Results of the surgical treatment of non-advanced megaesophagus using Heller–Pinotti's surgery: Laparotomy vs. Laparoscopy

Abstract: INTRODUCTION:Dysphagia is the important symptom in achalasia, and surgery is the most common treatment. The Heller–Pinotti technique is the method preferred by Brazilian surgeons. For many years, this technique was performed by laparotomy, and now the laparoscopic method has been introduced. The objective was to evaluate the immediate and long‐term results of patients submitted to surgery by either laparotomy or laparoscopy.MATERIALS AND METHODS:A total of 67 patients submitted to surgery between 1994 and 2001… Show more

“…3 It is caused by the protozoon Trypanossoma cruzi and it could be associated with megaduodenum, megacolon, and megaesophagus. 4 Another acquired condition for megaduodenum could be systemic sclerosis. Patients with megaduodenum typically present themselves with upper GI symptoms like sensation of ever-increasing fullness of the stomach interrupted by periods of relief.…”

“…Although minimally invasive techniques have become the gold standard procedure for surgical treatment of achalasia, these techniques require experience. Moreover, Lopes et al [13] reported that either approach (laparotomy or laparoscopy) can be chosen, depending on the surgeon's experiences due to the fact that in achieving the final results (relief of dysphagia) are similar. We have chosen laparotomy for myotomy.…”

“…The following additional hypotheses were considered: a) the wall of the esophagus is assumed to be uniform along the length; B) the calculated masses are considered uniform along the length of the esophagus -whether or not chagasic; C) the movement analyzed is translational in x towards the esophagus -with no deflections or vibrations; D) the influence of surrounding organs is neglected. In order to obtain the mathematical model, Bond Graph and Movements Equations 12,14 have been adopted in studies carried out by the research group.…”

“…These two quantities can be defined as the main characteristics of the system and can also be measured in real time. Other features can also be analyzed and included as other variables in the model 12 . There are two types of systems modelling: "input-output and state-space representation" 13 .…”
