Gastrostomy or jejunostomy allow a safe and effective long-term enteral nutritional support. In patients with stenosis of the upper gastrointestinal tract the percutaneous endoscopic route is frequently not feasible. In these cases a laparoscopic approach is proposed. In 18 patients (n = 18) mostly with recurrent tumors of the upper gastrointestinal tract a laparoscopic catheter was placed into the jejunum without complications. Enteral feeding was started on the first day after catheter placement. One patient experienced a cathetersite infection. We describe a modified technique of laparoscopic jejunostomy the placement which is easy, effective and less invasive.

The repair of multiple recurrences of inguinal hernias remains a surgical challenge. In 38 patients with a problematic recurrent inguinal hernia we implanted a polypropylene mesh (Prolene) in order to reinforce the transversalis fascia and to repair the inguinal hernia. 20 of these were medial and 14 lateral hernias; 4 patients had a combination of both types. All patients were prospectively included into this study and were seen in median follow-up periods of 3 and 6 months, as well as 4 and 9 years. As early complications hematoma of the wound (n = 3), scrotal edema (n = 1), temporary pain at the wound site (n = 12) and paresthesia (n = 13) occurred. Two patients (n = 2) developed a femoral hernia and one patient suffered from a persisting nerve injury of the ilioinguinal nerve. Due to the low complication and recurrency rate the tension free repair with polypropylene mesh is a effective method for treatment of problematic recurrent hernias.

This is a case report of a female patient who during a routine follow-up after a gastrectomy showed a tumor of the ileo-cecal valve, which--according to all radiologic diagnostic procedures--was highly suspected to be a malignant tumor. However, the histologic diagnosis was benign lipoma. The incidence and the characteristics of gastrointestinal lipomas in the actual literature will be reviewed.

Objective: To determine if early postoperative feeding of patients with upper gastrointestinal malignancy, using an enteral diet supplemented with arginine, dietary nucleotides, and omega-3 fatty acids (IMPACT, Sandoz Nutrition, Bern, Switzerland) results in an improved clinical outcome, i.e., reduced infectious and wound complications and decreased treatment costs when compared with an isocaloric, isonitrogenous control diet., Design: A prospective, randomized, placebo-controlled, double-blind, multicenter trial of the clinical outcome and a retrospective cost-comparison analysis., Setting: Surgical intensive care units in three different German university hospitals., Patients: Of 164 patients enrolled in the study, 154 patients were eligible for analysis. They were admitted to the intensive care unit after upper gastrointestinal surgery for cancer and they received an enteral diet via needle catheter jejunostomy. Infectious complications were defined as sepsis or systemic inflammatory response syndrome, pneumonia, urinary tract infection, central venous catheter sepsis, wound infection, and anastomotic leakage. The complication events were prospectively divided into two groups: early (postoperative days 1 to 5) and late (after the fifth postoperative day) postoperative complications. The treatment costs of each complication were analyzed and compared in both groups., Interventions: Patients were randomized to receive either the immunonutritional diet (n = 77) or an isocaloric and isonitrogenous placebo diet (n = 77). Enteral feeding was initiated 12 to 24 hrs after surgery, starting with 20 mL/hr and advanced to a target volume of 80 mL/hr by postoperative day 5., Measurements and Main Results: Clinical examination and adverse gastrointestinal symptoms were recorded on a daily basis. Both groups tolerated early enteral feeding well, and the rate of tube feeding-related complications was low. Postoperative complications occurred in 17 patients in the immunonutrition group vs. 24 patients in the control group (NS). Further, in the early phase (postoperative day 1 to 5), complications occurred to a similar extent in both groups (12 patients in the immunonutritional group vs. 11 patients in the control group). However, in the late phase (after postoperative day 5), considerably fewer patients in the experimental diet group experienced complications compared with the control group (5 vs. 13, p < .05). In addition, the frequency rate of complicating events were recorded in each group. In the experimental diet group, a total of 22 complicating events were recorded vs. a total of 32 events in the placebo diet group (NS). However, the occurrence of late complicating events, i.e., complicating events after the fifth postoperative day, was significantly reduced in the immunonutrition group when compared with the control group (8 vs. 17 events, p < .05). The total costs for the treatment of the complications were 83,563 German marks in the experimental diet group vs. 122,430 German marks in the control group, resulting in a cost-reduction of 38,867 German marks. (At the end of December 1995, the conversion rate from German marks to U.S. dollars was 1.4365 German marks to $1.00.), Conclusions: Early enteral feeding with an arginine, dietary nucleotides, and omega-3 fatty acids supplemented diet, as well as an isonitrogenous, isocaloric control diet (placebo) were well tolerated in patients who underwent upper gastrointestinal surgery. In patients who received the supplemented diet, a significant reduction in the frequency rate of late postoperative infectious and wound complications was observed. Thereby, the treatment costs were substantially reduced in the immunonutrition group as compared with the control group.

In this study of 154 patients with major abdominal cancer surgery, 41 postoperative complications occurred and caused additional total costs of DM 205.993,-, DM 5.024,- per case, respectively, where the special personnel costs were not accounted for. There was a significant difference between single and multiple complications as well as for early and late complication costs. Economic analyses are necessary to determine budgets of medical departments with extended and cost-intensive treatment, such as cancer surgery, to maintain optimal care for the patients.

In this economic evaluation we compared the costs of a new therapeutic system (two-chamber bag) in total parenteral nutrition (TPN) with the comparative standard therapeutic systems (multiple-bottle system in intensive care patients followed by a combination solution (glass bottles) on the ward). In the model, standard treatment algorithms of a 10-day course TPN for patients after major gastric surgery were specified for both application systems, the two-chamber bag and the comparative system. Based on the standard treatment pattern, the resource utilisation (manpower services, medical needs, material) was assessed. In a base case analysis the types and amounts of resources were valued using salaries, prices and tariffs to assess the costs. The costs per day and per case of the therapeutic systems were compared. Sensitivity analyses were carried out to validate the cost-estimates. The total costs per patient of the two-chamber bag amounted to DM 2324.41, which was substantially less than the DM 2728.99 cost of the comparative system. The average daily costs for the two-chamber bag system were 12% to 23% lower than for the comparative system. The results were shown to be valid for the whole range of tested parameters. This model makes it possible to obtain an economic evaluation of various therapeutic modalities without undertaking a prospective randomized study with the attendant high time and cost requirements.

Objective: To evaluate the effect of early postoperative feeding with a nutritionally complete enteral diet supplemented with the nutrients arginine, ribonucleic acid (RNA), and omega-3 fatty acids on the immune function in patients undergoing surgery for upper gastrointestinal (GI) malignancies., Design: Prospective, randomized, placebo-controlled, double-blind study., Setting: Surgical intensive care unit (ICU) in a German university hospital., Patients: Forty-two consecutive patients receiving an enteral diet via needle catheter jejunostomy after GI surgery for cancer., Interventions: Patients were randomized to receive either the arginine, RNA, and omega-3 fatty acids supplemented diet or an isocaloric and isonitrogenous placebo diet. Early enteral nutrition was started on postoperative day 1 in the surgical ICU with 20 mL/hr and progressed to the optimal goal of 80 mL/hr by postoperative day 5., Measurements and Main Results: Clinical examination and adverse GI symptoms were recorded on a daily basis. Body weight was determined twice weekly. Immunoglobulin concentrations were determined by laser nephelometry. Interferon-gamma concentrations were measured with a modified enzyme-linked immunosorbent assay method. Fluorescence-activated cell scan flow cytometry was performed to analyze B cells, T lymphocytes and their subsets. Clinical patient characteristics and mean caloric intake were similar between the two groups and both formulas were well tolerated. The number of T lymphocytes and their subsets, helper T cells (CD4) and activated T cells (CD3, HLA-DR), were significantly higher in the supplemented diet group on postoperative days 10 and 16 (p < .05). Mean interferon-gamma concentration after phytohemagglutinin stimulation was higher in the supplemented diet group on postoperative day 16. In the supplemented diet group, mean immunoglobulin M concentrations were significantly higher on postoperative day 10 and mean immunoglobulin G concentrations were higher on postoperative day 16 (p < .05) compared with the results in the placebo group. B-lymphocyte indices were significantly higher in the supplemented vs. the placebo diet group on postoperative days 7 and 10 (p < .05)., Conclusions: Supplementation of enteral diet with arginine, RNA, and omega-3 fatty acids in the early postoperative time period improves postoperative immunologic responses and helps to overcome more rapidly the immunologic depression after surgical trauma.

Objective: To find out whether an enteral diet supplemented with arginine, RNA, and omega-3 fatty acids modulated the production of interleukin-1 (IL-1), interleukin-2 (IL-2), IL-2 receptor, interleukin-6 (IL-6), and tumour necrosis factor alpha (TNF-alpha) after operations for upper gastrointestinal cancer., Design: Prospective double blind clinical study., Setting: University hospital, Germany., Subjects: 42 patients randomised into two groups (n = 21 each), one of which was given an isocaloric and isonitrogenous placebo diet and one of which was fed the same diet supplemented with arginine, RNA, and omega-3 fatty acids., Interventions: The cytokines were measured before operation and on postoperative days 1, 3, 7, 10, and 16., Main Outcome Measures: Comparison of concentrations of cytokines in the two groups., Results: Among those receiving the placebo diet (after spontaneous stimulation) IL-6 concentrations were significantly higher on days 3 and 7 (p < 0.05) and TNF-alpha concentrations on day 7. In contrast (after stimulation with phytohaemagglutinin) mean concentrations of IL-2 receptor were significantly higher on days 3 and 7, and of IL-1 beta and IL-2 on day 16 (p < 0.05) in the group receiving the supplemented diet., Conclusion: Supplementation of an enteral diet with arginine, RNA and omega-3 fatty acids can modulate the acute phase reaction as indicated by the reduction in concentrations of TNF-alpha and IL-6 in the group fed the supplemented diet. Patients receiving the supplemented diet also showed accelerated recovery in the concentrations of IL-1 beta and IL-2 receptor.

The laparoscopic cholecystectomy of gall bladder carcinoma may have unfortunate consequences because of tumor cell dissemination. In this case report a female patient is presented, where histologically a gallbladder carcinoma was surprisingly diagnosed after laparoscopic cholecystectomy because of symptomatic cholecystectomy. 2 weeks after the first operation tumor cell clusters were found in the laparoscopy tracts.

Background: Gastrointestinal side effects, particularly diarrhea, are still the main reasons for discontinuation of enteral nutrition. Although the causes of diarrhea are diverse, the enteral nutrition solution is frequently suspected of playing a leading role in causing diarrhea., Methods: Our randomized, prospective, double-blind trial with 100 patients assessed the effects of feeding a standard diet (Nutrodrip Standard) vs the same diet supplemented with 20 g of soluble fiber, containing partially hydrolyzed guar gum (Sunfiber), per 1000 mL. Thirty patients received total enteral nutrition postoperatively, and 70 patients received enteral supplementation., Results: The patients receiving total enteral nutrition with soluble fiber had decreased diarrhea but increased flatulence. In none of these patients did enteral feeding have to be discontinued because of gastrointestinal side effects, whereas in four patients who were on a standard diet, enteral feeding had to be interrupted because of diarrhea (p < .05). Similar observations were made in patients receiving enteral supplementation. In both groups, the incidence of diarrhea decreased significantly with the soluble fiber diet compared with the standard diet (6 vs 15, p < .05)., Conclusions: Enteral feeding with a formula supplemented with partially hydrolyzed guar gum reduces the incidence of diarrhea in patients receiving total enteral nutrition as well as in those receiving enteral supplementation, regardless of the cause of diarrhea. The increased hydrogen production and the significantly higher rate of flatulence are likely to result from fermentation of the soluble fiber in the colon, with concomitant production of short-chain fatty acids, which leads to increased absorption of short-chain fatty acids, sodium, and water by the colonocytes. This effect, together with the observed cholecystokinin-mediated decrease in colonic transit time with partially hydrolyzed guar gum, may explain the reduction in the incidence of diarrhea in this study.
