SU14.2-3 | Surgical Approaches, Instruments and Wound Closure — Summary & Reflection

KEY TAKEAWAYS

Surgical approach, instruments and closure are the mechanical core of every operation, and each choice follows principles you can reason out. Place an incision parallel to Langer's lines for the least tension and the finest scar, while giving adequate, extensible exposure and respecting the anatomical layers. Know the instrument families: cutting/dissecting (scalpel; Mayo for tough tissue, Metzenbaum for fine dissection), grasping (toothed forceps for skin/fascia, non-toothed and Babcock for delicate tissue, Allis for tissue to be excised), haemostatic artery forceps (Spencer Wells, mosquito, Kocher), and retractors (self-retaining versus hand-held). Classify sutures on two independent axes — absorbable versus non-absorbable (how long support lasts) and monofilament versus braided (tissue drag, knot security, infection risk) — so Vicryl is absorbable-braided and Prolene is non-absorbable-monofilament; choose the needle (round-bodied for soft tissue, cutting for tough tissue) and the technique (interrupted, continuous, subcuticular, mattress) for the wound, securing each with a square or surgeon's knot as an instrument tie that approximates but never strangles the edges. Joining hollow viscera obeys the anastomosis principles: good blood supply, no tension, accurate apposition and no distal obstruction. These skills are demonstrated and mastered in simulation before they reach a patient.

REFLECT

Think about a wound you have seen closed — a laceration sutured in casualty, a skin closure at the end of an operation, or a closure on a simulation pad. Could you now name the suture used and classify it on both axes, say why that needle was chosen, and judge whether each throw approximated or strangled the edges? When you next practise in the skills lab, watch your own hands: are you taking equal bites of each edge, following the curve of the needle, and tightening only to approximate? Reflect on one habit you will deliberately build now — perhaps holding delicate tissue only with non-toothed forceps, or stopping yourself before over-tightening a knot — so that gentle, principled technique becomes automatic before you operate on a real patient.
