Fig. 26 Demonstrates the technique of cervical esophagogastric anastomosis. (a) Shows silk stay sutures in place with the esophagus and stomach aligned for anastomosis. (b) Shows the GIA sta­pler in positioned pointed towards the patient’s right ear. (c) Shows completion of the posterior stapled anastomosis, the anterior wall is then closed with interrupted 5-0 vicryl suture
Postoperatively, nasogastric feeds are initiated and the patient is kept NPO through post-operative day 5 when an esophagram is performed. After which, the nasogastric tube is removed and the patient advanced to a mechanical soft diet after evaluation with the speech therapy team.
Our high volume group has shown repeated good success with this technique with a leak rate of less than 10% over an 8year period in 130 patients [22], all of whom were managed conservatively with success. No postoperative mortalities were contributed to leak. Furthermore, leaks were associated with patients with chronic obstructive pulmonary disease, and previous gastric surgery such as previ­ous fundoplication or metabolic surgery.
15 McKeown (Three-Hole) Esophagectomy
Three incisions are required for the McKeown technique: a right thoracotomy, an upper midline laparotomy, and a left neck incision. The right chest is entered rst to carry out mobilization of the intrathoracic esophagus and mediastinal lymphade­nectomy. Once the esophagus has been mobilized, the chest is closed without divid­ing the esophagus. The patient is then placed in the supine position and the remainder of the procedure is carried out in similar fashion to the THE.However, blunt medi­astinal dissection is not required, as the intrathoracic esophagus has already been completely mobilized.
The McKeown esophagectomy has both the advantages and disadvantages of the ILE and THE.An additional incision increases the chance of wound complications and increased postoperative pain. A unique advantage to this technique is that pathology at any level can be addressed. Our group prefers this approach with

mid- esophageal squamous cell cancers. We nd that these lesions typically require more direct dissection, especially since many squamous cell lesions come to sur­gery late after failures of denitive chemoradiation strategies.
16 Sweet or Left Thoracoabdominal Esophagectomy
The Sweet technique utilizes a left thoracoabdominal incision and neck incision for creation of a cervical anastomosis, as the aortic arch prevents creation of a high intrathoracic anastomosis. This technique is rarely employed today, and is included in the chapter for historical interest. The patient is positioned in a modied right lateral decubitus position with the abdomen and hips tilted slightly posteriorly. Left lung is isolation is required. The incision extends from just below the scapular tip, along the 6th or 7th intercostal space, across the costal margin, and then obliquely onto the upper abdomen in a paramedian fashion. The abdominal portion of the inci­sion is made rst and once resectability is conrmed, the thoracotomy is made and the incisions are connected by sharply dividing the costal margin. The diaphragm is incised circumferentially for 8–10cm, leaving a 2cm cuff for closure. This excel­lent exposure allows for completion of both the abdominal and chest stages through a single incision. After resection, the conduit is passed beneath the aortic arch and the cervical stage with a cervical anastomosis is completed. The diaphragm is closed and the costal margin is reapproximated with gure-of-eight sutures. The thora­coabdominal incision is then closed in layers after drains are placed.
The Sweet esophagectomy is ideal for locally advanced distal esophageal tumors, such as tumors invading the diaphragmatic hiatus, as this wide exposure provides optimal access to the hiatus and gastroesophageal junction (Fig.27). The main dis­advantages of this technique include increased postoperative pain owing to the large incision, as well as risk of costal arch dehiscence and diaphragm dysfunction.

17 Colon Interposition Esophagectomy
Many clinical scenarios exist which may render the stomach an unsuitable or unavailable conduit to restore continuity after esophagectomy. Such scenarios include previous esophagectomy resulting in leak or conduit necrosis which neces­sitated conduit resection or returning the conduit to the abdomen. Others include caustic ingestion with injury to the esophagus and stomach, previous gastrectomy, history of redo fundoplication, or more commonly the patient status post metabolic surgery [23]. Particular challenges come with the patient after sleeve gastrectomy, as the typically used lumen of the greater curvature of the stomach has been resected, and the main conduit blood supply of the gastroepiploic arcade has been disrupted.
When the traditional gastric conduit is not available, alternatives include colon, small bowel and myocutaneous grafts. The colon conduit being the most preferred and frequently used in this case [24]. Many considerations must be taken during a patients’ workup for candidacy. All undergoing colon interposition esophagectomy must have a colonoscopy, and mesenteric vessel mapping during workup by CT angiography and/or conventional angiography (Fig.28). Our group routinely obtains both imaging methods, as we nd that conventional angiography gives great dynamic detail regarding the left colon and the presence of the Arc of Riolon, mar­ginal artery of Drummond, or if a meandering artery/artery of Moskowitz is present. Contraindication to the use of colon as a conduit include previous diverticulitis, family colon cancer pathologies and personal history of inammatory bowel dis­ease, among others. Whether the right or left colon is used for replacement is of some debate. There are some relative guides as seen in Table1, but much is also left to determination and comfort of the surgical team. The patients undergo a mechani­cal and antibiotic bowel prep the evening before surgery.
The operative approach is done via laparotomy and left neck incision as a tran­shiatal approach. When the right colon is used, its vascular supply is based off the middle and left colic arteries [25]. First, a complete right medialization of the colon

along the white line of Toldt is performed. Bulldog vascular clamps are placed at the origin of the ileocolic artery and other branches of the right colic artery at their future transection sites and non-crushing bowel clamps are placed at the ileocecal junction and along the transverse colon between the right and left branches of the middle colic artery. Adequate blood supply is conrmed with subjective color change of the bowel, intact doppler ow within the terminal branches of the right colon mesentery, and indocyanine green uorescence imaging (Fig.29). After con­rmation of adequate blood supply, the bowel and vascular pedicles are divided at the above-mentioned locations. An appendectomy is performed. A mediastinal mobilization is then performed either in the posterior mediastinum with esophagec­tomy should the organ be in-situ or an anterior mediastinal tunnel if an esophagec­tomy was already been performed and the posterior mediastinum scarred down. If the anterior mediastinum used, some authors will resect the medial aspect of the left clavicle to prevent luminal impingement and venous outow obstruction [26]. The right colon is brought through the mediastinum in an antiperistaltic fashion. The proximal esophagus is anastomosed to the cecum with the linear staple technique as described in our above transhiatal approach. The proximal transverse colon of the conduit is anastomosed to the proximal gastrointestinal tract and an ileocolic anas­tomosed done, thus restoring gastrointestinal continuity. A jejunostomy tube is placed.
If the left colon is used, the blood supply is based off the inferior mesenteric artery via the marginal artery of Drummond. The left colon and splenic exure are completely medialized, with preservation of the ureter. The blood supply is assessed in a similar manor of non-crushing clamping, doppler and indocyanine green uo­rescence assessment as described above. Here the distal sigmoid colon and trans­verse colon between the middle and left branches of the middle colic artery are

clamped as is the middle colic artery and then divided assuming adequate perfusion. As described above the mediastinum is dissected. The left colon is brought through the mediastinum in an isoperistaltic orientation. Anastomoses are performed simi­larly as described above.
A Jackson Pratt drain is placed in the left neck and nasoenteric tube positioned in the conduit. Post operatively, the patient is admitted to the surgical intensive care unit. Jejunostomy feeds are initiated on postoperative day 2. A video esophagram is obtained on day 5 to evaluate for leak—if negative, the nasoenteric tube is removed and the patient is advanced to a mechanical soft diet with the assistance of the speech therapy team.
18 Conclusions
Esophagectomy is a complex, multistep, multidisciplinary procedure with multiple resection techniques. The approach to each patient must be individualistic depend­ing on the patients’ pathology the surgeons’ expertise.

1 Indications
There are several pathologies that may require splenectomy, ranging from autoim­mune disorders, benign or malignant hematologic disorders, vascular disorders, benign or malignant splenic masses and traumatic splenic rupture (Table 1) [1]. Immune idiopathic thrombocytopenia remains the most common elective indication for splenectomy. First-line treatment in these patients is glucocorticoids, but only 40% will have a response to treatment and only 50% of those responders will have

a sustained response [2]. With the development of immunologic therapy, the role of splenectomy for ITP may become more limited [3]. Patients with hereditary sphe­rocytosis often undergo a splenectomy in childhood to decrease transfusion require­ments, skeletal abnormalities and formation of bilirubin gallstones [4]. While many of the other benign and malignant hematologic diseases are treated medically, sur­gery may be indicated in the setting of refractory pancytopenia, constitutional symptoms, abdominal pain, and/or early satiety [1]. Absolute contraindications to the laparoscopic approach include hemodynamic instability, inability to tolerate insufation, uncontrolled coagulopathy, severe cardiopulmonary disease, cirrhosis with portal hypertension, and pregnancy. Relative contraindications may include massive splenomegaly, prohibiting placing the specimen in an extraction bag, and multiple prior abdominal surgeries. It is important to note that, while the role is limited, there may be a subset of traumatic splenic injuries that are appropriate for management with laparoscopic splenectomy. This may be considered if the patient remains hemodynamically responsive to transfusion but nevertheless requires ongo­ing transfusions, with no concern for other intrabdominal injuries, likely in a facility without interventional radiology availability [5].
N. Lunardi and H. B. Prince
2 Preoperative Preparation
There are several important considerations in the preoperative history, physical and evaluation for an elective laparoscopic splenectomy. Patients should be asked about symptoms specic to a personal or family history of splenomegaly (abdominal pain, early satiety), benign/malignant hematologic disease (constitutional symptoms, fatigue, coagulopathy), cirrhosis or liver failure, recent trauma, and/or infectious processes. Patients should be asked if they are on glucocorticoids (dose and length of treatment) to assess the need for intra- and post-operative stress-dose steroids. On physical exam, stigmata of portal hypertension, liver failure and splenomegaly should be assessed. If not done already, a hematologist should be involved in the evaluation for hematologic, immune and myeloproliferative disorders, which may include peripheral blood smears and bone marrow analysis. Their input is essential in anticipating the pre-operative and intra-operative transfusion requirements. They may also suggest pre-operative intravenous immunoglobulin for thrombocytopenic patients.
A valid type and screen will be essential for the operation should the need for transfusion arise. Pre-operative imaging with a CT abdomen/pelvis with intrave­nous contrast will help identify the size and anatomy of the spleen, accessory spleens, splenic vasculature and the surrounding structures. Other imaging modali­ties have limited role in preoperative planning, including ultrasound for portal hypertension and MRI for solid peri- or intra-splenic tumors. Preoperative splenic artery embolization could be considered in the case of massive splenomegaly or portal hypertension. This will decrease intraoperative blood loss and decrease the

technical difculty of splenic mobilization [6]. Patients undergoing a splenectomy will need vaccinations for encapsulated organisms (Hemophilus inuenza B, Streptococcus pneumoniae, Neisseria meningitides) to prevent a post-operative overwhelming post-splenectomy infection (OPSI) [7].
267
3 Positioning andAnesthesia
It is vital to anticipate and communicate transfusion and stress dose steroid require­ments with your anesthesia colleagues. Antibiotic and deep venous thrombosis pro­phylaxis should be given 1h prior to skin incision. When the patient is placed on the operating room table, sequential compression devices should be applied and all pressure points should be padded. After general anesthesia is administered and the airway is secured, a nasogastric or orogastric tube should be placed to decompress the stomach to improve intraoperative visualization. A foley catheter may be placed based on surgeon and anesthesia discretion.
The patient can be positioned in the supine, right lateral decubitus, or anterolat­eral positions. Each position has its benets and drawbacks. You may consider the supine position, if the patient has massive splenomegaly to improve visualization of the hilum or if you are doing other intrabdominal procedures. However, in the right lateral decubitus or the anterolateral positions, you can use a beanbag or ex the table to increase the space between the costal margin and iliac crest. By doing so, you maximize visualization and ease the difculty of dissection for most cases. It is important to note, conversion to an open procedure is easiest from the supine posi­tion and most difcult from the right lateral decubitus position. In all patient posi­tions, be careful to maintain the spine, extremities, and shoulders in a neutral position.
4 Description ofProcedure
4.1 Abdominal Access
There is no singular superior technique of gaining intrabdominal access for a lapa­roscopic splenectomy (OptiView, Veress Needle, Hasson Technique, etc). It is our practice to use a Veress needle at Palmer’s point in the left upper quadrant. Intrabdominal position is conrmed with a saline drop, aspiration of non-gastric/ bilious uid, and a starting insufation pressure of around 8mmHg. At that point, insufation is initiated until a pressure of 15mmHg is obtained.
A 5mm port in placed in the left upper quadrant just inferior to the costal margin in the anterior axillary line. A laparoscope in inserted and the abdominal cavity is
268
https://t.me/med1917
inspected for injury from the Veress and trocar placement. Once it is veried no injury has occurred, the Veress needle is removed under direct visualization. The remaining ports are placed under direct visualization: 10mm supraumbilical cam­era port, 5mm sub xyphoid, and 12mm left lower at the midaxillary line (PICTURE).

4.2 Mobilization ofSplenic Ligaments
Dissection begins with the splenocolic ligament. The splenic exure of the colon should be retracted inferiorly. Using traction and countertraction, the splenocolic ligament is identied and divided using sharp dissection and electrocautery. If there are omental attachments, there may be accessory vessels which should be divided using a bipolar electrocautery. This dissection is continued laterally moving cepha­lad towards the splenophrenic ligament. By doing so, the posterior hilum is being exposed. The splenophrenic ligament should not be divided at this point as it can help with maintaining visualization of the hilum.
4.3 Devascularization oftheSpleen
At this point, attention should be turned medially. To enter the lesser sac, the greater curvature is grasped at the level of the inferior pole of the spleen and retracted ante­riorly and to the patient’s right. The short gastric vessels should be divided using bipolar electrocautery in a stepwise fashion moving cephalad until the left crus of the diaphragm is visualized. The anterior surface of the pancreas, splenic hilum with the splenic artery and vein should be visualized. The splenic artery runs inferior and anterior to the vein. Once the vascular pedicle is circumferentially dissected using blunt dissection and electrocautery, an endovascular vascular stapler is used to divide the artery and vein en masse. Prior dogma suggested diving the artery and vein together would lead to an arteriovenous stula; however, it is acceptable, and therefore our practice, to take the structures together using a vascular stapler. It is important to note additional vascular staplers maybe required to divide splenic vein branches along the medial margin of the spleen. At this point, spleen should be completely devascularized.
4.4 Inspecting forInjury andRemoving theSpecimen
The tail of pancreas should be carefully inspected for possible pancreatic injury. Any concern for injury should prompt placement of a 15Fr blake drain to monitor and control any possible pancreatic stula. The splenophrenic ligament should now be divided, unless the attachment would assist in placing the specimen in an extrac­tion bag. The extraction bag is placed in the abdomen via the 12mm port. Once the
