Background: Laparoscopic sleeve gastrectomy (LSG) causes significant postoperative pain, necessitating effective multimodal analgesia strategies. This study evaluated the efficacy of the external oblique intercostal block (EOIB) in this context. Methods: This prospective, randomized, controlled, single-blind study conducted between April and December 2023 included 60 patients who underwent LSG. Patients were divided into the EOIB (30 ml 0.25% bupivacaine/side) and control (no block) groups. The primary outcome was the cumulative intravenous morphine milligram equivalent (MME) consumption in the first 24 h postoperatively. Secondary outcomes included 12-h MME consumption, pain scores, intraoperative remifentanil use, rescue analgesia requirements, time to first analgesic request, nausea/vomiting scores, antiemetic use, and American Pain Society Patient Outcome Questionnaire-Revised Turkish Version (APS-POQ-R-TR) scores. Results: The control group had significantly higher median opioid consumption than the EOIB group at 12 (14.4 vs. 5.8 mg; P < 0.001) and 24 h (25.9 vs. 10.6 mg; P < 0.001) postoperatively. The need for rescue analgesics did not differ significantly (43.3 vs. 23.3%; P = 0.1). The EOIB group exhibited significantly higher patient satisfaction (APS-POQ-R-TR score 2.91 vs. 4.42; P < 0.001) and consistently lower pain scores across all time points (P < 0.001). The EOIB group had lower nausea/vomiting scores (P < 0.001), fewer patients requiring antiemetics (16.7% vs. 40%; P = 0.045), longer time to first morphine request (57.5 vs. 25 min; P < 0.001), and lower remifentanil use (850 vs. 1050 μg; P < 0.001). Conclusions The preoperative EOIB, as a part of multimodal analgesia, provides effective analgesia for acute pain in patients undergoing LSG.

Purpose: With a focus on dislocation rates, this study aims to compare the posterior or posterolateral approach (PLA) with the piriformis-sparing approach (PSA) in elderly patients undergoing cementless hemiarthroplasty for displaced femoral neck fractures. Materials and Methods: This retrospective study included 194 patients who met the eligibility criteria and underwent surgery using the PLA (n=140) or the PSA (n=54). Patient data were reviewed for age, sex, body mass index, postoperative dislocation rate, presence of neurological conditions or other comorbidities, surgical duration, length of hospital stay, follow-up period, infection rate, admission to the intensive care unit (ICU), and mortality rate. Results: In Group 1 (PLA), 12 out of 140 patients (8.6%) experienced dislocation within a postoperative period of 1 to 5 years. Dislocations occurred in three out of 54 patients (5.6%) in Group 2 (PSA). Although the difference was not statistically significant (P=0.565), a significant difference was observed between the groups in terms of mortality (P=0.015) and surgical duration (P=0.0001). Conclusion In terms of functional outcomes and postoperative pain management, the advantages of modified PLA have been highlighted in recent studies. Although no statistically significant difference was found in this study, a 3% lower dislocation rate was demonstrated by the PSA as compared to the PLA.

The effects of electromagnetic field on distraction osteogenesis and new bony tissue were investigated. Twenty-five New Zealand rabbits were divided into an experimental (12 rabbits) and a control (13 rabbits) group. An osteotomy was performed on the right tibia in the diaphyseal region in both groups. The experimental group was exposed to a magnetic field of 50 Hz 1.0 mT for 3 hours a day for 13 weeks. The control group was kept in a similar environment but with no electromagnetic field. The distraction was continued until an increase of 10 mm was achieved. At weeks 4, 8, and 13, radiography, scintigraphy, and a biopsy were performed in both groups, and the results were statistically analyzed. The X-ray results were similar in both groups at all times. On the other hand while the scintigraphic and histopathological results were similar at weeks 4 and 13 in both groups, the osteoblastic activity was significantly greater in the experimental group at week 8 (p < 0.01). In conclusion an electromagnetic field increases the osteoblastic activity and osteogenesis, but has little effect during the remodeling phase.
