Background: Laparoscopic approach is the gold standard for surgical treatment of morbid obesity. The single-port (SP) approach has been demonstrated to be a safe and effective technique for the treatment of morbid obesity in several case control studies.
Objectives: Compare conventional multiport laparoscopy (LAP) with an SP approach for the treatment of morbid obesity using sleeve gastrectomy in terms of postoperative pain using a visual analog scale (VAS) 0-100, surgical outcome, weight loss, and aesthetical satisfaction at 6 months after surgery.
Setting: University Hospital, Spain.
Methods: Randomized, controlled pilot study. The trial enrolled patients suitable for bariatric surgery, with a body mass index lower than 50 kg/m and xiphoumbilical distance lower than 25 cm. Patients were randomly assigned to receive LAP or SP sleeve gastrectomy.
Results: A total of 30 patients were enrolled; 15 were assigned to LAP group and 15 to SP group. No patients were lost during follow-up. Baseline characteristics were similar in both groups. A significantly higher level of pain during movement was noted for the patients in the LAP group on the first (mean VAS 49.3±12.2 versus 34.1±8.9, P = .046) and second days (mean VAS 35.9±10.2 versus 22.1±7.9, P = .044) but not the third day (mean VAS 20.1±5.2 versus 34.12.9 ±4.3, P = .620). No differences regarding pain at rest, operative time, complications, or weight loss at 6 months were observed. Higher aesthetical satisfaction was noticed in SP group.
Conclusions: In selected patients, SP surgery presented less postoperative pain in sleeve gastrectomy compared with the conventional laparoscopic approach with similar surgical results.

Primary hepatic carcinosarcoma: a case report with insights from retrospective analysis of clinical characteristics and prognostic factors.

Primary hepatic carcinosarcoma (HCS) is an extremely rare malignant tumor with carcinomatous and sarcomatous elements. Few reported cases of HCS exist, especially with sufficient records to describe imaging and pathological features, making the diagnosis, treatment, and prognosis of HCS a significant challenge for physicians. Here, we report a case of HCS with spontaneous rupture as the initial symptom in a 77-year-old elderly male who was admitted with right upper abdominal pain for 8 days.

Purpose: While esketamine shows promise as an adjunct in procedural sedation, its impact on postoperative cognitive recovery remains incompletely characterized. This study investigated the effects of esketamine on multiple dimensions of recovery, particularly cognition, in patients undergoing colonoscopy with propofol-based sedation.
Patients And Methods: We conducted this randomized, double-blinded, placebo-controlled trial from January 6, 2023, to May 20, 2024, at two hospitals in China.

Objective: To evaluate the efficacy of supra-inguinal fascia iliaca compartment block (S-FICB) in patients undergoing proximal femoral nail antirotation (PFNA) internal fixation surgery for intertrochanteric fracture (ITF).
Methods: Retrospective analysis of 95 patients with ITF undergoing PFNA internal fixation surgery in the First People's Hospital of Yong Kang from March 2021 to August 2023 was performed. Among them, 49 patients received general anesthesia (GA; GA group) and 46 patients received S-FICB combined with general anesthesia (S-FICB group).
Tranexamic acid use in rotator cuff repair: A systematic review of perioperative outcomes.

Background: Tranexamic acid (TXA) use has become the gold standard in total joint arthroplasty to limit intraoperative blood loss and transfusion rates. More recently, the indications for TXA have expanded to knee and shoulder arthroscopy with promising early results. However, the effectiveness of TXA during arthroscopic rotator cuff repair (RCR) is unclear.

Purpose: Arthroscopic rotator cuff repair (ARCR) commonly results in significant postoperative pain. Adjuncts like dexamethasone (DEX) and tranexamic acid (TXA) are used to enhance postoperative recovery. This study aimed to determine whether the combined application of TXA and DEX could improve postoperative recovery during the first 24 hours in ARCR patients.
