Post-gastrectomy complications have been the associated sequelae after curative gastrectomy for long time. They include a conundrum of symptoms ranging from serious metabolic alterations to disorders attributed to mechanical and neural factors after reconstruction of the digestive continuity. Though, with the advancement in the surgical expertise and techniques and shift towards medical and endoscopic management for benign gastro-duodenal ulcer disease, there has been a decline in the incidence of these complications; they continue to raise "red flags" after major oncologic gastric resections. Identification of these symptoms and protocol based management of the same is of utmost importance in the surgical armamentarium of trainees and practicing physicians and surgeons., (Celsius.)

Background: Laparoscopic sleeve gastrectomy (LSG) can result in de novo and worsen preexisting gastroesophageal reflux disease (GERD). Post-LSG patients with GERD refractory to proton pump inhibitors (PPI) usually undergo more invasive, anatomy-altering Roux-en-Y gastric bypass surgery. Lower esophageal sphincter (LES) electrical stimulation (ES) preserves the anatomy and has been shown to improve outcomes in GERD patients., Objective: To evaluate the safety and efficacy of LES-ES in post-LSG patients with GERD not controlled with maximal PPI therapy., Setting: Prospective, international, multicenter registry., Methods: Patients with LSG-associated GERD partially responsive to PPI underwent LES-ES. GERD outcomes pre- and poststimulation were evaluated based on quality of life, esophageal acid exposure (after 6-12 mo), and PPI use., Results: Seventeen patients (11 female, 65%), treated at 6 centers between May 2014 and October, 2016 with a median follow-up of 12 months (range 6-24), received LES-ES. Median age was 48.6 years (interquartile range, 40.5-56), median body mass index 31.7 kg/m 2 (27.9-39.3). All patients were on at least daily PPI preoperatively; at last follow-up, 7 (41%) were completely off PPI, 5 (29%) took PPI on an intermittent basis, and 5 (29%) were on single-dose PPI. Median GERD-health-related quality of life scores improved from 34 (on-PPI, 25-41) at baseline to 9 (6-13) at last follow-up (off-PPI, P<.001). Percentage of time with esophageal pH<4 improved from 13.2% (3.7-30.7) to 5.8% (1.1-54.4), P = .01., Conclusion: LES-ES in post-LSG patients suffering from symptomatic, PPI-refractory GERD resulted in significant improvement of GERD-symptoms, esophageal acid exposure, and need for PPI. Preserving the post-LSG anatomy, it offers a valid option for patients unable or unwilling to undergo Roux-en-Y gastric bypass surgery., (Copyright © 2018 American Society for Bariatric Surgery.

Background: The afferent syndrome loop is a mechanic obstruction of the afferent limb before a Billroth II or Roux-Y reconstruction, secondary in most of case to distal or subtotal gastrectomy. Clinical case: Male 76 years old, with antecedent of cholecystectomy, gastric adenocarcinoma six years ago, with subtotal gastrectomy and Roux-Y reconstruction. Beginning a several abdominal pain, nausea and vomiting, abdominal distension, without peritoneal irritation sings. Amylase 1246 U/L, lipase 3381 U/L. Computed Tomography with thickness wall and dilatation of afferent loop, pancreas with diffuse enlargement diagnostic of acute pancreatitis secondary an afferent loop syndrome., Conclusion: The afferent loop syndrome is presented in 0.3%-1% in all cases with Billroth II reconstruction, with a mortality of up to 57%, the obstruction lead accumulation of bile, pancreatic and intestinal secretions, increasing the pressure and resulting in afferent limb, bile conduct and Wirsung conduct dilatation, triggering an inflammatory response that culminates in pancreatic inflammation. The severity of the presentation is related to the degree and duration of the blockage.

Obesity is rapidly becoming one of the major challenges for health care systems. Surgery has proved to be one of the most effective methods of helping patients to achieve sustainable weight loss. Laparoscopic sleeve gastrectomy is a relatively new bariatric surgical technique. A staple line is placed in a line parallel to the lesser curve of the stomach, excluding up to 85% of the volume of the stomach. The excluded stomach is then resected leaving a 'tube' of residual stomach. Radiologists may be asked to perform and interpret imaging studies in the postoperative period and should be familiar with the normal appearances and common complications. Postoperative radiological investigations will typically be for suspected leak or obstruction. A water soluble contrast upper gastrointestinal (UGI) series should be performed in both suspected leak and obstruction if the patient is conscious and able to swallow. A normal postoperative UGI series will show free flow of contrast into the gastric remnant, which will be tubular with no spillage of contrast beyond the staple line, which is located on the caudal aspect of the gastric remnant. Stenosis or obstruction of the stomach may occur if the stomach remnant is too tight or torsion of the stomach. Stenosis is usually treated endoscopically with dilation and torsion is treated surgically. Leaks are often treated with covered stents which may be placed with endoscopic or radiological guidance. Collections may be drained under fluoroscopic, ultrasound or computed tomography guidance., (© 2012 The Authors.

Obesity is a major medical problem both within Australia as well as throughout the developed world. Achievement of weight loss for any individual patient brings an additional desirable benefit of improvement or resolution of a wide range of comorbid conditions. Bariatrics is the branch of medicine that deals with the causes, prevention and treatment of obesity and allied diseases. The term bariatrics was created around 1965, from the Greek root baro ('weight' as in barometer), suffix-iatr (relating to medical treatment) and suffix -ic ('pertaining to'). Besides the pharmacotherapy of obesity, it is concerned with obesity surgery. Bariatric surgery refers to surgical procedures of the gastrointestinal tract that are designed to induce weight loss. The treatment of obesity traditionally relied on non-surgical techniques to modify behaviour in regard to diet and exercise. This has variable and limited success. More recently, bariatric surgery has become the most rapidly growing form of treatment for obesity in recent years. In fact, it is the only current therapy that has been shown to achieve major and durable weight loss. It is important for the radiologist to be familiar with the normal anatomical appearance of the more common bariatric operations and to be able to recognise their potential complications on imaging. The aim of this pictorial essay is to give an insight into some of the more common complications of laparoscopic adjustable gastric banding surgery encountered in our centre during the period of 2001-2007., (© 2012 The Authors.

Gastrectomy saves the lives of many patients with gastric cancer. However, this surgical treatment is associated with clinical problems called postgastrectomy syndrome (PGS) which affect the quality of life (QOL) of such patients. For surgeons, improving the QOL after gastrectomy is an important goal after performing curative surgery. In the clinical setting, various surgical procedures such as limited resection, function-preserving procedures, and reconstruction using gastric substitutes have been advocated to reduce the severity of PGS. However, the actual conditions and pathophysiology of PGS have not been fully investigated. Various clinical studies and basic research have partially clarified the features and pathophysiology of PGS, although the strategies developed to treat PGS have been limited. The development of standardized, reliable instruments for understanding PGS and performing large-scale collaborative studies are required to improve the diagnosis and treatment of PGS. In Japan, such a project called the PGSAS has recently been completed. The results are being analyzed and will be reported in the near future.

Unlabelled: This prospective longitudinal study on gastric carcinoma patients with gastrectomy was designed to answer the question about changes in several determinants of the quality of life (QL) at various times before and after surgery and to obtain evidence for specific approaches of therapeutic intervention., Methods and Patients: 36 patients were given a questionnaire structured according to Eypasch et al. (self- assessment) before surgery, at discharge from the hospital, and after 3 and 6 months. The dual structure of the questions makes it possible to determine whether a single item is present at all (prevalence) and to what extent it impairs the quality of life (no impairment/some/moderate/strong impairment--corresponding to 0-3). The data were evaluated per domain of QL as well as item-related., Results: Postoperatively, 14 patients had to be excluded from the study because of non-radical surgery, complications, recurrences, etc. After 6 months the items of all QL-determinants showed the lowest prevalence with the exception, however, of the somatic determinants, the items of which showed a prevalence of 27 % preoperatively, 64 % at discharge from the hospital, 58 % after 3 months, and 46 % after 6 months. The average degree of QL-impairment increased continuously from 1.17 preoperatively to 1.61 after 6 months. Preoperatively the psychic domain was predominantly impaired, postoperatively the somatic domain., Conclusion: Analysis of the subjective quality of life can reveal care deficits. Gastrectomy-associated symptoms seem to influence the quality of life considerably in the first 6 months after surgery. More attention has to be paid to the sequelae of surgery. The high pre- and postoperative frequency of psychic impairment makes it desirable to provide special psychooncological offers of care.

Background/aims: We modified the surgical procedure for segmental gastrectomy, which is normally used for peptic ulcers, to treat early gastric cancer of the mid-stomach. In this paper, we describe the surgical technique and its results., Methodology: The location of the tumor was confirmed by intra-operative endoscopic examination. An area 2 cm proximal and distal to the tumor was marked with sutures. Firstly, the lymph nodes were dissected from around the perigastric and along the left gastric and common hepatic arteries. Then, a segmental gastrectomy was performed. The greater omentum, omental sac, and vagal nerve, including the hepatic, pyloric and celiac rami, were left intact. An end-to-end gastrogastrostomy was performed using Gambee's sutures and 4-0 monofilament polydioxanone. Gastric drainage was not necessary., Results: We performed segmental gastrectomies on 30 patients. Tumors less than 1 cm in diameter were found in 4 patients; 1.1-2 cm in 14, 2.1-5 cm in 11, and a tumor exceeding 5.1 cm in one patient. The cancer was confined to the mucosa in 23 patients; in the other 7, it had penetrated the submucosa. No lymph node metastases were found but 2 patients had microscopic invasion or permeation of the lymphatic vessels. One patient required post-operative balloon dilation of the pyloric sphincter for delayed gastric emptying. The remaining patients had no post-operative complications. To date, 29 patients, excluding one who died in a traffic accident, have survived disease-free for a mean of 30 months (range: 7-51). Their body weight and dietary volume returned to pre-operative levels within 12 months of surgery., Conclusions: Patients who underwent segmental gastrectomy have had a reasonably good quality of life in the post-operative follow-up to date.

Seventeen cases of carcinoma of the stomach occurring late after previous gastric operation are presented. In all instances, patients had undergone gastroenterostomy, with or without gastric resection. Most patients had undergone the initial operation for peptic ulcer disease an average of 18 years before presenting with the tumor. Endoscopic biopsy of the gastroenterostomy and gastric cytologic evaluation offered a high degree of sensitivity and specificity in making the diagnosis. These tumors appeared to originate in the gastric mucosa near the stoma. Survival was poor with both curative and palliative therapy. Alkaline bile reflux, achlorhydria and bacterial colonization are discussed as possible causes. Patients who have undergone partial gastric resection are at increased risk for the development of carcinoma of the stomach remnant. We recommend that any patient in whom new upper gastrointestinal symptoms develop more than 10 hears after partial gastrectomy should undergo endoscopy with biopsy of the gastric mucosa adjacent to the anastomosis.
