There is risk for encephalopathy as toxins are not adequately filtered. Definitive surgery ○ Types: Shunt surgeries - Bypassing liver parenchyma - i.e., portosystemic shunt, splenorenal shunt Non-shunt surgeries - Hassab’s procedure - Sugiura and fataura procedure, distal esophagectomy ○ Performed in patients with cardiac problems wherein TIPSS is not recommended or no specialist is available. Figure 2. Portal circulation Batch 2025 Trans on Surgical Disorders of the Esophagus 2. PORTAL HYPERTENSION If with cirrhosis (due to alcoholic liver disease, fatty liver or schistosomiasis), it would cause damage to parenchyma → obstruction in the portal vein → altered systemic blood flow → development of collateral vessels → coronary vein will go to Figure 4.

ACHALASIA ○ Other symptoms: ascites, jaundice, encephalopathy An esophageal disorder characterized by impaired motility and incomplete lower esophageal sphincter relaxation. It causes progressive dysphasia, regurgitation of food, and chest 🧠 pains. Gold standard for diagnosis: Esophageal manometry ○ Shows high pressure in the lower esophageal sphincter, incomplete lower esophageal sphincter relaxation, and 📝 decrease in esophageal peristalsis. Other motility disorders: ○ Diffuse Esophageal Spasm (DES) ○ Nutcracker Esophagus ○ Hypertensive Lower Esophageal Sphincter Most of the patients with motility disorder that go for surgery are patients with Achalasia. Achalasia results from the progressive degeneration of ganglion cells in the myenteric plexus in the esophageal wall Leading to failure of relaxation of the lower esophageal sphincter LES) accompanied by loss of peristalsis in the distal esophagus which consequently leads to esophageal dilatation. Patients with achalasia present with dysphagia, regurgitation and sometimes, chest pain Figure 3. Portal hypertension Batch 2025 Trans on Surgical Disorders of the Esophagus D.

Dor Fundoplication Dr. Bautista’s Video Lecture Doctor’s Notes Done by splitting of the muscles The cut is made proximally on the esophagus for 4-5 cm and distally over the stomach, 1 to 2 cm below the EG junction. In Figure 7. Manometry some books, it is up to 2.5 cm below the EG junction. Dr. Bautista’s Video Lecture C. COMPLICATIONS [BATCH 2025] MANOMETRY Related to tearing of the esophagus 1 Perforation - due to dissection of the mediastinum, there is a risk of perforation of the pleura 2 Pneumothorax 3 Bleeding 4 Vagus nerve injury - if accidentally transected during myotomy 5 Acid Reflux - if fundoplication is not done Figure 8.

Achalasia type III Myotomy of the LES can be performed via abdominal or thoracic ○ Spastic achalasia approach. ○ There are abnormal contractions of distal esophagus. Weakening of the LES via surgical myotomy is accomplished by cutting the muscle fibers of the cardia, where the LES is located. B. TREATMENT Focuses on reducing the pressure of lower esophageal sphincters, which can be accomplished by procedures that tear or cut the 📝 sphincter muscle or by medications. Reduction in LES resistance can be accomplished by: ○ Medical: botulinum Injection, oral use of nitrates ○ Endoscopic: pneumatic dilatation, peroral endoscopic myotomy (POEM) ○ Surgical: Heller Cardiomyopathy 1. HELLER CARDIOMYOTOMY Performed when conservative medical management fail to resolve Figure 11. Myotomy symptoms.

Fundus of the stomach may be wrapped fully or partially at the distal esophagus. Figure 20. Partial Fundoplication Most people who had a fundoplication enjoy a long lasting relief Dr Bautista’s Synchronous Session from the symptom of reflux. IV. HIATAL HERNIA When one part of the stomach slips through the diaphragm into the 🧠 middle compartment of the chest. GERD is a consequence of this condition. With the advent of clinical radiology, it became evident that a diaphragmatic hernia was a relatively common abnormality but not always detected as it is not commonly accompanied by symptoms. If present, it is also fixed during fundoplication. A. TYPES OF HIATAL HERNIA Type I: Classic Sliding Hiatal Hernia Figure 18. Fundoplication ○ Esophagogastric Junction is above the hiatus Dr. Bautista’s Video Lecture Type II: Paraesophageal or Rolling Hiatal Hernia ○ Esophagogastric Junction is at the level of the hiatus TYPES OF FUNDOPLICATION Type III: Mixed Hiatal Hernia COMPLETE FUNDOPLICATION (TOTAL) - 360° Type IV: Hiatal Hernia with Abdominal content ○ Done to patients with abnormal manometry ○ Worst ○ Contraindicated to patients who have other mobility disorders, ○ Whole stomach is herniated into the thorax or it can be better to to partial accompanied by other organs like transverse colon. PARTIAL FUNDOPLICATION - ○ Dor fundoplication - 180° ○ Toupet fundoplication - 270° If the graft is too tight, post-op patients produce symptoms of dysphagia [BATCH 2025] TYPES OF FUNDOPLICATIONS COMPLETE FUNDOPLICATION Nissen fundoplication: 360° complete fundoplication ○ Most surgeons perform a loose wrap that is about 2-3 cm in length followed by a posterior crural repair ○ The problem with Nissen fundoplication is sometimes, it is too tight so patients may present with dysphagia. In this case, partial fundoplication may be done instead. Figure 21. Types of Hiatal Hernia Dr Bautista’s Synchronous Session Group 6B | Surgical Disorders of the Esophagus 5 of 14 B.

If intra abdominal esophageal length cannot be achieved with esophageal mobilization alone, an esophageal lengthening procedure may be required. COLLIS GASTROPLASTY Collis gastroplasty is an esophageal lengthening procedure. This is followed by the closure of the hiatus either with primary repair alone or with a mesh. Figure 22. Diagnostics for Hiatal Hernia Left: EGD, Middle: Esophagogram, RIght: CT Scan Dr. Bautista’s Synchronous Session C. MANAGEMENT Surgical management is indicated when medical management fails to control symptoms such as GERD/Reflux, dysphagia, regurgitation anemia, dyspnea, and intermittent epigastric or abdominal pain. Patients with these symptoms can be repaired as electives. Emergency repair is required when there is a complication such as bleeding, obstruction, gastric volvulus, strangulation, perforation, or with respiratory compromise. The urgency is dependent upon the acuity of the presentation. Surgical repair is associated with improved symptoms and better Figure 24. Collis gastroplasty quality of life. Dr. Bautista’s Synchronous Session Table 1. Elective and Emergency Repairs Doctor’s Notes Usage of a mesh is still controversial due to complications of ELECTIVE REPAIR EMERGENCY REPAIR mesh that can erode to the surrounding tissues (ie: esophagus) Relaxing incisions in the diaphragm are done if the hiatus is too Reflux Bleeding wide to stretch so it can oppose it Dysphagia Obstruction Regurgitation Volvulus CLOSURE OF THE HIATUS The problem with placing a mesh (biologic or synthetic) is it can Anemia Strangulation lead to serious complications that would be needing operations. Dyspnea Perforation Complications include intraluminal mesh erosion, esophageal stenosis, and dense fibrosis. Epigastric Pain Respiratory Compromise Others suggest fundoplication afterwards.

These procedures reduce recurrence rates. Figure 29. Severe Subcutaneous Emphysema Dr. Bautista’s Synchronous Session Doctor’s Notes Patient’s face is puffy because the air formed within the esophagus escapes to the subcutaneous tissues Most morbid presentation of perforation is shock due to delayed management SPONTANEOUS PERFORATIONS Boerhaave’s Syndrome ○ Rarely, can occur spontaneously under tremendous stress ○ Usually happens during forceful and repeated vomiting Figure 27. Gastropexy by suturing ○ Accounts for only 15% of esophageal perforation. Dr. Bautista’s Synchronous Session Doctor’s Notes GASTROSTOMY TUBE PLACEMENT Presents with chest pain because the contents of the esophagus May also be done has leaked out Compared to the mallory-weiss tear (upper GI bleed), boerhaave is more on penetration 🧠 IATROGENIC Most common case Majority occur during medical procedures especially during endoscopy. Other procedures that can cause iatrogenic injury to the esophagus: ○ NGT insertion ○ Endotracheal intubation ○ Tracheostomy ○ Spine surgery ○ Etc. Rigid endoscopy usually causes perforation in the proximal esophagus. WHY IS ESOPHAGUS AT RISK FOR PERFORATIONS? Esophagus does not have an outer lining which is the serosa like Figure 28. Gastrostomy Tube most of the other organs, thus, this makes the esophagus more Dr. Bautista’s Synchronous Session vulnerable to rupture. It is especially more susceptible to rupture if the inner lining or the mucosa is inflamed or injured. Group 6B | Surgical Disorders of the Esophagus 7 of 14 Table 2. Factors Affecting Results A.

This happens when there is a presence of air trapped under the skin in the Because of these factors, the diagnosis should not strongly rely subcutaneous tissue. This condition is more commonly seen in on the x-ray findings. airway perforations such as tracheal perforations. The diagnosis is confirmed with the contrast esophagogram which shows extravasation in 90% of patients. The use of water-soluble contrast gastrografin is preferred over barium and is less toxic. 1. ESOPHAGOGRAM If a perforation is expected, an esophagogram is requested to locate the perforation. Perforation is demonstrated by the extravasation of dye through the rupture. Figure 30. Chemical inflammation or pleurisy of the lining of the chest cavity Dr. Bautista’s Video Lecture Figure 33. Esophagogram Dr. Bautista’s Video Lecture Extravasation of dye through the rupture (black arrow) 2. CT SCAN May also be requested This can help find pockets of leaked dye and fluids that would need draining and repair of the surrounding tissues. Figure 31.

Figure 42 Open approach or MIS Dr. Bautista’s Video Lecture ESOPHAGECTOMY In extreme cases, when the esophagus cannot be repaired. Figure 39. Diversion Dr. Bautista’s Synchronous Session 4. OTHER PROCEDURES Based on the severity of perforation and clinical findings, a number of procedures can be performed including: Figure 43. Esophagectomy Dr. Bautista’s Video Lecture DRAINAGE OF SPILLED FLUIDS AND FOOD WITH CHEST TUBE Since this is too technical, just remember the importance of prompt diagnosis. Dr. Bautista D. PROGNOSIS Esophageal perforation is survivable but the prognosis depends on how soon the treatment is received. The more time the infections have spread from the perforation through the chest and into the bloodstream, the higher the risk. Those who received treatment within the first 24 hours of perforation are likely to make a full recovery. VI. TRAUMA: CAUSTIC INGESTION Caustic ingestion is mainly accidental in children and rather in small quantities. Figure 40. Chest Tube Dr. Bautista’s Video Lecture On the other hand, in adults or teenagers, the swallowing of caustic liquid is usually deliberate during a suicide attempt and greater quantities are swallowed.

A. ALKALI Alkalis are more frequently swallowed accidentally than acids because strong acids cause an immediate burning pain in the mouth. Alkalis dissolves tissue by causing liquefactive necrosis where it penetrates tissue more deeply. Alkalis: sodium and potassium hydroxide ○ Drain cleaners ○ Household cleaning products ○ Lye ○ Disc battery B. ACIDS Figure 41. Endoscopy and stent placement Acids cause coagulative necrosis that limits their penetration. Dr. Bautista’s Video Lecture Acids: hydrochloric acid, sulfuric acid, and phosphoric acid ○ Toilet and swimming pool cleaners ○ Anti-rust compounds ○ Battery fluid Group 6B | Surgical Disorders of the Esophagus 10 of 14 C. SEVERITY AND EXTENT OF INJURY ○ CT evidence of transmural necrosis The severity and extent of esophageal and gastric damage ○ Perforation of esophagus and or stomach resulting from caustic ingestion depends upon the following During the exploratory laparotomy, all transmural necrotic tissues factors: should be resected. A second look operation may be required for patients with 1 The nature of the caustic substance suspected ongoing necrosis. Alkali produce more damage than acid When there is extensive gastric involvement, the esophagus is nearly always necrotic or severely burned. Therefore 2 Concentration and amount ingested esophagogastrectomy thru a combined abdominal and The higher the concentration of the substance and the larger cervical incision is always performed the amount of substance ingested, the more likely it will cause an esophageal injury. 1.

Prompt diagnosis and management is critical to minimizing mortality. A primary repair is the gold standard of care and should be utilized for perforations of the thoracic and abdominal esophagus, as well as for visualized perforations of the cervical esophagus.

RATIONALIZATION 4 CORRECT ANSWER: C. Achalasia No. RATIONALIZATION Patients with achalasia present with dysphagia, regurgitation 1 CORRECT ANSWER: B. Fundoplication and sometimes, chest pain. The diagnosis of achalasia shows a Bird’s Beak Appearance (Fig 1) confirmed by barium swallow This is a case of GERD. First line treatment consists of lifestyle appearance. While manometry is able to confirm if there is modification and medications. Surgical management (antireflux hypertensive lower esophageal sphincter (LES) and to classify surgery) is reserved for patients who have persistent symptoms achalasia type. or developed complications despite optimal medical therapy. Fundoplication is the more commonly performed antireflux A is incorrect because Boerhaave’s Syndrome is a type of procedure. The primary goal of antireflux surgery is to safely perforation. It is a spontaneous perforation which is considered create a new antireflux valve at the gastroesophageal junction a fatal condition that is caused by forceful vomiting and (GEJ) while preserving the patient’s ability to swallow normally, accounts for only 15% of esophageal perforation. and to belch to relieve gaseous distention. B is incorrect because Paraesophageal Hernia is a hiatal The new valve created by the wrap should be tight enough to hernia. It is a type II known as Paraesophageal or Rolling Hiatal prevent regurgitation of gastric contents into the esophagus but Hernia. The esophagogastric Junction is at the level of the loose enough to relax on deglutition and respond to the hiatus. changes in intra-abdominal pressure. D is incorrect because Gastroesophageal reflux disease is an Ratio Batch 2025 inflammatory disease that develops due to reflux of gastric contents. While achalasia is a motility disorder characterized by 2 CORRECT ANSWER: C. Esophageal varices esophageal aperistalsis and nonrelaxation of the LES Esophageal varices are dilated collateral veins resulting from Ratio Batch 2025 increased blood flow due to portal hypertension, often caused by cirrhosis. Screening is usually done with EGD and is 5 CORRECT ANSWER: A. Barium Swallow recommended at the time of cirrhosis diagnosis. The patient presents with achalasia, the most common There are two (2) types of varices: 1) non-bleeding, which are esophageal motility disorder of the lower esophagus. This typically asymptomatic, and 2) bleeding varices which are condition is associated with dysphagia, regurgitation and composed by sudden onset of severe symptoms of GI bleeding sometimes, chest pain. The non-relaxing lower esophageal (such as: hematemesis, hematochezia, and melena). sphincter that results from this condition causes a functional retention of ingested materials in the esophagus which leads to In the case of the patient, he was diagnosed to have cirrhosis a sensation of obstruction of food in the chest. and had an episode of massive hematemesis which led to an ER consult.
