Laparoscopic subtotal cholecystectomy: a review of 56 procedures

Minimally invasive subtotal cholecystectomy. What surgeons need to know

Minimally invasive laparoscopic cholecystectomy is among the most frequently performed abdominal surgeries. Bile duct injury is a significative complication that occurs in about 0.2-0.3% of open procedures and 0.5% of laparoscopic surgeries, with concomitant vasculobiliary injuries in 12-61% of cases. Most of these lesions occurs during challenging severe cholecystitis where the intense inflammation obscures the hepatocystic anatomy. In this case a bailout strategy such as a subtotal cholecystectomy should be considered. Subtotal cholecystectomy is a surgical technique performed to remove a portion of the gallbladder while leaving part of it behind. In such complex cholecystectomies, surgeons should be aware of this technique, and subtotal cholecystectomy should be part of their surgical armamentarium. We aim to familiarize surgeons with bailout techniques like subtotal cholecystectomy and gallbladder emptying for challenging acute cholecystectomy cases to reduce the risk of vasculobiliary injury. This multimedia article provides, a comprehensive step-by-step overview of the different possible minimally invasive subtotal cholecystectomy procedures, we outline five distinct techniques for conducting subtotal cholecystectomy, including some tips and tricks and demonstrates the usefulness of a minimally invasive approach. Finally, we emphasize the importance of carefully choosing between laparoscopic and robotic approaches and suggests using adjunctive tools, such as preoperative indocyanine green, to better identify common bile duct anatomy.

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.

Perioperative strategies for patients undergoing subtotal cholecystectomy: a single-center retrospective review of 102 procedures

BACKGROUND

Calculous gall bladder disease is often handled by laparoscopic cholecystectomy. In cases where a safe dissection of the hepatocystic triangle cannot be carried out, a subtotal cholecystectomy (STC) may be performed. The perioperative management of patients undergoing STC is characterized by limited evidence. This large single-center series explores some of the perioperative aspects and outcomes after STC.

MATERIALS AND METHODS

The study population includes all patients who underwent STC at Oslo University Hospital (Ullevål and Aker Hospitals) from 01.01.2014 to 30.09.2020. A STC was defined as a cholecystectomy where there was a failure to control the cystic duct during surgery. Study variables included demographic data, comorbidities, previous biliopancreatic disease, indication for surgery, perioperative information, subsequent interventions and outcome data.

RESULTS

During the study period, 2376 cholecystectomies were performed, and 102 (4.3%) were categorized as STC. Of all patients with STC, 48 (47.1%) had an intra- or postoperative ERCP during the index hospital admission. The indication for ERCP was bile leak in 37 (42.6%) of the cases. The bile leak resolution rate was 60.0 % in intraoperative ERCP vs 95.7% in postoperative ERCP. Among the STC patients, there were no injuries to the central bile ducts. Later, one patient has undergone a remnant cholecystectomy, following fenestrating STC.

CONCLUSION

STC was a safe bailout strategy for dissection in the hepatocystic triangle in difficult cholecystectomies. Intraoperative ERCP increased procedure time and was associated with a lower rate of leak resolution, as compared to postoperative ERCP.

Evaluating Clinical Outcomes of Laparoscopic Subtotal and Total Cholecystectomy for Complicated Acute Cholecystitis: A Systematic Review and Meta-Analysis

INTRODUCTION

This systematic review and meta-analysis aimed to compare clinical outcomes in patients with complicated acute cholecystitis undergoing laparoscopic total vs subtotal cholecystectomy.

METHODS

This systematic review and meta-analysis was conducted according to PRISMA guidelines and queried PubMed, Embase, ProQuest, Google Scholar, and Cochrane databases from inception to May 2023. The primary outcome was complication rates including common bile duct injury, wound infection, reoperation, bile leak, retained stones, and subhepatic collection, whereas secondary outcomes were in-hospital mortality and hospital length of stay.

RESULTS

A total of 7 studies with 135,233 cases were included for meta-analysis. Patients who underwent laparoscopic total cholecystectomy had a significantly lower risk of postoperative bile leaks (RR: .15; 95% CI: .03, .80) and subhepatic fluid collection (RR: 0.19; 95% CI: .06, .63) and were 2.94 times less likely to die compared to those who underwent subtotal cholecystectomy (RR .34; 95% CI: .15, .77). Patients who underwent subtotal cholecystectomy had significantly longer hospital length of stay (mean difference 1.0 days; 95% CI: .5 days, 1.4 days).

CONCLUSIONS

In adult patients presenting with complicated cholecystitis, management with laparoscopic subtotal cholecystectomy presents a unique complication profile with increased risk of postoperative bile leak and subhepatic fluid collection, in-hospital mortality, and longer hospital length-of-stay when used as an alternative approach to laparoscopic total cholecystectomy. Further research into the most appropriate clinical scenarios and patient populations for the use of the subtotal cholecystectomy approach may prove useful in improving its associated outcomes.

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.

Robot-assisted and fluorescence-guided remnant-cholecystectomy: a prospective dual-center cohort study

BACKGROUND

Abdominal symptoms after cholecystectomy may be caused by gallstones in a remnant gallbladder or a long cystic duct stump. Resection of a remnant gallbladder or cystic duct stump is associated with an increased risk of conversion and bile duct or vascular injuries. We prospectively investigated the additional value of robotic assistance and fluorescent bile duct illumination in redo biliary surgery.

METHODS

In this prospective two-centre observational cohort study, 28 patients were included with an indication for redo biliary surgery because of remnant stones in a remnant gallbladder or long cystic duct stump. Surgery was performed with the da Vinci X® and Xi® robotic system. The biliary tract was visualised in the fluorescence Firefly® mode shortly after intravenous injection of indocyanine green.

RESULTS

There were no conversions or perioperative complications, especially no vascular or bile duct injuries. Fluorescence-based illumination of the extrahepatic bile ducts was successful in all cases. Symptoms were resolved in 27 of 28 patients. Ten patients were treated in day care and 13 patients were discharged the day after surgery.

CONCLUSION

Robot-assisted fluorescence-guided surgery for remnant gallbladder or cystic duct stump resection is safe, effective and can be done in day-care setting.

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).

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.

The second 'gallbladder operation'

Background:

Subtotal cholecystectomy has been reported in 8% and 3.3% of patients undergoing open and laparoscopic cholecystectomy, respectively. According to a recent nationwide survey, the utilisation of subtotal cholecystectomy in the treatment of acute cholecystitis is on the rise. In 1.8% of subtotal cholecystectomies, a reoperation is required. Reoperations for residual gallbladder (GB), gallstones, and related complications accounted for half of the reoperations described in the literature after subtotal cholecystectomy. The purpose of this study was to evaluate the clinical profile, risk of complications, and feasibility of laparoscopic approaches and surgical procedures in patients with recurrent symptoms from a residual GB that necessitated a completion cholecystectomy.

Methods:

Patients who underwent surgery for residual GB with stones and/or complications between January 2007 and January 2020 were included in the study group. A prospectively maintained database was used to review patient information retrospectively. The demographic profile, operation details of the index surgery, current presentation, investigations performed, surgery details, morbidity and mortality were all included in the clinical information.

Results:

There were 13 patients who underwent completion cholecystectomy. The median age was 55 years (22–63 years). Prior operative notes mentioned subtotal cholecystectomy in only seven patients. The average time between the index surgery and the onset of symptoms was 30 months (2–175 months). A final diagnosis of residual GB with or without calculi was made by ultrasound (USG) in 11 patients and by magnetic resonance cholangiopancreatography (MRCP) in two others. Choledocholithiasis (n = 4, 30.7%), acute cholecystitis (n = 2, one with empyema and GB perforation) and Mirizzi syndrome (n = 1) were seen as complications of residual gallstones in seven patients. All 13 patients underwent successful laparoscopic procedures. A fifth port was used in all. A critical view of safety was achieved in 12 patients. Two patients required laparoscopic common bile duct (CBD) exploration for CBD stones. Intraoperative cholangiograms were done in eight patients (61.5%). There were no conversions, injuries to the bile duct or deaths. Morbidity was seen in one. The patient required therapeutic endoscopic retrograde cholangiography for cholangitis and CBD clearance on the fifth post-operative day. The median hospital stay was 4 days (3–7 days). At a median follow-up of 99 months, symptom resolution was seen in all 13 patients.

Conclusion:

Gallstones in the residual GB are associated with more complications than conventional gallstones. The diagnosis requires a high level of suspicion. MRCP is more accurate in establishing the diagnosis and identifying the associated complications, even if the diagnosis is made on USG in most patients. A pre-operative roadmap is provided by the MRCP. For patients with residual GB, laparoscopic completion cholecystectomy is a feasible and safe option.

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.

Which Is More Effective: Laparoscopic or Open Partial Cholecystectomy?

Objective: In laparoscopic cholecystectomy, partial cholecystectomy is usually preferred when the anatomic exploration is not enough to prevent bile duct injury and other complications. Some surgeons choose laparoscopically to perform partial cholecystectomy, whereas others convert to open surgery. In this study, we aim to discuss and compare the effectiveness of laparoscopic partial cholecystectomy (LPC) and open partial cholecystectomy (OPC). Materials and Methods: The data of 4712 patients who underwent laparoscopic cholecystectomy between 2012 and 2020 were reviewed. A total of 98 patients who had partial cholecystectomy were included in the study. Patients were examined in two groups according to whether the procedure was open or laparoscopic. The first group of patients was named the OPC group (n = 52), and the second group of patients was the LPC group (n = 46). The data of the two groups were comparatively analyzed. Results: The mean operative time and the postoperative hospital stay, respectively, were 118.2 minutes and 4.8 days in the OPC group, and 87.3 minutes and 2.55 days in the LPC group (P < .005 and P = .005). It was found that wound infection decreased by 83.1% (P = .026; odds ratio [OR] = 0.169) in the LPC group compared with the OPC group, and the probability of developing incisional hernia decreased by 81.1% (P = .014; OR = 0.189). At least one complication was observed in 17 patients in the OPC group and in 7 patients in the LPC group (P = .045). The probability of developing complications in any patient was 63% lower in the LPC group (P = .049; OR = 0.370). Conclusions: The indications that cause the surgeon to perform partial cholecystectomy are inherently open to complications, regardless of the surgical technique used. However, the laparoscopic operation has advantages such as shorter operation time, shorter postoperative hospital stay, lower risk of wound infection and incisional hernia rate, and lower complication rate than the open procedure. However, if the team performing the surgery does not have enough experience, they should never hesitate to switch to open cholecystectomy.

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.

Is a difficult gallbladder worth removing in its entirety? - Outcomes of subtotal cholecystectomy

Background:

Laparoscopic Cholecystectomy one of the commonest procedures performed worldwide isn't spared from the risks of disastrous iatrogenic complications. In patients with obscured anatomy, the idea of performing a safe total cholecystectomy can be hindered with a high risk of biliovascular injuries. In such a situation STC (subtotal cholecystectomy) comes to the rescue, where the diseased organ can be tackled fairly, without any further damage.

Aims and Objectives:

The primary aim was to look at the immediate and long-term outcomes of subtotal cholecystectomy. Subgroup analysis was done based on demographics, indications and surgical approach.

Materials and Methods:

We reviewed our prospectively maintained computerized operation database over nine years. STC was defined as leaving behind any portion of gallbladder other than the cystic duct. They were subclassified as per the description given by Palanivelu. Patients were evaluated with laboratory and radiological assessment.

Results:

A total of 70 out of 602 patients (11.6%) underwent STC. Dense adhesion at the calot's was the most important reason for STC. Subtype B was the most common. Nine patients (12.85%) had a bile leak in the postoperative period. There were no biliary/vascular injuries and 30-day mortality was zero. 22.8% developed SSI (surgical site infection). Over a median follow up of 38 months (range 5-98), clinical examination, LFT and USG revealed no abnormality in any of the patients.

Conclusion:

Subtotal cholecystectomy is a useful alternative during difficult gallbladder surgery. It should be considered early into the procedure preferably prior to conversion to an open procedure. Biliovascular injuries can be avoided and the Immediate and long-term outcomes are acceptable.

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.

CONCLUSION

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.

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.

The outcome of laparoscopic subtotal cholecystectomy in difficult cases - A case series

INTRODUCTION

Laparoscopic subtotal cholecystectomy (LSC) is a widely used technique for managing cholelithiasis with severe cholecystitis. The increasing popularity its utilization is due to the good safety profile and acceptable results. This case series evaluates the short- and long-term results of Indonesian patients who underwent LSC with an objective to determine whether the procedure can be a standard approach for difficult cholecystectomy in our institution.

PRESENTATION OF CASE

Thirty-four Indonesian patients (26 men, 8 women) with the mean age of 54.6 years (median 54 years, range 30-84 years) who underwent LSC were retrospectively analyzed. Nineteen patients are suffering from type II diabetes mellitus and fourteen patients with suspected choledocoholithiasis underwent ERCP prior to LSC. The major postoperative diagnosis was acute cholecystitis (16 patients), followed by gallbladder empyema (10 patients), chronic cholecystitis (5 patients), history of cholangitis (1 patient), Mirizzi's syndrome (1 patient) and stone retention post-ERCP (1 patient).

DISCUSSION

The mean operating time was 158minutes (median 150minutes, range 60-240minutes), mean length of hospital stay of 4.6days (median 3days, range 2-33days) and drain usage for 3.6days (median 3.0days, range 1-19days). Postoperatively there was one case of bilioenteric fistula, one case of stone retention and two cases of prolonged upper gastrointestinal symptoms. There is no case of biliary leakage, peritonitis or wound infection.

CONCLUSION

The outcome of LSC in this case series is comparable with other publications showing a general favorability of LSC. Further studies are needed to elucidate the clinical benefits of several LSC technical points such as stump closure, posterior wall diathermy and drain usage. Based on this preliminary finding, LSC can be applied as a standard procedure for difficult cases in our institution.

Utility of Laparoscopic Subtotal Cholecystectomy with or without Cystic Duct Ligation for Severe Cholecystitis

We use open cholecystectomy (OC) to treat severe cholecystitis in cases in which we are worried that inflammation might cause anatomical changes in Calot's triangle. Furthermore, in cases of severe cholecystitis in which marked inflammation leads to fibrosis, we perform subtotal cholecystectomy (SC), i.e., incomplete gallbladder resection. Laparoscopic SC (LSC) without cystic duct dissection is considered to be effective at reducing the incidence of serious complications in patients with severe cholecystitis. The cases of 246 patients who underwent cholecystectomy for benign gallbladder disease between January 2011 and May 2015 were evaluated retrospectively. Of these patients, 14 were treated with LSC, and 19 underwent OC. Moreover, three patients in the LSC group underwent LSC without cystic duct ligation because it was considered that it would be difficult to dissect and ligate the cystic duct. The LSC group suffered significantly less intra-operative blood loss than the OC group. However, the operative times of the two groups were similar. Moreover, the duration of the postoperative hospitalization period was significantly shorter in the LSC group than in the OC group. Next, we compared the long-term outcomes of the SC and total cholecystectomy groups, regardless of the surgical method. No cases of cholecystitis or gallbladder cancer were encountered in either group. It is suggested that LSC is safe, effective, and helps to prevent serious complications in cases of severe cholecystitis that require conversion to OC, regardless of whether cystic duct ligation is performed.

Damage-control laparoscopic partial cholecystectomy with an endoscopic linear stapler

OBJECTIVE

Several damage-control procedures have been described in the literature in case of severe Calot's triangle inflammation and fibrosis. In this report, we describe patients who underwent laparoscopic partial cholecystectomy using an endoscopic linear stapler.

MATERIALS AND METHODS

Five patients with acute cholecystitis underwent laparoscopic partial cholecystectomy in our clinic between January - December 2011. All patients had severe fibrosis and inflammation of Calot's triangle. The anterior and posterior walls of the gallbladder were totally resected if possible. The gallbladder was transected at its neck or Hartmann's pouch, leaving a remnant gallbladder pouch behind.

RESULTS

Five patients had laparoscopic partial cholecystectomy with an endoscopic linear stapler. The main symptom of all patients on admission to the emergency room was abdominal pain. The mean time for the surgical procedure was 140 minutes (range, 120-180 minutes). Inflammation and fibrosis of Calot's triangle was detected in all patients during surgery and a phlegmonous gallbladder was detected in one patient. Surgical drains were used in all patients and no biliary leakage was detected. Remnant common bile duct calculi were detected in one patient and this patient underwent endoscopic retrograde cholangiopancreatography one month after surgery.

CONCLUSIONS

When a reliable view of Calot's triangle cannot be obtained due to severe inflammation and fibrosis during laparoscopy, laparoscopic partial cholecystectomy seems to be a safe and feasible alternative to open surgery with an acceptable morbidity rate.

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.

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.

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.

Use of stapling devices for safe cholecystectomy in acute cholecystitis

Many techniques are described for the ligation of a difficult cystic duct (CD). The aim of this study is to assess the effectiveness and safety of stapling of a difficult CD in acute cholecystitis using Endo-GIA. From January 2008 to June 2012, 1441 patients with cholelithiasis underwent laparoscopic cholecystectomy (LC) at the Department of General Surgery, Haydarpasa Numune Education and Research Hospital. Of these, 19 (0.62%) were identified as having a difficult CD and were ligated using an Endo-GIA stapler. All patients were successfully treated with a laparoscopic approach. The length of hospital stay was 3.4 days. There were umbilical wound infections in 4 patients (21%). The length of follow-up ranged from 1.0 to 50.4 months. In conclusion, Endo-GIA is a safe and easy treatment method for patients with a dilated and difficult CD. The cystic artery should be isolated and ligated if possible before firing the Endo-GIA stapler. If isolation and stapling are not possible, fibrin sealant can be applied to avoid bleeding. The vascular Endo-GIA can be applied in a large CD, but for acute cholecystitis with an edematous CD, the Endo-GIA roticulator 4.8 or 3.5 stapler is preferred.

Single-incision laparoscopic cholecystectomy for cholecystitis requiring percutaneous transhepatic gallbladder drainage

PURPOSE

Single-incision laparoscopic cholecystectomy (SILC) has been performed for patients with gallbladder stones but without acute cholecystitis. We report our experience of performing SILC for patients with cholecystitis requiring percutaneous transhepatic gallbladder drainage (PTGBD).

METHODS

We performed SILC via an SILS-Port with additional 5-mm forceps through an umbilical incision in ten patients with cholecystitis requiring PTGBD.

RESULTS

All procedures were completed successfully. The mean operative time was 124 min (range 78-169 min) and there were no intraoperative or postoperative complications. The mean postoperative hospital stay was 2.7 days. All patients were satisfied with the cosmetic results.

CONCLUSIONS

Our procedure may represent an alternative to conventional laparoscopic cholecystectomy (CLC) for patients who fervently demand the cosmetic advantages, despite cholecystitis requiring PTGBD. SILC should be performed carefully to avoid bile duct injury because the only advantage of SILC over CLC is cosmetic.

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.

Cholecystomucoclasis: revaluation of safety and validity in aged populations

Background

We evaluated the safety and validity of cholecystomucoclasis (CM) and compared its intraoperative characteristics with those of standard cholecystectomy (SC).

Methods

We enrolled 174 patients who underwent cholecystectomy and retrospectively evaluated the outcomes of patients in the SC and CM groups.

Results

Significant differences in age (71.1 vs. 61.9 years), American Society of Anesthesiologists physical status (ASA-PS), and serum C-reactive protein levels (CRP) (18.1 vs. 4.7 mg/dL) were observed between the CM and SC groups. Conversely, no significant differences were observed in the operation time (129 vs. 108 min), amount of blood loss (147 vs. 80 mL), intraoperative complications (0% vs. 5.7%), or duration of hospital stay (13.2 vs. 8.9 days) between the 2 groups. A high conversion rate (35.3%), postoperative complications (33%), and frequent drain insertions (94%) were observed in the CM group.

Conclusions

CM is a safe and valid surgical procedure and surgeons should not hesitate to transition to CM for patients who are of advanced age, in poor general condition (high ASA classification), or have high levels of serum CRP.

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.

Mirizzi syndrome

Mirizzi syndrome is an important complication of gallstone disease. If not recognized preoperatively, it can result in significant morbidity and mortality. Preoperative diagnosis may be difficult despite the availability of multiple imaging modalities. Ultrasonography (US), CT, and magnetic resonance cholangiopancreatography (MRCP) are common initial tests for suspected Mirizzi syndrome. Typical findings on US suggestive of Mirizzi syndrome are a shrunken gallbladder, impacted stone(s) in the cystic duct, a dilated intrahepatic tree, and common hepatic duct with a normal-sized common bile duct. The main role of CT is to differentiate Mirizzi syndrome from a malignancy in the area of porta hepatis or in the liver. MRI and MRCP are increasingly playing an important role and have the additional advantage of showing the extent of inflammation around the gallbladder that can help in the differentiation of Mirizzi syndrome from other gallbladder pathologies such as gallbladder malignancy. Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard in the diagnosis of Mirizzi syndrome. It delineates the cause, level, and extent of biliary obstruction, as well as ductal abnormalities, including fistula. ERCP also offers a variety of therapeutic options, such as stone extraction and biliary stent placement. Percutaneous cholangiogram can provide information similar to ERCP; however, ERCP has an additional advantage of identifying a low-lying cystic duct that may be missed on percutaneous cholangiogram. Wire-guided intraductal US can provide high-resolution images of the biliary tract and adjacent structures. Treatment is primarily surgical. Open surgery is the current standard for managing patients with Mirizzi syndrome. Good short- and long-term results with low mortality and morbidity have been reported with open surgical management. Laparoscopic management is contraindicated in many patients because of the increased risk of morbidity and mortality associated with this approach. Endoscopic treatment may serve as an alternative in patients who are poor surgical candidates, such as elderly patients or those with multiple comorbidities. Endoscopic treatment also can serve as a temporizing measure to provide biliary drainage in preparation for an elective surgery.

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.

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.

The "inside approach of the gallbladder" is an alternative to the classic Calot's triangle dissection for a safe operation in severe cholecystitis

BACKGROUND

External dissection of Calot's triangle and the gallbladder associated with complete cholecystectomy is considered the gold standard technique to achieve a safe cholecystectomy. However, in severe acute or chronic cholecystitis, the laparoscopic application of this standard technique may be technically difficult, with an increased risk of bile duct injury, even in the hands of an experienced surgeon.

METHODS

In a consecutive series of 552 cholecystectomies, 39 patients (7.1%) with difficult local conditions within Calot's triangle, such as gangrenous cholecystitis (three patients), severe scleroatrophic cholecystitis with or without anomalous right hepatic duct (24 and 10 patients, respectively), or Mirizzi syndrome (seven patients), underwent a routine exclusive "endovesicular approach" as an alternative to dissection of Calot's triangle prior to further subtotal cholecystectomy. All patients were examined by control cholangiography 3 months postoperatively to confirm the safety of the technique.

RESULTS

The operation was well tolerated by all patients with only 15.4% minor complications. Intraoperative cholangiography was feasible in 79.5%. There were no postoperative biliary or infectious complications. At 4.3 months follow-up, all patients were symptom-free, except for two patients (5.1%) with residual common bile duct stones which were successfully treated by endoscopic sphincterotomy.

CONCLUSIONS

An endovesicular approach for gallbladder dissection followed by subtotal cholecystectomy is a safe alternative to the classic Calot's dissection in the case of severe cholecystitis or difficult local conditions. This technique is recommended as an attractive solution to prevent bile duct injury, particularly when severe inflammation is associated to extrahepatic anatomic variants of the biliary tree.

Laparoscopic subtotal cholecystectomy: initial experience with laparoscopic management of difficult cholecystitis

AIM

Laparoscopic cholecystectomy (LC) is now accepted as the 'gold standard' procedure for cholecystectomy. However, a significant proportion of patients with complicated cholecystitis are still converted to 'open' to complete the procedure. Laparoscopic subtotal cholecystectomy (LSC) is an option, which is still too infrequently used.

METHODS

A single surgeon in our NHS trust has performed 1150 LCs since September 1999. The procedure was converted to LSC in 52 cases (4.52%) due to complicated cholecystitis. The data were collected and prospectively analysed for any morbidity or complications in the peri-operative period.

RESULTS

At the initial presentation, 21 patients (40.38%) were diagnosed with recurrent biliary colic, 24 patients (46.15%) had acute cholecystitis, 6 patients (11.53%) had jaundice, and 1 patient (1.92%) had peritonitis due to gallbladder (GB) perforation. Twenty-six cases (50%) were performed as emergencies, i.e. within one week of symptoms, and 26 (50%) were planned for surgery within four weeks after symptoms started. The cystic duct or Hartmann's pouch stump was closed using endo-loop application in 34 (65.38%), intracorporeal suturing of stump of Hartmann's pouch in 13 (25%), and closure of cystic duct opening in the Hartmann's pouch by purse-string suturing in 5 cases (9.62%).

CONCLUSION

LSC is a safe option in treating gallstone disease when inflammation or fibrosis precludes conventional dissection of Calot's triangle. LSC can clearly help reduce morbidity associated with open laparotomy.

Laparoscopic treatment of stone recurrence in a gallbladder remnant: report of an additional case and literature review

Cholecystectomy is an effective treatment of gallstones. Nevertheless, recurrence of biliary symptoms following cholecystectomy, either laparotomic or laparoscopic, is quite common. Causes are either biliary or extrabiliary. Symptoms of biliary origin chiefly depend on bile duct residual stones or strictures. Rarely, they depend on stone recurrence in a gallbladder remnant. Diagnosis of gallstone recurrence in gallbladder remnant is difficult, mainly arising from ultrasonography, computed tomography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography.Incomplete gallbladder removal may be either voluntary or inadvertent: in the first case, it is performed to remove gallstones without dissecting a difficult Calot's triangle or an excessively bleeding posterior wall of gallbladder caused by liver cirrhosis. Available data do not support the hypothesis that laparoscopic cholecystectomy entails an increased incidence of this condition, in spite of some opposite opinions. Treatment of lithiasis in gallbladder remnants is chiefly surgical. Although technically demanding, completion cholecystectomy can be safely performed in a laparoscopic way. We report a case of stone relapse in a gallbladder remnant, discovered 16 years following laparoscopic cholecystectomy and successfully treated by laparoscopic completion cholecystectomy. We furthermore review literature data in order to ascertain whether recent large diffusion of laparoscopic surgery causes an increase of such cases.

A case of Mirizzi's syndrome mimicking carcinoma: the role of CBD-stenting for easy surgical management

Mirizzi's syndrome accounts for an important risk for bile tree injury during surgery, since preoperative diagnosis is missed in half of the cases and is often difficult to differentiate from carcinoma. A 79-year-old male, with a known history of cholelithiasis, was admitted with a progressive obstructive jaundice over 20 days, without pain, fever, or other symptoms. Magnetic resonance cholangiopancreatography described possible microlithiasis of the distal bile duct, but on endoscopic retrograde cholangiopancreatography (ERCP), an irregular stenosis was detected under the junction of hepatic ducts, which was described as possibly neoplastic. A temporary stent was placed and the patient was referred for surgery. On first view the gallbladder appeared hard, embedded in adhesions, giving the impression of an unresectable tumor and the bile duct was not approachable. After a fundus-down incision of the gallbladder multiple stones were extracted. Frozen biopsies from the gallbladder wall were negative. The incision was extended towards the gallbladder neck and a large communication with the common bile duct (CBD) was revealed. A difficult partial cholecystectomy was performed, followed by cholecystojejunostomy with a Roux-en-Y jejunal loop. The patient had a totally uneventful postoperative course. Stent removal was succeeded endoscopically 1 month later. The importance of preoperative ERCP and CBD stenting is highlighted in this article. ERCP may have failed to distinguish Mirizzi's syndrome from carcinoma, however the stent placement saved the cardiologically compromised patient from further surgical manipulations. Therefore, in ambiguous cases, whatever the final diagnosis turns to be, either carcinoma or Mirizzi's syndrome, CBD stenting can be useful for the final management of the patient.

Laparoscopic subtotal cholecystectomy as an alternative procedure designed to prevent bile duct injury: experience of a hospital in northern China

PURPOSE

Experience and advances in laparoscopic techniques have made laparoscopic subtotal cholecystectomy (LSTC) a feasible option even in complex procedures. We report our experience of performing LSTC in the management of complicated cholecystitis.

METHODS

Among 1558 patients scheduled to undergo laparoscopic cholecystectomy (LC) in our institute between July 2004 and December 2007, 48 underwent LSTC for complicated cholecystitis. We describe our tailored approach and the techniques we used to accomplish this.

RESULTS

All 48 patients underwent retrograde cholecystectomy. Twenty (41.6%) required an additional port (the fourth port) to obtain adequate exposure of the hilum, 39 (81.3%) required suturing of the gallbladder infundibular remnant, and 4 (8.33%) experienced local complications. The mean operative time of LSTC was 61.7 +/- 17.5 min, the estimated operative blood loss was 72.0 +/- 32.8 ml, the time to resume oral intake was 27.8 +/- 14.9 h, and the mean postoperative hospital stay was 4.5 +/- 1.3 days. There was no bile duct injury or mortality in this series.

CONCLUSION

Laparoscopic subtotal cholecystectomy is a safe and feasible alternative to conversion to open surgery during difficult laparoscopic cholecystectomy for patients with complicated cholecystitis. However, we emphasize that only experienced laparoscopic surgeons should perform this procedure when complete removal of the gallbladder is not possible.

Partial Cholecystectomy in the Setting of Severe Inflammation is an Acceptable Consideration with Few Long-Term Sequelae

Open cholecystectomy is infrequently performed. For the general surgeon, open cholecystectomy is typically performed when a great degree of inflammation precludes safe laparoscopic removal. The degree of inflammation can also lead to an unacceptable risk of common bile duct injury during the dissection of the triangle of Calot. In this situation, the extent of dissection and amount of resection is not well established. We undertook a retrospective review and follow-up telephone questionnaire of all partial cholecystectomies performed. Partial cholecystectomy was performed in 26 cases with open, laparoscopic converted to open, and laparoscopic techniques. Postoperative complications occurred in seven (27%) patients with three (12%) experiencing more than one complication. There was a bile leak in three (12%), subhepatic abscess in three (12%), wound infection in two (8%), and retained common duct stone in one (4%). There were no common bile duct injuries and no deaths. Telephone interviews were conducted with 19 (73%) patients. Average length of follow up was 314 days. At the time of last contact, no ongoing complaints attributable to biliary pain were present. Our data suggest that partial cholecystectomy in the setting of severe inflammation is a reasonable operation with few long-term sequelae, good clinical results, and satisfactory symptom relief.

Liver transection using vascular stapler: a review

The clinical experience using a novel technique of liver resection with vascular staplers for dissection of hepatic parenchyma, was documented most recently in a prospective manner. These data have clearly demonstrated for the first time that stapler hepatectomy is a safe and fast dissection technique in major liver surgery (e.g. hepatectomy) which is feasible in a routine clinical setting.

Delayed laparoscopic subtotal cholecystectomy in acute cholecystitis with severe fibrotic adhesions

BACKGROUND

Conversion rate to open surgery is higher for patients with acute cholecystitis than in those without acute cholecystitis. We attempted to develop a laparoscopic subtotal cholecystectomy to decrease this conversion rate.

METHODS

From 2000 to 2005, laparoscopic cholecystectomy for acute cholecystitis was performed in 60 patients (22 women, 38 men). Patients were divided into two groups: group A (2000 to 2002, n = 22) and group B (2003 to 2005, n = 38). When significant difficulty was encountered dissecting the gallbladder from its bed, we incised the gallbladder wall leaving the posterior wall and cauterizing the remnant mucosa (subtotal cholecystectomy, SC-1). When dissection of the gall bladder neck and triangle of Calot was difficult, the neck of the gallbladder was sutured despite clipping (SC-2).

RESULTS

Mean duration from onset of symptoms to operation was 55.3 +/- 52.0 days. SC-1 was performed in 8 patients in group A and 18 patients in group B. SC-2 was performed in three patients in Group B. Conversion rate was 18.1% (4/22) in group A and 0% (0/38) in group B, compared to 0.4% (1/221) for patients without acute cholecystitis. No complications were associated with ablated gallbladder mucosa.

CONCLUSION

Laparoscopic subtotal cholecystectomy offers safe and effective treatment for acute cholecystitis. The conversion rate in group B is decreased by avoiding hazardous dissection of the cystic duct.

Laparoscopic subtotal cholecystectomy without cystic duct ligation

BACKGROUND

Cholecystectomy is made hazardous by distortion of the anatomy of Calot's triangle by acute or chronic inflammation. Laparoscopic subtotal cholecystectomy (LSTC) without cystic duct ligation is an alternative to conversion to open surgery in difficult cases.

METHODS

This prospective study included all cholecystectomies performed in a district general hospital upper gastrointestinal unit between 2003 and 2005, after the introduction of LSTC.

RESULTS

Of 889 laparoscopic cholecystectomies, 28 LSTCs without cystic duct ligation were performed in 18 men and ten women of median age 68 years. Median operating time was 90 min and median duration of hospital stay was 3 days. Two temporary bile leaks resolved spontaneously on days 14 and 19. Three patients required endoscopic retrograde cholangiopancreatography, extraction of bile duct stones and stent insertion for persistent leaks. All five bile leaks were expected from peroperative findings. One patient had a myocardial infarction and one developed a subphrenic abscess. There were no deaths. Open conversion rates were reduced from 5.0 per cent in 1997-2002 to 0.3 per cent in 2005 (P < 0.001).

CONCLUSION

LSTC without cystic duct ligation is an alternative to open conversion when dissection of Calot's triangle is hazardous. Bile leaks are predictable and readily managed.

The use of laparoscopic subtotal cholecystectomy for complicated cholelithiasis

BACKGROUND

The risk of damage to the bile duct and structures in the hilum of the liver is significant when Calot's triangle cannot be safely dissected during laparoscopic cholecystectomy, and conversion to an open procedure often is performed. This is more common during emergency surgery, but may not render the procedure any easier. Traditionally, open subtotal cholecystectomy was performed, but with the advent of laparoscopic surgery, this has fallen from favor. The authors report their experience using laparoscopic subtotal cholecystectomy to avoid bile duct injury and conversion in difficult cases.

METHODS

Laparoscopic subtotal cholecystectomy, performed when the cystic duct cannot be identified safely, consists of resecting the anterior wall of the gallbladder, removing all stones, and placing a large drain into Hartmann's pouch. The notes for all patients who underwent a laparoscopic subtotal cholecystectomy between 1 September 2001 and 31 December 2004 were retrospectively analyzed.

RESULTS

Subtotal cholecystectomy was performed in 26 cases including 13 emergency and 13 elective procedures. The median age of the patients (15 women and 11 men) was 68 years (range, 36-86 years). The indications were severe fibrosis in 16 cases, inflammatory mass or empyema in 8 cases, and gangrenous gallbladder or perforation in 2 cases. The median postoperative inpatient stay was 5 days (range, 2-26 days). Five patients underwent postoperative endoscopic retrograde cholangiopancreatography: four for persistent biliary leak and one for a retained common bile duct stone. One patient required laparotomy for subphrenic abscess, and one patient (American Society of Anesthesiology [ASA] grade 4, presenting with biliary peritonitis) died 2 days postoperatively. One patient required a subsequent completion laparoscopic cholecystectomy for a retained gallstone. One patient had a chest infection, and two patients experienced port-site hernias.

CONCLUSIONS

Laparoscopic subtotal cholecystectomy is a viable procedure during cholecystectomy in which Calot's triangle cannot be dissected. It averts the need for a laparotomy.

Partial Cholecystectomy as a Safe and Viable Option in the Emergency Treatment of Complex Acute Cholecystitis: A Case Series and Review of the Literature

Partial cholecystectomy (PC) is an alternative choice to standard cholecystectomy in situations with increased risk of Calot's components injury. We reported our experience with the patients treated with PC and reviewed the literature. Fifty-four patients with complex acute cholecystitis underwent PC, including conventional partial cholecystectomy (CPC; n = 48) and laparoscopic partial cholecystectomy (LPC; n = 6). The clinical diagnosis was verified by ultrasonography. In addition, we reviewed 1190 published cases (1972–2005) who underwent a “nonconventional” surgery for severe cholecystitis, including cholecystostomy, CPC, or LPC. Review of the literature, including our cases, showed a male:female ratio of 1.3:1. The major operative indication was severe acute cholecystitis. Procedures included cholecystostomy (65.8%) and PC (34.2%). In the follow-up (n = 1190), biliary leak (4.8%), retained stones (4.6%), recurrent symptoms (2.3%), wound infections (1.9%), persistent biliary fistula (0.9%), and prolonged biliary drainage (0.2%) were found, with an overall mortality rate of 9.4 per cent. In 133 patients, because of postoperative complications ( e.g., recurrent symptoms, remaining common bile duct stones, or persistence of bile fistula), reoperation was necessary, including 121 cases (90.1%) of cholecystectomy, whereas the other 11 patients underwent other procedures such as common bile duct exploration or closure of the fistula. The surgical trend for complex acute cholecystitis treatment has been changed from only cholecystostomy to a spectrum of cholecystostomy, CPC, and LPC with the progressive increase of PC. The proportion of the LPC compared with CPC has also increased during recent years. It seems that PC is a safe procedure for treating complicated acute cholecystitis. Whether the indication and need for alternative techniques to standard cholecystectomy is changing should be evaluated in future studies.

Mirizzi syndrome: history, present and future development

BACKGROUND

Mirizzi syndrome was reported in 0.3-3% of patients undergoing cholecystectomy. The distortion of anatomy and the presence of cholecystocholedochal fistula increase the risk of bile duct injury during cholecystectomy.

METHODS

A Medline search was undertaken to identify articles that were published from 1974 to 2004. Additional papers were identified by a manual search of the references from the key articles.

RESULTS

A preoperative diagnosis was made in 8-62.5% of cases. Open surgical treatment gave good short-term and long-term results. There was a lack of good data in laparoscopic treatment. Conversion to open surgery rates was high, and bile duct injury rate varied from 0 to 22.2%.

CONCLUSION

A high index of clinical suspicion is required to make a preoperative or intraoperative diagnosis, which leads to good surgical planning to treat the condition. Open surgery is the gold standard. Mirizzi syndrome should still be considered as a contraindication for laparoscopic surgery.
