Meckel's diverticulum is an evolution of omphalomesentric channel one of the most frequent embryologic abnormality of digestive tract. It is observed in two circumstances: during a routine exploration or after a complication: intestinal obstruction, peritonitis, recurrent abdominal pain. Only open or laparoscopic explorations allow a diagnosis. Resection of the diverticulum is recommended in children because the complications are frequent and serious. The preferred therapeutic method is the bowel resection with immediate anastomosis.
INTRODUCTION Pancreaticoduodenectomy (PD) is the only curative treatment for adenocarcinoma of the pancreatic head but is associated with a significant early morbidity and a poor long term survival. Therefore, its value is still debated. The aim of this study was to evaluate early and distant results of PD for pancreatic adenocarcinoma, and to identify prognostic factors. SUMMARY Seventy-nine patients who underwent PD with curative intent for adenocarcinoma of the pancreatic head from 1982 to 2002 were studied retrospectively. The following data were evaluated: operative mortality, long-term survival, prognostic factors (through univariate and multivariate analysis), and characteristics of 5-year survivors. RESULTS Mortality rate was 1.3%. Survival at 1, 3 and 5 years was 46%, 26% and 11%. The median survival was 12 months. The prognostic factors were the T stage (T.N.M. classification) and radicality of resection. After multivariate analysis, radicality of resection was the only independent prognostic factor. Five patients survived for more than 5 years. They did not differ of the other patients but none had positive margin or venous invasion. CONCLUSIONS These results (low mortality, significant distant survival including some long term survivors) suggest that PD for pancreatic adenocarcinoma must be indicated in most low-risk patients. PD remains the only curative treatment allowing prolonged survival.
BACKGROUND Due to the relatively small number of patients involved, there is currently no consensus on what operation should be performed in patients with tertiary hyperparathyroidism after renal transplantation. METHOD Retrospective analysis of the 70 patients with tertiary hyperparathyroidism who all underwent subtotal parathyroidectomy with transcervical thymectomy in the same institution between 1978 and 2003. RESULTS The delay between transplantation and parathyroidectomy was 4,1+/-4,3 years. Follow up was available for all patients. Mean follow-up was 5,6+/-5 years. Glomerular filtration rate (GFR) was 53+/-21 ml/min at parathyroidectomy and 42+/-29 ml/min at follow-up [<30 ml/min in 26 patients (37%), 30 - 60 ml/min in 25 patients (36%) et>60 ml/min in 19 patients (27%)]. One patient was successfully reoperated for persistent tertiary hyperparathyroidism during follow-up. No patient was hypercalcemic at follow-up. Four patients with a GFR<30 ml/min had a PTH level>fourfold normal values (6%) without signs or symptoms of hyperparathyroidism. One patient was hypocalcemic (1,5%) and two patients were normocalcemic with undetectable or infranormal PTH level (3%) under oral vitamin D and calcium medication. CONCLUSION This approach permits not only to cure the majority of patients with tertiary hyperparathyroidism but also to avoid recurrence when the renal function declines. When medical management has failed, we recommend systematic subtotal parathyroidectomy with thymectomy for patients with tertiary hyperparathyroidism and this should usually be performed during the second year after transplantation.
Recurrent laryngeal nerve (RLN) injury and hypoparathyroidism can occur after thyroid surgery. The rate of RLN injury, mostly transient, ranges from 0.5% to 5% of patients. The risk is more important in patients who undergo reoperative thyroid surgery and in patients with thyroid cancer or hyperthyroidism. Rationales for technique of thyroidectomy are discussed. Meticulous and reproductive surgical technique can lower the postoperative morbidity. However, the potential for RLN injury still exists and must be explained to the patients who are candidate for thyroid surgery. The fact that this information has been delivered during the preoperative visit must be written by the surgeon in the patient's chart.
The sternalis muscle is a normal anatomic variant, which exists in about 5 to 8% of people. It runs longitudinally superficial to pectoralis major, alongside the sternum. Although the sternalis seems common in cadaveric studies, physicians are not familiar with it, which may lead to confusion in diagnosis. Occasionally, the sternalis may be misinterpreted as a breast mass on mammogramm. In that case, computed tomography and magnetic resonance imaging are useful. We report herein two cases of sternalis muscles encountered during mastectomy.
The authors report two cases of von Meyenburg complexes disease found during laparoscopic surgical procedures. The first patient (41 years old) had multiple gallbladder stones with recurrent hepatic colics. The second patient (45 years old) had gastroesophageal reflux with recurrent peptic esophagitis. In both cases, multiple millimetric and superficial hepatic lesions were found during the exploration of the abdominal cavity. Then, an hepatic biopsy was done because the macroscopic aspect should suspect secondary metastatic lesions. Histological result made the diagnosis of von Meyenburg complexes disease (biliary microhamartomas). It seems to be important to know this anomaly of the ductal plate development and to do a liver biopsy during laparoscopy to affirm the diagnosis and cancel the diagnosis of multiple hepatic metastasis. In fact, this congenital pathology could be associated with increased risk of cholangiocarcinoma of the liver. The modality of radiological monitoring still remains to be defined.
Surgical management of an intractable postpartum haemorrhage after failure of medical and obstetric measures is not limited to the emergency peripartum hysterectomy. Uterine atony and abnormal placental insertions are the major causes of primary postpartum haemorrhages. Involving mostly young women, having few or no child, before with a healthy uterus, in first intention conservative option is recommended. The simplest methods must be known and be applied. It will be essentially progressive uterine arteries' ligation, which can be adapted to the majority of situations. Internal iliac arteries' ligation is a little less effective and technically more difficult to carry out. It remains interesting in obstetrical traumatic hurts, which do not concern the uterus. New and easier surgical methods, such as uterine compression or hemostatic suturing techniques have been described for which we lack experience. The quality of the result depends of the length of intervention and the cause of the bleeding. Nevertheless the main cause of failure with conservative treatments is placenta accreta. In case of failure of a conservative treatment, it would be dangerous to multiply techniques. Emergency peripartum hysterectomy then should remain the choice procedure.
Accurate mark of macrobiopsy site, carried out borderline or malignant lesions, is very important for surgeons. We report a woman case, 68 year's old, who presents intraductal carcinoma diagnoses on macrobiopsy. On postbiopsy X-ray, we can note lipiodol used instead of clip to reaper macrobiopsy site. Our observation shows how lipiodol use is not adapted into this indication.
We report a case of entire of small bowel necrosis due to internal herniation through a mesenteric rent around the Roux-en-Y anastomosis. For prevention of internal herniation around the Roux-en-Y limb, secure closing of the mesenteric is recommended. Nevertheless, the consequences of a mesenteric closing defect are rarely reported. Necrosis of the entire small has never been described yet.

Crohn's disease may involve any part of the alimentary tract, including the stomach and duodenum. We report herein the case of a 22 year-old male in whom Crohn disease was diagnosed due to weight loss in relation with a stenosis of the first and second parts of the duodenum. A gastrojejunostomy was performed with a good subsequent result. The initial management of a Crohn's disease with involvement of the duodenum is medical. When there is an indication for surgery, a gastroenterostomy is preferred, albeit with a high incidence of outlet obstruction and marginal ulceration.
Gastrointestinal stromal tumors (GIST) are mesenchymal tumors that arise from the wall of the gastrointestinal tract expressing CD117 and/or the CD34. Similar tumors were described in the soft tissue of the abdomen and are so-called extragastrointestinal stromal tumors (EGIST). We report 4 new cases of EGIST. The tumors occurred in 2 women and 2 men, who ranged in age from 42 to 71 years. Three tumors arose from the soft tissue of the abdominal cavity, and the remainder arose from the retroperitoneum. They ranged in size from 10 to 27 cm. Three cases were composed purely of short fusiform cells tumors, the last case showed an epithelioid pattern. All the tumors expressed CD117. One patient presented with local recurrence and metastasis, one was lost to the follow-up and two patients were doing well. Immunohistochemistry is useful in distinguishing EGIST from other mesenchymal tumors. Intra-abdominal aggressive fibromatosis may express actin and CD117 but catenin is also positive, leiomyosarcoma expresses the actin and/or desmin but CD117 is usually negative, retroperitoneal dedifferentiated liposarcoma is CD117 negative and PS 100 positive, inflammatory myofibroblastic tumor is negative for CD117 and CD34. The solitary fibrous tumor expresses CD34 and is negative to CD117. Some tumors expressing CD117 such desmoplastic round cell tumor should not be confused with EGIST. On the occasion of these four observations, we will discuss the clinical aspects and the main differential diagnoses of this tumor. (c) 2006 Elsevier SAS. Tons droits reserves.
Pulmonary sequestration is a rare congenital malformation that receives its blood supply from a systemic artery. We report a case of pulmonary sequestration treated by ligature of the anomalous artery without pulmonary resection. Pulmonary sequestration must be treated surgically before the occurrence of severe complications.
