Small bowel volvulus resulting from a congenital band treated laparoscopically

In recent years, laparoscopy has dramatically changed the approach to the patient with acute abdominal pain. We report the case of a patient with small bowel volvulus caused by a congenital band binding the greater omentum to the mesentery, which was promptly diagnosed and treated using laparoscopy. Early intervention averted irreversible ischemic lesions of the intestine and the need for bowel resection. With the routine use of laparoscopy in the setting of acute abdominal pain, rare affections can be easily diagnosed and effectively treated.

Volvulus of the entire small intestine and its mesentery: Case report

A twenty-eight year old white female was admitted to the hospital with intense intermittent colicky abdominal pain of three days' duration, followed by profuse vomiting. Physical examination revealed bulging around the umbilical area, an appendectomy scar, visible persitalsis, and rebound tenderness. On operation all loops of the small bowel were found to be distended and bluish. Massive evisceration of the small intestine revealed a thick, tense band that was found to be the mesentery itself twisted in a clockwise direction and holding down two loops of small bowel, one fixed, distended, and bluish and another normal in diameter and color. Simple detorsion was performed and the patient's recovery was uneventful.From the preceding report of a case and general considerations, the following conclusions may be made: (1) The case reported is that of a very infrequent type of volvulus. Patients successfully operated upon are exceedingly rare. (2) Precise clinical diagnosis is impossible. The twist of the whole mesentery can be detected only at exploration. Before exploration, one can make only the diagnosis of acute mechanical intestinal obstruction of the strangulating type. (3) Even at exploration, the precise diagnosis can be difficult to make. It has been overlooked by many experienced surgeons. (4) Early operation is the most important factor for success. (5) All the coils of small bowel are found to be distended and showing vascular changes. The cecum is found empty. (6) The twisted mesentery can be detected only after evisceration en masse. (7) The twisted mesentery presents itself as a thick and tense band underneath which two loops pass, one distended and bluish and another with normal color and diameter. (8) Treatment should consist of simple detorsion with minimum trauma and in minimum time. (9) Without operative treatment, mortality is 100 per cent. (10) Authors must be precise in the reporting of their cases. One should mention torsion of the entire small intestine whenever the case happens to be so.     

Laparoscopic diagnosis and management of an abdominal cocoon: a case report and literature review

Abdominal cocoon is a rare cause of small bowel obstruction. It is characterized by the encasement of a variable length of the small intestine by a fibrous membrane. It occurs primarily in females with only few reported cases in males. We report the case of a 42-year-old male with a history suggestive of recurrent attacks of small bowel obstruction over a 6-month period, which used to resolve spontaneously or by conservative measures. At presentation, a mildly tender mobile mass was felt in the right lower part of the abdomen. Computed tomography scan of the abdomen showed clusters of small bowel loops encased within a well-delineated sac. The diagnosis was confirmed by diagnostic laparoscopy. Laparoscopic lyses and release of the entrapped bowel was performed. The postoperative period was uneventful. Follow-up over 18 months showed no clinical evidence of recurrence.     

Mesenteric lipoblastoma presenting as a segmental volvulus

Mesenteric lipoblastoma is a rare tumor and, its presentation as a bowel obstruction with possible midgut volvulus has only been reported once before. A 7-year-old girl presented with nausea and vomiting but a benign abdominal examination. Upper gastrointestinal contrast study demonstrated possible malrotation with midgut volvulus. During emergency laparotomy, segmental small bowel volvulus secondary to a large mesenteric lipoblastoma was found. The lipoblastoma was resected with a segment of small bowel. Resection margins were negative for tumor, and the patient is doing well with no evidence of recurrence.     

Jejunal diverticulosis.

Diverticulosis of the jejunum is an uncommon condition. We found four patients with such diverticula among 40,341 hospital admissions. All four patients presented with acute volvulus of the small bowel. It is suggested that the diverticula bearing segment becomes heavier due to the diverticula and the semisolid jejunal contents consisting of roughage, millet and cereals in the staple diet of our patients. Both factors contribute to small bowel volvulus. Jejunal diverticula may be missed because they are buried between the leaves of mesentery or adherent loops of jejunum. With a patient has vague abdominal symptoms, the possibility of jejunal diverticula should be considered.     

A case report of small bowel obstruction secondary to congenital peritoneal band in adult

IntroductionSmall bowel obstruction (SBO) is common in adult surgical procedures, mainly due to postoperative adhesions. Acute SBO in adults without history of abdominal surgery, trauma or clinical hernia is less common and has various etiologies. Congenital band is an extremely rare cause.Presentation of caseA 56-year-old man was admitted to our hospital with a two-day history of abdominal pain and bilious vomiting. He had no history of abdominal surgery or any other medical problems. A contrast-enhanced CT of the abdomen showed a distention of small bowel loops with transition point in the right hypochondrium. Distended loops of small bowel were located in the left side of the abdomen, whereas collapsed loops was located in the right side. The normal bowel wall enhancement was preserved. After initial treatment with intravenous fluid and nasogastric suction, he was operated. At laparoscopy a band obstructing the ileum was clearly observed. This anomalous band extending from gallbladder to transverse mesocolon caused a small window leading to internal herniation of the small bowel and obstruction. The band was coagulated and divided. Postoperative outcome was uneventful and the patient was discharged on the second postoperative day. There was no recurrence of symptoms on subsequent follow-up.DiscussionCongenital peritoneal bands are not frequently encountered in surgical practice and these bands are often difficult to classify and define. Diagnosis of acute intestinal obstruction due to CPB must be included in the differential diagnosis in any patient with no history of abdominal surgery, trauma, clinical hernia, inflammatory bowel disease or peritoneal tuberculosis.ConclusionDespite technological advances in radiology preoperative diagnosis remains difficult, however the diagnosis of SBO due to CPB must be considered in any patient with no history of abdominal surgery, Trauma or clinical hernia consulting for occlusive syndrome. The laparoscopic approach should be intended initially for its feasibility and benefits.     

Ileosigmoid knotting: a case report and review.

Ileosigmoid knotting, or compound volvulus, has not been reported previously in Australia. A 41 year old woman of Anglo-Saxon origin presented with a short history of extreme abdominal pain that was out of proportion to her physical findings. At operation it was found that her entire ileum was tightly knotted around the redundant, twisted sigmoid colon. Both closed loops were gangrenous and it was impossible to unravel the bowel. She recovered uneventfully following resection and primary anastomosis of both portions of the intestine. Most patients with this uncommon condition have been reported from Finland and eastern Africa. An arrangement of the small bowel and sigmoid colon on long, narrow mesenteries would appear to be a prerequisite. The brevity of the history and the severity of the abdominal pain call for early laparotomy. Prolonged attempts to untie the knot are dangerous. It is safer to divide the ileum at the knot and resect it in order to release the sigmoid colon. Primary anastomosis is feasible where the history is short and the uninvolved intestine is clean and collapsed.     

Primary torsion of the greater omentum

Primary or idiopathic greater omental torsion remains a rare cause of acute surgical abdomen in adults and children. The aetiology is as yet unknown and the treatment of choice, once diagnosis is established, is resection of the torted omentum. We report our experience with three such cases encountered over the last five years, two of which were diagnosed and subsequently managed laparoscopically. The performance of diagnostic laparoscopy for acute abdominal pain of an undetermined origin may lead to an increased detection of this condition and subsequent therapeutic intervention.     

Small bowel volvulus: a review.

Small bowel volvulus is a rare but life-threatening surgical emergency. The aetiology may be primary, as is often seen in Africa and Asia, while in Western countries other predisposing conditions usually initiate the volvulus. Early preoperative investigation and expedient surgical treatment is required if bowel infarction is to be prevented. Central abdominal pain resistant to narcotic analgesia should heighten the suspicion of the diagnosis. The diagnostic value of computerised tomography (CT) scanning in such situations has been emphasised. If the bowel is infarcted resection is required, but the optimum treatment for cases with viable small bowel is uncertain, the alternatives either being resection, fixation, or simple derotation.     

Small bowel obstruction caused by congenital mesocolic hernia: case report

Transmesocolic hernias are extremely rare. Their exact incidence is still unknown. A strangulated hernia through a mesocolic opening is a rare operative finding. Preoperative diagnosis still is difficult in spite of imaging techniques currently available. This is the case of a 4-month-old boy with transmesocolic internal hernia and coincident intestinal malrotation and volvulus of small bowel.

Volvulus of the small intestine caused by right paraduodenal hernia: a case report

This report describes a very rare case of right paraduodenal hernia presenting as volvulus of nonherniated small intestine. A 12-year-old boy presented with sudden onset of lower abdominal pain, and emergency laparotomy was performed on a diagnosis of small intestinal obstruction. Laparotomy confirmed right paraduodenal hernia and volvulus of the small intestine out of the hernia sac.     

Internal transomental herniation with a trapped small bowel mimicking acute appendicitis

INTRODUCTIONInternal herniation with subsequent bowel obstruction is uncommon, and making a correct diagnosis prior to surgery is often difficult.PRESENTATION OF CASEIn this case report we present a man, who suffered from sudden extreme right-sided abdominal pain. The diagnostic workup was inconclusive. Emergency surgery was indicated with a suspicion of acute appendicitis. We found a strangulated ileus caused by an internal herniation of the small intestine through a hole in the greater omentum. The patient had no history of surgery or other physical disorders explaining this finding. The obstruction was resolved and the postoperative clinical course was uncomplicated.DISCUSSIONA thorough diagnostic workup including CT scan would most probably have given the correct diagnosis. However, the clinical course and initiation of the correct treatment would have been delayed significantly.CONCLUSIONWe suggest that the diagnostic workup of patients with unclear lower abdominal pain should be limited and that acute clinical symptoms require rapid laparoscopic evaluation and surgical treatment.     

Clinical aspects and therapy of intestinal non-rotation in adults

The intestinal non-rotation is a rare fetal disorder of the gut torsion. Its manifestation is very rarely seen in the adult, either in form of a volvulus of the midgut or ileocecal with an acute onset, or as chronic recurrent abdominal pain. Each diagnostic or therapeutic delay increases the risk of strangulation and may end as an abdominal disaster. We describe three own cases and we try to elucidate the diagnostic and therapeutic problems. Our proceeding: In the acute symptomatic form the explorative laparotomy with a consequent staging of the abdominal situs is the safest way to get an exact diagnosis. Therapeutically the procedure described by LADD is the best torsion prophylaxis; the ascending colon is sawn to the descending colon. Due to a paratopia, the appendectomy is recommended. In the chronic forms the contrast enema and the gastrointestinal barium study are the main diagnostic procedures. In the operation described by Fitzgerald and the ascending colon and the mesentery of the small bowel are--after incision of the common mesentery--fixed at their anatomical site.     

Jejunal diverticular disease with unborn enterolith presenting as a small bowel obstruction: a case report

Jejunal diverticuli are rare and usually asymptomatic. More commonly, they are seen as incidental findings on CT images, enteroclysis, or during surgery. Complications such as bleeding, perforation, obstruction, malabsorption, diverticulitis, blind loop syndrome, volvulus, and intussusception may warrant surgical intervention. An interesting case of an unborn enterolith (enclosed calculus) from a jejunal diverticulum presenting as a small bowel obstruction is presented. The patient is a 66-year- old woman with no prior history of abdominal surgery who presented with a high-grade bowel obstruction. CT with intravenous barium contrast confirmed the presence of a transition point from dilated to decompressed small bowel in the mid jejunum. At laparotomy, a freely mobile mass was found in this area leading to the bowel obstruction. The mass was removed by making a small enterotomy in the jejunum. While running the small bowel proximally, a small segment of jejunum, approximately 8 cm, containing several diverticuli was found. This bowel obstruction was the result of an unborn enterolith from this segment of bowel. The patient's hospitalization was benign and she was discharged home on postoperative day 4.     

Small bowel obstruction by a congenital band in 16 adults

During embryogenesis, abnormal adhesion of the peritoneal folds induces a congenital band which can cause small bowel obstruction. PATIENTS AND METHODS: From 1987 to 2001, 16 adult patients underwent surgery for small bowel obstruction due to a congenital band. There were 8 men and 8 women with a mean age of 59 years (range 23-90). None presented previous abdominal surgery. RESULTS: Six patients presented acute abdominal pain the month before hospitalization. Among the 16 patients, 9 were operated at admission, and 7 after initial surveillance. Suspected diagnosis before operation was small bowel obstruction in 8 cases (with a diagnosis of congenital band in 3); perforated duodenal ulcer (n = 2); appendicitis (n = 2); mesenteric infarction (n = 1); diverticultis (n = 1); cholecystitis (n = 1); and strangulated hernia (n = 1). During operation performed through laparotomy or laparoscopy, a congenital band was noted in 100% of the cases, associated with intestinal necrosis in 5. One patient died postoperatively. CONCLUSION: Because small bowel obstruction by congenital band is a rare condition, it represents a frequent problem of diagnosis. In this situation, the possibility of intestinal necrosis expose the patient to a possible fatal outcome.

Mesenteric appendicitis strangulating small bowel: an exceptional internal herniation

Primitive internal hernias are a rare cause of intestinal obstruction. They are often paraduodenal even transmesocolic, but only rarely transomental. We present a rare case of an internal abdominal hernia in a young man. The small bowel was strangulated by an intra mesenteric appendicitis. This hernia was revealed by abdominal pain, nausea and vomiting. Plain X-ray of the abdomen showed dilated jejunal and ileal loops with multiple air-fluid levels. The diagnosis of appendicitis was suggested by ultrasound but the internal hernia was found only upon surgical exploration. An appendicectomy and adhesiolysis were performed. The patient recovered fully after 3 days, and had an uneventful postoperative course. The authors discuss the possible cause of this rare intestinal obstruction.     

Strangulated transmesosigmoid hernia as a late complication of a fall from a height: A case report

IntroductionA transmesosigmoid hernia is defined as small bowel herniation through a complete defect involving both layers of the sigmoid mesentery. Blunt trauma injury to the sigmoid mesocolon has been reported only rarely. We herein report a case of a strangulated transmesosigmoid hernia associated with a history of a fall from a height.Presentation of caseA 43-year-old woman presented to our hospital for evaluation of vomiting. She had no history of abdominal surgery but had sustained a complete spinal cord injury and pelvic fracture secondary to a fall from a height 25 years earlier. A computed tomography scan of her abdomen and pelvis demonstrated a closed loop of small bowel in the pelvis, with a zone of transition in the left lower abdomen. Although the cause of the obstruction was difficult to establish, ischemia was strongly suspected; therefore, the decision was made to perform emergency exploratory laparoscopy. During laparoscopy, a loop of ileum was observed to have herniated through a full-thickness defect in the sigmoid mesocolon, consistent with a transmesosigmoid hernia. The herniated loop was strangulated but not gangrenous and was successfully reduced using laparoscopic graspers. The incarcerated small bowel appeared viable and was therefore not resected. The defect was closed with a running suture. The patient had an uneventful postoperative course with no recurrence.Discussion and conclusionAbdominal blunt trauma can cause sigmoid mesenteric rupture resulting in a transmesosigmoid hernia. In the management of transmesosigmoid hernias, laparoscopic herniorrhaphy has the advantage of facilitating simultaneous diagnosis and surgical intervention.
