Abstract
Chylous ascites is a rare but significant complication of a variety of surgical procedures. It is an uncommon complication of laparoscopic Roux-en-Y gastric bypass (LRGYB). The underlying etiology is assumed to be an internal hernia, in which the hernia causes lymphatic channel engorgement and lymphatic extravasation. We present the case of a 34-year-old male who had a history of LRGYB a year back and had been experiencing gradually worsening, colicky abdominal pain radiating to the right flank for the last 24 hours. Laparoscopic exploration revealed chylous ascites due to internal herniation owing to the complication of LRYGB. Classic signs of internal hernias such as mesenteric swirl were absent on the computed tomography scan of the abdomen.

Abstract
Background This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) is intended to provide clinicians an overview of bariatric surgery (i.e., bariatric procedures that improve metabolic disease are often termed "metabolic and bariatric surgery"), gastrointestinal hormones, and the microbiome as they relate to patients with obesity. Methods The scientific information for this CPS is based upon published scientific citations, clinical perspectives of OMA authors, and peer review by the Obesity Medicine Association leadership. Results This CPS includes the pros and cons of the most common types of bariatric procedures; the roles of gastrointestinal (GI) hormones in regulating hunger, digestion, and postabsorptive nutrient metabolism; and the microbiome's function and relationship with body weight. This CPS also describes patient screening for bariatric surgery, patient care after bariatric surgery, and treatment of potential nutrient deficiencies before and after bariatric surgery. Finally, this CPS explores the interactions between bariatric surgery, GI hormones, and the microbiome. Conclusions This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) regarding bariatric surgery, gastrointestinal hormones, and the microbiome is one of a series of OMA CPSs designed to assist clinicians in the care of patients with the disease of obesity. Implementation of appropriate care before and after bariatric surgery, as well as an awareness of GI hormones and the microbiome, may improve the health of patients with obesity, especially patients with adverse fat mass and adiposopathic metabolic consequences.

Abstract
Abstract
Background
To assess the role of contrast-enhanced multidetector computed tomography (MDCT) in the assessment of symptomatic patients following laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy.
Results
We reviewed the studies of 129 cases and found complications in 113 patients: 55 early complications and 48 late complications. All of these complications were diagnosed with intravenous contrast-enhanced MDCT. Statistically significant difference was found between UGIS and MDCT in the diagnosis of many cases.
Conclusion
The rate of complications in bariatric surgery is high and the associated mortality is not negligible. The interpreting radiologists should know the normal postoperative findings and be aware of possible complications.

Abstract
Although internal hernias are uncommon, they must be beared in mind in the differential diagnosis in cases of intestinal obstruction, especially in patients with no history of previous surgery or trauma. Because of the high possibility of strangulation and ischemia of the affected loops, internal hernias represent a potentially life-threatening condition and surgical emergency that needs to be quickly recognized and managed promptly. Imaging plays a leading role in the diagnosis and in particular multidetector computed tomography (MDCT), with its thin-section and high-resolution multiplanar reformatted (MPR) images, represents the first line image technique in these patients. The purpose of the present paper is to illustrate the characteristic anatomic location, the clinical findings and the CT appearance associated with main types of internal hernia, including paraduodenal, foramen of Winslow, pericecal, sigmoid-mesocolon- and trans-mesenteric-related, transomental, supravesical and pelvic hernias.

Abstract
A variety of entities may mimic drainable abscesses. This can lead to misdiagnosis of these entities, unnecessary percutaneous placement of a pigtail drainage catheter, other complications, and delay in appropriate treatment of the patient. Types of entities that may mimic drainable abscesses include neoplasms (lymphoma, gallbladder cancer, gastrointestinal stromal tumor, ovarian cancer, mesenteric fibromatosis, ruptured mature cystic teratoma, recurrent malignancy in a surgical bed), ischemia/infarction (liquefactive infarction of the spleen, infarcted splenule), diverticula (calyceal, Meckel, and giant colonic diverticula), and congenital variants (obstructed duplicated collecting system). Postoperative changes, including expected anatomy after urinary diversion or Roux-en-Y gastric bypass and small bowel resection, may also pose a diagnostic challenge. Nonpyogenic infections (Mycobacterium tuberculosis, Mycobacterium avium complex, echinococcal cysts) and inflammatory conditions such as xanthogranulomatous pyelonephritis and gossypiboma could also be misinterpreted as drainable fluid collections. Appropriate recognition of these entities is essential for optimal patient care. This article exposes radiologists to a variety of entities for which percutaneous drainage may be requested, but is not indicated, and highlights important imaging findings associated with these entities to facilitate greater diagnostic accuracy and treatment in their practice. ©RSNA, 2018.

Abstract
PURPOSE The purpose of the study is to evaluate the indications, techniques, and outcomes for percutaneous gastrostomy placement in the gastric remnant following Roux-en-Y gastric bypass (RYGB) in bariatric patients. MATERIALS AND METHODS Retrospective chart review and summary statistical analysis was performed on all RYGB patients that underwent attempted percutaneous remnant gastrostomy placement at our institution between April 2003 and November 2016. RESULTS A total of 38 patients post-RYGB who underwent gastric remnant gastrostomy placement were identified, 32 women and 6 men, in which a total of 41 procedures were attempted. Technical success was achieved in 39 of the 41 cases (95%). Indications for the procedure were delayed gastric remnant emptying/biliopancreatic limb obstruction (n = 8), malnutrition related to RYGB (n = 17), nutritional support for conditions unrelated to RYGB (n = 15), and access for endoscopic retrograde cholangiopancreatography (ERCP, n = 1). Insufflation of the gastric remnant was performed via a clear window (n = 35), transhepatic (n = 5), and transjejunal (n = 1) routes. Five complications were encountered. The four major complications (9.8%) included early tube dislodgement with peritonitis, early tube dislodgement requiring repeat intervention, intractable pain, and upper gastrointestinal bleeding. A single minor complication occurred (2.4%), cellulitis. CONCLUSION Patients with a history of RYGB present a technical challenge for excluded gastric remnant gastrostomy placement. As the RYGB population increases and ages, obtaining and maintaining access to the gastric remnant is likely to become an important part of interventional radiology's role in the management of the bariatric patient.

Abstract
OBJECTIVE To determine if the attenuation of contrast material in the excluded stomach compared with the gastric pouch is helpful in diagnosing gastrogastric (GG) fistula. MATERIALS AND METHODS In a retrospective study, 13 CT scans in 12 patients (age 43.2 ± 9.2, 10 females) who had undergone Roux-en-Y gastric bypass and who had oral contrast in both the gastric pouch and excluded stomach were qualitatively and quantitatively evaluated for GG fistula by two radiologists, using upper GI series (UGI) as the gold standard. Quantitative analysis was performed by computing the relative attenuation (RA) ratio (HU in excluded stomach/HU in gastric pouch). Statistical analysis was performed to determine if the RA ratio values correlated with the UGI findings of GG fistula. RESULTS 46.2% (6/13) of UGI studies demonstrated a GG fistula. Statistical analysis demonstrated a significant difference in RA ratio (P < 0.05) between the fistula group (1.12 ± 0.29) and the reflux group (0.56 ± 0.19). A receiver operating characteristic analysis identified an RA ratio of 0.8 that maximized sensitivity (100%), at the expense of specificity (78.6%), for diagnosing GG fistula. In contrast, the initial qualitative evaluation for GG fistula yielded a lower sensitivity (45.8%) and a higher specificity (89.2%). After taking RA ratios into account, radiologists' final conclusions achieved higher sensitivity (58.3%) and specificity (100%). CONCLUSION The relative attenuation ratio of oral contrast in the excluded stomach versus the gastric pouch can be a reliable tool in differentiating GG fistula from oral contrast reflux up the biliopancreatic limb on CT.

Abstract
BACKGROUND Gastrobronchial fistula is a rare complication in gastroesophageal surgical procedures. It is difficult to diagnose and handling is complex. Therefore, there have been developments for non-surgical alternatives to obliterate minor fistula mortality. Endoscopic treatment is an option for patients with small fistulas or in serious condition. CLINICAL CASE A 38 year old woman with evidence of gastrobronchial fistula postoperated of gastric sleeve, diagnosed during the postoperative period due to clinical variegated was initially handled as infectious respiratory symptoms; once the fistulous path was established, the intention was to close the path using endoclips. However, adding hemopneumothorax, drainage tube placement and thoracotomy were required. It was decided to chose a prosthetic esophageal endoscopic management of polytetraflouroethylene and fibrin as last therapy, because the patient had systemic inflammatory response syndrome, with favorable response to endoscopic management. DISCUSSION Bariatric surgery has shown satisfactory results, however, the complexity of the procedure favors severe complications such as the present case. Gastrobronchial fistulas represent a diagnostic and therapeutic challenge, this is considering from a conservative management to endoscopic procedures, as in our patient. CONCLUSION Although gastrobronchial fistulas are a rare complication, the use of endoscopy in resolution should be a first class weapon in its management, since it offers a lower morbidity in a patient with habitual respiratory symptoms that are difficult to control, with satisfactory results in the medium and long term.

Abstract
Both restrictive and malabsorptive types of bariatric surgery may be associated with short- and long-term complications. The lack of small bowel obstruction is not necessarily indicative of a normal study, as a variety of non-obstructed complications exist. These include stenosis at the gastrojejunostomy, leaks, abscesses, hemorrhage, internal hernias, and gastric band erosions. Radiologists should be familiar with these complications for early diagnosis and intervention before symptoms become life threatening. An understanding of the intraoperative appearances of these complications may improve imaging descriptions and add value to radiological consults for surgeons. This review provides surgical correlations to the imaging features of post-bariatric complications without obstruction of the bowel.

Abstract
Laparoscopic Roux-en-Y bypass is being increasingly used for weight reduction in patients with morbid obesity. Unfortunately, some complications can occur after this procedure, the most frequent being intestinal obstruction (due to stenosis of the anastomosis at the distal end of the loop, internal hernias, bands, and adhesions), anastomotic leaks, and bleeding. This article provides basic knowledge about the surgical technique and its correlation with the common postoperative changes with the aim of facilitating the interpretation of CT findings and the identification of postoperative complications in these patients.

Abstract
A 57-year-old woman, who had undergone Roux-en-Y gastric bypass surgery 9 years earlier, was admitted to the intensive care unit because of pneumonia. Despite antibiotic therapy, she died 40 days later, apparently because of sepsis and organ failure related to the pneumonia. However, the patient's family requested an autopsy, which revealed that her death was due to perforation of the Roux limb of her gastric bypass, which had resulted in severe peritonitis. The perforation was caused by a nasogastric tube inserted for enteral nutrition. We discuss ways nasogastric tubes might be inserted more safely after gastric bypass, the response of Baylor University Medical Center at Dallas to this complication, and the role of autopsy in improving the quality of hospital care.

Abstract
OBJETIVO: Avaliar por exame de tomografia computadorizada de pacientes submetidos à derivação gastrojejunal em Y-de-Roux, sem anel, para tratamento de obesidade mórbida. MÉTODOS: Estudaram-se 40 pacientes, encaminhados ao serviço de tomografia do Hospital Universitário Evangélico de Curitiba para avaliação diagnóstica. Encontravam-se em pós-operatório de cirurgia bariátrica tendo sido operados no mesmo hospital. Foram incluídos pacientes submetidos à operação laparoscópica com sintomas que necessitavam de avaliação tomográfica diagnóstica. Excluíram-se pacientes que tinham sido submetidos à cirurgia bariátrica por outras técnicas cirúrgicas; que tinham sido operados por outra equipe; que não concordassem com a administração de contraste iodado por via oral ou endovenosa; e que excediam o limite de peso da mesa de exame. Para análise estatística utilizou-se a média das variáveis. RESULTADOS: Os pacientes apresentaram-se com idade entre 23 a 70 anos e eram 11 homens e 29 mulheres. Não houve alterações extra-abdominais detectáveis pela tomografia de abdômen total; dos 40 pacientes avaliados, 30 apresentavam achados tomográficos dentro do limite da normalidade. A presença de estenose na anastomose gastrojejunal foi encontrada em um paciente; hérnia interna ocorreu em cinco; fístula anastomótica em um e abcesso em três dos pacientes estudados. CONCLUSÃO: A tomografia de abdome total não conseguiu informar a causa dos sintomas dos pacientes operados em 87,5% dos pacientes que procuraram re-avaliação médica por sintomas pós-operatórios da cirurgia bariátrica.

Abstract
Gastrobronchial fistula (GBF) is a serious complication following bariatric surgery, whose treatment by thoracotomy and/or laparotomy involves a high morbidity rate. We present the outcomes of endoscopic management for GBF as a helpful technique for its healing process. This is a multicenter retrospective study of 15 patients who underwent gastric bypass (n = 10) and sleeve gastrectomy (n = 5) and presented GBF postoperatively (mean of 6.7 months). Ten patients developed lung abscess and were treated by antibiotic therapy (n = 10) and thoracotomy (n = 3). Abdominal reoperation was performed in nine patients for abscess drainage (n = 9) and/or ring removal (n = 4) and/or nutritional access (n = 6). The source of the GBF was at the angle of His (n = 14). Furthermore, 14 patients presented a narrowing of the gastric pouch treated by 20 or 30 mm aggressive balloon dilation (n = 11), stricturotomy or septoplasty (n = 10) and/or stent (n = 7). Fibrin glue was used in one patient. We performed, on average, 4.5 endoscopic sessions per patient. Endotherapy led to a 93.3% (14 out of 15) success rate in GBF closure with an average healing time of 4.4 months (range, 1-10 months), being shorter in the stent group (2.5 × 9.5 months). There was no recurrence during the average 27.3-month follow-up. A patient persisted with GBF, despite the fibrin glue application, and decided to discontinue it. GBF is a highly morbid complication, which usually arises late in the postoperative period. Endotherapy through different strategies is a highly effective therapeutic option and should be implemented early in order to shorten leakage healing time.

Abstract
BACKGROUND Four different types of internal hernias (IH) are known to occur after laparoscopic Roux-en-Y gastric bypass (LRYGBP) performed for morbid obesity. We evaluate multidetector row helical computed tomography (MDCT) features for their differentiation. METHODS From a prospectively collected database including 349 patients with LRYGBP, 34 acutely symptomatic patients (28 women, mean age 32.6), operated on for IH immediately after undergoing MDCT, were selected. Surgery confirmed 4 (11.6%) patients with transmesocolic, 10 (29.4%) with Petersen's, 15 (44.2%) with mesojejunal, and 5 (14.8%) with jejunojejunal IH. In consensus, 2 radiologists analyzed 13 MDCT features to distinguish the four types of IH. Statistical significance was calculated (p<0.05, Fisher's exact test, chi-square test). RESULTS MDCT features of small bowel obstruction (SBO) (n=25, 73.5%), volvulus (n=22, 64.7%), or a cluster of small bowel loops (SBL) (n=27, 79.4%) were inconsistently present and overlapped between the four IH. The following features allowed for IH differentiation: left upper quadrant clustered small bowel loops (p<0.0001) and a mesocolic hernial orifice (p=0.0003) suggested transmesocolic IH. SBL abutting onto the left abdominal wall (p=0.0021) and left abdominal shift of the superior mesenteric vessels (SMV) (p=0.0045) suggested Petersen's hernia. The SMV predominantly shifted towards the right anterior abdominal wall in mesojejunal hernia (p=0.0033). Location of the hernial orifice near the distal anastomosis (p=0.0431) and jejunojejunal suture widening (p=0.0005) indicated jejunojejunal hernia. CONCLUSIONS None of the four IH seems associated with a higher risk of SBO. Certain MDCT features, such as the position of clustered SBL and hernial orifice, help distinguish between the four IH and may permit straightforward surgery.

Abstract
The role of surgery in the morbidly obese is becoming more prominent. There are a variety of surgical approaches which can be used and radiology plays a crucial role in post operative follow up, particularly in the management of complications. Many general radiologists remain unfamiliar with both the normal and abnormal appearances after bariatric surgery and this pictorial review aims to bridge this gap.

Abstract
BACKGROUND Obesity is becoming epidemic in proportion and is leading to considerable morbidity and mortality in the community. Bariatric surgery offers one tested solution to sustained weight loss and comorbidity reduction. However, it is associated with a significant number of complications. OBJECTIVE The objective of this article is to review the utility of radiological techniques in the diagnosis of surgical complications after bariatric surgery. DESIGN Literature-based review and pictorial illustration in the use of imaging techniques in the diagnosis of complications after bariatric surgery. CONCLUSIONS Radiology plays a critical role in the diagnosis of complications after bariatric surgery. Upper GI contrast study and CT are the most commonly used imaging modalities in this regard. They are complementary in their diagnostic abilities and should be used in concert for the complete evaluation of symptomatic patients. All other radiological imaging modalities are also used in the diagnosis of complications after bariatric surgery, but much less commonly.

Abstract
BACKGROUND The purpose of this study was to estimate the cumulative radiation dose from computed tomography (CT) scans and upper gastrointestinal fluoroscopic exams in the post-bariatric-surgery population and correlate these values with current concepts of potential radiation-induced cancer risk. METHODS A retrospective study of 100 roux-en-y gastric bypass (RYGB) patients and 100 gastric band patients was performed. The cumulative estimated radiation doses from CT scans and fluoroscopic studies received by these patients over a 2.5-year postoperative interval were calculated. The rate of positive radiological studies was determined. Nonlinear regression analyses were used to identify potential independent predictors of higher radiation dose. RESULTS Mean cumulative dose was 20 +/- 20 mSv for RYGB patients and 11 +/- 11 mSv for gastric band patients. The RYGB procedure and a higher preoperative body mass index were each significant predictors of higher cumulative radiation doses. Dose in the RYGB group ranged from 4 to 156 mSv. Dose in the gastric banding group ranged from 4 to 46 mSv. In the RYGB cohort, positive findings were present in 35% and 16% of CT and fluoroscopic studies, respectively, and 24% and 22% in the gastric band group. None of the fluoroscopic exams performed after the routine 24-h postoperative studies were positive. CONCLUSIONS Allowing for uncertainties of cancer risk at doses less than 50 mSv, patients undergoing laparoscopic bariatric surgery may receive radiation doses from postoperative diagnostic imaging tests that increase their lifetime cancer risk.

Abstract
PURPOSE The purpose of this study was to review the etiology and computed tomography (CT) findings of small-bowel obstruction (SBO) in patients who have undergone bariatric laparoscopic Roux-en-Y gastric bypass (LGBP) surgery. MATERIALS AND METHODS Prospectively entered data from a surgical database of 835 consecutive patients who underwent antecolic-antegastric LGBP for morbid obesity from June 1999 to April 2005 in a single institution were retrospectively reviewed. A total of 42 cases of bowel obstruction were observed in 41 patients. Surgical proof was available in 38 cases, and 4 cases had characteristic imaging features and/or clinical follow-up. Seventeen CT scans were reviewed to determine cause and level of obstruction, and this was correlated with surgical findings and clinical follow-up. RESULTS Internal hernia was the most common (13 cases) and also the most frequently missed etiology of SBO on CT scans, with the diagnosis being made prospectively in only 2 of 6 cases, in which CT was done. Adhesions, ventral hernia, postoperative ileus, and jejunojejunal (JJ) anastomotic strictures, in that order, were the other commonly observed etiologies for SBO, with 11, 7, 5, and 4 cases, respectively. Some causes of SBO post-LGBP (JJ anastomotic stricture and postoperative ileus) developed relatively early, whereas others (internal hernia) tended to develop later or had a bimodal distribution (adhesions and ventral hernia). Fifteen (36%) of 42 cases had SBO at or near the level of jejunojejunostomy site; causes included internal hernia (5 cases), adhesions/kinking of small bowel (5 cases), JJ anastomotic stricture (4 cases), and JJ intussusception (1 case). CONCLUSION The time interval between LGBP and development of SBO might provide a useful clinical clue to its etiology. The JJ level is an important location for SBO post-LGBP because of a variety of causes, and special attention must be paid to this site at imaging of post-LGBP patients.

Abstract
This is a case of a 33 weeks pregnant woman, presented 2 years after laparoscopic Roux-en-Y gastric bypass, with abdominal pain for 2 days. A laparoscopic cholecystectomy was performed 1 day earlier in another hospital, without improving the pain. She presented at our hospital with acute abdominal pain and clinical signs of intestinal obstruction, undergoing an exploratory laparotomy that revealed a volvulus and necrosis of the jejunum from the gastroenteroanastomosis through the lateral enteroenterostomy, which was resected with the reconstruction of the Roux-en-Y limb performed at the same operation. Patient and neonate presented with improvement after surgery and the patient was discharged on postoperative day 15. Internal hernias after bariatric surgery have been reported as the cause of acute abdomen problems during pregnancy, which may progress to necrosis and perforation. The delay of surgical intervention could have brought a tragic outcome for mother and neonate.

Abstract
PURPOSE To retrospectively evaluate the imaging features at upper gastrointestinal (GI) examination of leak into the excluded part of the stomach after the Roux-en-Y gastric bypass (RYGB) procedure and to determine the associated complications and consequences of acute versus delayed leak development. MATERIALS AND METHODS The institutional review board approved this HIPAA-compliant study; the need for informed consent was waived. Database review revealed 1655 upper GI studies performed over 6 years in 1282 patients after an RYGB procedure. Leak into the excluded stomach was diagnosed in 48 patients (39 women, nine men; age range, 29-62 years; mean age, 46 years); these patients formed our study group. Studies were analyzed by two radiologists in consensus for extent and pattern of leak into the excluded stomach and the presence of associated complications of extraluminal leak or fistula, obstruction, and acute distention of the excluded stomach. Chart review was performed to determine clinical course, treatment, associated complications, and outcome. Patients were divided into two categories on the basis of acute versus delayed development of leak into the excluded stomach. Acute leak into the excluded stomach was diagnosed within 2 months of surgery. Delayed leak occurred more than 2 months after surgery. RESULTS Leak into the excluded stomach occurred in the acute postoperative period (within 2 months) in 25 of the 48 patients (52%) and was associated with extraluminal leak in 22 of those 25 patients (88%). Acute leak into the excluded stomach healed in seven of the 25 patients (28%). Delayed postoperative leak into the excluded stomach occurred in 23 of the 48 patients (48%) and resulted in failed weight loss in 14 of those 23 patients (61%). Fourteen of the 48 patients (29%) underwent surgical revision for leak into the excluded stomach. CONCLUSION Leak into the excluded stomach was identified on upper GI studies in 48 of 1282 patients (3.7%) after RYGB for morbid obesity. Acute leak into the excluded stomach may heal spontaneously; however, remote postoperative leak into the excluded stomach can result in failed weight loss and subsequent failure of the RYGB procedure.

Abstract
LEARNING OBJECTIVES To describe normal anatomy of Roux-en-Y gastric bypass (GBP) surgery. To know the spectrum of major complications, time of appearance and imaging findings. BACKGROUND Roux-en-Y GBP surgery nowadays represents a successful treatment of morbid obesity. From January 1999 to June 2005, 148 patients with Roux-en-Y GBP surgery have been reviewed. Within a period of 24-72 h after surgery, upper gastrointestinal series was performed. The radiographic manifestations of normal anatomy and follow-up major complications are illustrated in this pictorial essay. We compare the CT and other imaging findings with clinical and surgical findings. IMAGING FINDINGS A total of 14 follow-up major complications occurred in 9 of 148 patients. Only 3 were early complications, the other 11 were late and appeared between 1 month and 4 years. Imaging findings of stomal stenosis, gastric staple line dehiscence, leaks, jejunal and gastric wall necrosis, small bowel obstruction due to adhesions, loculated fluid collection and celiac trunk stenosis are illustrated. CONCLUSION It is important for the radiologist to be familiarized with the radiographic manifestations of normal anatomy and major complications after Roux-en-Y GBP. These may be life-threatening and usually appear as late complications. An adequate imaging technique and a prompt evaluation by the radiologist can help to minimize them.

Abstract
Gastrobronchial fistula is a rare condition as a complication following bariatric surgery. The management of this condition requires the active participation of a pulmonologist, who should be familiar with aspects of the main types of bariatric surgery. Herein, we report the cases of two patients who presented recurrent subphrenic and lung abscess secondary to fistula at the angle of His for an average of 19.5 months. After relaparotomy was unsuccessful, cure was achieved by antibiotic therapy and, more importantly, by stenostomy and endoscopic dilatation, together with the use of clips and fibrin glue in the fistula. These pulmonary complications should not be treated in isolation without a gastrointestinal evaluation since this can result in worsening of the respiratory condition, thus making anesthetic management difficult during endoscopic procedures.

Abstract
BACKGROUND To report the prognosis and management of patients reoperated for severe intraabdominal sepsis (IAS) after bariatric surgery (S0) and admitted to the surgical intensive care unit (ICU) for organ failure. METHODS A French observational study in a 12-bed adult surgical intensive care unit in a 1,200-bed teaching hospital with expertise in bariatric surgery. From January 2001 to August 2006, 27 morbidly obese patients (18 transferred from other institutions) developed severe postoperative IAS (within 45 days). Clinical signs, biochemical and radiologic findings, and treatment during the postoperative course after S0 were reviewed. Time to reoperation, characteristics of IAS, demographic data, and disease severity scores at ICU admission were recorded and their influence on prognosis was analyzed. RESULTS The presence of respiratory signs after S0 led to an incorrect diagnosis in more than 50% of the patients. Preoperative weight (body mass index [BMI] > 50 kg/m2) and multiple reoperations were associated with a poorer prognosis in the ICU. The ICU mortality rate was 33% and increased with the number of organ failures at reoperation. CONCLUSION During the initial postoperative course after bariatric surgery, physical examination of the abdomen is unreliable to identify surgical complications. The presence of respiratory signs should prompt abdominal investigations before the onset of organ failure. An urgent laparoscopy, as soon as abnormal clinical events are detected, is a valuable tool for early diagnosis and could shorten the delay in treatment.

Abstract
Despite the advantages offered by laparoscopy in bariatric surgery, the incidence of a new complication that was uncommon in the previous era of open surgery--internal hernias--has increased. Most publications in the literature dealing with internal hernia describe the incidence and form of presentation of this entity but few explain how these complications can be prevented. In this review article we describe a technique to close mesenteric defects in retrocolic Roux-en-Y laparoscopic gastric bypass with permanent, continuous running suture (ethibond). We also review the literature in MEDLINE (www.ncbi.nlm.nih.gov/entrez/ using the key words: obesity, laparoscopy, gastric bypass, internal hernia, Petersen hernia) and references from articles of interest to determine the real incidence of this complication. Our technique has proven to be safe, reliable and reproducible and has greatly diminished the incidence of internal hernias. However, our data need to be analyzed in the future to determine whether the technique described eliminates this complication. The optimal results achieved with complete closure of all mesenteric defects have also been observed by other authors.

Abstract
BACKGROUND The use of postoperative upper GI series (UGIS) after laparoscopic Roux-en-Y gastric bypass (LRYGBP) varies among bariatric surgeons. The authors describe the findings and impact of UGIS after LRYGBP. METHODS From July 2003 to January 2006, 487 patients undergoing primary LRYGBP at a single academic institution had a single-contrast Gastrografin UGIS performed on the first postoperative day, without complication. Patient and operative demographics were: mean age 43 years, mean BMI 47 kg/m2, female 84%, and laparoscopic 100%. RESULTS Of the 487 patients, the UGIS revealed 14 (2.9%) major and 88 (15.2%) minor abnormalities. Among the major UGIS abnormalities, 6 (1.2%) demonstrated a gastrojejunal anastomotic (GJA) leak, 8 (1.4%) confirmed complete obstruction at the GJA, and 1 (0.2%) disclosed a communication with the bypassed stomach. For the minor UGIS abnormalities, 45 (9.2%) displayed significant delay in contrast passage through the GJA, 23 (5.0%) had evidence of dilated loops of small and/or large bowel, and 6 (1.2%) verified miscellaneous abnormal findings (malrotation, lower esophageal dysmotility, jejunal clots). Patients with UGIS abnormalities necessitated additional procedures, delayed oral intake and/or longer length of stay (LOS). CONCLUSIONS UGIS on postoperative day 1 is a useful means of evaluating postoperative LRYGBP anatomy and influenced postoperative care.

Abstract
BACKGROUND Anastomotic stenosis presents as one of the most common late complications in the postoperative period after bariatric surgery. It is often diagnosed by upper gastrointestinal series (UGIS) and/or upper endoscopy (UE). The aim of this study was to determine whether a correlation exists between the Gastrografin UGIS and UE findings in the determination of gastrojejunal anastomotic strictures after Roux-en-Y gastric bypass (RYGB). METHODS Between July 2001 and October 2003, all medical records of patients who underwent RYGB at our institution were retrospectively reviewed. The medical records of patients who underwent UE because of symptoms suggestive of gastric outlet obstruction and those of patients who were initially evaluated by Gastrografin UGIS before UE were evaluated further. RESULTS Of 535 morbidly obese patients who underwent RYGB, 52 (9.7%) had UE and were included in this study. The mean number of UEs performed per patient was 2.67. Of these 52 patients, 30 underwent Gastrografin UGIS before UE. The mean diameter of the anastomosis on the first UE was 5.97 mm and on Gastrografin UGIS was 6.83 mm. A good correlation was found between the Gastrografin UGIS and UE findings using Pearson's correlation coefficient (0.44, P = .02) and single linear regression analysis using the endoscopic diameter as the outcome and radiographic findings as the predictor (beta = 0.27, P = .025, 95% confidence interval 0.30-0.49). CONCLUSION In our study, the Gastrografin UGIS findings correlated positively with the endoscopic gastrojejunal anastomosis findings in patients with anastomotic stricture who had undergone RYGB.

Abstract
OBJECTIVE Internal hernias, including paraduodenal (traditionally the most common), pericecal, foramen of Winslow, and intersigmoid hernias, account for approximately 0.5-5.8% of all cases of intestinal obstruction and are associated with a high mortality rate, exceeding 50% in some series. To complicate matters, the incidence of internal hernias is increasing because of a number of relatively new surgical procedures now being performed, including liver transplantation and gastric bypass surgery. A significant increase in hernias is occurring in patients undergoing transmesenteric, transmesocolic, and retroanastomotic surgical procedures. It is important for radiologists to be familiar with and to understand the various types of internal hernias and their imaging features so that prompt and accurate diagnosis of these conditions can be made. CONCLUSION This article illustrates the imaging findings of internal hernias, with emphasis placed on the CT findings, especially in transmesenteric, transmesocolic, and retroanastomotic types of internal hernias.

Diagnosis and management of partial small bowel obstruction after laparoscopic antecolic antegastric Roux-en-Y gastric bypass for morbid obesity. J Am Coll Surg 2006; 202:262-8. [PMID: 16427551 DOI: 10.1016/j.jamcollsurg.2005.10.018] [Citation(s) in RCA: 43] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2005] [Revised: 10/11/2005] [Accepted: 10/26/2005] [Indexed: 01/04/2023]
Abstract
BACKGROUND The resultant derangement of the normal gastrointestinal anatomy after a gastric bypass procedure increases the incidence of, and level of difficulty diagnosing, partial small bowel obstruction (SBO) in morbidly obese patients. We evaluated the diagnostic methods for partial SBO and the clinical characteristics according to the time after initial operation. STUDY DESIGN Data of 1,400 consecutive patients who underwent antecolic antegastric laparoscopic Roux-en-Y gastric bypass between 2001 and 2004 were retrospectively analyzed. RESULTS Partial SBO developed in 21 (1.5%) patients after laparoscopic Roux-en-Y gastric bypass. Five of 15 patients were preoperatively diagnosed with SBO by a gastrograffin study and CT scan diagnosed 17 of 19 patients (p = 0.002). Causes of SBO included jejunojejunostomy stenosis (n = 6), adhesions (n = 5), incarcerated ventral hernia (n = 5), internal hernia (n = 3), and other (n = 2). The majority of patients (n = 19) underwent surgical treatment. CONCLUSIONS The most frequent cause of early SBO is jejunojejunal anastomotic stenosis. CT scan is a more accurate diagnostic tool for detecting partial SBO, compared with use of a gastrograffin study. Operation remains the most appropriate and definitive treatment for this complication and the laparoscopic approach is a feasible and safe surgical treatment option.
