A rare case of percutaneous endoscopic gastrostomy causing a small bowel obstruction and subsequent bowel erosion

Abstract

Gastrostomy tubes can be used to provide long-term nutrition and feeding when oral intake is not adequate. A rare but serious complication includes iatrogenic small bowel injury. The incidence of this is infrequent due to its position of the small bowel beneath the omentum, however, injury leading to obstruction and volvulus has been previously described in the literature. We present an unusual case of gastrostomy tube transection into omental fat causing a kink in the small bowel allowing for a transition point of obstruction and subsequent erosion of the gastrostomy tube into the small bowel.

Successful use of adipose-derived mesenchymal stem cells to correct a male breast affected by Poland Syndrome: a case report

Abstract

Poland syndrome is a rare congenital anomaly in which affected persons are born with missing or underdeveloped muscles on one side of the body. In this case study we present the case of a 28-year-old male with absence of all middle phalanges of the right hand and other rare anomalies, who underwent reconstruction with a new method that combines a mixture of adipose-derived mesenchymal stem cells and fat transfer. The patient's restoration of the pectoralis area was aesthetically successful with no complications and remained unchanged even after 3.5 years. The proposed method represents an interesting reconstructive approach for treating Poland's syndrome deformities.

Repair of gastrocutaneous fistula utilizing thickened fluids: application of Poiseuille’s Law to fistula healing

Abstract

Enterocutaneous fistulas are a rare occurrence after placement of a PEG tube. The key risk factor for their development is the time the PEG tube is in situ, giving time for the fistula tract to mature. Enterocutaneous fistulae are traditionally treated with parenteral nutrition or surgical management. We present a case of a 69-year-old woman who underwent surgical closure of an enterocutaneous fistula with a fibrin plug. The fistula recurred on post-operative Day 5, and the patient was placed on thickened fluids to increase the viscosity of the fluid exiting the fistula tract. This approach decreased the output and lead to subsequent closure of the fistula by outpatient follow up at 4 weeks. This case demonstrates an application of Poiseuille's law to closure of fistula tracts.

Education in neuroanesthesia and neurocritical care: trends, challenges and advancements

Purpose of review We summarize the latest evidence in neuroanesthesia and neurocritical care (NCC) training. In addition, we describe the newer advancements that clinical educators face in these subspecialties. Lastly, we highlight educational approaches that may lead to an enhanced learning experience and development of necessary skills for neurosciences trainees. Recent findings Current neuroanesthesia and NCC training requires acquisition of specific skills for increasing complex surgical cases, specialized neurosurgical practice and new perioperative technologies. Furthermore, there is increasing international interest for standardization and accreditation of neuroanesthesia fellowship programs. Recent evidence has demonstrated that well structured training using high-fidelity simulation improves cognitive and technical skills in acute neurological crises. Summary High-fidelity simulation in perioperative care of neurosurgical patients can be part of formal neuroanesthesia and NCC curricula, and potentially impact trainees' proficiency. A research agenda is needed to validate the assessment of most effective educational interventions in neurosciences trainees with diverse medical backgrounds. Creative combinations of cost-effective interventions including traditional teaching, specific technical skills workshops, low and high-fidelity simulation deserve to be assessed in future studies.

Anesthesia for awake craniotomy

Purpose of review The current review reports on current trends in the anesthetic management of awake craniotomy, including preoperative preparation, sedation schemes, pain management, and prevention of intraoperative complications. Recent findings Both approaches for anesthesia for awake craniotomy, asleep–awake–asleep and monitored anesthesia care (MAC), have shown equal efficacy for performing intraoperative brain mapping. Choice of the appropriate scheme is currently based mainly on the preferences of the particular anesthesiologist. Dexmedetomidine has demonstrated high efficacy and safety in MAC for awake craniotomy and has become a rational alternative to propofol. Despite the high efficacy of scalp block and opioids, pain remains a common compliant in awake craniotomy. Appropriate surgical tactics can reduce pain and even prevent postoperative neurological complications. Although the efficacy of prophylaxis of intraoperative seizures with anticonvulsants remains doubtful, levetiracetam can be superior to other drugs for this purpose. Summary Following a great deal of progress in anesthetic management, awake craniotomy, which had been a relatively rare approach, is now a commonly performed procedure for neurosurgical intervention. Modern anesthesia techniques can provide for successful brain mapping in almost any patient. Management of awake craniotomy in high-risk patients is a central task for future research.

Opioid-free anesthesia: a different regard to anesthesia practice

Purpose of review In the past two decades, opioids have been prescribed increasingly for the treatment of various chronic pain conditions and during the perioperative period. Perioperative opioid administration is associated with well known adverse effects and recently to long-term use and poor surgical outcomes. In this context, the anesthesiologists have to face their responsibilities. The review discusses the neurophysiological basis of opioid-free anesthesia (OFA), the rational supporting its use in perioperative medicine as well as barriers and future challenges in the field. Recent findings OFA has gained in popularity as a way to enhance early recovery and to spare opioids for the postoperative period. Whether it is possible to deliver safe and stable anesthesia without intraoperative opioids to many patients undergoing various surgical procedures, OFA still raises questions. Accurate monitoring to measure intraoperative nociception and guide the use of adjuvants are not available. There is a need for the development of procedure-specific strategies as well as indications and contraindications to the technique. Finally, objective assessment of OFA use on patient outcomes should be recorded in large multicenter studies. Summary OFA stands as a new paradigm, which questions anesthesiology practice and might help to rationalize perioperative opioids use.

Genetics and genomics in postoperative pain and analgesia

Purpose of review The review describes recent advances in genetics and genomics of postoperative pain, the association between genetic variants and the efficacy of analgesics, and the role of pharmacogenomics in the selection of appropriate analgesic treatments for postoperative pain. Recent findings Recent genetic studies have reported associations of genetic variants in catechol-O-methyltransferase (COMT), brain-derived neurotrophic factor (BDNF), voltage-gated channel alpha subunit 11 (SCN11A) and μ-opioid receptor (OPRM1) genes with postoperative pain. The recent pharmacogenetics studies revealed an association of the organic cation transporter 1 (OCT1) and ATP-binding cassette C3 (ABCC3) polymorphisms with morphine-related adverse effects, an effect of polymorphisms in cytochrome P450 gene CYP2D6 on the analgesic efficacy of tramadol and no effect of CYP2C8 and CYP2C9 variants on efficacy of piroxicam. Summary Genetic variants associate with inter-individual variability in drug responses and they can affect pain sensitivity and intensity of postoperative pain. Despite the recent progress in genetics and genomics of postoperative pain, it is still not possible to precisely predict the patients who are genetically predisposed to have severe postoperative pain or who develop chronic postoperative pain.
