Abstract

Methods and devices are provided for performing gastroplasties. In one embodiment, a method of performing a gastroplasty includes gaining access to a stomach of a patient through an opening formed in the patient'"'"'s abdominal wall. A multiple port access device having two or more sealing ports through which surgical instruments can be inserted can be positioned in the abdominal opening. Various instruments can be inserted through the various sealing ports to perform certain steps, such as tensioning and cutting tissue, sizing and transecting the stomach, viewing the surgical site, etc. The methods and devices can be used to perform a Magenstrasse and Mill procedure in which only a portion of the stomach is transected.

Claims

1. A surgical method, comprising:

positioning a housing having a plurality of sealing ports in an abdominal wall of a patient; and

transecting a greater curvature of a stomach of the patient from a lesser curvature of the stomach using a surgical instrument inserted through one of the plurality of sealing ports in the housing to form a gastric tube along the lesser curvature that drains into an antrum of the stomach.

2. The method of claim 1, further comprising visualizing an abdominal cavity of the patient with a scoping device inserted through one of the plurality of sealing ports in the housing.

3. The method of claim 1, further comprising, prior to transecting, forming an opening through anterior and posterior walls of the stomach.

4. The method of claim 3, further comprising determining a location for the opening by using a scoping device inserted through one of the plurality of sealing ports in the housing to visualize the stomach between the antrum and an angle of His.

5. The method of claim 4, further comprising measuring a distance between a pylorus of the patient and the greater curvature of the stomach.

6. The method of claim 1, further comprising transorally introducing a sizing device into the stomach and using the sizing device to size the portion of the stomach to be transected.

7. The method of claim 1, further comprising retracting a liver of the patient using a device inserted through one of the plurality of sealing ports in the housing.

8. The method of claim 1, further comprising tensioning a tissue attached to the stomach using a grasper inserted through one of the plurality of sealing ports in the housing, and detaching at least a portion of the tissue from the stomach using a second surgical instrument inserted through one of the plurality of sealing ports in the housing.

9. The method of claim 8, wherein the second surgical instrument includes an optically clear distal end to allow visualization of the stomach during detaching of at least a portion of the tissue.

10. The method of claim 1, further comprising bending at least one flexible joint along a longitudinal length of the surgical instrument to position the surgical instrument for transecting.

11. The method of claim 1, further comprising forming an access hole in the abdominal wall by inserting a trocar through the abdominal wall, and tensioning a tissue attached to the stomach using a grasper inserted through the trocar.

12. The method of claim 1, wherein the surgical instrument comprises a surgical stapler.

13. The method of claim 1, wherein the housing is positioned to form an access hole through an umbilicus of the patient.

14. The method of claim 13, wherein the access hole has a diameter in a range of about 15 to 35 millimeters.

15. A surgical method, comprising:

forming a first access hole in an abdominal wall of a patient by positioning a housing having a plurality of sealing ports therein in the abdominal wall;

forming a second access hole in the abdominal wall by inserting a trocar through the abdominal wall; and

transecting a portion of a stomach of the patient between an opening formed through posterior and anterior walls of the stomach and an angle of His of the stomach using a surgical instrument inserted through one of the housing and the trocar.

16. The method of claim 15, further comprising visualizing an abdominal cavity of the patient with a scoping device inserted through one of the housing and the trocar.

17. The method of claim 15, wherein the first access hole has a diameter greater than a diameter of the second access hole.

18. The method of claim 15, further comprising determining a location for the opening by using a scoping device inserted through one of the housing and the trocar to visualize the stomach between an antrum of the stomach and the angle of His.

19. The method of claim 15, further comprising transorally introducing a sizing device into the stomach and using the sizing device to size the portion of the stomach to be transected.

20. The method of claim 15, further comprising tensioning a tissue attached to the stomach using a grasper inserted through one of the housing and the trocar, and detaching at least a portion of the tissue from the stomach using a dissecting surgical instrument inserted through one of the housing and the trocar.

21. The method of claim 20, wherein the grasper is inserted through one of the plurality of sealing ports in the housing and the dissecting surgical instrument is inserted through another one of the plurality of sealing ports in the housing.

22. The method of claim 20, wherein tensioning a tissue attached to the stomach comprises using at least one additional grasper inserted through the one of the housing and the trocar through which the other grasper is not inserted.

23. The method of claim 20, wherein the dissecting surgical instrument includes an optically clear distal end to allow visualization of the stomach during detaching of at least a portion of the tissue.

24. The method of claim 15, further comprising bending at least one flexible joint along a longitudinal length of the surgical instrument to position the surgical instrument for transecting.

25. A surgical method, comprising:

positioning a housing having a plurality of sealing ports in an abdominal wall of a patient to form an access hole through the abdominal wall;

transorally inserting a sizing device into a stomach of the patient;

using the sizing device to size a portion of the stomach to be transected; and

transecting the portion of the stomach using a surgical stapler inserted through the abdominal wall through one of the plurality of sealing ports in the housing.

26. The method of claim 25, further comprising forming a second access hole in the abdominal wall by inserting a trocar through the abdominal wall, inserting a grasper through the abdominal wall through the trocar, and tensioning a tissue attached to the stomach using the grasper.

27. The method of claim 26, further comprising detaching at least a portion of the tissue from the stomach using a dissecting surgical instrument inserted through one of the plurality of sealing ports in the housing.

28. The method of claim 25, further comprising inserting a scoping device through the abdominal wall through one of the plurality of sealing ports in the housing, and using the scoping device to locate a starting location for the surgical stapler to start transecting the portion of the stomach.
