Hypothesis: Although total gastrectomy (TG) has been generally accepted as the treatment of choice for upper and middle gastric cancers, some issues are still debated. The objective of this retrospective study was to analyze short- and long-term results of TG (radical and palliative) in a series of 400 patients consecutively admitted to our surgical unit., Design: Retrospective cohort study., Setting: Primary and referral hospital care., Patients: Hospital records of 400 patients who consecutively underwent TG between January 1981 and June 2005 were reviewed., Main Outcome Measures: Surgical complications and survival., Results: Three hundred twelve patients underwent radical procedures, and 88 patients underwent palliative procedures. The incidence of postoperative complications was higher among patients who underwent palliative TG (33 of 88 [37.5%]) compared with patients who underwent curative TG (75 of 312 [24.0%]) (P =.01). Mortality was higher among patients who underwent palliative TG (6 of 88 [6.8%]) compared with patients who underwent curative TG (11 of 312 [3.5%]) (P =.18). Five-year survival was 61.8% after curative TG and 12.8% after palliative TG. Ten-year survival was 47.3% after curative TG and 0.0% after palliative TG., Conclusions: This study among 400 consecutive patients who underwent TG at the same surgical unit shows that this surgical procedure in experienced hands can lead to excellent short- and long-term results.

Hypothesis: Anastomotic disruption of the Roux-en-Y esophagojejunostomy after total gastrectomy is an infrequent complication that may lead to severe morbidity and mortality. Consequently, a nasojejunal tube (NJT) is frequently placed when this operation is performed. However, no studies have compared routine vs no placement of an NJT in patients undergoing total gastrectomy for gastric cancer, to our knowledge., Design: Randomized controlled trial to assess the need for routine nasojejunal decompression after total gastrectomy with Roux-en-Y esophagojejunostomy in patients with gastric cancer., Setting: Tertiary care centers., Patients: Two hundred thirty-seven patients undergoing total gastrectomy for gastric cancer were randomly assigned to NJT placement (NJT group) or not (no-NJT group). The patients were monitored for postoperative complications, mortality, and postoperative course., Main Outcome Measures: Incidence of esophagojejunostomy leak., Results: The rates of anastomotic leak were similar in both groups (6.9% and 5.8% for the NJT group and no-NJT group, respectively; P = .71), as were the rates of major postoperative complications (25.9% and 21.5%, respectively; P = .42) and overall postoperative mortality (0.9% and 0.8%, respectively; P = .50). There were no differences between the 2 groups in the mean+/-SD time to passage of flatus (4.6 +/- 1.3 and 4.5 +/- 1.7 days, respectively) or to starting a liquid diet (7.8 +/- 2.6 and 7.7 +/- 1.6 days, respectively), postoperative length of hospital stay (13.5 +/- 7.3 and 13.9 +/- 10.9 days, respectively), postoperative pain, or postoperative abdominal distention., Conclusion: Routine placement of an NJT after Roux-en-Y esophagojejunostomy is unnecessary in elective total gastrectomy for gastric cancer.

Hypothesis: Immediate enteral feeding following major abdominal surgery reduces postoperative complications and mortality when compared with parenteral nutrition., Design: A prospective multicenter randomized trial., Setting: A university hospital department of digestive surgery., Patients and Interventions: Two hundred forty-one malnourished patients undergoing major elective abdominal surgery were randomly assigned to receive, after surgery, either enteral (enteral nutrition group: 119 patients) or parenteral nutrition (total parenteral nutrition group: 122 patients). The patients were monitored for postoperative complications and mortality., Results: The rate of major postoperative complications was similar in the enteral and parenteral groups (enteral nutrition group: 37.8%; total parenteral nutrition group: 39.3%; P was not significant), as were the overall postoperative mortality rates (5.9% and 2.5%, respectively; P was not significant)., Conclusion: The present study failed to demonstrate that enteral feeding following major abdominal surgery reduces postoperative complications and mortality when compared with parenteral nutrition.

Hypothesis: Despite aggressive approaches, locoregional tumor control and survival rates for patients with cancer of the pancreatic head remain disappointing. In the present study, we address whether intraoperative and adjuvant radiotherapy may improve the prognosis for these patients., Design: A retrospective study., Setting: University hospital., Patients: From February 1985 to December 1995, 46 patients with an adenocarcinoma of the pancreatic head underwent pancreatic resection. The last 26 patients also received intraoperative radiotherapy (except 5 patients) and adjuvant external beam radiation therapy., Main Outcome Measures: Demographic data, tumor characteristics, surgical procedures, 5-year survival, and local control of disease were analyzed retrospectively., Results: The morbidity rate was not increased by adjuvant radiation therapy; it was 43% in patients treated with surgery alone and 57% in patients treated with surgery and radiotherapy (P =.1); operative mortality was 8% (n = 2) and 9% (n = 2), respectively (P =.8). Overall 5-year survival and local control were 13% and 48.6%, respectively. The mean +/- SD 5-year survival was 5.5% +/- 5.3% (median, 10.8 months) in the surgery-alone group and 15.7% +/- 8.6% (median, 14.3 months) in the surgery plus radiotherapy group (P =.06); local control at 5 years was 29.8% +/- 16.9% and 58.4% +/- 19.9%, respectively (P<.01). Median metastasis-free survival was 8 and 9 months, respectively (P =.52). Multivariate analysis showed that adjuvant radiotherapy was an independent prognostic factor for survival (P<.01) and local control of the disease (P =.03)., Conclusion: The present study supports the role of radiotherapy combined with pancreatoduodenectomy for treatment of cancer of the pancreatic head because even if the improvement in overall survival is moderate, it is effective in improving the local control of the tumor.

Background: Pancreas-preserving total gastrectomy for gastric cancer has been proposed to remove lymph nodes along the upper border of the pancreas without performing a distal pancreatic resection. However, the original technique includes the ligation of the splenic artery at its origin and thus carries the risk of pancreatic necrosis., Hypothesis: A technique of pancreas-preserving total gastrectomy that includes ligation of the splenic artery approximately 5 cm distally from the root may reduce the risk of postoperative pancreatic necrosis., Design: Case series., Setting: Both primary and referral hospital care., Patients: Hospital records of 228 consecutive patients who, according to a personal technique, underwent D3 pancreas-preserving total gastrectomy for gastric cancer from 1981 to 1997 were reviewed., Main Outcome Measures: Surgical complications, postoperative deaths, and survival., Results: Hospital morbidity and mortality were 33.3% and 3.9%, respectively. No patients experienced pancreatic necrosis. The 5-year survival rate after curative resection was 53.6%: 96.9% for stage IA, 76.3% for stage IB, 63.0% for stage II, 35.6% for stage IIIA, 27.0% for stage IIIB, and 20.3% for stage IV (N3-positive patients) disease., Conclusion: Results of the present study show the efficacy of this method of radical resection for gastric cancer as demonstrated by the low incidence of postoperative complications and high survival rates.

Background: Immunosuppression associated with homologous blood transfusion was first observed in renal allograft transplantation. Clinical effects of transfusion-induced immunosuppression in surgical patients have been debated in the literature for more than a decade with contradictory results., Objective: To investigate whether homologous blood transfusions significantly affect postoperative septic morbidity and mortality in patients undergoing elective surgery for gastric cancer., Design: Case series., Setting: Hospitalized care., Patients: The hospital records of 209 patients who underwent elective surgery for gastric cancer at the Department of Surgery of the Hospital del Mar, Autonomous University of Barcelona in Spain, and at the Department of Surgery of the Catholic University of Rome in Italy from April 1984 to December 1990 were reviewed, and 179 patients were included in the study., Main Outcome Measures: The following variables were entered into univariate and multivariate analyses to identify factors potentially affecting postoperative septic morbidity: demographic data, weight loss, preoperative serum albumin level and lymphocyte count, type and duration of operative procedure, amount and timing of blood transfusion, and stage of disease., Results: Univariate analysis showed that a large quantity of blood transfused (> 1500 mL) and transfusion in the postoperative period (group C) were associated with a worse clinical outcome. Postoperative transfusion was an independent predictor of septic morbidity in multivariate analysis., Conclusions: Despite transfusion-induced immunomodulation, homologous blood transfusion should not be considered a risk factor for postoperative septic morbidity in patients undergoing elective major abdominal surgery. The timing-response relationship between transfusions and septic morbidity in multivariate analysis may be the effect of uncontrolled confounders such as variation of volemia induced by stress response in patients who were developing or had just developed infectious complications.

Objectives: To identify factors that influence mortality in patients who are affected by intra-abdominal infections (IAIs) and to make a comparison among three different scoring systems: the Acute Physiology and Chronic Health Evaluation (APACHE) II score, the sepsis score of Elebute and Stoner, and the Mannheim peritonitis index., Design: Case series., Setting: Both primary and referral hospital care., Patients: The hospital records of 604 patients who consecutively underwent emergency operations for unequivocal IAIs, both spontaneous and postoperative, from 1981 to 1993, were retrospectively reviewed. Patients with IAIs that were related to peritoneal dialysis or infected ascites, those patients who were affected by primary peritonitis from a distant site, and those patients who underwent operations for acute appendicitis or acute cholecystitis without peritoneal contamination were excluded from the study. Univariate and multivariate analyses were used to calculate the prognostic significance of the following variables: age (< or = 70 vs > 70 years); sex; type (spontaneous vs postoperative) and extent (localized vs diffuse) of infection; preoperative serum levels of albumin, cholesterol, and hemoglobin; preoperative total lymphocyte count; amount of intraoperative blood loss; presence of preoperative organ impairment; the APACHE II score; the sepsis score of Elebute and Stoner; and the Mannheim peritonitis index., Main Outcome Measure: Death was the outcome variable that was studied., Results: Multivariate logistic regression analysis showed that the APACHE II score, the Mannheim peritonitis index, hypoalbuminemia, hypocholesterolemia, and preoperative organ impairment were independent predictors of death., Conclusions: Results showed a significant dominance of host-related factors over the type and source of infection on the prognosis of patients with IAIs. Both the APACHE II score and the Mannheim peritonitis index correctly graded IAI severity and were strongly and independently associated with the outcome; however, the latter score has the advantage of being easier to calculate.

Objective: To compare the results of closed treatment (CT) with the results of open treatment (OT) that uses laparostomy and marsupialization of the lesser sac in patients affected by secondary pancreatic infections., Design: Retrospective cohort study., Setting: Both primary and referral hospital care., Patients: Forty-two patients undergoing emergency operations for unequivocal secondary pancreatic infections (infected pancreatic necrosis [n = 26] and pancreatic abscess [n = 14]) were retrospectively divided into two treatment groups on the basis of the operative treatment: conventional CT (n = 24) (1981 through 1986) and OT by laparostomy and marsupialization of the lesser sac (n = 18) (1987 through 1991). The OT and CT groups were homogeneous regarding demographic characteristics, mean APACHE (Acute Physiology and Chronic Health Evaluation) II score (17.1 +/- 6.0 vs 17.9 +/- 7.2, respectively; P value was not significant), and distribution of patients according to the type of pancreatic infection (infected pancreatic necrosis [13 vs 15, respectively] and pancreatic abscess [five vs nine, respectively]). The use of medical supportive care, including total parenteral nutrition and heavy doses of broad-spectrum antibiotics, was similar in both groups., Main Outcome Measures: Surgical complications; recurrent or persistent sepsis; postoperative death., Results: The incidence of major surgical complications was 55.5% and 8.3% in OT and CT groups, respectively (P = .001). In OT and CT groups, signs of recurrent or persistent sepsis were observed in 5.6% vs 41.7% of the patients, respectively (P = .008): 7.7% vs 46.7% in patients with infected pancreatic necrosis (P = .02) and 0% vs 33.3% in patients with pancreatic abscess (P value was not significant). Overall mortality rates were 22.2% and 28.5% in the OT and CT groups, respectively (P value was not significant). The mortality rates due to recurrent or persistent sepsis in the OT and CT groups were 5.5% and 29.1%, respectively (P = .03)., Conclusions: Although the frequency of major surgical complications after OT is significantly higher than that observed after CT, open drainage by means of laparostomy and marsupialization of the lesser sac controls pancreatic infection better, thus reducing mortality rate due to persistent or recurrent sepsis.
