  2. How to join them back?

  3. Bowel Anastomosis Handsewn Stapled Compression ring device

  4. Handsewn anastomosis • First successful manual anastomosis in late 19th century • Single layer vs double layer • Continuous vs interrupted

  5. Stapled anastomosis • First introduced in 1908 • Stapling device deploys and bend staples to secure tissue in place • Range of choice of device for open and laparoscopic use, for different tissue thickness, circular or linear, cutting or non cutting

  6. Compression ring device • Sutureless anastomosis based on two opposing rings that trap the ends of transected bowel • Subsequent ischemia and eventual sloughing of the trapped bowel, releasing the rings into the fecal stream • Possible problem of foreign body retention

  7. Which technique to choose?

  8. Stapled versus handsewn methods for colorectal anastomosis surgeryNeutzling CB. Cochrane Database Syst Rev. 2012. • Systemic review comparing 9 RCTs • Compared mortality, dishiscence, stricture, haemorrhage, reoperation, wound infection, procedure duration, hospital stay • No statistical significant differences except • Stricture was more frequent with stapling (P < 0.05) • Time taken was longer with handsewn techniques • Conclusion: No superiority of stapled over handsewn technique in colorectal anastomosis, regardless of the anastomotic level

  9. Bowel anastomoses: The theory, the practice and the evidence base Goulder F. World J Gastrointest Surg 2012 September 27; 4(9): 208-213 • Review on articles relating to small bowel, colonic and colorectal anastomotic technique from 1960 to 2010 • Suggested either a stapled or sutured anastomosis is acceptable in most situations. • Sutured or endoluminal circular stapled techniques are equally suitable for colorectal anastomoses (level 1a evidence), although the incidence of strictures is higher following stapled anastomoses.

  10. Bowel anastomoses: The theory, the practice and the evidence base Goulder F. World J Gastrointest Surg 2012 September 27; 4(9): 208-213 • A stapled side-to-side ileocolic anastomosis is preferable following a right hemicolectomy for cancer. (level 1a evidence) • A stapled side-to-side anastomosis is likely preferable after an ileocolic resection for Crohn’s disease. (level 1b evidence) • small bowel anastomoses should be sutured in the trauma patient (Level 3 evidence)

  11. Systematic Review of the Technique of Colorectal Anastomosis Slieker J.C, Daams F., Mulder I.M., et al. JAMA Surg. 2013;148(2):190-201. • Review on 117 clinical and experimental articles in the past 4 decades • Review of studies on: • suture material, • suture format (size of suture bites, in-between distance of bites, suture tension, configuration of the bite, and inverting vs everting sutures), • single- vs double-layer colorectal anastomosis, • interrupted vs continuous sutures, • configuration of colorectal anastomosis (end-to-end, end-to-side, side-to-end, side-to-side, length of the side-limb, and length of the enterotomy), • hand-sewn vs stapled colorectal anastomosis, • hand-sewn vs compression colorectal anastomosis

  12. Systematic Review of the Technique of Colorectal Anastomosis Slieker J.C, Daams F., Mulder I.M., et al. JAMA Surg. 2013;148(2):190-201. • Single-layer continuous suture technique by an inverting technique with slowly absorbable monofilament material seems preferable (level 1b evidence) • Little evidence available for all aspects of hand-sewn colorectal anastomosis • Dedicated, high-volume colorectal surgeon has a role in lowering the incidence of anastomotic leak

  13. Systematic Review of the Technique of Colorectal Anastomosis Slieker J.C, Daams F., Mulder I.M., et al. JAMA Surg. 2013;148(2):190-201. • Stapling and hand-sewn anastomoses give equal leakage rate (level 1a evidence) • Compression and hand-sewn colorectal anastomosis have similar leakage rates (level 1b evidence)

  14. Compression anastomosis ring device in colorectal anastomosis: a review of 1,180 patientsMasoomi H, Luo R, Mills S, Carmichael J.C. Senagore A.J, et al. The American Journal of Surgery (2013) 205, 447-451. • Retrospective study on outcome of 1180 patients underwent elective laparoscopic or open left sided colectomy using compression device (ColonRing) between 2008-2010 • Data from NiTi Surgical Solutions database

  15. Compression anastomosis ring device in colorectal anastomosis: a review of 1,180 patientsMasoomi H, Luo R, Mills S, Carmichael J.C. Senagore A.J, et al. The American Journal of Surgery (2013) 205, 447-451. • The overall anastomotic leak rate was 3.22% (38 patients), within the expected rate of 3-5%. • Leak rate is lower in left sided colectomy (3.79% ) than in anterior resection (1.93%) • The median ring expulsion time was 8 days. The ring did not expel in one patient. • Concluded that ColonRing is a feasible and safe alternative for end-to-end colorectal anastomosis.

  16. In summary… • No superiority of stapled over handsewn technique in colorectal anastomosis, regardless of the anastomotic level • Either stapled or sutured techniques are suitable in most situations • Specific situations: • Right hemicolectomy for cancer: stapled side-to-side ileocolic anastomosis • Ileocolic resection for Crohn’s disease : stapled side-to-side anastomosis is likely preferable • Handsewn preferred in small bowel resection following trauma

  17. In summary… • Evidence on detail aspects of handsewn anastomotic technique is lacking. • Single-layer continuous suture technique, by an inverting manner, with slowly absorbable monofilament material seems preferable for colorectal anastomosis. • Compression and hand-sewn colorectal anastomosis have similar leakage rates • More study on compression device warranted

  18. What should we choose? Equipment availability Patient and disease factor Surgeon’s experience and preference Meticulous technique Good blood supply No tension
