Chyloperitoneum associated with idiopathic pancreatitis: case report and review of the literature

Acute chylous peritonitis is defined as the onset of acute abdomen findings due to abrupt chylous fluid accumulation in the peritoneal space. A correct diagnosis of this condition is seldom made preoperatively. The optimal management of true chylous pancreatitis depends upon the underlying etiology. Thorough lavage of the abdomen and adequate drainage has proven to be an excellent treatment modality for acute chylous peritonitis, since resolution of chylous ascites usually occurs within the next few days. However, conservative treatment may be appropriate in selected cases. We present a case report and a brief review of the literature.

Safety, efficacy, and time to clinical response with bevacizumab plus FOLFIRI regimen in metastatic colorectal cancer

e15138

Background: Bevacizumab (BEV) has shown clinical activity in metastatic colorectal cancer patients (mCRC)and randomised phase III trials have demonstrated that this agent significantly improves overall and/or progression-free survival when added to first-line irinotecan based chemotherapy (CT) regimens. We evaluated the efficacy and safety of BEV plus FOLFIRI (irinotecan, 5- fluorouracil, and leucovorin) as first line treatment in 27 consecutive metastatic colorectal cancer cases, with the primary end point to calculate the median time to clinical response with this chemotherapeutic schedule. Methods: Between October 2007 and January 2008 we collected the data on 27 patients with mCRC treated with first line chemotherapy with BEV plus FOLFIRI. Elegibility criteria had to be: mCRC; no prior CT for metastatic disease; ECOG PS 0/1, adequate organ function; no CNS metastases. The treatment consisted of a minimum of six cycles of irinotecan plus infusional 5-FU/LV according to the classical FOLFIRI schedule; BEV (5mg/kg) was given on day 1 with CT and then every 2 weeks until disease progression. Safety and response were assessed at the time of first CT and every 4 weeks thereafter. Results: 27 pts were evaluable (male 18; median age 61 years (range 45–77), ECOG PS 0: 52%, PS 1: 48%. The sites of metastases were: liver (15 pts), lung (5 pts), liver and lung (5 pts), peritoneal wall (2 pts).Median follow-up was 18 weeks. Two patients had complete response(CR) and 13 pts partial response (PR), with an overall response rate of 57.7%. Five patients had stable disease and 6 patients showed progressive disease. A clinical benefit was demonstrated in 77 % of pts. We observed a median time to clinical response of 11 weeks, evaluated with tumor markers and with CT/NMR/US examinations. A grade 3 or 4 neutropenia was detected in 39% of pts and grade 2 or 3 hypertension in 9%. We did’nt observe cases of thrombosis, bleeding and gastrointestinal perforation, sometimes related to the use of BEV. Conclusions: In this little experience the efficacy and safety of BEV associated with FOLFIRI schedule, a first line therapy in mCRC,is consistent with results from other previous studies, showing moreover a short time to clinical response with this association.

[The surgical treatment of gastric carcinoma. Evolution in surgical technique and staging in a series of 194 patients]

AIM

Surgery is, at present, the only potentially curative treatment for gastric carcinoma. The curability depends upon the extension and localization of the tumor and, particularly, the lymphatic involvement and the presence of distant metastases. The aim of this paper is to describe the personal experience during the last 2 decades and analyze the results of the surgical approach which has changed over the time.

METHODS

One-hundred and ninety-four consecutive patients have been reported (127 male and 67 female, with a median age of 65.8 years), affected by gastric carcinoma and subjected to surgical procedures from 1987 to 2000. Because of the wide period of time which it refers to, this study is overlapped by a radical change in the staging rules of gastric carcinoma, according to the publication, in 1997, of the 5th edition of the TNM. This has made necessary to divide the series into 2 different groups. The 1st group is composed of 123 patients (63.4%), staged according to TNM-1987; the 2(nd) group is composed of 71 patients (36.6%) staged according to the TNM-1997. A D1 lymphadenectomy was used as treatment protocol until 1995. Subsequently, a D2 lymphadenectomy was performed in the most part of potentially curable patients. The reconstruction after total gastrectomy was carried out in all cases with Roux technique. In distal gastrectomies a Billroth 2 technique was performed in 89.3% of the cases and a Billroth 1 technique in 10.7% of the cases.

RESULTS

The operative mortality observed on the total of patients was 1.5% (3 cases). With a median follow-up of 83 months (minimal 24, maximum 180 months), 134 patients were died, 50 are alive and 10 have been lost. The total median survival, in the 2 groups, was 24 months. We have observed a trend to improvement of survival for patients with carcinoma in stage II and III operated after 1997.

CONCLUSION

The treatment of unresectable gastric cancer, i.e. palliative surgery, is the best choice when possible in comparison to other surgical procedures (gastroenteronastomosis, jejunostomy), endoscopic procedures (dilatation, endoprosthesis, laser, percutaneous endoscopic gastrostomy) and medical therapies. In order to choose the best palliative treatment, a careful evaluation of the non-curability signs is necessary to avoid high risk surgical interventions in patients with a low expectation of life.

[Conservative surgery for ductal carcinoma in situ of the breast]

BACKGROUND

The conservative surgery is considered currently the treatment of choice for the carcinoma of the breast in the initial stage.

METHODS

From 1993 to the 2000, 46 patients (median age 52 years) affected by intraductal carcinoma of the breast, have been submitted to surgical intervention. In 10 cases (21,7%) a palpable mass was observed (mean dimension of 1.3 cm). In 36 cases (78.3%) non palpable lesions were identified by mammography (26 microcalcifications and 10 non palpable masses). All patients have been treated after stereotactic preoperatory mammographic localization of the lesions. 15 simple mastectomies, 11 mammary resections without radiotherapy and 20 mammary resections followed by radiotherapy have been performed. No patient was submitted to axillary dissection. The radiotherapy has been administered with a boost of 50 Gy on the breast.

RESULTS

At a 36 months median follow-up all the patients are alive and no local recurrence or distant metastases has been observed.

CONCLUSIONS

The treatment of choice is the local resection of neoplasm followed by radiotherapy.

[Anoplasty with House advancement flap for anal stenosis after hemorrhoidectomy. Report of a clinical case]

Anorectal strictures may occur after anorectal surgery and in particular after surgical haemorrhoidectomy. Anal examination under general anaesthesia was recommended to evaluate the stricture and to choose the appropriate technique. The house advancement flap has been recently proposed for postsurgical anal stenosis repair. The house flap receives its blood supply through unnamed vessels extending through a fatty pedicle from the underlying external sphincter muscle and not from a skin or mucosal bridge like the other common flaps (Y-V and mucosal advancement flap). The aims of this study were firstly to report a case of post-haemorrhoidectomy anal stenosis in a 68-year-old man treated in our institution by house advancement anoplasty and secondly to evaluate the efficacy and safety of this new technique. The technique was totally successful in alleviating anal stenosis and maintaining faecal continence. House advancement anoplasty should be part of the armamentarium of colon and rectal surgeons for treating severe anal stenosis.

[Complex duodenopancreatic injuries]

Injuries of the duodenopancreatic region are rare and difficult to diagnose and treat. The related high mortality is mainly due to the presence of associated lesions. Complex traumas (AAST grade IV and V lesions) require difficult surgical treatment with high postoperative morbidity and mortality rates. In a review of 200 pancreaticoduodenectomies performed for pancreatic head traumas the postoperative mortality was 31%. The authors present 6 cases of complex duodenopancreatic traumas, treated from 1995 to 1999. The aetiology was blunt trauma in 5 cases (83%) and a shotgun wound in 1 case (17%). In 3 cases, with a grade V lesion of the pancreatic head, a pancreaticoduodenectomy was performed. A case of a grade IV lesion of the tail of the pancreas was treated with distal splenopancreatectomy. Two cases of grade IV lesions of the third part of the duodenum were submitted to duodenal resection with direct anastomosis. One postoperative death was observed in a patient treated with duodenal resection. The overall mortality was 16%. A pancreatic fistula, which healed spontaneously, was observed in a case of pancreaticoduodenectomy.

[Use of endoprosthesis in the treatment of airway pathology]

In patients affected by benign or malignant inoperable airway obstructions, therapeutical options include endoscopic treatment by Nd-YAG laser therapy, tracheobronchial dilatations with rigid or flexible bronchoscope, and inflating balloon dilators. Metal self-expanding or silicone stents allow to obtain stable results. Our experience is based on the use of 14 stents (10 Dumon and 4 Wallstent) in 13 cases of stenosis either due to vegetating malignant tumours not amenable to surgery or benign stenosis. In the following 24-48 hours both subjective and objective changes of the pulmonary function, blood gas analysis and radiologic aspects were observed. The results showed an improvement in the respiratory parameters and a sensible improvement in the quality of life.

[Adrenal myelolipoma. A case report and review of the literature]

Myelolipoma is a rare benign neoplasm of the adrenal gland, histologically characterized by the presence of mature fat cells and bone marrow elements. In the international literature were reported 126 cases of adrenal myelolipoma surgically treated. The indications to surgical removal of this tumor are the presence of large symptomatic tumours, high risk of spontaneous haemorrhage, and suspicion of malignant neoplasms. The authors present a case of adrenal myelolipoma, preoperatively identified with an abdominal MNR, and surgically removed.

[Leiomyoma associated with esophageal diverticulosis]

The Authors report a case of leiomyoma located in an epi-phrenic diverticulum. The development of the leiomyoma may have weakened the esophageal wall and caused the diverticulum to appear. Surgical treatment consisted of diverticulectomy with myotomy and a Belsey MK IV antireflux procedure.
