BACKGROUND: Due to the SARS-COV2 pandemic-related restrictions the 2020 Belgian Surgical Week (BSW) was organized as a virtual congress, being the first surgical, virtual congress in Belgium. Since this was a new experience and probably not the last, we aim to share our experience to assist other professionals in organizing their virtual events. METHODS: The 'BSW-light' was organized by the RBSS in collaboration with a Professional Congress Organizer (PCO), which is described in detail. Analytical data of the event were provided by the PCO and a UEMS 'live educational events participant evaluation form' based survey was sent out to all registered participants, using google forms, to evaluate the event. RESULTS: During 2 days, 78 prerecorded presentations were broadcasted in 2 virtual conference rooms, each followed by a live Q & A session. The plenary session on the third day contained 8 live presentations, both from Belgium and from abroad. A total of 503 people registered for the congress, of whom 224 trainees. Each session attracted 158 visitors on average, each spending an average of 73 min. Attendees were satisfied with the technical aspect of the virtual congress, but they preferred an event that is at least partially live. CONCLUSION: Although the 'BSW-light' proved to be successful, a preference to meet in real life remained. However, given its potential, we should keep an open mind towards integrating the advantages of a virtual meeting into a live event. ispartof: ACTA CHIRURGICA BELGICA vol:123 issue:2 pages:105-109 ispartof: location:England status: published

The CADISS® system combines the use of a topical formulation of mesna (sodium 2-Mercaptoethane sulfonate) to facilitate selective dissection of pathological and fibrotic tissues with a non-cutting instrument for a safer dissection. A prospective, multi-site, clinical trial was performed to explore the use of the CADISS® system in laparoscopic cholecystectomy for acute cholecystitis.A total of 15 patients were enrolled at different severity stages of pathology according to Tokyo classification. They were operated on prior to, or after 72 h of, the onset of symptoms. The primary measure was the number of critical dissection steps successfully achieved using the CADISS® system without cutting instruments.Five patients were operated on before 72 h of symptom onset and ten after. All the dissections were successfully achieved using the CADISS® method. No mortality was recorded. No conversion to open surgery was performed. No bile duct injury was observed. Other endpoints (facilitation of dissection of critical structures, identification of cleavage planes and reduction of risk) had scores of above nine on our Likert scale. Four postoperative serious adverse events including cholangitis, fever, pulmonary embolism and right hepatic artery pseudoaneurysm were reported. However, they seemed to be more related to cholecystitis or local conditions rather than the use of the CADISS® method.This is the first study to investigate the use of the CADISS® System in cholecystectomy. The CADISS® system seemed to facilitate dissection in acute cholecystitis. Encouraging results are reported independently of the severity grade of cholecystitis and the delay in performing the surgery. Even now, laparoscopic cholecystectomy for acute cholecystitis remains a surgical challenge. Techniques that could facilitate this operation and reduce surgical complications may be helpful. Further studies should be conducted to confirm our preliminary results. Trial registration Clinical trials.gov NCT05041686.

Objective: Fistulotomy remains the gold standard for the surgical treatment of simple anal fistula, but may cause fecal incontinence and a characteristic anal 'keyhole' deformity. Although seemingly trivial, keyhole deformity may lead to bothersome symptoms such as anal pruritus and fecal soiling. This study aims to evaluate the efficacy of fistulectomy and primary sphincteroplasty (FIPS), a technique with immediate sphincter reconstruction, in the treatment of simple anal fistula and the prevention of keyhole deformity created by simple fistulotomy.Methods: A retrospective study was performed on all consecutive patients who underwent FIPS for a simple anal fistula at our institution between January 2015 and August 2019. The primary outcome of the study was the rate of early postoperative wound dehiscence, which essentially transforms a FIPS into a simple fistulotomy and may lead to keyhole deformity. All patients received follow-up at regular intervals to evaluate fistula healing and the presence of keyhole deformity.Results: FIPS was performed in 24 patients (median age: 52.8 years). After a median follow-up time of 3.0 (2.0, 6.3) months, the overall healing rate was 95.8% (23/24 patients). Six (25%) patients experienced early postoperative wound dehiscence resulting in the development of a keyhole deformity. Five of them were symptomatic (mainly soiling). Keyhole deformity was diagnosed at a median time of 6.0 (3.8, 7.5) months postoperatively. The occurrence of early wound dehiscence and subsequent keyhole deformity was associated with a posteriorly located fistula (p = .02).Conclusion: FIPS avoids the development of keyhole deformity in the majority of patients with simple anal fistula, but is less successful in posterior fistulas. Since FIPS is a very effective, fast and simple procedure, it should be considered a valid alternative for the treatment of every simple anal fistula.

Background: Belgium was one of the first European countries affected by the first wave of the Covid-19 epidemic after Italy and France and has the highest rate of Covid-19-related deaths. Very few studies have evaluated the impact of the pandemic on surgical activity on a large scale. The primary objective of this national survey was to evaluate the impact of the first wave of the Covid-19 pandemic on surgical activities (elective non-oncological and oncological) in Belgian hospitals. Methods: A nationwide, multicenter survey was conducted in Belgium by the Royal Belgian Surgical Society (RBSS) board. The questionnaire focused on digestive surgical activity at different time points: period 1 (P1), before the epidemic; period 2 (P2), lockdown; and period 3 (P3), after stabilization of the epidemic. Results: The participation rate in the survey was 28.2% (24 out of 85 solicited hospitals), including 15 (62.5%) from the French speaking part of Belgium and 9 (37.5%) from the Flemish speaking part. Eighteen (75%) were non-academic and 6 (25%) were academic hospitals. All surgical activities were impacted by the Covid-19 pandemic except for the number of cholecystectomies. No statistical differences were observed between regions or according to the type of hospital. Conclusions: Our national survey confirms that the COVID-19 outbreak has severely impacted in-person consultations and surgical activity for benign and malignant disease and for acute appendicitis. However, procedures for benign disease were much more affected than those for malignancies., SCOPUS: ar.j, info:eu-repo/semantics/published

Midgut volvulus is a rare cause of acute abdomen characterized by a twisting of the entire small intestine around its mesenteric pedicle. It is a well-known complication of intestinal malrotation usually occurring in infants and young children. We report a rare case of a midgut volvulus without any underlying condition occurring in a young adult.A 24-year-old male was admitted to our surgical department with symptoms and signs of small bowel obstruction. The abdominal computed tomography (CT) scan showed dilatation of the entire small intestine and a rotation of the mesentery. The patient underwent an urgent explorative laparoscopy with conversion to median laparotomy, revealing a midgut volvulus with marked intestinal ischemia. Mesenteric fixation was normal but the mesenteric pedicle was described as relatively narrow. The midgut volvulus was untwisted with subsequent recovery of the intestinal ischemia.The postoperative period was marked by prolonged ileus requiring nasogastric tube decompression that gradually resolved after 1 week. The patient was discharged on the tenth postoperative day. He had fully resumed his daily activities 1 month after surgery and had experienced no recurrent symptoms 6 months later.Primary midgut volvulus is an extremely rare condition that must be considered in all young adults presenting with intestinal obstruction without previous abdominal surgery. Early diagnosis and immediate surgical intervention are the key factors to a successful outcome.

Purpose Laparoscopic primary or incisional abdominal hernia repair with intraperitoneal mesh placement is a well-accepted and safe technique. Evidence for complications however remains inconclusive, and little is known about the occurrence of postoperative ileus secondary to postoperative intra-abdominal adhesions with different types of IPOM meshes used. Therefore, we retrospectively compared the occurrence of postoperative ileus between two of the different meshes used in our center. Methods Three hundred seventy-five patients who underwent ventral hernia repair with intraperitoneal mesh placement, either with a DynaMesh (R)-IPOM (FEG Textiltechnik mbH, Aachen, Nordrhein-Westfalen, Germany) or a Parietex (TM) Composite mesh (Medtronic, Minneapolis, MN, USA), at the Heilig-Hart Hospital in Lier (Antwerp, Belgium) between 2012 and 2017 were retrospectively compared with regard to the occurrence of postoperative ileus until 6 weeks postoperatively. Baseline demographics and clinical data up to 6 weeks postoperatively of the patients in the two mesh groups are provided. Results The DynaMesh (R)-IPOM mesh group was associated with a significantly higher incidence of postoperative ileus compared with the Parietex (TM) Composite mesh group with a cutoff limit at postoperative day 1 (n = 17, 6.8% vs. n = 0, 0.0%; P = 0.003) and postoperative day 4 (n = 13, 5.2% vs. n = 0, 0.0%, P = 0.006), even with a mesh surface area of

Non-occlusive mesenteric ischemia (NOMI) is an infrequent cause of acute mesenteric ischemia with atypical symptoms and a high mortality.We report two cases of NOMI characterized by their difference in etiology, treatment and outcome.In the first case, the patient developed NOMI after septic shock, she was successfully treated with surgery. The second patient experienced two episodes of cardiac arrest followed by NOMI. He received only supportive care and died shortly after. We present a short review of the literature, discussing epidemiology, pathophysiology, clinical presentations, diagnosis and management of NOMI.NOMI is a rare disease with a difficult diagnosis. Early recognition and treatment with supportive therapy, vasodilator drugs and possibly surgery can significantly lower mortality.

We present the case of a 58-year-old man who underwent urgent blowhole colostomy for toxic megacolon (TM) secondary toClostridium difficileinfection (CDI). This infection occurred under antibiotic coverage with amoxicillin-clavulanic acid, four days after laparoscopic sigmoidectomy in our hospital. Although prospective clinical research regarding the surgical management of TM is lacking, decompressive procedures like blowhole colostomy are reported to carry a high risk of postoperative morbidity and mortality and are widely regarded as obsolete. Subtotal or total colectomy with end ileostomy is currently considered the procedure of choice. After presenting our case, we discuss the literature available on the subject to argue that the scarce evidence on the optimal surgical treatment for TM is primarily based on TM associated with inflammatory bowel diseases (IBD) and that there might be a rationale for considering minimally invasive procedures like blowhole colostomy for CDI-associated TM.

OBJECTIVES: The specific contribution of the herniation of an abdominal antireflux fundoplication into the chest to symptomatic and therefore surgical failure remains unclear. METHODS: The study was conducted in 189 consecutive fundoplication patients, categorized as patients reoperated on for chest herniation of either an abdominal 360° (Group 1; n = 95) or a partial (Group 2; n = 10) fundoplication, and patients having undergone an intrathoracic 360° fundoplication for short oesophagus (Group 3; n = 84; reference group). There were four subgroups in Group 1: 1A: wrap still complete and perioesophageal; 1B: wrap still complete but perigastric; 1C: wrap still perioesophageal but partially disrupted and 1D: wrap perigastric and partially disrupted. RESULTS: The prevalence of defective symptoms (heartburn and regurgitation) was significantly lower (P < 0.0001) in Group 3 (0.0%) and Subgroup 1A (3.7%) than in Subgroups 1B (84.4%), 1C (86.7%) and 1D (100%) and Group 2 (100%). The prevalence of obstructive symptoms (dysphagia, chest pain, necrosis and perforation) was significantly higher (P < 0.0001) in Subgroup 1A (100%) than in Subgroups 1B (57.8%), 1C (60.0%) and 1D (25.0%). The prevalence of a short oesophagus, an abdominal wall hernia repair and high abdominal pressure episodes in reoperated patients were 13.7, 36.2 and 67.2%, respectively. CONCLUSIONS: Unlike perigastric or partial fundoplication, a 360° perioesophageal abdominal fundoplication, when herniated into the chest, is still effective against reflux. Obstructive symptoms are due to either diaphragmatic strangulation or perigastric migration of the wrap (slipknot effect). Short oesophagus, weakness of the abdominal wall and high abdominal pressure episodes favour the herniation process.

OBJECTIVE: To assess the long-term results of the duodenal switch operation made for pathologic transpyloric duodenogastric reflux (DGR). SUMMARY BACKGROUND DATA: DGR symptoms and lesions are poorly responsive to medical treatment. METHODS: A duodenal switch operation was made on 48 patients suffering from pathologic transpyloric DGR either unrelated (n = 28) or secondary (n = 20) to previous upper gastrointestinal (GI) surgery, including cholecystectomy or vagotomy. The diagnosis was based on the combination of several objective arguments: a long history of gastric symptoms (ie, nausea, epigastric pain, and/or bilious vomiting) poorly responsive to medical treatment (48 of 48), gastroesophageal reflux symptoms unresponsive to proton-pump inhibitors (PPI) (23 of 29), gastritis on upper GI endoscopy (37 of 48) and/or at histology (28 of 41), presence of a bilious gastric lake at >1 upper GI endoscopy (30 of 48), DGR at diisopropyl iminodiacetic acid (DISIDA) scintigraphy scanning (7 of 13), pathologic 24-hour intragastric bile monitoring with the Bilitec device (40 of 41), and absence of Helicobacter pylori antral infection (39 of 41). RESULTS: At follow-up (median, 81 months), gastric symptoms were nil, had improved, and remained unchanged in 29 (60.4%), 16 (33.3%), and 2(4.2%) patients, respectively, and 1 patient experienced symptomatic recurrence after a 92-month symptom-free period (2.1%). Among the 44 patients who had postoperative upper GI endoscopy, 42 (95.5%) had no gastritis whereas 5 (11.3%) had an ulcer at the duodenojejunostomy. Gastric exposure to bile at postoperative 24-hour intragastric Bilitec test in 36 patients was nil, within the normal range, and still slightly pathologic in 15 (41.7%), 19 (52.8%), and 2 (5.5%), respectively. CONCLUSIONS: The duodenal switch operation made on patients in whom diagnosis of pathologic transpyloric DGR is supported by several objective arguments provides most of them with symptomatic and endoscopic improvement parallel to abolishment or normalization of gastric exposure to bile. Postoperative PPI therapy during a 2-month period is to be recommended to prevent the development of an anastomotic ulcer.

The Implantable Gastric Stimulator (IGS(R)), a pacemaker-like device, has been found to be safe and effective to induce and maintain weight loss. The LOSS (Laparoscopic Obesity Stimulation Survey) is a prospective non-randomized trial which enrolled 69 patients involving 11 investigator centers in 5 European Countries. In 19 patients, ghrelin was analyzed.Between January 2002 and December 2003, 69 patients (F/M 49/20), mean age 41 years (18-65) underwent IGS implantation. Mean BMI was 41 (35-57), mean weight 115.0 kg (65-160) and mean excess weight (EW) 52 kg (13-89). The IGS was actived 30 days after implantation. In a subset of 19 patients studied further, 0, 6, and 12 months appetite and satiety score were evaluated and 0 and 6 months ghrelin profile was analyzed.The mean +/- standard error %EWL was: 8.6+/-1.8 at 1 month, 15.8+/-2.3 at 3 months, 17.8+/-2.6 at 6 months, 21.0+/-3.5 at 10 months, and 21.0+/-5.0 at 15 months. There were no intraoperative surgical or long-term complications. 7 intra-operative gastric penetrations occurred, observed by gastroscopy, without sequelae. 1 patient required a reoperation to remove a retained lead needle. In the subset of 19 patients, appetite was reduced and post-prandial and inter-prandial satiety was increased after IGS implantation. In the 19 patients, despite weight reduction, ghrelin did not increase.IGS can be implanted laparoscopically with minimal perioperative complications. Appetite is reduced and satiety is increased after the implantation. Ghrelin levels could be one of the mechanisms explaining weight loss and weight maintenance in IGS patients. If weight loss is maintained, IGS could be considered a good option for selected patients.
