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

Laparosopy is now a well established tool in abdominal surgery. More often it is used in acute abominal situations. We present our experience with laparoscopy and laparoscopic treatment in patients with acute small bowel obstruction. Although it is technically challenging, in carefully selected patients laparoscopy and laparoscopic treatment is feasible and a valid option for treatment.     

Laparoscopic management of acute small bowel obstruction

BACKGROUND: Conventional surgical management of acute small bowel obstruction involves laparotomy. The laparoscopic approach has not been favoured due to the presumed increased risk of bowel injury. METHODS: A retrospective review of our experience of laparoscopic management of acute small bowel obstruction was undertaken. Nine patients were identified from 1997 to 2003. The aetiology of obstruction was identified laparoscopically in all cases. Eight cases were caused by bands or local adhesions and one patient had a bezoar. RESULTS: Laparoscopic treatment was successful in 78% of patients including one laparoscopy-assisted procedure. Conversion to laparotomy was performed in two patients, one due to difficult adhesiolysis and one due to iatrogenic bowel injury during adhesiolysis. The mean operating time was 74 minutes. There were no postoperative complications and the mean length of hospital stay was 4.3 days. CONCLUSION: This small series demonstrates that laparoscopy can serve as a good diagnostic tool as well as treatment of acute small bowel obstruction. In an appropriately selected patient, laparoscopic management of small bowel obstruction is a feasible therapeutic approach and appears to convey the benefits of a short postoperative hospital stay, reduced postoperative complications and possibly reduced subsequent adhesion formation.     

Laparoscopic management of adhesive small bowel obstruction

Adhesions from prior surgery are the most common cause of small bowel obstruction (SBO) in the Western world. Although laparoscopic adhesiolysis can be performed safely and effectively, the indications and contraindications to the use of laparoscopic techniques in SBO are not clearly defined. The goal of our study was to determine the outcomes of the laparoscopic approach to SBO and discuss patient considerations for its utilization. We retrospectively surveyed all patients undergoing laparoscopic or attempted laparoscopic adhesiolysis performed by the authors between July 1997 and March 2006. Data obtained included patient demographics, clinical and radiologic presentation, and intraoperative and postoperative course. Thirty-three patients underwent laparoscopic adhesiolysis secondary to a SBO. Mean age was 53.6 years (range, 29-84 years) and 64 per cent (21 of 33) were female. Mean body mass index was 30.0 kg/m2 (range, 22.6-46.1 kg/m2). Thirty-one patients (93.9%) had undergone between one and four abdominal surgeries and seven (21.2%) had a previous episode of SBO. There were no patients with peritonitis. Abdominal CT scan was performed preoperatively in 27 patients (81.8%). Laparoscopy diagnosed the site of obstruction in all patients. Twenty-nine patients (88%) were successfully treated laparoscopically. Conversion to laparotomy was required in four cases as a result of dense adhesions and/or a lack of working space. Mean procedural time was 101 minutes (range, 19-198 minutes). There was one intraoperative complication (enterotomy), which was repaired laparoscopically and did not require conversion. Conversion was associated with significantly increased procedural time (129 versus 93 minutes; P = 0.02), but not blood loss or complications. Average times to passage of flatus and first bowel movement were 2.3 days (range, 0.5-5 days) and 3.2 days (range, 1-6 days), respectively. Seven patients (21.2%) had postoperative complications, including wound infection, urinary tract infection, and acute renal insufficiency, all of which occurred in patients completed laparoscopically. One patient had a recurrent SBO 8 months postoperatively managed by repeat laparoscopic lysis of adhesions. Mean postoperative stay was 6 days (range, 1-19 days). There was no hospital mortality. Laparoscopy is safe and feasible in the management of acute SBO in selected patients. It is an excellent diagnostic tool and is therapeutic in most cases.     

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 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 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.     

Laparoscopic approach to small bowel obstruction

Historically, laparotomy and open adhesiolysis have been the treatment of choice for patients requiring surgery with small bowel obstruction (SBO), although laparotomy itself is an independent risk factor for bowel obstruction. Laparoscopy is known to create fewer intra-abdominal adhesions than open laparotomy. The observation that many patients with SBO have isolated adhesive bands has led to the use of laparoscopy as primary treatment of SBO by some authors. Although the laparoscopic approach to SBO has been described, the outcomes and indications are not well established. We will review the available literature regarding the laparoscopic approach to SBO. Additionally, we will describe the technique and make recommendations regarding which patients may be best suited for a trial of laparoscopy for adhesiolysis.     

Laparoscopic adhesiolysis for small bowel obstruction

BACKGROUND: Historically, laparotomy and open adhesiolysis have been the treatment for patients requiring surgery for small bowel obstruction. Laparoscopic adhesiolysis has not gained wide acceptance. The indications and outcomes of laparoscopic adhesiolysis for small bowel obstruction are not well established. The purpose of this paper is to review the literature on laparoscopic adhesiolysis for small bowel obstruction and to discuss patient selection, surgical technique, and outcomes. DATA SOURCES: Medline search from 1980 to 2002. CONCLUSIONS: Laparoscopic adhesiolysis has been shown to be safe and feasible in experienced hands. For selected patients, laparoscopic adhesiolysis offers the advantages of decreased length of stay, faster return to full activity, and decreased morbidity. Patient selection and surgical judgment appear to be the most important factors for a successful outcome.     

Laparoscopic surgery for small bowel obstruction

At the beginning of the laparoscopic surgery, intestinal obstruction was considered an absolute contraindication for this approach, because of the high risk of injuring the bowel. Today, the increased experience allows to apply this method in certain selected cases of small intestine obstruction. We realised a retrospective study, over a period of 7 and a half years (January 1997 - June 2004), regarding the patients admitted and treated in our department for small intestine obstruction, both by open surgery (88 cases) and by laparoscopic surgery (11 cases). We compared the preoperative characteristics of the two subgroups, highlighting the importance of a careful selection of the cases for the success of the laparoscopic approach. We analysed the postoperative evolution of these patients (return of bowel function, postoperative wound evolution, hospital stay, socioeconomic reintegration), which allowed us to draw the conclusion that some of the patients with obstruction of the small intestine may benefit from the advantages of the mini-invasive surgery.     

Laparoscopic treatment of small bowel phytobezoar obstruction

An intestinal bezoar causing obstruction is usually treated by an open approach, either with manual mechanical fragmentation or with enterotomy and removal of the bezoar. In this article, we report the minimally invasive surgical management of a 59-year-old man in whom a bezoar obstructing the small intestine developed at the site of an adhesion from a previous gastric surgery. The bezoar was laparoscopically broken down and milked through the ileocecal valve. In the future, the laparoscopic approach may be the treatment of choice for patients with a bezoar when surgery is indicated.     

Laparoscopic adhesiolysis for small bowel obstruction.

The relatively new field of endoscopic surgery shows much promise and allows alternative treatment options. With increasing numbers of surgeons gaining experience with this technique, new approaches to old conditions are being reported. We present the case of a young female with partial small bowel obstruction secondary to an adhesive band; the condition was readily diagnosed using the laparoscope and treated. We show that in appropriate patient selection, this method is a viable and easily performed alternative to formal laparotomy.     

Laparoscopic adhesiolysis in acute small bowel obstruction

At the beginning of the laparoscopic surgery, intestinal obstruction was considered an absolute contraindication for this approach, because of the high risk of injuring the bowel. Today laparoscopic surgery for small bowel obstruction is still under evaluation. Adhesions are the most common cause of obstruction; although an important proportion of these patients can be nonoperatively treated, some of these require immediate operation. The aim of this review was to evaluate the reliability and immediate results of laparoscopic management of small bowel obstruction by postoperative adhesions. Laparoscopic management of acute small bowel obstruction is feasible, but it is often difficult and may be hazardous. The patients with acute obstruction may be undergo laparoscopy after a careful selection. Morbidity is low if the operation is performed by skilled. The immediate benefit is rapid intestinal motility and shorter hospital stay. The long-term effect is the prevention of small bowel obstruction recurrences by new postoperative adhesions.     

Laparoscopic management as the initial treatment of acute small bowel obstruction.

OBJECTIVES: We prospectively evaluated our experience with laparoscopic management of acute small bowel obstruction (SBO). METHODS: The study group included all patients requiring surgical intervention based on complete mechanical SBO by clinical assessment or who had failed conservative management. Patients with malignant causes were excluded. Experienced laparoscopic surgeons performed all operations. RESULTS: Between January 1998 to January 2003, 61 patients required operative intervention for acute SBO. Causes included adhesions, internal hernia, incarcerated incisional hernia, and inflammatory bowel disease. Laparoscopic techniques (LAP) alone were successfully used to complete 41 cases (67%). Twenty patients (33%) were converted (CONV) to either mini-laparotomy [7 patients (35%)] or standard midline laparotomy [13 patients (65%)]. A single band was identified in 25 patients (41%). Complications occurred in both groups. CONCLUSIONS: We believe all patients requiring surgery in the setting of acute small bowel obstruction should undergo a laparoscopic approach initially. By specifically identifying those patients with a single band as the cause of obstruction, a significant number of patients will be spared a large laparotomy incision. Conversion should not be viewed as failure, but rather, a sometimes necessary step in the optimal management of these patients.     

Laparoscopic management of small bowel obstruction caused by a Sigmoid Mesocolic hernia

Internal hernias involve protrusion of viscera through the peritoneum or mesentery into a compartment in the abdominal cavity. Hernias occurring through the meso-sigmoid are rare and the most common presentation of this entity is an acute small intestinal obstruction. Pre-operative diagnosis is often difficult and the diagnosis is usually made at surgery. Traditionally, open surgery is used to manage a meso-sigmoid hernia. We report a patient with meso-sigmoid hernia causing intestinal obstruction managed successfully by the laparoscopic approach.     

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.     

Laparoscopic versus open surgical management of small bowel obstruction: an analysis of short-term outcomes

Background

Laparoscopy in acute care surgery continues to expand. While adhesive small bowel obstruction (SBO) has traditionally been managed via an open approach, appropriately selected patients may benefit from laparoscopy. The objective of our study was to compare short-term postoperative outcomes in patients with adhesive SBO treated with laparotomy versus laparoscopy.

Methods

Using the ACS NSQIP participant use files (2005–10), patients with a postoperative diagnosis of adhesive SBO were selected for inclusion in this study. Patients with bowel resections or concomitant procedures were excluded. Both univariate analyses and multivariate logistic regression were performed to compare 30-day outcomes in the open and laparoscopic groups.

Results

A total of 4,616 patients with adhesive SBO were identified: 3,697 (80.1 %) and 919 (19.3 %) in the open and laparoscopic groups, respectively. Mean operative time was similar in both groups. The mortality and overall complications were 84 (2.3 %) and 819 (22.2 %), respectively, in the open group compared to 7 (0.8 %) and 81 (8.8 %) in the laparoscopic group, with respective unadjusted odds ratios (ORs) of 0.33 (0.13–0.71, P < 0.01) and 0.39 (0.30–0.49, P < 0.01). The adjusted OR for overall complications was 0.46 (0.37–0.59, P < 0.01) favouring the laparoscopic group. The mean postoperative length of stay (LOS) was 8.4 days compared to 3.8 in the open and laparoscopic groups, respectively (P < 0.01).

Conclusion

The laparoscopic approach to treating adhesive SBO resulted in significantly fewer complications and shorter LOS.
