Current surgical management of intestinal rotational abnormalities

Five Hundred Patients With Gut Malrotation: Thirty Years of Experience With the Introduction of a New Surgical Procedure

OBJECTIVES

Define clinical spectrum and long-term outcomes of gut malrotation. With new insights, an innovative procedure was introduced and predictive models were established.

METHODS

Over 30-years, 500 patients were managed at 2 institutions. Of these, 274 (55%) were children at time of diagnosis. At referral, 204 (41%) patients suffered midgut-loss and the remaining 296 (59%) had intact gut with a wide range of digestive symptoms. With midgut-loss, 189 (93%) patients underwent surgery with gut transplantation in 174 (92%) including 16 of 31 (16%) who had autologous gut reconstruction. Ladd's procedure was documented in 192 (38%) patients with recurrent or de novo volvulus in 41 (21%). For 80 patients with disabling gastrointestinal symptoms, gut malrotation correction (GMC) surgery "Kareem's procedure" was offered with completion of the 270° embryonic counterclockwise-rotation, reversal of vascular-inversion, and fixation of mesenteric-attachments. Concomitant colonic dysmotility was observed in 25 (31%) patients.

RESULTS

The cumulative risk of midgut-loss increased with volvulus, prematurity, gastroschisis, and intestinal atresia whereas reduced with Ladd's and increasing age. Transplant cumulative survival was 63% at 10-years and 54% at 20-years with best outcome among infants and liver-containing allografts. Autologous gut reconstruction achieved 78% and GMC had 100% 10-year survival. Ladd's was associated with 21% recurrent/de novo volvulus and worsening (P > 0.05) of the preoperative National Institute of Health patient-reported outcomes measurement information system gastrointestinal symptom scales. GMC significantly (P ≤ 0.001) improved all of the symptomatology domains with no technical complications or development of volvulus. GMC improved quality of life with restored nutritional autonomy (P < 0.0001) and daily activities (P < 0.0001).

CONCLUSIONS

Gut malrotation is a clinicopathologic syndrome affecting all ages. The introduced herein definitive correction procedure is safe, effective, and easy to perform. Accordingly, the current standard of care practice should be redefined in this orphan population.

Sonographic Detection of Congenital Intestinal Malrotation: A Case Report

Intestinal malrotation is a rare fetal anomaly resulting from the failure of midgut rotation and fixation. Sonography is typically the first modality of choice for assessing pediatric pathology due to its high sensitivity, portability, real-time imaging capability, and non-ionizing technique; however, its role in diagnosing small bowel rotational anomalies remains limited and controversial. Fluoroscopic upper gastrointestinal imaging (UGI) is the primary diagnostic examination at most institutions. However, even on UGI, imaging findings may be equivocal. In such cases, sonography may provide additional information at facilities where it is not used as a primary diagnostic tool. This case report represents the first reported case showing how patient position is important as the typical vascular sonographic features of rotation were normal in one position but abnormal in another. In addition, this case shows how congenital intestinal malrotation was decisively diagnosed using sonographic imaging.

Situs Ambiguous Anomaly during Laparoscopic Cholecystectomy in an Adult Female

Situs anomalies are rare structural defects affecting 0.01% of general population. They present with multisystem structural defects mostly involving cardiovascular, respiratory and GI systems. Situs abnormality with presence of multiple spleen is termed as left atrial isomerism with anatomical and structural differences to its countertype situs ambiguous with asplenia (right atrial isomerism). In this case report, we present an adult case of situs ambiguous anomaly which was diagnosed incidentally during laparoscopic cholecystectomy. The patient had enlarged left lobe of liver, multiple splenules on right side, malrotated small and large gut, interrupted inferior vena cava with azygos continuation, and bilateral bilobed lungs. It is concluded that variations in situs ambiguous cases differ and a single description is not possible. It is crucial to reveal these variations by using imaging modalities and being aware of them prior to surgery and invasive intervention to prevents the possible risks and complications.

Laparoscopic Ladd Procedure for the Management of Malrotation and Volvulus

Introduction: While laparoscopic Ladd procedure is commonly performed in patients with asymptomatic malrotation, a paucity of data exists on children with volvulus or with low weight (≤3 kg). Our purpose was to evaluate the safety and efficacy of the laparoscopic Ladd procedure in these complex patient populations. Methods: A retrospective review of patients undergoing operation for malrotation from 2008 to 2018 was performed. Specific subgroup analysis was performed comparing outcomes after open and laparoscopic approaches in patients presenting with acute volvulus or in low-weight (<3 kg) patients. Results: Out of 110 patients, 38 (35%) presented with volvulus and 72 (65%) without volvulus. In patients with volvulus, 16 (42%) underwent laparoscopy and 22 (58%) had an open procedure. More patients in the open group had a preoperative diagnosis of volvulus (63.6% vs. 12.5%, P = .002). Operative time was longer in the laparoscopic group (87 vs. 61 minutes, P = .029), with 7 patients being converted to an open procedure (44%). Days to regular diet, hospital length of stay, and recurrent volvulus were similar between groups. In patients weighting <3 kg, 10 patients underwent laparoscopy and 10 patients had an open procedure. Demographics, operative time, postoperative outcomes, and complications were similar between groups. One person in the laparoscopic group was converted to open. Conclusion: Laparoscopic management of malrotation, even in the presence of volvulus and low patient weight, is safe and effective, with low rates of recurrent volvulus. If exposure is suboptimal, conversion to open in patients with volvulus should be considered.

Uncommon intestinal malrotation in adult patients: Presentation of 4 cases

Rotation anomalies are usually anomalies seen in children. It is a rare condition in adults. In this article, 4 cases are presented. In the first case, reverse rotation anomaly and appendicitis perforation were detected in a patient who had laparotomy at the age of 22 with acute abdomen. It is a unique condition that the patient had a history of previous appendectomy. Ladd band may be the cause of acute abdomen due to ileus. The patient in our second case presented a concurrent biliary stone and malrotation with Ladd band. In addition, two elderly patients who underwent hemicolectomy due to intestinal ileus caused by malrotation were presented with literature review.

Orbit technique in malrotation with non-obstructive volvulus: A novel technique of devolvulation

INTRODUCTION

Volvulus may be noted in up to two-thirds of cases involving malrotation beyond infancy. Laparoscopic devolvulation has been described as a frustrating procedure because of restricted visualization. Here, a setup and technique that address these concerns are proposed.

MATERIALS AND SURGICAL TECHNIQUE

Three boys (median age: 7 years) who had been diagnosed preoperatively with malrotation underwent laparoscopic exploration and devolvulation for volvulus found intraoperatively. The children were placed in a dorsal supine modified lithotomy position. Four 5-mm ports were inserted-one umbilically, one in the suprapubic region, and one in both the right and left iliac. After the volvulus was inspected, the right iliac atraumatic grasper was placed at the root of the mesentery. The bowel was devolvulated counterclockwise with the grasper used as a pivot-that is, the orbit technique. Once derotated, the rest of the operation proceeded with the division of Ladd's bands, the widening of the mesentery, and appendectomy.

DISCUSSION

Devolvulation was successful in all three boys. The orbit technique is a useful devolvulation technique in non-obstructive volvulus when other techniques fail.

Pediatric Abdominal Pain: An Emergency Medicine Perspective

Abdominal pain is a common complaint that leads to pediatric patients seeking emergency care. The emergency care provider has the arduous task of determining which child likely has a benign cause and not missing the devastating condition that needs emergent attention. This article reviews common benign causes of abdominal pain as well as some of the cannot-miss emergent causes.

Intestinal Rotation Anomalies

Intestinal rotation abnormality (IRA) predisposes to lethal midgut volvulus. An understanding of intestinal development illustrates the process of normal intestinal rotation and fixation. An appreciation of the clinical presentation and consequences of missed IRA will enhance clinical suspicion and timely evaluation. Selecting the appropriate imaging modality to diagnose IRA requires an understanding of the benefits and limitations of each. The Ladd's procedure continues to be the appropriate surgical treatment for IRA with or without volvulus. Laparoscopy has emerged as an option for the diagnosis and treatment of IRA. Populations in which IRA is always associated, but a Ladd's procedure rarely required, include patients with congenital diaphragmatic hernia and abdominal wall defects. Prevalence of IRA is higher in children with congenital heart disease and heterotaxy syndrome; asymptomatic patients require multidisciplinary consideration of the risks and benefits of screening for IRA, whether a Ladd's procedure is required, and the timing thereof.
