Total gastrectomy in the treatment of adenocarcinoma of the cardia. Review of the results in 73 resected patients.

Between January 1, 1971, and December 31, 1978, 73 patients with adenocarcinoma of the cardia were treated by total gastrectomy with distal esophagectomy. The continuity of the alimentary tract was restored by esophagojejunostomy using a Roux-Y procedure in 32 patients and jejunal loop interposition in 41 patients. The early postoperative mortality rate was 18 percent. The overall 5 year survival rate was 26.7 percent, and the 5 year survival rate for stage I and II disease was 91.6 percent and 25 percent, respectively, whereas none of the stage III and IV patients survived more than 4 years. Fifty-eight percent of the patients without nodal involvement lived more than 5 years. The 5 year survival rate was only 9.3 percent in the presence of nodal metastases. Our 5 year survival rates suggest the value of elective total gastrectomy for stage I or II adenocarcinoma of the cardia. Jejunal loop interposition is a time-consuming but functionally superior procedure in comparison to other reconstructive procedures after total gastrectomy.

Prospective evaluation of nutritional status related to body mass indices and outcomes after modified D2 gastrectomy for carcinoma.

AIMS: The aim of this study was to examine the perioperative nutritional status, body mass indices (BMI) and nutritional intakes of patients undergoing a modified D2 gastrectomy (preserving pancreas and spleen) for carcinoma to determine whether a relationship exists between the above and outcomes. METHODS: Fifty consecutive patients [median age 71 years, 38 male] with gastric adenocarcinoma were studied prospectively. RESULTS: Seven patients (14%) were obese (BMI > 30 kg/m2), 16 patients (32%) were overweight (BMI > 25 kg/m2), 21 patients (42%) were of normal weight (BMI 20-25 kg/m2), and six patients (12%) were underweight (BMI < 20 kg/m2). Operative morbidity was commoner in underweight patients (33%) when compared with overweight patients (17%, P = 0.391) and patients of normal weight (14%, P = 0.289). Fatal complications, however (two patients, 4%) were confined to overweight patients (P = 0.118). Preoperative serum albumin levels were significantly higher in overweight patients (43 g/dl) compared to underweight patients (34.5 g/dl; P = 0.003), though no correlation was found between patients' serum albumin levels and postoperative morbidity (r = -0.023, P = 0.877). Overweight patients were significantly less likely to achieve their protein requirements postoperatively than underweight patients (P = 0.037). Early enteral feeding contributed to 56% of the median energy requirements and 45% of the median protein requirements on the seventh postoperative day. CONCLUSION: BMI alone is a poor indicator of outcomes after modified D2 gastrectomy for carcinoma. The role of early enteral nutrition in patients undergoing gastrectomy for cancer deserves further evaluation.

Complications of gastrectomy following CPT-11-based neoadjuvant chemotherapy for gastric cancer.

Potential benefits of neoadjuvant therapy for locally advanced gastric cancer include tumor downstaging and an increased R0 resection rate. Potential disadvantages include increased surgical complications. This study assesses postoperative morbidity and mortality by comparing patients undergoing gastrectomy with and without neoadjuvant chemotherapy. From October 1998 to July 2002, a total of 34 patients with locally advanced gastric cancer were placed on a phase II neoadjuvant chemotherapy protocol consisting of two cycles of CPT-11 (75 mg/m(2)) with cisplatin (25 mg/m(2)). Demographic, clinical, morbidity, and mortality data were compared for these patients (CHEMO) versus 85 patients undergoing gastrectomy without neoadjuvant chemotherapy (SURG). The CHEMO patients were more likely to be less than 70 years of age (P< or =0.01), have proximal tumors (P< or =0.01), and undergo proximal gastrectomy (P< or =0.025). Fifty-two percent of SURG patients had T3/T4 tumors compared to 19% of CHEMO patients, consistent with tumor downstaging. The R0 resection rate was similar (80%). Morbidity was 41% in CHEMO patients and 39% in SURG patients. There were five postoperative deaths (4.4%), two in the CHEMO group and three in the SURG group (P=NS). It was concluded that neoadjuvant chemotherapy with CPT-11 and cisplatin is not associated with increased postoperative morbidity compared to surgery alone. CPT-11-based neoadjuvant chemotherapy should be tested further in combined-modality treatment of gastric cancer.

Comparative evaluation of gastrointestinal transit and immune response between laparoscopic and open gastrectomy in a porcine model.

Several reports have shown advantages of laparoscopic gastrointestinal (GI) procedures when compared with their open counterparts. The aim of this study was to assess the differences of GI transit and immune response between laparoscopic and open gastrectomy in a porcine model. Fourteen pigs were assigned to undergo partial gastrectomy, either by laparoscopy (lap group) or by laparotomy (open group). GI transit was assessed using 24 markers and measured until half of markers were evacuated. To assess immune response, we used delayed-type hypersensitivity skin antigen testing (DTH) with vaccine antigen. DTH was evaluated at 48 hours after the primary injection for induration. After 2 weeks, all animals underwent necropsy and were evaluated for adhesion formation using a scoring scale. Operation time was significantly longer in the lap group. The GI transit in the postoperative phase was significantly prolonged compared with the preoperative measured times. Postoperatively, the GI transit in the open group was significantly prolonged compared with the lap group. Immune response measured by DTH was better preserved in the lap group than in the open group. Adhesion formation was significantly less in the lap group. We concluded that laparoscopic gastrectomy resulted in faster bowel recovery and less immune suppression.

Long-term benefit of extended lymphadenectomy with gastrectomy in distally located early gastric carcinoma.

BACKGROUND: Extended lymphadenectomy performed with gastrectomy has been reported to prolong survival of patients with early gastric cancer. However, some authors question the value of extensive lymphadenectomy in these patients, especially since much recent discussion of patient quality of life after gastrectomy has favored less invasive operations. METHODS: We retrospectively analyzed 485 patients who had undergone gastrectomy for early cancer in order to evaluate the effect of extended versus limited lymphadenectomy on postoperative survival. Various prognostic factors were examined for patients whose tumors were located in the distal third of the stomach. RESULTS: Although extended radical lymphadenectomy did not prolong postoperative survival when early gastric cancer was located in the middle or proximal third of the stomach, it did when the tumor occupied the distal third. CONCLUSIONS: Performance of extended radical lymphadenectomy was a significant prognostic factor for early gastric cancer patients when tumors were located in the distal third of the stomach.

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.

Motility in the Hunt-Lawrence pouch after total gastrectomy.

PURPOSE: The aim of this study was to evaluate motility patterns of the Hunt-Lawrence pouch and the jejunal limb of patients reconstructed with a pouch after total gastrectomy, and to compare the findings in symptomatic patients to those without symptoms after the operation. PATIENTS AND METHODS: Thirty-three patients who had undergone post-gastrectomy pouch reconstruction were studied using a water-perfused motility system. In 21, the pouch was connected by a Roux-en-Y, and, in 12, by a jejunal interposition. Twenty-eight patients were asymptomatic, including 17 connected by a Roux-en-Y and 11 by a jejunal interposition. Five patients were by a jejunal interposition. Five patients were symptomatic, including 4 connected by Roux-en-Y Y and 1 by jejunal interposition. A control group consisted of 5 healthy volunteers who had not undergone operation. RESULTS: The motility phases in the pouch and jejunal limb of asymptomatic patients were of shorter duration than those of controls, and they followed a random sequence instead of a normal progression from phase I to II to III. Motility features were similar in the pouch and the jejunal limb. Orthograde propagation of phase III-like activity was reduced and may contribute to the pouch storage function. Four of the 5 symptomatic patients showed highly abnormal motility with hypomotile or obstructive patterns. The technique of connecting the pouch--jejunal interposition of Roux-en-Y--did not affect the motility findings. CONCLUSIONS: The altered motility occurs after a Hunt-Lawrence pouch reconstruction in asymptomatic patients. Symptoms after gastrectomy are associated with further disturbed motility that can be differentiated from the motility changes in asymptomatic patients.

Influence of the method of digestive tract reconstruction on gallstone development after total gastrectomy for gastric cancer.

The aim of this study was to evaluate whether total gastrectomy performed for gastric cancer leads to an increased risk of cholelithiasis and whether the method of reconstruction of the digestive tract influences that risk. A total of 102 patients who had undergone total gastrectomy for gastric cancer between 1980 and 1990 were studied. The preoperative prevalence of cholelithiasis was 4% in men and 12% in women. Eighty-seven patients (85%) without gallstones before surgery were reexamined after gastrectomy. The postoperative prevalence of cholelithiasis in this group was 36% in men and 19% in women. Before surgery, the difference between the expected frequency of cholelithiasis (calculated on the basis of the data of a community survey) and the observed frequency was not statistically significant (p > 0.05) either in men or women. After surgery, the observed frequency of gallstones was significantly higher than the expected frequency in men (p < 0.0001) but not in women (p = 0.06). The risk of cholelithiasis was significantly higher in patients with Roux-en-Y reconstruction (n = 55) than in those with jejunal interposition (n = 32) (log-rank test, p = 0.03), and that risk was independent of age, sex, and body mass index.

[Factors associated with morbidity and mortality after gastric bypass. Alternatives for risk reduction: sleeve gastrectomy].

INTRODUCTION: The aim of this study was to analyze factors related to morbidity and mortality after gastric bypass and to evaluate lower-risk alternatives in selected patients. PATIENTS AND METHODS: A prospective cohort of 761 patients who underwent gastric bypass was included. Prognostic factors were studied using a logistic regression model with SPSS 11.0. Independent variables were age, sex, body mass index (BMI), comorbidities, and the laparoscopic approach. Dependent variables consisted of medical complications, surgical complications, and mortality. We performed a preliminary descriptive study of morbidity and weight loss at 3 months after sleeve gastrectomy. RESULTS: In the postoperative period, 2.8% of patients presented medical complications and 5.4% presented surgical complications. Mortality was 0.52%. Surgical complications were significantly associated with age > 45 years (P = .04; OR = 2.00 [1.03-3.8]) and male sex (P = .041; OR = 2.40 [1.12-5.14]). Medical complications were significantly associated with a BMI of > 50 kg/m2 (P = .012; OR = 3.32 [1.23-8.98]), and mortality was significantly associated with a BMI of > 50 kg/m2 (P = .006) and male sex (P = .006). Sleeve gastrectomy was performed in eight patients with a BMI of > 60 kg/m2, in three patients with a BMI of > 50 kg/m2, cardiopulmonary disease and android fat distribution, and in four patients with a BMI of between 35 and 40 kg/m2 and major comorbidity. Morbidity consisted of self-limited febrile syndrome in one patient. There was no mortality. Weight loss at 3 months was 39.8 +/- 5.36% of excess BMI in superobese patients (n = 4) and was 50.2 +/- 11.05% of excess BMI in morbidly obese patients (n = 4). CONCLUSIONS: Postoperative morbidity and mortality was significantly higher in male patients, in patients aged more than 45 years, and in those with a BMI of > 50 kg/m2. Sleeve gastrectomy in selected patients could be a lower-risk alternative.

Chronic outcome of proximal gastrectomy with jejunal pouch interposition in dogs.

BACKGROUND: To prevent or minimize postgastrectomy complications, proximal gastrectomy with an interposed jejunal pouch has been advocated as an organ-preserving surgical strategy to improve quality of life for the patients. However, the utility of this surgical method has only been evaluated clinically and no reports have been published concerning animal studies. Therefore, we carried out an experiment in beagle dogs to investigate the utility of proximal gastrectomy with an interposed jejunal pouch. METHODS: Female beagle dogs weighting 8.0-10.0 kg were divided into two groups that underwent proximal gastrectomy with jejunal pouch interposition (JP group) and esophagogastrostomy (EG group). The time course of the electrophysiological changes on electromyograms were compared between the JP and EG groups. RESULTS: Electrophysiologically, a significant difference was noted between the two groups on the number of action potentials per unit time, the mean amplitude, and the length of the resting period in the preprandial state. All parameters tended to be normalized sooner after surgery in the JP group. CONCLUSIONS: The clinical superiority of jejunal pouch interposition was suggested experimentally to the same extent on electromyograms.

[Treatment of super super morbid obesity by sleeve gastrectomy].

UNLABELLED: INTEREST OF WORK: The longitudinal or "sleeve" gastrectomy was recently introduced into the therapeutic arsenal of the bariatric surgeon. It is a restrictive procedure that reduces stomach capacity by 75%. We present here a preliminary experience with four patients. METHODS: Four patients with super super obesity (body mass index (BMI)>60 kg/m2) underwent longitudinal or "sleeve" gastrectomy. Their average preoperative weight was 173 kg (range: 147-190 kg) and mean BMI 65 kg/m2 (range: 61-67 kg/m2). RESULTS: The average post-operative follow-up was 6 months (range: 2-12 months). Average weight loss at 6 months was 40 kg (range: 20-60 kg) and average decrease in BMI at 6 months 16.3 kg/m2 (range: 6-23 kg/m2). We noted a postsurgical complication in only one patient (subdiaphragmatic abscess treated with drainage). PERSPECTIVES: These preliminary results suggest that the sleeve gastrectomy is associated with few perioperative complications and offers rapidly effective treatment for super super morbid obesity. Long-term results require further investigation.

Laparoscopy-assisted distal gastrectomy with systemic lymph node dissection for early gastric carcinoma: a review of 43 cases.

BACKGROUND: Recently, laparoscopy and laparoscopy-assisted surgery have been used increasingly as less-invasive alternatives to conventional open surgery. But the use of this approach in gastric carcinoma has received little attention, possibly from the low incidence of early-stage disease in the West and the relative complexity of the surgical procedure. STUDY DESIGN: A prospective feasibility study of laparoscopy-assisted distal gastrectomy was performed in patients with histologically confirmed gastric carcinoma located in the lower or middle third of the stomach. Patients whose preoperative evaluations, including endoscopic ultrasonography and computerized tomography, led to a diagnosis of T1 N0 stage disease, and who had no advanced disease discovered during laparoscopy, were eligible. Intraoperative blood loss, time of operation, mortality, and morbidity were assessed, along with the number of lymph nodes retrieved and shortterm survival. RESULTS: Between 1998 and 1999, 43 patients were enrolled. Laparoscopy-assisted distal gastrectomy was converted to an open procedure in one patient. There were no operative or in-hospital deaths, but the incidence of anastomotic leakage was 14% (6 of 43). The mean blood loss was 239 mL, the time of operation was 225 minutes, and lymph node retrieval was 20.2 nodes. These results are comparable with a series of conventional open operations. One patient died of recurrent disease, and all other patients remain disease-free to date. Port-site recurrence was not observed. CONCLUSIONS: Although laparoscopy-assisted distal gastrectomy was equivalent to open surgery in several clinical parameters, the relatively high morbidity was a drawback. Its appropriateness to gastric cancer surgery must be verified by further studies.

Near-total completion gastrectomy for severe postvagotomy gastric stasis: analysis of early and long-term results in 62 patients.

The aim of this study was to evaluate results of completion gastrectomy for severe postgastrectomy gastric stasis. A total of 51 women and 11 men underwent completion gastrectomy for gastric stasis between 1985 and 1996; follow-up was complete in 98% at 5.4 +/- 5 years. All patients had modified Visick scores preoperatively of grade III (37%) or IV (63%). Presentation included combinations of nausea, vomiting, postprandial pain, chronic abdominal pain, and chronic narcotic use. All had undergone prior vagotomy and had a median of four previous gastric operations. Hospital mortality was zero. Complications occurred in 25 patients (40%) and included the following: narcotic withdrawal syndrome (18%), ileus (10%), wound infection (5%), intestinal obstruction (2%), and anastomotic leak (5%). All or most symptoms were relieved in 43% (Visick grade I or II), but 57% of the patients remained in Visick grade III or IV. Nausea, vomiting, and postprandial pain were reduced from 93% to 50%, 79% to 30%, and 58% to 30%, respectively (P<0.05), but chronic pain, diarrhea, and dumping syndrome were not significantly affected. Univariate analysis revealed no preoperative characteristic to be predictive of good outcome. Logistic regression analysis suggested that the combination of nausea, need for total parenteral nutrition, and retained food in the stomach predicted a poor outcome (P<0.05). Completion gastrectomy is successful in 43% of patients. The combination of nausea, need for total parenteral nutrition, and retained food at endoscopy are negative prognostic factors.

Changes in bone metabolism and body composition after total gastrectomy: results of a longitudinal study.

Decreased bone mineral density and an increased risk of fracture have been reported many years after gastric resections due to peptic ulcer disease. Corresponding information after total gastrectomy is, however, contradictory and incomplete. Twenty-two gastric cancer patients who were long-term survivors after total gastrectomy (mean of eight years) were investigated. They had whole body DXA scans performed both after a mean of five and eight years after the operation. Serum levels of relevant blood tests were determined. Our patients lost 3.2 kg of their body weight (P<0.006) with a corresponding loss of lean body mass (P<0.0001). We were unable to demonstrate any difference in bone density from values seen in age- and sex-matched controls. We found a slight elevation of osteocalcine levels but only a minor increase in parathyroid hormone levels. Body weight had the greatest impact on the T score. The impact of total gastrectomy on calcium homoeostasis and bone mineral density seems to be marginal. The close relationship between bone mineral density and body weight suggest the pivotal importance of maintaining weight control.

Early phase metabolic bone disorders after gastrectomy: influence of active vitamin D treatment.

Metabolic bone disorders are recognized as one of the late complications after gastrectomy. However, the onset time and the extent of bone disorders are still unknown. We examined the influence of active vitamin D treatment on bone metabolism in the early period after gastrectomy. Sixty-three postgastrectomy patients were divided into two groups; active vitamin D treatment group [VD(+)] and no treatment group [VD(-)]. The level of serum calcium and phosphate was increased in the VD(+) group compared with the preoperative level, and parathyroid hormone (PTH-M) was decreased in the VD(+) group. Both 1,25-(OH)2D3 and bone-specific alkaline phosphatase (B-ALP) were increased in the VD(-) group. Cross-linked carboxyterminal telopeptide of type I collagen (I-CTP) was increased in the VD(+) group. There was no change in calcitonin in either group. In conclusion, metabolic bone disorders after gastrectomy have their onset in the early period, and active vitamin D treatment from the early period may be effective in preventing bone disorders.

Survival results of a multicentre phase II study to evaluate D2 gastrectomy for gastric cancer.

Curative resection is the treatment of choice for potentially curable gastric cancer. Two major Western studies in the 1990s failed to show a benefit from D2 dissection. They showed extremely high postoperative mortality after D2 dissection, and were criticised for the potential inadequacy of the pretrial training in the new technique of D2 dissection, prior to the phase III studies being initiated. The inclusion of pancreatectomy and splenectomy in D2 dissection was associated with increased morbidity and mortality. Following these results, we started a phase II trial to evaluate the safety and efficacy of pancreas-preserving D2 dissection. The results of this trial regarding the safety of pancreas preserving D2 dissection were published in 1998. In this paper, we present the survival results of this phase II trial to confirm the rationale of carrying out a phase III study comparing D1 vs D2 dissection for curable gastric cancer. Italian patients with histologically proven gastric adenocarcinoma were registered in the Italian Gastric Cancer Study Group Multicenter trial. The study was carried out based on the General Rules of the Japanese Research Society for Gastric Cancer. A strict quality control system was achieved by a supervising surgeon of the reference centre who had stayed at the National Cancer Center Hospital, Tokyo, to learn the standard D2 gastrectomy and the postoperative management. The standard procedure entailed removal of the first and second tier lymph nodes. During total gastrectomy, the pancreas was preserved according to the Maruyama technique. Complete follow-up was available to death or 5 years in 100% of patients and the median follow-up time was 4.38 years. Out of 297 consecutive patients registered, 191 patients were enrolled in the study between May 1994 and December 1996. The overall morbidity rate was 20.9%. The postoperative in-hospital mortality was 3.1%. The overall 5-year survival rate among all eligible patients was 55%. Survival was strictly related to stage, depth of wall invasion, lymph node involvement and type of gastrectomy (distal vs total). Our results suggest a survival benefit for pancreas-preserving D2 dissection in Italian patients with gastric cancer if performed in experienced centres. A phase III trial among exclusively experienced centres is urgently needed.

Reconstruction after total gastrectomy by the interposition of a double jejunal pouch using a double stapling technique.

BACKGROUND: After total gastrectomy, sustaining good nutrition is extremely important for maintaining quality of life. A technique of neogastric pouch formation based on current physiological reconstructive principles is presented. METHODS: The use of a modified interpositioned double jejunal pouch following total gastrectomy in 18 patients with cancer was reviewed. This technique results in a complete pouch and uses a double stapling technique with site-specific anastomosis between the oesophagus and pouch, in which a Hisoid angle is created. RESULTS: There were no anastomotic leaks and pouch blood flow was within normal expected limits. Mean oesophageal pH above 7.0 for one 24-h period was 7.7 per cent. Emptying half-time was 67.8 min. After 2 years mean body-weight was 98.3 per cent of expected, mean food volume was 94.0 per cent of expected and mean meal frequency was 3.0 per day. CONCLUSION: This form of gastric reconstruction is an acceptable procedure which improves the quality of life in patients undergoing total gastrectomy.

Small bowel bacterial overgrowth in patients after total gastrectomy.

The aim of this study was to elucidate the consequences of small bowel bacterial overgrowth (SBBO) after total gastrectomy. A total of 127 patients, evaluated for SBBO with a radiographically controlled H2-breath test (subgroup I, without SBBO, n = 80; subgroup II, with SBBO, n = 47) after potentially curative total gastrectomy for gastric malignancy, were uniformly evaluated. Mean time since operation was significantly shorter in subgroup II than in subgroup I [370 days, confidence interval (CI) 96-645 days, vs. 687 days, CI 397-976 days; P < 0.01]. Controlling for this difference, there were no other significant differences in symptoms and signs between the subgroups except for the medico-social functioning measured with the Edinburgh Rehabilitation Status Scale (ERSS). The mean ERSS showed significantly better medicosocial functioning in subgroup I than in subgroup II [3.7 (CI 2.2-5.2) vs. 5.1 (CI 3.0-7.0); P < 0.05]. After total gastrectomy, patients without SBBO did not differ significantly from patients with SBBO in most parameters. Medicosocial functioning was significantly poorer in the latter.
