To review the clinical presentation, outcome and causes of acute appendicitis presenting within a groin hernia. A comprehensive review of the past 70 years of English language surgical literature was conducted pertaining to acute appendicitis presenting within an inguinal or femoral hernia. Thirty-four reports describing 45 patients were reviewed to determine age, position, gender, pathologic stage at presentation, causal suppositions, and clinical outcomes. Hernial appendicitis presented as an inguinal abscess or a tender inguinal mass, often in the femoral position, and most commonly at the extremes of age. It was almost never recognized preoperatively, and, because of the sequestered nature of the inflammatory process, presented with few classic systemic signs or symptoms suggestive of acute appendicitis. Advanced pathologic stage and death correlated with the patient's age, delay in presentation, and delay in recognition. Evaluation of an inguinal abscess or a nonreducible tender groin hernia presenting in a patient at the extremes of age, should include computed tomography to rule out an occult acute appendicitis within the hernia, as systemic signs and symptoms of appendicitis are rarely evident. The condition appears to be caused by inflammatory adhesions caused by appendicitis occurring within an enlarged hernial orifice rather than appendicitis caused by external compression of the appendix base. Early recognition of this unique presentation of appendicitis allows trans-hernial appendectomy and immediate herniorraphy. Delayed diagnosis requires drainage of abscess with appendectomy and interval hernia repair.

A totally extraperitoneal approach to the identification, mobilization, and repair of lumbar hernia can be successfully accomplished using established laparoendoscopic surgical techniques.

AIM:To determine patient and process of care factors associated with performance of timely laparoscopic cholecystectomy for acute cholecystitis. METHODS:A retrospective medical record review of 88 consecutive patients with acute cholecystitis was conducted. Data collected included demographic data, co-morbidities, symptoms and physical findings at presentation, laboratory and radiological investigations, length of stay, complications, and admission service ( m e d i c a l o r s u r g i c a l ) . Pa t i e n t s n o t u n d e r g o i n g cholecystectomy during this hospitalization were excluded from analysis. Hierarchical generalized linear models were constructed to assess the association of pre-operative diagnostic procedures, presenting signs, and admitting service with time to surgery. RESULTS:Seventy cases met inclusion and exclusion criteria, among which 12 were admitted to the medical service and 58 to the surgical service. Mean ± SD time to surgery was 39.3 ± 43 h, with 87% of operations performed within 72 h of hospital arrival. In the adjusted models, longer time to surgery was associated with number of diagnostic studies and endoscopic retrograde cholangio-pancreatography (ERCP, P = 0.01) as well with admission to medical service without adjustment for ERCP (P < 0.05). Patients undergoing both magnetic resonance cholangiopancreatography (MRCP) and computed tomography (CT) scans experienced the longest waits for surgery. Patients admitted to the surgical versus medical service underwent surgery earlier (30.4 ± 34.9 vs 82.7 ± 55.1 h, P < 0.01), had less postoperative complications (12% vs 58%, P < 0.01), and shorter length of stay (4.3 ± 3.4 vs 8.1 ± 5.2 d, P < 0.01). CONCLUSION:Admission to the medical service and performance of numerous diagnostic procedures, ERCP, or MRCP combined with CT scan were associated with longer time to surgery. Expeditious performance of ERCP and MRCP and admission of medically stable patients with suspected cholecystitis to the surgical service to speed up time to surgery should be considered.

The semilateral decubitus position affords excellent access to the lesser sac, allowing excision of SAA with good visualization of the splenic artery and splenic hilar vessels should splenic hypoperfusion demand splenic resection. Excision of SAA is preferred to ligation except when dense adhesions or intrapancreatic arterial course preclude safe dissection. Pseudoaneurysms from trauma or pancreatitis are likely best treated with intraarterial embolization but significant complications should be expected in this high-risk subset of patients.

A comprehensive review of intraluminal duodenal diverticulum (IDD) is presented, along with a report of a completely laparoscopic excision of this duodenal abnormality as well as a report of magnetic resonance cholangiopancreatography demonstrating the classic fluoroscopic "wind sock sign" pathognomonic appearance of IDD. IDD may easily be missed unless one specifically considers this entity in patients presenting with symptoms of foregut disease. Patients with IDD typically present in the fourth decade of life with duration of symptoms less than 5 years that typically include pain, nausea and vomiting, pancreatitis, and gastrointestinal bleeding. Diagnosis usually requires imaging studies and upper gastrointestinal endoscopy. Laparoscopic excision is recommended because of superior visualization of significant intestinal anatomic abnormalities, the need for accurate ampullary localization, and the ability to facilitate complete diverticular excision while maintaining biliary and pancreatic ductal integrity. Review of surgical literature suggests that IDD results from congenital duodenal developmental abnormalities matured by long-term duodenal peristalsis.
