Duodenal closure and esophagojejunostomy experience with mechanical stapling devices in total gastrectomy for cancer.

Two hundred fifty patients with cancer underwent gastrectomy over a ten-year period. In 225 the duodenum was closed by stapler and only one disruption occurred (0.45%). The first 89 esophagojejunostomies were hand sewn, and thereafter 161 were stapled with an end-to-end anastomosis device. Overall mortality was 27% and 10%, respectively. Death due to surgical causes occurred in 19% of the cases in the first group and 6.8% in the second. No statistical difference was observed in the esophageal anastomosis leakage rate, but the mortality due to such fistula was significantly higher in the group of hand-sewn anastomoses. Surprisingly, esophageal end invasion (at the anastomotic site) was 14% in the manual group vs 3.9% in the stapled one. The operator's experience had no effect on the incidence of esophageal fistula when the stapler was used. Thus, staplers are safe and useful when total gastrectomy is undertaken, provided that sound experience has been acquired.

Splenectomy does not correlate with length of survival in patients undergoing curative total gastrectomy for gastric carcinoma. Univariate and multivariate analyses.

The relationship between splenectomy and survival time after curative total gastrectomy for advanced gastric cancer was examined by reviewing retrospectively data on 252 patients treated in our clinics between 1965 and 1985. One hundred three patients (40.9%) did not undergo splenectomy and 149 (59.1%) did. In patients subjected to splenectomy, advanced stages of the malignancy were more frequent and metastasis was noticed in 8.1% of splenic hilar lymph nodes and in 10.1% of the lymph nodes associated with the splenic artery. A univariate analysis revealed that the survival time of patients with splenectomy was significantly less than those for whom splenectomy was not done (P less than 0.05). In a subgroup of our patients stratified to adjust for the stage of disease, there was no significant difference between the survival rates. Subsequently, multivariate analysis using the Cox regression analysis adjusted for sex, age, and other covariates indicated that serosa invasion, lymph node metastasis, and tumor size were the most important prognostic factors, and there was no correlation whatever with splenectomy. Our findings rule out any relationship between splenectomy and length of survival time in patients undergoing curative total gastrectomy for advanced gastric cancer.

Relative risk of stump cancer following partial gastrectomy.

The relative risk of stump cancer following partial gastrectomy for a benign gastroduodenal condition was estimated using an individually matched retrospective study design based on autopsy material. Data on all patients dying with gastric cancer and autopsied at the Central Laboratory of Pathology, University Central Hospital, Helsinki, during 1961-75 were collected. Matched pairs of the same sex and age were used as controls. Of the 464 patients dying with gastric cancer, 9 had undergone previous partial gastrectomy, while the respective number among the controls was 5. This result suggests that the risk of cancer in the gastric stump was not significantly increased as compared to the normal unoperated population.

Anastomotic recurrence in the oesophagus complicating gastrectomy for adenocarcinoma of the stomach.

Gastric adenocarcinomas often spread to the distal oesophagus. Failure to control the disease in this area during total and proximal subtotal gastrectomy results in recurrence at the oesophageal anastomosis. The incidence of recurrence in a series of 351 such patients was 10 per cent and was influenced by the location of the main lesion, the stage of the disease, the presence of tumour at the margin of resection and the length of clearance of the oesophageal margin. Recurrence were prevented only with in vivo margins greater than 12 cm. Dysphagia combined with radiological signs of oesophageal obstruction was diagnostic of anastomotic recurrence regardless of the results obtained by oesophagoscopy and biopsy. Treatment was seldom effective in patients developing recurrence. Complete excision of the entire recurrent process offered the only hope for a long survival in these patients. Prevention by obtaining adequate oesophageal clearance at the time of gastrectomy is the only reasonable approach to this problem. The adequacy of resection cannot be judged accurately by intraoperative palpation of the oesophagus or by frozen section examination of the surgical margins.

Polya gastrectomy for recurrent ulceration following vagotomy.

Thirty-seven patients with recurrent ulceration after vagotomy were treated by Polya gastrectomy and have been followed up for a minimum of 3 years (median 5 years). The diagnosis of recurrent ulcer was made by endoscopy or at operation. Nine patients were initially treated with cimetidine and either failed to respond or relapsed on maintenance dosage. There were 2 operative deaths and 2 patients were lost to follow-up. The results of Polya gastrectomy were Visick grade I: 61 per cent, Visick grade II: 15 per cent, Visick grade III: 9 per cent and Visick grade IV: 15 per cent, Two patients had further recurrent ulceration.

Late follow-up of highly selective vagotomy with excision of the ulcer compared with Billroth I gastrectomy for treatment of benign gastric ulcer.

We present the late results of a prospective randomized trial of highly selective vagotomy with excision of the ulcer (HSV + E) (n = 26 cases) versus standard Billroth I partial gastrectomy (BI) (n = 30). The operations were performed by registrars, senior registrars or consultants. Results of postoperative morbidity, functional outcome and recurrence rates have previously been reported at an average follow-up period of 4 years (1), at which stage neither operation offered a distinct advantage. At an average follow-up period of 8 years, 54 of the original 56 patients have been reassessed, using a standard Visick grading. HSV + E offers a better symptomatic result. There is an increased recurrence rate in both groups with time, 6 following HSV + E and 5 following BI gastrectomy.

Bile acid and lysolecithin concentrations in the stomach of patients with gastric ulcer: before operation and after treatment by highly selective vagotomy, Billroth I partial gastrectomy and truncal vagotomy and pyloroplasty.

Bile acid and lysolecithin concentrations in the stomach were measured in normal subjects and in patients with gastric ulcer (GU) before operation and more than 1 year after highly selective vagotomy, Billroth I partial gastrectomy (PG) and truncal vagotomy and pyloroplasty. Before operation, patients with GU had significantly (P less than 0.001) higher bile acid concentrations in the stomach than normal people. After highly selective vagotomy, bile acid concentrations were significantly lower than in preoperative GU patients and were also significantly lower than in patients after PG, but were still higher than in normal people. Postprandial and peak lysolecithin concentrations after highly selective vagotomy were significantly lower than after partial gastrectomy. The therapeutic effect of highly selective vagotomy in the surgical treatment of GU may be due not only to reduced acid-peptic 'attack' on the gastric mucosa, but also to reduced duodenogastric reflux of 'bile'.

Endoscopic screening for premalignant changes 25 years after gastrectomy: results of a five-year prospective study.

Sixty-three partial gastrectomy patients an average 20 years after surgery were reviewed by endoscopy and biopsy in 1977. No cases of invasive carcinoma were found. The patients were then divided into two groups. Those with moderate epithelial dysplasia (13 patients) were reviewed at 6-12 monthly intervals. One patient developed severe dysplasia but none developed an invasive carcinoma. The remaining patients with either no or mild dysplasia were offered endoscopy after 5 years and 24 agreed. Of the 12 patients with no dysplasia at the outset: 5 still had no dysplasia 5 years later, 3 had mild dysplasia and 4 now had moderate dysplasia. There were 12 with mild dysplasia at the first endoscopy, 9 remained unchanged at the review and 3 had moderate dysplasia. If dysplastic changes in gastric mucosa are pre-malignant, progression to invasive carcinoma would appear to be slow. Even 25 years after gastrectomy only a modest deterioration in the grade of dysplasia was found and no invasive cancer.

Partial gastrectomy with Roux-en-Y reconstruction in the treatment of persistent or recurrent oesophagitis after Nissen fundoplication.

The results of partial gastrectomy with Roux-en-Y reconstruction in the treatment of persistent or recurrent oesophagitis after failed Nissen fundoplication in six patients were analysed. There were no postoperative deaths. Postoperative complications (pneumonia and atelectases, postoperative ileus) developed in three patients. The results were evaluated by clinical and endoscopic examination 1 to 3.5 years after the operation. Clear clinical and endoscopic improvement was observed in five of the six patients. In the remaining patient the procedure failed to prevent progression of the oesophagitis with development of a Barrett's oesophagus. The results suggest that a partial gastrectomy with Roux-en-Y reconstruction is an effective and safe procedure in the treatment of persistent or recurrent oesophagitis after failed Nissen fundoplication.

Subtotal versus total gastrectomy for cancer of the lower two-thirds of the stomach: a new approach to an old problem.

Many surgeons favour total gastrectomy (TG) 'de principe' in the treatment of gastric cancer, but final demonstration of its advantage over subtotal gastrectomy (SG) is still lacking. We analysed survival after curative TG or SG within groups of patients stratified according to the main prognostic variables as found in multivariate analysis, i.e., nodal status, degree of invasion of the gastric wall, patient age and sex. Our series consisted of 361 patients treated by curative SG and 41 by curative TG, admitted to the Istituto Nazionale Tumori of Milan between 1965 and 1979. In patients with lymph node involvement survival appeared to be significantly better (P = 0.0005) after SG. However, stratifying for age it was found that the benefit was limited to patients over 60 years old. No significant difference in survival was found in the group without nodal involvement (N -) and invasion of the wall to the serosa or beyond. No statistical comparison was possible in N - groups with invasion confined to mucosa, submucosa or muscularis propria because of the small number of such patients who underwent TG. We conclude that SG still represents the standard reference operation for gastric carcinoma provided that a safe proximal margin of resection is guaranteed.

Blind total gastrectomy for massive bleeding from the stomach.

The source of massive haemorrhage from the stomach cannot always be identified even with the use of fibreoptic endoscopy and angiography. Six patients with massive, continuing, non-variceal haemorrhage from the stomach are described in whom total gastrectomy was eventually required. Three patients were shown to have bled from submucosal arteriovenous malformations, two from erosive gastritis and one from a vessel in an ulcer at the oesophagogastric junction. One patient died as a result of surgery and another died later of disseminated malignant disease. The functional results in the remaining patients were surprisingly good and rebleeding has not occurred. Total gastrectomy is a satisfactory 'last resort' treatment for life-threatening gastric haemorrhage for which no cause can be found.

Gastric cancer: an audit of 122 consecutive cases and the results of R1 gastrectomy.

In a consecutive series of 122 patients with gastric carcinoma, 9 per cent had no operation, 27 per cent had incurable disease at laparotomy, and 64 per cent underwent gastric resection. R1 gastrectomy was performed in 73 of the 78 resections. The operative mortality after gastric resection was 4 per cent, but there were no deaths after potentially curative resections. The actuarial 5-year survival was 20 per cent overall, 60 per cent in patients undergoing a 'curative' resection with N0 disease, and 18 per cent in patients with N1 disease. Local or regional recurrence without evidence of distant metastases was identified in 11 per cent of cases after 'curative' resections. The probability of survival was adversely affected by N1 nodal involvement (P less than 0.005) and by the presence of poorly differentiated or anaplastic tumours (P less than 0.001). Only 6 per cent of patients had early gastric cancer, and absolute curative resections by Japanese criteria were possible in only 5 per cent of cases. The results suggest that the unfavourable presenting pathology is the principal determinant of the poor prognosis of gastric cancer. A more radical or extended lymphadenectomy (R2/3 gastrectomy) might have cured more patients with N1 metastases, but only 12 per cent of potentially curable patients had N1 disease in this study, and it appears that more radical surgery may have little effect on the overall survival rates for gastric cancer.

Adenocarcinoma of the cardia: treatment by thoracoabdominal R3 radical gastrectomy.

The complications and mortality rate of R3 radical gastrectomy using a left thoracoabdominal approach were studied in 38 patients with adenocarcinoma of the gastric cardia. There were two hospital deaths and two anastomotic leaks. There was a high rate of complications following surgery (subphrenic abscess, eight; severe chest infection, five; aspiration pneumonia, two; wound infection, two; and reactivation of tuberculosis, one). The hospital stay ranged from 11 to 39 days (median 21 days). Thirty-five patients had microscopic evidence of serosal involvement (S2). Thirty-three of the patients had lymph node metastases and 17 patients had involvement of N2 nodes. Four patients had histological evidence of residual suture line tumour, but only two of these returned with recurrence at the anastomosis. Follow-up (median 3 years) revealed that splenic artery nodal involvement (N2) did not worsen the prognosis after radical resection. Despite a high complication rate, thoracoabdominal radical gastrectomy is associated with an acceptable perioperative mortality rate, adequate symptom palliation and encouraging medium-term survival. The left thoracoabdominal approach gives excellent exposure for radical resection of cancer of the gastric cardia and should be the procedure of choice for curative resection of this tumour.

Risk of cancer following partial gastrectomy for benign ulcer disease.

The relative risk of developing cancer after partial gastrectomy for benign ulcer disease, expressed as the standardized incidence ratio, was examined in a population-based cohort comprising 6459 patients operated on between 1950 and 1958. Follow-up to 1983 revealed 1112 patients with cancer versus 1128 expected cases (relative risk 1.0 (95 per cent confidence interval (c.i.) 0.9-1.1)). The overall risk increased over time; it was higher in younger than in older patients but was not related to sex, surgical procedure (Billroth I or II gastrectomy) or diagnosis at operation (duodenal or stomach ulcer). There was an increased risk for lung cancer (relative risk 1.5 (95 per cent c.i. 1.2-1.7)), for oesophageal cancer in patients operated on for stomach ulcer (relative risk 2.2 (95 per cent c.i. 1.0-4.2)) and for cancer of the biliary tract in men (relative risk 1.9 (95 per cent c.i. 1.2-2.9)) and in those operated on for duodenal ulcer (relative risk 1.7 (95 per cent c.i. 1.0-2.8)). The overall risk for genital cancer in women was unchanged but decreased with increasing duration of follow-up and age. Cancers of the nervous system occurred less frequently than expected (relative risk 0.5 (95 per cent c.i. 0.3-0.8)), while the risk for cancer of the buccal cavity, lymphatic and haematopoietic systems, pancreas, breast, prostate, kidney and bladder was unchanged.

Activated carbon-oriented gastrectomy for early gastric cancer.

Twenty-two patients with early gastric cancer received injections of activated carbon particles (CH-40) to identify during surgery the location of non-palpable tumours present in the upper portion of the stomach. A few days before surgery, 0.2 ml of CH-40 was injected endoscopically into the gastric muscle adjacent to the cancer. In 20 of the 22 patients, the CH-40-stained area was recognized as a blackened patch on the serosal surface of the stomach which indicated the location of the non-palpable cancer tissue. The surgical margin for gastrectomy was defined as the proximal margin of the carbon-stained area and gastrectomies were performed on the 22 patients. CH-40 injection made it possible to choose the extent of lymph node dissection.

D2 gastrectomy: lessons from a prospective audit of the learning curve.

A 3-year prospective study of the learning curve for D2 gastrectomy was carried out by one surgeon beginning to perform the operation independently after intensive specialist training. Some 38 patients were treated; there were four postoperative deaths and 22 patients had complications. Postoperative morbidity decreased significantly with time (rS = -0.38, P = 0.02, 95 per cent confidence interval -0.62 to -0.07). The physiological component of POSSUM (Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity) was significantly lower in the third year (median value 15, 16 and 14 for years 1, 2 and 3, n = 31, chi 2 = 7.5, 2 d.f., P = 0.02, Kruskal-Wallis test), but the operative POSSUM scores and the number of lymph nodes found were not decreased (median operative POSSUM score 19, 18 and 21, n = 31, chi 2 = 0.2, 2 d.f., P = 0.91, Kruskal-Wallis test). The results suggest a learning curve lasting about 18-24 months or 15 to 25 procedures before a plateau is reached. Improved results were associated with changes in case selection and operative tactics but not with reduced extent of lymphadenectomy. D2 gastrectomy should be restricted to specialist centres where adequate training and supervision can be provided during the learning curve.

Gastrectomy with extended lymphadenectomy for primary treatment of gastric cancer.

BACKGROUND: The appropriate extent of lymph node clearance during gastrectomy for cancer remains controversial. METHODS: Medline, Embase, the Cochrane register and other databases were searched for studies reporting node dissection technique, 5 year survival and mortality after gastrectomy. Comparisons with systematic bias in treatment allocation and patients who received perioperative chemotherapy were excluded. Meta-analysis was performed separately for randomized and non-randomized comparisons. RESULTS: Two randomized and two non-randomized comparisons of limited (D1) versus extended (D2) node dissection and 11 reports of one dissection type were analysed. For D2 the randomised trials showed no overall survival benefit (Risk ratio (RR) = 0.95, 95 per cent c.i. 0.83-1.09) and an increased postoperative mortality (RR = 2.23, c.i. 1.45-3.45), apparently related to pancreatico-splenectomy and surgical inexperience. A trend towards survival benefit for D2 was observed for T3+ tumours (RR = 0.68, c.i. 0.42-1.10). Non-randomized comparisons found no survival benefit for D2 (RR = 0.92, c.i. 0.83-1.02), but decreased postoperative mortality (RR = 0.65, c.i. 0.45-0.93). Nine observational studies of D2 reported better results than two studies of D1 surgery, but in very different settings. CONCLUSIONS: Evidence for D2 dissection is inconclusive. No overall survival advantage has emerged, but some patients with intermediate stage disease may benefit. Excess operative mortality appears to be associated with pancreatico-splenectomy, low case volume and lack of specialist training.

Outcome of gastric cancer patients after successful gastrectomy: influence of the type of recurrence and histology on survival.

BACKGROUND: The effect of the location of disease recurrence after curative (R0) gastrectomy on patient survival has not been elucidated. The authors hypothesized that the location of recurrence would have a significant influence on survival. METHODS: Medical records of all patients who received treatment for gastric cancer at The University of Texas M. D. Anderson Cancer Center between 1985 and 1998 were reviewed. Patients who underwent R0 resection for gastric cancer and subsequently developed localized (anastomotic) recurrence (LR), lymph node (regional) recurrence (NR), or distant metastases (DM) were analyzed for overall survival (OS). All study factors were entered into a Cox proportional hazards model to provide multivariate hazard ratios. The model was adjusted for the effects of primary site of recurrence, histologic grade, patient age, and location of the primary tumor. RESULTS: This retrospective analysis included 227 consecutive patients. The median survival of patients who developed NR (11 months) was similar to that of patients who developed LR (10 months), but both groups had significantly longer median survival compared with patients who developed DM (7 months; log-rank P = .03). Patients who had well differentiated or moderately differentiated tumors had a longer OS (11 months) than patients who had poorly differentiated tumors (8 months; log-rank P = .02). In this cohort, location of the primary cancer and age at recurrence had no significant impact on OS. CONCLUSIONS: The data from this study suggested that, among patients who undergo R0 gastrectomy for gastric cancer, LR and NR versus DM should be considered a valid stratification factor for randomized trials based on significant differences in survival. Determining whether this stratification should apply to histologic differentiation will require further investigation in a larger multicenter cohort.
