Predictive factors of Gastrointestinal motility Dysfunction after gastrojejunostomy for peptic ulcer stenosis.

BACKGROUND: Despite the establishment of effective medical therapies in peptic ulcer disease, gastric outlet obstruction remains one of the most common health problem in Tunisia. Various operations have been attempted, which may lead to postoperative morbidity. Gastrointestinal (GI) motility dysfunction is the most common complications. AIM: to determine the predictive factor of gastrointestinal motility dysfunction after gastrojejunostomy for peptic ulcer stenosis. METHODS: We carried out a retrospective study to evaluate the postoperative recovery of the motility of the upper gastrointestinal tract after gastrojejunostomy for peptic ulcer stenosis. During the 9- year study, 138 patients underwent operations for ulcer peptic stenosis. Among the patients, 116 (84,1%) were treated with gastrojejunostomy. Descriptive statistics, univariate and multivariate analyses were performed. RESULTS: The mean age of patients was 47.85 years (range: 19- 92years) and most. Were male (84, 5 %). Ninety two (79.3%) patients had a documented history of peptic ulcer disease. The duration of symptoms ranged from 10 to 372 days (mean: 135.86 days). Eighty two (71%) patients were operated on through laparotomy. Laparoscopic procedure was performed in 29% of the patients. There was no operative mortality. Perioperative morbidity occurred in 12.4% (14 patients). Gastrointestinal motility dysfunction occurred in 12 patients (10.3%). It was treated by nasogastric aspiration and prokinetics. By univariate analysis; diabetes (0,010), cachexia (0,049), ASA class (0.05) were all statistically associated with gastrointestinal motility dysfunction in this series. Multivariate logistic regression analysis (table 2) showed that the cachexia (0,009), ASA class (0.02) were the main predictors of gastrointestinal motility dysfunction after gastrojejunostomy for peptic ulcer stenosis in the followed patients. CONCLUSION: Gastrointestinal motility dysfunction is the most common complications after gastrojejunostomy for pyloric adult stenosis. Surgery must be preceded by careful medical preparation. It is more likely to occur in patients with an ASA class 2 or greater. Those patients should be considered for other treatment options, such as endoscopic balloon dilation.

Ischemic colitis revealing polyarteritis nodosa.

Ischemic colitis is one of the most common intestinal ischemic injuries. It results from impaired perfusion of blood to the bowel and is rarely caused by vasculitis. We report a case of ischemic colitis revealing polyarteritis nodosa (PAN) in a 55-year-old man. Histological examination of the resected colon led to the diagnosis of PAN.

Prognostic factors in gastric carcinoma after R0 resection with DII lymph node dissection. Tunisian experience.

BACKGROUND: Curative resection with adequate lymph node dissection is the treatment of choice for gastric cancer. AIM: To determine the prognostic factors after R0 resection with DII lymph node dissection. METHODS: We retrospectively assessed 126 patients who underwent R0 resection with DII lymph node dissection for gastric cancer (excluding the upper third of the stomach) in a single institution between 1991 and 2006 with median follow-up of 38.5 months (6 - 219). Prognostic factors were assessed by Cox proportional hazard model. RESULTS: There were 45 women and 81 men. The median age was 60 years (21 - 87). Four patients died (3.2 %). Postoperative hospital morbidity was 16.7 %. The pathologic review of the slides revealed that 50% of the tumors were stage T3 (63 cases). The median number of lymph node removed was 11 (8-40), 50% were involved. Five and 10 years survival rates were respectively 56.9 % and 40.2 %. In multivariable analysis, depth of wall invasion, lymph node involvement and more than 15 retrieved lymph nodes were found to be independent prognosis factors. CONCLUSION: After R0 resection with DII lymphadenectomy, depth of wall invasion, lymph node involvement and more than 15 retrieved lymph nodes were independent predictive factors for survival.

Risk factors associated with pancreatic fistula after distal pancreatectomy.

BACKGROUND: Pancreatic leak (PL) remains a major cause of postoperative morbidity in patients undergoing pancreatic resection. AIM: To identify risk factors related to pancreatic fistula in patients undergoing distal pancreatectomy (DP). METHODS: 35 patients underwent DP during a 10-year period (2000- 2009). Informations regarding diagnosis, operative details, and perioperative morbidity and mortality were collected. Nine risk factors were examined. RESULTS: Indications for DP included primary pancreatic disease (n=23; 66 %) and non-pancreatic disease (n = 12; 34 %). Postoperative morbidity rate was 43 % and none patient died. No patients required a reoperation. Pancreatic fistula was occurred in 11 patients (31 %). On univariate analysis, incidence of pancreatic fistula rate was not significantly associated with these risk factors: pathology, use of prophylactic octreotide therapy, concomitant splenectomy, additional procedures, intra operative bleeding and texture of pancreatic parenchyma. We observed significant statistical difference between male and female, 47 % of females experienced a pancreatic fistula, while 17 % males developed a pancreatic leakage (p =0.05). The role of the technique of pancreatic stump closure in the development of pancreatic leak remains unclear because of the few number of patients on who we used stapler. CONCLUSION: The rate of pancreatic fistula after left pancreatectomy is 31 %. The female was identified as a risk factor for occurrence of pancreatic fistula after left pancreatectomy. The role implicated in the use of a mechanical claw for the treatment of pancreatic stump requires a larger number of patients to conclude. The body mass index has not been studied in our series.

[Totally implantable venous access ports by cephalic vein cut-down for patients receiving chemotherapy]. / Impact thérapeutique de l'utilisation de la veine céphalique pour la mise en place des chambres implantables pour chimiothérapie.

BACKGROUND: The use of an implantable room has become indispensable in the clinical practice for the cancer patients. The increasing use of these devices was associated with a greater incidence of complications. AIM: To verify the feasibility of the cephalic vein cut-down technique for placement of venous access devices. METHODS: A prospective study of 58 port placements was performed at our department of general surgery. The surveillance of devices was collectively insured by the operator and by the oncologists. RESULTS: The indication for implantation was the infusion of intravenous chemotherapy in patients with colorectal cancer in 55.1% cases and breast cancer in 27.5%. The specific complication rate was 7%. The cephalic vein cut-down approach was used successful in 45 (77.5%) patients. When the cephalic vein could not be used, a percutaneous technique was employed using the subclavian vein in 22.4% of the patients. CONCLUSION: Cephalic vein cut-down technique should be considered a safe and feasible approach for placement of venous access devices.

[Anatomic variations of the hepatic artery : a study of 33 cases and review]. / Variations anatomiques de l'artère hépatique et applications pratiques: a propos de 33 cas et revue de la littérature.

BACKGROUND: The hepatic artery is prone to numerous anatomic variations dictated by certain variables of the organogenesis. Aim : To research study the anatomic variations of the hepatic artery as well as their implications within surgical practice. METHODS: Study of a post-mortem series of 33 cases of dissection of the hepatic pedicle with fresh corpses (deaths amounting no longer than 24 hours), carried out in conditions that are quite close to those met with the living ones. RESULTS: The common hepatic artery was divided at the foot of the hepatic pedicle into a gastro duodenal artery and into a proper hepatic artery in 94% of the cases. In 6% of the cases, we noticed a three level change, a branching of the average hepatic artery into a gastro duodenal artery, a right hepatic artery and a left hepatic artery. The proper hepatic artery represented the pedicle segment of the hepatic artery in 94% of the cases. In 36% of the cases, the liver was irrigated by two hepatic arteries. In 12% of the cases, there was the matter of the right hepatic artery, branch of the mesenteric artery. In 24% of the cases, there was the matter of the left hepatic artery branch of the left gastric artery. CONCLUSION: The perfect knowledge in preoperative and preoperative stages of the anatomic variations of the hepatic pedicle is quite essential. Actually, the lack of knowledge of these variations exposes to the risk of certain complications which are sometimes deadly during hepatic transplants, pancreatic surgery, cholecystectomies, through laroscopic way as well as in the treatment of gastro-esophagus surging.

[Colo-urachal-cutaneous fistula in an adult]. / Fistule colo-cutanée d'origine allantoïde chez un adulte

BACKGROUND: An infected urachal cyst is an uncommon finding in adults. AIM: To report a case of a sigmoid- urachal- cutaneous fistula. CASE REPORT: A 51 years old adult male presented with fecaloid leaking from rupture of an infected urachal cyst. Definitive management consisted of resection of the urachus with a bladder cuff, along with removal of the affected bowel segments. CONCLUSION: Colo-urachal-cutaneous fistula is a rare condition; its management is rather complex.

[Malignant intraductal papillary mucinous tumours of the pancreas. A three cases report]. / Tumeurs intracanalaires papillaires et mucineuses dégénérées du pancréas: à propos de trois cas.

BACKGROUND: Intra ductal papillary mucinous tumors of pancreas are rare and are characterized by a risk of malignant transformation. AIM: To clarify their clinical presentation and the performance of different imaging examinations to determine their benign or malignant and achieve their staging. CASES: We report three cases of degenerate intra ductal papillary mucinous tumors of pancreas. The combination of CT, the pancreato- MRI and duodenoscopy has led to the diagnosis in all cases. A pancreaticoduodenectomy were performed in two cases. CONCLUSION: The various imaging techniques allow better detection and analysis of the tumor including the evaluation criteria of degeneration. The treatment of these lesions is still surgery.

[Acute peritonitis complicating Crohn's disease: epidemiologic and physiopathological characteristics]. / Peritomite aigue generalisee compliquant une maladie de Crohn: aspects epidemiologiques et physiopathologiques.

BACKGROUND: An uncommon event in the natural course of Crohn's disease is the spontaneous perforation. It's the most serious intestinal complication. AIM: To report the incidence of this complication and to discuss the mechanism of the perforation. OBSERVATIONS: We report, retrospectively, 4 cases (3 men and one woman; median age: 30 years) of peritonitis complicating Crohn's disease and study their clinical characteristics intra operatively findings and course evolution. Steroid therapy was administrated to all patients before the perforation. The perforation sites are on the ileum in three cases and on the jejunum in one case. The treatment consists in a resection of the perforated intestine with stoma in all cases. CONCLUSION: Perforation in Crohn's disease is a rare event. The exact mechanism of the perforation is still unknown and many hypotheses are presented.

Acinar cell carcinoma of the pancreas: a rare tumor with a particular clinical and paraclinical presentation.

Acinar cell carcinoma (ACC) of the pancreas is a rare tumor with an extremely low incidence rate. While the number of reported patients with ACC is relatively small, a long-term survival rate has been noted in patients with neuroendocrine differentiation. A 39-year-old woman visited our emergency department for upper gastrointestinal bleeding. Endoscopy indicated extrinsic compression of the posterior body of the stomach, together with a large, 10-cm, central ulcer covered with necrotic tissue. Abdominal computed tomography (CT) indicated a lesion that involved the whole of the pancreas, with a fistula in the stomach, which was suspected of being a degenerative intraductal papillary mucinous tumor of the pancreas. Magnetic resonance imaging (MRI) of the pancreas was performed, and the results further strengthened our suspicions by demonstrating the presence of cystic lesions and tumor buds. A total duodenopancreatectomy, including total splenectomy and gastrectomy, was performed, along with two independent Roux-en-Y anastomoses (one esojejunal and one hepaticojejunal). The tumor also had a wide opening in the stomach. The patient's postoperative course was marked by partial thrombosis of the portal vein, which was treated medically. Histopathological examination provided evidence of pancreatic ACC. The diagnosis of ACC should be considered in the presence of cutaneous lesions, which were absent in the case of our patient, and colonoscopy is also highly desirable because of the various forms associated with familial adenomatous polyposis. The prognosis, which includes a 5-year survival rate of 45%, in the population with an R0 resection is better than that for ductular adenocarcinoma, thus prompting the more aggressive management of this type of tumor.
