Boerhaave syndrome (BS) and subsequent septic mediastinitis represent a complex cascade of events from esophageal perforation to septic shock. The pathophysiology involves chemical injury, polymicrobial contamination, cytokine storm, endothelial dysfunction, coagulation disorders, and ultimately multiple organ failure. Understanding these mechanisms is crucial for proper therapeutic management that can interrupt this lethal sequence. Due to the complexity of this condition, it is almost impossible to develop a feasible treatment protocol for every situation. The article, through a literature review, evaluates the pathophysiological mechanisms, the consequences of spontaneous esophageal rupture, as well as the therapeutic techniques available for these situations. These elements are the basis of the management of spontaneous esophageal rupture, which involves adapting and customizing the treatment for each patient.

Cases of digestive cancers diagnosed during pregnancy are rare. The increasing prevalence of pregnancy in women aged 30–39 years (and not exceptionally 40–49 years) could explain the frequent co-occurrence of cancers and pregnancy. The diagnosis of digestive cancers in pregnancy is difficult due to the overlap between neoplasm symptomatology and the clinical picture of pregnancy. A paraclinical evaluation may also be difficult depending on the trimester of the pregnancy. Diagnosis is also delayed by practitioners’ hesitation to use invasive investigations (imaging, endoscopy, etc.) due to fetal safety concerns. Therefore, digestive cancers are often diagnosed during pregnancy in advanced stages, where complications such as occlusions, perforations, and cachexia have already arisen. In this review, we highlight the epidemiology, clinical aspects, paraclinical evaluation, and particularities of the diagnosis and treatment of gastric cancer during pregnancy.

A rare entity of non-hiatal type transdiaphragmatic hernias, which must be clearly differentiated from paraoesophageal hernias, are the phrenic defects that bear the generic name of congenital hernias—Bochdalek hernia and Larey-Morgagni hernia, respectively. The etiological substrate is relatively simple: the presence of preformed anatomical openings, which either do or do not enable transit from the thoracic region to the abdominal region or, most often, vice versa, from the abdomen to the thorax, of various visceral elements (spleen, liver, stomach, colon, pancreas, etc.). Apart from the congenital origin, a somewhat rarer group is described, representing about 1–7% of the total: an acquired variant of the traumatic type, frequently through a contusive type mechanism, which produces diaphragmatic strains/ruptures. Apparently, the symptomatology is heterogeneous, being dependent on the location of the hernia, the dimensions of the defect, which abdominal viscera is involved through the hernial opening, its degree of migration, and whether there are volvulation/ischemia/obstruction phenomena. Often, its clinical appearance is modest, mainly incidental discoveries, the majority being digestive manifestations. Severe digestive complications such as strangulation, volvus, and perforation are rare and are accompanied by severe shock, suddenly appearing after several non-specific digestive prodromes. Diagnosis combines imaging evaluations (plain radiology, contrast, CT) with endoscopic ones. Surgical treatment is recommended regardless of the side on which the diaphragmatic defect is located or the secondary symptoms due to potential complications. The approach options are thoracic, abdominal or combined thoracoabdominal approach, and classic or minimally invasive. Most often, selection of the type of approach should be made taking into account two elements: the size of the defect, assessed by CT, and the presence of major complications. Any hiatal defect that is larger than 5 cm2 (the hiatal hernia surface (HSA)) has a formal recommendation of mesh reinforcement. The recurrence rate is not negligible, and statistical data show that the period of the first postoperative year is prime for recurrence, being directly proportional to the size of the defect. As a result, in patients who were required to use mesh, the recurrence rate is somewhere between 27 and 41% (!), while for cases with primary suture, i.e., with a modest diaphragmatic defect, this is approx. 4%.

Esophageal fistula remains one of the main postoperative complications, with the treatment often requiring the use of stents. This article reviews the updates on the use of endoscopic stents for the treatment of postoperative esophageal leakage in terms of indications, types of stents used, efficiency, specific complications and perspectives. Materials and Methods: We searched the PubMed and MEDLINE databases for the keywords postoperative esophageal anastomotic leak and postoperative esophageal anastomotic leak stent, and retrieved relevant papers published until December 2022. Results: The endoscopic discovery of the fistula is usually followed by the insertion of a fully covered esophageal stent. It has an efficiency of more than 60% in closing the fistula, and the failure is related to the delayed application of the method, a situation more suitable for endo vac therapy. The most common complication is migration, but life-threatening complications have also been described. The combination of the advantages of endoscopic stents and vacuum therapy is probably found in the emerging VACstent procedure. Conclusions: Although the competing approaches give promising results, this method has a well-defined place in the treatment of esophageal fistulas, and it is probably necessary to refine the indications for each individual procedure.

Introduction: Idiopathic megacolon (IM) is a rare condition with a more or less known etiology, which involves management challenges, especially therapeutic, and both gastroenterology and surgery services. With insufficiently drawn out protocols, but with occasionally formidable complications, the condition management can be difficult for any general surgery team, either as a failure of drug therapy (in the context of a known case, initially managed by a gastroenterologist) or as a surgical emergency (in which the diagnostic surprise leads additional difficulties to the tactical decision), when the speed imposed by the severity of the case can lead to inadequate strategies, with possibly critical consequences. Method: With such a motivation, and having available experience limited by the small number of cases (described by all medical teams concerned with this pathology), the revision of the literature with the update of management landmarks from the surgical perspective of the pathology appears as justified by this article. Results: If the diagnosis of megacolon is made relatively easily by imaging the colorectal dilation (which is associated with initial and/or consecutive clinical aspects), the establishing of the diagnosis of idiopathic megacolon is based in practice almost exclusively on a principle of exclusion, and after evaluating the absence of some known causes that can lead to the occurrence of these anatomic and clinical changes, mimetically, clinically, and paraclinically, with IM (intramural aganglionosis, distal obstructions, intoxications, etc.). If the etiopathogenic theories, based on an increase in the performance of the arsenal of investigations of the disease, have registered a continuous improvement and an increase of objectivity, unfortunately, the curative surgical treatment options still revolve around the same resection techniques. Moreover, the possibility of developing a form of etiopathogenic treatment seems as remote as ever.
