Emergency surgery for Crohn's disease.

BACKGROUND: Surgery has played an essential role in the treatment of Crohn's disease. Emergency can reveal previously unknown complications whose treatment affects prognosis. PURPOSE OF STUDY: Indicate the incidence of indications in emergent surgery for Crohn's disease. Specify the types of procedures performed in these cases and assess the Results of emergency surgery for Crohn's disease postoperatively,  in short , medium and long term. METHODS: Retrospective analysis of collected data of 38 patients, who underwent surgical resection for Crohn's disease during a period of 19 years from 1992 to 2011 at the department of surgery in MONGI SLIM Hospital, and among them 17 patients underwent emergency surgery for Crohn's disease. In addition to socio-demographic characteristics and clinical presentations of our study population, we evaluated the indications, the type of intervention, duration of evolution preoperative and postoperative complications and overall prognosis of the disease. RESULTS: Of the 38 patients with Crohn's disease requiring surgical intervention, 17/38 patients underwent emergency surgery. Crohn's disease was inaugurated by the complications requiring emergency surgery in 11 patients. The mean duration of symptoms prior to surgery was 1.5 year. The most common indication for emergency surgery was acute intestinal obstruction (n=6) followed by perforation and peritonitis (n=5). A misdiagnosis of appendicitis was found in 4 patients and a complicated severe acute colitis for undiagnosed Crohn's disease was found in 2 cases. The open conventional surgery was performed for 15 patients. Ileocolic resection was the most used intervention. There was one perioperative mortality and 5 postoperative morbidities. The mean of postoperative hospital stay was 14 days (range 4-60 days). Six patients required a second operation during the follow-up period. CONCLUSION: The incidence of emergency surgery for Crohn's disease in our experience was high (17/38 patients), and is not as rare as the published estimates. Emergency surgical indication could be frequently the first presentation of Crohn's disease.  Acute intestinal obstruction and perforation-peritonitis were the most common indications for emergent surgery in Crohn's disease in our study.

Surgical treatment of Crohn's disease: indications, results and predictive factors of recurrence and morbidity.

BACKGROUND: Crohn's disease management represents a major problem in gastroenterology and general surgery because it affects young subjects and has a major impact on their quality of life. The aims of our study were to identify the indications for surgery in Crohn's disease, the results and the complications of surgery in our series, and to identify possible predictive factors of recurrence and postoperative morbidity. METHODS: A retrospective descriptive study including 38 cases of patients with Crohn's disease who underwent surgical treatment in the department of surgery in Mongi Slim Hospital, during the period between January 1992 and December 2011 was performed. RESULTS: The occurrence of stenosis was the most common indication for surgical treatment in Crohn's disease in our series, and ileocecal resection was the most performed surgery. Twenty six patients (58%) received maintenance therapy after surgery. Twenty two patients relapsed and 13 had surgical management for recurrence. In univariate analysis, predictive factors of post operative morbidity in our study were leukocytosis, penetrating phenotype and intraabdominal sepsis. Ileocecal location was the only factor that significantly improved the incidence of recurrence. In multivariate analysis, only penetrating phenotype was a predictive factor or post operative morbidity. CONCLUSION: Despite the development of medical treatment, surgical treatment keeps large indications for the management of complications of Crohn's disease. The surgery should be an alternative to immunosuppressive therapy. Currently, prevention postoperative recurrence is well codified, reducing the risk of complications.

Solid pseudopapillary tumor of the pancreas with concomitant Bochdalek's hernia. The first reported case.

BACKGROUND: Solid pseudopapillary tumors of the pancreas are rare. The diagnosis is difficult because of its clinical and radiological polymorphism. It was described in the literature that this entity can be associated with congenital malformation. We report an exceptional case associating solid pseudopapillary tumor of the pancreas to Bochdalek's hernia. CASE REPORT: A 31 year-old woman presented with abdominal pain. Radiological findings (ultrasound, CT scan, MRI) showed a heterogeneous mass evoking a stromal tumor of duodenal origin associated to a hernia through the foramen of Bochdalek. The patient underwent tumorectomy without lymphadenectomy with a hernia repair. Pathology report confirmed the diagnosis of solid pseudopapillary tumor of the pancreas. The 3-years follow- up was uneventful. CONCLUSION: Solid pseudopapillary tumor of the pancreas is a rare benign tumor with a good prognosis after resection. Recognition of the association of congenital malformation with solid pseudopapillary tumor of the pancreas is useful as it could have implications on the diagnosis and treatment.

[Solitary rectal ulcer syndrome. A Tunisian monocentric Survey]. / Le syndrome d'ulcère solitaire du rectum. A propos d'une série Tunisienne monocentrique.

BACKGROUND: Solitary rectal ulcer syndrome is an uncommon and benign defecation disorder. Occidental series are scarce and to our knowledge, Tunisian data are not available. AIMS: The aim of this study was to evaluate the clinical, endoscopic and histological spectrum of the solitary rectal ulcer syndrome. METHODS: All the patients diagnosed with solitary rectal ulcer syndrome from January 2001 to 2012 were included in the study. The medical records were reviewed retrospectively to evaluate the clinical spectrum of the patients along with the endoscopic, histological and therapeutic findings. RESULTS: A total of 15 patients were evaluated: 7 males; mean age 42.6 years. Bleeding per rectum was present in 66% and dyschezia in 73%. Endoscopically, solitary lesion was present in 66% patients. The most frequent dynamic abnormalities shown by defecography were of rectal intussusception (53%). Anorectal manometry was performed in seven cases disclosing dyssynergia in 2 cases. Thirty patients underwent surgery, always after failure of medical treatment and one patient was treated with biofeedback. Rectopexy was the most utilized technic. After a mean follow-up of 29 months, total regression of symptoms was noted in 50% of patients who underwent surgery. CONCLUSION: In this cohort, diagnostic and therapeutic spectrum of solitary rectal ulcer syndrome was comparable to occidental features. Nevertheless, accesses to manometry and defecography as well as biofeedback were limited.

[What's new in rectal cancer?]. / Quoi de neuf dans le cancer du rectum?

BACKGROUND: In recent years, multidisciplinary therapeutic management of rectal cancer has evolved. This progress had interest radio and chemotherapy. AIM: To describe the main spots of the progress in the therapeutic strategies of the disease, surgical techniques and standardization of these techniques, particularly regarding locoregional extension in the mesorectum. METHOD: Literature review. RESULTS: Treatment of rectal cancer is multidisciplinary. On the surgical field, excision of the mesorectum (total mesorectal excision [TME]) has reduced local recurrence and the genitourinary sequelae. Meanwhile, chemoradiotherapy has become important. The standard now is to indicate to T3 T4 N+ tumors to decrease local recurrence without improving survival, however. CONCLUSION: Advances in the management of rectal cancer with both imaging progress and therapeutic modalities have improved the prognosis and survival of this cancer.

A misleading hepatic tumour: epithelioid angiomyolipoma.

Hepatic angiomyolipoma (HAML) is a rare, benign mesenchymal neoplasm composed of varying amounts of smooth muscle cells, adipose tissue, and vessels. Its morphological diversity often poses diagnostic problems. In this paper, the authors report a peculiar case of epithelioid HAML mimicking histologically hepatocellular carcinoma with focal areas resembling inflammatory pseudotumour. A 57 year-old male patient presented with abdominal pain and discomfort. Non enhanced CT scan demonstrated a heterogeneous hypodense mass located in segment II and IV of the liver. Hepatocellular carcinoma was suspected and the patient underwent left lobectomy. Histologically, the tumour was mainly composed of epithelioid cells arranged in trabeculae and sheets (50% of the tumour surface) admixed with mature fat cells (20%) and thick-walled blood vessels. Lymphocytic aggregates and clusters of foamy histiocytes were focally found in the stroma (30%). Most of the epithelioid tumour cells were immunoreactive to homatropine methylbromide 45 (HMB-45) and smooth muscle actin. Morphological pattern and immunophenotype were consistent with epithelioid HAML.

Pseudotumoral autoimmune pancreatitis mimicking a pancreatic cancer: a very difficult disease to diagnose.

Autoimmune pancreatitis (AIP) is a rare disorder, although the exact prevalence is still unkown. It is a type of pancreatitis that is presumed to have an autoimmune aetiology, and is currently diagnosed based on a combination of 5 criteria. However, in this day and age, some patients with AIP are likely to be resected for the suspicion of malignancy. The authors report a case of pseudo-tumoral autoimmune pancreatitis, reviewing some literature about it and underlining the difficulty in the diagnosis. A 56-year-old patient was referred to our unit for upper abdominal pain. In his past medical history we note mellitus diabetes. The clinical examination was unremarkable. Laboratory data showed no abnormal values. Upper endoscopy showed antral gastritis. Transabdominal ultrasonography showed a hepatic steatosis and 5 angiomas. No computed tomography scan was made. Magnetic resonance imaging (MRI) showed 5 angiomas and a lesion of 20×20 mm of the pancreatic tail with decreased signal intensity on T1-weighted MR images, increased signal intensity on T2-weighted MR images. Due to concerns of pancreatic malignancy, the patient underwent open distal spleno-pancreatectomy. Histolo gical analysis of the resected specimen revealed no malignancy. Postoperatively, immunoglobulin G fraction 4 was slightly above of the upper limit of the normal range. After corticotherapy the patient is getting better. This case underlines the difficulties still encountered in the diagnosis of AIP. It has been frequently misdiagnosed as pancreatic cancer and caused unnecessary resection. In order to avoid unnecessary resections for an otherwise benign and easily treatable condition, it is urgent to refine diagnostic criteria and to reach an international consensus.

Pancreaticoduodenectomy in the elderly over 80 years: a case report.

BACKGROUND: An increasing number of elderly patients have been considered for major surgical procedures, such as pancreaticoduodenectomy. The decision to recommend this operation for localized pancreatic cancer or other periampullary process in a very elderly patient is complicated by the frailty of the patient and the poor prognosis of the disease. Moreover, increased surgical experience associated with better patient selection may reduce the mortality rate, even in very elderly patients (over 80 years of age), after pancreaticoduodenectomy. METHODS: An 84-year-old woman underwent pancreaticoduodenectomy for ampullary adenocarcinoma. The tumor was classified pT3N0M0. RESULT: A good postoperative outcome was obtained. The patient is still alive, 18 months after operation. CONCLUSIONS: Radical resection of periampullary tumors is safe in selected patients of advanced age, with morbidity and mortality rates approaching those observed in younger patients. Age alone should not be a contraindication for pancreatic resection.
