Rare presentation of De Garengeot hernia treated by transabdominal preperitoneal hernia repair: A case report

We present a rare case of De Garengeot hernia treated with simultaneous laparoscopic appendectomy and transabdominal preperitoneal hernia repair. Our patient was an 85-year-old man with a bulging mass in the right groin. De Garengeot hernia was observed on contrast-enhanced CT. Urgent laparoscopy showed the distal part of the appendix passing through a right-sided femoral hernia. Laparoscopic appendectomy was performed, followed by transabdominal preperitoneal repair of the femoral hernia. Pathological examination revealed ischemic necrosis of the appendix. The patient's postoperative recovery was uneventful.     

Development of a novel training system for laparoscopic inguinal hernia repair

Background: Laparoscopic inguinal hernia repair is considered technically difficult. Although a simulation-based curriculum has been developed to help trainees, access to simulation training outside North America is limited. This study aimed to develop an educational system for the transabdominal preperitoneal (TAPP) approach based on the TAPP checklist, an assessment tool we had developed and validated earlier.

Material and methods: Consensus within the TAPP education working group consisting of local TAPP experts, hernia experts and a surgical educator to develop educational tools and the educational system based on the TAPP checklist. The system was piloted in several institutes, and participants were surveyed on its efficacy.

Results: We systematically developed an educational video and training manual explaining each item of the TAPP checklist and conveying basic knowledge of the procedure. We integrated the training tool with evaluation and feedback to develop an educational system. In a pilot study, seven trainees at five hospitals were trained using this system and found it very useful for mastering the TAPP procedure.

Conclusions: We have developed a training system for TAPP procedure and successfully implemented it in several hospitals. Further research will focus on the educational value of this tool.     

Single‐incision totally extraperitoneal inguinal hernia repair is safe and feasible in elderly patients: A single‐center experience of 365 procedures

The aim of this study was to evaluate the feasibility and safety of SILS for totally extraperitoneal inguinal hernia repair in elderly patients. A retrospective analysis of 365 patients who underwent of SILS for totally extraperitoneal inguinal hernia repair from January 2012 to November 2015 at Osaka Police Hospital was performed, and the outcomes of patients aged <80 years and those aged ≥80 years were compared. There was a greater proportion of patients with an ASA score ≥3 among those ≥80 years than among those <80 years. The mean operative time for unilateral inguinal hernia was 94 min in patients <80 years and 98 min in patients ≥80 years. The mean operative time for bilateral inguinal hernia was 133 min in patients <80 years and 130 min in patients ≥80. Intraoperative bleeding was minimal in all patients. Conversion to a different operative procedure occurred in 3% (10/322) of patients <80 years and in 5% (2/43) of patients ≥80 years (P = 0.6). The mean postoperative hospital stay was 2.2 days for patients <80 years and 2.2 days for patients ≥80 years. The mean follow‐up period 21 ± 14 months (range, 3–50 months) for patients <80 years and 17 ± 14 months (range, 3–50 months) for patients ≥80 years (P = 0.3). Postoperative complications were seen in 12% (38/322) of patients <80 years and in 14% (6/43) of patients ≥80 years (P = 0.7). A seroma was seen in 9% (28/322) of patients <80 years and in 12% (5/43) of patients ≥80 years (P = 0.6). A wound infection occurred in 2% (8/322) of patients <80 years. These seromas and wound infections were managed conservatively. Pulmonary embolism was seen in one patient <80 years (0.3%). There was no mortality or recurrence in either group. SILS for totally extraperitoneal inguinal hernia repair has good cosmesis and can be performed in elderly patients with acceptable morbidity and mortality.     

Short‐term outcome of single‐incision laparoscopic totally extra‐peritoneal inguinal hernia repair

We performed single‐incision laparoscopic surgery for totally extra‐peritoneal (SILS‐TEP) repair using a lightweight mesh fixed by absorbable tacks and without balloon dilation. Thirty‐four patients (mean age, 66.5 years) underwent SILS‐TEP repair in our hospital between September 2011 and April 2012; 30 patients had unilateral hernia and 4 had bilateral hernias. Mean operative time was 85.6 min for unilateral hernia and 137.7 min for bilateral hernias. All patients underwent successful SILS‐TEP repair. Mean hospital stay was 3.4 days. Mean duration of follow‐up was 7.1 months. Four seromas were observed, but no recurrences or major complications occurred. SILS‐TEP is an economical and useful method for decreasing postoperative complications, such as neuralgia and recurrence, and it could be an attractive approach for inguinal hernia.     

Technical considerations for laparoscopic transabdominal preperitoneal repair of concurrent Spigelian-inguinal hernia complex: A case report and review of literature

Spigelian hernia with concurrent inguinal hernia is not uncommon. The hernia location makes conventional laparoscopic repair challenging and this is commonly repaired by the open method. We present the technical considerations and feasibility, as well as literature review, of such a hernia repaired via a minimally invasive fashion. We performed a laparoscopic transabdominal preperitoneal hernia repair for a 59-year-old woman who presented with symptomatic irreducible large Spigelian-inguinal complex hernia, with a hernia neck of 4 cm on computed tomography scan. The hernia contents were reduced transabdominally and subsequently, the preperitoneal space was created via a transabdominal preperitoneal method to allow for hernia defect closure and subsequent mesh placement. The patient was discharged on postoperative day 2 without complication. At 6 months follow-up, she had no complications or recurrence. With increased experience, the laparoscopic repair of complex Spigelian-inguinal concurrent hernias is safe and feasible.     

Single‐incision laparoscopic totally extraperitoneal obturator hernia repair in a patient on antiplatelet therapy: A case report

An 83‐year‐old woman who complained of right lower limb discomfort was diagnosed with a right obturator hernia by CT scan. On examination, she had a soft and flat abdomen without signs of peritoneal irritation. The Howship–Romberg sign was present. She had a history of vasospastic angina and paroxysmal supraventricular tachycardia, and took aspirin and dipyridamole until she was admitted to the hospital. Exploratory laparoscopy identified a spontaneously reduced small bowel from the right obturator canal, but there were no signs of ischemic and necrotic bowel. The patient underwent SILS for totally extraperitoneal obturator hernia repair without a dissection balloon. The patient recovered without perioperative complications such as hemorrhage and thrombotic episodes. She remains well, and CT scans showed no signs of obturator hernia recurrence at the 7‐month follow‐up.     

Single‐incision laparoscopic totally extraperitoneal repair for bilateral inguinal hernias after femoral‐femoral artery bypass in a patient on antiplatelet therapy: A case report

A 77‐year‐old man visited our hospital due to bilateral painful inguinal swellings. He had a history of femoral‐femoral artery bypass surgery for peripheral artery disease and took ethyl icosapentate. Additionally, he had a previous history of open left colectomy for descending colon cancer and had a median incision reaching the lower abdomen. With a diagnosis of bilateral direct inguinal hernias after femoral‐femoral artery bypass surgery, he underwent single‐incision laparoscopic surgery for totally extraperitoneal repair, continuing on ethyl icosapentate. During surgery, the preperitoneal space was safely and easily dissected, avoiding a subcutaneous vascular graft. No perioperative complications or hernia recurrence have been observed at 3 months follow‐up.     

Advantages of contrast‐enhanced ultrasonography over computed tomography for the detection of persistent type II endoleak after embolization: A case report

The aim of this case report is to describe the use of contrast‐enhanced ultrasonography in the detection of a type II endoleak after prior embolization with Onyx. A 74‐year‐old male patient with hypertension previously underwent endovascular repair of a 7.1‐cm infrarenal aortic aneurysm. CT angiography surveillance revealed a type II endoleak associated with aneurysm sac expansion. Selective transarterial embolization of the endoleak was performed, but it was not possible to detect the persistent endoleak using CT angiography because of image artifacts caused by Onyx. Contrast‐enhanced ultrasonography enabled us to detect the persistent endoleak in this patient. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44 :522–526, 2016
