Adreno-cortical oncocytoma: a case report.

BACKGROUND: Adrenal oncocytoma is a very rare lesion, non functioning and benignin most cases. Only 46 cases have been reported in the medical literature. AIM: This study aimed to report a new case of adrenal oncocytic tumor with uncertain malignant potential. CASE: A 72 year-old- man, consulted for renal fossa pain. Ultrasonography and omputed tomography scan revealed a large mass in the right adrenal gland with extension to the right kidney. A right adrenalectomy and nephrectomy was performed. The diagnosis of adrenal oncocytoma with malignant potential was confirmed by pathology. Patient had a well recovery and left hospital on the fifth day post operatively. He was followed up for 8 months, no tumor recurrence detected. CONCLUSION: Adreno cortical oncocytoma is a rare tumor. The majority of reported cases had good prognosis.

[Parietal abscess revealing a lost gallstone 8 years after laparoscopic cholecystectomy]. / Abcès pariétal fistulisé révèlant des calculs oubliés huit ans après une cholécystectomie laparoscopique.

BACKGROUND: Laparoscopic cholecystectomy is the treatment of choice for symptomatic gall stone disease. The perforation of the gallbladder happens in 40% of cases. Stones spilled remain there in 20% of cases in view of their number and location. These lost stones can cause adhesions, abscess, peritonitis, digestive fistula or else cutaneous fistula. AIM: to report a new observation of a cutaneous fistula resulting from a gallstone lost during laparoscopic cholecystectomy, eight year later. CASE: A 57-year-old women, underwent 8 years ago laparoscopic cholecystectomy for acute cholecystitis. A cholecystectomy was performed without incidence and with uneventful post-operative course. She was admitted to hospital again for an inflammatory painful swelling of the right renal fossa which had been developing for one week without any fever or transit disorder. The abdominal C.T. scan performed revealed a subcutaneous collection of 8 CM. She underwent an excision of the collection with drainage of pus and numerous small stones. She was diagnosed with lost gallstone complicated with cutaneous fistula. The control C.T. scan made 3 months later showed a small collection at the level of the right parieto-colic gutter. She was operated on again, laparoscopy excision of the fistulous tract was performed without showing stones. Healing was achieved two months later. She re-presented 3 months later for a swelling of the old scar which fistulized spontaneously with pus leaking. The abdominal CT scan was normal. She underwent an excision of a collection wish containing a large stone of two centimetres. The patient was regularly seen afterwards at the outpatients' department. She was feeling well 18 months later. CONCLUSION: A lost gallstone can cause serious complications. Spillage of gallstones should be avoided. When does occur, every effort should be made to withdraw spilled gallstones and especially to mention the event in the post-operative report.

[Laparascopic cholecystectomy on a previously operated abdomen]. / Les choléystectomies sous coelioscopie sur abdomen cicatriciel.

BACKGROUND: Laparoscopic cholecystectomy is the "gold standard" reference treatment of gall bladder stones. Laparoscopy is still contra-indicated in the presence of abdominal scars due to the frequent post-operative adhesions which make access to the peritoneal cavity difficult. AIM: This study aimed to assess outcomes of laparoscopic cholecystectomy on a scarred abdomen. METHODS: We have carried out a retrospective study on a number of consecutive patients operated between the first januar 2000 and 31 december 2006, who underwent laparoscopic cholecystectomy with previous abdominal surgery (one or several) during this period, laparoscopic cholecystectomy was performed on 2281 patients, including 233 patients who had at least one abdominal scar (10%). We have noted on the records of these patients all the data relating to the epidemiological, clinical and therapeutical aspects. We have worked out a descriptive analysis of the series and we have thus studied the rate of operative and post-operative complications, the rate of conversion, the duration of the operation and the duration of post-operative stay. Then we have compared two groups of patients, those with an upper abdominal surgery: group 1 (G1) and those with lower abdominal surgery: group 2 (G2). RESULTS: The groups consist of 200 women and 33 men aged on average 13.8 +/- 49.6 years. The indication for cholecystectomy was a symptomatic cholelithiasis in 78% of cases (n = 181), an acute cholecystitis in 22% of cases. The adhesions were believed numerous or very numerous in only 46 patients (20%). Four patients had interventional adverse events: a small intestine injury, a choledoch injury, a gastric injury and a least known colic injury. The rate of open conversion was 2.1%. Post-operative complication was 2.1%. The evolution was satisfactory in all cases. Mean operating time was 50 minutes (15-230). Mean post operative stay was one day (1-29 days). When comparing the above mentioned two groups of patients (G1: 45 patients and G 2: 188 patients), we can conclude that the first group (G1) is made up of more male patients aged over 60 years (p < 10-3). It also appears that the existence of an upper umbilical scar is correlated to a greater number of adhesions (p < 10-3), an increased risk of operative complications (p = 0.01), a greater conversion rate (p < 10-4), a prolonged operating time (p < 10-3) and a longer stay (p = 0.017). On the other hand, post-operative complications was similar in group 1 and 2. CONCLUSION: Previous abdominal operations, are not a contraindication to safe laparoscopic cholecystectomy. However, previous upper abdominal surgery is associated with a higher rate of adhesions, an increased risk of operative complications, a greater conversion rate, a prolonged operating time and longer stay.

Acinar cell carcinoma of the pancreas in a young patient with chronic pancreatitis.

BACKGROUND: Acinar cell carcinoma (ACC) is a rare malignancy of the pancreas arising from acinar cells. Unlike ductal adenocarcinoma, this tumor rarely presents with pancreatitis. METHODS: We present a case of ACC associated with chronic calcifying pancreatitis, and a review of the literature focusing on diagnosis and management. RESULTS: A 43-year-old man was proposed for Wirsungojejunal derivation for chronic pancreatitis. Histopathological examination of the tissue extracted revealed an ACC. Duodenopancreatectomy was performed. Six months post-operatively, the patient developed hepatic metastasis and was treated with gemcitabine as palliative chemotherapy. CONCLUSIONS: The clinical presentation of ACC of the pancreas is not specific and the tumor can be under-diagnosed when associated with chronic pancreatitis. Data regarding course, treatment, and prognosis of this tumor are generally lacking.
