Total gastrectomy for gastric carcinoma: a retrospective study of different procedures and assessment of a new technique of gastric reconstruction

Dorsal Track Control (DTC): A Modified Surgical Technique for Atraumatic Handling of the Distal Esophagus in Esophagojejunostomy

Surgical therapy for adenocarcinoma of the esophagogastric junction II requires distal esophagectomy, in which a transhiatal management of the lower esophagus is critical. The ‘dorsal track control’ (DTC) maneuver presented here facilitates the atraumatic handling of the distal esophagus, in preparation for a circular-stapled esophagojejunostomy. It is based on a ventral semicircular incision in the distal esophagus, with an intact dorsal wall for traction control of the esophagus. The maneuver facilitates the proper placement of the purse-string suture, up to its tying (around the anvil), thus minimizing the manipulation of the remaining esophagus. Furthermore, the dorsally-exposed inner wall surface of the ventrally-opened esophagus serves as a guiding chute that eases anvil insertion into the esophageal lumen. We performed this novel technique in 21 cases, enabling a safe anastomosis up to 10 cm proximal to the Z-line. No anastomotic insufficiency was observed. The DTC technique improves high transhiatal esophagojejunostomy.

Jejunal pouch reconstruction after total gastrectomy is associated with better short-term absorption capacity and quality of life in early-stage gastric cancer patients

Background

No consensus exists regarding the best reconstruction style after total gastrectomy (TG). Roux-en-Y oesophagojejunostomy is a simple option for gastrointestinal tract reconstruction. Recently, jejunal pouch reconstruction has been suggested as an appropriate approach. We compared the postoperative outcomes of the two surgical approaches using a well-characterized cohort of gastric carcinoma patients.

Methods

A total of 60 patients who underwent TG were divided into two groups according to the reconstruction style. Both groups were compared regarding patient characteristics, perioperative data and quality of life (QoL), which was assessed using the Spitzer QoL index (QLI) and Visick grade. The incidence of long-term surgery-related complications, including reflux oesophagitis, dumping syndrome, and retention syndrome, was also compared to evaluate postoperative restoration.

Results

Both study groups were comparable with respect to general patient characteristics. No mortality or no significant differences in surgery-related data were found except in the operation time. Compared to Orr Roux-en-Y reconstruction, pouch reconstruction was associated with a longer procedure time, a lower incidence of dumping/retention syndrome and better QoL parameters (p < 0.05).

Conclusion

In this study, jejunal pouch reconstruction after TG was superior to the traditional Roux-n-Y oesophagojejunostomy with respect to improved dietary intake and QoL.

Evaluation of the safety and efficacy of esophagojejunostomy after totally laparoscopic total gastrectomy using a trans-orally inserted anvil: a single-center comparative study

BACKGROUND

Although laparoscopic surgery is frequently performed for the treatment of gastric cancer, laparoscopic total gastrectomy is not widely performed because of its technical difficulty. Since December 2007 we have performed esophagojejunostomy after totally laparoscopic total gastrectomy (TLTG) in more than 110 cases in our institution by using a circular stapler with a trans-orally inserted anvil. We performed a single-center comparative study to evaluate the safety and efficacy of esophagojejunostomy using a trans-orally inserted anvil in patients who underwent TLTG for the treatment of gastric cancer.

METHODS

In the present study, we examined 329 patients with gastric cancer who underwent esophagojejunostomy using a circular stapler after total gastrectomy. Data on the clinicopathological features, operative time, amount of intraoperative blood loss, and incidence of anastomosis-related complications among the surgical groups were obtained by reviewing the medical records, which were then analyzed.

RESULTS

Approximately 67% of the patients were men, and the average patient age was 64.0 years (range 26-93 years). In addition, 166 (50.5%) and 163 (49.5%) patients underwent open and laparoscopic surgery, respectively. Leakage following esophagojejunostomy was noted in 7 (4.2%) of 166 patients who underwent total gastrectomy with open laparotomy, and 0 of 46 patients who underwent laparoscopic-assisted total gastrectomy (LATG). However, only 2 (1.7%) of 117 patients who underwent TLTG using a trans-orally inserted anvil exhibited leakage following esophagojejunostomy. Anastomotic stenosis of the esophagojejunostomy was observed in 5 (3.0%) of 166 patients who underwent total gastrectomy with open laparotomy, 2 (4.3%) of 46 patients who underwent LATG, and 2 (1.7%) of 117 patients who underwent TLTG using a trans-orally inserted anvil.

CONCLUSIONS

We believe that esophagojejunostomy using a trans-orally inserted anvil after TLTG for gastric cancer is a safe and useful surgical procedure.

Efficacy of NiTi Hand CAC 30 for jejunojejunostomy in gastric cancer surgery: results from a multicenter prospective randomized trial

BACKGROUND

Although a novel technique for the performance of intestinal sutureless anastomosis using a compression device has recently been investigated, it has not yet received widespread acceptance. We performed a multicenter prospective randomized trial in order to determine the clinical efficacy of the NiTi Hand CAC 30, a type of compression anastomosis clip (CAC), for jejunojejunostomy in gastric cancer surgery.

METHODS

Forty-seven patients from 6 institutions, who were diagnosed with gastric adenocarcinoma, were enrolled; these patients were randomized to a CAC group and a hand-sewn (control) group. Three patients dropped out for various reasons, and results for 44 patients were finally analyzed. The CAC group consisted of 20 patients, and there were 24 patients in the control group.

RESULTS

Anastomosis time, the primary endpoint of this trial, was shorter in the CAC group than in the control group (P < 0.001). However, total operation times (P = 0.055) did not differ. All reconstructions were completed by Roux-en-Y anastomosis, and the complication rates of the two groups did not differ (P = 0.908); however, jejunojejunostomy leakage occurred in two patients in the CAC group.

CONCLUSIONS

Our prospective multicenter clinical trial showed that the use of the NiTi Hand CAC™ 30 for jejunojejunostomy in gastric cancer surgery was feasible and could reduce anastomosis time. However, considering that there were two cases of leakage, extended use of the NiTi Hand CAC™ 30 should be carefully applied.

Early dumping syndrome and reflux esophagitis prevention with pouch reconstruction

BACKGROUND

Total gastrectomy causes numerous disorders, such as reflux esophagitis, dumping syndrome, malabsorption, and malnutrition. To minimize the consequences, different variants of reconstruction are performed. The aim of our study is the comparison of two reconstructive methods: the standard Roux-en-Y and a new modality of pouch interposition, preduodenal-pouch interposition. This study aims to investigate the advantage of bile reflux prevention and to reduce symptoms of dumping syndrome after 3- and 6-mo follow-up.

MATERIALS AND METHODS

A total of 60 patients were divided in two groups: (A) 30 patients with Roux-en-Y reconstruction, and (B) 30 patients with the preduodenal-pouch (PDP) type of reconstruction. Endoscopic examination and endoluminal jejunal limb pressure measurements were performed. Scintigraphic measurements of half-emptying time were performed to evaluate meal elimination in the context of reflux esophagitis and early dumping syndrome. The Japan Society of Gastrointestinal Surgery has provided guidelines with which to classify the symptoms of early dumping syndrome. Patients were followed up for periods of 3 and 6 mo after the surgery.

RESULTS

Our study groups did not differ with regard to the level of reflux esophagitis (P = 0.688). Average values of pressure at 10 and 15 cm below the esophago-jejunal junction were significantly lower in the PDP group (P < 0.001). Elimination of the test meal between two groups was not significant (P = 0.222). Evaluation of early dumping syndrome symptoms revealed a significant reduction among PDP patients after 3 and 6 mo.

CONCLUSION

Our study showed significant superiority of the new pouch reconstruction over the standard Roux-en-Y approach in the treatment of early dumping syndrome.

Assessment of tissue-engineered stomach derived from isolated epithelium organoid units

OBJECTIVE

Isolated stomach epithelial organoid units developed on biodegradable polymers were transplanted to assess the feasibility of a tissue-engineered stomach.

BACKGROUND

Despite recent advances in reconstruction techniques, total gastrectomy is still accompanied by various complications. An alternative treatment would be a tissue-engineered stomach, which replaces the mechanical and metabolic functions of a normal stomach.

METHODS

Stomach epithelial organoid units isolated from neonatal rats were seeded onto biodegradable polymers. The constructs implanted into the omenta of adult rats were harvested for examination at designated times. Nine rats underwent a second operation for anastomosis.

RESULTS

The constructs resulted in cyst-like formations showing vascularized tissue with neomucosa lining the lumen. The surface morphology as assessed using scanning electron microscopy was similar to that of a native stomach. Immunohistochemical staining for alpha-actin smooth muscle and gastric mucin indicated the presence of a smooth muscle layer and a well-developed gastric epithelium, respectively. The luminal surface of the anastomosed tissue-engineered stomach was well-covered with epithelium.

CONCLUSIONS

Epithelium-derived stomach organoid units seeded on biodegradable polymers and transplanted into donor rats were shown to vascularize, survive, and regenerate into complex tissue resembling native stomach. Anastomosis between the units and native small intestine may have the potential to stimulate epithelial growth. This research may provide insight into new approaches to alleviate complications following total gastrectomy.

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.

Initial Assessment of A Tissue Engineered Stomach Derived From Syngeneic Donors in a Rat Model

The objective of this study is to assess the feasibility of creating a tissue engineered stomach using isolated stomach epithelium organoid unit from syngeneic adult donors and a biodegradable polymer scaffold in a rat model. Despite recent advances in reconstruction techniques, total gastrectomy is still accompanied by various complications. As an alternative treatment, a tissue engineered stomach that replaces the mechanical and metabolic functions of a normal stomach is proposed. Stomach epithelium organoid units were isolated from syngeneic adult rats and seeded onto biodegradable polymers. These constructs were implanted into the omenta of recipient adult rats. All constructs were harvested for histologic and immunohistochemical examination at designated time points. Cyst-like structures were formed that showed the development of vascularized tissue with a neomucosa. Immunohistochemical staining for alpha-actin smooth muscle, gastric mucin, and proton pump indicated the presence of a smooth muscle layer and gastric epithelium, as well as the existence of parietal cells of the stomach mucosa, respectively. Epithelium derived stomach organoid units seeded on biodegradable polymers were transplanted in donor rats and have been shown to vascularize, survive, and regenerate into complex tissue resembling a native stomach. These initial results are encouraging, and studies are currently underway to further assess this approach.

Long-term follow-up of patients with jejunal pouch reconstruction after total gastrectomy. A randomized prospective study

BACKGROUND

Fifty-one patients were operated on during 1988-1992 and randomized after total gastrectomy to one of two reconstruction types. Twenty patients with jejunal pouch reconstruction and 14 patients with Roux-en-Y reconstruction (67% of all) survived at least 3 years after total gastrectomy. We studied symptoms, eating capacity, and nutrition in these patients during the clinical follow-up; 21 patients were assessed by mail questionnaire 8 years after total gastrectomy.

METHODS

Postoperative symptoms, number of meals, and eating capacity were assessed by standard questionnaire during 3 years' follow-up. Weight loss and nutritional laboratory variables were measured, and upper intestinal endoscopy with biopsy was performed during the follow-up. Eight years after the operation symptoms, ability to eat, and number of meals consumed were studied by means of a mail questionnaire.

RESULTS

Three years postoperatively dumping (64% compared with 10%, P < 0.05) and early satiety (86% compared with 5%, P < 0.05) were commoner in the Roux-en-Y group. In the pouch group eating capacity was better (96% of normal compared with 67%, P < 0.05), and the patients ate fewer meals per day (mean, 2.7 versus 5.3, P < 0.05) at 3 years. Mean weight loss at 3 years was 9.9 kg in the Roux-en-Y group compared with 1.5 kg in the pouch group (P < 0.05). 25 (OH) vitamin D concentration tended to be higher in the pouch group (47.3 nmol/l compared with 33.9 nmol/l). In the Roux-en-Y group serum alkaline phosphatase activity increased significantly during the 3 postoperative years (from mean 163 U/l to 248 U/l, P < 0.01) and tended to be higher (248 U/l compared with 216 U/l in the pouch group). None of the patients developed oesophagitis or pouchitis during the follow-up. One patient developed a bezoar in the pouch 5 years after gastrectomy.

CONCLUSIONS

Pouch reconstruction after total gastrectomy is associated with diminished postoperative symptoms, better eating capacity, and decreased weight loss compared with Roux-en-Y reconstruction. Jejunal pouch reconstruction is thus the recommended surgical method after total gastrectomy.

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.

An improved technique for a stapled transabdominal esophagojejunostomy

BACKGROUND

In the performance of a stapled transabdominal esophagojejunostomy there are two main technical problems involved and related to a difficult surgical exposure. One is the placement of the purse-string suture and the second is the insertion of the anvil of the circular intraluminal stapler into the distal esophagus.

METHODS

These technical difficulties can be overcome by opening just the anterior wall of the esophagus at the anastomosis level, leaving the posterior wall intact.

RESULTS

The integrity of the posterior wall avoids retraction of the mucosa, allowing the esophagus to remain opened for the placement of a through and through purse-string suture under direct vision. It also acts as a conduit for the insertion of the anvil of the circular intraluminal stapler.

CONCLUSIONS

The technique described herein avoids stay sutures, purse-string instruments, and forceful instrumental dilatation of the distal esophagus, making these very important operative steps much easier, safer, and more reliable.

Jejunal pouch reconstruction after total gastrectomy for cancer. A randomized controlled trial

OBJECTIVE

The authors determined the optimum reconstruction procedure after total gastrectomy in terms of the quality of life of the patients.

SUMMARY BACKGROUND DATA

Gastric replacement with various enteric reservoirs has been used to improve the postprandial symptoms and nutrition of patients after total gastrectomy. However, the effect of each is uncertain because no prospective randomized studies have been conducted.

METHODS

A randomized controlled trial was conducted to compare the usefulness of the three reconstruction procedures of simple Roux-en-Y (RY; N = 10), pouch and Roux-en-Y (PR; N = 10), and pouch and interposition (PI; N = 10). In each subject, the postprandial symptoms, food intake in a single meal, body weight, serum nutritional parameters, and emptying time of the gastric substitute were evaluated.

RESULTS

The PR group showed significantly greater food intake in a single meal than the RY and PI groups, and greater weight recovery than the PI group. A gastric emptying test also revealed satisfactory retention capacity and emptying time of the gastric substitute in the PR group.

CONCLUSIONS

Pouch and Roux-en-Y reconstruction is the most useful of the three procedures for improving the postoperative quality of life. In patients with pouch and interposition reconstruction, the clinical assessment was quite poor, even though it is a physiologic route.

Experiences with the linear cutter technique for performing Roux-en-Y anastomosis following total gastrectomy

The use of stapling devices for performing gastro-intestinal anastomosis has recently gained wide acceptance. In fact, since 1991, we have been using linear cutter devices for performing the Roux-en-Y anastomosis, transection of the duodenum, and closure of the jejunal stump (except following esophagojejunostomy), and are no longer employing hand-sewn procedures. In this report, the linear cutter technique used after total gastrectomy is described and the differences in anastomotic leakage, morbidity, operating time, and reconstruction time are evaluated in comparison with those following hand-sewn anastomoses. A total of 22 patients undergoing total gastrectomy within a 2-year period were randomized into two groups of 11, to have reconstruction performed by either a stapled or hand-sewn Roux-en-Y anastomosis. One patient from the stapled group died of acute myocardial infarction 6 days after the operation. Anastomotic leakages from the esophagojejunostomy region occurred in 18% of the patients in the stapled group, but fortunately no leakage was apparent from the Y-anastomosis when the linear cutter technique was used. The most obvious significance was the short mean reconstruction time in the stapled group of 19.1 +/- 3.56 min (P < 0.01) being 31 min shorter than that of the hand-sewn group (n = 11). Thus, we proposed that the linear cutter technique is a safe technique for performing anastomosis following total gastrectomy, which would significantly reduce the reconstruction time.

Total gastrectomy for cancer: is reconstruction or a gastric replacement reservoir essential?

Malnutrition is a frequently observed complication of total gastrectomy. Does the mode of reconstructing the alimentary tract bear part of the responsibility? We assessed our experience from January 1975 to 1992 to analyze this issue. A series of 64 total gastrectomy patients [40 men, 24 women; aged 59 +/- 11 (SD) years] were considered. Preoperative and periodic follow-up evaluations were prospectively documented: upper gastrointestinal series, endoscopic examination, complete blood count, serum and liver biochemistry profiles, serum proteins, tranferrin, serum iron and calcium, iron-binding capacity, oral glucose tolerance test, ultrasonography or computed tomography, actual and ideal body weight and performance (AJCC/UICC) assessments. Symptoms were classified by means of Cuschieri's scoring system. Esophageal mucosal changes (edema, hyperemia, erosions, ulcerations) were documented on endoscopy. There were 36 of 58 operative survivors who had no evidence of tumor recurrence and were available for long-term evaluation (12-132 months). An RY loop had been constructed in 25 patients, 5 with a Hunt pouch; 9 had an isoperistaltic jejunal interposition (IJI), 4 with a Kock pouch; and 2 had a Braun loop. A 60 to 70 cm long jejunal limb was always utilized. Statistical analyses were obtained by means of the Student t-test and the equality of medians test. Progressive malnutrition was observed in patients with the Braun (omega) loops, both patients displaying persistent esophagitis and dietary restrictions. Both recovered ideal body weight after remedial surgery that transformed the omega loop into an RY loop. Both RY and IJI loops effectively prevented alkaline esophagitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Long-term clinical and endoscopic assessment after total gastrectomy for cancer

Progressive malnutrition has been reported as a long-term consequence of total gastrectomy (TG), possibly related to the mode of reconstructing the intestine. In reviewing our personal experience (1975-Sept. 91), we attempted to correlate the reconstructive technique used with the subsequent course of the patient. A consecutive series of 62 TGs (59 adenocarcinomas, 3 lymphomas) in 38 males and 24 females 59 +/- 11 (m Mean +/- SD) years old was reviewed. Preoperative and "follow-up" evaluations, including upper gastrointestinal series and/or endoscopic examination, complete blood count, serum and liver biochemistry profiles, serum iron and plasma transferrin, oral GTT, USG or CT scan, actual and ideal body weight (IBW Life Extension Institute of New York), and "performance status" assessments, were prospectively documented. The follow-up symptoms were classified as per Cuschieri's scoring system. The endoscopic esophageal mucosa assessments were documented as well. Among 56 patients surviving operation, 34 were available, without tumor recurrence, for long-term (12-132 months) evaluation. A Roux-en-Y loop reconstruction had been performed in 23, 5 with a Hunt-Lawrence pouch; an isoperistaltic, esophagoduodenal, jejunal interposition (IR) was performed in 9, 4 with a Kock pouch; and an omega loop reconstruction was performed in 2. A 60-70-cm-long jejunal limb was always utilized.(ABSTRACT TRUNCATED AT 250 WORDS)

Early gastric cancer: 46 cases treated in one surgical department

Forty six consecutive patients with early gastric cancer were treated between 1970 and 1990. The proportion of cases of early gastric cancer increased significantly (p < 0.01) from 1% of all cases in the first five year period to 15% in the last five year period, because of greater awareness of the condition and more widespread use of endoscopy. There were 33 men and 13 women, of median age 69 years (range 38-86). Most patients (91%) presented with symptoms indistinguishable from those of peptic ulceration. The median duration of symptoms was four months (range 0.1-36 months). All 46 patients were treated surgically. Three patients (6.5%) died after operation and a further 10 (22%) suffered postoperative complications. None of the surviving patients has been lost to follow up and 25 have been followed up for a minimum period of five years. Five year survival by life table analysis was 98%. These findings suggest that in Britain in the 1990s, as in Japan, it may be possible to diagnose an increasing proportion of patients with gastric cancer at a relatively early pathological stage, when most patients can be cured by radical surgical resection with lymphadenectomy.

Improving survival in gastric cancer: review of operative mortality in English language publications from 1970

In this review of English language publications from 1970, operative mortality following surgery for gastric cancer has been analysed. Operative mortality has declined in series reporting operations in successive decades to 1970, 1980 and 1990. Series reporting patients having surgery for gastric cancer in the decade to 1990 show a mean operative mortality rate of 7.8 per cent (median 4.6 per cent). This improvement may have contributed to the declining mortality rates for gastric cancer in the face of unchanging surgical workload. Results of operations for gastric cancer should be reported in a standard manner.

Jejunal pouch reconstruction after total gastrectomy for cancer: experience in 29 patients

The experience with interposed jejunal pouch after total gastrectomy for cancer in 29 patients is reviewed. There were two postoperative deaths (7 per cent) due, respectively, to myocardial infarction on day 5 and massive haemorrhage from the splenic vein on day 14. Anastomotic leaks, all from the proximal anastomosis, were encountered in three patients (11 per cent). These consisted of one minor clinical leak in a stapled anastomosis and two radiological leaks from hand-sutured anastomoses. Obstruction of the pouch or its conduit by recurrent tumour was not observed in any patient, including those who died from metastatic disease. There was one instance of benign stenosis of the distal anastomosis to the duodenum which required revisional surgery. The symptomatic assessment in the long-term surviving patients was good except for mild oesophagitis due to bile reflux in five patients. Body-weight was maintained and adverse nutritional consequences were not observed.

Total gastrectomy and oesophagojejunostomy with linear stapling devices

When performing total gastrectomy and oesophagojejunostomy with a circular stapling device two disadvantages are obvious; firstly, a purse-string suture is needed, and secondly the instrument can be extremely difficult to introduce if the oesophagus is narrow, so that the risk of rupture is substantial. We therefore developed the following technique. When the specimen is attached only to the oesophagus, and the Roux-en-Y loop has already been divided with a linear stapling device, a small incision is made on the back wall of the oesophagus and antimesenterically 6 cm distal to the cut end of the Roux-en-Y loop. The two forks of the GIA or the PLC 50 instrument are introduced into the oesophagus and jejunum, and the two organs are brought together at the hiatus. The instrument is closed and fired. The residual opening is closed with a linear stapler which also includes the front wall of the oesophagus. With a knife, the oesophagus and excessive amounts of tissue are trimmed away, and the oesophagojejunostomy is completed. Fifteen patients (median age 67 years) had a postoperative hospital stay of 10 days (range 8-45 days) after this operation. Leakage occurred in one patient and one patient died. The anastomosis took 12 min to perform (range 8-20 min). Three reoperations were needed: intestinal obstruction, leakage and a negative exploration. The median width of the oesophagojejunal anastomosis 6 months after operation was 32 mm (range 27-40 mm). Oesophagojejunostomy performed with two linear staplers allows a quick and reliable anastomosis independent of oesophageal lumen size and a time-consuming purse-string suture.

Nutritional effects of postgastrectomy reconstruction: a clinical evaluation

To evaluate the nutritional benefits of a jejunal pouch vs. esophagojejunostomy following total gastrectomy, we reviewed 24 consecutive cases of total gastrectomy: 14 males and 10 females, 39 to 85 years of age (mean 66.6 y.) undergoing 9 jejunal pouches (JP) and 15 Roux-en-Y esophagojejunostomy (EJ). Indications for surgery included 15 adenocarcinomas, 3 lymphomas, 1 leiomyoma, and 5 hemorrhagic gastritis. The operative mortality was 12.5%. One JP patient was lost to follow-up. The mean survival for EJ was 13.3 months and for JP 36 months. Total gastrectomy resulted in persistent weight loss and hypoalbuminemia, and the creation of a jejunal pouch did not seem to improve significantly the nutritional status following total gastrectomy.

Malignant tumors of the stomach

A variety of malignancies may arise from the stomach, but the vast majority are adenocarcinomas. Despite a steady decline in the incidence of gastric carcinomas in the United States over the last 50 years, the overall prognosis remains dismal. Early diagnosis and an aggressive surgical approach provide the best hope of improving the outlook for patients with gastric cancer.

Healing of esophagojejunal anastomoses after experimental total gastrectomy. A comparative study using manually sutured or stapled anastomoses

In construction of the eosphagojejunostomy after total gastrectomy, the EEA stapled (US Surgical Corporation, Norwalk, CT) and the two-layer interrupted 3-0 Dexon anastomoses are compared concerning the radiological appearance, breaking strength, circulation, and collagen concentration. Thirty female pigs were used. After total gastrectomy and Roux-en-Y preparation, the pigs were randomized to achieve sutured or stapled anastomoses. 141Ce-labeled microspheres were used for measurements of anastomotic blood flow. After the pigs were killed, the breaking strength of the anastomosis was recorded, the collagen content determined, and an anastomotic index calculated comparing two perpendicular diameters in the anastomosis and 5 cm above. Breaking strength, leakage frequency, and anastomotic index were the same in the two groups. One week after surgery, there was a significant increase in anastomotic circulation (p less than 0.05) in both the sutured and the stapled anastomoses compared to controls. Collagen increased equally with time in the two groups (p less than 0.01). The stapled esophagojejunostomy was faster to perform (20 min) than the sutured (28 min) (p less than 0.05).

Nutritional effects of postgastrectomy reconstructions

To compare the nutritional effects of two modes of reconstruction after total gastrectomy, a Hunt-Lawrence pouch was constructed in five mongrel dogs, whereas five other dogs had a simple Roux-Y esophagojejunostomy performed. Total body weight, daily food intake, serum albumin values, and intestinal absorption of carbohydrates, fats, and amino acids were evaluated in both groups over a period of 3 months. All values decreased postoperatively when compared with the preoperative values; however, there was no significant difference between the two groups. This study suggests that there is no nutritional benefit from a Hunt-Lawrence pouch over a simple Roux-Y esophagojejunostomy after total gastrectomy.

Long term evaluation of a reservoir jejunal interposition with an isoperistaltic conduit in the management of patients with the small stomach syndrome

The results of reservoir jejunal interposition in 9 patients with severe symptoms of the small stomach syndrome have been reviewed after a median follow-up period of 4.2 years (range 6 months to 10 years). Objective assessment of improvement in terms of weight gain, haemoglobin and serum albumin levels was obtained in all the patients but only 3 have reached and maintained their ideal weight. No patient has been rendered symptom free, but significant improvement of the post-cibal symptoms was observed in 7 patients. The most common residual symptoms have been heartburn and postprandial epigastric fullness. These have improved with metoclopramide therapy.
