Diverticulitis And The Age Factor – Does Age Matter?

Acute diverticulitis has been traditionally associated with worse outcome in young patients, indicating a more aggressive surgical approach is required for them. The aim of this study was to assess whether acute diverticulitis was more virulent in young patients.

Early Experience with Laparoscopic Lavage in Acute Complicated Diverticulitis

Background: Contemporary surgical management of complicated diverticulitis is controversial. Traditionally, the gold standard has been resection and colostomy, but recently peritoneal lavage and drainage without resection in cases of purulent peritonitis have been suggested. This study aims to review our initial experience with laparoscopic peritoneal lavage for complicated diverticulitis. Methods: Retrospective review of all patients who underwent emergent peritoneal lavage and drainage for acute complicated diverticulitis. Results: Five-hundred-thirty-eight patients admitted for acute diverticulitis between 2007 and 2012 were recorded in the database. Thirty seven underwent emergent surgery of which 10 had peritoneal lavage and drainage without colonic resection for complicated diverticulitis causing peritonitis. Peritoneal lavage and drainage resulted in the resolution of acute symptoms in all cases. In long-term follow-up, 3 (30%) patients required elective resection owing to symptomatic disease, two of these due to recurrent diverticulitis, and one owing to complicated fistula following the procedure. Conclusion: Peritoneal lavage is a feasible option for complicated diverticulitis with purulent non-fecal peritonitis, but a significant portion of the patients may require elective resection. Comparative studies with emergent resection are needed to determine the role of peritoneal lavage in complicated diverticulitis.

Preoperative Nutritional Optimization for Crohn’s Disease Patients Can Improve Surgical Outcome

Background: Preoperative preparation of patients with Crohn’s disease is challenging and there are no specific guidelines regarding nutritional support. The aim of this study was to assess whether preoperative nutritional support influenced the postoperative outcome. Methods: A retrospective, cohort study including all Crohn’s disease patients who underwent abdominal surgery between 2008 and 2014 was conducted. Patients’ characteristics and clinical and surgical data were recorded and analyzed. Results: Eighty-seven patients were included in the study. Thirty-seven patients (42.5%) received preoperative nutritional support (mean albumin level 3.14 vs. 3.5 mg/dL in the non-optimized group; p < 0.02) to optimize their nutritional status prior to surgery. Preoperative albumin level, after adequate nutritional preparation, was similar between the 2 groups. The 2 groups differ neither in demographic and surgical data, overall post-op complication (p = 0.85), Clavien-Dindo score (p = 0.42), and length of stay (p = 0.1). Readmission rate was higher in the non-optimized group (p = 0.047). Conclusion: Nutritional support can minimize postoperative complications in patients with low albumin levels. Nutritional status should be optimized in order to avoid hazardous complications.

Volvulus and bowel obstruction in ATR‐X syndrome—clinical report and review of literature

Alpha thalassemia‐mental retardation, X‐linked (ATR‐X) syndrome is a rare genetic disorder with a variety of clinical manifestations. Gastrointestinal symptoms described in this syndrome include difficulties in feeding, regurgitation and vomiting which may lead to aspiration pneumonia, abdominal pain, distention, and constipation. We present a 19‐year‐old male diagnosed with ATR‐X syndrome, who suffered from recurrent colonic volvulus that ultimately led to bowel necrosis with severe septic shock requiring emergent surgical intervention. During 1 year, the patient was readmitted four times due to poor oral intake, dehydration and abdominal distention. Investigation revealed partial small bowel volvulus which resolved with non‐operative treatment. Small and large bowel volvulus are uncommon and life‐threatening gastrointestinal manifestations of ATR‐X patients, which may contribute to the common phenomenon of prolonged food refusal in these patients.

Reversal of Hartmann’s procedure: still a complicated operation

Hartmann’s procedure, colonic resection with an end colostomy and rectal closure, is used in a variety of surgical emergencies. It is a common surgical procedure that is often practiced in patients with colonic obstruction and colonic perforation, resolving the acute clinical situation in the majority of cases. Reversal of Hartmann’s procedure with restoration of bowel continuity occurs in a significantly low percentage of patients. There are several reasons contributing to the fact that many patients remain with a permanent colostomy following Hartmann’s procedure. These include factors related to the patients’ clinical status but also to the significant difficulty and morbidity related to the surgical reversal of Hartmann’s procedure. The aim of this study was to review the factors related to the fairly low percentage of patients undergoing Hartmann’s reversal as well as surgical techniques that could help surgeons restore intestinal continuity following Hartmann’s procedure and deal with the postoperative outcomes.

A Single Tertiary Center 10-Year Experience in the Surgical Management of Gastrointestinal Bezoars

BACKGROUND Gastrointestinal (GI) bezoars are the most common foreign bodies causing obstruction in the GI tract. They are frequently seen following upper GI tract surgery and surgical intervention is required often. The aim of this study is to describe the surgical management of GI bezoars. MATERIALS AND METHODS A retrospective cohort study, including all patients diagnosed with bezoars between May 2008 and May 2017, was conducted. Patient charts were reviewed, and demographics, clinical, surgical, and postoperative data were collected and analyzed. RESULTS Forty-five patients were included, with a mean age of 62.04 years (Range 18-91). Thirty patients underwent previous surgery (66.6%), most commonly surgical interventions for peptic ulcer disease (22 patients, 73.3%). Obstruction was most common in the ileum (27 patients, 60%). Thirty-nine patients (86.7%) required surgical intervention. Laparoscopy was attempted in 20 patients (51.2%), but conversion to open procedure was required in 11 patients (55%). Postoperative complication rate was 41%. No preoperative factors were found to be correlated with postoperative complications. Postoperative complications were associated with a longer length of stay (P = .006) and a higher readmission rate (P = .04). Patients treated with laparoscopy tended to have a lower BMI (P = .04), less previous surgeries (P = .04), and a bezoar located more proximally (P = .03), however, laparoscopy showed no benefit in complications rate, readmissions, and length of stay. CONCLUSIONS GI bezoars require surgical intervention at high rates. Postoperative complications are common. Completion of an upper GI endoscopy is important and should be performed at an early stage of management.
