Medical devices in the abdomen and pelvis
Dr Henry Knipe and Dr Praveen Jha et al.
Medical devices in the abdomen and pelvis are important to be recognized, just like medical devices of the chest. Many-a-times we tend to ignore these devices, considering they are non-pathological, however it is essential to know malpositioning or interventional mishaps.
Gastrointestinal tubes
- stomach tubes - nasogastric / Ryle's tube, feeding tube.
- intestinal tubes - Millor-Abbot tube (not used now), enteroclysis tube
- gastrostomy tube(s)
- jejunostomy tube(s)
- gastric lap bands
Genitourinary devices
- ureteral stents - double 'J' stent. Ureteral stents can perforate the genitourinary tract, cause severe bleeding, may cause infection or can station a calculus around it.
- urethral stent
- bladder neck stent
- artificial urinary sphincters
- Foley's catheters
- nephrostomy tube - angiographic catheters, pigtail catheter, Malecot's catheter
- contraceptive devices - IUCD (Copper-T, Mirena), Norplant, vaginal ring
- tubal ligation devices
- vasectomy devices
- pessaries
- penile prostheses
- tandem and ovoid implants for gynecologic brachytherapy
- residual Thorotrast deposits (not used now, but may be encountered in older patients)
Post-operative devices
- surgical sutures, staples, clips, and glue
- surgical sponges -
- most common retained surgical foreign body is laparotomy cotton sponge
- it can be easily identified on radiographs by a 'ribbon-like' characteristic marker - see 'gossypiboma'
- surgical needles, ties
- surgical drains - closed-wound suction drains, gravity drains, sump drains
- biliary drains and stents - T-tube, biliary stent (e.g. Cook's stent)
- metallic stents - vascular stents, self-expandable metallic stent (SEMS)
- embolization coils
- IVC filters
- vascular grafts e.g. aortoiliac bypass grafts
Miscellaneous
- foreign bodies
- medications ingested by patient - potassium chloride, Pepto-Bismol, iron tablets, vitamin pills, barium and iodinated contrasts
- patient restraint devices
- colostomy bags
- bowel biopsy devices
- fetal monitoring equipment
- residual contrast
- vertebral fixation screws
- vertebroplasty related
- hernia mesh - Tantalum mesh
- umbilical arterial and venous catheters
- dialysis catheter
- ascites drain
- infusion pumps
- insulin pumps
- femoral central venous catheters
- ECMO arterial or venous catheters
- ventriculoperitoneal catheters
