Postoperative constipation occurs relatively frequently, and can involve drug-related, surgical and lifestyle and dietary factors. Gastrointestinal motility can be altered by inflammation, surgery, opioid medications, hypnotics, anti-secretory or anesthetic drugs or by functional modifications for which the physiopathology is not well defined. There are a number of laxatives available. These include bulk laxatives, osmotic laxatives and locally acting laxatives such as suppositories and enemas. Stimulant laxatives have a role to play in the short-term management of persistent constipation. 5-HT4 receptor antagonists are recommended in refractory constipation. Other specific therapeutic laxatives can be proposed such as methylnaltrexone in opioid-induced constipation or neostigmine in Ogilvie's syndrome. The prevention and/or early detection of iatrogenic constipation, whether postoperative or not, is essential and the knowledge how to improve patient comfort and reduce the duration of gastrointestinal motor disorders with specific drugs or other means is essential, particularly the postoperative period.

Preventable diagnostic errors of lower gastrointestinal perforation: a secondary analysis of a large-scale multicenter retrospective study.
Int J Emerg Med

Department of Diagnostic and Generalist Medicine, Dokkyo Medical University Hospital, Mibu, Tochigi, Japan.
Background: Lower gastrointestinal perforation (LGP) is an acute abdominal condition associated with a high mortality rate. Timely and accurate diagnosis is crucial. Nevertheless, a diagnostic delay has been estimated to occur in approximately one-third of the cases, and the factors contributing to this delay are yet to be clearly understood.

Open ventral hernia repair is one of the most commonly performed surgeries by general surgeons worldwide. In the case of complex incisional hernias, there are adjunct techniques that can help abdominal wall reconstruction surgery, such as type A botulinum toxin (BTA), whose injection results in muscle relaxation and growth of muscle fiber length, allowing fascial closure without the need for advanced techniques. We report a case of a male patient who underwent ultrasound-guided BTA injection in the abdominal wall and, five days later, was admitted to our emergency department with dysarthria, muscular weakness, dyspnea on small exertion, and constipation.

Background: Gastrojejunostomy junction perforation is a rare yet critical complication associated with enteral tube placement, presenting unique challenges in patients with a history of Roux-en-Y gastric bypass surgery.
Case Presentation: A 63-year-old white female with a complex medical history, including heart failure, atrial fibrillation, stage 4 chronic kidney disease, and prior Roux-en-Y gastric bypass surgery in 2015, experienced a significant decline in her health. She was discharged to a skilled nursing facility after a fall but deteriorated rapidly in the 2 weeks before admission.
Paneth-like cells disruption and intestinal dysbiosis in the development of enterocolitis in an iatrogenic rectosigmoid hypoganglionosis rat model.

Department of Pharmacology and Therapeutics, Faculty of Medicine, Universitas Indonesia, Jakarta, Indonesia.
Background: Hypoganglionosis resembles Hirschsprung disease (HSCR) which is characterized by severe constipation. Enterocolitis due to hypoganglionosis or Hirschsprung-associated enterocolitis (HAEC) is a life-threatening complication of both diseases. This study investigated the role of Paneth-like cells (PLCs) and gut microbiota in the development of enterocolitis in an iatrogenic rectosigmoid hypoganglionosis rat model.
