Step16
Preparation of a substernal tunnel
A blunt opening is made in the substernal cavity by spreading the scissors, while retracting the xiphoid ventrally with a sharp retractor (
Aer opening the substernal cavity, a substernal tunnel is constructed with an atraumatic
clamp.
e sternum has to be retracted anteriorly, and the endothoracic membrane is to be separated from the sternum. A longitudinal incision along the anterior border of the le sternocleidomastoid muscle is made to expose the cervical esophagus. Blunt preparation with the hand through the substernal tunnel usually leads to rupture of the mediastinal pleura (

Completed preparation of the retrosternal tunnel
In case of tight adhesions to the sternum, these adhesions are dissected sharply with scissors.
Between the corpus and the manubrium sterni the substernal fascia is very tightly connected to the sternum. Furthermore, the visceral and parietal pleura are tightly connected in this region. For this reason, very careful, stepwise preparation with a long atraumatic clamp has to be per­formed, and the preparation should be manually controlled by the substernally introduced nger of the surgeon (
. Fig. 25.13).

Step18
Pull-through procedure
For the substernal reconstruction, a long strong suture is passed from the cervical incision through the mediastinal tunnel and into the abdomen to facilitate the pull-through procedure. e suture is tied to the oral end of the colonic interposition. e colon is transposed in the substernal tun­nel to the cervical incision under a continuous and gentle pull, and the sternum should be pulled upward with a sharp retractor during the procedure (
. Fig. 25.14).

Posterior mediastinum
Interposition of the colon through the posterior mediastinum is performed in the bed of the removed esophagus. e posterior mediastinal route of the colonic interposition is favorable to the substernal or presternal position because of the shorter distance to the neck. In addition, the posterior mediastinal route prevents kinking of the colon and leads to better functional results. e interposed colon causes hemostasis in the operative eld (

End-to-side anastomosis
If possible, the esophago-colonic or pharyngo-colonic end-to-side anastomosis should be per­formed in a double-row suture technique.
In case of a dierent lumen diameter, interrupted stitches and a end-to-side anastomosis can be performed close to the tenia coli (
. Fig.25.16

Reconstruction of the intestine
Gastrointestinal continuity is achieved by cologastrostomy.
A colosigmoidoscopy completes the reconstruction. e mesenteric incisions have to be closed. e operative site aer transposition of the colon and reconstruction is shown (. Fig. 25.18).

Tricks of the Senior Surgeon
Treatment of the stenosis is performed by bougienage or balloon dilatation. Very rarely is
-
surgical intervention indicated.
Reasons for necrosis of the interposition are decrease of circulation due to kinking or com-
-
pression of the main vessels, hypovolemia, and hypercoagulability. Avoidance is by interposi-
tion of a long colonic segment without tension. Optimization of the postoperative hemody-
namic and rheologic parameters is necessary.
Kinking of the interposition is a rare but dangerous complication, which often requires surgi-
-
cal intervention, due to clinical symptomatic diculty with emptying of the colonic conduit
by elongation of the interposition. Surgical intervention is performed by shortening of the
graft.
To avoid herniation of bowel into the pleural cavity, the diaphragmatic hiatus has to be
-
closed.

Extended Gastrectomy

Asad Kutup, Jakob R. Izbicki
Clinical TNM staging and an evaluation according to the adenocarcinoma of the esophagogastric junction (AEG) classication in TypeI (esophagus), Type II (cardia), and TypeIII (subcardia) form the basis for an individualized surgical treatment of AEG. Endoscopic resection is only appropriate for the infrequent mucosal carcinomas whereas the majority of the junctional carci­nomas are treated by surgical resection. A TypeI carcinoma is removed by radical transthoracic en-bloc esophagectomy with high intrathoracic esophagogastrostomy or by the transhiatal esopha­gectomy. In case of TypeII or III carcinomas, a transhiatal extended gastrectomy including distal esophageal resection is performed with reconstruction by Roux-en-Y esophagojejunostomy in the lower mediastinum. However, some advanced TypeII carcinomas, which cannot be resected R0 at the esophagus, need a total esophago-(hemi-)gastrectomy with colon interposition. is surgical strategy is justied by the topography of the lesion and the corresponding lymphatic drainage. Neoadjuvant treatment should be considered in cT3 and cT4tumors.

Exposure of the esophagogastric junction
Aer lymphadenectomy of the celiac trunk, the lymphatic dissection is continued along the ce­liac trunk to the upper para-aortic region. Lymphatic tissue thus remains adherent en bloc with the lesser curvature and is later resected en bloc with the specimen. e abdominal esophagus is mobilized and caudal traction is applied with a so rubber tubing like a Penrose drain. For better exposure of the esophageal hiatus and the para-aortic region, the diaphragmatic crura are incised and the stumps are ligated. During this maneuver connective tissue between esophagus, the diaphragmatic crura, and the abdominal aorta must be removed carefully. us the diaphrag-

Exposure of the distal esophagus
For a better exposure of the distal esophagus, the diaphragm is incised up to the inferior le phrenic vein. Transection and suture ligation of the le phrenic inferior vein are performed. Inci­sion of the diaphragm up to the central portion is done (. Fig. 26.2)

Mobilization of the distal esophagus
Insert Mikulicz retractors, which are pulled upward to the le and right. Dissection starts with sharp dissection at the anterior esophageal surface to separate the diaphragm and pericardium from the esophagus (
To the right and le, the pleural cavity is incised and the parietal pleura are removed en bloc with the specimen. e esophagus is pulled caudally and the lateral esophageal ligaments consist­ing of branches of the vagal nerves, pulmonary ligaments, and esophageal branches are transected carefully between clamps or clips. Some surgeons prefer to use an energy device to ligate these connections. (
Mobilization of the region posterior to the esophagus including paraesophageal lymphatic tissue from the aorta and paravertebral fascia up to the tracheal bifurcation is done sharply and under vision (
