RESUMEN

BACKGROUND: The volume of the gastric reservoir appears crucial to explain the success of laparoscopic sleeve gastrectomy (LSG) in the treatment of morbid obesity. The aims of this study were to describe a new, easy model to estimate gastric reservoir volume after LSG; to evaluate the volumetric changes 1 year after surgery; and to analyze their relationship with weight loss. METHODS: This is a prospective observational study of all patients undergoing LSG in the Department of Surgery at our institution. The gastric reservoir was evaluated radiologically considering the image as a complex geometrical shape with two components: a cylinder (gastric body) and a truncated cone (antrum). Radiologic assessment using this new model was performed at 1 and 12 months after surgery. Moreover, body mass index and percentage of excess weight loss (%EWL) were evaluated at 3, 6, 12, and 18 months after LSG. RESULTS: Forty-five patients (34 F/11 M) with a mean age of 46.9 years were included. A significant increase in total gastric reservoir volume (124.8 ± 58.7 and 188.6 ± 76.4 mL at 1 and 12 months, respectively; p = 0.001) was observed. No statistically significant differences were observed comparing volume of the two components at the two time points. The %EWL at 18 months was inversely correlated with reservoir volume changes at 12 months after LSG (p = 0.006). CONCLUSIONS: We describe an easy volumetric model to estimate the size of the gastric reservoir after LSG. Moreover, a direct relationship between an increase in gastric reservoir volume and a lower weight loss after surgery was documented.

RESUMEN

Objetivo Analizar los resultados del abordaje quirúrgico laparoscópico frente al abierto en el tratamiento de las úlceras pépticas perforadas (UPP).Pacientes y métodos Estudio retrospectivo de todos los pacientes operados de una UPP durante el periodo enero de 2002-marzo de 2012. Se analizaron datos demográficos, tiempo operatorio, complicaciones y estancia hospitalaria. Resultados Se incluyó a 112 pacientes (mediana, 49 años), 60 en el grupo laparoscópico y 52 en el grupo abierto. Los pacientes operados por vía laparoscópica eran significativamente más jóvenes y tenían un mayor consumo de tabaco, alcohol y cannabis. La mediana de duración de los síntomas agudos fue menor en los pacientes del grupo laparoscópico (6 h) en comparación con los del grupo abierto (12 h). La mediana del tiempo operatorio fue significativamente mayor en los pacientes del grupo laparoscópico (104,5 vs. 76 min; p = 0,025). El porcentaje de conversión a cirugía abierta fue del 25%. La morbilidad fue similar en ambos grupos, pero 3 pacientes fallecieron en el grupo abierto. La mediana de estancia hospitalaria fue significativamente menor en el grupo laparoscópico (6 vs. 8 días; p = 0,041).Conclusión El abordaje por vía laparoscópica es una técnica segura y comparable a la cirugía abierta en el tratamiento de la UPP, con la que el paciente se beneficia de una estancia hospitalaria más corta (AU)

Objective To analyse the outcomes of laparoscopic versus open repair for perforated peptic ulcers (PPU).Methods All patients undergoing PPU repair between January 2002 and March 2012 were included in the study. Demographic characteristics, operation time, complications, and length of hospital stay were evaluated. Results Two hundred and twelve patients (median age, 49 years) were included, 60 in the laparoscopic group and 52 in the open group. Patients operated laparoscopically were significantly younger and had a higher consumption of tobacco, alcohol and cannabis. Median acute symptoms time was shorter in the laparoscopic group (6 h) compared to the open group (12 h; P=.025) Symptoms time was shorter in the laparoscopic group. Median operating time was significantly longer in the laparoscopic group (104.5 min vs. 76 min, P=.025). The percentage of conversion to open repair was 25%. There was no difference in morbidity between 2 groups, but there were 3 deaths in the open group. Median hospital stay was significantly shorter in patients treated laparoscopically when compared with the open group (6 days vs. 8 days; P=.041).Conclusion Laparoscopic and open repair are equally safe in the management of PPU. A shorter hospital stay can be achieved in the laparoscopic group (AU)
