Pouch versus esophagojejunostomy after total gastrectomy: a randomized clinical trial

Laparoscopic Hunt-Lawrence Jejunal Pouch for Reconstruction After Total Gastrectomy for Gastric Cancer

Background: There are several reconstruction options described in the literature after total gastrectomy for gastric cancer. The most common laparoscopic jejunal pouch technique involves evisceration of the small bowel and extracorporeal pouch formation. Methods: We describe a completely intracorporeal technique for the Hunt-Lawrence J-pouch Roux-en-Y reconstruction. After gastrectomy and formation of the Roux limb, we create the esophagojejunal anastomosis using an end-to-end anastomosis (EEA) stapler threaded 6-7 cm into the Roux limb to leave a tail of jejunum for the pouch. Next we form the jejunal pouch with a linear stapler and close the common enterotomy with suture or stapler. Conclusion: Our technique offers a streamlined and efficient approach to the Hunt-Lawrence reconstruction and can be effectively performed both laparoscopically and robotically.

Nutritional Results of Roux-en-Y Pouch Reconstruction After Total Gastrectomy for Gastric Cancer

Objective:

The aim of the present study was to describe the nutritional advantage of pouch reconstruction.

Summary of background data:

Roux-en-Y (RY) pouch reconstruction might improve patients' quality of life compared with RY reconstruction without a pouch after total gastrectomy for gastric cancer.

Methods:

Clinical records were retrospectively reviewed in 9 and 30 patients with gastric cancer for stages I to III diseases in the pouch and RY groups, respectively, and perioperative and nutritional results were studied. Nutritional results were studied for hemoglobin, serum albumin, total lymphocyte count, and prognostic nutritional index for 5 years postoperatively.

Results:

Intraoperative blood loss did not differ between 2 groups, and operative time in the pouch group was prolonged compared with the RY group. All parameters we studied for nutritional results did not differ between the pouch and RY groups in patients with stages I to III diseases. When nutritional results were investigated in patients with stage I diseases, the total lymphocyte count at 2 years and prognostic nutritional index at 2 and 3 years postoperatively were greater in the pouch group than RY group, but the increase was not obvious at 4 to 5 years after the operation, and serum albumin and hemoglobin did not differ between 2 groups.

Conclusions:

These results indicate that the nutritional advantage of pouch reconstruction is very limited after total gastrectomy because the nutritional benefits of pouch reconstruction were observed in 2 of 4 parameters in patients with stage I at 2 and 3 years postoperatively.

Long-Term Consequences of Total Gastrectomy: Quality of Life, Nutritional Status, Bacterial Overgrowth and Adaptive Changes in Esophagojejunostomic Mucosa

OBJECTIVES

The aim of the study was to evaluate long-term quality of life and adaptive changes in the mucosa of the proximal section of the small intestine used for esophagojejunostomy reconstruction in stomach cancer patients after total gastrectomy.

MATERIAL AND METHODS

Thirty-one patients who had undergone stomach cancer-related total gastrectomy were included in the study, which spanned a period of 48 to 127 months (79.6 months on the average) after the surgery. The analysis included: a) evaluation of selected biochemical parameters; b) microbiological evaluation of esophagojejunostomic area; c) evaluation of adaptive changes in esophagojejunostomic mucosa using light and electron microscopy; d) quality of life evaluation with a Troidl questionnaire.

RESULTS

Quality of life was subjectively rated as good or very good by almost all subjects. The analyzed biochemical parameters were within the range of normal values in all the subjects with the exception of mild abnormalities in alkaline phosphatase and vitamin B12 levels in some patients. Microbiological examination of mucosal specimens from below the esophagojejunostomy revealed significant bacterial flora overgrowth in all the patients, with streptococci being the most abundant species. Light and electron microscopy examination of the epithelium confirmed it was normal and characteristic of a healthy small intestine.

CONCLUSIONS

Long-term quality of life in patients after complete stomach resection is considered good or very good, irrespective of the reconstruction method used, and the esophagojejunostomic mucosa of the reconstructed area is normal and typical for a healthy small intestine.

Using Quality of Life Scales with Nutritional Relevance after Gastrectomy: a Challenge for Providing Personalized Treatment

Purpose

This study evaluated the changes in nutritional status based on quality of life (QoL) item-level analysis to determine whether individual QoL responses might facilitate personal clinical impact.

Materials and Methods

This study retrospectively evaluated QoL data obtained by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) and Quality of Life Questionnaire-Stomach (QLQ-STO22) as well as metabolic-nutritional data obtained by bioelectrical impedance analysis and blood tests. Patients were assessed preoperatively and at the 5-year follow-up. QoL was analyzed at the level of the constituent items. The patients were categorized into vulnerable and non-vulnerable QoL groups for each scale based on their responses to the QoL items and changes in the metabolic-nutritional indices were compared.

Results

Multiple shortcomings in the metabolic-nutritional indices were observed in the vulnerable groups for nausea/vomiting (waist-hip ratio, degree of obesity), dyspnea (hemoglobin, iron), constipation (body fat mass, percent body fat), dysphagia (body fat mass, percent body fat), reflux (body weight, hemoglobin), dry mouth (percent body fat, waist-hip ratio), and taste (body weight, total body water, soft lean mass, body fat mass). The shortcomings in a single index were observed in the vulnerable groups for emotional functioning and pain (EORTC QLQ-C30) and for eating restrictions (EORTC QLQ-STO22).

Conclusions

Long-term postoperative QoL deterioration in emotional functioning, nausea/vomiting, pain, dyspnea, constipation, dysphagia, reflux, eating restrictions, dry mouth, and taste were associated with nutritional shortcomings. QoL item-level analysis, instead of scale-level analysis, may help to facilitate personalized treatment for individual QoL respondents.

Quality of life and nutritional consequences after aboral pouch reconstruction following total gastrectomy for gastric cancer: randomized controlled trial CCG1101

BACKGROUND

Total gastrectomy has detrimental effects on postoperative nutritional status and quality of life (QOL), but it is often unavoidable in the treatment of gastric cancer. Roux-en-Y (RY) is the most common reconstruction method following total gastrectomy. Trials to explore other means of reconstruction have been conducted but have failed to identify a method that is globally accepted.

METHODS

Aboral pouch reconstruction (AP), in which an anisoperistaltic jejunal pouch is created in the Y limb of the RY reconstruction, is considered effective and technically feasible. A prospective randomized trial was conducted to compare AP with RY. Gastric cancer patients requiring total gastrectomy for R0 resection were randomly assigned during surgery to receive either RY (n = 51) or AP (n = 49). Postoperative QOL as assessed by the EORTC QLQ-C30 and STO22, body composition, and morbidity were compared between the two reconstruction methods. The physical functioning score of the QLQ-C30 was selected as the primary endpoint.

RESULTS

The incidences of postoperative complications were similar between the two groups (29 % in the RY group and 27 % in the AP group). No significant difference was observed in the physical functioning score, and the superiority of AP was demonstrated only for the nausea and vomiting score at 12 months (p = 0.041) and the reflux score at 1 month (p = 0.036). No significant differences were observed in body composition or serum biochemistry.

CONCLUSIONS

Although AP was safely implemented, no increased benefits in nutritional or QOL-related parameters were observed for this method over RY within 12 months postoperatively.

Quality of life in cancer survivors 5 years or more after total gastrectomy: a case-control study

INTRODUCTION

This study investigated how total gastrectomy (TG), along with memories of cancer, affect the subjective wellness of survivors long after surgery. Rational approaches for effectively improving the quality of life (QoL) of these survivors were suggested.

METHODS

Between 2008 and 2013, QoL data of gastric cancer patients who underwent a curative TG, were obtained at 5-year postoperative follow-up visits (5-year survivors) and at visits beyond 5 years (long-term survivors). The control groups for these survivor groups were constructed from volunteers who visited our health-examination center for annual medical checkups. The Korean versions of the European Organization for Research and Treatment (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and the gastric cancer specific module, the EORTC QLQ-STO22, were used to assess QoL.

RESULTS

Five-year survivors showed worse QoL compared to the control group in role functioning, social functioning, nausea/vomiting, appetite loss, financial difficulties, reflux, eating restrictions, taste, and body image, and better QoL in the emotional and cognitive functioning scales. In long-term survivors, deterioration in QoL were still apparent in financial difficulties, reflux, and eating restrictions, while QoL differences in the remaining scales had diminished.

DISCUSSION

Surviving 5 years after TG does not result in living in a carefree state in terms of QoL. After 5 postoperative years, survivors still need extended care for deteriorated QoL indicators due to symptomatic, behavioral, and financial consequences of surgery.

CONCLUSION

While relevant clinical and institutional approaches are required for corresponding declines in QoL, such efforts must extend beyond 5 postoperative years.

Preservation versus non-preservation of the duodenal passage following total gastrectomy: a systematic review

BACKGROUND

Various reconstruction procedures have been proposed for restoring the alimentary tract continuity after total gastrectomy. However, so far there is no consensus on the ideal post-gastrectomy reconstruction procedure. The necessity of preserving the duodenal passage is one of the major focuses of the debate concerning gastrointestinal reconstruction and is the objective of this study.

METHODS

A systematic literature search of PubMed, EMBASE, the Cochrane Library, SCI, and Chinese Biomedical Literature Database (CBM) was carried out before March 2012 to obtain studies of randomized controlled trials (RCT). Analysis was performed using RevMan 5.0 software.

RESULTS

Nine RCTs involving 642 participants met the selection criteria. The results of the meta-analyses showed that operative mortality and morbidity were not significantly different between the two procedures (preservation vs. non-preservation of duodenum). However, operative time was considerably prolonged by preserving the duodenal passage. Patients in the preservation group had an improved nutritional parameters (body weight, levels of serum iron and hemoglobin) in the short term (<6 months) after surgery. Beneficial effect on preventing postgastrectomy symptom (heartburn, dumping syndrome) was not found by maintaining the duodenal passage throughout a 2-year follow-up. Moreover, a qualitative measurement showed that no significant quality of life improvement for patients with a preserved duodenal passage.

CONCLUSION

This systematic review failed to demonstrate obvious advantage in preserving duodenal passage after total gastrectomy.

Optimal size of jejunal pouch as a reservoir after total gastrectomy: a single-center prospective randomized study

BACKGROUND

In order to improve a patient's quality of life after total gastrectomy, jejunal pouch reconstruction has been employed. However, little information exists regarding the optimal size of the jejunal pouch after total gastrectomy.

METHODS

The study was designed as a single-center randomized trial in which the results of double-tract reconstruction with pouches of two different sizes were compared, i.e., short and long pouch double tract (SPDT and LPDT, respectively). We conducted a clinical assessment with standard questionnaire after surgery. The amount of residual food in the jejunal pouch was determined by endoscopy.

RESULTS

No demographic differences were noted between the two groups. The eating capacity per meal was higher in the SPDT group than in the LPDT group. The postoperative weight loss 24 months after surgery was lower in SPDT group than that in the LPDT group. Although the incidence of early dumping symptoms was higher in the SPDT group, no difference was noted in the other postprandial abdominal symptoms between the two groups.

CONCLUSIONS

We conclude that the optimal pouch should be relatively short, as a short pouch improves the eating capacity per meal and the weight loss ratio to the preoperative value.

[Quality of life of patients with cancer of the oesophagus and stomach]

The study of the health related quality of life in patients with digestive tract cancer, and particularly in those with tumours of the oesophagus and stomach, provides useful information for selecting the most suitable therapeutic option. It may also be used to predict the impact of the disease and its possible treatments on the physical, emotional and social condition of the patient. Various sensitive and reliable tools have been developed over the past decades that are capable of measuring the quality of life of patients; the use of questionnaires has made it easier to exchange information between the patient and the doctor. The pre- and post-operative variations in the quality of life in patients with oesophageal-gastric cancer are of prognostic value on the outcome of the disease. For all these reasons, the health related quality of life is currently considered, along with disease free survival and absence of recurrences, one of the most important parameters in order to assess the impact on the patients of a particular oncological treatment. The aim of this article is to review the role of the health related quality of life assessment, as well as the various tools which are available to measure it in patients with oesophageal-gastric cancer.

Distal pouch reconstruction with transverse jejunoplasty after experimental gastrectomy

PURPOSE

Various reconstruction methods with or without reservoir formation after total gastrectomy have been established. Transverse intestinoplasty has benefits as a functional peristalsis modification in rectal resections. In this study, we evaluate a distal pouch combined with a transverse jejunoplasty compared to standard Roux-en-Y reconstruction.

METHODS

Total gastrectomy was performed on 23 pigs randomly assigned to 3 reconstruction groups-group 1 (n = 7): esophagojejunostomy without a pouch, group 2 (n = 8): esophagojejunostomy with a distal pouch, and group 3 (n = 8): distal pouch with a transverse jejunoplasty. Seven days postoperatively, weight was measured, and X-ray examinations were conducted for 1 h after oral contrast medium application. Blood glucose levels after oral glucose intake and the volume of the pouch loop were evaluated.

RESULTS

Upper jejunal passage was delayed and the mean volume of the jejunal loop increased by pouch formation compared to controls (p < 0.05). Body weight was the best for the pouch group with jejunoplasty (-1.9 ± 0.8% vs. pouch alone -3.3 ± 2.4% vs. no pouch -7.5 ± 2.1%, p < 0.05).

CONCLUSIONS

The distal jejunal pouch after total gastrectomy offers advantages with respect to bowel passage and postoperative nutrition status compared to standard Roux-en-Y reconstruction. The combination of a distal pouch and transverse jejunoplasty may provide additional functional benefits.

Measurement and interpretation of patient-reported outcomes in surgery: an opportunity for improvement

BACKGROUND

Surgery may have a profound effect on patients' health-related quality of life (QOL). To be optimally useful, trials that seek to guide clinical decision making should measure outcomes that are important to patients and report the results in a clinically meaningful way. We sought to explore how researchers currently measure and interpret QOL in surgical trials, using gastric cancer as a case study.

METHOD

We performed a systematic review of randomized controlled trials (RCTs) of gastric cancer surgery published between 1966 and 2009 that included at least one patient-reported outcome (PRO). Investigators assessed trial eligibility and extracted data in duplicate using standardized forms, then resolved disagreements by consensus.

RESULTS

Our search identified 87 RCTs of gastric cancer surgery, of which 11 (13%) included at least one PRO. Ten RCTs measured one or more validated PROs, although six also included ad hoc measures. All manuscripts presented the results as raw scores and nine of the 11 trials identified a statistical difference between groups. All 11 manuscripts prominently reported the PRO results in the abstracts and conclusions, but only one discussed the clinical significance of the differences between groups.

CONCLUSIONS

Most RCTs of gastric cancer surgery do not include measures of QOL and those that do suffer from important limitations. RCTs would be more useful to surgeons and patients if authors measured PROs and utilized existing approaches to present the results of PROs in ways that provide an intuitive sense of the magnitude of effects.

Reconstruction after gastrectomy: which technique is best?

Several reconstruction techniques are possible after gastrectomy. The best reconstruction is one, that maintains satisfactory nutritional status and quality of life while keeping postoperative morbidity as low as possible. The aim of this study was to describe the different reconstruction techniques that can be proposed after distal and total gastrectomy, heeding to the French guidelines on the use of mechanical sutures in these indications. We then conducted a review of randomized trials dealing with reconstruction techniques after distal and total gastrectomy. After distal gastrectomy, Roux-en-Y reconstruction seems superior to Billroth I and Billroth II reconstructions in terms of functional outcomes and long-term endoscopic results and should be chosen in patients with benign disease or superficial tumors. Otherwise, Billroth II should be preferred over Billroth I reconstruction because of lower postoperative morbidity and better oncologic margins. After total gastrectomy, Roux-en-Y reconstruction remains the easiest solution, with satisfactory functional results. Addition of a pouch reservoir after Roux-en-Y reconstruction seems to improve short-term functional outcome after total gastrectomy with better potential for nutritional intake. In the long-term, quality of life seems better mainly in patients with small-resected tumors associated with a good prognosis.

Quality of life of long-term survivors after a distal subtotal gastrectomy

PURPOSE

The aim of this study was to investigate the impact of a distal subtotal gastrectomy on the quality of life (QoL).

MATERIALS AND METHODS

The QoL data of 126 patients were obtained on their 5th annual follow-up visit after a curative distal subtotal gastrectomy for gastric cancer (Group A). The QoL data of 130 age- and gender-adjusted healthy population were obtained from the individuals who visited the health screening center for a medical check-up (Group B). There were 42 women and 84 men in the study group and their mean age was 56.0±11.1 years. QoL was assessed using the Korean versions of the European Organization for Research and Treatment of Cancer (EORTC) QoL Questionnaire Core 30 (QLQ-C30) and QLQ-STO22.

RESULTS

The EORTC QLQ-C30 global health status and QoL scores of Group A and Group B were 63.9±22.7 and 61.3±22.1, respectively (p=0.361). Group A revealed a better score for emotional functioning (84.1±16.1 and 75.2±21.4, respectively; p<0.001), cognitive functioning (82.0±16.4 and 75.0±21.4, respectively; p=0.004) and fatigue (27.7±20.8 and 33.8±23.2, respectively; p=0.028). However, Group A revealed a worse score for nausea and vomiting (14.8±20.0 and 10.2±16.0, respectively; p=0.042), financial difficulties (14.8±22.9 and 7.1±16.1, respectively; p=0.002), reflux (16.7±17.7 and 10.1±17.0, respectively; p=0.003), eating restrictions (13.6±15.2 and 6.6±10.2, respectively; p<0.001) and body image (23.3±25.4 and 16.2±24.6, respectively; p=0.023).

CONCLUSION

The QoL of long-term survivors after a distal subtotal gastrectomy is still influenced by the surgery itself even though they are considered to be free of disease.

Pouch vs. no pouch following total gastrectomy: meta-analysis and systematic review

OBJECTIVES

Whether reconstruction after total gastrectomy for gastric malignancies should be done with or without a pouch is a controversial issue in clinical research. There is still no consensus on the reconstruction technique of choice. The aim of this report was to assess the value of pouch formation as a gastric substitute after total gastrectomy compared with reconstruction techniques without a pouch.

METHODS

A systematic literature search of the Medline database and the Cochrane Library was carried out and a meta-analysis executed according to the Quality of Reporting Meta-Analyses (QUOROM) statement. Only randomized controlled trials (RCTs) comparing reconstruction techniques with and without a pouch were eligible for inclusion. All trials were independently assessed by two authors. Data on perioperative parameters, postgastrectomy symptoms, eating capability, body weight, and quality of life were extracted from the RCTs for meta-analysis using random-effects models for the calculation of pooled estimates of treatment effects.

RESULTS

Nine RCTs comparing Roux-en-Y reconstructions with and without pouch and four RCTs comparing jejunal interpositions with and without a pouch were included. The results of the meta-analyses show that additional pouch formation does not significantly increase morbidity or mortality and does not considerably extend the operating time or the hospital stay. Patients with a pouch complained significantly less of dumping and heartburn and showed a significantly better food intake postoperatively. Quality of life was significantly improved in patients with a pouch compared with patients without a pouch. This difference even increased over time from 6 to 12 and 24 months postoperatively.

CONCLUSIONS

This meta-analysis highlights some clinical advantages of pouch reconstruction after total gastrectomy.

Comparing aboral versus oral pouch with preserved duodenal passage after total gastrectomy: does the position of the gastric substitute reservoir count?

BACKGROUND

Total gastrectomy results in a significant weight loss, different postgastrectomy symptoms, and a reduction in quality of life. Elaborate surgical reconstruction methods are evaluated to improve results. The present study compares two types of reconstructions--an aboral pouch with preserved duodenal passage and an oral pouch with preserved duodenal passage--differing only in the site of the pouch.

METHODS

Twenty-eight patients entered the study. Primary outcome measures--body weight, body mass index, and quality of life, and secondary outcome measures--serum nutritional parameters, scintigraphic small-intestinal passage, and lipid and carbohydrate absorption were measured 6, 12, and 24 months after surgery.

RESULTS

No significant differences were found in anthropometric parameters or in quality of life between the groups. Regarding the secondary outcome measures, albumin levels were higher in the oral pouch group, while protein and immunoglobulin-A levels were higher in the aboral pouch group.

CONCLUSION

The site of the reservoir does not significantly influence the outcome after total gastrectomy and reconstruction with a preserved duodenal passage.

Long-term benefits of Roux-en-Y pouch reconstruction after total gastrectomy: a randomized trial

OBJECTIVE

Roux-en-Y reconstruction with and without jejunal pouch was compared in a randomized controlled trial to identify the optimal reconstruction procedure in terms of quality of life.

BACKGROUND DATA

Randomized trials comparing techniques of reconstruction after total gastrectomy have shown controversial results.

METHODS

One hundred and thirty-eight patients with gastric cancer were intraoperatively randomized for Roux-en-Y reconstruction with pouch (n = 71) or without pouch (n = 67) after gastrectomy and stratified into curative or palliative resection. Intra- and postoperative complications were recorded. Body weight and quality of life were determined every 6 months with a follow-up of up to 12 years.

RESULTS

Both groups were comparable for age, sex, incidence of concomitant disease, and staging. There were no differences in operative time, postoperative complications, and mortality. Short- and long-term weight loss was similar in both groups. In the first postoperative year, there were no benefits of pouch reconstruction in terms of quality of life, independent of the resection status. In the third, fourth, and fifth year after surgery quality of life was significantly improved for patients with a pouch.

CONCLUSIONS

Roux-en-Y pouch reconstruction after gastrectomy is simple to perform and safe. Long-term survivors benefit from pouch reconstruction. Therefore, a pouch is recommended for patients with a good prognosis.

Systematic review: health-related quality of life (HRQOL) questionnaires in gastro-oesophageal reflux disease

BACKGROUND

Although gastro-oesophageal reflux disease (GERD) has a well-established pathophysiology, the impact of GERD symptoms on the patients' quality of life can be profound. Therefore, health-related quality of life (HRQOL) questionnaires have become standard instruments to evaluate the effect of treatment in clinical trials.

AIM

To evaluate the reliability, validity and responsiveness of available GERD-specific HRQOL.

METHODS

A systematic literature search using the Medical Subject Headings terms: 'Gastro-oesophageal reflux', 'Heartburn' and 'Oesophagitis' with 'quality of life' and 'questionnaires' was preformed to identify the available HRQOL questionnaires. To analyse the psychometric properties of the respective tools, the actual guidelines for the use of patient-reported outcomes in clinical trials were applied.

RESULTS

We identified five GERD-specific HRQOL questionnaires but none of them fulfilled all quality criteria; either they did not meet the actual standards for psychometric properties (HBQOL, GERD-HRQL, Jasani et al.Aust Fam Physician 1999; 28: 515), or were impracticable to use in clinical trials. The generic and hybrid instruments lack specificity and sensitivity and were not designed for treatment evaluation in GERD patients.

CONCLUSION

There is need for a new evaluative tool in the assessment of HRQOL during GERD therapy.

[Searching for the optimal reconstructive methods following total gastrectomy]

Three prospective randomised studies and a clinical experiment were performed to study postoperative weight, body mass index, nutritional and immunological laboratory parameters, gut motility, lipid and carbohydrate absorption, quality of life and gastrointestinal hormone production after total gastrectomy with different reconstructions. The first trial compared Roux-en-Y to a newly introduced aboral pouch construction, while the second study compared these two methods and the aboral pouch reconstruction with a preserved duodenal passage version. Improved lipid absorption and quality of life was detected for the aboral pouch reconstruction. In addition to these, the duodenal passage preserving version resulted in a better iron metabolism, too. The third study compared the aboral pouch to conventional oral pouch, both with duodenal passage preserving versions. No significant difference was detected between these two groups. In the fourth study, a clinical experiment was performed examining pre- and postprandial glucose, insulin, cholecystokinin and somatostatin levels in patients recruited from the first two randomised trials. Significant differences were demonstrated between the various reconstruction types: the duodenal passage preserving reconstruction provided close to physiological cholecystokinin and somatostatin productions, while with duodenal exclusion these levels were abnormally raised.

Clinical results of various reconstructions employed after total gastrectomy

Methods of restoring continuity after total gastrectomy, particularly those creating a "reservoir," have led to many publications over the last 20 years. These publications are herein reviewed in an attempt to answer questions regarding the clinical value of a jejunal "reservoir". The conclusion we reached from this review was that such a reconstruction does reduce unpleasant symptoms, aids weight maintenance, and is a valuable operative approach.

Effects of nutritional support long time after total gastrectomy

BACKGROUND & AIMS

Long-term effects of total gastrectomy on nutritional status are not well known, neither is the role of nutritional support. Dietary counselling is usually individualized, but generally not well defined. We aimed to evaluate effects of individualized oral nutritional support long time after total gastrectomy.

METHODS

Dietary advice was given, aiming for an energy and protein rich diet, using ordinary food and liquid supplements tailored to individual needs and preferences. Counselling was repeated monthly. Body weight and a 4-day food record were obtained at baseline, and thereafter-at month 1, 3, 6 and 12. Body composition, resting and total energy expenditure were measured at baseline and at 12 months.

RESULTS

Thirteen of 15 included patients completed the study. Though a trend of weight gain was seen after 1 month, there was no significant weight change at 12 months as weight development was quite heterogeneous. Six patients who remained healthy during the study (all with BMI<25) gained weight (p<0.05), while five patients with intercurrent co-morbidity and two with initial BMI>25 lost weight or remained stable.

CONCLUSIONS

Nutritional intervention long time after total gastrectomy did not change body weight, body composition or energy metabolism. Intercurrent co-morbidity appeared to have a major impact on outcome, as the nutritional support was more effective in patients who remained healthy and had a BMI<25.

Comparing reconstruction with ileocecal graft to jejunal interposition pouch after total gastrectomy in rats

After total gastrectomy, the ileocecal graft may act as a reservoir and protect against reflux but give rise to transposition of the ileum and cause possible changes in bile acid metabolism and nutrition. This study compared the ileocecal graft and jejunal pouch. Male Wistar rats weighing 265 +/- 22 g were submitted to sham operation (S), ileocecal interposition graft (IIG), and jejunal pouch interposition graft (JP) after total gastrectomy. Eight weeks later, the esophagus was examined for evidence of esophagitis. Nutritional biochemistry and weight profile were documented preoperatively and 8 weeks after surgery. The oral glucose tolerance test was performed. Thirty-three rats were operated on and 30 survived for 8 weeks. Esophagitis occurred in seven JP rats. Body weight was significantly higher in IIG than in JP rats (p < .05). Normal glucose tolerance to intragastric glucose load was observed in sham and operated rats. JP rats had a significant decrease in serum albumin, glucose, transferrin, hemoglobin, iron, folate, and calcium, compared to sham (p < .05). Cobalamine was significantly lower in IIG rats than in JP rats (p < .05). In the IIG and JP groups, serum/hepatic total bile acid did not differ significantly from preoperative and sham values. In conclusion, the IIG interposition graft in rats prevented esophagitis, preserved nutrition, and did not interfere with enterohepatic total bile acid circulation.

Function-preserving surgery for gastric cancer

Early gastric cancer (EGC) with 5-year survival rates exceeding 90% now accounts for nearly 50% of all gastric cancers treated at major institutions in Japan. D2 lymphadenectomy with resection of at least two-thirds of the stomach has been the mainstay of treatment for every stage of gastric cancer, including EGC. Post-gastrectomy syndrome is inevitable after surgery. Most of the symptoms resolve with time, though some patients suffer immensely for prolonged periods. Mucosal cancers rarely metastasize (3% or less). Surgeons have altered the traditional strategy for treatment which focused only on highly radical operations. The new strategy preserves patients' quality of life, while at the same time maintaining a high level of radicality, by employing a function-preserving operation which prevents post-gastrectomy syndrome. The Japanese gastric cancer treatment guidelines have standardized indications for the function-preserving surgery that is widely performed in Japan. There are various kinds of function-preserving operations, such as those reducing the extent of gastrectomy, and those providing nerve preservation, sphincter preservation, and formation of a new-stomach. Evaluation of preserved function is not satisfactory, because there is no gold standard for measuring gastrointestinal motor function and patients' quality of life.

Health-related quality of life among disease-free stomach cancer survivors in Korea

Previous studies about the quality of life (QOL) in stomach cancer survivors focused on selected clinical parameters and did not consider the broader implications for overall health and QOL. We evaluated the impact of demographic and treatment-related factors on the QOL of stomach cancer survivors. We asked 391 stage I-III stomach cancer survivors who had been disease-free for at least 1 year after surgery to complete a demographic questionnaire, the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire, and its stomach module, QLQ-STO22.Survivors undergoing total gastrectomy reported greater eating restrictions than those undergoing subtotal gastrectomy. Receiving chemotherapy or radiotherapy did not significantly affect any QLQ-C30 or QLQ-STO22 scores. Role and emotional functioning improved with increasing age, and stomach-specific symptoms (pain, eating restrictions, and anxiety) lessened. Compared with female survivors, male survivors had better physical and role functioning. Smoking status was also a significant negative predictor of physical functioning and anxiety. Comorbidities and selected demographic characteristics had a greater effect than type of treatment on the QOL of post-operative stomach cancer patients.

Jejunal pouch interposition with fundic-like plication after total gastrectomy

PURPOSE

We developed a technique of jejunal pouch interposition with a fundic-like jejunal plication (JPI-FP) for reconstruction after total gastrectomy (TG) for gastric cancer. The aim of this study was to investigate the advantages of JPI-FP over Roux-en-Y reconstruction (R-Y).

METHODS

Twenty-two patients who had undergone TG more than 1 year earlier were classified into two groups according to the method of reconstruction used: Group A (n = 7) underwent R-Y, and group B (n = 15) underwent JPI-FP. Group B was subdivided into two groups to examine the usefulness of additional pylorus preservation: group B1 (n = 8), pylorus (-) and group B2 (n = 7), pylorus (+).

RESULTS

Food intake and body weight were significantly higher in group B than in group A (P < 0.05). Reflux esophagitis was diagnosed in two of the group A patients, but in none of the group B patients. Excessive esophageal bile exposure, determined as the fraction time of esophageal bilirubin absorbance over 0.14 > 50%, was significantly higher in group A than in group B (P < 0.05). There was no significant difference in bile exposure in the jejunal pouch between groups B1 and B2.

CONCLUSIONS

JPI-FP is a superior method of reconstruction after TG to prevent excessive esophageal bile reflux and from a nutritional aspect. The advantage of pylorus preservation remains unconfirmed.

Quality of life in gastric cancer

AIM: To summarize the empirical research on assessing quality of life (QOL) in patients with gastric carcinoma.

METHODS: Literature searches were conducted in MedLine from 1966 to February 2004.

RESULTS: Twenty-six studies were identified. QOL was used as an outcome measure in virtually all identified studies, such as those examining the effects of gastric cancer and various medical or surgical treatments in the patients. QOL was assessed mainly with generic measures; the social dimensions of QOL were largely neglected. The lack of gastric cancer-specific QOL measures hampers QOL research up to now. The gastric cancer-specific EORTC-QLQ-STO22 and the FACT-Ga are important additions to the arsenal of disease-specific QOL measures. In most of the studies, the label QOL is used for questionnaires, which only assess symptoms or performance status, or are physician-reported rather than patient-reported outcomes.

CONCLUSION: QOL in patients with gastric cancer deserves more systematic studies, especially as one of the outcome measures in randomized clinical trials. Results of studies that include QOL in patients with gastric cancer should be applied in clinical care, which aims at improving QOL of these patients.

Total gastrectomy with substitution of stomach by jejunal pouch with and without duodenal passage: study in rats

PURPOSE: A comparison was done between the F. Paulino jejunal pouch (FP) and a jejunal pouch (JP) as esophagus-duodenum interpositional graft, for replacing the stomach after total gastrectomy. It was investigated the effect of the two procedures on esophagus histology, nutritional state and serum gastrin in rats. METHODS: Male Wistar rats weighing 282±17g were randomly submitted to sham operation (S), FP and JP after total gastrectomy. After eight weeks the rats were killed with overdose of anesthetic and tissue was taken from the distal esophagus for histology. Serum levels of total proteins, albumin, iron, transferring, folate, cobalamine, calcium, as well as serum gastrin were determined. Survival was considered. RESULTS: Fourty six rats were operated and thirty survived for eight weeks. Five (33.3%) died after FP and 11 (52.3%) after JP (p<0.05). Postoperative esophagitis occurred in 6 JP rats. At 8th week, no difference was observed on body weight when compared FP and JP rats (p>0.05). The JP rats had a significant decrease in serum albumin, glucose, transferrin, iron, folate and calcium, compared to sham (p<0.05). Serum gastrin, iron and calcium were significantly higher in JP rats than in FP rats (p<0.05). In FP rats, transferrin and cobalamine showed significant decrease comparing the preoperative with 8th week levels (p<0.05). CONCLUSION: F. Paulino pouch in rats had lower mortality than JP, and esophagitis was not detected in it. JP rats had serum gastrin, iron and calcium unaffected, possibly because of preservation of duodenal passage.

Postoperative functional evaluation of jejunal interposition with or without a pouch after a total gastrectomy for gastric cancer

BACKGROUND

The objective of this study was to compare the motility of a gastric substitute after jejunal interposition without a pouch and jejunal interposition with a pouch and to evaluate the relationship of both methods with nutritional outcome.

METHODS

Twelve patients with gastric cancer treated by total gastrectomy and reconstruction with jejunal interposition without a pouch (J-I) and 14 patients treated by total gastrectomy and reconstruction with jejunal interposition with a pouch (J-P) were investigated in regard to the motor activity of the interposed jejunum and changes in body weight and dietary intake.

RESULTS

Phase III of the interposed jejunum without a pouch was observed over a 3-month follow-up, but phase III of the interposed jejunum with a pouch was not observed in any patient within 3 months of surgery. In the fed state, the motor activity of the interposed jejunum without a pouch increased significantly in patients within 12 months of follow-up, but in the interposed jejunum with a pouch, it did not. The amount of food consumed by the J-I group was significantly greater than that consumed by the J-P group.

CONCLUSIONS

This study demonstrates that the interposed jejunum with a pouch shows marked disturbances from the motor pattern of a normal jejunum during the fasting and fed states. These motor abnormalities may be responsible for insufficient food intake of the J-P group.

Techniques of reconstruction after total gastrectomy for cancer

BACKGROUND

Jejunal pouch formation and restoration of duodenal transit have been suggested for reconstruction after total gastrectomy. Opinions about the clinical value vary.

METHODS

The literature was searched for prospective randomized trials comparing reconstructive procedures after total gastrectomy for malignancy. Reports with at least an English or German abstract were included. Immediate results were evaluated in terms of postoperative deaths and complications. Long-term outcome was analysed using trends in bodyweight and quality of life.

RESULTS

A total of 19 randomized trials including 866 patients was identified. The operative risk of total gastrectomy was low, with a median mortality rate of 0 (range 0-22) per cent, irrespective of the method of reconstruction. Neither gastric substitution nor restoration of duodenal transit was associated with significant procedure-related complications. Results for specific reconstructions varied considerably within and between individual trials. Jejunal pouch reconstruction, but not restoration of duodenal passage, was associated with improved food intake and a tendency for weight gain in the early postoperative months. A favourable perception of quality of life persisted in the long term in some studies.

CONCLUSION

Preservation of duodenal transit offers little clinical benefit. Construction of a small-bowel reservoir after total gastrectomy should be considered to improve early postoperative eating capacity, bodyweight and quality of life.

Gastric Adenocarcinoma

Adenocarcinoma of the stomach is advanced enough in some patients to preclude curative treatment, but many gastric cancer patients have what appears to be localized disease that is amenable to surgical resection, which is the only truly effective treatment. Long-term results of what appear to be "curative resections" are relatively poor, however, and new management tools such as sentinel lymph node biopsy, recently promising adjunctive therapies (such as radiochemotherapy), and the organization of the order of treatment combinations do require further study with an eye to improving outcomes. However, there appears to be little hope for a dramatic improvement in treatment results from these innovations for patients with established gastric cancer. Fortunately, gastric cancer in the United States has gone from being the number one cause of cancer death in our population 50 years ago to that of being the number eight cause of cancer death at this time. This intriguing major decrease in the incidence of this disease must be considered secondary to one or more changes in our own environment that we hope will be exploitable in the future. As with cancers of all types and in all sites, a prevention strategy may prove more effective than the treatment strategies that are outlined here. The management strategies outlined are hopefully only temporary ones until we are able to develop a better handle on primary prevention.

Old and new TNM in carcinoma of the gastric antrum: analysis of our personal experience

Various tumor node metastasis (TNM) classifications have been proposed for staging of gastric carcinoma, including the fourth edition of the TNM classification and the Japanese Research Society for Gastric Cancer (JRSGC) system. In 1997 the fifth edition of TNM classification introduced the concept of the number of metastatic lymph nodes. We review our experience with staging gastric cancer in light of both the fourth and fifth editions of the TNM classification system. From January 1986 to December 1997, we performed subtotal resection in 193 patients with carcinoma of the gastric antrum. A total of 147 patients presented with criteria from the fifth TNM edition. We compared data from these patients with data from the fourth TNM edition. We analyzed 84 females and 63 males whose average age was 68.9 years. The average number of lymph nodes removed was 16.7. We used the Kaplan-Meier method to analyze survival. In accordance with the fourth TNM edition, we recorded 82 patients who were pN0, 36 who were pN1, and 29 who were pN2; according to the fifth edition, 82 patients were pN0, 33 were pN1, 17 were pN2, and 15 were pN3. Average follow-up was 26.7 months, and average survival was 56.9 months for N0 patients, 38.7 months for N1 patients, and 24.5 months for N2 patients staged according to the fourth edition. According to the fifth edition, survival was 39.3 months for N1 patients, 33.6 months for N2 patients, and 10.3 months for N3 patients. The survival curve was statistically different (P<0.001) between N0 and N1 patients according to the fourth edition; there was no significant difference between N1 and N2 patients. According to the fifth edition, the difference in survival probability was P<0.001 between N0 and N1 patients and N2 and N3 patients. The fifth TNM edition presents a greater ease of stratification in bringing together and mediating diverse cultural experiences between West and East. This staging lays the basis for a more accurate comparison between the groups.

Ideal reconstruction after total gastrectomy by the interposition of a jejunal pouch considered by emptying time

To establish the ideal form of the pouch for jejunal pouch interposition reconstruction (JPI) after total gastrectomy, the postoperative gastrointestinal function and symptoms were investigated in comparison with jejunal interposition reconstruction (JI). A total of 20 patients who underwent curative surgery for gastric cancer were enrolled in this study. In the JI group (n = 9), an isoperistaltic jejunum about 40 cm in length was interposed between the esophagus and the duodenum. In the JPI group n = 11), a proximal pouch about 15 cm in length with a 10-cm conduit was also interposed between the esophagus and the duodenum. At follow-up 6 months postoperatively, food transit was evaluated using a radiolabeled semisolid test meal. The half-emptying time was 6.9 minutes in the JI group and 46 minutes in the JPI group. The reservoir function influenced the recovery of the patients' body weight and development of the serum total protein in the early postoperative period. An early half-emptying time caused dumping symptoms in JI group. In the JPI group, there were no dumping symptoms; however, extended food clearance of pouch causes postprandial symptoms such as reflux (1 patient), vomiting (2 patients), and discomfort (2 patients). In those patients with symptoms, half-emptying times were longer than 60 minutes. There was a statistically significant correlation between the pouch length and the half-emptying time of the gastric substitute in JPI group (p = 0.0039, r = 0.789). If we estimate that the appropriate half-emptying time is 20 to 60 minutes, correlation of the pouch length and the half-emptying time shows that the ideal pouch length is about 12-15 cm in JPI. In jejunal pouch interposition reconstruction after total gastrectomy, an adequate procedure leads to nutritional advantage and prevents postoperative symptoms.

Gastric cancer

The past decade has seen many advances in knowledge about gastric cancer. Notably, tumour biology and lymphatic spread are now better understood, and treatment by surgical and medical oncologists has become more standardised. Since refrigerators have replaced other methods of food conservation, Helicobacter pylori has become a factor in the cause of gastric cancer. Cancers that arise at the oesophagogastric junction might be further examples of wealth-associated disease. To tailor treatment better, the western hemisphere needs to borrow from the East by establishing screening programmes for early diagnosis, through careful surgical resection, and through detailed analysis of tumour spread. In Europe and the USA, most patients reach treatment with cancers already at an advanced stage. For these patients, three important randomised trials are underway that evaluate combined therapy. Cytostatic drugs, especially angiogenesis inhibitors have proved disappointing; however, basic research efforts to detect familial gastric cancers and to assess minimally residual disease look more hopeful.

Total gastrectomy: options for the restoration of gastrointestinal continuity

Total gastric resection and the subsequent selection of the optimum procedure for reconstruction of the oesophageal-intestinal tract is a highly debated topic. Many different types of reconstruction have been proposed, but attempts to objectively validate the potential advantages of these techniques of have not produced any definitive conclusions. The main aim of reconstruction should be to maintain the nutritional status and quality of life of the patient, with the additional goal of achieving similar function to normal gut. In this review, we discuss the prospectively randomised studies of gastrointestinal reconstruction that were done between 1987 and 2002.

Preventive gastrectomy in patients with gastric cancer risk due to genetic alterations of the E-cadherin gene defect

BACKGROUND

Germline mutations in the E-cadherin gene CDH1 have recently been described that seem to be responsible for the development of hereditary diffuse gastric cancer.

METHODS

The world literature on familial gastric cancer is reviewed in terms of mutations of the E-cadherin gene CDH1.

RESULTS

There are reports of 18 families worldwide with hereditary diffuse gastric cancer due to germline mutations of the E-cadherin gene CDH1. Germline mutations of the E-cadherin gene CDH1 lead to hereditary diffuse gastric cancer with a penetrance of about 70%. An early onset with an average age of 38 years in men and women is typical for this autosomal dominant inherited disease. Until now preventive total gastrectomies with hereditary diffuse gastric cancer have been reported in five patients.

CONCLUSIONS

Preventive total gastrectomy should be the procedure of choice in patients with a germline mutation of the E-cadherin gene CDH1. Patients with a genetic risk for familial gastric cancer who reject preventive total gastrectomy must be followed-up intensively by endoscopy every 6-12 months.

Quality of life in patients with cancers of the upper gastrointestinal tract

Accurate assessment of health-related quality of life in patients with upper gastrointestinal cancers is essential to help determine treatment strategies. Questionnaires may be used to screen for physical and psychosocial morbidity, to evaluate new therapies and there is accumulating evidence to suggest that quality of life scores have prognostic value. There are well validated generic measures of quality of life suitable to use in patients with cancers of the upper gastrointestinal tract, but only two systems (EORTC QLQ-C30 and the FACT-G) have site-specific modules that have been constructed for this patient group. The future use of computer-assisted techniques to collect, analyze and interpret quality of life data will enable the implementation of quality of life results in clinical practice.

Usefulness of reconstruction with jejunal pouch in total gastrectomy for gastric cancer in early improvement of nutritional condition

BACKGROUND

Roux-en-Y reconstruction with a jejunal pouch is a modified standard procedure in total gastrectomy for gastric cancer. The aim of the current study was to evaluate the usefulness of the reconstruction using a jejunal pouch in subsequent improvement of the nutritional condition of patients with gastric cancer after total gastrectomy.

METHODS

Sixteen patients with gastric cancer treated by total gastrectomy and reconstruction with simple Roux-en-Y from January 1993 to December 1996 and 14 patients treated by total gastrectomy and reconstruction with Roux-en-Y and jejunal pouch from January 1997 to December 1998 were investigated in regard to postoperative heartburn, changes in the body weight, and prognostic nutritional index.

RESULTS

Postoperative heartburn occurred in 1 patient (7.1%) among patients treated with Roux-en-Y and jejunal pouch and 3 (18.8%) among patients treated with simple Roux-en-Y. The body weight ratio at 1 year after operation in patients treated with Roux-en-Y and jejunal pouch (88.2% +/- 4.2%) was significantly higher than that in patients treated with simple Roux-en-Y (80.0% +/- 4.6%; P <0.01). The prognostic nutritional index ratios for patients treated with Roux-en-Y and jejunal pouch at 1 and 3 months after operation were 93.9% +/- 9.1% and 101.7% +/- 11.0%, respectively, and were significantly higher than that in patients treated with simple Roux-en-Y (86.2% +/- 8.8% and 88.1% +/- 8.2%, P <0.05 and P <0.01, respectively).

CONCLUSIONS

Reconstruction using a jejunal pouch in total gastrectomy is useful for an early improvement of the nutritional condition of patients with gastric cancer.

Development of an EORTC disease-specific quality of life module for use in patients with gastric cancer

Quality of life (QL) is an important outcome in clinical trials in oncology. There is currently no valid international QL measure for gastric cancer. This paper describes the development of a QL module for gastric cancer to supplement the European Organization for Research and Treatment of Cancer (EORTC) Quality of life (QLQ-C30) questionnaire. Phases I to III of module development were conducted in the United Kingdom, France, Germany and Spain according to EORTC QL Group guidelines. Twenty relevant QL issues were generated from the literature and interviews with health professionals (n=24) and patients (n=58). This produced a 24 item provisional module. Further testing in 115 patients resulted in the QLQ-STO22, containing 22 questions, conceptualised into five scales and four single items, related to disease symptoms, treatment side-effects and emotional issues specific to gastric cancer. The use of the QLQ-C30 supplemented by the QLQ-STO22 will provide a comprehensive QL measure for international trials in gastric cancer.

Simple versus double jejunal pouch for reconstruction after total gastrectomy

BACKGROUND

Even though many types of reconstruction after total gastrectomy have been proposed to reduce postgastrectomy syndromes, choosing a method that would further improve the quality of life and nutrition of the gastrectomized patient is controversial. Hunt-Lawrence single pouch reconstruction seems to obtain better results compared with the more common Roux-en-Y technique, but both of these reconstructive approaches are associated with some reduction in food intake and some problems in achievement of ideal body weight.

METHODS

In this prospective, randomized trial, after total gastrectomy 18 patients had reconstruction according to the Hunt-Lawrence or single pouch technique (SP group), whereas for 23 patients, the technique was modified with construction of a second pouch in the distal portion of the jejunal loop (DP group). Patients in the two groups were compared at 12 months after surgery for problems in gastrointestinal function, quality of life, improvement in body weight and nutritional parameters, serum albumin, hemoglobin level, and serum protein.

RESULTS

The DP group demonstrated fewer symptom problems, better weight maintenance, and better laboratory values when compared with patients undergoing standard single jejunal pouch reconstruction.

CONCLUSIONS

Reconstruction with use of a double pouch as a gastric substitute leads to better outcome assessments than with a single pouch reconstruction. Our double pouch technique has demonstrated significant improvement in quality of life and nutritional recovery in terms of functional results as well as patient satisfaction.

Symptoms after total gastrectomy on food intake, body composition, bone metabolism, and quality of life in gastric cancer patients--is reconstruction with a reservoir worthwhile?

Gastric cancer is worldwide one of the most common causes of cancer death. Operation is the only treatment at this time that cures some patients. The side effects of the operation are, however, considerable, and include postoperative weight loss, loss of appetite, and other metabolic and nutritional changes. The recovery is very slow and incomplete. Reconstruction with different types of pouches has been asserted to facilitate the nutritional recovery, but results from different studies are somewhat contradictory. Malnutrition, osteoporosis, osteomalacia, and impaired quality of life are often but not always described. We can, however, establish that after a total gastrectomy, gastric cancer patients are very much at risk for these complications, which are probably caused by impaired food intake and steathorrhea even when the patients are cured from their cancer disease. In order to minimize the nutritional problems, it is crucial to avoid anastomotic narrowing and bile reflux. Roux-en-Y reconstruction seems to be the method of choice. Evidence from several randomized studies now speak in favor of including some type of pouch in the reconstruction. The most commonly used pouch today is the jejunal J-pouch. How the effect is exerted is not clear. Probably both the reservoir function of the pouch and changes in intestinal transit time are important. The importance of nutritional surveillance of these patients should not be underestimated, and most of the observed differences from various reports are probably due to dissimilarity in the follow-up protocols. A patient surviving his/her cancer has a decreased risk of developing severe disturbances in bone metabolism, food intake, body composition, and quality of life if the patient is under concerned nutritional surveillance and reconstructed with a pouch.

Surgical treatment of chronic pancreatitis and quality of life after operation

In conclusion, surgical therapy in patients with chronic pancreatitis may be characterized as follows: 1. Independently, several investigators have found intraductal and intraparenchymatous hypertension in patients with chronic pancreatitis. Decompression of the ductal system as the main principle of surgical therapy achieves clinical pain relief in most patients with chronic pancreatitis. The precondition is a consequent drainage of the main pancreatic duct and tributary ducts of second and third order up to the prepapillary region. The presence of an inflammatory tumor in the head of the pancreas or ductal abnormalities in the prepapillary region or a pancreas divisum requires performance of an extended drainage operation (LPJ-LPHE) to achieve pain relief and an improved quality of life. An extended drainage operation effectively manages complications arising from adjacent organs, such as distal common bile duct stenosis, segmental duodenal stenosis, and internal pancreatic fistulas. The extent of decompression has to be tailored to the anatomic and morphologic situation of the patient. 2. In patients with chronic pancreatitis, the main pancreatic duct is usually dilated. A small duct (3-5 mm) is only small for the surgeon. For the sclerosing entity of chronic pancreatitis with a truly small duct, that is, less than 3 mm in diameter ("small duct disease"), a longitudinal V-shaped excision of the ventral pancreas, as opposed to left resection, provides a new perspective for a sufficient drainage. 3. In the presence of segmental portal hypertension, a simple or extended drainage operation does not result in a normalization of the portal venous blood flow; however, how often relevant upper gastrointestinal hemorrhage develops from segmental portal hypertension is unclear. Therefore, the clinical relevance of this special problem needs further evaluation. 4. Postoperative morbidity of LPJ-LPHE is significantly lower in comparison to resectional procedures, such as PD, PPPD, and DPRHP. A lower perioperative mortality rate is not justified anymore as a relevant criterion in favor of drainage procedures because resectional procedures are burdened by a minimal or no mortality in experienced centers; however, PD and PPPD are greatly hampered by a significantly decreased postoperative global quality of life as opposed to the LPJ-LPHE. This is reflected by a significantly lower rate of social and professional rehabilitation. 5. The incidence of exocrine and endocrine organ dysfunction is lower after LPJ-LPHE compared with PD or PPPD, but not compared with DPRHP. Preservation of the gastroduodenal passage and the continuity of the bile duct with its associated feedback mechanisms of exocrine pancreatic secretion and glucose metabolism seem to be responsible for this phenomenon. 6. An early surgical or endoscopic interventional drainage of the hypertensive pancreatic duct system possibly offers the chance to favorably manipulate the natural course of chronic pancreatitis with regard to a delayed onset of exocrine or endocrine insufficiency. 7. Late mortality reflects continued alcohol abuse rather than the effect of an operative procedure.

Evaluation of esophageal bile reflux after total gastrectomy by gastrointestinal and hepatobiliary dual scintigraphy

Conducting the qualitative evaluation of reconstruction methods is difficult because of their complexity. The aim of the present study was to compare esophageal bile and food reflux by performing gastrointestinal and hepatobiliary dual scintigraphy (GHDS) after various methods of reconstruction following total gastrectomy. Of 17 patients studied, 4 had undergone Roux-en-Y anastomoses (R-Y); 6, jejunal pouch-Y anastomoses (P-Y); and 7, jejunal pouch interposition (P-I). GHDS was performed 1 year after surgery using 111In-diethylene triamine pentaacetic acid administered orally, and 99mTc-pyridoxyl-5-methyl tryptophan administered intravenously. Imaging data from a gamma camera were stored in and processed by a data analyzer. Three patients who had undergone R-Y and one who had undergone P-I complained of heartburn, while one who had undergone R-Y, two who had undergone P-Y, and three who had undergone P-I complained of a feeling of fullness. Esophageal bile reflux was confirmed by GHDS in four of the patients who had undergone R-Y, one who had undergone P-Y, and four who had undergone P-I. Moreover, GHDS demonstrated food retention in two patients who had undergone R-Y, five who had undergone P-Y, and four who had undergone P-I. Weight loss was closely related to the esophageal reflux of bile or food which can be accurately detected by GHDS. Despite the absence of heartburn, patients diagnosed as having bile reflux by GHDS showed poor recovery of body weight.

Long-term beneficial effects of a gastric reservoir on weight control after total gastrectomy: a study of potential mechanisms

BACKGROUND

Weight loss after total gastrectomy is a regular occurrence. Reconstruction with a gastric substitute has been suggested to facilitate recovery, but few randomized studies are available.

METHODS

In a randomized study comparing subtotal, total and total gastrectomy with an S-shaped pouch, 36 patients who had total gastrectomy with or without a pouch survived for more than 3 (mean 5.2) years. Body composition (four-chamber model, dual-energy X-ray absorptiometry, anthropometric data) was evaluated before operation, after 12 months and at long-term follow-up. Food intake was registered as a 4-day food record at 12 months and at long-term follow-up.

RESULTS

At long-term follow-up those allocated to the gastric substitute arm had lesser degrees of weight loss consisting mainly of the depletion of body fat stores, whereas lean body mass showed no significant decrease when adjusted for the process of ageing. There was no significant difference in food intake.

CONCLUSION

Reconstruction with an S-shaped gastric substitute facilitates long-term recovery after total gastrectomy and should be considered when the prognosis is favourable.
