion. METHOD: Patients who underwent biliary reconstruction in our center from 1998 to 2002 were analyzed. Only patients with complex injuries (Strasberg E, Bismuth III-IV, Stewart-Way III) were included. Major postoperative complications were recorded and correlated with preoperative liver function tests. RESULTS: Seventy seven patients were analyzed. In 41 cases, the injury was a consequence of a laparoscopic operation. All patients were treated by a Roux-en-Y hepatojejunostomy. No operative mortality was recorded. The most frequent postoperative complications were postoperative biliary fistula (8/77-9%, p < 0.017) and subhepatic collections (9/77-9%, p < 0.39). All fistulae closed spontaneously and the subhepatic collections were drained. Overall, complications were more common in the group with hypoalbuminemia (p < 0.002). CONCLUSION: Early repair is indicated if there is no systemic contraindication (sepsis, multiple organic failure, electrolytic imbalance). Abnormalities in the liver function tests, particularly a low serum albumin, should not delay the operation. Although significantly more postoperative complications are observed in an early repair, long-term results are comparable to those of an elective repair.
