Gastrectomy with combined resection of other organs for carcinoma of the stomach with invasion to adjacent organs: clinical efficacy in a retrospective study.

BACKGROUND: Carcinoma of the stomach invading one or more adjacent organs raises serious concerns over en bloc dissection because en bloc resection has an associated high risk and such advanced carcinoma is frequently associated with incurable factors. Thus, it is important to understand the efficacy of gastrectomy combined with other organ resection and to refine the indications for en bloc dissection. STUDY DESIGN: Seventy-seven patients with carcinoma of the stomach directly invading adjacent organs or structures were analyzed retrospectively to investigate the efficacy of en bloc resection. Forty-one patients underwent gastrectomy combined with resection of one or more invaded organs (combined resection group), while the other 36 patients underwent gastrectomy with palliative abrasion between the primary tumor and the invasion site (noncombined resection group). RESULTS: The five-year survival rate was 23 percent in the combined resection group and 0 percent in the noncombined resection group (p < .05). The 23 curative cases and 18 noncurative cases in the combined resection group had a survival rate of 41 percent and 0 percent, respectively (p < .05). The survival rate after a single organ resection was 29 percent, and after a multiple organ resection, 0 percent (p < .05). Cases of carcinoma invading either the pancreas or mesocolon had a slightly but not significantly better prognosis. In Borrmann type IV carcinoma there was no difference in survival between the curative and noncurative operation. Cases with P1 dissemination had a better prognosis than those of P2 and P3 dissemination. CONCLUSIONS: The best indication for an en bloc combined organ resection was an invasion limited to only one other organ, not more than N2, no incurable factor, and any type except Borrmann type IV. Additionally, an en bloc combined resection would be worth trying for any type of gastric carcinoma with not more than P1 dissemination and with no other incurable factor.

Prediction of hospital stay after total gastrectomy.

The following factors were tested in the Cox proportional hazards model to determine their relationship to postoperative hospital stay in 174 patients who underwent total gastrectomy: age, sex, tumour stage, tumour free resection margins, anastomotic leakage, size of the EEA-stapler, preoperative hospital stay, location of the anastomosis and additional resection. Only anastomotic leakage and age independently affected postoperative hospital stay. Leakage, confirmed radiologically, developed in 20 patients (11.5%) of whom four died postoperatively. Another six patients who did not develop leakage also died, giving a postoperative mortality of 5.7%. The median age of the patients was 68 years (range 30-87), and the median postoperative hospital stay was 15 days (range 3-192). The operations were performed by 30 different surgeons of whom four performed more than ten, 9 performed 4-10 and 17 performed 1-3 total gastrectomies. There was a significant difference in postoperative mortality- and anastomotic leakage-rate between the surgeons who operated more than ten and less than four (p = 0.0122, p = 0.0453). However, when comparing the surgeons who operate more than 10 and 4-10 there was no difference in mortality or anastomotic leakage (p = 0.3493, p = 0.8867). When comparing the surgeons who operated on 4-10 with less than 4 there was no difference in postoperative mortality, but the anastomotic leakage rate was of borderline significance (p = 0.3916, p = 0.0582). Between the surgeons with the greatest experience there were significant differences as to leakage rate (p = 0.0003), time of operation (p < 0.001) but not in the number of thoracoabdominal incisions (p = 0.4939) or postoperative mortality (p = 0.8394). This study has shown conclusively that anastomotic leakage is the most important factor for prediction of postoperative hospital stay after total gastrectomy.

Helicobacter pylori infection after partial gastrectomy for peptic ulcer and its role in relapsing disease.

OBJECTIVE: To elucidate the role of Helicobacter pylori in relapsing disease after partial gastrectomy for peptic ulcer. DESIGN: Retrospective study of gastroscopies between January 1985 and February 1988. SETTING: Department of Surgery, Helsinki University Central Hospital, Finland. PARTICIPANTS: One hundred and fifty-five patients, who had undergone partial gastrectomy for peptic ulcer disease. MAIN OUTCOME MEASURES: Correlation between clinical and laboratory data, macroscopic findings at gastroscopy and histopathology. RESULTS: At gastroscopy 41 patients showed an ulcer at the site of anastomosis or in the gastric stump and two patients had a history of a previous ulcer recurrence. The median time interval between operation and relapse was 4 years. There was no correlation between ulcer recurrence, sex, age, ABO blood group or other diseases. Smokers and patients using non-steroidal anti-inflammatory drugs (NSAIDs) or alcohol had more relapses, but the difference was not significant. The recurrence rate was higher after Billroth II (BII; 34%) than after Roux-en-Y (14%; P = 0.03) or Billroth I (BI) reconstruction (24%). Giemsa staining demonstrated H. pylori in the gastric stump of 37% of the patients. H. pylori expression was related to age but unrelated to sex, ABO blood group, NSAID use, smoking or alcohol consumption. H. pylori positivity was more common (52%) after BI than after BII (28%; P = 0.04) or Roux-en-Y resection (40%). Recurrent ulcer was more often found in gastric remnants with normal mucosa (36%) than in those with H. pylori-positive gastritis (18%; P = 0.03) or H. pylori-negative gastritis (26%). CONCLUSION: It seems that H. pylori infection plays a minor role in the pathogenesis of ulcer recurrence after partial gastrectomy for peptic ulcer disease. Eradication of H. pylori of the remnant stomach is therefore presumably not effective in preventing ulcer recurrence.

[Jejunal pouch interposition after total gastrectomy].

The results and procedures of interposed jejunal pouch after total gastrectomy for gastric cancer are reported. Basic requirements of reconstruction after total gastrectomy are 1) formation of a food reservoir, 2) maintenance of duodenal continuity, 3) avoidance of reflux esophagitis, 4) gradual emptying of reservoir into the small intestine. Since 1950's, several procedures of gastric substitutes have been reported. But they were not widely performed. Because scientific evaluation of the value of gastric substitutes was difficult and the operative procedures were time consuming and complicated. With an increasing ratio of early gastric cancer in 1990's, the importance of post-operative QOL, such as food intake and body weight maintenance, in patients after total gastrectomy has been recognized. Our procedure is a double lumen jejunal pouch distal to a interposed jejunum. The length of interposed jejunum is 20 cm and that of pouch is 10 cm. Using surgical staplers, this procedure is safe and simple. Jejunal pouch interposition leads to a satisfactory symptomatic and nutritional result in gastrectomized patients.

[Pedicle transplantation of a transverse colon segment after total gastrectomy].

UNLABELLED: This report is concerned with series of patients with advanced gastric cancer in whom transverse colon segment interposition, namely an end-to-end esophagocolostomy plus coloduodenostomy (Type-I) from 1965 to 1970 and an end-to-side esophagocolostomy plus coloduodenostomy (Type-II) from 1986 to 1996 were performed after total gastrectomy. Fifty-two patients with Type-I reconstruction and 133 patients with Type-II reconstruction after total gastrectomy were studied. Postoperative nutritional condition and complications were investigated and changes in the size and high amplitude propagated contractions of the interposed colon were measured. RESULTS AND CONCLUSION: The interposed transverse colon segment which was placed in an iso-peristaltic fashion between esophagus and duodenum dilated gradually and capable of taking a reasonable quantity of food at one time. The nutritional status was good especially in long-term survivors. Complications such as reflux esophagitis (12.0% after Type-I and zero% in Type-II fashion) have occurred. The iodinated Triolein 131I absorption test has shown 92.4% absorption rate of the material, a value comparable to that of patients subjected to Billroth-I type gastric resection. In conclusion, pedicle transplantation of a segment of the transverse colon, especially Type-II fashion, is feasible and useful to use in patients undergoing total gastrectomy.

[A new reconstructive procedure, interposition of a jejunal pouch after proximal gastrectomy].

In this chapter we mention the significance or advantage of the new reconstructive procedure, interposition of a jejunal pouch after proximal gastrectomy. Instead of oesophagogastrostomy which often brought many postoperative complications, various techniques of anastomosis such as conventional jejunal interposition or double tract method were contrived. Although these techniques could reduce the incidence of postoperative problems such as reflux oesophagitis, it is very difficult to examine or remedy beyond the oesophagojejunostomy site after surgery. On the other hand, interposition of a jejunal pouch showed us many advantages. The volume of reconstructed stomach was adequate and the patients could eat enough actually. In case of need, endoscopic fiber could enter the remnant stomach or duodenum very easily. This is the big advantage for the treatment of the upper GI and hepato-biliary pancreatic diseases endoscopically or radiologically after proximal gastrectomy. For these reasons, we usually use interposition of a jejunal pouch between the oesophagus and remnant stomach after proximal gastrectomy.

[A device in reconstruction method after distal subtotal gastrectomy: special reference to double tract method with jejunal pouch].

In the surgery of gastric cancer, it is necessary to consider not only the curability of gastric resection but also the quality of life of the patients in the choice of reconstruction method after distal gastrectomy. We have devised the jejunal pouch double tract method after gastrectomy. We reported in this study on the details of method and the satisfactory results. We employed 15 cases of gastric cancer which should be resected over three quarters of the stomach because the tumor occupation were in the middle third of the stomach and were expected long survival period. The operative procedure was as follows: (1) completion of gastric resection and lymph node dissection, (2) separation of jejunum at the site of 25 cm anal side from the Treitz's ligament, (3) pulling up the anal side of the jejunum preparing double jejunal pouch with approximately 10 cm in length using GIA, (4) anastomosis between residual stomach and jejunal pouch, (5) duodenojejunostomy at the site of 3-5 cm anal side from the pouch, (6) jejunojejunostomy at the site of 15 cm anal side from the duodenojejunostomy. Double tract reconstruction with jejunal pouch after distal gastrectomy is well-balanced method in the storage and discharging capacity, and useful in the view of better quality of life, especially in the cases which could be expected long survival period.

Amylase concentration of drainage fluid after total gastrectomy.

BACKGROUND: Pancreatic fistula is a serious complication of total gastrectomy with splenectomy. The amylase content of drainage fluid was examined and its usefulness for predicting pancreatic complications after gastrectomy was evaluated. METHODS: The amylase concentration of the fluid in the peripancreatic drain was determined prospectively in 102 patients who underwent total gastrectomy in 1995. RESULTS: Pancreatic fistula developed in 13 patients, whose drainage fluid amylase levels on the first postoperative morning were significantly higher than those of patients without fistula formation. Among 27 patients with amylase levels exceeding 4000 units, eight later developed pancreatic fistula, while only five (7 per cent) of 68 with amylase levels below 4000 units did so. All complications were successfully managed and there were no deaths. CONCLUSION: Determination of drainage fluid amylase levels is a simple and useful method for the prediction of pancreatic fistula formation and may help to plan appropriate management.

Enteral or parenteral feeding after total gastrectomy: prospective randomised pilot study.

OBJECTIVE: To compare the efficacy and cost of enteral and parenteral feeding after total gastrectomy. DESIGN: Prospective randomised open study. SETTING: University hospital, Finland. SUBJECTS: 29 patients undergoing curative total gastrectomy for gastric cancer. INTERVENTIONS: 13 patients were given early enteral feeding by nasojejunal tube and 16 patients parenteral nutrition by central venous catheter. MAIN OUTCOME MEASURES: Postoperative complications, duration of hospital stay, serum CRP and albumin concentrations, cost, and postoperative abdominal symptoms. RESULTS: One patient in the enteral feeding group discontinued the study on day 1. Oesophagojejunal leaks developed in one patient in each group. Infective complications occurred in 3 (23%) in the enteral group and 5 (31%) in the parenteral group. Serum CRP concentration on day six was lower in the enteral feeding group than in the parenteral feeding group (32 (16) g/L compared with 61 (41) g/L; p = 0.02). Enteral feeding was well tolerated. Diarrhoea developed earlier in the enteral than in the parenteral group (days 3-5 compared with 5-7, respectively) but there was a tendency to an increased risk of diarrhoea in the parenteral group. Parenteral feeding was more than four times as expensive as enteral feeding. CONCLUSION: Enteral nasojejunal feeding is safe and well tolerated after total gastrectomy. It is also cheaper than parenteral nutrition.

[Gastric resection and subtotal gastrectomy. Principles and updated surgical technique].

The Authors describe their last 10 years experience in gastric surgery. They report the results obtained in 12 gastric resections performed for complications following gastric and/or duodenal peptic ulcers, in 33 cases of total gastrectomies (34%), and 48 cases of subtotal gastrectomies (49%) for early and advanced cancer. The results lead to interesting conclusions: first of all achieving a wide jejunojejunostomy between the afferent and the efferent loop the problems related to gastric resection (as postoperative sequelae, dumping syndrome, reflux esophagitis, alkaline gastritis, etc.) are avoided. Problems regarding lymphadenectomy in patients submitted to subtotal gastrectomy (D2-D3) are then reported. After a brief history of gastric reconstruction following gastric resection the evolution in surgical techniques and the results obtained during the last 10 years are described. The good long term results allow to conclude that our strategy in gastric surgery ensures a good quality of life of the patients as well as a radical operation in case of gastric cancer.

Jejunal pouch with nerve preservation and interposition after total gastrectomy.

BACKGROUND/AIMS: In this paper, we describe operative technique details and our results with a modified technique for jejunal pouch formation and interposition after total gastrectomy, with an overall aim to achieve results superior to jejunal pouch and Roux-en-Y reconstruction, as reported in the literature. METHODOLOGY: Following total gastrectomy, the jejunum was divided approximately 20 cm distal to the ligament of Treitz. Marginal vessels were not divided in order to preserve the nerves in the 50 cm of distal jejunum which would be used for pouch construction. The pouch was constructed using a linear stapler (Endo GiA, United States Surgical Corp., Norwalk, Conn). A total of 15 gastric cancer patients underwent construction of a nerve-preserving jejunal pouch and interposition following total gastrectomy. RESULTS: None of the patients experienced postoperative complications due to pouch construction. Additionally, discomforts such as dumping or stagnation were not observed. Mild reflux esophagitis occurred in five of the 15 patients and was resolved by oral administration of camostat mesilate. Six months after surgery, the average patient's diet volume and body weight had gradually increased to 79% and 86%, respectively, of the presurgical levels. A dual phase, dual isotope radionucleid pouch emptying study was also performed six months after surgery. The intra-pouch RI retention rate was 47% for liquid food and 53% for solid food 120 minutes after intake. The emptying rate was slower for both solid and liquid food, as compared with healthy individuals. CONCLUSIONS: The pouch-emptying test demonstrated a satisfactory retention capacity and an acceptable emptying time as a gastric substitute. The patients who underwent gastric reconstruction with a nerve-preserving jejunal pouch with interposition have experienced a reasonably good quality of life.

Total gastrectomy: the influence of preserved duodenal transit and of pouch reconstruction on abdominal symptoms, nutrient assimilation, and medico-social functioning.

BACKGROUND/AIMS: The aim of this retrospective study was to establish whether patients with different reconstruction after total gastrectomy (duodenal bypass without pouch (subgroup Ia, n = 88); duodenal bypass with pouch (subgroup Ib, n = 27); continuous duodenal transit (subgroup II, n = 27)) differ concerning abdominal symptoms, nutrient assimilation, and medico-social functioning. METHODS: The 142 patients (49 females, 93 males; mean age 57.2 years, (95% confidence interval 55 to 59)) after potentially curative total gastrectomy for gastric malignancy 500 days earlier (mean: 95% confidence interval 334 to 666) were evaluated for abdominal symptoms, biochemical and haematological parameters, endoscopic findings, small intestinal bacterial overgrowth, oro-caecal transit time, objective signs of malassimilation, and the degree of medico-social functioning. RESULTS: There were no significant differences between the subgroups in any of the parameters examined. CONCLUSION: In this study, neither subjective nor objective patient data support preference for any single mode of the examined reconstructions after total gastrectomy. However, small patient numbers, unstandardised reconstruction procedures and a recruitment bias might influence these findings.

Gastric outlet loss and enterogastric reflux after gastrectomy.

The relationship of gastric secretion in response to a single injection of insulin and in response to a histamine infusion, before and after partial gastrectomy, was analysed in 58 patients. The aspirated gastric juice was corrected for gastric outlet loss and enterogastric reflux. Gastrectomy drastically reduced the stimulated gastric secretion by a similar proportion for the two secretagogues, thereby implying that antral gastrin plays no greater part in one than in the other. Gastric outlet losses were also reduced after gastrectomy, but as a fraction of gastric contents, both gastric outlet loss and enterogastric reflux more than doubled; the possible relationship of these findings to the aetiology of gastric ulcer is discussed.

Occurrence of non-gastric cancer in the digestive tract after remote partial gastrectomy: analysis of an Amsterdam cohort.

If peptic ulcer surgery favors the formation of carcinogenic N-nitroso compounds in the gastric remnant, an increased risk of cancer at sites in the gastrointestinal tract distant from the stomach might be predicted. To estimate the risk of carcinomas in the digestive tract, other than the stomach, occurring after partial gastrectomy, we analyzed an Amsterdam cohort of 2,633 post-gastrectomy patients operated on for benign disease between 1931 and 1960. Mortality in the study population was compared with the general Dutch population through person-year analysis. An excess mortality of biliary tract cancer (O/E:2.64; CL:1.32-4.72; p less than 0.01) and pancreatic cancer (O/E:1.65; CL:1.06-2.44; p less than 0.05) was found in males more than 5 years after surgery; females showed only an increased risk of pancreatic cancer in the first 5 years postoperatively (O/E:15.33; CL:1.85-55.43; p less than 0.01), probably due to misdiagnosis. All other non-gastric sites of the digestive tract carried no increased risk for cancer. In males, mortality due to colorectal cancer more than 5 years post-operatively was significantly decreased (O/E:0.58; CL 0.34-0.92; p less than 0.01). The excess mortality of biliary-tract and pancreatic cancer in males, which increases with the duration of post-operative interval, is consistent with a dose-response phenomenon. This study therefore supports the hypothesis that carcinogens are not only locally activated in the gastric remnant, but are hepatically excreted and initiate cancer in the biliary tree and pancreatic duct. Further exploration of this mechanism of carcinogenesis is warranted, since it may also explain the pathogenesis of pancreatic and biliary cancers in patients without gastrectomy.

[Oral glucose tolerance test with a mixture of oligosaccharides after partial gastrectomy (author's transl)].

Fourteen non-diabetic male patients undergoing partial gastrectomy for ulcer disease were investigated with oral glucose tolerance test using a 100 g mixture of oligosaccharides. Partial gastrectomy had been performed between 1 and 3 years ago. Compared to seven healthy male control subjects, patients had significant higher blood glucose levels at 30 and 60 min and a more rapid descent, so that at 120 and 180 min no differences were found between patients and control subjects. With the usual criteria (blood glucose levels at 120 and 180 min) the non-diabetic patients with partial gastrectomy showed normal test results.

Bone disorders following total gastrectomy.

Bone disorders following gastrectomy were studied by measuring absolute and relative bone mineral density of the Wards triangle, serum 1,25-(OH)2-D, alkaline phosphatase, and total serum calcium. The subjects were 20 males who had undergone total gastrectomy not more than three months previously (group A1). Seventeen of these patients were reviewed three years later (group A2). Absolute and relative bone density were significantly lower in group A2 than in A1 (0.52 +/- 0.011 g/cm2 versus 0.6 +/- 0.014 g/cm2, P < 0.01 and 85.5 +/- 1.4% age-matched control versus 95 +/- 1.3%, P < 0.01). 1,25-(OH)2-D was significantly lower in group A2 than in group A1 (14.3 +/- 0.97 pg/ml versus 20.6 +/- 1.02 pg/ml, P < 0.01). There was no difference in alkaline phosphatase and calcium serum concentration. The mean weight loss was 6.26 +/- 0.57% over the follow-up period, and weight loss correlated with absolute and relative bone density (r = -0.74, P < 0.01). There was a positive correlation between 1,25-(OH)2-D and absolute or relative bone density (r = 0.67, r = 0.62 and P < 0.01). These data suggest that bone density decrease has already occurred three years after total gastrectomy and is positively correlated to 1,25-(OH)2-D deficiency. As no differences in serum alkaline phosphatase and serum calcium concentration were found, these factors are of little value for the early detection of postgastrectomy bone disorders, whereas weight loss is a valuable screening parameter.

[Calcium and bone metabolism after gastrectomy].

Disturbances in calcium and bone metabolism after gastrectomy have long been recognized. It has been suggested that due to impaired calcium absorption after gastrectomy, serum calcium is decreased, being counter-regulated by parathyroid hormone release and 1,25-(OH)2-vitamin D formation. Both parathyroid hormone and 1,25-(OH)2-vitamin D are known to release calcium from bone, resulting in bone mass loss and increased fracture risk in some of the gastrectomized patients. No therapy is currently generally agreed on, although supplementation of vitamin D and calcium has been suggested repeatedly. A review on the current understanding of calcium and bone metabolism after gastrectomy is given.

Gastric tube reconstruction prevented esophageal reflux after proximal gastrectomy.

Although the standard operation for early cancer of gastric cardia is proximal gastrectomy followed by jejunal interposition, we recently reported a simple and useful technique for proximal gastrectomy with gastric tube reconstruction. The operative procedures included resection of the proximal two-thirds of the stomach, followed by anastomosis between the esophagus and gastric tube, using a circular stapler (Proximate ILS 25; Ethicon, Cincinnati, OH, USA). The gastric tube was about 20 cm long and 4 cm wide. The patient a 76-year-old man had no reflux symptoms such as heartburn, retrosternal pain, and regurgitation. Endoscopy showed no evidence of reflux esophagitis, including mucosal redness, erosion, and ulceration. Ambulatory 24-h pH monitoring indicated that the pH of the lower esophagus was between 6 and 8 when the patient was upright and between 5 and 7 when he was in the supine position. There were nine reflux episodes during the day, and no reflux episode while he was asleep. The duration of each reflux episode was less than 1 min, and the total reflux time was 1 min in the 12-h day (0.1%). These data indicate that reconstruction by gastric tube may prevent esophageal reflux in patients who have undergone proximal gastrectomy for early cancer of the gastric cardia.
