Introduction: Trans-abdominal pre-peritoneal (TAPP) repair is one of the standard techniques for laparoscopic repair of groin hernias. Literature has shown that both total extraperitoneal (TEP) and TAPP are equally effective with similar outcomes but TAPP has an advantage over TEP as there is more working space, and it provides access to the opposite side for repair of occult hernias. We reviewed our experience of TAPP repair in complicated groin hernias and compared the outcomes with uncomplicated groin hernia.
Methods: Patients undergoing TAPP repair from January 2004 to December 2019 were analyzed, and divided into two groups-I uncomplicated and II complicated groin hernia.
Results: TAPP repair was performed in 820 patients, of which 70.3% had uncomplicated and 29.7% patients had complicated hernias. Occult hernia was detected in 61 patients. The intra-operative complications (16.8% vs 1.3%) and conversions (2.4%) were higher in complicated hernias. Laparoscopic assisted repair was used in 16.8% patients with complicated hernias. The incidence of post-operative complications (62.1% vs 17.3%; P value <.01) were significantly higher in complicated groin hernia patients. The median follow-up was 15 months; only three patients in the uncomplicated hernia group developed recurrence, and chronic groin pain was higher in the complicated hernia repair patients (P > .05) at 6 months.
Conclusion: Although operative time, incidence of intra-operative and post-operative complications (albeit minor in nature), and conversions to open are higher after TAPP repair for complicated groin hernias, the short-term outcomes (hematoma, mesh infection) as well as long-term outcomes (chronic groin pain, port site hernia and recurrence) are not different when compared with uncomplicated hernias. TAPP repair can be used in both complicated and uncomplicated groin hernias with similar short-term and long-term outcomes, albeit with a slightly higher incidence of minor complications in complicated hernias. This can be taken into consideration while operating on patients with complicated hernias and taking informed consent.

Background: The impact of completely reducing or transecting a hernia sac on seroma formation in laparoscopic surgery for lateral inguinal hernias remains debated. To date, no studies have compared the incidence of seroma in hernia sacs left untouched versus other surgical approaches. Abandoning the hernia sac involves avoiding manipulation of the inguinal canal, unlike the manipulation required for transection or reduction of the hernia sac.

An obturator hernia (OH) is a rare type of hernia that accounts for a very small proportion of all hernias and cases of small bowel obstruction. This condition predominantly affects older, underweight individuals, with the vast majority of patients being women. Laparotomy with simple suture closure of the defect is commonly used as surgical treatment for OH.

Purpose: In laparoscopic inguinal hernia surgery, proper recognition of loose connective tissue, nerves, vas deferens, and microvessels is important to prevent postoperative complications, such as recurrence, pain, sexual dysfunction, and bleeding. EUREKA (Anaut Inc., Tokyo, Japan) is a system that uses artificial intelligence (AI) for anatomical recognition.

Patients And Methods: Materials and Methods: The study included 76 patients (average age 61,4±15,3 years; 69 [91 %] males, 7 [9 %] females) with primary uncomplicated unilateral inguinal hernias who underwent TAPP. Patients were divided into two groups: group 1 - 52 patients in whom the AbsorbaTack fixation device was used to secure the mesh; group 2 - 24 patients in whom the LiquiBand FIX8 cyanoacrylate adhesive was used.
Background: Inguinal hernias are encountered commonly, but there is a lack of uniformity and standardization in repair techniques. There are a variety of repair methods, from open methods to laparoscopic approaches. The available laparoscopic techniques that exist for inguinal hernia repair are transabdominal preperitoneal (TAPP) repair and totally extraperitoneal (TEP) repair.
