Introduction: lung cancer, an almost exceptional disease in the 20th century, has become a major health problem worldwide. Objective: to clinically and epidemiologically characterize lung cancer in patients operated in the surgery service of the Abel Santamaría Cuadrado Hospital, in the period 2021-2022. Methods: an analytical, descriptive, retrospective and cross-sectional study was carried out in patients operated at the "Abel Santamaría" Hospital. The universe and the sample consisted of 18 electively operated patients. Theoretical, empirical and descriptive statistical methods were used. The variables analyzed were age, sex, form of presentation, relationship with smoking, risk factors, histological subtype and type of surgery. Results: male sex and age group between 44 and 72 years old predominated, being the most frequent form of presentation the alteration of respiratory function, some with exacerbation of old symptoms followed by the general syndrome, with predominance of workers in the agricultural and industrial sectors. Adenocarcinoma was identified as the most frequent histological type, followed by squamous cell carcinoma, for a predominance of stage IIb and IIa. Conclusions: A clinical epidemiological behavior with a predominance of male patients over 50 years of age was verified, it is noteworthy that the predominant form of presentation was respiratory alterations, and the low association existing between these at the primary care level and by the general population with said disease.

Introduction: obturator hernias suppose an infrequent entity, reported in very old, thin and multiparous women, its location is more frequent in the right side. The preoperative diagnosis is a challenge and its management is surgical. Case report: a 48-year-old male patient with a history of relative nature health was presented; he attended the emergency department with abdominal pain of colic-diffuse type, predominantly in the lower abdomen, accompanied by nausea. Physical examination revealed peritoneal signs in the left iliac fossa; simple abdominal radiography provided an image of the intestinal loop at the level of the obturator foramen. An exploratory laparotomy was performed through infraumbilical mean and pinching of the antimesenteric edge of the terminal ileum segment was found through the obturator foramen, with distention of thin loops above the impingement; it was reduced without complications. The viability of the affected intestine segment was tested without the need for resection and the wall was repaired by plicating the peritoneum with non-resorbable suture as a result the defect was corrected. Conclusions: obturator hernia is an infrequent entity and practically not reported in young men and on the left side. Its clinical picture is nonspecific and the diagnosis depends on the clinical suspicion, complementary findings or during laparotomy. The treatment is always surgical.
