Is laparoscopy safe and effective for treatment of acute small-bowel obstruction?

Background: Acute small bowel obstruction (SBO) has been a relative contraindication for laparoscopic treatment due to the potential for bowel distention and the risk of enteric injury. However, as laparoscopic experience has increased, surgeons have begun to apply minimal access techniques to the management of acute SBO. Methods: A retrospective review was performed of all patients with acute SBO in whom laparoscopic treatment was attempted. Patients with chronic symptoms and elective admission were excluded. Patients treated by laparoscopy were compared to those converted to laparotomy for differences in morbidity, postoperative length of stay, and return of bowel function as evidenced by toleration of a liquid diet. Results: Laparoscopy was performed in 40 patients for acute SBO. The etiologies of obstruction included adhesions (35 cases), Meckel's diverticulum (two cases), femoral hernia (one case), periappendiceal abscess (one case), and regional enteritis (one case). Laparoscopic treatment was possible in 24 patients (60%), but 13 patients required conversion to laparotomy for inadequate laparoscopic visualization (two cases), infarcted bowel (two cases), enterotomy (four cases), and inability to relieve the obstruction laparoscopically (five cases). There were ten complications—one in the laparoscopic group (pneumonia) and nine in the converted group (prolonged ileus, four cases; wound infection, two cases; pneumonia, two cases; and perioperative myocardial infarction, one case). Respectively, the laparoscopic and converted groups had mean operative times of 68 and 106 min a mean return of bowel function of 1.8 and 6.2 days, and a mean postoperative stay of 3.6 and 10.5 days. Long-term follow-up was available in 34 patients. One recurrence of SBO requiring operation occurred in each group during a mean follow-up of 88 weeks. Conclusions: Laparoscopy is a safe and effective procedure for the treatment of acute SBO in selected patients. This approach requires surgeons to have a low threshold for conversion to laparotomy. Laparoscopic treatment appears to result in an earlier return of bowel function and a shorter postoperative length of stay, and it will likely have lower costs.

Laparoscopic management of acute small bowel obstruction

BACKGROUND: The use of laparoscopy has expanded to include the management of acute abdomen. This study describes the author's experience with laparoscopic management of acute small bowel obstruction. METHODS: From February 1994 through March 1998, 19 patients underwent laparoscopic intervention for acute small bowel obstruction. Their clinical data were analyzed to evaluate the outcome. RESULTS: A total of 19 patients underwent 20 exploratory laparoscopies. The cause of obstruction was diagnosed correctly in 17 of the patients (90%). Fifteen patients (79%) had adhesions, nine of which were postoperative. Of the 19 patients, 13 (68%) had successful laparoscopic treatment. Laparotomy was required in six patients (32%) for various lesions including ileocecal tuberculosis. The average time for laparoscopy was 58 min. The mean postoperative hospital stay was 5 days. There was no morbidity or mortality in this series. CONCLUSIONS: Laparoscopy is a feasible and safe alternative to laparotomy for most patients with acute small bowel obstruction.     

Laparoscopic management of acute small bowel obstruction

Background As minimally invasive surgery gains ground, it is entering realms previously considered to be relative contraindications for laparoscopy. We reviewed our experience with the laparoscopic approach to the management of small bowel obstruction (SBO).Methods From December 1997 to November 2002, 65 patients underwent laparoscopic treatment for SBO. The operating surgeon attempted to identify a transitional point between distended and collapsed bowel and then address the obstruction at that point.Results Postoperative adhesions were the cause of the obstruction in 44 patients. Tumor was identified in five cases, hernia in four, bezoar in three, intussusception in three, acute appendicitis and pseudoobstruction in two cases each, and terminal ileitis in one case. The diagnostic accuracy of laparoscopy was 96.9%. Thirty-four patients (52%) were treated by laparoscopy alone. Thirteen patients (20%) required a small target incision for segmental resection. Eighteen operations were converted to formal laparotomy. The mean laparoscopy time was 40 min (range, 25-160). Patients resumed oral intake in 1-3 days. The complication rate was 6.4%. There were two deaths, but none related to laparoscopy. The mean hospital stay was 4.2 days.Conclusions Laparoscopy is a useful minimally invasive technique for the management of acute SBO. It is an excellent diagnostic tool and, in most cases, a therapeutic surgical approach in patients with SBO. However, a significant number of patients will require conversion.Presented in part at the 10th annual congress of the European Association for Endoscopic Surgery (EAES), Lisbon, Portugal, 2-5 June, 2002     

Laparoscopic management of mechanical small bowel obstruction

Background: Laparoscopy is used increasingly for the management of acute abdominal conditions. For many years, previous abdominal surgery and intestinal obstruction have been regarded as contraindications to laparoscopy because there is an increased risk of iatrogenic bowel perforation. The role of laparoscopy in acute small bowel obstruction remains unclear. Methods: Since 1995, data from patients undergoing laparoscopic surgery have been entered prospectively into a database. Patients who underwent surgery before 1995 were added retrospectively to the same database. The charts of all patients treated surgically for mechanical small bowel obstruction were reviewed. Univariate analysis was performed to identify factors associated with success or failure, especially intraoperative complications, conversion, and postoperative morbidity. Stepwise logistic regression was used to assess for independent variables. Results: This study included 83 patients (56 women and 27 men) with a mean age of 56 years (range, 17–91 years). Conversion was necessary in 36 cases (43%). Laparoscopy alone was successful in 47 patients (57%). Intraoperative complications were noted in 16% and postoperative complications in 31% of the patients. Eight reoperations (9%) were necessary. Mortality was 2.4%. Duration of surgery (p < 0.001) and a bowel diameter exceeding 4 cm (p= 0.02) were predictors of conversion. No risk factor for intraoperative complication was identified. Accidental bowel perforation (p= 0.008) and the need for conversion (p= 0.009) were the only independent factors associated with an increased risk of postoperative complications. Conclusions: Laparoscopic management of small bowel obstruction is possible in roughly 60% of the patients selected for this approach. Morbidity is lower, resumption of a normal diet is faster, and hospital stay is shorter than with patients requiring conversion. No clear predictor of success or failure was identified, but intraoperative complications must be avoided. If the surgeon is widely experienced in advanced laparoscopic surgery and there is a liberal conversion policy, laparoscopy is a valuable alternative to conventional surgery in the management of acute small bowel obstruction.

Laparoscopic management of small-bowel obstruction

Laparoscopy is not generally accepted as an effective, advantageous alternative to formal laparotomy for abdominal emergencies. Its use in patients with previous surgery and intestinal obstruction is often debatable. A retrospective study was performed to analyse the results of the laparoscopic approach for acute small-bowel obstruction in terms of efficacy and safety. From January 2000 to December 2003, 44 non-consecutive patients underwent laparoscopic surgery for radiologically documented small-bowel obstruction. Thirty-nine (89%) had undergone previous abdominal operations (mean number of laparotomies: 2; range 1-5). Twelve were men and 32 women (mean age: 57 years; range 13-91). We retrospectively reviewed the patient data, analysing operative time, need for accessory incision or conversion, length of hospital stay, and intraoperative and postoperative morbidity and mortality. The aetiology was established in 40 patients (91%), and the procedures were completed laparoscopically in 28/44. Mean operative time was 58 min (range 25-160). Six patients required an accessory target incision and 10 patients were converted to formal laparotomy. The reasons for conversion were extent of adhesions (n = 3), problems with laparoscopic view (n = 2), gangrenous bowel (n = 2), locally advanced colon cancer (n = 1), haemoperitoneum (n = 1), and diffuse peritonitis (n = 1). The mean hospital stay was 6 days (range 2-28). Postoperative mortality and morbidity were 2% and 16%, respectively. In conclusion, this study suggest that laparoscopy should be considered early in the clinical course of patients presenting with acute small-bowel obstruction. In most patients definitive treatment is possible, effective and safe, thus justifying the early laparoscopic approach.     

Laparoscopic management of a small bowel obstruction of unknown cause

With the expanding indications for minimally invasive surgery, the management of small bowel obstruction is evolving. The laparoscope shortens hospital stay, hastens recovery, and reduces morbidity, such as wound infection and incisional hernia associated with open surgery. However, many surgeons are reluctant to attempt laparoscopy in patients with significantly distended small bowel and a history of multiple previous abdominal operations. We present the management of a patient with a virgin abdomen who presented with a small bowel obstruction most likely secondary to Fitz-Hugh-Curtis syndrome who was successfully managed with laparoscopic lysis of adhesions.     

Acute pelvic inflammatory disease as a rare cause of acute small bowel obstruction

Introduction: Small bowel obstruction (SBO) is a common presentation to emergency abdominal surgery. The most frequent causes of SBO are congenital, postoperative adhesions, abdominal wall hernia, internal hernia and malignancy.

Patients: A 27-year-old woman was hospitalized because of acute abdominal pain, blockage of gases and stools associated with vomiting. Abdominal computed tomography showed an acute small bowel obstruction without any obvious etiology. In view of important abdominal pain and the lack of clear diagnosis, an explorative laparoscopy was performed. Diagnostic of pelvic inflammatory disease was established and was comforted by positive PCR for Chlamydia Trachomatis.

Results: Acute small bowel obstruction resulting from acute pelvic inflammatory disease, emerging early after infection, without any clinical or X-ray obvious signs was not described in the literature yet. This infrequent acute SBO etiology but must be searched especially when there is no other evident cause of obstruction in female patients. Early laparoscopy is mostly advised when there are some worrying clinical or CT scan signs.     

Emergency laparoscopyrid=""

BACKGROUND: By now, laparoscopic surgery has achieved widespread acceptance among surgeons and, generally speaking, by the public. Therefore, we set out to evaluate whether this technique is a feasible method of treating patients with abdominal emergencies, traumatic or not. To assess the routine use of emergency laparoscopy in a community hospital setting, we undertook a retrospective analysis of an unrandomized experience (presence or absence of a surgeon with laparoscopic experience). METHODS: Between January 1993 and October 1998, 575 emergency abdominal surgical procedures were done in our department. In all, 365 (63.4%) were diagnostic and operative laparoscopy procedures (acute small bowel obstruction: 23 cases; hernia disease: one case; gastroduodenal ulcer disease: 15 cases; biliary system disease: 89 cases; pelvic disease: 237 cases). These cases represent almost 56% of all laparoscopic procedures done during the same period at our institution. Laparoscopy was not performed in patients with a history of a previous abdominal approach to malignant disease, a history of more than two major abdominal surgeries, or massive bowel distension; nor was it used in patients whose general conditions contraindicate this approach. RESULTS: The conversion rate was 6.8%. The morbidity and mortality rates were, respectively, 4.1% and 0.8%. A definitive diagnosis was provided in 95.3% of cases, with the possibility to treat 88.2% of them by laparoscopy. CONCLUSIONS: We consider the laparoscopic approach in patients with abdominal emergencies to be feasible and safe in experienced hands. It provides diagnostic accuracy as well as therapeutic capabilities. Sparing patients laparotomy reduces postoperative pain, improves recovery of GI function, reduces hospitalization, cuts health care costs, and improves cosmetic results. This approach promises to play a significant role in emergency abdominal situations and will certainly become increasingly important in today's health care environment.     

Elective laparoscopy in diagnosis and treatment of recurrent small bowel obstruction

BACKGROUND: To evaluate the feasibility, efficacy, and safety of laparoscopy in diagnosis and treatment of recurrent small bowel obstruction. METHODS: Retrospective analysis of 253 patients who underwent therapeutic laparoscopy for recurrent small bowel obstruction from June 1996 to May 2005 was carried out. Patients with acute small bowel obstruction, bowel obstruction due to tumor, and obstructed inguinal hernias were excluded from analysis. RESULTS: Laparoscopy diagnosed cause of obstruction in all except 3 (1.18%) patients. The etiology included adhesions (38%), incarcerated ventral incisional hernias (32%), Meckel diverticulum (7%), stricture (14%), volvulus (3%), intussusception (4%). One hundred sixty nine patients were managed totally laparoscopically with adhesiolysis. Therapeutic bowel intervention other than adhesiolysis was required in 84 patients, of which 33 procedures were performed totally laparoscopically and remaining 51 procedures were completed with laparoscopically guided target incision. Five patients required conversion to open celiotomy. Iatrogenic enterotomies occurred in 3 patients and small bowel perforation during manipulation occurred in 1 patient. Postoperative procedure-related complications were seen in 44 patients. There was one mortality due to postoperative arrhythmia and cardiac failure. CONCLUSIONS: Laparoscopic diagnosis and treatment of recurrent small bowel obstruction is feasible, safe, and can be performed electively in selected cases.     

Laparoscopic treatment of acute small bowel obstruction*

BACKGROUND: Symptoms of obstruction in the intestinal tract involve the small intestine in three quarters of cases and the large intestine in one-quarter. The most common causes of an acute small intestinal obstruction are postoperative adhesions (64.8%) and strangulated hernias (14.8%). The overall incidence of postoperative small bowel obstruction is 4.6%. Because it offers a conservative and targeted means of removing the obstruction, laparoscopy is increasingly used for acute small bowel obstruction. With proper selection of patients, the success rate is very high. This work presents the selection criteria, technique and results for a three-year period. METHODS: Twenty-one patients, 13 men and 8 women aged 28 to 69 years, underwent surgery between January 2008 and December 2010. Selection criteria for a laparoscopic procedure were anesthesia risk of not more than ASA 3, diameter of the dilatated loop of small intestine of not more than 5 cm, radiological image of a change in caliber as an indication of a focal passage disorder, exclusion of paralytic ileus, and no history of diffuse peritonitis. The patients underwent surgery in general anesthesia. The approach for the first trocar was umbilical in 18 cases and in the right or left flank in three cases, but always with open technique. Three trocars were always used. RESULTS: In 7 patients, there was an isolated band from a previous operation, usually an appendectomy; in 5 cases there were postoperative adhesions and a band. Three patients had a volvulus and in one of them, a 20 cm segment of the small intestine was already gangrenous. Two patients had an incarcerated hernia, one inguinal and one Bochdalek. Two patients had a stenosing tumor in the terminal ileum, one of which was a carcinoid and the other, the first manifestation of a lymphoma. One patient had an endometriosis focus as stenosis focus and another had a massively inflamed Meckel's diverticulum that obstructed passage in the small intestine. Two patients – the volvulus with small intestinal gangrene and the Bochdalek hernia – required conversion to open technique. One patient with diffuse adhesions and a band had to undergo open surgery 10 days later. There was no case of an intraoperative accidental intestinal injury. All the patients who underwent laparoscopy were discharged within a week. Hospitalization was significantly longer for the converted patients. The patient with the Boachdalek hernia died after 26 days of irreversible cardiopulmonary failure. CONCLUSIONS: With strict selection, laparoscopic treatment of small intestinal obstruction is a valuable option in visceral acute surgery. Patients with an isolated focal obstruction seem to benefit from laparoscopic surgery on the basis of reduced perioperative morbidity and short hospitalization.     

The laparoscopic approach in abdominal emergencies: a single-center 10-year experience.

INTRODUCTION: Laparoscopy has rapidly emerged as the preferred surgical approach to a number of different diseases because it allows for a correct diagnosis and proper treatment. In abdominal emergencies, both components of treatment--exploration and surgery--can be accomplished via laparoscopy. The aim of the present work is to illustrate retrospectively the results of a case-control experience with laparoscopic versus open surgery for abdominal emergencies performed at our institution. METHODS: From January 1992 to January 2002, 935 patients (mean age, 42.3+/-17.2 years) underwent emergent or urgent surgery, or both. Of these, 602 (64.3%) were operated on laparoscopically (small bowel obstruction, 28; gastroduodenal ulcer disease, 25; biliary disease, 165; pelvic disease, 370 cases; colonic perforations, 14) based on the availability of a surgical team trained in laparoscopy. Patients with a history of malignancy, more than 2 previous major abdominal surgeries, or massive bowel distension were not treated laparoscopically. Peritonitis was not deemed a contraindication to laparoscopy. RESULTS: The conversion rate was 5.8% and was mainly due to the presence of dense intraabdominal adhesions. Major complications ranged as high as 2.1% with a postoperative mortality of 0.6%. A definitive diagnosis was accomplished in 96.3% of cases, and 94.1% of these patients were treated successfully with laparoscopy. CONCLUSIONS: Even if limited by its retrospective nature, the present experience shows that the laparoscopic approach to abdominal emergencies is as safe and effective as conventional surgery, has a higher diagnostic yield, and results in less trauma and a more rapid postoperative recovery. Such features make laparoscopy an attractive alternative to open surgery in the management algorithm for abdominal emergencies.     

Laparoscopic port site Richter's hernia - An important lesson learnt

Introduction

We report a case of small bowel obstruction with strangulation caused by a port site hernia following a laparoscopic appendicectomy and the successful management of the problem by employing a laparoscopy assisted technique. The aim of this report is to emphasize the importance of fascial closures of trocar sites in order to significantly decrease postoperative morbidity.

Case report

A 31 years old female presented with a classic clinical picture of acute appendicitis. She underwent an uneventful laparoscopic appendicectomy. A 12 mm trocar was used at the umbilical port. On Postoperative day three, the patient developed abdominal distension, crampy abdominal pain, nausea and bilious vomiting. Her white cell count increased to 16,500/mm³, and CRP was 145. X-ray abdomen showed dilated small bowel with multiple air fluid levels. CT scan showed a herniated loop of small bowel into the trocar site with small bowel obstruction. Laparoscopy was done to confirm the Richter''s hernia into trocar site with small bowel obstruction. The bowel loop could not be reduced laparoscopically. Limited exploration of the trocar site confirmed findings with necrosis of the antimesenteric portion of the small bowel. A limited bowel resection and anastomosis was performed. The patient had an uneventful recovery.

Conclusion

Most port site hernias present within 10 days of the primary procedures, delayed hernias have been reported. CT scan is a helpful adjunct to differentiate port site hematoma from incarcerated small bowel. The knowledge of such a complication and its early diagnosis are important to avoid complications.     

Prevention of adhesions by bioresorbable tissue barrier following laparoscopic intraabdominal mesh insertion

Intraabdominal adhesions represent a significant problem because of the morbidity associated with adhesive disease, including small bowel obstruction, difficulties in reoperative surgery, and possibly chronic pain. Coating solution of sodium hyaluronate (Sepracoat; Genzyme Production-Surgical Products, Cambridge, MA) was studied in New Zealand white rabbits to determine its potential role for prevention of postoperative adhesions following laparoscopic intraabdominal mesh insertion. A 2-cm polypropylene mesh was inserted laparoscopically to the left iliac fossa and fixed to anterior abdominal wall using a single prolen suture. Group 1 (n = 10) acted as the control group. Mesh was coated using 4% sodium hyaluronate in phosphate buffered saline (Sepracoat) in Group 2 (n = 10). Fourteen days later, all animals underwent diagnostic laparoscopy, and findings were recorded. All animals then were killed, the abdominal cavities were inspected, and adhesions were graded from 0 to 4. All meshes were removed and sent for histologic examination. The degrees of inflammation, fibrosis, and congestion were scored. No adhesions were seen on trocar sites on both groups. Eight of 10 animals in the control group and 5 of 10 animals in the study group had intraabdominal adhesions. The scoring of adhesions revealed that study group had only one (10%) significant adhesion, whereas the control group had eight (80%; < 0.001). Our study suggests that the Sepracoat reduces the incidence and severity of abdominal adhesions following laparoscopic mesh insertion and should be considered as a prophylactic agent, especially in those undergoing laparoscopic transabdominal mesh repair for hernia.     

Diagnosis and Management of Internal Hernias after Laparoscopic Gastric Bypass

BACKGROUND: Internal hernia is a known complication of laparoscopic Roux-en-Y gastric bypass (LRYGBP). However, no consensus exists regarding optimal diagnostic modality and management. We reviewed the literature and our own experience, and present an algorithm for the diagnosis and management of internal hernia after LRYGBP. METHODS: A retrospective review of 290 retrocolic LRYGBPs was performed to identify those who developed postoperative small bowel obstruction due to internal hernia. Demographics, clinical symptoms, radiologic characteristics, and operative outcomes were analyzed to determine clinical and radiological diagnostic accuracy. RESULTS: Over a 43-month period, 11 out of 290 (3.79%) post-LRYGBP patients with symptoms suggestive of a small bowel obstruction underwent operative exploration. The most common clinical symptoms included intermittent abdominal pain, and/or nausea/vomiting. All patients were initially explored laparoscopically. Etiology of obstructions included internal hernias--6 [at the transverse mesocolon (n = 1), Petersen's space (n = 2), and at the jejunojejunostomy (n = 3)], adhesions (n = 4) and a negative laparoscopy (n = 1). The mean time for development of internal hernias was 13.7 months. Mean loss of BMI units at time of re-operation was 17 kg/m2. Of the 6 patients with internal hernia, 2 (30%) had normal preoperative radiological work-up. On review of the preoperative films by the surgeon, signs of internal herniation were seen in all the patients. Management included initial laparoscopic exploration, lysis of adhesions, reduction of internal hernia and closure of mesenteric defects in all the patients. There were 2 conversions to laparotomy. CONCLUSION: Small bowel obstruction in the post-LRYGBP patient is difficult to diagnose, especially when due to an internal hernia. Most patients present with intermittent abdominal pain and/or nausea. The most frequently used radiologic study is CT scan, which is most accurate when reviewed by the bariatric surgeon preoperatively.     

Laparoscopic approach to postoperative adhesive obstruction

Background Some authors have assessed the feasibility of laparoscopy in the treatment of postoperative adhesive obstruction, but conclusions about its effectiveness are related to different selection criteria used for surgery. This paper reports on our experience in laparoscopic adhesiolysis and analyses the results on the basis of the selection criteria used.Methods From January 1993 to December 2001, 65 patients were submitted to laparoscopic adhesiolysis for small bowel obstruction according to specific selection criteria. Of the 65 patients, 40 were admitted for acute obstruction and 25 for chronic or recurrent transit disturbances. Correlation between historical and clinical data and the results of surgical treatment were statistically analyzed.Results The procedure was completed by laparoscopy in 52 patients (conversion rate: 20%). Mean postoperative stay was 4.4 days with a 12.3% morbidity and no mortality. Recurrence rate was 15.4%; a single correlation was found between recurrence and age.Conclusions Laparoscopic adhesiolysis in the treatment of small bowel obstructions seems to be effective; further studies are required to define selection criteria for surgery and confirm real advantages in terms of recurrences.     

Laparoscopic treatment of small intestine obstruction]

Laparoscopic surgery for small bowel obstruction is still under evaluation. A review of the literature retrieved over 200 published cases. Technically, the open laparoscopy procedure seems mandatory to avoid bowel injuries. Grasping the enlarged bowel and using monopolar cautery should be avoided. The surgeon should also be sure that at the end of the procedure adhesiolysis was correct. Evaluation of the results must also take into account that most studies were retrospective and included few patients. The cumulative effectiveness rate of laparoscopy was 60%. Failures were mainly due to multiple adhesions, iatrogenic perforations to the intestine, and colonic cancers not recognized before the procedure. There was no prospective study comparing laparoscopy with laparotomy. Finally, it is not proved at present that laparoscopy prevents the recurrence of adhesions after digestive surgery. Owing to the results of the literature, laparoscopic surgery for acute small bowel obstruction does not appear as based on fact.     

Laparoskopie bei Dünndarmileus

Today laparoscopic procedures are routinely performed in patients with intestinal adhesions from previous abdominal surgery. Does laparoscopy have a potential benefit in acute small-bowel obstruction? Theoretically, a lower rate of wound complications and incisional hernias, as well as less subsequent adhesions with a lower incidence of recurrent intestinal obstruction, can be expected. However, laparoscopy is successful in only 50-70% of selected patients, thereby representing the highest rate of conversion in minimally invasive surgery. Laparoscopic management of severe abdominal distension with massively dilated and fragile small-bowel or dense adhesions is extremely difficult even when performed by experienced surgeons. Significantly prolonged operating time, the high risk of bowel injury (> 6-10%) and an increased frequency of early reoperations jeopardize the patient's safe outcome. However, in strictly selected patients the laparoscopic approach may be promising. In acute intestinal obstruction without a history of previous abdominal surgery, laparoscopy is--in the absence of adhesions--an excellent diagnostic tool and may also be a successful therapeutic modality in a variety of bowel-obstruction etiologies. Furthermore, the laparoscopic option should be considered in patients who previously had undergone small laparotomies (e.g., appendectomy) or laparoscopic surgery. We recommend "postlaparoscopic" intestinal obstruction as the ideal case for laparoscopic reexploration. Incarcerated hernias at the site of trocar insertion or adhesions due to peritoneal tears are easily identified as the cause of obstruction and successfully cured with the laparoscope. In conclusion, we advocate the laparoscopic approach in acute small-bowel obstruction exclusively for selected patients. Clinical studies are required to define appropriate surgical indications objectively.     

Enteroclysis-guided laparoscopic adhesiolysis in recurrent adhesive small bowel obstructions

The aim of this study was to point out the efficiency of enteroclysis assay in localization of intraabdominal adhesions that impede small bowel transit in patients with recurrent adhesive small bowel obstruction who underwent laparoscopic partial adhesiolysis. Between January 1998 and June 2001, 15 selected patients with recurrent adhesive small bowel obstructions were treated successfully by medical means and evaluated with enteroclysis to define the pathologic adhesive site that impeded bowel transit. If the results of enteroclysis were indicative, they underwent laparoscopic partial adhesiolysis. The mean duration of the laparoscopic procedure was 99 minutes. In one patient conversion to laparotomy occurred because of excessive adhesions, and in another patient a small bowel injury occurred and enterorrhaphy was performed laparoscopically. Mean postoperative hospital stay was 4 days. During a mean follow-up of 17.2 months (range, 6-39), there was no delayed morbidity or recurrence. Identification of the small bowel site of recurrent obstruction with enteroclysis permits limited laparoscopic adhesiolysis. This approach may be a rational alternative to not only open procedures but also complete laparoscopic adhesiolysis without enteroclysis.     

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.
