Abstract
BACKGROUND The interplay between the nervous system and cancer plays an important role in the initiation and progression of gastric cancer. Few studies have presented evidence that the sympathetic nervous system inhibits the occurrence and development of gastric cancer while the parasympathetic nervous system promotes the growth of gastric cancer. To investigate the effect of vagotomy, which is the resection of a parasympathetic nerve innervating the stomach, on the progression of gastric cancer, a retrospective study was conducted comparing the prognosis of simple palliative gastrojejunostomy (PGJ) and palliative gastrojejunostomy with vagotomy (PGJV). METHODS From January 01, 2000, to December 31, 2021, the medical records of patients who underwent PGJ or PGJV because of gastric outlet obstruction due to incurable advanced gastric cancer at the Yeungnam University Medical Center were retrospectively reviewed. Patients were divided into two groups: locally unresectable gastric cancer (LUGC) or gastric cancer with distant metastasis (GCDM), according to the reason for gastrojejunostomy, and factors affecting overall survival (OS) were analyzed. RESULTS There was no significant difference in surgical outcomes and postoperative complications between the patients with PGJV and patients with PGJ. In univariate analysis, vagotomy was not a significant factor for OS in the GCDM group (HR 1.14, CI 0.67-1.94, p value 0.642), while vagotomy was a significant factor for OS in the LUGC group (HR 0.38, CI 0.15-0.98, p value 0.045). In multivariate analysis, when vagotomy is performed together with PGJ for LUGC, the OS can be significantly extended (HR 0.25, CI 0.09-0.068, p value 0.007). CONCLUSIONS When PGJ for LUGC was performed with vagotomy, additional survival benefits could be achieved with low complication risk. However, to confirm the effect of vagotomy on the growth of gastric cancer, further prospective studies using large sample sizes are essential.

Abstract
General surgical procedures on the gastrointestinal tract are commonly performed worldwide. Surgical resections of the stomach, small intestine, or large intestine can have a significant impact on the anatomy and physiological environment of the gastrointestinal tract. These physiological changes can affect the effectiveness of orally administered formulations and drug absorption and, therefore, should be considered in rational drug formulation design for specific pathological conditions that are commonly associated with surgical intervention. For optimal drug delivery, it is important to understand how different surgical procedures affect the short-term and long-term functionality of the gastrointestinal tract. The significance of the surgical intervention is dependent on factors such as the specific region of resection, the degree of the resection, the adaptive and absorptive capacity of the remaining tissue, and the nature of the underlying disease. This review will focus on the common pathological conditions affecting the gastric and bowel regions that may require surgical intervention and the physiological impact of the surgery on gastrointestinal drug delivery. The pharmaceutical considerations for conventional and novel oral drug delivery approaches that may be impacted by general surgical procedures of the gastrointestinal tract will also be addressed.

Abstract
BACKGROUND Older data indicate that less patients undergo surgery for complicated peptic ulcer disease (PUD). We evaluated contemporary trends in the surgical management and outcomes of patients with complicated PUD. METHODS The National Inpatient Sample (2005-2014) was queried for patients with complicated PUD (hemorrhage, perforation, or obstruction). Trend analyses were used to evaluate changes in management and outcomes. RESULTS There were 1 570 696 admissions for complicated PUD during the study period. Majority (87.0%) presented with hemorrhage, 10.6% presented with perforation, and 2.4% had an obstruction. The average age was 67 years. Overall, admissions with complicated PUD decreased from 180 054 in 2005 to 150 335 in 2014. The proportion of patients managed operatively decreased from 2.5% to 1.9% in the hemorrhage group, 75.0% to 67.4% in the perforation group, and 26.0% to 20.2% in the obstruction group (all P-trend < .05). Overall, among patients managed operatively, the use of acid-reducing procedures decreased from 25.9% to 13.9%, mortality decreased from 11.9% to 9.4% (both P-trend < .001), while complications remained stable (10.4% to 10.3%, P-trend = .830). CONCLUSIONS There are fewer admissions with complicated PUD and more patients are treated nonoperatively. Despite subtle improvements, significant proportions of patients still die from complicated PUD indicating the need for improved preoperative optimization and postoperative care among these patients.

Abstract
INTRODUCTION AND OBJECTIVES Self-expanding metallic stents (SEMS) are the ideal treatment for malignant gastric outlet obstruction (MGOO) in patients with a short life expectancy, but stent dysfunction is frequent. The primary aim of our study was to identify the predictive factors of SEMS dysfunction in MGOO and the secondary aim was to determine the technical success, clinical success, and nutritional impact after SEMS placement. MATERIAL AND METHODS A retrospective, longitudinal study was conducted at the gastrointestinal endoscopy department of the Instituto Nacional de Cancerología in Mexico City. Patients diagnosed with MGOO that underwent SEMS placement within the time frame of January 2015 to May 2018 were included. We utilized the gastric outlet obstruction scoring system (GOOSS) to determine clinical success and SEMS dysfunction. RESULTS The study included 43 patients, technical success was 97.7% (n=42), and clinical success was 88.3% (n=38). SEMS dysfunction presented in 30.2% (n=13) of the patients, occurring in<6 months after placement in 53.8% (n=7) of them. In the univariate analysis, the histologic subtype, diffuse gastric adenocarcinoma (p=0.02) and the use of uncovered SEMS (p=0.02) were the variables associated with dysfunction. Albumin levels and body mass index did not increase after SEMS placement. Medical follow-up was a mean 5.8 months (1-24 months). CONCLUSIONS SEMS demonstrated adequate technical and clinical efficacy in the treatment of MGOO. SEMS dysfunction was frequent and diffuse type gastric cancer and uncovered SEMS appeared to be dysfunction predictors.

Abstract
INTRODUCTION Segmental duodenal resections (DR) have been increasingly performed for the treatment of primary duodenal tumours. The aim of the study is to review the indications for, clinical and operative details, and outcomes of patients undergoing elective DR. MATERIAL AND METHODS We retrospectively reviewed all patients who underwent elective segmental DR for the treatment of primary duodenal tumours, at a single institution between January 2007 and December 2013. Demographic data, clinical presentation, preoperative investigations, operative details, postoperative complications/mortality and histopathological results were recorded. RESULTS In the study period, 11 duodenal resections were performed (7 male, median age 61 years). Thirty-six percent of the patients presented with anaemia. Surgical resection included two or more segments in seven patients. The most frequently resected part of the duodenum was segment 3 (n = 7). Median operative time was 191 min and blood loss was 675 ml. End-to-end and end-to-side anastomoses were performed in equal numbers. The pathology of resected specimens included adenocarcinoma (n = 4), gastrointestinal stromal tumour (GIST) (n = 1), adenoma (n = 5) and lymphoma (n = 1). Median hospital stay was 14 days. Overall, 30-day morbidity rate was 82% (78% Clavien 2 or less). CONCLUSIONS Segmental duodenal resection is a safe and effective surgical technique for the resection of primary duodenal tumours.

Abstract
BACKGROUND Gastric outlet obstruction poses diagnostic and therapeutic challenges to general surgeons practicing in resource-limited countries. There is a paucity of published data on this subject in our setting. This study was undertaken to highlight the etiological spectrum and treatment outcome of gastric outlet obstruction in our setting and to identify prognostic factors for morbidity and mortality. METHODS This was a descriptive prospective study which was conducted at Bugando Medical Centre between March 2009 and February 2013. All patients with a clinical diagnosis of gastric outlet obstruction were, after informed consent for the study, consecutively enrolled into the study. Statistical data analysis was done using SPSS computer software version 17.0. RESULTS A total of 184 patients were studied. More than two-third of patients were males. Patients with malignant gastric outlet obstruction were older than those of benign type. This difference was statistically significant (p < 0.001). Gastric cancer was the commonest malignant cause of gastric outlet obstruction where as peptic ulcer disease was the commonest benign cause. In children, the commonest cause of gastric outlet obstruction was congenital pyloric stenosis (13.0%). Non-bilious vomiting (100%) and weight loss (93.5%) were the most frequent symptoms. Eighteen (9.8%) patients were HIV positive with the median CD 4+ count of 282 cells/μl. A total of 168 (91.3%) patients underwent surgery. Of these, gastro-jejunostomy (61.9%) was the most common surgical procedure performed. The complication rate was 32.1 % mainly surgical site infections (38.2%). The median hospital stay and mortality rate were 14 days and 18.5% respectively. The presence of postoperative complication was the main predictor of hospital stay (p = 0.002), whereas the age > 60 years, co-existing medical illness, malignant cause, HIV positivity, low CD 4 count (<200 cells/μl), high ASA class and presence of surgical site infection significantly predicted mortality ( p< 0.001). The follow up of patients was generally poor as more than 60% of patients were lost to follow up. CONCLUSION Gastric outlet obstruction in our setting is more prevalent in males and the cause is mostly malignant. The majority of patients present late with poor general condition. Early recognition of the diagnosis, aggressive resuscitation and early institution of surgical management is of paramount importance if morbidity and mortality associated with gastric outlet obstruction are to be avoided.

A rapid continuous-real-time 13C-urea breath test for the detection of Helicobacter pylori in patients after partial gastrectomy. J Clin Gastroenterol 2012; 46:293-6.

Abstract
INTRODUCTION Before the development of efficient medications for peptic ulcer disease many patients were treated surgically by partial gastrectomy. The pathogenetic role of Helicobacter pylori was also not known yet. Some of these patients may therefore still harbor H. pylori in their remnant stomach as a carcinogenic agent for gastric cancer. This could be even more relevant for patients who were operated for tumors in the stomach. The efficacy of the urea breath test (UBT) is not clear in this population. AIMS To study the prevalence of H. pylori and to evaluate the sensitivity and specificity of the continuous UBT (BreathID) in postgastrectomized patients in Israel. In this system, the pH of the stomach is lowered by the addition of citric acid that may be beneficial in the smaller and more alkalic stomach. METHODS We compared retrospectively the results of our continous UBT with a rapid urease test (RUT) and the histology in all our patients who underwent gastroscopy for any clinical indication, and had a history of partial gastrectomy during the years 2002 to 2010. Only patients in whom H. pylori was tested by all the 3 methods during the same day were included in the study. We identified 76 such patients older than 18 years and performed a statistical analysis of all possibly related clinical data. The 3 methods were compared with each other. RESULTS H. pylori was positive in 14/76 (18.4%) patients when histology was considered as the gold standard method. The positive predictive value of the continuous UBT and the RUT was 0.64 and 0.35, respectively. The negative predictive value was high by both the methods, 0.92 and 0.95, respectively. Weight loss was correlated with positivity for H. pylori (P=0.032) and a longer gastric stump was marginally related to H. pylori (P=0.071). There was no difference for H. pylori positivity between patients with Billroth I or Billroth II operations. Prevalence of H. pylori was not lower in patients who had partial gastrectomy several years earlier. CONCLUSIONS The prevalence of H. pylori is considerable even several years after partial gastrectomy. The BreathID is reliable to exclude H. pylori after partial gastrectomy. The positive predictive value of the UBT is not very high but better than the RUT. We suggest that all positive patients found by the breath test should be treated. Our results support the view that alternative noninvasive methods, such as the stool antigen test should be further studied and compared with the BreathID in larger populations.

Abstract
These authors found that laparoscopic gastrojejunostomy for the management of gastric outlet obstruction can be performed with good outcomes and acceptable complication rates. Background and Objectives: Laparoscopic gastrojejunostomy (LGJ) has been proposed as the technique preferred over open gastrojejunostomy for relieving gastric outlet obstruction (GOO) due to malignant and benign disease. This study investigates the feasibility and safety of LGJ for GOO. Methods: A retrospective review was performed of patients who underwent LGJ at Mount Sinai Medical Center from 2004 to 2008. Patient's operative course and long-term outcomes were collected. Results: Twenty-eight patients were reviewed (16 had malignancy, 7 had PUD, 3 had Crohn's disease, and one had obstruction of unclear cause). Average operative time was 170 minutes, and estimated blood loss was 80cc. One case was converted to open; another had stapler misfiring. Patients regained bowel function at a median of 3 days and remained in the hospital for a median of 8 days. There were 4 major postoperative complications (14%): 1 anastomotic leak and 1 trocar-site hemorrhage requiring reoperation and 2 gastrointestinal bleeds requiring endoscopic intervention. There were 5 minor complications (18%), including a partial small bowel obstruction, 1 patient developed bacteremia, and 3 patients had delayed gastric emptying. One patient had persistent GOO requiring reoperation 3 months later. Conclusion: LGJ can be performed for GOO with improved outcome and an acceptable complication rate compared to the open GJ reported in the literature.

Abstract
OBJECTIVE The most successful method of managing the difficult duodenum, including the stump leakage, has been the tube duodenostomy technique, but it has not gained wide acceptance and is rarely used. The purpose of this study is to describe the details of the procedure for indication, technical approach, and postoperative care. METHODS During the period from 1998 to 2006, a tube duodenostomy was performed in 31 patients for possible insecure duodenal stump closure during gastric resection, postoperative duodenal stump leakage, duodenal leak after primary closure of duodenum for perforation or injury, or anostomotic leak after choledochoduodenostomy. All of the tube duodenostomies were performed through the open end of the duodenum. We also inserted a T-tube into the common bile duct in 19 of 31 patients (61.2 %) with tube duodenostomy. RESULTS A tube duodenostomy was performed in the primary operation in 15 of 31 patients. None of those 15 patients required a second operation, and there were no leaks and no deaths. Among the larger group (31 patients), there was one (3.2 %) duodenal stump leak after tube duodenostomy, and it ceased spontaneously; one patient had a subhepatic collection after removal of the duodenostomy tube, and three patients had associated incisional infections. Two patients died; one after a myocardial infarction and the other from irreversible sepsis. The mean length of hospital stay was 26.9 days. CONCLUSIONS We conclude that tube duodenostomy is a simple, effective, and safe method to prevent rupture of an insecure duodenal stump or to treat the leakage from the duodenal stump or primary repair on the duodenum.

Abstract
BACKGROUND The purpose of this study was to determine postoperative outcomes and risk factors for morbidity and mortality in patients requiring surgery for bleeding peptic ulcer disease (PUD). Vagotomy and drainage procedures are technically simpler but are usually associated with higher ulcer recurrence rates. In contrast, vagotomy and resection approaches offer lower ulcer recurrences but represent much more challenging operations and are associated with considerable morbidity and mortality. STUDY DESIGN Data collected through the Department of Veterans Affairs National Surgical Quality Improvement Program database from 1991 to 2001 were submitted for stepwise logistic regression analysis for prediction of 30-day postoperative morbidity and mortality, rebleeding, and postoperative length of stay. The study population included all patients operated on for bleeding PUD within an 11-year period. RESULTS The 30-day morbidity, mortality, and rebleeding rates were comparable between surgical groups. Age, American Society of Anesthesiologists class, presence of ascites, coma, diabetes, functional status, hemiplegia, and history of steroid use were predictors of postoperative death. Risk factors for rebleeding included dependent functional status, history of congestive heart failure, smoking, steroid use, and preoperative transfusions. Having a resective procedure, American Society of Anesthesiologists class, hemiplegia, history of COPD, and requiring ventilator-assisted respirations before surgery were positively associated with increased length of hospital stay. CONCLUSIONS No differences were observed in 30-day mortality, morbidity, or rebleeding rates between surgical groups. Having a resective procedure was a predictor of prolonged postoperative stay. Dependent status and chronic use of steroids were predictors of both rebleeding and postoperative mortality.

Abstract
OBJECTIVE The endoscopic (13)C-urea breath test ((13)C-EUBT), which combines the urea breath test (UBT) with endoscopy, provides high accuracy for the detection of Helicobacter pylori. This study was conducted to determine whether the (13)C-EUBT using low doses of urea and short sampling times could preserve accuracy in the management of H. pylori infection. METHODS Three hundred and twenty-five patients were randomized to receive the EUBT with 100, 50 or 25 mg of (13)C-urea by endoscopic spraying. The breath samples collected at 5, 10 and 20 min were analysed using an isotope selected non-dispersive infrared spectrometer. H. pylori infection was assessed by the rapid urease test and histology. In each sampling schedule and protocol, cut-off values were calculated by a receiver operating characteristic curve. We applied the EUBT with 25 mg of (13)C-urea at 5 min to the assessment of eradication in 135 patients who had received the antimicrobial treatment or to the detection of the organism in 61 patients with previous partial gastrectomy. RESULTS Based on histology and the urease test, patients who had discordant results were excluded from the analysis. Using 100 mg of urea, the sensitivity and specificity of the test were both 100% at 10 and 20 min, and the sensitivity and specificity at 5 min were best with 98.6% and 100%, respectively. With 50 mg, they were both 100% at 20 min, and the best combination of sensitivity and specificity at 5 and 10 min was 97.3-96.6% and 97.3-100%, respectively. Even with 25 mg, the sensitivity and specificity were both 100.0% at 20 min, and at the 5 min and 10 min time point, the EUBT yielded a sensitivity of 98.7% and a specificity of 100%. There was a significant positive correlation between the test values of the 5 min (13)C-EUBT with 25 mg of test urea and those of the conventional UBT. The 5 min EUBT with (13)C-urea offered high accuracy in the assessment of H. pylori eradication, with the sensitivity and specificity being 100% and 96.4%, respectively. In patients with previous gastrectomy, the EUBT provided acceptable accuracy (a sensitivity of 96.4% and a specificity of 97.0%). CONCLUSIONS Our results indicate that the (13)C-EUBT is an accurate method for detecting H. pylori infection. The EUBT using only 25 mg of (13)C-urea at the early (5 min) time point has satisfactory diagnostic efficacy in pre- and post-eradication treatment settings, providing a less expensive and more rapid way of performing the test. The EUBT may be a reliable method of assessing H. pylori status in the remnant stomach.

Abstract
BACKGROUND This study was conducted to determine (1) whether Helicobacter pylori infection decreases in conjunction with time elapsed after gastrectomy and (2) the diagnostic efficacy of (13)C urea breath test (UBT) for H pylori in patients after gastrectomy. METHODS From January 1997 to June 1998, 86 patients who had undergone gastrectomy and 180 patients with dyspepsia without gastrectomy were enrolled. A UBT for the analysis of excess (13)CO(2)/(12)CO(2) ratio (ECR) was obtained for each patient. Each patient also underwent endoscopy to obtain gastric biopsies for histology and H pylori culture. The presence of H pylori by either histology or culture served as the standard to test the efficacy of UBT. The 86 patients with a prior gastrectomy were categorized into 3 subgroups (I, less than 1 year; II, 1 to 3 years; III, greater than 3 years), according to the interval between surgery and UBT. The initial H pylori status of these 86 patients was determined by histologic evaluation of the resected stomach. RESULTS At trial initiation, the postgastrectomy group had a lower H pylori infection rate (52.3%) as compared with the dyspeptic control group (80%). The initial H pylori status among subgroups I, II, and III was similar. There was a trend for the presence of H pylori in the stomach to decrease with increasing time elapsed after surgery (I to III: 68.8%, 48.3%, 36%, respectively; p < 0.05). The maximum UBT sensitivity and specificity achieved were 82.2% and 87.8% in the gastrectomy group and 97.2% and 96.3% in the dyspeptic group, with cutoff points of 2.5 and 4.0, respectively. CONCLUSION The prevalence of H pylori diminishes with time elapsed after gastrectomy. UBT for detection of H pylori is more effective in patients without prior gastrectomy than in patients who have undergone gastrectomy and is less effective than endoscopy for patients who have had a gastrectomy.

Abstract
A retrospective analysis was conducted of 778 patients who underwent highly selective vagotomy between 1980 and 1990. Surgery was performed for duodenal ulcers without any complications in 485 (62.3%) patients; for duodenal ulcers with complications such as stenosis, bleeding, or perforation in 270 (34.7%); for combined duodenal and ventricular ulcers in 12 (1.5%), and for ventricular ulcers alone in 11 (1.4%). Pyloroplasty was additionally performed in the presence of complications only. The incidence of intraoperative complications proved to be as high as 1.4%, occurring in 11 patients, while postoperative complications developed in 247 patients (31.7%). Although the overall mortality was 0.6% (5 patients), the mortality rate of those patients who underwent surgery for uncomplicated ulcer disease was 0.2% only (2 patients). The patients comprised 554 men (71.2%) and 224 women (28.8%) with an average age of 41.4 +/- 0.7 years. The average duration of duodenal ulcer disease was 9.5 years, and 643 (83.2%) of the patients were able to be regularly followed up for between 3 and 13 years. Recurrence developed in 62 patients (9.6%): in the duodenum in 57 patients (91.9%), and in the stomach in 5 (8.1%). The rate of recurrence according to sex was 9.4% in men and 10.3% in women, being 42 and 20 patients, respectively. The average duration until recurrence appeared was 27.06 +/- 3.44 months. A reoperation proved necessary in 28 of these 62 patients (45.1%). The clinical results were evaluated by means of a modified Visick classification, according to which 81.8% of the patients belonged to groups 1 or 2, 7.9% to group 3, and 10.3% to group 4.

Abstract
A total of 902 surgical patients with peptic ulcer disease were evaluated to clarify the effects of H2-receptor antagonists and endoscopic hemostasis on surgical treatment. Following the introduction of these treatments to our institute in 1982, the number of operations performed annually decreased by 40%, or 36 cases per year. However, a remarkable increase in the frequency of surgical emergency intervention since 1982 was concurrently observed, with the ratio of emergency procedures to the total number of operated cases increasing to 72.5% in the last 5 years of the study. Moreover, intractability as an indication for surgery decreased to 34.1%, compared with an increase in the number of patients with bleeding and perforated ulcers requiring operation. There were 13 postoperative deaths recorded (1.4%). All of the deaths were in patients who had undergone emergency surgery in poor health. Of these 13 patients, 10 had bleeding ulcers. A study of bleeding ulcers for which endoscopic hemostasis had been unsuccessful revealed that shock on admission and a concomitant medical condition had been evident in all the patients who died, and in 52.2% and 30.4% of the survivors, respectively. The current study suggests that the frequency of high-risk patients requiring surgery is increasing since the introduction of H2-receptor antagonists and endoscopic hemostasis, and thus, prompt surgical treatment and intensive management for such patients is essential.
