Complications during laparoscopic surgery Bethlehem 160312 Anton Langebrekke Oslo University Hospital Oslo Norway Operative endoscopy Out-patient procedure Complications of laparoscopic surgery physical and emotional suffering for patients relatives doctors financial legal costs proceedings Endoscopic surgery Risk to operator Electric choc Skin and corneal burns Loss of laparoscopic privilegies Loss of patients and referrals Malpractic litigation Norway 1992-1993 2 deaths due to perforation of retroperitoneal vessels (Common iliac artery) Can all surgeons do advanced laparoscopic surgery? Probably not: Few cases available Surgical volume is decreasing Few training programs are advanced Complications of laparoscopic surgery Prevention Identify high-risk patients Properly maintained equipment Continous training Knowledge of your instruments The laparoscopic team work (anesthesianurses-surgeon) Training Certification Credentialing Training, training, training… ….. Complications of laparoscopic surgery 1 of 4 gynecologists have at least 1 case of Veress or trocar injury. Half of these injuries required laparotomy. Complications of laparoscopic surgery 256 complications from 70607 laparoscopies (3.6/1000) between 90-94 Harkki-Siren & Kurki jan 1997. A nationwide analysis of laparoscopic complications 1997 Complications of laparoscopic surgery 145 complications from 25764 laparoscopies (5.7/1000) 3.3/1000 severe complications. 2 fatalities, 38 epigastric haemorrhage (1.47/1000) 29 gastro-intestinal damage (1.13/1000) 27 intraabd. vessels (1.05/1000) >50% of lesions from laparoscopic entry Jansen et al. Prospective multi-centre study of 72 hospitals in the Netherlands. British J Obstet Gynecol 1997;104:595-6. Complications of laparoscopic surgery Overall incidence of penetrating injury: 2,7/1000 patients Philips, Keith, Hulka. J Reprod Med 1986 Complications of laparoscopic surgery Example: during 1984 in the UK: 124548 gynecological laparoscopies. We would expect 300-500 serious complications each year. Or in the US: 5000 serious complications each year. Complications of laparoscopic surgery Most experienced laparoscopist have their own “perfect” laparoscopic method of entry. No need to change, it will probably not occur (< 4/1000 severe complications) This comfortable feeling is not shared by medical experts in malpractice cases Complications of laparoscopic surgery 1. Anesthesia related 2. Veress needle and trocar insertions 3. Pneumoperitoneum 4. Surgical injury 5. Closure Complications of laparoscopic surgery Insertion techniques: classical approach direct insertion without Veress open laparoscopy gasless laparoscopy insertion under direct vision Umbilical incision Low pressure entry High pressure entry Vascular perforation- Aorta Complications of laparoscopic surgery Trocar insertion Sharp trocar? (less force) New bladeless more safe Second trocar always under direct vision Complications of laparoscopic surgery 3. Pneumoperitoneum 1. Emphysema (subcut/preperit/omental) 2. Pneumothorax 3. Pneumomediastinum 4. Gas embolism (more freq. with air) 5. Failure to maintain pneumoperitoneum 6. Cardiac arrhytmias (bradycardia) 7. Hypercarbia Complications of laparoscopic surgery Complications associated with laparoscopic entry include: failure to gain access to the abd. cavity damage to a major retro-peritoneal blood vessel damage to the gastro-intestinal tract damage to vessels of the abdominal wall post-laparoscopic bowel herniation Open laparoscopy Buanes Open laparoscopy does not reduce the risk of major complications 2 university teams: classic (8324) versus open (1652) technique Conversion to laparotomy: significant higher in open group Risk of major complications is comparable in the 2 groups. (4 versus 3). 4: 1 aorta injury, 3 bowel injuries 3: 2 bowel inuries, 1 postoperative occlusion Chapron C. et al. Complications during ……. Acta Obstet Gynecol Scand 2003;82:1125-29. Complications of laparoscopic surgery 4. Surgical injury 1. 2. 3. 4. 5. 6. 7. 8. Thermal injury Dissection injury Inability to complete procedure Vascular injury Bowel injury Bladder/ureteral injury Nerve injury Lymphoedema/lymphocele Complications of laparoscopic surgery Vascular injuries Diagnosis Return of frank blood Bleeding may be concealed if confined to retroperitoneum (occult bleeding) Unexplained drop in blood pressure and or tachycardia Laparotomy must not be delayed if bleeding is suspected Complications of laparoscopic surgery Vascular injuries Treatment Epigastric/abd wall vessels: Coagulation Tamponade (Foley) Sutures Exploration/laparotomy Major vessel injury Immediate laparotomy in most cases Avoid movement of Veress needle Aortic compression Inspect post side of vessels (through-and through injury) Vascular misadventure Complications of laparoscopic surgery Vascular perforations How to avoid: technique and anatomy. Epigastric vessels most common Epigastric vessel Epigastric hematoma Hemostatic clips Internal iliac vein bleeding Complications of laparoscopic surgery Electrosurgery Prevention by careful technique. • Check insulation • Tip of instruments always visible • Cauterized area isolated • Bipolar whenever possible • Disposable is disposable Complications of laparoscopic surgery Electrosurgery Electrosurgical intestinal injuries: often apparent 4-10 days later Traumatic bowel perforations: symptoms within 12-48h. Complications of laparoscopic surgery Electrosurgery Soderstrom and Levy studied 12 cases of intestinal perforation (caused by monopolar) Detailed histology showed that 11/12 were mechanical trauma and not electrical burns Neddle/trocar perforation? Operative technical errors? Soderstrom RM Levy BS. Bowel injuries.... Cont Obstet Gynecol 1986;27:41 Complications of laparoscopic surgery Electrosurgery Early reports concerning complications of electrosurgery were largely exaggerated There were errors of technique not uncontrolled events Zucker et al. Am J Surg 1991;161:36 Complications of laparoscopic surgery Gastrointestinal injuries High risk: Previous abdominal surgery Previous abdominal radiotherapy Obese patients Consider open laparoscopy/ alternative entry site (Palmer) Incidence 1,0-2,7/1000 Chamberlain et al RCOG 1978 Yupze J Reprod Med 1990 Complications of laparoscopic surgery Gastrointestinal injuries Stay open to complications Friend with the surgeons In this way avoiding complications to complications Complications of laparoscopic surgery Gastrointestinal injuries Gastric perforation (oro/nasogastric tubing) Small/large bowel. Leave trocar in place Laparoscopic bowel repair Laparotomy Veress needle perforation: heals with antibiotics Urogenital Complications Bladder Peroperative: Gas in the Foley bag.! Blue dye in bladder if suspected Later perforation: uroplania Bladderperforation Urogenital Complications Ureter If suspected 5 ml Indigocarmin IV with 10 mg Furosemid Diagnosis in 10 minutes Cystoscopy can also be used Ureterlesion Uretertrauma during pelvic wall surgery Ureterwindow Complications of laparoscopic surgery 5. Closure Unrecognised bleeding (reduce pressure) Unrecognised visceral injury Abdominal wall injuries Infection Wound dehiscence herniation Complications of laparoscopic surgery Herniation into a trocar site Small bowel obstruction 3-7 days postop. Use small trocars whenever possible Evacuate all CO2 prior to removing sheat Remove under direct vision Closure of fascia if trocars >10-12 mm Postoperative ileus because of bowel incarceration It is very dangerous to be right on a subject on which the established authorities are wrong.
