RESUMEN
BACKGROUND: This systematic review and meta-analysis assessed the effectiveness of robotic surgery compared to laparoscopy or open surgery for inguinal (IHR) and ventral (VHR) hernia repair. METHODS: PubMed and EMBASE were searched up to July 2022. Meta-analyses were performed for postoperative complications, surgical site infections (SSI), seroma/hematoma, hernia recurrence, operating time (OT), intraoperative blood loss, intraoperative bowel injury, conversion to open surgery, length of stay (LOS), mortality, reoperation rate, readmission rate, use of opioids, time to return to work and time to return to normal activities. RESULTS: Overall, 64 studies were selected and 58 were used for pooled data analyses: 35 studies (227 242 patients) deal with IHR and 32 (158 384 patients) with VHR. Robotic IHR was associated with lower hernia recurrence (OR 0.54; 95%CI 0.29, 0.99; I2: 0%) compared to laparoscopic IHR, and lower use of opioids compared to open IHR (OR 0.46; 95%CI 0.25, 0.84; I2: 55.8%). Robotic VHR was associated with lower bowel injuries (OR 0.59; 95%CI 0.42, 0.85; I2: 0%) and less conversions to open surgery (OR 0.51; 95%CI 0.43, 0.60; I2: 0%) compared to laparoscopy. Compared to open surgery, robotic VHR was associated with lower postoperative complications (OR 0.61; 95%CI 0.39, 0.96; I2: 68%), less SSI (OR 0.47; 95%CI 0.31, 0.72; I2: 0%), less intraoperative blood loss (- 95 mL), shorter LOS (- 3.4 day), and less hospital readmissions (OR 0.66; 95%CI 0.44, 0.99; I2: 24.7%). However, both robotic IHR and VHR were associated with significantly longer OT compared to laparoscopy and open surgery. CONCLUSION: These results support robotic surgery as a safe, effective, and viable alternative for IHR and VHR as it can brings several intraoperative and postoperative advantages over laparoscopy and open surgery.

INTRODUCTION: Parastomal hernias are a challenging complication of digestive ostomies. Ileal-conduit parastomal hernias after cystectomy have specific aspects. The aim of this study was to describe the incidence and natural history of ileal-conduit parastomal hernias in order to guide their management, as well as to identify risk factors to prevent them. PATIENTS AND METHODS: All consecutive patients undergoing cystectomy with a Bricker's ileal conduit in 3 academic centers were retrospectively identified. Data were collected regarding their medical history prior to cystectomy, the operation, the postoperative period, imaging results within 5 years of follow-up, and the onset and timing of clinically or radiologically diagnosed ICPH. RESULTS: Among 577 patients included in the study, 115 (20.6%) developed an ICPH during the study period. Most patients did not present any symptom and the diagnosis was made at imaging in 74.8% of them. Most hernias were detected between 1 and 2 years after the cystectomy, with a mean time to diagnosis of 12.4 months. At multivariate analysis, overweight and obesity were independent risk factors for developing an ICPH (adjusted hazard ratio [aHR] 1.96; p = 0.046), while a trans-rectus position of the ostomy was a significant protective factor (aHR 0.45; p = 0.011). CONCLUSIONS: A PH develops in almost 20% of patients after ileal conduit urinary diversion, with a mean time of onset of 12.4 months. It is often a subclinical condition detected at medical imaging. Obesity increases the risk, while passing the ileal-conduit through the rectus muscle can help to prevent it.

BACKGROUND: Parastomal incisional hernia (PH) is a frequent complication following the creation of an ileal conduit (IC), and it can be a significant detriment to quality of life. The aim of this study was to evaluate outcomes of PH repair following IC for urinary diversion. METHOD: A multicenter retrospective study was conducted of 6 academic hospitals in France. The study's population included patients who underwent surgical treatment for parastomal hernia following IC creation from 2013 to 2021. RESULTS: Fifty-one patients were included in the study. Median follow up was 15.3 months. Eighteen patients presented with a recurrence (35%), with a median time to recurrence of 11.1 months. The vast majority of PH repair was performed through an open approach (88%). With regard to technique, Keyhole was the most reported technique (46%) followed by Sugarbaker (22%) and suture only (20%). The Keyhole technique was associated with a higher risk of recurrence compared to the Sugarbaker technique (52% vs 10%, p = 0.046). Overall, there was a 7.8% rate of major complications without a statistical difference between PH repair techniques for major complications. CONCLUSION: Surgical treatment of parastomal hernia following IC was associated with a high risk of recurrence. Novel surgical approaches to PH repair should be considered.

BACKGROUND AND AIMS: There has been interest in the use of pyloric therapies for the treatment of refractory gastroparesis. However, data on endoscopic pyloric dilation are scarce. We aimed to assess the efficacy and safety of this procedure in refractory gastroparesis. METHODS: We performed a retrospective analysis of 47 patients referred for refractory gastroparesis, confirmed by gastric emptying scintigraphy, and treated with endoscopic pyloric through-the-scope balloon dilation. The primary endpoint was the effectiveness of the procedure, evaluated with the Gastric Cardinal Symptom Index (GCSI) at 2 and 6 months. RESULTS: A clinical response, defined by a 1.0 point decrease in the GCSI score, was observed in 25 patients at 2 months (53%) and in 19 patients at 6 months (40%). The mean GCSI score decreased significantly at 2 and 6 months compared to the preoperative score (3.9 ± 0.87 vs 2.3 ± 1.37 and 3.9 ± 0.87 vs 2.9 ± 1.27, respectively; p < 0.0001). No complication was observed. Nine patients had a delayed relapse at 1 year. A second dilation was performed for eight patients and it was effective in five of them (63%). The mean follow-up time of the patients was 27.0 ± 10.4 months. At 2 years, 15 patients still experienced improvement following this treatment (32%). No predictive factor of clinical response was identified. CONCLUSION: The efficacy of pyloric dilation is 53% at 2 months, with sustained improvement in one third of patients at 2 years. This treatment should be considered as an alternative option to pyloromyotomy.

OBJECTIVE: To perform a retrospective root-cause analysis of postoperative death after CRS and HIPEC procedures. BACKGROUND: The combination of CRS and HIPEC is an effective therapeutic strategy to treat peritoneal surface malignancies, however it is associated with significant postoperative mortality. METHODS: All patients treated with a combination of CRS and HIPEC between January 2009 and December 2018 in 22 French centers and died in the hospital, were retrospectively analyzed. Perioperative data of the 101 patients were collected by a local senior surgeon with a sole junior surgeon. Three independent experts investigated the typical root cause of death and provided conclusions on whether postoperative death was preventable (PREV group) or not (NON-PREV group). A typical root cause of preventable postoperative death was classified on a cause-and-effect diagram. RESULTS: Of the 5562 CRS+HIPEC procedures performed, 101 in-hospital deaths (1.8%) were identified, of which a total of 18 patients of 70âyears old and above and 20 patients with ASA score of 3. Etiology of peritoneal disease was mainly colorectal. A total of 54 patients (53%) were classified in the PREV group and 47 patients (47%) in the NON-PREV group. The results of the study show that in the PREV group, WHO performance status 1-2 was more frequent and the Median Peritoneal Cancer Index was higher compared with those of the NON-PREV group. The cause of death in the PREV group was classified as: (i) preoperatively for debatable indication (59%), (ii) intraoperatively (30%) and (iii) postoperatively in 17 patients (31%). A multifactorial cause of death was found in 11 patients (20%). CONCLUSION: More than half of the postoperative deaths after combined CRS and HIPEC may be preventable, mainly by following guidelines regarding preoperative selection of the patients and adequate intraoperative decisions.

BACKGROUND: Bariatric surgery is associated with decreased cancer-related mortality. An indefinite proportion of patients that undergo bariatric surgery have a history of malignancy or will develop cancer. In these patients, weight loss and oncologic evolution needed to be assessed. The aim of this study was to report the results of patients diagnosed with malignancy before and after bariatric surgery in a French multisite cohort. METHODS: We conducted a retrospective cohort study of all patients who underwent bariatric surgery in six university centers. Patients were divided in two groups: patients with a preoperative history of malignancy and patients diagnosed with malignancy during the follow-up. Both groups were compared with control groups of patients that underwent surgery during the same period. RESULTS: From 2008 to 2018, 8927 patients underwent bariatric surgery. In patients with a history of malignancy (n = 90), breast and gynecologic cancers were predominant (37.8%). Median interval between malignancy and surgery was 60 (38-118) months. After a follow-up of 24 (4-52) months, 4 patients presented with cancer recurrence. Comparative analysis demonstrated equivalent weight loss one year after surgery. In patients with postoperative malignancy (n = 32), breast and gynecologic cancers were also predominant (40.6%). Median interval between surgery and malignancy was 22 (6-109) months. In the comparative analysis, weight loss was similar at 2 years. CONCLUSIONS: History of malignancy should not be considered as an absolute contraindication for bariatric surgery. Gynecological cancer screening should be reinforced before and after surgery. The development of malignancy postoperatively does not seem to affect mid-term bariatric outcomes.

INTRODUCTION: The aim of the present study was to describe autonomic urethral sphincter (US) innervation using specific muscular and neuronal antibody markers and 3D reconstruction. MATERIAL AND METHODS: We performed en-bloc removal of the entire pelvis of three male human fetuses between 18 and 40 weeks. Serial whole mount sections (5 µm intervals) were stained and investigated. The sections were stained with Masson's trichrome and Eosin Hematoxylin, and immunostained with: anti-SMA antibody for smooth muscle; anti-S100 antibody for all nerves; and anti-PMP22 antibody, anti-TH antibody, anti-CGRP antibody, anti-NOS antibody for somatic, adrenergic, sensory and nitrergic nerve fibers, respectively. The slides were digitized for 3D reconstruction to improve topographical understanding. An animated reconstruction of the autonomic innervation of the US was generated. RESULTS: The external and internal US are innervated by autonomic nerves of the inferior hypogastric plexus (IHP). These nerves are sympathetic (positive anti-TH antibody), sensory (positive anti-CGRP antibody), and nitrergic (positive anti-NOS antibody). Some autonomic fibers run within the neurovascular bundles, posterolaterally. Others run from the IHP to the posteromedial aspect of the prostate apex, above an through the rectourethral muscle. The external US is also innervated by somatic nerves (positive anti-PMP22 antibody) arising from the pudendal nerve, joining the midline but remaining below the rectourethral. CONCLUSIONS: This study provides anatomical evidence of an autonomic component in the innervation of the external US that travels in the neurovascular bundle. During radical prostatectomy, the rectourethral muscle and the neurovascular bundles are to be preserved, particularly during apical dissection.

BACKGROUND: Incisional hernia (IH) may occur in 20% of patients after laparotomy. The hernia sac volume may be of significance, with reintegration of visceral contents potentially leading to repair failure or abdominal compartment syndrome. The present study aimed to evaluate a two-step surgical strategy comprising right colectomy for hernia reduction with synchronous absorbable mesh repair followed by definitive non-absorbable mesh repair in recurrence. METHODS: Patients operated between 2012 and 2017 at two university centers were retrospectively included. Volumetric evaluation of the IH was performed by CT imaging. RESULTS: Eleven patients were included. The mean BMI was 43 kg/m2 (23-52 kg/m2). Progressive preoperative pneumoperitoneum was performed in 82% of patients, with complications in 22%. The mean volumetric ratio of the volume of the hernia to the volume of the abdominal cavity was 70% (48-100%). The first parietal repair was performed using an synthetic absorbable mesh (36%), a biologic mesh (27%), or a slowly absorbable mesh (36%). No patients died as a result of the procedure. Seven (64%) patients developed grade III-IV complications, including one case of an anastomotic fistula. Recurrence occurred in eight (73%) patients after the first repair. Of these, four (50%) patients were reoperated using a non-absorbable mesh, leading to solid repair in 75% of cases. After 27 ± 18 months of follow-up, the residual IH rate was 46%. CONCLUSIONS: Right colectomy for volume reduction in IH with loss of domain potentially represents an appropriate salvage option, supporting bowel reintegration and temporary hernia repair with absorbable material.

BACKGROUND: There are no specific guidelines for ventral hernia management in Crohn's disease (CD) patients. We aimed to assess the risk of septic morbidity after mesh repair in CD. METHODS: This was a retrospective multicentre study comparing CD and non-CD patients undergoing mesh repair for ventral hernia (primary or incisional hernia). Controls were matched 1:1 for the presence of a stoma, history of surgical sepsis, hernia size and Ventral Hernia Working Group (VHWG) score. All demographic, pre-, intra- and postoperative data were retrieved, including long-term data. RESULTS: We included 234 patients, with 114 CD patients. Both groups had comparable VHWG scores (p = 0.12), hernia sizes (p = 0.11), ASA scores ≥ 3 (p = 0.70), body mass index values (p = 0.14), presence of stoma (CD 21.9% vs. controls 15%, p = 0.16), history of sepsis (14% vs. 6.7%, p = 0.23), rates of malnutrition (4.4% vs. 1.7%, p = 0.46), rates of incisional hernia (93% vs. 95%, p = 0.68) and concomitant procedures (18.4% vs. 11.7%, p = 0.12). CD patients carried a higher risk of postoperative septic morbidity (18.4% vs. 5%, p = 0.001), entero-prosthetic fistula (7% vs. 0, p < 0.01) and mesh withdrawals (5.3% vs. 0, p = 0.011). Ventral hernia recurrence rates were similar (14% vs. 8.3%, p = 0.15). In the univariate analysis, the risk factors for septic morbidity were CD (p = 0.001), malnutrition (p = 0.004), use of biological mesh (p < 0.0001) and concomitant procedure (p = 0.004). The mesh position, the means used for mesh fixation as well as the presence of a stoma were not identified as risk factors. CONCLUSIONS: CD seems to be a risk factor for septic morbidity after mesh repair.

The outbreak of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 infection has recently spread globally and is now a pandemic. As a result, university hospitals have had to take unprecedented measures of containment, including asking nonessential staff to stay at home. Medical students practicing in the surgical departments find themselves idle, as nonurgent surgical activity has been canceled, until further notice. Likewise, universities are closed and medical training for students is likely to suffer if teachers do not implement urgent measures to provide continuing education. Thus, we sought to set up a daily medical education procedure for surgical students confined to their homes. We report a simple and free teaching method intended to compensate for the disappearance of daily lessons performed in the surgery department using the Google Hangouts application. This video conference method can be applied to clinical as well as anatomy lessons.

The risk of developing an abdominal wall hernia is high in the cirrhotic patient, due to the association of ascites, hypoalbuminemia and amyotrophy in connection with undernutrition frequently associated with cirrhosis. Thus, almost 20% of cirrhotic patients develop an umbilical hernia. Parietal surgery is more at risk in cirrhotic patients and its indications must be discussed on a case-by-case basis. The objective of this work was to review the entire literature on wall surgery in order to best define the surgical indications and the specifics of their management. The bibliographic research was done on Pubmed over the period from January 1995 to December 2019, using French and English as publication languages. The keywords retained were "hernia" [Mesh] and "liver cirrhosis" [Mesh]. In an elective situation, preoperative ascites control is recommended. A parietal prosthesis can be used, even in the case of uninfected ascites, preferably in the retromuscular position. Laparoscopy should be used with caution, due to the bleeding risk. No recommendation can be made on the use of prophylactic intra-abdominal drainage. The literature data do not allow the trans-jugular route portosystemic shunt recommendation, nor the use of a peritoneal-vesical pump to decrease the volume of ascites before parietal surgery in cirrhotic patients.

BACKGROUND: Injury to the levator ani muscle or pelvic nerves during pregnancy and vaginal delivery is responsible for pelvic floor dysfunction. OBJECTIVE: We sought to demonstrate the presence of smooth muscular cell areas within the levator ani muscle and describe their localization and innervation. STUDY DESIGN: Five female human fetuses were studied after approval from the French Biomedicine Agency. Specimens were serially sectioned and stained by Masson trichrome and immunostained for striated and smooth muscle, as well as for somatic, adrenergic, cholinergic, and nitriergic nerve fibers. Slides were digitized for 3-dimensional reconstruction. One fetus was reserved for electron microscopy. We explored the structure and innervation of the levator ani muscle. RESULTS: Smooth muscular cell beams were connected externally to the anococcygeal raphe and the levator ani muscle and with the longitudinal anal muscle sphincter. The caudalmost part of the pubovaginal muscle was found to bulge between the rectum and the vagina. This bulging was a smooth muscular interface between the levator ani muscle and the longitudinal anal muscle sphincter. The medial (visceral) part of the levator ani muscle contained smooth muscle cells, in relation to the autonomic nerve fibers of the inferior hypogastric plexus. The lateral (parietal) part of the levator ani muscle contained striated muscle cells only and was innervated by the somatic nerve fibers of levator ani and pudendal nerves. The presence of smooth muscle cells within the medial part of the levator ani muscle was confirmed under electron microscopy in 1 fetus. CONCLUSION: We characterized the muscular structure and neural control of the levator ani muscle. The muscle consists of a medial part containing smooth muscle cells under autonomic nerve influence and a lateral part containing striated muscle cells under somatic nerve control. These findings could result in new postpartum rehabilitation techniques.

BACKGROUND: The American College of surgical risk calculator (SRC) score has never been validated specifically for surgery in emergency. The objective was to evaluate the reliability of this calculator in patients with malignant colon obstruction. MATERIALS AND METHODS: We retrospectively have analyzed the morbidity and mortality observed in operated patients. Risk factors for postoperative morbidity and mortality were analyzed by logistic regression model. We have compared the morbidity and mortality estimated by the SRC score with that observed using the Brier Score (BS). A BS of 0 indicated perfect prediction, whereas a BS of 1 indicated the poorest prediction. RESULTS: Sixty-nine patients aged 75 y (41-93) have been operated on emergency from November 2001 to August 2015. The tumor was localized in the sigmoid in 33 cases (48%), in the splenic flexure in nine cases (13%), and in the right colon in 17 cases (25%). The surgical procedures were as follows: right colectomy with anastomosis (29%), diverting proximal iliac colostomy (23%), and subtotal colectomy with anastomosis (19%). The SRC score indicated a good predictivity for mortality (9.8% predicted versus 8.7% observed, BS = 0.058), for morbidity (33.4% versus 40.6%, BS = 0.209), and for serious morbidity (25.5% versus 17.4%, BS = 0.131). In multivariate analysis, SRC was an independent risk factor for mortality (P = 0.030 odds ratio [OR] = 1.07 [1.01-1.15]) and morbidity (P = 0.001 OR = 1.16 [1.08-1.27]). CONCLUSIONS: SRC score is a reliable tool for assessing the morbidity and mortality of obstructive colon cancer and could help with adapting the surgical gesture to the risks predicted.

AIM: The rectosigmoid junction is the limit separating the sigmoid colon and rectum. This transition zone has different definitions. We want to highlight different landmarks of the rectosigmoid junction (RSJ), to help the clinicians to adopt a consensual definition. METHOD: We reviewed anatomical, endoscopic, physiological and surgical points of view concerning the rectosigmoid junction (RSJ). RESULTS: The rectosigmoid junction has a different definition depending on who is studying it. Nevertheless, it is a high pressure location, a place connecting different muscles organizations, neurological systems or vascular anastomosis. The clear pathophysiology of the RSJ is not yet determined with certainty, but its resection is essential for the therapeutic care of patients and also for the improvement of surgical skills. From a surgical point of view, anatomical landmarks has to be chosen: easily reproducible and identifiable. The disappearance of taenia coli (belonging to the colon) and the peritoneal reflection (recto-genital pouch), located below the upper rectum, seem the most reliable. The level of rectal section must, in any case, be below the promontory. CONCLUSION: There is not a single definition, but rather several definitions of the RSJ. Each one of them reflects one appearance of this region: embryological and anatomical evolution or clinical entity. From a surgical point of view, the criterion which seems to be the most reliable is the disappearance of taenia coli and the peritoneal reflection (recto-genital pouch).

Colorectal cancer risk factors increase with age, comorbidities, delayed diagnosis, obstruction, emergency and frailty. Surgery is the standard treatment as the survival rate for this pathology is the same as in young patients. It would appear that there is an excess morbidity and mortality of colorectal cancer surgery in the elderly. Early rehabilitation is to be favoured during the postoperative period.

AIMS: To characterize the nature and function of the levator ani muscle innervation pathways and to perform a comprehensive three-dimensional reconstruction of female pelvic innervation. METHODS: A computer-assisted anatomical dissection protocol was applied to seven female human fetuses, after approval from the national biomedicine agency. Specimens were serially sectioned and immunostained for overall (antibody against protein S100), somatic (antibody against peripheral myelin protein 22), adrenergic (antibody against tyrosine hydroxylase), cholinergic (antibody against vesicular acetylcholine transferase), and nitrergic (antibody against the neural isoform of nitric oxide synthase) nerve fibers. Slides were digitized for three-dimensional reconstructions using WinSurf®. RESULTS: Three main nerve pathways to the levator ani muscle were observed: the levator ani nerve, the pudendal nerve, and the inferior hypogastric plexus. The pudendal nerve was both somatic and autonomic, located below the levator ani muscle (infralevator pathway), supplying innervation to the inferior aspect of the levator ani muscle. The levator ani nerve was solely somatic, located above the levator ani muscle (supralevator pathway), supplying innervation to the superior aspect of the levator ani muscle. The inferior hypogastric plexus nerve fibers were solely autonomic, located in between the levator ani muscle and pelvic organs (endolevator pathway), supplying innervation to the medial portion of the levator ani muscle. CONCLUSIONS: Our study provides a new representation of levator ani muscle innervation with three nerve pathways, and the levator ani muscle itself as an anatomical landmark.

INTRODUCTION: In the pelvis, the rectogenital septum (RGS) separates the urogenital compartment from the digestive compartment. In men, it corresponds to Denonvilliers' rectoprostatic fascia or rectovesical septum (RVS). Its purpose-and, indeed, its existence-are controversial in women. The purpose of this review was to update knowledge about the RGS in women and, in particular, to clarify its relationship to pelvic nerves in order to deduce practical consequences of pelvic surgery and compare it to the RVS in men. METHODS: A review of the anatomical and surgical literature was undertaken. Evidence for embryological origin, composition, and surgical importance of the RGS in women and men is suggested. RESULTS: This manuscript presents evidence of the existence of the RGS in both women (rectovaginal septum, RVaS) and men (rectovesical septum, RVS). It originates from the genital structures and extends from the rectogenital pouch to the perineal body. It is composed of connective tissue associated with bundles of smooth muscle cells and has lateral expansions in close contact with neurovascular bundles originating from the inferior hypogastric plexus. During pelvic surgery for carcinoma, preservation of nerve fibers of erectile bodies is necessary if possible. The RGS is thus an important surgical landmark during urogenital sinus surgery, prolapse surgery, and proctectomy in women as well as during proctectomy and prostatectomy in men. CONCLUSIONS: The RGS is present in women as well as in men, with great similarities between the two sexes. It represents an important surgical landmark during pelvic nerve-sparing surgery.

BACKGROUND: Roux-en-Y gastric bypass (RYGBP) is a validated technique for the treatment of morbid obesity and results in a significant rate of remission of type 2 diabetes (T2D). Omega gastric bypass (OGBP) is an effective and simpler alternative for weight loss, but its effect on T2D is unclear. METHODS: Between December 2006 and September 2012, 804 laparoscopic OGBPs were carried out in our centre. Among these, 100 (12.4%) patients had T2D at the time of the intervention. Remission of T2D was defined by a glycated haemoglobin (HbA1c) level of <6% without concomitant treatment. RESULTS: Postoperative follow-up was completed by 81 patients (mean age: 49 ± 11 years; mean weight at surgery: 133 ± 29 kg; mean body mass index (BMI): 47 ± 9 kg/m(2)). Mean preoperative HbA1c was 8 ± 2 g/dL. Before OGBP, seven patients (9%) had received no oral hypoglycaemic treatment, 30 (37%) had received monotherapy, 26 (32%) bitherapy, six (7%) tritherapy and 12 (15%) patients had used insulin. Over a mean follow-up of 26 months (range 1-75), mean weight decreased to 94 ± 23 kg and mean BMI to 35 kg/m(2). Seventy-one (88%) patients had complete remission of T2D and the other 10 (12%) had reduced their treatment. Seven patients (58%) initially treated with insulin no longer required this treatment. Mean time to remission of T2D for patients receiving one or more oral therapies versus insulin was 6.9 versus 17.9 months. CONCLUSIONS: OMBP is effective treatment for obesity in terms of weight loss and remission of T2D.

BACKGROUND AND AIMS: Gastric per-oral endoscopic myotomy (G-POEM) is a new therapeutic option for the treatment of refractory gastroparesis. However, the outcome of G-POEM after the failure of gastric electrical stimulation (GES) or other pylorus-targeting therapies has been poorly reported. METHODS: Data were collected from patients referred for G-POEM for refractory gastroparesis. The efficacy in patients with previous interventional techniques was compared to patients naïve to instrumental technique. The primary endpoint was the 6-month clinical success rate, defined as at least a 1-point decrease in the Gastroparesis Cardinal Symptom Index (GCSI). RESULTS: Among 48 patients referred for G-POEM, 32 patients had previous instrumental treatments (66%): 15 (31%) had GES, and 17 (35%) had pyloric endoscopic dilation or toxin injection. The technical success rate was 100%. At 6 months, clinical success was achieved in 25/48 patients (52%) and the GCSI decreased from 3.38 (2.94-3.95) to 2.25 (1.11-3.36) (p < 0.001). The 6-month success rate was similar in patients with or without previous instrumental treatment (50.0% vs 56.3%; p = 0.41). The complication rate was also similar in the two groups (6.3% vs 12.5%; p = 0.59), with only one severe adverse event. The only predictive factor for success at 6 months was a higher body mass index (OR = 1.14 [1.01-1.32]; p = 0.05). CONCLUSION: G-POEM is safe and remains effective after GES or previous pyloric treatment failure, with 50% efficacy at 6 months. The therapeutic strategy in refractory gastroparesis remains to be defined.
RESUMEN
BACKGROUND: The main concerns following sleeve gastrectomy (SG) include the risk of gastroesophageal reflux disease (GERD) and its complications, such as Barrett's esophagus (BE). However, there is conflicting data on esophageal conditions, and studies on alterations of gastric mucosa after SG are lacking, despite reported cases of gastric cancer. Our aim was to assess esophageal and gastric lesions after SG. METHODS: From November 2017, an upper gastrointestinal endoscopy (UGE) was proposed at least 3 years after SG to all patients operated on in our institution. Endoscopic results and gastric histological findings were analyzed. BE was defined as endoscopically suspected esophageal metaplasia with histological intestinal metaplasia. RESULTS: Between September 2008 and August 2018, 375 patients underwent SG at our institution, of which 162 (43%) underwent at least one UGE 3 years or more after SG (91% women, mean preoperative age: 43.3±10.3 years). Despite a significant increase in the prevalence of symptomatic GERD, hiatal hernia, and esophagitis after SG (p<0.001 vs. preoperatively), no cases of BE were detected. Gastric dysplasia was not found and the prevalence of gastric atrophy tended to decrease after SG. However, 27% of patients with gastric biopsies developed antral reactive gastropathy. CONCLUSIONS: At a mean follow-up of 54 months after SG, no BE or gastric dysplasia was identified. However, reactive gastric lesions appeared, and their long-term consequences need to be further clarified. Thus, the timing of endoscopic follow-up, starting as early as 3 years after SG should be reevaluated to improve patient adherence with long-term endoscopies.
