Single-incision laparoscopic gastric banding has been reported to be safe and feasible. This matched case-control study is the first to compare the outcome in terms of weight loss and comorbidity improvement and band positioning of single-incision versus conventional laparoscopic gastric banding with 1-year follow-up.
Patients undergoing gastric banding surgery by one surgeon (S.V.) were prospectively entered into a database. Data collected included basic demographics, perioperative parameters, early and late postoperative (PO) morbidity, weight loss, and phi angle. Ten patients who underwent a single-incision gastric banding procedure were matched one-to-two with 20 patients undergoing conventional gastric banding from a database of 151 patients. Match was obtained according to gender, body mass index (BMI) ± 4 kg/m(2), age ± 8 years, and presence of at least one comorbidity in common. Generalized linear mixed models were used for statistical analysis.
Patients' initial characteristics were similar: SIL and conventional, respectively: sex (female:male) 9:10 and 18:20; age (years): 36.5 ± 10 and 37.5 ± 9; preoperative BMI (kg/m(2)): 41.8 ± 4 and 42.4 ± 3; weight (kg): 110.2 ± 13 and 117.9 ± 13; hospital stay (days): 1 and 1; operative time (min): 106.6 ± 24 and 100.9 ± 22. No significant differences were found in patients' BMI or excess weight loss during 1-year follow-up. The phi angles of the bands varied in a comparable range: PO day 1 (degrees): 62 ± 13 and 59 ± 15; PO week 6: 55 ± 9 and 54 ± 11, for SIL and conventional, respectively.
In this matched case-controlled study, single-incision laparoscopic adjustable gastric banding surgery outcomes were similar to those of the conventional multi-trocar laparoscopic operation. Band position as described by phi angle was also similar in the two groups. These results suggest that use of a single-incision approach does not compromise the results or band positioning of gastric banding surgery.
经单切口腹腔镜胃束带术已被报道为安全可行。本匹配病例对照研究首次比较了 1 年随访时的减重和合并症改善以及带位置的结果，比较了单切口与传统腹腔镜胃束带术。
一位外科医生（S.V.）进行胃束带手术的患者被前瞻性地纳入数据库。收集的数据包括基本人口统计学、围手术期参数、早期和晚期术后（PO）发病率、体重减轻和 phi 角。10 名接受单切口胃束带术的患者与数据库中 151 名患者中的 20 名接受传统胃束带术的患者进行了一对一的匹配。根据性别、体重指数（BMI）±4kg/m2、年龄±8 岁和共同存在至少一种合并症进行匹配。使用广义线性混合模型进行统计分析。
患者的初始特征相似：SIL 和常规，分别为：性别（女性：男性）9：10 和 18：20；年龄（岁）：36.5±10 和 37.5±9；术前 BMI（kg/m2）：41.8±4 和 42.4±3；体重（kg）：110.2±13 和 117.9±13；住院天数（天）：1 和 1；手术时间（分钟）：106.6±24 和 100.9±22。在 1 年随访期间，患者的 BMI 或超重减轻没有显著差异。带的 phi 角在可比范围内变化：PO 第 1 天（度）：62±13 和 59±15；PO 第 6 周：55±9 和 54±11，分别为 SIL 和常规。
在这项匹配病例对照研究中，单切口腹腔镜可调胃束带术的结果与传统的多套管腹腔镜手术相似。两组的 phi 角描述的带位置也相似。这些结果表明，使用单切口方法不会影响胃束带术的结果或带位置。
