    Study Notes

    Surgical Anatomy and Techniques

    • Ligament of Treitz: connects the duodenum to the jejunum; significant landmark in gastrointestinal anatomy.
    • Blood supply to the stomach and intestines comes from:
      • Celiac trunk: branches include splenic, common hepatic, and left gastric arteries.
      • Superior mesenteric artery: supplies small intestine, ascending colon, and ⅔ of the transverse colon.
      • Inferior mesenteric artery: supplies transverse colon down to rectum.

    Bowel Isolation Techniques

    • Initiated upon clamping and opening of the gastrointestinal tract to prevent cross-contamination and metastasis of malignant cells.
    • Bowel instruments kept separate from clean instruments in a K-basin.
    • Extra draping may be added around the incisional area for enhanced isolation.
    • Surgical team must change gloves and gowns post-anastomosis and before closure.

    Stapling Devices in Surgery

    • GIA (Gastrointestinal Anastomosis): facilitates side-to-side anastomosis, able to handle different lumen sizes, available in endoscopic form.
    • TA (Thoracoabdominal Stapler): staples tissue together; requires manual cutting.
    • EEA (End to End Anastomosis) or ILS (Intraluminal Stapler): performs circular cuts for end-to-end or end-to-side anastomosis, primarily used in the lower bowel.

    Mesenteric Repair

    • Dissection of mesenteries during bowel removal necessitates repair to prevent post-operative bowel entrapment and obstruction.

    Bariatric Surgery

    • Roux-En-Y Gastric Bypass: reduces stomach size, connects to the jejunum, leading to reduced calorie absorption and increased satiety.
    • Gastric Lap Band: adjustable band around the stomach restricts food intake.
    • Sleeve Gastrectomy: removes 85% or more of the stomach to limit food intake.

    Colostomy/Ileostomy

    • Temporary procedures allow bowel rest due to disease or facilitate anastomosis healing.
    • Hartmann's Procedure entails a colostomy with a closure of the distal stump, allowing return surgeries after a healing period.
    • Permanent colostomies may occur after cancer surgery.

    Uterine Procedures

    • CRUB ligaments (Cardinal, Uterosacral, Round, Broad) play a crucial role in uterine stabilization.
    • D & C (Dilation and Curettage): uterine lining scraping performed for heavy bleeding or post-miscarriage.
    • Vault Count: surgical count method when entering or removing the cervix.

    Hysterectomy Types

    • Total Abdominal Hysterectomy: removes uterus and cervix.
    • Partial/Subtotal: removes only the uterus.
    • Radical Hysterectomy: encompasses removal of uterus, cervix, fallopian tubes, ovaries, and surrounding lymph nodes.

    Kidney Transplant

    • Typically performed laparoscopically for enhanced recovery; donor kidneys from younger, healthy individuals with intact blood flow are preferred.
    • Anastomosis involves connecting the donor's renal artery and vein to recipient's iliac artery and vein.

    Prostate Surgery

    • Various techniques such as Suprapubic and Simple Retropubic Prostatectomy focus on removing the prostate to alleviate urinary obstruction.
    • Nerve Sparing Radical Retropubic Prostatectomy protects erectile function while excising cancerous prostate tissue.

    Lung Surgery

    • VATS (Video-Assisted Thoracoscopic Surgery) allows for lobectomy and wedge resection of lung lesions with minimized recovery time.
    • Double lumen ETT facilitates single-lung ventilation during procedures.
    • Esophagectomy techniques vary, including transhiatal and transthoracic methods for esophageal cancer treatment.

    Interventions for Cardiac Procedures

    • Cardiac catheterization reveals coronary arteries' health for planning bypass grafts, using synthetic sutures for vascular repair.
    • Cardiopulmonary Bypass Machine (CPBM) diverts blood flow during heart surgery, allowing surgeons to operate on a still heart.

    Medications and Solutions in Surgery

    • Heparinized solutions prevent clotting during procedures; Papavarine serves as a vasodilator.
    • CABG focuses on revascularization in patients with severe coronary artery disease using mammary artery grafts for effective long-term results.

    Additional Surgical Terms

    • Ureteroscopy and urethroscopy are procedures for stone removal from the urinary tract.
    • Pyelithotomy involves the extraction of stones from the renal pelvis.
    • Orchidopexy fixes undescended testicles back into the scrotum.

    Surgical Anatomy and Techniques

    • Ligament of Treitz: connects the duodenum to the jejunum; significant landmark in gastrointestinal anatomy.
    • Blood supply to the stomach and intestines comes from:
      • Celiac trunk: branches include splenic, common hepatic, and left gastric arteries.
