Objective: No consensus criteria have been established regarding ideal candidates for indirect decompression with lateral lumbar interbody fusion (LLIF), and contributing factors of indirect decompression failure were rarely reported. We aim to investigate the success rate of indirect decompression by LLIF with proposed selection criteria and identify risk factors associated with indirect decompression failure, defined as persistent pain requiring revision with direct decompression. Methods: Data from 191 patients undergoing LLIF were retrospectively reviewed. All the following criteria must be fulfilled: (1) dynamic clinical symptoms (pain relief in supine position), (2) presence of reducible disc height (recovered disc height in supine position), (3) no profound weakness, and (4) no static stenosis. The success rate of indirect decompression with LLIF and results after at least 1 year of follow-up were collected. Preoperative, procedure-related, and postoperative factors were assessed for their relationship with failure. Results: Of 191 patients,13 patients (6.8%) required additional direct decompression due to persistent pain, giving a criteria success rate of 93.2%. Factors associated with indirect decompression failure included low bone mineral density (T-score < 2.1), low reducible disc height (<13%), low postoperative disc height (< 10 mm), high-grade cage subsidence, and use of plate fixation. Conclusion: We proposed patient selection criteria for indirect decompression with LLIF which had a satisfactory success rate and identified factors associated with the need for additional direct decompression. Our proposed criteria may assist selection of patients likely to achieve good results following indirect decompression with LLIF, and optimize selection based on risk factors of failure.

Background: Although intravenous (i.v.) lidocaine is used as a perioperative analgesic in abdominal surgery, evidence of efficacy is limited. The infusion dose and duration remain unclear. This study aimed to investigate the effect of a longer low-dose 48-hour infusion regimen on these outcomes. Methods: Fifty-eight adults undergoing elective open colorectal surgery were randomized into the lidocaine group (1.5 mg/kg bolus followed by 1 mg/kg/h infusion for 48 hours) and control group. After surgery, patients were given a fentanyl patient-controlled analgesia machine and time to first bowel movement (primary outcome) and flatus were recorded. Postoperative pain scores and fentanyl consumption were assessed for 72 hours. Results: There was no significant difference in time to first bowel movement (80.1 ± 42.2 vs. 82.5 ± 40.4 hours; P = 0.830), time to first flatus (64.7 ± 38.5 vs. 70.0 ± 31.2 hours; P = 0.568), length of hospital stay (9 [8–13] vs. 11 [9–14) days; P = 0.531], nor postoperative pain scores in the lidocaine vs. control groups. Cumulative opioid consumption was significantly lower in the lidocaine vs. the control group from 24 hours onwards. At 72 hours, cumulative opioid consumption (μg fentanyl) in the lidocaine group (1,570 [825–3,587]) was over 40% lower than in the placebo group (2,730 [1,778–5,327]; P = 0.039). Conclusions: A 48-hour low-dose i.v. lidocaine infusion does not significantly speed the return of bowel function in patients undergoing elective open colorectal surgery. It was associated with reduced postoperative opioid consumption, but not with earlier hospital discharge, or lower pain scores.

Objective: Advances in ovarian cancer cytoreductive surgery have enabled more extensive procedures to achieve maximal cytoreduction but with a consequent increase in postoperative morbidity and mortality. The aim of this study was to evaluate factors for postoperative morbidity after extensive cytoreductive surgery for primary epithelial ovarian cancer (EOC), particularly those which may be modifiable. Methods: Electronic databases were searched. Meta-analysis was conducted using random- effects models. Results: Fifteen relevant studies, involving 15,325 ovarian cancer patients, were included in this review. Severe 30-day postoperative complications occurred in 2,357 (15.4%) patients. The postoperative mortality rate was 1.92%. Meta-analysis demonstrated that patient with following risk factors; age (p<0.001), Eastern Cooperative Oncology Group score >0 (p=0.001), albumin level <3.5 g/dL (p<0.001), presence of ascites on CT scan (p=0.013), stage IV disease (p<0.001) and extensive surgical procedure (p<0.001) has a significantly increase risk of developing postoperative complications. Surgical procedures including peritonectomy (p=0.012), splenectomy (p<0.001) and colon surgery (p<0.001) were significant predictors for postoperative complications. Moreover, we found that patients who received neoadjuvant chemotherapy followed by interval debulking surgery (NACT-IDS) had a lower risk of developing severe complications compared to those who underwent primary debulking surgery (PDS) (p<0.001). Conclusion: Our study demonstrated that patient performance status and hypoalbuminemia were the only significant adjustable preoperative risk factors associated with postoperative complications. Patients who underwent NACT-IDS had a lower risk of developing severe complications compared to PDS.
