Surgical outcome of stapled and handsewn anastomosis in lower gastrointestinal malignancies: A prospective study

This is the authors' abstract. We don't add key points for this paper.

Background: In spite of the wide range of intestinal anastomotic techniques, surgeons are still not so confident with colorectal anastomosis. Invention of surgical staplers has provided some procedural advantages and sense of security to surgeons as well as to patients, in respect to sphincter-saving procedures and thereby improving the quality of life. Outcome measures of applying these devices should be evaluated to see its efficacy and cost-effectiveness over conventional handsewn technique in treatment plan. The result of such comparative study may help surgeons to improve results of their technique. The aim of this prospective study is to observe the results of using stapler in comparison to handsewn colorectal anastomosis. Patients and Methods: A total of 60 patients were selected, of which 30 underwent “stapled” and 30 underwent “handsewn” anastomosis. The two groups were compared on the following points (i) mean operating time (min), (ii) resumption of oral feeding, (iii) wound infection rate, (iv) anastomotic leak rate, (v) duration of hospital stay and return to work in days. The procedures were evaluated and presented.Results: The stapling procedure took shorter operative time compared to the handsewn anastomosis with a mean of 123 ± 21.1 min and 161.5 ± 27.8 min respectively (P < 0.001). Oral feeding was started earlier in patients who underwent stapler anastomosis 4.0 ± 1.0 days, as compared to handsewn anastomosis 5.0 ± 0.83 days (P value = 0.001). There was no significant difference between the two groups in postoperative hospital stay; it was 7.8 ± 1.76 days and in controls group it was 8.1 ± 2.12 (P > 0.0137).Conclusion: Application of the stapler in treating lower gastrointestinal malignancies demonstrated better effects in terms of mean operating time, resumption of oral feeds, and hospital stay.
