Sleeve Gastrectomy Calibration Tube And Method Of Using Same
One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. The one or more medical devices may include a laparoscopic sleeve gastrectomy stapling guide in conjunction with a calibration tube in accordance with one or more examples. According to an example, the calibration tube may be a flared, multi-diameter calibration tube. The flared, multi-diameter calibration tube may have a first diameter along a portion of the tube and a second diameter that may larger than the first diameter along at least another portion of the tube. The calibration tube may be used in conjunction with the stapling guide to align stomach such that it may be stapled along the stapling guide (e.g., to perform the vertical sleeve gastrectomy).
1 . A method for performing a sleeve gastrectomy, the method comprising the steps of:
providing a first medical device including:
(i) a tube for insertion into an interior of a stomach, the tube having a proximal end and a distal end; and
(ii) a balloon portion, the balloon portion having a first deflated configuration for insertion into the interior of the stomach and a second inflated configuration, wherein the balloon portion is positioned at about the distal end of the tube;
providing a second medical device, the second medical device being a single-use linear stapler, wherein the single-use linear stapler has a single cartridge such that a complete gastrectomy staple line is formed with the single cartridge along a resection line, the resection line being defined at least partially by the balloon portion in the second inflated configuration in cooperation with the single-use linear stapler;
inserting the first medical device into an interior of a stomach;
positioning the second medical device on an exterior of the stomach relative to and anatomically lateral to the first medical device; and
cutting the stomach using the second medical device to resect a portion of the stomach to form a sleeve.
2 . The method of claim 1 , further comprising operating the second medical device to provide a staple line.
3 . The method of claim 1 , wherein the second medical device has a first end and a second end and having a length therebetween, the length extending from about a pylorus of the stomach to about a gastroesophageal junction (GEJ) of the stomach.
4 . The method of claim 3 , wherein the second medical device is positioned relative to and anatomically lateral to the balloon portion of the first medical device such that the first end of the second medical device is positioned about one centimeter to about three centimeters laterally from the balloon portion of the first medical device.
5 . The method of claim 3 , wherein the second medical device is positioned about zero to about two centimeters relative to and anatomically lateral to the calibration tube at the GEJ.
6 . The method of claim 3 , wherein the second end of the second medical device is positioned anatomically lateral to the calibration tube at the GEJ.
7 . The method of claim 6 , wherein the second end of the second medical device is positioned about zero to about two centimeters relative to the calibration tube at the GEJ.
8 . The method of claim 3 , wherein the second medical device is positioned relative to and anatomically lateral to the first medical device such that a substantially linear resection line for the sleeve gastrectomy is defined by the balloon portion of the first medical device and the second medical device;
9 . The method of claim 1 , wherein the balloon portion includes a non-compliant balloon.
10 . The method of claim 1 , wherein the tube has a first diameter and the balloon portion has a second diameter larger than the first diameter.
11 . The method of claim 1 , wherein, after being inserted, the balloon portion is positioned at about an incisura angularis along a lesser curvature of the stomach.
12 . The method of claim 1 , wherein the balloon portion has a first deflated position for insertion into the stomach and a second inflated position for laterally displacing the lesser curvature of the stomach.
13 . The method of claim 12 , wherein the balloon portion has a first diameter in the first deflated position and a second diameter in the second inflated position, wherein the second diameter is from about 0.5 cm to about 2 cm.
14 . The method of claim 13 , wherein the first diameter of the balloon portion in the first deflated position is substantially the same as the first diameter of the tube.
15 . The method of claim 1 , wherein an interaction between the first medical device and the second medical device positions the second medical device in a desired position.
16 . The method of claim 1 , wherein positioning the second medical device further comprises:
moving the first medical device from a first position to a second position,
wherein the movement of the first medical device from the first position to a second position causes a corresponding movement of the second medical device from a first position to a second position.
17 . A method for performing a sleeve gastrectomy, the method comprising the steps of:
providing a first medical device including:
(i) a tube portion for insertion into an interior of a stomach; and
(ii) a balloon portion, the balloon portion having a first deflated configuration for insertion into the interior of the stomach and a second inflated configuration;
providing a second medical device, the second medical device being a linear stapler, wherein the linear stapler has a single cartridge such that a complete gastrectomy staple line is formed with the single cartridge along a resection line, the resection line being defined at least partially by the balloon portion in the second inflated configuration in cooperation with the linear stapler;
inserting the first medical device into an interior of a stomach;
positioning the second medical device on an exterior of the stomach relative to and anatomically lateral to the first medical device; and
cutting the stomach using the second medical device to resect a portion of the stomach to form a sleeve.
18 . The method of claim 1 , further comprising operating the second medical device to provide a staple line.
19 . The method of claim 1 , wherein an interaction between the first medical device and the second medical device positions the second medical device in a desired position.
20 . The method of claim 1 , wherein positioning the second medical device further comprises:
moving the first medical device from a first position to a second position,
wherein the movement of the first medical device from the first position to a second position causes a corresponding movement of the second medical device from a first position to a second position.
