Surgical management of intestinal malrotation in adults

Intestinal malrotation in the adult population: Diagnosis, management, and outcomes after laparoscopic Ladd procedure

BACKGROUND

The Ladd procedure is the treatment of choice for patients with intestinal malrotation; however, the long-term outcomes of the laparoscopic Ladd procedure are not well documented. This study aimed to review the presentation, management, and outcomes of adult patients who underwent a laparoscopic Ladd procedure.

METHODS

A retrospective review was conducted to identify adult patients with malrotation who underwent a laparoscopic Ladd procedure between January 1995 and June 2022 at the Mayo Clinic in Rochester, Minnesota. Patient details and follow-up data were obtained from the electronic medical records. Patients were invited to participate in a structured phone interview to assess symptoms and quality of life (QoL).

RESULTS

A total of 44 patients underwent the laparoscopic Ladd procedure. Of the 44 patients, 42 (95.5 %) were symptomatic, with 7 (16.7 %) presenting with acute symptoms. Moreover, 8 laparoscopic procedures (13.6 %) required conversion to an open procedure. The median estimated blood loss was 20 mL (IQR, 10-50), operative time was 2.3 h (IQR, 1.8-2.8), and hospital length of stay was 2 days (IQR, 2-3). Postoperative ileus was the most common complication (18.0 %). The median follow-up was 8.00 years (IQR, 2.25-13.00), with more than 90.0 % of patients having partial or complete symptom resolution. Of note, 28 patients (63.6 %) completed phone interviews. Moreover, 1 patient (2.0 %) reported a postoperative volvulus. When asked to compare their current symptoms with those preoperatively, 78.6 % of patients noted that they were significantly better. Furthermore, 85.7 % of patients reported that their QoL was significantly better after surgery. Finally, 96.4 % of patients would recommend the procedure to a friend or family member with the same condition.

CONCLUSION

The laparoscopic Ladd procedure is a safe and effective surgical procedure for adult patients with intestinal malrotation.

Identification and treatment of intestinal malrotation with midgut volvulus in childhood: a multicenter retrospective study

BACKGROUND

Intestinal malrotation is a rare condition, and its delayed diagnosis can lead to fatal consequences. This study aimed to investigate the identification and treatment of malrotation in children.

METHODS

Clinical data, imaging, operative findings, and early postoperative outcomes of 75 children with malrotation were retrospectively analyzed.

RESULTS

The mean age was 6.18 ± 4.93 days and 51.26 ± 70.13 months in the neonatal group (56 patients) and non-neonatal group (19 patients), respectively. Sixty-seven patients were under the age of 1 year at the time of diagnosis. The occurrence of bilious vomiting and jaundice was significantly higher in the neonatal group (89.29%) than that in the non-neonatal group (37.5%), p < 0.05 and p < 0.01, respectively. The incidence of abnormal ultrasound (US) findings was 97.30% and 100%, respectively, and the sensitivities of the upper gastrointestinal series were 84.21% and 87.5%, respectively. Sixty-six (88%) patients had midgut volvulus, including in utero volvulus (two patients) and irreversible intestinal ischemia (four patients). Most neonates (89.29%) underwent open Ladd's procedure with a shorter operative time (p < 0.01). Reoperation was performed for postoperative complications (four patients) or missed comorbidities (two patients).

CONCLUSIONS

Non-bilious vomiting was the initial symptom in >10% of neonates and nearly 40% of non-neonates. This highlights the importance for emergency physicians and surgeons to be cautious about ruling out malrotation in patients with non-bilious vomiting. Utilizing US can obviate the need for contrast examinations owing to its higher diagnostic accuracy and rapid diagnosis and can be recommended as a first-line imaging technique. Additionally, open surgery is still an option for neonatal patients.

Intestinal malrotation complicated with gastric cancer: A case report

BACKGROUND

Intestinal malrotation is a congenital defect of embryonic development caused by various teratogenic factors. In this condition, the intestinal tube, along with the superior mesenteric artery serving as the axis for the counterclockwise movement, is incomplete or abnormally rotated due to incomplete attachment of the mesentery and abnormal intestinal tube position. Such a case is usually asymptomatic and thus difficult to detect. Therefore, similar variant malformations are only found during an operation required for other abdominal diseases.

CASE SUMMARY

An elderly male patient was admitted to the hospital due to gastric cancer. An abdominal computed tomography (CT) scan with contrast revealed that the ascending and descending colon were parallel on the right side of the abdominal cavity, while the sigmoid colon extended into the right iliac fossa, allowing the diagnosis of congenital midgut malrotation. Following thorough preoperative preparation, the patient underwent laparoscopic radical gastrectomy to treat his gastric cancer. Intraoperatively, an exploration of the abdominal cavity uncovered the absence of the transverse colon. The distal colon at the hepatic flexure, along with the ascending colon, extended into the right iliac fossa, where it continued as the sigmoid colon. As planned, the laparoscopic radical gastrectomy was performed, and the patient was discharged from the hospital 7 d after the surgery.

CONCLUSION

Asymptomatic intestinal malrotation is best detected by CT, requiring no treatment but possibly interfering with the treatment of other diseases.

A Rare Case of Congenital Intestinal Malrotation Presented as an Intestinal Obstruction in an Adult

Malrotation of the midgut is generally considered a pediatric pathology. Adults are not usually diagnosed early, which occasionally causes delays in both diagnosis and treatment. Therefore, while dealing with patients of any chronological age with abdominal complaints, a strong index of suspicion is necessary. A midgut developmental defect known as intestinal malrotation occurs when the intestines fail to fix in the peritoneal cavity and rotate normally around the superior mesenteric artery during fetal development. Usually, it's rare to have malrotation in adults. When they are symptomatic, operational procedures are typically necessary. Even if the patient is asymptomatic, a Ladd's treatment is indicated if real malrotation is detected or discovered accidentally. In adults, intestinal malrotation rarely shows symptoms and is typically accidentally discovered. We present a unique case of a 24-year-old male who had acute abdominal pain, confirming midgut rotation with the presence of characteristic Ladd's bands on a preoperative computed tomography scan. No signs of intestinal volvulus were present. The patient had an exploratory laparotomy. This case emphasizes the rarity of intestinal malrotation and the debates about how to treat it in the adult population. It also highlights how crucial it is to properly monitor patients who present with ill-defined abdominal pain and maintain a high index of suspicion.

Malrotation in Adult and Adolescent Patients

BACKGROUND

Malrotation in children presents with bilious emesis and can be life threatening. Data on adults is lacking.

METHODS

Single institution, retrospective 20-year data collection on adult (>18 years) and adolescent patients (12-18) with symptomatic malrotation. We evaluated demographics, surgical approach, hospital stay, time to feed, and type of surgeon with descriptive statistics to analyze each group.

RESULTS

Adult (n=17) and adolescent patients (n=8) primarily presented with acute abdominal pain (82% adult, 100% adolescent), and non-bilious emesis (0%), and had elective repair. CT scan was diagnostic for 82% adults and 71% adolescents. Overall, 88% had improvement in symptoms.

CONCLUSION

In this single institution series comparing adults and adolescent patients with malrotation, 88% have resolution of pain after repair, despite atypical presentations. CT scan is diagnostic and laparoscopic approach should be considered.

A rare case of Ladd's band causing duodenal occlusion in an adult with intestinal malrotation

A congenital defect of the fetal intestinal rotation, known as malrotation of the gut, is most often identified as an acute intestinal occlusion in early infancy. Adults with this disease tend to be asymptomatic and extremely rare. We present a case of a 47-year-old woman with duodenal obstruction due to Ladd's band admitted with acute abdominal pain and vomiting.

Adult Midgut Malrotation With Chronic Volvulus With Superior Mesenteric Artery (SMA) Thrombosis: A Recherche

Intestinal malrotation is primarily a surgical condition of neonates due to abnormal intestinal rotation during fetal development. Usually, the presentation is immediately after birth. Adult midgut malrotation is rare and primarily detected at laparotomy or incidental radiological imaging for various conditions. We report a sporadic case of a 35-year-old male who presented to the surgical outpatient department (OPD) complaining of dull aching abdominal pain after taking meals for two months. He was able to tolerate a liquid diet only and able to carry out his routine work comfortably. In imaging studies, it was found to be a case of midgut malrotation with volvulus and superior mesenteric artery (SMA) thrombosis with collaterals without features of intestinal obstruction. The patient underwent diagnostic laparoscopy, and a midgut volvulus was identified with Ladd's bands. He underwent exploratory laparotomy with Ladd's procedure. Postoperatively symptoms were resolved, and the patient was discharged in stable condition. If intestinal malrotation presents in adults, it is challenging to diagnose it as it presents with atypical symptoms like chronic vague abdominal pain and weight loss. Often radiological correlation is essential to diagnose such patients. For surgical intervention, a laparoscopic approach is considered better in expert hands. Even though the disease has a chronic course, a high index of suspicion should arise when treating such cases of intestinal malrotation in an adult male. Timely surgery can do miracles and prevent catastrophic complications.

Incidental Discovery of Nonrotation in a Patient With Nonspecific Abdominal Pain: A Surgical Diagnostic Dilemma

Intestinal nonrotation is a subtype of malrotation occurring when the midgut fails to rotate before returning to the peritoneal cavity between weeks 8-10 of development. Though sometimes presenting as volvulus during the neonatal period, a subset of patients remains asymptomatic and are identified incidentally as adults. When patients with intestinal nonrotation present with abdominal symptoms, there exists a diagnostic dilemma for the treating surgeon. We present the case of a patient who presented with acute abdominal pain and vomiting, with radiographic findings of intestinal nonrotation and no other acute pathology. Symptoms spontaneously resolved with conservative management for likely etiology of viral gastroenteritis. At the one-month follow-up, the patient had no residual or recurrent symptoms, with no further interventions planned.

Case report of congenital intestinal malrotation in an adult discovered three months status-post appendectomy

Introduction and importance

Intestinal malrotation is a congenital anomaly primarily diagnosed in children, with limited cases reported in adults. Prompt recognition is necessary to prevent life-threatening complications including bowel ischemia and death. We present a rare case of adult intestinal malrotation highlighting difficulty in diagnosis and surgical management.

Case presentation

A 37-year-old Caucasian woman presented with a 3-day history of worsening diffuse abdominal pain, three months status-post laparoscopic appendectomy. CT scan with contrast of the abdomen and pelvis demonstrated small bowel mesenteric swirling and descending duodenal transition point. Differential diagnosis included intestinal malrotation versus small bowel obstruction. Pre-operatively, the patient expressed frustration with years of abdominal pain and lack of improvement. Treatment with open surgical small bowel detorsion and ligation of the Ladd's bands was performed, after initial laparoscopic intervention was complicated by enterotomy. The patient recovered well post-operatively with final diagnosis of intestinal malrotation with midgut volvulus. Discharge home was delayed due to polysubstance withdrawal. Post-operatively, the patient reported immediate relief of symptoms which persisted at 2-week and 2-month follow-ups.

Clinical discussion

Few reports of congenital malrotation diagnosed in adulthood are reported. This highlights the importance of evaluating all patients for malrotation when the appendix is found outside of the normal positioning in the RLQ, as surgical correction of malrotation is of utmost importance in such patients.

Conclusion

Clinicians should consider intestinal malrotation in adults with recurrent vague abdominal symptoms. To our knowledge, this is the first report of congenital malrotation discovered in an adult after prior appendectomy.

•

Congenital intestinal malrotation diagnosed in adults is scarcely reported.

•

No guidelines exist for the management of malrotation in adult patients.

•

To our knowledge, this is the first report of intestinal malrotation discovered after previous appendectomy.

Intestinal malrotation in one adult patient affected by SARS-CoV-2 infection: occlusion misdiagnosed as COVID gastroenteritis. Case report and literature review

Malrotation of the gut is a rare occurrence, commonly diagnosed during childhood, but occasionally diagnosed in adults.

In children, intestinal obstruction is the most common manifestation, whereas in adult patients, the diagnosis is more challenging since the symptoms are less specific with several episodes of abdominal pain and vomit.

In a particular epidemic period, like the one we are going through, these generic symptoms may mislead to a wrong diagnosis.

We present the case of a young man in which occlusion due to intestinal malrotation has been misinterpreted as gastroenteric symptoms of severe acute respiratory syndrome coronavirus 2 infection, and we also overview the correct Ladd’s technique, commonly performed by pediatrical surgeon, but unusual operation for adult general surgeons.

Intestinal Malrotation, Mesocolic Hernia, and Meckel Diverticulum – Differential Diagnosis of Abdominal Pain in Adults: Case Report and Literature Review

Intestinal malrotation is a congenital anomaly caused by incomplete rotation or absence of rotation of the primitive intestine along the axis of the upper mesenteric artery during embryonic development. Embryonic development and its anatomical variations were described by Dott in 1923.

Intestinal malrotation is a rare condition among adults – prevalent in a mere 0.0001% to 0.19% of the population –, and it may be associated with other anatomical deformities. It can be asymptomatic or manifest with varying intensity, from obstruction to necrosis of intestinal segments. In general, this abnormality is diagnosed in the first year of life; however, symptoms may appear later in life, making diagnosis in adults difficult on account of non-specific symptoms.

In the present study, we report a case of intestinal malrotation associated with chronic non-specific symptoms progressing to mesenteric angina.

Facing the unexpected: unusual causes of mechanical small bowel obstruction in adults

Mechanical small bowel obstruction in adults is a common emergency condition that typically requires hospitalisation and usually acute surgical intervention. The majority of the cases are due to adhesive obstruction or common abdominal wall hernias or relevant related past history. However, the surgeons might face unexpected challenges in this concept due to rare causes of this condition. This paper explores in depth the challenges encountered by the emergency general surgeons in the concept of management of rare causes of mechanical small bowel obstruction in adults through a systematic review and critical analysis of the available evidence, and summarises the essential intra-operative steps that are needed to be taken accordingly. In conclusion, the emergency surgeons should be familiar with the uncommon/rare causes of mechanical small bowel obstruction in adults to avoid serious complications. Successful outcomes are based on the combination of high index of clinical suspicion, familiarity with the standard anatomy and its variations, the use of the appropriate radiological investigations and surgical intervention in a timely manner.

Ladd's band in the adult, an unusual case of occlusion: Case report and review of the literature

INTRODUCTION

Malrotation of gut is a congenital anomaly of foetal intestinal rotation and it is mostly discovered in early childhood as acute intestinal obstruction. This condition is very rare and often silent in adults.

PRESENTATION OF CASE

We present a case of 44-year-old woman admitted with acute abdominal pain. The abdominal CT scan showed ileal conglomerate loops with thickened walls filled of liquid in the right iliac side. Laparotomic Ladd's procedure was performed successfully with division of Ladd's band, adhesiolysis, reconstruction of Treitz's ligament, small bowel resection and Merckel's diverticulum removal. The patient made an unremarkable recovery.

DISCUSSION

We discuss the rarity of intestinal malrotation in adulthood and made a literature review comparison of the therapeutic options available.

CONCLUSION

Intestinal malrotation is a rare entity and adult presentation is even rarer. Some cases are asymptomatic, but when symptomatic a volvulus should be promptly suspected to avoid complications such as bowel ischemia.

Recurrent midgut volvulus in an adult patient - The case for pexy? A case report and review of the literature

•

Intestinal malrotation and midgut volvulus in adulthood are rare events.

•

Reports of recurrence among adults are very scarce. The rate of recurrence and optimal surgical management are yet to be determined.

•

Bowel fixation procedures may be considered in Ladd procedures for adult midgut volvulus in order to reduce recurrence.

Introduction

Intestinal malrotation is a rare condition, with an incidence estimated between 0,2 to 1%. Most cases are diagnosed and treated during childhood. Adult presentations are rare and most adults present with chronic nonspecific complaints.

Midgut volvulus is the most feared complication of intestinal malrotation, far more common among the pediatric than the adult population. Presentation in adulthood with a midgut volvulus accounts for a minority of these patients (15%).

The Ladd procedure is the standard surgical management of midgut volvulus and intestinal malrotation. Most evidence on the outcomes of the Ladd procedure originates from studies on pediatric population and the recurrence among children who have had a Ladd procedure is low (2–7%).

Presentation of case

We report an exceedingly rare case of a patient who presented in adulthood with a midgut volvulus and less than two years after undergoing Ladd procedure presented with a recurrence of the midgut volvulus. The recurrent midgut volvulus was successfully treated by a fixation procedure (cecopexy and duodenopexy).

Conclusion

Reports of midgut volvulus in adult patients are scarce and reports of recurrence even scarcer hence the rate of recurrence among adult patients has yet to be determined. The recurrence rate in some of the available adult series is much higher than the rate reported among children.

Should the rate of recurrence among adult patients prove higher, it poses the question of whether the Ladd procedure should be modified to include bowel fixation when performed in adults.

Midgut volvulus is a rare cause of intestinal obstruction in adults: A case report

•

Midgut volvulus is usually diagnosed in first weeks of life, or even, in many cases, before birth.

•

Incidence of midgut malrotation among pediatrics is 1 in 500 livebirths.

•

Incidence of adult midgut malrotation is reported between 0.0001% and 0.19%.

•

This is case rare presentation in which a 34 year old man was presented. With diagnosis of midgut volvulus underwent laparotomy.

Introduction

The incidence of midgut vovulus is rare in adults. However, a significant number of cases were seen in infant and children.

Presentation of case

We report a case of a 34-year-old male who presented to the emergency room with persistent periumbilical abdominal pain without any other symptoms. Contrast-enhanced CT showed clearly the typical finding of midgut volvulus like whirlpool sign, corkscrew sign, and the superior mesenteric vein to the left of superior mesenteric artery. The patient was planned for Ladd’s procedure and emergency laparotomy performed successfully with an uneventful postoperative recovery.

Discussion

Managing midgut volvulus is based on presentation. In symptomatic cases surgery is the treatment, but in asymptomatic cases, treatment is controversial.

Conclusion

Although midgut volvulus is rare in adults, it should be considered as an intestinal obstruction.

Comparative study of intestinal malrotation in infant, children, and adult in a tertiary care center in India

BACKGROUND

Intestinal malrotation (IM) is an uncommon condition and has varied presentation in different age groups. The study was aimed to evaluate differences in the clinical presentation, diagnosis, treatment, and outcome of IM in infants, children, and adults.

METHODS

Data were collected from records of 79 patients with IM. Based on the age of presentation, these patients were categorized into three age groups: infants (up to 1 year), children (1-18 years), and adults (> 18 years). Follow up data were analyzed during 8 to 16 year after corrective surgery.

RESULTS

The overall age of presentation ranged from 8 days to 60 years. Twenty-eight, 29, and 22 patients belonged to the infant, children, and adult groups, respectively. The classical presentation of IM (bilious vomiting) was significantly higher in the infant compared to the children and adult groups (100% vs. 62% vs. 9.8%; p < 0.001). All infants presented with acute symptoms. However, children and adults had subacute or chronic presentations, respectively. The incidence of volvulus was significantly higher in the infant group than other two groups, (100% vs. 41% vs. 10%; p < 0.001). Doppler ultrasound was highly accurate in infants (100%), whereas contrast-enhanced computed tomography (CECT) abdomen was found to be most useful in adults. Postoperative complications were more common in adults.

CONCLUSION

Intestinal malrotation can present in patients of any age group. An increased awareness about the atypical presentations of this condition among adults may reduce the time to accurate diagnosis of this disease.

Left-sided cecal diverticulitis associated with midgut malrotation

Malrotation of the midgut is generally considered as a pediatric pathology with the majority of patients presenting in childhood. The diagnosis is rare in adults, which sometimes leads to delay in diagnosis and treatment. An index of suspicion is therefore required when dealing with patients of any age group with abdominal symptoms. We present a case of a 26-year-old male who presented with left lower abdominal pain with preoperative computed tomography showing suspected left-sided appendicitis associated with midgut malrotation. The duodenum, small bowel, and cecum were abnormally located, with the presence of a thickened and inflamed appendix with fecalith images. The patient underwent an emergency laparotomy, and ruptured cecal diverticulitis with abscess formation was confirmed. We performed a cecectomy, and the patient did not have an uneventful postoperative recovery. A review of the literature is presented to highlight the rarity of midgut malrotation and the controversies surrounding its surgical management in the adult population with ruptured left-sided cecal diverticulitis.

Computed Tomographic presentation of obstructive jejunal adenocarcinoma associated with celiac disease and incomplete intestinal malrotation

•

Celiac disease is a risk factor for adenocarcinoma and lymphoma.

•

Small bowel adenocarcinoma occurs most often in the proximal intestine.

•

Intestinal malrotation can be complete or incomplete. Prophylactic surgery for incomplete malrotation in asymptomatic patient is not required .

Introduction

Small bowel adenocarcinoma is a rare entity most frequently observed with celiac disease. This is the first case report on the association of celiac disease, small bowel adenocarcinoma and intestinal malrotation.

Case report

A 40 year-old male patient diagnosed with celiac disease since the age of 5 years complained of epigastric pain and vomiting for three days. Computed tomography (CT) showed a significant gastroduodenal dilatation with thickened intestinal wall proximal to the duodenojejunal flexure. The lumen contained a food bezoar in the center. The duodenojejunal angle was abnormally on the right side of the abdomen and the superior mesenteric vein was anterior to the superior mesenteric artery. Endoscopy after aspiration found a hemi-circumferential and irregular mass which bled at the contact of fibroscope. Biopsies showed an adenocarcinoma and small bowel resection was performed.

Discussion

Celiac disease is associated with a high risk of small bowel cancer. The association of incomplete intestinal malrotation, duodenojejunal flexure tumor and celiac disease made the surgery challenging.

Conclusion

Patients with celiac disease should be carefully monitored and endoscopic or radiologic investigations should be carried out in patients with any doubtful symptoms.

Malrotation of midgut in adults, an unsuspected and neglected condition--An analysis of 64 consensus confirmed cases

INTRODUCTION

Malrotation of midgut is considered to be a condition of childhood. This study evaluated malrotation in adults with recurrent abdominal pain (RAP).

METHODS

Sixty-four consensus-confirmed cases of intestinal malrotation were reviewed. The diagnosis was based on radiological criteria, and the consensus was arrived at by at least three of the five authors in any individual case.

RESULTS

Abnormal duodenojejunal junction (DJJ) was a consensus finding in 64 cases referred for RAP. Most were in their fourth decade of life, and 12 were beyond 60 years. Besides RAP, intolerance to food was the next common symptom. Acute intestinal obstruction was seen in 16. Forty-two of 64 patients consented for surgery. Ladd's procedure was the commonest. All patients who underwent surgery were symptom free except for two, of which, one had liver cyst and the other had hernia. Of those who refused surgery (22), all had continued symptoms and 10 patients took alternative therapies. On follow up of initially unwilling patients (for surgery) with abnormal DJJ, only eight consented for surgery; three underwent open Ladd's procedure, and one had laparoscopic Ladd's done.

CONCLUSION

Malrotation is not uncommon as a cause of RAP in adults.

Barber Pole Sign in CT Angiography, Adult Presentation of Midgut Malrotation: A Case Report

Adult midgut volvulus is a challenging diagnosis because of its low incidence and nonspecific symptoms. Diagnostic delay and long-term complaints are frequent in this clinical scenario. We reported a patient referred to our diagnostic imaging unit with intermittent abdominal pain, bloating and episodic vomiting for several years. He underwent barium gastrointestinal transit and abdominal ultrasound, which revealed severe gastric dilatation, food retention and slow transit until a depressed duodenojejunal flexure, with malrotation of the midgut and jejunal loops being located in the right upper quadrant. Computed tomography angiography was performed, showing rotation of the small intestine around the mesentery root, suggestive of midgut malrotation. In addition, an abnormal twisted disposition of superior mesenteric artery with corkscrew appearance was seen, shaping the pole-barber sign which was evident in volume rendering three-dimensional reconstructions. The patient underwent scheduled surgical treatment without any complication and had good outcome after hospital discharge and follow-up. Computed tomography plays an important role in evaluation of adult midgut volvulus. In addition, angiographic reconstructions can help us to assess the anatomic disposition of mesenteric vascular supply. Both of these assessments are useful in preoperative management.

An unusual cause of duodenal obstruction in adults

BACKGROUND

Intestinal malrotation refers to a spectrum of anomalies of midgut rotation and fixation at various stages during early embryonic development. In adults, malrotation manifests itself mainly in chronic non-specific abdominal complaints and may therefore be easily misdiagnosed beyond infancy.

CASE PRESENTATION

We present a case of an 82-year-old Caucasian man with vomiting and abdominal pain owing to malrotation complicated by duodenal obstruction and intestinal ischaemia confirmed by radiologic evaluation and autopsy report.

CONCLUSION

Although intestinal malrotation is generally discovered near birth, our case demonstrates that physicians should consider this diagnosis at advanced age as well. In addition, particularly radiologic findings are supportive in diagnosing malrotation.

Organoaxial partial rotation of duodenum with midgut malrotation in an adult

Midgut malrotation includes a range of developmental abnormalities that occur during fetal intestinal rotation. Manifestations of intestinal malrotation are generally seen in the paediatric population and are uncommon in adults. Symptomatic patients may present with either acute abdominal pain due to midgut volvulus, or chronic abdominal pain due to proximal midgut partial obstruction in the presence of congenital bands. A limited number of paediatric cases of duodenal occlusion due to duodenal malrotation has been previously reported in the medical literature. We herein report the case of a 57-year-old woman who presented with duodenal obstruction due to organoaxial partial rotation of the distal duodenum associated with midgut malrotation. This is probably the first of such a case diagnosed in adulthood reported in the medical literature. Our patient underwent Roux-en-Y duodenojejunostomy and had symptomatic relief following the successful surgery.

Laparoscopic correction of intestinal malrotation in adult

Intestinal malrotation is rare in adults. Patients may present with acute obstruction or chronic abdominal pain. These symptoms are caused by Ladd's bands and narrow mesentery resulting from incomplete gut rotation. Barium, computed tomography (CT) and magnetic resonance imaging (MRI), angiography and sometimes explorative laparotomy are used for diagnosis. Ladd's procedure is the treatment of choice but data about laparoscopic approach in adult is scarce. We report three cases of laparoscopic correction of adult malrotation presenting with chronic abdominal pain. The diagnosis is made by CT/MRI. Laparoscopic Ladd's procedure (release of bands, broadening of mesentery and appendicectomy) was performed via three ports. Procedure time 25-45 min. All patients were discharged on postoperative day 2. At 6 month follow-up, all are symptom free. Laparoscopic Ladd's procedure is an acceptable alternative to the open technique in treating chronic symptoms of intestinal malrotation in adults.

Intestinal malrotation and volvulus in adult life

INTRODUCTION

Midgut volvulus due to intestinal malrotation is a rare cause of intestinal obstruction when occurring in adult life. This paper documents the difficulties in reaching an early diagnosis.

PRESENTATION OF CASE

We describe the case of an 85-year-old man with non-specific abdominal complaints for 20 years, who presented with sudden onset central abdominal pain. An acute median laparotomy under general anaesthesia was performed during which a 360° clockwise rotation of the small bowel around the mesenteric pedicle of the superior mesenteric artery and vein was found.

DISCUSSION

Malrotation is considered any deviation of the normal rotation of the midgut in embryological development, causing intermittent episodes of gastrointestinal obstruction or acute events of midgut volvulus. Although mainly a paediatric diagnosis, some cases do present in adult life. Radiologic investigations include: upper gastrointestinal contrast studies, Doppler sonography and a contrast enhanced CT of the abdomen. If a true malrotation is diagnosed or found by coincidence, a Ladd's procedure is advised, even if the patient is asymptomatic. There is no proven surgical strategy for preventing the recurrence of small bowel volvulus in case of malfixation of the midgut.

CONCLUSION

Non-specific recurrent abdominal complaints in adults of any age should raise suspicion of the possibility of a midgut malrotation or malfixation with or without intermittent volvulus. This case highlights the importance of diagnosis in an early stage.

A case of cancer of the ampulla of Vater accompanied by malrotation

Intestinal malrotation is caused by a developmental anomaly of the embryonic intestine. Most cases develop in neonates, and development in adulthood is rare and difficult to diagnose before surgery. Pancreaticoduodenectomy was performed for cancer of the ampulla of Vater accompanied by incomplete fixation in a 63-year-old male patient. A branch of the superior mesenteric artery was present on the resection line and was deemed likely to cause circulatory disorder in the small intestine, and the duodenum and jejunum were covered with a membranous structure making dissection, anatomical identification, and jejunectomy difficult. Herein, we report the case with a review of the literature.

Recurrent intestinal volvulus in midgut malrotation causing acute bowel obstruction: A case report

Intestinal malrotation occurs when there is a disruption in the normal embryological development of the bowel. The majority of patients present with clinical features in childhood, though rarely a first presentation can take place in adulthood. Recurrent bowel obstruction in patients with previous abdominal operation for midgut malrotation is mostly due to adhesions but very few reported cases have been due to recurrent volvulus. We present the case of a 22-year-old gentleman who had laparotomy in childhood for small bowel volvulus and then presented with acute bowel obstruction. Preoperative computerised tomography scan showed small bowel obstruction and features in keeping with midgut malrotation. Emergency laparotomy findings confirmed midgut malrotation with absent appendix, abnormal location of caecum, ascending colon and small bowel. In addition, there were small bowel volvulus and a segment of terminal ileal stricture. Limited right hemicolectomy was performed with excellent postoperative recovery. This case is presented to illustrate a rare occurrence and raise an awareness of the possibility of dreadful recurrent volvulus even several years following an initial Ladd’s procedure for midgut malrotation. Therefore, one will need to exercise a high index of suspicion and this becomes very crucial in order to ensure prompt surgical intervention and thereby preventing an attendant bowel ischaemia with its associated high fatality.

Unusual presentation of midgut malrotation with incidental nutcracker syndrome in adulthood: case report and literature review

Malrotation of the midgut is generally regarded as paediatric pathology with the majority of patients presenting in childhood. The diagnosis is rare in adults, which sometimes results in delayed diagnosis and treatment. We present the case of a 28-year-old woman who presented with vomiting and mild acute pain in the abdomen. CT scan showed abnormal location of the midgut and abnormal relation of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) and duodenal jejunal flexure, confirming midgut malrotation. Peroperative findings showed the duodenum, small bowel loops located on the right side of the abdomen. The caecum and appendix were located at the midline in the epigastrium with the presence of Ladd's bands. SMA right and anterior to SMV whirled around SMA. Incidentally, the intraoperatively dilated left renal vein was compressed between the SMA and the aorta, which was confirmed retrospectively on CT scan with no symptoms related to the condition.

Midgut malrotation first presenting as acute bowel obstruction in adulthood: a case report and literature review

Malrotation of the midgut is generally regarded as paediatric pathology with the majority of patients presenting in childhood. The diagnosis is rare in adults, which sometimes leads to delay in diagnosis and treatment. A high index of suspicion is therefore required when dealing with patients of any age group with abdominal symptoms. We present a case of a 55-year old man who presented with an acute abdomen with preoperative computed tomography scan and operative findings confirming midgut rotation. The duodenum, small bowel, caecum and appendix were abnormally located, with the presence of classical Ladd's bands. There was no evidence of intestinal volvulus. The patient underwent an emergency laparotomy with an uneventful postoperative recovery.

A review of the literature is presented to highlight the rarity of intestinal malrotation and the controversies surrounding its management in the adult population.

Congenital anomalies of the gastrointestinal tract diagnosed in adulthood--diagnosis and management

INTRODUCTION

Congenital anomalies of the gastrointestinal tract are a significant cause of morbidity in children and less frequently in adults. In rare cases, they may run undetected during childhood and may present during adolescence. These abnormalities include developmental obstructive defects of the duodenum and the small intestine, anomalies of rotation and fixation, intestinal duplications, and anomalies of the colon and rectum.

DISCUSSION

When detected in adulthood, they may require different evaluation and surgical correction. Some of these anomalies should be managed surgically as soon as they cause symptoms. Others may cause persistent problems in adulthood requiring medical management for years. Herein, we present a comprehensive review of all the different ways of diagnosis and management of these anomalies reported in the literature.

A case report of hepatic and renal dysfunction complicating midgut malrotation in an adult

A 39-year-old man had an unusual presentation of jaundice and acute renal dysfunction complicating midgut malrotation. Diagnosis by computed tomography scan enabled prompt surgery and functional correction of the malrotation, with a full return to normal life.
