The use of laparoscopic subtotal cholecystectomy for complicated cholelithiasis. Surg Endosc. 2008;22:1697-1700. [PMID: 18071804 DOI: 10.1007/s00464-007-9699-5]

Laparoscopic subtotal cholecystectomy for the difficult gallbladder: Evolution of technique at a single teaching hospital

BACKGROUND

We have developed an algorithmic approach to laparoscopic cholecystectomy, including subtotal cholecystectomy, as a bailout strategy when the Critical View of Safety cannot be safely achieved due to significant inflammation and fibrosis of the hepatocystic triangle.

METHODS

This is a retrospective cohort study comparing postoperative outcomes in patients with severe cholecystitis who underwent laparoscopic cholecystectomy or laparoscopic subtotal cholecystectomy at St. Joseph's Health Centre from May 2016 to July 2021, as well as against a historical cohort. We further stratified laparoscopic subtotal cholecystectomy cases based on fenestrating or reconstituting subtype.

RESULTS

The cohort included a total of 105 patients who underwent laparoscopic cholecystectomy and 31 patients who underwent laparoscopic subtotal cholecystectomy. Bile leaks (25.8% vs 1.0%, relative risk 3.5, 95% confidence interval 3.5-208.4) were more common in the laparoscopic subtotal cholecystectomy group. Postoperative endoscopic retrograde cholangiopancreatography (22.6% vs 3.8%, relative risk 5.9, 95% confidence interval 1.9-18.9) and biliary stent insertion (19.4% vs 1.0%, relative risk 20.3, 95% confidence interval 2.5-162.5) were also more common in the laparoscopic subtotal cholecystectomy group. Bile leaks in laparoscopic subtotal cholecystectomy were only documented in the fenestration subtype, most of which were successfully managed with endoscopic retrograde cholangiopancreatography and biliary stenting. Compared to our previous study of laparoscopic cholecystectomy and subtotal cholecystectomy for severe cholecystitis between 2010 and 2016, there has been a decrease in postoperative laparoscopic cholecystectomy complications, subtotal cholecystectomy cases, and no bile duct injuries.

CONCLUSION

Following our algorithmic approach to safe laparoscopic cholecystectomy has helped to prevent bile duct injury. Laparoscopic cholecystectomy remains the gold standard for the management of severe cholecystitis; however, in extreme cases, laparoscopic subtotal cholecystectomy is a safe bailout strategy with manageable morbidity.

A systematic review on laparoscopic subtotal cholecystectomy for difficult gallbladders: a lifesaving bailout or an incomplete operation?

INTRODUCTION

Laparoscopic subtotal cholecystectomy (LSTC) is a bailout procedure that is undertaken when it is not safe to proceed with a laparoscopic total cholecystectomy owing to dense adhesions in Calot's triangle. The main aim of this review was to investigate the early (≤30 days) and late (>30 days) morbidity and mortality of LSTC.

METHODS

A literature search of the PubMed® (MEDLINE®), Google Scholar™ and Embase® databases was conducted to identify all studies on LSTC published between 1985 and December 2020. A systematic review was then performed.

RESULTS

Overall, 45 studies involving 2,166 subtotal cholecystectomy patients (51% female) were identified for inclusion in the review. The mean patient age was 55 years (standard deviation: 15 years). Just over half (53%) of the patients had an elective procedure. The conversion rate was 6.2% (n=135). The most common indication was acute cholecystitis (49%). Different techniques were used, with the majority having a closed cystic duct/gallbladder stump (71%). The most common closure technique was intracorporeal suturing (53%), followed by endoloop closure (15%). Four patients (0.18%) died within thirty days of surgery. Morbidity within 30 days included bile duct injury (0.23%), bile leak (18%) and intra-abdominal collection (4%). Reoperation was reported in 23 patients (1.2%), most commonly for unresolving intra-abdominal collections and failed endoscopic retrograde cholangiopancreatography to control bile leak. Long-term follow-up was reported in 30 studies, the median follow-up duration being 22 months. Late morbidity included incisional hernias (6%), symptomatic gallstones (4%) and common bile duct stones (2%), with 2% of cases requiring completion of cholecystectomy.

CONCLUSIONS

LSTC is an acceptable alternative in patients with a "difficult" Calot's triangle.

Indications and Outcomes of Completion Cholecystectomy: A 5-year Experience From a Rural Tertiary Center

BACKGROUND

Completion cholecystectomy (CC) is performed for recurrent or persistent biliary symptoms following subtotal cholecystectomy (STC) or incomplete cholecystectomy (IC). Due to its complexity, cases are often referred to hepato-pancreato-biliary (HBP) surgeons. There is little published literature on indications or outcomes of CC.

METHODS

Completion cholecystectomy cases performed between 2016 and 2021 by the sole HPB surgeon covering a rural referral base of >250-mile radius in West Texas were included. Primary variables of interest include indications and outcomes of CC.

RESULTS

Of the eleven patients included, 5 (45.5%) had laparoscopic STC, 3 patients (27.3%) had laparoscopic converted to open STC, and 2 (18.2%) had laparoscopic IC. Most STC cases (6/9, 66.6%) were reconstituting, while 3 STC cases were fenestrating (all had persistent bile leak). For reconstituting STC, indications were symptomatic cholelithiasis in 5 patients (45.5%), and choledocholithiasis in 3 patients (27.3%). The median (IQR) duration between index procedure and subsequent CC was 15 (1.4-92) months. The median (IQR) remnant gallbladder length was 4 (3-4.5) cm. Completion cholecystectomy was performed robotically in 8 cases (72.7%). Post-CC complications occurred in 3 patients (27.3%); these were 1 superficial surgical site infection, 1 hepatic abscess requiring percutaneous drainage, and lastly atrial fibrillation.

CONCLUSIONS

All patients requiring CC had residual gallbladder remnant >2.5 cm; this is longer than recommended for STC. Completion cholecystectomy is a complex operation that carries significant morbidity, even when performed using minimally invasive techniques. As bailout procedures become more common in severely inflamed cholecystitis, it is important to collate more data on the outcomes of requiring CC.

Review of the Literature on Partial Resections of the Gallbladder, 1898-2022: The Outline of the Conception of Subtotal Cholecystectomy and a Suggestion to Use the Terms 'Subtotal Open-Tract Cholecystectomy' and 'Subtotal Closed-Tract Cholecystectomy'

Current descriptions of the history of subtotal cholecystectomy require more details and accuracy. This study presented a narrative review of the articles on partial resections of the gallbladder published between 1898 and 2022. The Scale for the Assessment of Narrative Review Articles items guided the style and content of this paper. The systematic literature search yielded 165 publications. Of them, 27 were published between 1898 and 1984. The evolution of the partial resections of the gallbladder began in the last decade of the 19th century when Kehr and Mayo performed them. The technique of partial resection of the gallbladder leaving the hepatic wall in situ was well known in the 3rd and 4th decades of the 20th century. In 1931, Estes emphasised the term 'partial cholecystectomy'. In 1947, Morse and Barb introduced the term 'subtotal cholecystectomy'. Madding and Farrow popularised it in 1955-1959. Bornman and Terblanche revitalised it in 1985. This term became dominant in 2014. From a subtotal cholecystectomy technical execution perspective, it is either a single-stage (when it includes only the resectional component) or two-stage (when it also entails closure of the remnant of the gallbladder or cystic duct) operation. Recent papers on classifications of partial resections of the gallbladder indicate the extent of gallbladder resection. Subtotal cholecystectomy is an umbrella term for incomplete cholecystectomies. 'Subtotal open-tract cholecystectomy' and 'subtotal closed-tract cholecystectomy' are terms that characterise the type of completion of subtotal cholecystectomy.

Thinking Your Way Through a Difficult Laparoscopic Cholecystectomy: Technique for High-Quality Subtotal Cholecystectomy

Laparoscopic subtotal cholecystectomy (LSC) is a bailout strategy to prevent bile duct injury in difficult gallbladder cases. It is associated with acceptable morbidity that is readily managed with postoperative interventions. Here we share our techniques for LSC. We begin with landmarking, which includes the line of safety, a theoretical line the sulcus of Rouvière and the junction of the cystic and hilar plates. If the fundus can be grasped, then the gallbladder is dissected off the cystic plate using the top-around approach. The gallbladder is then amputated, creating a short cuff of proximal gallbladder. This cuff can be left patent (2A) or cinched close with an ENDOLOOP (Ethicon) if it is small, ideally less than 1 cm (1A). If the fundus cannot be grasped, then an inverted T incision is made on the anterior gallbladder wall. The longitudinal incision is extended toward the fundus, and the transverse incision is extended superiorly along the cystic plate edge. Two "bunny ears" are developed and ultimately resected to excise the anterior gallbladder wall at an oblique angle while leaving the posterior wall intact (2B). If the remaining cuff is small, then it can be sutured closed against the gallbladder back wall (1B). In the setting of extensive bowel adhesion to the anterior gallbladder, we perform a fundectomy, from which we extend two incisions along the cystic plate to open the gallbladder like a clamshell. Our paper describes and illustrates our St Joseph's Health Centre institutional LSC approach and subtype classification (1A, 1B, 2A, and 2B).

Clinical outcome of subtotal cholecystectomy for difficult gallbladder

When the Calot triangle structures cannot be found and a critical evaluation of patient safety cannot be achieved, surgeons perform a subtotal cholecystectomy (SC). objective Evaluation and analysis of the outcomes of subtotal cholecystectomy at the GIT and Hepatology teaching Hospital is to be conducted. Retrospective analysis of patient data and research methodologies thirteen hundred and eighty onsecutive cholecystectomy patients at GIT & Hepatology Hospital (Oct.2017 to Apr.2020). 53 of the 1380 people investigated underwent a partial cholecystectomy. Routine laparoscopic or open cholecystectomy patients (13.27) could not be included in the study. An individual patient's medical history is mined for information on their preoperative features. Results 53 individuals had subtotal cholecystectomy, with 29 males (55.7%) and 24 women (24.8%) both undergoing the procedure (45.2 percent ). Patients in the research, who ranged in age from 20 to 69, had an average age of 43.5 years. The bulk of the 45 patients (87.2%) had elective surgery, whereas only 8 (15%) had emergency surgery. There were 33 cases of laparoscopic subtotal cholecystectomy and only 20 cases of open subtotal cholecystectomy in this study (6 patients had conversion subtotal cholecystectomy).

Occlusion of the cystic duct with cyanoacrylate glue at laparoscopic subtotal fenestrating cholecystectomy for a difficult gallbladder

BACKGROUND

Subtotal cholecystectomy is occasionally the management of choice in the patient with a hostile Calot's triangle but when it is not considered safe to close the cystic duct this often leads to a biliary fistula. In order to reduce this morbidity a novel strategy to seal the cystic duct with cyanoacrylate glue was introduced. The outcome of the two strategies have been compared.

METHODS

Patients who had a laparoscopic subtotal cholecystectomy where the cystic duct was left open, the Unsecured group, were compared with those where the duct orifice was occluded with cyanoacrylate glue, the Glued group. The outcome of the two strategies have been compared by duration of biliary drainage, whether a leak was shown on ERCP, time to removal of the drain, length of hospital stay, the re-operation and readmission rates.

RESULTS

In 78 cases of laparoscopic subtotal cholecystectomy it was considered unsafe to close the cystic duct. 36 patients were managed without closure of the cystic duct, the Unsecured group and bile drainage continued for more than 3 days in 9 cases (25%) compared with 3 of 42 cases (7%) treated with glue, the Glued group (NS). Postoperative ERCP demonstrated a leak more frequently in the Unsecured group (p < 0.02). The length of stay was reduced in the Glued group. (0.9 compared with 3.0 days, p < 0.01).

CONCLUSION

The results suggest that glue may be a safe option to occlude the cystic duct orifice and reduce hospital stay when this cannot safely be closed at subtotal cholecystectomy.

Subtotal Cholecystectomy After Failed Critical View of Safety Is an Effective and Safe Bail Out Strategy

BACKGROUND

Bile duct injury (BDI) is accompanied by significant morbidity and long-term impact in quality of life. Subtotal cholecystectomy (STC) is an alternative to prevent this outcome but is associated with other complications. The aim of this work is to demonstrate that BDI associated morbidity exceeds STC associated morbidity, underscoring STC as a reasonable bail out strategy.

METHODS

We compared 115 patients who underwent STC with 293 patients who were referred to our center with BDI type E1-E3 and underwent surgical repair. The groups were comparable because in both instances the surgeon had the opportunity to decide not to perform a total cholecystectomy once critical view of safety (CVS) was not achieved.

RESULTS

Bile leakage was found in 21% of the STC group with only one BDI (0.9%). More Accordion ≥ 4 were found in the STC group (10.4% vs 4.8%, p = 0.035); however, reoperations were more frequent in the BDI group (8.2% vs 0.9%, p = 0.006). No patient in the STC group required reintervention for completion cholecystectomy. After 3.8 years follow-up, 2.4% of patients had secondary biliary cirrhosis in the BDI group; none in the STC group.

CONCLUSIONS

Despite complications of STC, morbidity associated with BDI is much higher due to high long-term reoperation rate, in addition to secondary biliary cirrhosis. STC is a safe alternative that can prevent BDI if properly and timely performed in the context of difficult cholecystectomy.

Subtotal cholecystectomy for difficult acute cholecystitis: how to finalize safely by laparoscopy-a systematic review

Background

Aim of this study was to clarify the best laparoscopic subtotal cholecystectomy (LSTC) technique for finalizing a difficult cholecystectomy.

Patients and methods

A review was performed (1987–2021) searching "difficulty cholecystectomy" AND/OR "subtotal cholecystectomy". The LSTC techniques considered were as follows: type A, leaving posterior wall attached to the liver and the remainder of the gallbladder stump open; type B, like type A but with the stump closed; type C, resection of both the anterior and posterior gallbladder walls and the stump closed; type D, like type C but with the stump open. Morbidity (including mortality) was analysed with Dindo–Clavien classification.

Results

Nineteen articles were included. Of the 13,340 patients screened, 678 (8.2%) had cholecystectomy finalized by LSTC: 346 patients (51.0%) had type A LSTC, 134 patients (19.8%) had type B LSTC, 198 patients (29.2%) had type C LSTC, and 198 patients (0%) had type D LSTC. Bile leakage was found in 83 patients (12.2%), and recorded in 58 patients (69.9%) treated by type A. Twenty-three patients (3.4%) developed a subhepatic collection, 19 of whom (82.6%) were treated by type A. Other complications were reported in 72 patients (10.6%). The Dindo–Clavien classification was four for grade I, 27 for grade II, 126 for grade IIIa, 18 for grade IIIb, zero for grade IV and three for grade V.

Conclusion

In the case of LSTC, closure of the gallbladder stump represents the best method to avoid complications. Careful exploration of the gallbladder stump is mandatory, washing the abdominal cavity and leaving drainage.

Risks associated with subtotal cholecystectomy and the factors influencing them: A systematic review and meta-analysis of 85 studies published between 1985 and 2020

BACKGROUND

Subtotal cholecystectomy is recognized as a rescue procedure performed in grossly suboptimal circumstances that would deem a total cholecystectomy too risky to execute. An earlier systematic review based on 30 studies published between 1985 and 2013 concluded that subtotal cholecystectomy had a morbidity rate comparable to that of total cholecystectomy. This systematic review appraises 17 clinical outcomes in patients undergoing subtotal cholecystectomy.

METHODS

The study protocol was registered with the International Prospective Register for Systematic Reviews (CRD42020172808). MEDLINE, Embase, Cochrane bibliographic databases, and Google Scholar were used to identify papers published between 1985 and June 2020. Data related to the surgical setting, approach, intervention on the hepatic wall of the gallbladder, type of completion of subtotal cholecystectomy, year of study, and study design were collected. Seventeen clinical outcomes were considered. Meta-analyses were performed using a random-effects model, and the effect size was presented as risk ratios with 95% confidence intervals.

RESULTS

From 1,017 records, 85 eligible studies were identified and included. These included 3,645 patients who underwent subtotal cholecystectomy. Laparoscopic (80.1%, n = 2,918) and reconstituting (74.6%, n = 2,719) approaches represented the majority of all subtotal cholecystectomy cases. Seven (0.2%) cases of injury to the bile duct were reported. Bile leak was reported in 506 (13.9%) patients. Reconstituting subtotal cholecystectomy was associated with a lower risk for 11 clinical outcomes. Open subtotal cholecystectomy was associated with an increased rate of 30-day mortality and wound infections.

CONCLUSION

Subtotal cholecystectomy is associated with significant morbidity. Laparoscopic and reconstituting surgery may reduce the risks of some perioperative complications and long-term sequelae after subtotal cholecystectomy.

Laparoscopic subtotal cholecystectomy: comparison of reconstituting and fenestrating techniques

BACKGROUND

Laparoscopic subtotal cholecystectomy (LSC) is a safe bailout procedure in situations when dissection of "critical view of safety" is not possible. After the proposed classification of subtotal cholecystectomy into "fenestrating" and "reconstituting" techniques in 2016, a comparative review of the outcomes of both methods is timely.

METHODS

A literature search of the PubMed, Cochrane Library, and Web of Science database was conducted up to January 31, 2020 for studies that reported LSC. Studies reporting LSC only in patients with Mirizzi syndrome or xanthogranulomatous cholecystitis were excluded. Our analysis includes 39 studies with 1784 cases of LSC. We report a comparison of outcomes between reconstituting and fenestrating LSC on 1505 cases [935 reconstituting (62.1%) and 570 fenestrating (37.9%)].

RESULTS

Following LSC, the rate of open conversion is 7.7%, hemorrhage is 0.4%, bile duct injury is 0.3%, bile leak is 15.4%, retained stone is 4.6%, subhepatic or subphrenic collection is 2.9%, superficial surgical site infection is 2.0% and 30-day mortality is 0.2%. 8.8% of patients required postoperative endoscopic retrograde cholangiopancreatography (ERCP), 1.1% required percutaneous intervention, and 2.2% required reoperation. Compared to reconstituting LSC, fenestrating LSC has a higher incidence of open conversion (n = 58, 10.2% vs. n = 43, 4.6%, p < 0.001), retained stones (n = 38, 6.7% vs. n = 38, 4.1%, p = 0.0253), subhepatic or subphrenic collections (n = 33, 5.8% vs. n = 13, 1.4%, p < 0.001), superficial surgical site infections (n = 18, 3.2% vs. n = 14, 1.5%, p = 0.0303), postoperative ERCP (n = 82, 14.4% vs. n = 62, 6.6%, p < 0.001), and need for reoperation (n = 20, 3.5% vs. n = 12, 1.3%, p < 0.001).

CONCLUSIONS

Although reconstituting LSC has better outcomes, both techniques are complementary. Intraoperative findings and surgical expertise impact the choice.

Re-interventions and re-admissions in a 13-year series following use of laparoscopic subtotal cholecystectomy

Background:

Laparoscopic subtotal cholecystectomy (LSTC) without cystic duct ligation is an alternative to conversion to open surgery in a difficult cholecystectomy, thus avoiding a potentially hazardous dissection in Calot's triangle. The long-term outcomes of this procedure are not well reported. The aim of this study is to assess the rates of re-presentation, re-admissions, endoscopic interventions and completion cholecystectomy in patients who have undergone LSTC.

Methods:

Details of all patients undergoing cholecystectomy over a 13-year period (2003–2015) were entered on a prospective database. Further information on subsequent hospital attendances, biliary imaging, endoscopic interventions and re-operations following the index LSTC was collected retrospectively from hospital database.

Results:

Overall, 2313 patients underwent laparoscopic cholecystectomy. Eighty-five patients (3.7%) underwent LSTC and the rest had standard laparoscopic cholecystectomy. A controlled bile leak was observed in 16 (19%) patients post-operatively, of which 3 resolved spontaneously. The remaining 13 were managed with an early endoscopic retrograde cholangiopancreatography (ERCP) and biliary stent. Twenty-seven patients (32%), who underwent LSTC, were re-investigated for the upper abdominal symptoms. The time range for re-investigation was 21 days–124 months. Eight patients underwent ERCP post-discharge, for suspected bile duct stones on radiological imaging. Two patients required open completion cholecystectomy for symptomatic stones in the gallbladder remnant.

Conclusion:

LSTC is a feasible and safe alternative to open surgery with acceptable long-term consequences and re-interventions.

Is subtotal cholecystectomy safe and feasible? Short- and long-term results

BACKGROUND

Cholecystectomy is one of the most commonly performed surgical procedures. However, it may result in some unpleasant conditions such as bile duct injury (BDI), bile leak, and vessel injury. Subtotal cholecystectomy (SC), which has been introduced as an alternative method for reducing the complication rates, has been reported to have lower risk of BDI when compared to total cholecystectomy. This study aimed to evaluate the indications for SC, its early and late complications and their management, and the risk factors affecting the bile leak.

METHODS

Fifty-seven patients who underwent SC were included in the study, and their medical records were retrospectively reviewed.

RESULTS

Thirty-three patients were male (57.9%) and the mean age was 64.84 ± 11.35 (range: 29-86). All patients had at least one episode of cholecystitis. Forty-seven (82.5%) patients underwent surgery under emergency conditions. Postoperative bile leak/fistula, surgical site infection, and fluid collection were developed in 12 (21.1%), eight (14%), and six (10.5%) patients, respectively. Leaving the remnant tissue pouch open, presence of comorbidity and emergency operative condition were found to increase the risk of leak development (P < .001). During the average follow-up of 49 months (range: 13-98), symptomatic choledocholithiasis, symptomatic gallstones in the remnant tissue, and incisional hernia were detected within the first year of surgery in three (5.3%), four (7%), and seven (12.3%) patients, respectively.

CONCLUSIONS

Although SC is not an equivalent to total cholecystectomy, its vital benefit of lowering the risk of BDI should be considered in difficult cases.

Factors related to residual gallbladder calculi formation using computed tomography and magnetic resonance imaging combined with clinical data

Objective

We aimed to investigate risk factors related to remnant gallbladder (RGB) stones.

Methods

This retrospective study included 73 patients with RGB, in groups with and without RGB calculi. Univariate analyses were used to identify nine variables associated with RGB calculi: sex, age, body mass index (BMI), time to detection, surgical method, length of RGB, angle of RGB and common hepatic duct (CHD), choledocholithiasis, and remnant cholecystitis. Multivariate logistic regression was performed to assess independent predictors of RGB stones. A receiver operating characteristic (ROC) curve was used to estimate model accuracy and determine cut-off values of independent predictors.

Results

We enrolled 73 patients, 33 with and 40 without RGB stones. Univariate analyses showed that age, BMI, time to detection, length of RGB, angle of RGB and CHD were predictors for RGB calculi. Multivariate analyses indicated that time to detection, length of RGB, and angle of RGB and CHD were independent predictors for RGB calculi. The area under the ROC curve of the model was 0.940. Cut-off values of the three indicators were 1.5 years, 2.25 cm, and 22.5°, respectively.

Conclusion

Time to detection, length of RGB, and angle of RGB and CHD were independent predictors of RGB calculi.

Safe Cholecystectomy Multi-society Practice Guideline and State of the Art Consensus Conference on Prevention of Bile Duct Injury During Cholecystectomy

BACKGROUND

BDI is the most common serious complication of laparoscopic cholecystectomy. To address this problem, a multi-society consensus conference was held to develop evidenced-based recommendations for safe cholecystectomy and prevention of BDI.

METHODS

Literature reviews were conducted for 18 key questions across 6 broad topics around cholecystectomy directed by a steering group and subject experts from 5 surgical societies (Society of Gastrointestinal and Endoscopic Surgeons, Americas Hepato-Pancreato-Biliary Association, International Hepato-Pancreato-Biliary Association, Society for Surgery of the Alimentary Tract, and European Association for Endoscopic Surgery). Evidence-based recommendations were formulated using the grading of recommendations assessment, development, and evaluation methodology. When evidence-based recommendations could not be made, expert opinion was documented. A number of recommendations for future research were also documented. Recommendations were presented at a consensus meeting in October 2018 and were voted on by an international panel of 25 experts with greater than 80% agreement considered consensus.

RESULTS

Consensus was reached on 17 of 18 questions by the guideline development group and expert panel with high concordance from audience participation. Most recommendations were conditional due to low certainty of evidence. Strong recommendations were made for (1) use of intraoperative biliary imaging for uncertainty of anatomy or suspicion of biliary injury; and (2) referral of patients with confirmed or suspected BDI to an experienced surgeon/multispecialty hepatobiliary team.

CONCLUSIONS

These consensus recommendations should provide guidance to surgeons, training programs, hospitals, and professional societies for strategies that have the potential to reduce BDIs and positively impact patient outcomes. Development of clinical and educational research initiatives based on these recommendations may drive further improvement in the quality of surgical care for patients undergoing cholecystectomy.

Safe laparoscopic cholecystectomy: A systematic review of bile duct injury prevention

BACKGROUND

Since the introduction of laparoscopic cholecystectomy (LC), a substantial increase in bile duct injury (BDI) incidence was noted. Multiple methods to prevent this complication have been developed and investigated. The most suitable method however is subject to debate. In this systematic review, the different modalities to aid in the safe performance of LC and prevent BDI are delineated.

MATERIALS AND METHODS

A systematic search for articles describing methods for the prevention of BDI in LC was conducted using EMBASE, Medline, Web of science, Cochrane CENTRAL and Google scholar databases from inception to 11 June 2018.

RESULTS

90 studies were included in this systematic review. Overall, BDI preventive techniques can be categorized as dedicated surgical approaches (Critical View of Safety (CVS), fundus first, partial laparoscopic cholecystectomy), supporting imaging techniques (intraoperative radiologic cholangiography, intraoperative ultrasonography, fluorescence imaging) and others. Dedicated surgical approaches demonstrate promising results, yet limited research is provided. Intraoperative radiologic cholangiography and ultrasonography demonstrate beneficial effects in BDI prevention, however the available evidence is low. Fluorescence imaging is in its infancy, yet this technique is demonstrated to be feasible and larger trials are in preparation.

CONCLUSION

Given the low sample sizes and suboptimal study designs of the studies available, it is not possible to recommend a preferred method to prevent BDI. Surgeons should primarily focus on proper dissection techniques, of which CVS is most suitable. Additionally, recognition of hazardous circumstances and knowledge of alternative techniques is critical to complete surgery with minimal risk of injury to the patient.

Management of residual gall bladder: A 15-year experience from a north Indian tertiary care centre

Backgrounds/Aims

A residual gallbladder (RGB) following a partial/subtotal cholecystectomy may cause symptoms that require its removal. We present our large study regarding the problem of a RGB over a 15 year period.

Methods

This study involved a retrospective analysis of patients managed for symptomatic RGB from January 2000 to December 2015.

Results

A RGB was observed in 93 patients, who had a median age of 45 (25-70) years, and were comprised of 69 (74.2%) females. The most common presentation was recurrence pain (n=64, 68.8%). Associated choledocholithiasis was present in 23 patients (24.7%). An ultrasonography (USG) failed to diagnose RGB calculi in 10 (11%) patients; whereas, magnetic resonance cholangio-pancreatography (MRCP) accurately diagnosed RGB calculi in all the cases except for 2 (4%) and, additionally, detected common bile duct (CBD) stones in 12 patients. Completion cholecystectomy was performed in all patients (open 45 [48.4%]; laparoscopic 48 [51.6%] and 19 [20.4%] patients required a conversion to open). The RGB pathology included stones in 90 (96.8%), Mirizzi's syndrome in 10 (10.8%) and an internal fistula in 9 (9.7%) patients. Additional procedures included CBD exploration (n=6); Choledocho-duodenostomy (n=4) and Roux-en-Y hepatico-jejunostomy (n=3). The mortality and morbidity were nil and 11% (all wound infection), respectively. Two patients developed incisional hernia during follow up. The mean follow up duration was 23.1 months (3-108) in 65 patients and the outcome was excellent and good in 97% of the patients.

Conclusions

Post-cholecystectomy recurrent biliary colic should raise suspicion of RGB. MRCP is a useful investigation for the diagnosis and assessment of any associated problems and provides a roadmap for surgery. Laparoscopic completion cholecystectomy is feasible, but is technically difficult and has a high conversion rate.

Laparoscopic subtotal cholecystectomy: a surgical alternative to reduce complications in complex cases

INTRODUCTION

Laparoscopic cholecystectomy is a common procedure in general surgery, and in complex cases it is important for the surgeon to know all the alternatives with low associated morbidity. Laparoscopic subtotal cholecystectomy should be considered as an option when a critical view of safety cannot be obtained, because it has a low complication rate and gives the advantages of minimally invasive surgery.

METHODS

Retrospective study of laparoscopic subtotal cholecystectomies in an eight years period.

RESULTS

A total of 1,059 laparoscopic cholecystectomies were performed; 22 were subtotal cholecystectomies, without conversion. Biliary fistula (9%) and intraabdominal collections (4.5%) were the most common complications described. No iatrogenic bile duct injuries or deaths were reported. Our follow-up period was 32months, no recurrences were reported.

CONCLUSIONS

Laparoscopic subtotal cholecystectomy is a safe and effective procedure. It should be considered as an option in complex cases.

Subtotal cholecystectomy for the hostile gallbladder: failure to control the cystic duct results in significant morbidity

BACKGROUND

Outcomes following the inability to control the cystic duct due to a hostile triangle of Calot during cholecystectomy remain unknown. The purpose of this study was to analyze the safety and efficacy of subtotal cholecystectomy, with attention to the necessity for secondary interventions.

METHODS

Sixteen thousand five hundred ninety six cholecystectomies from January 2002 to August 2014 were reviewed, identifying patients managed with subtotal cholecystectomy, defined as the inability to isolate/transect the cystic duct. After propensity matching, we investigated surgical indications, perioperative outcomes, and the necessity for secondary ERCP, percutaneous drainage, and completion cholecystectomy.

RESULTS

65 (0.39%) patients underwent subtotal cholecystectomy; 54 (83.1%) began laparoscopically, of which 30 (55.6%) required conversion to laparotomy. Subtotal cholecystectomy, performed more frequently for acute cholecystitis (70.8% vs 34.6%), was associated with extended hospitalizations (4 d vs 2 d) and frequent surgical site infections (20% vs 4.6%). 25 (38.5%) subtotal cholecystectomy patients required ≥1 secondary intervention, and compared to standard cholecystectomy, underwent higher rates postoperative ERCP (30.8% vs 5.4%), percutaneous drainage (9.2% vs 1.5%), and completion cholecystectomy (6.2% vs 0%) [all P < 0.05].

DISCUSSION

Subtotal cholecystectomy fails to control the cystic duct, resulting in significant morbidity. Most do not require completion cholecystectomy; however, patients demand close observation and, frequently, secondary interventions.

Clinical outcomes of subtotal cholecystectomy performed for difficult cholecystectomy

Purpose

Laparoscopic subtotal cholecystectomy (LSC) can be an alternative surgical technique for difficult cholecystectomies. Surgeons performing LSC sometimes leave the posterior wall of the gallbladder (GB) to shorten the operation time and avoid liver injury. However, leaving the inflamed posterior GB wall is a major concern. In this study, we evaluated the clinical outcomes of standard laparoscopic cholecystectomy (SLC), LSC, and LSC removing only anterior wall of the GB (LSCA).

Methods

We retrospectively reviewed the medical records of laparoscopic cholecystectomies performed between January 2006 to December 2015 and analyzed the outcomes of SLC, LSC, and LSCA.

Results

A total of 1,037 patients underwent SLC. 22 patients underwent LSC; and 27 patients underwent LSCA. The mean operating times of SLC, LSC, and LSCA were 41, 74, and 68 minutes, respectively (P < 0.01). Blood loss was 5, 45, and 33 mL (P < 0.05). The mean lengths of postoperative hospitalization were 3.4, 5.4, and 5.8 days. Complications occurred in 24 SLC patients (2.3%), 2 LSC patients (9%), and 1 LSCA patient (3.7%). There was no mortality among the LSC and LSCA patients.

Conclusion

LSC and LSCA are safe and feasible alternatives for difficult cholecystectomies. These procedures help surgeons avoid bile duct injury and conversion to laparotomy. LSCA has the benefits of shorter operation time and less bleeding compared to LSC.

The Laparoscopic Re-Exploration in the Management of the Gallbladder Remnant and the Cystic Duct Stump Calculi

INTRODUCTION

The gallbladder remnant and the cystic duct stump calculi are uncommon causes of post-cholecystectomy syndrome. Re-exploration is usually needed in the cases where symptom persists. Very few case series and reports are available regarding laparoscopic re-exploration.

AIM

To assess the safety and feasibility of Laparoscopic re-exploration in the cases of gallbladder remnant and cystic duct stump calculi leading to post cholecystectomy syndromes.

MATERIALS AND METHODS

In this study, laparoscopic re-explorations was done in 22 patients in which 17 patients had gallbladder remnant calculi and 5 had cystic duct stump calculi. The study considered parameters like the operative time, conversion rate, post-operative complications, post-operative hospital stay and mortality in these patients. The duration of study was 15 years and the data was retrospectively reviewed.

RESULTS

The median operating time was 83 minutes (range 51 to 134 minutes). Only one patient had conversion to open surgery. In postoperative period two patients had bile leak. They were managed conservatively and leak subsided in 8 and 11 days respectively. One patient had postoperative bleeding not requiring blood transfusion. There was no major complication requiring further intervention and no mortality. Patients were discharged on median day 4 (range 2-11) after the surgery. Patients were followed up every 3 months for one year. However, out of these three patients did not turn up for follow-up.

CONCLUSION

In expert hands laparoscopic re-exploration of the gallbladder remnant/cystic duct stump calculi can be performed within a reasonable operating time. The conversion to conventional re-exploration rate was very low with minimal post-operative complications and shorter hospital stay.

Laparoscopic modified subtotal cholecystectomy for difficult gall bladders: A single-centre experience

AIM:

Laparoscopic cholecystectomy (LC) is considered the ‘gold standard’ intervention for gall bladder (GB) diseases. However, to avoid serious biliovascular injury, conversion is advocated for distorted anatomy at the Calot's triangle. The aim is to find out whether our technique of laparoscopic modified subtotal cholecystectomy (LMSC) is suitable, with an acceptable morbidity and outcome.

PATIENTS AND METHODS:

A retrospective analysis of prospectively collected data of 993 consecutive patients who underwent cholecystectomy was done at a large District General Hospital (DGH) between August 2007 and January 2015. The data are as follows: Patient's demographics, operative details including intra- and postoperative complications, postoperative stay including follow-up that was recorded and analysed.

RESULTS:

A total of 993 patients (263 males and 730 female) were included. The median age was 52*(18-89) years. Out of the 993 patients, 979 (98.5%) and 14 (1.5%) were listed for laparoscopic and open cholecystectomy, respectively. Of the 979 patients, 902 (92%) and 64 (6.5%) patients underwent LC ± on-table cholangiography (OTC) and LMSC ± OTC, respectively, with a median stay of 1* (0-15) days. Of the 64 patients, 55 (86%) had dense adhesions, 22 (34%) had acute inflammation, 19 (30%) had severe contraction, 12 (19%) had empyema, 7 (11%) had Mirizzi's syndrome and 2 (3%) had gangrenous GB. The mean operative time was 120 × (50-180) min [Table 1]. Six (12%) patients required endoscopic retrograde cholangiopancreatography (ERCP) postoperatively, and there were four (6%) readmissions in a follow-up of 30 × (8-76) months. The remaining 13 (1.3%) patients underwent laparoscopic cholecystectomy converted to an open cholecystectomy. The median stay for open/laparoscopic cholecystectomy converted to open cholecystectomy was 5 × (1-12) days.

CONCLUSION:

Our technique of LMSC avoided conversion in 6.5% patients and believe that it is feasible and safe for difficult GBs with a positive outcome.

Laparoscopic Treatment of Type III Mirizzi Syndrome by T-Tube Drainage

Mirizzi syndrome (MS) is an impacted stone in the cystic duct or Hartmann's pouch that mechanically obstructs the common bile duct. We would like to report laparoscopic treatment of type III MS. A 75-year-old man was admitted with the complaint of abdominal pain and jaundice. The patient was accepted as MS type III according to radiological imaging and intraoperative view. Laparoscopic subtotal cholecystectomy, extraction of impacted stone by opening anterior surface of dilated cystic duct and choledochus, and repair of this opening by using the remaining part of gallbladder over the T-tube drainage were performed in a patient with type III MS. Application of reinforcement suture over stump was done in light of the checking with oliclinomel N4 injection trough the T-tube. At the 18-month follow-up, he was symptom-free with normal liver function tests.

Laparoscopic partial cholecystectomy: A safe and effective alternative surgical technique in "difficult cholecystectomies"

OBJECTIVE

Laparoscopic cholecystectomy has become the "gold standard" for benign gallbladder diseases due to its advantages. In the presence of inflammation or fibrosis, the risk of bleeding and bile duct injury is increased during dissection. Laparoscopic partial cholecystectomy (LPC) is a feasible and safe method to prevent bile duct injuries and decrease the conversion (to open cholecystectomy) rates in difficult cholecystectomies where anatomical structures could not be demonstrated clearly.

MATERIAL AND METHODS

The feasibility, efficiency, and safety of LPC were investigated. The data of 80 patients with cholelithiasis who underwent LPC (n=40) and conversion cholecystectomy (CC) (n=40) were retrospectively examined. Demographic characteristics, ASA scores, operating time, drain usage, requirement for intensive care, postoperative length of hospital stay, surgical site infection, antibiotic requirement and complication rates were compared.

RESULTS

The median ASA value was 1 in the CC group and 2 in the LPC group. Mean operation time was 123 minutes in the CC group, and 87.50 minutes in the LPC group. Surgical drains were used in 16 CC patients and 4 LPC patients. There was no significant difference between groups in postoperative length of intensive care unit stay (p=0.241). When surgical site infections were compared, the difference was at the limit of statistical significance (p=0.055). Early complication rates were not different (p=0.608) but none of the patients in the LPC group suffered from late complications.

CONCLUSION

LPC is an efficient and safe way to decrease the conversion rate. LPC seems to be an alternative procedure to CC with advantages of shorter operating time, lower rates of surgical site infection, shorter postoperative hospitalization and fewer complications in high-risk patients.

Laparoscopic Resection of Cholecystocolic Fistula and Subtotal Cholecystectomy by Tri-Staple in a Type V Mirizzi Syndrome

The Mirizzi syndrome (MS) is an impacted stone in the cystic duct or Hartmann's pouch that mechanically obstructs the common bile duct (CBD). We would like to report laparoscopic subtotal cholecystectomy (SC) and resection of cholecystocolic fistula by the help of Tri-Staple™ in a case with type V MS and cholecystocolic fistula, for first time in the literature. A 24-year-old man was admitted to emergency department with the complaint of abdominal pain, intermittent fever, jaundice, and diarrhea. Two months ago with the same complaint, ERCP was performed. Laparoscopic resection of cholecystocolic fistula and subtotal cholecystectomy were performed by the help of Tri-Staple. At the eight-month follow-up, he was symptom-free with normal liver function tests. In a patient with type V MS and cholecystocolic fistula, laparoscopic resection of cholecystocolic fistula and SC can be performed by using Tri-Staple safely.

Residual gallbladder stones after cholecystectomy: A literature review

BACKGROUND

Incomplete gallbladder removal following open and laparoscopic techniques leads to residual gallbladder stones. The commonest presentation is abdominal pain, dyspepsia and jaundice. We reviewed the literature to report diagnostic modalities, management options and outcomes in patients with residual gallbladder stones after cholecystectomy.

MATERIALS AND METHODS

Medline, Google and Cochrane library between 1993 and 2013 were reviewed using search terms residual gallstones, post-cholecystectomy syndrome, retained gallbladder stones, gallbladder remnant, cystic duct remnant and subtotal cholecystectomy. Bibliographical references from selected articles were also analyzed. The parameters that were assessed include demographics, time of detection, clinical presentation, mode of diagnosis, nature of intervention, site of stone, surgical findings, procedure performed, complete stone clearance, sequelae and follow-up.

RESULTS

Out of 83 articles that were retrieved between 1993 and 2013, 22 met the inclusion criteria. In most series, primary diagnosis was established by ultrasound/computed tomography scan. Localization of calculi and delineation of biliary tract was performed using magnetic resonance imaging/magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography. In few series, diagnosis was established by endoscopic ultrasound, intraoperative cholangiogram and percutaneous transhepatic cholangiography. Laparoscopic surgery, endoscopic techniques and open surgery were the most common treatment modalities. The most common sites of residual gallstones were gallbladder remnant, cystic duct remnant and common bile duct.

CONCLUSION

Residual gallbladder stones following incomplete gallbladder removal is an important sequelae after cholecystectomy. Completion cholecystectomy (open or laparoscopic) is the most common treatment modality reported in the literature for the management of residual gallbladder stones.

LigLAP: Encirclement and Ligation of Vessels in Laparoscopic Surgery: A Double-Layer Suture Sealing Approach

This article proposes a potential automatic ligation (LigLAP) method to occlude vessels and ducts in several laparoscopic surgical procedures. Currently, stapling devices are widely used for this purpose. However, there are some complications associated with stapling devices, including biliary leak and tissue damage. In this article, we examine the feasibility of an alternative method that uses a double-layer suture to encircle and occlude a vessel. A heating element melts the outer layer of the suture at the cross-point of the suture to create a seal. Several electromechanical mechanisms have been proposed to carry out this ligation process. In addition, some parts have been prototyped for experimental verification and visualization. Several double-layered sutures have been created, and their tensile strength and sealing capabilities have been measured. Moreover, a simple leakage experiment has been performed to verify experimentally the idea of using the double-layer suture. The results show that the new suture and the thermal sealing method provide the required strength to occlude balloons filled with water. Although the results suggest that the proposed method and the double-layer suture may be used in surgical ligation processes, much more rigorous testing of leakage is required.

Usefulness of laparoscopic subtotal cholecystectomy with operative cholangiography for severe cholecystitis

Purpose

Cholecystectomy can become hazardous when inflammation develops, leading to anatomical changes in Calot’s triangle. We attempted to study the safety and efficacy of laparoscopic subtotal cholecystectomy (LSC) to decrease the incidence of complications and the rate of conversion to open surgery.

Methods

Patients who underwent LSC between January 2005 and December 2008 were evaluated retrospectively. The operations were performed laparoscopically irrespective of the grade of inflammation estimated preoperatively. However, patients with severe inflammation of the gallbladder underwent LSC involving resection of the anterior wall of the gallbladder, removal of all stones and placement of an infrahepatic drainage tube. To prevent intraoperative complications, including bile duct injury, intraoperative cholangiography was performed.

Results

LSC was performed in 26 elective procedures among 26 patients (eight females, 18 males). The median patient age was 69 years (range 43–82 years). The median operative time was 125 min (range 60–215 min) and the median postoperative inpatient stay was 6 days (range 3–21 days). Cholangiography was performed during surgery in 24 patients. One patient underwent postoperative endoscopic sphincterotomy for a retained common bile duct stone that was found on cholangiography during surgery. Neither complications nor conversion to open surgery were encountered in this study.

Conclusions

LSC with the aid of intraoperative cholangiography is a safe and effective treatment for severe cholecystitis.

Mirizzi syndrome: History, current knowledge and proposal of a simplified classification

Chronic complications of symptomatic gallstone disease, such as Mirizzi syndrome, are rare in Western developed countries with an incidence of less than 1% a year. The importance and implications of this condition are related to their associated and potentially serious surgical complications such as bile duct injury, and to its modern management when encountered during laparoscopic cholecystectomy. The pathophysiological process leading to the subtypes of Mirizzi syndrome has been explained by means of a pressure ulcer caused by an impacted gallstone at the gallbladder infundibulum, leading to an inflammatory response causing first external obstruction of the bile duct, and eventually eroding into the bile duct and evolving to a cholecystocholedochal or cholecystohepatic fistula. This article reviews the life of Pablo Luis Mirizzi, describes the earlier and later descriptions of Mirizzi syndrome, discusses the pathophysiological process leading to the development of these uncommon fistulas, reviews the current diagnostic modalities and surgical approaches and finally proposes a simplified classification for Mirizzi syndrome intended to standardize the reports on this condition and to eventually develop a consensual surgical approach to this unexpected and seriously dangerous condition.

Laparoscopic partial cholecystectomy for the difficult gallbladder: a systematic review

BACKGROUND

In the setting of difficult dissection of Calot's triangle during laparoscopic cholecystectomy, conversion is commonly advocated. An alternative approach aimed at preventing bile duct injury is laparoscopic partial cholecystectomy (LPC). The safety and efficacy of this procedure are unclear.

METHODS

A systematic review of the literature was performed independently by three researchers. The outcomes were conversion rate, hospital length of stay (LOS), bile duct injury, bile leak, symptomatic gallstones in the remnant gallbladder, need for reoperation, postoperative endoscopic retrograde cholangiopancreaticography (ERCP), percutaneous intervention, and mortality.

RESULTS

The review included 15 publications, which reported on 625 patients. Four different operative techniques could be distinguished. Conversion to open (partial) cholecystectomy was performed in 10.4 % of the cases. The median LOS was 4.5 days (range, 0-48 days). The most common complication was postoperative bile leak, which occurred in 66 patients (10.6 %). One case of bile duct injury occurred. During the follow-up period, 2.2 % of the patients experienced recurrent symptoms of gallstones. Eight patients (2.7 %) underwent reoperation. Postoperative ERCP was performed for 26 (7.5 %) of 349 patients. A percutaneous intervention was performed for 5 (1.4 %) of 353 patients. Three deaths were described in the reviewed series (1 of pulmonary sepsis and 2 of myocardial infarctions). A rough comparison showed that fewer bile leaks, less need for ERCP, and less recurrent symptoms of gallstones seemed to occur when the cystic duct and gallbladder remnant were closed.

CONCLUSIONS

Literature concerning LPC is scarce. Four different LPC techniques can be distinguished. When a difficult gallbladder is encountered during LC, LPC seems to be a safe and feasible alternative to conversion. Closing of the cystic duct, gallbladder remnant, or both seems to be preferable.

Subtotal Cholecystectomy versus Total Cholecystectomy in Complicated Cholecystitis

Complicated cholecystitis can make dissections around the triangle of Calot difficult with a higher risk of duct and arterial injury. We reviewed a series of patients with cholecystitis receiving either partial or subtotal cholecystectomies and compared it with total cholecystectomies with respect to complications. A retrospective chart review was performed on all subtotal cholecystectomies performed for cholecystitis at University Medical Center of El Paso from June 2004 to December 2010. A similar number of patients who had total cholecystectomies for cholecystitis were selected as a comparison group from that same time period. A total of 116 patients who had subtotal and total cholecystectomies were reviewed (58 patients in each group). There were seven postoperative complications noted in the subtotal cholecystecomy (SC) group versus 14 for the total cholecystectomy (TC) group. Three patients in the SC group had cystic duct leaks, all successfully treated by endoscopic retrograde cholangiopancreatography with biliary stenting. There were two patients who had common bile duct injuries in the TC group and none in the SC group. Two patients had duodenal injuries in the TC group. Subtotal cholecystectomy is a viable alternative to total cholecystectomy in cases of complicated cholecystitis

Laparoscopic or open cholecystectomy in cirrhosis: a systematic review of outcomes and meta-analysis of randomized trials

BACKGROUND

Cholecystectomy is associated with increased risks in patients with cirrhosis. The well-established advantages of laparoscopic surgery may be offset by the increased risk for complications relating particularly to portal hypertension and coagulopathy.

METHODS

A systematic search was undertaken to identify studies comparing open cholecystectomy (OC) and laparoscopic cholecystectomy (LC) in patients with cirrhosis. A meta-analysis was performed of the available randomized controlled trials (RCTs).

RESULTS

Forty-four studies were analysed. These included a total of 2005 patients with cirrhosis who underwent laparoscopic (n= 1756) or open (n= 249) cholecystectomy, with mortality rates of 0.74% and 2.00%, respectively. A meta-analysis of three RCTs involving a total of 220 patients was conducted. There was a reduction in the overall incidences of postoperative complications and infectious complications and a shorter length of hospital stay in LC. However, frequencies of postoperative hepatic insufficiency did not differ significantly.

CONCLUSIONS

There are few RCTs comparing OC and LC in patients with cirrhosis. These studies are small, heterogeneous in design and include almost exclusively patients with Child-Pugh class A and B disease. However, LC appears to be associated with shorter operative time, reduced complication rates and reduced length of hospital stay.

Efficacy and feasibility of laparoscopic subtotal cholecystectomy for acute cholecystitis

Backgrounds/Aims

For patients with acute cholecystitis, conversion from laparoscopic cholecystectomy to open surgery is not uncommon due to possibilities of serious hemorrhage at the liver bed and bile duct injury. Recent studies reported successful laparoscopic subtotal cholecystectomy for acute cholecystitis. The purpose of this study was to determine the efficacy and feasibility of such an operation based on the experience of surgeons at our facility.

Methods

In this study, we enrolled 144 patients who had received either laparoscopic subtotal cholecystectomy (LSC), laparoscopic cholecystectomy (LC), or open cholecystectomy (OC) for acute cholecystitis from January 2004 to December 2009 at the Department of Surgery of our hospital. Their symptoms, signs, operative findings, pathologic results and postoperative results were compared and analyzed.

Results

There were 26 patients in the LSC group 80 in the LC group and 38 in the OC group. There were no differences in mean age, sex, and symptoms of acute cholecystitis. The LSC group showed higher CRP levels (p<0.001) and a higher grade according to the Tokyo criteria (p=0.001). The mean operative time was 115.6 minutes and mean blood loss was 158.9 ml without intra-operative or postoperative transfusion. There weren't any bile duct injuries during the operation. No group suffered bile leakage. Drains were removed 3.3 days after the operation in the LC group, the shortest time compared to the other groups (p<0.001). LC and LSC groups demonstrated shorter postoperative hospital days and time to diet resumption than the OC group (p<0.001).

Conclusions

LSC appears to be a safe and effective treatment in cases of severe acute cholecystitis that require consideration of conversion to open surgery.

The dangers of using stapling devices for cystic duct closure in laparoscopic cholecystectomy

Laparoscopic stapling devices are used widely in laparoscopic surgery, for division of vessels and creation of anastomoses. Their use in the division of a widened cystic duct at laparoscopic cholecystectomy has been reported earlier. We present 3 different complications occurring after division of the cystic duct using the EndoGIA stapling device. A review of the literature has been performed and safe alternative techniques for laparoscopic ligation of the cystic duct are proposed.

Residual gallstone disease - Laparoscopic management

BACKGROUND

A few patients who continue to suffer antecedent symptoms following laparoscopic cholecystectomy (LC) may harbor residual gallstones. The incidence of residual gallstones following cholecystectomy is <2.5%. Many of these patients require a completion cholecystectomy to ameliorate their symptoms.

MATERIALS AND METHODS

We reviewed our experience of laparoscopic re-intervention for residual gallstones over a period of 10 years from January 1998 to December 2007. Twenty six patients underwent Laparoscopic completion cholecystectomy (LCC) for residual gallstone disease. Twelve patients had a previous LC (2 patients - subtotal cholecystectomy) and 9 patients had a previous open cholecystectomy (7 patients - subtotal cholecystectomy). Five patients had previously undergone a cholecystostomy. Diagnostic investigations included abdominal ultrasound, endoscopic ultrasound (EUS), magnetic resonance cholangio-pancreatography (MRCP) and endoscopic retrograde cholangio-pancreatography (ERCP).

RESULTS

Findings included a remnant gallbladder in 3 patients, long cystic duct stump with impacted stone in 18 patients and a contracted gallbladder in 5 patients. All procedures were successfully completed laparoscopically. The mean operative time was 62 minutes and mean blood loss 50cc. Ten patient required abdominal drains postoperatively. Two patients had bilious drainage lasting 9 days and 11 days respectively. One patient died a week following surgery of acute myocardial infarction. Another patient died 6 months later of unrelated causes. The remaining patients have remained symptom free at a mean follow up of 3.2 years (range 7 months to 9 years).

CONCLUSION

The possibility of residual gallstones increases with subtotal cholecystectomy and inadequate dissection of the Calot's triangle in the presence of acute inflammation. Laparoscopic re-intervention for treating residual gallstone disease is feasible and can be safely performed in centers of expertise.

Laparoscopic subtotal cholecystectomy for severe cholecystitis

PURPOSE

To evaluate the efficacy and outcome of laparoscopic subtotal cholecystectomy (LSC) for patients with severe cholecystitis.

METHODS

Between April 1992 and May 2008, 1226 patients underwent laparoscopic cholecystectomy (LC). From 2000 onward 60 patients with severe cholecystitis underwent LSC. The outcomes of LC were compared between patients who underwent the procedure between 1992 and 1999 (group A; n = 643) and those who underwent the procedure between 2000 and 2008 after the introduction of LSC (group B; n = 583), respectively. In Group B, operative outcomes were also compared between the LC and LSC groups.

RESULTS

The incidence of bile duct injury (1.6% vs 0.3%, P = 0.040) and conversion to open cholecystectomy (2.2% vs 0.3%, P = 0.046) was significantly lower in group B. The mean operative time was significantly longer (119.6 min vs 71.0 min., P < 0.001), and the mean blood loss was significantly higher (53.4 ml vs 12.9 ml, P < 0.001) in the LSC group. No significant differences were observed between LC and LSC in the incidence of postoperative morbidities or postoperative hospital stay. No patient had remnant gallstones or gallbladder cancers after a median follow-up of 42 months.

CONCLUSIONS

Laparoscopic subtotal cholecystectomy is safe and effective for preventing bile duct injuries and lowering the conversion rate in patients with technically difficult severe cholecystitis.
