Introduction and objectives: Bilateral inguinal hernioplasty by endoscopic totally extraperitoneal approach (TEP) seems to increase the probability of complications and early postoperative pain compared to unilateral endoscopic hernioplasty. In this work we also try to determine if bilaterality increases the risk of conversion and recurrence during the learning curve. Methods: Between January 2017 and February 2020, 140 patients underwent TEP surgery by 2 surgeons in a single Center, establishing 2 groups: learning curve (LC) and mastery of the technique (MT). Conversion, intraoperative and postoperative complications, chronic pain, and recurrence were retrospectively analyzed. Logistic regression was performed to assess the effect of bilaterality on the results obtained. Results: 211 procedures were performed (CA: 80; SD: 131). The mean follow-up was 26.7 months (11-70, SD 1.9). The LC group presented an increase in conversion (5 % vs 3.05 %, p = 0.41), postoperative complications (16.2 % vs 10.7 %, p = 0.11) and recurrence (12.8 % vs 0 %, p < 0.001) compared to the MT group. In the LC group, bilaterality associated a non-significant increase in conversion (9.7 % vs 0 %, p = 0.94), complications (29 % vs 25 %, p = 0.76) and recurrence (19.3 % vs 18.7 %, p = 0.96). All the cases of conversion and recurrence took place in the second operated hernia. Conclusions: During the learning curve, bilateral inguinal hernioplasty by TEP increases the risk of conversion and recurrence of the hernia operated on second, and it is advisable not to include bilateral hernias in the initial training period. Studies with a larger number of cases could reach statistical significance. [ABSTRACT FROM AUTHOR]

Introduction: Spiegel-Casseri’s hernia (HSC) is an infrequent entity that represents about 2 % of abdominal wall herniary defects, but frequency could be increased due to its subdiagnosis. The diagnosis of HSC is usually diffi cult and unsuspected and it presents high risk of jamming and strangulation so its surgical management is imperative. A TC is essential for diagnosis. Case report: Male, with pathological antecedents of myasthenia gravis, who consults about bilateral inguinal hernia and left Spiegel-Casseri’s hernia. Due to his clinical history, an open preperitoneal surgical approach with Lichtenstein plastic to repair all the three defects is done. During the postoperative, he had a bruise on the dropped hernial sac, treated with conservative measures and control and didn’t require drainage. Discussion: Most series of notifi ed cases of HSC in the literature show variable incidence of attendant abdominal wall’s defects. In this case, myasthenia gravis, a chronic and weakening disease, prompted three associated parietal defects and limited anesthesiologist options and surgical approaches. HSC is an unusual entity and its association with others hernias even more, but it exists and must be taken into account to achieve an optimal treatment for the patient. [ABSTRACT FROM AUTHOR]

Introduction: Despite the important advances made in recent decades in the prevention of adverse events, foreign body abandonments continue to occur in the surgical fi eld (“never events”). Although the retained objects can occur asymptomatically, the potential complications are numerous, requiring in most cases a reoperation for their removal. Case report: We present the exceptional case of a patient who had to be reoperated to remove a surgical drain migrated to an inguinal hernia sac after accidental and inadverted rupture during its removal in the postoperative period of a previous surgery. Discussion: Most of the safety measures and prevention of these adverse events try to guarantee a correct count of surgical material during surgery. Correct actions must also be ensured in the removal of surgical drains to avoid this type of complications. [ABSTRACT FROM AUTHOR]
