Mini-Gastric Bypass Outperforms Both Lap and Open Roux-en-Y

	Mini-Gastric Bypass	Lap-RNY	Open RNY
Time Spent in OR (min)	38 + 35	246 + 70	294 + 79
Estimated Blood Loss (ml)	50 + 150	135 + 91	513 + 274
ICU Stay (days)	less than 0.5 %	0.6 + 2.7	2.3 + 2.6
Hospital Stay (days)	1.1 + 3.4	4.0 + 3.7	8.4 + 3.2

Hospital Stay

Hospital stay was also compared in the study. The average stay was 4 days for Lap RNY patients and over 8 days on average for Open RNY patients. In our series of Mini-Gastric Bypass patients the average length of stay is now 1 day.

Operating Times

In the study by Nguyen operating times after both Lap and Open Roux-en-Y Gastric Bypass were 246 minutes (4.1 hours) in Lap RNY patients and 294 minutes (4.9 hours) in open RNY patients. Our average times in uncomplicated Mini-Gastric Bypass patients ranges from 38 minutes.

Blood Loss

In the same study the blood loss after both Lap and Open Roux-en-Y Gastric Bypass were reported as 135 ml. in Lap RNY patients and 513 ml. in the open RNY patients. Our average blood loss in Mini-Gastric Bypass patients averages 50 ml. Results of the Mini-Gastric Bypass appear to be better than in the Roux-en-Y, Open or Laparoscopic.

Intensive Care Unit Stay

The average stay in the Intensive Care Unit (ICU) after Lap and Open Roux-en-Y Gastric Bypass were an average of 0.6 days in Lap RNY patients and 2.3 days in open RNY patients. Only 5 patients of the last 1,320 patients have had to go to the ICU for an average ICU stay of less than .1 days.

- The most commonly preformed gastrointestinal weight loss surgery performed in the US is the Roux-en Y Gastric Bypass (RYGB).

In both open and laparoscopic Roux-en-Y bypass, the stomach is divided creating a small pouch, which is closed, by several rows of staples. The remaining portion of the stomach is not removed but is �bypassed�, and plays a diminished role in the digestive process. A Y shaped portion of the small intestine is then attached to the pouch. The volume the pouch is capable of holding is approximately 1 oz. Weight loss occurs as a result of reduction of calories, alteration in gut appetite hormones and decreased nutrient absorption.

The risks associated with the Roux-en-Y Gastric Bypass, include:

	RNY	MGB
Stomal obstruction	(5-15% )	0.08%
Postoperative bleeding	1-5%	0.5%
Small bowel obstruction	1-10%	0.07%
Gastrointestinal leak	1-5%	1%
Deep vein thrombosis	1-2%	0.14%
Splenectomy	1%	0%
Pulmonary embolus	0.5-2.6%	0.14%
Death within 30 days	0.5-2%	0.07%
Anemia	10%	4%
Incisional hernia	1-10.2%	0.21%
Protein-calorie malnutrition	~1%	1%
