Palliative resection for advanced gastric and junctional adenocarcinoma: which patients will benefit from surgery?

BACKGROUND

Whereas palliative chemotherapy offers a median survival of approximately 10 months in advanced gastric and junctional adenocarcinoma (AGJA), the survival impact of primary tumor resection is controversial. Our purpose was to identify which AGJA patients benefit from palliative resection.

METHODS

In 3,202 AGJA patients scheduled for surgery in 21 French centers between 1997 and 2010, prognostic factors were identified in palliative group and the impact of each combination of these factors on survival was studied.

RESULTS

Surgery was defined as palliative due to solid organ metastasis (5.6 %), localized (4.6 %) or diffuse (2.3 %) peritoneal carcinomatosis (PC), or incomplete tumoral resection (12.8 %). Median survival of AGJA patients resected with a palliative intent (n = 677) was longer than in nonresected patients (n = 532; 11.9 vs. 8.5 months, P < 0.001). Multivariable analyses identified ASA score III-IV (P < 0.001) as a predictor of postoperative mortality and solid organ metastasis (P = 0.009), localized PC (P = 0.004), diffuse PC (P = 0.046), and signet ring cell histology (SRC; P = 0.02) as predictors of survival. Only ASA I-II patients with incomplete resection without metastasis or PC, one site solid organ metastasis without PC, or localized PC without SRC had a survival benefit after palliative surgery with median survivals from 12.0 to 18.3 months. Nonresected ASA I-II patients with same risk factors had median survivals from 3.5 to 8.8 months (P < 0.05 for each).

CONCLUSIONS

In AGJA, patient and tumor-related factors should be used to select candidates for palliative surgery in association with chemotherapy.

Should pancreaticoduodenectomy be performed in the elderly?

BACKGROUND/AIMS

Pancreaticoduodenectomy (PD) is indicated in benign or malignant pancreatic head diseases. It is a difficult operation with high morbidity especially in elderly patients. The aim of our study was to determine whether pancreaticoduodenectomy is associated with higher morbidity and mortality in patients ≥ 70 years old.

METHODOLOGY

During 17 years, 173 patients were operated by Whipple intervention, whatever the disease. From a prospective database, patients were divided in 2 groups (Group A ≥ 70 years old, Group B <70).

RESULTS

Postoperative mortality was not significantly higher in elderly (12% vs. 4.1%; p=0.06). However, re-intervention and morbidity were more important in univariate analysis (p=0.03 and p=0.002 respectively). In multivariate analysis, age ≥ 70 years old was not an independent prognostic factor of mortality (p=0.27) and re-intervention (p=0.07). Whereas age (p=0.04) and preoperative morbidity (p=0.02) were independent prognostic factors of morbidity.

CONCLUSIONS

PD requires careful patient selection. However, age should not be a limiting factor.

Intraperitoneal mesh repair of small ventral abdominal wall hernias with a Ventralex hernia patch

BACKGROUND

Various surgical procedures have been described in the treatment of small ventral abdominal wall hernias. Mesh repair is becoming popular because of a low recurrence rate.

AIM

The aim of this prospective study was to evaluate an open intraperitoneal technique using the Bard Ventralex hernia patch in the treatment of small midline ventral hernias.

METHODS

101 patients were operated on (59 male, 42 female) with a mean age of 54.5 years (range 17-85). Mean operative time was 33 min (range 16-65). The median hospital stay was 2 days (range 1-15).

RESULTS

Two patients had a hematoma without wound infection. There were 2 recurrences (2%). Mean postoperative follow-up time was 28.5 months (range 6-55).

CONCLUSIONS

Our preliminary results suggest that Ventralex hernia patch repair for ventral hernias can be performed with minimal postoperative morbidity and a low recurrence rate.

Prognostic factors of survival in repeat liver resection for recurrent colorectal metastases: review of sixty-two cases treated at a single institution

PURPOSE

Liver metastases develop in 50 percent of patients with colorectal carcinoma. Recurrent liver disease is usual. Repeat liver resection remains the only curative treatment. The aim of this study was to review our data on repeat hepatectomy and to analyze potential prognostic factors of survival.

METHOD

Patients who underwent repeat liver resection for metastases of colorectal carcinoma between January 1992 and August 2007 were identified from a prospective database and their medical records were analyzed.

RESULTS

Of 62 patients who underwent a second hepatectomy, 15 underwent a third hepatectomy, and two underwent a fourth hepatectomy. There was no perioperative mortality. Morbidity was less than 20 percent for the first and second hepatectomies. Overall 5-year survival rate after first hepatectomy was 40 percent. Univariate analysis identified three risk factors confirmed by log-rank test and multivariate Cox regression analysis: serum carcinoembryonic antigen concentrations >5 ng/ml at first hepatectomy (HR = 2.265; CI = 1.140-4.497; P = 0.020), anatomic resection (HR = 2.124; CI = 1.069-4.218; P = 0.031), and tumors > or =3 cm at the second resection (HR = 2.039; CI = 1.013-4.103; P = 0.046).

CONCLUSION

Our study shows that repeat hepatectomy for liver metastases of colorectal carcinoma may be performed with low mortality and morbidity. Preoperative concentration of carcinoembryonic antigen at first hepatectomy, tumor size, and type of anatomic resection are independent prognostic factors.

The simultaneous occurrence of mucinous cystadenomas in liver and pancreas

The occurrence of mucinous cystadenomas localized to the liver and pancreas simultaneously and treated with a single surgical procedure has been described for the first time in this report. A 47-year-old woman attended the outpatient clinic complaining of abdominal pain and the appearance of an abdominal mass. On clinical examination, hepatomegaly was found. An abdominal computed tomography scan showed a large cystic lesion of the left lobe of the liver, thus causing the hepatomegaly. Moreover, the computed tomography scan showed a cystic lesion of the pancreas. Both lesions had thick walls and septa. Magnetic resonance imaging of the liver and pancreas confirmed the presence of septa within the cysts. Surgery was performed owing to the suspected malignancy. It should be emphasized that the patient had preoperatively received prophylactic treatment for hydatosis. A hepatic pericystectomy and enucleation of the pancreatic lesion were performed during the surgery. Pathology showed a mucinous cystadenoma without sign of malignancy. At the 4-year follow-up, no recurrence was found. This case is of interest for several reasons: the unusual double presentation, the treatment, and the follow-up. This case report confirms the common origin of mucinous cystic tumours of liver and pancreas.

Épidémie de leishmaniose cutanée chez des militaires de retour de mission en Guyane

BACKGROUND

An outbreak of cutaneous leishmaniasis occurred among 71 soldiers who had participated in various missions during a 4-month's period in French Guiana. The aims of this study were (i) to describe outbreak and (ii) to determine risk factors of cutaneous leishmaniasis.

METHODS

All patients were hospitalised. Cutaneous lesions were biopsied and cultured for species identification. Individual information was collected by a physician or a nurse, using on a standardised, anonymous chart. Data were processed with EpiInfo 6.04 and SAS.

RESULTS

Mean age of the 71 soldiers was about 25.9 years (19-37 years). Twelve soldiers presented 56 lesions due to Leishmania (Viannia) guyanensis (attack rate = 16.9 for 100). Among 56 lesions, 13 lesions were localized on the trunk, usually an unexposed body area. Logistic regression highlighted military exercises in the forest during a high risk period of leishmaniasis transmission (OR = 11.2; p < 0.01), and the young age (OR = 1.33; p = 0.04). Vector control measures were not statistically significant.

CONCLUSION

Military authorities should restrict deep forest activities during periods of high risk transmission. Vector control measures are essential. Officers should motivate their soldiers and supervise vector control measures. As ecotourism is developing, tourists as well as workers staying in deep forest must be informed of the risk and about vector control measures.
