Phrenoesophageal Ligament Reconstruction With Mesh

Diagnosis of GERD, esophagitis, and hiatus hernia:

Preoperative diagnosis We will use the GERD-Health-Related Quality of Life (GERD-HRQL) questionnaire to evaluate symptoms of GERD [11]. Preoperative assessment to diagnose HH by upper GIT endoscopy and a barium meal test in reverse Trendelenburg position. The Los Angeles system will be used for grading esophagitis [12]. 24 pH and esophageal manometry will be used to assess the esophageal motility and esophageal PH

Surgical technique:

Under general anaesthesia, Alinasser's Technique of LHHR will be carried out in the Frensh position. The pneumoperitoneum was created with CO2 pressures as high as 15 mmHg.

Procedure Position. The patient is positioned the French position, the surgeon stands in-between the legs and the assistants stand on either side of the patient, Steep reverse Trendelenburg positioning is often required. Port placement. We use a standard ports placement for most foregut procedures performed.

This consists of establishment of pneumo-peritoneum using a Veress needle placed at Palmer's point in the left upper abdomen. An 10-mm optical trocar is inserted in the left subcostal position.

Additional ports are placed under direct vision as follows (Figure 1):

• Camera port (10 mm) in epigastric position (midway between the xiphoid process and the umbilicus.
• Assistant (5 mm) port at the left anterior axillary line below the costal margin.
• Surgeon's left hand port (5 mm) in right upper quadrant at the midclavicular line.

• Expose the diaphragmatic hiatus by retracting the left lateral segment of the liver.
• Reduce stomach and hiatal hernia sac by mobilizing the gastric fundus. Dissection begins with takedown of short gastric vessels and proceeds toward the diaphragmatic hiatus to fully expose the left diaphragmatic crus.
• Complete circumferential dissection of the hiatal hernia sac at the level of diaphragmatic hiatus. It is often easiest to gain entry into the proper plane immediately adjacent to the left crus. The correct plane is bloodless and involves division of loose areolar attachments. The right crus is approached by dividing the pars flaccida and dissected until the left crus is visualized. It is important to preserve the integrity of the crura during this phase of the dissection.
• The mediastinal dissection continues in a cranial direction to obtain enough intraabdominal esophageal length (minimum 3-5 cm).
• A non-absorbable mesh (≈2.0 x 10.0 cm) is sutured to the esophagus, just above the hiatus by four 2-0 prolene stitches. The continuity of the mesh is then fixed just below the hiatus anteriorly on the diaphragm by four 2-0 prolene stitches. About half of the mesh is fixed to the esophagus and the other half is fixed to the diaphragm.
• Re-approximation of the diaphragmatic crura is performed posterior to the esophagus using interrupted 0 non-absorbable sutures. A calibration tube is used to judge the approximation limit.
• If there is no space for mesh fixation on the diaphragm, the left hepatic triangular ligament will be released.
• Toupét fundoplication fashioned by positioning of the fundus posterior to the esophagus.

Three Interrupted 2-0 sutures are then used to anchor the stomach to the lower esophagus antero-laterally. Then, the left gastric segment is sutured to the esophagus antero-laterally, leaving a gap of 1.5 to 2 cm from the right gastric segment, completing a 270° wrap.

• The wrap is then anchored to the hiatus using interrupted 2-0 non-absorbable sutures.

Typically, four sutures are required to anchor the wrap to both the right and left crura as well as the anterior aspect of the diaphragmatic hiatus. The routine postoperative Care is achieved The Primary Outcome is the recurrence rate of hiatal hernia, as assessed by Endoscopy and imaging studies (e.g., barium meal in Trendelenburg position or endoscopy) at 1-2 years follow-up. Secondary Outcomes are the complication rates (e.g., dysphagia, mesh erosion, infection), Operative time, patient satisfaction and quality of life, hospital stay, readmission rate, Reoperation rate, Symptom improvement (e.g., reflux, chest pain), and coast Postoperative management Every day, vital signs such as heart rate, blood pressure, oxygen saturation, and intravenous fluid levels will be documented. Clear oral fluid will be initiated six hours after surgery. In the absence of any formal complaints, patients will be allowed to be discharged from the hospital. Follow up There are scheduled follow-up appointments at1,3,6,12, and 24 months postoperatively. The follow-up consisted of a clinical evaluation including presence of symptoms of GERD (heartburn, regurgitation, epigastric discomfort) or nonspecific symptoms such as dysphagia or vomiting), upper GIT endoscopy, radiographic barium meal in trendlenberge position and abdominal CT for selected patient. Statistical analysis For categorical variables, we utilized percentages and numbers as descriptive statistics, whereas for continuous variables, we used mean and standard deviations. The statistical analyses were conducted using SPSS 26 (SPSS Inc., Chicago, IL, USA).
