Incidence of early complications requiring treatment plan changes after vitreoretinal surgery: a single-center study in South Korea

BACKGROUND

Information regarding incidence of treatment plan changes may be useful when discussing postoperative treatment plans for patients. Moreover, it may help establish a standardized postoperative treatment plan. This study aimed to evaluate the incidence of early complications requiring treatment plan changes in patients following vitreoretinal surgery and investigate its risk factors.

METHODS

This single-center retrospective study included 465 patients who had undergone vitreoretinal surgery. The reasons, incidence, and timing of treatment plan changes within 14 days of surgery were identified. Potential factors associated with the changes, such as patient demographics, surgeon's experience, diagnoses, and type of surgery were also analyzed.

RESULTS

The treatment plan was changed in 76 patients (16.3%) at a mean of 4.0 ± 3.2 days after vitreoretinal surgery. The reasons for the plan changes were increased intraocular pressure (IIOP) in 66(86.8%), intraocular inflammation in 2(2.6%), corneal edema in 3(3.9%), leakage from the sclerotomy wound in 3(3.9%) patients, and combined IIOP and intraocular inflammation in 2(2.6%). The date of discharge was postponed because of treatment plan changes in 17 patients (22.4%). The incidence of plan changes was higher in patients who underwent gas or oil tamponade (P < 0.001) and those who underwent surgery performed by less experienced surgeons (P = 0.034).

CONCLUSIONS

Treatment plan was changed in 16.3% of patients after vitreoretinal surgery. The risk of treatment plan changes was associated with the surgeon's experience in vitreoretinal surgery and the type of surgery. These results should be considered when establishing standardized care plans for patients who require vitreoretinal surgery.

Impact of surgeon's experience on outcome parameters following ureterorenoscopic stone removal

Within the BUSTER trial, we analyzed the surgeon's amount of experience and other parameters associated with URS procedures regarding the stone-free rate, complication rate, and operative time. Patient characteristics and surgical details on 307 URS procedures were prospectively documented according to a standardized study protocol at 14 German centers 01-04/2015. Surgeon's experience was correlated to clinical characteristics, and its impact on the stone-free rate, complication rate, and operative time subjected to multivariate analysis. 76 (25%), 66 (21%) and 165 (54%) of 307 URS procedures were carried out by residents, young specialists, and experienced specialists (> 5 years after board certification), respectively. Median stone size was 6 mm, median operative time 35 min. A ureteral stent was placed at the end of 82% of procedures. Stone-free rate and stone-free rate including minimal residual stone fragments (adequate for spontaneous clearance) following URS were 69 and 91%, respectively. No complications were documented during the hospital stays of 89% of patients (Clavien-Dindo grade 0). According to multivariate analysis, experienced specialists achieved a 2.2-fold higher stone-free rate compared to residents (p = 0.038), but used post-URS stenting 2.6-fold more frequently (p = 0.023). Surgeon's experience had no significant impact on the complication rate. We observed no differences in this study's main endpoints, namely the stone-free and complication rates, between residents and young specialists, but experienced specialists' stone-free rate was significantly higher. During this cross-sectional study, 75% of URS procedures were performed by specialists. The experienced specialists' more than two-fold higher stone-free rate compared to residents' justifies ongoing efforts to establish structured URS training programs.

Impact of the Surgical Experience on Leak Rate After Laparoscopic Sleeve Gastrectomy

INTRODUCTION

Laparoscopic sleeve gastrectomy (LSG) has become one of the most commonly performed bariatric procedures, largely due to several advantages it carries over more complex bariatric procedures. LSG is generally considered a straightforward procedure, but one of the major concerns is a staple line leak.

OBJECTIVE

The objectives of this study are to evaluate the correlation between surgeon's experience and leak rate and to assess the different risk factors for developing a gastric leak after LSG.

SETTING

Private hospital, France.

METHODS

The analysis of a single surgeon's yearly leak rate since the introduction of LSG for possible risk factors was done.

RESULTS

A total of 2012 LSGs were performed in between September, 2005 and December, 2014. Twenty cases (1 %) of gastric leak were recorded. Of these, 17 patients were women (94.4 %) with a mean age of 39.4 years (range 22-61) and mean body mass index (BMI) 41.2 kg/m(2) (range 34.8-57.1). On a yearly basis, the leak rate was 4.8 % (2006), 5.7 % (2007), 0 (2008), 2.6 % (2009), 2 % (2010), 0.8 % (2011), 0.6 % (2012), 0.2 % (2013), and 0 (2014). In the first 1000 cases (group A), there were 18 cases of gastric leak and in the last 1000 cases, there were 800 with GORE® SEAMGUARD® Bioabsorbable Staple Line Reinforcement (group B) 2 cases of gastric leak (p = 0.009). A revisional LSG, 395 patients after gastric banding and 61 patients re-sleeve gastrectomy, was performed in 456 cases (22.7 %). There were 3 cases of leak (0.65 %). There were two deaths.

CONCLUSION

LSG can be performed with a low complication rate. This large series of a single surgeon's experience demonstrated that the leak rate after LSG could be significantly decreased over time with changes in techniques.
