What is Polya procedure?

Nearly 100 years ago, a man named George Polya designed a four-step method to solve all kinds of problems: Understand the problem, make a plan, execute the plan, and look back and reflect. Because the method is simple and generalizes well, it has become a classic method for solving problems.

How is a gastrojejunostomy performed?

Gastrojejunostomy can be done via either an open or a laparoscopic approach. Percutaneous gastrojejunostomy may be performed, in which a tube is placed through the abdominal wall into the stomach and then through the duodenum into the jejunum.

What is being removed during a Gastroenterostomy?

A gastroenterostomy is the surgical creation of a connection between the stomach and the jejunum. The operation can sometimes be performed at the same time as a partial gastrectomy (the removal of part of the stomach).

What is Polya reconstruction?

Polya’s operation It involves a resection of 2/3 of the stomach with blind closure of the duodenal stump and a retrocolic gastro-jejunal anastomosis.

What are the 4 steps in problem solving according to Polya?

Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving:

1. Step 1: Understand the problem.
2. Step 2: Devise a plan (translate).
3. Step 3: Carry out the plan (solve).
4. Step 4: Look back (check and interpret).

What is the Hofmeister technique for anastomosis?

The Hofmeister technique shown in Chapter 29is an alternative in which only a portion of the gastric length is used for the anastomosis (Chapter 29, figure 1). The jejunal loop is approximated to the posterior surface of the stomach adjacent to the staple line by a layer of closely placed, interrupted 00 silk mattress sutures (figure 3).

How is a gastrojejunostomy performed with Babcock forceps?

The jejunum is grasped with Babcock forceps and brought up through the opening made in the mesocolon, with the proximal portion in juxtaposition to the lesser curvature of the stomach (figure 2). With the Polya technique the gastrojejunostomy uses the entire length of the stomach and jejunum for the anastomosis.

What is the difference between polyA and Hofmeister technique?

With the Polya technique the gastrojejunostomy uses the entire length of the stomach and jejunum for the anastomosis. The Hofmeister technique shown in Chapter 29 is an alternative in which only a portion of the gastric length is used for the anastomosis ( Chapter 29, figure 1 ).

What is the position of the viscera after the operation is completed?

The schematic drawing (figure 1) shows the position of the viscera after this operation is completed, which in principle consists of uniting the jejunum to the open end of the stomach. The jejunum may be anastomosed either behind or in front of the colon.
