A cross-sectional nationwide survey on esophageal atresia and tracheoesophageal fistula

BACKGROUND

Our study aims at disclosing epidemiology and most relevant clinical features of esophageal atresia (EA) pointing to a model of multicentre collaboration.

METHODS

A detailed questionnaire was sent to all Italian Units of pediatric surgery in order to collect data of patients born with EA between January and December 2012. The results were crosschecked by matching date and place of birth of the patients with those of diagnosis-related group provided by the Italian Ministry of Health (MOH).

RESULTS

A total of 146 questionnaires were returned plus a further 32 patients reported in the MOH database. Basing on a total of 178 patients with EA born in Italy in 2012, the incidence of EA was calculated in 3.33 per 10,000 live births. Antenatal diagnosis was suspected in 29.5% patients. 55.5% showed associated anomalies. The most common type of EA was Gross type C (89%). Postoperative complications occurred in 37% of type C EA and 100% of type A EA. A 9.5% mortality rate was reported.

CONCLUSIONS

This is the first Italian cross-sectional nationwide survey on EA. We can now develop shared guidelines and provide more reliable prognostic expectations for our patients.

Paediatric ulcerative colitis surgery: Italian survey

BACKGROUND AND AIMS

Recent epidemiological studies showed an increase in ulcerative colitis among children, especially in its aggressive form, requiring surgical treatment. Although medical therapeutic strategies are standardized, there is still no consensus regarding indications, timing and kind of surgery. This study aimed to define the surgical management of paediatric ulcerative colitis and describe attitudes to it among paediatric surgeons.

METHODS

This was a retrospective cohort study. All national gastroenterology units were invited to participate. From January 2009 to December 2013, data on paediatric patients diagnosed with ulcerative colitis that required surgery were collected.

RESULTS

Seven units participated in the study. Seventy-one colectomies were performed (77.3% laparoscopically). Main surgical indications were a severe ulcerative colitis attack (33.8%) and no response to medical therapies (56.3%). A three-stage strategy was chosen in 71% of cases. Straight anastomosis was performed in 14% and J-pouch anastomosis in 86% of cases. A reconstructive laparoscopic approach was used in 58% of patients. Ileo-anal anastomosis was performed by the Knight-Griffen technique in 85.4% and by the pull-through technique in 9.1% of patients. Complications after colectomy, after reconstruction and after stoma closure were reported in 12.7, 19.3 and 35% of cases, respectively.

CONCLUSIONS

This study shows that there is general consensus regarding indications for surgery. The ideal surgical technique remains under debate. Laparoscopy is a procedure widely adopted for colectomy but its use in reconstructive surgery remains limited. Longer follow-up must be planned to define the quality of life of these patients.

Abdominal wall defects: a 33-year unicentric experience

AIM

The aim of this paper was to provide the main clinical features, surgical details, and long term outcome of patients with gastroschisis and omphalocele operated on at Giannina Gaslini Institute between 1976 and 2009.

METHODS

All patients who were operated on between 1976 and 2009 for omphalocele or gastroschisis were included. Detailed informations regarding demographics, maternal history, type of delivery, associated anomalies, surgical details, complications, morbidity and mortality were collected.

RESULTS

Sixty-one patients were included. Type of delivery did not interfere with outcome. Although patients with omphalocele had higher incidence of associated anomalies with their obvious impact on survival and quality of life, they showed a quicker recovery from surgery. Mortality rate was around 5%. Long-term outcome was available in 18 of them and proved to be satisfactory in all although almost 70% of them complained some gastrointestinal issues.

CONCLUSION

Gastroschisis and Omphalocele showed improving survival and outcome during the last decades. Caesarean section proved not to confer advantages over vaginal delivery. Associated anomalies have the highest impact on survival being cardiac malformation the most significant risk factors. Although overall outcome is good in the majority of the patients, gastrointestinal and cosmetic issues seem to have a significant impact on quality of life and overall patients' perspectives.

Laparoscopic approach to acute abdomen from the Consensus Development Conference of the Società Italiana di Chirurgia Endoscopica e nuove tecnologie (SICE), Associazione Chirurghi Ospedalieri Italiani (ACOI), Società Italiana di Chirurgia (SIC), Società Italiana di Chirurgia d'Urgenza e del Trauma (SICUT), Società Italiana di Chirurgia nell'Ospedalità Privata (SICOP), and the European Association for Endoscopic Surgery (EAES)

BACKGROUND

In January 2010, the SICE (Italian Society of Endoscopic Surgery), under the auspices of the EAES, decided to revisit the clinical recommendations for the role of laparoscopy in abdominal emergencies in adults, with the primary intent being to update the 2006 EAES indications and supplement the existing guidelines on specific diseases.

METHODS

Other Italian surgical societies were invited into the Consensus to form a panel of 12 expert surgeons. In order to get a multidisciplinary panel, other stakeholders involved in abdominal emergencies were invited along with a patient's association. In November 2010, the panel met in Rome to discuss each chapter according to the Delphi method, producing key statements with a grade of recommendations followed by commentary to explain the rationale and the level of evidence behind the statements. Thereafter, the statements were presented to the Annual Congress of the EAES in June 2011.

RESULTS

A thorough literature review was necessary to assess whether the recommendations issued in 2006 are still current. In many cases new studies allowed us to better clarify some issues (such as for diverticulitis, small bowel obstruction, pancreatitis, hernias, trauma), to confirm the key role of laparoscopy (such as for cholecystitis, gynecological disorders, nonspecific abdominal pain, appendicitis), but occasionally previous strong recommendations have to be challenged after review of recent research (such as for perforated peptic ulcer).

CONCLUSIONS

Every surgeon has to develop his or her own approach, taking into account the clinical situation, her/his proficiency (and the experience of the team) with the various techniques, and the specific organizational setting in which she/he is working. This guideline has been developed bearing in mind that every surgeon could use the data reported to support her/his judgment.

Laparoscopic treatment of deep pelvic endometriosis with rectal involvement

PURPOSE

Our study aimed to evaluate the feasibility and outcome of laparoscopic excision of deep pelvic endometriosis with extensive rectal involvement causing severe symptoms.

METHODS

Ten patients, mean age 32 years (range, 27-43), with deep pelvic endometriosis and rectal wall involvement, requiring surgical resection, were studied since January 2004. Prior to surgery and 6 months postsurgery, patients completed a 100-point rank questionnaire on intensity of intestinal and extraintestinal symptoms. A laparoscopic approach was performed by a team of a gynecologist and colorectal surgeons.

RESULTS

At surgery, complete excision of infiltrating endometriosis was achieved, with 7 low rectal resections, 2 rectosigmoid resections, and 1 proctectomy with coloanal anastomosis. Additional procedures were: ureter resections (n = 2) with one reimplantation in the bladder, left ovariectomies (n = 2), ovarian endometrioma resections (n = 4), and laser ablation of superficial peritoneal lesions (n = 4). In four cases, a laparotomic conversion was needed. Mean follow-up was 27.6 months (range, 18-37). Neither intraoperative nor postoperative serious complications were observed. All the patients experienced significant improvement of intestinal and extraintestinal symptoms.

CONCLUSIONS

Laparoscopic resection of deep pelvic endometriosis with rectal involvement can be successful in improving digestive and gynecologic symptoms; however, this approach is challenging with a high rate of laparotomic conversion.

Urinary tract infection caused by Kluyvera ascorbata in a child: case report and review of the kluyvera infections in children

Kluyvera species are described infrequently in association with clinically significant infections, and infections caused by these gram negative rods are rare in children. The spectrum of disease due to Kluyvera infection in children includes urinary tract infections, enteritis, soft tissue infections, sepsis, central venous catheter infections and peritonitis. The authors report a case of Kluyvera ascorbata urinary tract infection in a 3-month-old female baby, and they review the literature on Kluyvera infections in children.

[Laparoscopic incisional hernia repair: our experience and review of the literature]

Incisional hernia after laparotomy closure continues to be an important postoperative complication. Historically, the best results have been obtained with the open Rives-Stoppa technique. This approach is done by fixing a prosthetic mesh behind the posterior fascia of the rectus muscle. The laparoscopic approach allows similar mesh placement with minimal dissection. In this study, we review the scientific literature and report our experience, describing the clinical outcome of patients who have undergone laparoscopic repair of ventral hernias. After describing the standard technique of laparoscopic insertion of a prosthesis, we reviewed the records of all our patients who underwent such a procedure from March 2004 to January 2006. A laparoscopic approach was attempted in all patients. The patients' demographic characteristics, operative details and outcomes were recorded. Of 55 patients scheduled to undergo laparoscopic incisional herniorrhaphy, conversion to an open procedure was necessary in 2/55 (3.6%). All the remaining 53 patients (31 men and 22 women; mean age 51.8 years) underwent laparoscopic repair of ventral hernias. The mean fascial defect size was 98.3 cm (range: 5-200 cm). In 52/53 patients (98%) a dual mesh was used. 40% of patients (22/53) had multiple wall defects. The mean operative time was 90 minutes (range: 32-190 minutes). The average hospital stay was 2.6 days (range: 1-16 days). 50/53 patients (94.3%) tolerated an oral diet 24 hours after the operation. 49/53 (92.4%) returned to normal working activity within two weeks. The percentage of complications amounted to 13% (7/55), with 5.6% (5/53) minor and 3.7% (2/55) major complications. In one patient it was necessary to remove the mesh 6 months after surgery because of pain. The recurrence rate of 5.6% confirms the permanence of the repair. The follow-up was 12 months for 44/53 patients and 6 months for 9/53 patients. The procedure for incisional hernia repair used in our study may be performed safely with low complication and recurrence rates and should be considered for the majority of incisional hernia repairs requiring a mesh prosthesis.

Sexual rehabilitation with intracavernous PGE1 injections and oral drug administration in diabetic patients non-responder to oral therapy alone

Diabetes is an important risk factor in erectile dysfunction (ED), acting via several mechanisms. We assessed the efficacy of intracavernous injections (ICI) rehabilitation and oral systematic therapy in diabetic patients, as well as the response of controls to oral therapy ‘on demand’.

Materials and Methods

Sixteen diabetic patients with ED were treated with vasoactive drugs orally when needed, without satisfactory erections. The patients underwent then ICI rehabilitation with PGE1 20 mcg twice weekly for 4 weeks, followed by the administration of oral drugs twice weekly for 4 weeks. Before and after rehabilitation, the patients completed a detailed anamnestic protocol to study their libido (always present); they answered questions Q3 and Q4 of the IIEF questionnaire. During ICI, a study with dynamic echocolordoppler (ECCD) was carried out. All patients had Type 2 diabetes: 10 were treated with oral antidiabetics, 4 were treated with insulin, and in the other 2 patients, treated with insulin, a sensitive neuropathy of the lower limbs was diagnosed. Fourteen patients were treated with antihypertensive drugs.

Results

Before rehabilitation, the mean responses to questions 3 and 4 of the IIEF (International Index of Erectile Function) questionnaire were 1.6 and 1.5 respectively; after rehabilitation, the mean responses were 2.68 and 2.5, respectively. The ECCD test showed an arterial component in 4 cases and a high end-diastolic velocity (EDV) in 14 cases. Four patients (25%), 2 of which had neuropathy, and 2 were in advanced age, did not respond to PGE1 or to oral therapy, 4 patients (25%) (2 treated with insulin and 2 by oral therapy) responded to ICI but not to oral therapy, while 8 patients (50%) showed a good response to both injectable and oral therapy, with good Q3 and Q4 scores.

Conclusions

Good endothelial function appears to be essential for the maintenance of acceptable erectile function. Diabetes has a negative effect on this function, as does hypoxia and low perfusion. Based on the principle that a good erection improves endothelial function, we tried to determine if oral systematic and intracavernous rehabilitation would improve erectile function in diabetic patients. The results indicate that diabetes interferes with erectile function, compromising the effects of the vasoactive drugs. However, integrated systematic rehabilitation appears to allow a good erectile response to both intracavernous and oral therapy in a large number of cases. Therefore, we support this kind of rehabilitative protocol in the treatment of ED in diabetic patients.

Impact of age on postoperative outcomes in 1118 gastric cancer patients undergoing surgical treatment

BACKGROUND

The purpose of the study was to evaluate the impact of age on outcomes in gastric cancer surgery.

METHODS

Patients on the hospital database who underwent gastric resection for gastric cancer during the period 1990-2005 (n = 1118) were divided into two groups: group A, patients 75 years or older (n = 249), and group B, those younger than 75 years (n = 869).

RESULTS

Overall preoperative complications were diagnosed in 92 (37%) patients of group A, compared with 147 (17%) in group B (P = 0.002). Fifty-five percent of patients underwent resection with D2 or more lymph node dissection (37% [n = 93] in group A, and 60% [n = 521] in group B; P = 0.003). Postoperative overall morbidity was higher in the elderly group (29% in group A versus 23% in group B), but the difference between the two groups was not significant (P = NS). Overall postoperative surgical complications were recorded in 201 (18%) patients; 49 (20%) in the elderly cohort, compared with 147 (17%) in the younger group (P = NS). The postoperative mortality rate was 3% (n = 7) in the elderly group, compared with 3% (n = 26) in the younger cohort (P = NS). Multivariate Cox analysis showed that age was not an independent risk factor for postoperative morbidity and mortality. Overall 5-year survival was 47% in group A and 54% in group B (P = NS).

CONCLUSION

Due to improved perioperative management, resection of gastric carcinoma is the treatment of choice in elderly patients. Although comorbidities were more frequent among the elderly patients, postoperative morbidity and mortality, even after extensive resections, was low. Survival rates were comparable to those in the younger patients.

Multivariate Analysis of Factors Affecting Patient and Graft Survival After Renal Transplant

AIM

To evaluate factors affecting patient and kidney survival after renal transplant.

PATIENT AND METHODS

Among 361 patients undergoing renal transplant: 52% (n = 189) were simultaneous with pancreas transplant (SPKT group) and 48% (n = 172), a kidney transplant alone (KT group). Out of 361 patients, 75% (n = 270) were diabetics. The patients were 220 (61%) men and 141 (39%) women of mean age 41 +/- 9 years. The mean time of dialysis was 42 +/- 21 months (range 0 to 126), and the mean duration of diabetes 24 +/- 7 years (range 5 to 51). A Cox regression analysis was done.

RESULTS

The multivariate analysis revealed that in the final model diabetes and donor age were significant predictors of kidney graft survival; moreover, diabetes and recipient age were predictors of patient survival. Overall patient survival was significantly greater among nondiabetic patients (P = .002) or in diabetic patients who received SPKT, when compared with diabetics in whom only the kidney was transplanted (P = .001).

CONCLUSIONS

Diabetes and donor age were independent prognostic factors affecting kidney graft survival after renal transplant, and recipient age and diabetes were prognostic factors affecting patient survival. Combined pancreas and kidney transplantation should be offered to patients with end-stage diabetic nephropathy.

[Minimally invasive esophagectomy for adenocarcinoma of the lower esophagus and the gastroesophageal junction]

BACKGROUND

Adenocarcinoma of lower esophagus and GEJ shows worldwide an increasing incidence. The optimal approach to resection is still controversial. One of the major disadvantages of radical esophagectomy with extensive lymphadenectomy with open technique is its high rate of morbidity and mortality. Recent advances in minimally invasive surgical technology have allowed surgeons to apply laparoscopy and thoracoscopy to perform esophagectomy.

PATIENT AND METHODS

In the video we report the case of a 79 years old man with Siewert I adenocarcinoma of GEJ, who was submitted to a 3-stage minimally invasive esophagectomy by laparoscopy, right thoracoscopy and cervicotomy. Preoperative endoscopic ultrasound and CT scan showed a marked thickening of the wall of the distal esophagus, with extension proximal to the mediastinal pleura and the anterior surface of the aorta, but still showing features of resectability. Four ports were used for the abdominal approach. A complete mobilization of the stomach preserving the right gastroepiploic arcade was achieved. The patient was then turned to the left lateral decubitus position proned to 30 degrees. Three ports were needed for right thoracoscopy. Mobilization of the thoracic esophagus was carried out from the diaphragm to the thoracic inlet. After extraction of the specimen through a small abdominal incision, the stomach was pulled up to the neck and esophagogastric anastomosis with the Orringer technique was constructed through a left cervicotomy. Pathology showed pT3 pN1 G3 adenocarcinoma.

CONCLUSIONS

The minimally invasive approach to adenocarcinoma of the lower esophagus, in center with expertise in minimally invasive surgical technique, is feasible and safe.

[Prognostic factors of gastric neoplasms: experience with 1,074 cases undergoing surgical treatment at a single center]

AIM

The aim of our study was to identify clinicopathological predictors of survival among patients undergoing potentially curative resections for gastric carcinoma.

PATIENTS AND METHODS

From January 1987-March 2004, 1074 patients have been submitted to curative gastric resection for gastric cancer (647 males and 427 females, mean age, 65 +/- 12, min 22, max 92). The surgical procedure consisted of 289 (27%) total and 785 (63%) subtotal gastrectomies. The extent of lymph node dissection was limited D1 (n = 376, 35%) or extended D2 (n = 578, 54%) and D3 (n = 12, 1%); no lymphadenectomy was performed in 108 (10%) cases. The pathological nodal status has been defined based on the number of involved lymph nodes (N1: 1 to 6 positive nodes; N2: 7 to 15 positive nodes; N3: more than 15 positive nodes). The distribution of N stage was: N0 = 278 (26%), N1 = 344 (32%); N2 = 215 (20%); N3 = 129 (12%). Univariate analyses were performed for gender, age, pT stage, pN stage, tumor site, tumor size, and extent of lymphadenectomy. Significant factors were then entered into a Cox regression analysis.

RESULTS

The median number of examined lymph nodes was 17 (mean, 18). Overall, 688 (64%) of patients had lymph node metastases. Of these patients, the median number of involved nodes was 2 (mean, 6). In the univariate analysis age, pT stage, pN stage, tumor size, and extent of lymphadenectomy were found to be significant factors. In the multivariate analysis T stage, N stage, and extent of lymphadenectomy were all independent predictors of survival. The median and mean survival time were 69 and 87 months, respectively. Overall survival was 80%, 51% and 40% at 1, 5, and 10 years, respectively.

CONCLUSIONS

T stage, N stage, and extent of lymphadenectomy were all independent predictors of survival in patients submitted to curative gastric resections.

[Gastrectomy and laparoscopic lymphadenectomy for carcinoma: preliminary experience with 59 cases]

BACKGROUND

Laparoscopic surgery has been used in the treatment of gastric cancer with low mortality and morbidity and improvement in patient's quality of life.

AIM

To evaluate the results of laparoscopic gastric resection.

METHODS

A retrospective review of 59 patients after laparoscopic surgery for gastric cancer was performed. The patients were 31 males and 28 females with a mean age of 67 (+/- 11) years (min 39, max 90).

RESULTS

Tumor stage was IA in 15 patients, IB in 10, II in 9, IIIA in 6, IIIB in 9, and IV in 10. In 15 cases the tumor was an early gastric cancer. The mean number of dissected lymph nodes was 29 +/-10. Conversion rate was 16%. Morbidity rate was 37%. The median length of hospital stay was 10 days. Operative mortality was 3%. The mean time of follow-up was 23 months. Two-year survival was 75%.

CONCLUSIONS

Laparoscopic radical total or subtotal gastrectomy with extended lymphadenectomy for gastric cancer is a feasible, safe, and oncologically effective procedure.

Complications After Percutaneous Transaxillary Implantation of a Catheter for Intraarterial Chemotherapy of Liver Tumors:Clinical Relevance and Management in 204 Patients

OBJECTIVE

The purposes of the study were to evaluate the complications of patients who underwent percutaneous transaxillary implantation of a permanent catheter-port system for intraarterial hepatic chemotherapy and determine their clinical relevance and specific management. SUBJECTS AND METHODS. Catheter-port systems were placed in 204 patients with liver tumors (86.7% from colorectal metastases). Under sonographic and fluoroscopic guidance, a 5.8-French catheter was placed in the hepatic artery and connected to a subcutaneous reservoir after embolization of the gastroduodenal and right gastric arteries. Floxuridine plus dexamethasone and systemic low-dose heparin were administered. During the follow-up period, complications were classified as clinically not significant (type 1), clinically significant not requiring interruption of intrahepatic chemotherapy (type 2), clinically significant needing temporary suppression of intrahepatic chemotherapy (type 3), and clinically significant causing permanent suppression of intrahepatic chemotherapy (type 4).

RESULTS

No complications occurred during the implantation procedures. The mean number of intrahepatic chemotherapy cycles was 8.1. The mean follow-up period was 270 days. Primary and secondary patency rates of the system were 71.6% and 91.2%, respectively. Temporary suppression of intrahepatic chemotherapy was necessary in 19.6% of the patients and definitive suppression, in 8.8%. Hepatic artery thrombosis, not recanalized by local thrombolysis, was the main cause of permanent intrahepatic chemotherapy interruption (4.4%). Catheter occlusions and cerebral complications were not observed. In 91.2% of the patients, intrahepatic chemotherapy could be completed.

CONCLUSION

Percutaneous implantation of a removable and reimplantable catheter-port system for intrahepatic chemotherapy can be a safe procedure to treat unresectable liver metastases from colorectal cancer. Technical and pharmacologic complications with variable clinical relevance occurred, and various specific management strategies were necessary to reduce their incidence.

Hemorrhage from a right hepatic artery pseudoaneurysm: endovascular treatment with a coronary stent-graft

PURPOSE

To report a novel case demonstrating the successful endovascular treatment of a right hepatic artery pseudoaneurysm using a balloon-expandable coronary stent-graft.

CASE REPORT

A 60-year-old woman underwent surgical treatment for a Klatskin tumor, but her postoperative course was complicated by serious blood loss. An emergent celiac angiogram through a right transfemoral approach demonstrated a small iatrogenic pseudoaneurysm in the proximal right hepatic artery. A 7-F guiding catheter was positioned at the origin of the celiac trunk, and a Jostent coronary stent-graft mounted on a 2.7-F, 4-mm x 30-mm balloon catheter was successfully placed across the aneurysm neck. The final angiogram demonstrated total exclusion of the pseudoaneurysm with preservation of the arterial lumen. The hemodynamic condition of the patient became stable. At 12-month follow-up, duplex scanning confirmed regular right hepatic artery patency and absence of thrombotic tissue or signs of infection around the stent-graft.

CONCLUSION

For hepatic artery pseudoaneurysms, endovascular repair using small covered stents may be a viable alternative to transcatheter embolization. The use of coronary instruments facilitates treatment of vascular lesions in small caliber visceral vessels.

[The Pap test in HIV-positive women]

The aim of this work was to estimate the frequency of abnormal Papanicolau (Pap) smears in a group of HIV-infected women undergoing cervical screening. We re-examined 162 Pap smears from 118 patients infected with HIV. The patients were aged 23-55 years. A total of 108 smears (66.6%) from 80 patients were negative; 14 smears (8.6%) from 14 patients showed inflammation; 3 smears (1.8%) from 3 patients had atypical squamous cells of undetermined significance (ASCUS); 20 smears (13.5%) from 16 patients were abnormal for human papillomavirus (HPV); 13 smears (8.0%) from 9 patients revealed low-grade, squamous intraepithelial lesions; 10 smears (6.2%) from 7 patients were SIL-HG; the diagnosis of carcinoma was made in 3 cases (1.8%) and 2 smears from 2 patients were unsatisfactory. HIV-infected women have an increased rate of abnormal Pap smears for both HPV infections and cervical dysplasia. These results confirm the validity of cervical screening by Pap test.

[Laparoscopic versus conventional surgery in the treatment of colorectal diseases]

The aim of the study was to compare the results obtained with laparoscopic (LPS) and laparotomic (LPT) colorectal resection after our initial experience with the laparoscopic technique. Fifty-six patients were submitted to colorectal resection, 26 with the LPS and 30 with the LPT technique. Eighteen patients out of 26 in the LPS group and 22/30 in the LPT group had malignancies. All resections were performed with a curative intent. The mean operating time was 220 min in the LPS group and 208 min in the LPT group. Mean blood loss was 287 ml and 312 ml, respectively (blood transfusions were needed in 1/26 and in 7/30 patients). The rates of major complications were 9.5% and 5.7%, respectively. There was no mortality. The conversion rate for the LPS group was 19.2%. In the cancer patients, no significant difference was observed between the two groups as regards postoperative staging. The mean length of specimens and the mean distance of the tumours from the resection margins were adequate. The mean number of lymph nodes harvested was 11.8 in the LPS group as against 18.5 in the LPT group. No early recurrences were observed. Resumption of gastrointestinal function was faster in the LPS patients who underwent the surgical procedure under general anaesthesia associated with epidural anaesthesia/postoperative analgesia. In conclusion, these preliminary results indicate that laparoscopic colorectal surgery is feasible and that the resections in cancer patients appear to be oncologically adequate. Long-term follow-up is needed for reliable assessment of oncological outcomes.

[Intraoperative radiotherapy as adjuvant treatment for resection of carcinoma of the pancreas]

Local recurrence is the most frequent site of failure after resection for pancreatic cancer. We reported our experience in term of tolerance, local control and survival obtained by the association of resection and intraoperative radiation therapy (IORT). Between January 1985 and July 1996 152 resection for pancreatic cancer were performed at the authors' institution. For 77 patients, IORT was added to resection (group 1), whereas the other 75 patients underwent resection alone (group 2), because of either the unavailability of the linear accelerator or the patient's refusal. In group 1, radiation doses from 12.5 to 20 Gy, with electron beam energies between 6 and 12 MeV, were delivered. Extension of the disease, percentage of radical resection and postoperative chemotherapy were similar in the two groups of patients. Operative mortality and overall early postoperative complications were respectively 1.3% and 31.2% in group 1 and 4% and 32% in group 2. The median survival was 17 months in group 1 and 15 months in group 2 and the median disease free survival was 12 months in group 1 and 8 months in group 2. A local recurrence was detected in 31% of patients in group 1 and in 49.3% of patients in group 2 (p < 0.1). The results suggest a better local control in patients with pancreatic cancer undergoing adjuvant IORT.
