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.     

Long-term results of jejunal replacement of the esophagus

Since 1969, jejunal interpositions have been carried out in 19 patients for esophageal replacement. A segment of the upper jejunum was used to bridge the gap in the right thoracic cavity. The distal esophagus and its sphincteric mechanism was preserved in all but four patients, who had peptic strictures. Early postoperative complications such as total necrosis of the graft, perforation of the graft, and anastomotic leak developed in three patients (16%). There were no operative deaths but there were two later deaths (11%). We were able to follow 12 patients over a long term. Among these 12 patients there were two anastomotic strictures, one of which was dilated successfully by bouginage, and one marked redundancy of the jejunum which necessitated surgical correction. Both height and weight were lower than -2 SD on a Japanese standard growth curve in two patients who had anastomotic strictures. Transient stagnation of swallowed barium at the lower esophagus was the common finding; it was observed in seven cases (58%). Only three patients (25%) complained of occasional feelings of delay in swallowing. Stagnation with a mildly redundant jejunum was the common radiologic finding in these three patients. Reflux of the gastric content into the esophagus did not occur. All the patients, except one who still has dysphagia due to anastomotic stricture, can eat anything they wish at almost normal speed. These long-term results indicate that jejunal interposition with preservation of the lower esophagus is a recommendable procedure for esophageal replacement.     

Jejunal pouch interposition after pylorus-preserving gastrectomy.

BACKGROUND: To improve the quality of life of patients undergoing gastrectomy, a nerve-conserving jejunal pouch was interposed after pylorus-preserving gastrectomy (PPG) with vagal nerve preservation. We report the details of the operative technique and the outcome. METHODS: PPG with lymph node dissection was performed, preserving the hepatic, pyloric, and celiac branches of vagal nerve. The jejunum was cut approximately 20 cm distal to the ligament of Treitz. Marginal vessels were not divided in order to preserve the nerves in the jejunum that were used to construct the pouch. A linear stapler was used to perform a side-to-side jejunojejunostomy. A 12-cm-long pouch was formed by firing the stapler twice. The pouch was interposed between the residual parts of the stomach. Postoperatively, the patients were interviewed periodically. A dual-phase, dual-isotope radionucleid pouch-emptying study was performed 6 months after surgery. RESULTS: A total of 13 patients underwent the operation. No complication developed. During the first 6 months after surgery, the body weight of the patients was maintained at 91% of the preoperative level. The radioisotope retention rate for the combined pouch and residual stomach was 46% for liquid food and 76% for solid food 120 min after ingestion. The pattern of its emptying was similar to that in healthy individuals. CONCLUSIONS: The pouch-emptying test demonstrated a satisfactory retention capacity and acceptable emptying for the gastric substitute. A reasonably good quality of life has been obtained for patients undergoing PPG with interposition of a nerve-preserving jejunal pouch.     

Reconstruction modes following gastrectomy. Results of experimental and clinical controlled trials

Reconstruction modes following gastrectomy. Results of experimental and clinical controlled trials. In animal experiments four reconstruction methods following gastrectomy were compared: Roux-en Y reconstruction with (n = 33) and without pouch (n = 50) and isoperistaltic jejunum interposition with (n = 26) and without pouch (n = 55). The results were mostly influenced by the extent of esophagitis, documenting the reflux reduction by a pouch. Weight gain was slightly higher following jejunum interposition.Roux-en Y pouch reconstruction with jejunum interposition with pouch was compared in a randomized controlled trial. The additional operative effort of jejunum interposition did not achieve benefits in outcome. Therefore, Roux-en Y reconstruction should be advocated as standard reconstruction. The second randomized controlled trial compared Roux-en Y reconstruction with and without pouch. After more than three years, there was an advantage in life quality for patients with pouch indicating that patients with a favorable prognosis following gastrectomy should be reconstructed with a pouch.     

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.     

A simple biangulation stapling technique for large anastomoses in gastric surgery

We describe here a new technique for performing the large anastomosis between the jejunal pouch and the remnant stomach in patients undergoing proximal gastrectomy with jejunal pouch interposition. The biangulation method described in this report is a simpler technique than the existing triangulation anastomosis technique, requiring only two applications of a linear stapler. One row of staples forms the posterior wall of the anastomosis and the other forms the anterior wall. When used for jejunal pouch reconstruction after proximal gastrectomy in 12 cases of early gastric cancer, no evidence of anastomotic leakage or stenosis was apparent from barium meal studies or endoscopic examination. We find this biangulation technique to be a simple and safe procedure that is ideal for anastomoses of large diameter.     

Operative Technique on Nearly Total Gastrectomy Reconstructed by Interposition of a Jejunal J pouch with Preservation of Vagal Nerve, Lower Esophageal Sphincter, and Pyloric Sphincter for Early Gastric Cancer

Nearly total gastrectomy preserving the vagal nerve, the lower esophageal sphincter (LES), and the pyloric sphincter was developed as a function-preserving surgical technique to improve postgastrectomy disorders. In this paper, application criteria and technique are outlined, and postoperative quality of life was clinically investigated. Ten subjects who underwent this surgical operation (group A: 7 male and 3 female subjects at age 48 to 68 years with a mean age of 58.3 years) were interviewed to inquire about reflux esophagitis, dumping syndrome, and microgastria. Group A was compared with 20 cases of conventional total gastrectomy with D2 lymphadenectomy, excision of the lower esophageal sphincter (LES), total vagotomy, and single jejunal interposition (group B: 16 male and 4 female subjects at age 48 to 72 years with a mean age of 63.9 years). Included were cases with early cancer (M or SM1 of N0) localizing at the middle third and lower stomach, which was not applicable to endoscopic excision of gastric mucosa or partial gastric excision in M cancer, 2 cm or farther from the margin of the cancer to the esophagogastric mucosa cephalad junction and 3.5 cm or farther from the margin of the cancer to the pyloric caudad sphincter; in SM1 cancer, 4 cm or farther from the oral-side margin of the cancer to esophagogastric mucosa junction and 5.5 cm or farther from the anal-side margin of the cancer to the pyloric sphincter. In excision with lymph nodes, hepatic and celiac branches bifurcating from anterior and posterior trunks of the vagal nerve were preserved. To preserve LES, the esophagus was severed at the His angle at right angle to the longitudinal axis of the esophagus. The antrum was severed at 1.5 cm from the pyloric sphincter, preserving the arteria supraduodenalis. An alternative gaster was created as a 15-cm jejunal pouch with a 5-cm jejunal conduit for orthodromic peristaltic movement, using an automatic suture instrument to complete side-to-side anastomosis of folded jejunum with 1- to 1.5-cm long upper end of the pouch not anastomosed. The abdominal esophagus was mechanically anastomosed with a jejunal J pouch, and anastomosis of the pyloric antrum with a jejunal conduit was manually completed by stratum anastomosis. In group A, food ingestion per time could be taken the same as that of a healthy person, with no reflux esophagitis and dumping syndrome being noticed. Reflux esophagitis developed more significantly in group B than in group A (p < 0.05). In food ingestion per time, group B was significantly delayed compared with group A (p < 0.05). The present results suggested that the surgical technique proposed is a function-preserving gastric surgery appropriate to prevent postgastrectomy disorder of subjects.     

Improved quality of life with jejunal pouch reconstruction after total gastrectomy

BACKGROUND: There is increasing evidence that the effect of jejunal pouch reconstruction is satisfactory for reservoir function in several randomized control studies. However, these studies were performed in patients with advanced gastric cancer, where significant numbers of the patients died of disease recurrence. In order to exclude the influence of disease recurrence, we performed jejunal pouch reconstruction after total gastrectomy in patients with early gastric cancer in a randomized controlled study and investigated whether or not an improved quality of life (QOL) was observed with jejunal pouch reconstruction. METHODS: Fifty consecutive patients receiving total gastrectomy for early gastric cancer were prospectively divided into the Roux-en-Y reconstruction group without pouch (RY group) or the jejunal pouch reconstruction group (pouch group). Body weight, eating capacity, QOL assessment by gastrointestinal symptom rating scale (GSRS), nutritional parameters, endoscopical examination, 24-hour pH monitoring and Bilitec monitoring were evaluated at 3, 12, and 48 months after surgery. RESULTS: Jejunal pouch reconstruction provided the better QOL than Roux-en-Y reconstruction without pouch both at short-term and long-term periods in a randomized control study. Moreover, as a new finding, pouch reconstruction provided less bile reflux into the esophagus compared with Roux-en-Y reconstruction. CONCLUSIONS: Jejunal pouch reconstruction provided improvement of QOL in patients receiving total gastrectomy.     

Combination of a free jejunal flap and a Roux-en-Y colojejunostomy for reconstruction of esophageal stricture secondary to a distant blast injury: a case report

Pneumatic perforation of the esophagus caused by blast injury is very rare. Our patient presented with esophageal stricture in the context of a previous reconstruction of an esophageal rupture secondary to a distant air-blast injury. The ruptured esophagus was initially reconstructed with a left pedicled colon interposition in an antiperistaltic pattern. However, dysphagia developed 4 years later because of severe reflux-induced stenosis at the junction of the cervical esophagus and the left pedicled colon segment. A free isoperistaltic jejunal flap was performed to replace the cervical esophagus, with an anti-reflux Roux-en-Y colojejunostomy between the caudal segment of the left pedicled colon and the jejunum. The patient was discharged uneventfully 29 days later with smooth esophageal transit and no further reflux, as shown by scintigraphic scan. Esophageal reconstruction in an isoperistaltic pattern using a free isoperistaltic jejunal flap combined with an anti-reflux Roux-en-Y colojejunostomy has never been reported in the literature and appears to be an effective method to provide smooth passage of food and prevent restenosis of the esophagus.     

rho-Shaped anastomosis: a reconstruction of the alimentary tract after total gastrectomy.

One hundred sixty-four patients underwent total gastrectomy with a rho-shaped jejunal food pouch (rho loop) and roux-en-Y jejunojejunostomy. The rate of postoperative complications was very low (9.1 per cent), and the most important problem of anastomotic failure was never encountered. Only 4 of 164 patients (2.4 per cent) died within one month of surgery, and the causes of death were pneumonia (2 patients), cerebral hemorrhage (1), and ileus (1). The function of the newly constructed passage was estimated through an elaborate barium meal examination. The test revealed that the rho-shaped jejunal food pouch has adequate reservoir and mixing functions for ingested foodstuff. No reflux of barium meal into the esophagus was observed during the examination. In a follow-up study of the patients, only a few complained of symptoms of reflux esophagitis or dumping, but none of them needed any treatment.     

Canine intestinal myoelectric activity after total gastrectomy with jejunal interposition

Changes of intestinal myoelectric activities after total gastrectomy with jejunal interposition were studied in three conscious dogs. Under general anesthesia a total gastrectomy was performed and intestinal continuity was reestablished by a 15 cm jejunal segment interposed between the esophagus and the duodenum. Two electrodes were sown each to the serosal surface of the interposed segment of the jejunum, duodenum, and distal potion of the jejunum, respectively. After recovery from the surgery, the myoelectric activities were recorded for 8 to 12 hours during fasting and after feeding a 200 ml liquid meal. In each segment, total gastrectomy did not alter the initiation of the migrating myoelectric complex (MMC) during fasting. Total gastrectomy also changed neither the postprandial inhibition of the enteric MMC nor the induction of the fed myoelectric pattern after feeding. The way of MMC propagation along the small intestine, however, showed various patterns. Each of three segments generated its own MMCs. Some complexes migrated to the next segment or had an effect on initiating new MMCs of the next segment. Although MMCs occurring in the segment of the interposed jejunum hardly migrated to the adjacent duodenum, some jumped to the distal jejunum. These results suggest that there are no coordinated activities between the interposed jejunum and the duodenum after total gastrectomy with jejunal interposition.     

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 bad 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. The observed increase in body weight was 4.5±2.4 kg in 25 RY loop patients and 4.0±2.6 kg in the 9 IJI patients (not significant), with no significant benefit being observed in patients with newly created gastric “replacements.” It was concluded that (1) a technically correct and adequate reconstruction is not followed by significant levels of malnutrition; (2) a simple RY loop is the most suitable method in most instances for total gastrectomy for cancer; (3) an IJI is not justifiable on a routine basis; (4) additional pouches are of questionable value; and (5) omega loops are undesirable.     

Novel Operative Technique for Vagal Nerve- and Pyloric Sphincter-preserving Distal Gastrectomy Reconstructed by Interposition of a 5 cm Jejunal J Pouch with a 3 cm Jejunal Conduit for Early Gastric Cancer and Postoperative Quality of Life 5 Years after Operation

The importance of the vagal nerve and pyloric sphincter, the need for pouch reconstruction, and the ideal pouch volume are all matters of controversy. A novel operative technique for vagal nerve- and pyloric sphincter-preserving distal gastrectomy reconstructed by interposition of a 5 cm jejunal J pouch with a 3 cm jejunal conduit was developed as a function-preserving surgical technique to prevent postgastrectomy disorders. The application criteria and technique are outlined in this article. Postoperative quality of life was also investigated clinically. Twenty subjects who underwent this surgical operation (group A: 16 men and 4 women aged 41 to 70 years, mean age 59.5 years) were interviewed to inquire about postoperative gastrointestinal symptoms. These patients were compared with 44 others who underwent conventional distal gastrectomy with D2 lymphadenectomy (group B: 30 men and 14 women aged 43 to 73 years, mean age 62.6 years). Included were patients with early cancer [mucosal or submucosal 1 (SM1) cancer and no lymph node metastasis (N0)] in the middle or lower third of stomach (or both) who were either not eligible for endoscopic excision of gastric mucosa or for partial gastric excision in the mucosa = 3.5 cm or SM1 5.5 cm, or further in distance from the anal margin of the cancer to the pyloric sphincter. Cases in which the remnant stomach would become one-third or less of the original size were also applied. During excision with lymph nodes, the hepatic and celiac branches bifurcating from the anterior and posterior trunks of the vagal nerve were preserved. The antrum was severed 1.5 cm from the pyloric sphincter, preserving the arteria supraduodenalis. The substitute stomach was created as a 5 cm jejunal pouch with a 3 cm jejunal conduit for orthodromic peristaltic movement using an automatic suture instrument to complete a side-to-side anastomosis of the folded jejunum. The anal side of the gastric remnant was manually anastomosed with the jejunal J pouch, and anastomosis of the pyloric antrum with the jejunal conduit was manually completed by stratum anastomosis. Postoperatively, the procedure in group A alleviated gastrointestinal symptoms such as appetite loss, epigastric fullness, reflux esophagitis, early dumping syndrome, body weight loss, endoscopic reflux esophagitis, and endoscopic gastritis in the remnant stomach, postprandial stasis of the substitute stomach, and postgastrectomy cholecystolithiasis better than in group B. The results suggest that the proposed technique is a function-preserving gastric operation appropriate for preventing postgastrectomy disorder.     

Linear stapling forms improved anastomoses during esophagojejunostomy after a total gastrectomy

BACKGROUND: Circular stapling devices are commonly used to form esophagojejunal anastomoses after total gastrectomy. However, the technique has potential problems with placement of the purse-string suture and insertion of the anvil of the instrument. METHODS: We describe an improved technique for esophagojejunostomy by functional end-to-end anastomosis with linear stapling devices. RESULTS: Three patients with gastric cancer underwent this procedure after total gastrectomy. No anastomotic leakage or clinical evidence of stenosis was encountered. The maximum diameters of the anastomoses, evaluated by radiography with barium at 6 months after surgery, were 3.5 cm and 4.0 cm in 2 patients. Endoscopic examination revealed clear lines of anastomosis with a straight continuity between the distal esophagus and the jejunum. CONCLUSIONS: Our improved technique for esophagojejunostomy by functional end-to-end anastomosis with two linear staplers is a convenient, safe and reliable procedure that is independent of the width of the esophagus and the depth of the esophageal hiatus.     

A Step-Wise Approach to Total Laparoscopic Gastrectomy with Jejunal Pouch Reconstruction: How and Why We Do It

Laparoscopic gastrectomy (LG) is a safe alternative compared to open gastrectomy for cancer. To increase the uptake of minimally invasive approaches and facilitate their analysis and improvement a stepwise approach is warranted. This study describes our technique and experiences total laparoscopic gastrectomy (TLG) with jejunal pouch reconstruction for gastric cancer. Technical modifications throughout the years were described. In patients with anastomotic leakage, the CT-scan and reoperation report were reviewed to identify the location and cause of the leak. A total of 47 patients who underwent laparoscopic total gastrectomy with extracorporeal jejunal pouch reconstruction and stapled circular esophagojejunostomy from May 2007 to August 2015 were prospectively analyzed. A stepwise approach of 10 steps was designed based on video and case analysis. Median operation time was 301 (148–454) minutes and median blood loss was 300 (30–900) milliliters. Anastomotic leakage occurred in six (12.8 %) patients; additionally, one (2.12 %) jejunal-pouch staple line leak was identified. An important modification in our technique was a purse-string suture around the anvil of the circular stapler to prevent esophageal mucosa to slip away. After this modification, the leakage rate was reduced to 7 % in the last 15 procedures. In conclusion, TLG with jejunal pouch reconstruction is a feasible procedure in a selected group of patients. Our stepwise approach and technique may help surgeons to introduce jejunal pouch reconstruction during laparoscopic gastrectomy in their center.

Regular scintigraphic measurements of food transit following different types of reconstruction after total gastrectomy.

HYPOTHESIS: Ideal reconstruction after gastrectomy should ensure that the patient has a sufficiently large enteric reservoir to accommodate normal meals. Little is known about the transit of food after different methods of stomach reconstruction. The hypothesis of this trial was that food transit after gastrectomy is delayed by a pouch reconstruction compared with reconstructions without a pouch. DESIGN: Prospective. SETTING: University hospital. PATIENTS AND METHODS: A total of 27 patients underwent an interposition of a jejunal loop between the esophagus and the duodenum with (n = 19) or without (n = 8) a 7- or 15-cm proximal pouch reconstruction. Standardized scintigraphic measurements were performed to evaluate the food transit at fixed postoperative times. MAIN OUTCOME MEASURE: Scintigraphically measured food transit time. RESULTS: The food transit time 1 year postoperatively was significantly prolonged in patients with the 15-cm pouch in comparison with those with the 7-cm pouch and those without a pouch reconstruction (P = .005, P = .012). Patients with a pouch reconstruction tended to have better eating habits. CONCLUSIONS: Our results confirm the hypothesis and suggest that interposition of a large 15-cm jejunal pouch can lead to a prolonged food transit time with enteric reservoir function resulting in better patient nutritional status.     

Jejunal pouch to avoid stricture after esophagojejunostomy with circular stapler.

BACKGROUND: Anastomotic stricture is one of the most common problems in esophagojejunostomy using the end-to-end anastomosing (EEA) instrument (Auto Suture Co, Norwalk, CT) after total gastrectomy. To alleviate the stricture, several methods, such as incision to the scar, balloon dilatation, and steroid injection are available. To avoid stricture, the jejunal pouch may allow use of a larger EEA than Roux-en-Y (ReY) reconstruction does. STUDY DESIGN: A total of 45 patients underwent curative total gastrectomy and esophagojejunostomy with jejunal pouch construction (27 patients) or ReY (18 patients), using the EEA. The effects of jejunal pouch construction with a large EEA on avoidance of stricture and benefit to nutritional status were investigated by comparing it with the ReY in terms of postoperative morbidity, postprandial symptoms, and nutritional parameters (serum protein, serum albumin, body weight). RESULTS: EEA28 or larger could be used in 25 patients in the pouch group and 8 patients in the ReY group (p < 0.05). Stricture developed in one patient in the pouch group and in four patients in the ReY group (p < 0.05). Postprandial symptoms were experienced less frequently (p < 0.05) in the pouch group than in the ReY group. When stricture and symptoms were analyzed according to the size of EEA, they occurred more frequently (p < 0.05) in the patients with EEA25 than those with EEA28 or EEA31. No significant differences were evident in nutritional parameters. CONCLUSIONS: The choice of jejunal pouch technique allowed the use of a larger EEA than that of ReY reconstruction, resulting in avoidance of anastomotic stricture and postprandial symptoms, though little benefit in nutritional status was evident to the patients after total gastrectomy.     

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.
