  • 21. NSAIDs should be abandoned in GI anastomoses Anastomotic leak (AL) is the most important & one of the most serious complications after GI anastomosis Factors that contribute to increase the risk of AL should be identified and--if possible-eliminated Prostaglandins promote neo-angiogenesis & enhanced wound healing Non-steroidal anti-inflammatory drugs (NSAIDs) are often used for treating pain after surgical procedures
  • 22. NSAIDs be abandoned after primary GI anastomosis Retrospective, case-control study in 75 patients undergoing laparoscopic colorectal resection for colorectal cancer. 33 of these patients received the NSAID diclofenac in the postoperative period 42 did not receive any NSAID. There were significantly more LEAKS among the patients receiving diclofenac (7/33 vs. 1/42, p=0.018)
  • 23. NSAIDs should be abandoned after primary GI anastomosis Database study based on data from the Danish Colorectal Cancer Group's (DCCG) prospective database & electronically registered medical records. From the database information on demographic, surgical & postoperative variables (including AL) were provided. Information on NSAID consumption was retrieved by individual searches in the patients' medical records. Based on these data, uni- & multivariate logistic regression analyses were performed. These analyses identified NSAID treatment in the postoperative period as an individual risk factor for Leak

  • 28. Anastomotic Leak Prevention ALWAYS DO A SAFE ANASTOMOSIS Preop Factors Intra-op Factors Post Op Factors
  • 29. Leak Prevention ALWAYS DO A SAFE ANASTOMOSIS No Leak. Cause no persistent bleeding. Cause no stricture of the lumen. Create no risk for internal hernia.
  • 30. Patient Factors Affect GI Anastomitic Healing Look for these factors: Correct these factors or REJECT the Patient 1. Renal/Cardiac/Pulmonary Dysfunction 2. Bacterial contamination 3. Inflammation 4. Shock & hypoperfusion states 5. Diabetes mellitus 6. Chronic steroid use 7. Poor nutritional status 8. Malignancy
  • 31.

  • 32. Fundamentals of Gastro-Intestinal Anastomosis Healing Adequate local blood supply (Carefully maintain mesentery) Elimination of tension (Long Pouch,left gutter for bowel. Do Not Divide the Omentum) Meticulous Hemostasis (avoid damage to staple line) Gentle & precise handling of tissues Closure of mesenteric defects (Not in MGB) Close inspection Accurate Suture Placement (NOT Many Sutures, 3 layers are not better than 1-2)

  • 35. Fundamentals of Gastro-Intestinal Anastomosis Healing Inverted vs. Everted 1800s, Lembert, Halsted advocated an inverted, serosa-to-serosa anastomosis Hand-sutured everting bowel anastomosis point out Simplicity & decreased risk of bowel lumen narrowing Animal experiments in the 1960s & 1970s demonstrated no difference in healing strength & leak rates between the two approaches
  • 36. Fundamentals of Gastro-Intestinal Anastomosis Healing Approximately 3-mm gap between two sutures Care not to apply excessive tension to prevent cut-through of seromuscular layer It is necessary to include submucosa carefully because it is the strongest layer of the bowel wall and gives strength to anastomosis.
  • 37. Handle tissue gently & precisely “approximate, do not strangulate” to avoid ischemia of the bowel wall at the anastomosis. For stapled anastomoses, use the correct staple height for the tissue thickness. Too short & ischemia; Too long, & bleeding or leak The common staple height for the small bowel & colon is 3.5 blue, 3.5 mm For the thicker stomach, green, 4.8 mm
  • 38. Fundamentals of Gastro-Intestinal Anastomosis Healing 1 Layer, Maybe 2, Not More (Ischemia) Remember your general surgery Inverted => Narrowing of the Lumen & early complaints of Nausea & Vomiting Patient complaints, stress on the anastomosis & prolonged hospitalization Stapled vs Handsewn Buttress/Fibrin Glue/Omental Patch?
  • 39. Meta-analysis of randomized controlled trials single- vs two- layer intestinal anastomosis Six trials were analyzed, comprising 670 participants (single-layer group, n = 299; twolayer group, n = 371). Data on leaks were available from all included studies. Combined risk ratio 0.91 (95% CI = 0.49 to 1.69), & indicated no significant difference.

  • 43. Stapler Use Warnings Ensure to select a stapler with the appropriate staple size for the tissue thickness. Overly thick or thin tissue may result in unacceptable staple formation. Do not attempt to remove the shipping wedge until the stapler is loaded into the instrument. Do not squeeze the handle while pulling back the black retraction knobs. Do not attempt to override the safety interlock; to do so will render the stapler nonoperational. Failure to completely fire the stapler will result in an incomplete cut and incomplete staple formation, and may until in poor hemostasis.
