Congenital Transmesenteric Hernia With Closed-Loop Small Bowel Obstruction and Intestinal Gangrene in an Adult.

Internal hernias (IHs) are defined as the protrusion of the intestine through an aperture in the peritoneal ligament, mesentery, or the omentum, without traversing the fascial planes and leading to encapsulation of the protruded intestine within another compartment of an otherwise intact abdominal cavity. Internal hernias can be acquired or congenital. Congenital internal hernias resulting in small bowel obstruction are extremely rare, even more so in adults, occurring usually due to embryological or developmental defects, often undiagnosed, and requiring a high index of clinical suspicion. We report a rare case of a 22-year-old young adult with transmesenteric hernia of distal ileum through a congenital distal ileal mesenteric defect resulting in closed-loop small bowel obstruction and distal ileal gangrene, managed with resection and end-ileostomy, followed by stoma reversal one month later. It requires a high index of suspicion and remains a surgical emergency due to its predilection for intestinal gangrene and small bowel obstruction, with a high mortality rate due to delayed presentation and diagnosis.

Amyand's Hernia: Incarcerated Appendicitis in a Recurrent Inguinal Hernia in an Adult.

Inguinal hernias are among the most common cases presented to a surgeon. In spite of extensive research and clinical experience over centuries, inguinal hernias still pose anatomical challenges for operating surgeons, especially with a propensity for recurrence. One such complicated entity is the Amyand's hernia - defined as an inguinal hernia contained within the hernial sac - the vermiform appendix - as the herniated content. It is a rare clinical presentation and carries with it certain complexities with regard to operative decisions and clinical management. We present a case of a 71-year-old male presenting with a recurrent inguinal hernia, with an incarcerated, inflamed appendix as the content; managed surgically with appendicectomy and herniorraphy, without the use of a prosthetic mesh.

Surgical Management of Congenital Pulmonary Airway Malformations (CPAM) in an Infant and a Toddler: Case Report Depicting Two Distinct Surgical Techniques With Successful Outcomes.

Congenital pulmonary airway malformations (CPAM) compose the major part of congenital lung malformations (CLM) and have traditionally been treated by pulmonary lobectomy. In terms of surgical strategy, lobectomy has conventionally been the preferred treatment for CPAM localized to a single lobe. More recently, alternative approaches including lung-sparing resections (LSR), such as wedge or non-anatomic resections and segmentectomy, have been suggested. In asymptomatic CPAM early surgical resection is often shown to reduce infection and malignancy development. We describe two patients who were diagnosed with CPAM when being evaluated for respiratory tract infection. Patient 1 (P1) was a two-month-old infant weighing 4 kg with glucose-6-phosphate dehydrogenase (G6PD) deficiency and Patient 2 (P2) was a toddler aged one year, nine months weighing 9 kg. P1 underwent LSR for the CPAM diagnosed in the left upper lobe of the lung with conventional mechanical ventilation whilst right upper lobectomy was performed in P2 using one/single lung ventilation. In both cases, LSR and right upper lobectomy led to an uneventful postoperative recovery with no complications reported.
