Surgery for Crohn's disease: new developments

Surgical treatment of inflammatory bowel disease: From the gastroenterologist's stand-point

Treatment of ulcerative colitis (UC) and Crohn's disease (CD) represents, in the majority of cases, a real challenge to the gastroenterologist's abilities and skills as well as a clinical test concerning his/her levels of medical knowledge and experience. During the last two decades, our pharmaceutical arsenal was significantly strengthened, especially after the introduction of the so-called biological agents, drugs which to a large extent not only improved the results of conservative treatment but also changed the natural history of the disease. However, colectomy is still necessary for some patients with severe UC although smaller compared to the past, precisely because of the improvements achieved in the available conservative treatment. Nevertheless, surgeries to treat colon dysplasia and cancer are increasing to some extent. At the same time, satisfactory improvements in surgical techniques, the pre-and post-operative care of patients, as well as the selection of the appropriate time for performing the surgery have been noticed. Regarding patients with CD, the improvement of conservative treatment did not significantly change the need for surgical treatment since two-thirds of patients need to undergo surgery at some point in the course of their disease. On the other hand, the outcome of the operation has improved through good preoperative care as well as the wide application of more conservative surgical techniques aimed at keeping as much of the bowel in situ as possible. This article discusses the indications for surgical management of UC patients from the gastroenterologist's point of view, the results of the emerging new techniques such as transanal surgery and robotics, as well as alternative operations to the classic ileo-anal-pouch anastomosis. The author also discusses the basic principles of surgical management of patients with CD based on the results of the relevant literature. The self-evident is emphasized, that is, to achieve an excellent therapeutic result in patients with severe inflammatory bowel disease in today's era; the close cooperation of gastroenterologists with surgeons, pathologists, imaging, and nutritionists is of paramount importance.

Laparoscopy for Crohn's disease: A comprehensive exploration of minimally invasive surgical techniques

BACKGROUND

Along with the unceasing progress of medicine, Crohn's disease (CD), especially complex CD, is no longer a taboo for minimally invasive surgery. However, considering its special disease characteristics, more clinical trials are needed to confirm the safety and feasibility of laparoscopic surgery for CD.

AIM

To investigate the safety and feasibility of laparoscopic enterectomy for CD, assess the advantages of laparoscopy over laparotomy in patients with CD, and discuss comprehensive minimally invasive surgical techniques in complex CD.

METHODS

This study prospectively collected clinical data from patients with CD who underwent enterectomy from January 2017 to January 2020. It was registered in the Chinese clinical trial database with the registration number ChiCTR-INR-16009321. Patients were divided into a laparoscopy group and a traditional laparotomy group according to the surgical method. The baseline characteristics, operation time, intraoperative blood loss, temporary stoma, levels of abdominal adhesion, pathological characteristics, days to flatus and soft diet, postoperative complications, hospitalization time, readmission rate within 30 d, and hospitalization cost were compared between the two groups.

RESULTS

A total of 120 eligible patients were enrolled into the pre-standardized groups, including 100 in the laparoscopy group and 20 in the laparotomy group. Compared with the laparotomy group, the postoperative hospitalization time in the laparoscopy group was shorter (9.1 ± 3.9 d vs 11.0 ± 1.6 d, P < 0.05), the days to flatus were fewer (2.8 ± 0.8 d vs 3.5 ± 0.7 d, P < 0.05), the days to soft diet were fewer (4.2 ± 2.4 d vs 6.2 ± 2.0 d, P < 0.05) and the intraoperative blood loss was less (103.3 ± 80.42 mL vs 169.5 ± 100.42 mL, P < 0.05). There were no statistically significant differences between the two groups in preoperative clinical data, operation time (149.0 ± 43.8 min vs 159.2 ± 40.0 min), stoma rate, levels of abdominal adhesion, total cost of hospitalization, incidence of postoperative complications [8.0% (8/100) vs 15.0% (3/20)], or readmission rate within 30 days [1.0% (1/100) vs 0.00 (0/20)].

CONCLUSION

Compared with laparotomy, laparoscopic enterectomy promotes the recovery of gastrointestinal function, shortens the postoperative hospitalization time, and does not increase the incidence of postoperative complications. Laparoscopic enterectomy combined with varieties of minimally invasive surgical techniques is a safe and acceptable therapeutic method for CD patients with enteric fistulas.

Primary Humoral Immune Deficiencies: Overlooked Mimickers of Chronic Immune-Mediated Gastrointestinal Diseases in Adults

In recent years, the incidence of immune-mediated gastrointestinal disorders, including celiac disease (CeD) and inflammatory bowel disease (IBD), is increasingly growing worldwide. This generates a need to elucidate the conditions that may compromise the diagnosis and treatment of such gastrointestinal disorders. It is well established that primary immunodeficiencies (PIDs) exhibit gastrointestinal manifestations and mimic other diseases, including CeD and IBD. PIDs are often considered pediatric ailments, whereas between 25 and 45% of PIDs are diagnosed in adults. The most common PIDs in adults are the selective immunoglobulin A deficiency (SIgAD) and the common variable immunodeficiency (CVID). A trend to autoimmunity occurs, while gastrointestinal disorders are common in both diseases. Besides, the occurrence of CeD and IBD in SIgAD/CVID patients is significantly higher than in the general population. However, some differences concerning diagnostics and management between enteropathy/colitis in PIDs, as compared to idiopathic forms of CeD/IBD, have been described. There is an ongoing discussion whether CeD and IBD in CVID patients should be considered a true CeD and IBD or just CeD-like and IBD-like diseases. This review addresses the current state of the art of the most common primary immunodeficiencies in adults and co-occurring CeD and IBD.

The Association of Coloproctology of Great Britain and Ireland consensus guidelines in surgery for inflammatory bowel disease

AIM

There is a requirement of an expansive and up to date review of surgical management of inflammatory bowel disease (IBD) that can dovetail with the medical guidelines produced by the British Society of Gastroenterology.

METHODS

Surgeons who are members of the ACPGBI with a recognised interest in IBD were invited to contribute various sections of the guidelines. They were directed to produce a procedure based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. An editorial board was convened to ensure consistency of style, presentation and quality. Each author was asked to provide a set of recommendations which were evidence based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after 2 votes were included in the guidelines.

RESULTS

All aspects of surgical care for IBD have been included along with 157 recommendations for management.

CONCLUSION

These guidelines provide an up to date and evidence based summary of the current surgical knowledge in the management of IBD and will serve as a useful practical text for clinicians performing this type of surgery.

Minimally invasive surgery for inflammatory bowel disease: Review of current developments and future perspectives

Patients with inflammatory bowel disease (IBD) comprise a population of patients that have a high likelihood of both surgical treatment at a young age and repetitive operative interventions. Therefore surgical procedures need to aim at minimizing operative trauma with best postoperative recovery. Minimally invasive techniques have been one of the major advancements in surgery in the last decades and are nowadays almost routinely performed in colorectal resections irrespective of underlying disease. However due to special disease related characteristics such as bowel stenosis, interenteric fistula, abscesses, malnutrition, repetitive surgeries, or immunosuppressive medications, patients with IBD represent a special cohort with specific needs for surgery. This review summarizes current evidence of minimally invasive surgery for patients with Crohn’s disease or ulcerative colitis and gives an outlook on the future perspective of technical advances in this highly moving field with its latest developments in single port surgery, robotics and trans-anal techniques.

Single-incision laparoscopic surgery (SILS) for children with Crohn's disease

PURPOSE

Single-incision laparoscopic surgery (SILS) has been described in adults with Crohn's disease, but its use in pediatric Crohn's patients has been limited. The purpose of this study was to review our experience with SILS in pediatric patients with Crohn's disease.

METHODS

A retrospective review was performed for patients diagnosed with Crohn's disease who underwent small bowel resection or ileocecectomy at a freestanding children's hospital from 2006 to 2014. Data collected included demographic data, interval from diagnosis to surgery, operative time, length of stay, and postoperative outcomes.

RESULTS

Analysis identified 19 patients who underwent open surgery (OS) and 41 patients who underwent SILS. One patient (2.4 %) within the SILS group required conversion to OS. Demographic characteristics were similar between the 2 cohorts. The most common indication for surgery was stricture/obstruction (SILS 70.7 % vs. OS 68.4 %, p = 0.86), and ileocecectomy was the most common primary procedure performed (SILS 90.2 % vs. OS 100 % OS). Operative times were longer for SILS (135 ± 50 vs. 105 ± 37 min, p = 0.02). However, when the last 20 SILS cases were compared to all OS cases, the difference was no longer statistically significant (SILS 123.3 ± 34.2 vs. OS 105 ± 36.5, p = 0.12). No difference was noted in postoperative length of stay (SILS 6.5 ± 2.2 days vs. OS 7.4 ± 2.2 days, p = 0.16) or overall complication rate (SILS 24.4 % vs. OS 26.3 %, p = 0.16).

CONCLUSION

SILS ileocecectomy is feasible in pediatric patients with Crohn's disease, achieving outcomes similar to OS. As experience increased, operative times also became comparable.
