Laparoscopic Esocardiomyotomy-Risk Factors and Implications of Intraoperative Mucosal Perforation.

BACKGROUND: Mucosal perforation during laparoscopic esocardiomyotomy is quite frequent, and its consequences cannot always be neglected. The purpose of the study is to investigate the risk factors for intraoperative mucosal perforation and its implications on the postoperative outcomes and the functional results three months postoperatively. MATERIAL AND METHODS: We retrospectively identified the patients with laparoscopic esocardiomyotomy performed at Sf. Maria Hospital Bucharest, in the period between January 2017-January 2022 and collected the data (preoperative-clinic, manometric and imaging, intra-and postoperative). To identify the risk factors for mucosal perforations, we used logistic regression analysis. RESULTS: We included 60 patients; intraoperative mucosal perforation occurred in 8.33% of patients. The risk factors were: the presence of tertiary contractions (OR = 14.00, 95%CI = [1.23, 158.84], p = 0.033206), the number of propagated waves ≤6 (OR = 14.50), 95%CI = [1.18, 153.33], p < 0.05), the length of esophageal myotomy (OR = 1.74, 95%CI = [1.04, 2.89] p < 0.05), the length of esocardiomyotomy (OR = 1.74, 95%CI = [1.04, 2.89] p < 0.05), and a protective factor-the intraoperative upper endoscopy (OR = 0.037, 95%CI = [0.003, 0.382] p < 0.05). CONCLUSIONS: Identifying risk factors for this adverse intraoperative event may decrease the incidence and make this surgery safer. Although mucosal perforation resulted in prolonged hospital stays, it did not lead to significant differences in functional outcomes.

Management of Esophageal Perforations During Achalasia Treatment Experience of the General and Esophageal Surgery Clinic, Sf Maria Hospital.

Introduction: Achalasia is a motility disorder characterized by the absence of optimal relaxation of the lower esophageal sphincter (LES) with swallowing and lack of peristalsis of the esophageal body. Excepting temporary medical options, the treatment aims to lower the LES pressure by endoscopic or surgical means. Either method involves a risk of perforation. We analyzed the management of esophageal perforations in patients who received treatment for achalasia. Material and Method: we conducted a retrospective study of patients with achalasia hospitalized and treated in the Clinic of General and Esophageal Surgery within the Sf. Maria Clinical Hospital in Bucharest between January 2016 and December 2021. Results: There were 57 patients, 35 men, with a mean age of 50 years and a mean duration of symptoms of 35 months. Almost all (91.89%) patients presented with dysphagia. Preoperative manometry was performed in 52 patients, of whom 17 were type I, 35 were type II. The treatment was laparoscopic Heller eso-cardiomyotomy (LHM) in most cases (55), with Dor anterior fundoplication. There were 10 recurrent cases after dilation or surgery in another medical unit. There were 3 mucosal perforations after LHM. The treatment varied from simple suture to a combined endoscopic and surgical approach, involving the use of esophageal stent, abscess drainage, and feeding jejunostomy. We also present the management of two cases of esophageal perforation after endoscopic dilation, in which the support of the surgical team was necessary. Conclusion: Esophageal perforation in the treatment of achalasia, either endoscopic or surgical, requires immediate identification and treatment to provide the best chance of favorable evolution. The treatment of achalasia is indicated to be performed in dedicated centers, prepared even in case of complications.

Early Postoperative Complications of Thoracic Esophageal Diverticula: A Review of 10 Cases from "Saint Mary" Hospital, Bucharest, Romania.

Introduction: Thoracic esophageal diverticulum is a rare pathology frequently associated with esophageal motility disorders. Surgery is the only option in patients with severe symptoms. METHOD: This is a retrospective case series study of 10 patients who underwent diverticulectomy for thoracic (epiphrenic or mid-esophageal) diverticula. It was recorded: main preoperative symptoms, usual blood tests, barium swallow, upper endoscopy and esophageal manometry. We analyzed the postoperative complications, length of stay in hospital and intensive care unit. Results: Most patients presented with regurgitation and/or dysphagia. The surgical approach was through left thoracotomy or abdominal for epiphrenic diverticula and through right thoracotomy or thoracoscopy for mid-esophageal diverticula. 4 patients had severe complications: 3 had major leaks (one death) and one had chylothorax. DISCUSSIONS: Surgery for thoracic diverticula is associated with high mortality and morbidity rates. Leak from the suture line is the most common complication, unlike chylothorax which is a rare complication. Conclusions: Thoracic diverticula represent a benign pathology which can have "žmalignant" postoperative complications. A thorough preoperative work-up is mandatory for choosing the appropriate surgical technique. Use of multiple cartridges for stapling suture increase the risk of leakage, but oversewing the suture may diminish it.
