Emergency repair of Morgagni hernia with partial gastric volvulus: our approach.

Morgagni hernias are a rare form of congenital diaphragmatic hernias, thus there is paucity in literature about the diagnosis and management of the condition. We report an 83-year-old woman who presented with vomiting and a metabolic acidosis with a previous computed tomography diagnosis of Bochdalek's hernia. Diagnostic laparoscopy revealed a Morgagni hernia containing transverse colon, greater curvature of the stomach and a partial gastric volvulus. The hernia was reduced with the sac untouched, and the defect was closed with a composite mesh using tac fixation. The operation was done successfully in 45 minutes with no complications.

Computed tomography in the investigation and management of obturator hernia.

INTRODUCTION: Obturator hernias are a rare groin hernia. They are most commonly found incidentally during laparoscopic inguinal hernia repair. We investigated our experience with obturator hernias in the elective and emergency setting. METHODS: Cases of obturator hernia were identified from a hospital database and reviewed retrospectively over the last 10 years. There were no exclusions. There were a number of surgeons involved with an interest in groin hernia surgery. RESULTS: Twenty-one patients were included. The mean age was 66 years old. Eleven were male. There were four emergency presentations. One emergency case presented with small bowel obstruction, while the other three cases presented with groin pain. Two patients had a preoperative computed tomography, which showed an obturator hernia confirmed at surgery. The patient with small bowel obstruction had an open bowel resection alone with no hernia repair. They were discharged with no complications or recurrence on follow-up. The other three cases had a mesh repair (one laparoscopic, one laparotomy, one pre-peritoneal). One patient who underwent a laparotomy died of a post-operative pneumonia. The others were discharged uneventfully. In the elective group of 17 patients, 8 patients were taken for an elective laparoscopic inguinal hernia repair but found to actually have an obturator hernia alone. An obturator hernia was found incidentally with an inguinal hernia in three patients. Five patients were expected to have an obturator hernia on clinical examination alone. At surgery, an obturator hernia was found in three cases. In the other two cases, no hernia was found. One patient had a pre-operative computed tomography, which showed an obturator hernia confirmed at surgery. CONCLUSIONS: Computed tomography would be recommended in cases of diagnostic uncertainty. It may avoid unnecessary surgery in the elective setting and allow a focused procedure in the emergency setting. Laparoscopic repair is feasible in the emergency and elective setting with excellent results.

Trans-fascial closure in laparoscopic ventral hernia repair.

BACKGROUND: Laparoscopic incisional hernia repair has become widely accepted in the management of incisional hernias. There has been recent interest in combining fascial closure along with mesh placement to improve outcomes. We report our experience with this technique. METHODS: Cases were evaluated retrospectively from 2012 to 2015. There were no exclusions. Cases were included which involved laparoscopic ventral hernia repair with fascial closure and mesh placement. Fascial closure was performed using non-absorbable sutures passed with a suture passage device percutaneously. A 5-cm overlap was performed using intra-peritoneal mesh. Fixation was performed using absorbable tacks in a double crown technique. RESULTS: One hundred and twelve cases were included. The mean age was 57 years old (range 33-81 years). Fifty-nine were females and 53 were males. The median post-operative stay for the non-fascial closure group was 0 days (range 0-12 days). The median post-operative stay for the fascial closure group was 0 days (range 0-12 days). All cases were followed up clinically at 6 weeks. In the non-fascial closure group, five patients developed a seroma (12 %). One patient developed a wound infection (3 %). Six patients presented with a recurrence over the study period (15 %). In the fascial closure group, four patients had a seroma, which was managed conservatively (5 %). One patient developed a wound infection (1 %). Five patients developed a recurrence over the study period (7 %). CONCLUSION: We have shown comparable rates for seroma and recurrence to other series. Laparoscopic incisional hernia repair with defect closure is feasible and reduces seroma rate and recurrence.

Use of the Ambu® aScope 2TM in laparoscopic common bile duct exploration.

BACKGROUND: We have recently begun to use a sterile disposable endoscope to perform laparoscopic common bile duct exploration. We evaluated our practice in a large district general hospital and reported the early feasibility of this equipment in performing bile duct exploration. METHODS: We began to use the Ambu® aScope 2TM from June 2015 in our institution. Any case eligible for a laparoscopic common bile duct exploration was included. Our study period is from June 2015 to November 2015. Data were collected and analysed retrospectively. RESULTS: Thirteen patients were included. Nine were female and five were male. The mean age was 59 years old (range 28 to 82 years). Seven were performed as an emergency and six were performed for elective cases. All patients had common bile duct stones with no history of previous cholecystectomy. The Ambu® aScope 2TM was used in 11 cases, and a standard choledocoscope was used in two cases due to lack of availability of the Ambu® aScope 2TM. There was one conversion due to an impacted bile duct stone and technical difficulty intra-operatively. Five cases were performed as a transcystic exploration with 1 case being converted to a choledocotomy due to inability to pass the cystic duct using the Ambu® aScope 2TM. The mean operating time was 158 min (range 85-255 min). The mean operative time using the reusable endoscope was 130 min. The mean postoperative stay was 3 days (range 0-8 days). CONCLUSIONS: The use of the Ambu® aScope 2TM is safe and feasible in laparoscopic common bile duct exploration. It confers significant financial benefits and offers an economical alternative to expensive reusable endoscopes.

Laparoscopic common bile duct exploration: 15-year experience in a district general hospital.

INTRODUCTION: The treatment of common bile duct (CBD) stones remains controversial with debate between endoscopic cholangiopancreatography (ERCP) and CBD exploration. A recent meta-analysis has shown no significant difference between these approaches; however, there is a trend in the literature to favour a single-stage procedure in the form of laparoscopic CBD exploration. We report our experience over a 15-year period. METHODS: All cases of CBD exploration were identified from 2000 to 2015 and analysed retrospectively from a large NHS Foundation Trust in Northumbria. There were no exclusions. The mean clinical follow-up was 6 months (range 3-36 months). RESULTS: A total of 296 patients were included who underwent laparoscopic CBD exploration: 203 were female and 93 were male. The mean age was 60 years (range 16-84 years). A total of 231 procedures were performed electively and 65 as an emergency. Ten procedures were successfully performed as day cases. Eleven procedures were converted to an open procedure due to adhesions or a difficult dissection (4 %). Sixty-three procedures were performed with a transcystic approach with a mean post-op stay of 2 days (range 0-7). A total of 233 procedures were performed with a choledocotomy with a mean post-op stay of 6 days (range 3-14 days). Stone clearance was successful in 255 patients (86 %). Three patients died over the study period. Two were for medical complications and one for abdominal sepsis. Three patients returned to theatre for early post-operative bleeding (1 %). Sixteen patients had persistent bile leaks following a choledocotomy (6.8 %). No patients had a bile leak following transcystic exploration. Fourteen patients were followed up following failed stone removal. Nine had a successful ERCP, three had no stone seen on MRCP, and one patient required re-operation following a failed ERCP. CONCLUSIONS: Laparoscopic bile duct exploration can be performed successfully in both the emergency and elective settings. Day-case surgery is feasible in selected patients. A transcystic approach should be favoured where possible.

Safe removal of long-term venous catheters in the neck.

AIMS: Tunnelled venous catheters are a well-established method of long-term venous access for total parental nutrition, chemotherapy and antimicrobial treatment. Removal of these catheters is a simple procedure; however, there are some significant risks. METHODS: We report a case in which a serious complication occurred. A simple technique for the safe removal of long-term venous catheters is described. CONCLUSION: A direct surgical removal is now generally favoured for safe line removal. However, this still carries the same complications and care must be taken in the technique.

Meta-analysis of sonography in the diagnosis of inguinal hernias.

Groin hernias are common conditions, and there is a need for accurate imaging when the clinical diagnosis is not clear. A meta-analysis was undertaken to investigate the diagnostic accuracy of sonography in the diagnosis of inguinal hernias. After review of literature searches, 9 original articles were included. Data were pooled and statistically analyzed. In the studies included, sensitivity ranged from 92.7% to 100%; specificity ranged from 22.2% to 100%; the positive predictive value ranged from 83.3 to 100%; and the negative predictive value ranged from 40 to 100%. Sonography has overall sensitivity of 96.6 %, specificity of 84.8%, and a positive predictive value of 92.6%. In cases of diagnostic uncertainty, sonography offers value as an initial imaging modality. It has advantages over other radiologic methods, as it is inexpensive and has minimal complications. When the clinical diagnosis of an inguinal hernia is uncertain, sonographic findings should be interpreted in conjunction with clinical judgment, as its diagnostic accuracy is reduced in the absence of any clinically palpable hernia.

A systematic review and meta-analysis of the role of radiology in the diagnosis of occult inguinal hernia.

BACKGROUND: Inguinal hernias are a common cause of groin pain. Most hernias are detectable by clinical examination and many patients proceed to hernia repair on the basis of history and examination findings alone. However, a significant proportion of patients with symptoms suggestive of groin hernia are found to have a normal clinical examination. Several radiological techniques have been developed to solve the dilemma posed by occult inguinal hernias. No systematic review or meta-analysis has addressed this common clinical problem. METHODS: A systematic review and meta-analysis were undertaken of relevant articles in Medline, Embase, and the Cochrane database. Studies were assessed using the QUADAS tool. Statistical analysis was undertaken. RESULTS: We have shown in this meta-analysis that ultrasound has a sensitivity of 86% and a specificity of 77% in occult inguinal hernias. Computed tomography has a sensitivity of 80% and a specificity of 65%. Herniography has a sensitivity of 91% and a specificity of 83%. CONCLUSIONS: Based on this systematic review, herniography should be considered as the initial investigation for occult inguinal hernia where available. In centers where this is not available, ultrasound of the groin should be used with good clinical judgment. When there is still diagnostic uncertainty, further investigation with magnetic resonance imaging should be considered to exclude alternative pathology.

Pneumatosis Intestinalis of the Small Bowel; Radiological and Intra-operative findings.

Pneumatosis Intestinalis is defined as the infiltration of gas into the bowel wall. It is a radiological and intra-operative finding of varying aetiology which varies from benign to life threatening conditions. We describe here a case of a 67 year old woman who presented with diffuse abdominal pain and was found to have Pneumatosis Intestinalis.
