Operative laparoscopy — entry, energy, port placement and complications
Also known as Laparoscopic surgery · Minimally invasive gynaecological surgery · Veress needle entry · Hasson open entry · Direct trocar insertion · Palmer's point entry · Laparoscopic entry injury · Port-site hernia · Laparoscopic electrosurgery
Exam-exhaustive FRANZCOG fellowship reference on operative laparoscopy — the three entry techniques (closed Veress, open Hasson, direct optical/direct trocar), energy sources (monopolar, bipolar, advanced bipolar, ultrasonic), port placement and fascial closure, and the complications that drive mortality and litigation (major vessel injury, unrecognised bowel/thermal injury, gas embolism, port-site hernia). Grounded in the Cochrane review of laparoscopic entry techniques, the SOGC No. 193 entry guideline, and the AAGL/RCOG energy and entry literature. RANZCOG-primary, globally tagged to MRCOG, ABOG and FRCSC.

Red flags
- Sudden brisk dark blood or rapid haemodynamic collapse during or immediately after entry — major vessel injury, desufflate and apply direct pressure now
- Cardiovascular collapse with fall in end-tidal CO2 during insufflation — gas embolism, stop the gas and go to Durant's position
- Fever, pain out of proportion or peritonitis from day 2 onward after laparoscopy — the unrecognised bowel enterotomy or thermal burn, the killer delayed diagnosis
- No entry technique is proven safest — choose by patient risk: open or Palmer's point for the scarred abdomen, never default the umbilicus
- Closing a port defect under 10 mm but leaving a 10 mm or larger defect open — port-site hernia is around 0.7 percent and preventable
- Monopolar energy near bowel, or an uninspected instrument with insulation failure — capacitive coupling and thermal injury wait out of view
You are the registrar on a quiet Tuesday list. The first case is a diagnostic laparoscopy for pelvic pain in a thin 24-year-old. The Veress is in, the gas is running, and within ten seconds the anaesthetist says her pressure has dropped and the end-tidal CO2 has fallen. Laparoscopy is the most common operation you do, and the moments that end careers happen in the first ninety seconds of it. This topic is your rehearsal for those ninety seconds, and for the days that follow.[8][11]
Overview and definition
Laparoscopy is a closed endoscopic operation of the abdomen and pelvis, and in gynaecology it spans everything from a diagnostic look to total laparoscopic hysterectomy, single-port (LESS) surgery and robot-assisted procedures. What unites them is the same first problem: you must get into the peritoneum safely, and you must do it largely blind.[2][6]
Three primary entry strategies define the field, and you should name them in that order:[1][2]
- Closed entry — Veress needle to create the pneumoperitoneum, then a trocar to enter.
- Open (Hasson) entry — a mini-laparotomy cut-down to the peritoneum under direct vision, then a blunt port.
- Direct entry — direct trocar insertion, with or without optical guidance, before insufflation.
Around these sit the technologies that modify each: disposable shielded trocars, radially expanding (STEP) trocars, and visual entry systems such as the trocarless threaded visual cannula.[2][5]
