950 Experience of Inguinal Mesh Hernioplasty Under Local Anaesthesia: A 3-Year Experience in A Teaching Hospital

Objective

To prove Inguinal mesh hernioplasty under L/A is safe and acceptable. Helps with post-operative pain and enables rapid recovery as a day case.

Method

All patients who underwent inguinal hernia repair under local anaesthesia were retrospectively analysed in our hospital between July 2014- July 2017. Clinical judgement was used for inclusion and exclusion parameters.

Results

From July 2014- July 2017, 260 patients were included in study who underwent Inguinal mesh hernioplasty under L/A. ASA grade for all patients ranged between I-III. The mean age was 37 (20-65). Intraoperatively (9.1) 3.5% patients had problems such as pain, hypotension or sweating. About (86.3%) 224 patients were discharged home the same day and remaining stayed overnight for less than 24 hours. Hematoma was seen in 5 (1.92%) patients, Urinary retention in 2 (0.7%) patients, Wound infection seen in 24(9.2%) patients, Readmission in 10 (3.8%) patients. Chronic groin pain was seen in 10 (3.9%) patients and no recurrence on 6 months follow up.

Conclusions

Our results showed that this procedure is feasible under L/A and can be performed safely. It showed satisfactory acceptance by the operating surgeon and patient, without significant perioperative issues. It is reliable and showed shorter hospital stay.

P9: MANAGEMENT OF ESOPHAGEAL FOOD BOLUS OBSTRUCTION AT A UNIVERSITY TEACHING HOSPITAL – A RETROSPECTIVE ANALYSIS

Introduction

Despite the fact that esophageal food bolus obstruction is a common surgical problem, there are no clear guidelines on its management. Medical treatment with Buscopan and Glucagon is mostly in-effective, requiring a therapeutic Oesophago-Gastro-Duodenoscopy (OGD).

Method

All consecutive cases of food bolus obstructions (FBO) presenting to the Emergency Department (ED) for 18 month period between 01/01/2018 and 30/06/2019 were retrospectively reviewed.

Result

A total of 30 patients were admitted with food bolus obstruction via ED (1.67 per month). Females (67%) constituted most of these patients. Average age was 55 with range of 19-83. 84% of patients presented with Dysphagia, while Odynophagia (10%) and chest pain (6%) were other presenting symptoms. Average duration of symptoms was 17 hours (Range 2 – 48 hours). 44% of patients had OGD done under sedation while others (56%) had under General Anaesthesia (GA). In 70% of cases, food bolus was pushed into stomach, while it was retrieved out in 20%. In 10%, it had already spontaneously passed in stomach on OGD. The etiology of FBO was inflammatory in 60% cases, while an esophageal stricture was seen in 10% only. In 30% cases no cause of FBO was identified. Post-OGD length of stay was on average 1.15 days (range 12 hours – 7 days). 2 patients had aspiration pneumonia prolonging their hospital stay, there was no esophageal perforation or mortality.

Conclusion

Esophageal food bolus obstruction is a common surgical problem, OGD under GA is a safe recommended procedure, which often picks up an underlying pathology.

Take-home message

Esophageal food bolus obstruction is a common surgical problem, OGD under GA is a safe recommended procedure, which often picks up an underlying pathology.

Risk factors for recurrent primary sclerosing cholangitis after liver transplantation

BACKGROUND & AIMS

The association between primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) is well recognised. However, the relationship between IBD and recurrent PSC (rPSC) is less well understood. We assessed the prevalence of rPSC and analysed the factors associated with rPSC post-liver transplantation and its influence on graft and patient survival.

METHODS

This is a UK multicentre observational cohort study across six of the seven national liver transplant units. All patients undergoing a first liver transplant for PSC between January 1 1990 and December 31 2010 were included. Prospectively collected liver transplant data was obtained from NHSBT and colitis data was retrospectively collected from individual units.

RESULTS

There were 679 (8.8%) first transplants for PSC. 347 patients (61.4%) had IBD, of which 306 (88.2%) had ulcerative colitis (UC). 81 (14.3%) patients developed rPSC and 37 (48.7%) of them developed graft failure from rPSC. Presence of UC post-liver transplant (HR=2.40, 95% CI 1.44-4.02) and younger age (HR=0.78, 95% CI 0.66-0.93) were the only factors significantly associated with rPSC. rPSC was associated with over a 4-fold increase in the risk of death (HR=4.71, 95% CI 3.39, 6.56) with 1, 5, and 10-year graft survival rates of 98%, 84%, and 56% respectively compared to 95%, 88%, and 72% in patients who did not develop rPSC.

CONCLUSION

The presence of UC post-liver transplant is associated with a significantly increased risk of rPSC. Furthermore, the presence of rPSC increases the rate of graft failure and death, with higher re-transplantation rates.

Spontaneous rupture of hepatocellular carcinoma: a Western experience

BACKGROUND

Spontaneous rupture of hepatocellular carcinoma (HCC) is a life-threatening presentation, with an incidence of <3% of HCC patients in Western countries. The reported overall mortality is < or =50% in Asian countries, where the incidence is 12% to 14%. The aim of this study was to report a single center's experience of patients with ruptured HCC during a 11-year period.

METHODS

A retrospective review was performed of all patients who presented with ruptured HCC between 1995 and 2005. Data on clinical features, treatment strategies, and survival outcomes were collected. Statistical methods included univariate analysis and Kaplan-Meier survival estimates with log-rank test.

RESULTS

A cohort of 21 patients (15 male and 6 female) was identified. Fourteen (66.6%) patients had histologic evidence of underlying cirrhosis, ad the median age at presentation was 68 years (interquartile range [IQR] 61 to 69). Ten of these patients (71.4%) were hemodynamically unstable at presentation. The mean tumor size was 8.5 cm (range 3 to 13), and there was multifocal disease in 6 (42.8%) patients. The etiology of cirrhosis was hepatitis B infection in 3, hepatitis C in 3, alcohol in 4, and cryptogenic in 4 patients. Initial bleeding control was attempted by transarterial embolization (TAE) in 7 (50%) and by emergency surgery in 7 patients (50%). Four of the operations were performed at referring hospitals, and 3 were performed at our institution. Two patients (14.2%) underwent palliative treatment only. Definitive treatment included resection at emergency surgery in 1, staged hepatectomy in 1, and transarterial chemoembolization in 2 patients. There were 7 patients who were noncirrhotic and had a median age of 51 years (IQR 42 to 60). Of these, 6 (87.5%) were hemodynamically unstable at presentation. Mean tumor size was 9 cm (range 6 to 18) and confined to right lobe in all patients. Primary hemostasis was successfully achieved by TAE in 2 and perihepatic packing in 1 patient. Definitive treatment was provided by emergency hepatectomy in 4 and staged hepatectomy in 3 patients. Patients with cirrhosis (n = 14) had a median survival rate of <30 days. Child-Pugh score at presentation (median 7, IQR 5 to 8) correlated strongly with overall survival (P <.0001). Median survival for noncirrhotic patients was 20 months (IQR 2 to 31). One patient without cirrhosis survived for 122 months without disease recurrence.

CONCLUSIONS

Spontaneous rupture of HCC is an uncommon presentation in Western countries. Primary hemostasis, followed by emergency or staged hepatic resection, is the treatment of choice. Median survival in patients initially treated with surgery was better than that observed in patients who underwent initial TAE, although this was not statistically significant. Patients who had no underlying liver disease had better prognosis than those who had cirrhosis.

Non-functioning well-differentiated neuroendocrine tumor of the extrahepatic bile duct: an unusual suspect?

BACKGROUND

Neuroendocrine tumors (NETs) arising in the biliary tree are extremely rare, and 37 cases were identified in the English literature.

METHODS

A well-differentiated NET was found arising from the junction of the cystic and common hepatic ducts, in a 51-year-old male presenting with pedal edema and weight loss with abnormal liver enzymes and a normal serum bilirubin level. No mass was seen on radiological imaging and biopsy of the liver was suggestive of an early cholangiopathy. A bile leak complicating the liver biopsy led to an ERCP that demonstrated a filling defect suggestive of a mass in the common bile duct (CBD).

RESULTS

He underwent a successful excision of the tumor with a Roux-en-Y hepaticojejunostomy. The diagnosis of NET was made on histological and immunohistochemical analysis of the resected specimen. He remains well and disease free 22 months after surgery.

CONCLUSIONS

Recognition of biliary NET continues to be a challenge and an increased awareness of these tumors in rare sites will result in optimal management of these tumors.

Auxiliary liver transplantation for propionic acidemia: a 10-year follow-up

Orthotopic liver transplantation (OLT) is an established treatment for patients with liver-based metabolic disorders that produce structural and functional impairment. Auxiliary liver transplantation (ALT) has been proposed as an alternative approach due to the potential advantage of preserving the native liver that could be used for future gene therapy and also serves as a back-up should the graft fail. The aim of our study was to determine if ALT has the long-term potential to correct the underlying abnormality in propionic acidemia (PA). A retrospective analysis was performed on graft function, metabolic parameters and effects on development in a child who underwent ALT for PA at our institute. The clinical and biochemical parameters are near normal with no diet restrictions and with good graft survival. A normal growth and an acceptable neurological and psychomotor development were achieved in the child. ALT is feasible and provides adequate liver mass to prevent metabolic decompensation in PA.

Ruptured hepatocellular carcinoma following chemoembolization: a western experience

BACKGROUND

Transcatheter arterial chemoembolization (TACE) is a recommended first line therapy for unresectable hepatocellular carcinoma (HCC). Serious complications such as neutropenic sepsis and hepatic decompensation are well known, but rupture of HCC following TACE is a rare and potentially fatal complication. The aim of this study was to identify the incidence of ruptured HCC following TACE and the associated risk factors.

METHODS

A retrospective analysis was performed using our liver database with key words "chemoembolization", "ruptured HCC" covering the patients who received chemoembolization from January 1995 to December 2005. There were no exclusions.

RESULTS

A total of 294 patients received chemoembolization in 530 sessions during the 10-year period. Of these, 2 ruptured following treatment (incidence 0.68%). The mean age was 65 years and the interval between the treatment and rupture was 2 and 24 days. The common factors were male sex, large tumor size (range 11-13 cm), and exophytic tumor growth. One patient died 2 days after rupture with hepatic decompensation while the second is alive after a 6-month follow up without tumor recurrence.

CONCLUSIONS

Ruptured HCC following TACE is a rare but serious complication. Large tumor size, male sex, and exophytic growth of tumor may be predisposing factors for rupture.
