Introduction
Flat-back syndrome is one of the main causes of surgical failure after lumbar fusion and can lead to a revision surgery to correct it. Three-column pedicle subtraction osteotomy is an efficient technique to restore lumbar lordosis (LL) for fixed sagittal malalignment. The fusion mass stemming from the past surgeries makes the procedure demanding as most anatomical landmarks are missing.Material and methods
This review article will focus on the correction of this lack of LL through the fusion mass. We will successively review the preoperative management, the surgical specificities, and various types of clinical cases that can be encountered in flat-back syndromes.Conclusion
PSO in the fixed fusion mass is technically demanding. Preoperative CT-scan and preoperative navigation allow us to push the limits when anatomical landmarks disappear. Bleeding and neurologic are the two major complications feared by the surgeon. The best way to avoid these revision surgeries is to restore a proper lumbar lordosis at the time of initial surgery by considering lumbo-pelvic indexes.Background
The aim of this study was to compare the outcomes of single-incision laparoscopic cholecystectomy (SILC) and conventional laparoscopic cholecystectomy (CLC).Method
Patients’ inclusion criteria were uncomplicated gallstones, BMI ≤30, ASA score ≤2, and no past surgery in the upper abdomen. Five surgeons performed only SILC and seven only CLC. Data analyzed included operative time, morbidity, quality of life (QOL), cosmetic result, and global patient satisfaction. The last three parameters were evaluated 3 months after surgery. QOL was assessed with the Gastrointestinal Quality of Life Index (GIQLI) questionnaire. Cosmetic result and patient satisfaction were rated using a 5-grade Likert scale.Results
This study included 104 patients operated on between April and June 2010. A SILC was performed in 35 patients and a CLC in 69. The preoperative characteristics of the two groups were similar. Median operative time for SILC was higher than that for CLC: 55 versus 40 min (p < 0.001). Postoperative complications (0 vs. 2) and postoperative GIQLI scores (123 ± 13 vs. 121 ± 18) were not significantly different between groups. Cosmetic result and patient satisfaction were better for SILC than for CLC. The percentages of results rated as excellent were 68 versus 37 % (p < 0.006) and 80 versus 57 % (p < 0.039), respectively. For the whole group, multivariate statistical analysis revealed that postoperative GIQLI score and cosmetic result were independent predictive factors of patient satisfaction. The percentages of satisfaction rated as excellent were greater in patients who had a postoperative GIQLI score ≥130 (92 vs. 49 %, odds ratio [OR] = 4, p < 0.001) and in patients who had an excellent cosmetic result (82 vs. 47 %, OR = 7, p < 0.001).Conclusions
Compared to CLC, SILC is associated with a longer operative time, an equivalent morbidity and QOL, and a better cosmetic result. The improved aesthetic result also leads to a better global patient satisfaction. 相似文献Flat-back syndrome is one of the main causes of surgical failure after lumbar fusion and can lead to a revision surgery to correct it.
