Bariatric (Weight Loss) Surgery: Postoperative vitamin and element replacement

January 1, 0001

Bariatric (Weight Loss) Surgery

Postoperative vitamin and element replacement

After a Gastric Bypass you are more likely to develop vitamin and elemental deficiencies. The duodenum and first part of the small bowel is on longer in contact with your ingested food. It is here that some vitamins and elements are absorbed into the blood stream. This is generally less following a Sleeve Gastrectomy, as there is no mal-absorptive component (the gut continuity is 'normal').

Bariatric (Weight Loss) Surgery: Roux-en-Y Gastric Bypass

Bariatric (Weight Loss) Surgery

Roux-en-Y Gastric Bypass

A Gastric Bypass is a major operation to create a small stomach pouch and rearrange the small bowel to partially "bypass or delay" the food eaten from being in mixed with the digestive enzymes. This results in both malabsorptive and restrictive changes that results in weight loss and generally improvement in various comorbidities (such as diabetes and hypertension).

Bariatric (Weight Loss) Surgery

The omega loop gastric bypass (mini-loop gastric bypass)

The Omega Loop is the reduction in the size of your stomach and re-arrangement of your small bowel such that the mixing of digestive enzymes / bile (required for the breakdown of calories / vitamins) with swallowed food is delayed (bypassed) to decrease absorption. This results in respective restrictive and malabsorptive changes that results in weight loss and generally improvement in various comorbidities (such as diabetes and hypertension).

Laparoscopic Hernia: Complications

Laparoscopic Hernia

Complications

Bleeding and infection rates are very low. Occasionally there can be bruising in the inguinal region.

Recurrence rates for the Laparoscopic inguinal hernia is approximately 1%, this is similar to the traditional Open inguinal hernia repair.

Conversion to an Open Inguinal hernia (i.e. larger scar) repair occurs in less than 1%.

Laparoscopic Hernia: Keyhole repair of inguinal hernia

Laparoscopic Hernia

Keyhole repair of inguinal hernia

The Laparoscopic inguinal hernia (Totally Extra Peritoneal; TEP) surgery is a technique to repair your hernia with three small scars placing the mesh in the preperitoneal plane.

This has a number of advantages

  • Improved recovery
  • Less chronic pain
  • The mesh is in a more physiologically appropriate layer of the abdominal wall
  • Indicated in repair of recurrent hernia
  • Indicated in bilateral hernia (both left and right)

Preoperative cares

You may be told to discontinue your blood thinning agents preoperatively.

Mesh is indicated in inguinal hernia repairs and has been used successfully for over 30 years. The NZ General Surgical Association recently released a statement affirming the above.
