Postoperative evaluation of the jejunal pouch reconstruction following proximal and distal gastrectomy for cancer

BACKGROUND/AIMS: To evaluate the efficacy of the jejunal pouch reconstruction following subtotal proximal and distal gastrectomy, a retrospective study examining the postoperative condition of patients who underwent different methods of reconstruction after gastrectomy for cancer was undertaken. METHODOLOGY: Various parameters indicative of postoperative function were evaluated at one year postoperatively, and two major groups were examined. The "proximal gastrectomy" group was composed of patients who underwent either 1) proximal gastrectomy with an interposed jejunal pouch (PG-pouch), 2) proximal gastrectomy with simple jejunal interposition (PG-inter), or 3) total gastrectomy with simple jejunal interposition (TG). The "distal gastrectomy" group was composed of patients who underwent either 4) distal gastrectomy with an interposed jejunal pouch (DG-pouch), 5) distal gastrectomy with simple jejunal interposition (DG-inter), or 6) distal gastrectomy with Billroth 1 reconstruction (B-1). RESULTS: Volume of meal intake was better preserved and the incidence of abdominal symptoms were less frequent in the PG-pouch and DG-pouch groups. In the PG-inter, DG-inter and DG-pouch groups, none of the patients experienced heartburn or had endoscopic findings consistent with reflux esophagitis, while 2 patients (20.0%) in the PG-pouch group complained of heartburn with evidence of reflux esophagitis on endoscopy. Increase in blood acetaminophen level was milder in both the PG-pouch and DG-pouch groups, signifying improved gastric emptying. CONCLUSIONS: The jejunal pouch interposition following proximal and distal gastrectomy seems to confer clinical benefit in terms of postoperative function, especially in the form of meal intake, abdominal symptoms, and gastric emptying. The side effect of an improved reservoir may be the incidence of reflux esophagitis seen in 2 patients in the PG-pouch group.     

Serious complications after a proximal gastrectomy with a jejunal pouch interposition for gastric cancer

Proximal gastrectomy with jejunal interposition is a common surgical method in Japan, because the procedure has been shown to give a better post-operative quality of life. Some complications are associated with it. However, esophageal candidiasis and linear marginal ulcer along the gastrojejunal anastomosis after the surgical method has never previously been reported. We herein report a case of a patient who developed serious complications after proximal gastrectomy with jejunal interposition. A 68-year-old man underwent proximal gastrectomy with a jejunal pouch interposition for reconstruction for type 1 gastric cancer. Twenty-three months after the procedure, he complained of dysphagia and epigastric pain. Esophagogastroduodenoscopy showed esophageal candidiasis. The patient improved symptomatically following antifungal medication with fluconazole. Eleven months later, the patient developed severe pneumonia. In subsequent days, a melena episode occurred. Esophagogastroduodenoscopy revealed a linear marginal ulcer along three-fourths of the gastrojejunal anastomosis. The ulcer was drug resistant. The patient died of respiratory failure. Jejunal pouch interposition after a proximal gastrectomy can be associated with significant complications. Further studies are required to identify the best condition of the procedure.     

Jejunal interposition helps prevent reflux gastritis

BACKGROUND/AIMS: Jejunal interposition after distal gastrectomy is reported to prevent both duodenogastric reflux and rapid gastric emptying. However, comparing primary reconstruction with this procedure and Billroth-I in terms of clinical evaluation by the same surgeon is rare. In this study, the benefit of this procedure was retrospectively evaluated as compared to the Billroth-I method. METHODOLOGY: Of 30 patients with early gastric cancer located at the middle third of the stomach, 15 underwent distal gastrectomy with jejunal interposition and the other 15 underwent Billroth-I gastrectomy by the same surgeon. Isoperistaltic jejunal interposition measuring 10-12 cm was used. All the anastomoses without jejunojejunostomy were performed using auto-suture staplers. Assessment of postoperative symptoms and functions was performed one year after surgery. RESULTS: The mean operation time was significantly longer after jejunal interposition (p < 0.01). No serious complications occurred in either group, and the hospital stay after operation was also similar. There were no significant differences in terms of postoperative symptoms, food intake, and recovery of body weight. The incidence of bile regurgitation and reflux gastritis was very low or zero in the jejunal interposition group, which indicated differences (p < 0.05, p < 0.01, respectively). Reflux esophagitis was not found in jejunal interposition, but two patients after Billroth I showed grade B esophagitis. As regards gastric emptying, the retention capacity was very poor and there was no significant difference between the two groups. CONCLUSIONS: Jejunal interposition after distal gastrectomy was superior to the Billroth-I procedure in terms of reflux gastritis prevention. However, dumping syndrome and rapid gastric emptying were not prevented.     

A novel operative technique on proximal gastrectomy reconstructed by interposition of a jejunal J pouch with preservation of the vagal nerve and lower esophageal sphincter.

BACKGROUND/AIMS: This article describes the surgical techniques and postoperative status for proximal gastrectomy reconstructed by interposition of a jejunal J pouch with preservation of the vagal nerve and lower esophageal sphincter. METHODOLOGY: We have performed a new technique for reducing postgastrectomy sequelae such as reflux esophagitis, early dumping syndrome, and microgastria in early gastric cancer located in the proximal third of the stomach. The technique consists of proximal gastrectomy with preservation of the hepatic, pyloric, celiac branch of the vagal nerve, and abdominal esophagus (lower esophageal sphincter), and reconstruction by interposition of a jejunal J pouch. To reserve pyloric function, pyloroplasty can be omitted by preservation of the pyloric branch from the vagal nerve. To restore loss of reservoir function, the reconstruction is performed with an interposed jejunal J pouch. Sacrifice of the mesenteric arcades is kept to a minimum to preserve the autonomic nerve and blood flow in the mesentery. RESULTS: All of the patients who underwent this operation were able to eat an adequate amount of food at 6 months after surgery and they were satisfied with their postoperative status. And that, we have not experienced postgastrectomy disorders such the dumping syndrome and reflux esophagitis. CONCLUSIONS: Therefore, this method is useful for preventing the postoperative disorders in patients with early gastric cancer located in the proximal third of the stomach.     

Evaluation of reconstruction after proximal gastrectomy: prospective comparative study of jejunal interposition and jejunal pouch interposition

BACKGROUND/AIMS: To prevent various distresses after proximal gastrectomy, reconstruction by interposed jejunal pouch has been advocated as an organ-preserving surgical strategy to ensure favorable quality of life for the patients. METHODOLOGY: Proximal gastrectomy was performed in 9 patients with gastric cancer in the upper third of the stomach. Four patients were randomly selected for reconstruction by jejunal pouch interposition (JPI group), while 5 had reconstruction by jejunal interposition (JI group). The patients who underwent JPI and JI were followed up to evaluate resumption of normal diet, change in body weight, and clinical symptoms. RESULTS: The JPI group showed a significant dietary advantage. Three months after surgery, JPI patients could eat more than 80% of the volume of their preoperative meals, whereas JI patients ate less than 50%. The percentage of postoperative body weight loss was higher in the JI group than in the JPI group because the volume of the remnant stomach was more adequate in the latter. Moreover, it was easier to enter the remnant stomach and duodenum for endoscopic fiberscopy in the JPI group for the treatment of hepato-biliary pancreatic disease. CONCLUSIONS: JPI is an effective method for preservation of gastric function after proximal gastrectomy.     

Jejunal pouch interposition with an antiperistaltic conduit as a pyloric ring substitute after standard distal gastrectomy: a comparison with the use of an isoperistaltic conduit

BACKGROUND/AIMS: We performed jejunal pouch interposition with a short antiperistaltic conduit as a pylorus substitute after gastrectomy for gastric cancer and compared the outcome with an isoperistaltic conduit. METHODOLOGY: After a standard distal gastrectomy and lymph node dissection, a 15-cm-long pouch was formed using 3 linear staples (Endo-GIA) and interposed between the residual stomach and duodenum. The distal jejunal limb was made into a 3-cm-long isoperistaltic conduit in the isoperistaltic group (n = 17), and the proximal jejunal limb was made into a 3-cm-long antiperistaltic conduit in the antiperistaltic group (n = 8). Postoperatively, the patients were interviewed periodically to document any complaints. A dual-phase, dual-isotope radionuclide gastro-pouch-emptying study was performed 1 and 6 months after surgery. RESULTS: None of the patients developed postoperative complications and showed discomforts of dumping, stasis or reflux esophagitis. The dietary volume and body weight of patients gradually increased in both groups after 6 months. The combined radioisotope retention rate for the pouch and residual stomach was 31% for liquid food and 35% for solid food in the isoperistaltic group after 120 min, and 41% and 57%, respectively, in the antiperistaltic group. The pattern and emptying rate for solid food in the antiperistaltic group were more similar to those in healthy individuals than in the isoperistaltic group. CONCLUSIONS: The gastro-pouch-emptying test in the antiperistaltic group demonstrated acceptable emptying for a pyloric ring substitute. A reasonably good quality of life has been obtained for patients having an antiperistaltic jejunal conduit.     

Marginal ulcer on the jejunum after proximal gastrectomy by jejunal interposition

Marginal ulcer after proximal gastrectomy has never been previously reported, despite that this procedure preserves the fundic gland area of the stomach, which secretes gastric acid. In this report, we describe a patient who developed a marginal ulcer on the oral side of the gastrojejunal anastomosis after proximal gastrectomy by jejunal interposition. This case serves as a reminder that gastric acid secretion of the remnant stomach must be carefully monitored after proximal gastrectomy in gastric cancer surgery.     

Role of pyloroplasty after proximal gastrectomy for cancer

BACKGROUND/AIMS: The necessity of pyloroplasty as a drainage procedure after proximal gastrectomy remains controversial in terms of the postoperative quality of life. The aim of this retrospective study was to evaluate whether pyloroplasty is necessary after proximal gastrectomy. METHODOLOGY: Thirty-five patients who underwent proximal gastrectomy with jejunal interposition between 1993 and 2000 were studied. They were divided into two groups: Group A, jejunal interposition without pyloroplasty (n=17); Group B, jejunal interposition with pyloroplasty (n=18). The subjects were interviewed and examined to assess their symptoms, food intake and body weight at 6, 12, and 24 months after the operation. Endoscopy and a radioisotope gastric emptying test were performed one year postoperatively. RESULTS: A low incidence of epigastric fullness, nausea, and vomiting and a high frequency of patients with greater than 80% of pre-illness food intake were found in Group B. A high recovery of bodyweight was also achieved in Group B. On the other hand, a high incidence of reflux gastritis or bile regurgitation was found in Group B. Gastric emptying was significantly delayed in Group A. CONCLUSIONS: Pyloroplasty as a drainage procedure after proximal gastrectomy is necessary in terms of the clinical symptoms, dietary intake, recovery of body weight, or gastric emptying.     

Esophagogastrostomy reconstruction after limited proximal gastrectomy

BACKGROUND/AIMS: Recent advances in diagnostic techniques have led to the detection of an increasing number of early gastric cancers in the upper third of the stomach. The objective of this study was to determine the most appropriate surgical treatment for these cancers. METHODOLOGY: The clinicopathologic characteristics of 35 patients with early gastric cancer in the upper third of the stomach who underwent three different types of gastrectomies were reviewed retrospectively from hospital records between January 1992 and August 1999. RESULTS: Patients undergoing limited proximal gastrectomy with esophagogastrostomy reconstruction had shorter operation times and less blood loss than those for patients undergoing total gastrectomy or proximal gastrectomy with jejunal interposition. No lymph node metastasis was identified in any of these patients. Heartburn due to reflux esophagitis was seen in a few patients of each group, but they were successfully treated by antacids. The extreme reduction in food intake volume was more frequently experienced in patients with total gastrectomy than those with both proximal gastrectomies. When mortality due to other disease was excluded, all patients survived without recurrence. CONCLUSIONS: A limited proximal gastrectomy with esophagogastrostomy reconstruction decreased surgical risk and realized preservation of maximal function.     

Functional outcomes according to the size of the gastric remnant and type of reconstruction following open and laparoscopic proximal gastrectomy for gastric cancer

Background/Aims: We compared functional outcomes between different types of reconstruction following open or laparoscopic 1/2- or 2/3-proximal gastrectomy for gastric cancer. Methodology: Resection and reconstruction were performed by one of the following 6 methods, depending on the depth of cancer invasion and the date of the procedure relative to introduction of laparoscopic proximal gastrectomy: open proximal 2/3-gastrectomy with jejunal interposition (2/3PG-int, n=7), open proximal 1/2-gastrectomy with jejunal interposition (1/2PG-int, n=5), laparoscopic proximal 1/2-gastrectomy followed by double tract reconstructions with small (3cm) jejunogastrostomy (L1/2 PG-DT(S), n=19) and laparoscopic proximal 1/2-gastrectomy followed by double tract reconstructions with large (6cm) jejunogastrostomy (L1/2PG-DT(L), n=10). Open total gastrectomy with jejunal interposition (TG, n=12) and laparoscopic total gastrectomy with Roux-en-Y reconstruction (LTG, n=14) represented control procedures. Results: Comparison of postoperative/preoperative body weight ratios and food intake ratios revealed better preservation among patients with a larger remnant stomach and with easy flow of food into the remnant stomach (the 1/2PG-int and L1/2PG-DT(L) groups). Conclusions: Better functional outcomes were observed in patients with a large remnant stomach and with easy flow of food into the remnant stomach regardless of whether they underwent open or laparoscopic procedures.     

Function-preserving gastrectomy for gastric cancer in Japan

Surgery used to be the only therapy for gastric cancer, and since its ability to cure gastric cancer was the focus of attention, less attention was paid to functionpreserving surgery in gastric cancer, though it was studied for gastroduodenal ulcer. Maki et al developed pylorus-preserving gastrectomy for gastric ulcer in 1967. At the same time, the definition of early gastric cancer(EGC) was being considered, histopathological investigations of EGC were carried out, and the validity of modified surgery was sustained. After the development of H2-blockers, the number of operations for gastroduodenal ulcers decreased, and the number of EGC patients increased simultaneously. As a result, the indications for pylorus-preserving gastrectomy for EGC in the middle third of the stomach extended, and various alterations were added. Since then, many kinds of function-preserving gastrectomies have been performed and studied in other fields of gastric cancer, and proximal gastrectomy, jejunal pouch interposition, segmental gastrectomy, and local resection have been performed. On the other hand, from the overall perspective, it can be said that endoscopic resection, which was launched at almost the same time, is the ultimate function-preserving surgery under the current circumstances. The current function-preserving gastrectomies that are often performed and studied are pylorus-preserving gastrectomy and proximal gastrectomy. The reasons for this are that these procedures that can be performed with systemic lymph node dissection, and they include three important elements:(1) reduction of the extent of gastrectomy;(2) preservation of the pylorus; and(3) preservation of the vagal nerve. In addition, these operations are more likely to be performed with a laparoscopic approach as minimally invasive surgery. Of the above-mentioned three elements, reduction of the extent of gastrectomy is the most important in our view. Therefore, we should try to reduce the extent of gastrectomy if curability of the gastric cancer can still be achieved. However, if we preserve a wider residual stomach in functionpreserving gastrectomy, we should pay attention to the development of metachronous gastric cancer.     

Suture line recurrence in the jejunal pouch after curative proximal gastrectomy for gastric cancer: report of two cases

We report two patients with suture line recurrence in the jejunal pouch after curative proximal gastrectomy for gastric cancer. The first patient was a 60-year-old asymptomatic woman with gastric cancer (T2N0M0) after curative proximal gastrectomy with jejunal pouch interposition. She had to undergo a second resection for suture line recurrence in the jejunal pouch 12 months later. On examination of the resected specimen, histological examination revealed a moderately differentiated adenocarcinoma, which was similar to that of the primary tumor. The second patient was a 74-year-old man who was also diagnosed as having locoregional recurrences in the jejunal pouch after a curative proximal gastrectomy with an S-shaped pouch for gastric cancer (T2N0M0). Histological examination of the resected specimen revealed moderately differentiated adenocarcinoma, which had a similar histopathology to that of the primary tumor. During the first procedure, the jejunal pouch was formed using several disposable devices and the end-to-side esophagojejunostomy was performed with another circular stapler to avoid contamination through surgical instruments. Exfoliated cancer cells that may have detached from the primary tumor during the surgical procedures could have contributed to local recurrence along the longitudinal suture line of the pouch.     

Anti-reflux pouch-esophagostomy after proximal gastrectomy with jejunal pouch interposition reconstruction

Reflux esophagitis is a serious postoperative complication for patients undergoing gastrectomy. We designed a new jejunal pouch-esophagostomy to prevent reflux after proximal gastrectomy. After proximal gastrectomy, ajejunal segment about 17 cm long was folded. Side-to-side jejuno-jejunostomy was made using a linear stapler with 100-mm staples along the length at the anti-mesenteric side. A 10-cm-longjejunal pouch with a 7-cm-long apical bridge was made. Esophago-jejuno end-to-side anastomosis (pouch-esophagostomy) was made with circular stapler at the right anterior wall the apical bridge. We add "partial posterior fundoplication" like wrapping using the apical bridge of the jejunal pouch. Patients with this new anti-reflux anastomosis showed no reflux on barium meal study even in the right anterior oblique deep Trendelenburg's position. Jejunal pouch reconstruction with partial posterior wrapping provides a satisfactory result with regard to preventing reflux esophagitis.     

Full robot-assisted gastrectomy with intracorporeal robot-sewn anastomosis produces satisfying outcomes

AIM:To evaluate the feasibility and safety of full robotassisted gastrectomy with intracorporeal robot handsewn anastomosis in the treatment of gastric cancer.METHODS:From September 2011 to March 2013,110consecutive patients with gastric cancer at the authors’institution were enrolled for robotic gastrectomies.According to tumor location,total gastrectomy,distal or proximal subtotal gastrectomy with D2 lymphadenectomy was fully performed by the da Vinci Robotic Surgical System.All construction,including Roux-en-Y jejunal limb,esophagojejunal,gastroduodenal and gastrojejunal anastomoses were fully carried out by the intracorporeal robot-sewn method.At the end of surgery,the specimen was removed through a 3-4 cm incision at the umbilicus trocar point.The details of the surgical technique are well illustrated.The benefits in terms of surgical and oncologic outcomes are well documented,as well as the failure rate and postoperative complications.RESULTS:From a total of 110 enrolled patients,radical gastrectomy could not be performed in 2 patients due to late stage disease;1 patient was converted to laparotomy because of uncontrollable hemorrhage,and1 obese patient was converted due to difficult exposure;2 patients underwent extra-corporeal anastomosis by minilaparotomy to ensure adequate tumor margin.Robot-sewn anastomoses were successfully performed for 12 proximal,38 distal and 54 total gastrectomies.The average surgical time was 272.52±53.91 min and the average amount of bleeding was 80.78±32.37 mL.The average number of harvested lymph nodes was 23.1±5.3.All specimens showed adequate surgical margin.With regard to tumor staging,26,32 and 46 patients were staged asⅠ,ⅡandⅢ,respectively.The average hospitalization time after surgery was 6.2 d.One patient experienced a duodenal stump anastomotic leak,which was mild and treated conservatively.One patient was readmitted for intra-abdominal infection and was treated conservatively.Jejunal afferent loop obstruction occurred in 1 patient,who underwent re-operati     

Gastric emptying after segmental gastrectomy for early cancer in the middle part of the stomach.

BACKGROUND/AIMS: We evaluated the quality of life and gastric emptying in patients who had undergone a segmental gastrectomy to treat early gastric cancer in the middle part of the stomach. METHODOLOGY: Thirty patients were considered in this study. Their mean age was 65.5 years (range: 44-83). All of the patients were free from recurrence of their cancer in the follow-up period. This ranged from 5 to 50 months (mean 30). Patients were interviewed at regular intervals to assess their quality of life and to note particular complaints. The upper gastrointestinal tract was assessed endoscopically. A gastric emptying study was performed at 3, 6, and 12 months after surgery. The meal used in this dual-phase study had solid and liquid phases. For the solid phase, 74 MBq of 99mTc sulfur colloid was injected into an egg, which was then hard-boiled. For the liquid phase, 18.5 MBq of (111)In-diethyltriaminopenta acetic acid (DTPA) were mixed into 150 ml of a commercial, elentary liquid diet. RESULTS: Three months after surgery, the patients' main complaints were gastric stasis (25%), heartburn (8%) and belching (8%). The patients gradually became asymptomatic following surgery. Fifty-nine percent were asymptomatic at the 3-month follow-up, 84% at 6 months, and 92% at 12 months. There was no evidence of reflux esophagitis or gastritis after the 3-month follow-up. One patient developed a complicated duodenal ulcer. Initially, the patients all had prolonged gastric emptying of the dual phase meal, compared to normal individuals. The T1/2 for liquid meal emptying was 87+/-18 min at 3 months, 77+/-20 min at 6 months and 50+/-5 min at 1 year after surgery. The last value is the same as for healthy individuals. Solid meal emptying was still prolonged, with an emptying rate of 36+/-9.7% at 2 hours, one year after surgery. CONCLUSIONS: Segmental gastrectomy patients experienced prolonged gastric emptying in the early post-operative period. This improved in the first year after surgery. The quality of life for patients who underwent segmental gastrectomy has been reasonably good in the follow-up period to date.     

Efficacy of endoscopic surveillance of the upper gastrointestinal tract following distal gastrectomy for early gastric cancer

BACKGROUND/AIMS: How endoscopy can be used in the follow-up of the upper gastrointestinal tract in patients who underwent gastrectomy for early gastric cancer remains unclear. METHODOLOGY: Two-hundred and ten patients (137 males and 73 females, aged at initial gastrectomy 27-86, average age 56.5) were followed in the present study. Results of follow-up endoscopy of all patients, pathologic diagnoses of secondary tumors and interval between gastrectomy and detection of secondary tumor were reviewed. Cumulative incidence rate of second tumors in the upper gastrointestinal tract was then analyzed. RESULTS: Secondary tumor was observed by follow-up endoscopy in 7 patients including two gastric, one esophageal, one duodenal carcinoma and 3 gastric adenomas. The interval between initial gastrectomy and diagnosis of secondary tumor ranged from 20 to 71 months (average 51.7 months). All carcinomas were early stage and localized within the mucosa. Three patients with secondary cancer were successfully treated by endoscopic mucosal resection. The cumulative incidence rate of secondary cancer in the gastric remnant, esophagus and duodenum at six years after initial gastrectomy was 1.0, 0.8 and 0.5%, respectively. The overall incidence rate of secondary tumors of the upper gastrointestinal tract at six years after distal gastrectomy was 4.1%. CONCLUSIONS: The present findings indicate that annual follow-up endoscopy of the upper gastrointestinal tract after gastrectomy for early gastric cancer can be introduced to detect carcinoma at an early stage, thus improving the survival rate of gastrectomy patients.     

A case of esophageal cancer with mesojejunal lymph node metastasis after total gastrectomy

A 56-year-old man was diagnosed with esophageal cancer by upper gastrointestinal endoscopy for examination of dysphagia. The patient had undergone total gastrectomy and jejunal interposition 4 years previously for a gastric cancer at the pT1N0M0 stage according to the UICC-TNM classification. Enhanced CT findings revealed a 3-cm-diameter mass located near the superior mesenteric artery. We conducted subtotal esophagectomy associated with partial jejunectomy including mesojejunectomy. The mass was histologically diagnosed to be mesojejunal lymph node metastasis from esophageal cancer. Mesojejunal lymph node metastasis from esophageal cancer developing after total gastrectomy has been reported in only three cases including ours. The present lymph node metastases may have occurred via the newly developed lymphatic drainage route through the esophagojejunostomy, and this metastatic lymph node can be considered the regional lymph node. Therefore, resection of the interposed jejunal limb with mesojejunectomy may be rational in surgery on esophageal cancer developing after total gastrectomy.     

Long-term results after surgery for gastric cancer with or without jejunal reservoir: results of surgery for gastric cancer in Kanta-Häme central hospital in two consecutive periods without or with jejunal pouch reconstruction in 1985-1998

Background: Gastric cancer still has a disease-specific 5-yr survival less than 30% and an overall survival of about 15%. The quality of life of patients who undergo gastrectomy is poor owing both to the severity of the disease itself and to the mutilation of the upper gastrointestinal channel after the reconstruction. Therefore, the combination of a jejunal pouch with gastrectomy has been claimed to improve the life quality and nutritional status of these patients. Aim: To assess the clinical results after surgery for gastric cancer in two consecutive periods with or without jejunal-pouch reconstruction. Methods: 271 consecutive patients referred for surgery for gastric cancer in 1985–1991 (116 patients) and in 1992–1998 (155 patients) in Kanta-H?me central hospital were retrospectively analyzed regarding their disease, mode of surgery, and the immediate and long-term results. In the former observation period gastrectomy was performed with Roux-en-Y esophagojejunostomy without a reservoir, and in the latter period this procedure was combined with a jejunal reservoir. The data were collected from patient journals and from the death certificate obtained from the National Centre of Statistics in Finland. Results: During the study period the incidence of cancer in the cardia increased among the surgical patients from 13.1 to 26.7% (p <0.05). Despite this proximal migration, the cancer-specific 5-yr survival remained practically unchanged during the two study periods, 29.4% and 32.2% (NS). During the period of jejunal-pouch reconstruction there were non-significant increases of the incidences of local recurrence (from 18.9% to 26.5%), of immediate postoperative anastomotic fistulae (from 0.9% to 4.5%) as well as of the immediate mortality (from 2.6% to 3.7%) (NS for each). Conclusions: Despite proximal migration of gastric cancer and the application of a jejunal reservoir, the long-term as well as the immediate results after curative surgery (i.e., D2-gastrectomy) for gastric cancer have remained relatively unchanged. The jejunal-pouch reconstruction with the present technique after gastrectomy can therefore be safely applied.     

Total gastrectomy reconstructed by interposition of a jejunal J pouch with preservation of hepatic vagus branch and lower esophageal sphincter for T2 gastric cancer without lymph node metastasis

BACKGROUND/AIMS: In order to improve postgastrectomy disorders of patients with T2 (MP or SS) gastric cancer without lymph node metastasis, which mainly locates in the middle third of stomach, we have performed a total gastrectomy preserving both hepatic vagus branches and the lower esophageal sphincter as a function-preserving surgical procedure. METHODOLOGY: In the present study, the application criteria and points of the technique are outlined, and postoperative quality of life is clinically investigated. Twenty-four subjects who underwent this surgical operation (group A; 16 men and 8 women subjects aged 46 to 73 years, mean age 62.2 years) were interviewed regarding appetite, weight loss, reflux esophagitis, dumping syndrome, and microgastria. Cholelithiasis following total gastrectomy was also checked by abdominal ultrasonography. Group A was compared with 26 cases of conventional total gastrectomy with D2 lymphadenectomy, excision of lower esophageal sphincter, total vagotomy, and single jejunal interposition (B group; 19 men and 7 women subjects aged 42 to 75 years, mean age 64.8 years). Application criteria of the technique: Included were cases with T2 cancer of N0 mainly localizing at the middle-third of the stomach which was 4 cm or further in distance from the oral-side margin of the cancer to the esophagogastric mucosa junction. Points of the technique: In lymphadenectomy, hepatic branches of the vagal nerve only preserved. To preserve lower esophageal sphincter, the abdominal esophagus was severed at the level of His angle to the longitudinal axis of the esophagus. Substitute stomach was created as a 15-cm jejunal pouch with a 5-cm-long jejunal conduit for isoperistaltic movement. RESULTS: In group A the food ingestion rate was significantly greater than that of group B (P<0.001) at 6 months and 2.0 years after operation, with no reflux esophagitis or dumping syndrome being noticed at 2.0 years after operation. In group B, loss of appetite 2.0 years after operation was significantly higher than that in group A (P<0.01). In addition, symptomatic reflux esophagitis (heartburn, dyspepsia, regurgitation) developed more significantly in group B than in group A (P<0.05). For food ingestion per time, group B was significantly delayed compared with group A (P<0.05). Body weight loss in group B was significantly higher than that in group A (P<0.01). Postgastrectomy cholelithiasis was detected significantly more in group B than in group A (P<0.05). CONCLUSIONS: These results suggested that the surgical technique proposed is safe and leads to a satisfactory symptomatic and nutritional result, and that this procedure is a function-preserving gastric surgery appropriate to prevent postgastrectomy disorders of subjects for T2 gastric cancer without lymph node metastasis, mainly located in the middle-third of stomach.     

Critical analysis of the treatment of gastric ulcer by proximal gastric vagotomy

In the surgical treatment of gastric ulcer (G,U,), the same techniques have been employed as have been used in duodenal ulcer (D.U.). This correspondence also holds true with superselective vagotomy and proximal gastric vagotomy (P.G.V.). The technique was primarily indicated in the treatment of D.U. and had very exciting preliminary results, above all owing to its reduced morbidity both immediately and late after surgery, and to its almost null mortality. With a view to analyzing the results of the use of P.G.V. in the treatment of gastric ulcer, thirteen patients were operated upon who were bearers of G.U. not associated with D.U. nor prepyloric ulcer. There were no operating accidents or immediate post-operative complications, nor was there any mortality. In the post-operative period following lasting an average of 17.7 months, we observed the clinical manifestation of the ulcer and symptoms accompaning the operation in addition to performing endoscopy on all of the patients. Eight patients were absolutely asymptomatic after surgery; one had slight dysphagia that diminished about 3 months after P.G.V. Three patients had recurrence of the symptoms of ulcer and one complained of intense epigastric fullness, vomting, weight loss, and a crisis of diarrhea. Radiologic and endoscopic examinations showed that this last patient had hypotonia and marked gastric stasis that were corrected surgically by means of antrectomy and the reconstitution of GI tract by the BI technique, with good results. In three patients endoscopy showed postoperative recurrence of the G.U., one of whom is assymptomatic with the clinical treatment; the other two were submitted to antrectomy with BI anastomosis in one and a 2/3 gastrectomy with BI reconstruction in the other. The cure of the lesion in 23% of the cases in the post-operative follow-up lasting an average of 17.7 months permits us henceforward to contra-indicate the P.G.V. used per se for the treatment of G.U.
