Outcomes of laparoscopic management of acute small bowel obstruction: a 7-year experience of 110 consecutive cases with various etiologies

Purpose

Laparoscopic surgery is emerging as an alternative to open surgery for treating acute small bowel obstruction (SBO). While postoperative adhesion is the most frequent etiology, the optimum treatment for all types of SBO needs to be evaluated.

Methods

A retrospective review was performed of 110 consecutive patients who underwent laparoscopic surgery at our institution between 2009 and 2015. The short-term outcomes included perioperative factors, while the long-term outcome included the recurrence rate.

Results

Of the 110 patients, 55 were female. The median age at surgery was 69.5 years. Laparoscopic surgery was completed in 91.8 %. The median operative time was 82 min, median amount of bleeding was 0 ml, and median postoperative hospital stay was 8 days. Intraoperative major organ injury was seen in 2.7 %. The complication rate (Clavien–Dindo ≥ class II) was 8.2 %, and the mortality rate was 3.6 %. The recurrence rate was 8.2 %. Only dense and matted adhesion was a predictive factor for conversion (OR 30.244).

Conclusion

Good short-term outcomes and feasible long-term outcomes were achieved with a laparoscopic approach to treating acute SBO. It was a safe and effective method, especially in patients with isolated bands, simple enteral angulation, and foreign body or tumor, while dense and matted adhesions were still challenging.

     

Bidirectional Jejunojejunal Anastomosis Prevents Early Small Bowel Obstruction Due to the Kinking After Closure of the Mesenteric Defect in the Laparoscopic Roux-en-Y Gastric Bypass

Background

The closure of the mesenteric defects (CMD) in Roux-en-Y gastric bypass (RYGB) reduces the risk of small bowel obstruction (SBO) due to internal hernia but might be associated with an increased risk of early SBO triggered by the jejunojejunal anastomosis (JJS) kinking. The aim of this study was to assess how enlarging the JJS with a bidirectional linear stapling can aid in avoiding the risk of early SBO by kinking.

Materials and Methods

This retrospective cohort study concerns 1327 patients who underwent RYGB with CMD between May 2007 and August 2016. The first 626 patients (group A) had a unidirectional JJS. The following 701 patients (group B) had a bidirectional side-to-side JJS and a hand-sewn closure of the remaining defect. We compared early SBO between the two groups.

Results

Eleven (1.75%) early SBO due to the JJS kinking occurred in group A, whereas none occurred in group B (p?=?0.0012). Thirty-nine early postoperative complications happened in group A versus 32 in group B (p?=?0.17). Nine (1.2%) digestive bleedings occurred in group B versus two (0.3%) in group A (OR?=?4.05 [0.87–18], p?=?0.054). Average operating time was 81 min [37–330] in group A and 77 min [33–240] in group B.

Conclusion

Enlarging the JJS with a bidirectional linear stapling is associated with a reduced risk of early SBO due to the anastomosis kinking. However, it could be related to an increased risk of digestive bleedings.

     

Clinical Effect of Water-Soluble Contrast Agents for Small Bowel Obstruction in the Virgin Abdomen

Background

Several studies have investigated the diagnostic and therapeutic role of water-soluble contrast agents (WSCAs) in adhesive small bowel obstruction (SBO). However, the clinical effect of WSCA for SBO without previous intraabdominal operation (i.e., virgin abdomen, VA) is unclear. The aim of this study was to clarify the clinical effect of WSCA for SBO in the VA.

Methods

Between January 2008 and December 2015, 838 consecutive patients with SBO were initially managed with WSCA and were included in the study. Abdominal X-rays were taken 5 h after administration of 100 ml WSCA and classified into complete/incomplete obstruction groups. The medical records of the patients with SBO were retrospectively analyzed and divided into two groups of patients with VA or non-VA.

Results

A total of 44 and 794 VA and non-VA patients were identified, respectively. Six VA patients (13%) and 121 non-VA patients (15%) were classified with complete obstruction (p = 1.000) and subjected to operative exploration on the same day. There were no significant differences in the duration of nasogastric tube decompression (2.2 versus 2.5 days, p = 0.400) and intervals until the initiation of oral intake (2.4 versus 2.6 days, p = 0.553) between the VA and non-VA groups. The overall operative rate was 16% in the VA and 17% in the non-VA groups (p = 1.000). Compared with non-VA, VA was associated with shorter hospital stays (9.6 versus 11.3 days, p = 0.006).

Conclusions

WSCA for SBO in the VA is as effective as in non-VA patients in terms of a therapeutic strategy.

     

Racial Disparities in Readmissions for Patients with Inflammatory Bowel Disease (IBD) After Colorectal Surgery

Background

The incidence of inflammatory bowel disease (IBD) in minorities is increasing, and health outcome disparities are becoming more apparent. Our aim was to investigate the contribution of race to readmissions in IBD patients undergoing colorectal surgery.

Design

The National Surgical Quality Improvement Program database from 2012 to 2013 was queried for all patients with IBD undergoing elective colorectal surgery. After stratifying by race, unadjusted univariate and bivariate comparisons were made. Primary outcome was all-cause 30-day readmission. Predictors of readmission were identified using multivariable logistic regression.

Results

Of the 2523 patients with IBD who underwent elective colon surgery, 15.0 % were readmitted within 30 days of index operation. Black patients constituted 7.7 % of the entire cohort. Black patients were significantly different in smoking status (27 vs. 22 %) and Crohn’s diagnosis (84 vs. 73 %) (p?<?0.05). Black patients had significantly higher readmission rates (20 vs. 15 %) and longer length-of-stays (8 vs. 6 days) after surgery (p?<?0.05). On multivariable analysis, black race remained a significant predictor for 30-day readmissions in patients with IBD (odds ratio 1.6, 95 % confidence interval 1.1–2.5).

Conclusions

Black patients with IBD have an increased risk for readmission after colorectal surgery. Efforts to reduce readmissions need to target not only well-studied risk factors such as postoperative complications, but also investigate non-NSQIP-measured elements such as social and behavioral determinants of health.

     

Computed tomography findings of internal hernia after gastric bypass that may precede small bowel obstruction

Purpose

This study evaluates computed tomography signs of internal hernia in gastric bypass patients, including several previously unreported signs suggestive of internal hernia.

Methods

Eighteen patients with surgically proven internal hernia were included in the study cohort. The signs analyzed included the mesenteric swirl, hurricane eye, mushroom sign, and dilated small bowel loops, as well as previously non-investigated signs such as bowel wall edema, engorged mesenteric vessels, engorged mesenteric lymph nodes, and hazy mesenteric fat. We also separately examined internal hernia patients without overt small bowel obstruction (SBO), since these are the patients most likely to get overlooked by radiologists.

Results

The most prevalent sign in all internal hernia patients was mesenteric vessel engorgement, seen in approximately 79–84 % of patients overall and 73–75 % of patients without overt SBO. The level of agreement between our two readers for the eight total signs reviewed was all moderate to substantial (using Cohen kappa values), reflecting their reliability as markers of internal hernia. The highest level of agreement was seen in vessel engorgement at 0.91, followed by three other signs [hurricane eye, SBO, bowel edema] with levels of agreement at 0.86.

Conclusions

We conclude that more subtle signs of internal hernia should be included in radiologist search patterns for patients with internal hernia, especially those presenting multiple times for abdominal pain, as these may reflect surgically correctable intermittent herniations.

     

Small bowel obstruction and incisional hernia after laparoscopic and open colorectal surgery: a meta-analysis of comparative trials

Introduction

Recent studies show contrasting data on the impact of laparoscopy on long-term complications such as the occurrence of small bowel obstruction (SBO) and incisional hernia (IH). The objective of the study was to assess the impact of the laparoscopic approach on the occurrence of SBO and IH after colorectal resection.

Methods

Two trained investigators independently searched MEDLINE, Embase, PubMed, and the Cochrane Central Register of clinical trials for studies comparing laparoscopy to open surgery for mid- to long-term outcomes after colorectal surgery. No language restriction was set. Sensitivity analyses for study design and quality, conversion rate, type of procedure (colon or rectal surgery), and length of follow-up were performed.

Results

Eleven RCTs and 14 non-RCT comparative studies for a total of 6540 patients were included in the analysis. Laparoscopy was associated with a significant reduction in the occurrence of SBO (RR 0.57, [95 %CI 0.42–0.76], 16 trials) and IH (RR 0.60, [95 %CI 0.50–0.72], 19 trials). Sensitivity analysis including only RCTs confirmed the reduction in SBO (RR 0.58, [95 %CI 0.39–0.87], 8 trials), while the difference was close to significance for IH (RR 0.76, [95 %CI 0.56–1.03], 7 trials). Sensitivity analysis including only studies with conversion rate lower than 15 % showed a significant protective effect of laparoscopy for both SBO (RR 0.53, [95 %CI 0.37–0.77], 11 trials) and IH (RR 0.58, [95 %CI 0.47–0.72], 12 trials). No significant difference between laparoscopy and open surgery was found when the analysis was limited to studies with conversion rate >15 % (SBO: RR 0.60 [0.32–1.12], IH: RR 0.70 [0.46–1.06]). Length of follow-up did not substantially impact on results.

Conclusion

Laparoscopic surgery is associated with a significant reduction in both SBO and IH compared to the open approach. A low conversion rate in the laparoscopic group plays a key role for reduction in both SBO and IH.

     

Clinical features of patients with pars defects identified in adulthood

Purpose

Lumbar spondylolysis is considered a stress fracture of the pars interarticularis that occurs during growth. However, it is sometimes insidious and identified in adults as pseudoarthrosis, the terminal-stage of spondylolysis. The purpose of this study was to identify the clinical features of patients with terminal-stage spondylolysis that first manifested during adulthood.

Patients and methods

Thirty-six patients (21 men, 15 women; mean age 55.8 years; age range 25–77 years) with low back pain (LBP) were studied. In all patients, lumbar spondylolysis had not been diagnosed until the first visit to our hospital. Patient data collected were history of athletic activity and LBP during their growth period and radiological findings, such as spinal level, displacement, and spina bifida occulta (SBO).

Results

Among the 36 patients, including a patient with multi-level spondylolysis (L4 and L5), a total of 37 vertebrae with terminal-stage spondylolysis were identified. Twenty-three (89.2 %) of the 37 vertebrae had L5 spondylolysis. Sixteen patients (44.4 %) had no history of athletic activity, 26 (72.2 %) had no experience of LBP during their growth period, and 14 (38.9 %) had neither. Twenty of the 37 vertebrae (70.4 %) involved displacement (grade 1 = 14; grade 2 = 6). In nine patients (25.0 %; eight men, one woman), SBO of the sacrum was accompanied by L5 spondylolysis.

Conclusions

Approximately 90 % of patients with terminal-stage spondylolysis that was first diagnosed in adulthood involved the L5. Also, about 40 % had no history of athletic activity or experience of LBP during their growth period. In addition, only some patients with L5 spondylolysis had SBO, and all but one of these patients was male. This suggests that male patients with L5 spondylolysis may have some congenital predisposition.

     

Impact of Bariatric Surgery on Outcomes of Patients with Inflammatory Bowel Disease: a Nationwide Inpatient Sample Analysis, 2004–2014

Purpose

There is a paucity of data regarding the benefits of bariatric surgery in patients with inflammatory bowel disease (IBD). The primary aim of this study was to evaluate the role of bariatric surgery on clinical outcomes among hospitalized patients with IBD.

Materials and Methods

The United States (US) National Inpatient Sample database was queried between 2004 and 2014 for discharges with co-diagnoses of morbid obesity and IBD. Hospitalizations with a history of prior-bariatric surgery were also identified. The primary outcome was in-hospital mortality. Secondary outcomes included renal failure, under-nutrition, thromboembolic events, strictures, fistulae, length of stay, and hospitalization costs. Using Poisson regression, adjusted incidence risk ratios (IRR) were derived for clinical outcomes in patients with prior-bariatric surgery compared to those without bariatric surgery.

Results

Among 15,319 patients with a discharge diagnosis of IBD and morbid obesity, 493 patients (3.2%) had bariatric surgery. From 2004 to 2014, the proportion of obese IBD patients that underwent bariatric surgery declined (5.2 versus 3.1%). In a multivariable analysis, prior-bariatric surgery was associated with decreased IRR for renal failure, under-nutrition, and fistulae formation in morbidly obese IBD patients [(IRR 0.1; 95% CI 0.02–0.3; P < 0.001), (IRR 0.2; 95% CI 0.05–0.8; P = 0.03), and (IRR 0.1; 95% 0.2–08; P = 0.03), respectively]. Bariatric surgery did not influence mortality (P = 0.99).

Conclusions

Despite a gradual increase in morbid obesity among patients with IBD, there has been a decrease in proportion of overall bariatric surgeries. Bariatric surgery appears to reduce morbidity in obese patients with IBD.

     

Is Modern Medical Management Changing Ultimate Patient Outcomes in Inflammatory Bowel Disease?

Background

The impact of modern medical management of inflammatory bowel disease (IBD) on surgical necessity and outcomes remains unclear. We hypothesized that surgery rates have decreased while outcomes have worsened due to operating on “sicker” patients since the introduction of biologic medications.

Methods

The Nationwide Inpatient Sample and ICD-9-CM codes were used to identify inpatient admissions for Crohn’s disease and ulcerative colitis. Trends in IBD nutrition, surgeries, and postoperative complications were determined.

Results

There were 191,743 admissions for IBD during the study period. Surgery rates were largely unchanged over the study period, ranging from 9 to 12 % of admissions in both Crohn’s disease and ulcerative colitis. The rate of poor nutrition increased by 67 % in ulcerative colitis and by 83 % in Crohn’s disease. Rates of postoperative anastomotic leak (10.2–13.9 %) were unchanged over the years. Postoperative infection rates decreased by 17 % in Crohn’s disease (18 % in 2003 to 15 % in 2012; P?<?0.001) but did not show a trend in any direction in ulcerative colitis.

Conclusions

Rates of IBD surgery have remained stable while postoperative infectious complications have remained stable or decreased since the implementation of biologic therapies. We identified an increase in poor nutrition in surgical patients.

     

Laparoscopic inguinal hernioplasty after robot-assisted laparoscopic radical prostatectomy

Purpose

To evaluate the efficacy and safety of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair in patients who have undergone robot-assisted laparoscopic radical prostatectomy (RALP).

Methods

From July 2014 to December 2016, TAPP inguinal hernia repair was conducted in 40 consecutive patients who had previously undergone RALP. Their data were retrospectively analyzed as an uncontrolled case series.

Results

The mean operation time in patients who had previously undergone RALP was 99.5 ± 38.0 min. The intraoperative blood loss volume was small, and the duration of hospitalization was 2.0 ± 0.5 days. No intraoperative complications or major postoperative complications occurred. During the average 11.2-month follow-up period, no patients who had previously undergone prostatectomy developed recurrence.

Conclusions

Laparoscopic TAPP inguinal hernia repair after RALP was safe and effective. TAPP inguinal hernia repair may be a valuable alternative to open hernioplasty.

     

No difference in flexion power despite iliopsoas fatty degeneration in healed hip fractures with large lesser trochanter displacement

Objective

To evaluate iliopsoas atrophy and loss of function after displaced lesser trochanter fracture of the hip.

Design

Cohort study.

Setting

District hospital.

Patients

Twenty consecutive patients with pertrochanteric fracture and displacement of the lesser trochanter of?>?20 mm.

Intervention

Fracture fixation with either an intramedullary nail or a plate.

Outcome measurements

Clinical scores (Harris hip, WOMAC), hip flexion strength measurements, and magnetic resonance imaging findings.

Results

Compared with the contralateral non-operated side, the affected side showed no difference in hip flexion force in the supine upright neutral position and at 30° of flexion (205.4 N vs 221.7 N and 178.9 N vs. 192.1 N at 0° and 30° flexion, respectively). However, the affected side showed a significantly greater degree of fatty infiltration compared with the contralateral side (global fatty degeneration index 1.085 vs 0.784), predominantly within the psoas and iliacus muscles.

Conclusion

Severe displacement of the lesser trochanter (>?20 mm) in pertrochanteric fractures did not reduce hip flexion strength compared with the contralateral side. Displacement of the lesser trochanter in such cases can lead to fatty infiltration of the iliopsoas muscle unit. The amount of displacement of the lesser trochanter did not affect the degree of fatty infiltration.

Level of evidence

Task Shifting: The Use of Laypersons for Acquisition of Vital Signs Data for Clinical Decision Making in the Emergency Room Following Traumatic Injury

Importance

In resource-limited settings, identification of successful and sustainable task-shifting interventions is important for improving care.

Objective

To determine whether the training of lay people to take vital signs as trauma clerks is an effective and sustainable method to increase availability of vital signs in the initial evaluation of trauma patients.

Design

We conducted a quasi-experimental study of patients presenting with traumatic injury pre- and post-intervention.

Setting

The study was conducted at Kamuzu Central Hospital, a tertiary care referral hospital, in Lilongwe, Malawi.

Participants

All adult (age ≥ 18 years) trauma patients presenting to emergency department over a six-month period from January to June prior to intervention (2011), immediately post-intervention (2012), 1 year post-intervention (2013) and 2 years post-intervention (2014).

Intervention

Lay people were trained to take and record vital signs.

Main outcomes and measures

The number of patients with recorded vital signs pre- and post-intervention and sustainability of the intervention as determined by time-series analysis.

Results

Availability of vital signs on initial evaluation of trauma patients increased significantly post-intervention. The percentage of patients with at least one vital sign recorded increased from 23.5 to 92.1%, and the percentage of patients with all vital signs recorded increased from 4.1 to 91.4%. Availability of Glasgow Coma Scale also increased from 40.3 to 88.6%. Increased documentation of vital signs continued at 1 year and 2 years post-intervention. However, the percentage of documented vital signs did decrease slightly after the US-trained medical student and surgeon who trained the trauma clerks were no longer available in country, except for Glasgow Coma Scale. Patients who died during emergency department evaluation were significantly less likely to have vital signs recorded.

Conclusions and relevance

The training of lay people to collect vital signs and Glasgow Coma Scale is an effective and sustainable method of task shifting in a resource-limited setting.

     

Can postoperative renal dysfunction be predicted by measuring intraoperative glomerular filtration rate in patients undergoing coronary artery bypass grafting without cardiopulmonary bypass? A pilot study

Objective

Currently, there is no effective paradigm to identify patients who are at risk for renal dysfunction following cardiac surgery. The specific mechanisms of renal injury during surgery are incompletely understood. The aim of the study was to evaluate whether postoperative renal dysfunction can be predicted from intraoperative glomerular filtration rate (GFR).

Design

This is a prospective study.

Setting

The study was conducted in a tertiary care multi-specialty hospital.

Participants and interventions

GFR was measured in 24 patients (mean age 56.6 ± 11.09 years, 20 male) undergoing elective off-pump coronary artery bypass grafting during preoperative period, intraoperative period, 24 h after surgery (ICU GFR), and on the fifth postoperative day (final GFR ).

Measurements and main results

Patients were divided into two groups depending upon changes in intraoperative GFR. Group 1 (n = 10): who had a rise in intraoperative GFR in comparison with preoperative baseline measurement. All these 10 (41.7 %) patients with a rise in intraoperative GFR had an uneventful hospital course and achieved an improvement in final GFR. Group 2 (n = 14): 14 (58.3 %) patients had a fall in intraoperative GFR (mean 36.4 %) in comparison with preoperative baseline value. Of these 14 patients, 1 patient required dialysis support and 3 patients required ionotropic support. Among these 14 patients in group two, 7 had deterioration in final GFR (mean 28.7 %), when compared to preoperative baseline value.

Conclusion

Postoperative renal dysfunction can be predicted from intraoperative GFR. Patients who have a rise in intraoperative GFR do not develop postoperative renal dysfunction, and only patients with intraoperative fall in GFR are at risk of postoperative renal dysfunction.

     

Subcutaneous dissection area contributes less to endoscopic thyroidectomy-related invasiveness

Objective

To clarify the contribution of the subcutaneous area during breast approach endoscopic thyroidectomy (BAET), with regard to invasiveness-related outcomes.

Methods

Seventy-two patients were randomly assigned to two groups: standard dissection and limited dissection. Postoperative pain and inflammatory response were compared between groups.

Results

The groups were well matched except for subcutaneous dissection area (137.11 ± 21.10 vs. 83.69 ± 12.10 cm², p < 0.0001). No significant difference was found with regard to VAS score and postoperative inflammatory response.

Conclusion

Our RCT indicated that the subcutaneous area plays a less important role with regard to BAET-related postoperative pain.

     

Comparison of postoperative early and late complications between pancreas-sparing duodenectomy and pancreatoduodenectomy

Purpose

Pancreas-sparing duodenectomy (PSD) represents an alternative procedure to pancreatoduodenectomy (PD) for patients with duodenal neoplasms.

Methods

The postoperative early and late complications of 21 patients who underwent PSD between 1992 and 2014 were compared with those of 44 patients with soft pancreatic parenchyma who underwent PD between 2009 and 2014.

Results

The median operation time and blood loss were less in the PSD group than in the PD group (P < 0.001). The overall incidence of early complications was less in the PSD group than in the PD group (PSD with ampullectomy vs. PSD without ampullectomy vs. PD; 45.5 vs. 20.0 vs. 56.8 %). The incidence of pancreatic fistula formation and overall incidence of late complications were also less in the PSD group than in the PD group (P = 0.031, 0.020). There were no complications related to the pancreatic endocrine or exocrine functions in the PSD group.

Conclusion

PSD is a less-invasive procedure and has the advantage over PD of preserving the pancreas.

     

Ranula: Current Concept of Pathophysiologic Basis and Surgical Management Options

Background

There is no consensus opinion on a definitive surgical management option for ranulas to curtail recurrence, largely from the existing gap in knowledge on the pathophysiologic basis.

Aim

To highlight the current scientific basis of ranula development that informed the preferred surgical approach.

Design

Retrospective cohort study.

Setting

Public Tertiary Academic Health Institution.

Method

A 7-year 7-month study of ranulas surgically managed at our tertiary health institution was undertaken—June 1, 2008–December 31, 2015—from case files retrieved utilising the ICD-10 version 10 standard codes.

Results

Twelve cases, representing 0.4 and 1.2% of all institutional and ENT operations, respectively, were managed for ranulas with a M:F = 1:1. The ages ranged from 5/12 to 39 years, mean = 18.5 years, and the disease was prevalent in the third decade of life. Main presentation in the under-fives was related to airway and feeding compromise, while in adults, cosmetic facial appearance. Ranulas in adults were plunging (n = 8, 58.3%), left-sided save one with M:F = 2:1. All were unilateral with R:L = 1:2. Treatment included aspiration (n = 2, 16.7%) with 100% recurrence, intra-/extraoral excision of ranula only (n = 4, 33.3%) with recurrence rate of 50% (n = 2, 16.7%), while marsupialisation in children (n = 1, 8.3%) had no recurrence. Similarly, transcervical approach (n = 5, 41.7%) with excision of both the ranula/sublingual salivary gland recorded zero recurrence. Recurrence was the main complication (n = 4, 33.3%).

Conclusion

With the current knowledge on the pathophysiologic basis, extirpation of both the sublingual salivary gland and the ranula by a specialist surgeon is key for a successful outcome.

     

Outcomes of Bariatric Surgery in Patients with Inflammatory Bowel Disease

Background

Obesity has become prevalent in patients with inflammatory bowel disease (IBD). Bariatric surgery can be considered to be contraindicated in IBD patients. We aimed to evaluate feasibility, safety, and efficacy of bariatric surgery in IBD patients.

Methods

We retrospectively identified all morbidly obese patients with a known diagnosis of IBD, who underwent bariatric surgery between January 2005 and December 2012. Postoperative outcomes and status of IBD in patients on maintenance therapy for their disease were assessed.

Results

We identified 20 IBD patients including 13 ulcerative colitis (UC) and 7 Crohn’s disease (CD) patients with a mean age of 54.0?±?10.5 years, BMI of 50.1?±?9.0 kg/m², and duration of IBD of 11.3?±?5.2 years. Eleven patients were on medication for IBD at baseline. Bariatric procedures included sleeve gastrectomy (N?=?9), gastric bypass (N?=?7), gastric banding (N?=?3), and one conversion of band to gastric bypass. There were no intraoperative complications, but two conversions to laparotomy due to adhesions. Mean BMI change and excess weight loss at 1 year was 14.3?±?5.7 kg/m² and 58.9?±?21.1 %, respectively. Seven early postoperative complications occurred including dehydration (N?=?5), pulmonary embolism (N?=?1), and wound infection (N?=?1). During a mean follow-up of 34.6?±?21.7 months, five patients developed complications including pancreatitis (N?=?2), ventral hernia (N?=?2), and marginal ulcer (N?=?1). Nine out of ten eligible patients experienced improvement in their IBD status.

Conclusions

Bariatric surgery is feasible and safe in morbidly obese patients suffering from IBD. In addition to being an effective weight loss procedure, bariatric surgery may help mitigate symptoms in this patient population.

     

Does Diverting Loop Ileostomy Improve Outcomes Following Open Ileo-Colic Anastomoses? A Nationwide Analysis

Background

Anastomotic leak is one of the most feared complications of gastrointestinal surgery. Surgeons routinely perform a diverting loop ileostomy (DLI) to protect high-risk colo-rectal anastomoses.

Study Design

The NSQIP database was queried from 2012 to 2013 for patients undergoing open ileo-colic resection with and without a DLI. The primary outcome was the development of any anastomotic leak—including those managed operatively and non-operatively. Secondary outcomes included overall complication rate, return to the OR, readmission, and 30-day mortality.

Results

Four thousand one hundred fifty-nine patients underwent open ileo-colic resection during the study period. One hundred eighty-six (4.5 %) underwent a DLI. Factors associated with the addition of a DLI included emergency surgery, pre-operative sepsis, and IBD. There were 197 anastomotic leaks (4.7 %) with 100 patients requiring reoperation (2.4 %). DLI was associated with a decrease in anastomotic leaks requiring reoperation (DLI vs no DLI: 0 (0 %) vs 100 (2.5 %); p?=?0.02) and with increased readmission (OR 1.93; 95 % CI 1.30–2.85; p?=?0.001).

Conclusion

DLI is rarely used for open ileo-colic resection. There were no serious leaks requiring reoperation in the DLI group. A DLI was associated with an almost two-fold increase in the odds of readmission. Surgeons must weigh the reduction in serious leak rate with postoperative morbidity when considering a DLI for open ileo-colic resection.

     

Arthroscopic popliteus bypass graft for posterolateral instabilities of the knee

Objective

An arthroscopic technique for the reconstruction of the posterolateral corner combined with posterior cruciate ligament (PCL) reconstruction was developed.

Indications

Posterolateral rotational instabilities of the knee. Combined lesions of the PCL, the popliteus complex (PLT) and the posterolateral corner. Isolated PLT lesions lacking static stabilizing function.

Contraindications

Neuromuscular disorders; knee deformities or fractures; severe posterolateral soft tissue damage.

Surgical technique

Six arthroscopic portals are necessary. Using the posteromedial portal, resect dorsal septum with a shaver. Visualize the PCL, the lateral femoral condyle and the posterolateral recessus with the PLT. Dissect the popliteomeniscal fibers; retract PLT until sulcus popliteus is visualized. Drill a 6-mm tunnel anteriorly into the distal third of the sulcus popliteus. Visualize femoral footprint of the PLT and place an anatomical drill tunnel. Pull the popliteus bypass graft into the knee and fix with bioscrews. Fix the reconstructed PCL. In cases of additional LCL injury, reconstruct LCL with autologous graft.

Postoperative management

Partial weight-bearing for 6 weeks, range of motion exercises, quadriceps-strengthening exercises on postoperative day 1. Full extension allowed immediately with flexion limited to 20° for 2 weeks, to 45° for up to week 4, and to 60° up to week 6. Use a PCL brace for 3 months, running and squatting exercises allowed after 3 months.

Results

In the 35 patients treated, no technique-related complications. After 1 year, 12 patients had a mean Lysholm Score of 88.6 (± 8.7) points and a side-to-side difference in the posterior drawer test of 2.9 (± 2.2) mm (preoperative 13.3 [± 1.9] mm).

Conclusion

Low complication risk and good and excellent clinical results after arthroscopic posterolateral corner reconstruction.

     

A simplified surgical technique for recurrent inguinal hernia repair following total extraperitoneal patch plastic

Purpose

To present a new and alternative method for surgical treatment of recurrent inguinal hernia after total extraperitoneal patch plastic (TEP).

Methods

From January 2005 to September 2015, 35 patients (34 male, 1 female; mean age 65 ± 12.6 years) with recurrent inguinal hernia following TEP were operated at the Kliniken Essen-Mitte using a simplified method consisting of re-fixation of the primary mesh to the inguinal ligament by an anterior approach.

Results

The mean operating time was 47 ± 22 min. All complications were minor with an overall incidence of 6%. After a mean follow-up of 54 months one re-recurrence was observed.

Conclusions

This Simplified Hernia Repair is safe and avoids additional foreign body implantation. Therefore, it is our method of choice for recurrent inguinal hernias after TEP.
