Gastric perforation secondary to Rapunzel syndrome.

Rapunzel syndrome is rare and describes a trichobezoar that extends through the pylorus into the jejunum, ileum or even the colon. Due to the large intraluminal size and weight they can attain, acute presentations of obstruction or perforation may occur. We report a case of a 17-year-old girl who presented to the emergency department following a syncopal episode. On examination, a left upper quadrant mass was appreciated with no signs of peritonism. Contrast-enhanced CT demonstrated a giant trichobezoar with resulting gastric perforation and intra-abdominal free fluid. Laparotomy and gastrotomy were performed and the patient had an uneventful recovery with psychiatric review prior to discharge. Though uncommon, bezoars should be included in our differential diagnosis as they can present in various ways owing to their size and weight. This case illustrates the risk of gastric perforation with large gastric bezoars.

Repeat hepatectomy is independently associated with favorable long-term outcome in patients with colorectal liver metastases.

Up to three-quarters of patients undergoing liver resection for colorectal liver metastases (CRLM) develop intrahepatic recurrence. Repeat hepatic resection appears to provide the optimal chance of cure for these patients. The aim of this study was to analyze short- and long-term outcomes following index and repeat hepatectomy for CRLM. Clinicopathological data were obtained from a prospectively maintained database. Perioperative variables and outcomes were compared using the Chi-squared test. Variables associated with long-term survival following index and second hepatectomy were identified by Cox regression analyses. Over the study period, 488 patients underwent hepatic resection for CRLM, with 71 patients undergoing repeat hepatectomy. There was no significant difference in rates of morbidity (P = 0.135), major morbidity (P = 0.638), or mortality (P = 0.623) when index and second hepatectomy were compared. Performance of repeat hepatectomy was independently associated with increased overall and cancer-specific survival following index hepatectomy. Short disease-free interval between index and second hepatectomy, number of liver metastases >1, and resection of extrahepatic disease were independently associated with shortened survival following repeat resection. Repeat hepatectomy for recurrent CRLM offers short-term outcomes equivalent to those of patients undergoing index hepatectomy, while being independently associated with improved long-term patient survival.

Nephroureterectomy for emphysematous pyelonephritis: An aggressive approach is sometimes necessary. A case report and literature review.

INTRODUCTION: Emphysematous pyelonephritis (EPN) is a life-threatening urological emergency. A high index of suspicion is required for diagnosis as such patients may present to physicians with typical features of pyelonephritis. PRESENTATION OF CASE: A 67 year old lady presented atypically to the Emergency Department with symptoms of renal colic. The diagnosis of emphysematous pyelonephritis was established on prompt CT scanning. She did not respond to conservative management. Due to acute, critical deterioration, she underwent a radical right nephroureterectomy. The resected kidney involved a long segment of necrotic, gangrenous ureter. The patient had a smooth post-operative recovery and was successfully discharged. She remains well on follow-up after one year. DISCUSSION: Early radiological diagnosis is imperative for risk stratification of EPN. Current evidence recommends percutaneous catheter drainage with interval nephrectomy as the gold standard treatment. We review the literature for pathophysiology and clinical prognostic factors. This case adds onto the limited evidence base on ureteric involvement in EPN, suggesting a revision of EPN classification. CONCLUSION: Further research on ureteric involvement and treatment outcomes in EPN is required. Even in the current era of minimally invasive surgery and renal preservation therapies, early open nephrectomy still has a role in the management of EPN.

Prognostic performance of inflammation-based prognostic indices in patients with resectable colorectal liver metastases.

A range of prognostic cellular indices of the systemic inflammatory response, namely the neutrophil-lymphocyte ratio (NLR), derived NLR (dNLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), combination of platelet count and neutrophil-lymphocyte ratio (COP-NLR) and prognostic nutritional index (PNI), have been developed and found to have prognostic utility across varied malignancies. The current study is the first to examine the prognostic value of these six inflammatory scores in patients with resectable colorectal liver metastases (CRLM). Data from 302 consecutive patients undergoing surgery for resectable CRLM were evaluated. The prognostic influence of clinicopathological variables and the inflammatory scores NLR, dNLR, PLR, LMR, COP-NLR and PNI upon overall survival (OS) and cancer-specific survival (CSS) were determined by log-rank analysis and univariate and multivariate Cox regression analyses. High preoperative NLR was the only inflammatory variable independently associated with shortened OS (HR 1.769, 95 % CI 1.302-2.403, P < 0.001) or CSS (HR 1.927, 95 % CI 1.398-2.655, P < 0.001) following metastasectomy. When NLR was replaced by dNLR in analyses, high dNLR was independently associated with shortened OS (HR 1.932, 95 % CI 1.356-2.754, P < 0.001) and CSS (HR 1.807, 95 % CI 1.209-2.702, P = 0.004). The inflammatory scores PLR, LMR, COP-NLR and PNI demonstrated no independent association with either overall or cancer-specific survival in the study population. Our findings support high preoperative NLR and dNLR as independent prognostic factors for poor outcome in patients undergoing CRLM resection, with prognostic value superior to other cellular-based systemic inflammatory scores.

Upper gastrointestinal bleeding: A rare complication of acute cholecystitis.

INTRODUCTION: Haemobilia is a rare complication of acute cholecystitis and may present as upper gastrointestinal bleeding. PRESENTATION OF CASE: We describe two patients with acute cholecystitis presenting with upper gastrointestinal bleeding due to haemobilia. Bleeding from the duodenal papilla was seen at endoscopy in one case but none in the other. CT demonstrated acute cholecystitis with a pseudoaneurysm of the cystic artery in both cases. Definitive control of intracholecystic bleeding was achieved in both cases by embolisation of the cystic artery. Both patients remain symptom free. One had subsequent laparoscopic cholecystostomy and the other no surgery. DISCUSSION: Pseudoaneurysms of the cystic artery are uncommon in the setting of acute cholecystitis. OGD and CT angiography play a key role in diagnosis. Transarterial embolisation (TAE) is effective in controlling bleeding. TAE followed by interval cholecystectomy remains the treatment of choice in surgically fit patients. CONCLUSION: We highlight an unusual cause of upper GI haemorrhage. Surgeons need to be aware of this rare complication of acute cholecystitis. Immediate non-surgical management in these cases proved to be safe and effective.
