OBJECTIVE: To analyze the amount of blood loss at different stages of Posterior Instrumented Spinal Fusion (PSF) surgery in adolescent idiopathic scoliosis (AIS) patients.
SUMMARY OF BACKGROUND DATA: Knowing the pattern of blood loss at different surgical stages may enable the surgical team to formulate a management strategy to reduce intraoperative blood loss.
METHODS: One hundred AIS patients who underwent PSF from January 2013 to December 2014 were recruited. The operation was divided into six stages; stage 1-exposure, stage 2-screw insertion, stage 3-release, stage 4-correction, stage 5-corticotomies and bone grafting, and stage 6-closure. The duration and blood loss at each stage was documented. The following values were calculated: total blood loss, blood loss per estimated blood volume, blood loss per minute, blood loss per vertebral level fused, and blood loss per minute per vertebral level fused.
RESULTS: There were 89 females and 11 males. The mean age was 17.0 ± 5.8 years old. Majority (50.0%) were Lenke 1 curve type. The mean preoperative major Cobb angle was 64.9 ± 15.0°. The mean number of levels fused was 9.5 ± 2.3 levels. The mean operating time was 188.5 ± 53.4 minutes with a mean total blood loss 951.0 ± 454.0 mLs. The highest mean blood loss occurred at stage 2 (301.0 ± 196.7 mL), followed by stage 4 (226.8 ± 171.2 mL) and stage 5 (161.5 ± 146.6 mL). The highest mean blood loss per minute was at stage 5 (17.1 ± 18.3 mL/min), followed by stage 3 (12.0 ± 10.8 mL/min). The highest mean blood loss per vertebral levels fused was at stage 2 (31.0 ± 17.7 mL/level), followed by stage 4 (23.9 ± 18.1 mL/level) and stage 5 (16.6 ± 13.3 mL/level).
CONCLUSION: All stages were significant contributors to the total blood loss except exposure (stage 1) and closure (stage 6). Blood loss per minute and blood loss per minute per level was highest during corticotomies (stage 5), followed by release (stage 3). However, the largest amount of total blood loss occurred during screw insertion (stage 2).
LEVEL OF EVIDENCE: 2.
OBJECTIVE: To evaluate the perioperative outcome of posterior spinal fusion in adolescent idiopathic scoliosis (AIS) patients comparing a single attending surgeon strategy (G1) versus a dual attending surgeon strategy (G2).
SUMMARY OF BACKGROUND DATA: The complication rate for surgical correction in AIS is significant. There are no prospective studies that investigate dual attending surgeon strategy for posterior spinal fusion in AIS.
METHODS: A total of 60 patients (30 patients in each arm) were recruited. The patients were comparable for age, gender, Lenke classification, major Cobb angle magnitude, and number of fusion levels. The anesthetic, surgical, and postoperative protocol was standardized. The outcome measures included the operative duration, blood loss, postoperative hemoglobin, need for transfusion, morphine usage, duration of hospital stay, intraoperative lactate levels, and pH. The timing of the operation at six critical stages of the operation was recorded.
RESULTS: The mean operative time for G2 was 173.6 ± 27.0 minutes versus 248.0 ± 49.9 minutes in G1 (P
MATERIALS AND METHODS: The secondary data analysis was conducted using the National Eye Database from 2007 to 2014. Demographic features, ocular comorbidities, technique of surgery, grade of surgeons, types of intraoperative complications, and reasons for not obtaining good visual acuity following intraoperative complications were studied. Statistics was done using Statistical Package for Social Sciences version 20.
RESULTS: Out of 12,992 eyes, 6.1% had intraoperative complications. The highest rate of complications was when more trainees (medical officers [MOs] and gazetting specialists) operated. Posterior capsule rupture (PCR) was the most common complication followed by vitreous loss and zonular dehiscence. Those aged below 40 years had more complications (P < 0.05), and females had more complications. Ethnicity did not affect complications. Pseudoexfoliation was the only comorbidity causing complications (P < 0.05). Phacolytic lenses had 8.118 times the odds of getting intraoperative complications. MOs and gazetting specialists got more complications. Good outcomes were obtained in cases without complications and those operated by specialists. High astigmatism was the main reason for poorer outcomes.
CONCLUSION: Intraoperative complications were caused mostly by less experienced doctors and had poorer outcomes. Age below 40 years, females, the presence of pseudoexfoliation and phacolytic lenses had more complications. PCR was the most common complication.
DESIGN: A retrospective study.
METHODS: Patients who underwent cataract surgery from January 2011 to December 2012 in a hospital in Malaysia were studied. The data were obtained from the National Eye Database of Malaysia.
RESULTS: Of 80.4% eyes (2519) that had undergone phacoemulsification, it was found that 3.06% (77) of the cases had PCR as one of the complications. The largest number of PCRs happened during cortical removal (35.2%), followed by segment removal (25.4%), cracking (8.5%), and aspiration of the oculoviscodevice (8.5%). It has been found that the rupture most often occurred during cortex removal by consultants, whereas most PCRs occurred during segment removal by specialists.
CONCLUSIONS: This study reveals that around 3% of patients had PCR during phacoemulsification. It is important to recognize PCR and presence of vitreous loss intraoperatively to prevent further complications of cystoid macular edema and endophthalmitis.
METHODS: Patients with mild to moderate ABP were prospectively randomized to either an early cholecystectomy versus a delayed cholecystectomy group. Recurrent biliary events, peri-operative complications, conversion rate, length of surgery and total hospital length of stay between the two groups were evaluated.
RESULTS: A total of 72 patients were enrolled at a single public hospital. Of them, 38 were randomized to the early group and 34 patients to the delayed group. There were no differences regarding peri-operative complications (7.78% vs 11.76%; p = 0.700), conversion rate to open surgery (10.53% vs 11.76%; p = 1.000) and duration of surgery performed (80 vs 85 minutes, p = 0.752). Nevertheless, a greater rate of recurrent biliary events was found in the delayed group (44.12% vs 0%; p ≤ 0.0001) and the hospital length of stay was longer in the delayed group (9 vs 8 days, p = 0.002).
CONCLUSION: In mild to moderate ABP, early laparoscopic cholecystectomy reduces the risk of recurrent biliary events without an increase in operative difficulty or perioperative morbidity.
METHODS: Fifty-five patients with achalasia cardia who underwent laparoscopic Heller myotomy between 2010 and 2019 were enrolled. The adverse events and clinical outcomes were analyzed. Overall patient satisfaction was also reviewed.
RESULTS: The mean operative time was 144.1 ± 38.33 min with no conversions to open surgery in this series. Intraoperative adverse events occurred in 7 (12.7%) patients including oesophageal mucosal perforation (n = 4), superficial liver injury (n = 1), minor bleeding from gastro-oesophageal fat pad (n = 1) & aspiration during induction requiring bronchoscopy (n = 1). Mean time to normal diet intake was 3.2 ± 2.20 days. Mean postoperative stay was 4.9 ± 4.30 days and majority of patients (n = 46; 83.6%) returned to normal daily activities within 2 weeks after surgery. The mean follow-up duration was 18.8 ± 13.56 months. Overall, clinical success (Eckardt ≤ 3) was achieved in all 55 (100%) patients, with significant improvements observed in all elements of the Eckardt score. Thirty-seven (67.3%) patients had complete resolution of dysphagia while the remaining 18 (32.7%) patients had some occasional dysphagia that was tolerable and did not require re-intervention. Nevertheless, all patients reported either very satisfied or satisfied and would recommend the procedure to another person.
CONCLUSIONS: Laparoscopic Heller myotomy and anterior Dor is both safe and effective as a definitive treatment for treating achalasia cardia. It does have a low rate of oesophageal perforation but overall has a high degree of patient satisfaction with minimal complications.
