AI Article Synopsis
- A study was conducted to evaluate the effectiveness of early superficial temporal artery-middle cerebral artery (STA-MCA) double anastomoses in patients suffering from progressing stroke due to atherosclerotic blockages.
- Nine patients, primarily middle-aged men with occlusions, were examined after undergoing the procedure despite receiving maximum medical treatment.
- Results showed that the procedure was safe, led to significant neurological improvement, and is recommended for patients with specific blood flow ratios even in subacute stages.
Article Abstract
Background: We investigated the efficacy of early superficial temporal artery-middle cerebral artery (STA-MCA) double anastomoses for patients with progressing stroke due to atherosclerotic occlusion.
Materials And Methods: Nine consecutive patients who underwent early STA-MCA double anastomoses were enrolled. All patients presented with progressing stroke despite maximal medical treatment. Cerebral blood flow in 7 patients was analyzed by single-photon emission tomography. Clinical outcomes were investigated postoperatively, and we evaluated the utility of early STA-MCA double anastomoses.
Results: Nine patients in the present study included those with middle cerebral artery occlusion (n = 6) and internal carotid artery occlusion (n = 3). The mean age was 58.4 years. Subjects comprised 1 female (11.1%) and 8 males (88.9%). The cause was low perfusion ischemia due to atherosclerotic occlusion with a small infarct. The mean regional cerebral blood flow (rCBF) ratio in the middle cerebral artery territory compared to the normal side was 69.6 ± 5.3%. The duration from onset to surgery was 1-8 days (median, 3.11 days). All patients underwent early STA-MCA double anastomoses, and no reperfusion-induced hemorrhage occurred. All of them slowly achieved obvious remission compared to symptoms on admission and achieved a good functional outcome.
Conclusions: Early STA-MCA double anastomoses were safe and effective, and early revascularization resulted in rapid neurological improvement. We recommend this procedure for patients with progressive ischemia due to main trunk artery occlusion, when the rCBF flow ratio with the normal side was 70 ± 10%, even at the subacute stage.

Single versus double stapled anastomosis in natural orifice specimen extraction (NOSE) laparoscopic anterior resection.

Background: Laparoscopic anterior resection (LAR) with Natural Orifice Specimen Extraction (NOSE) has shown benefits such as reduced pain, fewer wound complications, and improved cosmesis. In colorectal anastomosis during NOSE, double staple anastomosis (DSA) and triple stapled technique (TSA) are common. However, a novel single stapled anastomosis (SSA) technique, utilising two laparoscopically placed purse strings and only four 5 mm ports, has emerged.

Background: There is limited data within the urologic literature regarding bowel complications and leak rates following surgery requiring ileocolic anastomoses such as right colon pouch (RCP) and continent cutaneous ileocecocystoplasty (CCIC). We aimed to establish ileocolic anastomotic leak rates in urologic reconstructive surgery and determine bowel-related complications following RCP and CCIC surgeries.
Methods: We reviewed adult patients who underwent RCP or CCIC (2010-2022), investigating patient characteristics, perioperative variables, and outcomes.
Anatomical variations of the marginal mandibular nerve.

Introduction: The Marginal Mandibular Nerve (MMN), despite being didactically described as being a unique branch of the other branches of the Facial Nerve, has in practice an abundant anatomical variation. Both in relation to its ramifications and the positioning of these in relation to the lower edge of the mandible, as well as its anastomoses along its path, play a fundamental role in the surgical strategy during the approach of this cervicofacial site, and can generate, as underestimated its characteristics, inadvertent injuries and motor consequences to the patient.
Objective: To analyze the types of anatomical variations of the MMN in relation to its position, ramification, and distance from reference points, as well as its incidence that could imply technical difficulties in surgery.

Carinoplasty can be divided into the one-stoma method, the montage method, the double-barrel method, and the Miyamoto method. The one-stoma method is usually performed with right upper sleeve lobectomy, and with an anastomosis of the intermediate trunk to a carina. On the other hand, in the montage method, the double-barrel method or the Miyamoto method, carina is completely resected and the trachea, left main bronchus and right bronchus are divided into three pieces.

Article Synopsis
- Abdominal cocoon is a rare condition that can lead to serious complications like intestinal rupture and fistulas, as seen in a 51-year-old man who experienced abdominal injuries from a traffic accident.
- The surgery revealed that his small intestine was encased in dense fibrous tissue, leading to complications that required intensive postoperative care, including ventilator support and drainage management.
- Despite the challenges of a delayed intestinal fistula occurring 10 days after surgery, comprehensive nursing strategies and treatments led to the successful healing of the incision, allowing the patient to eventually recover and reverse the stoma after 5 months.
