Embodiment

[0191] The present invention will be further described with reference to the following examples, which are only to illustrate the present invention, but not to limit the scope of the present invention.

[0192] Ultra-low anterior rectal resection at the anterior perineal plane (APPEAR technique)

[0193] Fourteen patients were enrolled, of which, 7 were tumors, 5 were ulcerative colitis, and 2 were traumatic rectal injuries. Patients were evaluated before and after a median of 2 years.

[0194] Nine of the 14 patients underwent a reversal of the ileostomy and underwent at least one year of follow-up, and one patient was waiting for closure. Due to stoma-perineal fistula, four patients have not yet considered reversal of ileostomy. Three of the 14 patients had records of transient dysfunction, but no urinary system disease occurred.

[0195] When performing APPEAR surgery for tumor or trauma patients, the postoperative median incontinence (Wexner) score is 5 (range 0-8, n=6), and th...

Abstract

The present invention relates to a stapler apparatus, comprising a stapler having a proximal end, a distal end and a longitudinal axis, the stapler further comprising a trigger, an anvil docking pin aligned substantially parallel with the longitudinal axis of the stapler, and a stapling means, the anvil docking pin and stapling means being at the distal end of the stapler, and a detachable anvil, comprising an anvil head and an anvil shaft, wherein the anvil shaft is adapted to receive the anvil docking pin and operation of the trigger causes the stapling means to be actuated, characterised in that the length of the anvil shaft is at least 4 cm. The present invention also relates to a method of forming an anastomosis between two surfaces using the stapler apparatus of the invention and a method of forming a stoma trephine in a subject using the stapler apparatus of the invention.; The present invention further relates to the use of the stapler apparatus or anvil for a stapler apparatus in such methods and a kit of parts comprising the stapler apparatus of the invention and additional components.

Description

Technical field [0001] The invention relates to a method and a device for generating trephine and anastomosis in a cavity in traditional open surgery and laparoscopic surgery. Background technique [0002] A large number of diseases require segmental resection to remove part of an organ. For example, inflammatory bowel disease (such as Crohn's disease, ulcerative colitis), colorectal cancer, and bowel infarction may require removal of part of the lower digestive (gastrointestinal) tract. After resection, the two ends of the gastrointestinal tract must be connected to each other to maintain the functioning of the organs. This rejoining process is called surgical anastomosis. [0003] A stoma is an artificial opening between two hollow organs or between a hollow organ and the body. The production of artificial stoma, such as colostomy, ileostomy, urethostomy, esophagostomy and gastrostomy, can be a very useful medical intervention in the treatment of diseases, especially for norma...
