Peritoneal encapsulation - An unusual cause of acute bowel obstruction: A case report.

INTRODUCTION/IMPORTANCE: Peritoneal encapsulation (PE) is a rare congenital anomaly characterised by the presence of an accessory peritoneal membrane which encases part of the small bowel. Typically, this remains asymptomatic, however; in rare cases, a person may present with symptoms suggestive of a small bowel obstruction. CASE PRESENTATION: Here we present a case of a 58 year old gentleman with congenital PE causing a bowel obstruction which was revealed on commuted tomography scan. He required a laparotomy and excision of the accessory sac. CLINICAL DISCUSSION: Pre-operative diagnosis of PE can be challenging. It can present as a bowel obstruction with unique features including asymmetric distension of the abdomen on clinical exam and cocoon-like cluster of small bowel on imaging. CONCLUSION: Congenital PE is a rare cause of bowel obstruction and should be considered early in patients presenting with symptoms of bowel obstruction without previous abdominal surgery.

Torsion of Meckel's diverticulum-a case report and literature review.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. Torsion is a rare complication of MD with only 48 cases described in the English literature to date. We describe a case of a 22-year-old male who presented to the emergency department with lower abdominal pain. Pre-operative computed tomography scan suggested a torted MD. This was confirmed on diagnostic laparoscopy and managed with segmental resection of the MD and a concurrent appendicectomy. Histopathology confirmed torsion of MD and a normal appendix. The patient recovered well without any complications. Torsion occurs invariably with giant MD defined as a length of >5 cm. Surgical options for MD include diverticulectomy, wedge resection and segmental resection via laparoscopic or open approach. The rate of pre-operative diagnosis remains low but with advances in imaging and awareness of this condition, this is likely to increase with time.

Electrochemical performance of l-tryptophanium picrate as an efficient electrode material for supercapacitor application.

A new, prominently stable organic material, l-tryptophanium picrate, was synthesized via a one-step process. The as-prepared sample was characterized by UV-visible, FT-IR, Raman, TGA-DSC, XRD, FE-SEM, EDX, 1H-NMR, 13C-NMR and GC-MS. The significant capacitive behaviour of l-tryptophanium picrate was investigated by cyclic voltammetric studies (CV), galvanostatic charge-discharge tests and impedance spectroscopy techniques in 1 M aqueous KOH. The newly fabricated l-tryptophanium picrate electrode material exhibited an excellent specific capacitance of 263 F g-1 at a current density of 1 A g-1. Furthermore, it exhibited a capacitance retention of about 92% even after 2000 consecutive charge/discharge cycles. Moreover, the as-prepared electrode material illustrated electrochemically reversible behaviour. In addition, the synthesized material showed good electrochemical performance under the selected potential window. Thus, the fabricated electrode was proved to be a promising alternate electrode for high performance energy storage applications.
