Background: This study reviews our use of laparoscopic versus open appendicectomy over the last decade to track the trends in their usage in a middle-income country.
Methods: A retrospective study was conducted on patients with intraoperative confirmed acute appendicitis from January 2013 to December 2019 at Grey's Hospital, Pietermaritzburg, South Africa.
Results: Eight hundred fifty-one cases of AA were included. 724 (85%) patients underwent open surgery; 435 (60%) via a midline incision and 194 (27%) via a local incision. 127 (15%) patients underwent laparoscopic appendicectomy. A significant rend was noted for an increasing proportion of surgery performed by laparoscopy compared to open surgery (p = 0.02). Patients who underwent open surgery compared to laparoscopy presented with greater peritonism (48.5% vs. 28%, p < 0.001), delay from symptom onset (3 vs. 2 days, p < 0.001), more frequently from rural areas (94% vs. 86%, p = 0.002) and with higher AAST scores (46.7% AAST ≥ 4, vs. 14.9%, p < 0.001). This former group had significantly greater morbidity (42% vs. 35%, p < 0.001) with higher Clavien-Dindo scores, were more likely to require ICU admission (8.3% vs. 2.3%, p < 0.001) and have longer hospital stay (4 days vs. 2 days, p < 0.001); no statistically significant difference in mortality was observed (1.1% vs. 0.8%, p = 0.75).
Conclusions: There has been a steady increase in the uptake of laparoscopic appendicectomy and decrease in open approaches in our centre. There is still a high rate of patients with advanced disease, and it is unlikely that this cohort will be suitable for laparoscopic surgery. If we hope to increase the uptake of laparoscopic surgery for acute appendicitis even further, we must focus on identifying patients with early and low-grade disease.

Percutaneous VT Ablation via RA-to-LV Access in Patients With Double Mechanical Valves: A Multicenter Registry.
JACC Clin Electrophysiol
January 2025
Section of Cardiac Pacing and Electrophysiology, Division of Cardiology, Cleveland Clinic, Cleveland, Ohio, USA.
Background: In patients with mechanical aortic and mitral valves requiring catheter ablation of ventricular tachycardia (VT), a technique for access from the right atrium (RA) to the left ventricle (LV) via puncture of the inferoseptal process of the LV was previously described in a single-center series.
Objectives: This study sought to report the multicenter experience of VT ablation using this novel LV access approach.
Methods: We assembled a multicenter registry of patients with double mechanical valves who underwent VT ablation with RA-to-LV access.
Looped Penrose Drainages of Acute Hand Infections in Vulnerable Populations.

Purpose: Acute hand infections (AHIs) remain a challenge for hand surgeons and represent a condition for which clinical outcomes are considerably affected by social barriers. We previously described the looped Penrose drainage technique, where a drain is sutured to itself in a loop and the outflow tract of egress is maintained, thus obviating the need for large incisions, wound closure, or repeat packing, thereby reducing the follow-up burden. In the face of escalating numbers of socioeconomically vulnerable patients, especially in urban settings, we aimed to characterize the clinical features and outcomes of this technique in an urban population of patients with AHI.

J Hand Surg Am
January 2025
Cooper University Hospital, Camden, NJ.
Purpose: Xylazine has been associated with necrotic soft tissue wounds that have placed a challenging burden on patients who inject drugs in the Philadelphia region's health care system over the last few years. An analysis of our initial experience is being presented to guide future treatment and directions for future research.
Methods: A retrospective review of 55 patients with patient-reported xylazine use and associated upper-extremity wounds at a single institution was performed.

Purpose: This study aimed to evaluate the long-term efficacy of the ligation of the intersphincteric fistula tract (LIFT) procedure in treating high transsphincteric fistulas.
Methods: We conducted a retrospective study to evaluate the success rate of LIFT treatment in 82 patients with high transsphincteric fistulas involving at least 1/3 of the external sphincter. This study was carried out across 2 centers from November 2009 to February 2023.
Impact of orthognathic surgery on the cheek area using the Barcelona line.

A facial appearance of premature aging due to poor bone support of the soft tissues is frequently found in patients with midface hypoplasia. This study was performed to evaluate the changes in the soft tissues of the cheek area in patients subjected to bimaxillary orthognathic surgery. The cheek line angle and length of 27 consecutive patients who underwent bimaxillary surgery, were measured on cone beam computed tomography scans obtained before surgery and at 1 and 12 months after surgery using 3D software.
