Subtotal Gastrectomy, Antrectomy, Billroth II and Roux-en-Y Reconstruction and Local Excision in Complicated Gastric Ulcers

153

 

 

 

STEP 3

Braun’s anastomosis

 

 

 

 

Braun’s anatomosis is performed as distal as possible (>40cm) to avoid biliary reflux into the gastric remnant. Side-to-side jejunostomy is done either with single stitches, a running suture, or a stapler device (A, B, C).

Roux-en-Y Reconstruction

 

 

Procedure

 

 

 

 

STEP 1

Dissection of the jejunum

 

 

The ligament of Treitz is identified, and the jejunum is dissected about 40–50cm distal to

 

 

Treitz’ ligament (A). For convenience, a stapler device may be used. The blind end of the

 

distal part is closed using a running suture or single stitches. The distal loop is placed

 

side-to-side to the posterior wall of the gastric remnant without exerting any tension

 

on the mesentery. A retrocolic route is preferable. Before performing the anastomosis,

 

the serosa of the jejunal loop is fixed to the serosa of the gastric remnant over a distance

 

of 5–6cm, thus building the outer layer of the backward suture (B).

STEP 2

Gastrojejunostomy

 

 

 

 

The jejunal loop and the gastric wall are opened along the antimesenteric border using electrocautery, and the posterior part of the anastomosis is done with a running suture representing the inner layer, completed by a running inverting suture on the anterior part of the gastrojejunostomy.

However, single stitches in monolayer technique as well as the appliance of a stapler device are also adequate. The technique is similar to the gastrojejunostomy in the Billroth II reconstruction (STEP 2).

The dissected jejunal loop is anastomosed end-to-side to the distal part of the jejunum 40–50cm distal to the ligament of Treitz.

Postoperative Investigations

The gastric tube should be kept until there are no further signs of gastric reflux or gastrointestinal atonia are present. Indwelling drains should be kept until enteral nutrition has been started.

Postoperative Complications

Short term:

Insufficiency of the gastrojejunostomy

Insufficiency of the duodenal stump

Acute pancreatitis, pancreatic fistula

Early dumping syndrome

Biliary stricture

Long term:

Biliary reflux

Stricture of the gastrojejunostomy

Stump carcinoma

Late dumping syndrome

SECTION 2

Esophagus, Stomach and Duodenum

 

 

 

 

Local Excision in the Stomach

 

 

Introduction

 

 

Ulcers that do not respond to medical treatment, perforation, or bleeding require

 

surgical intervention. In bleeding, an endoscopic treatment is the firstline approach.

 

If bleeding cannot be controlled by endoscopic means, surgical excision is the therapy

 

of choice.

 

 

Local excision in the stomach is indicated when the extension of the ulcer allows for

 

readaption without exerting any tension on the anastomosis.

 

The test for Helicobacter pylori and the maintenance of antacid medication are

 

mandatory. Work-up includes gastrin testing and testing for elevated serum calcium

 

levels, both risk factors in complicated ulcers.

 

 

Indications and Contraindications

 

 

Endoscopically uncontrollable bleeding and perforation are indications.

Indications

 

for an emergency procedure.

 

Standard Preoperative Investigations

In Case of Bleeding

Endoscopy with the identification of the bleeding site: active bleeding is identified by endoscopy or systemic hemoglobin values. Blood pressure and heart rate are recorded.

In Case of Suspected Perforation

Standard X-ray of the abdomen in upright and left semiprone position

Gas insufflation via a gastric tube may facilitate the diagnosis in conventional X-ray examination; in case of peritonism without direct evidence of free abdominal gas, a CT scan should be obtained.

Especially in retroperitoneal perforation of the duodenum, free gas may not be seen in standard X-ray films.

Procedure in Perforated Gastric Ulcers

 

 

 

 

STEP 1

Exposure of the ulcerative lesion

 

 

The ulcerative lesion is completely exposed. In case of perforation of the posterior

 

 

 

 

gastric wall, the omentum of the stomach and of the colon is separated, and the omental

 

bursa is exposed (see “Subtotal Gastrectomy” STEP 1, Fig. B).

 

 

 

 

STEP 2

Excision of the ulcer

 

 

In case of chronic granulation, the wall of the ulcer is excised longitudally.

Closure

STEP 3

Procedure in Bleeding Gastric Ulcers Refractory to Endoscopic Treatment

Gastrotomy and exposure of the bleeding site

In bleeding without perforation, gastrotomy is the exposure of choice. Use a longitudinal incision of the anterior gastric wall.

Isolation of the bleeding

In bleeding of the posterior gastric wall, verify that the source of bleeding might arise from an ulceration of the splenic artery. In this case, separate the artery at its origin and ligate it. Additional stitches placed around the ulcer wall on all four sides may help to control bleeding. The use of a non-absorbable suture is preferable. Collaterals maintain blood supply to the spleen, and splenectomy is not required.

Closure

Closure of the incision with the single layer technique.

SECTION 2

Esophagus, Stomach and Duodenum

 

 

 

 

Local Excision in the Duodenum

 

 

Introduction

 

In complicated duodenal ulcers, local excision is the therapy of choice. Depending on the localization and the extension, a duodenojejunostomy with a

Roux-en-Y reconstruction is indicated. Further, the gastroduodenal artery should be ligated in case of bleeding ulcers.

 

Indications and Preoperative Investigations

 

These correspond to those in gastric ulcers and bleeding (see “Local Excision in the

 

Stomach” above).

 

Procedure in Complicated Duodenal Ulcers

 

Ventral Duodenal Wall

 

 

STEP 1

Exposure of the duodenum

 

The duodenum is completely exposed and opened longitudinally.

 

 

In case of perforation, the ulcerative lesion is excised.

STEP 2

Closure of the incision

 

 

 

 

The incision is closed crosswise using single stitches. Kocher’s maneuver may lower the tension to the suture. Mind that the duodenal passage is not compromised. Depending on the extent of the excision, primary closure might not be advisable. In this case, a duodenojejunostomy is required using a Roux-en-Y reconstruction (A-1, A-2, A-3).

SECTION 2

Esophagus, Stomach and Duodenum

 

 

 

 

Posterior Duodenal Wall

 

 

 

 

STEP 1

Exposure of the duodenum

 

 

After exposing the duodenum, Kocher’s maneuver is performed, and the posterior wall

 

 

of the duodenum is completely exposed in case of perforation. In case of bleeding, the

 

anterior wall is opened, and single stitches are placed on all four sides of the ulcerative

 

lesion.

 

STEP 2

Excision of the ulcerative lesion

 

The ulceration is excised (see “Local Excision in the Stomach”, STEP 2). As a rule,

 

 

primary closure of the lesion may not be advisable, as mobilization of the posterior

 

duodenal wall is limited. Hence, a duodenojejunostomy is put in place. The gastro-

 

duodenal artery is exposed and ligated at its origin. In case of bleeding ulcers, this

 

step might be taken first, when the bleeding source has previously been identified in

 

gastroduodenoscopy.
