Laparoscopy vs laparotomy
Formal Definition
Two distinct surgical approaches to the abdominal cavity: laparoscopy utilizes small incisions (typically 3-4 ports of 5-12mm) through which a camera (laparoscope) and instruments are inserted after insufflation with CO2 to create a working space (pneumoperitoneum, typically 12-15 mmHg); laparotomy is the traditional open approach with a single large incision (midline, transverse, or specific named approach) providing direct wide exposure of intra-abdominal contents; laparoscopy when feasible offers reduced postoperative pain, shorter length of stay, faster return to function, lower wound complication rates, while laparotomy may be necessary for extensive disease, severe inflammation, hemodynamic instability, or when visualization/maneuverability is inadequate.
How It's Used on the Ward
"Lap vs open" or "minimally invasive vs open" — the choice of approach when scheduling an abdominal case; increasingly, robotic-assisted laparoscopy is replacing traditional laparoscopy (the surgeon operates from a console using robotic arms for increased precision and 3D visualization); some operations are still best done open (e.g., extensive oncologic resections with complex reconstruction).
Example
""62-year-old with right colon adenocarcinoma, no prior abdominal surgery, BMI 28, well-nourished, no significant comorbidities. Robotic-assisted laparoscopic right hemicolectomy planned — 4 robotic ports (12mm camera, two 8mm robotic arms, 12mm assistant port), pneumoperitoneum to 12 mmHg, medial-to-lateral dissection with intracorporeal anastomosis. Estimated OR time 3h. Anticipated LOS 2-3 days, return to baseline activity by 2 weeks.""
Clinical Context
When laparoscopy is preferred: cholecystectomy (gold standard), appendectomy, inguinal hernia repair, bariatric (sleeve, bypass), adrenalectomy, nephrectomy, colectomy (increasingly standard), hysterectomy, prostatectomy (robotic). When laparotomy is still preferred: severe peritonitis with hemodynamic instability (damage control laparotomy), extensive cancer requiring complex multivisceral resection, large aneurysm repair, surgeon's preference based on training, prior multiple abdominal surgeries with dense adhesions (relative contraindication to laparoscopy — though experienced laparoscopists can often do safely), inability to tolerate pneumoperitoneum (severe COPD, cardiac disease where CO2 insufflation worsens hemodynamics). Contraindications to laparoscopy: uncorrected coagulopathy, severe cardiac/pulmonary disease unable to tolerate pneumoperitoneum, increased ICP. Pneumoperitoneum complications: CO2 embolism (rare), gas embolism, positioning injuries, venous compression reducing preload. Conversion to open rate: 5-15% depending on case. Benefits of laparoscopy vs open when equivalent oncologic outcomes: less pain, faster recovery, fewer wound complications (SSI, hernia), shorter LOS, better cosmesis.
