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.

Frey procedure in patients with chronic pancreatitis: short and long-term outcome from a prospective study.

BACKGROUND: The aim of this prospective study was to determine the short- and long-term results of the Frey procedure in the treatment of chronic pancreatitis. METHODS: From September 2000 to November 2009, 44 consecutive patients underwent the Frey procedure. Patients were included in the study before surgery and followed prospectively with assessment of pain relief, weight gain and exocrine/endocrine insufficiency. Twenty-one patients (47.7%) were followed for more than 5 years. RESULTS: This study included 40 men (91 %) and four women (9 %) (mean age: 49 years) with a mean follow-up of 51.5 months. The primary etiology of chronic pancreatitis was chronic alcohol abuse in 38 patients (86.4 %). The major indication for surgery was disabling pain (95.5 %). There was no postoperative mortality. Postoperative morbidity occurred in 15 patients (34.1 %), with specific surgical complications in 11 patients (25 %). The percentage of pain-free patients after surgery was 68.3 %. Eight patients (18.1 %) and seven patients (16 %) developed diabetes de novo and exocrine insufficiency, respectively. The Body Mass Index showed statistically significant improvement during follow-up. Similar beneficial results concerning pain relief and weight gain persisted after the initial 5-year follow-up. CONCLUSIONS: The Frey procedure is an appropriate, safe and effective technique for management of patients with chronic pancreatitis in the absence of neoplasia, based on long-term follow-up.

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.

Management of a stenotic pancreatico-digestive tract anastomosis following pancreatoduodenectomy.

Early postoperative complications of pancreatico-digestive anastomosis following pancreatoduodenectomy are pancreatic fistula and pancreatitis affecting the pancreatic tail. Stenosis of the anastomosis is a later complication. Symptomatic and painful presentations are difficult to treat, and the optimal treatment is not currently defined. The aim of this work was to retrospectively report two cases of pancreaticogastrostomy stenosis. In both patients, the complication was diagnosed, with pancreatitis that developed following pancreatoduodenectomy. These patients were treated surgically, by fashioning a new anastomosis. Pancreaticogastrostomy has been viewed as a simpler and more secure reconstruction technique, with a lower occurrence rate of pancreatic fistula, than that of pancreaticojejunostomy. One complication of this surgery, however, is stenosis of the anastomosis. Following pancreatoduodenectomy, stenosis of the pancreaticogastrostomy may not occur until many years later. In a significant percentage of patients it is without clinical signs. It may be discovered after systematic explorations of patients following pancreaticogastrostomy or pancreaticojejunostomy. There is no study regarding the optimal treatment of postoperative stenosis of a pancreatico-gastric anastomosis. We believe that the optimal treatment is surgical. The intervention involves resection of the stenosis, and the formation of a new anastomosis.

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.
