Involvement of the genicular branches in cystic adventitial disease of the popliteal artery as a possible marker of unfavourable early clinical outcome: a case report

<p>Abstract</p> <p>Introduction</p> <p>Cystic adventitial disease of the popliteal artery is a rare cause of non-atheromatous claudication. It usually requires surgery to improve the distance walked by patients.</p> <p>Case presentation</p> <p>We report the case of a 44-year-old Caucasian man with unilateral symptomatic popliteal cysts extending to his genicular branches and associated with multilevel stenosis of his anterior tibial artery. A surgical evacuation of the cysts successfully restored his arterial patency and led to an objective haemodynamic improvement but was associated with early recurrence of symptoms.</p> <p>Conclusion</p> <p>We suggest that the involvement of the genicular branches in cystic adventitial disease of the popliteal artery is a possible indicator of extensive adventitial degeneration and unfavourable clinical prognosis.</p

Ileo-colic intussusception: a rare cause of intestinal obstruction in adults

Adult intussusception is a rare cause of intestinal obstruction characterized by the telescoping of one segment of the intestine into another. Unlike in children, adult intussusception accounts for a small proportion of intestinal obstructions and is usually associated with an identifiable cause, such as malignancy or polyps. We present a case of ileo-colic intussusception in an elderly female, confirmed on abdominal computed tomography (CT) imaging, and successfully treated with emergency laparotomy and segmental bowel resection. Histology identified a benign lipomatous polyp as the lead point for the intussusception. This case demonstrates that adult bowel intussusception presents with non-specific symptoms, and early detection through abdominal CT imaging is crucial. Surgeons should be aware of the potential association with underlying malignancy, particularly in elderly patients, and therefore segmental resection should follow strict oncological principles

Paraureteric space post-ureteric re-implantation: a rare cause of small bowel obstruction

A female patient in her 80s presented with a 2-day history of abdominal pain and absolute constipation, having previously undergone a robotic left distal ureterectomy with ureteric re-implantation. CT revealed a closed-loop small bowel obstruction with transition point adjacent to the left ureter and resultant upstream hydronephrosis. An emergency laparotomy revealed small bowel herniation into a paraureteric space created by her previous surgery and defined by the distal ureter medially, the common iliac vessels laterally and the mobilised bladder dome anteriorly. The viable small bowel was reduced, and the space was eliminated by omental flap transposition after omentoplasty. The patient made a full recovery. Preoperative diagnosis of such an unusual cause of internal herniation can be challenging. This very rarely reported case raises awareness of the condition and proposes a treatment strategy.</jats:p

Endoscopic management of iatrogenic perforations during endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) for colorectal polyps: a case series

Background: Iatrogenic perforation during therapeutic colonoscopy, reported in up to 1% of endoscopic mucosal resections (EMRs) and up to 14% of endoscopic submucosal dissections (ESDs), has conventionally been an indication for surgery. Aims: We present a case series of successful endoscopic management of iatrogenic colorectal perforation during EMR and ESD, demonstrating the feasibility and safety of the method. Methods: Retrospective analysis of a database of patients undergoing EMR and ESD for colorectal polyps in a tertiary referral centre in the United Kingdom. Results: Four cases of perforation were identified (two EMRs and two ESDs) in a series of 218 procedures (1.8%), all detected at the time of endoscopy and managed with endoscopic clips. Patients were observed in hospital and treated with antibiotics. Their median length of stay was 3 days (range 2–6 days), with no mortality or need for surgery. Conclusion: Surgery is no longer the first choice in the management of iatrogenic perforations during EMR and ESD for colorectal polyps; in selected patients with small perforations and minimal extraluminal contamination, conservative management with application of endoscopic clips, antibiotics and close patient monitoring constitute a safe and effective treatment option, avoiding the morbidity of major surgery

Colonic stenting for colorectal cancer: stoma avoidance with acceptable radiation exposure

Background/Aims Self-expanding metal stents (SEMS) are used to manage colonic obstruction for palliative decompression or as a bridge to curative surgery and are typically placed under fluoroscopic guidance. This study aimed to quantify the radiation exposure associated with colonic stenting for obstructing colorectal cancer (CRC) and compare it with established diagnostic reference levels (DRLs) for similar fluoroscopy-guided procedures. Secondary outcomes included procedural success rates, stent patency, stoma rates, and complications. Methods This retrospective observational study was conducted at a single district general hospital and included all the patients who underwent colonic stenting for CRC between March 2016 and February 2021. Radiation exposure was measured using the kerma-area product (KAP) in µGy*m² and fluoroscopy time in minutes, obtained from existing electronic patient records. Results Fifty-two stenting procedures were performed in 47 patients. Median KAP was 1,373.7 (interquartile range [IQR], 584.4–3,185.2) µGy*m², and fluoroscopy time was 8.9 (IQR, 4.4–12.6) minutes. Technical and clinical success was achieved in 86.5% of the cases. In palliative cases, 88.9% of patients maintained stent patency until death. The complications included perforation (5.8%) and stent migration (3.9%). Laparoscopic surgery was performed in 70% of curative cases. Conclusions Radiation exposure during colonic stenting is within acceptable ranges and comparable to that of other fluoroscopy-guided procedures. These findings support the listing of colonic stenting in future National DRLs in the United Kingdom
