UNASSIGNED: Amyand\'s hernia is a rare type of inguinal hernia which contains vermiform appendix in the inguinal sac, seldom complicated by acute appendicitis. It is usually repaired by open inguinal approach, but laparoscopic technique has been increasingly described in literature; nevertheless, standard of care is far from being defined. Here we report the case of Amyand\'s hernia complicated by acute appendicitis and simultaneous symptomatic left inguinal hernia, both repaired by laparoscopic technique.
METHODS: A 85-years-old man presented with acute appendicitis in Amyand\'s hernia and simultaneous incarcerated left inguinal hernia.
UNASSIGNED: After complete preoperative work-up, the patient underwent laparoscopic appendectomy and laparoscopic bilateral hernia repair with mesh.
CONCLUSIONS: Laparoscopic approach may be safe and feasible for Amyand\'s hernia treatment in emergency setting when performed by expert hands, with minimized risk of surgical site infection (SSI), quick recovery and reduced hospital stay. Laparoscopic hernia repair with mesh can be a reasonable approach in selected cases of bilateral or recurrent hernia, and concomitant intrabdominal inflammation, especially when contamination is scarse and limited to a restricted area.

BACKGROUND: Inguinal herniation of the urinary bladder is uncommon and those descending into the scrotum are even rarer. Although open anterior repair has been used for inguinal bladder hernia, the efficacy of laparoscopic herniorrhaphy has been reported in recent years.
METHODS: A 63-year-old man presented with an irreducible right groin and scrotal bulge associated with voiding difficulty. Abdominal ultrasonography showed a dislocation of the urinary bladder descending into the right scrotum. Abdominal CT imaging revealed that a part of the bladder and small intestine was herniating into the scrotum through the internal inguinal ring and running laterally to the inferior epigastric artery. Under the diagnosis of indirect inguinal bladder hernia, the patient underwent trans-abdominal preperitoneal hernia repair (TAPP). The bladder herniated into the scrotum through the internal inguinal ring was replaced to the original position. Then the myopectineal orifice was exposed and covered with polypropylene mesh, where a horizontal peritoneal incision 4 cm above the hernia orifice, i.e., the high peritoneal incision approach (HPIA), allowed an easy peeling of the peritoneum and hernia sac. The patient\'s postoperative course was uneventful and the voiding difficulty resolved. The patient continued to do well without recurrence at 20 months after surgery.
CONCLUSIONS: Preoperative evaluation with abdominal ultrasonography and CT scan allowed a precise diagnosis of a groin hernia with voiding difficulty. TAPP with HPIA was useful in the treatment of inguinal bladder hernia because this technique facilitated a quick confirmation of the hernia contents, secure dissection of the whole protruded bladder, and adequate replacement of the bladder to the original position without any injury.

Inguinal hernias, although a common occurrence, pose a significant threat to the surgical community on account of their complexity and socioeconomic consequences. Bilateral inguinal hernias, which are a rare subtype of inguinal hernias, in particular, are problematic since there are no existing definitive international guidelines for their repair. It is estimated that between 8% and 30% of inguinal hernia patients have bilateral hernias, but there is still no clarity as to whether a bilateral hernia represents a special type of inguinal hernia or two different hernias in one patient. The transabdominal pre-peritoneal repair (TAPP), totally extra-peritoneal repair (TEP), and Lichtenstein repair techniques are commonly employed depending on the resources and surgical expertise available, but there is a need to conduct large-scale, prospective, randomized-controlled trials to guide the formation of evidence-based guidelines that could be followed globally. Herein, we present the first known case of a bilateral inguinal hernia in a female pediatric patient repaired by the laparoscopic TAPP technique from Pakistan.

An obturator hernia is a rare pelvic hernia with high mortality. Early diagnosis and treatment are essential to reduce postoperative complications. The treatment of choice for obturator hernias is surgery. In an emergency, laparotomy to resolve herniated viscera and complications is often the choice. However, some researchers have shown the feasibility of laparoscopy. The laparoscopic approach has several benefits over the open approach, including reduced postoperative pain, early mobilization, shorter length of stay, and lower postoperative morbidity rates. We report the case of an 81-year-old woman with a right-side obstructed obturator hernia. The patient was hospitalized with an acute onset of inner thigh pain and bowel obstruction. The obturator hernia was diagnosed preoperatively by an abdominopelvic CT scan with the image of protrusion of an ileal loop in the right obturator foramen. The patient was treated by an emergency laparoscopy. The right obturator hernia and a concurrent right femoral hernia were confirmed during the operation. The hernia defect was repaired with a mesh large enough to cover all hernia foramen. The patient recovered without any complications. Emergency laparoscopic repair for obstructed obturator hernia was safe and effective.

Outdoor PM2.5 was sampled in Pretoria, 18 April 2017 to 28 February 2020. A case-crossover epidemiology study was associated for increased PM2.5 and trace elements with increased hospital admissions for respiratory disorders (J00-J99). The results included a significant increase in hospital admissions, with total PM2.5 of 2.7% (95% CI: 0.6, 4.9) per 10 µg·m-3 increase. For the trace elements, Ca of 4.0% (95% CI: 1.4%-6.8%), Cl of 0.7% (95% CI: 0.0%-1.4%), Fe of 3.3% (95% CI: 0.5%-6.1%), K of 1.8% (95% CI: 0.2-3.5) and Si of 1.3% (95% CI: 0.1%-2.5%). When controlling for PM2.5, only Ca of 3.2% (95% CI: 0.3, 6.1) and within the 0-14 age group by 5.2% (95% CI: 1.5, 9.1). Controlling for a co-pollutant that is highly correlated with PM2.5 does reduce overestimation, but further studies should include deposition rates and parallel sampling analysis.

UNASSIGNED: And importance: The most common postoperative complications after inguinal hernia repair are hernia recurrence, hematoma, seroma, wound infection, chronic pain, numbness and swelling. The aim of this case report is to present a rare complication of inguinal hernia repair, a large scrotal abscess that was caused by an inoculated scrotal hematoma 3 months after Transabdominal Preperitoneal bilateral inguinal hernia repair.
UNASSIGNED: An 84-year-old patient presented to the emergency department complaining about fever, pain and progressive swelling of the left hemiscrotum. He had undergone a Transabdominal Preperitoneal bilateral inguinal hernia repair 3 months earlier and a scrotal paracentesis 17 days earlier due to a scrotal hematoma. The pelvic CT scan was indicative of a large abscess in the left hemiscrotum compressing the ipsilateral testicle. Surgical exploration of the inguinal area was performed and considering the patient\'s advanced age the abscess was excised \"en bloc\" with the ischemic ipsilateral testicle. The patient had an uneventful recovery and was discharged home on the third postoperative day.
UNASSIGNED: Scrotal abscess, although rare, should be considered in the differential diagnosis of scrotal pain after inguinal hernioplasty. Scrotal drainage is sometimes used in order to relive the patient\'s discomfort caused by a swollen scrotum, but if not performed properly it can lead to serious infections. Postoperatively, a suction drain or elevation and compression of the scrotum may prevent scrotal complications.
UNASSIGNED: Scrotal abscess is a rare complication of inguinal hernioplasty. Scrotal care pathways establishment after inguinal hernia repair could help reduce and manage complications.

An 80-year-old woman presented to our emergency department with vomiting which had begun half a day prior to presentation. She had undergone open mesh plug repair for a right obturator hernia 1 year prior to presentation. Computed tomography detected recurrence of the right obturator hernia. Since intestinal viability was maintained, manual reduction of the incarcerated intestine was performed. The patient was admitted to our department to monitor delayed intestinal perforation. Laparoscopic transabdominal preperitoneal repair for obturator hernia was performed 5 days after admission. A self-fixating mesh was placed over the obturator hernia defect and femoral ring without tacking. The patient was discharged on postoperative day 6 without postoperative complications. At the 4-month follow-up, no signs of hernia recurrence or neuropathy were observed. Laparoscopic transabdominal preperitoneal repair for recurrent obturator hernia status post-open mesh plug repair by using self-fixating mesh is a safe and suitable procedure.

UNASSIGNED: With the widespread use of laparoscopic inguinal hernia repair, it is known that some clinically evident inguinal hernias lack a peritoneal sac and are referred to as \"sacless hernias\".
METHODS: A 61-year-old man presented with a left inguinal bulge. On physical examination, the diagnosis of bilateral inguinal hernias was made, and laparoscopic transabdominal repair was performed. Intraoperatively, the left peritoneal hernia orifice was not identified from the peritoneal cavity and there was only a lipoma. Pressing the lipoma with forceps from inside the peritoneum confirmed the presence of a hernia. The preperitoneal space was opened and the hernia orifice revealed.
CONCLUSIONS: The terminology and definition of sacless hernias are poorly defined, even though this is not a rare condition. Consistent with Russell\'s dogma, there are arguments that any prolapse can only be called a hernia if there is an accompanying peritoneal sac. The proportion of patients with sacless hernias and pure cord lipomas are very similar and these conditions are often confused. Detailed and repeated physical examination may distinguish a sacless hernia from a pure lipoma. A watchful waiting strategy is useful and ensures safety.
CONCLUSIONS: Once the diagnosis of inguinal hernia is made on physical examination, open the preperitoneal cavity if a peritoneal hernia orifice was not identified during laparoscopy.

BACKGROUND: We investigated the effectiveness of a self-gripping mesh, which has microgrips attached to fibrous tissue, in laparoscopic transabdominal preperitoneal (TAPP) obturator hernia (OH) repair to minimize the risk of postoperative pain and obturator nerve injury.
METHODS: The patient was an 80-year-old woman who was transferred to our emergency department with abdominal pain in the right lower quadrant and low back pain that began half a day prior to presentation. Computed tomography (CT) detected right OH. Based on the results of the laboratory examination and dynamic CT, intestinal viability was maintained. Ultrasonography-assisted manual reduction of the incarcerated intestine was performed, followed by admission to our department to check for delayed perforation of the intestine. Laparoscopic TAPP OH repair was performed on day seven as an elective surgery. A self-gripping mesh was placed over the OH defect and the femoral ring without tacking. The patient was discharged on postoperative day four, without any complications.
CONCLUSIONS: Tacking of the mesh at the lateral and dorsal sides of the obturator canal is dangerous due to the presence of the obturator nerve and vessels. Self-gripping mesh use in laparoscopic TAPP OH repair is a rational decision in terms of avoiding tacking or suturing around the obturator canal while maintaining stable fixation of the mesh to prevent recurrence.
CONCLUSIONS: Laparoscopic TAPP OH repair with self-gripping mesh is a rational treatment option that reduces the risk of obturator nerve injury while maintaining the secure fixation of a mesh to prevent recurrence.
