Benign esophageal stricture after thermal injury treated with esophagectomy and ileocolon interposition

Thermal injuries of the esophagus are rare causes of benign esophageal stricture, and all published cases were successfully treated with conservative management. A 28-year-old Japanese man with a thermal esophageal injury caused by drinking a cup of hot coffee six months earlier was referred to our hospital. The hot coffee was consumed in a single gulp at a party. Although the patient had been treated conservatively at another hospital, his symptoms of dysphagia gradually worsened after discharge. An upper gastrointestinal endoscopy and computed tomography revealed a pin-hole like area of stricture located 19 cm distally from the incisors to the esophagogastric junction, as well as circumferential stenosis with notable wall thickness at the same site. The patient underwent a thoracoscopic esophageal resection with reconstruction using ileocolon interposition. The pathological findings revealed wall thickening along the entire length of the esophagus, with massive fibrosis extending to the muscularis propria and adventitia at almost all levels. Treatment with balloon dilation for long areas of stricture is generally difficult, and stent placement in patients with benign esophageal stricture, particularly young patients, is not yet widely accepted due to the incidence of late adverse events. Considering the curability and quality-of-life associated with a long expected prognosis, we determined that surgery was the best treatment option for this young patient. In this case, we decided to perform an esophagectomy and reconstruction with ileocolon interposition in order to preserve the reservoir function of the stomach and to avoid any problems related to the reflux of gastric contents. In conclusion, resection of the esophagus is a treatment option in patients with benign esophageal injury, especially in cases involving young patients with refractory esophageal stricture. In addition, ileocolon interposition may help to improve the quality-of-life of patients.     

Effects of vagus nerve preservation and vagotomy on peptide YY and body weight after subtotal gastrectomy

AIM: To investigate the relationship between the function of vagus nerve and peptide YY_3-36 and ghrelin levels after subtotal gastrectomy.METHODS: We enrolled a total of 16 patients who underwent subtotal gastrectomy due to gastric cancer. All surgeries were performed by a single skilled surgeon. We measured peptide YY_3-36, ghrelin, leptin, insulin, growth hormone levels, and body weight immediately before and one month after surgery.RESULTS: Vagus nerve preservation group showed less body weight loss and less increase of peptide YY_3-36 compared with vagotomy group (-5.56 ± 2.24 kg vs -7.85 ± 1.57 kg, P = 0.037 and 0.06 ± 0.08 ng/mL vs 0.19 ± 0.12 ng/mL, P = 0.021, respectively). Moreover, patients with body weight loss of less than 10% exhibited reduced elevation of peptide YY_3-36 level, typically less than 20% [6 (66.7%) vs 0 (0.0%), P = 0.011, odd ratio = 3.333, 95% confidence interval (1.293, 8.591)].CONCLUSION: Vagus nerve preservation contributes to the maintenance of body weight after gastrectomy, and this phenomenon may be related to the suppressed activity of peptide YY_3-36.     

New method for jejunal pouch interposition reconstruction after distal gastrectomy

BACKGROUND/AIMS: Recently pouch reconstruction has been reported to improve quality of life and functional results after surgery for gastric cancer. Although jejunal pouch reconstruction after distal gastrectomy has favorable results for patients' quality of life, it is complicated and takes a long time to complete. We developed a new technique using a linear stapling device to avoid this problem. METHODOLOGY: The duodenum and the jejunum are simultaneously divided with a 100-mm linear stapler 0.5 cm distal to the pyrolus ring and 20 cm distal to the ligament of Treitz, respectively. A 100-mm linear stapler is introduced into two approximated segments of the jejunum through two small stab wounds 10 cm and 15 cm distal to the stump, respectively, and side-to-side anastomosis is performed along the antimesenteric borders. The anterior wall of the pouch is cut along the prospective line of anastomosis with the gastric remnant. The anterior wall of the stomach is cut along the planned suture line having a length similar to that of the pouch. The posterior walls of the stomach and the jejunal pouch are placed back-to-back on the planned anastomotic line. End-to-end posterior anastomosis between the gastric remnant and the jejunal pouch is simultaneously performed with gastrectomy using a 100-mm linear stapler. End-to-end anterior anastomosis is created by hand. RESULTS: This technique has been used in 4 patients, and there have been no complications related to the pouch or anastomoses. Mean operative time was 255 +/- 37 min (range: 205-290 min). CONCLUSIONS: Shortening of operative time can be attributed to adoption of end-to-end posterior anastomosis between the stomach and the jejunal pouch using the linear stapling device simultaneously with gastrectomy.     

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.     

Nasogastric decompression after total gastrectomy

BACKGROUND/AIMS: Although it is clearly known that there is no need of routine nasogastric decompression after some abdominal operations, we still do not know whether it is necessary for esophageal anastomosis. Traditionally, nasogastric decompression is mandatory after total gastrectomy complemented with esophagojejunostomy. METHODOLOGY: Consecutive 66 patients with gastric cancer who underwent total gastrectomy and esophagojejunostomy were prospectively evaluated. Patients were divided into two groups, those with nasogastric decompression and those without decompression. RESULTS: Postoperative complications were similar among the groups. Vomiting, distention, belching, hiccupping, dysphagia complaints were similar among the groups, but sore throat (100% vs. 22%, p<0.001), nausea (32% vs. 13%, p=0.054), fever (35% vs. 16%, p=0.068) and pulmonary complications (26% vs. 9%. p=0.072) were much more in the nasogastric decompression than the no-tube group. Starting oral feeding and postoperative hospital stay were similar in both groups. CONCLUSIONS: Omission of nasogastric decompression after elective total gastrectomy complemented with esophagojejunostomy did not increase postoperative complications, on the contrary it decreased postoperative fever and pulmonary problems, and improved patient comfort by decreasing sore throat and nausea. Therefore, we do not recommend the routine use of nasogastric tubes after total gastrectomy complemented with esophagojejunostomy.     

Complication of jejunal pouch interposition after proximal gastrectomy: case report

Interposition of a jejunal pouch after proximal gastrectomy is a popular reconstruction method in Japan, because it produces a good quality of life soon after surgery. Many reports have described its usefulness. However, there are few reports describing its complications. We report here for the first time a case of pouch stasis needing surgery. A 23-year-old man underwent proximal gastrectomy with interposed jejunal pouch for traumatic strangulated diaphragmatic hernia. Three years later, he complained of persistent vomiting. Since surgery, he had eaten as much as other young people. An upper gastrointestinal series showed dilatation of the jejunal pouch and stasis of contrast medium. Since conservative therapy was not effective, surgery was performed. In the operative findings, the jejunal pouch was extremely dilated, the remaining stomach had become atrophic, and moreover, the anastomosis was severely distorted. It was considered that frequent excessive ingestion caused irreversible dilatation of the jejunal pouch, resulting in pouch stasis. Even though the jejunal pouch is interposed for reconstruction, it is very important to give nutritional guidance to patients, especially young patients, to prevent pouch stasis caused by excessive food ingestion.     

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.     

Cost-benefit of follow-up after total gastrectomy

An appraisal in terms of cost/benefit or follow-up gastrectomy for gastric cancer is made. Between 1981 and 1987, 90 patients underwent surgery (resectability 94%); of the radically treated patients, 32 underwent total gastrectomy (55%) and 26 subtotal resection (44%). In the group of 32 patients receiving palliative treatment, 11 underwent total gastrectomy. Two patients (4.6% died postoperatively of pulmonary complications and hyperosmolar coma during TPN. Instrumental, clinical and laboratory follow-up was performed in 82 patients out of 88 (93%), 6 not being available for outpatient follow-up. Our standard follow-up examination in these patients includes the following studies (chest x-ray, EGD, liver ultrasound, upper abdominal CT scan, cholescintigraphy with HIDA and barium examination of the upper G.I., tract when needed) performed every 6 months for the first 2 years and then annually for the next 5 years. Laboratory tests were performed every 3 months for the first 2 years and then every 12 months in order to monitor both evolution of neoplasia and possible metabolic functional problems. In the group of patients who underwent total radical gastrectomy, no side-effects or dysfunctional problems were observed, and the recovery of body weight was never less than 80% of the weight prior to diagnosis of the disease. Until now, 4 deaths due to neoplasia have occurred, 2 of which following recurrences after total gastrectomy for peritoneal carcinosis and multiple liver metastases, with an average survival time of 21 months.(ABSTRACT TRUNCATED AT 250 WORDS)     

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.     

Technique for laparoscopic autonomic nerve preserving total mesorectal excision

With the introduction of total mesorectal excision (TME) for treatment of rectal cancer, the prognosis of patients with rectal cancer is improved. With this better prognosis, there is a growing awareness about the quality of life of patients after rectal carcinoma. Laparoscopic total mesorectal excision (LTME) for rectal cancer offers several advantages in comparison with open total mesorectal excision (OTME), including greater patient comfort and an earlier return to daily activities while preserving the oncologic radicality of the procedure. Moreover, laparoscopy allows good exposure of the pelvic cavity because of magnification and good illumination. The laparoscope seems to facilitate pelvic dissection including identification and preservation of critical structures such as the autonomic nervous system. The technique for laparoscopic autonomic nerve preserving total mesorectal excision is reported. A three- or four-port technique is used. Vascular ligation, sharp mesorectal dissection and identification and preservation of the autonomic pelvic nerves are described.     

Vitamin D status after total gastrectomy

Serum levels of 25-hydroxyvitamin D, 24,25-dihydroxyvitamin D, 1,25-dihydroxyvitamin D, immunoreactive parathyroid hormone, and urinary excretion of nephrogenous cyclic AMP were measured in 25 patients after total gastrectomy. Two types of reconstruction after total gastrectomy were also compared. Serum 25-hydroxyvitamin D levels were significantly decreased and serum 24,25-dihydroxyvitamin D levels were markedly reduced, whereas serum 1,25-dihydroxyvitamin D levels were significantly increased in the patients. Although serum levels of immunoreactive parathyroid hormone did not show a significant difference, serum alkaline phosphatase levels and urinary excretion of nephrogenous cyclic AMP were significantly increased in the patients. The results suggest that defective vitamin D storage and enhanced vitamin D action coexist in patients after total gastrectomy and that the enhanced vitamin D action, possibly derived from slightly increased parathyroid function, would be a compensatory mechanism to sustained calcium deficiency. No substantial difference of vitamin D status was observed between the two types of reconstruction which differed in passage through the duodenum.This study was supported in part by a research grant from the Intractable Diseases Division, Public Health Bureau, Ministry of Health and Welfare, Japan, and in part by a grant from Chugai Pharmaceutical Company, Tokyo, Japan.     

Adenocarcinoma arising in Barrett's esophagus after total gastrectomy

A 64-yr-old Japanese male who underwent a partial gastrectomy for a duodenal ulcer at the age of 21, a total resection of the remnant stomach for a stomal ulcer at age 25, and in whom Barrett's esophagus was diagnosed at age 47, was found to have a tumor at the distal esophagus and was operated on by thoracic esophagectomy. The tumor was a well to moderately differentiated adenocarcinoma invading down to the muscularis propria. The entire esophageal mucosa in the resected specimen was lined by columnar epithelium. This tumor was thought to derive from the Barrett's esophageal epithelium.
