Postoperative complications requiring relaparotomies after 700 gastretomies performed for gastric cancer

Treatment of efferent loop syndrome after pancreatoduodenectomy with a fully covered self‐expandable metal stent: A case report

Efferent loop syndrome is a very rare complication following pancreatoduodenectomy. The treatment of efferent loop syndrome varies depending on the cause of the syndrome. Conservative treatment methods, including nasogastric drainage and enteral nutrition, are adopted that are effective in most of patients; however, surgical treatment is usually required in patients with complete loop obstruction. Herein, we report a case of severe efferent loop obstruction that occurred after pancreatoduodenectomy, which was refractory to conservative treatment and successfully resolved by insertion of a fully covered self‐expandable metal stent.

Comparison of open and laparoscopic gastrectomy for gastric cancer: a low volume center experience

Objectives

In gastric cancer, laparoscopic gastrectomy is commonly performed in Asian countries. In other regions where tumor incidence is relatively low and patient characteristics are different, developments in this issue have been limited. In this study, we aimed to compare the early results for patients who underwent open or laparoscopic gastrectomy for gastric cancer in a low volume center.

Material and Methods

We retrospectively analyzed the data of patients who underwent curative gastric resection (open gastrectomy n: 30; laparoscopic gastrectomy n: 30) by the same surgical team between 2014 and 2019.

Results

The tumor was localized in 60% (36/60) of the patients in the proximal and middle 1/3 stomach. In laparoscopic gastrectomy group, the operation time was significantly longer (median, 297.5 vs 180 minutes; p <0.05). In open gastrectomy group, intraoperative blood loss (median 50 vs 150 ml; p <0.05) was significantly higher. Tumor negative surgical margin was achieved in all cases. Although the mean number of lymph nodes harvested in laparoscopic gastrectomy group was higher than the open surgery group, the difference was not statistically significant (28.2 ± 11.48 vs 25.8 ± 9.78, respectively; p= 0.394). The rate of major complications (Clavien-Dindo ≥ grade 3) was less common in the laparoscopic group (6.7% vs 16.7%; p= 0.642). Mortality was observed in four patients (2 patients open, 2 patients laparoscopic).

Conclusion

In low-volume centers with advanced laparoscopic surgery experience, laparoscopic gastrectomy for gastric cancer can be performed with the risk of morbidity-mortality similar to open gastrectomy.

Intraoperatively Testing the Anastomotic Integrity of Esophagojejunostomy Using Methylene Blue

Background:

Intraoperative testing of gastrointestinal anastomosis effectively ensures anastomotic integrity. This study investigated whether the routine use of methylene blue intraoperatively identified leaks to reduce the postoperative proportion of clinical leaks.

Methods:

This study retrospectively analyzed consecutive total gastrectomies performed from January 2007 to December 2014 in a university hospital setting by a general surgical group that exclusively used the methylene blue test. All surgeries were performed for gastric or junctional cancers (n = 198). All reconstructions (Roux-en Y esophagojejunostomy) were performed using a stapler. The methylene blue test was used in 108 cases (group 1) via a nasojejunal tube. No test was performed for the other 90 cases (group 2). Intraoperative leakage rate, postoperative clinical leakage rate, length of hospitalization, and mortality rate were the outcome measures.

Results:

The intraoperative leakage rate was 7.4% in group 1. The postoperative clinical leakage rate was 8.6%. The postoperative clinical leakage rate was 3.7% in group 1 and 14.4% in group 2 (p = 0.007). There were no postoperative clinical leaks when an intraoperative leak led to concomitant intraoperative repair. The median length of hospital stay was 6 days in group 1 and 8 days in group 2 (p < 0.001). One death occurred in each group. No test-related complications were observed.

Conclusion:

The methylene blue test for esophagojejunostomy is a safe and reliable method for the assessment of anastomosis integrity, especially in cases with difficult esophagojejunostomic construction.

Role of percutaneous transhepatic biliary drainage in patients with complications after gastrectomy

OBJECTIVE

The aim of this study was to elucidate the role of PTBD in patients with DSL and ALS post-gastrectomy for malignancy or benign ulcer perforation.

SUMMARY OF BACKGROUND DATA

Percutaneous transhepatic biliary drainage (PTBD) is an interventional radiologic procedure used to promote bile drainage. Duodenal stump leakage (DSL) and afferent loop syndrome (ALS) can be serious complications after gastrectomy.

METHODS

From January 2002 through December 2014, we retrospectively reviewed 19 patients who underwent PTBD secondary to DSL and ALS post-gastrectomy. In this study, a PTBD tube was placed in the proximal duodenum near the stump or distal duodenum in order to decompress and drain bile and pancreatic fluids.

RESULTS

Nine patients with DSL and 10 patients with ALS underwent PTBD. The mean hospital stay was 34.3 days (range, 12-71) in DSL group and 16.4 days (range, 6-48) in ALS group after PTBD. A liquid or soft diet was started within 2.6 days (range, 1-7) in the ALS group and within 3.4 days (range, 0-15) in the DSL group after PTBD. One patient with DSL had PTBD changed, and 2 patients with ALS underwent additional surgical interventions after PTBD.

CONCLUSIONS

The PTBD procedure, during which the tube was inserted into the duodenum, was well-suited for decompression of the duodenum as well as for drainage of bile and pancreatic fluids. This procedure can be an alternative treatment for cases of DSL and ALS post-gastrectomy.

Minimally invasive management of anastomotic leak after bariatric Roux-en-Y gastric bypass

The aim of this retrospective study was to examine the anastomotic erosion due to drain and success of fibrin sealant in its management. Between 2013 and 2014, 102 patients underwent LRYGB and gastrojejunal anastomotic leak occurred due to drain erosion in 2 of them. The diagnosis was established with saliva drainage and was confirmed by upper gastrointestinal series. The absence of hemodynamic instability was directed us to conservative treatment. During the endoscopy, dehiscence was assessed and fibrin sealant was applied. The leaks healed progressively in a few days, and the drains removed within 6 days. Seven and 9 days later, the patients were discharged without any problem. Anastomotic leaks after bariatric surgery can cause severe morbidity, cost, and effects quality of life. Hemodynamically stable and drained patients are candidates for conservative methods. Endoscopic injection of fibrin sealant has been successful in closing gastric leaks.

Endoscopic treatment of efferent loop syndrome with insertion of double pigtail stent

Efferent loop syndrome is a very rare postgastrectomy syndrome that can occur following Billroth-II or Roux-en-Y reconstruction. The most common loop syndrome after gastric surgery is afferent loop syndrome; however, efferent loop syndrome has been reported in rare cases. Here, we report a case of efferent loop obstruction that occurred after postoperative adhesiolysis of a small-bowel obstruction. The patient had undergone a partial gastrectomy with Billroth II anastomosis and gastric ulcer perforation 30 years prior. The efferent loop obstruction was successfully resolved by the insertion of a double pigtail stent. To the best of our knowledge, this is the first case in the literature describing the treatment of efferent loop obstruction.

Endoscopic management of anastomotic leakage after gastrectomy for gastric cancer: how efficacious is it?

BACKGROUND

Anastomotic leak is a dreadful complication with a high mortality rate. The authors aimed to evaluate the efficacy of endoscopic closure of anastomotic dehiscence after gastrectomy in patients with gastric cancer.

METHODS

The authors retrospectively reviewed 33 patients with anastomotic leakage who had underdone endoscopic treatment among 5249 patients with gastric cancer who underwent radical total or subtotal gastrectomy. Methods of endoscopic closure included clipping with or without detachable snare, fibrosealant, Histoacryl® or stent insertion. Results of endoscopic treatment were categorized as complete, partial closure and failure.

RESULTS

The size of the tissue defect was the only factor that had statistically significant differences among the cases with complete closure, partial closure and failure (p = 0.005). For tissue defects smaller than 2 cm in size, complete closure was achieved in 19 (73.1%), partial closure in 5 patients (19.2%) and 2 failed (7.6%). For those larger than 2 cm in size, one (14.3%) was completely closed, four (57.1%) were partially closed and two (28.6%) failed.

CONCLUSIONS

Endoscopic treatment for anastomotic dehiscence smaller than 2 cm in size had excellent success rate in this study.

Stent treatment for fistula after obesity surgery: results in 47 consecutive patients

BACKGROUND

Leaks occurring after weight loss operations constitute a therapeutic challenge. There is no consensus as to what comprises state-of-the-art management of leaks after bariatric surgery. We sought to determine the efficacy and possible adverse effects of endoluminal stenting for leaks after bariatric surgery.

METHODS

We report our experience with the stent treatment of consecutive bariatric patients with a leak (retrospective cohort study). Between October 2005 and July 2010, 47 patients presented an acute leak after a bariatric procedure (61 % primary procedures, 39 % revisions). Fifteen patients were initially approached laparoscopically, and 32 were treated by nonoperative techniques. After adequate drainage and resuscitation, all 47 patients were treated by the endoscopic placement of a partially covered metallic stent, and later of a plastic stent inside the metallic prosthesis to facilitate removal. Both stents were then ablated 1 week later. Primary outcome measurement concerned healing of the fistula, as evidenced by radiographic imaging. Secondary outcomes were length of hospital stay and occurrence of peri- and postprocedural complications.

RESULTS

There was no mortality. 41 patients (87.23 %) healed with stent treatment alone; 5 of the 6 persisting leaks healed with laparoscopic intervention (intention-to-treat success rate 96 %). Complication rate was 28.7 %. Length of hospital stay was mean ± standard deviation 22.4 ± 19.38 days for the patients treated by stent alone, and 23.4 ± 18.4 days for the patients requiring additional surgery (P = NS). One patient developed a stricture and required endoscopic dilation, and one is still awaiting surgical treatment.

CONCLUSIONS

Leaks after bariatric surgery can be treated safely and effectively by endoscopic stents. In cases of persisting leaks, laparoscopic intervention is successful in a majority of cases. Late strictures seldom occur.

Minimally invasive approaches for gastric cancer-Japanese experiences

Since development of laparoscopy-assisted distal gastrectomy with lymph node dissection in 1991 in Japan, laparoscopic gastrectomy (LAG) is improving and evolving. Recently, advanced LAG techniques including D2 lymph node dissection or anastomosis after total gastrectomy have been developed. Retrospective and prospective multicenter studies have been conducted for early and non-early gastric cancers to establish high-quality evidence. This review summarizes the current trends of minimally invasive approaches for gastric cancer based on current Japanese experiences.

Complications after radical gastrectomy following FOLFOX7 neoadjuvant chemotherapy for gastric cancer

BACKGROUND

This study assessed the postoperative morbidity and mortality occurring in the first 30 days after radical gastrectomy by comparing gastric cancer patients who did or did not receive the FOLFOX7 regimen of neoadjuvant chemotherapy.

METHODS

We completed a retrospective analysis of 377 patients after their radical gastrectomies were performed in our department between 2005 and 2009. Two groups of patients were studied: the SURG group received surgical treatment immediately after diagnosis; the NACT underwent surgery after 2-6 cycles of neoadjuvant chemotherapy.

RESULTS

There were 267 patients in the SURG group and 110 patients in the NACT group. The NACT group had more proximal tumours (P = 0.000), more total/proximal gastrectomies (P = 0.000) and longer operative time (P = 0.005) than the SURG group. Morbidity was 10.0% in the NACT patients and 17.2% in the SURG patients (P = 0.075). There were two cases of postoperative death, both in the SURG group (P = 1.000). No changes in complications or mortality rate were observed between the SURG and NACT groups.

CONCLUSION

The FOLFOX7 neoadjuvant chemotherapy is not associated with increased postoperative morbidity, indicating that the FOLFOX7 neoadjuvant chemotherapy is a safe choice for the treatment of local advanced gastric cancer.

Morbidity, mortality, and pathological response in patients with gastric cancer preoperatively treated with chemotherapy or chemoradiotherapy

BACKGROUND

Significant tumor downstaging has been achieved in patients with localized gastric adenocarcinoma by preoperative chemoradiotherapy (ChRT) or induction chemotherapy (Ch). However the influence of ChRT and Ch on postoperative outcomes has not yet been clarified, with very few studies examining this issue. We retrospectively analyzed the efficacy in terms of pathological response and early postoperative complications of two protocols of preoperative ChRT and Ch for locally advanced gastric cancer.

METHODS

Between 2000 and 2008, 72 patients with operable locally advanced gastric cancer (cT3-4/N+) were treated with preoperative treatment: 1-patients receiving induction Ch or 2-neoadjuvant Ch followed by concurrent ChRT. Postoperative histopathological regression and surgical complications were investigated including variables related to patients, surgical variables, preoperative treatment, and tumor.

RESULTS

There were no differences in the incidence of complications between the ChRT and Ch groups (30.9% vs. 33.3%). The most frequent complications were nonspecific surgical complications (pneumonia [12.5%] and infection from intravenous catheters [9.7%]). Risk factors for complications were high-body mass index (BMI > 25 kg/m(2) ) and extension of surgery to the pancreas and spleen. A major pathological response was observed in 33.3% of patients, being more frequent in the ChRT group (47.6% vs. 13.3%; χ(2) , P = 0.0024).

CONCLUSIONS

Preoperative treatment with Ch or ChRT for locally advanced gastric cancer can be performed safely with an acceptable operative morbidity and low operative mortality rate with careful consideration of the added risk associated with BMI and surgical resection of the pancreas and spleen. Ch and ChRT is feasible and effective in terms of pathological response and R0 resection.

Early dumping syndrome and reflux esophagitis prevention with pouch reconstruction

BACKGROUND

Total gastrectomy causes numerous disorders, such as reflux esophagitis, dumping syndrome, malabsorption, and malnutrition. To minimize the consequences, different variants of reconstruction are performed. The aim of our study is the comparison of two reconstructive methods: the standard Roux-en-Y and a new modality of pouch interposition, preduodenal-pouch interposition. This study aims to investigate the advantage of bile reflux prevention and to reduce symptoms of dumping syndrome after 3- and 6-mo follow-up.

MATERIALS AND METHODS

A total of 60 patients were divided in two groups: (A) 30 patients with Roux-en-Y reconstruction, and (B) 30 patients with the preduodenal-pouch (PDP) type of reconstruction. Endoscopic examination and endoluminal jejunal limb pressure measurements were performed. Scintigraphic measurements of half-emptying time were performed to evaluate meal elimination in the context of reflux esophagitis and early dumping syndrome. The Japan Society of Gastrointestinal Surgery has provided guidelines with which to classify the symptoms of early dumping syndrome. Patients were followed up for periods of 3 and 6 mo after the surgery.

RESULTS

Our study groups did not differ with regard to the level of reflux esophagitis (P = 0.688). Average values of pressure at 10 and 15 cm below the esophago-jejunal junction were significantly lower in the PDP group (P < 0.001). Elimination of the test meal between two groups was not significant (P = 0.222). Evaluation of early dumping syndrome symptoms revealed a significant reduction among PDP patients after 3 and 6 mo.

CONCLUSION

Our study showed significant superiority of the new pouch reconstruction over the standard Roux-en-Y approach in the treatment of early dumping syndrome.

Revisional surgery after gastrectomy for gastric cancer: review of the literature

Recent reports have shown that morbidity and mortality after gastrectomy for gastric cancer vary between authors, countries, and procedures. Common complications related to gastrectomy are postoperative bleeding, anastomotic leakage, pancreatic juice leakage, intra-abdominal abscess, intestinal obstruction, wound dehiscence, and so on. Recently, laparoscopic gastrectomy for gastric cancer has developed, especially in Japan and East Asian countries because it is less invasive. Several retrospective studies have shown that the operative complication rate is similar to that of conventional open surgery. Although most postoperative complications can be successfully treated by conservative therapies, surgical management is occasionally needed to prevent a fatal outcome. This review article provides insight into how surgeons can make efforts to reduce postoperative complications through proper preoperative evaluation and improved surgical skills during the initial gastrectomy. In addition, it reviews guidance for timely revisional surgery to allow salvage of patients with serious acute operative complications based on clinical findings made by a group of experienced surgeons.

[Analysis of postoperative morbidity in patients with gastric adenocarcinoma treated using a protocol of preoperative chemoradiotherapy and surgery]

INTRODUCTION

The impact of neoadjuvant treatment on the postoperative complications in stomach cancer is a subject of controversy. The aim of this study is to analyse the post-surgical morbidity and mortality in a group of patients who were treated using a chemoradiotherapy protocol before surgery, as well as to identify the possible risk factors that may be associated with the development of complications.

MATERIAL AND METHODS

Patients diagnosed with locally advanced gastric adenocarcinoma between June 2005 and June 2008 were operated on in our Centre after having followed a preoperative chemoradiotherapy protocol. Data on postoperative morbidity and mortality were collected retrospectively and the dependent variables associated with the patients, the type of intervention and the tumour characteristics were analysed.

RESULTS

A total of 40 patients were evaluated. The overall morbidity and mortality was 32.5% (13 patients) and 2.5% (1 patient), respectively. The most frequent complications were pneumonia in 12.9% and sepsis due to the catheter in 9.7% of the patients. The risk factors for the development of complications were the body mass index (BMI 25 kg/m(2)) and the inclusion of the pancreas and/or spleen in the resection.

CONCLUSIONS

Preoperative treatment with chemoradiotherapy in patients with locally advanced stomach cancer does not increase the incidence of post-surgical complication. The preoperative condition of the patient (BMI) and extending the surgery to the spleen and pancreas are prognostic factors of early postoperative complications.

Complications requiring reoperation after gastrectomy for gastric cancer: 17 years experience in a single institute

INTRODUCTION

Morbidity and mortality rates following gastric cancer surgery are still high. The present study documented complications requiring reoperation after gastrectomy for gastric cancer and described surgical management for each complication.

MATERIALS AND METHODS

Between 1987 and 2004, 8,033 patients underwent gastrectomy at the Department of Surgery, College of Medicine, Yonsei University, and the records were reviewed.

RESULTS AND DISCUSSION

The most frequent complication was intestinal obstruction (88 patients, 54.3%), followed by intraabdominal bleeding (15, 9.3%), wound dehiscence or evisceration (15, 9.3%), incisional hernia (15, 9.3%), anastomotic leakage (seven, 4.2%), acalculous cholecystitis (five, 3.1%), duodenal stump leakage (five, 3.1%), intraabdominal abscess without leakage (five, 3.1%), bowel perforation (five, 3.1%), bile peritonitis due to hepatic duct injury (one, 0.6%), and biliary stricture (one, 0.6%). There were ten cases of hospital mortality (6.2%) from intraabdominal bleeding (four patients), intestinal obstruction (four patients), and anastomotic leakage (two patients). The most common long-term complication requiring reoperation was intestinal obstruction (69, 75.8%) due to adhesive formation rather than technical failure, while short-term complications were surgery-related and associated with high hospital mortality (14.1%).

CONCLUSION

Proper preoperative preparation and faultless surgical skills are required during initial surgery to reduce complications and the need for reoperation.

Fluoroscopically guided feeding tube insertion for relief of postoperative gastrointestinal anastomotic obstruction and leakage

PURPOSE

To evaluate the feasibility and effectiveness of feeding tube insertion and enteral feeding for the treatment of postoperative gastrointestinal anastomotic obstruction and leakage.

MATERIALS AND METHODS

From June 1999 to June 2002, thirty-four cases of postoperative gastrointestinal anastomotic obstruction and leakage after surgery for gastric carcinoma were treated by insertion of a feeding tube under fluoroscopic guidance. Twenty-one patients were male and 13 were female. The patients' ages ranged from 39 to 74 years (mean age: 61 years). All the patients experienced vomiting, and 15 patients had anastomotic site or duodenal stump leakage. We evaluated the feasibility of feeding tube insertion for enteral feeding to improve the obstruction and facilitate leakage site closure, and the patients' nutritional benefit was also evaluated by checking the serum albumin level between pre- and post-enteral feeding via the feeding tube.

RESULTS

Thirty-two patients (94%) were successfully managed by feeding tube insertion, but the remaining two were not managed, and this was due to severe angulations at the anastomotic site. The procedure times for feeding tube insertion ranged from 15 to 60 minutes (mean time: 45 minutes). Twenty-eight patients experienced symptomatic relief of gastrointestinal obstruction, and they were able to resume a normal regular diet after feeding tube removal. Three patients underwent stent insertion due to recurrent symptoms, and one patient underwent jejunostomy feeding due to the presence of a persistent leakage site. Eleven patients achieved leakage site closure after enteral feeding via a feeding tube. The serum albumin level was significant, increased from pre-enteral feeding (2.65 +/- 0.37 g/dL) to the post-enteral feeding (3.64 +/- 0.58 g/dL) via the feeding tube (p < 0.001). The duration of follow-up ranged from one to 53 months (mean: 23 months).

CONCLUSION

The insertion of a feeding tube for enteral feeding under fluoroscopic guidance is safe, and it provides effective relief from gastrointestinal anastomotic site obstruction and leakage after gastric surgery. Moreover, our findings indicate that feeding tube insertion for enteral feeding may be used as the primary procedure to treat postoperative anastomotic obstruction and leakage.

Risk factors related to operative morbidity in patients undergoing gastrectomy for gastric cancer

INTRODUCTION

The purpose of this study is to analyze postoperative morbidity and mortality of patients operated on for gastric cancer in a single institution during the last twenty years, and to define risk factors for complications.

MATERIAL AND METHODS

A retrospective study was carried out on 434 patients who underwent gastrectomy for gastric cancer between January 1983 and December 2002. Analysis of main medical and surgical complications and analysis of morbidity risk factors.

RESULTS

Overall morbidity and mortality rates were 38.4% and 2.7% respectively. The most frequent complications were pneumonia (13%) and intra-abdominal abcesses (12%). The main cause of death was anastomotic dehiscence with abdominal sepsis. The last ten years mortality rate dropped from 4.7% to 0.8%. Risk factors for complications were gender (male, p = 0.01) and resection of spleen (p = 0.02) or pancreas (p = 0.002). A significantly lesser rate of complications was found in patients who had underwent gastrectomy during the previous five years (p = 0.001) or with tumors located in the lower third of the stomach (p = 0,01).

CONCLUSION

Morbidity of gastrectomy for gastric cancer in our institution is still high but mortality has decreased significantly over the last ten years due to the specialization of the hospital and the surgical team. The main risk factor for complications was pancreatosplenectomy in the multivariate analysis.

Gastrectomia em pacientes idosos: análise dos fatores relacionados a complicações e mortalidade

OBJETIVO: Verificar as variáveis que influenciam os resultados pós-operatórios no tratamento do adenocarcinoma gástrico em pacientes idosos. MÉTODO: Foi realizada uma coorte histórica onde as principais variáveis em estudo foram: idade, localização do tumor, estadiamento, doenças associadas, complicações do procedimento cirúrgico e mortalidade operatória. Os pacientes foram separados em dois grupos em relação à idade [Grupo I (< 65 anos) e Grupo II ( 65 anos)], de maneira que os fatores associados com maior mortalidade fossem analisados de forma independente. RESULTADOS: Foram avaliados 160 pacientes submetidos à ressecção gástrica. A média de idade foi 60,7 anos. Presença de doenças associadas, classificação ASA III ou IV e mortalidade operatória foram associados com indivíduos mais velhos. Não houve diferença entre os grupos em relação à localização do tumor no estômago, ressecção empregada, estágio dos tumores e complicações pós-operatórias. A mortalidade operatória foi 6,1% no Grupo I e 12,9% no Grupo II. O principal fator de risco para o óbito na análise univariada foi a presença de doenças associadas (p<0,03). Na análise multivariada, o único fator de risco significativo para maior mortalidade foi classificação ASA mais avançada. CONCLUSÃO: Os idosos operados por adenocarcinoma gástrico apresentam fator de risco mais acentuado de morte pós-operatória. Contudo, a idade cronológica não pode ser definida como um fator determinante, e sim circunstâncias de doenças associadas e condições fisiológicas que os acompanham nessa faixa etária.

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.

The failed gastrointestinal anastomosis: an inevitable catastrophe?

BACKGROUND

There is a great deal of conflicting data regarding risk factors for anastomotic leakage, with most studies being small and looking only at anastomoses performed at one level of the gastrointestinal (GI) tract. Surgeons have looked at patient and technical variables with inconsistent findings. The purpose of this study was to evaluate the incidence, possible predictive factors, and results of treatment of anastomotic dehiscence in patients undergoing operations at all levels of the GI tract.

STUDY DESIGN

We evaluated the records of 2,842 patients undergoing esophagogastrectomy, total or partial gastrectomy, enterectomy, and partial or subtotal colectomy over a 12-year period. Complete demographic data, comorbidity, and details regarding anastomotic technique were collected on all patients sustaining leaks along with diagnostic methods used, treatment modalities, and outcomes data. Using age and gender-matched case control methodology, we compared patients sustaining an anastomotic leak to those undergoing successful anastomoses.

RESULTS

Fifty-one of 2,842 patients (1.8%), ranging from 1.1% of enterectomy patients to 4.8% of total gastrectomy patients, sustained an anastomotic dehiscence. Foregut procedures were accompanied by a significantly increased rate of leakage, and depending on location, diagnosis was made between the 6th and 9th postoperative day. For each procedure, deaths from factors other than leakage far exceeded deaths from leaks. Standard risk stratifiers did not predict occurrence of leakage. Overall, 24% of patients sustaining a leak died, and this complication necessitated multiple reoperations and significantly increased length of hospital stay.

CONCLUSIONS

In view of these findings, standard preoperative strategies to prepare these patients for operation may prove unsuccessful, because minimizing the incidence of anastomotic leaks will have little overall impact on survival. In addition, efforts to accomplish early hospital discharge may prove hazardous, because many of these patients manifest their leaks later in the postoperative period than is generally assumed. Improved management of GI tract disruption, including aggressive attempts at diagnosis, ICU care, antibiotics, and nutritional support may further increase survival in these patients.

Gastric cancer

OBJECTIVES

To review the current status, recent advances, and ongoing research related to screening, diagnosis, staging, and treatment of gastric cancer.

DATA SOURCES

Professional journals, research studies, and review articles relating to gastric cancer.

CONCLUSIONS

Surgical resection is the gold standard curative treatment for gastric cancer; however, diagnosis is often at later stages of disease, leaving poor long-term survival rates. An emphasis has been placed on developing more effective chemotherapy regimens; currently, fluorouracil is the standard single agent used for gastric cancer. Radiation therapy has been used for palliative symptom management.

IMPLICATIONS FOR NURSING PRACTICE

An understanding of current treatment modalities for gastric cancer will help oncology nurses assist their patients throughout their course of treatment with education, nutritional support, and symptom control.

Extended surgical resection in T4 gastric cancer

BACKGROUND

Some physicians still consider invasion of adjacent organs by the carcinoma of stomach as a sign of incurable disease.

METHODS

This retrospective study has been done with particular reference to 353 T4 gastric cancer patients who underwent combined gastrectomies with adjacent organs.

RESULTS

Subtotal gastrectomy was performed in 237 (67.1%) patients and total gastrectomy was performed in 116 (32.9%) patients. Organs most commonly resected with the stomach were the transverse colon in 159 (45%) cases, the tail of pancreas and spleen in 150 (42.5%), the left lobe of liver in 101 (28.5%), and the head of pancreas in 37 (10.5%) patients. A total of 110 postoperative complications occurred in this subset of patients corresponding to a complication rate of 31.2%. A total of 48 postoperative deaths occurred in this subset of patients corresponding to a mortality rate of 13.6%. The 5-year survival rate for all patients who underwent combined gastrectomy with adjacent organs was 25%. Of the node-negative T4 gastric cancer resections, 37% survived 5 years whereas the T4 node-positive resections have only a 15% 5-year survival.

CONCLUSIONS

Patients who present with T4 gastric cancer (about 20% of the patient population) will benefit from aggressive en bloc surgical resection and should not be considered unresectable.
