Clinical overview
Minimally invasive surgery (MIS) — laparoscopy and hysteroscopy — has displaced laparotomy for most benign gynaecological operations because it reduces blood loss, pain, wound complications, adhesion formation and length of stay. But the trade-off is a distinctive, often iatrogenic complication profile that is largely preventable and largely front-loaded: most serious laparoscopic injuries happen at entry, before the operation has even begun, and most hysteroscopic disasters relate to the distension medium rather than the surgical target. The emphasis throughout is on the systems, techniques and checks that stop harm, not merely on listing the harms.
Prevention runs across the whole operative pathway: patient selection and preoperative optimisation; safe entry; energy and instrument discipline; recognition of vascular, visceral and urological injury; control of the distension/insufflation environment; and structured recovery. In the South African public setting these principles must be read against real constraints — variable laparoscopic stack availability, theatre lists dominated by emergency obstetrics, a high background of pelvic adhesive disease from sexually transmitted infection and prior caesarean, and a substantial HIV-positive surgical population. Prevention here is not abstract: a single recognised-and-repaired bowel injury is the difference between a one-week recovery and a death from delayed peritonitis. This chapter builds on the related technical objectives — Electrosurgery safety, Pneumoperitoneum, Operative hysteroscopy, Safe use of surgical instruments and ERAS principles — and should be read alongside them.

The complication map
Laparoscopic complications cluster predictably, and naming the cluster is half the prevention:
- Entry injuries — the single most dangerous category. Vascular injury (aorta, common iliac vessels, inferior epigastric vessels) and visceral injury (bowel, especially with adhesions to the umbilicus) occur at Veress needle or primary trocar insertion. Major vessel injury is rare but is the leading cause of laparoscopy-related death.
- Visceral injury — bowel, bladder, ureter. Thermal injury from electrosurgery is particularly dangerous because it presents late (typically 3–10 days postoperatively as delayed perforation), having looked benign at the time.
- Urological injury — bladder injury during dissection of the bladder flap or anterior compartment; ureteric injury at the pelvic side wall, infundibulopelvic ligament, uterine artery and uterosacral ligaments — the four classic danger zones.
- Insufflation-related — CO₂ embolism, subcutaneous emphysema, pneumothorax/pneumomediastinum, and the cardiorespiratory consequences of raised intra-abdominal pressure and steep Trendelenburg.
- Port-site complications — bleeding from the inferior epigastric vessels, port-site hernia (risk rises with fascial defects ≥10 mm), and port-site metastasis in malignancy.
- Hysteroscopic complications — uterine perforation, distension-fluid overload with dilutional hyponatraemia (the hysteroscopic equivalent of TURP syndrome), gas embolism, false passage, cervical trauma and infection.
Entry physiology and anatomy
The umbilicus is the standard entry point because the abdominal wall layers fuse there, but it sits only a few centimetres anterior to the aortic bifurcation and great vessels in a thin patient — hence the insistence on a 45° insertion angle and awareness of body habitus. Insufflation to an adequate pneumoperitoneum lifts the anterior wall away from the viscera and great vessels, which is why entry safety is intimately tied to confirming correct Veress placement before gas is delivered. The inferior epigastric vessels run lateral to the obliterated umbilical arteries and medial to the round ligament — lateral ports must be placed under direct vision and lateral to these vessels (transilluminating the wall helps in slim patients but is unreliable when subcutaneous fat is thick). See Pneumoperitoneum for the physiology in detail.
Energy and the late-injury problem
Electrosurgical injury prevention depends on understanding why thermal damage is insidious: lateral thermal spread, capacitive coupling, insulation failure and direct coupling can all deliver energy to bowel that is not in the field of view. The injured serosa may look intact, devitalise over days, then perforate. This is the rationale for keeping all active electrode tips in view, inspecting instrument insulation, using the lowest effective power, favouring bipolar or advanced vessel-sealing devices for pedicles, and being cautious with monopolar near bowel and ureter. The detail belongs to Electrosurgery safety, but the prevention principle stands: a thermal bowel injury you cannot see is the one that kills your patient a week later.
